This work portrays the daily life of a schoolgirl who becomes deeply involved in paid dating, neglecting her studies. Mizuki Yayoi is shown meeting a client who demands high-quality sex, and he performs a so-called "sensitivity check," stripping off her uniform and thoroughly examining her body, even checking the muscles of her pussy through her underwear. The inspection leads into her expert blowjob, making him cum in just one round, followed by increasingly bizarre sexual acts. Using aphrodisiacs and bondage toys, she brings him to repeated orgasms until his entire body becomes one sensitive erogenous zone. The climax arrives with raw, unprotected sex—hard, deep thrusting culminating in a creampie finish. This is an intense, intimate portrayal of her desires and obsessive attachment to her partner.
