I fantasize about seeing my girlfriend with another man. I want to blindfold her, tie her r to a bed, fuck her for a bit, then have someone take my place. I don't want her to know I'm doing it, and I don't want her to know who she fucked. The girl has cheated on me quite a bit, which hurt, so I know that ultimately, this fantasy is about showing her that she is my property. I will do with her as I please, and give her to whom ever I feel she deserves to be given to.
