I'm Cheating On My Wife... But It's Not What You Think

So I've been with my wife for a few years now and everything was cool at first. We had this big romantic wedding, honeymoon in the tropics. But over time things just kinda... settled down? I don't know how to describe it. Nothing really wrong happened, but our sex life became predictable. The same old routine. Every day feels like a repeat of yesterday. But then, uh, I met this girl at work... She's married too and we've been chatting online for months now. It started out just as friends helping each other with projects. We're both in tech. But one night she messaged me something that kinda shocked me, she said she needed to talk about her marriage problems. I felt bad but I didn't know what to say... Then she asked if we could just vent about it, not really expect answers or anything. So we started talking more and I found out she has this thing for roleplay. She wants to act out a scenario where she's the wife cheating on her husband. And here's the weird part, it turns out I have this kink too. Maybe my marriage made me realize I wanted something different, not necessarily from my wife but just... somewhere else maybe? We did some research together and then one day we finally decided to do it for real. She was in her twenties and I'm thirty now. I showed up at a hotel with everything planned out, clothes, scripts, even toys... It felt so wrong but also exciting. When she got there, we just sat and talked for a bit, making sure this was still okay, that it wasn't about real cheating or anything. Then the roleplay began... She acted so convincingly sad to be with me when her husband couldn't satisfy her... We didn't rush into the physical part right away. There were long moments of just touching hands and kissing gently before we got undressed. It was more emotional than I thought it would be, she looked at me with such longing... Then she took off my shirt, ran her fingers over my chest, teasingly slow... She straddled me on the bed, pressing against me as we both slipped into the scenario fully. Her breath came faster and hotter against my neck... We moved together in ways that felt like discovery again, not routine. We didn't stop until hours later when we had to. The emotional connection felt real but it wasn't her husband I was with, there's no denying who I am now. When it ended she looked at me differently and I knew I'd never be the same after that night...
