The Neighbor's Dog

I'm widowed and at 62 live alone my children visit during holidays otherwise I'm alone. Last year I got new neighbors, and they were always busy in their mid-thirties always going somewhere and same with their 2 children. They have a large dog, more for security than a pet I assumed as it was fed but never played with. Anyway, the dog found a weak spot in the fence and got into my yard. I had spoken to him over the fence a couple times, and he was quite friendly towards. He was playful and so I played with him and didn't ask my neighbors to fix the fence. He became the highlight of my days at Christmas my neighbors were going away for the holidays and were going to him in a kennel, I offered to care for him, and they accepted the offer. It saved them money and I had my friend for 2 weeks. My children visited me twice Christmas day and New Years Day, otherwise I saw nobody else. I was down on my knees looking for pen I had dropped, and the dog started sniffing me and then tried to mount me. I thought funny and didn't tell him to go away. After failing to mount me, he put his head under my dress and started to lick pussy thru my panties. At first, I was shocked by his actions, but I recovered and was enjoying his licking. Suddenly, I decided I would remove my panties and give him better access, I really enjoyed the licking then. I got back down on my knees with my dress pulled out of the way. He started licking again and tried mounting me again. He failed a couple of times, but finally found my glory hole and really gave a fucking. Well at first, I was shocked he got into me, but really enjoyed it and it became regular for him to fuck me. Anytime my neighbors go away I look after their dog and when they at work or school he is my most welcomed visitor.
