When Ken woke up, he could still feel Tommy's arm elbow deep up his ass. Ken wanted to protest but found he couldn't. He couldn't move at all. In fact, as he woke up to realize, Ken was hanging like a cloth from Tommy's arm.
Dr. Winkler was also in the room and Tommy said, "He is definitely more stretchable now. Watch." Tommy stuck his other arm up Ken's ass until both arms were elbow deep.
Finally Ken grunted. Tommy said, "He's awake now. Hey Ken, I can reveal what this experiment is about now. We're making you stretchable and elastic just like a superhero. Unfortunately it's going to take some training before you can control your own body so for the next few months, you're just a toy for me to play with. I'm supposed to keep stretching you as much as I want until you learn how to stretch yourself."
Tommy continued, "All of you is stretchy. Watch me stretch your dick out." Tommy grabbed Ken's dick and pulled on it until it was three feet long. Then Tommy used it to tie Ken up into a bundle. "I wonder what else I can do with you."
Dr. Winkler said, "You can use him as a towel. You can wear him like underwear or as a skin-suit. Ken can be just about anything you want. Think of him like living lycra or living rubber."
