One week my grandma wasn’t home. I went to her house to watch p*** in privacy. My grandma has a very big back yard with tall privacy fences. I have a fantasy of having s** in public, so i decided to do the closest thing to it. I brought my p*** outside, sat myself on the ground and jerked off outside. It added a little rush to it. I got bored and put away the p***, to space things up, I ran all over my grandmas back yard while jerking off. Then I came in a bush. I grabbed the hose and washed down the bush. That feels great to have said.
