Director Kyosuke Murayama invited a married woman he knew on a private filming trip. The casual day-trip plan convinced Rie (pseudonym) to join. 28 years old, four years into marriage, no children. Never having experienced a honeymoon, she longed for travel and took the bold step to go while her husband was away visiting his hometown. She had dated her husband since middle and high school, initially drawn to him as her senior, eventually marrying him. However, her husband had been so busy working to afford their home that he neglected family life, leaving her increasingly lonely and dissatisfied. Her bond with Director Murayama grew during chance lunch meetings at work, leading her to accompany him on this location scouting trip. Though uneasy about keeping the trip secret from her husband, she opened herself to the director's kindness and the excitement unlike anything her husband offered, seeking relief from her loneliness. Having only ever been with her husband, she writhed in ecstasy as this familiar man penetrated her for the first time. Her voice cried out, "It's so embarrassing... but it feels amazing! Getting filmed turns me on... I'm cumming!" expressing her overwhelming sensations.
