A young man offers to have sex with a pretty female public bathhouse owner who is away from her husband

Because her husband is used to working in an office, taking care of the toilet while at work is very difficult. Nao decided to help her husband fix the bathroom. But that's why the two rarely see each other. After her husband goes to work, he has to take care of his father, which is why Nao wants to have sex but can't. One day, Takahashi, a young boy who worked very hard, he constantly worked overtime and had to come home late, often locked himself in Nao's bathroom, and even though he was locked up, Nao continued to let Takahashi Go. After Takahashi fell asleep in the bathtub because he was so sleepy, Nao ran over and saved him, advising him to stop his work and come here to deal with him.
