After losing her job, Kana starts working as a housekeeper for a wealthy family. When her employer goes on a week-long business trip, she's asked to stay on and work from home. Spending a week alone with her employer's son, Takagi, Kana witnesses a side of him he's never shown before. He engages in lewd games, loses her belongings, slips her sleeping pills, and engages in sexual pranks. He then takes advantage of her mistakes and pushes her to become his submissive sex slave. Facing daily sexual servicing by a young man, Kana is forced to obey his perverted demands. Unable to escape, she's fitted with a collar and treated like a pet, forced to worship his penis. Further fueled by aphrodisiacs, she's driven to intense, eye-rolling orgasms and finishes with a powerful cumshot!
