For reference I'm a male with a female partner.

In FFM threesomes our favorite toy is double dildos, so the girls can play ball. We use our FunFactory Share double dildo the most for this.

With FFM I feel like one of the girls, there is lots of feminine energy, and the experience seems lighter, slower, and more touchy feely. I serve as the male standard bearer- pleasuring the girls with cock and attention- but it is not the macho experience I had once imagined long ago, of one man "taking" two women. It's a dance, in which I am conservative with my energy by being more sensual than primal, so I can provide for two.

With MMF it seems that the boys serve as the "toys," but we do sometimes use some blindfolds, lingerie, butt plugs and restraints to increase the spicy. The toys are used to up the initial erotic tension for my female partner and for the bonus male- to push the experience into a sort of fantasy realm. Like something out of a erotic novel.

With the surplus of masculine energy it is a ravishing experience- with my female partner as the focal point of lots of attention. Obviously the bonus male is experiencing his own ecstasy with the "gift" of a lovely woman. I sort of fill in the gaps, as the other two are in a deeper trance. I feel more like a coach partaking in a victory than the star player (and its a nice change). So it is a different sort of heady buzz and satisfaction. Especially since I do most the vetting and administrative set up, it feels like a job well done.

Ironically, I do not feel like the center of attention in either situation. But that is sort of my personality. I'm a giver, and I just want everyone to have a special experience- and through that I do too. For me both situations are basking in compersion, and it feels great both ways.
