Jen's boyfriend knocked on the door.
"Hey babe, what's up?" He gave her a kiss.
"Just a little prank call." Jen said, in the back of her mind she wondered if it could happen. They spent most of the morning watching t.v. and talking, Brad then suggested that they have sex, Jen nervously agreed, not wanting that freak to win his sick mind games. Brad went into the living room and closed the blinds as Jen paced nervously in the kitchen. When she got the nerve to walk into the living room, there was Brad, naked and sitting on the couch, his rock hard 13 inch cock throbbing, she didn't know it but he had been taking male enhancement drugs to get huge. He stood up all of a sudden and stood still.
"Jen, what's happening? I can't move." He panicked, she involuntarily stripped, crying, she didn't have the heart to tell him. He tried to stop his bodies forward movements but to no avail. She turned around and pointed her ass out as his hands grabbed her hips and his body started to hump her.
"Jen! I can't stop! Helpmmmm!" Brad tried to speak as his mouth melted shut, he couldn't see either. She screamed as his head started to shrink, his chest started to melt into her back, his body fought tugging, making the changed more painful as it yanked against the flow of the changes. Sobbing Jen felt her new half in its entirety, her cock slamming her ass constantly, she felt his head disappear as his arms proceeded to do the same. She screamed as she cam into herself, moaning and sobbing from pleasure and fear. Her changes complete she felt her male legs lift her up, she tried to fight, the new angle of her penis thrusting even harder, her male legs turned her around, spread bow legged as her body bounced from her now continuous masturbation. Screaming her body opened the door, she was forced outside, completely naked, it seemed that time had stopped just for this, her manly legs pumping as they lifted her weight, still humping her. All she could do was scream as her new legs made their way to their first destination.
