27-year-old Reiko has been married for three years. Initially, her marriage was happy and harmonious, but after her husband was transferred for work and began living separately, she started feeling lonely. One day, she unexpectedly reunited with a male friend from her school days while out in the city, and the two ended up having dinner together. Spending time alone with a man again after so long made her feel excited and joyful. They drank heavily, and eventually ended up spending the night together in a love hotel. After that encounter, her long-suppressed sexual desires were suddenly unleashed. She began growing interested in meeting men through dating apps, craving more pleasure and seeking greater excitement—ultimately deciding to participate in adult videos.
