I was in LTR sort-of MMF scenario once for over a year. It was my roommate and his girlfriend. Unfortunately, I didn't realize I had bi tendencies but I also wasn't at all attracted to my roommate but periodically we'd all get naked and the extent of it was that she sucked my cock while he fucked her. We did this a bunch of times, and then I ended up fucking her on the side without his knowledge.
Years later, I had another MMF with my girlfriend and HER roommate. She sucked both of our cocks together and we did a little cock jerking ot each other, and this guy was actually hot and had an nice cock. I was fucking her when she was sucking his cock and I started kissing her, and the dick was only a millimeter away but for some reason I was too scared to grab that thing and suck it myself, but I did feel the taste of his cock on her mouth and tongue. Unfortunately we broke up later, not for this reason at all, she was just a bitch but I regret not sucking that cock with her.
Fast forward a couple of years and I had my first MMFF foursome where I finally sucked cock. Unfortunately, again I wasn't that crazy about the guy and hence my nervousness was justified b/c it didn't do much for me, although I am more than happy and willing to try it again! MMF or MMFF. I'd really like to suck a cock together with a chick. I can't think of anything hotter than that. I don't really care for anal that much, but blowing a dude with a girlfriend sounds like the most awesome thing ever but I have yet to make it happen. The good news is that my FGF is up for it and finds it exciting but where do you find people apart from strangers in a pub, or the utterly terrifiying craigslist? I have been
jerking off to this site as a substitute lately but I gotta make this happen. Any volunteers in So Cal?
