So you've been messing about in class? Well that just wont do. Your headmistress gives you a call and wants to have a word with you after school about your disruptive behaviour. When you arrive at her house, she greets you wearing a robe and drops a bombshell - your teacher has reported that you were laughing during sex ed class. Specifically, at words like "breast" and "vagina". She believes that your immaturity is down to lack of experience and decides that in order to desensitize you to these words, she's going to show you these parts. She tells you to jerk off as she demonstrates to you, showing her breasts and pussy before wrapping her mouth around your cock. She then asks you to fuck her missionary (POV) until you explode all over her breasts!
