While her husband is away on a long business trip, married woman Soma Akane has her nephew Kenji staying at her place. Though he feels guilty toward his uncle, Kenji is secretly thrilled to be alone with his aunt. His daily ritual has become sniffing her used panties—a habit born not just from curiosity, but from twisted longing. One day, as he furtively indulges in the act, Akane catches him in the act. In that moment, Kenji whispers inwardly, "Goodbye, my first love," preparing himself for rejection and humiliation. But just as he begins to drop into a dogeza bow, Akane gently kisses him, setting off an unexpected turn of events. As the Milf gives in to her desires, she becomes an aggressive seductress, riding him hard and demanding creampie after creampie. Later, she teasingly milks every last drop of his cum using her freshly removed panties, her big ass swaying with satisfaction.
