I seduced my stepson for sex while his exhausted girlfriend rested

I was hanging out with my friend and his girlfriend when I realized that she was completely exhausted. I decided to offer her a place to rest and that's when things got interesting. I started talking to her boyfriend and before long, I was seducing him. I told him that he was lucky to have such a hot girlfriend and then I started touching his cock. He was taken aback but also turned on by my forwardness. I told him that I wanted to suck his cock and he let me. It was an amazing experience and I could tell that he was really enjoying it. I gave him the best blowjob of his life and then we had sex. It was exactly what I had been craving and I couldn't believe that it had happened with my stepson.
