I vaguely remember it starting with a girl doing self bondage with a pair of handcuffs that unlock after a set amount of time. She gets it all on but when it doesn't unlock by itself she's forced to wait for her guy roomate to free her. Instead he has sex with her, and talks with her. Then after a couple days when she has to go to the bathroom he takes out the sex toys and places her on the toilet to do her buissness. Anyway, her handcuffs automatically unlock after multiple days instead of hours. She frees herself but finds the room locked from the outside and the windows barred. And when she hears him entering the apartment, she panicks and puts everything on but sets the handcuff timer to free her again. And then the guy enters and looks around and messes with her handcuff timer. Also I think they were both in college and she moved there without telling any of her family or something like that. Does anyone recognize this?
