Sumire is a married woman who has been supporting her husband, who runs a small local factory. Recently, the business has taken a downturn, reaching a dire point where he can no longer pay his employees. One day, a metal plate at the factory falls on her husband, seriously injuring him. Hiroshi, one of the employees, comforts a devastated Sumire, giving her a glimmer of hope. Desperate to resolve their financial crisis, Sumire borrows money from her brother-in-law, Sagawa. When he demands sexual favors in return, she hesitates. At that moment, Hiroshi is caught shoplifting at a store owned by one of Sagawa's associates. In front of Sumire, Hiroshi pleads for forgiveness. Sagawa blames Sumire, claiming, "This happened because you couldn't even pay your workers," and threatens Hiroshi, shouting, "Do exactly as I say or I'll turn you in to the police." He forces Hiroshi to strip naked and then commands him, "Go on, suck him off," coercing him into giving Sumire a blowjob. Sagawa's humiliating games escalate, and Sumire slowly begins to break down. Two intense 30-minute spanking scenes unfold, delivering an unforgettable spectacle. Ultimately, Sumire descends into madness, desperately craving Sagawa's massive cock, bringing the story to its climax.
