My boyfriend and I have lived together for a couple of years, but we have since broken up, and live together as roommates. We live in tight quarters with not a lot of privacy. I hear him masturbating a lot and lately watch him without him knowing it. It really turns me on and am finding that the only thing I think about while I masturbate is thinking about him masturbating. The weird thing is, I have never had any desire to have him masturbate for me (in fact, I would be embarressed or something), but having him do it without him knowing is such a turn on. When I see him humping his pillow gets me extra excited for some reason.
I don't know what is going on. The thing that worries me is that is the only thing that I get aroused by. I can't wait to get home just to catch him in the act. On Sunday's I stay home just so I can watch him...
