Mizuki lives a happy married life with her kind and kind husband. However, Mizuki had one complaint. That is living with my vulgar father-in-law. She was tired of living with her stepfather, where sexual harassment was commonplace. One day, her father-in-law finds Mizuki who has fallen asleep while her husband is away. Taking advantage of her son's absence, she removes her underwear and devours his genitals, which smell like a woman's and sweat, and then forcibly cums inside her. From then on, Mizuki's young body continues to be polluted by her stepfather's beastly sexual desire...
