At PH Highschool, the focus is on education. That education may be about sex, but that doesn't mean you should be masturbating in class. Shiri Allwood seems to have a problem keeping it in her pants during lessons and gets sent to the principle's office. It's something Principle O'Neill has seen before, students get too horny during lessons. So he gives Shiri a private and very special lesson. Stop masturbating in class, and if she can't control her urges, come see him and he will get her the fucking she needs.
