On a small corner of a street in Tokyo, a middle-aged man without a wife lives alone, he is heavily addicted to sex and very eager for sexual activities, but he doesn't have a girlfriend to "help" with his physical needs.
A beautiful girl from the countryside came to the city to visit her older brother and stayed at his place for a few days, little did she know that this trip would ruin her life.
After not seeing each other for a long time, the young man couldn't believe how much his little sister had grown. With full utilities and her beautiful face, his little sister made quite an impression during their first meeting.
