When I was 13 I went to an all girls boarding school and I can tell you there was a lot of sexual experimentation that happened there. We were all horny little bitches with raging hormones. I was in a room with 4 other girls and every night we would be doing sexual things with each other.
All of us had done kids stuff previously like comparing our vaginas and some touching but school was a whole new level. We were always touching and fingering each other. Constantly comparing our boobs and playing with them and spent many happy nights fingering and watching each other masturbate.
Anyway one day a new girl started at our school and she was assigned the vacant bed in our room. Her name was Olivia. She was shy and quiet but that wasn’t gonna be the case for long. We figured to make her first night memorable. So we all got ready for bed. She was really shy about getting undressed in front of us and was trying to be discreet. Meanwhile we were all just getting undressed with no hesitation. Me and this girl Tori began fondling each others boobs. Tori was making moaning sounds so I slipped my hand between her legs and rubbed her pussy. Another girl Jasmine came over by us and began to play with me. I was loving it. So now the three of us are just standing there fingering each other, I can see Olivia pretending not to watch was she couldn’t help herself. I whispered “It’s ok we all do it. You can watch. “ She was really watching everything we were doing. Tori asked her if she played with herself. She was so embarrassed but said that she did. Tori asks her if she ever did stuff with another girl. She said no except she had played with her neighbor when she was about 7 or 8. So Tori goes “well now you’re with us and you can be part of our group”. Olivia was standing beside us so Tori looks at me and says “lets show her what we do.” I nod and we push Olivia onto the bed pulling off her pajamas. She is quietly protesting but we carried on. I began to massage her boobs which were not very big while Tori fingered her. She wasn’t protesting any more. She relaxed and me and Tori took turns to lick her out. She was loving every second. She came several times and kept saying “stop I can’t take it” but we kept on, I was fingering her pussy so fast and she was soaking wet. Finally she came one more time. Her body was shaking and you could see how wet her pussy lips were. That made Tori and I so horny that we got in a 69 and licked each other out. As we were doing it I saw Olivia watching us and rubbing her pussy. Jasmine got together with the other two girls and fingered each other. After Tori and I both orgasmed, we lay together and kissed. It was pretty late by now so we figured we should go to sleep. Anyway that’s was Olivias first time with us. She became more horny than us and soon was the one who would start everything.
Over the rest of that year there was a lot of sex, licking, scissoring and fingering. I still think back to this day when I masturbate now.
