It seems like you've been having some trouble focusing in class lately. I think I know exactly what you need to help you relax and get that focus back. Have you been fantasizing about me in class? Is that what's making it so hard for you to learn? Take a deep breath and let Miss Wystri tell you exactly how to stroke your cock! Stroke for me, edge a couple times, then I countdown and tell you to cum hard for me. Hopefully now you're feeling much more relaxed and ready to pay attention in class! We just might have to make this a regular thing, I don't want your grades to suffer!!
