One day, a mother (Aoi) witnesses her son (Ataru) watching AV and masturbating. Knowing that her son can't get along well with women, her mother uses her body to try to build immunity to women, but... I'm worried about my son's caressing and sex caress, which only has knowledge of AV. From there, the mother's sex education for her son begins. And the son and mother, who are improving little by little, are matching their bodies many times.
