Azusa is a housekeeper who always works diligently. But her huge breasts catch the eye of her husband and son. The father and son take advantage of her diligent personality and make lewd requests of her, and Azusa responds to them. She is busy with other tasks besides housework, such as washing her body in the bath, being her son's masturbation material, and checking the state of his penis. Azusa shakes her huge breasts and feels great, and in the end, she even takes care of the neighbors she has invited to her house.
