Young man! How dare you have that little dick out under your desk! Look at you: pants unzipped, underwear pulled down, dick hard. What a pervert we have here, class! Everyone look at him. Oh yes, feel free to laugh. He should feel so ashamed and embarrassed. We'll have to teach you a lesson, won't we? Go ahead, jerk that dick while everyone laughs at you. I'm going to make you take your little mistake to the natural conclusion if you're going to insist on playing with yourself. The whole class is going to countdown until you cum all over your desk! After that, I'll have you clean it up with your mouth. This will be a lesson you won't soon forget!
