At a hospital for infertility treatment, married woman Yuka finds herself surrounded by doctors who repeatedly subject her to sexual harassment. With her beautiful appearance and ideal body, she becomes an irresistible target for the physicians. They grope her large breasts and persistently engage in lewd acts, performing oil-based treatments and oral sex aimed at satisfying their lust. Ultimately, they proceed to intravaginal insemination under the guise of sperm donation therapy. As the doctors' desires spiral out of control, Yuka is gradually overwhelmed and pushed to her limits.
