Passion Project

Sweetie Belle sat upon her flank in a unbreakable silence, soft pale green eyes watching the dance of flames before her in a indifferent manner. Flawless cream colored hooves digging deep into the moist wet mud underneath herself, the sky a pitch black hue with not a single star above.

The large orange bonfire in her backyard stealing the show with ease, Sweetie was used to being alone in her lifetime. The fact the sky refused to share her cosmic beauty didn't bother her the least, the soul becomes simply numb after so long in depravity.

Her multicolored mane of violet and pink, cascading down over the side of her face in a look of tragic pain. Her mane a complete mess at this moment, more a less a wild nest of tangles and knots.

Lifting up a elegant pink dress high in her hooves, she took in the flawless work of perfection with utmost awe. Rubies glittering in the pale moonlight dancing around the hem, gentle white frill roses blooming near the heart of the dress.

It showed off quite more than her usual dresses, but that was to be expected of course. Rarity had created her clothes all her life, clothing for a young naive child, blind to the world around her.

Lifting the silken fabric high, Sweetie took a long wanting inhale from the dress. The soft dainty scent of her loving sister still wafting from deep within, this certain piece of art shorter, a bit more revealing and of course far more mature.

A dress fit for a mare…

Sweetie tossed the dress weakly into the blaze before her, the hellfire engulfing the fabric easily absorbing all the pain she felt. Watching in silence she let her heart shatter over the open flames, crystalline tears of regret trickling down her cheeks.

Earlier.

“A dress fit for a mare, darling!” Rarity flaunted her hoof playfully towards her little sister, violet mane of silk tied into a towering high bun.

Lovely cateye rose colored glasses rested upon her muzzle neatly, her dark blue magic floating various objects across the room haphazardly. A sewing needle effortlessly tightening the fabric in chosen areas, while multiple satin roses of every color floated around the mare daintily.

“I've only been a mare for like a week, I'll always be your little sister forever!” Sweetie stood perfectly still as Rarity made adjustments, as a child she disliked modeling, though through the years she grew to love it.

Helping her older sister create such lovely outfits, even if it was in a roundabout kind of way. She cherished the time they shared with all her heart, Rarity often called Sweetie her muse, a pony she drew beauty of the world from.

“Maybe so, but this is a special occasion! Your journey to marehood, the path that will lead you down towards your destiny!” Rarity gave a beaming smile of delight, tugging the back of the dress as it snugly fit into place.

“As if, I'm just... Sweetie.” The young mare lifted a small hoof upward, hiding away a sly smile politely.

Her soft green eyes gazing ever deeper into the mirror's reflection before her, perhaps for the first time seeing a grown up instead of a child. This dress bringing forth her mature feminine light, hugging blossoming curves and developing body in a passionate embrace.

It made her feel loved.

It made her feel beautiful.

Sweetie stood blushing a bright pink across her cheeks in embarrassment, diverting her eyes away from the mirror and glancing down to her hooves in slight shame. Her thoughts had begun to drift towards her heart, tail lifting high in complete and utter delight of a drifting dream.

“Heehee, I know that look!” Rarity snapped the mare back into reality, giggling aloud as she swayed her body side to side playfully, placing sewing tools back into their rightful positions.

“Is that so Rare?” Sweetie humored her older sister, flashing a devious smirk of sarcasm.

“What, you think I can't read ponies!?” Rarity gave a soft huff, her coat fluffing out near the chest area elegantly.

“Like the time you thought Lyra and Bon, were lovers?” Sweetie lifted both hooves up over her muzzle in a childish manner, bursting into a fit of warm melodic giggles.

Rarity blushing a slight crimson hue across her cheeks, quickly recovering with a flaunt of her hoof and a flip of the mane, freeing it from it's bun prison. Long waves of violet cascading down her backside much like a waterfall, her ocean blue eyes glancing to her little sister playfully.

“I still say give it time.” Rarity gave a knowing wink.

“Then do tell, what's on my mind?” Sweetie leaned inward, her tiny muzzle inches away from her sister's mockingly.

“Nothing serious, just the look of love dear.” Rarity lifted a feminine hoof, booping her sister on the nose.

Sweetie quickly folded ears back in absolute surprise of those words, not wishing to give her sister too much credit, but she was right on the point. Cheeks flushing as the young mare took multiple steps backwards, nearly stumbling over a sewing kit on the floor clumsily.

“Ah, I see I'm right!” Rarity gave a smug look of satisfaction.

“As if, I'm not in...that.” Sweetie gently tapped her hooves together nervously, eyes falling to the floor before averting her gaze.

Rarity giggled draping slender hooves over her little sister’s shoulders playfully from behind, placing her chin upon the right side with a sophisticated bat of her long lashes. Sweetie growing ever nervous indeed, hooves quivering in place as she tried helplessly to swallow the large lump in her throat.

“Pray tell darling, who's the lucky stallion?” Rarity quipped with the utmost curiosity.

“Nopony.” Sweetie gave a deep blush, feeling the lovely caress of her sister's underbelly upon her backside.

“I thought we shared everything?” Rarity was even more curious, her thin brow raised in a quizzical manner.

“We do, just I can't share this…” Sweetie pulled away from the tender touch, the very embraces that haunted her dreams.

“Oh!” Rarity studied her sister, watching every movement with care.

The older mare letting her sister walk over to the corner of the room, Sweetie plopping her flank onto the wooden planks with a loud thud. Rarity biting her lower lip,tracing her soft untouched hooves across her wooden work desk.

Searching her mind for the right words, in hopes that she could ease her sister's troubled mind.

“Is it a unnatural love dear?” Rarity let her sweet soprano voice waft across the room.

“Yes.” Sweetie winced in shame, pinning ears back in pain.

“Hmm, I'd never judge you.” Rarity gave a polite reply, her voice calm and collected.

Sweetie held back a trail of tears from her sister, the secret she hid away for so long begging to break free into the world. The young mare feeling her heart crack along the edges, as if it were on the very path of shattering into a thousand pieces.

“I just can't say, I simply need to move on.” Sweetie turned to face her sister with tear soaked eyes, her muzzle forcing into a broken smile of hidden pain.

“Is it perhaps Bloom?” Rarity rushed over with a soft coo, embracing her sister in a tight loving hug.

“I wish.” Sweetie wrapped hooves around the waist of her delicate sister, leaning inward to inhale the sweet scent of her sister's mane.

“You can tell me.” Rarity lifted the chin of her sister sweetly, both mares locking eyes for the first time ever.

Sweetie felt utterly weakened, her knees becoming like jelly from this sight of perfection. Those ocean hues flawless in nature, her lips absolutely soft as silk, pouting with a cute curve of the lower lip.

Sweetie felt time freeze, this beauty would forever haunt her days. She would no longer be able to run, hide away her feelings behind a faux personality. The mare knew at this moment, if she truly were to ever be happy, she'd have to take the plunge.

Leaning inward with care, their lips suddenly touched. Sweetie melted into the embrace, her full soft pink and purple tail swishing around in ecstasy. The fluff upon their chests intertwining with care, Sweetie deepening the kiss slowly, nibbling the upper lip before tracing the lower, giving it a tender suckle.

“Pop!” The echo of a hoof upon cheek filled the claustrophobic room loudly, Sweetie yelping in pain as she fell onto her flank stunned.

“The audacity, the nerve!” Rarity shuffled backwards in horror, her eyes darting around the room in panicked confusion.

“I'm ever so sorry, it was a mistake!” Sweetie held a tiny hoof outward in total shame of her behavior, her heart racing as if ready to explode out of her chest.

“You, I?” Rarity mumbled with burning red cheeks, turning her back towards her little sister.

“Rarity, please I need you!” The mere thought of losing her beloved sister, caused her heart to shatter in place somberly.

The older mare dashed out of the room in terrified anxiety, her hoofsteps fading down the stairway as the loud slam of the front door echoed through the air. Sweetie curling into a small ball on the floor, sobbing loudly in devastation, her body growing numb as her heart turned to cold stone.

Her nightmare had come true, she lost everything.

Present.

The dress soon turned to ash before her very eyes, the blaze claiming it's due with no sense of empathy at all. Sweetie could feel her cheeks sting from the shed tears of this horrid night, sniffling softly as she hunched over beside the flames, a look of loss in her large colorful eyes.

The sound of delicate hoofsteps lost on her weary soul, the young mare never shifting from her broken position, even as a tall shadow of a pony towered behind her intimidatingly.

“I'm sick, aren't I?” Sweetie pouted in a voice of defeat, her eyes watching the flames dance in the dead of the night.

Rarity silently taking her place at her sister's side, the cool night sky caressing over both their coats as if to try and calm them. Rarity softly intertwining her tail with Sweetie's, locking them in a swirl of pink and violet firmly.

Sweetie whimpering as she felt the embrace of tails, ears perking up high as the spark of hope had ignited deep within once more. The young mare turning her head to the right, meeting a familiar muzzle with a helpless moan.

Both mares locking lips once more, this time feeling the passion of a renewed love between them both. Rarity easily tugging on her sister's lower lip tenderly, warm tongue sliding in her mouth lovingly, dancing with her own in a silent embrace.

Sweetie had so many questions, though this moment called for no words at all. Feeling the knowing hoof of her sister raise, running a expert touch through the pink strands of her mane. Sweetie sobbing softly in silence, her heart exploding forth in a warm wave of pure ecstasy.

Rarity placed her passion into a series of slow deep kisses, rolling her little sister onto the moist cool ground. The towering blaze of the bonfire casting it's orange glow upon the equines elegantly, Rarity being taken back to that night.

The night she knew.

Months Earlier.

Rarity sat up late in her room with a numb mind of blank satire, anytime she tried to drift to a original idea, she'd be knocked down into a reality of monotone apathy. Her drive to create things of beauty fleeting by the minute, thoughts drifting to a certain young mare in her life.

The way she moved, the way she laughed.

Any small motion she completed was enough to bring vast light into the world, her slightest flash of a innocent smile, bringing forth untold beauty. Though those days were far and between, once Sweetie grew into a enchanting mature mare, everything changed.

Gone were the lovely afternoons of helping her model, or the late nights of creating the perfect dress. Sweetie had her own life now, one that didn't quite involve her stuffy older sister.

Her muse fading into the pages of history, memories she'd treasure forever.

Rarity could feel her ears perking upward suddenly, the unicorn tilting each slowly around the room. She could've sworn that a familiar noise made itself known, standing to her hooves Rarity walked to her open door.

The delicate voice of sobbing was clear as ever now, Sweetie's room full of the melancholy song of sorrow. The mare biting her lower lip in curiosity, usually she was fast asleep by now, Sweetie must've thought the same.

It wouldn't be right to pry.

Yet the sobbing caused the older unicorn to whimper, the mere sound of her little sister crying, enough to shatter her heart into pieces. Rarity had to simply peek in to make sure all was fine, taking each step carefully down the dark hallway.

Sweetie had the saddest eyes, Rarity had ever seen.

Lime colored hues full of a sense of vast distance, as if she were lost in a dream. The young mare looking tired and worn, she had grown far too weary of playing pretend.

Of lying to herself and those around her.

Sweetie curled up on her bed, wrapped in rusted chains of depression, eyes wincing shut with pain of a long day. Praying that slumber would find her soon, held tightly in her hooves a certain object of familiarity.

Rarity knew it well as she slid her head into the room, under the cloak of darkness. Clutched by her sister was the very first dress she had ever created, it was nothing to be proud of at all, the color was drab, the hem a mess and the frill non-existent.

Yet Sweetie must've dug it out of the waste bin, all those long years ago. Cherishing it as a personal memento, Rarity watching her sister caress it with tender care of a loving hoof.

The young mare inhaling the scent of her sister lost upon the fabric, a gentle calming smile forming over her lips, drifting off into dreams that might never be.

Rarity knew her muse found affection towards the private times they shared, deep within her own soul she felt the same. The shortness of breath, the fluttering of her heart and the warmth of love building within.

She loved her sister more than the world, though it was just that.

The world might not see it the same.

Present.

“If in the morning, the world left us behind?” Rarity slid up atop her little sister in growing silence, Sweetie gazing into her eyes, slender hooves cupping her cheeks with care.

“I wouldn't care, as long as you stood at my side.” Sweetie leaned inward kissing Rarity's lips deeply, both mares moaning in delight from the warmth of the fire.

Rarity breaking the embrace as her tongue lapped the soft flesh of Sweetie's neck, playfully caressing the collarbone with a dainty dance of her mouth, suckling deep on the rim of the bone, roughly biting down as the filly yelped.

Rarity knew what she desired to create, the perfect passion project for her muse to be apart of. The older mare kissing down over the belly of her sister, smothering the pelvic bone in a flurry of embraces.

“Ohhh, my muse! Such beauty and innocence!” Rarity growled as Sweetie gave a loud moan in delight, hooves swaying to the side, long slender legs spreading wider.

Rarity smirking devilishly as she used her magic to float over a few objects out of the darkness around them, a small leather cropping whip cutting through the void, smacking across Sweetie's flank with a loud pop.

“Ahhh, it stings!” Sweetie whimpered in pain, a second lashing exploding out of the night, across her round plump buttocks roughly.

The child screamed again, Rarity cooing into her ear calmly. Kissing her sister deeply as a pale blue aura began to wrap a dark leather belt around Rarity's waist, a small click echoing across the backyard wickedly.

“Pain is the sweet build up to pleasure, I want to share both with you!” Rarity giggled her magic gently fastening a large stallion strap-on across her hips, Sweetie moaning aloud in shock of this revelation, the whip lashing her ass once more.

The world spinning as Rarity plunged her large horse cock deep into her sister's waiting folds, Sweetie screaming out in pain like no other, her hooves wrapping around Rarity's waist for mercy.

The older unicorn moaning with ecstasy of the moment, pumping her faux cock deeper into the extra tight opening of her sister. Sweetie panting at a lost for words, her body shivering even as her hips grinded and pumped the cock deeper.

Rarity made sure to take each mighty thrust hard and slow, the clacking of hips echoing across all of Ponyville. Sweetie feeling herself coating the shaft in her sweet warm juices, her tail swishing as her hooves slapped Rarity across the muzzle with a loud pop.

“Harder! Ohhhh!” Sweetie felt her body growing numb, her sister riding her faster and faster , the long hard cock smashing and grinding deep into her inner walls.

Rarity leaned toward her baby sister, locking lips in a passionate kiss of forbidden love. Her hips pressing upward sharply, pumping the cock deep into the velvet folds as Sweetie screamed in untold pleasure.

Her body growing limp as she exploded forward in wave after wave of sweet scented ecstasy, both mares intertwining in a embrace of true passion.

Creator and muse, one in the same.

Creating a true project of love, one cemented in a act of honesty.

Both ponies tired of running, each willing to face the consequences together.

The Morning.

The bonfire dwindled ever smaller in front of the ponies cuddling closely, after a long dreamed of night of passion, Rarity watching in glee as her little sister slept calmly in her hooves, the sun slowly peeking out from the horizon above.

The light of the new day bringing forth the challenge of sharing a forbidden love with the world, what exactly the future held the unicorn did not know. Yet a smile formed across her muzzle, because no matter what, she had everything she needed right here.

Rarity giggled sliding upward to her hooves gently unclicking her toy, silently walking over towards the house to make them both a few cups of coffee. Humming sweetly she trotted in through the backdoor, her coat shimmering vibrantly with a sense of happiness.

“Well somepony is happy!” The melodic tone of her mother spoke up from the kitchen table, both of Rarity's parents enjoying a makeshift breakfast to her right.

“Uhh, I met a special somepony?” Rarity sheepishly spoke with a crimson blush, pinning her ears back with uncertainty.

“Ohhhh, do we know him!?” Her mother gave a squee in excitement.

“I think you might, she's my muse.”
