Sumire's long-awaited newlywed life changes completely when her husband's disreputable father moves in. He drinks from morning, watches porn at deafening volume, and gambles, making every moment alone with him miserable. Then he spies on her bathing and becomes obsessed with her pale, big-titted body. While her husband is away, the father-in-law storms into the bathroom and forces himself on her. Though she is devastated, her sensitive body responds against her will, and over time she begins craving the very man who violated her.
