SOLO ROLEPLAY You spent the last year wanking in my class - studying human anatomy in a most inappropriate way, and I am NOT going to put up with your antics this year. So, to get it all out of your system, I want you to pull your cock out and stroke it for me. Don't you dare stop until I say you can, and when I do, you're going to cum on my ass, and then you're going to clean it up. That should rid you of any illusions the next time you're in class.
