Becoming a Bitch

I (47) inherited a house from a cousin who died of cancer and as I had moved in to help him after he got the cancer diagnosis, and he had no siblings or children he left the house to me. During his illness we got a puppy who kept him company while I worked, and the dog grew up and he was quite big. On the passing of my cousin, I was alone in the house with the dog, and he started hanging around me all the time I was home. As he was company for my cousin while I was at work, he was an inside dog never slept outside. That was how it was when I was sent on leave for a month, renovations at work so everyone went on leave. With little money for a holiday away and a dog to care for, I was at home the whole time. Being divorced and not on good terms with my ex and my 2 grown children rarely visiting either. It was just me and the dog, I took him for walks more often on my holidays. I do exercises on a mat on the floor to keep fit, due to being alone and I didn't bother wearing clothes while exercising as I showered straight after and decided to do all my exercising naked. I should've realized when the dog started sniffing me while exercising. But didn't, then one day he licked my pussy and at first, I told him to go away. He didn't he just kept licking and I started to enjoy his licking and let him continue. Finally, he tried to mount me, failing at first. But kept trying and I thought it funny, then he found my hole and was in me. I was then shocked and as before I let him continue to, he was finished. I realized I'd enjoyed his fucking of me, and it became regular for him to fuck me after I had exercised. Then with his cum dripping out of my pussy I would shower. That is how it is still today 10 months after he started fucking me, I'm still his willing bitch.
