I remember another time in a naturist campsite. After having lunch and having a few drinks with some friends we went to our tent. My husband and I were so horny that we started fucking on the table we had in the plot next to the store. From the front you couldn't see anything because it was covered with curtains but we didn't realize that from the back everything was in sight. When we realized it, there was an old French couple watching carefully as we fucked.
