I was in an FFM threesome at one point and it was great fun!!! The other women and I had an awesome time with the one guy!!! What we did was we like, took turns having sex with the guy, and the other one used a toy. Back then, I was like, bi, and so was the other girl, so all three of us were like, in the shower. Great fun. I'm straight now though, so I probably wouldn't do it again/
