Do you know why I kept you behind? Because you haven't been focusing on your studies. You have been paying too much attention to my rear. Let me help you deal with your lustful compulsions. You have to do exactly as I say. I may or may not allow you to cum. In this video, I tease you and show off my body while instructing and guiding your masturbation. I edge you a few times and decide at the very last moment whether to let you cum on my ass or not.
