Miyuki, Harumi’s sister, and her husband gather at their parents’ house to celebrate their mother’s third anniversary. Miyuki is relaxing at her parents’ home because her husband is arriving late. Harumi’s husband, Ippei, stares at Miyuki with a jealous gaze. The panty line appearing from her skirt, her defenseless appearance after bathing… And Ippei, unable to control his lust, devours the fast-asleep Miyuki. Afterward, Miyuki’s body gradually feels pleasure as Ippei repeats his lewd acts even though her husband joins in and the family is gathered.
