Susie was 19 years old, and worked at our local post office. Dad was employed by a well known insurance company, and worked in one of their London offices. My Mum had some kind of desk job at the local council offices. Both Mum and Dad worked the usual 40-hour, 5-day-week, but Dad in particular, spent a good part of his day commuting. Susie would have been about 5' 5'' tall, and I guess about 140 lbs in weight. She had naturally dark brown, shoulder-length hair... blue eyes, and very pale skin. Even then her breasts were quite large, with prominent nipples. She had the most gorgeous bum, and very nice legs. Her pussy mound was quite prominent, with just a very small amount of pubic hair at the top, which she always kept very well trimmed. Her pussy lips were smooth and colored light pink. To be honest with you, I thought that my sister was the most beautiful woman on earth. But then I guess I was biased. When it came to clothes, Susie was very "Girlish," preferring dresses to jeans... especially during the summer months, when she used to take great pleasure, much to my delight, in wearing very low cut dresses, that did nothing to hide the curves of her breasts. The dresses were often only mini-length, which afforded a great view of her bare legs. She would wear as little as possible around the house, especially when our parents weren't around. More often than not she would prance around in just a bathrobe, and sometimes in just her bra and panties. Mum was forever telling her off for behaving like "some kind of cheap slut!" I was about an inch taller than Susie, and perhaps a little slimmer. I didn't consider my appearance anything out of the ordinary. In fact I was quite plain. I had the same coloured, shoulder-length hair, and also blue eyes. My cock wasn't much to write home about... maybe about 6" long when fully erect... but it was quite thick (at least, that's what Susie said). I was usually in jeans and tee shirt. Or, if the weather was really hot, then I'd be in my shorts. I had been fantasising about my sister for a few years... in fact, ever since I'd discovered the joys of masturbation. I'd had many a wank, just trying to imagine what Susie looked like naked. Were her tits as big as they looked? Was her bum really as juicy as I had imagined? Unlike a lot of my school friends and playmates, I was quite naive. The only sexual experiences I had enjoyed until then was when a new family moved in next door. They had a little girl named Molly. We were both about 9-years-old at the time. Just like us, they had an old shed at the bottom of their garden, where Molly and I played games like "Doctors and Nurses." More often than not the game would end with my hand inside her little navy blue panties, and my finger inside her damp little slit, as she playfully squeezed and rubbed my little cock, watching in total fascination, as it twitched and hardened. I still remember her frightened little giggle when she saw me cum for the first time. She wasn't the only one who was scared right then. It was the first time I had ever cum, and it scared the shit out of me. Those little games lasted for quite a while, and we became quite expert at masturbation. One hot and sunny day, near the end of July, I was on school summer holiday. Susie had just started a two-week break from her job. I guess it must have been about 11 AM. Mum and Dad were at work, and I thought that my sister had gone out, because I hadn't seen or heard anything of her. I was inside our shed, deeply engrossed in one of my Dad's well-worn porno magazines which he kept hidden (or so he thought) in an old chest. I had been wanking furiously for some time when I sensed that I was being watched. I glanced sideways and had the shock of my life. My sister's face was pressed against the window. I started to panic, trying to hide my cock from my sister's gaze, but I knew that it was too late. She shouted for me to let her in. All I could do was to stand there, with my head hung low, my shorts halfway down my legs, and my cock standing upright, swollen and rigid, as Susie read me the "riot act." She called me a "dirty little bugger." She said that I should be "ashamed of myself," and that "I should find something better to do... like homework for example!" I burst into tears and kept saying how sorry I was. I begged her not to tell anybody... not a soul. I told her that I would do anything she wanted... anything at all. I must have spent a good ten minutes, "signing" my life away. Of course, I was too young, and far too thickheaded, to realise that she was enjoying every minute of my torture and humiliation. The cruel bitch just stood there with her arms folded, and let me go on, and on! Susie eventually forgave me, promised not to tell anybody what she had just witnessed, and to my astonishment, openly encouraged me to finish my wank right in front of her... there and then. That progressed to watching each other masturbate, then doing it to each other... me finger-fucking her pussy while she rubbed my cock. Almost every chance we had to have sex, we took... eventually including full-on fucking! Regardless of the consequences and the risks of getting caught; we had sex in our bedrooms, the bathroom, the kitchen, and even the garden shed. Those few weeks were like one long orgy. Susie loved to have me watch her fuck herself with all kinds of different objects, such as fruit, vegetables, candles, and a hairbrush handle, while I stood in front of her, tugging at my cock for all I was worth, and mouthing the "dirty" words that I knew she loved to hear. We had been having sex, at times often, and in places where we ran the risk of getting caught. Susie claimed that the risks made it all the more enjoyable. I had to agree with her on that score! On several occasions, my sister had mentioned that she'd like us to do something really outrageously risky one day, and promised me a big surprise! One night, Susie and I were in the lounge with Mum and Dad, watching "News at Ten." My sister was wearing her usual bathrobe, and I was in pajamas and a dressing gown. Mum and Dad had the armchairs, while Susie and I shared the couch. When the advert break started, our parents departed to the kitchen to make their bedtime chocolate drinks. Susie didn't share their taste in nightcaps, and had just downed her third vodka and orange. "I've got a treat for you little brother," she said, as she stroked the top of my leg. I asked her what she had planned, but she told me that I'd just have to be patient, and I'd soon find out. Mum and Dad returned with their drinks and stayed with us until the news ended. Then they said goodnight, and went up to bed. About 15 minutes had elapsed, when my sister told me to go to the foot of the stairs, and check to ensure that all was quiet. I told my sister that there wasn't a sound from our parent's bedroom. She told me to wait where I was, give her a few minutes, and then join her in the kitchen. Five minutes later I walked into the kitchen and had the shock of my life. I was greeted with the sight of Susie draped backward across the kitchen table. Her bathrobe was wide open, pulled up to her waist. Other than that, she was totally naked. Needless to say I achieved an instant hard-on! She had her legs wide apart, and in her hand was a fairly large cucumber. "Bloody hell, sis!" I said, staring first at her large breasts, then her pussy. "What do you think you're doing?" "This is the surprise I promised you, little bro," she replied. "You're going to fuck your big sister with this." She handed me the cucumber. "But I can't sis. What about Mum and Dad?" I was shaking by then, both with fear, and an awful lot of excitement. "What if they come down?" Susie assured me that they wouldn't. Still shaking, I placed the tip of the cucumber at the opening of my sister's pussy... and pushed. "Ouch! Steady!" she yelled, almost loud enough to wake the street... never mind our parents! "Wet it or something, and try to be a bit gentler. Spit on it, and try again." I obeyed her instructions and tried again. That time I made a bit of progress. I actually managed to push about an inch of the cold, green thing inside her tight pussy. "Oh fuck me, Bri... fuck me... fuck your sister's tight cunt." Once my sister starts to talk "dirty," it's a sure sign that there's no turning back. By then I was almost as breathless as Susie. No matter how hard I pushed, I still had managed no more than an inch and a half. She told me that we needed lubricant, but the one place you're hardly likely to find KY jelly is in the kitchen! She told me to look in the kitchen cupboards for a substitute. "Will this do sis?" I asked, holding up a bottle of olive oil. I studied the label, and joked sarcastically. "I don't think this'll be any good sis... it says 'Virgin' on it." "Oh very fucking funny!" she snarled, obviously not appreciating the joke. "Just put some on, and fuck me. I want it right up my fucking cunt... and I want to watch you rubbing your prick while you do it!" I poured some oil onto the cucumber, and dribbled a few drops into her pussy hole for good measure. Although very slippery, I managed to insert it again, and started to push. Much to the delight of both Susie and me, the cucumber slid gently, deeper, and deeper into her hole. Susie had managed to take a good five inches, maybe more, and her oily pussy lips were stretched to the limit. I began to pump it in and out with one hand, while rubbing my ever-hardening dick with the other. "Oh for Christ's sake! Fuck me!... Fuck my tight little cunt with that thing!" Susie was in a trance-like state by then, and there was no way that she would allow me to stop. "Fuck me bro! Fuck me hard! Make me cum!" I was pumping as hard as my little hands would allow, then suddenly she came. I managed to catch the slippery green giant before it hit the floor, and watched as Susie finished herself off with her fingers. My big disappointment was the fact that I still sported my erection after all that excitement. We managed to get ourselves, and the kitchen back to some sort of order, before making our way upstairs. Susie no doubt to slept soundly. I masturbated, as I usually did before nodding off. (Well, it beats reading!) Everything was the norm, as the four of us sat down to breakfast on the morning after. That is until Mum announced that we'd be having a salad for lunch... a cucumber salad! Susie and I just looked sheepishly at each other, and returned to our corn flakes. I think I've made it pretty clear that I was very naive at this point in my life when it came to sex, but I was desperate to please Susie, and desperate to fuck her... fuck her for real. I wanted her to show me how to do it, in the same wonderful way that she'd taught me to masturbate her, and pleasure her with all those exciting objects. Objects like that cucumber. I wanted to know just how it felt to have my cock inside her pussy. Her pussy that had felt so hot and wet when I'd fucked her with my fingers. Thankfully I didn't have to wait too long. A few days after the cucumber episode, and just after Mum and Dad had left for work, I heard my sister call me from her bedroom. Wearing just my dressing gown, and having only just gotten out of bed, I walked into her room. She was lying on top of her bedcovers... completely naked, with her legs spread wide, and gently stroking her pussy. Although I'd seen my Sister naked many times, I had never felt quite so excited as I did at that moment. She beckoned me to the side of the bed. "You love watching me do this, don't you? You love watching me play with my cunt," she said, as she pulled her pussy lips wide open. Then she went on to say, "I feel as horny as hell, little bro, and I think it's about time I showed you how to fuck!" I couldn't believe my luck, and I can't tell you how excited I was. She told me to remove my dressing gown. I did. My cock stood bolt upright and rock hard. I followed her instructions and positioned myself between her legs, waiting for her to make the next move. "Fuck me little bro," she whispered. "I want to feel that big hard cock of yours inside my cunt." I was reasonably sure I knew what to do, because I had seen enough pictures of men fucking women in all those magazines that I had read. I knew exactly where to put my cock... but sadly I couldn't do it! It was a major disaster. A total, major, embarrassing disaster! To say that Susie was angry, is putting it mildly. She called me "a total waste of time," and told me to "Fuck off!" The second time was much better, although short lived. Susie walked in on me one day as I was about to take a bath. She was wearing just a dressing gown. It was open. We tried to fuck standing up, but eventually ended up on the floor. That time I actually managed to insert my cock into the appropriate opening, and everything was going well... that is until we heard the doorbell ring. That ended that session! Thankfully our third attempt was perfect. I awoke in the early hours to find my sister standing beside my bed. She was completely naked. It was a hot and clammy night, and I had only a sheet covering me. She told me that she couldn't sleep, and asked if she could join me. I hadn't been able to sleep either, and was sporting a huge hard-on, brought about by thinking of her as I often did. She threw off the sheet and joined me. Within seconds our warm and humid bodies were pressed against each other. Her large breasts were squashed against my chest, and the head of my prick (which was swollen and throbbing) was hard against her very damp and hot pussy. We lay like that for several minutes, with the only sounds being that of our heavy breathing, and the noise of my Dad's snoring on the other side of the wall. Susie was first to speak. "Bri...?" "What is it sis?" "Fuck me!" she whispered. She rolled onto her back, and opened her legs so that I could lay between them. "Fuck me, little bro. I want to feel your big cock inside my cunt" It must have been 'third time lucky,' because that time everything went perfectly. At last, her 'little brother's big cock' slid slowly and gently into her 'hot, tight cunt.' Half an hour, and several positions later, we lay in each other's arms, totally exhausted, and totally spent. I think Susie came about 6 or 7 times while we were connected. I managed to pull my cock out of her pussy at the very last moment, before coating her with my cum. Looking back on it (as I often do), I would say that I had just experienced the most wonderful sexual feeling in the whole of my life. Even now, all these years later, I masturbate often, as I think of my cock buried deep inside my sister's hot, tight, and very wet pussy. I can feel it sucking me in, deeper and deeper up into her throbbing hole. As I think about it, I want to fuck her again. Brian
