After years of marriage to a successful company owner, she has a comfortable and happy life apart from one frustration: because her husband only cares about conceiving a child, their sex is bland and mechanical. One day, her filthy, brutish father-in-law catches them having sex. Realizing how unsatisfied she is, he later attacks her while her husband sleeps. From then on, every attempt at baby-making sex with her husband is followed by her father-in-law secretly fucking and creampieing her again and again.
