In a corner of a high-rise business district, married woman Yuki (pseudonym) quietly stood in front of a designated building. At 35, her marriage had become sexually stagnant, and with past experiences of infidelity, she sought excitement and decided to appear in an adult video. After preparing breakfast and sending her husband off that morning, and once her child left for school, she made her way to this location. In front of a complete stranger, she grimaced in embarrassment as she let out a small stream of urine. Led around by the man and stared at with scornful eyes, her humiliation gradually transformed into pleasure.
