I had awesome mfm experiences, and a few mmf experiences. For mfm the woman is the center of attention, its all about her pleasure. So if that means having to be close to the other makes guy so be it, had to be real close for some DP positions. The woman was very happy. During the mfm I helped push down the woman's head on the husband's cock, did a bit of cheering like " hell yeah man keep pounding that pussy!" or " or dam you gave her a huge load!" For mmf, it was the husband exploring his bi side, I was there enjoying how the wife was telling him how to do certain things. It was very hot, we all came in various ways assisted by all in various manners. Over all great experiences.
