There's a little appetiser scene in it, but the seriously dirty incest is going to come later. If you enjoy it, please hit those stars at the bottom. P.S. I'm looking for an experienced editor. Chapter 1 Being somewhat shy and intellectual, few would suspect something like this from me. Fewer still would suspect the basis that it has in truth. * It was a scorching summer's day, just like so many others in the long holidays. Libby and I had been lazing about the house, just enjoying the air-conditioning, our parents being at work, and the promise of more holidays to come. Having just finished high school, my sister was a little nervous about moving up into the university world next year. I was three years older than her at 21, about to enter my final year. Poring over the map on the table, she said "Campus is so huge, how do you know where to go?" "You'll get used to it pretty quickly. Just follow your friends." I spoke reassuringly. She didn't look very convinced though, picking at the last of her salad delicately and brushing a wisp of her long chestnut hair behind her ear. "Okay. But what if I don't fit in?" She glanced at me shyly, then looked down again. Looking her over surreptitiously while her eyes were averted, I knew she had nothing to worry about. "Libby, you're a hot fresher. You'll fit in fine." I was pleased to see her blush prettily. "Just watch out for all the older guys coming onto you." I continued, only half-joking, and knowing this would embarrass her. My sister is pretty shy, especially around guys because she went to an all-girls school. I just prayed that she wouldn't fall for some college pussy-hunting douche in her freshman year. The very thought turned my stomach. Picking up her empty plate, she walked over to the kitchen. My eyes followed her bare legs until she disappeared around the corner. Short-shorts were in fashion that summer, and I was getting treated to acres of smooth flesh on a daily basis. Daisy dukes with upturned edges seemed to say: These tiny shorts aren't small enough for me. I wanna show you even more. Of course, I knew that Libby was no slut and just dressed to be fashionable, but it was doing my head in. Bloody Chloe! It was all her fault, seeing as how she had bought Libby those shorts in the first place. My sister was usually more conservative in her dress, but Chloe had bought her heaps of new clothes for her eighteenth, and most of them were far more daring than anything she usually wore. "You've gotta look good for the start of uni," the redhead had explained. Libby couldn't refuse the gifts from her best-friend-forever, and I think she was beginning to adjust to showing more skin. "Matt?" Libby had poked her head around the corner, apparently to ask me something. "Sorry, what did you say?" I apologized, devoutly grateful that she was unable to perceive the source of my distraction. "Do you want a popsicle?" "O sure, thanks." She returned in a minute, and I took the proffered ice lolly, glad to have something cold given the current weather. Chomping it down in a few bites and only just managing to avoid a brain-freeze, I watched her suckle hers gently. She looked so incredibly good, sucking away diligently, every so often lifting off to lick her lips. Maybe it was my overactive imagination, and it was a hot day, but she seemed to be enjoying it a little too much, sliding the tip in a bit deeper than necessary. I wondered if she had ever... Suddenly I realized that I was staring, and she was looking at me questioningly with raised eyebrows. "You've, um, got something there." I said, indicating the side of her mouth to cover my lapse in attention. "Oh." She said, brushing the sweet droplet away, looking a bit embarrassed. * It seemed pretty pathetic to be stealing glances at my little sister's body every chance I got, but in my defense she had developed pretty spectacularly over the past year. I'd always known she was cute -- beautiful even -- in a little-sister kind of way. But there was no denying it anymore; with rosy lips, perky tits, and a curvaceous ass, she was a total knockout. Compounding the problem was my lack of a girlfriend. Shyness runs in our family, and in many ways I had it worse than Libby. I wasn't hideous looking; I'd seen plenty of uglier guys with girlfriends. I wasn't broke either; in a year I'd be a college graduate with good job prospects. I wasn't even isolated; there were plenty of girls in my class. The trouble was that I got quiet around new girls I was attracted to. Some of them made an effort to get to know me, but I quickly entered the friend zone once they took my cool reserve for a lack of interest. Porn kept me sane. That and my right hand. I slept late into the mornings when I didn't have work, and spent long nights jacking off to whatever pretty thing took my fancy. Of late I'd noticed a disturbing trend for me to search for slender brunettes with big hazel eyes. On some level I knew that my narrowing tastes reflected a need to vent the sexual frustration building towards my sister. But I shrugged off this warning as a passing phase, trusting that I'd soon be enjoying my regular varied pornographic diet again soon. Having Libby living in close proximity but forever off-limits would be enough to scramble any guy's circuits. * She went out that afternoon as she often did in the holidays. She had a tight group of girlfriends who liked to go shopping, to the movies, parties; the usual. Not that she was a wild party animal or anything, but that year all her friends were turning eighteen, so there had been more parties lately. Her own eighteenth earlier in the year had been a small but pleasant affair at a fancy restaurant in the city. For my part, I spent the time facebooking intermittently and catching up on a novel I'd been meaning to read for ages, but hadn't got around to during the busy semester. On impulse I navigated to my sister's facebook page. With hindsight it's easy to see how far gone I was, how obsessed with her I'd become, but at the time it didn't seem that weird. Her profile picture showed her arm in arm with her best-friend-forever Chloe, both of them flushed with happiness. My eyes wandered appreciatively over Chloe's fine features, fair skin, and lush red hair leading down to her gorgeous full tits encased in a tight tube top. I took the link to Chloe's page and began leisurely scrolling through her photo albums. She had been the subject of many a fantasy, I had to admit, as she had been frequently coming over to our house to hang out with my sis for years. Before long, I came across a new set of photos she had uploaded recently and my eyes nearly popped out of my head. She and Libby had gone to the beach a couple of weeks back, and I could see that these photos belonged to that day. Chloe was radiant in her emerald-green bikini, which, whilst matching her eyes, was struggling to contain her breasts. The next frame stopped my heart; my sister looked good enough to kill. Walking side-on to the beach, her long, smooth chestnut hair shone in the summer sun, blown back by the breeze. Firm breasts stood to attention, perked up by the coolness of the recently-departed water. And stretched over her ass was a tiny black bikini bottom. I didn't even know she owned a bikini like that. Must've been Chloe's doing; bless her. Something snapped inside me. There and then I vowed to find that scrap of material. Owing to my throbbing cock, I got up and walked a little uncomfortably into her room. As quickly as I could, without leaving behind obvious signs of my intrusion, I searched her wardrobe shelves. Finding nothing, and with no small amount of trepidation, I riffled through the clothes in her chest of drawers. Just when I was despairing at finding my ticket to a massive cum, I struck gold, right at the very bottom of the lowest drawer. Obviously, she didn't want mom stumbling upon this. The bikini bottom barely weighed more than a tissue, but that scrap of stretchy material held together by string-fine cords was heavy in my hands as I carried it back to my desk. I maximized the picture of my sister, ogling her long tanned legs running up to that fantastic ass. I moaned loudly in relief as I freed my cock from the prison of my boxers, sooo thankful that my parents were at work, and only half glad that my sister was out too. I briefly reflected that having her in the house while I did this would make it even hotter. Picking my stolen treasure up off the desk, I slowly dangled the fabric down until the crotch brushed my cockhead. I let out the breath I'd been holding in anticipation. First contact. Fuck yes. I shut my eyes for a brief while, teasing myself by lifting them up and down along my shaft. A little precum leaked out, and I wiped it away carefully with a tissue, not wanting to have any incriminating evidence for her to find when she wore these next time. I had eyes only for my goddess of a sister and her heavenly ass. Transfixed, I wrapped her silky bikini around my cock and began to pump it. I knew this would be huge and, though I could feel myself teetering on the edge already, I held back, savouring the illicitness of getting off on my sister. This was the first time that I sinned against her in fantasy, and already I knew that I would never cum as hard with any other; she was my heroin. It was almost too much, the added thrill of rubbing something that had been in intimate contact with that ass, that pussy. She was sheer perfection, and I just knew that her pussy would be perfect too. She must be shaven or waxed: her bikini bottom would be too small otherwise. While it was rubbing my cock into white-hot territory, on the screen that goddamn bikini was so frustrating visually. I desperately attempted to undress her with my eyes, visualizing stretching the thing over her ass cheeks and slipping it down her wax-smoothed legs. Suddenly I saw myself at the beach with her, guiding her to kneel down in the sand. I would bring my steel-hard weapon from behind, and punish her for wearing what really should be illegal. And she would love it. I couldn't take it anymore. I saw one long ribbon of pleasure spurting up in front of me, higher than ever before, and then I slumped into my office chair, unable to do anything, but in no pain. The second shot came, and I struggled to keep conscious as the pleasure surged through me. Three. Four. Five. I was too high to recognize that I'd never shot so much in my life, and rode each wave with choked cries of "Libby, Libby, Libby!" before I passed out. * That was the first time anything like that had happened to me while masturbating, but then I'd never had wank-material that good before either. I came to after a few minutes, and somewhat groggily began to wipe the cum off myself until I glanced at her bikini, which had stayed wrapped around my now-softening erection. Libby's bikini. Guilt hit me like a thunderbolt. What had I done!? You masturbated to your own sister, you sick fucker. And so much for keeping it clean; the material was soiled beyond belief with my incest-tempted cum. White streaks gleamed brightly on the black fabric. I got a little panicked, and after changing into fresh clothes, I hurriedly carried it into the bathroom to wash out the damage. I had just finished borrowing Libby's blow drier to complete the cover-up, and was walking toward her room with much self-congratulation at hiding the evidence, when I heard footsteps in the kitchen. Cursing, I realized that whoever it was must have come in unheard because of the blow drier. Quick as a flash I raced into her room, buried the swimsuit bottoms, and went out to meet whoever it was in the kitchen with carefully affected nonchalance. "Hi Matt!" Libby greeted me chirpily. "The movie was good..." I didn't even hear the name of the film as she launched into nine reasons why I had to see it. I was too busy trying to hide my guilt, and could hardly look at her. "...so Chloe's staying over tonight, okay?" Suddenly I zoned back in. "Chloe's here now?" "Um, yeah. I said we came back from the cinema together." She seemed a little miffed that I obviously wasn't paying attention to her. "She went to get you from your room just a moment ago, actually." For some reason I felt vaguely uneasy, but then Chloe emerged from the hall, grinning at me. Grinning widely actually. That unease grew a little. "Hi Matt!" She sounded almost the same as Libby -- a product of their long years of friendship -- although perhaps pitching her voice a little higher, a little more girlish and flirty. I bet she knew I had a crush on her. We chatted for a while, mostly about their upcoming college. My concentration was still shot both from guilt and the fact that my dick hurt following the massive orgasm that I'd had. My sis was a bit nervous, but Chloe seemed excited and bubbly. She was always the more adventurous and outgoing of the two, and soon had Libby giggling at her enthusiasm. "Finally we can dress however we want!" she proclaimed happily. "No more potato sack schooldresses!" "Oh yeah, I'm so glad to be turfing those out. But now I have to worry about what to wear every day!" "Honey, you'd look great in rags." Chloe simpered. "Wouldn't she Matt?" At this she glanced over at me with a lecherous look. Did she know? I nodded dumbly, earning a shy smile from Libby and a gleeful one from Chloe. "Or you could just go naked! Everyone would love that!" Chloe pressed on, enjoying embarrassing my sister. I ruthlessly suppressed the image her teasing words brought on. Libby mock-scowled at her, and smacked her redheaded friend lightly over her tight jeans. "Let's get a mattress organized for tonight." She said to change the topic, walking back to her room. Chloe trailed after her, but not before brushing past me and whispering meaningfully, "I bet you would like that especially..." Open mouthed, I watched them sashay away to fetch a mattress for their sleepover. That uneasy feeling had grown into a mountain of dread. How could she know?! -- Then I remembered Chloe had been to my room. Praying that she hadn't shown it to Libby, I burst in and slammed the door. Sure enough, blazing bright on my computer monitor was the picture of Libby in all her glory. To make matters worse, there was the distinctive smell of cum in the air. Chloe would have put two and two together in a second. I felt sick, but not even that could prevent me from saving the image of my sister to my hard drive before closing the browser window. * Sinning with Sister Ch. 02 Author's note: Thank you so much for your feedback! It really sustains me as I grind through these early chapters. In answer to your question: Not yet. I really want to post the consummation of this story, but the groundwork has to be laid, and in my opinion pleasure delayed is pleasure increased. If you need satisfaction right now, this is not for you. Chapter 2 It was the beach's fault and therefore the bikini's fault and therefore Chloe's fault and therefore not my fault. Plus Chloe had uploaded it to facebook, making it doubly her fault. Yeah, she practically jacked your cock for you. I cursed my inner monologue for interrupting my train of rationalisation. It was a once-off, never to be repeated. I would never cum to thoughts of my sister again. And never cum that much again. I winced whilst trying to stay focussed and wondered if I should say something like "Get behind me Satan..." It would be a test of my character to resist, maybe the hardest I would ever face. Hardest indeed! Unsurprisingly, this ruminating wasn't making me feel any better. It was almost a relief when Mom appeared in my doorway. "Are you feeling okay honey? Why don't you come get some breakfast?" After avoiding the girls entirely last night and turning in early, I'd been lying in bed for most of Saturday morning feeling guilty and worrying that Chloe would spill my secret to Libby. "Um, yeah I'm fine. Just sleepy is all. Those two were keeping me up with their giggling." "Well Chloe's gone home now, so you don't have to worry about fixing your bedhead." She gave me a goofy wink before disappearing. Mom had been encouraging my crush on Chloe for a while. I sighed and stumbled into the bathroom. If only Chloe had found her own picture on my computer screen... whilst embarrassing, that would make this so much easier. How could I have been so careless? The one time I masturbate to my sister I get found out. At least Mom didn't seem to have heard about it, which was a relief. God forbid that Dad should ever find out; I'd have to leave town and change my name. After splashing some cold water on my face I steeled myself to face her and strode into the kitchen. I made straight for the fridge, barely glancing at Libby sitting on a stool in her yoga outfit. I yanked the milk out, chucked a bowl onto the bench, and upended the cereal box over it. I stole another glance at her eating a small pot of yoghurt. She caught me looking, but to my confusion was smiling broadly! For a few seconds my heart leapt wildly until I realised that my crazy bed hair was the source of her amusement and that my bowl was overflowing. Clumsily, I righted the box and set about clearing up the mess. "One of those mornings, eh?" She smirked. I grunted in reply, too busy trying to analyse her response for anything else. * We both left the house that morning to get a workout -- she to her yoga class and me to the gym. I'm not a fitness junkie or anything, but at the time I was lifting weights pretty regularly. I had plenty of time on my hands that summer, and the work helped me sleep better and eat more. It wasn't to check out all the toned cardio bunnies pumping away on the cross-trainers. And I told myself it certainly wasn't to bulk up and impress my sis. "How's it going Matty-boy? Ready to pump some iron?" James swung down from the chin-up bar to greet me, and I raised my eyebrows in amusement at his enthusiasm. "What's got you so chipper?" "Scored last night." He shrugged with false modesty, but the effect was ruined by the shit-eating grin that followed after all of two seconds. Although we were only acquaintances at high school, on account of our mutual gym habit James and I had become friends after graduation. We kept each other honest, and I knew that any slacking on my part would invite merciless ribbing from him. About ten minutes in, it became apparent that this was not going to be one of my better sessions. I was still preoccupied with whether Libby knew I was fantasizing about her, and it was showing. On top of this the summer heat -- despite it still being morning -- had me sweating like a pig. James bailed me out on the bench-press for the third time below my rep target. "You been drinking those protein shakes I told you about?" "Yeah man, just an off-day I guess." I replied, shaking my head. "You're never gonna catch up to me at this rate." He warned, as he lay back on the bench to outdo me by twenty pounds and five reps. He was normally the stronger of us two, but not by so much. I sighed and stood toweling off for a minute whilst eyeing the cuties on the treadmills. The row of machines faced the long windows on the other side, which allowed me and any other admirers to go relatively unnoticed whilst checking out their derrieres. For some disturbing reason I kept comparing each bobbing ass to Libby's. It was even more disturbing that I rapidly dismissed each one as inferior. Suddenly I felt a sharp pain on my own backside and spun around to see James gleefully twirling his towel, obviously having just whipped me out of my reverie. "Dude! What the hell?" I exclaimed. "Staring at pussy ain't gonna get it for you bro. Lift the weights, build the muscle, then get the pussy... Now let's do some curls." He swaggered off to the dumbbell rack and I trailed after him, sighing again. It was going to be a long one. * The last of the cool water ran in rivulets down my aching body as I turned off the taps. I'd arrived home before Libby and was glad not to have to wait for the shower. After grinding through that session with James I had started feeling better too. Based on Libby's reaction to me this morning I thought that Chloe surely hadn't told Libby my secret. I felt a growing sense of relief. Soon everything would be back to normal, including my fantasies. Unfortunately, my peace was to be short-lived. Towel around my waist, I opened the door to come face to face with my sister, just back from yoga. I think we were both startled. Her eyes involuntarily flickered down to inspect my chest for a moment, before she met my gaze again, cheeks pink. For my part, I couldn't help but admire how the tight lycra clung to her curves. The awkward silence, in which I was simultaneously flexing my muscles and instructing my cock to stay the hell down, was thankfully broken by her. "I'm cooking pasta for lunch." She said. "Just give me a minute to shower." Embarrassed, I quickly moved out of the doorway to allow her to take her own shower. I didn't reply. Irrationally, I felt my anxiety renewed. Not because I was afraid that Libby would find out, but because a little voice in my head kept raising the alternative: that she did know and was glad. No matter how much I told myself that it was stupid, that we were brother and sister, that there was no way she would be glad to feature in her brother's masturbatory fantasies, I kept turning it over in my mind. * "This is excellent Elizabeth." My father beamed at Libby whilst forking another penne tube. And it was good. Much better than anything I could come up with for Saturday lunch. I shoveled it down between slurps of my protein shake, remembering James' advice to load up on the carbs too. Mum gave me a disapproving look from across the table. "Thanks Dad. I was so hoping that this new recipe would turn out right." She continued, "The extra cheese is a little naughty, though. Naughty but nice." She glanced at me slyly and I almost choked. Dad pounded me on the back a couple of times and Mum went to get me some water. With watery eyes I peered over at my sister, who continued eating in a most ladylike fashion, smiling to herself all the while. If I had been anxious before, it was nothing compared to after that. That afternoon I tried reading, but after scanning the same line for twenty minutes I dismissed any mental effort as futile and switched on the TV. She knows. She knows. She knows. It reverberated around inside my skull, drowning out the sounds of the game on the screen. Finally, I realized that there was only one thing that would de-stress me sufficiently. Masturbation temporarily cures anxiety just as much as lust. I just had to stay away from thoughts of my sister. Easy peasy. Before long I was sitting in front of my computer with a nice wholesome porno flick unfolding on the monitor. I pumped away for a few minutes, successfully avoiding thinking of Libby, but not really getting anywhere. I expelled a long breath of air and changed to some girl-on-girl. Still no satisfaction. Her picture is right there. I refused to surrender and changed again to a blowjob scene. Then a threesome. Fisting. Hardcore anal. Lesbian daisy-chain orgy. It was no use, like I was wearing a cock-ring or something. A knock at the door startled me. I alt-tabbed and yanked the front of my shirt down over my cock just in time, as Libby opened the door. Fortunately, my chair was facing away from the door, which also helped to conceal my flustered state. "Hey Matt." My alarm must have shown in my face, because she then asked "I'm not interrupting anything, am I?" I pulled my headphones off before replying. "Nope. Just looking at, ahhh, online poker." I cursed the popup advertisement that now adorned my screen. At least it was better than Libby seeing those pornstars lying in a circle of cunnilingus. "Will you take your little sister driving? Please?" She asked in her little girl voice, smiling. When she asked for something in a way like that, any male would be wrapped around her finger. "Sure, I'll be right there." I replied, resigning myself to a massive case of blue balls for the next few hours. * At length, my cock softened enough for me to emerge from my room. As we climbed into my old Toyota, I noticed that her filmy sundress rode up really high when she sat down. Her thighs showed that her tan was coming along nicely this summer. I winced inwardly, drew a deep breath, and resolved to keep my eyes firmly fixed on the road. Oh god, even the smell of her was intoxicating in that enclosed space. For good measure, I put the mapbook on my lap. "Gearstick's kinda stiff today." She frowned. I pointedly looked down at her slender fingers wrapped around the stick, trying desperately not to stare at her nearby thighs. Wait, what did she say? Practically massaging the thing with her small hand, she looked up at me for help. "Will you show me how?" Jesus. I swallowed uncomfortably and placed my much larger hand over hers, guiding the transmission into reverse to back out of the driveway. Moving my hand off, I casually put it on the mapbook and pressed down to suppress my rising erection. Fortunately, she didn't try anything else like that again. I was doubly glad she didn't ask why I needed a mapbook for our hometown. Libby had been learning how to drive for several weeks now, so my job in the passenger seat was basically babysitting her as she practiced cruising around the suburbs. With the air-conditioner on max and the gentle sounds of the road I was eventually lulled into a kind of semi sleep. She seemed to be contemplating something. "Matt?" She said softly, breaking the last hour of peace. "Hmm?" "Why were you avoiding Chloe last night and this morning?" Figuring that playing dumb was my best defense I replied, "Was I?" "Oh come on! You always try to hang out with Chloe when she comes over. Remember that time you pretended to be interested in Love Actually so you could sit next to her on the couch?" I frowned, remembering how they had giggled at me after that. "Don't you like her anymore? If you keep stringing her along and don't ask her out, as her friend I'm going to tell her to move on." She said it quietly but firmly. Whoa. Where did that come from? At that point I became very confused. Everything today had pointed toward an attraction between Libby and me. Why was she suddenly bringing up Chloe? It made me doubt my previous conclusion that Libby knew about my fantasy. Maybe I had been imagining all those innuendos. I did like Chloe; always had. At first I had told myself she was too young, but then as the years went by and she'd turned eighteen, I figured that she was way out of my league and just enjoyed teasing me. If anything, she was the one stringing me along. I realized that if by some miracle the gorgeous redhead was into me and I had found out a month ago, I would have been simply overjoyed. But now that Libby and I... I shoved the evil out of my mind and resolved to get up the courage to ask Chloe out. Not only was she a dream girl, but if we got together maybe I would stop having these thoughts about my sister. Although driving, I could tell that Libby was still waiting for a response. "Um, yeah I do like her." "Promise me you'll do something about it." "Okay." She looked hard at me. "I promise." * For the second night in a row I felt like crap; both because I was nervous as hell about asking Chloe out and because Libby's behavior was so contrary. Worrying about it was draining me. And for the second time that day Mum interrupted me pondering my sister whilst lying in bed. "I know you're tired Matthew, but would you please take your gym clothes out of the downstairs bathroom and put them in the laundry?" She said it somewhat apologetically seeing as how I had already turned in, but I was glad of a distraction. "Sorry mom, I forgot. I'll put them away." I could see why she'd asked. The bathroom was already starting to smell pretty funky. Left overnight, something would probably be growing by morning. I padded into the adjacent laundry to chuck the stuff in the washing machine. My gym shorts landed on the other dirty clothes, right next to something I could not fail to mistake as a pair of my sister's panties. Equally unmistakable was the creamy stain running up the crotch. They were on the top of the pile, which meant that they were from this afternoon. The car. I stared and stared for a whole five minutes, until I suddenly slammed the lid of the machine, and tore myself away. I practically ran back to my bed, trying to force myself into the oblivion of sleep. This is what happens when you lust after your sister. Through the pain of my headache I reflected that I was discovering the meaning of the old saying, "No rest for the wicked." * Sinning with Sister Ch. 03 Author's note: This chapter is 30% longer. Small improvement, I know, but I find it hard to write anything that's not entirely sex =D. There is some action in here, but once it hits the true incest the story will get longer. P.S. I am holding back on the dirtiness for now because it is our hero's first time. P.P.S. Our friends Matt, Libby, and Chloe are in the Southern Hemisphere, so Valentine's Day does occur at the end of summer. Chapter 3 After one of the strangest and most angst-ridden days of my entire life, things then reverted almost back to normal between Libby and I. I still wasn't sure whether she knew the whole story about my fantasy, but I had to assume she knew something; whatever the case, we didn't speak about it. Neither did Chloe, who gave no sign of caring that I found my sister attractive. There were no more innuendos, no more flirting, and no more checking each other out. It was definitely for the best, as nothing could come of an attraction between brother and sister. I told myself that what had happened could be explained by inappropriately expressed primal urges. We seemed to have a tacit agreement between us that the events of that day had been a huge mistake. It might have been an anticlimax, but the thought of there being an actual climax was both exciting and terrifying. I channelled my energy into my girlfriend. That's right: I had a girlfriend for the first time. Chloe made it easy for me to ask her out, probably because my sis had already confirmed my interest to her. One day at our place she casually mentioned a movie that she wanted to see, and also how it was a shame she couldn't go with Libby because she had already seen it. I nobly volunteered to go with her and her smile lit up the room. How different life is when you are in love! Your body feels lighter, the colours of the world are brighter, and all the clichés are new again. I realised that I had been waiting for this my entire life, and I was happier than I had ever been. I was learning things too. For someone so outgoing and flirty, Chloe had a surprisingly vulnerable and self-conscious side. She told me she had been waiting for me to ask her out for almost a year. Libby helped me to understand the basic points of being a boyfriend several times in small but important ways. Towards the end of the summer, when Chloe and I had been dating for a couple of weeks, she reminded me the day before Valentine's Day to get a gift, which was something I had never celebrated before. Overall, my sister seemed ecstatic that we were finally together, but in the quieter moments, when she thought that I wasn't looking, I noticed her smile flagging. I realised that since her best friend and brother started dating she would feel a little left out. We did our best to include her in activities when we could, and she still spent time with each of us alone, but it was impossible for things to be exactly the same. Aside from working at my part-time retail job, I largely spent the rest of the summer with Chloe, smiling goofily, holding hands, and making out. Libby gradually began to hang out more with her other friends. She also seemed slightly stressed, but I put this down to the approaching start of university – something that none of us were thrilled about. * The majestic old university had seen generations pass through its halls, and under the night sky the new year's freshmen celebrated the beginning of their college life with a concert. Some danced in front of the stage, others crowded around the long tables serving drinks, and the quieter ones – that included Chloe, Libby, and I – were sitting on picnic rugs and fold-out chairs further away on the grassy oval. From this distance the music was just the right volume. I remembered my own fresher concert a few years back and reflected how much nicer the present was. Back in first year I had been too shy to enjoy myself; but that night I sat on the rug and tightened my arms around Chloe, enjoying one of the last balmy summer evenings. We had been dating for about a month, and frequently cuddled up together in front of the TV or whenever else we got the chance. Sometimes my roaming hands cupped a warm breast or firm piece of ass, but we hadn't got much past that. This was not for a lack of effort on Chloe's part, however. She had become more insistent as our relationship had developed and her outfits frequently bordered on the indecent. I clearly recalled a particular incident in which she had guided my hand up underneath her ludicrously short miniskirt, only for me to pull it back and make an excuse, much to her frustration. Likewise, with a veritable mountain of willpower I had stopped her from rubbing my cock through my pants yesterday, only just preventing a humiliating accident. I know this sounds crazy, but I was the one holding out on her. Despite the fact that I had fantasized about her countless times, once I knew that I could have her I was afraid of messing it up. At that time my sexual education had consisted of a few crappy "Keep your dick clean, yada yada yada..." lessons from the school nurse and what I had seen in porn. Neither seemed applicable in real life, when I was holding this amazing, willing girl in my arms. Between tender kisses I noticed that in the evening her eyes were a deep green. Mischief sparkled there and she pecked me on the ear, sending us both into happy chuckles. I vaguely registered looks of envy from other guys sitting nearby and smirked at them when I caught them looking. Libby had been getting more accustomed to seeing us like this, but was still not completely comfortable. She went to get a drink with Kate, another of their school friends who happened to be there. Chloe leaned back onto my chest and we watched Libby walk over to the temporary bar. Her legs were right at eye level for those guys who were sitting. Heads were turning. We laughed at seeing one staring guy squeal after getting pinched by his indignant girlfriend. "She's so beautiful." Said Chloe suddenly, in a way that implied "Don't you think so?" Although most of the male audience were simply disappointed when Libby reached the drinks table and stopped walking, a few of them jumped up eagerly and strode after her. I tensed up slightly as they approached her, watching as they obviously fought over who would get to buy her a drink. I was on full alert again; well aware of the direction Chloe could be taking. She looked at me, and I shrugged as if to casually say "Well sure." I think we both knew that I was implicitly pleading with her to keep up our silence on the topic of my Libby fantasy. She wasn't letting me off that easily, however, and said with a cunning smile "If, hypothetically, she wasn't your sister, would you feel...?" I cut her off abruptly. "She is my sister." Libby, for her part, was looking somewhat frightened at all the male attention. Thankfully Kate said something that made them back off, crestfallen, and I relaxed. A few seconds of silence followed whilst Chloe digested my blatant evasion of the question. Then, so quietly that I barely caught a word, she whispered cryptically to herself "...harder than I thought." * Deciding that it had to be either James or Libby, in the end I chose my sister to avoid the mockery I would doubtless have to endure with the former. I had resolved to ask her how not to make a fool of myself with Chloe. It was the last Saturday before college started, the day after the concert, and she was baking a cake. She'd been cooking quite a lot that summer and, judging by the smell wafting out of the oven, all that practice was paying off. Mum and Dad were out walking, so I took my chance. After a lull in our conversation about the campus cafeteria food I cleared my throat uncomfortably, causing her to look up from the mixing bowl. "Can I, ahh, ask you a question?" – Man, this was awkward! I could already feel my face growing warm. She smiled at me curiously. "Of course. I've been hounding you all summer with questions, silly." I'm so glad that you brought Chloe and me together," I began, "but now things are getting more serious... you know...?" She looked at me curiously; I was going to have to say it. "...physically." Once I'd said that the rest came faster. "We kiss and stuff, but she wants me to take the next step and I want to do it right." She stirred her icing mixture with undue concentration. "I've never been with anyone, Matt." She said in a very small voice. "I don't know if I can help you." "I just want her to enjoy it and I don't want to hurt her." I concluded. She kept her eyes averted, I saw her swallow, and when she spoke her voice was soft and husky. "So you want me to tell you what girls really like?" It was a rhetorical question, but hearing her say it charged the atmosphere. She glanced up coyly and I nodded. "Be gentle. Touch her all over and find out what she likes." Libby's voice caught and I felt my breathing grow shallower. Part of me realised what a stupid idea this was, asking my sister how to touch my girlfriend when I was repressing my attraction to her, but mostly I just wanted to hear more. "Keep going please." I encouraged her. "Take care of her first, and do it slowly." She still wasn't looking at me and resumed mixing slowly, as if in demonstration. "Kiss her, and then kiss her... breasts." I checked out her heaving bosom, seeing that I obviously wasn't the only one having trouble breathing. Her nipples were definitely hard. Virgin little sis is ripe for the fucking. My imagination was running wild, picturing bending her over the bench and eating her out from behind; stripping her naked and licking the icing off her tits; making her squeal, confess to being a shameless slut for her brother. All those repressed thoughts were leaking out and I gritted my teeth to fight them down. "Feel if her pussy's wet." She continued, but had stopped mixing altogether at this point. God I was a fool for thinking that I would ever be over her. The tension in the air was thick and hearing those words coming out of her moist pink lips was unreal. Our eyes met across the kitchen bench. Her pupils were dark and inky, and there was a wildness there that shocked me. "Then you can touch my..." Freudian slip. We stared at each other. "...her clit." Saying this she lifted her icing spoon, stuck out her tongue, and licked it sensuously without breaking eye contact. It was as though she was inviting her own brother to eat her out. Somehow "Thanks for the advice" just didn't seem appropriate. It was so out of character that I couldn't believe it; she had actually licked it whilst looking straight at me after practically saying to touch her clit. In a dream I walked around the bench to her side, not stopping until we were inches apart. The proximity was intoxicating, and I could feel her warmth in the air. Nothing else seemed to exist. With the back of my right hand I reached up to her cheek and stroked light as a feather. Her face was so pretty, so flawless, it was just heartbreaking. The skin was amazingly soft and warm under my hand. Her eyes closed in pleasure at my touch and she let out a barely audible moan. The timer on the oven blared loudly, breaking the spell. A distraught expression came across her face as she seemed to realise what we had done. She ran off to her room and I stood there, stunned and painfully hard. * Five minutes later she had reappeared briefly and mumbled something in passing about catching up with Mum and Dad on their stroll at the park. As the front door slammed I sat on the couch and held my head in my hands. I'd thought that I was committed to suppressing this thing, whatever it was, between us. Now I was questioning my resolve. Had I wanted that to happen? You asked your baby sister how she would like to be fucked, dumbass. Another wave of debauched thoughts assaulted me, even more sinful than the last. I pictured myself savouring her for hours on end, teaching her how to suck her first cock, and pumping her anus full of cum. My carefully constructed denial was falling to pieces. I massaged my temples, willing the images away, but they just got worse. In the most vivid one yet I envisaged her bent over my lap, naked but for a pair of tiny silk panties. Suddenly Chloe appeared and was spanking the living daylights out of her, spanking right onto the spreading stain over Libby's pussy. Then I realized that my sick fantasies had shown me the solution. Chloe. * I broke the limit, ran the lights, got hooted at twice, and flipped off once, but thankfully didn't get pulled over by the cops. However, I figured that leaving my cock unattended for those few minutes I saved would be more dangerous for me and Libby both. I pounded on Chloe's front door until she answered. "Hey boyfriend..." I pulled her into a long and forceful kiss. We pulled back, panting. "Are your parents at home?" "No." She replied, still bewildered. "Good." And then I was kissing her again until she kissed back, tangling her fingers in my hair. Her tongue slipped into my mouth and I sucked on it sensually. We had never kissed like this before, but this time she could sense my intent, my animal hunger. I picked her up bodily and powered up the stairs, mentally noting never to complain about James being a slavedriver ever again. Within moments I had tossed her on her bed, scattering the handful of soft toys across the pink sheets. "What's gotten into you?" She asked with awe in her voice. "I need you Chloe." I said simply. I didn't add: Because my sister's a fucking tease and I can't stop thinking about her. I pulled my shirt over my head and saw that she had peeled her top off and was working on her short-shorts. The bed was a little too small to be ideal, but it held my weight as I climbed on the end and yanked her pants off the rest of the way. She fell back and I climbed over her, drinking in the sight of her taught body for the first time, clad only in lacy underwear. Her flaming hair fanned out over the pillows as I towered above her. God she was exquisite. Remembering the advice I had paid so dearly for just minutes ago, I wound back the pace and kissed her gently whilst sliding my palm up her thigh, over her ass, and up the curve of her spine. Chloe's skin on mine was soft and supple. Wherever I touched it the fiery nymph burnt me. I was so sensitive from having never done this before, having never been so close to someone before. I discovered that it tasted amazing too as I kissed her down her neck. She arched her chest up towards me and her breasts brushed my chest through her bra. Chloe surprised me by rolling us over and hurriedly unclipping her bra. Then with a wicked smile on her face she planted her hands on either side of me, leaned down and grazed her naked nipples on my chest, hissing sexily at the contact. I began to realise that Chloe's idea of good sex might not be as gentle and romantic as my virgin sister's. There were no objections on my part, and overall she was doing a wonderful job of distracting me from the incest fantasy. I reached up and hefted her full tits in my hands. In response she lifted her elbows up and held her hair back with both hands, exposing herself to me fully as she straddled my torso. Starting with my fingers spread in all directions, I slowly brought them in to squeeze her nipples simultaneously. "Oh fucking play with my tits." She moaned. I obliged diligently for several minutes until at one point she slid back enough for my cock to hit her butt, clearly begging for attention. Chloe grinned as she ground her ass against my cockhead. "Ooo what's this?" She laughed as I fought down the incredible sensations her butt was producing. Feeling the need to take back some control, and determined to satisfy her first, I stroked between her legs, right down the middle of her panties. My reward was a slick sensation on my palm and her sharp intake of breath. Thankfully, she stopped grinding on my cock whilst I rubbed her softly. "Mmmm yeah." She closed her eyes and bit her bottom lip in indulgence for a moment. "We should have done this ages ago Matt." I'm sure my technique wasn't the best, but she was cool enough not to draw attention to my lack of experience. All she did was pull my fingers up a little higher on the now-moist material. I worked and worked whilst her body and breasts swayed rhythmically above me. Her hands yanked mine away just when her passion seemed to be reaching fever-pitch. Glowing green eyes regarded me with a burning intensity. "Do you know why I did that?" She croaked, barely still in control. One hand seemed to be holding the other, trying to stop it from finishing herself off. "Why?" I said in wonderment of her. "Because this is going to totally wipe me out and," she took a shaky breath, "I want to be naked with you inside me." "What about con..." I began, but she cut me off in frustration, almost crying out with "I'm on the pill! Please hurry." We changed positions once more, I finally released my cock from the confines of my boxers, and then I reached to peel her panties away. She was suffering in a purgatory of frustration, already halfway to heaven, but not quite there. Even that simple act of undressing caused her to let out a moan in sheer pleasure as the fabric slid over her pussy. I stared at her glistening core. Her widely spread legs revealed that she was flawless and pink, not a trace of hair anywhere. The flesh was swollen with excitement, and a droplet of moisture ran down one lip to wet the linen. Of all the guys she had met, I had done this to her. "Matt!" It was almost a shriek and snapped me out of my inspection. I held my throbbing manhood carefully, knowing that I would not last more than a few strokes inside Chloe, my first. She was staring at it hungrily, and at that moment I'd never felt so potent, so masculine in all my life. I positioned and she wrapped her arms around my shoulders intimately. Slowly I penetrated her until I was fully inside. This was sex as it was meant to be, with slick wet pussy and rock-hard cock. She whispered hoarsely in my ear. "One more baby." I took her again and then she was cumming, clinging to me for dear life whilst her walls fluttered around me. It was more than I could bear. I fired home, deep inside her as we became one for the first time. * Author's note 2: I've been thinking that I should switch over to a sex-only incest story. By that I mean skeleton plot only with minimal teasing. Personally I like a teasing sister, but I aim to please you. Leave an anonymous comment if you would prefer that. Sinning with Sister Ch. 04 Author's note: I got a job. Then I lost said job in a week. Now I am back to writing. Thanks for your patience, and thanks to everyone who encouraged me to keep the plot going (with plenty of sex to come, of course!). Chapter 4 In the first lecture of the semester, when I saw Justine sitting right at the front, I realized I'd been hoping all summer that she wouldn't be taking this unit. In the afternoon I was dismayed to find that not only was she taking the unit, but she was also in the same tutorial group. It was rotten luck, but I consoled myself with the fact that this was the last year. Then she would take her major in international business, disappear into her father's business empire, and leave us commoners in peace to get regular day jobs. I closed my eyes and took in a deep breath. If I focused hard enough I could almost recall Chloe's sweet scent. The thought soothed me, but the others were watching and I had to answer the bitch soon or back down. I'm ashamed to say that I resorted to an ad hominem argument. "Fair to you maybe, because you know so much about being an average worker." I glared at Justine from across the table in our tutorial room. Naturally, she wasn't going to let me get away with that and retorted swiftly in her crisp, clear voice. There was a trace of a British accent in it, a sign of her exclusive private tutoring. "Since you are resorting to a sarcastic personal attack, you must consider my point inarguable." Her smile of victory, although decidedly fake and designed to irritate, was dazzling nonetheless. Damn it, she was so smug, it made my blood boil. The worst thing about her was that she had every reason to be smug, not least of which was her amazing appearance. I hated to admit it to myself, but she was beautiful. I told myself I wasn't attracted to her though; that would be like surrendering to the enemy. The tutor, a small and learned gentleman in his sixties, was clearly taken aback by the hijacking of his agenda by two students. He tried -- for what must have been the tenth time in fifteen minutes of otherwise continuous argument -- to move past the unexpectedly rocky issue of industrial relations law. "I appreciate the, the, erm... enthusiasm with which you have discussed the issue. However, the primary point I was trying to make is that regardless of..." I zoned out, figuring that he was just repeating what our lecturer had said already, and went about trying to empty my head of all the bourgeoisie bullshit Miss Justine Fox had spouted. She was sitting primly with one smooth leg crossed over the other and was dressed in a black business skirt and white blouse. The material was expensive, obviously. Her hair was in a sophisticated chignon which exposed an elegant neck and her face was inclined attentively towards the tutor. Some said she was a proper lady. I called her the stupid blonde bitch. She was blonde. She was also undoubtedly a bitch. However, she was unfortunately not stupid, which meant that she often had a witty but specious retort ready for me whenever I argued with her appallingly skewed upper-class views. I think she took a kind of sick satisfaction in winding me up whilst remaining perfectly calm herself; she probably thought it proved her superior breeding or whatever. * The transition from car to couch after a day at uni was made with the familiarity of three years' routine. I plopped down heavily and switched on the TV, needing to unwind. My prescribed reading list was already prohibitively long, and the titles were uniformly uninspiring. Almost immediately I began mourning the loss of the holidays and regretting not being more appreciative of the free time. I counted that Easter break was six weeks into semester -- one day down, forty-one to go. Isn't it funny how we don't appreciate what we have until it's gone? I registered Libby coming in the front door. She went straight to her room. It was two days since I had surprised Chloe at her house, and two days since Libby had last spoken to me. Although I knew that it was going to happen eventually, I wasn't entirely comfortable that I had consummated my relationship with Chloe and lost my virginity whilst still hazy with lust for Libby. We were definitely in love and my girlfriend was certainly happy that it finally happened, so what if it was partially a distraction from a fantasy of more sinful fornication? Whenever my thoughts strayed in that direction, I whispered the word "incest" to myself, and it echoed softly in my ears. I just had to protect her, protect us both, from myself. * After an hour or so I hefted my bag and got to work, starting with the macroeconomic outlook article. From the look of things, the think-tank that published it was decidedly right-wing. I tried to picture Justine. She was probably at a mahogany desk in her riverside mansion, already on the last of the articles. Then I mused that perhaps she had a personal assistant to summarize and read them to her. The thought of her one-upping me spurred me on, and I lost myself in the work until late that night, reading until my head felt heavy and the words lost their meaning. I felt the air move and swiveled in my chair to see the door swing open. Relief flooded me as Libby appeared; I was so glad that she wasn't mad at me anymore. Relief turned to desire when I saw that she was wearing a red satin slip, the kind of lingerie that is designed to be removed by a lover. Her expression was both demure and sexual. Seemingly moving in slow motion, she came to kneel before me with her head bowed, fixated on the bulge in my pants. Although a rich brown, her hair shone under my reading light. Elegant fingers opened my fly, and then she was holding me. She looked up with a cheeky expression on her face, winked at me, and then began to stroke softly. Pleasure electrified my entire body as I watched her place her other hand lower down and pump. My hips jerked up involuntarily and my eyes rolled back in my head. I was lost in the moment until she stilled her ministrations. There was no protest from me, because I saw what her intention was. With both hands wrapped around the rigid shaft, her head was moving millimeter by millimeter closer to the exposed end. She breathed a warm, moist breath over my angrily swollen cockhead, causing me to grit my teeth. I put my hand on her head, wanting so badly to fuck her face like an animal, but knowing that I could only plead for more with gentle pressure. Her tongue darted out to moisten full soft lips. Then she was closing the distance... The dampness of a full load of cum in my pants woke me. I sat up slowly, lifting my head off the table and carrying the top page of a report with it. I peeled it off my face, looked at the hole in the page, and figured I must still be wearing several sentences on the emerging economies. My watch indicated it was already two in the morning. What a dream! As I wiped away the drool I had shed for my sister, I wondered if I could be blamed for what happened in my sleep. It wasn't like I chose to dream about her. Still reflecting, I started cleaning up the cum. How much control did I actually have over my attraction to her? Was she just a guilty pleasure for me or was she simply too hot for any straight man to resist, even her own brother? * After the icing incident there was no pretending that nothing had happened. Libby and I were both painfully aware of each other and spent the weeks following that last summer weekend avoiding any time alone together. On one level it hurt me, but I knew that it was the only way. She did her driving practice with Dad instead of me. Across the table at mealtimes she wouldn't meet my eye. Around the house she started wearing her older, more conservative clothes, covering her luscious body from view. The only time I saw her wearing anything revealing was right before she left for class in the mornings. I felt a pang of jealousy at the thought of all those freshmen getting an eyeful of Libby dressed in her short skirts and shorts. I'd even started to worry that she would be looking out for a suitable guy from amongst the many who would doubtless be hitting on her. Perhaps she would take the same route as me: diverting her affections from her sibling onto someone else. Obviously I was feeling more than a normal, protective brother would for his little sister; I was feeling possessive more than protective. That was a concerning difference, but I couldn't bear the thought of someone else touching her, especially touching her the way I wanted to. What actually happened remained a secret between Libby and I. Chloe fortunately hadn't had a chance to observe us together and therefore notice that we were acting differently toward each other, and I didn't want to embolden her exploration of the incest topic by providing fresh incriminating evidence. Mom seemed to figure that our behaviour had something to do with the charred cake she had pulled from the oven on that fateful Saturday, but she merely pursed her lips occasionally, evidently trusting that we would figure it out ourselves. Incidentally, she was still over the moon that Chloe and I were dating. * Once you've had sex for the first time, you realize a profound truth: Since the dawn of time humanity has been frustrated by the necessities of daily life occupying time that could otherwise be spent copulating. Those first six weeks of semester felt like the longest of my life. Chloe and I met up when we could, but it was never enough. Her first year physiotherapy course wasn't too tough; I was the one with the heavier workload. Her relationship with Libby was renewed since the two of them were taking the same course, and they consequently had free time together. I had to let my part time work go. James's jibes about being a slacker eventually devolved into death threats if I didn't show up at the gym, to which I jokingly replied that death would be welcome relief compared to facing another paper. I simply didn't have the time, but I figured I got plenty of exercise with Chloe anyway. I saw her every weekend, and attempts at romance and conversation were thin as the sheer possibility of finally being able to do it again took over. Chloe led me into a variety of sexual adventures, and each one seemed better than the last. At the time I thought that we were pretty kinky, but I later learnt that she was taking the slow and sweet approach with me; I don't want to jump ahead in the story, but let's just say that I discovered Chloe liked to play the nasty slut. But at this point everything we did as boyfriend and girlfriend was fairly vanilla. So she jacked my cock while I rubbed her clit. I learnt how to judge her closeness to cumming by the telltale signs of breathing, flushing, and hip movement. I almost died when she put me in her mouth the first time. Loving the taste, she swallowed everything I could give her. We tried phone sex once late at night. Her squeals of pleasure as she touched herself expertly sent me over the edge. I learnt how to eat her out and how to bring her pleasure with my fingers at the same time. Flicking her little nub with the tip of my tongue and pressing the rougher spot at the front of her pussy was the fastest way to get her off. And I took her pussy in several interesting positions and locations in the house when my parents weren't home. Libby knew what happened whenever Chloe came over, and tactfully found an excuse to go out on such occasions. My little girl was getting a lot of male attention at college. From the way she looked at me I doubted I had serious competition, but I made sure to keep her satisfied and mark her fair skin with fresh hickies regularly. * The leaves began to color, the days turned cooler, and rain-bearing clouds appeared in the skies for the first time in months. The season suited my mood in those weeks of boring classes and economics work. Suffice it to say that I was glad it was the last year. The other reason to be glad of that was Justine. The bitch just thought she had all the answers and apparently liked to get in my face more than anyone else's. We agreed on nothing, so it was just as well that we were put in opposing debating teams. Sometimes I enjoyed the verbal sparring. It was strangely intimate in a way, when it was obviously just the two of us driving the debate, and tensions were running high. We glared at each other, and when two people lock eyes like that it means they either want to murder each other or jump each other's bones. Her refined beauty led me several times to contemplate the impossible; that she was enjoying it and that we were engaging in some kind of fucked-up intellectual foreplay. Then she would say something unbelievably callous and set me off again. In any case, I like to think I held my own against the glares, cutting sarcasm, and snide remarks. Libby continued her remarkable job of avoiding me, and seemed to be enjoying first year physio. Some nights I saw her practicing her physical examination skills on Mom and Dad, but pointedly never even asked me to play patient. One time I overheard Mom suggesting that Libby examine my shoulder instead of hers. Libby didn't reply, but I shivered at the thought of my sister's touch. Chloe and I proved in those six weeks that our relationship could survive busier times, and I lived for our still relatively tame encounters. However, the events of the Easter break got out of hand, especially that first night. * Justine had narrowly beaten me again and topped the class in the mid-semester exams. I was standing in the hallway of the business faculty offices on the last day of class -- the day on which Easter break began. My eyes lingered on the noticeboard, scanning over the class's results with some interest mixed with impatience at wanting to get home. She was a bombshell with brains, alright. If it hadn't been for the thought of Chloe, I would have reflected on how unfair life was that someone could be smart, rich, and flawlessly hot. Sir Richard Fox was the founder and now majority stakeholder in a multinational retail corporation, so I supposed there was a logical explanation for Justine's intelligence and money. The glamour could be explained by her mother; a trophy wife to the businessman and a former supermodel. All in all, I conceded, someone like Justine was explicable even if not very likeable. I resolved to wipe the smirk off her face in the midyears and spun away from the board. There she was, as though she had been silently reading the board over my shoulder. In that briefest of moments before she could compose herself I thought to myself that she didn't look quite as fierce as when I usually saw her. She didn't seem as happy as most students would be at Easter time either. Then the mask was back. "Pondering something Mister Marshall?" She called me by my last name; it was surprising she even knew that. "Come to taunt me over two-percent, Miss Fox?" I replied with all the sarcasm I could muster, my eyes meeting her icy blue ones. Ignoring me, she hurled an accusation. "You made up those figures." "Sue me." I didn't even bother to deny it, knowing that it would just make her madder. At the last faculty debate I'd bent the truth to develop a point more fully. To cut a long story short, the adjudicating lecturer had been convinced and awarded my team the victory. It didn't matter that it wasn't worth anything to our grade; I enjoyed beating her no matter how small the stakes. She flushed, seemingly infuriated at my apparent lack of respect for the rules and remorseless attitude. She was even prettier all riled up, and it happened so rarely that I was enjoying myself. Isn't that the main reason you argue with her? "I'll report you." It was an angry whisper. I was mildly amused. "It's Easter and you honestly think the lecturer is going to care about a student debate that happened last week?" I paused and thought to myself: For that matter, why doesn't she have anything better to think about? She broke the stare after a second and her pumps clicked loudly on the floor as she strode towards the door. The bitch had nice legs. I watched as she climbed into the passenger seat of a waiting sports car and disappeared from view. Pulling out my phone, I pushed the speed dial for Chloe. "Hey babe, you finished?" * Author's note 2: Next chapter already submitted and coming out in two days. Something significant will happen in the Easter break. Sinning with Sister Ch. 05 Chloe had caught a lift with her Mom that morning, so I drove down to the physio department to pick her up and take her straight home to my place. "You are totally getting lucky tonight. Plus I have a surprise for you." She grinned at me shamelessly from the passenger seat. Five days had passed since our last encounter, and I was saving it up for her, determined to make our first holiday break together a memorable one. We had ten whole days without classes. Technically, only four of those were for Easter and the rest was a "non-teaching study period". As if anyone would actually study. Except Justine perhaps. I promised myself not to think about her on holiday, and began to wonder what Chloe had in store for the evening. I desperately needed to fuck. Nonetheless, I swatted her hands away from between my legs. "I'll have an accident!" I protested. Chloe pouted cutely, but thankfully didn't make any further attempts while I was driving. I pulled into the driveway to find Dad loading boxes into the trunk of his station wagon. My folks were going away for the Easter weekend to a country bed-and-breakfast. "Hi Mr Marshall!" Chloe chirped. "Looks heavy!" Dad laughed and wiped his forehead, leaning on the car. "His Mom has packed the kitchen sink!" The door only opened halfway due to another box just inside. Chloe and I squeezed in and walked through the hallway, where another stack of boxes sat waiting. I shook my head. Mom did tend to get anxious about trips, amongst other things. I guess that was where Libby and I got our slightly worrisome natures from. Mom and Libby were in the kitchen, discussing meals. Peeping over Mom's shoulder, I raised my eyebrows at the long list of food inventoried there. "There are just two of us Mom." I glanced back at Chloe. "And even if Chloe ate breakfast, lunch and dinner here there would still be too much." Mom turned. "Hello Chloe dear." To me she said "We'll be gone until Sunday week. Your father and I decided to extend our trip to do some hiking on the nature trails." There was probably still too much food in the house and too many boxes in the car, but it didn't seem so ridiculously excessive now. "The whole break?" I felt like leaping for joy. Ten days for Chloe and I to use the house together! Maybe we can do it in the master bedroom. Chloe and I shared a knowing glance, both thinking the same thing. I'm going to tear you to shreds all week, baby. Another part of me realised that Libby and I would be spending a substantial amount of time alone together too, but I tried to ignore that. * "Take care of your sister." Mom said, glancing between me and Libby. She was presumably doubtful that we were friends again, given all the avoidance lately. "Try not to get into too much trouble." Dad followed meaningfully, except he was glancing between me and Chloe. Chloe and I held hands and waved from either side. Libby stood next to Chloe as we watched their heavily laden car drive off towards the setting sun. They would be lucky to arrive before dark. Libby had a date lined up for that night; Chloe told me she'd set it up to give us time alone together. She also assured me that the guy was cool, but that didn't stop me from thinking he looked like a try-hard when he came to pick Libby up. No way was he good enough for my sister. She, on the other hand, was looking spectacular. I could have used all the superlatives to describe her, but it still wouldn't be enough. Her little black dress came down to mid-thigh. When she moved, the fabric seemed to caress her and a handful of tastefully sewn sequins shimmered. She had a perfect waistline. It was something I never failed to notice, but when she wore one of those fashionable waist belts it drove me insane. Her hips were so marvelously curvy that she just radiated femininity. No man could watch her walk away without taking a second, longing look at the sashaying of those hips. Black stiletto heels with thin straps crisscrossing her dainty feet completed the look, perking her ass up and giving her legs a lightly toned look. In typical Libby fashion, she was very nervous, despite looking like a smoking hot goddess. The moment she was out the door I attacked Chloe, thanking heaven I could take out my arousal on a legitimate and willing target. I pinned her against the inside of the front door and kissed her deeply, just the way she liked it before frantic sex. My cock strained up proudly, pressing against her midriff through the clothing. She brought one leg up to my hip, and began to grind on me as we continued tonguing. "Master bedroom." I said breathlessly as we broke apart. She nodded excitedly and we started upstairs, but before we had gone three steps she said "No, wait! I almost forgot the surprise!" She led me down again and we sat on the bottom steps. "The upstairs bedroom can wait another day." I frowned slightly, but she went on. "Okay, for this to work I have to ask you a question: do you trust me?" She looked at me playfully as she said the last part. "Not at all, you little nympho. You almost fucked me to death last weekend." I smirked back, joking. She pounded me with her small fists for a few seconds while we both laughed. We ended up with her straddling my lap, cuddling. I kissed her crown. "Seriously though, I need to know for this." She looked up at me. I was really curious by now, but no matter what it was, I knew she would always do right by me. "One hundred percent." I told her. She beamed at me, then jumped out of my lap and delved into her nearby handbag, producing a black silk scarf. "Turn around and do as I say." * I felt a thrill as Chloe slipped the folded scarf over my eyes and tied it at the back. The soft material was completely opaque. Then she unbuttoned my shirt and slid it off, right there in the hall. As her hands ran over my torso, I flexed for her benefit, and she sighed at my display. "Your body is so hard, I love it." Her praise made me instantly resolve to start hitting the gym again. Then she grasped the bulge in my pants. "And I haven't even come to the hardest part yet. Let's take these off too." I stepped out of my pants, completely naked in the cool air of the hallway. It felt so wantonly sexual, leaving clothes strewn about the house during foreplay. I did feel somewhat unfairly exposed, but then Chloe wrapped her hand around my cock before I could worry about that too much. "Let's go." She held it very carefully, and led me by the cock towards my room. "I feel like a man-slave." I pretended to complain whilst enjoying the sensation of having nothing against my skin except for the scarf around my eyes and her hand around my cock. She giggled, "That sounds like a good idea too, but it isn't what I had in mind." My legs bumped into the bed and she guided me to lie down. Her hands pulled my arms above my head, I heard her opening a drawer, and then there was more soft fabric to bind my wrists to the bedposts. I furrowed my brow in consternation; this was unexpected. She must have seen that I was about to protest, because she kissed me softly and said "The bindings are very thin. Don't worry." I tested them. Whatever she had used, I made a few strands break with ease. Chloe squeaked in alarm and pushed my arms back to stop me from accidentally ripping through before we even got started. I relaxed and let her continue. After a minute, when she had just finished binding my ankles too, I noticed that something didn't seem right. What was it? My bed smelt different to usual -- sweeter. The scarf had Chloe's perfume on it, but as I turned my nose into the pillow I realised this was Libby's bed. My voice was cold as I spoke. "Chloe, what do you think you're playing at? Untie me right now or I'm going to tear these off myself." I began to get up, objecting to Chloe's scheme, but suddenly I heard the bed creak and she sat on my chest heavily, knocking the wind out of me. She yanked the blindfold off. "I know you want her Matt. I'm not stupid." I was silent, and pretended to get my breath back while I composed a denial in my head. "And before you even think about escaping, look at the bindings." My eyes were just beginning to readjust to the light, and I glanced to the side. Shit. "Those are her panties. If you break them she'll find out." Chloe seemed to be enjoying watching me squirm. I gulped. Side tie panties; that explained how they reached around my wrists and the bedposts. Mmm, even better than that black bikini bottom. I told the inner monologue to shut the fuck up while I figured a way out of this confrontation about the incest fantasy. "I suggested them to her." She informed me whimsically. "Sexy, aren't they?" The pair on my left side was a simple and elegant black, but my right hand was trapped by a racy red G-string. Against my will, I felt my cock grow to almost maximum size. I prayed that she wouldn't slide back and discover it poking her in the ass. "Even if I hadn't seen the bikini picture, it's obvious from the way you look at her sometimes. Like just now when she left, you were definitely jealous of the guy taking her out." Was it really that obvious? "We can't keep tiptoeing around this because I know it's gnawing away at you Matt. You have to admit you want her. And yes, I do know that you are hard again." She glanced back at my erection before looking at me intently, satisfied that my member was indeed sufficiently swollen to confirm my guilt. I was ashamed, but couldn't keep denying it. "You don't think it's sick?" Her voice softened. "It's not something I'd tell anyone about, obviously, but I think you'd have to be a robot not to want her. Hell, I think she's pretty fine too." Chloe smiled at the shock that admission gave me, before continuing, "The point is that practically all guys want her. But I think she only wants one guy: you." Something inside me was dancing wildly, but I suppressed it and struggled against the improbability of the whole scenario; my girlfriend tying me down and forcing me to admit my desire for my sister. Then something else struck me. "Even if you're right about Libby, what does this mean for us?" She laughed. "Libby's the one who set us up in the first place. She's the sweetest person I know, and you two innocents would be so cute together. But it's not like she's going to replace me as your girlfriend or anything, and I don't want you to have to choose between us." I was so grateful, so full of relief that this beautiful girl above me had put my fears to rest. Libby still didn't know, but just talking about it and being acquitted by Chloe made me well-up with joy. Reserves of tension and guilt I hadn't known existed evaporated and left happiness behind. "I love you no matter what Chloe. You know that, right?" Her response was to lean down and kiss me tenderly. "I know." "Now let's enjoy this." * She was the rarest kind of redhead; naturally fair but with flawless skin, green-eyed, and slender. I gazed longingly as she undressed for me, provocatively and piece-by-piece. First her peach-coloured tank top, then her denim shorts fell to the floor. She pirouetted gracefully in a pink bra and panties, sending her long hair shimmering through the air momentarily before falling to the middle of her back. I admired her beauty with new appreciation. Beautiful both inside and out. Coming up alongside the bed and turning away from me, she bent right down to her toes with ease. I wanted to touch those taught, creamy cheeks so badly. She shimmied out of the pink lace, and I strained as far as I could towards her now-exposed pussy. Her sex was just starting to redden and swell, like a delicate flower about to bloom. It was so maddeningly explicit. My mind was running a continuous loop, primal instincts chanting out at me one thing: Fuck, Fuck, Fuck, Fuck, Fuck. "Untie me Chloe," I croaked, "let me take you like this, from behind." "Ah ah ah! You have to do as I say, remember?" I blew a sharp breath of air onto the pink folds. She yelped in surprise and jumped away, laughing, chiding me. "Just for that I'm going to make you wait until I've had mine." -- I loved how she took what she wanted in the bedroom. She unclipped her bra and tossed it carelessly onto Libby's chest of drawers. Kneeling down, she held her breasts in her hands and fed a rosy nipple into my waiting mouth. "Mmmm. Suck it baby." In no time at all I had the skin pebbling and firm under my tongue. I grazed it very lightly with my teeth. She drew back at first, but then tossed her hair to one side and eagerly leaned down again, moaning her approval while she tweaked her other bud between finger and thumb. Chloe had fantastic breasts. They were large enough to give a guy a handful, but without being at all saggy or out of proportion. We spent several long minutes that way, me laving away with my mouth and watching her pleasure build until she needed something more. She climbed onto the bed and swung a long leg over my chest, sitting down more carefully this time. I inspected her glistening pussy. It was close for me to smell that delicious feminine nectar. She scooted up closer and closer until I could almost reach it by straining forward. Then I realised that she wasn't coming any closer. "Let me eat you." I pleaded. "Payback's a bitch, isn't it?" She teased. "This is your punishment for blowing on my poor little kitty when she wasn't ready for it." And then a she ran a finger down her cleavage, trailing it round and round for my benefit, until it came to rest on her clit. She let out a sigh as she lingered for several moments before delving inside herself. I saw no resistance at all from her slick channel. The finger came out glistening and she painted my lips with the juice before kissing it off. "I taste goooood." She cooed. I could only nod in absolute agreement. That little sample had only enflamed my appetite for her. The scent of her permeated the room and filled my lungs. With two fingers of her left hand, she parted her pussy lips up high and pulled back gently until her clit poked out from under its hood. Her most sensitive place was laid out defenseless, so close I could almost lick it. Just a few more millimeters. Then she bit her lip and gingerly caressed it with the pad of one finger, sending her body instantly tense. I felt her thighs grip my chest hard and heard her stifle a scream. After adjusting to the sensitivity with a few more careful touches, she began to masturbate in earnest, right there on my chest. It was insanely hot. That finger diddled up and down, left and right, and she began to pant. Her pussy began to make occasional obscene squelching noises as she jiggled in pleasure. Several times she plundered her pussy to gather extra lubrication for the dirty deed. Five minutes in, she squealed as her orgasm struck. She grabbed the headboard just in time to stop herself collapsing on top of me. Her breasts heaved overhead as she sucked in air to recover. Juices now trickled across my chest and onto the sheets. I was beyond caring about the mess at this point, though. I just needed to taste it. "Ohhh Chloe." I moaned. "It's going to waste." To my dismay, she simply smiled and started probing herself again, apparently unsatisfied with one orgasm. She worked furiously this time, even having to change hands midway to give her dominant hand a break. Her swollen folds wobbled to and fro under the assault and the immense effort had her hot and sweaty. By the end, she was grabbing one breast and licking her own nipple as she brought herself to a powerful climax. Her whole body shook above me as she squealed yet again, screwing her eyes tight against the sensations she was producing. "Please Chloe." I begged. I wished I could cum again that quickly. She still hadn't let go of the headboard but she lifted her hips up and finally brought herself over my mouth. "Third time's the charm," she whispered, "make me cum." I stuck my tongue out as far as I could and lapped firmly through her folds. The sweet taste exploded in my mouth, and we both moaned our appreciation. I licked her completely clean, eating my fill of her, unable to get enough of her sex. She rocked back and forth gently, riding my face and trying to get some tongue on her clit by timing my strokes. I was deliberately avoiding the little bud, however, wanting to inflict some sweet torture of my own. Driven insane after several dozen failed attempts to get me to lick her favourite place, she pinned my forehead down with one hand and demanded. "Finish me off or I'll just leave you here." Her voice was ragged, and although I knew she wouldn't actually carry through that threat, the meaning was clear: she just couldn't take any more without cumming. When I sucked her clit into my mouth and swirled my tongue around as fast as I could, she just broke. She screamed so loudly I was sure that she would be heard three houses down the street. After some long and convulsive spasms she slumped, clinging to the bed frame for dear life. Her pussy was resting heavily over my mouth and nose; it was actually getting difficult to breathe. I nudged her and she lifted up as quickly as she could when she saw my predicament. She laid her tired body up against my side and held me close to rest for a while. * While the rest of me was very comfortable laid out spreadeagle on Libby's bed and kept warm by Chloe, I was bothered by two things: my face was still covered in liquid pleasure and my balls were beginning to ache. I still hadn't cum, whereas my greedy girlfriend had had three already. "Chloe?" I whispered. Thankfully, I felt her stir. She opened her eyes and smiled at me. "Would you wipe my face please?" She giggled and lapped at my cheek once, but there was way too much mess for that. "Hang on a second." She glided out of the room and soon returned holding another pair of panties. Her next announcement startled me. "This pair was already in the dirty laundry, so no one will notice the girl-cum." Before I could stop her, she was wiping her cum off my face with my sister's underwear. The panties were of the black side-tie variety, just like the ones around my left wrist, but these were used. There was a shiny mark where Libby's pussy-slit had stained them. "This was the cleanest-looking pair I could find. She must be touching herself almost every day." I could smell Libby's pussy flavour; it was pure heaven. My cock gave several involuntary throbs as her words evoked images of Libby uninhibitedly caressing herself to orgasm. "Don't worry, I haven't forgotten." With that, she dropped them on the pillow next to me and her hand brushed down my chest to wrap around my cock, jerking sensuously. "So you like that we're doing it in Libby's bed?" She teased. "It's so wrong." I sighed, half in pleasure and half in disbelief at what she was saying. Her hand stopped moving. "But yes, I have to admit that makes it even better." I said reluctantly, knowing that she wanted to hear the truth. She started stroking again, rewarding my surrender to the incest taboo. "And do you like her teeny, tiny, panties? Do you approve of your little sister wearing those things?" The sight of that red G-string tied around the right bedpost would be forever burned into my memory. Through gritted teeth I hissed a "Yes." "Pardon?" She wanted me to say it louder. "Yes I fucking approve." My voice cracked. "I fucking love it." "Mmmm you're a bad boy." The speed of her ministrations increased. "Have you ever fantasised about her blowing your cock?" She asked impudently, with no shame at all at the forwardness. Sinning with Sister Ch. 05 I looked away, and she let go entirely. I choked back a howl of disappointment, torn between needing her to continue and wanting to conceal the depths of my transgression. Finally, I nodded almost imperceptibly, so ashamed at myself and yet so exhilarated to be admitting my fantasies to Chloe. "I thought so." She said happily, recommencing with long, full strokes up and down my shaft. "Want me to do it now?" "God yes." That was exactly what I needed. She clambered eagerly between my legs and knelt down, licking her lips lewdly. "Just shut your eyes and pretend I'm Libby." I did as she asked, turned my head, and buried my nose in my sister's panties. Chloe teased me for what felt like over an hour. Warmth enveloped my cockhead again and again while she used her hands on the shaft. I imagined not a redhead, but a brunette servicing me. Servicing her own brother. Silky soft hair fell gently onto my balls with every bobbing of her head. Her sucking and humming sent me into another realm of existence where every part of me swam in ecstasy. But she knew my body and made it last. I was begging for release at the end, desperate to cum. She stopped right at the peak. I opened my eyes again and saw her holding my cock gently to observe precum weeping out the end. Her tongue flicked out to catch it, almost sending me over. Then her impish expression was back. "Say her name and I'll deep-throat you." I was in no position to argue, even if I had wanted to. "Libby." I said. She went as deep as she could. Fucking hell. "Libby." Down. "Libby!" Again. "Libby, Libby, LIBBY!" I chanted hysterically. Swallow, swallow, swallow. So goddamn close now. Chloe came up for air, panting. Then I heard footsteps on the carpet followed by a gasp. * Libby blushed brightly and her mouth opened wide in surprise, but she didn't back away. Her eyes landed straight on my very erect organ, smack bang in the middle of her bed and covered in drool. I didn't think she'd ever seen a penis in the flesh before, and she stared at it for a good thirty seconds, stunned and apparently unable to look away. I was horrified, yet my erection didn't flag one bit at her discovery. If anything, it grew somewhat harder and larger with my sister watching it, something I'd thought impossible after all of Chloe's ministrations. I was so hard it was actually starting to mix pain with the pleasure. She was back early from her date; presumably it hadn't worked out. She was still all dolled-up and looked sensational. Libby usually came home quietly because she knew that we would be together and didn't want to disturb us. However, she obviously hadn't expected us to be using her room instead of mine. I looked at Chloe, who shook her head indicating that no, she didn't plan this. Nonetheless, she was clearly delighted at being caught. Chloe broke the silence and said "It's bigger than you thought, isn't it?" Libby tore her eyes away from my cock to look at Chloe. She then registered that her best friend was completely naked and that her chin was dripping. A hand came up to cover her mouth. Chloe didn't shy away at all from Libby's gaze. Instead, she got up and pulled her towards the bed. I watched as she guided Libby closer towards me. To my surprise, Libby seemed just as transfixed by Chloe's breasts as she had been with my cock just moments ago. Chloe, thinking that Libby was finally averting her eyes from me, was having none of it. "Look at him." When Libby didn't respond, she gently grasped her by the chin and turned her head directly towards my manhood. "He's hard for you, Libby. You must have heard him saying your name." Libby swallowed visibly. Suddenly she seemed to register that her panties were tying me down and that another pair was on the pillow. She began to shake her head in a childish gesture of denial. Chloe took her chin again and stopped her. Then she tugged down until my sister had no choice but to kneel at the end of the bed. I strained my head up to see that they were both now at eye level with my cock. "I've never seen him this hard before." Chloe spoke slowly, as though explaining something to a small child. "That means he really, really, wants to fuck you." Libby gasped sharply at this, but still said nothing. She just kept watching as another droplet leaked out of me. "That's precum Libby. His cock is ready to fuck." Libby shook her head yet again, indicating no, but still watching me. "You think it's too naughty." Although she had been delighted by my sister's presence so far, Chloe now sounded disappointed. Then Chloe said the words that sent a shiver down my spine. "You should at least touch him though. Be a good girl and finish what you've started." I couldn't believe it, but as though in a dream I beheld Libby reaching out with a quivering hand. I bit my lip and braced for impact. Libby touched me and I was immediately right back at the brink of cumming. Her fingertips, ending in perfectly manicured French-cut fingernails, brushed timidly over my engorged organ, swirling the saliva. I was aware of every point of contact, revelling in the delicious friction. "That's it." Chloe cooed softly, encouraging her. "Now stroke." Libby clearly had little idea of what to do, but it was still amazing. "Hold it firmer." My girlfriend angled my cock down towards them and guided the other girl's hands to wrap properly around it. She didn't let go until she was sure that Libby would stay. I was certain that one pump would do it, but I survived, valiantly trying to think of anything that would prevent me cumming under my sister's inexperienced touch. While one part of me wanted this more than anything in the world, the other part was screaming out against the incest taboo coming to life before my very eyes. My baby sister is rubbing my cock to pleasure me. Libby is masturbating me to make me cum. She leant over in fascination and I had no time to warn her. The first shot hit her right in the face. She jumped back in surprise, letting go of my cock as it continued to spray my bliss out into the open. A supernova burned its way through me, big enough to envelop the galaxy. I threw my head back into the pillows mindlessly and emptied everything my balls had been saving. I blearily saw that the thick white fluid was strewn across Libby's top lip and left cheek and was beginning to run. She was clearly not expecting it, and looked bewildered. Her eyes were wide as she inspected the evidence of my pleasure running between her fingertip and face. She spoke for the first time since coming in. Her tone was one of reverence and awe, as though she couldn't believe it was true. "You actually want me." *
