Here’s my situation: I’ve been dating my gf for two years and our relationship is fantastic, except sex is kind of getting boring. We live together, and last year a super hot Brazilian guy lived across the hall in our 2 bed apartment. She never did anything with him but she made comments on how hot he was and I agreed with her even though I’m 100% straight. Then I started imagining her having sex with him, we both know how much she would have enjoyed it. So as the recent months have gone on, I’ve been fantasizing about it more and more. Even though he moved out months and months ago the fantasy is still there.

We’ve talked about my fantasy a lot and at first she seemed against it but the more I’ve shown her how much I would enjoy it, she seems like she could grow to the idea. She then said it’s the buildup and planning that ruins it for her. She wants to do something that feels naughty, like spur of the moment.

But she also doesn’t want anything forced. Like she wants to meet the guy as a friend of mine first.

Is there a way to arrange this?
