The Granny next door.

I live in a quiet neighborhood and nothing much happens at all. A month ago I was hurt at training and was had to stay home to recover. Usually there is no one home at our place during the day even on weekends. I sat quietly looking out at neighborhood, I could see the street and out a side window I could see into our neighbors home. Grace 60 something lived alone and we rarely interacted. Nothing happening at first then one day I was sitting and looked towards Grace's home and saw her completely naked. This was a shock at first, but nothing compared to what happened next. She got down on all fours and her large black dog mounted her and fucked her hard. Over the following week I saw her doing the dog everyday. I haven't told anyone else in the family.
