Brat student gives teacher handjob

Look! I fixed my tie! Is this detention really necessary? It seems a little bit harsh to me. Look at how tight it is. Oh, it is a little bit loose. Sorry, sir. Let me fix it, and once I do, may I go home? There... that's better. Surely detention can be done now. Why are you fidgeting? I can see you doing something. What are you doing? Are you masturbating under the table? You can't do that in front of me! I can't believe you're doing that. Stop touching your cock. That's gross! Ah! I just had an idea. How would you feel if I told you to wank your cock, sir? I'll do it if you agree to let me leave detention early. After all, I could tell people what you're doing. I'll bet I can make this experience even more exciting. Have you got any idea what I'm about to do? Let me take over!
