The bedroom was briefly illuminated by a massive flash of lightning and a deep rumble of thunder that caused me to waken from my sleep. Reaching over for I hit my alarm clock to see the green clock face light up showing 1:30am, jeez I had fallen asleep again whilst studying for my final exams. Climbing off the crumpled duvet, scattered with my history books and coursework I walked to the wall and flicked the lights on. My room was half of the attic extension that had been recently finished in the summer, the other half was my baby sister Jana's, the two rooms met on a staircase off which we both shared a bathroom.
Stretching out the cramp in my back I walked over and watched the rain lash down outside the window and noticed that Jana's light was still on next door, maybe she was watching television or reading. I soon cleared the bed and stacked up my books and papers on the desk and walked out on to the landing and entered the bathroom and turned on the shower. Stepping out of my shorts and tee shirt I stepped under the hot stream of water and washed away the sleepy feeling that still hung over me.
Ten minutes later I emerged with a towel wrapped around my waist and headed back to my room, noticing the light still emanating from beneath Lana's door on the landing. As I put my hand on my door handle I stopped in my tracks as I heard a gentle moan come from my sister's door, I turned round and put my ear to her door on the other side of the landing. Listening carefully I was sure I could hear a muffled television and the unmistakable sounds of pleasure, my little sister was getting herself off!
Perhaps at this point I should describe my sister Jana, she is a year younger than me and turned eighteen a few months back. She has the sort of drop dead body that any normal man would love to explore, 5' 8" tall with long blonde hair that she often puts in to cute pigtails. Due to her long standing involvement with the college swim team, she is extremely toned with an arse to die for and firm, jutting breasts, trust me I have often watched her sunbathing during the summer with her friends in the garden. The way she fills a tiny white bikini is almost obscene with her generous breasts held in by such a flimsy outfit.
So the idea of my gorgeous sister getting off next door to me was certainly causing my heart to race and my cock to stiffen under the towel around my waist as I bent my ear to her door. If only I could see her in action with out her knowing? Squatting down I couldn't see under the door, and there was no key hole on the lock either. Frustrated I turned to go back in to my room and beat my cock in to submission when I remembered that there was a maintenance hatch in the bathroom that entered the dead space between the two rooms in the attic. I recalled seeing the builders running the electric cables through the gap when the extension was built, maybe it would provide a peephole?
With my cock firmly tenting out my towel I went back in to the bathroom and looked around. I opened the towel closet and sure enough there at the back was a small door about 4 feet high, with nervous fingers I tried the handle. It opened and from the light in the bathroom I could see a narrow corridor about three feet wide running between the two rooms, the walls of which were covered in cabling and pipes. I locked the bathroom door and stepped in to the narrow confines, the floor was covered in wood shaving and the smell of plaster hung heavy, but my iron hard cock and beating heart drove me onwards. Moving slowly as not to make a sound I edged along the corridor scanning the wall that made up Jana's bedroom wall for any beam of light and my cock lurched when I saw one. Silently I crept forward and put examined the hole, it appeared to be around a light fitting that had been put up similar to one in my room. I leant forward and placed my eye at the stream of light, inside all my dreams were answered.
Jana's bed is opposite the peephole and as I looked on I could see her laying on the bed before me dressed in a pair of lacy pale green panties and matching bra. She was cupping her swelling breasts together and gently teasing the very erect nipples that were poking through the thin material. As she pushed the fleshy mounds together her knees fell open and her panties were stretched by the motion. I glimpsed her mound through the material and a developing wet patch. My hand released the towel around my waist and I gripped my cock hard and started to slowly pump it as I watched my little sister get off.
Kneeling forward Jana reached round and released her bra, tossing it on to the floor beside her. With the bra gone I got my first good look at her firm breasts as she ran her hands over them and firmly rolled her nipples between her thumb and fingers, eliciting a groan of pleasure from her innocent mouth. Cupping her left breast in one hand Jana then snaked her other hand down to her soaked panties and rubbed her pussy though the material for a few moments before lying back and peeling them down. There only a few feet from me was my lil sister's pussy, smooth and hairless except for a tiny landing strip of wispy blonde hair above it.
