When I was 13 I saw my older brother masturbating. We were watching tv one night and he thought I was asleep on the couch across from him.
It was the first time I ever saw an erect penis as well as a boy masturbate and ejaculate. I remember peeking and hoping that he would not see me and keep doing it. I knew that boys did it but I had never seen more than a bulge in his pajamas.
He was laying down on the sofa and when he ejaculated he stopped rubbing it just before it did and I saw it shoot out first and then he rubbed it more and shot more came out he was breathing real hard.
I never saw him do it again but I think about it alot and want to masturbate when I do. I would like to watch him again and give him a hand job, but I am too scared to ask.
