The collector is a virtuous wife to her husband, a sex slave to the doctor; a chaste wife indulges in a strange 7-day escapade of lust. (Hamabe Shiori, YMDD-453)

Completely depressed by workplace troubles, Sumire, at her husband's urging, goes to a psychiatric clinic… Little does she know, it's the terrifying clinic where the depraved doctor, Ozawa, uses treatment as a guise for lewd brainwashing and sexual manipulation… Daily, Sumire is gradually eroded, brainwashed, and manipulated, torn between her happy life with her husband and the pleasurable manipulation the doctor inflicts… Even at home, her perverse desires surge, craving her beloved husband's penis, sperm, and pleasure… Even after repeated ejaculation filling her vagina, she can't resist wanting more. On the other hand, she also begins to yearn to see Dr. Ozawa, her desire to be embraced growing stronger. Anxiously awaiting the doctor's enormous penis, she almost faints when it's inserted without a condom… She lets out a joyful howl as she's forced to become pregnant, becoming a perverted, lewd bitch experiencing spasmodic orgasms…
