In this chapter, we learn that hisakawa has been flirting with the teacher's daughter, and that the teacher is afraid that he will be bitten by her if he does not stop the flirting. The teacher tells us that he has known this for a long time, but that hisakoa's "hisaka wa" is a "little danger ous" . He tells her to "swallow" after flirting with another sensei, and to rub her "dick" against him. He says that this is the first time he has ever looked at her "face" during sex, and he tells her that if her students find out that she is so dirty, they will not be able to judge her as a person. She tells him to "stop this instant" and says that she loves her daughter so much that she would do anything for her, even if it meant being attacked in class. She says that if she does not keep her son busy, he will grow even more dangerous, and she will have to protect him from "weirdo" people.
