In the middle of class, Anna was terrified. Was it really going to happen to her? How? She was so bewildered when it happened to Jeff it hadn't even crossed her mind that it could happen to anyone else. But here she was, thinking more and more about Danny's body. She stared daggers at Danny the whole class. This was the first time she really considered him. "Him"--a boy, a teenage boy. His bloated face with a hint of facial hair, his fat disgusting belly straining his shirt. His "moobs"--not her real beautiful heavy female breasts, just a couple lumps of disgusting fat. His huge embarrassing ass filling out his trousers. His hairy legs, his thick lips, his stupid expression. His goddamn... His goddamn PENIS. That disgusting organ in his pants. She'd never thought about it for a second, but can you imagine? Imagine being in that body for even a second and not throwing up?
She started to panic and sweat. "Are you alright, Anna?" asked the teacher.
"I don't..." Anna started to stand up, not sure if she wanted to go back to the bathroom or run away or scream, but as soon as she stood up, it started.
Her shoulders, ribcage, and hips widened. Her butt turned flabby and masculine. "No!! No!! Stop it!" she shrieked, powerless to stop the transformation. Her skull expanded and her jaw widened. She stood in front of the class and ripped her shirt off, her trousers, just as Jeff had. The embarrassment she felt for Jeff was now her own. Her belly got bigger, and bigger, and jigglier, as her breasts deflated into man-breasts and her thighs thickened into a fat boy's thighs.
"No..." she muttered to her classmates, silently begging the universe to spare her, standing in just her loosening bra and tightening panties. "Don't look at me..." But she didn't know where to go and it was far from over. Her genitals started transforming, and she felt the painful wriggle of her ovaries popping out into her new ballsack and her clit growing into a thick little soft dick. She had to take the panties off, as the squished boy parts were too much to bear, and let everyone see her new genitals. She had a curly patch of pubes over her new dick, slightly squished by her teenage boy's belly. There was nowhere else to go now. She lightly caressed her new dick, silently, sweating and shaking from the humiliation.
"I guess this is it," she said, with Danny's masculine, slightly annoying voice. "Jeff's thing is contagious."
She looked up at her classmates. No one knew what to say. They started examining their own bodies, then looked at Anna, then to the real Danny. Then they screamed.
