I was invited to the home of my senior from my university days. He is married to a wonderful wife and seems to be happy. We hadn't seen each other for a long time, so we got excited talking about old times and it got late, so I decided to stay the night at his house. When I woke up the next morning, my senior had gone out. When we were alone, his wife strangely seduced me, and I couldn't resist, but it was a plan by the senior couple...
