First thing every morning the pupils of St Dunstan's are required to attend assembly. The strict headmistress insists on their undivided attention but it's so boring that they fidget in their seats. The boys would rather be out on the sports field proving their manly prowess. The girls would prefer to be gossiping about the boys in the corridors. They are all unaware that today is going to be very different. Indeed, for some of them it will be a life-changing experience that they'll never forget.

The headmistress reads out the register in a dull monotone, her voice echoing around the cavernous assembly hall. Her keen eyes scan the room to make sure nobody is getting up to mischief.

The students answer as their names are called, pretending to pay attention but their minds are elsewhere. it looks to be just another normal day at St Dunstan's.

"Simpson?" She calls out, eager to get this particular chore done as she has lots of important news to share with them and time is moving on.

Cassy glances over at her best friend Veronica, happy that they'll be sitting next to each other for their first lesson. Biology is so tedious but at least they'll be able to pass notes to each other and have some fun.

Vincent can't help but look at Cassy. He's always fancied her and wonders if today she'll finally notice him. As the school soccer captain he's used to the girls fawning over him but Cassy is different and seems immune to his charms.

"Williams?" The headmistress finally gets to the end of the list of names with a sigh of relief.

"That concludes the register," she announces, "now there are some important announcements."

"We have a new teacher today, Miss Marchmont." She waits for the news to sink in.

"Her first lesson will be the Biology class with the girls only, straight after assembly."

Veronica and Cassy exchange a look. How exciting! Hopefully the new teacher will be more interesting than old Miss Withering.

"Anyone thinking of cheeking her should think twice. I have given her the authority to punish any pupil being cheeky. You don't want detention do you?"

The girls all smile sweetly like butter wouldn't melt in their mouths. The boys wonder why they aren't going to Biology with the girls.

"Boys you will be excused Biology because of your annual physical examination today."

Her words fill young Martin Simpson with dread. Being naturally shy, he is very self-conscious when he has to get undressed. It's bad enough in the locker room with the other lads but the thought of having to do it in front of the school nurse makes him feel queasy.

Seeing an opportunity to tease him, his friend Aiden turns round.

"There you are Simmo, you can ask her to find your knob for you!"

"Ha ha," he laughs sarcastically, "shut it Palmer you twerp."

Joining in the fun, Vincent leans over and begins coughing jokingly right in his ear.

Logan knows how much Martin will hate the idea of a physical and can't resist winding him up.

"Cough and drop Simmo, cough and drop!" He can tell by the look on his friend's face that he's had the desired effect.

The headmistress continues unabated, "these will take place in room 1 on the second floor."

Vincent, Aiden and Logan snigger while Martin tries to steady his nerves. If only there was some way to get out of it. But he knows if he skips the physical there will be repercussions.

Realising that not everyone is listening to her, the headmistress calls out, "Quieten down at the back! No talking!"

The boys all shut up immediately, not wanting to risk a detention. They know better than to cross the stern woman in charge.

"Now girls, gather your things and go off to Biology. Boys wait here." As soon as she finishes speaking there is a scraping of chairs on the floor as the girls jump up.

They grab their bags, eager to see what the new teacher is like. It'll be nice to have a lesson without the boys mucking about and distracting them.

Despite their bravado, all the boys are nervous about the impending inspection and sit uncomfortably waiting for further instruction. Martin is petrified and hopes desperately that something will happen so it is cancelled.

Cassy's bag is caught round her chair leg and she dithers trying to untangle it while the other girls rush to the door.

The rest of them burst out of the room and rush up the stairs to the second floor chattering excitedly.

They want to be on time and create a good impression with their new teacher so they can win her round.

They breeze past the door to the nurse's room glad that they won't have to undergo the indignity of an examination like the boys.

Cassy hurries up the stairs to catch up with her classmates hoping she'll make it in time.

As Cassy comes into the corridor Nurse Bleifrei comes out of her room. She has a lot of boys to see today and is keen to get started.

"Oh little girl!" She says stopping Cassy in her tracks.

"Be a darling and ask 'erm..."

She consults her clipboard, "Martin Simpson to come up right away."

Always ready to help out and win favour with the school officials, Cassy readily agrees.

She calls out to Veronica to let her know she's running an errand for the nurse as the others pile into the Biology room.

Then she skips off downstairs to fetch Martin seeing an opportunity to impress the headmistress.

Miss Marchmont is pleased to see the girls have arrived promptly. She believes in strict discipline and punctuality and so far they all seem to be behaving impeccably.

Tanya and Dawn make their way to their desk wondering if today's lesson will be different from the usual copying of stuff down from the blackboard.

Veronica walks meekly past the new teacher projecting an air of innocence that belies her mischievous nature.

The girls get out their books and take their seats, a sense of anticipation fills the room.

"Good morning girls!" Says Miss Marchmont loudly. She's looking forward to her first day at St Dunstan's and has a special surprise for the Biology lesson she can't wait to tell them about.

"I'm Miss Marchmont," she continues, indicating to where her name is written on the blackboard, "and I'll be teaching Biology here at St Dunstan's."

"Good morning Miss Marchmont," they all intone in unison.

"Good," she says, pleased to be teaching such a well behaved class of girls, "today's lesson is Human Male Anatomy. Please turn to page 69 of your text books."

The girls flip through their books excitedly - suddenly finding a renewed interest in Biology.

"Now in order to help you study this subject we will shortly be joined by a MALE MODEL!"

The girls all giggle and murmur to one another - thrilled at the thought of something to liven up a dull lesson. Miss Marchmont gives it a moment for the information to sink in before continuing.

"Now girls, I want you to be very sensible about this because the model is costing the school a lot of money to hire. I want you to get the most out of this lesson."

She walks over to shut the door so they won't be disturbed.

Veronica pipes up: "Miss Marchmont, Cassy isn't here yet!"

"Oh?" Questions the teacher frowning and wondering why one of her students is tardy for her lesson.

"She had to bring someone up from downstairs," the girl explains - wanting to make sure her friend doesn't get into trouble.

"Oh," says Miss Marchmont thinking for a minute. "Good. I see." She leaves the door open in anticipation of her arrival.

The headmistress flicks through her schedule trying to make sense of it all. The boys whisper amongst themselves wondering exactly what the physical examination will entail.

Vincent is just telling Martin that the nurse will laugh when she sees how small his penis is, when the door to the assembly hall opens.

Cassy marches in confidently and heads over to the headmistress.

The boys watch her uneasily, guessing the reason behind her visit.

The headmistress smiles when she sees one of her best students approaching. "Miss. Miss," says Cassy eagerly.

"The nurse wants Martin Simpson brought up." She smiles brightly, keen to impress.

"Thank you Cassy," says the headmistress then turns to the boys, "Simpson? Martin Simpson?"

The others all turn to look at him with smug grins on their faces - glad it's not them who's been chosen - and Martin's stomach turns summersaults. Why did he have to be the one picked to go first? He starts to sweat as he imagines having to remove his clothing in front of the female nurse. Surely there must be some way of getting out of this?

The girls in the Biology class are thrilled to hear that Miss Marchmont has organised a male model to assist with their anatomy lesson. It's certainly a lot more exciting that looking at diagrams in dry old textbooks. They whisper excitedly amongst themselves, but Veronica wonders what has become of her friend Cassy. For the boys it looks like today is going to be a lot less fun. As they wait to be called for their annual physical they cannot help but worry just what it will entail. Martin Simpson is the first one up and his stomach does summersaults at the thought of it.

Mumbling "Yes Miss" feebly, Martin gets out of his chair and grabs his bag as Cassy disappears out of the door. His legs feel like they are made of lead as he slowly walks after her.

He takes a deep breath, trying to steady his nerves and prepare himself for what's to come.

The headmistress looks up at the clock, then down at her schedule. Time is moving on and she has things to do. "Actually," she calls out to the remaining pupils, "all you boys follow them."

"I can't wait with you any more, I have an appointment in a few minutes," she urges and the boys scramble to get their things and head off.

They pile out of the assembly hall wanting to get the unpleasant chore of the physical over and done with as quickly as possible.

Martin struggles to keep up with Cassy who walks purposefully down the corridor. Now she's done what the nurse asked she's lost all interest in Martin and is keen to get to Biology and see what the new teacher is like.

Martin sees a sign on the wall and his heart skips a beat. Just seeing the word written down makes him feel queasy.

He watches Cassy disappear into the room next door and stands there wondering what to do. Should he knock on the nurse's door?

Wanting to put off the dreaded examination for as long as possible he decides to sit and wait till the nurse comes out. Anything to postpone having to take his clothes off in front of her.

He sits there nervously, his mind running through all the possible things the nurse might ask him to do. He dreads the thought of being naked in her presence - what if she laughs at him? Or worse still, what if he becomes aroused?

In the Biology room, Veronica, Tanya and Dawn studiously look at their text books and take down notes. Miss Marchmont comes across as very strict and they don't want to anger her on her first day.

Cassy rushes in and heads straight up to the new teacher. She hopes Veronica has explained why she is late.

"Ah!," Says Miss Marchmont, "You must be Cassy?"

"Yes Miss," she replies happily, guessing that the message was passed on.

Miss Marchmont looks behind Cassie, a puzzled look on her face. Where is the model she booked?

"Where is the young man who came up with you?" She asks.

"Oh," says Cassie, "I think he's sitting out there Miss," she indicates the way she's just come.

"Right, I see," says the teacher, "well sit down and turn your text book to page 69." She heads towards the door briskly.

Cassy joins Veronica and her other classmates and looks over to see what she's missed. She sees that her friend has written the word 'model' in her textbook and wonders shy.

Miss Marchmont heads out into the corridor and sees the young man sitting there. "Ah, there you are!" She says, a note of irritation in her voice. Martin looks round wondering who this fierce looking woman is.

He stands up immediately - too panicked by her sudden appearance to say anything. "You're late young man!" She admonishes and he feels guilty even though he's done nothing wrong.

"It's this room. Come along now." He has no idea who this woman is, but she's clearly in charge and he's too frightened by her authoritative tone to disobey.

Logan, Vincent and Aiden arrive just in time to see Martin disappear through the door. They wonder what he's up to. That boy will do anything to avoid getting a physical!

Cassy looks up from her notes as Miss Marchmont reappears.

Martin falters as he sees the room full of girls all looking at him expectantly. The teacher grabs him by the wrist and leads him to the front of the class.

"Stand at the front there, that's it." A bewildered Martin wonders what is going on. This surely can't be the physical can it?

Cassy is surprised to see meek little Martin Simpson stood before them. Veronica and the others start giggling - well, well, well - so this is to be their model!

"Now girls, come around here so you can get a proper look," Miss Marchmont encourages them.

"Find a space - you can all squeeze in. This is going to be very informative!" Not needing any encouragement the girls leap from their seats.

Martin is petrified as they rush over and surround him. He's never felt so uncomfortable in all his life and is struck dumb with fear.

Outside the school Paul Williams walks purposefully towards the entrance clutching a letter from the headmistress.

It's an invite for an interview for the position of PE teacher. Fresh out of college, the young man is very keen to impress her and get the job.

He glances at his watch. He's running late! He'd better get a move on.

He picks up the pace, not wanting to create a bad first impression. This job could be the making of him!

In the hallway the other boys jump as the door to the infirmary opens and the nurse bustles out.

"Goodness I thought you'd be ready by now," she says, "You need to undress. Blazer, ties - everything has to come off. It's the physical exams today!" She doesn't have time to strip them all individually - they have to be ready when she calls them.

"Martin Simpson?" She enquires consulting her list. Not wanting to get his friend into trouble, Logan answer noncommittally "he was here a minute ago."

The nurse sighs - there's always one boy whose nerves get the better of him and has to rush off to the toilet.

Annoyed she goes back into her room and closes the door. The boys stand up and slowly start to do as they are told.

They don't like the sound of having to remove "everything" but decide they'd better at least take their blazers and ties off.

When they are done they sit back down, fidgeting nervously. What has become of Martin? He'll be in a lot of trouble if he doesn't turn up soon.

In the Biology room Miss Marchmont is flicking through the textbook. "Now then girls. You should have a picture of the male anatomy in your books. I want you to notice the nipples."

She peers at the picture on the page. "It's not a very good diagram is it. So..."

She turns to Martin. "...if you could undress so the girls can make an examination of your nipples." Her words come out as an order.

Martin takes a long gulp. Hearing the word "examination" he decides this must be the physical. And it looks like it's going to be even worse than he thought!

Veronica, Dawn and Tanya look at each other and break into fits of giggles. The thought of the shy boy in front of them having to show them his nipples is just too funny.

"Come on. We don't have all day," says Miss Marchmont sternly, making Martin quake in his shoes.

Feeling physically sick, he reluctantly starts to take off his blazer.

He's aware of the girls around him smirking and lingers as long as he can. He can feel Miss Marchmont's gaze boring into him as he drops his top onto the floor.

Closing his eyes he starts fiddling with his tie. Surely he shouldn't have to take his top off in front of all these girls?

He pauses before undoing his top button and looks fearfully at his classmates, wishing the ground would open up and swallow him whole.

The teacher starts to get impatient. He's charging by the hour so he can jolly well get on with it! "We're not going to get very far at this speed. Take your shirt off!"

Fighting back tears he unbuttons his shirt as instructed. He can feel the girls edging closer and a little trickle of sweat runs down his back.

The girls can barely contain themselves. To be this close to male flesh is thrilling! It's all the more fun witnessing Martin's obvious discomfort.

Martin blinks, desperate not to cry in front of everyone. But he feels horribly exposed as he slowly slides his shirt off.

They all stare at him openly and he can feel their eyes moving across his torso, evaluating him. He briefly considers making a run for it - but the thought of the headmistress' punishment if he does keeps him rooted to the spot.

Cassy is amazed to see Martin actually taking his shirt off. Well - what an interesting day this is turning out to be!

Martin stands awkwardly with no top on, feeling cornered by the schoolgirls and teacher. She looks him up and down and consults the textbook, oblivious to his feelings.

She points to one of his nipples with her pencil and he can feel the sharp tip brushing against his skin.

"You can see that men too have nipples," she explains. Martin looks at Veronica and the others who are completely wrapped up in what the teacher is saying.

"What purpose do they have for men?" She asks, "why do you think boys have nipples?"

Cassy pipes up eagerly, "for milk Miss?"

"Good guess Cassy,' praises Miss Marchmont, "In a way yes, they are for milk."

"All humans start off as male in the womb," she explains, "and later continue to develop to become female if they are to be female beings. In a sense all males are a simpler form of life."

The girls murmur in agreement - it makes complete sense to them and confirms what they have always suspected.

"That leaves men with nipples which have no function. However, they are still vital as can be seen when they are touched." Martin shifts nervously not liking the sound of that.

He winces as she leans forward and grips his sensitive nipples in her fingers, twisting them sharply. The girls start giggling again - enjoying the look of pain on the young man's face.

The female teacher's proximity makes him feel all the more uncomfortable. She pinches him hard and he almost cries out in shock. This is awful!

"You see how they become hard and erect with just a little stimulation." The girls all nod. "Now this is to be a 'hands on' demonstration - so please line up and each of you can have a go with him." Martin nearly faints with shock. Oh no! This terrible woman has just given the girls permission to touch him! Being alone in a room with the school nurse suddenly doesn't seem so bad after all...

A bewildered Martin Simpson stands surrounded by girls in the Biology class. It certainly wasn't what he was expecting from the physical exam. But the new teacher Miss Marchmont is insistent that he take his top off and allow the girls to explore his body. In the corridor the other boys wait uncomfortably to be called by the nurse - unaware of their friends plight. It seems with everything going on that there has been some sort of mix-up at St Dunstan's.

Martin is terrified of being touched by the girls and cannot believe that Miss Marchmont is actively encouraging it. Surely his physical should be conducted by a qualified nurse?

Tanya goes first and stands right in front of him, staring at his naked torso with interest. Her closeness makes him uncomfortable and he tries to edge away.

But she has him pinned up against the blackboard and grabs hold of his nipples, twisting them hard. Martin winces as the sharp pain shoots through his chest.

"Go on, have a go. It's fun!" She says to Dawn, giving her an encouraging shove towards him.

Dawn stares him right in the face and sneers - she's going to enjoy this!

She pinches his nipples hard, pulling on them - her look daring him to try and resist. But he's too intimidated by the new teacher to risk upsetting her.

She shrieks with delight as he grunts with pain. Veronica looks over her shoulder impatiently waiting for her turn.

She sidles up to him, taking her time to evaluate his athletic physique. She doesn't really care why men have nipples, but she's more than happy to have a play around with them.

Looking at him lustfully she reaches forward and grasps his sensitive nipples between her thumb and finger.

She manipulates them more gently than Dawn and Tanya which is even more disturbing for poor Martin. Strange new feelings stir inside him and he feels his penis twitch inside his underpants. "My turn!" Calls Cassy - interrupting her friend.

She rushes over not wanting to be left out and keen to show Miss Marchmont what a diligent student she is. She takes hold of his nipples one at a time, studying them closely.

This is certainly a lot more interesting than their normal Biology lessons! She's sure she's going to learn a whole lot more about the male anatomy today.

Martin stands there uncomfortably, unable to do anything about the repeated stimulation of his nipples. He can't work out how this is supposed to check his physical health but the teacher must know what she's doing.

Cassy seems to be taking her time over her exploration of Martin's body and he gulps nervously. "Right!" Interjects Miss Marchmont, "Now you've seen male nipples we can move on to the rest of his body!"

Paul Williams walks up the stairs clutching his interview letter, lost in the vast network of corridors in St Dunstan's. He sees a group of young men sat in a row with sports bags to their sides.

'Ah!,' he thinks to himself, reading the sign above their heads. 'These must be where the applicants for the physical education job are to wait.'

They all look very young. They must be just out of college like him. "Excuse me mate," he says to Logan, "are you here for the..." he waves the letter about, "is it being held in there?"

Logan nods, unsure who this stranger is. He looks bigger than the rest of them - he must be from the year above. He's too worried about his own impending physical to give it much thought.

"Is this seat free?" Asks Paul and when the young lad nods again he sits down nervously. He wasn't expecting so much competition. He decides he'll have to work extra hard to create a good impression.

No sooner has he sat down than Nurse Bleifrei comes bustling out of her room making them all jump.

She notices the young man sat in the previously empty seat. "Oh there you are!" She says - glad that she can get started at last.

She sees the others haven't followed her earlier instructions. "What have I said?" The boys remain silent. "You're not going to get anywhere until you've had your physical exams first. Now strip down to your pants."

"Erm?" Says Paul wondering what's going on. He wonders if it's part of the interview process.

"Yes?" says the nurse, crossing her arms and staring at him. She's already had to wait for him to turn up, she's not going to put up with any more of his delaying tactics. "I didn't know there'd be a physical exam first," he mumbles meekly.

"Of course you did," she responds abruptly, "This is St Dunstan's school. Everyone must be fit and healthy! Now down to your pants."

She turns to the others. "Put your clothes under your chairs." Paul's not comfortable with the idea of having to strip - especially in front of the other interviewees. But he guesses his chances of getting the job will be zero if he refuses.

Logan, Vincent and Aiden stand up aware that they'll get into serious trouble if the nurse reports them to the headmistress. Nervously they begin to undress.

Following their lead Paul stands up, looking down the line as the others fumble with their belts. 'Oh well, I'd better not be the last one,' he thinks to himself.

The nurse looks down the line to make sure no-one gets up to any funny business. The boys are all aware of her watching their every move and it makes them all even more uncomfortable.

She's determined that they won't disobey her again and urges them to hurry up so she can get started.

Paul loosens his tie. He was totally unprepared for anything like this and it's totally thrown him. But jobs at St Dunstan's are highly sought after and he can't risk looking bad in front of the nurse.

Vincent is the first to strip down to his underpants and stands awkwardly, covering his crotch and staring at the nurse - who watches them like a hawk.

He sits down while the others struggle to remove their trousers in the confined space. The nurse tuts - why is this taking so long?

Paul is aware that he's the last to get down to his underwear and feels everyone staring at him. He knows he's got off on the wrong foot with the imperious nurse and hopes it won't adversely affect his chances.

Finally all the young men are sat in a row. Paul looks across at the others and sees they are all wearing childish underpants with cartoons on and bright colours. They look like something bought by their mums!

They obviously weren't prepared for the physicals either and he's glad he opted to wear Emporio Armani. A lot more sophisticated and definitely sends out the right signals.

He looks up at the nurse, his confidence bolstered. "You won't find anything wrong with me," he says - eager to impress.

"I should hope not!" Replies Nurse Bleifrei, "But I'm going to check anyway. You're first. Leave your things and follow me."

Not sure if going first is a good or a bad thing, Paul jumps up and follows her as she enters the room.

He takes a deep breath. A lot is riding on this and he must do whatever it takes to get this job.

Outside the school gates a sports car pulls up and a man in a tracksuit gets out. He locks it behind him and gets out a letter from his bag.

Paolo Di Silva doesn't understand English very well, but he can see that it says he should be at the school for 10am. It's already 10:30 - he's late.

He shrugs and sets off. It won't hurt them to wait for the great Paolo Di Silva! It'll ensure they are all the more excited when he turns up.

"Come in, come in," beckons the nurse as Paul stands uncertainly in the doorway.

"Sit on the edge of the couch," she instructs and Paul does as he's told. The nurse moves a screen across the door to give them privacy.

"You're very hairy for an 18 year-old," she observes - looking him up and down.

Paul assumes she must be making a joke. "Oh I'm quite a bit older than that!" He says with a chuckle.

"Oh yes?" says Nurse Bleifrei. Great - a joker - that's all she needs. "You must be very proud of your chest hair. Now then, let's get started."

She picks up her stethoscope from the table and walks towards Paul. He's always felt uneasy at the doctor's and hopes that he won't have to spend very long in the tiny room.

"Let's have a listen to your heart shall we?" She says, pressing the device to his chest.

She leans in close and Paul is intensely aware of her proximity to him. He breathes out slowly, trying to calm himself.

"Your heartbeat is very fast," she says to him. He gulps, worried that she'll guess that she's the cause.

"Oh it's just nerves you know," he replies, trying to make light of it. "I really want to do well in this. I've always wanted to do this." She looks at him quizzically.

Well, this is definitely a first. A young man who actually wants to undergo a physical! She takes a note of his results in her pad.

"Now then, your height. Over here please," she says briskly.

He follows her to the corner. "Height?" He questions, "Oh I see. You want me to be the tallest in class. Command authority. I understand."

"Ho ho," she says in a condescending tone. "We have to make sure you're fully developed."

"I'm certainly that nurse!" Says Paul, seeing an opportunity to try and impress her. "I'm a striker. In football! it's on my CV. I've played for the county."

"Really," she replies sounding disinterested, "that should go in the school magazine." With so much to get done she doesn't have time to listen to the boys' stories.

Paul is proud of himself, her suggestion must mean that he's close to getting the job! "Yes," he says enthusiastically.

"Now for your weight," continues Nurse Bleifrei fearing that they'll be here all day if she allows him to witter on.

She marches over to him and grabs hold of his underpants. "What the?" Says Paul in alarm.

Before he can react she whips them down. "We won't get an accurate measurement with these on will we," she says.

"Oh! But!" He tries to think of something to say but she moves too quickly and his thick penis and heavy testicles come bouncing out into view.

In a matter of seconds she has his underpants off leaving him stark naked.

Terrified and wondering what is going on Paul covers himself up. He looks fearfully at the woman stood right in front of him as she steps towards him. Just what kind of a job interview is this?

Martin stands petrified with his female classmates surrounding him. Not daring to question the teacher's authority he accepts this must be a particularly unpleasant form of physical exam. The girls are just thrilled at having a live male model to liven up their boring lesson. But it's not just Martin and Paul who are in for a surprise today. The headmistress waits impatiently for her interviewee to turn up, blissfully unaware that the man about to arrive is here for another purpose entirely.

Miss Marchmont grabs Martin by the chin and jerks his head up. As far as she's concerned, as the school is paying for this life model she can be as rough as she likes.

"Men's faces develop for longer from the age of fourteen onwards," she says regarding him dispassionately.

"Female faces stay beautiful while men's faces continue to grow, becoming harsher and more angular. See?"

The girls can't wait to inspect for themselves and crowd around Martin. Veronica and Cassy start touching the skin on his face, pulling it about.

Soon the others join in, feeling for themselves. Martin feels uncomfortable being grabbed like this and wonders again just how this helps to assess his physical health.

The girls encourage each other, pinching him and running their hands along his jaw line.

"Males have rougher skins. See?" Says Miss Marchmont, encouraging them to continue their exploration of Martin's body.

Veronica and Tanya are fascinated. They've never had such free access to a boy before. It's wonderful to think that he's there just for them to study and play with.

Their hands wander down his exposed torso, feeling the roughness of his skin - just as the teacher had described.

Martin tries to shrink away from their groping hands but Cassy stands behind him keeping him in his place. She suspects there has been some sort of mix-up but she's not going to risk spoiling their fun by saying anything.

Miss Marchmont continues the lesson: "Now girls. Males have a hormone called testosterone." The girls listen attentively.

"It makes the muscles grow bigger." She grabs Martin's upper arm and instructs him to flex his biceps.

"See? Look at these." Martin does as he's told, standing there awkwardly as the girls squeeze his arm.

It feels belittling to be touched up and evaluated like this, as though his feelings were irrelevant.

Miss Marchmont is pleased to see her girls so engaged. The model isn't quite what she was expecting, but the main thing is that the students get a good education.

"Why do boys need to have bigger muscles Miss?" Asks an interested Cassy.

"If boys didn't have big muscles to do manual work, there wouldn't be much use for them now would there?" She looks at Martin as though he were an inferior being.

The girls all laugh and agree straight away. It makes perfect sense to them.

"Where does testosterone come from Miss?" Cassy is really getting into this lesson and is keen to keep impressing the new teacher.

"That's a very good question. It's made in the testes. The testicles." Martin looks at the fierce woman with fear, not liking the direction this is going.

Miss Marchmont looks down at his crotch. "Show the girls," she says matter-of-factly.

Martin freezes with shock. What did she just say? The room goes completely silent and it feels to the young lad as though time has stood still. Everyone looks at him expectantly.

The girls exchange astonished glances, wondering if shy little Martin will actually do it.

Miss Marchmont addresses him like she's asking something really commonplace, an edge to her voice. "Take your trousers down and show your testicles to the girls."

Martin is horrified. Is she seriously saying that he has to get his privates out and show them to the girls?

Getting more and more impatient, the teacher tries again - speaking slowly as he seems to be having trouble understanding her simple instructions. "Take your trousers down so all the schoolgirls can examine your genitals!"

Paulo Di Silva has made it to the school. The money from this modelling job will come in handy with his extravagant lifestyle.

Most of the letter he clutches in his hand is unintelligible to him. But he sees the word headmistress on a door and recognises it from the top of the letter. Assuming he must be at the right place he knocks firmly on the door and hearing a voice say "come" he opens it and enters.

The headmistress has her phone in her hand but turns as the tall man strides into the room. "Good morning. Paul?" She enquires.

"I have come for the job," says Paulo utilising what little English he has learnt. In his profession speaking isn't that big a requirement.

The headmistress notices his sports bag and tracksuit. 'Well he looks the part at least,' she thinks to herself. "You are rather late. I was just about to call you," she admonishes.

She puts the phone down and looks him up and down. Quite a fine physical specimen. He bounds forward and offers her his hand. "Paulo," he introduces himself.

"Paulo?" Questions the headmistress, flattered by his good looks. "Oh. I thought it was Paul. Where are you from?"

"Ah Brazil. I from Brazil! Where should I stand?"

'That explains it,' thinks the woman to herself. "Oh please, sit down," she gestures towards a chair.

"Si, si, I sit!" Says Paulo eagerly, "When do you want me to start?" Normally by now he'd have his clothes off and be performing for his audience.

"That's a bit presumptuous Paulo if I may say. I have a lot of questions to ask you."

"Si," he replies - trying to work out what she's saying to him.

"So what's your background? What have you done?" Paulo is certainly less formal than she's used to, but she's quite taken with him.

He looks bewildered and she realises he hasn't understood her. She looks at his CV on her desk. "I see that you've played football for your city?"

Recognising the word football he suddenly becomes animated. "Si, si, Sao Paolo... I also Sunny Beach swim-boy 2010 and 2011. You know in the sunshine, fashion, dancing, speedo... Lots of lovely ladies you know?"

"The cocktails, the cameras, click click!" He gets excited as he continues, "I appear on Channel 13 Sunny Beach Nature Show Sexy Sexy. I very big boy, very big. No cut off."

The headmistress is a little confused by his heavy accent, but managed to catch certain words. "Ladies? I see. So you have taught young ladies in the past. Good. What about boys?"

Once again a look of confusions crosses his face. "We are a mixed school," she explains, "Do you have any experience with boys?" She chuckles to herself, "They can be quite a handful!"

"Boys? Boys? Ah Si Si, yes yes - I do Mardi Gras. Very happy. All ze boys love me. Yes yes. I do both, I do both, yes!"

"Good," says the headmistress, pleased. "Now what about discipline? I have to tell you we put a lot of store by discipline." She notices the St Christopher hanging around his neck. "I see you are a man of faith which is very reassuring."

"Discipline? Discipline? Ah yes I know this. Yes, spanky spanky!" He laughs then notices the cane in the corner.

"I see. Ha ha! you very naughty lady, ha ha. You tie the hands yes and then you spanky spanky. Very good. I like. I like!"

Understanding only a little of what he just said, she cannot help but laugh. "Oh we don't tie hands in this country I'm afraid. But if a pupil steps out of line I do believe in discipline."

She turns back to his CV. "I see: cricket, tennis, football, rugby. You're very accomplished at team sports." Mistaking his blank look for lack of comprehension she tries another approach. "Sport involving balls?" She queries.

"Bolls?" He questions uncertainly. Fumbling to find the right word the headmistress tries again. "Balloons, erm, bolas?"

"Bolas! Si si, bolas. I show you?" They are finally moving into territory that Paolo understands.

He drops his bag to the floor and grabs his crotch.

The headmistress gets exasperated but decides that perhaps a demonstration will be more productive that a verbal interview. "Hmm, well yes - perhaps if you show me your sporting skills... Yes go on then."

Paolo goes rummaging in his bag and starts pulling things out of it.

The headmistress is totally confused. There appears to be a Brazilian flag and a can of whipped cream on her desk?

Next he pulls out a bottle of baby oil and finally a CD player. Just what kind of sporting prowess is he going to show her?

Back in the Biology room, an impatient Miss Marchmont has decided she can't wait any longer for the model to undress and reaches for Martin's belt.

The girls are in fits of laughter as she unbuckles it. Martin looks like he's about to throw up! They wait to see if he'll put up any resistance.

Moments later and his trousers slip to the floor. The girls all gasp - it looks like the new teacher is actually going to strip him right in front of them!

The girls try and stifle their giggles as Miss Marchmont pulls them off. Martin starts to shake with fear. Please don't let her go any further!

But almost immediately she grabs the waistband of his underwear. Instinctively he grabs hold of them himself to prevent her from pulling them down.

He's almost in tears, the thought of being naked around all these girls unbearable.

Feeling his resistance Miss Marchmont looks up at him sharply. "For goodness sake! You knew this is what you had to do today."

"I know. But I didn't think it would be in front of anyone," he moans.

"Of course you did you silly man!" She tugs with all her might but Martin holds on tight. "Let go right this minute," She shouts.

Terrified of her he relaxes his grip and she starts to slide his underpants down.

In one quick movement she yanks them down and Martin's genitals come tumbling out into view.

The girls shriek with delight. They cannot believe it! Martin Simpson stark naked in front of them! He penis finally settles down and the girls stare at it openly.

Martin sobs wretchedly. This is his worst nightmare. He can feel the girls all staring intently at his exposed privates and he cringes with embarrassment. Miss Marchmont isn't at all impressed by his behaviour. She's determined to get her money's worth out of this young man - one way or another.

It seems nothing can go right today at St Dunstan's. While a terrified Martin has been stripped totally naked by the Biology teacher, Paul Williams (who thought he was here for a job interview) is being examined by the school nurse. The headmistress is a little bemused by the candidate she is interviewing - who's lack of English is only adding to the confusion. But Hunky Paulo has a few tricks up his sleeve that he's sure will impress the stone-faced woman.

Having unloaded a few props from his bag, Paulo starts pressing the buttons on his CD player. The headmistress cannot fathom what is going on. It's the strangest job interview she's ever conducted!

Suddenly music starts booming out of the portable music system making the woman jump with surprise.

Before she can say anything he grabs hold of her chair and pulls her towards him. She lets out a startled yell.

But he merely grins at her thinking she's playing along with him.

He wheels her to where there is more space and stands before her. "What on earth?" She questions - but her words are drowned out by the music.

He starts gyrating in front of her - spinning around and waving his backside in her face. She shrinks away from him but is trapped.

His jiggling buttocks are inches from her and she screws her face up in shock.

'What is going on?' She thinks to herself. 'What has this got to do with showing me his sporting prowess?'

He turns around to face her and starts to pull up his tracksuit top. "Oh my!" She exclaims - but he ignores her and carries on with his routine.

"I see you like!" Says Paulo - not at all discouraged by the look of consternation on her face.

He whips the top off while the dazed woman wonders where this is all leading.

He spins the jacket around his head. "Mr Williams please!" She shouts above the din, "I think there has been a misunderstanding."

"Ah no, I understand very well pretty lady," he says, waggling his finger at her as though she had done something naughty, "There are no girls here today. You say in letter I perform for group of girls - but is only for you no?!"

He tosses the garment to one side and makes to take off his t-shirt. The headmistress is aghast. What is he going on about? Her letter was very specific - he was to attend an interview for the position of PE teacher. No mention was made of any performance.

She covers her face modestly as he pulls his t-shirt over his head, but cannot help but peek through her fingers.

'Well really,' she thinks to herself, 'this is no way for an interviewee to behave. He's definitely most unsuitable for the role.'

'Although...' She looks up at the big man towering over her. 'He does at least look very sporty.'

He reaches past her and grabs the bottle of baby oil from her desk.

She watches in alarm as he starts pouring it down over his chest, shying away in case any of it gets on her clothing.

All the while his body rocks to the beat from the music system. Paulo is in his element - he knows just how to turn the ladies on.

Rubbing the oil over himself he speaks to the headmistress, "I am very muscley boy yes?"

He smiles at her, his body glistening from the oil.

"Well yes Mr Williams very muscular. I can't fault you on that. No." She wonders if perhaps she was too rash in making her decision. The other female members of staff would undoubtedly appreciate his well-honed physique.

"Closer!" Says Paulo, straddling her. "I really don't think..." She exclaims but before she can object, he grabs hold of her...

...and thrusts her face right into his chest, enveloping her.

He rubs her face all over his oily body. He can tell from the muffled little moaning sounds she makes that she's enjoying it. Ah yes indeed - Paulo Di Silva knows just what women want!

In the Biology room Martin can still hear the girls laughter as he stands totally naked before them all. He quickly covers himself up despite the frown on the teacher's face.

He's horribly embarrassed. He tries his hardest not to cry but cannot help letting out a sob. He had no idea that physical examinations were conducted in front of everyone like this. If he'd have known there's no way he'd have come into school today.

"Oh no!" Calls Miss Marchmont harshly, "You are here to show your private parts to the girls and that is what is going to happen!" She's had enough of this young man's nonsense.

The girls can't very well examine his genitals with his hands in the way can they? She raises her hand in the air...

...and brings it down smartly against his covered crotch with a loud slap. The girls burst into renewed fits of laughter.

Having no choice Martin reluctantly parts his hands, revealing his penis and testicles. He stands there petrified with his hands by his side. "Put them behind your back," instructs the fearsome woman.

He does as he is told, intimidated by Miss Marchmont's stern tone. He'd give anything not to be here exposed like this but what else can he do? Her authority is absolute and he daren't disobey her.

"Now then girls," says the teacher, keen to get on with the lesson.

Martin is painfully aware that his private parts are being scrutinised by the assembled girls. These are his classmates - people he see's every day. How is he going to face them from now on knowing that they've seen his most intimate parts?

"Can you see these? Move in close to get a better view." The girls don't need telling twice and huddle in.

Their very proximity increases his nervousness. He's harboured private fantasies about all of them at one time or another and he's very uncomfortable with them being so close to his penis.

"This is called a PENIS," explains Miss Marchmont, picking up Martin's penis to show it to the girls as though it were nothing special.

"And these are called TESTICLES." She lightly cups his testicles in her other hand. The girls all stare in wonder.

She pulls his penis sharply to one side so they can see his testicles more clearly. It feels wrong to have his bits and pieces manhandled by the teacher like this.

The girls are enthralled by the confident way the teacher manipulates Martin's genitals. She does so totally without concern for his feelings. 'After all,' she thinks, 'he's a paid model - he should be used to this.'

Dawn feverishly writes down Miss Marhmont's words - the others will copy her notes later in the lesson. Biology has never been such fun before!

They all lean in close as the teacher pulls his penis this way and that so they can see it from all angles. Martin whimpers with the shame at having his private parts displayed to the girls like this.

The female students gasp with delight and Martin can feel their warm breath on his exposed skin, making him come out in goose-bumps.

Miss Marchmont squeezes his scrotum in her hand so his testicles are more prominent. "These produce the hormone testosterone which makes boys develop into men. Can anyone tell me what else they produce?" The girls all look thoughtful.

Cassy raises her hand, "is it sperm Miss?"

"Yes, well done Cassy." Miss Marchmont is pleased to see her new pupils are familiar with the male reproductive system.

"When a boy reaches puberty he begins to produce sperm in a fluid called semen," she continues. "Now can anyone think why the testicles are on the outside of the body?"

The girls all think hard. "Erm..." Says Veronica, wanting to be as good at Biology as Cassy - but none of them have a clue.

"Hanging freely," says Miss Marchmont encouragingly, "dangling..."

She uses her pencil to flick Martin's testicles to make them swing and jump about.

They bounce around eliciting yet more giggles from the girls. Her actions cause a strange sensation in Martin's groin - and not a pleasant one.

He winces as she pokes and prods his sensitive scrotum, waiting for the girls to work it out.

Suddenly Veronica pipes up, "Is it so they can be grabbed hold of by girls if boys don't do what girls want?"

The girls all laugh loudly at her suggestion, as does Miss Marchmont. Martin is horrified at the thought and looks like he's going to be physically sick.

"It's a good idea," says the teacher, impressed by the girl's initiative, "but seriously it's to keep the semen at a lower temperature to the rest of the body."

"Like a fridge Miss?" Questions Tanya - more enthusiastic than she's ever been at school before.

"Yes, just like a fridge," she replies. "The semen can build up and up and up over many weeks and be stored in this sack, which is called? Does anyone know?"

The girls think for a minute then all speak in unison "A scrotum?"

"A scrotum yes. Because it's cooler in the scrotum sperm can keep fresh for weeks and weeks and weeks."

"Now I want you to each hold the scrotum and see that it's quite a bit cooler than the body temperature." The girls all look up at Martin, wondering how he'll react and knowing that the shy young lad will hate to be touched by them all.

As her words sink in a look of horror crosses his face. No. Not that. Anything but that! She can't seriously be suggesting that each and every one of the girls in the room takes hold of his testicles and feels them? But Martin has a horrible feeling that's exactly what she intends.

Martin is utterly petrified. He cannot understand what is going on. It seems totally wrong to him that his physical examination should be conducted by his female classmates. But the fierce woman in charge scares him so much that he daren't speak out. Now she's invited the girls to take hold of Martin's scrotum for themselves and he suddenly realises he has even more to worry about.

"Cassy, you go first," says Miss Marchmont to the excited girl. Martin nearly makes a run for it but she still has his testicles in her hand.

Cassy moves round and stands directly in front of Martin, looking down at his genitals. Ignoring his whimper she reaches for his privates.

She looks up, staring him full in the face and smiling. She's going to enjoy handling Martin - especially given the look of fear on his face.

She cups his balls in her hand causing him to gulp. It was bad enough having the teacher manipulate his penis and testicles, but it's a whole lot worse when it's one of the girls he sees every day.

"There, you see?" Asks the teacher, pleased to see her pupil taking a firm grip on Martin's scrotum.

"Yes Miss," replies Cassy. The others lean in to get a closer look, jostling each other to get the best view and all eagerly waiting for their turn.

She turns to her friend. "Go on Veronica, you have a turn." Veronica can't wait - she is transfixed by Martin's exposed privates and rushes to take her place.

Like Cassy she notices the look of horror on his face. It's such a treat for her to be given full permission to touch Martin like this and she relishes the moment.

Martin can feel her fingers on his genitals as she sliders her hand around his testicles. He's utterly helpless to stop her but alarmed at the thought of springing an erection in front of the class.

He tries his hardest to ignore her delicate touch but already strange feelings are building up deep inside him.

She seems to be taking an age to feel the temperature of his scrotum and every second his balls are in her hand he finds himself becoming more aroused.

She looks up at him, realising that her actions are driving him wild. It's a huge power-trip having so much control over a boy like this.

She can't help herself and bursts out laughing and the other girls join in. Dawn starts to get impatient and hops from one foot to the other. "My turn, my turn!" She calls out.

She approaches the quivering Martin, savouring the moment. His penis and testicles are dangling there invitingly in front of her.

She lets out a gasp as she takes them in her hand. His scrotum does indeed feel cooler than the rest of his body.

Like Veronica, she takes her time to explore his private parts with her hand. She jiggles his testicles about causing Martin's arousal to increase.

"Ugh - they just twitched in my hand!" She shrieks and pulls her hand away.

Realising what's happening to the boy she laughs right in Martin's face. "I wonder if I can make it happen again?"

She grabs hold of him again with renewed vigour, squeezing and pulling on his scrotum. Martin groans inwardly. It's taking every bit of his willpower not to get hard but the girls seem determined to make him embarrass himself in front of them.

It's time for Tanya's turn and she can't wait. She looks at him like a wildcat evaluating its prey. She knows he can't run from her and she can take as long as she wants feeling him up.

"Go on!" Encourages Cassy as Tanya reaches between Martin's legs.

Martin is disturbed by the confident way she takes him in hand. She seems to be more forward than the other girls and the glint in her eye sends shivers down his spine.

Against his will his penis starts to respond. "Ooh, I think something is happening down here," says Tanya.

Almost in tears he tries desperately to restrain himself. But the girl seems to be deliberately trying to stimulate him with the way she manhandles his privates.

The others gasp as they see Martin's penis getting bigger before their eyes. Tanya tightens her grip on his testicles eliciting a small moan from him.

Well, well, well - little Martin Simpson isn't so little after all! Wait till they tell the rest of the school what he did in their Biology lesson.

Tanya takes his rapidly thickening member in her hand. It feels silky smooth yet hard at the same time. Martin swallows, everything she does seems to get him more aroused.

She lets go and his penis bobs up and down under its own weight. There's no hiding it - Martin has got a stonking erection right in front of the whole class.

Miss Marchmont notices something strange out of the corner of her eye and turns her head.

A look of disgust crosses her face when she sees what's happened. "Good grief!" She bellows

"Really! I thought you were professional. Does this happen whenever you go to a school?" She eyes his throbbing penis with distaste.

Martin his horribly embarrassed. "Yes," he says in a small voice, "it happens lots of times Miss. I can't help it."

"I shall be having words," says the teacher threateningly and Martin can only wonder at how much trouble he's in.

"Miss, why is his thing doing that?" Asks Veronica all sweetness and light.

"Yes Miss, look," says Tanya and bats his penis to one side.

It whacks against him causing a shooting pain that makes him grunt.

Eventually it settles back down but is still fully erect.

"This girls, is an erection. And if you ever encounter a boy with one of these run in the opposite direction!"

"When boys are having filthy thoughts their penis becomes hard and sticks out most stupidly like this. It's a warning to girls to beware," continues the teacher. Feeling bold, Veronica grabs hold of it and examines it closely.

Following her example the other girls pounce on poor Martin's exposed genitals - touching, prodding, pushing and pulling them about.

He's intensely aware of their fingers caressing his engorged manhood, teasing him and making his balls churn.

He watches helplessly as they toy freely with his penis and testicles. He wishes the teacher would say something; stop them from touching him before it's too late. But Miss Marchmont is pleased to see them taking such a close interest in Biology and lets them get on with it.

"You see," she says by way of an explanation, "nasty thoughts have made his heart beat faster and fill his penis with fluid."

"All a man can think about when his penis is like this," she swats his penis to emphasise her point...

..."Is making it shoot sticky hot white fluid out of it." Even the sharp pain isn't enough to counter the feelings building up and threatening to overwhelm him.

She stands up suddenly and moves in close, staring him straight in the face accusingly. He whimpers with fear.

"Into a lady. He can think of nothing else," she concludes menacingly. Martin is petrified - It's as though she can read his mind.

She turns away to answer one of Tanya's questions and something erupts deep inside him. Veronica and the other girls notice something strange is happening.

They lean forward just as a blob of white stuff appears at the tip of Martin's penis.

Unable to hold back any longer, Martin lets out a stifled moan as a jet of sperm fires out of him.

He bites his lip trying not to make a noise as the orgasm takes over. Cassy bursts out laughing again - this is just too funny!

"What, like this Miss?" says Cassy, pointing at Martin's penis as he ejaculates.

Miss Marchmont looks round and is aghast at the sight that greets her: the male model standing there with semen coming out of his penis right in front of the girls.

She watches with fury as a thick strand of the stuff hangs from the end of his member before dropping to the floor...

...making a sticky pool at their feet.

Martin is utterly mortified. He cannot believe he has just ejaculated in front of his classmates! He'll never live this down as long as he lives. And the teacher looks incandescent with rage. He quakes with fear at what she'll do now he has shamed himself like this.

Martin Simpson has just embarrassed himself by ejaculating in front of the girls and teacher in the Biology lesson. But he's not the only one placed in an uncomfortable position - Paul Williams has just been stripped completely naked by the school nurse. Under the impression that this is part of his job interview, the nervous young man feels under pressure to go along with her every instruction. But as the examination progresses he becomes increasingly nervous.

Martin stands there horribly ashamed at what he's just done, the last dribbles of semen dripping from the end of his penis. The girls are fascinated by just how much of the stuff he's produced. But Miss Marchmont is less impressed. The furious woman decides it's about time this model was punished for his appalling actions.

Back in the infirmary things are just as confused. "OK, over here and up on the scales so we can weigh you," says the nurse brusquely. Paul dithers uncertainly with his hands covering his genitals. But he really wants this job and realises he has no choice but to obey her.

He shuffles round to the weighing scales trying to keep himself covered up. He thinks about the lads sat waiting in the corridor who he assumes are other candidates. He imagines them listening in and feels even more embarrassed.

Hesitantly he places one foot on the scales totally unnerved by being naked and defenceless like this. "Get a move on!" Says Nurse Bleifrei impatiently.

Obediently he does as he's told. "That's better. Now then..." she peers are the display but can't make out the reading.

She bends forward and Paul has to suppress a gasp as he looks down and see's her face so close to his privates.

Her hair brushes against his hand and he can feel her breath on his legs as she mutters to herself. He gulps and his penis twitches against his fingers.

She stands up abruptly having recorded his weight. "Good," she says, "now step down and place your hands behind your back."

Paul reluctantly parts his hands and his penis and testicles once again come into view. He pauses wondering if perhaps he misunderstood her. "Behind my back?" He questions and the nurse replies, "yes of course!"

He feels awkward standing there with everything hanging out while the nurse busies herself with something on the trolley.

He wishes the woman would let him put his underpants back on but she seems to want to continue with him completely naked regardless of his discomfort.

"I must say this is more thorough than I was expecting," he says weakly, his face reddening.

"We're always thorough at St Dunstan's," she says in a weary tone as though he should already know this.

She reaches down and without warning takes his penis and testicles in her hand. Paul looks away in shock. He certainly wasn't expecting that!

He grits his teeth as she feels all around his gooch area trying desperately not to get aroused in front of her. That would totally ruin his chances at getting the job.

But it's very hard not to react as she proceeds to roll his foreskin back and forth and squeezes his testicles. "Cough," orders the nurse, interrupting his train of thought.

He does as he's told and she tugs on his testicles. He has no idea what she's learning from all this but he wishes desperately that she would stop. He's not sure how much longer he can restrain himself.

"And again," she instructs, looking him full in the face.

He turns to one side and coughs again hoping that she'll release her grip soon.

His penis is already thickening from the unwanted ministrations of Nurse Bleifrei and he expects her to realise any second and tell him off.

But she doesn't seem to have noticed and abruptly lets go of his penis which flops down heavily.

"Now," she says ominously, "bend over the desk and pull your buttocks apart."

Paul is sure he must have misheard - it sounded like she just asked him to bend over and pull his arse cheeks apart. Surely not? His unease increases and he starts to feel sick.

"Come along now, what are you waiting for? Over there!" Very warily a confused Paul makes his way to where the nurse has indicated.

Nurse Bleifrie follows. This one seems to be a bit slow. She'll have to make sure she's very clear with her instructions to him.

He pauses in front of the desk. "That's right," she says encouragingly, "All the way over and grab hold of your buttocks."

Even though it feels wrong he does as he's told. "Now we can continue," says the woman and Paul's heart sinks.

Back in the headmistresses room, the interview isn't going according to plan. Her interviewee seems to be some sort of madman who presses her face tight against his oiled torso.

Finally she manages to pull away, spluttering and gasping for air, her face and glasses covered in baby oil.

She reaches for a tissue to wipe the oil off. Unperturbed, Paulo continues with his routine - gyrating in front of her and occasionally letting out a whoop.

'Now is time to hot things up,' thinks Paulo to himself and starts to slide his tracksuit bottoms down.

Barely able to see, the headmistress desperately tries to get the messy oil off her skin and clean her glasses.

Paulo looks round at her. Oh yes indeed - she is in for a treat now! He'll loosen this uptight woman up.

He bends over and starts wiggling his bottom in her direction, his buttocks inches from her face.

Noticing something out of the corner of her eye, the woman looks round and is stunned to see his behind so close to her - the thong pulled right up the crack and leaving little to the imagination.

It all becomes too much for her and she lets out a bloodcurdling scream. "Aaaaaarrrrgghhhh!!!"

But Paulo isn't put off in the slightest. He's used to women screaming at him with lust and is pleased that he's finally getting a reaction from her. He thrusts his bottom even closer and she shrinks back as far away from it as she can get.

He accidentally steps heavily on the bottom of her chair causing it to tip forward and fling her face first into his backside. 'Ah - the cheeky lady she like,' he thinks, taking it as encouragement.

She pulls away and adjusts her glasses. Nothing like this has ever happened to her before in her entire life!

Normally used to being in total control she doesn't know how to react. He never stops moving, swinging his hips seductively in time to the blaring music.

He grabs hold of her hands and although she tries to resist, he is too strong for her.

He places her hands on his round oiled buttocks and presses them there firmly. She can feel the muscles under the skin tensing.

She looks away in disgust. This can't be happening! Just what does all this have to do with being able to teach schoolchildren PE?

He lets go of her hands and she immediately pulls them away. He reaches past for the bottle of baby oil and begins pouring it liberally down his back.

She watches in horror as it cascades down and dribbles down the crack of his arse, much of it ending up on her dress.

He takes her hands again and rubs them against his buttocks all the while making sounds of appreciation. "Ooh yeah - that feels good!"

"NO!," Pleads the headmistress, "No, no, no, no." But Paulo ignores her pleas.

Unable to take any more she starts to cry but even this doesn't put the big Brazilian man off. Paulo has a routine to do and he intends to see it through - all the way to the end.

"Please Paulo, no more," she begs, "I don't think you are really suitable for this job."

He looks around at her. He doesn't have a clue what she's saying but he knows just what she needs.

He turns to face her and adjusts his posing pouch.

She shrieks as he brings his groin close to her face. "AAAAAAARRRRRRGGGHHHHH!"

She's stunned into silence by the huge bulge that is barely contained by the tiny piece of fabric covering his modesty.

Holding her head in place he thrusts his groin back and forth, hitting her in the face with his pouch.

She finds her voice again and screams at the top of her lungs but this just seems to encourage him.

Stepping out of his tracksuit bottoms he lifts his leg up onto the back of her chair bringing his groin even closer. She's trapped, pinned in her seat by the excitable foreigner.

She whimpers in anticipation of what he'll do next.

She doesn't have to wait long as he grabs her head and presses her face right into his bulge. "Hrmpf," all she can manage is a muffled cry of protest.

"You like big Brazilian boy yes? I know. I know." Paulo is oblivious to the look of distaste on her face.

She makes her mind up that next time she'll leave the interviewing to her deputy. "Yes. I have extra special BIG surprise for you lady," he says to the distraught headmistress. She looks up at the glint in his eye and realises that her ordeal isn't yet over.

The headmistress is having a very distressing time of it. Her interviewee is certainly very sporty looking, but his poor grasp of English has clearly led to some confusion. When she asked him to demonstrate his abilities she certainly wasn't expecting him to start stripping in front of her! Overwhelmed by the enthusiastic Brazilian she just hopes he'll stop before things go too far.

The befuddled woman cannot work out what's going on. The oiled-up man keeps wiggling about in front of her and seems oblivious to her whimpers of fright.

He leans in close to her again, bringing his hip towards her face. His hand goes behind her and holds her in place so she cannot get away.

She can see his testicles squeezing out of the sides of the tiny garment and is horrified. What on earth does he want from her?

He makes her take the material in her teeth and she's too petrified to resist. Perhaps if she goes along with it he'll let her go?

He twists and pulls away from her and as he does so the side straps on his thong pull apart.

The headmistress lets out a shriek and lets go of the fabric, which pings away having been under a lot of strain.

Paulo's heavy penis and testicles come spilling out from the confines of the pouch and he turns away, planning on teasing her some more.

What if someone were to walk in and see her with a fully naked man in her office? What would people think? Still the music continues to boom out of the music system while the man in front dances before her.

He flicks his thick penis up and down in a manner that usually gets his audience squealing with delight. He can't understand why this woman is making small moaning noises.

Deciding it's time to give her the full benefit of his significant endowment he turns to face her. Seeing the huge thing coming towards her makes her paralysed with fear.

He starts flicking his manhood provocatively at her, the thing coming within a few inches of her face.

The sight of the man's thick member so close to her is too much for her and she breaks her silence with a desperate scream.

"Aaaaaaaaaaaaaagggggggggghhhhhhhhhh!" She's never in her life encountered anyone like Paulo before and is finding the whole experience truly appalling.

Back in the Biology classroom, Miss Marchmont has had more than enough of Martin's behaviour. She bends the tearful lad over her knee ready to administer a good beating. The girls watch keenly, ready to enjoy his humiliation.

She scowls at the young man in her lap. She'll show him what happens to boys who cannot control themselves and disrupt her lesson!

Martin sobs with distress - it seems so unfair that he's going to be punished like this. He didn't mean to ejaculate in front of them all. What kind of physical examination is this anyway? He begins to suspect there has been some kind of mix up.

Miss Marchmont raises her hand in the air and the girls wait excitedly for the impact.

She brings her hand down sharply against Martin's exposed buttocks. A loud slapping sound echoes around the room and the girls break into fits of giggles.

Martin winces, trying not to cry out from the shock of it. The girls' laughter rings in his ears.

The teacher doesn't give him a chance to recover before striking him again.

It hurts just as much as the last time and he lets out a moan "Owwww!".

His buttocks start to glow pink as the stern woman continues to deliver a hard smacking.

Each time she hits him a sharp pain shoots from his backside. Being chastised in this manner is as humiliating as it is uncomfortable.

The girls cannot contain themselves. The sight of Martin Simpson being spanked like this is so funny! His cries of anguish only serve to encourage them.

Whack! The strength of the blow nearly dislodges him from her lap. Miss Marchmont has had a lot of practice at this and is very strong.

"You may be plenty old enough," she admonishes angrily, "but perhaps if you'd had a good spanking when you were younger you could contain yourself."

"Absolute filth!" She finishes. Martin feels utterly wretched and helpless as the woman repeatedly strikes him.

His delicate cheeks become more and more sensitive and start to throb.

But she shows him no mercy, still very annoyed that he has ruined her first day at the school. Wait till the headmistress hears about this!

Cassy jerks his head up, pulling him by the hair causing him to yelp even louder. She hopes they get to do this every Biology lesson from now on. Perhaps with a different boy each time.

Miss Marchmont delivers one last smack. "There. I hope you've learned your lesson."

His buttocks are bright red and smarting from his spanking and he knows it'll be uncomfortable to sit down for the next few days.

He slides awkwardly off and gets to his feet. The look of disgust never leaves the teacher's face.

He can feel everyone staring at him as he stands up, his exposed genitals flopping around between his legs.

He rubs his sore behind, still sobbing. Maybe finally he'll be allowed to get dressed.

But before he can argue, Miss Marchmont grabs him by the ear and starts to lead him towards the door.

"You can get your things later. I want you out of my class," bellows the woman, dragging him along behind her.

Pandemonium erupts as the girls watch Martin being led away and they burst into loud guffaws.

Back out in the corridor, Logan, Vincent and Aiden sit quietly shivering - their earlier bravado gone. Somehow waiting to be called is as bad as actually undergoing the dreaded physical.

Suddenly the sound of a commotion from up the corridor interrupts their thoughts and they all turn to look at the strange sight.

A woman they don't recognise is pulling a totally naked Martin Simpson along by the ear and shouting at him angrily. What on earth has he done? And why is he naked?

"You come here too late and behave completely unprofessionally," she booms into his ear.

The other boys' eyes widen in shock. They are all terrified and struck dumb by her fearsome demeanour.

"And fancy spilling your semen in front of a class full of girls?" She is incensed and ready to lash out at anyone who crosses her.

"But Miss, Miss. It's not my fault. There's been some sort of mix up. I'm sure there's some sort of mix up," Martin says pitifully but he can tell the woman doesn't believe him.

Miss Marchmont suddenly realises they are not alone in the corridor and turns to face the other boys. "What?" She begins to question.

"There certainly has been a mix up. For goodness sake - I only ordered 1, not 4 of you!"

Logan, Vincent and Aiden have no idea what's going on, but suddenly start to feel very nervous as the ferocious woman scowls at them. "Well since you're all here, I'm sure my girls can find a use for you..." Her words fill them all with utter dread.

In another part of St Dunstan's the job interview for the PE position is not going according to plan. A loud Latin beat is emanating from the headmistresses office and inside the horrified woman is being subjected to Paulo's best erotic dance. Now completely naked, the big man twirls around and gyrates in front of her. Will she ever be able to bring order back to the chaos that's occurring throughout the school?

Although it makes him feel incredibly uncomfortable, Paul does as he is told and bends over, pulling his buttocks apart. Nurse Bleifrei waits to ensure he's following her instructions to the letter.

She then leaves him to go and collect what she needs from the trolley in the corner.

Paul is very worried, wondering exactly what the stern woman has in store for him. It feels wrong to be putting himself in such a compromising position.

As a very macho sporty lad he's use to being in full control. It's unnerving to be made to expose his intimate parts to a woman like this.

The nurse returns and walks past, carrying something in her hand that Paul cannot quite see.

He suddenly feels the very strange sensation of a cool, slimy liquid being dribbled between his cheeks. This is followed by the touch of the nurses gloved finger as she smears the stuff around his sphincter. He tenses automatically.

Her finger presses against the entrance to his anus as she works the lubricant in. Paul guesses what it's for but resists the urge to pull away. Having come this far it would be unbearable to blow it now.

Without saying a word, the woman effortlessly slides her finger into Paul's anus. She feels his sphincter tighten around it but expertly works her way past his resistance.

Paul lets out an involuntary yelp of surprise. The sensation is very uncomfortable and makes him feel dirty.

Going about her work and ignoring Paul's moans, the nurse works her finger in and out of his backside.

The boys always seem to kick up a fuss about this part of the test for some reason. But she's very experienced at penetrating young men and doesn't let their protestations stop her from doing her job.

Although the woman has slender, delicate fingers it feels to Paul as though she were ramming a great big rod into him.

It's a sharp, stinging pain that shoots up from the entrance of his bottom and he cannot block it out no matter how hard he tries.

He closes his eyes and winces every time her finger goes in deep. "Are you sure this is strictly necessary?" He whines, "I was told I wasn't old enough to need a prostate exam."

"But this is St Dunstan's!" She exclaims as though that explains everything.

"We take health very seriously here." He wishes they didn't take it quite as seriously as this - but who is he to argue?

Without warning the nurse whips her finger out and Paul breathes a sigh of relief. 'Thank God that's over!' He thinks to himself.

But he can't see behind him that Nurse Bleifrei has got two fingers together ready to go again.

Before he can stand up she presses them against his throbbing sphincter and jams them inside him.

It feels even worse than last time and he has to grit his teeth against the pain.

"Oh!" He exclaims and tears start falling from his eyes. He feels utterly wretched being subjected to such a humiliating ordeal.

The woman is relentless. She has to give his anus a thorough checking - his discomfort is immaterial.

She thinks of all the boys she's still yet to see and picks up her pace, ramming her fingers in and out rapidly.

His careers adviser never warned him that this might be part of a job interview! Paul just wants it all to be over.

His anus feels like it's on fire from the relentless pounding. It's like nothing he's ever experienced before and he hopes he'll never have to endure anything like it again.

"I'm not sure I want to come to this school anymore," he moans, part of him wishing he'd never replied to the job ad.

"Ow!" He shouts as the nurse twists her fingers around inside him as if in response.

"Ha ha! Yes - well lots of boys say that," says Nurse Bleifrei having heard it all before.

"But you'll have to wait until you've passed your exams before you can decide to leave," she chuckles.

'Exams? She must mean this physical,' thinks Paul to himself. "OK, but is there much more to do?" He ask forlornly.

There is another sharp pain as she quickly pulls her fingers out of his anal passage. "Yes. Now get up onto the desk."

He climbs off the desk, unsteady on his legs after the abuse his backside has received.

"I want to put three fingers into you," says the nurse holding them up so he can see. He lets out a deep groan. Oh no - not more!

The headmistress is deeply distressed and cries in misery as Paulo flaps his penis in her face.

"Yes yes lady - I know. Paulo's body make you cry with joy! Here - look at my beautiful ass." He turns around, convinced that she's having a good time and thrusts his backside in her direction.

Her moans increase in volume as he gets closer and closer.

His pulls his cheeks apart and bears down on her. She lets out another shrill scream but there is no one around to hear apart from the excitable Brazilian in front of her.

Her reaction isn't exactly what Paulo's used to but like a true professional he's not put off. He knows just what will get this woman aroused.

"What the?" She begins as he grabs the flag that he'd draped on her desk.

He holds it to his waist and approaches her again. She turns away and gasps. This man is incorrigible! Why doesn't he get the message?

He flicks his heavy penis behind the flag making the material flap towards her. 'This really is too much!' She thinks to herself.

She keeps her eyes averted but is aware of the man's privates just inches from her face.

Even covered by the material of the flag, his weighty member intimidates her.

But she can't help herself and looks round, only to be horrified all over again at his appalling display.

His penis bounces close to her again and the offended woman doesn't know what to do. She pulls back in her chair to get as far away from it as possible.

But thinking she is playing some kind of game, Paulo grabs the back of her head and brings her face close to his groin.

This time he actually makes contact with her, and she can feel the warmth of his throbbing penis as it touches her cheek.

"Mr Paulo please! I can't. I can't take any more of this," she pleads with him.

He tosses the flag aside and she thinks for a moment that maybe she's got through to him.

She realises he has something else in mind and shrinks away from him as he reaches for the can of whipped cream from the desk.

Holding his prized penis in front of her, he begins spraying the cream along the length of his shaft.

The hysterical woman has no idea what he's doing but her instincts tell her she's not going to like it.

"Now you want cream surprise? Yes?" Says Paulo with a glint in his eye.

"Cream susprise?... You don't mean?" The shocked headmistress has a feeling that's exactly what he means.

"Yes naughty lady want cream surprise," and Paulo winks at her.

"No. No. Paulo please!" She sees his thick cream covered manhood come closer to her.

"AAAAAAAHHHHHHHHHHH!!!!!" She shrieks as he wraps the flag around her.

He covers her head and pulls her forward onto him, thrusting his penis into her opened mouth.

A muffled moaning sound comes from underneath the material but the woman is totally trapped and unable to escape.

Paulo is in ecstasy - it's times like this when he loves his job!

"I think you have done this before," he says and the woman is unable to disagree with her mouth full.

He thrusts his hips back and forth, sliding his penis down the unsuspecting woman's throat till she can barely breathe.

"Ah yes. You have very experienced mouth. I can tell," encourages Paulo.

Finally he pulls back and the headmistress gasps for air, her mouth full and her face covered with cream.

She moves as far away from him as she can and gags - utterly wrecked by her experience.

She howls with fear and anger. Just what is going on today? Why is this man behaving like this? Does he really think doing this will get him the PE teacher's job? It's all too much for her and his next words nearly send her over the edge as he looks down at her and says "you want more?"

Paul Williams had no idea that getting a job at St Dunstan's would be so tough. He was expecting to be asked a few questions about sport but that was about it. He certainly wasn't expecting such an intimate and painful physical examination by the school nurse. Everything is happening so quickly and the inexperienced young man feels totally out of his depth. And as if having two fingers inserted into his anus wasn't bad enough, the stern woman has just announced that she intends to put three fingers into him!

Paul looks round at the nurse as she adjusts her glove. Three fingers - that's going to hurt! But it's not in his nature to cross authority figures so he reluctantly clambers onto the desk as instructed.

His penis flops about between his legs as he gets up. He feels sick to his stomach - but the woman must know what she's doing mustn't she?

The woman directs him into position - with his exposed backside pointing up towards her. He tries to prepare himself for the agony to come.

He closes his eyes as he feels her fingers against his sphincter. Surely this isn't necessary? It never occurs to him that maybe a mistake has been made and that this invasive procedure wasn't intended for him.

Having already loosened him up, Nurse Bleifrei has no trouble pressing three fingers into Paul's anal passage.

She keeps applying pressure until her hand is almost entirely inside him.

At the same time she reaches round and grabs hold of his dangling penis. She tugs on it rhythmically.

Tears prick the corners of Paul's eyes once again at the humiliation of it all. He lets out a low wail of pain but the nurse ignores him completely.

She has a job to do and won't be put off by silly schoolboys showing off.

She works her fingers in and out of him while she strokes his penis. It's a test she's performed hundreds of times and she always gets the desired results.

Paul doesn't like the sensation one little bit. The combination of pleasure and pain makes him feel very strange inside and he wishes desperately that she would stop.

A stabbing pain shoots from his backside up his spine as she presses herself into him.

But her manipulation of his penis is starting to get him aroused. He feels himself hardening in her grip and tries to stop it.

It's useless - her tight hold on his member and repeated stroking arouses his passion despite the agony.

He tries to take his mind off the overwhelming sensations but just can't do it. It's as though the woman has taken control of his senses.

"Oh. Oh!" He mumbles, partly in discomfort and partly as a result of his arousal. Beads of sweat form and merge with his salty tears. It's all getting too much for him.

Without warning the nurse whips her fingers out causing him to yelp and momentarily forget the warm pleasurable feelings in his groin.

She walks off leaving Paul wondering what's going on. Is it over? Has she finished? Although glad not to have her fingers in his anus, a small part of him was enjoying her working on his penis.

He sees her across the room getting something from the trolley and guesses he's not going to be let off that easily.

She hurries back carrying a Petri dish in her hand. She needs a special sample from Paul and knows exactly what to do to extract it.

She places the dish between his legs and readies herself to procure a specimen from her subject.

Paul grasps the desk tightly assuming that his anal passage is once again about to be penetrated.

Without further ado, Nurse Bleifrei resumes her position with her three fingers inside Paul and her other hand wrapped around his manhood.

Her actions become more hurried as she determines that Paul isn't far from giving her what she wants.

Paul's mind is awhirl as once again he feels the overpowering and contradictory sensations building up.

He's never had his prostate massaged before and it feels very weird. He can't ignore the way his penis feels in the nurse's strong grip and lets out a moan.

He realises that if she doesn't stop soon then he won't be able to control himself and he'll embarrass himself in front of her.

The nurse starts to get impatient and she tugs on his penis even faster. No young men are able to resist her attentions but sometimes it takes longer than others.

Paul's testicles churn and he knows release is only moments away. He thinks it would be awful if he shot his load in front of the nurse but his resistance is weakening by the second.

"No. No! Please stop," he begs - although part of him wants her to carry on all the way.

"If you carry on I think I might... I might... relieve myself." He's so ashamed of the way he feels that he cannot find the words to express himself.

Nurse Bleifrei merely sighs. That's the whole purpose of the exercise! And she has no intention of stopping now.

"Oh Noooooooooooo!" Moans Paul as the feelings erupt and take him over completely.

Semen shoots from his penis in thick streams into the Petri dish, an equal amount splashing onto the desk.

He bites his lip. The sensation of release is incredible and all he can think about. But deep down he feels utterly wretched at having shamed himself in front of this woman.

The nurse continues to milk the helpless lad, determined to extract every last drop from his testicles.

As a healthy young man there is plenty in there and loads and loads of the stuff is produced as he ejaculates.

She has more than enough for her sample but thinks it best that she drain him fully. He seems a nervous type and in her experience this can help.

Finally the orgasm starts to subside and Nurse Bleifrei squeezes the last few drops of sperm from his penis into the dish.

Paul is totally spent - his testicles empty and his whole being exhausted. His sense of relief is short lived as he is totally aware that ejaculating in front of a member of the school is likely to ruin his chances at getting the job.

The nurse looks down at the Petri dish between Paul's legs finally satisfied that she's extracted all he has to give.

As well as the liquid swilling around in the glass dish there is a fair bit all over the desk. She tuts - annoyed with him for making such a mess.

Still, at least this is one physical nearly over with. But at this rate it's going to take all week to work her way through all the boys in the school!

She extracts her fingers from Paul's anus once again, congratulating herself on a job well done. Paul is still in shock and unable to move.

He can't believe what he's just done. And in front of the nurse too! But at least she hasn't shouted at him. Yet.

"Well, I suppose that'll have to do," says Nurse Bleifrei after what feels like an eternity to Paul. He lies there sobbing and confused. What sort of school is this? He wishes he'd never set foot in the place!

The girls in the Biology room are sat obediently awaiting the return of Miss Marchmont when a commotion from the doorway makes them all sit up and pay attention. They can't believe their eyes as the teacher walks back into the room.

"Girls, girls, stop what you are doing and listen to me," says Miss Marchmont dragging a sorry looking bunch of boys behind her.

She stops and stands there making sure none of them have tried to slip away. Logan is so embarrassed he can't actually look at the girls while Vincent stares at them in shock.

Being in front of a class full of schoolgirls whilst stood in their underpants is terrifying for the boys. Martin hides at the back of the line, covering himself up.

"Owing to a mix-up we actually have three more life models," says the teacher, speaking loudly over the hubbub that has broken out with their arrival.

The girls turn to each other and squeal with delight. The fierce woman continues, "So as not to waste the opportunity you may all have a model each to examine and I will come around to answer any questions." The boys freeze instantly. What did she just say?

She gestures for the boys to walk over to the girls but they stand rooted to the spot. They cannot understand what is happening or why they have been brought into this room. All of them are frightened by the woman standing next to them. But only Martin knows the full horror of what is about to happen to them.

When they arrived at school this morning, Logan, Vincent, Aiden and Martin were full of boyish excitement - looking forward to a day of messing around in class and discussing girls during breaks. Their day took a turn for the worse when the headmistress announced the boys' annual physical. As if this wasn't bad enough, the terrifying new teacher Miss Marchmont has mistaken them for life models. Now they've been dragged into a classroom full of giggling girls and stand there confused and shivering wondering what on earth is going on.

The boys don't move. Did she just say they were 'life models'? What does she mean by that? Surely she's not suggesting that the girls be allowed to touch them? Their stomachs clench at the very thought.

"Come on, come on," insists the woman harshly. She's so intimidating that the boys daren't disobey her so they begin shuffling slowly towards the eagerly awaiting girls.

They can feel the teacher's penetrating gaze on them as they walk past. Unlike their regular teachers, she's an unknown quantity. But something about her demeanour tells them she wouldn't be afraid to administer a painful punishment if they disobey her.

They glance at the excited girls with fear. Just what will this 'examination' involve? They are disturbed that the girls don't seem in the least bit shy or embarrassed by the boys approaching them in their underpants.

Little do they know that the schoolgirls have already had practice with poor Martin Simpson that has left him traumatised.

The girls appraise the boys as they walk past them silently. Tanya and Veronica decide to share Vincent - he looks like he could be trouble and it will be easier to control him if they work together.

The girls swivel their chairs around so they face the boys who stand their dumbly. They are all bewildered by what they've been instructed to do, but none of them has the courage to speak up.

The girls check out each other's models and squeal with delight. What a treat for them! They thoroughly enjoyed having free access to Martin's body, now they can use what they learned from the experience on these new subjects.

And best of all - there's nothing the boys can do about it. The girls know enough about Miss Marchmont to realise that once she's got an idea into her head, nothing will change it.

They waste no time in starting and begin examining the boys' bodies. Dawn starts taking notes about Logan while Tanya and Veronica caress Vincent's exposed torso.

They reach up and pinch his nipples sharply causing him to wince in pain. More used to running around on a sports field, Vincent cannot work out what's going on.

The girls giggle and discuss him openly, touching him wherever they like. It feels wrong to him that they should be treating him like this.

As the school's star athlete he can normally expect to be revered. Yet here he is, having his body judged and described in detail with the girls furiously taking notes.

He wants to say something to make them stop. To protest that this isn't fair. He looks across to Aiden for support.

But he can see his friend is in just an awkward a position as he is. Cassy runs her fingers across his stomach, handling him with total confidence. Aiden gulps and closes his eyes.

"Owe!" He exclaims sulkily as Cassy tweaks his nipple - just as the teacher taught them to do to Martin. Unlike Vincent, he's worked out that the teacher has made a mistake. But as his friends are keeping quiet he decides it would be best to do the same. After all, the examination is sure to be over in a matter of minutes.

Cassy writes down her findings in her notebook. If she works really hard, perhaps she can persuade the teacher to make this a regular part of their lessons.

She squeezes his arm, feeling his muscles and comparing them to Martin. Aiden bites his lip to stop himself from complaining.

But he can't help but let out a small gasp as she squeezes his leg, aware that her hand is dangerously close to his crotch which is protected only by a tiny pair of briefs.

Things are no better for Logan as Dawn takes a keen interest in his body. He can't understand why his friends aren't making a fuss - especially Vincent. He wants to say something himself but daren't risk Miss Marchmont's wrath by being the first to speak out.

Dawn looks up at him and chuckles as she toys with his nipple. It's such a thrill to have a boy all of her own to play with.

She smiles as she writes in her pad. Normally she hates Biology, but she's suddenly discovered an interest she never knew she had. Her grades are bound to improve if the lessons include more practical work like this.

Gaining confidence, she reaches forward and takes hold of the waistband of his underpants. Dare she take them down?

"Hey!" Says Logan in a hushed whisper so that the teacher won't hear, "You can't do that!"

But Dawn merely grins at him, realising that she can do exactly as she pleases. She starts to tug on his underwear and Logan is suddenly very afraid of where this is leading.

Vincent watches the girls as they study him, increasingly alarmed at how close to his privates they are getting.

They discuss his shorts, joking about the childish cartoon on them. Surely this has nothing to do with Biology? But his bigger fear is that his penis or testicles might pop out of the side for all to see.

They begin prodding his bulge with their pens and Vincent freezes in shock. 'They can't do this to me!' He thinks indignantly.

But they can... and more. They pull the elasticated waistband and take a peek. His instinct is to push their hands away, but something tells him that would just attract the teacher's attention.

He hopes desperately the girls will lose interest in that part of his body and move on to somewhere less sensitive.

But to his dismay, they seem to want to expose even more of his privates as Tanya starts to pull his shorts further down.

"Oooh!" Gasps Veronica as his thick penis and heavy balls come into view, "It's quite a big one! I wonder how it compares to Martin's?"

They pull the shorts further and his already thickening penis pings out of their confines. The girls burst into fits of laughter but Vincent is still trying to understand what they just said. How did they get to see Martin's penis?

He can feel a cold draught around his privates as they are now on full display. What will happen now? Will the teacher come marching over and tell the girls off for going too far?

The two girls lean forward to take a close look and he can feel their breath on his penis. Veronica pokes it with her pencil curiously. It looks very different to Martin's.

Despite his discomfort at being naked in front of his friends and the room full of girls, Vincent has a horrible feeling that he's starting to become aroused.

Dawn looks Logan full in the face as she slides his underpants down revealing a thick bush of dark pubic hair. He doesn't like the way she stares at him, it unnerves him that she is so blasé about stripping him.

She seems to delight in taking her time, teasing him as though she might let go and allow him to remain covered up.

But she's not about to waste an opportunity like this and whips his underpants all the way down so that his penis and testicles come spilling out.

She hears him whimper in dismay and it excites her to have so much power over him. She wonders if he will become erect as easily as Martin did and the thought fills her with glee.

Having seen what's happening to his friends, Aiden clings to the hope that he might be spared. Cassy clearly has other intentions though as her hand wanders to his flimsy briefs.

By rights as an inexperienced young woman she should be afraid of what lies inside his underwear. But Cassy doesn't seem to be in the least bit intimidated and seems keen to release his privates from the tight fitting garment.

She pulls the material towards herself and has a look, savouring the moment. With Martin she had to share him with the rest of the girls, but with Aiden she has him all to herself.

Aiden feels queasy as he sees his penis revealed. Cassy's finger brushes against the tip as she stretches the fabric around it and he realises that he is starting to respond.

As she removes his briefs Miss Marchmont walks past and stands beside him. He briefly wonders if she's some to put a stop to all this nonsense.

But she seems to be actively encouraging the girls. "Good! Good!" She says watching Cassy work, "Remember, don't be afraid to get stuck right in." Aiden's heart sinks.

Martin looks across at his friends, getting no pleasure from their discomfort. Seeing them being manhandled as he was brings back horrible memories. The boys are all helpless as the girls freely manipulate their genitals under the watchful eye of the teacher.

What a pleasing sight for Miss Marchmomnt - a row of naked boys in the Biology class with the girls enthusiastically learning from them. It makes her happy to see them applying themselves so readily to their studies. She has no idea of the turmoil going on inside the boys' minds as they stand trapped and unable to resist the unwanted attentions of the girls.

The schoolboys are all terrified of the fearsome new teacher. She seems so stern and bossy that they dare not speak up. As a result they are all stuck in the very uncomfortable position of having to allow the girls to explore their youthful bodies. Now stripped totally naked, they stand their dumbly, hoping that the girls will go easy on them. But the girls aren't going to pass up an opportunity to examine their subjects in the most intimate way possible.

Logan gasps in shock as Dawn immediately starts studying his exposed genitals.

Exclaiming with delight she uses her pen to lift the boy's penis, just like she saw her teacher do.

She leans in closely and Logan can feel her hot breath on him. She takes a long hard look at his testicles. She's aware of the discomfort she's causing him but doesn't care.

She lets his penis flop back down and hurriedly writes down her observations. She desperately wants to impress Miss Marchmont in the hope they'll be allowed to use live models in future lessons.

Martin watches, sharing his friends' discomfort. It was only a short while ago that he was in their position - having the girls touch and caress his naked body. The thought makes him shiver.

Tanya and Veronica discuss Vincent's privates, prodding them with their pens. Veronica notes how wrinkly his scrotum is and they both decide that men's bits and pieces are utterly ridiculous.

Aiden tries not to look at the way Cassy is handling his increasingly engorged penis. He stares across at his friends and can tell by their faces that they are all struggling to control themselves.

"So!" Says Miss Marchmont loudly, breaking the silence, "as you can see - boy's penises are all different." She points to Aiden's member, "This one here is completely different..."

"...from that one over there," she indicates Vincent's penis and he gulps, not liking the extra attention drawn to his privates.

Cassy hangs on her every word as she continues to touch Aiden's penis and testicles. She's in awe of their new Biology teacher and way she's got the boys totally under her control.

She looks and can see what Miss Marchmont means - Aiden's willy is different from both Martin's and Vincent's. Who'd have thought there was so much variety?

"Miss?" Asks Tanya to get the teacher's attention, "can we really do anything we like with our models?"

"Why yes dear, of course," says Miss Marchmont, "they are here for your benefit to improve your education. You may study them as you please." They boys all shudder at her words - wondering what the girls have in mind for them.

Cassy shoves Aiden round and tells him to bend over the desk. "You'd better not try anything on," he says, hoping his bluster will protect him. But she merely laughs at him.

"Miss Marchmont has said I can do anything I like to you," says Cassy and starts to explore his backside.

He can feel her stretching his sphincter as she pulls his cheeks apart. It's deeply unnerving and his instinct is to resist.

"Isn't that right Miss?" Asks Cassy and the woman readily agrees. He realises she has the teacher's full authority. If he doesn't allow her to do whatever she wants he'd have to face Miss Marchmont's wrath.

Wasting no time she inserts her finger into his rectum.

She pushes it in deeply and he lets out a yelp of shock. He's never experienced anything like it in his life and it makes him feel very strange deep inside.

Following her friend's example, Dawn moves Logan into position so she can study his anal passage. Feeling weak at the knees at the prospect, Logan shuffles around - aware that the girl has power over him.

As soon as he's in position she begins, looking at his tightly puckered sphincter in wonder. She's going to enjoy making him squirm by penetrating him!

Logan gulps as he feels the tip of her finger against the entrance to his anus. It seems like an insult to his macho pride to be allowing a girl to enter him - but what choice does he have?

He grunts with pain as she drives her finger into him. He feels like crying with shame but tries his hardest to remain composed and not show any signs of weakness.

Seeing her classmate enjoying herself, Tanya can't help but join in. She leans round and grabs hold of Logan's dangling penis while Miss Marchmont explains something to Veronica.

Tanya refers to her notes about Martin's penis, causally tugging on Logan as she does so. The effect is almost immediate and he cannot stop himself from reacting to her touch.

"Miss, I'm sure his willy is bigger than it was before," says Veronica, pointing to the offending article.

Miss Marchmont steps closer and looks at Vincent threateningly. "I don't doubt it is," she says in a low tone while Veronica studies it from all angles.

"If this happens," she says, tapping his penis with her pen, "you may administer some form of discouragement." The girl wonders what she can do.

But it doesn't take her long to come up with an idea of how to deter Vincent from become erect and turns him around.

Seeing her friend manhandle Vincent and bend him over the desk catches Tanya's interest and she moves back round to join in, abandoning Logan to Dawn.

The girls size-up Vincent's hairy rump. He wants to pull away from their wandering hands, but is aware of Miss Marchmont's watchful eye so keeps totally still. What are they planning?

Thinking that perhaps pain might stop Vincent from becoming aroused, Veronica raises her rolled-up textbook to strike his unprotected buttocks. Tanya eggs her on excitedly.

With a loud thwack that echoes around the room, Veronica brings it firmly down to strike him.

Although naturally quite tough, it's still a shock to Vincent who has to stifle a yelp. Tanya wants a go and uses her hand to slap him.

He is surprised at how much strength she has as she hits him hard. It's humiliating for him to be in such a vulnerable position but with the teacher only inches aware he daren't make a fuss.

Meanwhile, Logan's anus is taking a bashing. Relishing the power she has over him Dawn drives her finger in and out repeatedly.

He lets out a sob of anguish but it has no impact on the determined girl who is enjoying herself far too much to listen.

It's no better for Aiden. Cassy is getting into her stride and taking her time to explore his anal cavity at length.

He winces, closing his eyes against the sharp pain as she penetrates him deeply. At the same time, he finds being roughly handled by her strangely arousing.

Tanya and Veronica work as a team to work over poor Vincent. it's all the worse for him that his best friends are there to witness it.

It's so degrading being spanked by girls! It's not just the discomfort, it's the fact that if word gets out, his bad-boy reputation will be in tatters.

For the two girls it's a wonderful opportunity to bring the cocky lad down a peg or two. And they can't wait to share their experiences with all their friends.

They stop to admire the rosy pink hue they've brought to his buttocks, pleased with the results.

"Here, let me assist you," says Miss Marchmont striding over to Cassy. She takes hold of Aiden's buttocks so the girl has a free hand - which she puts to good use.

She slides it up and down the boy's fast-hardening penis, reminded of how Martin's felt when he became aroused. 'It's so easy to get boys worked up,' she thinks to herself.

"Thanks Miss!" She says sweetly, "I'm learning so much today!" Martin gulps - the memory of his experiences still vivid. Being made to stand there and watch is very distressing.

Aiden holds his head, mixed emotions washing over him. There is anger and frustration at being abused like this. But also a sense of arousal that is building within him.

Having decided she's made an exhaustive study of his rectum, Cassy instructs the boy to stand up. Realising that he has become erect Aiden is reluctant to do so. But a stern word from the girl galvanises him into action.

He stands there, head hung in shame with his engorged penis hanging between his legs. "Oh dear!" Exclaims Cassy, "what's happened here?" Miss Marchmont looks on, appalled.

Tanya and Veronica finally allow Vincent to stand up and it seems their remedial action has failed to stop the randy young lad's behaviour.

Veronica stares in puzzlement at his throbbing member as it bobs about in front of her.

"Erm Miss?" She says, "Vincent's penis is doing something funny." Vincent shudders - now he's for it.

"You filthy young man!" Shouts the teacher angrily, "How dare you try to disrupt my class like this!"

Cassy takes hold of Aiden's manhood and examines it closely. The differences between it and Martin's are far more obvious now.

"This one has done it too!" Calls Cassy from the end as Logan stands up sporting a huge erection.

Miss Marchmont looks from one to the other in disgust. The boys stare at their feet, deeply embarrassed as the girls giggle and look at the spectacle they are making of themselves.

"Good grief! Can none of you boys control yourselves?" She is incensed that these so-called professional models have such little self-control. They are ruining her lesson!

"You are like animals!" She bellows. The boys realise they are all in very deep trouble. They have no idea how the enraged woman will react and stand there petrified. Veronica looks closely at Vincent's penis. "Miss, I have an idea what we can do about it!" She says giving the boys even more to be worried about.

Despite the discomfort at their predicament, and the pain of being anally penetrated, the boys have all had the same reaction to the girls' attentions. Full of testosterone, even the slightest stimulation has caused them to spring erections in front of the class. The teacher is clearly very annoyed with them and they are terrified of what she might do. And Veronica's suggestion of a solution fills them with dread.

The girls look from one boy to the other in excitement. Some of them point upwards, some of them hang down under their own weight, but every one of their penises is clearly engorged.

To have been the cause of the boy's erections is a huge thrill for the girls. And seeing how scared the boys are of Miss Marchmont puts them in the dominant position.

Cassy grabs hold of Aiden's penis and looks up at the teacher. "Are these erections Miss?" She asks inquisitively.

Miss Marchmont turns to look at her. "Yes girls, all these dirty boys have grown erections." The boys feel deeply ashamed at her words.

Eager to see how far Miss Marchmont will let them go, Veronica pipes up: "And they won't be able to do anything more until they've produced that white mess like Martin did?"

"That's right. They need to rub these embarrassing appendages causing them to have what is called EJACULATION."

Veronica see's her opportunity. "So wouldn't it be a good idea if we helped the boys rub their willies so the mess comes out?" She asks innocently.

"Yes girls, a very good suggestion," says the teacher, unable to see another solution to the unwanted erections. "You'll see just how animalistic males can be. They are always being caught masturbating."

Without further ado the girls seize the boys' thick members and begin to tug on them. Martin cringes - knowing just what they are going though. And also knowing that the outcome is inevitable once the girls have made up their minds.

Dawn pulls at Logan's penis, squeezing his testicles at the same time and feeling them twitch in her grip.

She hears him let out a small moan and starts sliding her hand up and down his shaft. Having him so vulnerable and under her control excites her immensely.

Tanya and Veronica work on Vincent together. He's angry at being manipulated like this, but at the same time the poor boy is helpless against their eager caresses.

In fact after only a few seconds he feels a strong tingling sensation building up deep inside him. He tries his best to resist - not wanting to give the girls the satisfaction.

The girls have had practice with Martin however, and are confident they can bring him off whether he wants it or not.

"I think he's nearly there," says Veronica, feeling his testicles clench. Vincent gulps at her words, knowing she's right.

He feels an overwhelming sensation as he reaches orgasm and realises that the girls have won.

"Ooh!" Coos Veronica as the first jet of semen spurts from his penis...

...quickly followed by another thick stream.

She gasps and moves back as more and more of the stuff is produced. Now he's started there's no way Vincent can hold back.

His penis jerks in Tanya's hand as he shoots but she holds on tight.

She's pleased that her subject was the first to ejaculate - perhaps the teacher will give her extra marks!

She looks down at the growing puddle on the floor. Who'd have thought so much liquid could come out of Vincent's testicles.

No wonder boys are always so aggressive, having to carry all that around with them. Perhaps if they let the girls drain them of sperm every day they wouldn't be so distracted.

Miss Marchmont is impressed with how her girls have taken the boy in hand so quickly. She's taught them well.

Eventually the orgasm subsides and Vincent is left feeling foolish and ashamed at having been made to cum in front of his best friends.

Tanya and Veronica examine his penis closely to see if any more stuff is going to come out, but they can see he's totally drained of sperm.

They're still amazed at the volume he's released all over the floor. Far more than Martin managed! This will be something to tell all their other friends at lunch.

Having lost interest in Vincent, Tanya turns to her friend Dawn to see if she can offer her assistance as she works on Logan.

Veronica turns to Cassy - wondering which of the remaining boys will be the next to embarrass himself.

Cassy is in no particular hurry with Aiden. She's enjoying the look of consternation on his face and knows that her touch is driving him wild.

He breathes heavily, totally absorbed by the feelings welling up inside him. It feels so wrong to be feeling this way at school with all his classmates watching - but he cannot help himself.

Cassy thinks it's remarkable how boys penises can change so much - going from soft to hard in a matter of seconds. And how, with just a little teasing, they can be made to produce copious amounts of semen.

Suddenly Aiden can take no more and clenches his fist as he too reaches orgasm.

A thick spray spurts from the tip of his penis just as it did Vincent's.

Cassy starts pumping him hard, determined to extract as much of the sticky white substance as possible.

She thinks she can do better than Tanya and Veronica did with Vincent - Aiden's testicles look like they are much fuller.

She's not in the least bit intimidated by his penis, aware that she is fully in control of him.

Aiden grunts as he ejaculates all over the floor. Even through the haze he can feel the teachers stern gaze on him, along with the rest of the room.

He lets out a sigh as Cassy squeezes out the last few drops. He feels a sense of relief but also one of disgust at himself.

Dawn decides she has teased Logan for long enough and picks up the pace to bring him off.

Although humiliated to be treated like this in front of everyone, Logan doesn't want her to stop as the sensation is overwhelmingly pleasurable.

She looks him right in the eye as if able to read his mind and squeezes his erect penis tightly. It's up to her when he shoots.

She feels she has learned a lot about stimulating boys until they cum after her experiences with Martin. She decides it's time to let him have the release he clearly so desperately wants.

She tugs extra hard and Logan is putty in her hands. His body responds automatically and semen begins firing from him.

All the pent up sexual frustration is released now the flood-gates are opened.

Dawn continues to masturbate the helpless boy, watching the dumb expression on his face with interest.

Miss Marchmont is right, boys really are just simple creatures. They are so easy to control. She can think of a lot of good uses to put her new found skills to when the lesson is over.

She looks down and is pleased to see that Logan isn't letting her down - he's producing just as much as the other two. A testament to her abilities.

The room starts to come back into sharp focus and Logan becomes aware again that he is surrounded by giggling schoolgirls and has just ejaculated in front of them all.

Dawn giggles and smiles up at him knowingly. She'll be on the lookout for other opportunities to hone her new found skills on Logan in future.

The girls look around at the shamed boys, standing there like fools with the last few drips of sperm hanging from the end of their penises. "Right!" Exclaims Miss Marchmont looking at the clock and clapping her hands together.

"Now that unpleasant task is over you girls had better pack up your things and go to your next lesson."

Disappointed that Biology is over so soon the girls reluctantly begin to get their things together. The teacher turns her attention to the boys. "You had better go now as well," she says icily.

"Don't think you've heard the last of this. I shall be speaking to your agency!"

"And demanding a full refund. Such behaviour is unprofessional and inexcusable!"

The boys look at each other in confusion, wondering what the hell she is talking about.

Aiden is totally clueless. All he knows is that this is definitely not the physical examination he was expecting.

"Chop chop!" Says Miss Marchmont as the bell goes, hurrying them all up. The girls pack up and prepare to leave wondering how they can persuade their teacher to make this a regular part of their Biology class. The boys are left shell-shocked and bemused - their experiences will haunt them for the rest of their lives.

While the boys in the Biology room stand there with semen still dripping from their penises, a similar scene is being played out in the nurse's infirmary. Paul Williams has also just ejaculated - made to produce a sperm sample by Nurse Bleifrei whilst inserting her fingers into his anus. The humiliated young man still cannot work out what is going on. Little does he know that the headmistress has mistaken hunky stripper Paolo for him and is having her own uncomfortable experience during the "interview" process.

Paul clambers off the desk as the bell rings, his legs weak from the energy expended when he climaxed. His anal passage throbs painfully from the intrusion by the nurse.

Nurse Bleifrei completely ignores him, reading back through her notes to make sure she hasn't missed anything.

Realising that his examination is over he reaches gratefully for his clothes - keen to be covered up again.

He feels horribly embarrassed by what has just happened, made worse by the utter silence apart from the occasional scratching of the nurse's pen.

He keeps expecting her to say something but it's as though he weren't there.

He glances sideways at her as he pulls his pants up, glad to be able to finally cover his privates. She seems engrossed in what she is doing and it starts to worry him.

Does her silence mean he's failed the test in some way? Is the interview over? When will he hear about the job? A dozen thoughts buzz around his head.

He stands there awkwardly, not sure what to do. Should he just go? Will they write to him or should he call the school in a few days?

The woman's expression is unreadable. It would be heartbreaking not to at least be in the shortlist after all he's had to endure.

It's important to Nurse Bleifrei that her notes be as complete as possible and she pays no attention to the young man stood opposite her in just his underpants. She assumes he must have a lesson to go to.

Paul looks down, vividly remembering the sensation of having the nurse's fingers inside him. As a macho sportsman it's an experience that has shocked him.

If he does get the job, he hopes she will keep his examination results confidential. Imagine how awkward it would be in the staffroom if the other teachers knew that he'd shot his load while the nurse penetrated his anus!

Wondering why he is still here the nurse finally acknowledges him. "Hurry up!" She says thinking he must be a bit slow, "you don't want to miss class."

Paul is confused. "Class?" He asks.

"Yes, you should be going to... erm..." The nurse refers to her notes to see where the boys are supposed to be after the physical, "Geography in room 5b."

"You mean I passed the test?" Paul asks hopefully.

"Yes, yes. You're a healthy young man. Now off you go," Nurse Bleifrei really doesn't have time for this.

Befuddled by the whole experience, Paul holds out his hand to the nurse. "Thank you ma'am. I promise I won't let you down."

With a sigh, the woman takes his hand and shakes it. "Good. I hope not. Have a good afternoon."

Still barely dressed Paul heads for the door. "Geography?" He mutters to himself, "Right, I think I can do that."

He steps out into the corridor just as the bell goes again wondering what teaching at St Dunstan's will be like.

The shocked headmistress is still being entertained by Paulo. Exhausted and covered in cream she whimpers helplessly. But the big man mistakes her moans for pleasure and it simply encourages him.

He pulls her up out of her chair and turns her around, pushing her over her desk. She tries feebly to resist but he's caught up in the moment and continues unabated.

"That's the bell. The bell! I have a class to teach," implores the headmistress.

"You have a lesson right here lady!" says Paolo - still under the impression he's been hired to strip for her.

She shrieks as he presses himself into her, wondering how on earth someone could think this a suitable way to behave at a job interview.

He thrusts his hips back and forth and she can feel his weighty penis bashing against her behind.

She's pushed forward as he grinds into her, tears of distress running down her face.

"No! No! Please..." But nothing she says seems to be getting though.

Paulo rams her hard. He senses she's not quite enjoying herself as much as his clients usually do and is determined to pull out all the stops.

"Yee hah!" He calls out, waving his hand in the air, "I ride you like big horse!"

"Get off me!" She bellows, hoping to get across to him that his advances are unwanted.

"Is OK, I can be gentle too," he says, slowing down.

But instead of stopping he grabs hold of her skirts and starts rubbing himself against her knickers.

He pulls her back and forth against himself thinking that he will win her around with his tenderness. The women love this!

Why, he wouldn't be surprised if she wasn't making a little mess in her panties from all the excitement.

The headmistress manages to regain her composure despite the man thrusting himself against her.

She pulls away and turns around. "That's enough now," she says firmly.

She slumps down wearily into her chair. "I think there has been a massive misunderstanding. I want you to finish this right now."

He looks at her a little shocked. He was only just getting going - normally the women like to get a full show out of him - especially the prices he charges. "Finis!? You want me to finis?"

"Yes!" Says the woman loudly, "I want you to finish RIGHT NOW." She's relieved that at last he seems to be understanding her.

Paulo shrugs. It's her money. "You want picture first yes? Click click!" He mimes taking a photo but the beaten woman merely sobs. Oh no - not more!

He leans across the desk and grabs the headmistress' mobile phone. "NO! I want you to finish," she says hopelessly.

"Sexy lady in such a hurry. Click click first." He grabs her head and points the camera on the phone at the two of them.

"You take this," he says holding her face right up against his penis. She tries to protest but can barely manage to mumble with her mouth pressed into his naked body.

She hears the camera shutter go as he takes picture after picture. "Cover for your Facebook page. I know," he says as though he's read her mind and is acting out her fantasy.

Abruptly he pulls away and puts the phone down. "Now I finis," he pronounces in a tone that fills her with dread.

"What?" Is all she can manage as he grabs hold of his penis and starts pumping it furiously.

It takes a moment for her to realise just what he has in mind, and when she does her heart sinks.

"NO! Stop now! Stop it. No I didn't mean..." But he merely moves in even closer to her.

She looks up at him beseechingly but can see by the vacant expression on his face that he's miles away.

"Really. I have to go now!" She makes as though to get up and leave.

"Is OK. I only take a few seconds now," says Paulo, wondering why she's in such a hurry.

As he speaks he leans forward and holds the tip of his penis against the headmistress' cheek. Seconds later a thick jet of hot semen shoots out of the end.

"AAAAAAAAAAAAAAAAAAAAAGHHHHHHHHHH!!!!!" She wails as more and more of the sticky liquid pump out and dribble down her chin.

Paulo ejaculates copiously - it's one of his specialities and always brings the house down.

"Oh no, oh no. AAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHH" She screams as he shoots all over her face, panting as he does so.

She is covered in the messy stuff and heavy strands hang off of her chin.

Paulo smiles, proud of himself for having delivered such a fantastic show to such a difficult audience. The woman should be delighted - cumming on her face was an extra special treat just for her.

But it's all been too much for the poor woman not used to being treated in such a manner.

"I know. I know. I the best," says Paulo soothingly. "Yes. I the best." He turns off the CD player and at last silence fills the room.

He turns back to the headmistress. "Lady?" He questions. After the shock of having Paulo's genitalia thrust at her and now this, she has fainted dead away. But with the head of the school indisposed, and so much confusion still going on at St Dunstan's, will anyone be able to restore order?

It is the next day and a rather subdued group of boys sit behind the girls in the assembly hall. Their experiences from the previous day will stay with them forever. The embarrassment of getting erections in front of the girls compounded by accidentally ejaculating all over the floor. They are joined by a totally bewildered Paul Williams who still doesn't quite understand what is going on. But more importantly for the school - yesterday's mix-up meant a very important task was never completed.

Unlike the previous morning, there is no laughing and joking between the boys. Having been made to strip and allow their genitals to be touched by the girls they are chastened.

A new face stands at the lectern on the stage in place of the headmistress - the fearsome Miss Marchmont. "Quieten down everyone!" She calls out and instantly the room falls silent.

The girls look at her expectantly. She's already become their new favourite teacher after she let them use the boys as life models for their lesson on male anatomy. Perhaps she'll have another treat in store for them.

"The headmistress has had to take some well earned time off owing to mental exhaustion so I will be taking the assembly today." As she speaks she waves her cane about and the boys eye it uneasily.

The girls exchange looks, wondering what happened to the headmistress. It's not like her to be off sick. Something pretty major must have happened to her.

"Now some important announcements," continues the woman. The boys start to get nervous - after yesterday's ordeal they were hoping assembly would be brief and they could get to their lessons.

"Owing to a mix up, the physical exams were not carried out yesterday. Nurse Bleifrei is unable to do them so we will have to fit them in during assembly." The boys' hearts sink. Oh no! They thought they would be let off the physicals after what happened yesterday.

The girls cannot contain their excitement and start chattering, wondering what the process will entail. They are completely at ease with the sight of male genitalia after their Biology lesson and are eager to see more.

"Boys, all line up by the front," orders Miss Marchmont in a no nonsense voice, indicating with a swish of the cane.

Reluctantly the boys stand up and begin making their way slowly to the stage. The woman terrifies them and they know better than to upset her.

The sound of the girls giggles rings in their ears reminding them of the humiliation they all suffered yesterday.

They delay for as long as they can, wanting to put off the inevitable for as long as possible.

Under Miss Marchmont's watchful gaze they line up next to her. Aiden gets there first and stands uncomfortably - feeling on display with the girls looking up at him.

Paul watches the boys nervously. Yesterday's Geography lesson must have been some sort of induction as he arrived to find a teacher already there and was told to sit with the other students.

Logan joins Aiden, keeping his gaze firmly down to avoid looking at the girls.

Martin and Vincent step onto the stage and finally the boys are all lined up in a row. Martin stares straight ahead, looking at the far wall and trying not to shake.

The girls fidget in their seats, barely able to contain themselves.

Dawn looks round at the stranger, wondering why he's not up with the other boys. Then Miss Marchmont says the words they were hoping to hear: "Girls I will need your help for this." For the boys, this is the worst thing she could have said.

The schoolgirls rush up and seize Martin Simpson, pulling him to the centre and surrounding him. They never expected to get the opportunity to strip him again so soon.

Cassy starts unbuttoning his blazer and the frightened lad gulps. He can't believe that he's going to be casually stripped by the girls all over again!

He feels utterly helpless, knowing that there is no way to get out of the physical exam, but dreading being exposed and wondering what the girls will do to him.

Dawn and Cassy grab hold of his belt and unbuckle it. Martin is aware that his friends are stood right next to him and will be there to witness his humiliation this time.

Moments later and his trousers drop to the floor. Martin just wishes they would hurry up and get it over and done with. But the girls don't rush, savouring the moment.

His experiences in the Biology room have made him even more nervous and every second he has to stand there increases his trepidation.

He's aware that the girls have the full authority of the strict teacher, and that she is standing close by with her cane should any of them misbehave.

Dawn and Cassy grab hold of the waistband of his underpants. He wants to tell them to stop it, to leave him alone - but what can he do?

They pull on the flimsy material exposing his penis. They all lean in close to take a good look.

They roll his underpants down and his organ comes tumbling out into view. They all gasp, before breaking into fits of laughter.

Dawn lets the elastic ping back against Martin's leg and the sound of their mocking guffaws deafens him.

Cassy quickly slips his underwear off leaving him totally exposed. Martin quivers, the memories from yesterday come flooding back.

Feeling completely confident, Cassy reaches down and takes hold of Martin's penis. After Miss Marchmont's very illumination lesson she has no fear of handling a boy's genitals.

She expertly slides back his foreskin and the other girls watch with undisguised interest.

"Well it looks a lot smaller than yesterday," says Tanya as Dawn prepares to measure the length of his penis. Martin certainly doesn't want a repeat of yesterday's embarrassment and hopes his thing behaves itself today.

Cassy holds the tip and pulls it out to its full length while Dawn places the tape measure along the shaft. Martin holds his breath.

Tanya leans over to read the measurement and Veronica waits keenly to hear the result.

"Martin Simpson's penis is five inches long," she calls out in a loud clear voice that makes him wince with shame. 'They can probably hear it in the corridor and playground!' He thinks to himself.

Veronica rushes over to write it down on the chart on the wall. Cassy lets go and Martin's penis flops down against his testicles.

Veronica writes a large number 5 in the box under 'week 1' - and Martin realises to his dismay that this is going to be a regular occurrence.

He stands there forlornly. Not only is the length of his penis written on a chart for the whole school to see but it looks like he's going to have to undergo this humiliation every week!

"You may get dressed now," says Miss Marchmont and Martin hurriedly pulls up his underpants, glad to be able to cover himself up. "I wonder who will have the biggest one?" says Tanya to Dawn and the other boys shuffle nervously.

The girls break into renewed laughter as Martin nearly falls over trying to pull his trousers up and get off the stage as quickly as possible.

He feels sick to his stomach but at least his ordeal is over for now. But the knowledge that every week he is going to have to stand at the front of the assembly and submit to being stripped and measured by the girls is horrifying.

He rushes off, stuffing his shirt into his trousers and doing up his fly as he goes - desperate to be away from the girls.

With Martin gone the girls thoughts turn to the rest of the boys stood waiting in line. There's a lot to get through but Miss Marchmont seems happy for them to take their time. Who wants to go to boring lessons when they can be pulling the boys' trousers down and toying with their penises? Cassy looks across at where Aiden stands nervously. "NEXT!" She calls out in a commanding voice.

Martin, Logan, Aiden and Vincent were hoping they'd got away without having to undergo the annual physical examination. But Miss Marchmont had other ideas - she's lined the boys up next to the stage and is insisting they each have their penises measured. The other boys watched in horror as the girls pounced on Martin and striped him. His ordeal may now be over, but the girls are just getting into their stride. It's time for the next lad to submit to the eager schoolgirls.

Aiden reluctantly makes his way onto the raised stage. He tries to affect a swagger, but his nervousness is clear to the awaiting girls.

They surround him and he feels their wandering hands groping his body as they giggle excitedly. Tanya leans forward and has no reservations about prodding his crotch.

She slides her finger inside his fly. "Oooh!" She exclaims, "I wonder what we'll find in here?"

As Dawn and Cassy seize hold of his belt he mumbles in protest. But a sharp cough from the teacher brandishing the cane just behind him reminds him to keep in line.

He's helpless to resist as the girls unzip his fly, their confidence increasing with every second.

His tight fitting underpants are revealed and the girls crowd in close to look at the obvious bulge - trying to guess whether he'll be bigger or smaller than Martin.

Tanya uses her fingers to take a rough measurement. "I think he's smaller than the last one," she says. "Well we'll soon see won't we!" Replies Tanya and breaks into fits of mocking laughter.

It's hell for Aiden having to stand there and allow the girls to laugh at him as they freely poke his covered genitals. It's insulting. But the threat of what will happen if he refuses to go along with it leaves him with no choice.

Cassy cannot resist and starts to pull down his underwear revealing his bushy pubes and the base of his penis. Tanya starts speculating about his size again. "It definitely looks smaller to me," she proclaims.

"Wait till we measure it," says Dawn, as Cassy pulls his underpants down further revealing the whole of his penis and his testicles.

Aiden looks forlornly down as his privates are brought into view. Memories of the previous day come flooding back and he shivers, all pretence at bravado gone.

Vincent and Logan bow their heads, trying to block out the girls' shrieks. For them having to wait is almost as bad as what's to come.

Cassy grabs Aiden's exposed penis and stretches it to its full length. Veronica stands keenly with her pen, poised to rush over to the scoreboard and write down the results.

Tanya brings the tape measure alongside Aiden's member and the girls await her reading. "It's 4.5 inches!" She proclaims at last, "Smaller than Martin Simpson."

Veronica dashes over to the chart keen to do her bit. She can't wait to tell all her other friends to come by and take a look.

She writes down Aiden's measurement nice and clearly so everyone will be able to see it as he stands there feeling wretched. "Never mind Aiden maybe it'll grow by next week," says Cassy with a smirk.

It's bad enough to have had his penis measured, but to find out that he's smaller than Martin is just so humiliating.

Having seen how big his penis is, the girls lose all interest in Aiden and usher him off the stage. He grabs his underpants and pulls them up gladly.

The girls watch him impatiently, waving him to move on as they want to see how the next boy measures up.

He grabs his trousers and shuffles away dejectedly. "Bye bye," says Tanya sarcastically, "see you in a week."

Hearing the girls call "next", Logan takes his place. Although not keen to be mauled by the girls he doesn't envy Vincent who's having to wait till last to get the ordeal over and done with.

The girls cheer and clap as he approaches. He feels like he's entering a lion's den and it takes all his courage to step into the space between the baying girls.

He gulps, feeling very uncomfortable and trapped with them moving closer. Knowing he's going to be compared to his friends makes the process even more demeaning.

He doesn't have to wait long before the girls subject him to their "inspection" - their hands moving across his body freely.

Tanya and Veronica exchange glances, wondering how Logan will fare in the penis size stakes. Meanwhile Tanya and Cassy tug his belt open expertly.

Logan watches as the girls fiddle with his fly - they seem to be taking an age! It's almost as if they are enjoying making him suffer.

The schoolgirls break into fresh fits of giggles as they reveal his brightly coloured cartoon underpants. "I bet his mum bought them for him!" Shrieks Veronica, pointing at them.

His trousers are soon down around his ankles and the girls continue to discuss his choice of underwear. It doesn't seem fair that he should be judged so harshly.

Tanya grabs hold of the waistband and stretches the fabric tight. Logan guesses her intentions but is unable to do anything to stop her.

She lets go and it pings back sharply against his skin, stinging him. He has to suppress a yelp not wanting to attract the attention of Miss Marchmont who is hovering nearby.

Dawn and Cassy take a peek at what's nestling inside his underpants. "Let us see!" Call Tanya and Veronica impatiently.

The others obligingly pull his briefs down and Logan cringes. He feels so helpless as the girls oh-so-slowly reveal his privates to everyone in the room.

Moments later his penis and testicles come spilling out into view - much to the delight of the assembled girls.

"Well it looks smaller than Martin's to me," cuts in Tanya, "but maybe bigger than Aiden's." She shrugs her shoulders unable to decide. Logan sincerely hopes his penis isn't the smallest.

The girls make him wait to find out as Cassy takes him in her hand. They seem to be doing everything at a leisurely pace and with every second Logan's discomfort increases.

Cassy stretches his penis to its full length as she did with the previous two. The tension in the room mounts and for Logan it's almost unbearable.

Dawn gets her tape measure ready, enjoying the way the boy next to her is squirming with anticipation. She makes him wait while she untangles it.

Finally she places it along the shaft of Logan's penis. The plastic material feels cold against him and he holds his breath waiting for someone to announce the result.

Tanya jumps up and practically shouts: "It's exactly the same as Aiden's! That's another 4 and a half inches." Veronica rushes off to do her duty.

"Who'd have thought that meek Martin Simpson would be the leader?" Squawks Veronica after furiously writing down the latest measurement.

The girls casually dismiss Logan as they did Aiden and he reaches for his underpants and trousers. He's relieved he isn't the smallest, but wishes his penis were bigger than Martin's.

He nearly trips over in his eagerness to be away from the girls. Their mocking laughter will stay with him forever as he fumbles with his trousers trying to pull them up as he goes.

The girls are warmed up nicely and ready for more. Now is their chance to get their hands on sporty Vincent and find out once and for all which of the four friends has the biggest penis. The traumatised boy steps slowly forward towards the group of girls hoping they'll be gentle with him.

Vincent is the last boy to be called up on stage. Having witnessed his friends' embarrassment he's well aware of what lies in store and the waiting has been agony. But it looks like this distressing process is going to be a regular thing, with each boy's measurement written up on a chart for all to see. The girls aren't complaining however - any opportunity to get their hands on the boys is fine by them. With the stern Miss Marchmont swishing her cane as a warning, the annual physical continues...

Sporty Vincent is used to being adored by giggling schoolgirls for his prowess on the field. But his reception on stage is very different. Their laughter mocking, he's aware that the girls are in charge and he is under their control.

He cannot look at them as they rush forward and start stripping him immediately. It goes against all his instincts just to stand there, but he knows there will be consequences if he fights back.

Their hands roam freely across his body, poking and prodding him as they openly discuss him. He feels wretched but knows there's no chance of escape.

Tanya and Dawn are excited to find out if Vincent has a bigger penis than the other boys. They always suspected he had and now they will get the chance to find out.

But they don't want to rush such a pleasurable task. Besides, it's fun trying to work out how big he is by checking out the bulge in his trousers. They are fully aware that he would fight back if he could and are taking full advantage of the situation.

"I wonder if he can beat Martin's score?" Questions Veronica. Vincent doesn't like the way he's being compared to his friends, it makes him feel very uncomfortable knowing he'll have to face them all afterwards.

Cassy meanwhile applies herself to taking Vincent's trousers down. He watches as she teasingly slides his zipper down, knowing that in a matter of moments he'll be exposed.

The girls howl with laughter as his brightly coloured underpants are revealed - exactly the same style as yesterday. How could such a macho lad wear such silly pants?

Vincent regrets having chosen them this morning, but he was never expecting they'd be revealed in front of everyone during assembly.

Dawn and Cassy slide his trousers down and Veronica hovers ready with her pen. The girls are delighted to think this is going to be a regular event - it will be interesting to see if the boys penises grow over time.

Tanya runs her finger down the visible bulge in the front of Vincent's underwear and Veronica joins in. He cannot believe the girls are allowed to touch him like this! But he can feel Miss Marchmont's presence behind him and knows they have her full authority.

Tanya tugs on the stretchy material, pulling it tight against his genitals, pretending to be interested in the cartoons depicted on the front.

But Dawn is far more blatant and grabs the waistband so she can get a look at what's nestling inside.

They could just whip his pants down and get it over with - but where's the fun in that? They are enjoying making the boy wait while they toy with him.

Vincent hates being in such a vulnerable position - at the girls' whims. He just wants it to be over so he can go and sit down. Never has an assembly been so traumatic.

The time has come for adding Vincent's stats to the chart and with a tug his penis and testicles tumble out of the confines of his underpants.

Cassy reaches in to take hold of his penis and the others crowd in closer. Vincent gulps - having his manhood handled by the girls makes him very nervous indeed.

Cassy grabs him and rolls his foreskin back so they can get an accurate measurement. He holds his breath as she touches him feeling very exposed.

Dawn brings the tape measure alongside the shaft. She and Cassy fuss trying to get the two lined up putting Vincent even more on edge.

He looks away feeling deeply ashamed at having his privates played around with and judged like this. It's made all the worse by the fact that his friends are all sat in front of the stage watching his torment.

"Well he's beaten Martin," calls out Tanya, "he's five and a half inches!" Although relieved not to be the smallest, it's still a humiliating experience to have the size of his private parts read out loud.

Cassy cannot resist one more feel of Vincent's privates as Veronica does her duty and writes his measurement up in big clear numbers.

She lets him go and Vincent fumbles with his underpants wanting to be as far away as possible from the grinning girls. The knowledge that this isn't the last time he'll be in this situation makes him feel sick.

Miss Marchmont's attention wanders away from her girls while the boy pulls up his trousers, relieved to be able to cover himself up again.

This girls are sorry that their fun is over, but they've enjoyed themselves immensely and can't wait to tell all their friends about it.

But Miss Marchmont has noticed there is one young man who hasn't presented himself to the girls for examination. This cannot be tolerated!

"Paul? Paul Williams?" She calls out in a loud clear voice, "Come up her immediately and have your penis length measured." The girls all turn to look at the new face sat amongst the others.

Paul is horrified. Surely he's already undergone a physical exam? "But?" He starts to protest - desperate to avoid the same fate as the other boys.

"I said immediately!" The teacher's voice hardens, "You may be new to St Dunstan's but that doesn't mean you can escape having your penis measured by the girls every week."

The girls are ecstatic! Now they have a completely new boy to play with. And this one seems bigger and more grown up than the others.

Paul nervously makes his way onto the stage. He feels he should exert his authority somehow, but cowers under the intense looks the girls give him.

The girls treat him with exactly the same disregard as the other boys. To them he is merely another one to be measured. He's an unknown quantity and they are looking forward to see how he fares in the rankings.

He doesn't know what to do as they buzz around him and touch him. Surely this isn't the way pupils treat their teachers at St Dunstan's?

But like the others before him, he is intimidated by Miss Marchmont and her cane - so realises he'll have to go along with it as the girls undo his belt.

They gasp aloud as they see that he's wearing very expensive underwear. Well that's certainly a change! This one is clearly a cut above the rest.

"I don't recognise him do you? I wonder who he is?" Veronica whispers to her friends. They are all intrigued by this tall stranger.

But it doesn't stop them from pulling his trousers right down and breaking into fits of raucous laughter. Paul bows his head in shame. How is he supposed to teach these pupils when they take liberties like this?

They pull his underpants so they can all get a good look and Veronica jiggles his testicles about. This looks promising - there might be a challenger to Vincent.

Cassy starts to drag his underwear down and his penis rolls out into view. The girls are mesmerised and savour every moment.

He stares down and tries to block out the girls cackles. His first day on the job and he's having his pants pulled down and his privates shown off to everyone! He has to fight back tears knowing that he'd completely lose their respect if he started sobbing.

His penis and testicles certainly look pretty substantial and he's very hairy. He seems more mature than the other boys - this could be interesting.

"What do you think, five and a half inches like Vincent?" Asks Tanya and Dawn pulls a face. "Nah - I think he'll just about be five." Paul's face reddens with embarrassment - he wishes they'd just shut up and get on with it.

He gets his wish as Cassy takes hold of his penis and starts to pull on it. Paul stands rigidly, petrified that his intimate parts are being handled like this.

While Cassy stretches it to its full length, the other girls hover impatiently. They want to know if this new boy is better endowed than the others.

Dawn moves in to take the measurement. Paul tries to steady his nerves but his heart is beating fast and he feels a little faint.

Everything about St Dunstan's is confusing for the poor lad. Having been stripped, anally penetrated and masturbated by the school nurse yesterday he thought he had passed the physical examination. Yet here he is, once again with his genitals out and at the mercy of females.

"Blimey!" Exclaims Dawn, "I think we have a winner!" Tanya lets out an "ooh" of surprise having seen the results.

Veronica hurries over to the chart and adds in Paul's name in an empty row. She writes it nice and big so it'll be easy for people to read.

Paul quickly pulls up his trousers. He can feel the girls' gazes and keeps his eyes down. All he wants is to get out of this place and go home to his mum. But he has a feeling that won't be so easy.

The girls check out his backside as he departs. Dawn intends to suggest Paul would make a good life model for their next Biology lesson.

"It's official," says Veronica with glee, "Paul Williams has the biggest penis of them all at six inches!"

The girls returns to their seats with the crestfallen boys behind them. "First thing every Monday morning we will update these results. Never let it be said that St Dunstan's doesn't take the health of its students seriously," says Miss Marchmont and the boys groan inwardly.

Hearing a noise from the other side of the room the teacher looks over. "Ah, now everyone," she says seeing someone walk into the room.

"Boys, please put your name down to play in the school football team," she continues.

"Line up and give your names to your new PE teacher - Mr Paulo."

All their heads turn at once as they look at the big man who's just entered. "I am your new PE teacher Mr Paolo," he says with a thick accent. After all the mix-ups and confusion of the last few days it seems that it's a return to business as usual at St Dunstan's.
