Engaged but Not Tamed

I've been engaged to my boyfriend for two years now. We planned our wedding and I thought everything was set in stone. But a few weeks ago, we were at a friend's party, and she brought along this older guy, in his late 30s, I guess. It turns out he was a friend of hers who works as an escort. I had been feeling stifled with my fiancé, like the spark wasn't there anymore. So when that guy hit on me at the party, I gave him the number for our hotel room and we ended up hooking up there. It was intense, rough even, he dominated me in ways I never expected or thought possible. He tied me up and used restraints, but it felt liberating instead of scary. We went all night until early morning, and while part of me knew my fiancé would be devastated if he found out, the other part just wanted more. I haven't told anyone yet, not even him. But I don't regret a thing. It was a moment of pure freedom that reminded me there's still so much to explore beyond our engagement plans.
