Last year, I (44) finally gathered the courage to tell my wife (46) that I was turned on by the idea of watching her having hot sex with someone else, or having a MFM threesome. She was really surprised and a bit shocked, but we are really good about talking things through without judgment, and after that we discussed it every now and then. She said she couldn't imagine sleeping with someone else, but she read articles and blogs about hotwifing, we added the fantasy in our sex life (just talk), and she started telling me when she found guys attractive. I should add that we have a very healthy sex life, we do it often and talk about it a lot.

It never got beyond that, but she did tell me a couple months ago that she could imagine actually doing it, in situations like if we're at party where we meet someone we both vibe with.

Now to the advice I/she needs: she is currently on a 3-week organized trip of a lifetime with her mom. Our kids and I had a video chat conversation with her, she's having a blast, the group is nice, all is good. After a while, she said she wanted to talk to me alone, so I moved to a different room. She starting by telling me how much she loves me and how hot I look on the screen, and then she said that she has a crush on another member of the group she's travelling with. She said she finds him very attractive, and she feels "giggly and blushing" when they interact with each other, and he somehow always ends up sitting next to her for meals. She shared a picture of him, he does look good! They go on hour-long runs together, and he often makes jokes or comments that make her think the crush is reciprocal. He's also married, lives far away from us, and she said she would have never allowed that crush to develop if I hadn't told her about my hotwife fantasy. I am not worried about this turning into an emotional long-running affair. I told her that it sounds a bit complicated since they're part of a small group travelling together, but that hearing her tell me everything was actually a big turn-on, and that I'd be ok if anything happened as long as she tells me everything.

I trust 100% that our relationship is not in danger, and I told her she should just be upfront when she feels that it's the right time, something like "I have to be honest, I have a crush on you, I've discussed it with my husband because he's into hotwifing, and I have no intention of leaving my marriage or having an affair when we're back home." We ended the conversation with my wife saying how much she appreciates our relationship and the fact that we can talk about anything, and how much she loves me.

Is there any piece of advice people with more experience can add? Anything she should make sure to say or not say? What's your take? I was worried I would feel jealous if a situation like this happened for real, but I am just incredibly turned on :D
