My beautiful sexy sister Bernadette was 12 and I was 11 the first time we touched each others tiny pussy's. We lived on a small holding with our parents and our older brother. We were pretty isolated from school friends after school and weekends because of distance so my sister became my best friend and I hers. Bernadette was totally different to me in coular and looks and most people never took us for sisters. Where I was blond she was brunette, she had brown eyes mine were green. Bernadette had lovely natural tanned olive skin and I was pale! When we changed she would often tease me about my white behind and I would act hurt so she would have to say sorry and hug me. Bernadette & I would often play fight with our brother and it was after one of these play fights that we touched each other. Bernadette & I always bathed together and it was a great time to play and laugh and talk about the day while washing each others hair and back. Our mom would often sit with us for a while but would then leave to give us a bit of space. Bernadette and I would always compare our boobies or lack therof! Again we were different, her nipples were brown where mine were pink. She had started to bud and I would pinch,pull or squeeze her nipples when she asked me or I would just watch her as she showed me what she liked doing when she played with herself on her own. My chest was flat but Bernadette would take her finger and push my little nipple back against my chest that would make me feel yummy! Bernadette asked me while we were unchanging getting ready to bath if I felt strange or excited in my stomache when I would get pinned by my brother when we had our play fights ? I lied and replied no but I said I did feel his penis was hard sometimes. Bernadette said she had that day and although it felt good she was also a little scared to feel that way because he was our brother. We were both standing bare looking at each other when Bernadette came closer and took my finger and put it inside her while she looked at me. She was wet and she moved my finger inside of her and lightly closed her eyes and told me it was not the first time she had felt this way. She told me as she moved my finger in her pussy that she first started getting "butterflies"in her pussy when I would wash her back. I took my finger out of Bernadette's tiny pussy and asked her why she had never told me she felt that way. She said she did not want to scare me or upset me. I could see she wanted to cry and told her not to as I had lied and put my finger back in her pussy to show her it was ok. We were quite and did not speak as she played with my finger in her pussy until she asked me to lock our door and to please use 2 fingers if I could get them in her pussy. As Bernadette laid on her bed I entered 1 finger and tried a second 1 but she was to tight and I could see I hurt her when I tried. I told her she was tight like me and she then took my second finger and asked me to rub her clit. I could see and feel my sister was getting more excited and for the first time in my young life I felt super horny and my own little pussy was getting much wetter because of been with someone else and not just in my dreams. I would stop rubbing the clit of Bernadette every now and then to rub my own or quickly finger my wet pussy and after a while Bernadette said I should not stop and adjusted herself to play with my pussy as I was doing hers. Bernadette had a bald pussy like mine except I could see a few small dark hairs and the inside of her pussy was more red where mine was pink. As I parted her thin pussy lips to look and rub her clit I could tell she was bigger than me. Without warning Bernadette tightly crossed her legs round my fingers , started shaking and let out a loud sigh and said softly in my neck my God dont stop! Bernadette was still shaking when she started to cry and uncross her still shaky legs and release my trapped fingers. As Bernadette laid back on her bed I could see how wet she was and as I looked at my wet fingers I decided to taste her and started sucking my finger. Bernadette opened her eyes to see me doing this and inserted her finger in my pussy and then offered it to me to taste. I tasted myself and thought we both tasted of the same sweet innocent taste.
