Melissa turned the corner and emerged, finally, into arrivals. At midday there was a smattering of people waiting on friends and family; not quite a crowd. She stopped for a moment and scanned the faces, the variations in tone bewildering her slightly after spending so long away from home, the longest she had been in her short life. Yet she soon found the one face she was looking for, the one that was already smiling back at her, and Melissa’s heart started beating so fast that it was as if it was as if she noticed having it for the first time
Claire pushed herself off the pillar she had been reclining against after returning Melissa’s shy smile with her own confident grin. Today would be a good day, she thought, as she gently strolled up to the gate to meet her fine young lover. A junior broker at a leading city firm, Claire was only 23 herself, but Melissa was a mere 18 years of age, just young enough, still, to wear a schoolgirl’s uniform. And Melissa had of course obliged her request to wear it today, Claire thought with satisfaction, running her eyes up the girl’s body lavasciously, with neither concealment nor shame. Melissa’s shiny blonde hair was tied up in perfect pigtails, and her wide eyes, further defined with dark liner, stared back at claire as her lips curled around the long pink nail that she was gently chewing. The schoolgirl’s slim body was perfect, with a tight white shirt wrapped around those hard, medium-sized tits, several buttons open at the top to leave a hint of cleavage showing, and her tie dangling loosely around her neck. Melissa’s lower half began with a navy-blue pleated mini-skirt, from which her long, slim legs rapidly emerged, bare until they entered white pull-up socks that extended up above her knees. One calf was held cutely behind the other, and both led down to petit feet encased in girlish leather shoes with a slight heel. Yes, Claire thought, Missy was a truly gorgeous number, especially so at this moment – and Missy was hers.
Melissa was still so caught up in the moment that she had forgotten to move, at least until Claire began advancing up to the gate herself. After a month of nothing but photos and imagination, Melissa’s lover, at all times a thing of beauty, had never looked more stunning. Claire’s skin was paler than Melissa’s, almost white, yet her long hair, which she now wore untied, was raven black. Her smile was accentuated by deep red lipstick, and she wore a black choker around her neck. Beneath, Claire’s taut body and large breasts were defined by a tight, black leather evening dress. Her perfect legs extended beneath, through satin garter stockings of the same shade, into the highest of patent leather stilettos, which did nothing to impair Claire’s confident stride. Melissa gulped and walking forward herself managed to meet Claire just a few feet outside the gate.
The two girls embraced tightly without a word, and then their lips met, and then their tongues. Melissa felt the comfort she had too long sought as Claire pushed hers into the younger girl’s mouth, and a second wave of love and lust washed across her as she tasted a dark, earthy flavour already on it, leaving Melissa wildly rubbing her own tongue up against in hopes of finding more. When Claire finally broke the kiss, she continued staring into Melissa’s eyes as a strand of brownish saliva extended between them. Smiling naughtily, she said, “Welcome back, little sis!”
***
They sat on the back seats of a taxi heading home. Claire had sprung for a special cab with shaded windows, and she sat in the back-left seat, with her sister in the middle. They had been apart for far too long to waste any time away from each other now.
Many sisters are close and loving, but Claire and Melissa were far closer than most. Four years back, their parents died in a traffic accident, leaving the younger Melissa especially distraught. Claire assumed the role not only of an older sister, but a guardian to the younger girl, and though Melissa could not be said to have fully recovered, Claire’s dutiful love had brought her spirits back sooner than either would have thought possible. This trip, Melissa’s first away from home alone since their parents’ passing, had been suggested by Claire as a part of that recovery.
“So, how was Australia, sweetest?”, asked Claire. Melissa’s face lit up again. “Sunny! Very sunny! A lot of animals… And, what you said before, very…conservationist…?” Claire tutted and giggled. “Very *conservative*, Missy. *Conservative*. You didn’t…mention anything to cousin Ruth, did you?” It was Melissa’s turn to laugh. “No, no! I think she’d have enough of a problem with me having a boyfriend at my age…she looked so relieved when I told her I didn’t!” “Oh dear!”
The girls giggled along, swapping stories for some time until Claire broached another subject: “Well, how was the flight?” “Oh, it was fine, they really took care of me. But the meals were kind of, um…” Melissa’s stomach cut in with a deep rumble, as if to finish her point. “Maybe I shouldn’t have picked the seafood…”, she continued sheepishly. “Didn’t use the loo?”, asked Claire, a little concerned. “I…could have, I guess…”, explained Melissa. “It’s just…it’s been so long, I hoped we could…y’know…straight away…” She turned to Claire with wide, sweet eyes that nonetheless lacked a certain innocence. “Everything in Ruth and Matt’s house was so…neat and tidy…and quiet… I couldn’t even touch myself, let alone…”
Claire reached her arm around her sister’s shoulders and smiled at her. “Shhh…of course we can, sweetest. Of course.” Checking that the partition window was blocking the driver’s view, she placed her second hand on Melissa’s taut tummy. “I’ve missed you so much, Claire”, Melissa whimpered. “I’ve missed *us*. How we smell, how we…taste… Everything.” “As I have missed you, Missy”, her sister replied, fingers creeping down the spotless white shirt, across that little pleated skirt.
“Oh, Claire…”, sighed Melissa, “please, please…” She began fumbling with the buckle of her seatbelt, desperate to allow her sister access to her sweltering girlhood. “No, sweetest”, responded Claire, pushing Melissa’s hand away, all stern guardian for a moment. “Remember what happened to Mum and Dad…” A little flash of fear passed through the younger sister’s eyes, and she leaned in to Claire even more closely. “I…I’m sorry…I never want to lose you!” The elder sister softened again. “I’m never going to let that happen”, she promised, gently kissing Melissa’s neck as her hand returned to its nether exploration.
Claire’s fingers passed under Melissa’s navy skirt, and clambered along the leather car seat toward the younger girl’s gusset. Reaching out, Claire embraced the silky, wettening warmth of her sister’s panty-clad vulva, eliciting a small moan with the contact. She softly ran her fingertips up the fabric obscuring Melissa’s labia, towards the hood of her clitoris, juices soaking through where she applied pressure. Her little sister’s clit was already hard, and needed little coaxing to reveal, even through the material. Claire smiled as she began to massage it with her thumb, while lowering the long, dark fingernail of her index…
Melissa truly began to ride the waves of her pleasure, sluttishly twisting a nipple through her school shirt, while chewing a pink fingernail to keep from crying out enough to alert the driver. All thoughts of fear or danger, or even time, were again lost to her as her beloved sister worked magic on her pulsing crotch. Then, just as she was becoming accustomed to this pleasurable rhythm and seeking to accelerate it, Claire paused in making love to her neck, and whispered in her ear: “Relax, Missy, you’re home. Let go…” And on that final beat, her pleasure was punctuated by a sharp, burning shock of feeling, and a sudden need to release her bladder.
Claire began to finger Melissa harder just as she drove the tip of her fingernail through the fabric of her sister’s panties and into her unaware urethra. The unexpected interplay with one of Missy’s most sensitive spots was a risk, but she needed to finish the girl off before the taxi stopped, exposing them. Claire watched knowingly as first pure shock passed through her sister’s eyes, and then release, as the increasingly intense manipulations of her clit broke pain into obvious pleasure…and her bladder opened…
Melissa was overwhelmed by a small, sharp urethral orgasm that seemed to have come out of nowhere, melting away the initial pain. Her sex was a mass of heat and liquid, as juices sprayed out of her…wait, was that…? “Uh…c-cumming, oh, cumming PISS! Ooh!” She continued writhing in pleasure as several golden jets shot out, splattering the leather partition in front with urine, before collapsing back against her seat in a ruddy mess of perspiration. It was only then that she realised the taxi had come to a stop.
“Everything okay back there?”, asked the taxi driver, opening the partition window. Claire had already brought herself up there to block the view. “Well”, she said, keeping an admirably straight face, “I’m afraid my poor little sister has had a bit of an…accident. Terribly sudden. Awful flight, you know.” The man sighed. “I have to clean those seats myself, you realise…” “I quite understand. Perhaps a small tip would show our sympathies. Perhaps…triple the journey fee?” The driver shrugged obstinately, and Claire closed the window again.
“Are we…in trouble…?”, Melissa asked her, worry setting in as her afterglow drained. “Oh, Missy,” comforted Claire. “Did the girls from Piss Sluts Gone Cray Cray VII get into trouble? And that was an entire villa. Don’t worry about a thing: your big sis is going to take care of this.” Claire fished around in her pocket for something, and pressed it into Melissa’s small, sweating palm. “Here’s the key so you can let yourself in and get cleaned up. I’ll bring in the rest of your stuff. Call me up when you’re ready to…get dirty again.” Claire kissed the top of Melissa’s head before watching her scamper off into the house.
***
A short time later, Claire entered the darkness of her sister’s room, shadows interrupted only by light from the occasional scented candle against a wall or shelf. Their frail luminescence revealed Melissa lying back on her bed. Her skin was bare other than her frilly white lingerie, yet Claire noticed with surprise that while her sister had otherwise stripped, her footwear had become less revealing. Melissa’s long legs were crossed and clad in black, knee-high lace-up trainer boots, gently waving in the air behind her, as if to welcome Claire in.
“Well, aren’t those sweet?”, said Claire, sitting down on the side of Melissa’s bed, and gently beginning to stroke her sister’s shoulders and golden hair. “Sweet?”, Melissa giggled. “That’s not…quite what I had in mind, but…” “Shhh..”, Claire answered, slowly but deliberately placing her forefinger against her sister’s lips. “Everything about you will always be sweet to me. Speaking of which…” Claire’s clear voice trailed off as she climbed on the bed and brought her head between her sister’s legs.
Amongst the ambient scent of the candles scattered around the room, Claire had at first thought she had smelled a darker undercurrent in here, though it always evaded a clear fix from her senses whenever she became aware of it. At the top of the bed, Melissa’s perfume had overwhelmed the odour, pushing it out of Claire’s mind, but down at the bottom it returned, and with greater strength. Yes, thought Claire: it was unmistakably the scent of her little sister’s warm, wet girlshit…but where? Claire brought her head forward in search, lightly sniffing Melissa’s crotch before giving her sister’s panty-clad cunt an inquisitively lick.
Melissa, seeing that Claire had begun to understand the game, giggled again, whispered, “Sorry, not quite!”, and again began to gently cycle her legs in her excitement, raising her perfect buttocks a little off the bed. She had yet to change her knickers since the most unfortunate incident in the taxi, and there were subtle skidmarks on their middle and back, even in the dim light almost as evident from outside as the piss-stains along the front.
Claire felt her heartbeat accelerating as her sister revealed the first traces of her crap, and found herself diving towards Melissa’s ass, lavasciously licking at the fabric of her panties, as if trying to extract the small remnants of her waste out through it and onto her tongue. Yet there was no telltale brown lump clinging to Melissa’s cheeks. “Not there yet, but you’re getting warmer!” she heard Melissa call. Indeed, Claire thought, as she brought the fingertips of her right hand down to rest on her rapidly-engorging clit, I am.
Melissa saw her sister bring her head up from her crotch with a slightly confused expression, which could not help but provoke another fit of giggles from her. She again cycled her legs with gentle mirth, her right calf falling to rest on her sister’s shoulder. Claire’s puzzlement seemed to persist for just a moment longer, after which a clear look of recognition passed the older girl’s face, before it turned towards the boot. Melissa smiled.
Oh, you horny, horny bitch, Claire thought. How I love you so. The scent was still subtle, but so much stronger around Melissa’s legs. There could be no mistake. Her hands shaking just a little, Claire brought Melissa’s right calf down carefully onto the bed, and began hurriedly unlacing the elegant denim boot encasing it. She untied the knot, hands shaking slightly like a girl opening her most-anticipated birthday present, and gently, gently slid it off.
From beneath the browned tongue of Melissa’s boot, the full putrescence of what Missy had done was revealed to Claire. The sight and smell churned her stomach and burned her cunt. Her little sister’s long, slim leg was entirely coated from beneath the knee in sloppy crap. Melissa’s small foot slipped out with a wet pop, making it clear as mud that the crap was thickest the bottom; as the girl wriggled her filthy toes in the dim light, small lumps of faeces ran out from between them and off the tops of her pink-painted toenails.
“Surprise!”, Claire heard, but Melissa’s voice was somehow distant, and it barely registered. instead, her senses were overwhelmed by foul odors and, as soon as she could possibly manage it, fouler tastes. Claire lay down beside her sister, but in the opposite direction, her face aligned with Melissa’s deliciously browned toes. “Indeed, nothing could be sweeter…”, Claire told the teen temptress, lowering her face towards them. She paused briefly to inhale deeply, close to the source, before gingerly slipping out her tongue.
As its tip met the stained underside of Missy’s big toe, Claire got her first hit of the flavour: deep, earthy and foul. It chilled her as she continued to run her tongue slowly across the surface, while her sister wiggled and giggled. As Claire began cleaning the crevices between Melissa’s toes and where they met her sole, she found larger morsels of pure shit and even undigested kernels of corn, either still warm from its emergence, or reheated and marinaded in sweat, deep within her sister’s boots. The abhorrent tastes released as she chewed this recycled food and rolled it around her mouth were turning even her tested stomach, and she found herself drawn to self-pleasure merely to keep herself from vomiting. She slipped the ends of her fingers inside her panties, and began running her incipient wetness across her hardening clit.
Melissa, meanwhile, was excited both by the fecal odours exposed to air by the removal of her boot, and the gentle yet gross tongue-bath she was receiving from her sister. She had also begun reaching inside her underwear to explore her shaven slit, already slick with juices and piss. Gently frigging herself, she allowed her sister many minutes of reverie, occasionally playfully smearing her shit across across Claire’s lips with her toes and laughing. But when the crap was largely cleared from her foot, and Claire seemed to be fully aroused, she withdrew her legs.
“Dearest Claire, this little foot massage is all well and good, but I want something a bit more…I wanna be held by my big sister again…”, said Melissa, smiling shyly. Claire stopped touching herself and sat up. “Of course, Missy. I missed even your toes so much that I almost forgot about the rest of you! Very well, let’s have another look at what’s in your knickers…” “Um…Claire…I was thinking more of…do you think we could we have a…*shitstorm*…?” Melissa whispered the word, but emphatically, as she turned her eyes downwards, and her little face reddened. Claire drew breath, her heart beating faster, “…Sweetest, are you sure…?” The younger sister turned back to face her, conviction in her voice: “Yes, oh yes, I’m sure. It’s…all I’ve thought above these past weeks. *You’re* all I’ve thought about.” Claire responded with a fond, reassuring smile, before leaning over and drizzling saliva and the remnants of her sister’s own fecal matter between Melissa’s pink lips, before dancing tongues with her through a haze of dirt.
When the girls were done with their last moments of foreplay, Claire began to remove her clothes with some urgency. Melissa, who had merely to remove her left boot and dishevelled knickers to prepare, watched excitedly, lightly rubbing her hardening nipples through her bra. Claire elegantly unzipped her dress and stepped out, revealing her firm, round tits and taut stomach to the dim candlelight. She smoothly pulled her increasingly sodden panties down her long, bestockinged legs, and lightly flicked them away as she stepped out of her stilettos, leaving her wearing nothing but pantyhose and her trademark choker. She sat with her arms around her beloved sister, sharing several more deep and lightly brown kisses as they prepared for the main event.
“Okay, are you ready, little one?”, said Claire, and on seeing her sister nod, “Let’s roll over.” Both girls moved fully onto the bed, embracing again but this time with their legs, as they assumed a scissoring stance. Claire, her head at the base of the bed as Melissa reclined against the pillows asked teasingly, “You do still have some left in you, don’t you?” “Oh, enough to fill you up and then some!”, purred her sister in response. They twisted and fumbled with the slight awkwardness of lovers parted for a time, but quickly managed to recover and align themselves for their most vile, and yet somehow most loving of acts.
Claire began first, having yet to feel release today, squeezing out rank winds across her sister’s vulva. As Melissa began trembling in anticipation and some still vestige of visceral, unconquered horror, Claire soothed her with gentle kissing and stroking of her thighs. “I do this because I love you”, she said, as the tip of a large, solid turd emerged from her bowels. Melissa whimpered at the feel of her big sis’s log licking the nub of her clitoris, leaving a stinking, stinging trail of caustic waste across the entrance to her teenage womb. This was so wrong, and yet so, so deeply needed.
The younger girl’s mind returned, as always, to their first experience, her wonder at how the ‘sex’ she learned about at school could be conducted when neither partner had a penis – how girls could find things, parts of themselves, with which to fill each other…? “Do you trust me?”, Claire asked her, just like always. Just the same as on that first night she had come to her big sister’s bed for solace – the night of their parents’ funeral. “Uuu…hhu…yes. I love you sis!”, gasped Melissa, finding the only answer in this moment, opening both mind and body as the ripe turd slithered into her cunt.
“This is my gift to you; this is my love”, whispered Claire to the sister she had raised into both a beautiful, charming woman, and a base, depraved sex toy. Melissa thought she came up with the idea, of course – Claire doubted it would ever have worked if she hadn’t – but Claire had planted it, subtly, in conversations sparked by natural sexual curiosity: “This is how us women can make love. Now we’re by ourselves. Now we don’t have anyone to depend on but each other.” On that first night she had comforted her sister – and herself – by bringing to life the dreams and nightmares she saw every night after night slumped asleep in front of her computer, searching for stranger and darker things within and without. She squeezed off her turd as it packed Missy’s little cunt with filth.
Melissa ran her fingers across her shitty clitoris as the aroma reached her, filling her, trance-like, with the full realisation of the warm mass that pleasured her vaginal walls, smearing their little pink surfaces with filthy crap. The turd extended out a little from her entrance as she squeezed her cunt muscles around it, oozing brown-tinged cum out across her labia. Warmer, more organic than a dildo, it almost itched pleasurably as toxic grit was rubbed deep into her folds.
“Missy…?”, asked Claire, nibbling at the girl’s heels to bring her around. “…uhh…” “If you would do the honours…” “Oh…of course!” The sisters rolled around slightly to realign themselves, each small movement driving Melissa a little crazier as the shit touched new places within her. After a few moments, Melissa got her rosebud over Claire’s pussy, and, as her sister held her cuntal lips apart, began to evacuate her bowels.
Shitting felt exquisite as fecal matter on both sides of the so-thin wall between her pussy and rectum pushed against it. Melissa was so caught up in the feeling that it wasn’t until she heard her sister’s shriek of laughter that she realised there was much more than just solid waste this time. “Diarrhea?”, laughed Claire as the first lumpy splatters spluttered out across the neatly-trimmed hairs of her bush, “Oh, you shouldn’t have!” “Uh, sorry. That airplane food, huh? Uh, mhm…”, returned Melissa, beginning to spray sloppy, wet girlscat into her big sister’s waiting cunt.
Claire was intoxicated now, flicking her slippery clit as Melissa’s goopey crap poured into her lovehole. Its liquid warmth was almost like a douche, but she shuddered in mad lust to consider that rather than purifying water, she was willingly befouling herself with putrid wastes. Yes, she was taking the most intimate part of herself, what God had intended as a newborn child’s innocent passage into this world, and turning it into a toilet for no higher reason than her own sick pleasure. As the irregular flow from her sister’s anus slowed to a trickle, leaving her vaginal canal a stagnant pool of fecal filth, Melissa pulled away, allowing Claire’s fingertips into her cunt to spread the browning outside. Droplets of wet shit glistened on her trimmed pubes as she brought tiny solid lumps upwards; lumpy strings of undigested onion skin to crown the nipples atop her breasts.
“Sweetest”, Claire said breathily, “you wouldn’t believe how this feels… We should have tried diarrhea before! Ah, but now I need the taste again…” “Uh…uh…yes, sis. I wanna try it…” Claire disentangled her long legs from her sister’s, and gently pulled the overwhelmed Missy over her. As Melissa’s shit-packed cunt came into view above her, and the wicked aroma of her own turd became intense, Claire felt re-energised, and her sister’s excitement at coming face-to-face with her sloppy, stinking teenshit smeared across a gorgeous young pussy was just as evident. “Oh, holy crap!”
“Eat up, little one, it’s good for you!”, taunted Claire, before rapidly laying into the shaven teen slit before her. Skidmarks ran out across her sister’s vulva in all directions, and the smell and taste of salivating twat mixed with her own decaying crap overwhelmed her as she ran her tongue towards Melissa’s toxified clitoris.
“Oh…oh, yeah, Claire, that’s it….RIGHT there…”, purred Melissa in response to the light touch of Claire’s skillful tongue. The younger sister began to breathe deeper, her stomach revolting as she inhaled putrid fumes from the diarrhea-packed snatch in front of her. “Lick my shitty clit, Claire…uh…oh, please eat my shitty cunt out!”
Claire felt Melissa’s cunny begin to rhythmically squeeze around the firm log inside it, and continued her foul love-making, slipping first her right index finger in alongside it, and then her middle. Her fingertips ran across the slick, dirtied vaginal walls around her sister’s g-spot, but the stodgy turd felt against the tops of her fingers blocked her attempt to accurately finger that special place. In response, she thrust her fingers more harshly and deeply into the fudge, cutting at it with her fingernails. She brought her mouth gently down from its clitoral duties, and wrapped it around the base of her fingers, using her tongue to draw out detached lumps of her warm shit, marinaded in girlcum. Crap drizzled into her long, black hair as she worked hungrily to draw tiny, waxy lumps into her mouth, and roll them around with her tongue, savouring the bitterness.
Melissa was gasping at the feel of those shitty, gritty fingertips dancing around so close to her pleasure spot. Her cunt muscles pulled tight around the stool within her, squeezing out shit juices and hastening the descent of baby turds into her sister’s waiting mouth. But she knew she needed something more to take her towards orgasm, and besides, why should she have all the fun? Claire’s raven cunt lie just before her, and it ached for the touch of her loving tongue just as surely as she craved to taste the feculent horrors within. Yet the odor of the yellowed, rejected seafood that made up the solids in her diarrhea was grotesque beyond even anything she had yet experienced in her descent into the basest toilet sex.
Steeling her stomach for contact recalled Melissa’s early months of experimentation with her sister, in which they had trained themselves to contain vomiting, first from only a few seconds of taste. Claire assured her that these skills were vital for proper lovemaking, real adulthood: “You love me, don’t you?”, Claire had asked. “O…of course!”, Melissa returned, instinctively clutching the arm of the only family left to her. “Truly? Absolutely?”, Claire countered with a firm smile. “Yes!” “But that means you need to love all of me. Without and within. Not just what’s on the surface, but what’s inside.” “What’s…inside? You mean…?” “Yes, that is true love, sweetest. It won’t be easy, but this will bring us pleasure for the rest of our lives. Now, let’s try again”, Claire had concluded, bringing another smeared finger to Melissa’s tear-stained lips. And she was right. Learning to hold it down was hard, but the intense highs shitsex brought to their relationship had bound them closer even than Melissa could have imagined back then. Steadily breathing in the repugnant scent, feeling perverse ecstasy spark between the vibrations in her quivering quim and shuddering stomach, she prepared herself. She’d make her big sister proud once again.
Oh, but it was horrible. Terrible. Wonderful. Melissa’s tongue swam through the putrid grease with which she had defiled her own sister’s womb. The acidic broth that even her bowels had seen fit to reject flowed into her mouth like honey, as the loving touch of her big sis on her own befouled cunt cross-wired parts of her brain that should never have met: revulsion and love, beauty and horror. She sipped and slurped, filling her aching mouth with poisons, and drizzling them back across Claire’s taut stomach and trimmed raven bush. Then she dove back in for more, letting her tongue search the depths of her sister’s folds for rotten morsels.
Claire began to feel the touches of her sister’s tongue inside her at the moment she bit open her first prized, rancid nugget. The brushes against her shit-slick walls were so gentle, yet formed a perfect counterpoint to the angry, cutting flavours of her turd, formed, as she recalled, from a fine roast lunch. The parts that had survived the journey through her intestines were no longer so fine, having been reduced to scraggly rinds of decaying fat and roughage. She eagerly ran them around her pallet, savouring and then choking them down, tingling, smiling as another tongue lovingly ate from her. After swallowing the first round of her rich, womanly crap, Claire returned with a renewed desire for more, reaching her fingers and tongue together into the younger girl’s cunt, now a disfigured, gaping brown hole, leaking caustic waste in all directions.
Melissa, meanwhile, was far down her depraved path to orgasm, senses overwhelmed by foulness, when Claire began her second, deeper assault. Whether the warm, soft probes that inflamed her diseased puss were fingers, tongues or merely crumbling lumps of shit, she had no way of knowing. All she knew now was that it had become a conduit of pure pleasure, one that somehow made the repugnant broth drooling down her face from between her slack lips not merely bearable, but darkly delicious. Riding the wave of ecstasy passing through her almost to its peak, she thrashed her tongue wildly at the fountain of filth that her sister’s vagina had become, as stocking-clad thighs wrapped themselves around her head, pulling her in deeper. Ragged taunts encouraged her decadent exploration just as surely as the intense finger-fucking she was receiving: “That’s right bitch, drink your stinking diarrhea right out of me…! Goddamn, OH GodDAMN…I love you SO MUCH, you FUCKING little toilet-mouthed SHITWHORE!”
This sweet talk simply drove Melissa harder, ever harder…too hard. Just as her crisis approached, fighting to escape her pussy and run riot throughout her body, her tongue wandered across a dark little turdlette nestled in Claire’s innermost folds. Retrieving it, she bit without caution through its tough shell of compacted bowel fruit into the raw flesh of some diseased sea creature. This was the wonderful poison her body had attempted to flush from itself, *to deprive her of*? Even against the harsh backdrop of melted turds plastered across her gums and teeth, it was something incomparable, unholy. Her gag reflex kicked in immediately – as did the greatest orgasm of her life. Every nerve ending in her body was on fire, and she would have screamed uncontrollably if her mouth wasn’t spewing forth a waterfall of vomit. Simultaneously, her completely overloaded vulva simply lost control of its trembling, and an intense spray of deep golden piss burst out of her bladder, splattering her sister’s face, tits and hair with concentrated urine.
Claire, for her part, never felt her orgasm coming. She should have realised that even in her state of wild abandon, such a long build would have a heavy payoff coming, but she was just so entranced in fingering the intimate, rancid mess of a sexual organ she and her nasty little slut of a sister had created. The warning signs only appeared as Missy unexpectedly turned her open mouth into a urinal, washing down her delicious banquet of turds with dark, pungent pee. And just as Claire had processed that surprise, a second dark revelation hit as she felt a warm, lumpy liquid spew across her genitals, refilling her aching puss. Gasping, she turned her head downwards and looked between the cleavage of Melissa’s quivering tits. Even in the dim candlelight, she could clearly see what had happened from the white chunks of deep stomach vomit that were intermingling with her sister’s regurgitated shit, running between her legs and into her spasming cunt. Her…spasming…cunt, she thought briefly, God, what an ill little creature to react in this way; not to close its tiny mouth as septic poisons poured in, but somehow to eagerly open ever wider, as if to gorge on them… Lord, how utterly wrong this was….why? And then, as the chunks of vomit came to rest in the depths of her cervix, it happened, and she came and came and came.
In the depths of heaven, the heights of hell, Melissa gave in entirely to her pussy. Of course, she heard the garbled commands her sister yelled about licking “shitvomit out of her cunt” with her “little BITCH, little DAMNED toilet-paper tongue!”, amid a string of other obscenities, protestations of love, and implorations for God to forgive her. But it was her pussy that moved her tongue, her pussy that urged her to dine on more glorious filth, to fill the air she breathed and the tastes of her petite mouth with acidic lumps of undigested shit to feed her ungodly high. Her pussy, oh my, was it three, four fingers in her now, or an entire fist, scraping crap off her inner walls, churning it up inside her, pounding it deep towards her womb? It drove her onwards in her quest for depravity, sucking squelching, stinking fecal puke from Claire’s womanhood, splattering her girlish little blonde pigtails brown as they shook in ecstasy. Orgasm after orgasm rattled through her tiny, teenage body, as piss and cum exploded out of her cunt. As she passed out, lost in pleasure of this shitstorm, she knew it. This was true love, just like her sister said.
***
Claire held Melissa from behind in the silence of the night, feeling her breathe gently, inhaling all the scents of her body. Her sweetest was so tired out after their lovemaking that she wanted to sleep almost straight away. The clean-up could wait until tomorrow, and, besides, there was something very intimate, very romantic about lying together in their wastes, a filthy nest of their own creation. Still, something bothered Claire. Regret? Never. But perhaps what she had heard called…’guilt’?
“Missy, are you awake…?” But her sister’s oblivious snoozing answered the question for her. Never mind, that would have to wait, too. Still, the final test was a success: Missy was hers now, absolutely. Even more than before their brief separation, she accepted any suggestion, no matter how depraved, not only as normal, but pure and loving. The girl was even beginning to create her own kinky games. Yet, decadent as their relationship undoubtedly was, Claire truly cared for her sister as more than just a broken-in toilet fucktoy for bringing her sickest fantasies to life, as she always had. Melissa was an adult now, the same age Claire was when she made her first adult decision. She deserved to know.
She’d understand. Wouldn’t she? It would be hard, but … Missy had to realise that that bitch would never have let them have this. Was it even so unnatural for girls to see each other naked? Especially sisters? Yet even when they were children, Mother wouldn’t so much as let Claire be in the same room when Missy was going potty. And then when as a young teen, Claire was caught ‘practicing’ kissing on her sister, and was forbidden to touch her again, even to hold hands… That was the last straw. Oh yes, Mother had it coming. Daddy? Well, she had nothing against Daddy. Daddy was…collateral damage.
Claire had planned the crash with the meticulous diligence and precision that went into her every school project. She learned which parts of the Mercedes could be subtly altered within the bounds of normal manufacturing variation, which trace drugs would escape chemical analysis. Between her extensive research and icey intellect, by the time she executed her plan, she understood crime scene investigation better than any of the fools at the local constabulary ever would. ‘Cause of death: accident, due to driver’s misjudgement.’ She smiled at the memory. And if there had been suspicions of foul play? They would never have fallen on a grieving little daughter with a spotless record, now left to raise her even younger orphaned sister.
No, Claire felt no ‘guilt’ over their deaths. Nothing at all…except what she had taken from Missy. Seeing the tears run down her sister’s face that night, she almost confessed there and then. It was only the seeds she had already planted, the suggestions Missy thought she made herself, that kept the plan together. But now it was time to make things right. She’d understand, now, that the gains outweighed the losses, surely, surely they did…
“Uh…Claire, did you say something?”, mumbled Melissa, rolling over to face her big sis. Claire drew breath. “Missy! Yeah…. It’s about… It’s about Mum and Dad…” she choked out. As Melissa turned her little face quizzically in the dim light, Claire saw her baby sister nonchalantly lick a splash of her own feces from the corner of her mouth as if it were no different to chocolate, and, for no reason, shuddered. “Well, what is it? …Sis?” Claire looked Melissa deep in the eyes, and swallowed. “Uh…. I…. I….did….”, she stumbled, stopping as she realised there was wetness on her cheeks. “…miss them.” No more words would come.
Melissa stared back at her sister, and embraced her. “I understand,” said Melissa. “I miss them too. But I have you…my sweetest.” Claire sobbed gently as her sister’s tongue entered her, and deposited a loving gift of shit.
