Please enjoy and send me any feedback. * The sun was shining, its warm rays bathing the world in a soft glow, filling the interior of my car with its radiance. It surrounded my beautiful little sister Katie like a golden halo as her eighteen-year-old form came bouncing out of the school gate towards me. I was shocked to find myself checking out her amazing braless breasts straining against her tight white shirt, hard little nipples clearly visible through the thin material. As she recognized by car waiting her face lit up with that glorious smile that melted the heart of all who were blessed by it. She was soon inside my car, greeting me with a little girl "hi big brother" that made my dick twitch. I quickly accelerated away from the school in an effort to distract my cock from such taboo thoughts. However, Katie chose that moment to bring her feet up against her tight little butt, displaying those glorious smooth legs to my hungry gaze. Now there was no way I could avoid getting a boner, the bulge straining against the material of my shorts. I noticed my sister staring at it with a strange hungry look in her eyes. I though I was dead for sure, any second now she would start screaming at me. Instead she licked her lips and asked me in her best innocent little girl voice "you know big brother, I don't have to be home for a while, can we go to that old lookout you used to take me too when I wanted to look at the stars?" I knew the place instantly, it was practically abandoned and overgrown, very secluded now that no one went up there. With a knot in my stomach I agreed, swiftly finding my way to the spot without crashing the car. Unfortunately a very real possibility with a sexy eighteen-year-old sitting beside me with a top that somehow 'accidentally' came undone to let me glimpse her firm boobs. Katie and I have always had a very close brother-sister relationship, but id never looked at her in a sexual way before today. I hadn't noticed just how beautiful a young woman she had developed into. Pulling to a stop in the sunny lookout, glimpses of a marvelous view still visible through the trees Katie began to talk. She told me all her sexual experiences with the boys at her school, it seemed that my little sister was not as innocent as our parents thought! She told me all about giving a boy a blowjob behind the school toilets until he came on her tits. Also how her current boyfriend had fucked her a month before, it sounded like the poor guy was so nervous he had cum after only a few strokes. I could only stare at my sister with my mouth agape as she told me these things, my cock an iron bar inside my pants. As she talked Katie's hands roamed over her body, squeezing her tits and rubbing up and down her thighs in a way that captivated my attention. Suddenly she turned to me and told me she wanted to be fucked by a real man, a man who could make her cum, someone she trusted. In short, me. I was speechless; my sweet little sister was begging me to fuck her senseless! I couldn't utter a sound as she moved towards me, her school shirt opening to reveal her firm tits and rock hard nipples to my gaze. Her lips were almost touching mine as she whispered to me, looking deep into my eyes all she said was "please big brother." The next thing I knew I was passionately kissing my baby sister as my hands explored her chest and pinched her nipples. Her hands were not idle either; they were running over the bulge in my shorts before beginning to tug incessantly on the material. Breaking our kiss I helped her pull off my shorts and boxers, my hard cock spring out to stand proud in the sunlight. She let out a little gasp as she saw it, nervously wrapping her hand around the shaft as she confided that it was much bigger that the boys she'd been with. Gently grasping her golden curls I guided my sister's head down to my cock, telling her to be a good sister and suck her big brother cock. With a moan at my words she opened her mouth to lick and suck my hardness, lightly at first, but with rising enthusiasm. Her tongue glided over my length, coating my shaft it in her saliva before traveling down to lightly suck my balls into her mouth. With excruciating slowness Katie's tongue traveled back up my cock before she plunged her hot mouth down onto my member. To my great surprise she started to take more a more of my length into her willing mouth, until I could feel my head enter her throat. Soon I was thrusting my shaft deep into her mouth as my fingers stroked her wetness through her white cotton panties. I was in heaven! I was fucking my little sisters' mouth and she was loving every second of it, moaning breathlessly around my cock. I could not take much of this incredible pleasure, holding the back of her head still I thrust my entire length down her throat till my balls were pressed against her cheek. Simultaneously plunging two fingers into her young little pussy I came deep in her throat. My fingers found her g-spot as she pulled back enough to take most of my load in her waiting mouth. I stroked her most sensitive of spots quickly as my seed shot onto her tongue. As my cock started to soften Katie sat up, my fingers still deep inside her, before opening her pretty eighteen-year-old mouth to show me the pool of cum I had deposited on her tongue. With a groan I told her she was such a naughty girl, her answer just a wink and a deep swallow. Opening her mouth to show me it was empty she leaned in to kiss me, our tongues dueling over the taste of my seed. My fingers were still twirling inside her tight wetness as I lowered my mouth to her amazing firm boobs. I gently licked her nipples before sucking as much of her breast into my hungry mouth as I could, her breath coming heavily in my ear. Reluctantly leaving her heavenly mounds I whispered to my sister that I wanted to taste her pussy. Her eyes widened as she stammered that no one had ever done that to her before. I silenced her with a kiss and a promise that she would love it, my fingers massaging the inner walls of her pussy in exclamation. Seeing her nod I guided her out of the car and around to the grass in front. Slowly stripping off her uniform I placed soft kisses over Katie's body, her breathing becoming ragged as I approached my target. Gently lowering her onto the bonnet of my car my mouth found her soaking wet bald pussy already flowering in anticipation. My shock that my 'innocent' sister shaved herself bare was swiftly replaced by my desire to please her with my tongue. I slowly teased her outer lips, making her thrust into my face, trying desperately to get my mouth onto her clit. I wouldn't be rushed, I took my time exploring every fold of my parents' little angel's slit. Only after she grasped my hair did I use my hands to spread her nether lips and plunge my tongue into her wetness. Hearing her gasp with pleasure I plunged two fingers into her sopping pussy, seeking her g-spot as my tongue found her clit. I pumped my fingers furiously as my tongue circled her hard nub. As I found her g-spot I covered her clit with my mouth and sucked hard, the duel sensations too much for her inexperienced body. With a scream she came, her back arching to catch the sunlight on her tits and her pussy coating my face with her juices. Standing I positioned the head of my hard cock at the entrance of her pussy before leaning close to her ear and whispering "do you want your big brother to fuck you sis?" Her response was simply to grasp my hips and pull me into her. We both let out deep moans of pleasure as my member entered her body, she was incredibly tight and wet, her inner muscles gripping my like a magnificent vice. I moved my fingers to her clit as I started to thrust into my sister with short strokes. My tongue dueled with hers as I finally buried myself in her love tunnel. The feeling of fullness sent Katie over the edge again; she came on my cock, her inner muscles rippling along the length of my shaft. I had to pull my cock from her shaking body and hold her close until she came back from her second massive orgasm. When her eyes finally opened she blessed me with a beautiful grin before flipping herself off the car. In front of my eyes my little sister knelt on her discarded school uniform and bent down onto all fours. Looking over her shoulder at me she reached between her legs to spread her lips for me. The wetness of her pussy was glowing in the sunlight as I knelt behind her and eased in my cock. Gripping her hips I started to thrust into my sister pliant body hard, burying myself with each stroke. With my balls slapping against her clit I reached under Katie to grip her swinging boobs in both hands, kneading them in time with our fucking. We fucked like that out in the sun for what seemed an eternity. Alas all too soon however I could feel my orgasm approaching. I wanted to make sis cum once more first however, so holding her tits in one hand I wet the index finger of the other with my mouth before easing it into her tight little virgin ass. It had only penetrated to the first digit when she came, her orgasm ripping through he body so hard that she collapsed onto the grass, my cock springing from her well fucked pussy with a pop. This left me with a straining dick and an urge to cum. Seeing her firm butt cheeks in front of me I quickly straddled her hips and started to thrust my cock along the crack of her ass. Katie soon realized what I was doing and started to thrust back onto me as I gripped her shoulders for extra leverage. Feeling my impending explosion I whispered in my sister's ear that I wanted to cum on her tits, a breathless moan all the agreement I needed to lift myself off her hips and roll her over. Folding her firm boobs over my shaft I gave the soft flesh a few thrusts before letting out a bellow and cuming all over my little sisters eighteen-year-old breasts, my thick gooey seed splattering her chest and throat in the sunlight. With a smile Katie started to scoop up the mess and lick it from her fingers, moaning in appreciation at the taste of her brothers cum. Unfortunately it was getting late so we had to hurry to make ourselves presentable for our parents and come up with a plausible excuse for our tardiness. As I drove us home Katie watched me with a cute little smile on her face. It was only as we pulled into our family driveway that she lent over to suck my earlobe and whisper "I had fun today big brother, maybe next time ill let you fuck my ass" How in the hell was I meant to walk into the house now sporting a huge hard on? With a giggle she stepped out of the car and ran into the house, her butt jiggling with every stride. I couldn't wait for next time. My Naughty Sister Ch. 02 Part 2 of the fictional adventures of my naughty little sister and I. Please send me any feedback. * I was having the most amazing dream. In it my gorgeous eighteen-year-old sister Katie had snuck into my room while our parents slept and started to suck my hard member as I slept. I could see her running her petite tongue over my shaft, swirling around the head, before plunging her hot mouth down onto my hardness. Her little hand squeezed my balls as she sucked me deeper into her hungry mouth, till the head passed into her throat and her nose pressed against my abs. With a start I awoke. Disorientated I looked down to find a beautiful pale skinned nymph between my legs, her golden curls bobbing with the movement of her mouth onto my cock. Sensing my awakening, my little sister raised her mouth of me just long enough to whisper for me to be quiet so we didn't wake up our parents in the next room, before moving to lick my balls and suck them into her mouth one at a time. With one final suck she released my nut before licking and nibbling her way back to the tip of my rod. After bathing the glands in saliva Katie took my cock deep into her throat in one smooth movement, holding it there before lifting up for a breath and a repeat performance. As she continued to plunge down onto me I couldn't help but start to thrust into her young mouth in time with her strokes. Soon we reached a wonderful rhythm where my rock-hard cock was fucking my sister's pretty face, her big boobs rocking underneath her in time with our movements. Her stifled moans stimulating me more as her throat muscles rippled around my shaft. I could feel myself getting close as Katie's hand appeared from between her legs; it was glistening in the moonlight with her juices. Feeding it to me, she let me taste her delicious pussy as my cock disappeared into her mouth, her fingers preventing me from moaning out loud. This was too much for me as with one final thrust I exploded inside my little sister's willing mouth. She didn't miss a beat, as her mouth was flooded with my seed she swallowed it all with a moan of satisfaction, and then cleaned me up with her tongue. I couldn't believe that I was awake and not dreaming, my beautiful little sister had just sucked me off while our unsuspecting parents slept in the next room. With a final loving lick, Katie left my cock and made her way up my body, her hard nipples grazing their way ever higher until she could kiss me passionately, her tongue dueling mine so I could taste my salty cum. As we continued to kiss I wrapped my arm around her naked form and pulled her tight to me, her firm young breasts squashing against my chest. My other hand quested lower, over her smooth butt to her bald wet slit. Feeling me begin to rub circles around her engorged clit Katie began to moan into my mouth and gently hump my recovering prick. Sensing her need for release I began to alternate stroking my sister's clit and plunging two fingers into her juicy hole. She definitely appreciated my actions as she was practically smothering me with her kisses; her thrusts bringing my cock back to life in record time. Without warning I entered her soaked pussy with my reenergized member, burying it to the root in one smooth motion. Katie reacted as though electrocuted, her back arching and her thighs locking me in place so she could savor the sensation. I gave the little vixen no respite, taking hold of her butt in both hands I started to thrust into her pussy in long deep strokes. With her clit rubbing against my stomach with each movement of our bodies, and my cock filling her up, my sister was getting very close. I wet my finger with her copious juices and gently inserted it inside her tight eighteen-year-old ass as I fucked her pussy hard. Her moan of surprise and pleasure was barely contained by my mouth, and for a moment I feared our parents awakening. Such thoughts were quickly dispelled from my mind however as I added a second finger to Katie's hot little asshole, plunging them both into her to the second knuckle. As my fingers began to work her ass in time with my hard thrusts into her pussy I whispered into my sister's ear to cum for me. She needed no more urging, with one final thrust that buried both my fingers and cock deep inside her holes Katie came. It was necessary for me to slide two fingers from my free hand into her mouth for her to suck urgently in order to stifle her scream of ecstasy as she had a mind-blowing orgasm. I could feel the muscles of both her holes rippling over my members as she drenched my balls with her love-juice. As she recovered, I extracted myself from her holes and held her tight. After a few quite minutes of loving embrace my little sis began to thrust again, this time stimulating my cock by running it through the cleft of her butt. With each action her wetness was spread from her gushing pussy to her butt hole, the feeling restarting her moaning. Reaching to my bedside table I extracted a tube of lubricant from the drawer. Squirting a generous portion onto my fingers I massaged it into her pucker before plunging two fingers back inside to make sure she was loose enough for my cock. Finally satisfied I coated my cock with another helping of lube, my hardness straining with the need to be inside her body again. Throughout all this all my little sister could do was moan at the feeling of my invasion of her most private place. Bringing my mouth close to her ear I whispered, "I'm going to fuck your ass sis" before sucking on her earlobe gently. Her response was a breathless yes as she reached behind herself to grasp my cock and guide it to the entrance of her ass. With a gentle rocking motion the head eased it's way inside, both of us groaning in appreciation. After giving her a minute to get used to the sensation I restarted our rocking motion, slowly slipping my shaft into her incredibly tight hole till my balls rested against her butt. The feeling of being completely buried in my gorgeous sisters ass was indescribable, as we both savored the sensation I brushed her golden curls from her face and kissed Katie deeply. Looking deep into her eyes I began to move in her ass, ever so slowly pulling out till just the head remained, then sliding back in fully. As I repeated this action over and over my little sis began to match my strokes with her own, the speed increasing steadily. Before I knew it we were fucking in a beautiful rhythm, my balls slapping against her butt cheeks as I stretched her orifice and made her moan softly in ecstasy. Sitting up, I rolled us over till I was on top on Katie, my hard cock still deep inside her body. Pushing her legs up till her knees rested against her breasts I started to fuck her ass with abandon. I watched as Katie reached between her legs to rub her sensitive clit, the look of wanton lust in her blue eyes all the confirmation I needed to keep up my assault on her tender butt. With my room full of the sound of our bodies joining, undercut with our stifled moans, we were past caring if our parents heard us. Relinquishing my hold on her legs I plunged two fingers into her quivering pussy and thrust them in time with my cock in her ass, my other hand finding her luscious breast and pinching her rock-hard nipple roughly. This pushed her over the edge again, with her mouth open in a silent scream my little sister came again, her ass clenching down on my cock as her body was racked by spasms of pleasure. With a soft 'pop' I pulled my cock from Katie's ass, before rolling her over onto her stomach while she lay dazed and unresisting. Placing a pillow under her hips and spreading her cheeks with my hands, I admired the sight of her dilated asshole before me in the moonlight. Without hesitation I dove in and began to lick her ravaged star. It took sis a moment to realize what I was doing, but soon she was moaning in appreciation as my tongue plunged into her well-fucked ass. When she started to thrust back at me I knew she was ready, moving onto my knees I positioned my cock and rammed into her little hole again. With my sister's scream of pleasure muffled by my pillow I pounded her young asshole as hard as I could, my cum-filled balls slapping against her pussy with every stroke. I could not keep this up for long; soon I felt the start of my eruption. Clenching my teeth to prevent myself from making sound I buried myself in my sister's asshole and let loose. I saw stars as my cock squirted a huge load into Katie's bowels, I could vaguely sense her cuming again at the sensation as I fell forward on top of her. As I returned to reality, I pulled myself from Katie's gaping butt and rolled off her. Snuggling close my sexy little sister thanked me and told me that I could fuck her like that anytime. It was all I could do not to have my way with her again right then as she kissed me softly before rolling out of my bed and walking gingerly toward the door. I could only admire her wonderful naked form in the moonlight as she stopped at the door to whisper "goodnight big brother" before tip-toeing back to her room, a rivulet of my cum flowing from her ravaged pucker down her leg. My Naughty Sister Ch. 03 The next story in the adventures of my fictional naughty little sister and I. Thanks to those who sent me feedback on the previous chapters, it is all much appreciated. I awoke with the bright Saturday sun streaming through my blinds, the golden rays bringing a soft glow to the air. I couldn't help but compare the sight to my little sister's blonde curls, the way they framed her face and drew attention to her sparkling blue eyes. Just thinking about Katie made my morning wood ache, the eighteen-year-old vixen had been teasing me mercilessly for the past week, always giving me glimpses of her magnificent body while our parents weren't watching. The crunch had come when we were eating dinner as a family two nights ago and she had rubbed my hard-on under the table while talking to about school to mum, before feeding me her fingers covered in her delicious pussy juice while the oldies were distracted. Alas we hadn't had a chance to release our sexual tensions, but today was different. Today I knew our parents had gone away for the weekend, leaving me to look after my little sister, an assignment they thought I despised. If only they knew! Walking into the kitchen fresh from my shower wearing only a pair of boxers I spied Katie making a sandwich at the counter. She looked stunning in a long t-shirt, her well-toned legs drawing my eyes, not to mention her firm teenage breasts standing proud under their thin covering. As I stood in the doorway and admired my oblivious little sister she reached up to the top shelf to fetch a plate, the shirt riding up to expose her bare bottom. The sight of that pale naked flesh bringing an instant rise from my member, the head poking its way from the fly of my suddenly too-tight shorts. Moving softly across the smooth tiles I crept up behind Katie and enveloped her in a warm embrace, my cock finding its way between her thighs to nestle against her soft folds. Her startled cry was quickly cut short, replaced by a moan as I began to kneed her boobs and pinch her nipples through the shirt. My mouth planted kisses up the curve of her beautiful neck till my mouth was level with her ear. With a whispered "good morning sis" I began to rub my hard cock along the length of her bald pussy, her quickly spreading wetness coating my shaft and making the kitchen fill with the marvelous aroma of her sex. Neither of us could wait a second longer, pulling her shirt off, leaving Katie in all her naked glory, I bent her at the waist until her breasts were squashed against the counter. This left her tight young pussy at a perfect height for me to enter in one smooth thrust. As my balls came to rest against her engorged clit we both let out loud moans of appreciation. Her eighteen-year-old pussy was a velvet glove encasing my hard shaft as we began to move in harmony. With each stroke the head of my member would go from the entrance of her nirvana to it's deepest depths, before repeating the journey seconds later. It took only a few minutes of this heavenly assault for sis to start cuming, her pussy gripping my cock in a indescribable embrace as she shouted out her pleasure. I gave her no rest, gripping her shoulders I began to thrust into her body with furious strokes, my heavy balls slapping against her clit with every movement. Katie let out a strangled scream as she exploded again, her entire body shaking with the force of her duel orgasms. Easing from my sister's sopping pussy I stepped back to allow her room to stand and turn to face me. Standing on shaky legs Katie kissed me passionately, her tongue dueling with mine as her hard nipples pressed against my chest and my straining cock was wedged between our sweaty bodies. With the mischievous twinkle in her eye that I love so much sis slowly kissed her way down my body to my rigid member. Maintaining eye contact she gently blew on my penis, the warm air making it twitch, much to her amusement. Wrapping my hand through her soft curls I guided her mouth onto my cock, the feeling of my head slipping into her warmth making me fill the kitchen with my moans. Without prompting my sexy little sister sucked me deep into her mouth before starting to bob her head in an excruciatingly pleasurable rhythm. With my hand on the back of her head I started to match her motions with my own. Pausing only to bath my cum-filled balls in saliva, Katie let me fuck her face with long joyous strokes. Relaxing her throat muscles my incredible girl took my cock deep in her throat till all eight inches had disappeared into her willing mouth. I could take no more, with a groan I spurted my load into her hungry mouth, Katie moaned in contentment as she tasted my hot seed upon her tongue. Slipping my softening member from her mouth Katie showed me the puddle of my sperm she had collected upon her tongue before swallowing deeply. Lifting my wonderful sister to her feet I kissed her deeply, our tongues sharing the taste of my cum between them. Letting my hands roam over her form I kneaded and squeezed my way to her firm butt. With our tongues entwined my hands squeezed her glorious cheeks and pulled her body against mine. Reaching lower I scooped up a generous helping of her juices before depositing them against her little puckered butt hole. Repeating this several times I was able to slowly ease my finger into her incredibly tight orifice, my actions generating renewed moaning from Katie. Spying a bottle of cooking oil on the shelf I spun Katie around till she was again bent over at the waist over the kitchen table. Easing my digit from her warmth I dropped to my knees behind her before burying my tongue in her wet folds. Sis cried out in pleasure as I found her clit and sucked it into my mouth, her hand reaching back to pull my head closer to her crotch. Alternating between flicking my tongue over her sensitive clit and plunging into her wet hole I greased her asshole with a generous helping of oil before slipping first one, then two fingers inside her butt. My other hand lubed my hardening cock as Katie begged me to make her cum again. Being a proper gentleman I could not do anything other than honor such a request. Taking her clit in my mouth I gently grazed it with my teeth before sucking it hard as my fingers plunged into her slowly loosening ass. It was only a matter of moments before my little sister was thrusting herself madly onto my face and fingers as she experienced another glorious orgasm. I could feel her ass clench my fingers tightly as my face was bathed in her delicious love-juice. After licking her clean I stood to position my hard cock against her winking ass. Easing forward the oily head disappeared into her body with a soft pop. This generated an immediate response from Katie, her back arched as she thrust back against me, my entire shaft disappearing into her tightness in a series of movements. Feeling my balls resting against her pussy, sis pulled me down for a rough kiss before demanding "fuck my ass hard big brother, make me your little slut" With a groan at the nasty words my 'innocent' little sister was producing I started to fulfill her request and pump my shaft into her ass in long strokes. As I repeatedly buried myself completely in her willing butt my balls slapped against her pussy with every stroke. As she matched my thrusts, her fingers furiously strumming her clit, our combined moans were so loud I momentarily feared our neighbors would hear. I forgot all about the neighbors as I lifted Katie up with my shaft buried inside her ass, and pressed her against the fridge. With the cold metal pressing against her diamond-hard nipples I continued to pound her tight eighteen-year-old butt. By this point sis had no idea what day it was as her body was continually racked with orgasms, each merging with the next until it seemed she was cuming continuously. With my legs beginning to tire I crab walked us over to a dinning room chair before sitting down heavily. Gesturing for Katie to straddle me I slipped my cock back into her ravaged asshole as we kissed with furious passion. As I pinched her sensitive nipple my other hand ground our crotched together, the friction against her clit sending her over the edge again as she threw her head back and screamed. The force of her climax was too much for my straining cock; with a bestial roar I came deep inside Katie's ass, my seed filling her bowels with warmth. I not sure how long we sat there with my slowly softening cock still buried in my little sister's body. Eventually Katie raised her head and kissed my gently, then looking deep into my eyes she said "thanks big brother, I needed that" to which I could only respond "anytime sis." With a final loving hug I lifted her up and carried her to the shower, a small voice in the back of my mind reminding me that we still had all weekend before our parents got home. My Naughty Sister Ch. 04 The fourth chapter with my fictional little sister. Thanks to those who sent constructive feedback for the previous chapters, anything that helps with my writing is much appreciated. * It was a magnificent Sunday; the sun was casting its golden rays upon a grateful world. Not a breath of air could be felt while birds sang and frolicked amidst the trees. Enjoying the day was my family and I, sitting in an otherwise deserted picnic area finishing our barbeque lunch. On one side of the table strewn with the remnants of a delicious meal sat my parents. On the other was my eighteen-year-old sister Katie and I, her golden curls catching the light and drawing attention to her dazzling blue eyes. I couldn't help but sneak glances down her wondrous form clad in a thin summer dress, the smooth skin of her shoulders giving way to her deep cleavage just begging for my touch. While under the table her seemingly endless legs were pressed against mine, a constant reminder of our past adventures together. Dad was telling stories again, the ones we'd all heard a million times but still had to appear attentive too. It was all I could do to keep my eyes open as he droned on and on. It was in the middle of one of his oldest and most boring tales that I felt a hand rubbing my thigh, the gentle touch sending an instant lightning bolt through my system. Casting a sideways glance at my little sister I could see the corner of her mouth curling as the hand in question traced it's way closer to its prize. Every millimeter of skin traveled on it's journey heightening my anticipation a hundred fold. She picked her moment to perfection; just as I was dutifully laughing at one of dad's jokes her petite fingers found my member, circling it through my shorts. It took all my self-control not to moan out loud as Katie started to massage my package under the table while chatting to our parents. It was not long till she was stroking my hard shaft with long rhythmic motions, heightening my arousal to it's maximum potential. Not to be undone by my naughty little sister, I also stealthily moved my hand under the tabletop. I waited till Katie was telling mum about her latest school assignment before gently stroking her smooth thigh. I don't think anyone else noticed sis jump as my fingertips trailed ever so softly along her skin. Circling lazily, I teased her for minutes on end, her hand becoming more insistent on my cock by the minute. Her legs opened wider without conscious thought as my questing hand continuing it's slow inexorable journey to her panty-clad treasure. It must have seemed to Mum that she was having trouble explaining her schoolwork, yet I knew better. As my fingers reached their goal a small sigh escaped her lips, luckily neither of the oldies noticed. The hand on my cock was stroking rapidly as I rubbed her smooth mound through the sheer panties encasing it. Done with my initial exploration of my little sister's crotch, I moved on to the next level. Slowly pulling the soaked cloth aside, I ran my fingers over my sister's soft, wet folds while discussing the pros and cons of all the sports teams this year with dad. Mum was starting to pack the leftover food into the cooler, completely oblivious to my actions under the table as I circled her little girl's clit. Out of the corner of my eye I saw Katie leaning back on the bench, this was my queue to spread her nether lips and slowly sink two fingers into her waiting hole. The heat emanating from her tight eighteen-year-old snatch felt like it would burn my fingers as the wet walls clenched my digits. Her hand was merely gripping my shaft now as my fingertips searched out every corner of her tunnel, making sure I didn't miss a single square millimeter. When I found her g-spot Katie jumped slightly, her toned thighs rapidly clenching and releasing my hand. Massaging her most sensitive spot with increasingly rapid movements I couldn't help but smile. I love nothing more than pleasuring my little sister, and doing so in such a risky situation just added to my enjoyment. I distracted our parents with a tale about something or other as my little sister's heaving chest with its rock hard nipples readily apparent through the dress drew my discreet glances. Turning to each other our parents were planning an after lunch bush walk. Seeing their lack of attention I lent close to Katie's ear and whispered "cum for my sis" while thrusting my fingers repeatedly into her squishy pussy and rubbing her engorged clit with my thumb. She needed no urging as her body was rocked by a powerful orgasm, her teeth clenching to prevent a moan escaping her lips. Her eyes were screwed shut as her head was thrown back by the pleasure coursing through her body. The sun caught her hair and turned it into a golden halo that took my breath away. As sis came back to reality her now shaky thighs released my hand from their vice-like grip. I couldn't pass up the opportunity to bring my fingers to my mouth and taste her delicious juice. My sister's eyes were locked on my every move as I licked every trace of her nectar from my digits. The taste and smell of her heavenly wetness made me moan softly, my cock a steel bar in Katie's hand, staining against my shorts. Mum and Dad picked that moment to turn back to us and lay out their plan for a long bush walk to help digest lunch. Mum immediately commented on Katie's flushed state, her concern for her baby girl clearly evident. Sis covered nicely with an excuse about the sun being so hot on her fair skin. Mum had no way of knowing about the love juice soaking into the picnic bench under her little darling, or that her hand was running over her big brother's engorged cock the whole time she was speaking. I stepped in at this point to explain how I thought Katie was in no condition to go walking in the hot sun. Wouldn't it be better if she stayed here and rested in the shade? I even managed to make myself sound less than pleased to be volunteering to stay behind and look after her. To my immense relief they bought my story, agreeing to my plan and standing to leave with a final comment on what a nice big brother I was. Our parents had barely disappeared into the tree line when Katie and I engulfed each other in a crushing hug and passionate kiss. Her hand was desperately trying to release my hard cock from its confines as I squeezed her magnificent big boobs and our tongues dueled in our locked mouths. Our sibling love was palpable as we tore at each other's clothing while maintaining our extremely erotic kiss. Freeing her mounds from the dress encasing them I exposed their glory to the warm sunlight, the little bullets of her nipples standing proud. With a final kiss to her soft lips and a lustful look of silent communication I moved down to worship them with my mouth and tongue. My young sister moaned loudly as I covered her breasts with kisses before alternating between each hard nipple, sucking them hard. I was enjoying myself immensely as I sucked as much of her tit flesh into my mouth as possible. My hand gripped and squeezed her hard nubs as I made my way down into the deep valley of her cleavage, her breasts pressing against both my cheeks as I traced my tongue up the valley between them. Emerging back into the light I kissed my way up Katie's slender neck to her mouth, finding her lips parted and ready for my loving kiss. Pushing me away from her Katie bid me stand and rest my buttocks against the picnic table in front of her. This left my straining member directly in front of her beautiful face, a thin layer of material the only thing between her and it's quivering shaft. Gripping my waistband in both hands she drew down my pants, my cock jumping out dramatically, grateful for the freedom of the great outdoors. Looking me in the eye, her blue orbs captivated me as my little sister stretched out her tongue to tease the tip of my rod. I could only groan in appreciation as she slowly traced her tongue along my shaft, making sure she didn't miss a single spot. Eventually making her way to my balls she took first one, then the other into her heavenly mouth, sucking them gently. My breath was coming raggedly as her tongue traced its way back up my cock before her mouth plunged down onto me. With the warmth of her mouth encasing my cock, it was all I could do not to cum. My hands rested in her hair as she slowly drew more of me into her mouth, her hand playing with my balls as the other stroked her own wetness. Moving back to take a breath Katie winked at me before taking my saliva coated shaft deep in her throat, before my astonished eyes she didn't stop until my heavy balls rested against her chin. The feeling of her throat muscles massaging my shaft was indescribable. With the warm sun on our skin I wrapped my hand in my little sisters' hair and started to gently thrust myself within her mouth, her moans all the encouragement I needed. Finding a glorious rhythm my naughty sister allowed me to fuck her mouth and throat to my hearts content, the picnic area becoming filled with the sound of lewd slurping and sucking. After several thrusts she would pull back for a breath, sometimes followed by a quick lap of my heavy testicles, before plunging back down onto me. It did not take much of this amazing attention for me to feel the signs of my impending orgasm; it started down in my toes and rapidly traveled up to my crotch. With a final thrust that buried my cock in her throat I erupted. I saw stars as my seed pumped into Katie's throat and mouth, a small rivulet appearing at the corner of her lips as she was unable to swallow it all. My penis continued to twitch as she cleaned me of any trace of cum, moaning at the taste as she swallowed deeply. Raising her up I kissed my beautiful girl deeply, tasting myself on her tongue as my hands explored her body. Stripping each other completely in a flurry of passion, we pressed our warm bodies together as we bathed in the sun's glow. I desperately wanted to taste my sister, laying her gorgeous form on the picnic table where our parents had sat so recently I positioned her so that her delicious wet pussy was at the edge in front of my waiting mouth. With her boobs standing proud in the sun I spread Katie's legs and admired her beautiful hairless nether regions, her pink lips opening in anticipation of my tongue. A delicious looking sheen of juice coating her thighs and pussy, the hard nub of her clit peeking from beneath it's hood. Teasing her slightly I cleaned the wetness from her thighs, my tongue tracing lazy circles on her sensitive flesh. Hearing her demands to stop teasing, I dove in to slurp her juices with gusto, my tongue exploring her folds and circling her hard clit. Her hand came to rest on my head as I spread her lips to grant me access to her slit, my tongue plunging into her body like a miniature penis. With my mind filled with her moans and the delicious aroma of her pussy I could feel my cock coming back to life in record time. Forcefully moving my mouth to her clit Katie begged me to make her cum. The gentleman in me couldn't say no to a request like that. Taking the hard bundle of nerves in my mouth I sucked it hard, my tongue swirling over it incessantly. Burying several fingers in her quivering love tunnel I sort out her g-spot and massaged it in time with my tongues movements. I kept this up for only a very short time before she hit climax. With a scream that startled the birds Katie came, her back arching of the table and her thighs locking me tight against her crotch. I could feel her pussy clenching around my fingers as I struggled to lap up all her love juice, my face swiftly becoming covered. As her body started to relax I quickly stood and positioned my re-energized head against the mouth of her pussy. With one smooth thrust I buried myself in her wetness, our moans of pleasure merging into one. As my balls came to rest against my little sisters butt she came again. A small orgasm making her face contort in an image of pure lust as she moaned my name. I gave her no time to recover, thrusting my hard cock into her pliant body in long strokes. Pulling back till just the head was inside I would plunge forward to the hilt, repeating the process over and over. I felt amazing to slide into her pussy as she wriggled on the tabletop, her boobs catching the sunlight. Leaning forward I maintained my rhythm as I sucked her nipple into my mouth once again. Quickly tiring, I joined Katie on the tabletop, pulling her on top of me for a passionate kiss. With her tongue madly licking her own juice from my face, sis straddled me and sank down onto my cock, her hips rotating to enhance our pleasure immeasurably. My hands came to rest on her firm butt cheeks as she gyrated on my shaft. Grinding herself against me her nipples were spearing into my chest as we once again explored each other's mouths with our tongues. Raising herself up I was able to massage her tits as sis started to bounce on my cock, the head penetrating deep into her body with every stroke. I lay back and admired my sister's beauty in the sunlight, her head lolled backward with her eyes closed, completely overcome by lust. Her body seemed to be moving without conscious control as she drew herself up before slamming back down onto me, my rod stretching her pussy lips open like the petals of a beautiful flower. Slipping my hand lower I was able to massage her clit as she slid her body up and down my cock. A soft chanting of "oh my god" and "fuck me" filled the picnic area as she satisfied her primal urges. Leaning close to me, my little sister locked my gaze with her bottomless blue eyes and ordered me sternly: "fuck me doggie big brother." Without further words she slipped of my cock, the air cold against my wet member. Carefully stepping down from the table top Kate positioned herself at the end of the table and bent forward at the waist, pressing her boobs against the tabletop. Seeing her in this incredible erotic position I was off the table and behind her in a flash. Gripping her hips firmly I sank home into her pussy with a sigh of pleasure echoed by both of us. As my balls slapped home against her clit I pulled myself tight against her tight buttocks, enjoying the feeling of being buried in my eighteen-year-old sister's body. Her inner muscles were clenching my shaft as I withdrew half way and plunged back in fully, the air being expelled from her lungs with the force of my thrust. Starting to pump furiously I slammed myself into Katie's pliant body, her groans of pleasure egging me on. With each thrust I would withdraw till only the head remained inside her body, then with a single movement I would be buried once again to the hilt, my balls slapping her clit loudly. I kept this up for several minutes, sis matching my movements with her own. Her hips were moving in erotic circles as her butt cheeks rippled with the impact of my assault, the wet slapping sound of our joining loud in our ears. With a final hard thrust she came, her mouth opening in a silent, breathless scream as her body convulsed with the power of her orgasm. My cock left her body with a wet slurping sound as she collapsed forward onto the table. Katie's body was shaking with aftershocks as I wrapped her in a loving embrace from behind. My hardness nestled between her beautiful cheeks as I held her tight and kissed her hair softly. She finally returned to earth after several minutes, slowly turning to face me and planting the most sensual kiss I have ever experienced upon my lips. As it ended I was left gasping for breath, my cock a steel bar against my sister's belly. Feeling it pressing into her sis slowly lowered herself to her knees on the soft grass, her nipples dragging twin trails of fire down my body. Watching my face intently, Katie blew me a kiss before wrapping her lips around my hard member, slurping it wetly. With sisterly tenderness she made sure I was completely coated in saliva before pulling herself off my shaft. My squawk of protest was cut incredibly short as she proceeded to wrap her magnificent breasts around my cock. Looking up at me she told me in her best little girl voice to "fuck my tits till you cum big brother." I needed no urging, sliding my rod between her mounds I was in nirvana, the soft flesh encasing me while her tongue snaked out to lick the tip of my head on every thrust. Seeing my cock between my little sister's glorious boobs sent me over the edge, my head lolled back as my moan filled the picnic area. My cock pulsated madly as my hot cum splashed over Katie's boobs and throat, one particularly forceful spurt striking her square on the nose. I almost blacked out as she took my super sensitive cock in her mouth and sucked my clean, swallowing the remnants of my seed with gusto. To my amazement she then proceeded to scoop up all the cum she could find plastered on her body and gobble it up like it was her favorite treat. When she finished I lifted her up gently and wrapped her in my arms, placing a loving kiss on my little sisters lips. Our unsuspecting parents returned half an hour later to find Katie and I snoozing on the grass in the shade under a tree. We were both dress exactly as we had been when they left and they were very pleased to find their little angel was feeling better. I received their thanks for staying back with her with great modesty, a private smile passing between my sister and I as we contemplated exactly how I had taken care of her. My Naughty Sister Ch. 05 The water droplets tumbled gracefully, each one catching the golden light and reflecting it in a dazzling display of sparkling wonder before smashing against my skin. With a sigh I soaped my form, enjoying the warm showers affect on my tired muscles. As each region of my body protested vigorously against my recent physical activities, my mind drifted back to how I came to be in this state. It had happened last night, my little sister Katie and I had decided to go see a movie at the local drive-in theatre. It had been a warm summers evening with the stars twinkling serenely as we said our goodbyes to Mum and Dad and piled into my car to make the trip to the theatre. It was as we were pulling out of our family driveway that I first came to realize that I was in for more than soda and popcorn. The night air filled our lungs as we roared down the bitumen with both windows open. Out of the corner of my eye I noticed Katie brush her golden curls from her face before flashing a sly grin that made her bottomless blue eyes sparkle in the streetlights. Running her dainty pink tongue over her moist lips she slowly slid her hands over her wondrous form. Lower and lower her fingers descended, captivating my attention to the extent I had to force myself to pay attention to the road. Thankfully there was next the no traffic this time of night. Squeezing her large cotton-clad breasts briefly, she moved on down her toned stomach. Reaching her short plaid skirt, sis raised it up her smooth thighs with excruciating slowness, gradually revealing more of her gorgeous pale limbs to my hungry gaze. Finally reaching the object of my desire Katie gave my gaze free access to her panty-encased mound. Her delicious bald pussy remained hidden to me only by the skimpiest piece of black lace. A soft moan escaped the little vixen's lips as she rubbed her fingertips over her slit, the panties instantly becoming stained with her wetness. The car was slowly filling with the wonderful smell of my sister's pussy as she rubbed harder and harder. Her moans of pleasure were only interrupted intermittently as she stole glances at my lap, my cock forming a rather obvious tent in the crotch of my pants. I very nearly ran off the road as Katie hooked her fingers under the edge of her soaked panties and pulled the crotch aside. There in all its wonder lay my little sister's eighteen-year-old pussy, glistening in its excitement. I drank in the sight before my eyes as she slid first one, then two fingers into her love tunnel with a highly erotic squishing sound. Curling her fingers she extracted a large sample of her sweet nectar before offering it to my lips. Katie watched with mounting lust as I sucked her fingers clean, the taste of her young pussy flooding my mouth. Finally when I could clean them no more sis took back her digits. Leaning her head back against the seat, she began to work her fingers in and out of herself. Developing a nice rhythm, Katie's moans filled my world as she masturbated beside me while we drove down the dark road. It soon reached the point where I could stand being a spectator no longer. Taking one hand off the wheel I pulled up her top to release her marvelous orbs. Her firm young breasts sprang free, eager to be done with their confinement. Pinching her pink little nipples to attention, I drove with one hand on the steering wheel and the other squeezing sis's firm tit-flesh. Noticing that we were nearing out destination, I popped two fingers into Katie's hot mouth. She sucked them hard, her velvety tongue massaging my digits in a way that sent urgent messages directly to my cock. The motions of her lips matched the speed of her fingers pumping into her soaked gash. As I watched from the corner of my eyes, they would slide as deep into her soaked passage as possible, moving in circular motions to massage her inner walls, before pulling back to the entrance and repeating the journey. As we pulled into the theatre entrance way I pulled my fingers from her mouth with a 'pop'. Her lips searched in vain for the return of my digits, but they had other ideas. My now wet fingers found their way to her aching clit, free from its protective hood and begging for attention. With a sideways glance to make sure her eyes where tightly closed I rubbed her little nub hard as she pounded her hole. Timing it to perfection, Katie's orgasm overcame her at the exact moment that we pulled up at the ticket booth. The worker appeared no older than sixteen as he stretched his hand out for my money, only to be greeted by the sight of my sister's incredible near-naked form being racked with pleasure. The poor young bloke's eyes nearly popped out of his head as sis's moan filled the air, her large firm boobs stretching towards the roof of my car as my fingers continued their assault. Handing over my money with my free hand, the lad gave me our tickets without a word, his eyes still riveted to Katie as she body continued to be overcome with convulsions. With a knowing smile at the large bulge in his uniform trousers I drove away from the stunned young man and into the theatre lot. I made sure to park in a dim section far from other cars; I didn't want us being disturbed. Killing the engine, I turned to my nearly comatose looking sister and planted a tender kiss on her slightly parted lips. She instantly responded, pulling me close and kissing me with unbridled passion. Our tongues met in a warm, wet dual as they massaged one another. I couldn't resist bringing my hands back to her naked breasts, squeezing them as we expressed our sibling love for one another. Breaking from our kiss, Katie urgently tugged my pants from my body until my cock sprang free. Its moment of freedom in the night air was short lived however, as it was soon engulfed in my sister's mouth. Bathing the shaft in spit, she ran her soft tongue all over my glands before plunging down on my throbbing rod. I could only close my eyes and groan as my world shrank to her warm, wet mouth on my cock. Coming up for a breath, sis returned to licking the head of my cock, making it twitch in expectation, before taking it deep into her mouth once more. This time she slid her lips along my shaft several times before relaxing and taking me down to her throat until my balls rested against her chin. The feel of her clenching throat around my member made me come close to orgasm, the rippling of her vocal cords incredible on my sensitive prick. With a pop and a gasp for air Katie pull back off me before kissing my mouth with incredible force. After an immeasurable time lost in her kiss, I helped her pull the soaked panties off her long, slender legs, leaving them in a bundle on the floor. Unwilling to wait a minute longer, I guided her over the hand brake and onto my seat, planting her on my lap facing the big screen outside. Racking the seat back gave us sufficient room to position the head of my phallus and the entrance to her pussy. I teased her briefly with the head of my member on her clit, before plunging down to leave her seated on my lap, her skirt covering both our crotches, hiding the wondrous sight beneath its thin fabric. With my cock filling her completely, and my balls pressed against her sensitive clit, I reached round her body to grasp her swinging breasts. Using them as leverage I started to move within my sister's tight tunnel, her velvety walls encasing me in a loving embrace. Our moans coupled with the sounds of our humping were making the movie inaudible as I slid in and out of her receptive pussy with ever increasing speed. With a final squeeze, my hands slid down her still clothed form till they were under her skirt, gripping her toned ass cheeks. Holding Katie's butt in both hands I could control her every movement on my shaft. I would lift her until only the my blood filled head remained lodged in her body, before plunging her back down, our thighs connecting with a slap. We repeated this process over and over, interrupting only long enough for sis to rotate her hips with me buried to the hilt, my rod exploring every nook and cranny of her amazing pussy. I much as I wished too, I could not keep up this rigorous lovemaking forever. Feeling the first telltale signs of approaching orgasm I reached round Katie's body, searching out her clitoris and rubbed it hard. With her inner folds beginning to ripple along the length of my shaft I sped up my thrusts into her wetness. My ass was coming off the seat on every up stroke, sis's head nearly hitting the roof with the force of my penetrations. My climax overcame me; with a bestial roar of passion I buried myself in Katie's body before exploding. The feeling of my cum jetting forth to splash against her inner walls, combined with my fingers on her clit, sent her over with me. My sister's cry of passion matched mine, as we died the small death together. I came back to this reality to find Katie leaning over the steering wheel, her breasts pressed against the cool black rubber. My softening cock was still inside her leaking pussy, our mixed love juices escaping around it to run down onto the seat. Looking out through the windscreen I noticed the credits to the film neither of us had watched the slightest moment of were rolling. Lifting the sated girl from my lap I guided her back onto her own seat and strapped her in. She instantly spread her legs wide and dipped her fingers into her well-fucked pussy. As I watched Katie brought the cum-covered digits to her mouth and sucked them clean. She moaned in satisfaction before turning to me and saying "you taste good big brother, thanks for a fun night". My only response was a wide grin that lasted the entire drive home. I'm sure I was still smiling as I quietly kissed my sister goodnight and snuck into bed, neither of us wanting to wake our sleeping parents while smelling of sex. This morning I awoke with aching muscles from last nights adventure and a hard on that could drill stone. Padding down the hall to the bathroom in my boxers I noticed Katie's door was still closed. Our parents' door however was open, revealing a made bed and no sign of the oldies. I stared blankly for several moments before remembering that they had told us last night that they were going to visit friends for the day. Curiosity sated, I made my way to the shower, turning it on and feeling the tension ease from my muscles as the warm water smashed against my skin. Coming back to the present, I turned off the now cooling shower and dried myself carelessly with my towel. Wrapping it around my waist I ran my fingers through my hair to give it a rough and ready comb, before stepping out into the hall. I was padding back towards my room when I heard a sound emanating from Katie's room that stopped me dead in my tracks. The sound was one I knew all to well, my sister's signature moan of extreme pleasure. As a stepped closer to the door I heard another sound, a low mechanical buzz that I was hard pressed to place. The volume of this strange sound pulsed, loud to quite and back again, in a rhythmic manner. My curiosity demanded that I ease open the door to see what lay beyond. The sight that greeted my gaze left me too stunned to move. Kneeling naked on her bed, facing away from me with her face pressed into a pillow, was my little sister. Protruding from her tight anal sphincter was the end of her favorite butt plug; I knew from experience that it was wider than my cock, and nearly as long. Now it was buried inside Kate's ass, stretching her dark passage wide. Lowering my eyes slightly I found the source of the buzzing sound, a vibrator in the shape of an engorged penis was gripped tightly in sis's hand as she fucked herself furiously. The sound would mute as it plunged inside her body, queuing a loud moan from Katie, before rising in volume once more as she pulled it from her swollen pussy lips. Dropping the towel from around my waist I stepped close to the bed, my erection standing proud. An evil grin stole over my features as I raised one open hand high, bringing it down on her raised buttocks with a crack. A shocked squeal split the air as Katie's head jerked up from the pillow, her cry of protest cut short by the sight if my ready cock near her face. The swollen shaft was throbbing in expectation as I offered it to my sister's lips. Without a word Katie took my cock in her warm mouth, sucking my clean cock hard as she re-started her rhythm with the vibrator. "You're such a naughty little slut sis" was all I could say as she moved down to bath my balls in spit before sucking my rod deep into her mouth once more. Meeting my eye she gave me a sly wink before concentrating on the warm flesh in her mouth and the combined sensations emanating from her pussy and ass. Thrusting into her hot little mouth, I reached down her body, past her white cheeks now red with my handprint, to grasp the end of the plug in her ass. Gauging her rhythm, I began wiggling it inside her backdoor as she continued to thrust the vibrating toy into herself. This extra stimulation made Kate groan from deep within her body. Her throat muscles rippled around my shaft as she moaned her pleasure, my gasp of pleasure filling the room as the vibration heightened my sensations. The smell of Katie's excitement filling my mind drove me to pull my length from her mouth with an erotic slurping sound. Stepping up onto the bed I grasped her hand holding the vibrator and pulled it from her body. My little sister moaned out a complaint as I switched it off, the room suddenly falling silent after the endless buzzing. The fake phallus appeared wet and glistening with a thick coating of love juice as I moved it to her mouth. Her complaints ended abruptly as the head touched her soft lips, her mouth automatically opening wide to accept the fake cock. Her beautiful face expressed nothing but satisfaction at the taste of her own pussy juices. Releasing her hand to thrust the vibrator into her own mouth, I watched in awe as she practiced all her oral skills before me. Bringing my attention back to the gorgeous upraised ass before me, I could not resist diving in to taste the sweet nectar gushing from Katie's pussy. Burying my tongue inside her slit, I drank her juices as though dying of thirst, my hands spreading her nether lips wide. My nose pressed against the plug protruding from sis's ass as I straightened my tongue and began thrusting into her vaginal opening. I heard Katie pull the dildo from her mouth so she could moan breathlessly in time with my tongue's ministrations. My thumb found her hard little nub and massaged it hard as her body began to shake with passion. Her body bucked fiercely when I grasped the plug in the ass and moved it within her body in time with my tongue and thumb's movements. The toy's small motions stretching her sphincter before my eyes' captivated me, a small part of my brain found time to be amazed that my sister's little body could fit so much inside it. Her white knuckles held the sheets in a death grip as she through her head back in a cascade of blonde curls and screamed her orgasm to the world. Katie's girl cum flooded me mouth as she thrust back onto my face, her body completely beyond her control as she experienced a mind-blowing climax. Lapping at her wetness with long strokes of my tongue I waited until sis had slumped forward onto the pillow before making my move. Kneeling quickly, I positioned my lance at her still pulsing entrance and thrust forward. My cock slipped into her soaked tunnel with ease as I buried myself completely in one long stroke. The heat of her body was a furnace as I felt the aftershocks of her orgasm around my shaft, her walls rippling at random intervals. The plug in her ass contracted the passage to make her even tighter than normal. My hands grasped her hips as I started to pound into my sister's pliant body, my crotch banging against the butt plug with every stroke. This fresh assault sent Katie over the edge again, her back arching as she experienced her second crashing orgasm in as many minutes. I gave her no respite this time, my hands finding her breasts and pulling her torso vertical. Her head lolled back against me as I continued to plunge into her clenching tunnel. Katie seemed to have ascended to another plane as I kissed her neck and kneaded her soft orbs. The slapping of our bodies joining filled the whole house as she slowly came back to reality. Turning her head to kiss me hard on the lips, my little sister moaned out the words I love to hear: "fuck my ass big brother". But it was her next statement that nearly sent me to nirvana on the spot: "I want you to cum on my face. Make sis into your dirty little slut". I covered my shock at my parents little angel's words by kissing her with unrestrained passion. Our tongues found each other and commenced their now familiar duel as I slowly withdrew from her gushing pussy. Her nether lips released my organ reluctantly as it slid down her wet slit to rest against her sensitive clit. Breaking from our kiss a gently pushed Katie down onto all fours again so I had ready access to her glorious posterior. Spreading her ass with one hand I gripped the base of the plug with the other. With gentle yet firm force I slowly pulled it free, her tight ring of muscle distending as it tried to hold onto its prize. Finally the sphincter relented and gave up the plug, sis's asshole gaping obscenely for a moment before winking closed. Placing the toy to one side, I moved in to lick my little sister's tender little star. Her moans reaching new heights as she felt my wet tongue probing her most private place. I explored her crinkled ring of flesh before trying to work my tongue inside her body, my saliva coating her in readiness for the next step in our lovemaking. Sensing her need for a more serious penetration, I moved to position my cock at the entrance to her backdoor. With gentle pressure the head popped inside the opening, the combined effects of my saliva and Katie's copious pussy juice on my cock making the passage nice and slick. The results of her recent stretching at the hands of the plug were clearly evident, my shaft burying to the hilt with amazing ease. Katie's quiet whimpers changed to fully-fledged moans of passion as she felt my heavy balls slap against her soaked pussy. We stayed motionless, with me buried as deep as possible inside her body for several moments, each of us savoring the sensations. Finally Katie wanted more; I watched as she reached back to grip an ass cheek in each of her petite hands and pulled them wide. I took this silent offer gratefully; my hips rocking backwards till just the head of my rod remained inside her body, before pushing forward smoothly. When my hips reached her butt cheeks once again I pulled back to repeat the process, only this time with more speed. We quickly established a wonderful harmony of motion as Katie's rocking body matched my rapid thrusts. The slapping of my churning balls against her wet slit filled the room as I pounded my little sister's ass without mercy. Raising her head sis gasped out that her poor knees were beginning to ache. Reluctantly I withdrew from Katie's sucking ass, her usually tight opening now open wide. I could not resist dripping a mouthful of spit into her dark abyss before helping her roll over onto her back. My beautiful little sister looked angelic with her golden locks spread on the pillow around her. While her flushed face displayed nothing but wanton lust. Her young firm breasts stood proud as I pushed her legs together and lifted them up high. Katie hugged her stiff legs to herself as I once again buried myself in her glorious butt. This position allowed us to kiss fiercely as I buggered her with long swift strokes. Her anal passage clamped around me as sis tightened her inner muscles, each contraction sending me closer to my long awaited release. My Naughty Sister Ch. 05 Spying the abandoned vibrator lying near us I snatched it up in my fist. With a quick flick of the switch in the base it sprang to life once more, it's buzzing nearly drowned out by our moans. Bringing it into contact with Katie's protruding clit brought instant results, her body jolted as though electrified as her mouth fell open in a silent scream. Her eyes momentarily opened wide in shock before once again clamping shut as another orgasm burst forth from deep within her. I held the vibrating toy firmly against her bucking crotch as she rode the waves of pleasure. Her ass held me in a vice-like grip as she thrashed beneath me, her head rocking from side to side as the sensations overwhelmed her. The magnificent sight before me, combined with the sensations emanating from my cock, brought me to the boil. Pulling from her ravaged asshole, I allowed her legs to slump to the bed before moving to straddle her chest. My hand gripped my shaft and stroked quickly as Katie lay before me with her eyes closed and mouth half open, gasping for air. With a yell of triumph I came, the spurts of white semen finding my little sister's pretty face with unerring accuracy. My amazing orgasm seemed to go on and on as my balls drained onto the moaning Katie. Her face becoming completely coated by the enormous volume of sperm my balls had produced during our long session. Her hand reached up to take the place of mine as she gently stroked the last few drops of my seed from me. Her other hand cupped my swinging testicles as she opened her eyes to look deep into mine. I remained captivated as her tongue came forth to lick up every trace of my cum that was located within range. Swallowing my offering she moaned in satisfaction before taking the head of my cock in her mouth and sucking me clean. The feeling of her hot mouth on my super-sensitive prick made me see stars. Releasing my cock moments before I felt sure I would pass out, Katie's goo-covered face split into a wide if somewhat exhausted grin. My smile matched hers as she blew me a kiss and whispered "thank you, big brother."
