Youth is overflowing with innocence, isn't it? This work portrays a clash between youthful energy and adult allure. The protagonist is Nabichan, a 20-year-old fashion student working part-time in the wedding industry, who harbors quiet anxieties about her future. With passionate sincerity and youthful charm, she actively pursues her partner, saying things like "I like being scolded" and "I want to get married soon," using her youthful words and actions to win his heart. Her presence radiates a pure, intense energy—like passionately learning and singing along to songs popular among young people at karaoke. In Route A, we see her gradually bonding with him, luring him with promises of model-like part-time pay, buying alcohol at a convenience store, then heading to a hotel. Holding a chuhai, she opens her heart, listening to his youthful troubles while offering both her body and soul. The overly talkative scenes are an inevitable choice. She's sensitive—her arousal heightens as she bares her emotions, though she may simply be naturally responsive. Once undressed, her toned, slender figure—reminiscent of a track and field athlete—emerges. Her shy expression when her partner pulls out his cock is adorable. At this sexually vibrant age, her pussy is soaked even before being touched, her innocent smile vanishing as she shifts into intense, breathy moans. As the adult relentlessly thrusts his cock into her, she becomes so overwhelmed she can't even scream. After a powerful standing doggystyle, she collapses onto the floor, completely spent from orgasm. Taking advantage of her dazed, unresisting state, he finishes with a facial, shooting cum onto her face. This is a compelling story exploring how youth and adulthood communicate—both emotionally and sexually—and how deeply these connections can run.
