Chased by a perverted detective, the truth of her affair is exposed... She is threatened, tied up, and repeatedly penetrated, gradually awakening to the pleasure of masochism. Office lady Nozomi slowly transforms into a woman consumed by lust. Fingers are thrust into her anus, making her tremble in pain, while her nostrils are toyed with, causing her to writhe in humiliation. As increasingly lewd assaults continue, she is punished with an enema, screaming in agony as it gushes from her anus, begging for forgiveness. Each act becomes a step forward on her path to sexual transformation.
