Former lingerie model Miki Mihama is a stunning 32-year-old newcomer with an I-cup figure and almost divine beauty. Though she seems untouchable, she is an ordinary homemaker trapped in the sixth year of a cold marriage and the second year without sex. Her beauty keeps other men at a distance, leaving her crushed by loneliness. Desperate to be held and loved passionately, she lies to her husband about attending a class reunion and arrives at a porn shoot for her first taste of infidelity.
