A perverted masochistic mother named Yuri has been thoroughly trained by her master, who she refers to as 'sir'. One day, he orders her to hand over her daughter Kana as well, threatening that if she refuses, she will be discarded. Determined not to lose both her husband and daughter, Yuri decides to comply. While Kana is out, Yuri seduces and sleeps with her daughter's boyfriend, then shows off her lewd behavior to Kana upon her return. Seeing her mother's submissive nature arouses Kana, who also shares a masochistic bloodline. As a result of their simultaneous bondage training, they become the ultimate mother-daughter whores... #elderP
