Sounds to me that it’s possible she finds the whole idea intriguing. You said when you told her about your fantasies and dreams, “about my fantasies of her having sex and that I’ve had dreams about her with other men. She didn’t really say anything or react about it.” What exactly do you mean by, “ didn’t really say anything”, mean? Did she say anything at all, or make any type of gesture or any kind of sound? If she didn’t say or do anything thing after telling her that, then I’d say that’s a very good sign, not even including the comment she made after the show you were watching! All signs seem to be pointing in the right direction that she’s actually giving this some serious consideration, or has already made up her mind and wants to pursue this further. Considering that the vast majority of women, even if the idea turns them on, or that they too fantasize about it, don’t usually play along with accepting it so nonchalantly at the beginning. They usually get upset, or act like it anyway, but rarely don’t put up some sort of resistance. I think the next step would be to add it in the bedroom. If she or both of you drink, start out having some drinks wherever you choose, and without her being completely ......, but with or without drinking, get her turned on and horny and while you’re both in the heat of the moment, especially her, slowly bring up and introduce the subject of how turned on and excited it makes you, thinking of her being with another man. Emphasize that you have absolutely no desire to be with another woman, but just the thought of her really makes you hot! See how she responds while you talk to her and pay close attention to what her body is doing. Look her in the eyes and watch the expressions on her face, and of course, listen for any kind of sound she might make. Depending on how that all turns out, dictates where you go from there. Lets assume she didn’t object to anything that time. Then the next time, you just continue to add another element. Maybe start out with some role playing, watch amateur porn together so she can see just how common and normal it is, get her to talk about what she’s thinking or feeling. Tell her to imagine and fantasize that everything you’re doing to her, is actually another guy, and that you’re watching nearby, and that you just can’t believe how incredibly sexy, hot and amazing she looks from your view. Things like that, and what you want to happen, is to get her totally involved in every way possible.
