Step-Mommy walks into your room without knocking and catches you comparing cock sizes with your friends. I try and look away but I'm intrigued. You boys ask me who's I like best. I insist that I need to try the cocks out first and get a closer feel. So I have you all line up and I take turns sucking all of your dicks. My step-sons cock is the smallest of the group and I tease him about that. I tell you and your friends my honest opinion about what I think of your dicks and then I pick my favorite one.
