Ichihana, a female teacher who is about to marry her colleague Maeda. Because of that, Bob, a black janitor, has a weakness and is raped! Maeda sees the scene and is mistaken for an affair, and the engagement is unilaterally abandoned. During class in disappointment, crazy Maeda breaks in and turns Ichihana into a meat urinal with the students! Creampie! Squirting! "I'll do anything ... so get married."
