Located in a city in the Kanto region, this company was a typical "family-owned business." With the father as president, the sons as employees, and the stepmother as a director, the whole family worked hard every day.

The stepmother's allure and her gentle encouragement of the depressed son eventually became the trigger for the forbidden "incestuous office" sex.
