"Screw you," Mike grunted back, breathing through his teeth. Mike relaxed his stomach muscles before performing a barrel roll, forcing Dave off his back; he then proceeded to force Dave's arm far up his back. "Fuck off Mike; you're going to sprain my arm!" Dave bellowed. "Yield?" Mike asked. "Fine!" Dave relented; Mike released his arm and stepped away. "Shit Dave, maybe someday you'll prove to everyone that you're not a complete weakling," Mike teased, "I'm absolutely thrashing you." "Shut up Mike," Dave shot back, "I almost had you for a second, and anyway I beat you just as much as you beat me!" "So far as I remember," Mike taunted, "the running total is 18 wins to 24!" "Yeah, in my favour dumbass!" Mike's hands shot up in admission and a giant shit-eating grin split his face in half. "I was hoping you wouldn't pick up on that," he said as Dave pulled him to his feet and they walked through the gym towards the door. "So are you giving me a lift home or what?" Mike asked his friend. "I dunno. Are you going to pay for the petrol money then?" Dave replied coolly "Why is that?" Mike asked, "Are we recalling debts today then? Because I seem to remember you owing me a considerable deal from last weekend." "Fine, you win, you get your lift home," Dave said, realising that paying back his debt would set him back money that he desperately needed for car upkeep. "Is that piece of shit actually running today then?" Mike asked. "If you don't like the way it runs you can walk home, it'll save me the drive," teased Dave, knowing the prospect of walking would shut Mike up, "OK, you win I'm sorry," Mike relented. *** Dave dropped his bag on the floor in the kitchen, before making his way to the fridge and grabbing a bottle of water, which he promptly gulped down. He went upstairs to his room, grabbed a towel and opened the bathroom door, freezing in the doorway. Dave's sister stood on full display in the shower; water cascaded down her luscious, full body. He gaped at his sister whilst water from the shower head ran from her copper hair, forming rivulets that ran between her pert breasts before sliding down to her smoothly shaved mound. Dave blinked and shook his head, quickly closing the door to the toilet. "What the hell am I doing?" he thought to himself as filthy thoughts flashed through his mind concerning his sister. He shook his head again to dispel the impure thoughts. Dawn was a beautiful girl, with flowing red hair and a figure that had filled out very nicely over the years. 'But she's my sister!' he thought aloud. "Everything alright up there Dave?" his mother called up the stairs; Dave's heart pounded in his chest. "I'm fine mum, just stubbed my toe," he called back down, berating himself for the slip-up. He flopped down onto his bed, all thoughts of showering lost as he tossed around, feeling too restless to sleep. *** 'My God that was hot!' Dawn thought to herself as she dried herself off. Her brother had walked in on her in the shower, and she hadn't done a thing about it. Dawn lay down on her bed, fiddling restlessly before climbing up and looking through the hole conveniently positioned between her and Dave's room. The hole was positioned in Dave's cupboard which, fortunately for Dawn, he never closed. Dawn positioned herself in front of the hole and was disappointed to discover her brother was already simply lying on his bed. 'Oh well,' she thought to herself, as she threw herself back onto the bed, 'guess tonight I have to go without inspiration.' Dawn climbed under the covers and after taking a couple of deep breaths buried two fingers inside herself. She steadily pumped until she was panting heavily, reminiscing on her brother's expression as he walked in on her. *** Dave realised that he hadn't eaten since lunch, so he rolled out of bed and began his way downstairs. After grabbing a leftover chicken sandwich and some apples he climbed back up the stairs to his room. As he was about to sit down a peculiar sound came from the other side of his wall. He climbed into his cupboard and placed his ear against the wall. He heard his sister breathing heavily and moaning through the wall. 'Probably having a nightmare,' he thought to himself. He was about to go back to his desk until he noticed a spot of light coming through his wall. As he looked closer he realised it was a hole in the wall about the size of a ten pence piece. 'What the hell?' he muttered as he placed one eye against the hole. Dave gasped as he saw what was on the other side. Dawn was lying on her bed with her hand stuffed down the front of her pyjama bottoms, the sheets kicked down to the base of her bed. Dawn began to pant more heavily and a sheen of sweat was apparent across her face. Dave was about to look away when he heard her gasp. His twin sister's legs spasmed and she let out a soft gasp. After a couple of minutes Dave saw his sister pull her hand out, now soaking wet, and wipe it on her sheets. She then proceeded to pull the duvets back up around her and fall asleep, tired after the day's escapades. Dave pulled back from the hole, his legs shaky; he climbed into bed, his food left untouched on the side. 'Christ I must be completely sick!' he thought to himself as he drifted off to sleep, haunted by ever more shocking dreams concerning his sister. *** "Jesus Dave, why aren't you up yet?" his mother, Stacy, demanded 8 hours later, "You have to be ready in 10 minutes!" Dave's eyes shot open. 'Shit,' he groaned and ran past his mother and into the bathroom, showering as fast as he could, accidentally rubbing shampoo into his eyes and trying to brush his teeth at the same time. He towelled off quickly and ran downstairs, pulling his shirt on as he went and shoving his tie into his pocket. "Hurry up Dave, you need to get some lunch," his mum insisted. "No time," he grunted back and ran out to the car, his mother slowly following him. "You know I worry about you sometimes," his mum said to him in the car, "You're so bone idle it's a wonder you can function at all." Dave pointedly ignored her, and sat in stony silence. "You kept me waiting, Dave," his sister teased, "late night?" Dave mumbled something in reply to his sister, avoiding eye contact. "Wow, not really a 'morning person' are you Dave?" she giggled. *** Dave stumbled into his Biology class a mere 5 minutes late, drawing a glare from the teacher. He picked his way through the class next to Mike. "Late night?" Mike asked, grinning at his friend. "Yeah, your sister says hi," Dave replied smoothly. Mike rolled his eyes. "You really need to come up with some new material Dave," he groaned. "Hey, at least I didn't say your mum!" Dave replied. "Whatever," his friend said. "Oh I forgot to tell you, after you dropped me off yesterday I had a little accident." He grinned sheepishly. "Oh yeah? What happened?" "Fell down the stairs," Mike told Dave, "Sprained my leg real good." "Pfft! Dumbass!" he replied, and then suddenly it dawned on him. "Wait!" "Yep," his friend replied, "can't do judo anymore." "You bastard!" Dave said, angry at his friend for his clumsiness. "I know, right." Mike didn't seem at all too upset. "Guess that means you get a new partner, maybe the teacher will be nice and put you with Ellie Cook." Dave shuddered as Ellie's face flashed up in his mind. "Don't even joke about that Mike, it's not funny," he said. Mike grew serious. "Yeah, sorry that was below the belt, but who knows, maybe you'll get lucky." At that point the teacher made a point of stopping mid-sentence to glare at the two; they promptly cut their conversation short. After the lesson was over and the bell rang they walked out of the classroom. "What have you got today?" Mike asked. "Full day." "Bad luck, I've got nothing but frees from now," Mike taunted. "You know I hate you, right?" Dave said. "Yep," his friend replied, "have fun at judo tonight." *** Dave's day went by uneventfully; he spent the majority of his time thinking about what he was going to do for a partner now that Mike had dropped out. He hoped to God that the instructor would partner him with someone who was at least reasonably skilled, or else he wouldn't be able to keep his skill level up for the upcoming tournament. Whilst deep in thought about his predicament he missed several important formulae which his teacher was spewing out. 'Oh well,' Dave thought to himself 'I guess I'll have to catch up later'. As Dave's mother was still at work and he didn't have any cash on him he resigned himself to walking home. 'At least it's a nice day,' he mused. At four miles, the walk home was a huge hassle during the winter months; however they were fortunately enjoying the last weeks of a long, sultry summer. Dave enjoyed the walk home, and took pains to do it as frequently as he could, in order to try and keep his cardiac fitness up; whilst he was well toned and reasonably strong, his endurance was very poor, and he couldn't hold up in any form of running. As he neared halfway he heard a car horn honk behind him. He turned to see a red sports convertible pull up beside him; his sister was in the passenger seat next to one of her various friends, whose names Dave always struggled to remember. "Hey bro, how's it going?" Dawn asked as she rolled down the window. "Hey Dave!" His sister's friend's eyes flashed at him. "Walking home today?" "Yeah," Dave sighed exaggeratedly, "It's a tough old life." He hoped he might be able to catch a lift home. "Why don't you come with us Dave?" his sister's friend asked. "I'm on my way there now, I'm sleeping over." Dawn bent over and whispered something in her ear, causing her to giggle softly. Dave, suddenly remembering her name replied, "I'd love a lift, Jo; thanks for offering." "Hop in then," she said, flashing Dave a dazzling smile. Dave clambered into the back seat of her car with no small amount of fuss, grateful for a reason to cut his walk short. "So how come you don't drive to school Dave? You've got a car haven't you?" Jo asked him. "Well, I can't really afford the parking costs; besides I'm too worried it'll break down on me on the way home," Dave said, grinning in embarrassment. "What do you drive?" Jo asked. "A Punto," Dave said, further embarrassed. "How old is it?" "'95," Dave admitted, his face now beginning to turn red. "Wow," Jo said, a grin stretching across her face, "vintage!" Dave shrunk back in his seat and tried to steer the conversation away to less embarrassing topics. He loathed the embarrassment that his sister's friend was causing him, whilst at the same time noticing that she was very pleasant looking, if a little too outgoing to match Dave's shy persona. When they arrived at Dave's house he once again thanked Jo for the lift, the dazzling girl flashing him yet another smile. He then made his way up to his bedroom to try and get on with some maths that was quickly piling up. *** "What you doing?" Dawn asked. "Maths," Dave replied, spinning in his chair to face his twin sister. "What kind of maths?" Jo asked. "Calculus." "What?" "Integration." "Whassat?" "It's all numbers, I wouldn't worry about it, it's a little dull," Dave said, trying to move conversation away from his homework, concerned he would seem like more of a loser than he already did. "Anything wrong," he quickly asked. "Why should anything be wrong for me to want to see my brother?" his sister asked a little too quickly. "Uh, I dunno, I didn't mean it in a bad way sis." Dave was becoming ever more conscious of Jo staring at him, he gazed over at her and she quickly averted her eyes, staring towards the window. "Jo just wanted to come and check you out big bro," Dawn said. Jo's face quickly turned red with embarrassment; she hurriedly tried to find a diversion. "Why did you say big brother? I thought you were twins," she asked Dawn, hoping for the topic to change. "Well we are, but we don't have the same birthday; I've got a whole 20 minutes over Dawn," Dave answered for his sister. "I was born at 11:55 and she was born at 12:15 the next day." "Wow," Jo said unenthusiastically, "that's really interesting." Now it was Dave's turn to become red; he decided to cut his losses and get the girls out of his room before he embarrassed himself further. He thanked them for dropping into his room, but said that he felt tired due to his work load and wanted to go to bed. "But it's only 9:15," Jo said, glancing at Dave's clock. "Uh... yeah but I've got, uh, an early start tomorrow," he said, quickly coming up with a poor excuse. "Yeah, sure Dave," his sister teased, winking at him, "You seem a little flustered, you probably don't know what to do with two beautiful girls in your bedroom." Dave tried to look innocent, but the expression on his face quickly proved the truth in his sister's words. "Come on Jo, let's go," Dawn said, turning to her friend. "We should leave my brother to his thoughts." They both giggled and sauntered out of Dave's room. Dave turned back to his desk, but he quickly realised he was feeling far too horny to do any work; after 20 minutes without finishing a single question he decided to give in, flopping down onto his bed. He glanced guiltily at the hole in his cupboard wall, but figured his sister probably knew nothing about it; he resigned himself to fix it at a later date. Too distracted to give it any further thought Dave undid his trousers and slipped out his cock, quickly stroking himself towards an orgasm. *** Dawn squealed in delight, pulling back from the hole in her wall and motioning for her friend to come over. "I told you he'd be at it in a while; he hasn't beaten one off in days, and it was only a matter of time." "How exactly would you know your own brother's masturbation pattern Dawn?" Jo asked. Dawn seemed very flustered. "Err... I can just tell because he's really pent up today, and he usually gets stressed after uh..." "Okay, okay I get it," Jo said, but she seemed dissatisfied with her friend's answer. She climbed into the closet and placed her eye against the wall, gasping when she saw her best friend's brother furiously masturbating on his bed. She realised that it was quickly getting exciting, as she felt a damp patch begin to appear between her legs and heat radiated from her pussy. "My god Dawn, your brother is really hot!" she gasped. "I really wouldn't know about that," Dawn replied casually, secretly wishing that she could be the one peeking through the hole. *** Thoughts of his sister's best friend flashing through his head, Dave desperately tried to picture something else as he drove himself closer and closer towards the edge. Finally he gave up and began imagining having full blown intercourse with her, quickly increasing the pace of his strokes. As he began to cum he guiltily glanced at the hole as wave after wave of semen spurted onto his chest. He stepped towards his desk, seeing a flurry of movement on the other side of the hole. "Shit!" he thought, "here I was fantasizing about her and Jo was watching all along." He collapsed back onto his bed and lay awake for hours before finally succumbing to sleep. *** Dave parked his car and made his way into the gym for Judo practice, dreading what was going to pass. He nervously walked inside and made his way to the instructor. "So?" Dave said tentatively. "So what?" the trainer, Dan, said back. "I guess I need a new partner now." "Oh yeah," Dan said, having obviously forgotten. "I was thinking I'd put you with a new one who joined yesterday." Dave groaned inwardly; it looked like he wasn't going to get any of the advanced practice he needed. "I'll tell her to make her way over to you. Just go to your mat and do some stretches, then show her a couple of basic holds," Dan said, "I'm sorry I can't put you with someone more experienced, but they say the best form of learning is teaching." Dave told his trainer that it was alright and made his way across the gym, beginning some light stretches. He was bent over holding his ankles when a tentative voice shyly said, "Hi, I'm Amy, I think I'm supposed to be going with you?" Dave glanced up and his breath caught in his throat. Standing before him was by far the most ravishingly beautiful girl he had ever seen, with long, wavy blond hair and tantalising green eyes; she stood at around 5'7'' with a curvy figure, which was very poorly concealed by the robe she wore. Dave quickly realised that he had been staring at this girl for 10 seconds and quickly stammered, "Umm... h-hello, I'm Dave." Amy giggled at Dave's obvious discomfort. "Hi Dave, nice to meet you!" she said with seemingly genuine enthusiasm, "sorry you got bunked with the new girl." "Its fine, I don't mind at all," Dave said a little too quickly. "Yeah, I bet you don't!" Amy said, blushing deeply as she realised what she had just said. Dave was a little taken aback by what she had said, and was even more surprised to see this beautiful girl blushing deeply. He quickly jumped to his feet. "So I suppose I should show you a couple of moves," he said, berating himself for his lack of charisma. "That'd be nice," Amy replied. Dave proceeded to show her a couple of basic chokes and grabs before moving on to holds, realising it suddenly felt awfully hot in the gymnasium. He demonstrated how to begin the hold to Amy and she began to carry them out with ease, obviously a natural. "And now you have to lift your leg over and um... straddle my stomach," Dave said nervously. Amy grinned and quickly complied carrying her leg over and sitting near the base of Dave's torso, whilst leaning towards him until their faces touched and weaving her hands behind his neck in a hold. "And this is called uh... Jun..." Dave stammered as he felt her body heat tantalizingly close to his pelvis, quickly forgetting the name of the hold. "Uh... I forget," he said a little lamely, gritting his teeth as he began to feel blood suffuse down towards his groin. The last thing he wanted was an erection in the middle of a crowded gym. Amy smirked at his obvious discomfort and slid off of him, taking care to rub against his groin as she dismounted him. "It's okay Dave, I don't really need to know all the names yet I suppose." She gave him a winning smile. "I can understand why you're flustered, I'm finding it a little warm in here myself." Dave merely gawked at her, whilst in his mind he was screaming, 'Just say something! You could ask her out!' whilst a large part of him screamed back, 'Look at her, there's no way she'd say yes to you!' He climbed up and glanced at her nervously. "Everything all right?" she asked him innocently. "Uh yeah," he managed to say, "I was just wondering if uh..." "What's that?" Amy said quickly, her eyes lighting up and a huge smile growing on her face. "If you err... wanted to do some extra practice outside of the gym?" Dave said and quickly groaned, "Sorry that sounded raunchy." Amy giggled. "Are you asking me out Dave?" she asked, looking unbelievably sweet. "Uh, I don't know, why? Would you like to go for dinner or a film or something?" he asked nervously. Amy's whole face lit up. "I'd love to! When are you free?" she asked, catching Dave off guard. "Well um, how about this Friday?" he asked tentatively. "I'll see you then!" Amy said, giving him a quick hug and picking her way back across the gym towards the exit. Impurity Ch. 02 ###notes#### I got a number of comments on chapter 1 saying that the description was wrong and that Dave didn't develop any feelings towards Dawn. My apologies. The relationship between Dawn and Dave isn't completely tangible sexually, that doesn't come until a bit later on. For those of you who read chapter one and were disappointed by the lack of action should probably skip straight to chapter 4 (when it's been uploaded that is.)Whilst there is some action in this chapter, there are no outright sex scenes involving Dave. I'd appreciate any feedback that you might have and hope you enjoy the story. Finally, thanks to Zebra for doing my edits. ###notes### Dave stepped out of the shower and dried his hair, trying to select some clothes for his date. He wasn't sure how to dress or behave on a first date, so he went for a smart casual look, picking out dark jeans and a black shirt with no tie. He applied a liberal squirting of aftershave and checked himself in the mirror, combing his hands through his still damp hair and making his way towards the door. He climbed into his Punto, fervently wishing the next payday would come sooner so that he could afford the new car he had been pining after, a Saab turbo convertible, 1999. He clambered into his car before making his way across to Amy's house, a 5 or so minute drive. As Dave walked up the path to her generously sized house the front door slowly opened and his date walked out before closing the door and daintily making her way down the path. Dave's mind reeled as he saw Amy stroll down the path, her wavy blond hair left to tumble down around her shoulder, and wearing a light summer dress that came to just above her knees, leaving the rest of her well tanned legs on display. As she glided down the path she flashed Dave a glimmering smile. "Hi Dave!" she said, giving him a light peck on the cheek, leaving him struggling for words, "you're right on time." Dave struggled to make a reply, all coherent thought erased by the presence of this astonishing beauty. "Uh... Hi Amy, it's really nice to see you," he stammered back. "Shall we go then; where is it you're taking me?" she asked, cocking her head to one side and staring at him inquisitively. "It's a restaurant over on the east side, an Italian." Dave was relieved he had managed to reply without stumbling over a single word, and tried to calm down a little. "Ooh! I love Italian!" Amy replied, practically leaping for joy. They both clambered into Dave's car. He was concerned at first she would comment on its condition, but she seemed content and he decided to avoid bringing it up. After driving for several minutes Dave realised that they had been in silence for quite a while, so he moistened his lips before stammering out, "You look really beautiful." Amy shifted in her seat so that she could give her date a good, hard stare, before blushing and thanking him for the compliment. "I really like your car," she said. "You don't have to say that you know," Dave said, getting the feeling that this was not her true impression of his rust-bucket. "I know it's bad, but I'm getting a new car on Wednesday." "Ooh! What kind?" Amy asked, glad that the conversation had picked up. "It's a Saab turbo, the '99 convertible," Dave replied, fervently hoping that this line of conversation would last until they reached the restaurant. "How are you paying for it?" Amy asked, genuinely interested as far as Dave could tell. "I've been saving up since a month after I got this car; my dad's going to pay for a third." Dave pulled into the car park of the restaurant; he got out of his side, walked around to the passenger side, opened the car door and offered his hand to Amy who took hold of it and lifted herself out of the car, giggling at Dave's formality. "I'm glad you're not really used to this dating thing either," she said to Dave, promptly realising that she had unintentionally insulted her date and turning a rosy pink with embarrassment, throwing Dave an apologetic glance. Dave looked at her appraisingly. "You're not used to dating?" he asked, confused. "Why, should I be?" Amy replied, without comprehension. Dave turned his eyes away from Amy, once again embarrassed. "I just figured that guys probably ask you out a lot, seeing as you're so stunning," he said truthfully, once again glancing up at Amy to see a soft smile cross her radiant face. She gave him a quick hug, squeezing Dave against her. "Thank you!" she said, beaming, "It's because I used to go to an all girls boarding school, but I dropped out the second I turned 18, so that I could join college for my last year; it was so boring there," she explained. A waiter came and seated both Dave and Amy in a corner of the restaurant, which was romantically lit with dozens of candles; he gave Dave a grin and asked if either of them would like a drink. Amy ordered a red wine; Dave decided to only have a soft drink in order that he could drive back home, so he ordered himself a lemonade. The waiter left and quickly came back with the drinks' orders, asking what the couple would like to eat. They asked for olives to start and for him to leave the menus. After the olives came Amy settled down onto her elbows and stared at Dave; he began to shift in his seat uncomfortably. "So," he said. "So," Amy replied. "Where did you go to boarding school?" Dave asked. Amy delicately speared an olive with a toothpick. "It was some tip up in Norfolk," she replied, waving around her olive before placing it between her immaculate lips and softly chewing it. Dave began to feel slightly outclassed and made mention of this fact to Amy. She giggled politely, before placing her hand on top of Dave's on the centre of the small table. "It wasn't all that terrible, but spending every waking moment with members of the same sex starts to warp your mind a little," she replied. Before Dave could think on what she had just said she cut across his thoughts with her question, "So how long have you been doing judo?" "About 10 years," Dave replied, "since I was 8." "Wow, you must be pretty good," Amy remarked. "Well I suppose so," Dave said, attempting to be modest, "I'm at the top of the score list in our group; but I suppose Mike and I are pretty much equally matched." "Mike?" "He was my training partner before you," Dave explained, "but he sprained his leg last week, so I got partnered with you." "That's pretty bad luck isn't it?" Amy asked him. "Why's that?" Amy gave him a blinding smile. "Because that means you had to get partnered with me," she said plainly. Dave was dumbfounded. "Why is that bad luck, I'm on a date with you now aren't I?" Amy bit her lower lip. "Yeah, but you do realise that I'm gonna try my hardest to corrupt you, right?" Dave felt the blood rush towards his groin, causing a tent in his trousers that was becoming more and more noticeable by the minute. Not knowing what to say in reply, a welcome distraction came when the waiter returned with their main courses. They passed the rest of the meal talking about inconsequential things. Amy delicately swirled her spaghetti around her fork whilst Dave attempted in vain to look remotely sophisticated; he assumed that Amy's boarding school had been big on etiquette. After they had finished they stayed for another drink and then Dave paid the bill before leading Amy out of the restaurant. "Thank you for that meal, it was delicious." To illustrate her point Amy ran her tongue across her painted red lips; Dave had to suppress a moan at the sight. She slid her arm through Dave's as they walked towards the car. They climbed in and Dave began to drive back across town. "We're not going home already are we?" Amy asked Dave, disappointed that the evening was already over. "Well, it's only half-nine, what else would you like to do?" Dave asked, having no idea what to do on a first date. "Well, you've lived here longer than I have; where is there a nice spot for a stroll?" Amy asked. "I know where we can go," Dave said, not slowing down as he passed Amy's house. They drove for another few minutes before stopping in a forestry car park and climbing out of the car. Dave noticed that there had been an unexpected drop in temperature, so he grabbed his coat out of the back seat of the car, passing it to Amy. "Wear this, you're not properly dressed for this weather," he said, seeing Amy bite her lower lip once again and stare into his eyes; she walked towards him and grabbed his hand, guiding it across her shoulder and began to walk. Dave left his arm draped across Amy's shoulder, escorting her on a walk around the forest to which he had driven them. Amy said nothing, seeming content to walk in silence. Dave noticed that she continued to knead her lower lip between her perfectly formed teeth, and was beginning to breathe slightly more heavily. After they had been walking for a few minutes Dave was about to suggest that they turn back when Amy turned to face him and forced him backwards until his back was pressed against the trunk of a broad oak tree. She moved herself closer against him. "I had a really nice time at dinner," she breathed; her lip began to appear swollen due to the constant attention it had been receiving. "Thanks," Dave replied, feeling slightly apprehensive, "I had a great time too." Amy moved ever closer into him before rising up onto her toes and giving Dave a quick peck on the lips. Dave was beginning to feel disappointed as she threw her arms around his neck, forcing his head down towards her own. Dave felt a tingling sensation running through his body in pulses, originating at his lips. As Amy continued to knead his lips between her own he began to feel lightheaded, realising he had not breathed in for quite a while. By the expression on Amy's face she was also beginning to run out of air, but was equally reluctant to break the kiss; finally the need to breathe won over, and Amy pulled away, though not before grabbing Dave's lower lip between her own for a moment. They both desperately tried to draw air in, feeling woozy from the lack of oxygen. Whilst on the drive home Dave and Amy continued their small talk, Amy's hand wandered towards Dave's lap and began to stroke him through his trousers. Dave tried to concentrate on the road while Amy's efforts became more and more pronounced. Dave's concentration dropped for a moment and he found himself drifting into the opposite lane. Dave quickly realigned himself and took Amy's hand out of his lap, instead incasing it in his own. *** Dave threw his keys on the counter, making his way up the stairs and into his bedroom; he considered dropping in to say hello to Dawn, but decided to go straight to bed. As he flopped down onto his bed he heard a gasp, the sound emanating from his cupboard. As he neared the hole in his wall the gasps grew in volume. Throwing caution to the wind he placed his eye against the hole and drew in a sharp breath, surprised at what he saw. He saw Jo seize Dawn by her shirt and force her backwards onto her bed, before climbing on top of her and clasping her head between her hands. Their lips met and contact was held for several minutes before they broke apart. Jo slid down Dawn's body, reaching for the hem of her nightshirt and ripping it upwards. As Dawn's breasts were exposed to the cold air she gasped with pleasure, whilst attempting to do the same to Jo. Jo smirked at Dawn's failed attempt to undress her. She sat up and dragged her shirt above her head before throwing it to the floor. Jo then continued to slide down Dawn's body, jerking her red underwear to the side, and slowly slipping a finger between her juicy lips; Dawn once again gasped with pleasure. As Jo began to pump her finger in and out with increasing speed Dawn's gasps and moans increased in volume. Back on the other side of the wall Dave could almost hear the sounds of wet sloshing as his sister was pushed closer and closer to climax. He gasped as he saw Jo pull his twin's panties down to her ankles, and lean in closer; she began to swirl her tongue around Dawn's lips, making ever smaller circles around her clit; she finally slipped her tongue inside and Dave heard Dawn's moans loud and clear. A sheen of sweat began to appear across her forehead and her breathing began to increase to a rapid rate. Dave could see Dawn's breasts rising and falling at a rapid speed, and as her breathing became more and more laboured she interwove her fingers in Jo's hair, forcing her face closer and closer into herself; as her moans intensified Jo increased her attack on her best friend. Eventually Dawn collapsed on her pillow, pulling Jo across her, and locking their lips in a deep kiss, running her tongue across Jo's teeth and forcing her own tongue into her mouth. Dave staggered back from the hole, before collapsing onto his bed, completely stunned by the activity being performed before his eyes. The revelation that his sister was a lesbian came as a great shock to him. He was struggling to suppress the images that flashed across his mind, and he began to feel tightness in his boxers. He gritted his teeth and tried to think of something more innocent. For several minutes he battled against his perverted imagination, before finally giving up and climbing underneath his duvet, slipping his boxers down his legs and submitting himself to a night of debauchery, constantly thinking of the sight observed through the hole to his sister's bedroom. *** Dave awoke the next day feeling distinctly sticky, his mouth felt fuzzy and there was a bad taste present; he glanced at his clock and saw it was past 11; Dave groaned and rolled out of bed, slowly making his way downstairs. "Morning," his mum said. He grunted back in reply, struggling to keep his eyes open and pouring out a bowl of cereal. "You were back pretty late last night," Louise said, "Where was it you went?" "Just out with Mike," Dave replied, not wanting to let his mum know about Amy. "We went bowling." Dave's mum shrugged, obviously not satisfied with Dave's story, but not wanting to pry. She grabbed Dave's empty bowl and made her way to the sink. "So what are you going to do today?" she asked her son. "Nothing much," he said, "Maybe a bit of revision; what's Dawn up to?" "She's already gone out with Jo. I think she should be back in a couple of hours," Louise replied. "Cool, I think I'll start on some work then." Dave made his way upstairs with every intention of working, but somehow wound up on one of his bookmarked pornography sites; he played music and turned the volume down on the video, before spending the next hour doing very little work. The loud music drowned out the sound of his sister coming up the stairs, having returned from shopping; Dave had only a few seconds notice as she knocked on the door, quickly closing the browser window and spinning his chair around to face the door. "Hello?" he called out; Dawn opened his door and dropped down onto his bed. "Hiya Dave," she said in greeting, "What are you doing?" Dave began to feel embarrassed and tried to keep his face from flushing. "I was planning on doing some revision, but I ended up just browsing," he replied. Dawn seemed happy with this and lay back against the wall. "Ugh! I hate shopping!" she said in exasperation. "Jo wanted to have a look in every single shop, and I just wanted to leave." Dave grinned at his sister; he felt highly amused at her discomfort. However his smile quickly faded when he remembered the sight he saw last night. He tried unsuccessfully to clear his head, and it took several seconds to compose himself. When he finally regained his composure he saw Dawn staring at him inquisitively. "Something wrong bro?" she asked, concern in her eyes. "No, I'm fine." Dave rubbed his eyes. "Just a bit of a headache, all that work got to me." Dawn giggled and twitched her fingers to emphasize her point. "Yeah 'work'," she said exaggeratedly, before smirking at him. Dave gave his twin a withering look, before they both got up and made their way downstairs and made some lunch. The whole time Dave's mind kept wandering towards what he had seen his sister do; as they made his way up to the room he decided that he wouldn't be able to resist temptation and that he should inform Dawn that he knew about the hole in the wall. "Hey Dawn, I noticed something last night," he said casually. Dawn's reply was equally offhand. "What's that Dave?" "I saw a light coming out of my cupboard, and I found a hole in the wall," he said, surprised by her lack of surprise. "It's positioned right between your room and mine, and there's a really good view of your room." "Oh yeah? Did you see anything interesting?" Dave gulped and tried to remain calm. "Not really, just you and Jo asleep," he said, praying that Dawn would accept his story; she nodded, seemingly happy. "I'll look into it." *** Dave slept restlessly that night, rolling from side to side in his bed. He finally gave up and made his way to his cupboard, from which a beam of light pierced his room. As he placed his face near the hole he saw a flurry of movement on the other side as Dawn lay back on her bed and kicked the covers aside. Dave couldn't help but watch as she began to furiously force herself to an orgasm; Dave watched for a few moments before tearing himself away from the hole and flopping onto his bed, his mind reeling. 'She can't have forgotten!' he thought to himself, 'I told her about the hole not three hours ago.' Dave was shocked at the realisation that she had purposefully put on a show for him. It was the only explanation as to why she had positioned herself in front of the hole so that he could see every little detail. Dave lay awake all night as he considered what to do about his sister's advances. *** Dave once again woke up feeling distinctly sticky; he had the same bad taste in his mouth, which felt like it was full of cotton; he wondered if he was coming down with something. He got up and made his way downstairs. As he came into the kitchen he saw that his mother had already left and his sister was the only one home. Dave groaned inwardly as he noticed what his sister was wearing - a T-shirt, which was obviously several sizes too small, and nothing underneath except for a skimpy pair of bikini bottoms. "Hi Dawn," he said, trying to strike up a conversation with his sister as he put some bread in the toaster, trying not to think about what he had repeatedly seen his sister do. "Hiya Dave!" his twin sister replied brightly, completely unfazed by her lack of clothing. Dave had to make several attempts before he could strike up a conversation, distracted as he was by Dawn's indecency. "So what are you going to do today?" he finally managed to say. She glanced up at him innocently. "Oh nothing much, just a lazy Sunday really, thought I might watch a bit of TV. D'you want to join me?" Dawn continued to gaze at Dave; he nodded in affirmation and followed her into the front room with his toast. Dawn put on 'Family Guy' and glanced across at her brother. "Is something wrong?" she asked, genuinely concerned about her brother's unusual demeanour. "No, everything's fine." Dave shifted his gaze towards the television. "Just a bit tired, that's all." However Dave knew that everything was not fine as he began to feel a stirring in his jeans; as he tried to repress images of his sister, with little success, his erection began to grow even larger. He could see his sister eyeing it. "Are you sure Dave?" she asked, a glint in her eye, "You look a little uncomfortable." Dave raised himself from the sofa and made his way back towards his room, muttering something about homework to his sister and trying to hide his swollen cock from her eyes. Impurity Ch. 03 ###notes### I got much better feedback for chapter 2 than I did for chapter 1, hopefully people will enjoy this even more, since it contains the first 'real' sex scene so far. Once again, thanks to Zebra for the edit, and I'd really appreciate some feedback. ###notes### Dave closed the door behind him. He had just got back from dropping Amy home, and Dawn was already waiting for him in the kitchen, arms crossed and with a giant smirk on her face. "Hello Dave," she said, her idiotic grin still plastered across her face. Dave sat down on the seat next to her and stared back at her defiantly. "Hello Dawn." "So Amy seems nice then," Dawn said, staring up at him. "Quite pretty..." "Yeah, so?" Dawn held her hands up innocently. "I'm just saying she's pretty stunning, especially for an ugly git like you." Dave turned his face into a mock-angry mask. "Who are you calling ugly, sis?" he rebuked, "You're starting to get a little podgy, I think you should start hitting the gym a bit more." Dawn snorted. "Me? You're getting pretty good at throwing your weight around!" "Yeah, but mine's muscle weight!" Dawn began to giggle, and eventually was roaring with laughter. "All right handsome," she gasped between breaths, "You win!" Dave grinned, feeling delighted at the small victory and made his way upstairs. As he sat down it occurred to him that Dawn had probably been watching through the hole; he decided to go and talk to her about it once again. Dawn was already in her room when he knocked on the door; he heard a flurry of movement and the door swung open. Dawn was looking a little flushed. Dave grimaced with embarrassment. "Are you busy?" he asked, "I could come back later if you'd like." "No, no!" Dawn said, stepping aside to allow Dave entrance, "I'm not doing anything special." Dave somehow didn't believe his twin sister as a distinct smell pervaded the air in her room. "I came to ask you about that hole in the wall," Dave said, deciding to cut straight to his point. "What about it bro?" Dawn asked, biting her lower lip and staring up at him innocently. Dave was not swayed. "Don't give me that look," he said, "You may fool mum and dad, but I'm not that easy." Dawn continued to stare up at him, trying her hardest to look as innocent as humanly possible. "What about the hole?" Dave gritted his teeth. "What did I just say?" he said angrily, "Have you been spying on me through the hole?" "Only a little." Dawn continued to chew her lip. "Did you watch me and Amy through the hole just now?" Dawn shook her head fiercely, but the expression on her face told Dave everything he needed to know. "You bitch!" he cried. "Me?" Dawn exclaimed, "You were watching me and Jo through the hole as well!" Dave had no idea how to reply to this, and struggled to find words for a rebuttal, stammering and stuttering. Dawn's face lit in triumph as she rounded on him. "That's right!" she said, her voice beginning to rise in volume. "I saw you watching me with Jo! So don't go throwing around wild accusations when you're a filthy pervert!" Dave's anger once again rose like bile. "You were the one who was putting on a show on purpose, you're a slut!" he cried, feeling regret the second the words left his lips. Dawn's face fell and she began to turn away. Dave quickly put his arm around her shoulder and murmured to her. "I'm sorry Dawn, I didn't mean that." Dawn tried to prise his arm from around her shoulder; Dave forced her to face him. "The whole thing was my fault, I found out about the hole first; I should have boarded it up straight away and I guess I'm just messed up for watching you and Jo." Dave hung his head and walked out of the room, lying down on his bed before falling into a deep sleep. *** Dave's alarm wailed loudly in the morning. He groaned and hit the snooze button, he was glad to notice that he didn't feel sticky that morning. Rolling over he saw it was 7.15 and groaned once more before climbing out of bed. Outside it was raining torrentially, lightning splitting the sky in jagged lines. He grabbed a towel and jumped into the shower, quickly washing himself before climbing out and towelling off. As he stepped out in his towel he nudged into Dawn who was waiting outside in her towel. "Morning," he said. Dawn mumbled something in reply and closed the bathroom door. Dave shrugged and made his way down the stairs and into the kitchen. As he poured his cereal he noticed that his mum's car was already gone; he looked around the kitchen and saw a note sitting on the table. Dave picked up the letter and noticed his mother's handwriting. Hi Dave and Dawn. I was called away on some urgent business, so I'll be away until next Monday; there's plenty of food for the week and Dad will be back on Friday. You can invite some friends round if you like, but no parties! Dave, you have to give Dawn a lift into school; I'll phone you to check up in a couple of days. Have a nice week. Mum Dave tossed the letter back on the table for Dawn to read and went back to his cereal, grabbing a spoon out of the drawer. Dawn came down after a couple of minutes, her hair still damp from the shower, and picked the letter up off the table. "Hi Dawn," Dave said in greeting. "Hi Dave," she replied, "Sleep well?" Dave nodded in reply. "So we've got a free house all week then," Dawn said. Her face began to split into a grin."Excellent!" Dave returned her smile. "So are you ready to leave then?" he asked. Dawn glanced up from the letter. "Sure, just let me grab my bag." She ran upstairs and came back down with her school bag. Dave grabbed his keys off the side and followed Dawn out of the front door, grabbing his bag and locking the door behind him. Dawn quickly clambered into the passenger seat of the car and out of the rain; they started the drive towards school. Dave started off slowly; the rain was so heavy he could barely see 5 yards ahead of the car. As he got closer to the school he noticed Mike battling his way towards school, his hair sodden and leaning into the raging wind which whipped fat drops of rain into his face. Dave pressed his horn and pulled over next to him, rolling down the window. "Get in Mike!" he yelled at his friend out the window. Mike whipped his head around and Dave saw him let out a sigh of relief; he quickly got into the car, yanking open the back door and slamming it shut. "Thanks Dave," he said, clearly very grateful for the dry, warm car. Dave turned around in his seat to look at his sodden friend. "Why are you walking today?" he asked Mike, "Don't you have a lift?" Mike peeled off his wet coat and leaned back. "Nope, Mum's gone away and I don't have any other way of getting to school." Dave shook his head. "Why didn't you phone me you bloody idiot? It's tipping it down!" Mike grinned sheepishly; Dave grunted and started to drive to school again. Eventually Dave pulled into school and parked near the entrance to the sixth form block. Dave, Mike and Dawn climbed out of the car and sprinted in the rain to the common room as fast as they could. The three of them arrived at the common room and breathed a sigh of relief; Dawn gave her brother a hug and went to talk to her friends. Dave and Mike found some seats and sat down to talk. As Dave leant back everything went black as a pair of hands wrapped around hisface and covered his eyes. "Guess who?" a voice whispered softly in his ear. Dave grabbed the hands off of his face and turned around; Amy was standing behind him grinning. "Hey handsome," she said, giving him a wet kiss on the cheek and whispering in his ear, "I had a great time yesterday." Dave gave her a hug and returned her kiss in kind. Amy turned away and walked back to her friends. Dave turned around to see Mike staring at him slack-jawed. "What?" he said. Mike just shook his head, dumbstruck. "You sly bastard!" he said, punching Dave on the arm. Dave promptly punched him back. "We've only been on two dates," he said, grinning like a fool. Mike's smile grew impossibly wide and he continued to shake his head. The bell rang out and Dave got up to go to his first lesson. *** Dave leant back in his chair, glad to have a free period on a Monday morning. Maths had been difficult and he had to go over it to learn it properly. As he began to pull books out of his bag Amy sat down in the chair next to him. "Hey stud, how's it going?" Amy asked. Dave turned around in his chair to face Amy; she grinned at him. "Hi Amy, how're you doing?" he asked her. She stretched back in her seat and reached towards the ceiling with her arms languorously stretching, pulling her shirt up to reveal her smooth stomach. "I'm super fine, thanks for asking," she said, dropping her arms back down and placing one hand firmly on Dave's leg. "Your friend looked a little jealous earlier." Mike put his hand on top of hers. "Mike? Why wouldn't he be jealous?" he said, squeezing her hand, "You're gorgeous." Amy's eyes softened; she gave Dave a peck on the cheek and glanced out of the window. "They're saying that if it doesn't stop raining sometime soon the school might flood," she said casually, "What'll we do to occupy ourselves then?" Dave swallowed dryly. "My parents are both away until Friday, so you're welcome to come around my house." Amy leant her head on his shoulder, and he shifted a little in his seat. "I'd like that." *** Dave and his sister got out of the car and opened the front door. It had rained on and off all day, and currently none was falling, but the darkly bruised clouds in the distance told Dave that they could expect another thunderstorm. Dawn gave him a quick hug. "Thanks for giving me a lift." She ran up the stairs to her room and closed the door. Dave sighed and dropped his keys on the side, making his way up the stairs to his room. He fished his books out of his bag and began to do some biology work. As he was working through some notes he was interrupted by a flash of light that lit up his room, followed closely by a booming thunderclap. Suddenly the wind howled and rain lashed against his window. Dave sat at his window and watched the storm. Fat drops of water fell fast and violently, meeting the ground violently and forming rivulets that ran down the side of the road. Every so often and with increasing frequency the sky was split in two by a jagged bolt of lightning, forking through the air for an instant before vanishing. Each bolt was followed by a booming and explosive thunderclap. As the lightning struck with more frequency, the time between the strike and the thunderclap also decreased. Dawn shuffled into his room; she sat down on the bed next to Dave and watched out the window. Dave felt her shudder beside him. "What's wrong?" he asked, concerned for his sister. She placed an arm around his shoulder. "I don't like the storm very much, can I stay with you?" she asked, staring up at him. Dave immediately felt sorry for his sister. "Sure you can," he said, putting his arm around her shoulder as well. "Do you want to watch a film?" Dawn threw her other arm around her brother and squeezed him in a hug. "Only if I can pick it." Dave groaned, he knew his sister would pick something terrible. She walked over to his shelf and browsed through his film collection, finally settling on Willy Wonka and the Chocolate Factory. She put it in the DVD player and sat back down on the bed, pulling up the duvet and climbing underneath. "Trust you to pick this!" Dave said, lying back. He sat and watched the film with his sister, starting to become more and more bored. By the time the film was over he felt relieved. Dawn sat up. "Can we watch another film?" she asked; Dave shook his head. "We've got to make some dinner first," he said. The two of them got up and went downstairs to the kitchen; Dave put some leftover Chinese food in the oven and put on some noodles to boil. The two of them sat down and ate their simple food. "Wow Dave! I never realised you had such good catering skills!" Dawn teased, "You should consider dropping out of school to do this." Dave forced out a laugh. "I didn't see you offering to cook," he said. The two finished and washed up together. Dawn followed Dave up the stairs and when they were in his room she picked another film to put on. It was a long film, but Dave didn't mind this one. Around halfway through he glanced at his watch. "It's getting a little late Dawn," he said "I might go to sleep soon." His words were followed by a peal of thunder. Dawn shivered again. "Can I sleep in here with you?" she asked, rolling over to look at him. Dave thought about it for a moment. "I suppose so," he said, "Do you want to go get changed?" Dawn shook her head. "Its fine, I just sleep in my underwear." Having said this she ripped her shirt above her head and kicked off her jeans. Dave shifted uncomfortably. He was thinking of telling her to put some clothes on but then thought, 'if she's comfortable with it then why shouldn't I be?' Dave shrugged and began to peel off his clothes. The twins sat back and watched the rest of the film. When the credits began to come on Dave turned off the TV and the light. "Night Dawn," he said; she mumbled something in return and rolled over onto her side, facing Dave. He turned over to face away from her and tried to fall asleep. In her sleep Dawn moved closer to him and draped her leg over his waist, throwing her arm across his chest. Dave was painfully aware of the way her breasts pressed into his back. He tried to move out of her embrace, but she simply moaned and pulled him tighter into it. In spite of himself Dave began to feel an erection growing, which was only exacerbated by the sensation of his sister's breath on his neck. He tried to ignore it and after several hours he finally managed to fall asleep. *** Dave's alarm blared out again. He groaned and shut it off; he was once again feeling very sticky. He found himself spooning with his sister when he woke up and tried to pull out his arm from underneath her without waking her up. He showered off and brushed his teeth, which got rid of the sticky sensation. Dawn was already waiting for the shower when he got out. "Good morning," she said brightly. "Morning," Dave replied not-so-brightly. "Can you try and be ready to leave for 8?" Dawn assured him that she would and he made his way to the kitchen to make breakfast. His cereal tasted minty due to the toothpaste and he grimaced as he ate it. Dawn came down exactly on time and they both got in the car. Outside it was still raining, but not as heavily as it had been. Dave checked his phone and saw a text from Mike, wanting a lift. He sighed and made his way over to Mike's house, honking the horn when he arrived. Mike quickly came outside and climbed into the car. "Thanks Dave," he said. They made their way to school and Dave tried to turn into the road when his Maths teacher waved him down. "Hi Dave, hello Mike," he said, "Half the school's flooded, so it'll be closed for a few days while we clear it out." "Thanks Mr. Ericson," Dave said, "Have a good week then." Dave turned the car around and started driving home, dropping Mike back first. Shortly after they started driving from Mike's house Dave's phone began to ring; he threw it to Dawn. "Could you answer that?" he asked; Dawn rolled her eyes and flipped his phone open. "Hello?" she said. "Uh-huh." "Dawn." "I'll tell him that, we'll be there in a couple of minutes." Dawn grinned at Dave. "That was Amy," she said "She wants you to go and pick her up; she also said that she'd packed an overnight bag." Dave grinned at his sister sheepishly and changed his direction, driving towards Amy's house. When he arrived at her house the door flew open and Amy was down the drive before he could even open the door. She clambered in and Dave gave Trish a quick wave before driving off. Amy leaned forwards and gave Dave a kiss, rubbing his cheek before turning her attention to Dawn. "Hi Dawn!" she said, "How's it going?" Dawn turned around to face Amy. "Pretty good thanks Amy," she replied, "It's always nice to see you." Amy and Dawn chatted idly for the rest of the car journey. When they arrived back at Dave's house Amy grabbed her bag and climbed out of the car, following Dave down the path. Dave put his key in the lock and let the two girls in. "So what do you want to do?" he asked Amy. "I'm going to go watch some TV," Dawn said, "You guys are welcome to join me." Dave looked at Amy and she nodded. "We'd love to," she said. Dawn walked into the front room and turned on the TV, flopping onto the sofa. Dave lay down on the opposite sofa. Amy looked at the seat next to Dawn and decided to sit in Dave's lap instead. Dawn began to flick through channels before settling on one that was showing a sitcom. Dave linked his arm around Amy's waist and began to watch the TV; however Amy seemed too restless to concentrate on the television. She snaked her hand around her side and placed it on Dave's upper leg. Dawn seemed oblivious to the proceedings, so Amy began to move her hand up and down Dave's leg, constantly drawing nearer to his crotch. Dave felt Amy's administrations and placed his hand on top of Amy's, looking at her and shaking his head. This seemed only to spur her on, as she moved her hand further up and tried to undo Dave's flies without alerting Dawn. He shifted in his seat and pushed Amy's hand away, but she refused to stop, instead placing her hand through the newly created opening to his jeans. Dave yanked her hand out andheld it in place. On the other sofa Dawn stretched and got up. "I'm going to get some tea," she said, "Would anyone like anything?" "I'm fine thanks," Dave replied. "Me too," Amy added. The second Dawn had left the doorway Amy immediately jumped up and span round. She quickly began to unbuckle Dave's belt. He put his hand on top of hers. "Can we please not do this right now?" he asked, not wanting to alert his sister. Amy pouted at him, but finally nodded. "You're no fun," she said lying back down. "No," Dave replied, "You're just insatiable." Dawn returned and they watched TV for another 2 hours or so before Dave got bored and stood up. "Do you want to go out for some lunch?" he asked. Dawn looked up at him questioningly. "Who?" she asked. Dave thought about it for a moment. "Both of you," he said. Amy jumped up. "I'd love to," she said, giving Dave a quick hug. Dawn stood up as well. "Me too," she chipped in. Dave went and grabbed his keys; Amy followed him into the kitchen. "What should I do with my bag?" she asked Dave. "You can leave it here if you want," Dave replied, trying to find his wallet. "Should I leave it in your room?" she asked; Dave glanced up at her. "That depends on where you're sleeping," he told her, "What did you tell your mum?" Amy started climbing the stairs. "That I was sleeping at my boyfriend's house." Dave saw her throw her bag on his bed and run back down the stairs. Dawn walked into the kitchen. "Ready?" she asked. Dave nodded. "Let's go," he said. *** Dave offered the two girls their seats before he sat down; they sat at a circular table, with the two girls facing him. They ordered their food and relaxed back in their seats. "Sorry I didn't take you anywhere fancy," he said apologetically, "I've just about gone overdrawn, and my savings are just for the car." Amy grabbed his hand underneath the table and gave him a quizzical look. "Why would that be a problem?" she asked him, giggling when he began to blush.
