As Jen and Claire thought about what they should do with their free time they wandered the halls aimlessly, thinking that something to do might jump out at them eventually. A short while after the bell for fourth period rang the sisters began to hear a strange noise coming around a corner. When they went to investigate they found the sound, which they could now clearly identify as several voices in the throes of passion, was coming from behind bathroom a door. This door, much like many of the other doors around the school, was designed in a way that it could be opened and used by both human students and mutants of both extremes of the size spectrum. The sign indicated this as a unisex bathroom, something that the sisters were sure the school didn't have originally. They figured that due to the wild and distinct shapes many mutants have the reality alterations made by the pills must have combined a pair of bathrooms into a single one to give larger mutants more space, and give mutants with strange body shapes and functions the accommodations they might need.
Figuring that the handle would be awkward with their clumsy dragon claws, Jen and Claire opted to press the door open button, the kind that many places had for people in wheelchairs. As it turns out it also helps people without opposable thumbs as well and the sisters found the door swinging open before them, causing the volume of the voices to significantly increase. The inside of the bathroom was essentially what the sisters expected it to be: a row of stalls of various sizes dominated half of the right wall with the rest filled in with similarly varied urinals. There were also sinks set up at multiple different elevations along the left. One thing they didn't expect was an open entrance to another room in the back, which just so happened to be where the voices were coming from. Still curious, the sisters walked across the bathroom and over to the entrance. When they looked into the room beyond they saw something that surprised even them.
The room beyond was filled with various tools and machine with one clear purpose: sexual relief. Glass cabinets with various sex toys, wide benches with plastic wrapped cushions, and pumps of both the breast and penis variety lined the walls. As Jen and Claire took in the spectral before them, their eyes were soon drawn to the source of the noise that had led them here to begin with. In the back corner was Josie, the girl who had pulled Claire out of the previous chemistry class orgy. In fact Claire quickly realized that this was the same bathroom she had been taken to back then, once again reshaped for the continually growing population of mutants attending the school.
Josie, having been in the classroom when their smoke cloud went off, had once again transformed. Her body still retained its overall shape and size (a twenty foot to the shoulder taur with a normal sized upper torso) but the details had been altered significantly. Her upper body now sported a third breast per row, giving her nine in total. The centre breast as well as the four outer corners now sported twin vaginas in place of their nipples while the remaining four still sported regular nipples. Her lower body, previously that of a griffon, had also been altered. The front half of her tauric body was now distinctly bat-like in appearance: her front legs and wings now joined into a pair of wing-arms covered in thin, dark brown fur. Her back half meanwhile was the rounded hindquarters of a spotted hyena, which now sported a sizable canine penis. Said cock was presently being used to fuck a massive fleshlight-esque device propped up on four sturdy legs, allowing it to be easily mounted by tauric mutants.
Alongside Josie was another pair of familiar faces: Baph and Maggie. The pair were still a conjoined angel and devil but instead of sharing one body evenly split down the middle they separated at the hips, giving them separate upper bodies with two breast each, one wholly angelic and the other wholly demonic. They were also much smaller, having shrunk down to a measly foot tall, with only two parts of their body not having shrunk in relation to their height: their wings, which were now positioned at their hips, and their cocks, which had only shrunk down to half their previous size. The conjoined pair were busy fucking Josie's centre pair of nipple-pussies as they used their mismatched wings to hover at the proper height.
Jen and Claire assumed that the trio had come here to blow off some steam after Miss Taylor prevented the class from descending into an orgy again. The sisters had also been denied a chance to relieve themselves and considered joining in on the fun, or even simply making use of the facilities themselves as they spotted a similar device to the one Josie was using that looked like it was the appropriate size for them nearby.
