I used to know a guy whose fantasy was to see his wife fucked by a handsome muscled man.
He took her to a swingers club, where they met a guy.
The guy fucked the lady like her husband never did, or so I assume.
Indeed, now the muscled and handsome guy is his wife's lover, he has to mantain him and let them fuck anytime they please, otherwise they'll tell around, and he is not in the position to allow it.
