This is my first time telling this story to anyone.
When I was thirteen years old my older cousin would watch me while my mom went to the store. My cousin was sixteen years old and we always had fun together one time my mom needed her to watch me while she went to work.
We were alone in the house she decided to watch t.v. I was in my room. I found a magazine that had a girl in a bikini I got aroused and started to masturbate, this was the first time I ever masturbated. I wasn't sure how to do it so I was not getting much pleasure from it.
My cousin walks in and say's 'what are you doing'. I was so humiliated I couldn't say anything. But she surprised me by saying let me show you how to do it. She told me it was better to look at a naked girl while you masturbate. So she took off her clothes and told me to touch her. I touched her breast then her pussy. I got real hard touching her she started to stroke my penis first, she did it slow then she stared to stroke it fast until I cummed. She made me promise not to tell anyone in our family about this and I haven't told anyone this story until now.
