had two 3-somes with FMF before
once was with my wife and her friend a lot of years ago. we were all drunk and high and my wife and her showered and asked me to be ready. they got each other all soapy and worked up and I got naked with a throbbing hard on and waited for them. once they got out of the shower they came right into the bed with me and it was awesome. my wife directed me to fuck her friend so I obliged. While fucking her my wife asked me to pull out, I did and my wife sucked my dick, jerked it some, and then put it back in the girlfriend for me. The girlfriend was drunk as shit and asked me to cum on her tits so as I fucked my wife was massaging my balls from behind and after a few minutes, load #1 was about the fly. I pulled out of her pussy, my wife AND her simultaneously grabbed my, about ready to explode cock, and whacked it off over the girlfriend. It shot on her cheek (I was strattled at this point over her belly), lips, neck and tits. I have to admit, it was a full gusher and covered her quite well. At that point they both waited a few minutes to let me enjoy the moments, and then both started blowing me sharing my cock and balls together to get me ready for round 2. That didn't take long naturally, now I was enjoying the attention, sucking and stroking of both of them when the girlfriend says "it's your wifes turn". Ok, so I laid my wife on her belly and fucked her from behind (pussy, not the ass) while the girlfriend got behind me and stuck her tongue in my ass. WELL, if that didn't make me almost lose load 2 right there, but I held off and kept enjoying the fucking my wife from the rear for a another minute or two and the tongue exploring my ass as well. After a few more minutes I told them both load 2 was about to release and they both got on their knees in front of me and shared again the stroking and sucking off and on on my cock and balls until I exploded round 2 in both of their faces. Less volume at this point but still enough built up from the excitement to make both of their faces glisten. At this point I needed a smoke and a beer so we drank more and fucked around naked for hours. This was one of the nest, if not THE BEST sexual experiences in my life
I have had FMF threesomes before and enjoyed them of course, first was after what was supposed to be a simple game of strip poker with a young lady we'd known for quite some time, the young lady went to take a shower, naked and horny, we both got horny seeing the girl(25 or so) completely nude and did some heavy petting heard the bathroom door open so stopped. Of course this time she saw me I was hard she took a long look but said nothing, sat beside my ex and after a bit thighs were rubbed, a shy little kiss, not long before thing were very hot. After we were done, and I mean done, exhausted, my ex invited her to share our bed, and she did every time she visited after that. It was from her that I truly learned how to go down on a woman.
That said, even as a straight guy, I prefer two guys and a lady, can't explain why, but watching a cock disappear in a ladies mouth turns me on far more than seeing her bury her face between another woman's legs.
