Her first period class was a lecture class, where the teacher typically just speaks the lesson while the students take notes. This teacher was particularly annoying however. He hated being interrupted by just about anything. Any noise besides his own voice and pencils on paper was considered "too loud" for him. He bairly tolerated sneezing and would often send students out of the room for excess coughing.
The only 2 redeeming points of the class were that it was extremely easy, and that the teacher NEVER turned around until the bell rang unless he is interrupted by a concerning situation (he often would just shout whatever his complaint / order without even facing the class). So for most students taking this class, this was basically nap time or a place to do their homework.
But this is exactly the issue right now for Jen. She has no means of giving her pill away without causing a huge fuss. Jen typically sat near the back, but as she often slept, she didn't bother sitting near anyone. So she reluctantly put the pill back into her own mouth at the 10 minute mark.
She immediately felt the pill start its work, and felt it focus mostly around her core and chest. The first change was with her boobs. They turned crystal clear and now felt like glass. Yet they could still move about, were shaped the same, and could still be squished, just like normal boobs. However a clear glass-y sound now rang out whenever they bumped into each other. The other thing about them, is that they clearly are hollow now, as Jen could literally squish them flat. The good news is that when the pressure was let off, they returned to their normal shape and size. Which now that she looked closer, seemed to be slightly more rounder than usual, and just a bit bigger too.
Jen then felt her stomach churn and her gut begin to cramp as her intestines and organs moved around and simplified significantly in order to make room for what's still yet to come. Specifically, her pussy lengthening up her torso and her womb connecting up to her glass-like boobs, forming a single large, empty chamber in her chest that could be looked into through her boobs.
Her pussy was next, as it spread out into a square shaped opening and solidified with the opening now pointing directly forwards. Her clit pushed about 2 inches out from her pussy and widened as well. It gained a gear-like shape near the tip and became ridged, with only the tip now being able to rotate fully around itself.
A pinch in her belly button made Jen nearly make a sound, as it widened and gained a slotted groove along the back wall's lower edge, just big enough for a quarter to fit into perfectly. Jen looked down in horror as she felt her gut rework itself to now also be an empty chamber. One that is connected to her belly button and could be accessed from her asshole, as she felt a direct connection form to it.
Jen was then forced to her feet and made to stand up perfectly straight as a metal pole began pushing down out from her ass. It pushed all the way down to the floor and then some, forcing her to stand on the balls of her feet when if finally stopped. The metal pole then spread out into a thin base, securing itself a stable platform while also ensuring that Jen could still bairly move around. But only if she stood fully up on the tips of her toes. Aside from that, Jen felt as if she was literally sitting on a dildo which had been shoved deep into her ass.
If this were a better situation, Jen actually would find the pole to feel extremely good, as it did feel very pleasurable for her. But given the situation she is being faced with, the pleasurable feeling from her ass being impaled on a metallic rod is more of an annoyance at the moment. It was then that her toes blended together into a single mass. The from her toes to her mid thighs, a black, shiny material appeard. She looked as if she was wearing thigh high socks made with a shiny black latex.
A pair of similar looking, thin rods grew up out from the metal base by about 5 inches. Jen then felt really strange, and suddenly she could feel the metal pole and the two new rods as if they were part of her body. Her feet them moved back towards the rods, and rested her elevated heels on top of them, giving her the appearance of wearing heels, but still allowing her to move her foot at will.
Jen found that with just a small bit of effort, she could pull her feet off of the rods, similar to pulling apart two magnets. However she quickly learned that doing this should not be done so often, as anywhere else her foot went, it bairly could touch the ground, if at all. Only about a 12" radius area around her pole was the only area where Jen's toes could still make some amount of contact with the ground. Anywhere else was simply out of her reach. And by removing her leg support, her body sank a bit further onto the pole too. And while it wasn't at all painful for that to happen, it did amplify the pleasure by almost double per inch dropped.
Jen stopped trying to stand on one leg and attempted to walk, which she found she could do, but only over short distances, and only on flat ground. This is because it now felt exhausting to move around as she could only make small steps and had to do it all on literal tip toe.
Finally, and worst of all, a flood of familiar looking white pills began to fill up her chest cavity, including both of her breasts. And due to them now having a few glass-like properties, specifically how they sound when other things bump into them, made quite the noise.
Jen wanted to die from embarrassment as she watched most of her classmates turn to face her. This only was made worse when her clothing vanished, save for the latex-like material cladding her legs and feet. She was completely on full display, and everyone was staring at her.
A mix of excitement and humiliation began to build up rapidly inside her, until she couldn't handle it anymore and felt herself cum, only not with her pussy. Instead, her ass began to leak a bit of clear fluid which traveled down the pole and into a small pool forming on top of the base. At the same time, a copious amount of drool suddenly flooded her mouth, and forced its way out with enough pressure to let it fly a little bit and land on top of the desk in front of her.
A few students, most of which were boys, giggled at this, but most of them just turned back to continue with whatever they were doing without even batting an eye. The teacher didn't even turn around and simple shouted out "Jennifer. I will excuse it today as a first offense, but do not ever refill yourself during my class again. And Amber, I better not find a single drop of her lubricant left behind. Be sure to wipe it all up. Do I make myself clear girls?"
"Y-yes?" muttered Jen who is still very over whelmed by the situation.
"Sure thing, Mr. Leaflann. I can do that." said Amber cheerfully. She then made herself over next to Jennifer and set her things down on the adjacent desk while moving the chair over to the side of the room. She also quietly wiped down Jen's drool covered body and her recently made mess with a wet cloth she had gotten from somewhere. She was even extra careful to not let Jen's breasts bump into each other while she cleaned them.
Jen didn't want to admit it, but Amber was making her very horny while cleaning her breasts, and she would likely orgasm yet again if she continued to rub them clean. She even had to cover her mouth with her hand to keep herself from moaning when Amber began cleaning her square shaped pussy chute and gear shaped clitoris tip. However the long trails of clear fluid flowing down her pole were clear enough signs of Jen's second orgasm of the class as her lips began to push open, letting another flow of drool out as she quietly climaxes. This time however, she doesn't squirt it out and it simply flows down her front, undoing all of Amber's work. Amber then dropped the rag from her mouth and mouthed "Woops, sorry about that" to Jen and decided to just forgo the cleaning until then end of class.
Jen came down from her climax soon after and once again felt extremely embarrassed by her current state, and yet she didn't try and cover herself up either, as part of the transformation had stopped her from preventing others from both using her, and seeing her current stock through her clear boobs. Jen was forced to accept the fact that she now was partially a pill dispensing candy machine, full of the exact same pills that she will cough up each hour. And that the world now treated her as such too.
The lecture ended soon afterwards, and Amber carefully cleaned up Jen once again with her mouth and a rag. She also let Jen lift herself onto her back and carried her out of the classroom. Apparently the two of them now had matching schedules. And after a few quick questions, Jen found out that according to Amber, she always helps Jen out. This was decided due to them having identical schedules and because Amber can easily move Jen around the school on her back. While Jen can help Amber with things that require hands. They apparently are much closer than what Jen can remember at least, as her mind did not adjusted to fit her new form like everyone else seemed to have. But now everyday she gets to ride on the back of an armless centauress, who is also genuinely nice to her, so that's a plus.
Amber had to use the bathroom, so Jen slid herself off of her back and squirmed in pleasure as her stand impaled into her ass a good 4 inches before she remembered to stand up on the balls of her feet and rest her heels on their respective posts. After setting herself up, Jen waited for Amber to return from wherever it was that an armless centauress goes to relieve themselves.
And before even a minute had passed, some girl came up to her and stuck a quarter into her belly button. She then grabbed her gear-shaped clit tip and began cranking it to the right, causing Jen to loudly start moaning uncontrollably, though no one seemed to care about that. After a full turn of her clit, a single pill dropped down from inside her pussy and was caught by the small lip formed by the outer rim of her square pussy chute's opening. The girl reached a finger in and scooped the pill out. She then thanked Jen and swallowed the pill right there so that Jen could still watch her transformation.
