Eric roughly cleans the now flaccid cock with his used towel, forgetting for a moment that it wasn't just a toy. His roommate protested the treatment, his tip still far too sensitive after the orgasm.
"Change me back right now or I'll..."
"Or you'll what? I don't think you're in a position to argue at the moment." Eric laughed cupping the rapidly shrinking cock that used to be his roommate in the palm of his hand. The shaft continued to pull back towards his balls, loose foreskin rolling up until it slid partially over the cock head.
"Maybe a day or two in chastity will change that tone of yours." Eric pulled a small metal cage out of his desk and set Aiden the cock down next to it. The size of the cage looked like it might be a bit on the small side, but it would have to do for now.
He slid Aiden's balls through a small metal ring, the tip of his cock pressed right up against the metal bars at the top of the device. Aiden's entire flaccid body compressed inside the cage, and he whimpered when he heard the click of the lock sliding into place.
"There, that's better, isn't it?" Eric grinned down at the helpless toy and gave the balls a light tap. Aiden felt the jolt go through him and he pulsed, his body trying to react and harden, but unable to do so inside the constraint.
"Please, I'll do anything you want." Aiden begged.
Now there was a thought.
