I watched my wife get fucked by a 50+ year old man at a nudist beach. We go regularly, and being 22 she gets lots of looks and compliments. We sometimes fuck in the dunes. Sometimes we are spied on, which is a turn on. This time the guy was very forward and jerked off by us. When I came in my wife, he thought it was his turn , I guess he had done this before. My wife didn't move and just lay there, it was wild. I was so turned on by the fact she didn't resist. He fucked her fast on her back and came over her stomach.
We fucked again and went home. It was wild!
