My cousin is spending a few days at my house, damn, it's pure provocation

My cousin is staying at my place for a few days, damn, it's pure provocation because she puts on a bikini in front of me and the way that pussy and ass are showing, she knows I'll end up looking, and not only that, I honestly think she's thinking about fucking me. Nothing's happened between us yet, but I don't even want to imagine what it would be like to have sex with my cousin...
