With long hair, an intense gaze, and a love of good waves, 35-year-old Mia Kuroki makes her porn debut. She has been married to a company owner for five years, but his frequent nights out have left them drifting apart. They now have sex only two or three times a month, and Mia wonders whether he does even that out of obligation. After admitting that the best sex of her life was an affair, she seeks the genuine pleasure her routine marital sex no longer gives her.
