Living in company housing, Natsuki is targeted by jealous housewives after her husband's promotion. At a ladies' gathering, she accidentally drinks coffee laced with laxatives and can't hold it, wetting herself on the dining floor. The women erupt in rage, shouting, "Of course you'd soil yourself—such a disgrace from a mere employee's wife!" Forced to pay for costly floor repairs and cornered with no escape, she signs a contract to perform in adult videos to settle her debt, exposing her most shameful arousal. Crying under enema torment, her anus is relentlessly stimulated as an afternoon of anal humiliation unfolds.
