Showing off for younger girls.
I have loved being watched masturbating ever since I got excited by the girl across the street and exposed myself to her. Also, a few years ago I found a website where girls were on cam pretty much to watch, and some of us had mics for sound too.
I was looking for girls to watch me stroke off and found not one, not two, but three 13 year olds in a room together who told me they liked to watch. I asked them to give me a second.
My pants came down and I lubed up my cock. I then put the cam on my cock and started masturbating for them. Their eyes got big and I was so excited and they were, too.
I was stroking my lube covered cock in front of these three girls! I was breathing hard from such excitement, my stiff boner stiffer than ever. I said I'm going to cum and one of them said, yay! And that did it. I spurted a huge load and they giggled and laughed and said wow! Then, as though it could even be more exciting for me, one said eat it! And I raised my cum filled hand to my mouth and licked it up. She said, hell, yeah! And I smiled and they did too, and I had just eaten my own cum in front of three hot 13 year olds. It was just amazing.
