My Step-Son snuck into my room while I was in the bathroom getting ready for bed, he was watching me for several minutes, he started playing with his cock in my bed as I walked out, I was shocked, he was rubbing himself and would not stop, I told him this was inappropriate behavior and to stop and leave, he didn't. I started to encourage him, I told him to be a man and pull it out and jerk off, he did. I started to get excited and wet, watching my Step-son jerk off in front of me, i had to help, I started to jerk him off, I needed to taste him and started to suck him, deep throating him, GAGGING ON HIS COCK. I'm getting so horny I need him to fuck me, I need him to pound me from behind and he did. I turned over and he straddled me, I wanted him to finish jerking off and cum for me, cum on my face step-son
