One day, Shohei's father brought a beautiful young woman. Her name was Sanae. Eventually, Sanae and Shohei shared the same last name, and she became Shohei's mother. For Shohei, who lost his mother at an early age, he never got used to living with a woman in the house. It is also a shared life with Shohei and a beautiful woman who is not so different in age. The stimulus was too strong for Shohei. And that day will come. Shohei couldn't control his sexual desire, and he violated Sanae.
