"Hello Sam."
Sam took a step back. She did not know this teenager. This boy. "Who are you."
"My name is of no importance," the boy took a step in. "What is important is that I made a mistake. And you are the result. You're ruining lives Sam. And I can't have you doing that anymore."
Sam was near-speechless. "How...?"
He closed the door behind him, turning to face the beautiful body Sam now possessed. He admired it. "Now what are we going to do with you?"
Sam regained her wits. "You get out of my goddamned house."
The boy shook his head. "Now now Sam, we can't have a lady speaking like that now can we."
He stopped, taking on a serious tone. "Strip."
Without control of his body, Sam began swaying to some unheard music, sexually removing all his clothes and tossing them about the room. He had never so much as danced before, yet here he was stripping like a pro. Only her panties remained before the boy said, "Stop. Don't move."
The boy began pacing in a circle around Sam, eyeing her like a piece of meat. Sam was terrified and wanted desperately to move. "I don't blame you for wanting this body, Sam. It really is magnificent. But what you did to Denise is unforgivable. I think you need to know what it's like to be in her position."
He stopped in front of Sam. "First, you'll need an unfamiliar body."
And with that, Sam felt her body change all at once. Hair sprouted from everywhere, her face pushed out into an unfamiliar shape, her ears burned. All at once her new body was strange and unfamiliar. Jon moved a mirror in front of her, and Sam gasped.
She wasn't even human anymore. She looked like a wolf and yet still a woman. Fur lined her entire body.
"Second, you won't be able to control what you say or do." He paused. "Answer me: do you find me sexy?"
"Yes." Sam's eyes widened. No, this boy was controlling him. How?
"What do you want to do to me?"
Sam's voice oozed sexuality and lust. "I want to tear off your clothes and mount your cock. I want to ride you."
"Do it."
Sam suddenly found herself able to move, but the only thing her body wanted was to fuck this boy. She revolted, but could do nothing as she literally tore the clothes from this boy's body. She unearthed the boy's cock, hard and ready. She positioned herself above it, the boy laying under her on the ground. She readied herself to ram down on that delicious dick.
"Stop." Sam regained herself in mind only. She had wanted that more than she had ever wanted anything.
"Stand up and wait for me." Sam stood, staying where she was, head tilted down.
"I will not do to you what you have done to others. You are a monster, I am not." The boy walked back towards the door, his clothes magically reappearing. "Denise has been taken care of. She has her body and her mind back. But you will be punished. This is your form now. You will learn to like it...or not."
The boy opened the door. "Your lab no longer exists, nor does your knowledge of your invention. I will be watching you. Goodbye Sam."
And with that, the door closed, and Sam regained her body. She ran to the door, ready to tear apart that incredulous boy. But when she looked out on her street, no one was there.
