A cruel confession left in a sudden resignation letter. A faithful wife, played by Furuhashi Mariko, has fallen prey to the clutches of a young new employee. Behind the scenes at work, unbeknownst to her husband, the two have been secretly making love, overwriting their love with semen. The video attached to the resignation letter shows the wife letting out lustful cries that she never shows her husband, dancing in ecstasy at the sight of her subordinate's cock. She is at the mercy of the new employee's youthful, powerful thrusts, and feels a sense of guilt as she allows him to cum deep inside her uterus. The despair of learning the truth about her wife who has betrayed him, and the irresistible eroticism that wafts from the video, destroy the husband's heart.
