When I was about twelve, I would always go to a friend's house called 'Johnathan', and spend the night. Johnathan had a sister, Whitney, who was ten, Johnathan was also my age. He and I would usually sleep in his bed, and his sister would sleep in her bed, which was the next room over. He told me that his sister had the biggest crush on me, I really didn't think anything of it.
One night he said that we could sleep in the guest room, because it had a king-size bed. It was about midnight, and his parents had already gone to sleep so he and I were talking, we had dared each other to sleep in the nude, I had done this before, so I really didn't think much of it. There was quite a thunderstorm outside, so his sister wanted to come in the room with us. At first he said no, but then I finally talked him into letting her. She didn't know that we didn't have anything on, because we were under the covers.
Now this bed was huge compared to us, she was in the middle, I was on one side, and Johnathan was on the other. We decided to go to sleep because now it was about 12:30am. It was pitch black in that room, I couldn't even see my hand in front of my face. Johnathan was tired so he went right to sleep. I turned on my side to go to sleep, and faced Whitney. I lay there with my eyes closed, and I think that I fell asleep. I woke up and felt something, it was in my crotch area, my eyes had adjusted a bit and I could see that the covers had been pulled down off me, and Whitney was playing with my boner. I just lay there motionless, her cold hands felt amazing on my hot body.
I started to move my hips slightly so I was pushing through her hand, it felt wonderful. Within a couple of minutes I had an amazing orgasm. I think that I scared her when I was moaning. I didn't notice this, but she had taken her clothes off, and had her hand between her legs slowly circling her clit. I slowly took my hand and moved it over toward her pussy. I took her hand in mine, she froze, I slowly pushed it to the side and picked up where she left off, I could feel her wriggle as she held herself close to me. She was dripping wet, I was circling her clit. As she was approaching her orgasm, I knew this by her hip movement, I took my index finger, went inside her while I was still massaging her clit with my thumb.
Soon she closed her legs on my hand, grabbed me tightly, and came all over me. After she recovered herself, I looked over to her and told her that was amazing, she said the same, we held each other, our bodies pressed against each other, and all of our limbs intertwined, until about 4:00am, then she went back to her bed. I still have great memories of that experience. She moved away later that year, and I have not seen her since. I will never forget that night.
