Fresh-faced college student Naiagara Syo, working her first job as a clinic receptionist, discovers her sexual awakening in the most unexpected of places. After a long day, her colleague Maki Kato, a seasoned veteran of the clinic's naughtier side, takes her under his wing. He tracks her down after hours, leading her to a nearby hotel where he gently coaxes her out of her innocence. Syo, claiming to have never climaxed before, is a ripe canvas for Kato's expert touch. He starts with a passionate handjob, feeling her up as she tentatively reciprocates. He then moves on to her tight, untouched pussy, licking and fingering her to her first-ever orgasm. Syo's moans fill the room as she experiences her first taste of pleasure, and Kato is just getting started.
