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.
We repeated that we would leave in the morning and they departed after giving Mary a kiss and hug while she was still naked. One of the lads took the liberty to put his hand down to Mary's pussy and she parted her legs to allow him to finger her. As they left Mary got dressed and said that it had been some good unexpected fun and a nice surprise for both of us. I asked what they were like when they were inside of her and she replied that they both had surprisingly large cocks and they felt really good. Asking if I minded what happened and even asked if I had arranged the surprise for her. I could honestly tell her that I did not have anything to do with it but it was great as a non vetted surprise.
It was close to dinner time so we got the bar-b-q fired up and enjoyed a lovely mixed grill. Sitting there with a glass of wine a car pulled up and out came the two lads we had met earlier, as they approached us an older man got out of the car and came over to us. Introducing himself as the land owner he asked if he could join us for a drink. Mary got up and got a beer out of the caravan for him and let him sit on her chair as she sat on the ground. He did not take long to tell us that the boys had returned home with the story of what happened but he did not believe them, thinking that they had just made the story up. Mary looked straight at him and said that they had both shagged her in the water and made the most of her while they could. Looking straight at me he asked how long were we expecting to stay and I told him that we were leaving in the morning as agreed with his sons. He turned to Mary and said that he had an offer for us. Looking a bit puzzled she asked what he meant, his reply surprised us when he told us his story.
Apparently his wife and the boys mother had died the year before and that he had not had a woman since. Stating that his sons had described what she was like he wondered if we would be interested in staying a bit longer. Continuing with an offer that he thought we may be interested in as we seemed to be open about our sex habits. I asked what the offer was and he said that if Mary and I would return to his house and let him join us in a threesome his sons would hitch our caravan up and tow it back to the farm. I of course looked over to Mary and she said if you are as well hung as your sons she would be happy to stay a bit longer. We started to put the caravan back to towing readyness and hitched it up to their car for them to follow us. Before we left he asked if he could see Mary with her skirt lifted to get him excited before we got to his home. Mary walked over to him and lifting her skirt she reached for his hand and placed it at the top of her thighs. Taking this as a hint he started to rub her knickers and just before he got too excited she removed his hand and said wait til we get back to your place.
