His Keyholder's Rules: A MM BDSM Chastity Straight to Gay Erotica Story

If you want to use what you’ve got locked up, you’re going to have to ask me for permission.

Chris’ roommate Aaron is too good-looking, too muscular, and too distracting. Fortunately, Chris has this great new device that will allow him to lock away his arousal until he can fix his life and think straight again.
Demanding that Aaron hold his key might be a mistake. Because once he takes control, Chris' ultra-hot roommate has some demands of his own, including a hard prostate milking in chastity and a nice long punishment edge to teach Chris not to touch what isn’t his.
Chris isn’t supposed to like it, he's not gay. And isn’t chastity supposed to make him less turned on?
But the more control he gives to Aaron, the harder it is to deny that he wants more.
Is Chris ready to surrender everything to his dominant keyholder?

This is a 16,500 word erotic story about two adult male college students who engage in bondage, chastity, edging, humiliation, submission training, and lots and lots of denial.
