A man and his wife are stranded on a desert island. The wife begins to lose interest in her husband and wishes on a star that she would find another man. The next day a man is washed on shore. He is very nice looking and finds immediate interest in the wife. The husband was very pleased that there was another man to help work.
So they started on building a watchtower. The stranger and wife wanted to have mad passionate sex on the beach. So he tried to think of a plan. SO then the stranger offered to watch first from the watchtower. While the husband and wife worked, the stranger yelled, "Hey! No fucking! Get back to work!"
At this, the couple yelled back, "We're not fucking!"
A little while later the man again yelled out to them. And again the couple denied it. This happened several times during his shift up in the watchtower, and when his turn was over, the husband took over. With that, the stranger made love to the wife on the beach. The husband, watching, exclaimed, "Wow, it really does look like they're fucking from up here!"'
