I only do couple swaps. And we always let the women determine the flow of the action. They become co directors and me and the other guy just follow their commands. I wouldn't say that was humiliation, but sometimes the women will have me and the other guy stand next to each other and comment on our cocks. In a way making fun of them. I don't mind it at all. It's fun. At certain points in the action one of the woman will stop and take a few minutes to direct her BF on how to fuck the other woman. And she will ask the other woman things like, "are you enjoying (ted) shoving his cock in and out of you". All just lots of fun dirty talk that really keeps the guys nice and hard. The finale is always the women coordinating me and the other guy finishing them off at the same time or close to it. Many times I will be next to the other guy as we both plow the girls doggy. We signal each other when we both know we are really close and then proceed to shoot our loads at almost exactly the same time. Exhausted we both step back and move positions to behind our GF and watch the other guy's cum oozing out.
