Years before I met my wife, she slept with her girlfriend and the girlfriend's husband. My wife says they were all quite attracted to each other. By and by, the women have talked to each other about their husbands, and my wife says the girlfriend now needs a good fuck from ME. Playing behind the husband's back is out of the question, so my wife wants to invite them both over for a romp. (This time, the men wouldn't be attracted to each other.) But now the husband is the hesitant one, possibly because his hydraulics don't work as well as they used to. I NEVER thought I'd have to "seduce" a man, but what can we tell them/him to make this more comfortable for all?
