Married for 25 years, recently Reiko has felt uneasy as her husband started paying more attention to his appearance. As he began going out more often, she grew even more suspicious and decided to tail him secretly... only to find him meeting up with her friend! Shocked, she continued following them when suddenly she bumped into her friend's husband, Nakata, who was also tailing them. Following the two heading to the hotel, we enter together… Then, while eavesdropping in the adjacent room, the two are overcome with frustration and sexual desire. Might as well, we end up having sex too…
