Jen avoided meeting Maria's gaze. Her eyes bore straight through Jen's soul. The hatred was palpable, and tears were welling up in Maria's eyes.
"Do you fucking mean it?!" she growled, trying not to cry in rage. Everyone was looking at them, silent.
"Y-yes, of course!" Jen said, trying to weasel out of this situation. She wasn't used to being on the receiving end of an attack, especially not from a mutant dick-girl hybrid pile of boobs she's relentlessly bullied.
"I don't believe you!" Maria roared, kicking Jen from her chair. She immediately jumped from her seat and pinned Jen to the ground, knocking the wind out of her. As Jen gasped for air, Maria leaned down over her. She desperately looked around for help, but everyone just watched. Some even laughed. They all knew how big of a bully she was, and were tired of her holier-than-thou shallow, rich kid schtick. They gasped as Maria slammed her face into Jen's using her prehensile cock-neck. Then Maria began to moan.
Jen struggled, groaning and trying to push the mutant off of her chest, but there was no hope. Her legs were far too strong, and the extra weight of her new breasts didn't help. Jen's grunts and groans were silenced, however, as Maria let out a longer, lustful moan. Something was pushing up her neck.
"Nmmmph!!!!" Jen tried to scream, knowing what was coming next. Cum shot into Jen's mouth like a firehose. Jen's cheeks visibly bulged as gallon after gallon of mutant saliva cum was pumped into her mouth and down her throat. She gagged, but couldn't stop the tsunami. Her stomach bulged. In the moment, it felt like it would never end. Nothing felt real, she couldn't believe this was happening to her!
"ENOUGH!"
A loud plop jerked her back into reality. A security guard wrangled Maria off of Jen, cum spilling from her mouth. Jen coughed, some of Maria's cum spilling out of her full mouth. She gagged as she took in the situation. Her desk was knocked over, and the guard had pulled Maria to the side as the two of them calmed down. Jen felt... numb. She expected to be angry, but she was just shocked.
Maria, however, was still spitting cum at the guard, frothing incoherently. She was irate, and tried to lunge at Jen again, but soon began to calm as her dick-neck became flaccid again. Their teacher suspended both of them. As Jen looked around, everyone in the vicinity was splattered with a little bit of Maria's cum saliva, but especially the guard. She noticed something push out of the back of his pants, and fear began to overcome her. Transforming other people with her pills was all fun and games because it was happening to other people, people she didn't really care about. But if Maria's cum had transformative qualities, she was about to be in for a rude awakening.
