Sumire lived a comfortable married life with her kind and considerate husband. However, her biggest burden was her father-in-law. He was rude, inconsiderate, and repeatedly made sexually harassing remarks and advances. Living under the same roof as him gradually filled her with disgust. One day, while her husband was away, Sumire dozed off. Seizing the opportunity, her father-in-law approached, pulled aside her underwear, touched her skin, and aggressively thrust his sweaty, pungent penis into her. He forced a creampie rape upon her, leaving Sumire with a new emotional and physical scar that night. From then on, the father-in-law continued to defile her young body whenever he found a chance. Enduring this torment day after day, deep inside, Sumire began to yearn for something—anything—to save her.
