Fiction-The Scenario-
We're a Stag/Vixen couple. Wife Latina, I'm white. We started out as Swingers years into our marriage. So being with another man while I was also in the room (with the other wife) was something familiar to her. Over time, just watching her with another man became the turn-on. This started the Stag Vixen stage as it was just easier to find another male in a MFM threesome than it was to find another age appropriate couple.
I brought up a MMFM. She asked with who. I suggested 2 of my best friends. Both she knew as they were long time family friends. She agreed as long as they didn't go talking about it all over town.
That Saturday I took my wife to the hotel, we got settled in and later that day I met my buddies in the lobby while Lita was getting ready.
Of course I let the three of them go at it. It was insanely exciting to see her with my friend's dick in her mouth while her oh-so-familiar pussy had my other friend's cock in her. I mean, my wife just gave up her mouth and pussy to my best friends. How sexy is that.
