Claire is my little sister, when she was 16 she could pass easily for 18 or 19, which came in very handy for her when she wanted to go clubbing too. I was nevery particularly close to Claire, she had her friends and I had mine, never the two shall meet according to Claires rules. I had hoped to myself that once Claire was older her friends would become a new source of girls for me to attempt. I already knew a few of them and they were gonna drive a lot of guys crazy though the years. Claire was turning into quite the looker too, she had shoulder length blonde hair, big bright eyes and a nervous smile. She used to carry a little weight but in the last year she had gained a few inches in height and the weight just left her, all apart from her chest which was quite a sight on such a slim girl. I was never good at judging bra sizes so i’ll admit to looking at her laundry to find out how big they were, 30 c.
When Claire started to go out the night bus I wasn’t too happy, not because of the protective thing but because she made me feel more self-concious than ever when I was talking to girls on the bus. I could hear he little gang of girls giggling when I got near them so I always made a point to get right near the back and leave them at the front. This seat choice also gave me a bit more privacy to enjoy a few drinks on the journey. While the boys got drunk in one crowd the girls did their thing in their crowd. This seating arrangement was very different on the way home, the bus was always more packed with people heading back for house parties and random one nighters who got hooked up in a club.
It was late summer and after a barbecue and a few drinks with my mates I was ready for the night out of town. As time went on my mates headed their separate ways to get cleaned up for the night I headed home for a shower and a change of clothes myself. Mum and dad were apparently out for the night, this became obvious as soon as I stepped into the house and caught the smell of cigarette smoke and the sound of Claire and her friends laughter. I ran straight up to my room before anyone saw me, not planning to hang around too long. From my window I could see Claire and three friends anjoying a few alco-pops, far too sweet for my taste but girls seemed to like them. Catherine, one of the more cute girls was sunning herself on a recliner I was sure I could see up her skirt. I couldn’t help but rub my cock a little through my trousers. God I needed some action tonight.
On the bus I headed toward the back with my mates to view everyone getting on while enjoying a few beers. It was like a cat-walk show down the isle of the bus. I loved the summer, short skirts and tanned legs were everywhere. This show was going well until Claire walked in, I had never seen such a miniskirt on her. If you were two steps behind her on the stairs you would see everything. My mates instantly notice this too and I got so many nudges I thought I was surrounded. Claire took a window seat near the front and the show contined with the next arrivals on the bus. The only problem now was that my mates kept comparing the skirt length to Claires, which I was mentally doing myself anyway. When we hit the town everyone split up to different bars, this was the normal routine because no doormen at the clubs wanted a large gang of mates arriving together. I never saw Claire again that night until the bus was due for us home.
My night was alright, I think the drink at the barbecue during the day added to me being more drunk than I liked to be and although I got talking to a few girls I got no action. Now I was standing outside waiting for the bus while my mates were either with girls of away for food. I saw Claire coming along the path with Catherine and some guy between them linking arms. It was only when they got near me that I realise the guy was with Catherine and Claire was alone. She looked around for someone she knew but in the end she must of seen no-one else and came over to me leaving Catherine to her man. “I take it your night wasn’t great for finding a guy” I said to her jokingly. “I got loads of guys coming on to me but all creeps” was all Claire would say before sitting on the wall beside me.
The bus was it’s usual packed self. My seat was still free because I left a few cans in a bag on it, people recognised this as ‘seat taken’ so I often bought a couple extra cans just to do it. I sat down and had expected claire to go back with her mates but she sat beside me still wrapped in my jacket looking a little worse for wear. “you don’t have to sit here, I’ll get my jacket later” I said. “i’m ok, all the girls are with someone so i’ll stay here” was all Claire mumbled back. As the crowd packed on it was obvious that some people wouldn’t be sitting and everyone shuffled towards the back. As Claire only really took up half a seat some guy sat down on the edge of it with his back to us. He was talking to the guys opposite and seemed to hardly notice, or care that Claire was behind him. As the bus moved off the guy leaned back and squashed Claire even more. Without a word she thumped his back, “piss off creep” she warned but a mumbled apology and no more room was all she got. “Do you mind if I jump up on your lap?, this guy is squashing me here and he stinks” Claire raised herself up and onto my lap with a quiet thanks before I ever had a chance to respond anyway.
Within ten minutes of the journey most of the people were either sleeping or making out. The lights were always turned off so that passing motorists didn’t see the drinking or the behaviour that was going on in the bus. Claire had her head on my shoulder and her back to my chest. She seemed fast asleep. She had moved her legs to the only comfortable position she could find which was one leg between mine and the other to the window side. This gave her leg room but I had nowhere to put my hands but in front of Claire and all I could feel was bare leg. The guy beside us still had is back to us and was snoring and nobody else could see so I was ok to leave my hands on Claires upper legs. I had started to doze off and in my drunken state I had started sliding my had on Claires leg. I only really realised when she moved slightly and the startled me awake again. My right hand was resting on the inside pf Claires leg and my thumb could feel her pantie covered pussy. I wasn’t really thinking, I was horny and my hand just repeated what it had done before when it was in this position with other girls. I squeezed her thigh before i slid my hand slowly further up until I was cupping her pussy. My middle finger laying along the fold of her lips.
Claire moved again, this time it was to arch her back and move her ass back into me more. I felt my rock hard cock resting between her cheeks. I started to rub her pussy again, my eyes were closed and instinct was driving me on. My index finger found the edge of her panties and I pulled them to the side to reveal a smooth wet pussy. Claire must wax or shave because there was not one hair there, just smooth folts of hotness. My finger instantly found the wetness and her clit, I used the wetness and rolled my finger along her lips. My thumb was on her clit and my finger was probing, looking for the hole. It pushed inside, just a little before I suddenly felt Claires hand on mine. I froze as she pulled my hand away. I was in panic, what was I doing?. Claire lifted her leg from the window side and brought it between my legs to join her other. I was waiting for her to speak but nothing. She raised her ass off me a little and I seen her hands go under her skirt to adjust her underwear. She sat back down and it was only when she leaned forward that I realised she was sliding off her panties. My cock instantly became rock hard again. She raised herself and moved her leg over mine towards the window again. It was then that I felt her hand touching my trousers from between her legs. Her fingers found my zip and it was down and her hand probing inside within seconds. My cock was its full 7″ and she pulled it through the gap in my boxers to stand full erect out of my zipper. My mind was racing along with my heart as Claire sat back on me. My cock was erect in front of my sisters open pussy and she was massaging the head like a pro. I placed my hands in the inside of either thigh as Claire leaned her head back, her hand continuously stroking my cock, “God I’m so horny Adam” she whispered. Who the hell is Adam was my 1st thought before all thoughts disappeared. Claire leaned forward and raised her ass again never letting go of my cock. I felt the warmth and wetness on my head for only a second before the tightness swallowed my whole cock. My cock was now fully inserted in my 16 year old sister.
Claire slowly started rolling her bum as my rock hard cock pumped ever so gently into her, she leaned forward and I felt deeper inside her, a quiet but definate moan escaped her. My mind was only focused on my cock and the desire to cum hard in whatever hole it was in.
