I was invited to the home of a senior who was taking care of me. It seems that the senior is living a happy married life with his wife. He told me to drink as much as I could, so I decided to let him stay at my senior's house. Late at night, when he gets thirsty and goes to get a drink, he witnesses his senior training his wife as a masochist. When I woke up the next morning, my senior had gone out, and now that we were alone, his wife was seducing me with a strange sense of closeness, but it was all a perverted couple's plan...
