Oh...MFM are always fun for me since I get to be the F between two M's. :) Between, or under, or beside, or on top.

Since I'm a woman married to a bi-man the MFM is what we enjoy. I remember our very first time with another guy. For his birthday I got someone to join us--he was cute, younger and curious about BDSM. I remember bringing this "boy" to M's house and he basically ran right past me to check the guy out. He approved. :)

The most memorable thing of that whole scene was that every time I looked at my partner he had a huge grin on his face. I had never been a part of a threesome before but knew from that point on that this was something that would may my partner very happy. It also makes me happy because not only can I get a little extra attention but so can my man!

One of the hottest sexual situations I was ever in involved me being with my ex and another guy. She knew him really well so was ok with him barebacking her and I got the pleasure of licking her clit and his balls after we had both cum in her. As he came they were both twitching and our mixed cum dripped down his balls and I got to lick it off. VERY hot!!

Would love to find a fluid bound couple to do something like this with again...

Yeah definitely my favorite. Well, MFMF foursomes are good too. But I've never really been too caught up in the FMF fantasy that most straight guys seem to be into.

I've done the MFM with my wife and another guy a few times, but much less often have I been the extra M with another couple. That's a scenario I'd like to explore more...

They are hot and wonderful. The few experiences I have had have been with very bisexual men and the women said they loved they we were not just focus on her but also each other. It was a truly mutual sharing.

both my husband and i were swingers when we met - and still are :) and we are both bi and somewhat sub - but even tho im bi i really dont like to share a guy (or guys with another babe) so my BEST 3 somes are MFM ... i know others may prefer something else - also i have found that BI guys can sometimes be a lot more fun that str8 guys in a MFM - ive just found that a lot of str8 guys dont want another guy around when theyre going at it - i dont try to analyze why thats so its just been my experience....

Yes they are!
From one angle, it sort of takes a couple of guys to keep it up for the girl.
From another DP is just plain FUN!

We've played with both straight and bi guys and clearly much prefer bisexuals. Top/bottom, dom/sub doesn't much matter and we've had fun with both. I'm a top and co-topping is a gas. Topping another guy to MAKE SURE he treats my partner CORRECTLY OR ELSE, has always had great results too.

Straight guys mean one part of the equation is missing and the focus is two guys pleasing a girl rather than two people playing on a third. It makes the roles much more rigid.
