What is my step-son doing in my room? He knows we can't be doing that any more. I told him the last time was the LAST time we were going to do that. It's not okay for step-mommies to touch their step-sons like that. It doesn't matter how much he begs me, it's not going to change my mind. He pulls out his cock and starts stroking. I don't care how badly he wants step-Mommy, it's not going to change my mind. I tell him to stop stroking ... but he is bigger and harder than usual. Is it because step-Mommy told him no? He's such a troublemaker. Well, we've already come this far. Fine I'll do this one more time, but he's getting too old for this. I stroke his cock until he begs me for step-Mommy's mouth. I get on my knees and put my mouth on my step-son's cock. It's already so big, I can't imagine how much bigger it's going to get as he gets older. Since this is the last time we're going to do this, I might as well pull out my titties to help him cum faster. He keeps resisting and says he's not going to cum unless he gets to be inside step-Mommy's pussy. No, I tell him we aren't going that far. But I've never heard so much begging before in my life. Since this is the last time we are doing this, I might as well let him be inside step-Mommy one last time. I sit down on my step-son's cock. His cock is so big that it barely fits inside step-Mommy. Feeling him fight back cumming makes me want to cum. I know he wants it too, so I cum hard on my step-son's cock. After he makes me cum, I know he wants some of step-Mommy's ass in his face. I turn around and ride my step-son's cock until we cum together. He shoots so much cum inside of his step-mommy's pussy. As we finish up, he thinks that he will be able to talk me into this again. We'll just see about that...
