I finally told my wife I’m a cuck [cuckold’s perspective]

I [31m] have known I wanted to be a cuck for many years but have never admitted it. I have never pushed it with my girlfriend [30f] because she never seemed interested. Whenever I'd make remarks or dirty talk that hinted at others she'd always shoot it down by saying things like "I only want you and no one else"

She is very submissive and we have a free use agreement in place, I am her master and I have complete control over her sexually.

Recently, while dirty talking, the topic swayed towards her with other people, both men and women, and I admitted outright it was something I wanted.

And this time she had completely switched perspectives, saying she had been thinking about it recently because she knew it was something I secretly wanted.

She told me she'd consider doing it if I wanted her to be used by others for my enjoyment or for her to make other people feel good (she enjoys giving people pleasure, such as oral, rimming, even if she doesn't get anything in return)

Our entire discussions about it have been framed as still a dom/sub dynamic, rather than it being more humiliating seeing her with other men because her husband can't satisfy her, or similar dynamics that I see on here.

She would never be seeing bulls alone or even having 1-1 communication by texting, calling, etc, I will still be in charge of everything. She would likely be wearing a mask and/or blindfold as she knows and wants it to be about her serving and being used rather than her hooking up with other men.

I have no idea if we will go from fantasy to reality, but the option is on the table.
