How do you know he wouldn't love to see another man inside you? I for one would love if my wife would have sex with another man as long as she would either tell me about it or have it with me there.
My wife knows that I want to eat her as another man is fucking her and do clean up after they finish. I really am not sure it will ever happen but I keep hoping and trying to get her interested. She cums hard as I am eating her and I suggest it so there is hope.
