But my foursome was a bit different than most foursomes in P4P. Mine was with my GF, a lesbian friend (not bi, but 100% lesbian) who had always wanted to bang my GF, and a pro who we invited to keep me "occupied" while my lesbian friend was doing my GF. lol
Speaking of Thai Girls, I dated a Thai provider for quite some time in Dallas, the agency she worked for usually had a rotation of anywhere between 5-7 providers at any one time. There was a guy who used to be a TER member (nice guy too) who did a BUNCH of threesomes, several foursomes, and If my memory serves me right a couple of fivesomes and even one "sixsome" (if that's even a word. lol) and wrote reviews of all of them
Personally, I have to agree with you, I think the idea of a foursome (or more) is more exciting than the session itself. If they are wearing FC's can you even imagine how many condoms you'd go through?
Come to think of it, I do believe that while I have never had the "rainbow foursome" we were talking about, I can think of a few times where I have fucked a White/Black/Asian/Latina girl all within about 36 hours of each other. I am trying to think if I have ever done it all in one day, but I think the shortest period of time to do all four "flavors" was once when I did an overnight with a Tica in Costa Rica, had sex with her at about 7 AM, after she left I did a black girl later that morning before getting on a plane and flying home, where I did my Korean GF later that night back in Atlanta and then had a session with a white girl the next day at about noon. So I guess that was all four flavors in about 30 hours or so. lol Ah, those were the days.
