My son Shinya's friends who often come to stay are secretly attracted to his mother Yumi. One day Takanori who accidentally witnessed Yumi's masturbation attacks Yumi and has sex. Another night, Yumi approaches again, but Michio also participates and tastes Yumi's abundant body. When my son goes to the training camp, he gradually asks the young people who reach the orgy 3P himself and gets excited violently.
