Mayu Okino, 18 years old. Moving to a new city for college, she begins living alone for the first time and enjoys a carefree university life. However, after a painful first sexual experience, she develops an interest in appearing in adult videos. Wanting to discover what truly pleasurable sex feels like, she steps into the AV industry. Surrounded by a large crew, she slowly undresses, revealing her translucent pale skin. When her pink nipples are touched, she blushes and smiles shyly; as her genitals are stimulated, she lets out lewd moans. The moment her first real pleasure arrives, a deep, overwhelming ecstasy she's never known before envelops her completely. The pure, innocent face of this beautiful girl is captured in raw, documentary-style realism. Her genuine reactions and the emotional depth gained through this first-time experience are the heart of this work's appeal.
