"Chuck," Doug called. "Time to get turned into a monster!"
Chuck went to Doug.
Doug set up Chuck's tf into the site, and ordered Chuck to undress. Chuck obliged. He removed his lab coat, and pulled off his shirt. He kicked off his shoes, peeled off his socks, loosened his belt, and pulled down his jeans and underwear as well.
He put his clothes in a neat pile on the armchair in the corner of the lab, and stood, stark naked, in front of the camera, his dick dangling down.
After all, this was for science, and modesty was sort of silly when you were trying to record physical changes.
Greg helped Chuck into the lab table and activated the restraints on his chest, arms and legs.
"Begin the transformation!" Doug told Greg, who activated Chuck's monster transformation.
Immediately, the transformation began.
Chuck immediately felt a burbling in his gut, and with a pop, his bellybutton grew a yellow monster eye. His eyes became slug-like. His Dick shrunk right into his body. His hair fell out, and his legs shrunk. His feet elongated, and grew claws on the toes. Finally, his skin darkens, and big blue spots appeared on his body.
Chuck was a monster.
