A friend told Aoi that she could meet someone she liked using the XXX app. However, even without using the app, she started dating her boyfriend about a month ago. Today, she and her boyfriend were heading to Aoi’s house for a study session. As she opened the front door, Yuko, her beautiful and elegant mother, came out of the bathroom and greeted us with a smile. However, her lower body was drowned in sexual activity with a stranger. The next day, when Aoi came home and went to open her front door, a stranger approached her and showed her his phone, pretending to know her mother. As soon as Aoi saw the screen, she fell into a mind control. The man takes her to his room and devours her helpless body. After one attempt, Aoi wakes up. A strange feeling… Aoi’s brain is forced to alter her common sense and she is on her way to becoming a masturbator. Aoi’s body quivers with increased development and sensitivity, and she serves the man in a lanky manner, but not a trace of her usual dignified atmosphere remains. Meanwhile, Yuko also fucks her colleagues and patients in the dentist’s treatment room as a workplace-approved meat maid. When she returns home exhausted, she finds Aoi panting as a man fucks her from behind. Shocked, she joins in on her own, and mother and daughter transform into masturbating sluts…
