It's my birthday brat

It's my birthday & u have to do what I say because you're my little stepbrother. Stepmommy say that a little twerp like u has to listen to your big stepsister. If u don't do what I say, I will embarrass and humiliate u until u become my slave! Grabbing your cock, I'm going to squeeze it hard unless u jerk it for me. And if u don't stroke your cock, I'm going to invite everyone over so they can see you naked. Jerk it, little bro. You can't ruin my birthday, especially with that tiny penis. I thought you would be a little bigger because in this place, everyone is well-endowed. Maybe you got someone else's genes. Wouldn't it be awful if I called everyone upstairs to see your little pecker. What girl will like you if they see your itty-bitty penis? Does showing my tits turn u on? I'm bored so you have 5 seconds to cum. Counting down, you prove that your little dick makes little cum. You can't tell anyone about this or I will pull your pants down and expose your dirty secret.
