Wife Eimi lives in a detached house, waiting for her kind and caring husband, enjoying what seems like an ideal married life. However, a name that keeps coming from her husband's mouth casts a dark shadow over her heart, stirring deep guilt. That name belongs to Oki, her husband's boss—a despicable middle-aged man who exploits Eimi's vulnerabilities and repeatedly rapes her. Every time her husband innocently rejoices on the phone, saying, "Thanks to Chief Oki, I landed a new contract!" Eimi's soul trembles, and her body once again falls under Oki's control. His fingers stroke her most intimate areas, his grotesque desires thrusting into her womb, bringing fresh waves of pain and pleasure. Her everyday life crumbles with just a single word from her husband, as Oki's presence continues to dominate both her mind and body.
