Aya is a housewife living a boring life. One day, on her way home from shopping, she sees a sign for a "call massage" on a utility pole. She decides to call one because she's tired from her daily life. At first, it's just a normal massage, but gradually the massage starts to stimulate her erogenous zones. Frustrated, Aya extends the massage even as time passes and becomes addicted to erotic massages.
