This was in the early 70s truthfully, it was my wife’s idea because she was in bed with her mom. She had a brother, a really good looking guy a little older than myself and he got fucked by his dad and he fucked me as well
So I gather that your wife knew that her father was fucking you in the ass at these pool parties. I'm kinda surprised she was ok with it. I guess she must have been fucked by him as well. Did he also have sons? Were they also fucked by their dad?
