This is the story of my first time doing a full swap with another couple, which ended in an MMF DP. My girlfriend R and I were in our late twenties and had been together for about 6 years at this point. I am white, 5’9” slim build, she is mexican, fairly slim build with the perfect curvy ass. We were secure in our relationship, and had tested the waters of an open relationship in the past. Prior to this, we had experimented with playing with another couple once before. That time, though it was fun, the girl was clearly not into it, and was uncomfortable with me touching her. The most that we did really was spitroast R for a few minutes, and the majority of the session was spent with our own partners. Now, on to the full swap. Skip to *** for the sexual part.
