Now that finals are over, Satomi "Sato" and Hinako are given a day off from school. After continually spending time with Sato, Hinako begins to feel urges of intimacy toward her for no apparent reason. Even though Hinako attempts to suppress these feelings, trying to not look perverted, she confesses her urges toward her on their day off. Hinako pleads Sato for comfort, and Sato responds to this by pleasuring Hinako until she is satisfied. [Written by MAL Rewrite]
