I'll try to keep this brief - seeking advice so will try not to make it gratuitous. I'm still just aspiring to share my wife with another man, but am hitting a wall.

We're at the point of now talking more openly about it, and she knows that I want to try it and it turns me on like crazy.

We roleplay in bed, and use a blindfold, toys, audio erotica, tie hands etc.

Tonight, I tied and blindfolded her - led her through a scenario of another guy etc. She was really turned on and into it (incredibly wet, moans, spreading legs, responding enthusiastically to prompts like "spread your legs for him when you're ready" etc.)

The problem is that she likes to roleplay and fantasise it, but then when I said (mid session with her very engaged in a sharing fantasy) "so tell me what he looks like", she just replied with "well, you".

We continued, and she was really into it, and as 'he' was giving her head and she was building up to a very powerful orgasm, I said "Admit to me that you want another man. That you would give him your body to pleasure with my full acceptance and approval".

She then just kind of pulled back from it, and said "It's hot, but I'm just not sure that I even want somebody else - I just want you". I followed this up with, "well just pretend for me" and she went along with it.

Maybe I'm just being an idiot, but I can't work out what to make of where she's at. She's no prude, and isn't inexperienced. She is open to trying new kinks, but just seems to go along with things because it's what I want, rather than because she feels a burning desire to do them.

Can she go from this, to wanting another man to fuck her?

Anyone else been in a similar position?
