When I was 7 and she was 9, my stepsister used to experiment with me. It started with us kissing under the covers, and eventually she started to touch my nipples and my pussy over my clothes, and asking me to touch hers. She taught me how to kiss with tongue, and we would french each others necks and ears too. She coaxed me into taking my shirt off so we were both only in panties and we would french kiss while rubbing our nipples together. Eventually she taught me how to hump and we would rub our pussies against each other over our panties. I was only 7 when I licked my first pussy. I remember how she laid on our bed and spread her legs, encouraging me to kiss her down there. The taste was sour, but her moans were so sweet that I wanted to keep going. Then it was my turn, and I'll never forget the feeling of her sucking my bald little cunny like that. We then began tribbing. The first time I ever had an orgasm was with her, when we were camping in the backyard. It was just us and our parents were inside. We took off our skirts and panties and started to rub our wet pussies against each other. I was on top, tribbing my pussy against hers. I was so nervous but she kept begging me to go faster, harder while kissing her. She grabbed my hips and moved me against her. I ended up cumming and I was so confused on what was happening, I was a little bit scared but it felt so good. I found out later that her mom was watching us the whole time but she never said anything to anyone else. I wonder how wet she got watching me cum for the first time at 7 years old.
