I was just playing by myself over on the sofa and admiring my favorite yellow dress, when he tells me to come sit on his lap. But when I go to his lap he already has something in it. Something I've never seen before. I think it's his cock, and he's stroking it too! He tells me to sit on it, and it's so hard against my diaper covered butt! When I sit on his cock, I realize that I have a gross stinky fart, and I let it out all over his dick! My farts stink so bad, but he lets me push them all out, right through my diaper, and onto his hard shaft. I think he likes my stinky butthole, because he makes me take off my diaper and keeps asking for more!
