I was over at my cousins one day. She was 15 and so was I. She was always asking me about my dick, pubic hair, erections, and masturbation. She told me "come up to my room". I knew this meant I was going to pull out my penis for her to see again. Sure enough, she locked the door and sat down and unbuttoned and unzipped my pants. Out came my already hard penis. She surprised me saying, now lay down on me and rub it on me. She had left her underwear on but pulled down her pants.
I kept rubbing it on her and she said, wait hell with it. She then pulled down her underwear exposing her little black bush. I was able to rub it. It was so wet, I was amazed. She said, "You can't put your dick around it now cuz that's how I can get pregnant". I realized it would be so wrong to get my cousin pregnant. She threw me a towel and said, "Do it". I had jacked off for her a couple of times so I knew I had the go ahead. It went very fast. She let me do that several other times and one time she actually had me stick it in.
We were always masturbating for each other. She did it for me about 15-25 times. One time, we were on a walk and she said, "Hey, hold on a couple of minutes". She dropped her pants, and layed down and masturbated. So, I pulled my dick out and did it too. It was just something we did. It was kinda cool.
She has since gotten married and we don't talk about it anymore. But she has changed in front of me and I got to see her new boobs. They were very nice.
