27-year-old married woman Sachiko arrives at Shima Shiko's inn, transferred there at her husband's request. Dressed in a business suit, she enters the inn as instructed—without panties. As a greeting, she performs a blowjob, but then is told, "You're allowed to take control," leading to immediate bareback penetration right then and there. Her actions signify not just obedience, but the beginning of a new relationship. All eyes are on how her life at the inn will unfold from here.
