Naito, a perverted girl working at a bookstore, is discovered as a hyper-sensitive, full-body erogenous zone woman who can orgasm from kissing alone. She constantly indulges in fantasies, is deeply into BL, and especially aroused by scenarios where a sharp-tempered boy ends up as the submissive partner. She masturbates daily, multiple times without fail. Even without physical touch, she squirts uncontrollably, and exhibits shocking behavior such as sticking out her tongue and choking herself while climaxing repeatedly. Her intense expressions and realistic reactions captivate viewers completely.
