PART 1: During geography class, good mates Chris and Ricky are fed up with the endless lectures and presentations. The boys chuckle and elbow each other imagining screwing their sexy nerd of a teacher Ms Bartholomew. But soon their attention shifts to hot classmate Evie and how her shapely legs show under her school uniform and skirt.

"It's time for some more presentations," Ms Bartholomew declares. "Evie I hope you've properly prepared."

"Your topic is a subject I find infinitely fascinating!"

Chris and Ricky chuckle. What could be so interesting about the shape of rivers? They're much more interested in the shape of Ms Bartholomew's tits!

Evie stands and clears her throat before beginning, "An ox-bow lake is a U-shaped lake that forms when a wide meander from the main stem of a river is cut off, creating a free-standing body of water..."

She hates having to stand before the class and knowing the boys are leering at her.

"Hey, dare you to snap a pic of her snatch," Ricky goads Chris.

"Just slide your phone under her skirt quickly..."

"This landform is so named for its distinctive curved shape, which resembles the bow pin of an oxbow," she drones on.

Chris can never resist a dare. He thinks about all the kudos he'll get from the other guys if he gets Evie's panties or her butt cheeks on camera!

He quickly slips his phone out of his pocket and opens the camera.

Sliding forward as quietly as possible he holds the phone under her skirt.

Ms Bartholomew is listening so intently to Evie she doesn't even notice.

He snaps picture after picture while trying to aim up her skirt.

"In Australia, an oxbow lake is called a billabong, from the indigenous Wiradjuri language. In south Texas, oxbows left by the Rio Grande are called resacas...." she continues obliviously and gets caught up on pronouncing the last word.

She can also hear the boys snickering behind her. She doesn't know if it's because of what she's saying or the shape of her bum.

"Good one man," Ricky laughs.

"One for the wank bank," Chris chuckles.

Evie struggles on, "The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream."

Chris knows he should wait till break to show it to the guys but he can't resist displaying his treasure to his friend right now.

Ricky snorts loudly seeing how he caught the outline of Evie's arse on camera.

Evie can barely get any more words out she's so self-conscious now that the boys are laughing uproariously.

Ms Bartholomew has had quite enough and marches up to the disruptive boys.

She casts them an intimidating glance. What on earth could be more interesting than what Evie is discussing?!

Ricky can't help himself. The look on her face makes him chuckle even more.

"What's so amusing? Chris, you know you're not supposed to have phones out in class!"

"Give it here," she demands.

She snatches it out of his hand before he can close down the pictures.

Ms Bartholomew is absolutely horrified by what she sees!

"This is appalling! How could you degrade Evie like this?!"

Chris is overcome with fear at being caught out but Ricky can't stop laughing.

Once the laughing bug takes hold of him there's nothing he can do to supress it.

And it makes Ms Bartholomew all the angrier hearing these boys not taking it seriously.

Chris has to use all his willpower not to laugh as well especially when Evie looks at him with such a stupid hurt expression.

He studies the top of his desk feeling the frightening presence of Ms Bartholomew hovering over him.

She grabs his ear and twists hard.

"You're going to the Head Teacher's office. This instant!" she informs him.

Evie's delighted this vicious little piss stain will finally get what he deserves.

"Can I come too, Ms? It'd make me feel so much better seeing Chris punished for what he's done to me!"

Ricky watches on feeling a stab of guilt that he's the one who caused all this.

In Ms Stern's office the Head Teacher addresses the delinquent lad, "Well Chris, I can't say I'm surprised to see you here, but I am disappointed. Now, what have you done this time?..."

PART 2: Evie's had it with these smug school boys' pervy behaviour! Luckily the teacher allowed her to accompany bad boy Chris to see the headmistress. She's going to savour watching him tremble under her gaze and she's hoping she'll maybe even get to see him caned. Ms Stern has been cracking down on boys' pervy behaviour lately and taking more extreme measures to stop it!

"Come now!" Ms Stern demands in her shrill voice. "What have you done this time, Christopher?"

"I erm... took some pictures," Chris mumbles. Ms Bartholomew instantly adds, "Up sweet young Evie's skirt!"

"Ah, I see... perving on girls again, are we?"

"You filthy young boys let your raging hormones control you. You NEED discipline!"

Chris cringes wishing he could be anywhere but here. Getting told off is SO embarrassing!

"I know what you're like. Sat at your desk all day... popping boners, masturbating in the boys' loo, sharing pornographic magazines. It's disgusting!"

"You don't respect your female classmates or their bodies. I doubt this is the first time you've stolen a look up girls' skirts."

"He spies on us through the window of the girls' changing room during PE," Evie hastily adds. "All the girls know he does it."

"He even took a video once and posted it on the internet," she continues making up an elaborate lie.

"Boys all over the world have seen us girls naked. It's upset me so much I don't dare get changed at school anymore."

"I'm almost too afraid and ashamed to come to school anymore. It's out of control," Evie adds close to tears.

"It's a big fat lie, Miss. None of that happened!"

"She's just trying to make me look bad. Honestly Miss!" He begs.

"Silence Christopher! You don't expect me to believe anything you say when you were caught red handed, do you?!" she thunders. "I've had it. You need a lesson you won't forget. I'm going to cane you. Now strip!"

Chris can't believe his ears. He's been caned before but always over his trousers.

But he sees from Ms Stern's furious expression he'd better obey.

With trembling hands he removes his jacket.

He frantically wonders how much he's expected to take off and screws up his lip indignantly.

Why should he have to strip off with his teacher and classmate watching? It's so humiliating!

"And the shirt," Ms Stern orders.

"You're going to feel exactly what my poor girls have felt when you infringed their privacy and their bodies!"

He can feel their eyes burning into him and Evie's satisfied grin.

The girl perks up excitedly at the sight of his smooth boyish body.

"Off with your trousers!" Ms Stern orders. "Immediately!"

His shaking fingers feel so clumsy. He can barely undo his belt buckle.

Chris' heart is racing and he feels himself break out all over in a cold sweat.

Evie's sniggering laughter rings in his ears as he peels down his trousers.

Ms Stern takes such delight in lording it over the stupid boy and making him give them a show.

She steals a look at his shapely bum in his tight white pants as he wrestles to get the legs off.

Chris is furious and fighting back tears as he stands before them with his prominent package pushing through his undies.

"Take it all off! Socks and pants," she says slapping the table impatiently.

He removes his socks while tottering in place feeling terrified he might fall over. His nerves are making him so unsteady!

"Are you trying to mock me, boy?! Moving at a snail's pace. I've had it!"

She sizes him up and launches toward him.

Chris freezes in place seeing the imposing furious headmistress approach him.

She seizes his arm and it feels like a shock shoots through his body at her touch.

"I see I need to take matters into my own hands," she says as he hangs his head in terror.

Quickly she snatches his pants and furiously yanks them down.

He catches his breath as he's aware of his penis and goolies suddenly hanging out in the open!

Ms Stern thrills at the sight of the boy suddenly standing before her stark bollock naked.

Chris is overwhelmed by a sensation of total panic! This is outrageous. But what can he do?!?

PART 3: Chris is outraged that Ms Stern has just stripped him of his tighty whities! It feels so wrong but what can he do with the double authority of his teacher and the head teacher demanding he take this punishment? This is so embarrassing - he wants to disappear totally - but all he can feel is their gaze alongside that of cheeky schoolgirl Evie.

As soon as his pants come down Chris grips his genitals as tightly as possible to hide them.

But Ms Bartholomew and Evie are behind him and can stare openly at his tight little arse! "Step out of those things!" Ms Stern demands.

He must obey! Evie giggles watching the globes of his arse go up and down while he gets the pants off completely.

Feeling like he's going to combust with shame he bends down to retrieve them aware his arse is pointing at the women while he does so.

He puts them away with hands trembling so hard wishing more than anything that he could dress again and escape.

He stands before them not knowing what will come next and fearing what Ms might order him to do now.

"I think we've a nice opportunity here," Ms Stern comments.

"Evie, you've not taken biology class yet have you? And since I know you'd never do anything perverted like peek in the boys' locker room you must have no understanding of the male anatomy."

"No Ms. I don't understand anything about how boys' bodies work," Evie says with faux innocence.

"Away with your hands, Chris. Stop obstructing the lesson," Ms Stern demands.

With a sharp slap of his hands he releases his genitals which fall back into view.

"It is a funny ugly thing," Evie comments.

"Why are his nipples all pointy?"

"They are rather erect," Ms Stern comments stroking his nipple. "When boys grow aroused their nipples harden as well as their willies."

"See if you can make it really hard," she suggests so Evie grips and twists his nipple hard.

"You see how firm it is now?"

"Now try the other one..."

Evie squeezes the pink bud between her fingers as hard as possible.

Chris winces wanting to cry from pain but mainly because he feels so agonizingly embarrassed.

"Now you'll see that his arms are different from girls."

She bends his arm making him flex his muscle. "See how large the bicep is."

"It is much larger than any girls' I've seen!" Evie comments feeling the bulge of it.

"Flex them both Chris. Show her properly," Ms Stern orders.

"Wow! It is impressive Ms! All that sport has really made them grow."

"See how much the triceps are developed as well," Ms Stern encourages her.

"Because of all that sport boys tend to be quite sweaty in this region."

"They are sweaty... and hairy!" Evie observes.

She pulls away suddenly, "Phew! They smell as well."

"Also observe how taut his stomach is," Ms Stern invites the girl.

"There is a bit of a six pack but other boys will have a more defined one," she adds.

"You will though notice how these lines around his torso curve down to his groin."

"It's like they're pointing to it," Evie observes laughing.

"I like that, Ms!" Evie chirps and Ms Stern prompts, "Now turn around young Chris."

"You'll also see how boys have more musculature in their buttocks."

"Have a good feel to see Evie," Ms Stern encourages her.

"It looks small but it's got some heft," Evie comments.

"It's firm too!" she enjoys sliding her hand over the curve of it.

"Now then, let's continue!" Ms Stern orders him while Ms Bartholomew is just enjoying the show from close range.

Chris feels his stomach twisting into knots. This scrutiny of his every feature is unbearable. He feels like he's going to explode from complete humiliation!

"You'll of course notice the main distinct difference between girls' and boys' bodies."

"These are the penis and testicles," she says triumphantly. "And do you know what they do?"

PART 4: Not only is Chris being treated to his own medicine, but the head teacher sees this as a unique opportunity for a lesson in the male anatomy. After all, there's only so much a girl can learn from a text book and diagrams. Far better to have the real life thing in front of her so she can really experience and understand how boys' bodies work.

Ms Stern points out the boy's penis and testicles to Evie, "Do you understand their function?" Chris shudders in terror.

"Not really," Evie observes his genitals. "But I never realised how big boys' bits are. How do they walk around with them all day?"

"You're quite right," Ms Stern agrees. "They are cumbersome. And you'll see that particularly when a young man grows aroused his penis is most obstructive!"

"Have a feel and get familiar with the penis and testicles," she invites the girl.

"See how the skin on his shaft moves back and forth..."

"What's that pink bit poking out there?" Evie asks curiously.

"Those are the glans," she explains as Chris fights the powerful excitement he feels swelling through his organ.

"Are the glans always meant to be covered?" she asks curiously.

"Well during arousal they will appear. But most of the time they will remain covered by the foreskin."

"I would hasten to add that not all boys have a foreskin," Ms Bartholomew adds.

"That's right," Ms Stern agrees. "Some boys have it snipped off when they are very young."

"That sounds painful, Ms!"

"I daresay they don't remember it. But you see here this one has his full foreskin," Ms Bartholomew says sliding the skin on his shaft back and forth.

"You'll notice it grows heavier the more the boy grows aroused."

"Already it is thickening up. This is because boys, especially boys at this age, have hormones raging through their whole bodies."

"That's why they are so driven by sex and it's all they think about. It brings out their worst animal natures and they become like insensible beasts."

"It does feel heavier already!" Evie says excitedly.

"Look how it's growing!" she observes.

"That's because his testicles are aching to be relieved of their sperm," Ms Stern explains.

"I see. So they're connected. But how does the sperm get out?" Evie asks. All the while, Chris feels increasingly light headed and humiliated.

"The boy must be stimulated to a point where he becomes so excited all the sperm comes rushing out of his penis."

Evie takes her time pawing around his genitals feeling their texture and weight feeling very aroused herself.

"It's because of this troublemaker right here that led to Chris' bad behaviour. He wants to use those photos taken beneath your skirt as masturbation material!"

Ms Stern squeezes his balls so he winces in pain. "But he must learn that girls must not be meddled with in this way!"

"I see why he's done it now," Evie says. "But I think he should still be punished."

"Quite right! Chris there are disciplinary measures in place to deal with your pervy behaviour."

"What you need young man, is a good old fashioned caning."

"Now clear my desk so you can bend over it completely!" she orders.

With trembling hands he picks up the objects on her desk.

It feels so hugely unfair that he's being humiliated above and beyond what he did to this stupid girl.

The room is eerily quiet as he moves the objects and the women all stare intensely at him making him even more aware of his total nudity and impending punishment.

If it wasn't for his friend Ricky he wouldn't have dared to take the pictures and he wouldn't have got into this mess. It's all so unfair!!!

Ms Stern pulls out her trusty cane. This instrument has lashed droves of young men's buttocks over the years.

"Stop fussing and delaying your punishment," Ms Stern warns him.

"Now bend over that desk!"

Chris obeys but feels sick to his stomach this is so embarrassing.

The imperious head teacher admires his smooth buttock. A sense of thrill and excitement rushes through her - being in this position of absolute power.

"I believe in justice and discipline," she says to the terrified young man.

"That's why I don't think it's right that I cane you."

For a second, Chris feels a wonderful sense of relief. This was all meant to just scare him! Now he'll be able to dress and get away!

Ms Stern gazes at her cane knowing exactly the sort of excruciating pain it can cause landing on a boy's bare buttock.

"Here you are Evie," Ms Stern says handing her the cane and causing Chris to feel a fresh sense of panic. "You were the one who suffered his prank. You should be the one to deliver his punishment!"

PART 5: Chris is already close to tears with the embarrassment of standing before all the commanding women naked while they examined and felt his bits! Now his humiliation will be amplified even further with a dose of corporal punishment dished out by the girl he so thoughtlessly mocked.

Ms Stern demands: "Bend over that desk and stay there, young man!"

"I'll hold him in place Evie," she says while clutching his penis. "You give him a good hard whack!"

Brimming with excitement, Evie swings hard hitting him right on his big pale round arse cheeks.

Chris winces and lets out a puppy-like yelp!

He arrogantly thought a little cane couldn't hurt but it stings so much!

Ms Stern feels a hot thrill when the boy shudders in pain while she clutches his silky penis.

Evie targets his arse again amazed she's getting to whack this bully right on his smooth boy's bum.

Chris clenches his fists not wanting to show any weakness or pain but he's unable to stop his body from shuddering at the agonizing sting of it.

Evie works herself into a frenzy hitting him harder and with more confidence.

Each satisfying whoosh of the cane and cry from the boy makes her hungrier to discipline him.

Not only is the pain intense and intimate, but Chris is flushed with humiliation.

Evie is proud of the angry pink lines she's leaving on his pristine arse cheeks.

She wants his arse to hurt for a month! She wants to see him wince every time he sits in class and know it's because of her!

Ms Stern and Ms Bartholomew are impressed by this girl's technique. "Well done Evie!"

Chris' heart is pounding in panic and he's sweating all over from the physical strain and acute embarrassment.

"I could keep going Ms!" Evie says hopefully.

"Now Evie, you've done a fine job. But I think Chris also deserves a firmer hand."

Chris rubs his sore bottom in agony. How can a caning be any worse than that?!

His arse stings so painfully and he wants so desperately to get dressed and run home.

"Hold him tight, Evie," Ms Stern commands so that Evie grasps his penis. "Now bend over young man and don't rise until I tell you to!"

Trembling all over with terror, Chris does so and Ms Stern relishes taking aim on his already painfully sore bottom.

She draws back her cane and sends it wooshing through the air with tremendous power.

SNAP! It hits his arse and Chris is filled with an explosion of pain.

While he's still reeling Ms Stern aims again.

This time the cane snaps against his bottom crossways making him feel the pain all across his buttock.

The women laugh and delight seeing him wriggle in pain desperate to get away.

Ms Stern is an expert in disciplining boys having caned their bare bottoms for many years.

Chris pants tearfully and desperately pleads, "Please Ms! I'm sorry Ms! It'll never happen again!"

She puts the cane back feeling supremely confident in her ultimate authority. She really knows how to let boys have it!

"You bet it won't happen again, young man."

"You may rise now. And you're going to let all your wicked buddies know they'll receive exactly the same punishment if they pull that sort of prank."

Standing up, Chris is conscious that not only is his arse incredibly sore, but his dick has sprung up while clutched in Evie's hand.

"What is going on there young man? What are you covering up?" Ms Stern thunders in accusation.

She smacks his arms making Chris release his tumescent cock.

"You filthy little bugger! Ladies! Come look at this!"

They all stare at his thickening penis and grin.

"You've been lying to us. You haven't learned a thing, have you boy?" Ms Stern accuses him. "Get down on your hands and knees. NOW!"

Chris instantly obeys feeling a horrible guilt. He can't help how his penis reacts!

He hangs his head miserably wishing he could control his weak body, but it's like his dick has a mind of its own.

Tears run down Chris' cheeks while Ms Stern pronounces, "I see we need to take extreme measures to teach you a lesson."

PART 6: From the moment he stepped into her office Ms Stern could see by the look on this boy's face what a dirty pervert he really is. Now it's been confirmed by the way this lad grows a hard on because of their punishment. There's really only one thing to do to enable Chris to stay in school without having a perpetual hard on!

As Ms Stern commands, Chris gets on all fours so the women can gleefully inspect his hindquarters.

"You see sometimes spanking boys who are especially horny like this one can have the unintended consequence of stimulating their glands," Ms Stern explains.

"There's a particularly sensitive one up boy's bottoms right here," she says prodding his sphincter.

Chris grimaces in shock as her finger slides up his bum!

Ms Bartholomew and Evie are amazed and aroused seeing this boy's virgin arse being penetrated!

"You never thought you could do this, did you Evie?" she says to the girl. "I'll show you how to really control a boy's sex drive."

Chris feels waves of sensation going through his body and an acute embarrassment being treated like a wicked animal.

"You twist your finger up like this..."

"And thrust right up into the boy's rectum to press your finger against his prostate."

Chris can't help letting out a moan. He's never felt something like this before!

"You see how the wicked boy responds," Ms Stern says with satisfaction. "He must have very full balls," Evie observes.

"Here we are," she presses in further. "This will drive the bugger wild!"

Ms Bartholomew must firmly hold him in place because Chris begins to buck wildly under the intense stimulation.

He wills himself to remain calm but can't control himself from getting more aroused even while he feels so wretchedly embarrassed.

"I think I can see his penis growing more," Evie observes.

"Let me see," she says reaching under and grasping his penis.

"It is Ms!" she says excitedly. "It's getting very firm!"

She naughtily strokes it causing him to grow an even firmer hard on.

Chris clenches his stomach and tries to resist but the need for release is overwhelming.

"I reckon if you keep up he's going to make a big mess," Evie laughs.

"That may be for the best," Ms Stern explains. "Boys can't concentrate and behave while having full balls."

Evie thrills at feeling how hot and alive his penis feels in her grasp and how his pleasure is totally reliant on her.

"That's it young man. I see you're utterly hopeless and won't be able to return to class until we've dealt with this."

He rises up and looks guiltily down at his aching hard prick.

Evie feels so turned on and proud that she's caused him to be so aroused.

"Evie, have you ever seen a man ejaculate?" Ms Stern enquires.

"Oh no, Ms. Only diagrams in my texts books. The girls and I always wondered what it really looks like."

"Well this is the perfect opportunity," Ms Stern says glad that this business of discipline will also have an educational benefit.

"You see how his penis is throbbing with life at the moment," she says making them all stare down at his guilty erection.

"This is how boys walk around all day. They've got these big unsatisfied penises swinging in their trousers."

"Only once they've satisfied themselves will they be any use at all."

"Now Chris, I want you to ejaculate for us to stop this nonsense. Stroke your penis."

He grasps his penis feeling how hot and bothered it is. He's covered in shame while they watch him.

"We're going to observe you and Evie will tell all her little friends what it looks like," Ms Stern continues.

Chris wants to weep in absolute embarrassment while stroking himself.

At the same time his dick comes angrily to life and he can feel his balls churning with the aching need to cum.

Even while he gives himself pleasure he can't stop the urge of wanting to hide his penis from these observant women.

Evie gets closer to him, wrapping her arms around his shoulders and he can feel her warm feminine body against his naked body.

"I can see better from here," she says teasingly.

Chris doesn't know if he can go through with this. It's too much pressure!

He's fantasied about getting off with the other girls in his class and his teacher. But now he's here and naked he's consumed with a self consciousness so strong he's close to panic. At the same time he wants to get off so badly!

PART 7: Chris only meant taking a picture of Evie's panties as a harmless prank. Something for his wank bank as well as a reason to give his buddy Ricky a laugh. But it's landed him in a situation he never could have imagined in his worst embarrassing nightmares. Here he is stark naked being ordered to jerk off while his classmate Evie, his teacher and the head of the school watch him shamelessly pleasure himself!

Chris squats on the floor stroking his penis while nervously scanning around to see the attentive faces of his teacher and Evie.

Ms Stern feels a magnificent sense of power and feels very aroused having this sexy athletic boy under her full control.

"Do you often stroke yourself while thinking of me?" Evie enquires wrapping her arms around him.

"If only there were surveillance cameras in the boys' loos I know we'd catch you all tugging away thinking about your female classmates," Ms Stern tuts.

Chris hangs his head guiltily while inhaling the rich feminine fragrance of Evie pressed up against him.

He feels his dick twitching in his hand while the sense of total debasement and embarrassment shudders through his body.

"I want you to help me," Ms Stern says to Evie. "Keep a watch for any boys getting stiff in their trousers. It's a sign they are about to commit an act of perversion and ought to be reported to me immediately."

"Oh I will Ms. My friends and I will all watch the boys trousers for any sign of tenting."

"Even in my office here I can hear them popping boners all day long!"

"I'll keep a special eye on you," she says leaning over Chris.

"You won't ever get an erection again without me knowing!" she promises.

Chris allows the thought to fill his mind: living under complete sexual control of this mischievous girl. It's an arousing idea!

Ms Bartholomew leans in as she's very aware of this issue as well. She notices so many of the boys staring at her cleavage and then shifting their text books to cover their trousers.

Ms Stern presses in closer studying his growing penis.

"You'll be my personal wanker boy!" she whispers.

He feels like some kind of animal senselessly tugging himself, totally helpless to control his overriding sex drive when surrounded by such arousing women!
