You'll probably find this really gross, but I'm afraid that's what I do and if you don't like, then I'll keep out your way.
Hi. I'm Jenny (fifteen years old in the UK), and all the fourteen years of her life, my sister has shared a bedroom with me. We've always been very close sisters, as kids we used to bathe together, and were inseparable. Most nights we sleep together in the same bed, although we have two in our room. Normally, we would just snuggle up - occasionally naked - and sleep, maybe with a little kiss first.
Last night, we had been flicking through FHM, I know it's for men and softcore, but it turned us on! Anyway, we went to bed as usual, and it was a litle hot so we undressed to our panties. We cuddled, but unusually for me (probably thanks to all the hot covergirls) I was absolutely tingling all over! Especially in my crotch, which was dampening! Well it was all so powerful and getitng to me, I just couldn't lie there and leave it like that. I needed to release all this pent-up excitement! So Sarah lying there beside me unintentionally added to my sheer horniness, and on the knifedge of sanity I rolled onto her thigh as if I was just cuddling her, and ground my pussy right up towards her pelvis. To my surprise, well I wasn't so surprised just it was unexpected, she was sopping wet too, and pushed herself up into my loins! That had to be my biggest turn on in - well, ages! So giggling we played at that for a while, and kissed. We'd never really gotten anywhere with anyone before, so what we did I'll call tonguing but it was probably nothing like that!
After about ten minutes, with our legs entwined, our miniscule boobs pressing, and really embracing tighly kissing away, we could feel ourselves on the verge of an orgasm! We're almost identical sexually, so we would no doubt go at the same time. This happened, and in absolute euphoria we almost passed out, sopping wet by very happy.
Looking back, I'm pretty shocked at exactly how far we went l;ast night - she is my sister! - but (u'll think I'm sick for this) I wouldn't hesitate to experience that again with her, my darling sister, my first love!
