Growing up, I was friends with this girl that lived next door to me. Her name was Rebecca, and we were close friends, but never boyfriend and girlfriend. I remember going through puberty I began to notice her more and more. We were both in the same grade, and she was only two months older than me, so basically we were the same age. We were both growing up, but I could never keep my eyes off of her. She was gorgeous. She had a nice hourglass figure and very nice shaped boobs that were not to big nor to small (probably B cup). I would often think about her when I masturbated and I was always hoping that she was thinking of me. We unfortunately never did anything sexual together but there was one night when I was sure she was masturbating.

When we were both 15 and in the 10th grade I believe, and I was about to start my nightly jack off. It was late and already dark outside. The way our houses were set up was my house was two story and hers was one story. They were right next to each other where I could see her window, but it was almost always closed with her curtains. But one night, I noticed that she had left it open. Her bed was against the window and I was able to see her laying on it. I did not actually see her vagina, but I could see most everything from the waste up. She was cute to look at, blond and a nice body figure.

I saw her laying there on her bed, she was wearing a bra and I think nothing over her crotch. She had her eyes closed and I could see her arm moving and she was making very sexy faces. This was turning me on a lot and I could not believe what I was seeing. I wanted to see the rest but I knew that would be asking for to much. And at one point she stood up, put her panties on, and answered her mom at the door for something. Then she resumed her position and continued to rub off.

Then, she lifted her hips up and I could tell that she was having an orgasm. Her face also showed it. Then she stood up and put her panties on and I guess she went to sleep because she turned the lights off.

Then I needed to blow my load now. I was very horny and I took off my pants and my penis was hard as rock. I began to stroke it until I came in like two minutes.

This was one of the best experiences of my teen life, and I did not even get to see her naked, that's how desperate I was.
