Just came up with a second idea!
After he closes the garage behind her he takes her into the apartment and throws her onto the couch. He leaves to clean himself up, when he comes back in he tells her that he plans on keeping her with him so she doesn't go to the cops. At first she's terrified but there is a part of her that finds him extremely sexy and something about the way he's acting turns her on a bit.
As time goes they both realize theyre falling for eachother and so everytime they go out somewhere and a guy looks at her in anyway he takes her home and fucks her to remind her who she belongs to...secretly she likes it.
Things I want to include in this: Rape, Light Bondage (Tying up, blindfolds), Knife play, biting!
