So....after much talk about it we agreed that we would have limits. We decided to try it, but agree that it would only be once unless we are totally ok with it. Last weekend we had all been drinking, and I told her just to go over to him and try something. She sat on his lap and started kissing his neck. Before long he was playing with her tits. When she took him out he was already almost hard. I must say it was a thrill to see him go in and out of her. His head is huge and kept popping in and out. She got off big time. I am tempted to try it again.
