I have always gotten on really well with my sis who is 14 now. When other guys in school were having dreadful fights with their younger sisters, me an Rachel were helping each other out and supporting each other when mom and dad were getting at us. Oh sure, we had the odd scrap, but it usually only lasted like 10 minutes, and always ended up with a hug.
Last summer the family took a small house by the ocean for the month of July. There was mom and dad, a couple friends of theirs, and me an Rachel in this three bedroomed house. Rachel and I agreed to share a room with two single beds quite close together. On the second night we were there, we were in bed. The rest of the house was asleep cos I could hear snoring.
With the lights out, the room was still quite bright, and I could hear movement in Rachels bed under the bed clothes. I guessed she was rubbing which made my cock hard, and I started to jack off too as quietly as I could. After a minute or two, Rachel said 'It feels nice doesn't it?'
I said 'yeah, it does'. Then after another minute or two she said
'Let's do it together'
I got out of bed, and got in beside her. She was naked, and I could just see her little mound with a small dusting of blonde hair on it, and her lovely 32B breasts in the half light.
The bed was narrow, so she put her leg across mine and started to rub again. I could hear the squelchy noises of her fingers in her wet pussy, and I rubbed my cock really hard.
After a minute she said 'Finish me off bro', and guided my hand to her gorgeous wet slippery vagina. I rubbed her clit round in a circle and in no time at all her back arched and she quivered to a nice climax. It lasted for a few minutes and she squeezed her legs tight against my hand.
After she had relaxed, she grabbed my cock and wanked me really firmly till I spurted all over her thighs and tummy,
It felt so good, and she seemed to really enjoy me cumming on her.
After she had cleaned up, we kissed for a while before falling asleep in each others arms.
We slept together all that month and many times since. She's soooo cute and really sexy
