I guess I should start out by mentioning that everything I write on this site, including this story, is 100% true!
My best friend and I met in sixth grade, and that year started what would be a long tradition of sexual experimentation with each other.
I remember the first sexual thing we did together. We were both in a tent I had set up in my back yard, and took our shirts off and looked at each other's breasts. We would stand on our knees and smoosh our boobs against one another's, and say, 'They unite!'
That same year in sixth grade, we were in her basement where she had a blue overstuffed beanbag chair. She told me how she liked to straddle it and hump it, and dared me to do the same. So, I did! Secretly I thought it was the sexiest thing ever, and made me so incredibly horny to be masturbating in front of her. At first I had on all my clothes, but she dared me to take off my pants, and then my underwear. She said the more I took off, the more she would dance sexily for me as I was masturbating, which she did. There I was, my panties around my ankles, furiously humping this bean bag chair. I was really getting into it and had a hard time focusing on her dancing, and wanted her to watch me and my pussy thumping against the chair.
Next it was her turn. She did the same, where she started fully clothed, and gradually took off more and more until her panties were down and her ass was wiggling around in the air, humping the chair. I was dancing for her and trying to watch at the same time.
My best friend and I would have many more sexual adventures together, which hopefully I'll post here! I hope this story made you horny if you happen to be masturbating right now, like I'm about to. My pussy got really wet remembering what happened and typing it out! Enjoy, and happy clit rubbing!
