I was ashamed by my son's friend

When I went to Oishi's house. Yokota witnessed the appearance of Saeki's underwear, the mother of Oishi. It is a deceptively hidden stomach. Yokota is shocked by the appearance that is not related to Oshare. The defenseless underwear that was not supposed to be seen was much more vivid and erotic than the beautiful woman's underwear seen on the net. From that day, Yokota visited Oishi's house every time and began to steal Sasuke's undergarment. And, it was thought that only Saeki had the partner who dedicates the sadness.
