Sakura has been married to her childhood friend for two years and desperately wants a baby, but her husband has little interest in trying—or in sex at all. Their rare encounters are rushed and nearly devoid of foreplay, leaving her empty and steadily cooling her feelings for him. When she learns he will be home late, she begins meeting a man from an affair site and repeatedly cheats. What starts as a way to ease her loneliness turns into a hunger for stronger pleasure, eventually leading her to volunteer for a porn appearance.
