Her plan was almost too perfect for words, excelling her usual brilliant standards by some distance! "Oh Rarity, you simply are a genius! What ever will you think of next?" the egotistical unicorn self-congratulating herself as she applied the finishing touches to her latest fashion creation. Whilst Pinkie Pie would be receiving the usual mundane party gifts of sweets, treats, toys and other knick-knacks to commemorate her birthday, Rarity had a present that would live long in the memory of the playful pink party pony. It was sure to be a huge success! A coy smirk spread across Rarity's pouting lips as she stepped away from her trusty sewing machine, awestruck at the beauty of her newest design and fully marveling the denim delight that had taken simply ages for her to painstakingly craft. "What mare could resist I ask you?" Rarity nonchalantly announced to her empty boutique as she allowed the coarse material to abrasively rub against her delicate snout, shivering in euphoria as she planted her sensitive sniffer directly against the seat of the denim jeans. "Oh my! So fresh, so fetching, so fabulous!" the seductive seamstress cheered as she continued to noisily huff in the alluring aroma of shear perfection, picturing Pinkie's plump posterior filling those tight and constricting jeans. Though it saddened Rarity slightly that she would have to part with such a perfect pair of jeans, that didn't deter her from trying them on herself. After all the hard work and effort that she had put in to crafting them, Rarity figured that it would be an absolute crime if she didn't grace those jeans with her own beautiful buttocks. A lady has to have some fun too right? That same nervous energy returned to Rarity as she grasped the waistband of the glorious garments, biting her bottom lip innocently as she hoisted the jeans high into the air to admire them. "Oh goodness, how in all of Equestria am I going to fit into these?" Rarity feigned her concerns before a mischievous grin lit up her pretty pony cheeks. Not being renowned for giving up quite so easily, Rarity proceeded to step into the pair of jeans before hiking them up just below her delectable derriere. There was no way at all that these jeans were going to comfortably accommodate Rarity's ample ass-cheeks, the waistband already tightly wrapping around her thighs and squeezing her legs together like a Boa Constrictor! Be that as it may, the persistent pony persevered as she clutched the waistband of the jeans tightly with her magic before attempting to cover her curvaceous cheeks with that delightful denim, allowing a few feminine grunts and unladylike expletives to escape her lips as the rough fabric was abrasively dragged across her doughy derriere. "A-A-Almost... there!" Rarity puffed and panted as she desperately tried to wiggle her flanks into the jeans, beads of sweat glistening upon her forehead as she refused to back-down from the challenge she had set herself. What seemed like an eternity had passed before the determined fashionista let out a triumphant squeal of joy followed by an exasperated gasp of exhaustion. Almost defying the laws of physics, Rarity had managed to squeeze her raunchy rump into that tight pair of jeans, the definition and contours of her generous glutes easily being displayed and flaunted by the gripping denim. The ivory unicorn had only just managed to do up the button at the top of the jeans, said button threatening to burst at any given moment! "P-P-Perhaps I should have *wheeze* made them a little l-l-looser" Rarity groaned as she struggled to even move, the tight waistband cutting into her tummy with each tiny step that she would take. Although the jeans were entirely impractical for modern-day usage, Rarity couldn't deny that she was getting a naughty kick out of having her figure strangled and constricted by the imprisoning garments. So much so in fact that her own pony tightness started to dribble and ooze her sacred, sticky secretions as she grasped a handful of her own bulging backside, imagining that she was gripping and grasping at a certain pink pony's pudgy posterior. Almost losing herself in her own imagination of sick and sordid fantasies, Rarity quickly snapped back into reality as a more pressing matter made itself known. Whether it was the unbelievably unforgiving grip of the jeans crushing and compacting her tummy or the incredibly large and generous breakfast that she had consumed earlier that morning, Rarity's guts gave an ominous grumble as the realization began to creep its way inside of her mind. Although Rarity's resolve was surprisingly strong, the naive mare was almost certain that she wouldn't be able to maintain the level of concentration required to stifle the sensation building up within her bowels. Even though she was all by herself within the confines and safety of her boutique, Rarity refused to succumb to such uncouth and uncivilized practices, trying her utmost best to keep a tight grip on her quivering ponut by clenching her shapely orbs together. "Not now Rarity, not like this!" she pleaded with herself before desperately fumbling with the button of the jeans, practically doing anything to relieve a bit of pressure from her swollen stomach. Alas, Rarity's best efforts to stave off her own flatulence had been for naught as the seamstress begrudgingly accepted the fact that there was nothing else she could do to prevent what was about to come. Her cheeks were already starting to redden with embarrassment as that bright burning blush erupted all over her face. Looking all around to make sure that she was definitely alone and that the coast was clear, Rarity slowly started to spread her legs before leaning forward slightly, patting her distended tummy as it ferociously growled back at her. The mare huffed in annoyance as she was resigned to the fact that she would have to submit to the natural yearning and urges of her body. Scrunching her eyes shut tightly, Rarity took in a deep breath before reaching behind herself, clutching her monumental mounds and spreading her cheeks slightly before focusing her fullest attentions on expelling the foulness that was pent up inside of her. Tensing up her stomach muscles, the ivory mare grunted and gasped as a pocket of putrid gas forcefully burst forth from her puffy ponut, impregnating the seat of those jeans with the hideously humid stench of her gruesome gas. Rarity even managed to let out a feeble yet pleasurable little squeal throughout the duration of her unladylike blast, unable to deny the fact that the stimulating sensation of her rim rippling freely was simply divine! "Oh my, that is vile! What is wrong with my poor tummy today?" Rarity casually commented, trying to convince herself that what she was doing was the height of bad manners and etiquette despite it feeling so... therapeutic! More gas was rapidly requesting for release as dear Rarity was powerless to prevent herself from appeasing her aching tummy, this time lowering her fantastic flank to the floor before letting out a monstrous bout of malodorous miasma, the bassy blast rebounding off of the floor and even echoing throughout the entire vicinity of Carousel Boutique! Rarity was indeed thankful that nopony was around to hear and more importantly, smell her callously cacophonous emissions. The fashionista frantically fanned a hand in front of her nose in a futile attempt to dissipate the concentrated evil radiating from her otherwise beautiful backside, a plethora of labored coughs erupting from the mare as she tried desperately to stomach the nauseatingly noxious aroma that she had previously pumped out! The inner turmoil inside of Rarity was huge as a hefty conflict was brewing inside of the usually calm and collected mare as she undoubtedly knew that her uncouth actions would be frowned upon by each and every one of her friends. Just the thought of anypony finding out about her brazen and delinquent act caused an impending sense of doom to swell and fester inside of the mare. However, the more she dwelled upon being discovered in such a compromising position, the more fascinated and intrigued she became until a naughty chill was sent coursing down her spine, not to mention a sudden rush tingling through her tender pony folds. To think that a unicorn of such high social status and detrimental importance to Equestria could be so downright crude was frankly unfathomable! Be that as it may, Rarity couldn't shake the fact that indulging in such purely perverse acts excited and invigorated her greatly! Perhaps there was indeed more than meets the eye to this complex and diverse pony? Perhaps... The flatulent fashionista stroked and caressed her bloated belly rhythmically, deciding that she simply must rid herself of the paint-peeling foulness that stirred inside of her groaning guts, even if that would result in successfully sullying the jeans that she had intended to give to Pinkie Pie. With a quiet nod to herself to confirm what she was about to do, the elegant equine slowly lowered herself to the floor before flipping over onto her back. An intense expression of purest concentration filled Rarity's face as she pulled her legs closer to her chest, priming her pungently potent ponut very much like Pinkie Pie's trusty party cannon. With a final chew of her bottom lip, Rarity squeezed her plump pony cheeks together tightly before giving permission for the swirling and spiraling winds to roar from out of her raunchy rear. What had started out as a silent whisper of gas creeping out of her perfect plot soon unfolded into a full blown storm of stagnantly stale and excruciatingly eye-watering effluvia, her rotten gas more than a match for even Rainbow Dash herself! That all too familiar feeling of shameful pleasure returned to Rarity as she relinquished yet another volley of vile vapors into her close-fitting jeans, this time the fabric rippling against her talkative taint as the tear-inducing toot generated a fearsomely foul funk to add to the awful aroma building inside of her boutique. Although Rarity absolutely detested the mind-melting miasma that she was steadily pumping out into her workshop, she couldn't help getting some sick sexual gratification from daring to drink in her own sour fumes. That combined with the relieving sensation of easing the painful pressure stabbing away at her stomach was like an aphrodisiac to the quirky seamstress! Alas, all good things must come to and end and that was unfortunately the case with Rarity's earlier gassiness. With her stomach somewhat soothed and her earlier urgency to break wind now subsided, the inquisitive unicorn decided to end the exploration of her newly found fetishes... for now. Drawing in a humungous breath, the beautiful mare sucked in her stomach as far as feasibly possible before uncoupling the button of those fart-laced jeans. A satisfied sigh of liberation lazily sounded out from the relieved unicorn as she wasted no time at all in peeling those imprisoning pants from her physique. With a huge amount of struggling and straining, Rarity managed to tug down the jeans from her sweat soaked rear before gently unhooking them from her voluptuous hips, kicking them off into a heap upon the floor. The exhausted mare spent the next 30 minutes lazily lounging on the carpeted floor of her boutique, not a stitch of clothing to protect her modesty as the ivory unicorn remained completely naked in the middle of her shop. The perverted pony panted profusely whilst staring at the crumpled denim a few feet away from her position, tapping her chin as she contemplated her next move. "I simply can't give these to Pinkie Pie in this state... can I?" Rarity mused before a dainty blue aura encompassed the jeans as she levitated the clothing towards her. Just as she had done previously, Rarity gave the seat of the jeans a deep and unadulterated sniff before instantly regretting her poor decision, the mare suddenly breaking into a fit of coughs and splutters as a result of bombarding said jeans with an onslaught of odorous emissions earlier. "Goodness gracious no! I simply can't give these to Pinkie in such an uncleanly condition!" Rarity sticking her tongue out in disgust to punctuate just how appalled she was with her own repugnant rectal releases. With one last daring sniff, Rarity's curiosity was fully appeased as she wasted no time at all in throwing the jeans into her laundry basket. *Ahem* "Now that nasty business has been taken care off, I do believe that a luxurious bubble bath is in order!" Rarity grinned inwardly before strutting off to freshen herself up ready for Pinkie's party later on...
