Kanna enjoys a comfortable married life with her kind and caring husband. However, she has one major problem: living with her father-in-law. He is crude and tactless, constantly making sexual remarks and harassing her without restraint. Kanna grows increasingly disgusted by this situation, silently harboring deep resentment. One day, while her husband is away, Kanna falls asleep at home. Her father-in-law discovers her unconscious body and, taking advantage of his son's absence, quietly pulls aside her underwear and greedily devours her sweat-drenched, feminine-scented flesh. He then thrusts his cock deep inside her, ruthlessly claiming her with repeated creampie rapes. From that moment on, Kanna becomes his repeated victim, her young body continuously defiled by his relentless assaults.
