Yukari Fujisaki is an ordinary housewife who drives a used light wagon, constantly rushed by daily chores, child-rearing, and work. Since giving birth, she has prioritized saving money over beauty, living a life devoid of sensuality. However, at the family restaurant where she works part-time, she encounters a vigorous college student who hits on her, reminding her of the forgotten joys of being a woman. Though her mind tells her it's wrong, her womb aches with desire, leading her to indulge in an extramarital affair. During her break at work... while returning from shopping in a parking lot she is demanded... forced to become a bitch in the cramped car interior for secret, close-quarters car sex until the very last minute, multiple times engaging in bareback intercourse with internal ejaculation. She then rushes off to pick up her child, still carrying semen inside her.
