Once feared as the strongest special investigator, Kana Morisawa left her past behind to live a peaceful life with her beloved husband. But one day, her husband's superior—claiming to have been taking care of him—suddenly appears at their home. This man is none other than the one who once arrested Kana and sent her to prison, a figure from a dark chapter she thought was over. Her past as an investigator is exposed, and her tranquil life shatters in an instant. Yielding to blackmail and threats, Kana is forced into submission and subjected to vile creampie rape. With her husband absent, she is repeatedly dominated by his throbbing cock, even in the bedroom where love should flourish—used like a toy while dressed in her investigator uniform. Finally, overwhelmed by a massive creampie load, her body is defiled by degrading semen, transforming the once invincible investigator and devoted wife into nothing more than a cumdump.
