Ai, who is the president of the PTA at her son's school, was thinking about putting on a performance at the school festival that was coming up in a month. It's a ``sex education booth'' designed to reform the classmates who are bullying her son. On the day when she received a GO from her teacher in an erotic way... she is a reverse bunny in a haunted house! Soap mat play in the classroom! Sex education worthy of the name of PTA president
