10 years since I lost my husband. Hiroyuki, the only son who has been raised by a single woman, has also decided to get a job at his uncle's company, and the mother, Sayoko, has finished raising her children. However, the peaceful days were short-lived when Hiroyuki made a serious mistake at the company. His uncle, Yoshio, visits the house and rushes at him, but the naive Sayoko cannot do anything about it. Yoshio, who was secretly aiming for Sayoko, started groping her plump breasts, saying, "My son's mistakes must be wiped away by my mother."
