A summer adventure surprise for us while camping. We decided that it was time for us to hitch up the pop top caravan and go off travelling for a week or two. With absolutely no plans of any sexual meetings we set off to warmer interstate destinations. After the first few days of travelling we found a site to stop at. Setting up the caravan and after a coffee we decided to patrol the area and see what was around. A short walk of about two hundred meters we came across what appeared to be a nice swimming hole. We thought about how remote it was and decided that as there didn't appear to be any other travelers around that we could go skinny dipping. So we stripped out of our clothes and like a couple of kids we ran into the water. The feeling of swimming absolutely naked was great, and I kept looking at Mary just to see her beautiful large breasts floating on the top of the water.
Bringing back memories of our younger years we were frolicking about and giggling heaps. We had probably been in the water for about twenty minutes when we heard a voice calling out to us. Looking up I could see two guys on the bank and said hello back to them. Then as we were looking we noticed that they had found our pile of clothes. They appeared to be either late teens or early twenties and as they approached the edge of the water they shouted to inform us that we were on private property. The noise we were making had been noticed by their father and he sent them to ask us to leave. We agreed that we would leave first thing the next morning as it was getting quite late. They agreed but there would be a price to pay, on enquiring what the price was one of them said that they could see we were naked and that they wanted to join us. We agreed and they undressed and came into the water.
Once they got closer they could see Mary's breasts like two floaties and both made their way towards her. On reaching Mary the older lad told me that the price to stay had just increased. Asking to what? they said that they wanted to play with Mary and that I should go and get dressed. I told them that was not a problem as long as they did not hurt her, they agreed and told me that I could watch from the bank to make sure that they didn't hurt her. I left the water and got dressed to sit and watch what was happening. As I looked at Mary I noticed that one of the lads had moved around to the back of Mary and had his arms around from the back and was playing with her breasts. The second was standing in front of her and I noticed him lift her legs up putting them over his shoulders. Listening to Mary it was obvious that with her legs up he was penetrating her pussy under the water and she was enjoying the attention being given to her.
I watched as they changed places and repeated the first performance. Once they had finished they started to lead Mary out of the water back to me. Telling us that Mary was a fantastic woman and glad that they were allowed to have fun with her.
