I am very experienced in kink, however have no cuck experience, sissy, chastisty, dom and sub experience but never a cuck - even though it is a fantasy of mine.

My gf knows about the fantasy but nothing else of my lifestyle experience, we have been relatively vanilla. I introduced her to the cuck idea and she said she will "do whatever pleases me". I have played with a larger dildo in her a few times, and lightly talked dirty? "Do you like that?" - last time we did it I said "want me to invite a big cock over to fuck you?" while the dildo was inside and she said "yes" - I know she was in the moment and pleasing the talk - but I texted the bull I had lined up before instantly texting back saying lets wait when all of the (rush) feelings started to hit.

Now, as of today, I had mentioned both of us waiting until we couldn't bare the horniness how long could she make it before she was begging for it and she replied "a week" but "just thinking about you makes me horny" in which I replied yeah, I meant for the cuckhold fantasy I think if I got so horny I couldn't take it I would want it. In which she replied "we can try but I just think about you and want you" and I said "I know its more of a me thing, we don't have to do it" and she said me heart eyes with a kissy face..implying I don't think she really "wants" it at all. I guess this is fine to not want it, but do you think there is a way I could get her to do it AND not have regret or feel like she is being taken advantage of, just for my satisfaction, I really want it to be mutual and he "wanting" it or begging for it..which seems like it may never be the case.

CLIFFNOTES: My gf only wants to cuck me bc I want it and to do whatever would "please me" she has very little to no interest in it but agrees if I want it she would do it. Thoughts on getting her to "want/crave" it?
