Maho decides to work at soapland on behalf of her husband who does not rely on earning or libido. Two birds with one stone that can satisfy their sexual desire and earn money! I was enthusiastic about aiming for a signboard soap lady if I did it anyway ... Maho's body, which has lived with her husband alone until now, has been sexless for many years and has become completely ignorant of erotic things. In addition to that, there is even a handicap of inexperience. Maho turns her son into a practice table in order to overcome this high wall and become the number one soap lady.
