What is my 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 mommies to touch their 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 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 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 Mommy's mouth. I get on my knees and put my mouth on my 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 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 Mommy one last time. I sit down on my son's cock. His cock is so big that it barely fits inside Mommy. Feeling him fight back cumming makes me want to cum. I know he wants it too, so I cum hard on my son's cock. After he makes me cum, I know he wants some of Mommy's ass in his face. I turn around and ride my son's cock until we cum together. He shoots so much cum inside of his 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...
