Scarlet and Violet are two friends who were at the library reviewing the material one last time before the exams. They had eaten the food they had brought from home, as they considered the food from the school cafeteria to be very caloric. They tried to concentrate on studying despite the noise that was coming from outside the library. They were trying to concentrate on studying despite the noise that was coming from outside the library, but when the noise of something banging against the door started, Scarlet lost her patience and went there to see what was happening and to scold the person responsible for the mess.
Scarlet opened the door carelessly and, as she did so, she saw something large and white flying towards her face, which she only had time to close her eyes before being hit full-on. Whatever it was was pasty and spread over her head, sticking mostly to her hair. She couldn't help but swallow a little and as she wiped her eyes she heard the door slam shut, which she soon saw Violet had done.
"I don't want to believe this is happening, it's full of mutants out there." Violet said
"Mutants here at school? But where did they come from? Don't tell me an outbreak like the one on the news a few weeks ago is happening here at our school. If that's true then... oh no, I swallowed the cum. I'm certainly infected now." Scarlet said
"No, I don't want you to become a mutant. We have to get help fast." Violet said and looked at the librarian hoping for some help, but the librarian was totally freaked out and ran out to lock herself inside the file cabinet.
"It's no use Violet, there's nothing you can do for me. I can feel I've already started to change, see." Scarlet said and pointed down to where the tent formed in her skirt could be seen. She clearly had a cock between her legs now, which stretched her panties to the fullest and lifted her skirt, and her new cock was still growing.
"No, stop, this can't be happening." Violet said as Scarlet instinctively undressed and allowed her to see her breasts merge and morph into an ass, then her original buttocks swelled and transformed into a pair of breasts the size of potato sacks.
Seeing her friend try to get closer, Scarlet tried to tell her to keep her distance, but she couldn't as now her mouth and nose were changing and becoming a single vertical slit, which she soon recognized as a vagina. She then ran from her friend, resisting an urge she felt to infect her as well and doing her best to keep her distance. It was difficult to run with the weight of the breasts behind her, which was complicated by the huge ballsack that grew in the place of her old vagina, just below the cock that had stopped growing when it reached three feet in length. Seeing no choice, she knocked over a shelf of books, startling Violet and taking advantage of her distraction to hide. She thought she was lucky, as her vision was fading as she felt her eyes shift, finding a place she believed was safe before she went totally blind.
"Please Scarlet, don't run away from me. We have to get help, there must be some way to get you back to normal." Violet yelled at her friend, who was now touching the place of her eyes and finding lips and a set of teeth in each.
Realizing that her eyes had become a pair of mouths, Violet tried and managed to speak through them by saying "You know very well that there is no cure for it. Now get out of here, I don't want to infect you."
"I can't leave you alone at a time like this, and even if I wanted to be full of mutants around the school, I wouldn't be able to escape." Violet said to Scarlet, that had regained her sight, seeing that she had been found.
Scarlet clearly noticed that her odd-angled view indicated that her eyes were on an odd part of her body. She soon discovered that her eyes were now on her basketball sized balls, doing this she could feel and see all of her fingers thicken, lengthen and the skin retract at the tip as they became dicks, thus completing her transformation.
"All right, stay in the library but keep your distance from me. I'm fighting with all my might against the instinctive urge to infect you, I don't want to risk a relapse." Scarlet said
Violet sat on the floor where she was. She understood her friend's desire not to make her a mutant either, but she couldn't quite leave her alone either.
