Overview

An older brother has to stay home alone with his younger sister, Sumire, who is a high school girl. Sumire, taking advantage of her parents' absence, takes off her clothes and wanders around the house in her sloppy loungewear. Her erect nipples are fully visible as she wears no bra, and her hair peeks out from her shorts. The older brother, who has become lustful due to such unconscious temptation, devours Sumire's body while she is dozing, and even becomes jealous of her going out on a date and forces him to have oral sex with her. What is the sister's answer to the brother who can't be honest with himself?
