Awkwardly, we find ourselves in the middle of a conversation between a young man and his older sister. The young man, who has been in love with his younger sister for two nights in a row, tells his sister that he has been having sex with her for the past three days. He tells her that his nipples are getting bigger and bigger, and that his "dick" is getting stiff. He asks his sister to "rub rub" on his dick so that it "slips" and "sucks" . The girl, who he calls "Akira," tells the young man that she has told her how he feels, and the two begin to have sex. The younger man, whose name is "Nonoka," says that he loves her too, and they begin to kiss.
