Born in Tokyo, Fumi Kimura (31) worked at an advertising agency after graduating from university. She later quit her job to marry and now lives a peaceful rural life at her husband's family home. While she is content with her daily routine of helping with farming and enjoying her handicraft hobbies, an impulse to "shine once more as a woman" led her to appear in an AV. Trained by a man other than her husband and pierced by his cock, this good wife opens the forbidden door to the thrill of immorality.
