My Husband's Friend

I'm engaged to Mark and we're both in our early 20s. Last week, I went out with my friends and had a couple of drinks at the bar next door to their place. I met this guy there, Jake, who was really handsome and charming. We ended up going back to his apartment together. Once inside, he started kissing me, touching me, and it all just felt so right. Before long, we were naked, my body against him, our lips locked as fingers explored every inch of us. His cock slid into me easily, a familiar but illicit pleasure surging through me with each thrust. It was intense, fast, yet intimate in a way that made me feel both guilty and incredibly alive. Have any of you ever done something like this? What did it feel like?
