If you have been in a MFM threesome, the first time (if there was more than one), whose idea was it?
I say it just happened, but, we had talked about it for a year, in our fantasy roleplay. He was the first one to bring it up, during sex one night, and became part of the hot talk. When the opportunity finally did present itself, we hadn't planned it, and did not expect it to happen, it just did after we challenged one another. It was different though, because it was actually with two other guys instead of one, that first time. I wrote about it in one of my stories published here titled "My First MFM (Oops, Add Another M".". So technically, he brought the idea up first, we roleplayed it for a year, and then it just happened. Maybe my answer should be His Idea, since he was the first one to suggest it, even though it took a year.
A late answer, but it was my idea. At a beach party - nice breeze, moonlight, warm air, beer and tequila -- my bf and I started making out. Another very good friend (male) came by and said hello, and went to excuse himself. I told him "don't go" and reached out to touch his thigh. The "language of touch" took over, and before I knew it, I was making out with both of them. Cocks and boobs came out, then they disappeared into various hot, moist places. It was an absolutely incredible experience, as they usually are. Neither of these guys was "bi" - so they focused all their energy on and into me - its one of the nicest and most pleasurable ways to stay busy for an hour or so....
