You're entire class of students is failing and the principle has called you into her office to dole out disciplinarian action. After scolding you for doing such a bad job she notices you still don't seem to understand. She makes you drop your pants and kneel on a chair. Giving you a spanking that you aren't likely to forget any time soon. Once your ass is nice and red she pulls out a dildo. Fucking you in the ass to drive home her point. Be a better teacher or be called back into the principles office for another hard, ass stretching lesson.
