I work at a delivery company and get paired with Miho, a cool, strong-willed married woman. Our relationship starts awkwardly, but we gradually grow closer after I discover her gentle side. When I finally ask about her private life, she blushes and admits that her marriage has been sexless for seven years. Overcome with affection, I steal a kiss. Even my clumsy kisses and caresses make her sensitive body climax repeatedly, and from that day on I become completely obsessed with her.
