My wife Ruisa, who works both at home, went on a company trip last week, but she's been acting strange since she came back. A few days later, I found a DVD in a drawer that my wife uses, with the words "Memories of the trip lol" written on it. Feeling suspicious, I looked at it and found a video of my wife, who was in an unnaturally high mood, being surrounded and played with by men from her company. I also saw my wife having a threesome with a colleague in a mixed-gender hot spring. I was filled with a strange excitement along with an immense amount of anger, and I couldn't stop watching the video...
