Kurosawa Nachi is a housewife troubled by her massive breasts. Her J-cup, 116cm bust overwhelms her daily life, leaving her bored and even nauseous. Her routine masturbation gradually increases. Amid her mundane, neurotic existence, this film reveals the deep-seated, pure sexual desire of a frustrated woman. By briefly glimpsing into her mind, we see that what she seeks isn't mere eroticism, but the joy of living with massive breasts, her voluptuous, fleshy body, and the irresistible, raw truth of a truly erotic woman. That is the allure of this work.
