Riko, who had been living alone, was forced by her parents to share her home with her uncle Rikuto. Once confident and attractive, he now begged her for forgiveness with panties on his head. Despite his shameful behavior, Riko still found him appealing and allowed him to stay, even as her "pet." Curious and reserved, Riko, who often indulged in her fantasies in private, began giving him intimate commands, taking advantage of her period. Her "pet" eagerly obeyed, touching and pleasuring her according to her desires.
