I was not quite 11. I went away to a summer girls camp for a month. I didn't want to go but my parents made me. I was dreading it and being away from home.
Anyway I really didn't know. much about sex but I knew how to make myself feel good and wet, and knew how rubbing my clit felt good.
When I got there I realized that a lot of the girls knew each other and had been there before and after the first couple days there was a group of girls who were very secretive and kept to themselves in their little group. After group activities they'd go off on their own. Actually it was about 8 of them. So after a few days I asked one of them what they were doing. A girl named Sasha said we could go with her but it was to be a secret and I could never tell anyone what they were doing. I agreed and after that days games she told me to follow her. She was with the others and said she had invited me to come along.
The others were ok with it so we headed off down into the woods. We walked for ages until we got to a really secluded area. One of them says, Let's start with Anya. I was confused but a couple of girls came to me and started removing my t shirt, shorts and panties. Another began touching me and as she did, I saw the others were getting undressed. I was really enjoying the feel of her fingers on my clit and got very wet when suddenly she slipped her finger in me. She paused for a moment taking off her clothes and then continued rubbing my clit. She whispered Do it to me. So I did. She was already wet and my finger just went right in her. We made each other come several times and another girl goes OK let's swap. Basically we took it in turns to finger each other. I had the best time of my life.
I probably don't need to add that we did this after group activates every day. It was the best trip of my life. After that I count wait for summer camp the next few years.
