Reply: Do other tween girls experiment at sleepovers?

For sure they do and not just at sleepovers. Me and my friends would go to one of our houses after school (usually whoever had parents that were at work) and get naked and finger each other. We were 10 years old when it started and continued till we were about 14. From these experiences we all learned how to pleasure ourselves and have the best orgasms from masturbating and oral. When one of the girls realized that the electric toothbrush could bring enormous pleasure on the clit, we all had to get one hahaha

We didn't have sleepovers when we were young, it was a custom in my country.  But we did go on retreats with our school, all girls and nuns. I was fourteen when a nun helped me with my bra, cupping my new breasts, and pinching my nipples. She kissed the back of my neck, and told me how pretty I was. She reached around and put her hand in my crotch, feeling me, poking me.  Telling me I was so pretty and one day I was going to be a woman and she wanted me to remember her. She kissed me on the mouth and put her hand in my pants.  She sat on the bed, and opened her legs and pulled up her gown and she was without panties.  I didn't want to kiss her but I didn't want to go to hell for disobeying a nun.  I kissed my first girl, between the legs, and licked her. I could not stop.

Maybe that's why I became a lesbian. 

When I was 9 me and my friend next door (also 9) did a lot of masturbating together. One day we were comparing our vaginas and started playing with ourselves which quickly progressed to fingering each other.
So around the time we were 10, we both went to another girls birthday sleepover and late at night when we were all in pajamas and her parents had gone to bed, we all stripped off and compared our privates, then masturbated as we watched each other and very quickly progressed to fingering each other. After a while two of the girls got in a 69 and licked each other and then we took turns. It was really good.
From that night on every sleepover became a night of sex fun and exploration.
So yes, definitely tweens girls experiment.

That's a definite yes!!!
Me and my friends often compared our private parts from about age 6, maybe 7. When I was 12 I went to a girls birthday sleepover and the main objective of the birthday girl was to finger every one of us and have us finger her. We began by comparing our boobs and vaginas and then the touching, fingering and rubbing began. One girl who was a year older and a bit more experienced got us to lick each other. A whole bunch of very horny girls together was quite a night.
After that, it was something we did at every sleepover or even after school some days. We'd meet at whichever girl had an empty house with parents at work and get undressed and do stuff together including fingering, licking and scissoring. By the time we got into boys we really knew how to pleasure ourselves and each other.

OMG yes. In my case it started when I was 9 with my best friend Alexis at a sleepover. We were always fingering each other. Then when we were both 11 we were at a birthday weekend sleepover and late at night when the parents had gone to bed, we all stripped off and fingered ourselves and ultimately each other. Then at most sleepovers or even some random afternoons when hanging out we would do a lot of comparing of our vaginas and fingering. It didn't;t stop till we were all around 14 and hung out with boys. Having said that me and Alexis still masturbated each other when we were 16.

We did it all the time. First time was when we were all 11 years old. It began at a sleepover when it was late and the girls parents had gone to bed. Here name was Lucy and her room was at the other end of the house. She suggested we all compare our vaginas which went on to us touching ourselves as we all watched each other. Then we began touching each other and there are a lot of wet pussys that night.
Next sleepover at Lucy’s house there were 7 of us. We did a lot of sex that night including some licking and a lot of fingering!!!! Actually it happened every time we had sleepovers till we were about 15.
