I was twelve at the time and my friend was fifteen. We were having a sleepover once, and we got bored. So out of the blue she asked me if I had ever masturbated. I had no idea what it was so she said that she'd give me the night of my life.
I was a little nervous when she told me to take off all my clothes, (we were home alone). Then she told me to lay on top of the sleeping bag with my legs spread out. I was very surprised when all of a sudden she started to caress my boobs.
At first I didn't like it but soon it felt wonderful. She moved her hands down my body and rubbed the outer lips and then the vagina, then she massaged my clitoris. It felt amazing. Soon she took off her clothes and told me to do the same to her.
