A submissive twink has got himself a membership at a local gym - one that's got a reputation for man-on-man action in the locker room. He's also got himself his first chastity cage, and he's discovering how much he loves the denial of caged workouts as he gradually gets used to longer stretches at a time locked up. Ultimately though, he doesn't want to just lock himself up; he wants to find a keyholder who'll take charge and control his access to his own body. Meanwhile he's happy servicing anyone who wants to use him. It's not long before he's getting the attention of the other guys in the gym, and they're not shy about showing it. Each chapter tells the story of a different locker room encounter as he gets fitter and more confident about being a locked submissive, all the while hoping that maybe he'll meet someone who can become his long-term keyholder.
