fucking a nympho

It was a hot Saturday afternoon. I was at my in laws for a brief vacation. My wife had gone shopping with her sister. My MIL Lisa and her husband George were in their bedroom, probably enjoying an afternoon delight. I was in the loft area flipping through a local newspaper. It was a long boring day, my mind was numbed with the mundanesess of the day. In that thoughtless moment, George walked up the stairs into the loft. I saw just sweaty forehead emerge up the flight of stairs. I waved at him and went back to the newspaper, assuming he was there for something else.
