Ryuji, a college student of marriageable age, can't get the voluptuous, busty married woman Yoko, who lives next door, out of his head. He fantasizes about her voluptuous breasts and ass that look ready to burst, and spends his days in agony. One day, Ryuji goes to Yoko's house, where Yoko is alone while her husband is away on a business trip, to share some pears he received as a gift. Yoko, who has noticed that Ryuji has been looking at her with lewd eyes, opens her chest and provokes Ryuji!
