Today my wife’s brother visited and I was behind him while he was standing at the door to the living room, admiring his amazing bubble butt. He works out.

All of a sudden I was imagining him having sex with my wife/his sister. I’ve always liked incest stuff but actually going ahead and visualizing my wife’s hot brother banging her was a new one on me, and I find the whole thing arousing.

My wife brought me into the conversation and I had no idea what they had been saying and then my brother in law turned round and I couldn’t speak, embarassed.

My wife pointed out that I was tired from work, which is pretty much always true, but just made me think about taking them both to bed with me. Shaking, I went upstairs and lay down there, my head spinning.
