My step-son's step-father is coming home tonight. I ask my step-son for advice on what to wear. He looks jealous! We've been having a lot of fun together while his step-father has been gone. But that has to stop now. Of course, I had a lot of fun ... and of course I'm thinking about it now ... But it's not right. I'm his step-mother, and he's my step-son. No, we can't just to it one last time! Though I will say, my step-son has made me cum much harder than his step-father ever had. Okay, maybe I can just rub his cock one last time to remember how good it feels. Ooh, my step-son has such a perfect cock. I can't help but to put his cock in my mouth. I tell my step-son that yes, I'm going to have sex with his step-father tonight. That's what married people do. But I will be thinking about my step-son's cock inside of me ... thinking of fucking my step-son while fuck his step-father. My panties are so wet while sucking on my step-son's cock one last time. I have to climb on top of him and feel my step-son's cock inside me one last time. Oh my god, his cock is so big! His step-father's isn't this big, so his step-father is certainly going to be able to tell that something happened! My step-son is such a trouble maker! I can tell how much he loves being inside his step-Mommy's pussy. He's got me so close to cumming already. I cum so hard on my step-son's cock. I can feel my pussy juice dripping down his cock. I want him to cum for me. I want my step-son to cum for his step-mommy one last time. I bend over on the bed for my step-son and tell him to feed step-Mommy's pussy with his cock. He fucks me hard from behind. I can't take any more and tell him to cum for step-Mommy. I hope his step-father doesn't find out, but I can't help it. I need my step-son's cum inside my pussy. He fucks me hard and deep and empties all of his cum in his step-moms pussy. I sure hope his step-father doesn't find out that step-Son's cum has soaked up step-Mommy's pussy.
