My son Masao, who has never even talked to a girl, spends his days masturbating every day to relieve her loneliness. Her mother (Nozomi), who was worried about her son, found out that her son was a virgin and what she couldn't do, and confirmed Masao's technique with her own body so that she could somehow do it. However, she gives sex education from scratch to Masao's sex, which is too messy due to watching too much AV.
