Strange Request

I'm David 65 answer to Dave, I'm single and no children. I live on my own property of 320 acres and have a few head of cattle 3 horses and chicken and a dog Bundy. I'm not a into crowds and keep to myself mainly. I'm not a hermit, I see friends and relatives all the time, but like my time alone. I've had romances and nothing came of them, except one and got as far as engaged to marry. But faith took a hand and and Jane was hit and killed by a drunk on a crossing. Red lights didn't apply to him, but he got a high price lawyer and got bale and drunk again and took a turn too wide and went over the edge and down over a hundred feet. The sudden stop at the bottom stopped his drunken driving for good. Since I've not been into relationships and move about at my own speed. Then in April I was asked if I would have liked to have a child and answered it was in my plans with Jane, but didn't last passed her death. Emma 39 is Jane's (deceased) niece and her parents are also gone beyond the vale as they say. I've known Emma for a very long time and can see Jane in her face. No close relatives Emma isn't much for the dating scene and prefers her alone time like me. But she also wants a family and made an offer to me of having a child for us both. Emma said she always liked me as felt sad at me losing Jane, who she doesn't remember much of, only being 3 at the time of her death. At first I thought it wasn't right, but seeing she looked sincere. I said I would think it over, but wasn't really interested at that time. I thought it over for a week and decided, why not as it would make Emma happy. I thought we would use I V F or I would just give her a donation in a jar. But Emma want wanted direct insertion and I said you want an old guy like me to fuck you. She replied its the way most babies are made and I think you should get some enjoyment out of it as well. I just nodded, but added I should get tested to see if I can get you pregnant. My sperm count was very good and with the test out of the way. Emma started to live with me at the end of June. She kept a check on her circles and we had sex every time it was the best to make a baby. Six times I fucked her and then she just started sleeping with me all the time. Then at the beginning of September she tested positive and we were both delighted. I thought she would return to another room after the positive test, but has stayed in my bed and still wants sex from me. Sometimes I call her Jane and she just gives me a kiss.
