In this chapter, we learn that Yura has begun going out to "hostess bars" with an older man. Yura keeps denying this, but the narrator tells us that he saw her leaving the hotel with the man. The narrator is shocked to learn that his sister is going out with a woman who is a "Hostess girl" . He tells his sister to get out of his room, but Yumi grabs him and tells him to "stick out your tongue" and "stick it out like a woman like me" , which is a reference to the fact that she will do everything he asks of her. He's shocked that she would do such a thing, but he doesn't want her to divorce him, so he begs her to do it for him. Yumi says she'll do it, but she's not sure if she wants to or not, so she grabs him again and asks him if he wants to "forget all about this" if he does it for her. She asks if he'll "keep looking like that" and he says yes, and then she puts her hands on his dick, which makes him even more excited. He asks her to "just do it" and she hesitates a bit, but finally opens her mouth.
