I had a very 'close' relationship, and still have with my sister. I thought it was a bit wierd but reading the stories on Solo Touch I realise I am not alone in the world of horny young pre teens. On holiday when we were 13 and 14 we shared a room which had an adjoining wet room within the flat our parents had. After swimming each day we would both shower each other off still in our swim gear, my sister would hold the shower head and direct the jets against my cock watching it stiffen beneath my speedo's and after a while I would feel my cock twitch as a mini orgasm hit me, I would direct the jets over her developing nipples and between her legs, over her bum and her pussy watching it swell beneath the tight swimsuit fabric until I could see the ridges of her sex, as she came close to her cum she would hold my hand to direct the water jet, she would close her eyes, hold onto my shoulder and gently sway about until she jerked and went rigid, all of this made me stay stiff for ages.
Sometimes we would play fight afterwards and I would suddenly get an urge to hold her tightly as a strange but nice feeling shot through my cock which sometimes was pressing against her bum as we wrestled on the bed. We shared bunk beds, my sister on top and some mornings I would wake up with it moving, I would hear her gasping and knew she was masturbating, minutes later I would join her and squirt a wad of cum into my hands as I listened to her. At home I had spied on her wanking many times. If mum and dad went out my older sister would be in the bath, I would say I was going on the computer leaving my younger sister alone in the lounge watching TV. The minute she thought she was alone she would lie back on the sofa and put a cushion between her thighs and ride it, I would sneek a look through the glass door, stroking my dick as she rode the pillow, her nightie would ride up and I got full view of her hips rocking and grinding, she would speed up and slow down about three or four times until the last time she would get faster and faster until she jerked and went stiff, her thighs jerking around the pillow.
Another time she used the blanket from the sofa between her legs and one time I saw her sat on the floor against the sofa in her PJ's her legs were up and apart and she had one hand on the other rubbing herself through her PJ's, that night I went back to my room and then made it obvious I was coming into the lounge. She had stopped rubbing herself but was bright red, a few minutes later she jumped back up on the sofa and pulled a cushion over her tummy, out of the corner of my eye I could make out little movements beneath the cushion, I let my hard on poke up against my boxers as she rubbed away. One night I slept with her and spooned against her back with my hard on sitting in the crack of her bum, moments later I thrust against her and jizzed onto her pants-we had sexy fun growing up!
