Several months have passed since my mother lost interest in my father and left home. Being in a male-dominated family, he is unable to do housework, and his father, who thinks it is a problem, suggests hiring a housekeeper. A few days later, Maiko is dispatched from the domestic help center. Her brothers, Natsuo and Shun, couldn't hide their excitement at Maiko's motherly and sexy look. One day, Shun shows his older brother Natsuo something good, and his father and Maiko are there.
