Kanna lives with her husband and son who has reached adolescence. Starting from a certain day, her husband goes on a business trip, and the mother-son duo begins living alone. Then, taking advantage of his father's absence, the son starts clinging to Kanna persistently. Kanna also accepts this son, and naturally, their physical interactions escalate. 'Does my body bother you?' Kanna asks gently, guiding her confused son's erect penis to ejaculation. She then teaches him about the female reproductive system and even the method of making a baby... For several days while her husband is away, Kanna acts as a special sex education teacher for her son.
