Wife's First Time Fantasy Comes True... Sort Of

I was married to my wife for five years before I decided it wasn't working out and we should split up. It's not that she isn't great; she's fantastic, really. But when I found out about her secret fantasies a year ago during our anniversary dinner, they just didn't quite jive with me in the way I needed them to for a relationship. It all started when my wife mentioned how much she had fantasized about a threesome since we got married. I was okay with that; it seemed pretty standard and there were no hard feelings on either side. But then came her follow-up confession, she wanted it to be me plus a guy she knows, but who isn't currently in our lives. I just... couldn’t do that. It felt too much like an invasion of my privacy, and I wasn't really into the idea of bringing someone else into what should have been just us. So instead of doing the threesome, we went on a trip to New York City for the weekend as planned, but things started falling apart right after. We decided to give each other space. She went off with some friends and I stayed home. And then last month, while she was out, I found this note in her purse: 'Honey, if you ever want me to be happy again like before we met, come talk to him.' The name at the end made my blood run cold, it was our friend Ben. The thing is, despite how uncomfortable it makes me feel with what she wants, I do love my wife and want her to be happy. So last week, I went over to Ben’s place to discuss a potential roleplay scenario that could fulfill her fantasy without actually acting on it, CNC style. It ended up being more than just a talk though. She watched through a hidden webcam feed as we did all sorts of kinkier things she's been dreaming about for years. Afterward, I joined in from home and we had some hot phone sex together while they were still getting off. It was weird yet exciting; the kind of thrill you only get when everything is consensual but feels taboo. So here's my confession: Even though it felt wrong at first, seeing my wife live out her fantasies vicariously through me with another man made her happier and us stronger in a way I hadn't anticipated. And I hope she doesn’t regret letting me find a compromise that still works for both of us.
