Back when I was 13 years old I was over at my 14 year old cousin's house for the weekend. It was Summer time and we were in his room talking. My uncle was at work and my aunt was working in the yard. I was wearing shorts and sitting in a chair with my legs pulled up in the chair facing him. He was sitting on his bed. He kept looking down as he sat there and then started rubbing his hand between his legs and started telling me how good I looked. I didn't know what he meant and just kept sitting there. I looked down at his hand and then I saw what he was rubbing on. He was rubbing his hand on his penis and it was all swelled and big. I knew about boys and erections but had never seen one. Here through his shorts I could most definitely see one and was amazed at how big it was.
He continued and told me that he needed to 'get off'. I asked him what he meant by that. He answered me with 'I need to jerk off because of looking at you'. I had heard about boys 'jerking off' themselves and knew girls excited them just like they excited us in the same way. I had been masturbating for over a year. I continued to watch him rub on himself. He finally asked if I wanted to see 'it'. I told him yes. He made me promise I wouldn't tell anyone about this which I did and then took off his shorts. It was so big to me. He then told me to keep sitting like I was and started jerking off. I watched and he then kept telling me to watch him 'come'. I watched and got to see my first of now very many 'cum shots'. I have long since learned that boys love to have girls see them when they shoot off there cum.
The next day we were alone again when my aunt and uncle went to the store. We again went to my cousin's bedroom and did things again. This time I also took off my shorts and we touched each other. He showed me how to jerk him off and I showed him how to get me off with his fingers. This was the start of several years of us getting together and doing this to each other.
When we got older this ended but the lessons we learned 'playing' with each other sure came in handy with later relationships. I know my experience sure did and I'm sure the same can be said for him. I've certainly loved getting boys off and now my men friends and also love seeing them 'get there rocks off' showing off there cum shots. They all sure love doing this.
