Five years after his mother died, his father, Saburo, decided to hire a housekeeper. The mischievous brothers Hikaru and Toshiro agree with this, and Rieko is immediately dispatched from the Housekeeper Center. Rieko is perfect at cooking and cleaning. Then, one night, an obscene voice echoes from somewhere. When the two of them follow the voice, they witness Rieko having sex with her father in a Japanese-style room. The two of them took a picture of the scene and decided to make her Rieko a vaginal cum shot pet from the next day.
