Practical Instruction by Anon [2012]

"Alright everyone, enough talk! We need to get started."

Despite the excitement in the room, the pre-class chatter died off almost instantly and 32 bright young faces swivelled towards Miss Tomoko. The boys and girls of Class 7 had been anticipating this day for months and now that it was here they weren't planning on missing a moment.

Miss Tomoko felt a shiver run down her spine and she quickly adjusted the pencil that was holding up her dark, ash brown hair and tweaked her dark rimmed glasses in the hopes it would hide her nervousness from her class. Although she hated to admit it, she'd been anticipating today almost as much as her class had been. 23 might have seemed a little young to retire but the payout would be excellent and her sister could really do with the cash for her new restaurant. Besides, there was worse ways to have your job terminated…and with Jim… Tomoko shivered again.

"Ok class", Tomoko began, "Now I know everyone's excited about today and we'll get started as soon as Mr. Porter and Ms. Klaassen makes it here but first I need to set some ground rules." She paused momentarily, ensuring she had every child's full attention and continued.

"Rule 1. You must pay close attention during the demonstrations today. You'll have plenty of time afterwards to try out what you've learnt but I really need you all to stay focussed when we're up here at the front as we won't be able to repeat things."

"Rule 2. Don't be afraid to ask questions at any time. We've lots of time so if you want to ask something raise your hand. If you think of a question later, Ms. Klaassen should be able to answer them for you." She saw a the eyes of a couple of the boys light up and had to stifle a smerk when she momentarily pictured what they'd be asking Tatiana Klaassen to help them with in about an hour.

"And finally, rule 3. Relax!" A few grins began to show in front of her. "Today's class can be pretty intimidating but it is also a lot of fun. Relax and make the most of it. Everyone will enjoy it all the more."

A knock on the door was followed by the entrance of Jim Porter and Tatiana Klaassen. Mr. Porter was the school science teacher these days but he took gym as well until last year. 38, a handsome face, always a smile, a wisp of grey at the temples and that slight outline of muscle under his polo shirt. Jim had caught the eyes of Tomoko when she first started here and she'd noticed he caught the eyes of a lot of female staff. And almost all of the female students.

Ms. Klaassen looked immaculate as always. Shoulder length red hair in the slightest of bob cuts, a tight white blouse with faint pinstripes served to at once highlight and demurely hide a bust that Tomoko would sometimes have given anything to possess and a dark grey wool pencil skirt outlined the rest of her curves. Tomoko thought she was in her early 30s but she didn't really know, sometimes Tatiana could play the stern elder lady of the school, sometimes she showed a playful streak that would have made her seem more at home in a uniform. She flashed Tomoko a cheeky grin for just a moment.

"And here's my help, right on time!" Tomoko clapped the exclamation, almost jumping for joy. No turning back now she thought.

Mr. Porter perched himself on one of the steel tables at the front of the class and Ms. Klaassen made her way to a spare desk right up the back of the class.

Tomoko turned, nodded at Jim and wrote one word in large letters on the blackboard, Anatomy. Tomoko squeezed her eyes shut tight, drew a somewhat ragged breath and held it for a moment. "Showtime" she thought.

"Children, Ji–Mr. Porter and I will be the adult models for today's class but -" she smiled as the suspicions of her class hit home bringing smiles and even the odd look of lust. Cindy in the front row had been staring at Mr. Porter since he walked in and Tomoko saw her squeeze her thighs together and ever so slightly tremble. "- but we also need two volunteers from the class. Everyone was given permission forms to take home and sign and I've made my choices."

There was a momentary murmor before Tomoko said "Bill. Could you come up front please." A quiet young man in the third row promptly went beet red.

Bill was always a quiet kid but he worked hard and had endeared himself somewhat to Tomoko. Normally that would have meant she wouldn't have singled him out to be pulled up in front of class to be poked and prodded but when she read the plee to be chosen he'd written on the back of his permission form she could hardly say no. Getting towards 5'8" already, lean and cute he'd make a good subject.

He was still staring at the floor as he shuffled past Tomoko. She subtly grabbed his hand and gave it a reassuring squeeze and was rewarded with a sheepish smile.

"And as the other subject, I've chosen Kirsten."

The reaction couldn't have been more different. Kirsten, a stunning, sharp featured and athletic young brunette who was just beginning to bloom into a seriously gorgeous young woman, stared Tomoko straight in the eyes, mouth open…and came. Hard. The ten fingers and white knuckles digging into her desk couldn't stop a couple of pens clattering to the floor and the class erupted in giggles.

"Hey!" Tomoko snapped "We're all excited here and I'm sure a few more of you will be doing that later." The class fell silent and Kirsten made her way to the front with a wet patch visible clear through her plaid skirt. Jenny, Kirsten's best friend ran a finger through the pool of liquid left on her classmate's seat and quietly sucked it clean.

"To begin, all of us subjects will be stripping so you can get a close look at us. Everyone scoot up as close to the front as possible, make sure you've got a clear view and get ready to take some notes."

With that Tomoko pulled the pencil out her hair, shook it out slightly and unzipped her skirt and shuffled it over hips. Before she could even bring her hands up to her blouse she could feel the warmth of the class as they all crowded to the front. After unbuttoning that she folded the blouse and skirt carefully on a chair, reached behind her back and, with just a touch of theatre, slowly let a bra fall away. She may not have had the biggest tits but she was fiercly proud of the two firm, upturned handfuls and the little, rapidly hardening, nipples that could cut glass in the heat of passion. She looked up to see every eye in the room fixed on her and blushed. Even Ms. Klaassen was transfixed from her vantage point at the back of the class and Tomoko noticed she had hitched her skirt up and was already massaging an impossibly pink little pussy whilst the classes attention was elsewhere. Panties, it would seem, didn't factor greatly into Tatiana's dresscode.

Finally Tomoko looked down and began to slide her own panties down of her hips revealing her pussy and it's little trimmed tuft of soft brown fur. She was grateful that they had remained dry. She was excited as hell but she also desperately wanted to show the class how a pussy responded to stimulation. She momentarily thought about her heels and stockings but decided to leave them figuring she was neither particularly tall nor would a pair of thigh high stockings interfere with anything planned for the class.

The sound of a couple of zippers made Tomoko's head jerk up and she glared at a couple of boys who had already pulled out their cocks and were stroking away gently. Mark had even enlisted the aid of Isobelle who's delicate little fingers where wrapped around the base of his prick.

"That's allowed" Tomoko growled "but make sure you don't lose your heads just yet. I need you all to pay attention."

Turning her attentions to Mr. Porter she noticed he'd already slipped his polo top over his head and she thought she'd grab the opportunity to help with his pants.

As she slipped her fingers under his belt Tomoko whispered "All good?"

"No problem, Tommi." came the reply as Jim dropped a hand onto her hip. "Looking forward to it."

The belt unfastened and Tomoko knelt as she slid Mr. Porter's jeans and boxers down as one, admiring the firm, lightly tanned chest and stomach inches away from her face as she went. As the pants dropped further Tomoko nearly squealed as Jim's cock was revealed inch by inch. Nearly 6 inches and he was still completely soft. This boded well for…well a couple of things really.

Jim stepped out of his pants as Tomoko stood up and, noticing that both Bill and Kirsten were still standing fully clothed and staring at the two teachers, she plonked her hands on her hips firmly knowing it would give her tits a nice jiggle and pursed her lips slightly.

"Now that will never do…" she jokingly corrected her two volunteers. "Jim, you help Kirsten. I'll do Bill."

Striding over to Bill she grabbed his shirt and noticed the poor kid was visibly trembling.

"You still want this don't you?" She asked.

A nod.

"Then try to relax, we'll go nice and slow."

Another nod.

Unbuttoning his shirt she quickly drapped it over a nearby chair and dropped to one knee to undo his pants. She noticed a tiny damp spot on the front of the fly and no sooner than she had undone the button and zip Tomoko found herself nearly slapped in the face by Bill's glistening, throbbing cock and a sack already drawn up close and twitching. At nearly 6.5" it was incredibly impressive for a boy so young and so hard that even though he was uncut, the foreskin was pulled back and almost taught. A bead of precum glistened on its head.

"I'm going to need to take care of that…" thought Tomoko.

Meanwhile a kneeling Mr. Porter had been helping Kirsten out of her blouse and he reached behind her to undo her bra. Leaning back he revealed a pert little pair of A cups with nipples the colour of cotton candy and an impossibly thin little waist.

Nervously, Kirsten rested a hand on Mr. Porter as he unzipped her blue plaid school skirt and let her step out of the damp garment. He smiled as he saw the state of Kirsten's panties and looked up at her reassuringly. She was soaked, her white cotton panties almost translucent and glued to her lips and a few trickles making their way a couple of inches down the inside of the girls milk white thighs. He ran a thumb over the front of them and Kirsten, who'd been passive until now, almost leapt out of her skin as a new stream emerged from under the left seam of her panties.

"Sir…" she half hissed, half moaned.

"Let's get you out of these." replied Jim and begun to tug the panties down. The gusset remained stuck firmly in place until the last possible moment until it peeled away revealing a perfect little innie, slick with Kirsten's excitement and trailing a few shimmering strands of it, and crowned by a tiny little triangle of the very faintest peach fuzz.

Tomoko glanced over and seeing the condition of Kirsten was as desperate as her own charge she figured they could add an extra activity.

"Kirsten. Bill. Hop up on the big desk here and we'll begin with a demonstration of human arousal and oral sex. Bill lie back on the desk and Kirsten, straddle him so you can suck his cock and Bill can lick your pussy."

"Class, as for Mr. Porter and I, we'll be demonstrating what happens as a person becomes aroused. Bill and Kirsten here are obviously already very excited so I'll need you to pay attention to two things at once."

Tomoko took a seat on one of the steel tables and spread her legs, Mr. Porter sat on the other and Bill and Kirsten were on the big wooden desk up front positively shivering with anticipation. The lab mirrors gave everyone a clear view of everything that was about to happen. Tomoko felt herself beginning to ooze.

"Ready?"

"Ready!" the class chimed. Mr. Porter nodded, still soft. His self control was admirable. Tatiana on the otherhand looked to be well on the way to her first orgasm of the day and squeezing one huge tit through her blouse, still completely undetected by Tomoko's transfixed class.

"Ok Kirsten and Bill. Do you two need any help?"

"No." Bill managed to gulp staring at the exquisite pussy Kirsten was presenting to him as she knelt over his face, back arched. Kirsten merely shook her head.

"Well, take it away." said Tomoko and immediately saw Mr. Porter's cock twitch in the corner of her vision.

Kirsten squatted down dropping her pussy on to Bill's open mouth and leaned forward to kiss the tip of his cock. Instantaneously she was rewarded with a fountain of cum as Bill's pent up urgency finally found its escape. Jerking back surprised she rasped her clit over Bill's tongue and joined him in ecstasy, flooding his mouth while rope after rope of his cum found a home on her little tits, her shoulders, a few even finding her face, mouth and hair.

"Well that was inevitable." murmured Tomoko before addressing the class.

"Well, that was a good example of a male and female orgasm. Note the force with which Bill's cum was ejaculated and the amount of fluid Kirsten produced. This is quite normal for two young, fit people who've been waiting on release for a while."

Tomoko reached down and dug two fingers between the lips of her own pussy and spread them for the class to see her own arousal.

"As you can see, this display is making us teachers quite turned on as well. My vagina is lubricating itself quite nicely and you'll notice that it's starting to flush a darker red colour. Mr. Porter is also getting quite har-" Tomoko gasped as she looked across at Jim and the 8" cock that pointed skyward from between his legs.

"Err…Mr. Porter is getting quite hard as well. Notice how his cock is getting thicker as well as longer?" Tomoko though it must have been as thick as her wrist by now.

"Don't stop!" groaned a desperate and still rockhard Bill and Kirsten quickly came to her senses, lent forward and began to slobber and suck on the head of Bill's cock as she ground her pussy into his frantic tongue.

Tomoko could smell Kirsten's pussy from where she sat and the stimulus made her gush a little. The boys who had their cocks out were now stroking faster and several of the girls had begun rocking themselves against the edges of chairs with a few of the more daring rubbing themselves through their panties. Isobelle on the other hand was pounding Mark's cock at a furious pace and he had reached a hand behind her as they stood and was clearly fingering her, the occasional telltale buckle of Isobelle's knees really giving the game away. At the back of the room, Tatiana, her legs now spread wide with her feet on nearby desks, pinched her clit and threw her head back in a silent orgasm. Tomoko felt herself gush again.

"Ahhh…like that Bill!" Kirsten gasped before diving down again on Bill's knob, one hand pulling his foreskin and balls back tight, the other flying up and down the bottom few inches of shaft in a blur.

"Yef…YEEEEEEFFF!" she mumbled around the cock as she began to shudder in another orgasm, Bill trying desperately not to be drowned as he suckled on her pussy.

"See how Bill's balls are becoming tight class? This mean he's about to cum." commented Tomoko and right on cue Bill groaned into Kirsten's cunt and unloaded into her mouth. Two of the masturbating boys and several of the girls joined the pair on stage. Isobelle finally buckled completely, falling back against Mark and screaming into the side of his neck as she came, a few telltale drops spattering on the floor between her legs. Mark meanwhile turned the chin of a young blonde called Jessica who'd been sitting in front of him open mouthed and slightly shellshocked at the scene up front. As soon as she was facing him Mark came, jets of cum hitting her in the eye and nose before the rest found its way to her mouth and chin. Tomoko would have chided Mark had it not been for the immediate reaction of Jessica to start swallowing his cum before slamming Mark's cock down her throat for the final few spurts.

Up on the desk, Kirsten continued to slowly stroke Bill's shaft for a few seconds before sitting back, a lazy smile on her face, and swallowed Bill's cum before wiping a few stray drops from the corners of her mouth.

"Mmmm…" she lazily exclaimed as Bill, finally, wilted.

"This might be a good time to begin the next part of the class." said Tomoko.

"We'll move onto the dissection now class. From here on out, we can't repeat anything so gather around and watch closely. I will be doing the dissection so that means Bill and Kirsten will go first, followed by Mr. Porter and finally I'll do myself. Then we can move onto sex-ed!"

Tomoko was amazed how excited she was by all this. She could hardly wait to begin cutting into these two kids and the delicious body of Jim but then she'd get to finally cut into herself. She'd rubbed herself raw thinking about that moment for months and it was almost here. Suddenly light-headed, Tomoko stood up on very rubbery knees and directed Bill to lay down on the steel table next to her as a trickle of her own juices rolled down her thigh.

A slightly flushed Ms. Klaassen emerged next to Tomoko with a bag containing the necessary tools and some syringes of vital drugs.

"Now we're not interested in pain response for this class, we covered that when we flayed Chrissie last term, so I'll be injecting us all with a pain blocker. It lets us still feel what's happening, only the brain doesn't interpret it as pain."

With that she carefully slid the needle into Bill's arm, emptied it's contents and turned to pick up a scalpel. As she turned back she was greeted by Bill's cock standing erect yet again and scowled at the boy.

"Sorry, Miss. It's just…well the view from here is great."

Bill did indeed have an excellent view of his favourite teachers firm tits and soft bush as she stood over him with the knife.

"Careful." she warned. "I'm armed." she added with a wink. "Shall we start?"

"Yes Miss."

"Ok class, watch carefully. I'll make a quick little incision just below the sternum here to check that the drug worked."

The blade of the scalpel sunk in to Bill's chest and as she drew it down, an inch of deep red followed it. Bill didn't even flinch. Well, to be more accurate, nothing except his cock flinched.

"Looks like it's working." Tomoko observed dryly.

Working quickly now, Tomoko drew the knife down until about an inch from the child's pelvis and began to make a Y incision just above the tops of his hips. She noted there was very little blood, a side effect of the pain blockers, and set the scalpel down.

"Ok class, I'm going to open up Bill's stomach now and remove everything that's unrelated to sexual function or necessary for life."

She reached her fingers into the vertical slit and peeled Bill's flesh back in two big flaps. A few gasps and a quick scan of the room revealed her class was watching every move and she quickly began to remove Bill's organ's one by one, noting each as she proceeded.

Within minutes Bill's lower abdomen was largely empty, save for a prostate and deferens and a few essential blood vessels. Tomoko noted that the Bill's cock, still hard and now leaking precum again, meant she'd missed all the important nerves as well.

"Ok, that's Bill done. I'll now point out the various organs."

After instructing the class on what went where she looked at a pleading Bill and smiled.

"I'll move onto Kirsten now, could someone quickly take care of Bill for me?"

"Me, Miss!"

Eleanor, curly brown hair bobbing like springs practically elbowed her way to the front and began to climb up onto the table.

"Well…ok" said Tomoko "but make sure you watch we're doing on the other table El. And don't wear him out, he's got another demonstration to do in a few minutes."

Eleanor nodded, straddled Bill, flipped her skirt up, hoiked her panties to one side and plunged herself down on Bill's cock until she hit bottom and came almost immediately. Coming down from her orgasm, she leant forward, took the his hands and kissed the evicerated boy deeply before sitting back, her uniform bloodied, to begin slowly riding the boy to his own orgasm whilst working one of his fingers in and out of her tight little asshole.
