Their long-awaited married life took a dark turn when her husband's father moved in. Sumire's world, and her body, were irrevocably changed. Her father-in-law was a degenerate, spending his days drinking, watching obscene videos at ear-splitting volume, and gambling whenever her husband was away. Sumire found herself tormented by his presence. One day, she was caught bathing by him, her pure white, massive breasts catching his eye for the first time, sending him into a frenzy. Before long, he barged into the bathroom while her husband was absent and brutally raped her. But instead of despair, Sumire's body reacted with surprising sensitivity, and before she knew it, she found herself craving her father-in-law's touch.
