Kiho has lived with her husband's family of doctors for three years, originally hoping the arrangement would help their efforts to conceive. Instead, pregnancy never comes, and her obstetrician husband blames her while their sex becomes a joyless obligation. Lonely and anxious, she begins pleasuring herself, unaware that her father-in-law is watching. He exploits the weakness in both her heart and body, presses himself on her despite her resistance, and begins repeatedly creampieing her after she has sex with her husband.
