I actually have told her how much I’d love to see another woman enjoying her body. I can clearly see it turns her on when we talk about it (typically during foreplay or sex) and she has told me it turns her on to see how turned on I get by the idea. It managed to ask what she would like to do with a woman, what she’d prefer. And she said she’d love to get her pussy eaten by both of us at the same time and she’s interested in scissoring.
The only thing I can see holding her back is her jealousy. She constantly tells me she wouldn’t want me to get turned on looking at another girl. I’ve explained I just want to see how she’d enjoy it and I wouldn’t touch the other girl at all. I’d let them have some fun and I’d jump in to finish the job but only with my wife. But she says in the heat of the moment she’d even encourage me to fuck the other girl but obviously regret it later.
So that’s where I’m stuck, convincing her she’d be the center of attention and I’m not interested in the other girl I’m interested in watching her get played with.
