I have had one MMF threesome thanks to this site.  It was wonderful, two men giving all their attention to one woman.  Because she was turned on, I was turned on.  Having another cock in the room was interesting.  Not that bi but when he was fucking her and my cock was in her mouth and he bent forward to kiss her and my cock got sandwiched between their lips, I thought that may have been the best part of the night.
