One of my students has really been causing a lot of trouble in class. He can never seem to follow instructions. I decided to have him to my house for some private tutoring. Some... close instruction. I know if he can have the discipline to stroke his dick the way I tell him to and not cum until I give him permission (after a countdown of course) that he can learn to finally listen to me in class. He turns out to be an excellent student one on one, and with an excellent pierced cock. He jerks his dick just the way I say, stops when I tell him to stop, and cums so hard that it shoots into my hair! We won't be having problems in school anymore
