A dogs cock. I had a room mate who had an old hound dog. There was another dog in heat somewhere and he tried to hump anything that moved. I was pretty horny one afternoon and Kieth was working. So I got on hands and knees and called the dog. He mounted me right away. His cock was small and it was like getting jabbed with a pencil until he got it in. When he was finished I looked up and Kieth was standing in the door. I was his bitch the rest of the summer too.
