Biology, 101

By William W. Kelso

Kathy had hoped the new school would be better then the last, but those hopes were soon dashed. It was always the same it seemed; no matter where she was some other girl would always find a reason to make her life miserable. She just didn't understand, she was certainly no threat to the local pecking order; her stout chubby body with its way-too large breasts had no chance against the athletic perfectly proportioned crowd, but they still picked on her anyway. They seemed to delight in making her life a living Hell, especially for their leader. And speaking of the devil, here she came.

Kathy tried to ignore the beautiful blond girl as she walked down the hall, but the other girl would have none of that.

"Oh look, it's the local bull dyke." Tiffany said to her friends, her small constant band of sycophants giggling as expected. "Don't you ever have those things milked?" More giggles. "I mean, I've seen udders on cows smaller then your tits." Giggles. Hee-hee-titter-titter-der.

Kathy just ignored the insults, though she felt like saying, 'What's the matter Tiffany, can't you come up with anything new, or would that strain your miniscule mind too much?' But she knew better, and buried her head in her locker. That was until the door suddenly slammed painfully against her. With a cry she straightened up, to find Tiffany only a few inches away from her face, and gasped as the blond girl grabbed one of her tits and gave it a hard squeeze.

"I was talking to you little Miss Slut," Tiffany snarled, a smile still on her face.

"Why don't you leave me alone?!" Kathy blurted, horrified to find she was almost crying from the pain and degradation.

"Oh, I just want to have a friendly little chat, girl to girl." Tiffany said, "You see, those straight A's you keep getting are screwing up the grade curve in half my classes, and that's not fair. I want you to back off and make maybe, oh, say a 'C' at the best, that should help bring the rest of us up to a passing grade, and you still pass too. Now, isn't that fairer for everybody?"

"I-I...can't do that!" Kathy exclaimed in horror, "I'm trying to get accepted to UCLA! I need good grades for that, and I can't go unless I get a scholarship!"

Tiffany could have cared less, daddy would make sure she got into any college or university she wanted, but bad grades would make that a little harder, so she said, "I don't give a shit what you want little Miss Cock-sucker, if you screw it for the rest of us, well, you have NO idea what will happen."

Kathy felt her blood run cold, "A-are you threatening me?" She stammered.

"Oh, not at all, that's against the rules!" Tiffany laughed, "I'm just telling you that certain...friends of mine would be rather upset, and I don't know if I can control them, you see. Now, I'm running late for cheerleader practice, so just you remember what I had to say. Bye!"

Kathy watched the girl and her friends walk away as if nothing had happened; rubbing her sore breast, and felt a cold hatred for the pretty 'perfect' girl. Head cheerleader, leader of the Glee Club, regular fuck of the jocks, and the school's pride and joy. Little Miss Perfect, and a complete and utter BITCH! How she got such good grades when she attended classes maybe once a week was living proof of the set of double standards for the privileged vs the less fortunate; and Kathy knew she was one of those. And the Hell she was going to blow her chances of getting into a good university just to make little Miss Perfect happy. She was no brain, but worked her tail off for good grades, she EARNED them. Fuck you, she thought as she watched Tiffany parading down the hallway, the peasants all groveling as she walked by. Fuck you, you bitch.

Kathy walked home instead of riding the bus; she was less likely to be bullied that way. Tiffany was not the only one who picked in the dumpy ugly girl, and Kathy didn't mind the long walk if she could avoid some unpleasantness. She hated her body, nothing about it was 'cute', and no boy had ever given her a second glance. Many girls would have liked to have breasts as large as hers, but she hated the damn things. Her heavy duty bras struggled to keep the DD cups restrained, and were horribly uncomfortable to wear. If they'd been more saggy it might have been better, but despite their size they were firm and jutting. She had no waist to speak of, her waist merging into her too-large butt so it was almost impossible to tell where one ended and the other began. She wasn't so much fat as built like a tree trunk, a tree trunk with huge tits. If only she was a little taller.

Reaching her house Kathy let herself in; mom wouldn't be back from work until much later, and fixing herself a rather small dinner she settled down to study for the next days biology exam. No matter how little she ate she just couldn't seem to slim down, it was so unfair. She had been studying diligently for the exam for weeks, and was sure she'd ace it. The teacher was strict; but fair, and was one of the few who dared to give the prima-donnas and 'privileged few' the grades they deserved. As she studied she would pause to remember every now and then, her thoughts distracted.

She had only lived her about a year and a half, her mother having moved them...again. They never seemed to stay in one place more then a two-three years at the most, then her mom would get bored and move on hoping to find 'greener pastures', whatever the Hell that meant. For Kathy it just meant more shit to step in. Of course sometimes it was because of some of the weird things that had happened, not that she ever blamed her ugly duckling daughter. Not that Kathy didn't love her mom; she did, with all her heart, but because of the frequent moves she never really had a chance to make any real friends. But she had grown used to being lonely, the outsider. Even other outsider cliques like the Goths and 'Lezbo's' wouldn't have anything to do with her. Fine, fuck them. She had no idea who her father had been, and doubted her mom did either. Her mother liked the boys; a lot, and had the good looks that had passed her dumpy little daughter by, so she never had any trouble finding a new boyfriend to share her bed until she got tired of him. Kathy didn't really mind though, as long as it make mom happy. She was used to hearing the sounds of lovemaking coming from her mom's room late into the evenings. She just wished she could get a boyfriend or two as well. She enjoyed sex too; at least with herself, and didn't count herself as a virgin anymore even though she'd lost her 'virginity' to a well used dildo. As far as being a Lesbian, she just wasn't sure. But so far as having sex with a living partner hadn't happened; male or female, and she figured her chances weren't all that good anyway. With a sign she put up one of the biology books, and cracked the next one. This was a mid-term, and an important one.

As she started to study again her mind wandered again and she gave a sad sigh. She was used to being picked on and bullied; she had been ever since she could remember. She had learned long ago not to complain, that would just make it worse. Her mom had no power or influence, so couldn't protect her. By just ignoring; or at least pretending to, she found she could live with it as the perpetrators would eventually lose interest. Except for Tiffany, for some reason the socialite seemed to have a personal grudge against her, and went out of her way to make Kathy's life more miserable then it already was. She was by far the worst of all the antagonists on the long list of those who had tormented Kathy over the years. It ranged from the usual poor jokes and insults, to outright physical harm. Last year Tiffany had pushed Kathy down a flight of stairs resulting in a broken arm, and then had sent her a "Get Well' card with the note 'Better watch your step, clumsy!'. When Kathy finally complained for once all the 'witnesses' had claimed she'd just 'tripped', and Tiffany had doubled her efforts to 'get even' with Kathy for 'ratting' on her. Everyone knew about it, but no one cared. She was just the fat ugly girl, so who gave a shit what happened to her?? Since then she'd kept her mouth shut, but it didn't do any good.

As she had expected Kathy got an 'A+' on her test the next day, the teacher even adding an 'Exceptional' under the grade. Kathy was thrilled, that guaranteed her an 'A' for the course, so it was smooth sailing from there on. She was so happy she completely forgot about Tiffany's threat, but Tiffany hadn't.

Tiffany was livid when she got a 'D+' on the test, if not for that ugly little toad of a girl she would have slipped by with a 'C' for sure. Well, it was time that little bitch learned her place, and she knew just the persons to help her. And sure enough, it didn't take much persuasion at all, not after she explained what she wanted. It would be so much fun, and teach that fat little slug her place.

Kathy's last class of the day was gym, the one class she utterly failed at, but still managed to get a 'C' through sheer determination. After the workout they all went to the locker room to shower and clean up, and as usual she waited until all the other girls had finished. She was horribly shy about being naked, even in front of other girls her age. So she waited until she had the whole locker room to herself, or so she thought. It was exactly what Tiffany had been waiting for, she knew the little freaks routine. This time she'd have 'company' in the shower. Tiffany made sure only she and Kathy were still in the locker room, then beckoning she waited until three people joined her, and gently shut the door and locked it. Now they'd have some peace and privacy, the gym was vacant now, the school closed for the weekend. Plenty of time.

Taking her clothes off and neatly folding them on the bench, Kathy went into the shower and turned on the water, and when it was just right she started to lather herself, the water running over her head masking the sounds as four figures joined her in the steamy room. When a voice suddenly said, "Hi Kathy, want some company?" she gave a loud squeal, and turning around froze in horror.

Tiffany smiled as the chubby girl saw the three boys with her, all of them naked, and very much aroused. She was naked too; she didn't want to get her clothes wet. She loved the way her body looked compared to the fat girl's; it was like comparing Aphrodite to a fat sow.

Kathy stared in growing horror as the three naked boys began to slowly approach her, their penises all erect and rampant. She tried to cover herself, holding one hand over her sex, the other being totally inadequate to cover her large breasts. She backed up against the shower wall, and stammered,

"G-Get out...!" Kathy squealed.

"Aw, don't be so antisocial," Tiffany cooed, "We just want to show you a good time is all, right boys?"

"Never fucked me a dyke before." A boy named Tod said. Like the other two he was on the football team, and had once been one of Tiffany's numerous 'studs'. He never turned down a chance for pussy though, with anyone. Willing, or...otherwise. Being a football hero he'd gotten away with outright date rape more than once.

"Never fucked me a virgin before," said the boy named Bruce, "so I'm going first, you guys can have sloppy seconds."

"P-Please...No-No...don't...!" Kathy squealed as the third boy; named Josh, gripped one of her arms and held it, then Tod grabbed her other arm, and they held her while Bruce and Tiffany 'examined' her.

"Not bad tits," Bruce said, "and look at that muff, looks like a jungle in there, can't even see her pussy."

"It's in there somewhere," Tiffany said as she squatted down, and reaching up she pushed wet matted pubic hair out of the way as Kathy struggled uselessly, and said "A-HA!" as she spread Kathy's labial lips, "Found it! She's got a nice big pussy!"

"S-Stop..." Kathy begged as she struggled frantically, "Please, I-I've never...STOP!!!"

"Good, she IS a virgin," Bruce said, "and I get to pop her cherry! Hold her still already, she's wriggling too much!"

Kathy struggled as best she could as they turned her around and tied her hands to the showerhead, the warm water blasting over her face and breasts.

"Damn it, hold her still!" Bruce said as he got in position behind her. "Hold her legs apart! Yeah, like that!"

Kathy opened her mouth to scream as she felt Bruce's cock probing between her legs, but as she took a deep breath a hand suddenly crammed a washrag into her mouth, and Tiffany said,

"There, that ought to keep the little lesbian quiet. This should be quite a thrill for her, having the shit fucked out of her by three studs. Be the first time she ever did it, with a guy anyway."

Kathy strained and writhed, then froze as Bruce's probing cock suddenly found, and then pushed into her pussy as he penetrated her. God, oh God, she thought. Gripping her tightly around the waist the boy began fucking her with a fast rhythm of powerful thrusts, grunting in pleasure.

"Nuuuu, ummggg, eeee-eeeee! Uhhhh Guddd!" Kathy squealed around the gag.

"UGH-UGH!" Bruce gasped, "She ain't no virgin, but her pussy is nice and tight! I'm going to enjoy this! Oh yeah! UGGHHH!"

Kathy screamed and shrilled through the rag in her mouth as Bruce humped her, the other boys holding her legs spread and steady as Tiffany rubbed up against her, tweaking and pinching her sensitive nipples, rubbing her own nude body against Kathy's.

"Mmmm," Tiffnay murmured in Kathy's ear, "Feels good, doesn't it? He'd got a great cock, really knows how to fuck a woman, doesn't he? That's it, squeal like a piggy! Oink, oink! And we're only just getting started, isn't that nice? Your very first gang-bang; and all these nice big cocks are just for you!"

Kathy closed her eyes, leaning her head against the tiles of the wall as Bruce began thrusting faster and faster, then she shuddered as she felt his cock pulse, and hot spurts of cum filled her sex. Oh God no, he just came, she thought in despair, and moaned into the gag. With a final grunt he pulled out of her, then his place was taken by the next boy, and she sobbed as another penis slid into her well lubed pussy and he began fucking her. Oh God, oh God... And to her further horror her body was beginning to respond to the pleasurable stimulation, no matter how she tried to resist, her vaginal muscles clenching around the hardness filling her as they tried to force out the intruder, or maybe suck the cock further in. She gave a groan as growing waves of intense pleasure radiated out from her abused pussy. No, nooo! I don't want to...to orgasm!! But as her peak crested and she climaxed Kathy gave a loud muffled squeal of unwanted pleasure through the gag in her mouth.

"Hey," Tod said as he fucked her, "I think she just came! She must really like my cock!"

"Told you see was a slut," Tiffany said as she squeezed Kathy's tits, "She's probably having the best time of her life right now, and Josh hasn't even had his turn yet. Yesss," she whispered into Kathy's ear, "Feels fantastic, doesn't it? Squeal, little piggy!" Kathy didn't respond, her eyes closed as the boy kept fucking her. And already she could feel that horrible unwanted pleasure peaking in her sex again. No, not again!!

The gang-rape went on for almost two hours, each boy taking a second turn as they fucked her nonstop. Except for muffled moans and groans Kathy was quiet, and had stopped struggling at some point, cooperating and spreading her legs to make the pounding her sex was taking even more...pleasurable. She helplessly gave in to her body as it betrayed her, and lost track of how many orgasms she had, which just made it even worse. Maybe it was the horror of the situation, or because it was her first time; but most likely a combination, but she had orgasm after orgasm, many more then her rapist did. And each one made her rage at her ongoing violation grow; she in no way deserved this brutal assault on her body. Finally the last boy shuddered a final time, and then pulled his cock out of her overflowing sex.

"Man," Bruce said, "that was a great fuck!" The others agreed wholeheartedly, who'd have thought the fat little dyke had such great tits and a first class pussy? Tiffany laughed, and said,

"OK, if you're through get the fuck out of here. I'll clean things up, and explain things to our little lezbo here."

At first Kathy thought Tiffany had left too, then squealed through the gag a she suddenly felt something cold and metallic feeling shoved into her pussy, then her squeal became even louder as cold water suddenly blasted into her sex, and she writhed and gyrated, her tits bouncing as her abused pussy clenched around the invader. Looking down she saw Tiffany squatting next to her, thrusting the end of a hose between Kathy's legs.

"This ought to clean you out good." Tiffany said, blasting Kathy's pussy with cold water as she washed it off, both inside and out. Helplessly Kathy spread her legs as wide a possible to make it hurt less, sobbing into the gag. It hurt, it hurt!

When all evidence of the huge amounts of cum that had been blasted into Kathy's pussy had been washed away Tiffany pulled the hose out, and standing up she whispered into Kathy's ear, rubbing her tits against the fat girls back while she brutally fondled Kathy's own breasts.

"I told you there would be consequences if you fucked up the grade curve, because of you we all got lousy grades, so figured you needed to make up for it. I wouldn't try to go to the authorities if I were you. Who are they going to believe, a fat little toad like you, or four upstanding young citizens from prominent families? Besides, I've washed all the 'evidence' out of you. And next time you fuck up our grades, I'll bring SIX boys. We'll take you out in the woods somewhere, stake you out, and they'll fuck your brains out. Got that, you tub of fat?"

Kathy just nodded, and said nothing as Tiffany pulled the drool soaked rag out of her mouth, and when Tiffany untied the ropes she just slumped down on the floor, the now cold water flowing over her naked body. When she finally stirred Tiffany was long gone.

In a daze Kathy cleaned herself up; feeling soiled no matter how she scrubbed, and slowly walked home. When she got home her mother wasn't there, so she went to her mother's room instead of studying at the kitchen table as she usually did. Reaching under her mother's bed she pulled out a very old hand carved chest, and opening it took out a much older book. She could sense the magic in it as she held it. Her mother had the power too, and had told her to never touch the book without her being there to instruct her, but this time she didn't care. She quickly found what she was looking for. It would be so...easy. Hopefully her mother would never find out, but she always had before.

Kathy went to school the next day, but other then walking a little slower because her abused pussy was so sore there didn't seem to be anything different about her. She froze for a second as Tiffany called out, 'Hiya dyke, you look tired, have a long night?', then kept walking and just ignored the laughing girl.

One duty every student got stuck with was staying after school about once a month to help clean up the biology classroom and lab to get them ready for the next days activities. There were usually two students assigned to the 'bullshit' duty, and as 'luck' would have it both Tiffany and Kathy had duty that evening. As usual Tiffany just sat and read a romance novel; or called her friends on her cell-phone, while the other student did all the work. No one dared complain. As soon as she and Kathy were alone, Tiffany started tormenting her as usual. It wasn't physical this time, but it still helped to make Kathy more determined to do what she had in mind.

"Hey there lezbo," Tiffany said, "what's it like to do it with a man for change? Or do you prefer tongue? I could have them eat your pussy first if there's a next time, if you like. Or are you going to behave yourself, and be a good little DUMB fat toad?"

Kathy just ignored the gloating girl, and after awhile Tiffany lost interest and began to read a book. After awhile Kathy went to the door; and Tiffany said,

"Where the fuck to do think you're going? You still need to get those tables cleaned off, and put out the buckets of frogs for tomorrows class, you stupid little toad. I sure as Hell aren't going anywhere near those nasty slimy things!"

"I'm just getting a drink." Kathy said deferentially.

"Oh, good idea dweeb, bring me a diet coke." Tiffany said; she made no move to give Kathy any money. If she didn't have enough for both of them, too fucking bad.

Kathy looked around as she put the two cans of soda on the break room table, then quickly tapped the contents of a small envelope of powder into the diet coke can. Holding her finger over the opening she shook it a little, and then carried the cans back to the biology lab.

"Bout time," Tiffany complained, "thought you're run off to the gym to see if the boys were waiting for you." Taking the can of pop she took a long drink, and added, "Man, this tastes flat!" But she kept drinking it. Kathy just smiled as she kept cleaning the tables.

Tiffany kept drinking the soda; it tasted better now, as she read her book. She ignored the first few pangs in her stomach as it gurgled; attributing them to the fact she hadn't had dinner yet. But then a really strong cramp made her bend over, and she gave an "Umff!" of discomfort. Man; that was some bad gas! What had she eaten to cause that?? Damn cafeteria food!

Kathy ignored the other girl's increasing discomfort, and kept working. Sorting through the buckets of living frogs scheduled to be used in tomorrows class she took some out of one bucket and put them in another, and vice versa.

Tiffany bent over and burped, but it did little to ease the bloated feeling in her guts, and with every breath if felt like her stomach was swelling, her already tight skirt getting even tighter to the point it was painful. She felt hot and cold at the same time, her whole body aching, a thick slimy sweat oozing from her pores, and feeling something brushing against her neck she reached up and found herself holding a handful of hair, long blond hair. Oh shit, she realized, my hair is falling out!! What the fuck?? Then she looked at the hand holding the hair, blinked, looked closer, and gave a loud squeal. Her fingers!! The tips were swelling, and they had...had SKIN growing between them!! And the tops were turning GREEN! With a little shriek she stood up, and weaving unsteadily saw Kathy locking the door to the lab.

"Kathy, what are you doing??" Tiffany grunted as her guts churned again, "I'm sick; we have to get to the nurses office! I think I ate something bad!"

"Oh, I don't think so," Kathy said quietly, "everyone else has gone home by now anyway, it will be just the two of us. Besides, she couldn't help anyway. No one can."

Tiffany sat back down as her belly suddenly churned as it swelled again, and one of her leather pumps slid off one of her expanding feet, much too long toes pushing through her stocking, green toes connected by webs of skin. With a soft 'pop' one of the buttons on her shirt gave way as her expanding breasts pushed it beyond its limits. Though well endowed, her breasts were now fast approaching Kathy's in size, her bra barely able to contain the swelling mounds of soft flesh.

"Oh, ooohhh God." Tiffany gurgled as her head began flattening, her mouth widening, lips hardening, "W-what's happening to me, grunt, I feel so...so strange." Reaching up to touch her head with her still changing hands she moaned as it came away with another large clump of hair that stuck to her slimy green skin. "N-Nooooo! What's, urrppp, happening to meeee?!? Kathy, help me! Urrgggle!"

"Don't fight it," Kathy said, "it will hurt less that way. Just let it happen."

"Let WHAT happen? Greeep!?" Tiffany said, and then clapped her hands over her mouth. Had she just...croaked?!?

"Why, changing into a frog," Kathy said. "You know, Kingdom Animalia, phylum Chordata, class Amphibia, order Anura, in short, a Leopard frog. A big, fat, slimy, frog."

With a squeal Tiffany lurched to her feet, and stood swaying unsteadily. The sudden movement caused the last buttons on her shirt to pop off, and as it opened her bra gave up the fight, and two huge pale green sagging breasts spilled out, large green nipple jutting, rigid and sensitive. Tiffany kicked off her last shoe, giving a grunt of relief as her new toes unfolded from the uncomfortable position the shoe had held them in, and then started to stagger towards the door. But she didn't get very far.

"Uh, uh, uh, I don't think so." Kathy said from where she was sitting on a lab stool with her legs crossed.

Tiffany squealed as her legs suddenly cramped violently, and collapsed under her. With an "oaffff!" she sat down, her legs folding underneath her leaving her in a crouching position. With a desperate 'BREEEP!' she tried to get up, but was tangled in clothes that were finally getting loose again, but they stuck to her struggling body, drenched with the slimy mucus her slick darkening skin was oozing, darker stripes and spots spreading. Slowly she disappeared from view as her still changing body shrank, and shrank. "K-Kathy, greeep, h-help me, ple-ribbit-ease! CROOAAKK!"

Kathy waited a few more minutes, then stood up and walked over to the pile of damp sticky clothing, a small bulge squirming in the center. Lifting away a couple of layers she grabbed the large Leopard Frog before it could try and get away, and holding it up she looked at the desperately struggling amphibian, it's throat pulsing, bulging eyes staring back at her expressionlessly. The last changes were taking effect as she watched, the frog's large breasts shrinking to bumps, then the nipples to spots, before disappearing entirely leaving nothing human remaining except for the intelligence in its bulging staring eyes.

"Hello Tiffany," Kathy said with a smile, "looks like you fucked up by messing with a witch, didn't you? I can put up with a lot of shit; but after last night, well, that was the last straw. I hope you like the new you, it's quite an improvement in my opinion."

The frog kicked frantically, squirming, then seemed to give up, hanging limply in her hand. It began making gurgling squeaking sounds intermingled with peeps and grunts, and Kathy knew it was trying to talk.

"Don't bother trying to talk," Kathy said, "your mind might be human, but your body is a frog's now, no vocal cords. Now let's get you settled in for the night, I've got a nice bucket of warm water ready for you. And you'll have company."

The frog kicked its powerful legs a few times as Kathy walked over to the shelf holding the plastic buckets of frogs, and with a soft 'plop' she dropped the frog into one. It had about a dozen other frantic frogs in it along with a few inches of warm green tinted water. The new frog was larger then any of the others.

"There you go," Kathy said, "nice, isn't it?" The other frogs quickly noticed the new arrival, and some of them began to show intent...interest.

"Oh," Kathy said, "I thought you'd like to know, the other frogs are all males, and since this is breeding season, well, I'm sure you'll have a busy night."

Kathy smiled as she watched the males pursuing; and fighting over, the frantic female as she hopped around the crowded bucket in a desperate effort to avoid them , but soon one of them managed to get on her back and grasped her tightly despite her best efforts to dislodge him, and she was helpless as they began mating, the female giving loud pleading peeps and croaks as she gave in to the inevitable, the amorous male rubbing and stimulating her.

"Well, Tiffany," Kathy said, "I sure hope you enjoy being gang-banged by a dozen sex starved frogs, and I'm sure you'll lay lots of eggs. And by the way, once the first one cums inside of you the change is permanent. See you in the morning, good night. Have fun!"

As Kathy finished cleaning up and got ready to leave; being sure to put all of Tiffany's nasty soiled clothing in a plastic bag; she'd dispose of it later, she smiled as the loud croaks and chirps coming from the bucket suddenly peaked, and then faded before starting up again. One down, eleven to go. With a smile she turned off the lights as she left. The only sounds in the lab were frantic croaks, and splashing coming from one of the buckets.

Kathy was relieved her first class the next morning was Biology 101. She came in early to help prep the tables and get them ready for the days lesson, how to perform a vivisection on a living frog. Of course she made sure she got Tiffany, having to pry a desperately mating male off her back, large amounts of eggs floating in the bucket.

"Hi Tiffany," Kathy said, "did you have a fun night? From the looks of all those eggs you were really busy. Guess you didn't get much sleep, did you? Well, this will help you wake up."

The frog struggled and kicked desperately as Kathy took it over to her table. Her lab partner was a nerdy little boy named Kevin, who might have had a chance with her if he wasn't so horribly shy and introverted. While he held the frog down Kathy firmly pinned its legs to the board with thick pins, using a little hammer to make sure they wouldn't come loose. The frog squirmed helplessly, fingers and toes clenching, throat pulsing, as she drove pins through its wrists as well, and Kathy stroked its slick clammy stomach fondly. Then she picked up the scalpel as the teacher said,

"Now pay attention class, make the first incision...like so...being careful not to cut too deep, next..."

With a smile Kathy gently slid the scalpel down the frog's chest and stomach, the razor sharp blade penetrating and cutting the soft skin easily. The frog wriggled frantically, peeping shrilly, muscles bunching and straining uselessly against the pins. Then she made two crosswise incisions, and carefully peeled back and pinned the flaps of soft abdominal skin to expose the internal organs, the heart visible as it beat rapidly. "Enjoying yourself, Tiffany?" Kathy asked softly, Kevin eying her uncertainly. Kathy smiled at him, and said, "Just thought I'd give her a name."

"Your frog should still be alive if you've done the procedure correctly," the teacher said, "Now to determine the sex make an incision...like so. If the frog is male you should see what passes for his penis, if not a female may have some eggs visible. Now we'll start to remove the various internal organs, starting with the stomach to see what our little friends had for dinner..."

Kathy carefully did as the teacher instructed; the frog shuddering but quiet now, and was surprised when the class ended, she'd been having SO much fun.

"Replace the organs and sew your frog up," the teacher said, "and put the body in the bucket in the corner. Study your diagrams and notes, and tomorrow there will be a test for extra credit. You all did very well."

Kathy sewed the frog shut, the one difference between her frog and the others being that it was still moving, squirming feebly. She told Kevin she'd take care of that little chore, and he'd already left. Holding up the 'reassembled' frog, she smiled viciously, and said,

"Well, that's over with Tiffany. You should be proud, you actually did some good for once in your life, helped teach something. Now don't worry, you won't die, you can't. That little spell I cast on you includes health and youth, for five hundred years. That's right, you'll be a nasty slimy disgusting frog for five hundred years; won't that be fun? And as for now," she added as she dropped the frog into one of buckets still containing live frogs; all males, "you'll be good as new by morning, just in time for the next vivisection class. Then after four more days of that fun and games I'll take you home with me and keep you in an aquarium. Don't worry, I'll make sure you have plenty of bugs to eat, and males to keep you company. You'll be in constant estrus, so they'll make sure you get well serviced, all the time. See you in a few days."

Kathy smiled as she left the class, the loud croaks and peeps of the doomed frogs; all but one, following her. She paused and checked three more packets of powder in her purse, labeled 'snake', 'lizard', and 'toad'. Hmm, she thought, which of her rapists would get the first one? Bruce, yeah, he'd make a nice snake. Then Josh, he'd make a good lizard; then Tod would become a nice big fat toad. She'd have to stop at the pet store and buy some more aquariums on the way home; she'd need the room for all her new 'pets'. Quite a few people had picked on her over the years, and the other aquariums were already full.

The End
