A cei, blackmail, self-suck. I'm a teacher and call you into my office after class. I'm tired of you not paying attention, looking at my tits and ass, and now caught cheating on a test. I threaten to tell the principal and get you expelled, you insist you'll do anything. I tell you to strip naked and sit on the couch, start jerking and that you can't cum until I say so. I slowly strip and tease you then reveal your real punishment is going to be eating your own cum. I instruct you to put your legs behind your head and keep stroking with your cock by your face. It's close enough to touch your mouth so I have you suck your own cock until I give you a cum countdown and you blow your load into your mouth. I snap a photo of you as you eat your cum and blackmail you with it. If you misbehave anymore, I will show the entire school.
