Kanako Narita works as a restroom cleaner at a large department store near the station. During her shifts, while cleaning the men's toilets, she gradually developed a habit of secretly gazing at men's genitals without even realizing it. Word spread about her behavior, and she became known around the area as "Kanako from the restroom." After three years in this job, her husband began telling her, "Don't come near me with that toilet-cleaning body," reducing their marriage to a sexless relationship. Now, she often masturbates in the women's restroom during work, fantasizing about male genitalia. One day, a young man catches her peeking at him and immediately overpowers her—ripping off her work clothes, roughly groping her breasts, and thrusting his cock inside before she can even react. But he isn't satisfied with just that. He exploits her vulnerability and forces her to come to her home. There, another man—appearing to be his senior—awaits. Her clothes are torn off, and she's bound tightly with rope and electrical cords. Though humiliated, ashamed, and desperate to escape, she can't stop the flood of arousal seeping from her pussy. The men misinterpret her wetness as eagerness, convinced she's turned on. Kanako is a 53-year-old woman who has lived seriously and diligently her entire life. She endured bullying in school but always pushed forward. Though her husband wasn't her type, she vowed to spend her life with him. Now, being tormented by strange men feels unimaginable—yet deep inside, she may secretly feel joy at being desired as a woman. The men take turns licking her body and assaulting her with their cocks. Her body responds before her mind can catch up, and she blurts out, "It feels good." Those words shatter all her restraint. Burning heat, throbbing need, convulsing with every thrust—she realizes her fate: as a toilet cleaner, she now exists as a flesh vessel, destined to service men's desires and cleanse them thoroughly. One after another, she accepts their thick, white creampie loads deep into her womb. Perhaps, in some hidden corner of her heart, the wife had always longed for this day.
