When I was with my ex wife we had a couple who were good friends and swingers. The wife of my buddy would always brag about how big he was when she’d get ....... He had expressed interest to me about fucking my wife at the time. So the discussion of his cock would come up frequently. Needless to say it didn’t take long for one thing to lead to another. The wife swap wasn’t so much a “swap” as it was his wife and my wife worshipping him lol
My wife later admitted from the moment his wife had bragged about the size of it she couldn’t help but think about it when she would talk to him and that it excited her
