My Sister

I'm Daryl 56 widower, 2 grown children who have move to the city and married. I lost my wife Cheryl 3 years ago to cancer. I lived alone, then my only sister Dianne 49 came to stay with for holiday. She got divorced and wanted to get away from things for a while, they had sold their house and split the money. Both were working in finance industry at the time, Dianne was looking for a transfer at the time. To get away from her ex, as they worked at the same place. So while looking she came to see me her only sibling, we had always got well while growing up. I live on 25 acres and have 2 horses, chickens and 6 cows. I sold my business when Cheryl died, as we ran it together and I couldn't handle it without Cheryl too many memories. I'm fairly well off and just potter around my hobby farm. Dianne enjoys horse riding and we started to ride around my land. The second week of Dianne's visit on the Monday it was hot and while horse riding together, we came to the pond on the farm. I had put in a dam thirty years ago and Cheryl had landscaped it into a beautiful place. While sitting together under the trees, Dianne suggested we go swimming together, I said I haven't any swim trunks. She replied Neither do I, we'll swim naked there's nobody around. She stood up and started to undress, I decided to do the same. Soon we were swimming naked in the pond, after a while Dianne and started to sunbake on the grass beside. She is a little overweight, but still looks very good. I stayed in the water, as I had a hard on. She told me If I stayed in too long I would turn into a prune. Then I think she realised why I was staying the water, she got up and entered the water again. Came over to me, then I felt her grab my cock. I was shocked at her grabbing my cock, then she wanted me to get of the water so she could see my cock better. I agreed to get out and held my cock till we were both out of the pond. She said We should on our backs and get some rays. I done as she wanted and my still hard cock laid flat against my body. Dianne looked at it for a time and then got up and started to play with it. Stroking it and then going down on me sucking it, I warned her I was about cum and she kept sucking and then swallowed all my cum. I didn't say anything, after a few minutes she asked me If I had enjoyed it. I nodded and she smile saying If you want we can go back to the house and continue it there. I agreed and we dressed and rode back to the house. I had sex with Dianne and she slept with me for the rest of her stay. That was 3 weeks ago and last week she rang and told me she had a transfer to my area and wanted to know if she could stay with me. I said Yes, She will be back next week and I asked if we would have anymore sex together. She replied That the main reason she accepted the this transfer, instead of another that she was offered.
