My wife and I were in the lifestyle for over 25 years, and the only time I saw her fuck more than just me and another guy was at one of the few swing parties we attended. I was on the couch getting a blowjob, while I watched my wife on the floor with three guys taking turns fucking her. One would fuck her while she sucked the cocks of the other two, then they'd switch and another guy would fuck her. goddam that was hot.
