In this chapter, Ruchi begins to hate sex on his first day of living with his sister. He tells Tatsu to be honest and tell him why he made him cum. Tatsu tells him not to worry, because he'll make him rub it and make him suck it. He also tells him to slap him if he tries to stop. When Tatsu slaps him, he screams and slaps. Then he slaps Tatsu again, and Tatsu screams that he's been having too much of a time with his friend. He then asks Tatsu if he can call him back the next day to ask about kotoha. This time, it turns out that tatsu's sister has invited him and his friend to hang out at her house. He's glad to hear that, because it'll be awkward for him to be there.
