Kyle's warm jizz spreads through his body, and runs down into his legs. Chad's arms start to shrink into his body, they come loose of his leather cuffs. He tries to pull himself free and get away. But his legs don't seem to move, he tries to pull with his hands, but now his ass seems glued to Kyle's crotch.
"Aww fuck yeah!" Kyle moans. "This feels great. I'm going to enjoy having you as a tool, Chad." this makes Chad scream again. This time he manages to spit his boxers, but no screams come out. In fact he can't really breath any more, like he has no lungs. He feels his insides melt and twist around, and his legs involuntarily curl up against his body. He can hardly feel them any more. They feel all bulbous and round. Chad feels Kyle's warm man juice flow through his body. Then he suddenly feels it in the back of his throat.
Disgusted, he tries to swallow it back. This works until his throat changes and doesn't seem to have muscles any more. Chad screams mutely as cum starts oozing from his mouth down to his chin, and dripping onto the bed. His arms are now shrunk into his body almost completely, now just the size of fingers.
"Ahhh, you're small enough to manage now Chad, would you likes to see yourself?" Of course Chad doesn't answer, but just coughs up another glob of cum. He can taste the bitter substance, and he's sickened by it. He then feels Kyle grab his shoulders, being touched feels extremely erotic. He''s then lifted and pointed at a mirror. Chad's eyes go wide with absolute horror at what he sees. He's now just an upper body, about two feet long, attached to a rather large pair of balls that used to be his legs. He is literally becoming Kyle's cock. He can't scream any more, all he can do is sputter jizz all over himself from his open mouth. He feels all his teeth fall out. Chad's body shrinks down, soon his legs are the size of a large ballsack, and his body is about twelve inches long. But he keeps shrinking. His chest reshapes to become round and the same size all along his body.
Finally his entire body is just like a large cock, his face starts changing. Chad is forced to watch in horror as his nose becomes flat and vanishes from his face, his jaw line and head flares out, his face becoming round like a cock head. His mouth forms into a piss-slit and keeps leaking cum. His ears vanish into the side of his head. Then Chad's eyes roll back into his head, shrinking away. The last thing he sees is himself in the mirror, but he looks completely like a large eight inch dick, with tiny eyes that shrink away.
Next thing he feels is an incredible sensation as man juice rises from his balls and shoots from his mouth. He can taste the cum in his mouth, and it's disgusting. But he can't help but enjoy the orgasm. It goes through his whole body, since his whole body his just a cock.
Somehow he can still think, and even see things through Kyle's eyes. He can talk, but his words are only thoughts. He sees Kyle looking at himself in the mirror, a nice thick eight inch cock dangling between his legs.
"No more teeny-weenie for me. This big one is much better. I think I'll name it Chad." Kyle says as Chad screams inside Kyle's head, but on a command he can't think words any more. "You stay quiet Chad, until you're ready to be a good cock." Kyle thinks to himself, somehow Chad can hear his thoughts. Chad is filled with despair, he's not another teen's cock, he has no humanity left. Will he be like this forever?
