I've made a house call, as your teacher, I want to ensure that you have the best chance at learning. I have noticed that recently that you are VERY distracted by the girls in class and especially by me. It's obvious you've reached that age when you're very horny. I'm going to teach you a trick, you can do before class, to help you focus. Being a good teacher I show you exactly how to jerk off and tell you how to use it as a tool for keeping yourself focus during school!
