My partner (38M) and I (40F) have a very happy sex life. I’m bi, he’s not. We’re both into the idea of having sex with another bi woman. I find the idea of us having sex with someone else very hot. Particularly he and I pleasuring someone together or he and her pleasuring me - he’s not massively into being the recipient.

What’s holding me back is a fear that it won’t feel like “us” having sex with someone and that I’ll struggle if/when he’s really into pleasuring her. He’s a pleasure dom and melts me into multiple orgasm puddles every time we have sex - I don’t think I would react well to seeing him do that to someone else. Is it possible to behave with different dynamics in a threesome than you have in your own sex life? i.e. will he be able to resist totally going to town on her?? Should I even ask/expect him not to?

Maybe I’m underestimating the pleasure I’d get from that or that I could be giving/receiving at the same time. Am interested to hear the realities of the dynamics when the M in MFF is a pleasure dom type.
