Caught My Ex In The Act

I never thought I'd see my ex-wife with another man like this. It was just a few days after the divorce papers were finalized. I was out for an evening jog and ended up near the old neighborhood, where we used to live together. I saw her through the window of a friend's house, a friend from back then, someone she'd always called every now and then. There they were in the living room, both naked, moving against each other. She was riding him, bouncing on top while he held onto her hips, guiding her down his length again and again. Her breasts jiggled with each thrust, one hand gripping the back of his head as she kissed him deeply. I watched from outside, heart racing but glued to that scene inside. I caught every detail: how she leaned forward at times, sliding off and then climbing back up until he pushed her away slightly and took charge himself, holding her hips firmly while driving into her with long strokes. She was moaning loudly now, eyes squeezed shut in ecstasy. I stood there for what felt like hours, but couldn't pull myself away. Even though we're divorced and I have no claim on her anymore, seeing this still hit me hard. The sex was raw, passionate, everything that used to be between us. Eventually, I forced myself to leave, knowing it wasn't my place anymore.
