The day I went swimming with my family in the summer. My son, Tetsuro, accidentally looks into my mother, Mitsuko, who is peeing in the shadows. Tetsuro couldn't forget the excitement at that time, and since then he couldn't help but want to see his mother pee. Thinking through it all, Tetsuro buys a diuretic that he found on the internet and gives it to Mitsuko when she comes home, making her go to work in the garden.
