I had jacked outdoors before but this went to a level I still enjoy doing today.
One summer me a few friends and I went to a local elementary school near our homes that had a baseball field. We played some hardball for a few hours but it was getting near dinner time and everyone had to head home. One friend asked if I wanted to walk back with him. He had a bike and could have gotten home faster. I told him, no, you head home I want to knock some balls around into the backstop. He headed off with a weird look on his face, like I was crazy. Well yea I was. I was feeling really horny and wanted to jack off before heading home. I love doing it outside so it seemed like a good place to do it. I walked around the vacant school and finally found a spot that had some promise. It was in between two five foot juniper bushes next to a classroom door. Best part was there were windows across from me so I could watch myself get off.
I stepped into the opening between the two bushes and undid my zipper and pulled out my growing cock. I liked what I saw in the window so I decided to be a little braver. I undid my cut off pants and let them fall to my feet along with my underwear. Then I pulled off my shirt. Now here I am totally naked outside even my shoes were off. I looked both ways over the bushes and saw the coast was clear. Finally I walked out of my hiding place. I could be caught by anyone from three different directions. I had never been so aroused before. I have been hooked since then. I walked back to my spot and continued stroking my ample sized meat. I am one of those guys who like to hump on things when I come. I laid down on the warm cement and started slowly rubbing the warm smooth surface with my dick. After about a minute I felt that warm tingle in my balls and knew I was going to shoot a huge load. I slowed down and lifted my chest and stomach up so I could watch my cum spray out in long bursts. I squirted about six times and then just watched it slowly dribble out. Oh my god it was the hottest thing I had ever done up to that time. I got dressed and went home. I returned several times later and did the same thing.
By last count I have repeated this in different places over 60 places. All public. All nude. During daylight and night.
I am addicted I think.
