PART 1: Mr Derek has designed this new Foundation course on muscles and bodybuilding only with young men in mind. He imagined a classroom full of lithe young men all eager to pump up their bodies to become a physically impressive masculine specimen just like him. But this progressive school wants its students of both genders to receive equal education and encourage all their burgeoning curiosities...
Mr Derek carefully writes out each word on the blackboard. He's more comfortable in the gym than at the front of the class so he really wants to make a good impression.
Ms Charlesworth slips into the room. So this is the big hunk that all the ladies have been chirping about in the teacher's break room!
She surveys his list of topics with a critical eye as well as his broad back and pert arse in those tight trousers.
She pipes up, "Mr Derek. I hope you will be inclusive with your class about bodybuilding. There will be female students as well as male in this class."
"Girls?" he says perplexed. "Oh I didn't know. Why are they here?"
Ms Charlesworth is amazed at this dense lunkhead. "Girls need education about physical fitness too. We have an all-round curriculum here."
"Oh erm... certainly Miss," he stumbles over his words as if he were a nervous student himself.
Ms Charlesworth strides out and nearly collides with a male student as she exists.
He shrinks back as she exits imperially.
He notices two pretty girls coming to the door. He thinks these ditzy young birds must be lost.
Nicola looks up into his crystal blue eyes with curiosity. Is this....? She's heard rumours about this boy!
"It's bodybuilding in here girls," he says blocking their entrance.
"Yeah," Nicola sneers at his arrogant tone.
"Cooking and cleaning is down the corridor."
Kimberley is shocked at his stupid chauvinism: "We know that. We chose physical fitness foundation study."
They breeze past him and Chris is left standing there confused. How can they be his equal in a class all about bodybuilding?
He's been looking forward to this class all summer and dreamed about learning how to build himself up to be as strong as The Rock.
Nicola sits down ready to learn but her imagination starts going thinking about handsome Chris' tender pink lips.
He sits back so his trousers bunch up and strain against his crotch.
His balls and cock press against the tight fabric and he has to shift himself frequently to stop his penis from becoming stimulated from being so tightly constrained.
Nicola whispers "He's a complete chauvinist but look at his bulge!"
"Rumour is he has a big prick and massive nuts. I'd love to get him naked. I think he'll be my next prey."
Mr Derek clears his throat and begins "Of all the sports Bodybuilding is the most competitive and at the same time most rewarding for young men... erm, and girls."
The girls dutifully take notes but can't get their minds off from Chris' promising looking crotch. How big is his penis? Are both his testicles the same size?
Nicola imagines him in the gym shower comparing his muscles against other boys' to see who has the biggest, but at the same time they must be secretly checking to see who has the biggest prick.
"I hope you're writing all this down," Kimberley hisses at him. "There could be a test."
"Pfft... I know all this already," he says confidently sitting back and giving her another chance to ogle his prominent package.
Mr Derek continues reading from his notes "We'll be covering Nutrition (protein), Testosterone, Muscle building, Competition and Posing."
Ms Charlesworth abruptly enters again and declares "Mr Derek I will be assessing you today. I'll sit at the back taking notes."
He fights down an inner sense of panic. He was nervous enough delivering his first lesson but now he'll be even more on his toes with the superior teacher watching him.
He watches her confidently stride to the back with her teachers' robes billowing out behind her like an intimidating figure of authority.
Later on... the lesson is continuing exactly as Mr Derek so carefully planned. "Now testosterone..."
"Once a boy hits puberty at around the age of 14 his..."
He stops himself looking around at the girls uncertain about speaking of something so intimate.
"... his testicles grow in size and start producing vast amounts of a hormone called testosterone." He begins sweating from his nerves.
Kimberley eagerly raises her hand, "What are testicles, Sir?"
"Well erm Kimberely..." He's struck dumb. "Let's just say you don't have them. Chris does."
"We all know that," Nicola says imagining Chris' big package again.
Mr Derek carries on regardless, "This is why after puberty young men are far stronger than girls..."
Chris eagerly jumps in, "So that's why girls are weaker than boys?"
"Yes Chris," Mr Derek says with certainty. "Girls are physically weaker than boys. And this is why they tend to grow up rather neurotic."
Kimberely pipes up with a clever piece of logic, "You're very strong aren't you Mr Derek? Does that mean you have large testicles?"
Mr Derek is dumbfounded and doesn't know how to respond. Nicola eagerly chimes in "Does that mean you have a large penis too? I mean your dick."
Amidst his speechless embarrassment the bell rings and everyone gathers up their things.
Ms Charlesworth is taking many notes with her red pen. This big lunkhead really has no idea how to handle himself with such precocious clever girls!
The students file out and Mr Derek calls after them, "We'll continue this lesson after lunch when we will study competitive bodybuilding."
He looks at her with all the eagerness of a puppy seeking approval. She declares, "I am concerned you are not including the girls as much as the boys. This afternoon I want to see some REAL effort of getting the girls involved. I'm sure you'd like to pass your assessment..."
PART 2: Mr Derek took it for granted that his class would have nothing but male pupils in it. So it's come as a huge surprise to find girls attending his course as well! Now he's completely thrown off by their intimate questions and Ms Charlesworth is demanding that he include them more. But how can he make this class enough fun for girls as well?!
The new teacher stares at the Headmistress in confusion. "Do we have an understanding, Mr Derek?" Ms Charlesworth insists.
"The girls will have some practical involvement in the class, yes?"
"I've... uh... I've always found it a bit difficult to..." he blunders but seeing the stern look on her face he corrects himself. "Absolutely Miss."
Nicola and Kimberley are hanging in the school corridor chatting.
"What a cheek saying girls are weaker than boys," Nicola says angrily.
"We know that's not true. Girls control boys," Kimberley says confidently.
"That's the truth! Girls are far stronger."
Chris passes by the girls on his way to the toilet.
Kimberley has three brothers. She knows that sheepish look anywhere!
Nicola sees from the look in her friend's eyes that she understands exactly what this boy is going to do. He's nipped into the loo for a secret wank! "With those bulging nuts I'd say 2 minutes. 3 minutes tops."
"Testicles!" Kimberley giggles feverishly imagining what Chris' look like.
Chris sighs going into a cubicle and locking the door firmly behind him.
Lately it feels like he can't walk down the school corridor and passing all the sexy schoolgirls without getting a boner.
He knows he needs to take care of this and sort himself out or he'll be struggling to conceal his erection through the rest of today's course.
He picks out a reliable video that will help him drift away into his filthy imagination and have a really good wank.
The girls sneak inside with phones at the ready and grinning from ear to ear in excitement.
They creep in trying to be quiet and already feeling a thrill and rush from being inside this forbidden room!
They can hear some very faint music coming from one stall and the sound of rustling.
Crouching down quickly they sneak a view of who is inside.
OMG! Those are Chris' trousers bunched around his ankles! He must be sat there totally exposed!
He is totally enraptured watching the video and his mind fills with all sorts of crazy thoughts like screwing Ms Charlesworth in the middle of the cafeteria.
As he strokes his cock he thinks about all the girls in the school surrounding him and cheering him on, hiking up their skirts and begging for a taste of his thick juicy nob!
Kimberley giggles in excitement but Nicola quickly hushes her.
They place a bin upside down and hoist themselves up to sneak a peek over the top of the stall door.
Chris is really getting into a rhythm now imagining cumming all over Mrs Charlesworth's face, her tits, everywhere!
The girls are agog at what they're seeing! Chris with his cock out and it's so big and hard!
He pants furiously picturing what it'd be like to cum all over every girl in the school, feeling Mr Derek pat his back in appreciation and say what a good job he did.
They gasp and watch him getting so uncontrollably excited stroking himself like a filthy perv!
With the sound of the video in his ears, Chris doesn't even realise how loudly he's moaning as he feels a warm rush through his body.
Kimberley is losing all self control, but Nicola cannily holds up her phone and hits record.
They're really getting it! Popular boy Chris having a dirty wank! Right in the middle of school!!!
Suddenly he thinks he sees some movement and glances up.
The girls burst into simultaneous laughter. "Caught you! Don't worry, Chris Turner! We have it all recorded!"
He cringes and covers his genitals, but it's too late! He knows he's been found out. He's riddled through with shame!
The girls clamber down, clutching each other and bursting into fits of laughter. "I wonder how many likes this video will get?" Kimberley wonders aloud.
Quickly they race out of the boys' toilets with Nicola's phone clutched safely in her hand.
Chris cringes on the seat feeling his dick slowly wilt in his hand. He wishes he could curl into a ball and disappear. But the bell rings and its time to get back to class.
The girls are already sat in their seats. Watching the video. Enlarging the video. Taking screen shots. Playing it over and over! "Look at his nuts bouncing up and down," Kimberley says loudly.
Chris sits down feeling utterly mortified. This is the worst thing that could ever happen! Nicola comments, "Pulling on his prick. Disgusting boy."
"I can't wait to share this around," Kimberley says so that Chris can hear.
He thinks he's going to have to change school. Change towns. Move out of the fucking country! No way can he ever live this embarrassment down!
"You'd better stay behind after this lesson if you know what's good for you," Nicola warns him. He's not going anywhere. They own his arse now!
PART 3: It's bad enough that Chris has been caught jerking off in the boys' toilets, but the girls also took a video of it. He can't help imagining everyone in his life watching it and laughing at his shame! His friends, his neightbours, his family, his ancient old auntie! Everyone will see him tugging on his prick with his balls ready to burst! What can he do?!
Ms Charlesworth stands at the front of the class to make an announcement, "I need a volunteer to go and clear litter off the girls' hockey field before tonight's match." The girls look expectantly at Chris.
Chris bolts up and agrees to go help. "Very good Chris Turner," Ms Charlesworth says. "Go and see Ms Bullock to get a bin bag."
He's relieved to at least get away from the girls' stares for a few minutes even if it means having to do humiliating chores.
Mr Derek nervously enters again shuffling his papers and is instantly met with the Headmistress' stern gaze.
He clears his throat and fumbles with a piece of chalk.
His mind has been racing how to get the girls more involved. If only he had a figure he could model for the class so they could participate more.
He can feel Ms Charlesworth's eyes burning into his back as he writes on the board with a shaky hand.
Mr Derek carefully forms out each letter and already feels himself sweating under his carefully ironed shirt.
"And what is the topic today?" she inquires.
"This afternoon I will discuss how to pose for a bodybuilding competition."
"I have some diagrams... and I can... erm... draw how the different positions..."
"Mr Derek. I thought we discussed this over lunch. You should pose so that the girls can see."
He stands with his hands on his hips unsure how to go about this. How will the girls be able to see what the poses look like while he's wearing this suit?
Ms Charlesworth sighs undoing his collar. This one is really not very smart.
But she knows how to take a man in hand and get the job done. And she's intensely curious about what he does look like under this monkey suit.
Mr Derek frowns feeling that this is really inappropriate, but how can he deny the Headmistress?
Nicola is wide eyed in wonder. Mr Derek's body looks so different to Chris' she wonders how it is that men come in so many different shapes and sizes?
He got out of body competitions because he was tired of being objectified, but here he is again being stripped down in front of a crowd... treated like a piece of meat!
He hunches over sheepishly while Ms Charlesworth tosses his shirt away as if it were an old rag.
A shock of terror goes through his body as he feels the Headmistress confidently seize his trousers and undo them!
She peels them open and is shocked at the garish colour of his pants. Oh my! What a deviant!
Kimberley feels herself getting warm under her collar. Here's this big hunky teacher being opened up like a present for her!
She efficiently takes off his shoes so she can get these cumbersome trousers off completely.
That's more like it! Now the girls can really see what posing is like.
She leads the humiliated man to stand before the girls so that they can see properly. "Touch the legs," she encourages them.
Nicola eagerly places her hand on his massive thigh. It looks so small against his big powerful haunches!
Kimberley eagerly reaches over to have a feel as well. His flesh is so warm and alive! Like hot steel!
"Feel free to explore girls," Ms Charlesworth eggs them on.
Kimberley lets her hand slide down between his thighs and inch upward...
Mr Derek freezes in place feeling the girls light touch stroke over the circumference of his balls and cock!
He wants to order the girls to stop, but this must be what the Headmistress meant about getting the girls involved. If he stops them now she'll toss him out of the teaching profession forever!
Nicola's hand drifts between the hulking man's legs as well. "Is this where the... what was it called?"
"Testicles," Kimberley says confidently letting her hand slide down his hard torso.
The girls are brimming with excitement getting such a close intimate feel of this powerful man's body!
"Yes," Nicola says. "the testicles and they produce the... erm..."
"Testosterone," Kimberley says confidently.
Every word these girls says increases Mr Derek's considerable humiliation.
"Let me show you," Miss takes the strap of his bikini briefs and makes a simple snip!
The girls stare in amazement as the tiny fabric falls aside and his genitals come tumbling out!
Ms Charlesworth rips it aside to expose him fully and Mr Derek is too shocked to know what to do!
He sees the girls staring directly at his dick and balls and feels himself cringe in utter embarrassment.
The girls are amazed! Not only by seeing their teacher's genitals in every detail but thinking about his body in comparison to the boy they just saw getting himself off! This is a day full of surprises...
PART 4: Nicola and Kimberley were already buzzing off from catching sexy schoolboy Chris tugging on his willy in the gents, but now they are being treated to a show by a much more developed buff man! Mr Derek has competed in bodybuilding competitions all over the country so posing for a couple of girls should be a cinch, right? But the big oaf looks absolutely petrified!
Mr Derek is shocked that Ms Charlesworth has so assertively snipped his only covering so that now he is totally exposed!
Nicola and Kimberley gape as his tiny pants fall away so that his big heavy sack and cowled mushroom tumble into view!
The girls are so close they can smell the musky manly fragrance emanating from his muscular beefy body.
"Go on girls, explore this man's body..." Ms Charlesworth demands.
Kimberley doesn't need to be told twice! She instantly reaches out curious at the texture and weight of that wrinkled meaty sack.
"Are these normal size Miss?" she says stroking the silky flesh.
"Mr Derek's dick is very small..." Kimberley observes.
"Yes Miss," Nicola says reaching for it herself. "look at it!"
"His prick is no bigger than my little brother's!" she says lifting the weighty globes.
Mr Derek can feel his heart racing and his skin burning up in shame as his manhood is being judged and criticised so harshly.
They tug and squeeze his genitals exploring their every contour and it's as if he can feel them shrinking back into his body.
"You see girls, this part of the anatomy will grow given some encouragement," Ms Charlesworth assertively grabs his penis.
She strokes it and the girls are mesmerised as his wagner thickens right before their eyes!
Mr Derek is horrified at their witnessing his arousal but he's utterly helpless to stop his dick from growing!
She stares at him possessively while handling his genitals thinking 'I own you, you big thick meathead!'
The girls stroke and caress him themselves. When they spied Chris getting himself off it was from a distance, but here they get to see an excited penis close up and feel how warm and alive it is!
She peels back the foreskin to observe the plump head of his penis like a present just for her.
His cock strains upward as if desperate for attention and their caresses.
"And when it grows like this does it stay that way forever?" Nicola wonders aloud.
Mr Derek bites his lip. He can already feel the cum churning in his balls and if these girls keep playing with his cock they'll see exactly what happens!
But, just at that moment, Chris reenters the classroom. Ms Charlesworth collects herself and clears her throat.
"That's best answered in Anatomy class girls!" she says as Chris stares in wonder at what's going on.
"Mr Derek, I think your class is over now don't you? I want you to come back in one hour. Got that?"
He nods submissively feeling so vulnerable standing before them all starkers and he immediately bows to her authority.
He grabs what remains of his clothes desperate to get dressed and escape their judgemental gazes!
"Come along now, just leave." Ms demands. "Don't dally!"
He feels his face burn as he clumsily covers his genitals with his clothes and opens the door.
He can hear the girls' laughter as he makes his hasty exit.
Chris is confused. What was going on here? Is that really what posing for bodybuilding involves?!
"I'm afraid Chris that you missed Mr Derek's lesson but you can stay and help with the anatomy class. I'll go get some equipment for the practical."
"He was totally getting a boner," Nicola says.
"You should have seen what we did to Mr Derek!"
He sneers at them and Kimberley taunts him, "We got the bastard naked and played with his cock!"
"I think you should be naked too! Ms Charlesworth isn't here. Strip naked before she comes back or I'll show her your wanking video."
Chris goes pale as a sheet! He's been so panicked wondering what will happen if the other girls at this school see his video he hasn't even thought of how much trouble he'll be in if a teacher sees he's been wanking in the gents!
He stands up and looks at the door nervously. He knows he has no choice but what if Ms comes back?!
He slowly takes off his jacket. Maybe he can draw this out and when Ms comes back in she'll over rule these wicked girls.
Nicola says, "You have ten seconds to get naked... or else!" He hesitates. Do they really mean it?
"Hurry up!" Kimberley says in a way that terrifies him.
He races to yank off his stupid shirt. All the while images of his family and friends all watching the video of him wanking flash through his mind.
He is in such a frantic rush he tears his clothes and simultaneously feels himself blushing furiously.
He drops his trousers and he's down to his Y-fronts. His heart is pounding a million times a second!
The girls glow with their power over him. "Every. Thing." Kimberley pronounces loud and clear.
Chris hears them count down "7... 8... 9..." and he's in a panic wondering whether to obey or try to call their bluff. Sweat has broken out all over his body and he's terrified what will happen if he doesn't whip his pants down right now!
PART 5: Chris is tempted to call the girls' bluff. Surely they'd never dare share that video they took of him wanking! But can he risk such shaming public exposure? They've given him an ultimatum: either pull his Y-fronts down immediately or everyone in this school will be watching him wanking like a shameless pervert! Chris doesn't know what to do!
As the girls count down, Chris dawdles and feels his heart pounding frantically.
"Now... or else..." Nicola demands.
Chris takes a deep breath and thinks 'Fuck it!' and slides down his pants...
He shields his cock and balls with his hands while wriggling them down...
He can't bear to look at their faces as he slides them off.
"What is THIS?" Kimberley says angrily.
Chris grimaces smugly. They said take everything off. Well, that's everything!
"I didn't think a WANKER would be so shy," Nicola laughs.
Chris shrinks against their gaze wishing he could completely cover his body. Being pushed into doing this is so humiliating!
"Move those hands," Kimberley demands.
She's seen him wanking from above but now she's starving to see that impressive package close up and in detail!
"NOW!" she says raising up a shoe.
She gives his knuckles a hard whack that makes him shudder and cry out.
Chris releases his penis and balls and to his utter embarrassment sees the girls staring directly at them!
Nicola is gobsmacked. His balls are HUGE! Especially compared to her teacher's Mr Derek. She thinks it's so funny that his testicles are so much more sizeable than the older more muscular man.
"This is the way you will remain all day!" Kimberley informs him.
"And I know how to keep him this way," Nicola says with a wicked grin.
She quickly gathers up his clothes.
Chris thinks 'No fucking way am I staying this way! Soon as I can I'll get dressed and tell on these bad girls.'
But Nicola rushes across the room carrying his clothes before he can stop her.
With absolute horror he sees her holding them up against the open window. She wouldn't dare...
He grimaces in horror watching them fall out the window!
Kimberley has such a satisfied grin seeing this naked boy so distressed!
Now that big meaty package will be on display for everyone to see!
"You're going to do what we say or we'll parade you naked in front of the whole school!"
Chris is furious! He has nothing else to negotiate with now. He's stark naked and they have an incriminating video of him!
The girls luxuriate in running their eyes up and down his fit body and admiring the heft of his genitals.
Just then, Ms Charlesworth enters the room again. Chris panics!
The girls think fast. "Stop it Chris! You pervert!" Kimberley shouts.
He stares at her baffled. What is she on about?
"You'll get into trouble," Nicola whines.
Ms Charlesworth looks him up and down seeing the boy is stark naked! "Chris Turner what are you doing?!"
"The girls made me do it Miss," he pleads pathetically.
"Made you strip naked? Don't tell tales. How could they make you do such a thing?"
"Chris wanted to show us he's muscly like Mr Derek," Kimberley says.
The teacher shakes her head and looks him up and down. Oh the arrogant pride of this young lad!
"He threw his clothes out the window," Nicola says innocently.
"He flashed his willy at us Miss!"
"And he says it's bigger than Mr Derek's!" Nicola adds.
Chris is speechless. It's all lies! But there's no way he can prove it. He's the one standing here starkers!
She has a look out the window and, sure enough, there his clothes are! What a filthy lad!
"His clothes are in a dirty puddle on the room of the science block."
She returns to the front of the room determined to make the best of this opportunity. "Well, Chris Turner, as you're so keen to be seen naked I'll use you in anatomy class..."
PART 6: Already flushed with excruciating embarrassment from standing naked before the girls, Chris' teacher now orders him to present his body for inspection and to be used as a prop for their education! He's always dreamed of having all eyes in the room on him in bodybuilding competitions but not with his wang and jewels hanging out for all to see!
Nicola mischievously leads the teacher on "Excuse me, Ms but are boys things usually so floppy?"
"Girls, you'll notice that the boys around you are going through many physical changes now and they will frequently get erections at the slightest provocation. Just have a feel and see..."
They reach out and stroke Chris' muscular thighs. So much more slender and boyish than Mr Derek!
Ms Charlesworth continues "At this age the boy's whole body is an erogenous zone!"
The way their fingers run up his bare legs makes him tingle all over. He wills with all his might not to get hard in front of them but he can't control his body!
"I think something's happening, Ms!" Nicola says excitedly.
"That's right girls," Ms says seriously looking down at him. "This boy has no self control."
His cock gradually inches upward and becomes thicker by the second.
Kimberley lifts his heavy sack. It's so weighty and full!
Nicola can't believe how large and silky smooth his nuts are!
Chris can feel his cock growing achingly hard and he wants more than anything for it to be stroked to give him release, but Nicola just pokes at it teasingly.
They test how by pushing it one way or another makes it bounce back and grow all the more stiff.
He can feel the teacher's eyes burning into him observing his complete and utter humiliation. He'll never be able to look her in the eyes in class again!
"Look at this pink part peeking out of the end!" Nicola says.
Chris is so ashamed! He can feel his balls churning and the way his cock begins to leak with precum with the desire to be stroked. No matter how hard he fights it he can't make this feeling stop!
Kimberley grips his balls and Nicola pushes his dick upward. Even having jerked off so recently, his prick is always ready. It's like he gets fifty boners a day!
"Look Ms! It's fully.... erect now!"
Kimberley feels a glowing sense of pride that they've teased this boy till he's powerfully stiff.
The girls giggle and exchange looks. "I don't know how boys walk around with these big things in their pants all day," Kimberley observes.
"It must get in the way so much!" Nicola agrees. "No wonder boys carry their books over their crotches between each class."
Kimberley tests stroking it up and down a few times and Chris shudders in pleasure.
"Oh he's shaking Ms! And look at how quiet he is now. Aroused boys are so tame!"
Chris wants to push them away, but at the same time he's desperate to get off - his cock feels ready to burst.
"Why are these so large Ms? Is it because they are full and need to be milked?"
"Yes, boys of Chris' age masturbate two or three times a day or they grow like melons. Disgusting!"
"I wonder what it feels like to have all that sperm build up," Nicola teases. "He must be very frustrated all the time."
"Precisely. It's why boys need constant discipline and strict control."
"This part of Chris' prick looks like it's been rubbed recently," Nicola says leaning in to see how pink his shaft is.
Chris blanches in embarrassment. He doesn't want Ms to know that he wanks in the toilets. He'll be in so much trouble if this comes out!
"I think it would be a good idea to stop handling his penis for the time being," Ms Charlesworth says. "Up on the table."
Trembling in fear, Chris climbs on the table. He can feel his arse naturally part and his big heavy sack dangling between his strong thighs.
"Now girls, this is very advanced. But I'm going to show you a part of boys' bodies not often covered in anatomy."
The girls gaze in wonder and lust at the big pale twin globes of his arse.
Chris clenches his sphincter and trembles as the teacher takes his cheeks in hand and spreads them.
"Have a close look girls. You'll notice that there is not just the penis and testicles, but a private area on a boy's body here..."
"Take your time and explore girls..." they eagerly prod at his nuts. They love how vulnerable his genitals look hanging down like ripe fruit.
Chris is nearly breathless. This has gone way too far but he has no idea how to stop it!
Kimberley's finger slides up his taint to that pink slit between his buttocks.
She rubs her finger around the edges of it feeling how wrinkled and strange it is!
"What do boys do with this?" Kimberley asks in fascination. Chris is utterly terrified and frozen in place!
PART 7: Ms Charlesworth has ordered the humiliated naked boy to climb up on the desk and present his arse to them. Chris is burning with shame but can see no alternative that won't result in him being expelled from school and branded a pervert. When he joined this bodybuilding class all he wanted to do was flaunt his muscles - not his ass!
Blushing deeply and desperately trying to hold his tears back, Chris bends over on the desk as instructed.
Ms Charlesworth holds his arse open and the girls examine with wonder the pink ring of his anus. Chris is terrified as no one has ever seen or touched this intimate part of his body before!
"This is a boy's sphincter," Ms instructs. "Have a look and feel girls. It's an area of the body that is in some way more sensitive than a boy's willy."
Chris feels a crushing humiliation as the girls examine him closer and he recalls those exploratory times he's spent in the shower washing his bum. He ran his finger around the circumference of his arsehole and the tingling feeling it gave him.
"It looks so tight, Miss!" Nicola observes. "It's all closed up!"
"Do you reckon I could fit a finger inside it?" Kimberley whispers to her friend as they gaze in amazement at it.
Chris' head throbs in panic. He doesn't want anything up his bum! Ever!
"You must be taught a lesson, young man," Ms says feeling empowered and excited by the thought of seeing this boy penetrated.
"Go on and slide your finger inside," Ms instructs and Kimberley experimentally feels the rubbery texture of his anus.
Just feeling the tip of her finger pushing inside him makes all the muscles in his body seize up and scrunch his face in disgust!
Nicola eagerly reaches under to handle his massive balls while Kimberley slides her way inside him.
She pushes and pushes! It's like his bumhole is a tightly locked barrier, but she's determined to get inside him.
Ms Charlesworth grasps his arse and goads her on to push through, "Well done! Keep going!"
Chris pants and twists his body against this persistent intrusion, but the teacher holds him firmly in place.
He feels her finger plunge all the way in and he lets out a mighty enraged howl!
The girls feel so massively turned on and empowered pushing their way inside him, fingerfucking this arrogant prick.
They hold him in place while Kimberley slides her finger in and out. Chris continues to cry and buck against them.
"Honestly Chris, pipe down and hold still!" Ms admonishes him.
Kimberley is entranced sliding her finger in and out feeling like she has total control of him. She'll show this dumb boy who's boss! Chris cries out "No!"
"If you don't shut your mouth and take it we'll have to do this in front of the whole school!" Ms warns him.
Kimberley can feel the tight entrance begin to loosen as the muscle is gradually stretched open.
Chris wants to plead with them to stop or call for help, but he does everything he can to hold in his cries of anguish.
Nicola toughly tugs on his willy hanging uselessly between his legs while his arse gets widened. She thinks how he looks like some kind of farmyard beast!
"You'll find there's an area up inside a man's anus called the g-spot. Wicked perverted boys like this find it a place of great stimulation!" Ms instructs them.
Kimberley feels even more enthused and aroused hearing this and plunges her finger in.
She explores how the tender flesh there yields to her.
"I think I'm getting it Ms!" Kimberley says. "He certainly seems excited," Nicola observes.
"Argh!" Chris grits his teeth feeling tense and gets hot all over as he feels his body is manipulated.
"I can feel his cock growing!" Nicola pipes up excitedly. "Maybe we should turn him over so we can see better?"
Chris can feel his cock growing engorged and hot. He doesn't want to admit that bum play has caused him to grow a stiffy!
"On your back, Christopher. This instant!" Ms orders.
He turns over feeling his cumbersome genitals flopping down as he does so.
He considers making a dash from the room and hiding his shame, but he feels like his whole naked body is now under these girls' control!
"Lay back and spread your legs," Ms orders and Chris complies. Kimberley eagerly goes back in using two fingers this time!
"It's opening even wider!" Nicola says in amazement. "How many fingers do you think we can fit up there!"
Kimberly rams her fingers inside him enjoying that she can now see his face while she penetrates him.
Chris grunts and strains to hold his cries in. He feels his arse yield to her as he's overcome with the sensation of being fucked.
He pants and moans while she wildly rams inside him and Nicola holds his arse fully open.
"Look at how big he's growing!" she says in amazement handling his engorged cock.
She strokes his thick penis while Kimberley slides her fingers all the way in, getting off on the fact she's causing him to grow uncontrollably aroused!
PART 8: Ms Charlesworth and the girls think Chris looks especially sexy flat on his back with his big gonads hanging between his legs and his pink virgin arsehole on show. It makes them ravenous and dare to utterly defile him right here in the middle of the classroom!
Chris is astonished by the shocking feeling of the girl's fingers sliding up his bum while Nicola strokes his thickening cock!
He huffs and moans feeling his genitals being totally manipulated. The girls are incredibly proud of the effect they are having on him.
Ms Charlesworth stares down authoritatively surveying this filthy boy's total defilement.
He groans as he feels his massive balls tightening up as the urge to cum is consuming him and there's nothing he can do to stop it.
"The filthy wanker is getting off on this, Ms!" Nicola hisses feeling his cock pulse in her hand.
Chris swallows and stares guiltily up at his teacher. He's covered in shame and embarrassment that he can't control his body's reaction to their treatment, but he can't help it!
Kimberley rams her fingers deep inside him feeling such a hot sensation of overpowering this boy.
He tips his head back moaning powerfully as his cock twitches in response.
"Now we're going to tell everyone in school how Chris likes it up the bum!" Kimberley says stretching his sphincter.
"That's quite enough," Ms says seeing that Chris has been driven to a frenzy.
"Off that table immediately and stand up straight, you filthy boy!"
Humiliated, Chris crawls off the desk. His naked limbs are trembling and he can still feel his cock pulsing!
He knows there is no coming back from the complete and utter shame of this. All the lads on the football team will mock him for getting off on taking it up the arse!
Nicola eyes him up and down thinking 'I fucking own you now!'
The headmistress tuts while looking down at his still engorged willy. What a shameless boy!
He's groaning and rubbing his sore bum when the door suddenly opens.
Mr Derek enters and is shocked to see his pupil standing in the middle of the class buck naked!
"Mr Derek. You're just in time!" Ms Charlesworth declares with a look that chills him to the bone.
He looks at the students wondering frantically what's been happening. 'Is that boy erect?' he wonders.
"Come over here and undress. I want the girls to compare your penis to a schoolboy's."
Chris winces in embarrassment and Mr Derek sees from the stern expression on her face that he better obey or else he'll be out of a job.
He nervously undoes his buttons. When the girls see him fumbling they race over to assist him.
What a treat! Not only do they get one over on hunky Chris, but now they can actually compare him to their big muscular teacher!
Mr Derek wants to shout at these girls to stop hurriedly disrobing him, but he recalls what the headmistress said about getting the girls involved and keeps an embarrassed silence while they strip him.
Chris looks down at his willy suddenly feeling very nervous about how it will compare to his big buff teacher's!
Both men feel very insecure about being compared to each other and possibly being the target of the girls' ridicule as they examine their penises next to each other.
"Stand next to each other where the girls can clearly see," Ms orders sternly.
The men quickly glance at each other's dicks while the girls gratefully take in the full view!
"Oh Miss, look at this!" Nicola says excitedly. "Mr Derek's is an entirely different shape from the boy's!"
"See how it's thicker and more... mature," she observes sliding her fingers around his shaft and tugging on his foreskin.
Kimberley tugs on Chris' dick while staring at her teachers feeling so overwhelmed and excited by this comparison.
"And the balls are so much more compact," she adds stroking her teacher's testicles.
"Weird, innit?" Nicola says. "You'd think the more muscular one would have the bigger testicles!"
Chris feels his cock pulse as the girls put it under such scrutiny against his teacher's. This is unbearably humiliating!
"What about the 'glans'?" Nicola wonders.
They slide back the men's foreskins delighting in how they are unveiling this most private hidden part of a man's body and seeing how they compare.
"The glans are the same size," Kimberley says. "But the balls... Chris' balls are ginormous compared to Mr Derek's. No wonder the filthy wanker must tug himself off in the gents' toilet."
"Yes girls, you see what an overactive sex drive does to a man," Ms says strutting around the men and assessing them against each other.
"Are men equally sized when they are... you know... hard?" Kimberley asks the Headmistress.
"An excellent question girls..." Ms replies standing very close to Mr Derek. The men are blushing fiercely and feel their bodies tingle all over as they feel the girls' desire for them both.
PART 9: Just a few minutes having a stealthy wank in the boys' toilet has led Chris on a spiralling journey to this utterly humiliating moment. He blushes fiercely as he stands naked next to Mr Derek while the girls and Headmistress asses how their muscles and cock sizes compare. He's never felt so self-conscious in all his life and he doesn't know how he'll live with this embarrassment.
Feverishly wanting to know how the two men's erections compare to each other the girls eagerly stroke the men's cocks. With their heads hanging in utter shame they feel themselves growing aroused against their will.
The Headmistress reaches down to testingly shake Chris' penis and says "It's at the semi-engorged stage. Perhaps play with the boy's balls."
Kimberley enthusiastically strokes and grips Chris' enormous testicles.
She's totally mesmerized by his big meaty balls and how his dick pulses in her hand in reaction to her teasing them.
She stands up and Chris is incredibly conscious of glancing down at his erection in assessment as if he's taking some test and being closely assessed.
Nicola eagerly reaches for his cock. Ever since she spied the look of ecstasy on his face while she and Kimberley caught him masturbating she's wanted to try to produce that same feeling by stroking him herself!
"Do all boys get erections so fast?" Nicola asks. "Certainly boys Chris' age do," Ms Charlesworth informs the girls.
"This one needs more encouragement," Kimberley observes tugging on Mr Derek's cock.
Nicola thinks it's so funny how the boy with only a thin amount of muscle now has a penis so much larger than the big meaty adult man's!
She rubs and strokes it many different ways but it's not nearly as stiff as Chris' giant boner!
Perhaps if she tickles his testicles she'll figure out how to excite her teacher more...
Ms Charlesworth surmises that she might have to modify this lesson while the girls continue to explore.
"Mr Derek, if you're not going to fully cooperate I will have to use you in some other capacity."
Nicola hopes she's not about to send him out of the room. Fondling the men side by side is the biggest thrill of her life!
"It's come to my attention this boy has been secretly wanking in the boys' facilities. You should have been watching out for this deviant behaviour. As punishment I want you to watch exactly what happens when this boy's penis is overly excited!"
Nicola grins feeling a perverse curiosity overcome her while she continues to tease Chris' genitals.
"On your knees and face Chris!" Ms Charlesworth orders.
Mr Derek humbly does so, trembling all over. In the locker room he's careful to look away when other men are undressing. Now he has to stare directly at one!<br />"Kneel in front of him!" the Headmistress demands.
He crouches right in front of the boy, the lad's engorged penis just inches from his face!
He studies how the pink glans and piss slit rapidly appear and disappear beneath the boy's foreskin as Nicola strokes his shaft. This is far more humiliating than just displaying his own naked body!
"Don't you dare move!" Ms Charlesworth demands while the girls continue to rapidly stroke Chris' penis and tease his balls.
Chris can feel that familiar tingling excitement made all the more powerful from these pretty girls' attention.
The girls are so thrilled and turned on bringing this boy off with big Mr Derek right in front of his penis!
"Keep you eyes on him!" Ms Charlesworth demands pushing him forward.
His heart is pounding and he feels himself blush fiercely with the boy's engorged cock nearly slapping him in the face!
"His penis is throbbing so hotly!" Kimberley observes stroking Chris.
Chris is totally overwhelmed! He thrusts his hips feeling the ecstatic pleasure running through his whole body.
He gasps breathlessly while his cock is frantically pumped.
Chris moans loudly and Mr Derek cringes beneath him.
Chris and the girls watch in utter amazement as his cum sprays out with terrific power.
It flies out and lands all over Mr Derek's bare face and shoulders!
They watch with supreme satisfaction and pleasure as the big burly teacher is drenched!
They continue stroking as wave upon wave of pearly spunk land all over his skin and hair.
"See now, Mr Derek! You've utterly failed to teach your boys self-control!" Ms Charlesworth chastises him.
"And don't you dare wipe this boy's mess off! I want you to walk around with his sperm drying on you for the rest of the day."
The girls erupt with laughter and delight seeing the male teacher covered in sperm. None of the other girls at school will believe what just happened!
Mr Derek shivers in shame seeing the drops of sperm drip down his naked body while Chris blanches in embarrassment about what he's done.
As the male teacher stands to leave, Ms Charlesworth stops him, "Oh your punishment isn't finished yet!"
"Get on your back and raise your legs," the Headmistress demands. The girls observe him obey with curiosity.
"Given that boy's shameful lack of self-control we weren't able to complete our lesson earlier, were we girls? I will now show you something very special..."
PART 10: The big muscular teacher feels his total exposure and vulnerability before these girls even more now that he's flat on his back with his arse unprotected. He becomes powerfully aware of how low and pathetic he is compared to them. These mysterious feminine women look down at him as if he's a sexual beast that needs to be controlled and tamed under their expert control.
Mr Derek nervously pulls his legs apart as Ms Charlesworth commanded. "I'm going to teach you something completely new..." she declares to the girls.
"There are tricks you can use to encourage a man's stimulation..."
The girls peer curiously at the dildo she takes off the shelf while Mr Derek waits in terror.
"You see how Mr Derek's arsehole is completely exposed. Try using this on him, Kimberley..."
The eager girl feels a sense of tremendous power taking the dildo and staring down at the big stud's vulnerable opening.
"Will this really fit in that little hole?" she giggles.
"Absolutely," Ms Charlesworth says confidently but Mr Derek panics and can't see how it will ever fit!
She confidently directs it toward his sphincter while Nicola and Ms Charlesworth eagerly watch on.
Just feeling that big blunt instrument touching his sphincter he trembles in terror.
She guides it in, pushing and opening his hole.
The more nervous Mr Derek gets the more he clenches his arsehole and the more Kimberley has to ram it inside him.
He yelps and strains as his tender arsehole is invaded much to the women's delight.
"Guide it in and the sphincter will eventually open," the headmistress instructs her.
Kimberley is thrilled to have this power over such a big tough man.
She thrills seeing the dildo slide inside him centimetre by centimetre. Meanwhile, Ms Charlesworth relishes the look of anguish on his face while he's penetrated for the first time.
Gradually she pushes it all the way up to the hilt and then begins fucking him with it.
She goes slowly at first and then builds up rhythm and speed.
"You're now pressing against an area up inside him called the prostate," Ms Charlesworth explains.
"This is his g-spot. Men find it irresistible to have this stimulated."
Mr Derek flails in anguish having his most intimate bits being manipulated. "Control yourself!" the headmistress demands.
Nicola takes his dick in hand while Kimberley continues to pound his arse.
"We're going to make you spill your semen whether you want to or not!" the headmistress tells him.
He feels lightheaded and overwhelmed as his genitals are so confidently taken under control.
"Take it, Mr Derek! You're mine now! Take it all!" Kimberley says feverishly while fucking him.
She pushes it all the way in deep inside him.
Nicola is thrilled glancing at the look of desperation on his face.
He's never felt so invaded and aroused all at once.
Kimberley is mesmerised by how his arsehole has opened wider while she slides the dildo in and out.
"You can see how helpless he is now, the filthy animal" Ms Charlesworth sneers.
He moans feeling his prostate manipulated and that familiar tingling in his balls, but more powerful than he's ever felt before.
She stares down at him thrilled they're able to completely control this big hulking beast.
Kimberley pushes the dildo all the way in and steadily nudges it in to increase the pressure.
At the same time, Nicola insistently pumps his cock.
He writhes naked on the table overcome by the way these girls have completely taken control of his genitals.
The sensation of Nicola stroking him and the dildo that fills his arse pressing insistently against his prostate...
It leads him to groan loudly...
And he feels an explosion out of his cock as his torso is bathed in his warm semen.
"You filthy man!" Ms Charlesworth chides him. "Flaunting your muscular body in competitions when all you want to do is release your sperm while women watch you! Shameless!"
He lays back utterly humiliated while Nicola eagerly snaps pictures! This is the most amazing sight she's ever seen and she wants to remember it forever.
She can't believe the amount of incriminating photos of the boy and male teacher she's accumulated today! Once she uploads them to social media they'll get a billion likes and shares!
"Please... you won't tell anyone about this... will you?" Mr Derek begs.
"Not if you don't report to class every day for a full bodybuilding demonstration followed by a milking session," the headmistress says sternly. "I want every girl in this school to learn how to regularly drain your balls!"
