19-year-old beauty school student Kurumi faces her first shoot. Despite her gyaru appearance, she's been mostly abstinent for the past two years—a pure girl at heart. When she masturbates alone, she enjoys watching prank-style AVs. Having experienced pranks herself, her innocence becomes clear as she shares stories of her first time. The man savoringly explores her youthful, tense body with his tongue. When he asks, "What's happening to your nipples?" she answers honestly, "They're hard..." Her tight, youthful skin, tender and sensitive, emits cute moans as it's thoroughly licked. Turning her big ass toward the camera, she gets her wet pussy licked out in a crawling position, her expression shifting. Gazing slightly downward, she cries out loudly as her vagina is stimulated with fingers, squirting fluid as she climaxes. "I'm cumming—going, going, cumming!!!" she screams. After her first orgasm, her inhibitions vanish, and she repeatedly splashes her arousal. Obediently taking the cock offered before her, her pure, earnest demeanor shines through. She bravely stuffs the huge dick deep into her cheeks, highlighting her innocence. Then, with a nervous expression, she waits as the massive cock slowly pushes into her inexperienced pussy. He starts moving back and forth, gradually loosening her tightness. She screams sweetly from the pleasure of the giant cock. "Ah! No!! Aaaaaaah!" She braces herself against the window, moaning lewdly. The modest beauty student turns her face away from the window, perhaps from shame. Yet in stark contrast to her emotions, she's repeatedly penetrated in vulgar poses, creating scenes where her purity and eroticism intensely intertwine.
