The Experiment

#3 of Celestine Preparatory School for Gifted Girls

Helga has a theory about what is happening to her. But she needs some help. Her friend Ilyana might be convinced to lend a hand.


It wasn't much, at first. After being trapped by Jennifer, she wasn't even sure it was true and not just a figment of her imagination. It's not like she ever measured herself. Being around statuesque goddesses all day waving around baseball bats with balls to match, she didn't need to know HOW tiny she was. All she knew was that when she slipped into her uniform after cleaning herself up after her encounter in the stall, it seemed like she had a tiny bulge noticeable even though she wasn't hard at all.

She felt shame and anger after Jennifer's blackmail session but deep down she also felt like it met some kind of need she didn't know she had. Like she had gotten some vital nutrient she didn't know she was missing. Normally she, like all gifted girls, needed to relieve herself at least a couple times a day but she wanted to try something. She had gone two days so far and she felt so full she was distracted in class. She didn't want to wait longer than that because Ms. Feliz always said it was important not to get too backed up. Plus, she was watching Helga like a hawk, like she had taken a special interest in the mousegirl and her scholarship status. It was sweet, but Helga had a mystery to solve.

She had gym next and that's where she was going to test out her theory. After changing into her gym clothes and grabbing her water bottle she stopped by the water fountain and opened it up as if to fill it. She was the last one to head out towards the gym and once everyone was out of sight, she dumped out the bit of water she had poured out and screwed the clear bottle closed. It was the biggest one she could buy, holding 64 ounces and it had a handle it was so big. She looked at herself in the mirror and nodded, adjusting her glasses and looking herself over.

Most of the girls wore a lighter fabric version of the skirt that was part of their uniform because they just couldn't fit themselves into gym shorts. A couple people that were smaller managed to just barely cram into them, the fabric straining obscenely. Helga thought it was just so they could show off what they had. She wore the shorts because for at least a little while, nobody could directly see how small she was, not that all didn't know. She did strain the shorts in her own way, her wide ass having ripped more than a couple pairs this semester. They all wore sports bras that cinched their chests down along with the soft velcro straps they had to strap their cocks and balls in place to make it better for running. Helga didn't need the latter and the former compressed her massive tits down until they looked more like hard bowling balls then her usual fluffy soft chest.

Once all the girls were gone she followed behind and walked right into a brick wall that was definitely not there before. She rubbed her nose, wondering if she had done more than bruise it but a hand on her shoulder caused her to look up into the golden eyes of Mrs. Oyawale, the gym teacher. The lion was pure muscle, but not bulky like a power lifter. She wore a tanktop and, despite being a teacher at Celestine, she was one of the only non-gifted females. Generally speaking, owing to the risk of an incident occurring, females were completely off limits at the campus. Until the gifted girls learned to control themselves, their extremely high potency was just too great a factor.

Mrs. Oyawale was married to the headmistress though and, while some thought it was nepotism that got her the job, she was also a retired professional kickboxer and had proven herself with a couple overly handsy students once while visiting her wife. That and she seemed to really care about her job.

"Miss Swerter, how's that ankle?" The lioness asked her, looking her over, "I don't want you going from a sprain to a break."

"Oh, uhm...it's still a little sore." Helga did get bruised up pretty bad after her run-in with Jennifer the other day and needed an excuse that seemed plausible. She was known to be a little clumsy, so she thought a slip on a wet floor would be good enough.

"Allright. Give it another couple days. Go sit in the bleachers and rest." She swatted Helga on her ass and shooed her into the gym, causing her to yelp a little bit. She quickened her pace, heading in and taking a seat at the very edge of the bleachers, on the bottom row. After some sharp whistles from Mrs. Oyawale all the girls gathered together and were ordered to run laps for the first few minutes.

Helga certainly had her fair share of bullies at Celestine, and most of the girls were just white noise to her since they didn't pay any attention to her, good or bad. She did have a couple girls she was friends with, or at least cordial with. The most stand-out of those was one of the other plump girls, Ilyana. Ilyana was short like Helga and she had decent tits and ass, but what made her stand out was that she was built like a fireplug. She was on the wrestling team and was undefeated, but she seemed to never really train very hard. Right now she was more powerwalking than she was running. None of the girls bothered her though, not because she would fight them, but because it never seemed to bother her. It helped that her family was royalty as well.

Ilyana was a pig, calm and quiet, and they had hung out a few times. Helga had seen her get poked fun at but she never even acknowledged it. The other big reason the popular kids left her alone was that while her cock was legendary. Unlike some species of pig, it wasn't a corkscrew but it was tapered and twisted. Maybe if she could straighten it out she would be longer, but that wasn't what made it so well known. She had a special pass where she could skip entire classes to relieve herself because when she came, it took her almost a half hour to finish. Her fat nuts hung low even strapped in place and maybe it was just Helga's imagination but she thought even from the bleachers she could hear them sloshing.

Helga waited for her moment. All the girls were running in a circle, getting yelled at with a mix of encouragement and derision from the gym teacher, as tradition dictates, when she caught eyes with Ilyana. Helga nodded slowly, making sure the pig saw it. As the slower girl brought up the back of the pack, distance widening every moment, she stopped at the gym teacher's side and pulled out her card to show the lioness. Another nod from the teacher and she trotted back down to the locker room and, once she knew she wasn't seen, she snuck out behind her friend.

Once they were down in the locker room, Ilyana saw down on a bench and grunted a bit, unstrapping herself and tossing aside her skirt, "Ok, what's this about. If you want me to fuck you or something, you know I only like dudes." She leaned back a bit and sighed, her heavy balls hanging low, sweat running down them to drip on the floor and mix with the thin stream of pre that was already running free from her twisted length. The musk was overpowering already and Helga thought it must be the most potent seed in the whole school. It was perfect.

"No, I know. I wouldn't ask you. I'm still a virgin..." She thought back to Jennifer making her suck her off in the stall and wondered briefly if that counted. "...that way. I..uh...I need your cum."

The pig had already started stroking herself, the fat length rising to the occaison slowly. She had to show her hall pass, she wasn't going to waste it. "What?" and she stopped for a moment, "....what?"

Helga chewed her bottom lip for a moment, trying to decide if she she explain it or keep it a secret, lest her friend thought she was crazy. She's probably have to explain the whole face-fucking incident then and she didn't want to get in more trouble with Jennifer than she already was. Any day she was going to probably corner her in a stall again and she wanted to try her experiment before that happened. "I...I promise I will tell you why later, but if you help me now I will help you with your language studies. You're falling behind in German, right? It's my first language. Please, Ily?"

"Alright, but you better have a good explanation." She went back to stroking herself, her cock now fully erect and drooling pre like a river. The smell was even stronger now, the whole locker room reeking of the pigs growing needs. "Bend over and let me see your assholw though. You might not be a boy but I can imagine." Helga squeaked a little in embarrassment at the candidness of her friend, though she shouldn't have been surprised. Ilyana was crude and rough and had no real filter. She needed that cum if she was going to test her theory.

She unscrewed the top of her big nalgene water bottle and placed it between her legs, bending forward and sliding her shorts down over her fat ass, stopping just before she would show off her pussy, She reached back and held the waistband in place and pulled herself wide for her friend to look at.

Ilyana didn't bat an eye at the strangeness of the situation, already stroking herself faster. Helga found herself wondering if everyone at the school had the hair trigger she did, but it seemed like her friend was just getting into it. "Fuck yeah, that's a nice fuckin' ass you got there. Shame you ain't my type." She reached out with her free hand and slapped it, making that cheek wiggle and the mousegirl to squeak again.

Helga held still, feeling shame at her position, at exposing herself to her friend, but just like the awful situation before, she felt herself growing aroused. Hidden under her shorts, her small cock was growing hard as well and she could feel a dribble of her feminine juices rolling down the back of her balls to collect in the liner of her shorts. Behind her, unseen, she heard the grunts, moans, and wet squelching noises of Ilyana jerking herself faster. It seemed like forever in her mind, her thoughts roaming back to the stall, to her cleaning up and noticing the broken condom, in feeling like she'd gotten thicker, like her balls were hanging lower. Just those thoughts were getting her worked up and she chewed on her lip again.

"NNnnn..H...here it...comes..." The pig panted and, with barely a second pause and never a stop to the sound of her hand flying over her slippery length, Helga felt a thick jet of hot cum splash over her ass, and then another. Two more right after that and Helga squealed, "No no the bottle! THE BOTTLE!" and after a moment, she looked over her shoulder to see her friend's eyes rolled back in her head, completely taken over by her climax. She wasn't and couldn't aim so she quickly spun around and got on her knees, holding up the bottle to the tapered tip of that exploding cock. The heavy balls were clenching every time another thick rope erupted and it happened so fast that her whole front was covered before she could get the bottle in place. Her shirt was completely drenched and it looked like she had been running in the rain, her massive tits visible through the wet white fabric.

Once she got the bottle in place the first jet was loud as it struck the plastic bottom with enough force that she almost dropped it. She found it hard to hold in place with her hands covered in the slippery seed. She could feel it running down her asscrack to pool with her own wetness and she shivered at the feeling. She wanted nothing more than to drop the bottle and take care of herself. It had been days, but she didn't want to contaminate her experiment.

Ilyana kept going, each rope of cum splattering and splashing into the bottle, filling it slowly. She got the bottle as close to the lid as she thought she could before she ran the risk of nearing the end of the gym period and she quickly stuffed the slimy, dripping, stinking bottle of pig cum into her bookbag. She didn't have time to clean it and she knew her books would reek of sex forever but what else was new at Celestine. She quickly took off the rest of her clothes and tossed them in too and ran to the shower to quickly clean off.

Back home, locked in her room, she barely could make it in the house before she had started unzipping her bag. Her mother was at work and she knew she had at least a couple hours before she got back. She was ready. She went into her bathroom and stripped out of her uniform, taking a seat in the bathtub. She had been rock hard her whole ride home, her whole walk back up to the house. She couldn't take it anymore and she unscrewed the lid to the sloshing bottle, raising it to her lips. Her nose scrunched at the smell. The strong odor was both familiar and unfamiliar to her. Everyone was different, but mostly she recognized it for what it was.

She wanted to get it done fast so she started gulping. The first gulp made her cough and she spilled some down her front, coating her tits in pig cum for the second time that day. She recovered quickly and started to chug. She was a small girl and almost 64 ounces was so much. She was on a mission though, she had to know. The thick, pungent, slimy seed raced down her throat to fill her up. Her stomach started to swell with all the liquid and she worried she was going to throw it up and waste it all. Her stomach hurt but she kept going, willing herself to relax. At first nothing happened but after a few moments she felt that feeling again, deep in her groin, at the base of her pelvis. She opened her eyes and looked down, past the bottle of cum she was drinking like a starving girl in the desert and she almost gasped, eyes growing wide. Her cock was growing. Longer, thicker. Her balls swelled too. She watched as inch after inch was added to her length. Her balls grew almost like she was pouring that pig cum directly into them, filling them like the condoms she was filling before.

In the end, she couldn't make it to the bottom of the bottle. She dropped it when she came. The feeling of her skin stretching to accommodate the two feet of new mouse-cock was a little painful and the softballs that settled between her thighs tightened again, her cock erupting and splattering against the far wall and she convulsed. Her cum and her friend's mixed together and, after several more jets from her newly grown length, her eyes rolled back like her friends and she was lost to her climax. Her last coherent thought before her mind was flooded with pleasure was that she was going to have a lot to clean up before her mother got home.
