Sumire, a masochistic pervert mother, has been trained by a man she calls "Master." He commands her to submit her daughter, Hinano, as a slave. For Sumire, obeying her Master's orders is more important than her daughter. She happily hands over her daughter. During her daughter's absence, Sumire seduces her daughter's boyfriend, indulging in wild sex. Hinano, who inherits her mother's masochistic nature, witnesses this and her perverted side blossoms. Eventually, both mother and daughter are simultaneously bound and trained, becoming obedient slave daughters. #YoroP
