Long story short but I semi-recently found messages of my wife chatting with an old friend that was quite flirty, and she had even started sending pics in thongs, etc.

When I found them, I let her know about this fantasy for the first time. She didn't fully shoot it down, but said it was quite odd and not something she'd think she could do. However, she kept talking to the guy, and continued sending pics. He lives far away and they had made plans to meet up before he got sick and cancelled. She doesn't share these details with me, but also doesn't hide it too hard.

It's an odd position for me, I don't want to push the Hotwife stuff on her too hard, but I also know she wants to fuck this guy, but hasn't given herself the chance to do it yet. I'd be totally fine with her actually cheating too. Any suggestions on how to proceed?
