Thirty-year-old Ayaka is a modest wife suffering from daily household stress and a sexless marriage. One day, on her way home, she encounters a strikingly attractive man who catches her eye. Drawn to his presence and unable to resist any longer, Ayaka gives in and chooses to experience sex with a stranger for the first time. Neglected by her husband and starved of feminine desire, this encounter becomes a powerful new thrill. Her body reacts intensely to the first foreign cock she's ever taken since marriage, and the pleasure lingers long after she returns home. Though she intended it to be a one-time affair, Ayaka resolves to contact the man again herself.
