Ema participated in adult videos to help support her family's finances, which were sustained by her mother. While her mother was hospitalized, her stepfather discovered the DVDs and became aroused. He roughly fondled her body, slapped her buttocks, and forcibly raped her. Since then, under the guise of studying, he has repeatedly invaded her throat with deep throating, performed rimjobs on her anus, and restrained her hands while torturing her with sex toys. Her body grew increasingly sensitive from the daily assaults, transforming her into a shameful state where she could no longer live without her stepfather's cock.
