This work features a play video published in an SM magazine's editorial department. The protagonist is Kikue, a company president's wife who has never been involved with any man other than her husband. Falling into a trap set by her younger sister, Mitsuiko, she is captured by her brother-in-law Ryo, a sadomasochism enthusiast, and forced into a life as his sex slave. One day, while returning from delivering something to her husband's company, she is summoned to a hotel. Called out during daylight without wearing any underwear, Kikue grows aroused from embarrassment and anxiety, her nipples erect as she approaches her brother-in-law. In this state, her nipples are toyed with and her anus is touched, eventually leading to her being verbally degraded as "filthy" before being given a shower enema—an intensely erotic and tense sequence unfolds.
