Bad Teachers Special Education

You're in detention...again. Your hot teacher is giving you a stern talking to but you can barely focus on her words as you can see the tops of her stockings and it's driving you crazy. She figures out your problem and decides that a 'release' is what you need to help you focus on your studies. She guides you in a masturbation instruction, encouraging you by revealing more and more of her figure, which you've been fantasizing about. It's a tease...can you hold out and cum exactly when she tells you to?
