Spontaneous ejaculation SeXStoRY

It was many years ago, I think I was about 14 or 15 at the time. My friend Angela and I were just playing around when we decided to have a tickle fight. She was a fairly cute girl about my age that I had known for about a year. We both began to tickle each other, trying to make the other one quit. I don't know why, but I found myself getting really turned on by it. After a few minutes, Angela began asking me to stop, but I just couldn't help myself. I just kept on tickling her. Soon she was pleading with me to stop, but still I kept on tickling her. By this time, she was laying on the ground and I was sitting on her legs to keep her from squirming. All of a sudden, she let out a gasp and began pissing in her pants. When I saw the crotch of her jeans getting soaked like that, it sent me over the edge. I came so hard in my pants that I found it difficult to breathe for a few seconds. When my dick finally stopped throbbing, I was totally embarrassed at what had happened, and I know Angela was embarrassed as well. We both got up and went to our homes to get cleaned up. I never saw much of Angela after that, but I know I'll never forget that day as long as I live.
