On the weekend, my wife and I decided to go back to our hometown to visit my father and stepmother after a long time apart. Because my wife had urgent business, I went ahead alone and she came later. Everyone is very happy, gathering together when there has not been such a large number of opportunities for a long time. Everything went very normally until night fell, and when we heard a strange sound, my wife and I were curious, so we went out to look and saw my father and stepmother having a very intense relationship. My wife's lust began to rise, just as we were preparing to rain outside the door of the room when we were discovered, instead of criticizing him for peeking, my father had a very crazy idea: to incest together to experience a new feeling.
