Retired to small town on acreage

At 55 I left my career and the city widowed and to have a peaceful life in the country away from noise and large numbers of people. Was very successful during my career, likewise my late husband. Not short on money and was happy to try another lifestyle and maybe write a book. Not really, but it kept the busy bodies from asking me too many questions. My children fully grown and with own families and their own children would visit mainly at Christmas. I would only be 50 miles away and could visit anytime I wanted as well. Having bought an old farm and had it done up to suit me, I moved in and settled into my new life. In April 2022 and kept to low profile mostly not ready for new friends at that time. By July I started to mix more with the locals and made good friends. On a visit to my family, I and they found a stray dog on the street, and he was very friendly. The dog catcher who arrived shortly after said he would probably be put down as large dogs weren't preferred in the city. I decided I had the space and made arrangement to get him, he answered to any name as long as it wasn't said loudly. My granddaughter 5 called him Bucky and so it became his official name and after a time the only name he answered. I got back to my home and Bucky was with me and enjoyed his new home straight away. There was a fence around the house's yard, probably to keep out the farm animals. But I had kept it, and it would keep Bucky from wandering off. But he stayed close to me and was allowed inside the house with me, and I found myself talking to him every day. He is a very good listener and could sense visitors arriving before I saw or heard them. Friendly with everyone who visited, except at night. But visitors at night were rare, but I realized he was a good guard dog. He would sit with me during the day and sleep beside my bed at night. When family visited, he played with grandchildren and was sad when I left for home. With the grandchildren all wanting him to go with them, I'd realized Bucky was a great family dog and grandchildren always asks about him on their phone calls to me. I was working in the garden and Bucky put his head under my dress and licked my pussy. I was shocked at first and told him to stop and he did. But later he sniffed me and stopped on being told not to. This was how it was for a couple of weeks; I did masturbate every now and then. I was watching a movie, and it was rather raunchy, and I got a little aroused. So, I started to feel myself up and Bucky came over and started licking my panties while I had a hand in my panties. For some reason I removed my hand and let him keep licking me and I really enjoyed it. I decided to remove my panties and let him lick my pussy directly. I enjoyed that even more and final got down on my knees with my dress pulled up and to let him do what he wanted. I don't think I thought he would fuck me, but he tried to mount and failed a couple of times. But then he found my pussy entrance and was in me. Fucked me hard and I was really enjoying it, after he had his fill, and I was quite satisfied myself. Next morning I was ashamed of my actions with Bucky, but after a while just dismissed it as a one-off event. Several days later I let him fuck me again and then again, finally I realized Bucky was my lover. He knows only to try for sex when I'm alone and I like being his bitch.
