You were caught looking at porn and stroking during study hall. Since you’re a part of this school that goes for the respect to women and good behavior, you have to be punished. The headmistress calls you in and decides to try some alternative methods for getting your behavior to change. You’ll be stroking in front of her while she uses a tool on your balls and cock to remind you that you shouldn’t associate stroking yourself in front of people with pleasure. You have to learn your place and manners. Even though you are stroking and enjoying yourself that way, you never know when she will strike you and make you feel the thud of her implement. You’ll have to cum this way in order to break your masturbation cycle and prove to headmistress Tabitha that you learned your lesson.
