I'm a sub for my husband, but I am a Domme for a couple of men. One of them is married. They are swingers, she knows her husband and I have had sex, but it just recently that he shared with her that he is my sub too. Since then she has expressed the desire to have a session with me, me acting as her Domme. She doesn't want her husband to participate or watch however. I'm trying to decide whether to do it or not myself. I don't want to make waves in their relationship.

My guess is that hubby is a cuck waiting to be used by you and your Dom.

I agree, if your husband is already acting like your sub then he will most likely fall into the sub/cuck roll very easily. The best thing to do is talk to him about it.

Not exactly the same - but similar I believe. My wife and I have had this secret relationship with one of my friends (who she adored physically I later found out). Several times over the past year I had set it up so she was blindfolded during sex and I quietly snuck him in to take my place. At first he watched but quickly came up to speed and slipped in and took my place. Watching my wife being satisfied like that was unbelievable, and she was always incredibly aroused and did everything imaginable. She never knew the switch took place, but after he learned what really did it for her it started to get really hot. Even after the fact that she had told me how physically attracted she was to him, I was still worried about telling her about what had been going on. I was also worried about the threesome dynamic, and how she would respond to me watching her having an orgasm with someone else. When I told her, it was the first time I had ever seen her blush embarrassment - but turns out all my worrying was for nothing. We made love on the spot. Turns out sex between her and I have never been better. We've actually had him in for a threesome several times since with her in total control. I never imagined that, like myself, she loved the thought of me watching her with another guy. Good luck.

Thank you all for your replies. My husband is not a cuck for now but he might become one if I push the right buttons. Truth is that I enjoy what I have with my Dom at the moment and I wouldn't want to risk to put that in jeopardy making the two of them meet. The punishments, spankings and all the naughty things you don't usually have in a normal relationship make the sex explosive most of the times. Is there anyone out there in a Dom/sub relationship with someone that is not her/his life partner? And if yes how do you make the two coexist pacifically?
