I was then 13
Hannah was my best friend in high school she was quite shy and she had huge breasts which fascinated me and I wanted desperately to squidge them hard and rub them against my clit.
I'm not a lesbian but the thought of girls masturbating themselves and each other makes me so so horny and when I masturbate now, I think about girls wanking themselves in public places secretly.
Anyway, Hannah was for sure not a lesbian and was not interested in me, but I used to think about her touching her wet clit because I knew she must masturbate because most girls do. The thought of her orgasming secretly late at night when her parents were asleep or maybe even doing it under a blanket with people around made me so horny.
When we would do things like play on the trampoline I would try and rub up against her tits and I would touch her whenever I could. When we would sit cross legged on the trampoline I would want to slide my hand under her skirt between her lips and onto her clit and I imagined making her so horny and wet.
One night at a sleepover we had said our goodnights. She was in her bed and I was on the floor, I thought she was asleep and the thought of her so close to me made me so horny that I slid my hand into my knickers and fingered my clit fast. I rubbed it feeling dirty looking at the shape of her body under the covers.
I writhed about as I orgasmed, feeling my wetness on my fingers and stroking my wet slit and clit.
I rolled over to sleep and about five minutes later I heard a rhythmic noise and opened my eyes (it wasn't very dark in her room) I could see her duvet rising and falling with each wank of her pussy. I had my eyes half closed and was lying really still, I was feeling so sexual and aroused that I started playing with my clit again.
She pushed the covers off and I could see her hand rubbing her clit under her knickers. Her legs were straight out, spread and tensed up. Her hand was moving hard on her clit. She was pressing down hard and was rubbing fast. I was so horny and I was doing the same thing but more subtly so she wouldn't notice. I came hard before she did. She came shortly after and uttered a small gasp of absolute pleasure and I could see her wet pubic hair coming out the side of her knickers. I wanked over this memory plenty of times since.
