Cooking, laundry, cleaning, and sexual services... Director Koichi Takahashi visits the scene to investigate rumors that married women working for a housekeeping service engage in sex acts upon homeowners' requests. Meet Ryoko, a 43-year-old housewife in her 15th year of marriage—cheerful, kind, and voluptuous, dedicated to her housework. While cleaning the floor, she's playfully teased by the homeowner, splashed with water, and invited to take a shower. After changing into workout clothes, she's asked to help run lines for a script. Unable to refuse, she gradually gives in to physical intimacy. She enjoys being licked, moaning blissfully from the stimulation, crying out loudly at the sensation of a penis, her face flushing as she reaches climax. After preparing and sharing a meal, they move straight to bed. Her vagina is stirred with fingers, sending her into ecstasy as her big ass sways wildly. She climaxes repeatedly, shouting "I'm cumming from your cock!" multiple times.
