This AV documents the illicit sex between amateur couples and actors, focusing on the emotional journey of the couples in a NTR (Cuckold/Cheating) scenario. This time, we focus on couples leaving love hotels in the Yen Hill neighborhood of Shibuya, known for its abundance of love hotels, searching for individuals with a cuckold fantasy... After approaching several couples, we had yet to find anyone with such abnormal sexual proclivities. Then we spotted a couple holding hands as they exited a love hotel. We approached them for an interview, posing as an adult internet show. The couple, he a government worker and she a hospital administrator, gave a serious impression. As the interview progressed, they revealed some unusual sexual preferences, like opening windows or tying hands... Sensing a lewd atmosphere, we asked for an interview at their home. When asked about the concept of 'cheating sex' featured in this AV, the boyfriend expressed interest though he had no experience. The girlfriend was hesitant but agreed if it was his desire... Thus began the cheating sex. Initially reluctant, the girlfriend's sexual desires were unleashed, and she became deeply immersed in intense pleasure, making it erotic!
