The campsite was a cow paddock on the banks of the river. We pitched between two large trees that afforded us privacy from the few other campers. The river was fed from the mountains and while only about 20 m across it ran fast and deep. Crystal clear, we had already seen two trout pulled from it by a grizzled old timer. In the late summer afternoon sun it was idllic. There were about three hours before sunset and with the tent up it was too early to start a fire and begin cooking. I put a few beers and a bottle of wine into a bag, and with some paracord, floated it out into the river.
"Its pretty chilly!' I remarked "We should have some cold ones in no time!"
My sister in law looked up as she set up her camping chair.
"Great, I'm parched. Why don't we join them?"
I look appraisingly at her and enthusiastically agreed. It was a hot day and it had been a long drive. A dip in the river would be just what the Doctor ordered. I stripped off, pausing for just a second when I reached my briefs and then dropped them too. We had spent several days in a tent together and privacy had not always been easy. I didn't think she would mind my nudity and the sun hitting my skin was glorious.
I looked up and saw her glancing at me and I couldn't help but feel the blood begin to head south under her gaze. Then she too shrugged off her clothes till she stood in the field proud and naked. We we both past our prime but she had fought back against the years and despite being in her fifties, six months of personal trainer as well as good genetics had left her with a body looking decades younger. Slender with small breasts she had a slight paunch still but to my eye that just made her look all the more beautiful. I turned towards the river as my penis started to betray my thoughts.
"After you then!" She said and I gingerly climbed down the bank and slipped into the water using the rocks for a footing. Sweet lord it was cold! The water was crystal clear and summer had done little to disguise its origin as snow melt from the mountains. The temperature wasn't the all of it though. The current was wicked and pulled at my body. I lowered myself down till the water covered my shoulders and as my breathing spasmed I held on to a large rock.
Seeing me safely in she followed. I looked up and had a beautifully lit view of her breasts hanging down as she bent forward and then as she turned to slip in, her round white bottom was inches from my face. I caught a glimpse of her pussy between her legs. It seemed puffy to me. Perhaps I wasn't the only one warmed by the situation?
She slipped a bit and I reached out to grab her shoulder. Touching her while naked for the first time felt like I had touched a live wire. Both of us stared at each other as we adjusted our footing. Swimming was out of the question with the current and we could only last a few minutes before the cold made our skin tingle. Time to get out!
She went first and I again let my eyes enjoy her now faintly pink untanned arse and that suspiciously still puffy pussy. I followed her and stood facing the sun to dry while my sister in law used a towel.
"How about some wine?" She asked as she pulled the towel roughly back and forth on her back making her small breasts sway. I duly grabbed some glasses and pulled the bag out of the river, filled both, and then went back up the bank. She was sitting in her moon chair facing the low sun and the towel was wrapped around her head. Kind of curious since neither of us had gotten our hair wet! She sat naked with one leg crossed over another. As I walked to her I could feel the weight of my now full cock. I handed her the wine and it was pointing straight at her.
