This came about because she was dancing with this black guy the other Saturday at a club. While i was at the bar. I saw her and she just looked like she was so horny. Like grinding and he had his hands all over her. His arm was around her waist pulling her into him. Whispering in her ear (I like to think that when my back was turned while ordering the drink that they kissed but who knows?) I stood there for what gelt like ages watching my girlfriend dancing more sexually with a stranger that she had ever danced with me. It was mesmerising watching the way that their hips and bodies moved together. It seem so in synch. Watching his hands exploring her body as they danced and her accepting it. I had never seen her like that before. I had seen her dance with other guys before but that was more like dancing 'next ' to a guy rather than 'with another guy.

He backed off as soon as I appeared. We went back home right after. She was really horny on the way home and couldn't stop rubbing my cock through my jeans in the taxi.

We fucked when we got back. She was so wet and her eyes were closed the whole time (which is not normal) so i think that she was imagining him. I could see in her expression that her mind was not on me. I then couldn't help but imagine what she might have been doing with that black guy if she had gone home with him.

Ever since then i have wondered what he said to her when he wss whispering in her ear.
