Collector: A faithful wife becomes a good wife to her husband, but a sex slave to her teacher. During these strange seven days, the faithful wife indulges in carnal desires. Shiori Hamabe YMDD-453

Sumire, a wife driven to despair by work setbacks, visits a psychosomatic clinic on her husband's advice… But little does she know, this clinic is a terrifying place, where the corrupt Dr. Ozawa awaits her. He brainwashes women, arouses their sexual desire, and subjects them to sexual training… Sumire, a wife slowly eroded, brainwashed, and trained daily, is torn between her happy life with her husband and the doctor's pleasurable training… Even at home, her perverse desires grow; she desperately craves her beloved husband's penis, sperm, and pleasure… Even with her vagina overflowing with sperm from repeated ejaculation, she cannot resist the urge for more. Simultaneously, her desire to see Dr. Ozawa and be held by him intensifies. She craved the doctor's incredibly thick penis, and when his unprocessed cock entered her, she nearly fainted... When he impregnated her and ejaculated inside her, she cheered and became a wanton, convulsing slut... This married woman was easily brainwashed, trained daily to fall into a hell of pleasurable caresses...
