It was so hard to control myself when my stepson and I hung out the other day. He invited me to his dorm for a movie, but one thing led to another once he put on a porn video. It was a bunch of sexy twins playing around with older men. I didn't know my stepson was into daddy's, but I always hoped he was. He was as hot as the guys in the video. Now that we were sitting together watching these boys whore themselves to dad, I decided to take my chance. Watching boy after boy sucking cock was turning me on. I looked over, and my stepson was touching himself. I went down and sucked his cock before getting to his ass. We fucked over his bed until I unloaded on him, like the dads in the video.
