"So you're serious about this? You really want me to fuck another man?" my wife asked.
"Well, it doesn't seem fair to keep cock teasing them without offering to finish what you started," I said jokingly, but then saw the look on her face and got serious. "Yes, I think I'd like it if you did."
"But what if I fuck a guy and you decide later you can't deal with it?
Something like that could ruin our marriage."
"If you were willing to do it, we'd agree that we'd try it, but if either one of us didn't like it, we'd never do it again," I suggested.
She considered that for a few moments. "I don't know if I could do it, babe It's fun to fantasize about it, but I'm afraid that the reality would be very different."
