Our parents are making dinner, and my step brother and I are watching tv in the family room. I notice the outline of his cock through his shorts, and I can't resist putting my hand on his leg...I move my fingers up to between his legs, and I can feel him grow under my grip. I take his hard cock out of his shorts, and I put it in my horny little mouth. I hope we don't get caught, but I really want to taste him deep in my throat. I use both my hands and I really enjoy playing with him. I jerk him off until he cums in my mouth! It feels so naughty with our parents in the next room!
