A trip to a local park turned into something more.
My family and I had decided to join some friends at a local state park on a sunny Sunday afternoon. There is a nice lake to swim in there and my boys had already changed and gone in the water. After chatting with our friends I decided I should go get my suit on and join my sons. As I walked up to the changing rooms a group of teenage girls were coming out of their changing area. As soon as they saw me they instantly turned around and went back in while giggling. I didn't think much about it since teenage girls are always giggling.
I went into the changing area and sat down on the bench. As I was undoing my shoelaces I noticed that there were about five holes drilled into the wall between the girls side and the boys side changing areas. While I was thinking about maybe peeking through, I noticed that the light showing between the holes was being blocked out one at a time. I realized now why the girls had turned around and walked back into their changing area. I was being watched!
This was too much. I had never been naked in front of any women except for my wife and mother and now I had five girls peeking at me. I started to get hard right away. I decided that I would give them what they wanted to see. I made sure that my pants and underwear came off first. I'm not the biggest guy with a dick but I was almost 7 inches at the time. So here I am standing in the changing area with just my open shirt on and my dick as hard as stone. I slowly reached down and started stroking. They got more than they thought they would see. Well with my audience watching and me stroking slowly it didn't take me long to shoot a nice huge load onto the floor.
I sat down and squeezed out the last few drops just as a father and son came in the door to use the bathrooms. I quickly pulled on my suit and went out. Later in the water two of the girls walked by me.. They both smiled at me. They knew what I had done, but they didn't know that I knew what they were doing.
