A major client requested a hot springs getaway, and I found myself with no choice but to go. The client, however, was a total womanizer. Even though we tried to arrange for a companion, his mistress was accompanying him. So, my sales representative and my colleague's wife were forced to tag along. As soon as we arrived, we were asked to change into our attire. The men wore yukata robes, while the wives wore more revealing outfits. We couldn't refuse, so we reluctantly changed and the party began. My client was in a good mood and everything was going well, but I received an emergency call from work and had to return. When I told him, he immediately became upset, so I had no choice but to leave my wife and my colleague and her husband behind. Relieved by the fact that my client was in a good mood and starting drinking, I headed to work. I finally made it home the next night. I hadn't been able to get in touch with my wife, and was worried, but she was fast asleep at home. I found my wife's belongings scattered around, so I was tidying them up when I came across an unfamiliar camera. I regret not looking at it now. The footage showed a wild party that took place after I had left, and a video of my wife being fucked.
