When my sister and I were about 3 years old, we used to play with this 4 year old boy down the road. we used to play in the attic, while our parents were downstairs. One day he started talking, and telling us that is mommy said that he had a penis, and girls had vaginas. He asked to see hers, but she wouldn't let him, so he asked us. We were too young to know better, so we pulled down our underwear, and lifted up our dresses. He took off his pants too, and we stood there for a while, looking at each others privates. After about 10 minutes, he came over and started touching us. I remember it feeling really good, a little ticklish. We started laughing, and I started jumping, and making tons of noise, so our mothers came up to see what was going on, and they were totally shocked. My mother started yelling, and his mother spanked his bare bottom. We all started crying as they yelled at us, and told us that what we were doing was wrong. We never did it again after that. About two years later, our parents said that we could have a picnic in the woods. We went by ourselves, while they had tea together. After we ate, he asked us if we wanted to play a game. We agreed, and he said that we were going to play a game that his mummy and daddy called "Doctor". He told us to take off our clothes, and lay down. We did, and he started feeling us. He rubbed our crotches, and our chests, and then he started licking us. My sister started crying, but he said that it was alright, because he had seen his daddy doing this the night before. She calmed down, and he stuck his little willy in her, and kissed me. He started bouncing on her, and she started laughing, and he did it on me. It felt really weird at first, but then I relaxed, and he moved faster. Then he started moving down, and biting me. It hurt really bad, and I started crying. He stopped, and told us that he would never do it to us again. He told us not to tell any one, and we all agreed to keep it a secret. To this day I still have never told anyone. But a few months ago, I ran into him, and he asked me if I remembered what we did when we were little... It was uncomfortable, but I said yes, and told him that i thought it was really nice, and that I wish we could do it again. We ended up having sex, and Now I'm pregnant with twin girls...
