Hitomi Honda, a married office worker, finds herself targeted by her husband's colleague, Hosoda, a man she's always disliked. Ever since her days as a temporary worker, he's relentlessly pursued her with crude advances, and even after her marriage, his tactless and rough behavior hasn't changed. When Hitomi tells her husband she wants nothing to do with him, Hosoda overhears and flies into a rage, violently assaulting her. Though she defiantly insists, "I'll never cum," her body betrays her words as he repeatedly forces her to climax against her will. Caught in this sudden, brutal turn of events, Hitomi is pushed to the edge, mentally and physically broken.
