The Power of Music

"Ms. Octavia! Curtains will go up in five minutes!"

"...Right. Thank you. I'm just about prepared to go on," Octavia said with a confident smile on her face.

The world-famous cellist rose to her feet. She was dressed in an elegant,white tuxedo shirt, a pink bowtie, and sleek black dress pants with matching black dress shoes. She strode to her prized cello, which was shining ever so softly in the backstage light.

Her softball-sized breasts jiggled with each step she took. Her ears flickered at the sound of whispers—excited, by the sound of them—coming from the staff backstage. A soft smile drifted onto her face. She placed one hand on her hip, standing tall with her solid five foot, seven inch frame. She grasped her beloved cello in one hand and looked towards the nearby dressing room table where her brand-new bow was laying in wait.

She giggled. "At last, I finally get to use this elegant piece of craftsmanship." A couple of steps later, and she found herself near the table. She then took the bow out of its case and examined it carefully.

The bow was well-coated in black lacquer which absorbed all light that struck it, making its color stick out in most environments. It felt smooth and sturdy in her hand while it also gave her a warm feeling against her palm upon holding it. The bowstring didn’t have a single loose hair or lint on it, a sure reflection of its high quality! Seeing the sheer beauty of her new bow filled her with newfound confidence.

Her eyes narrowed. There was a gold inscription on the interior wall of the bow. Right as she was about to read it, though, the stage coordinator interrupted her.

"Showtime, Ms. Octavia! Have a splendid concert," he said.

"Thank you. I shall do my best,” Octavia replied. She then made her way to the stage with her chin held up high, eager to show the world the fruits of her strenuous practicing. She strutted forward, each step bouncing her perky bosom, her firm hips swaying from side to side. However, her heart was pounding within her chest, causing her to take shallow breaths.

She lowered her head and took a deep breath.

“Okay Tavi...relax. This is just another concert. You can do this,” she muttered. She stepped onto stage and faced the tall curtains, waiting for the show to finally begin.

The red curtains rose high into the air. A wave of energetic applause shook her body from head to toe, yet her eyes remained open and focused. The once-spacious concert hall was filled to the brim with ponies of all ages. The audience even filled up the balcony level, which rarely sold out. She could feel the stare of thousands of eyes on her body, her heart rate speeding up the more she wondered about that fact.

She soon made her way to the music stand and chair, all with a calm look on her face. She took a standard, quick bow before taking her seat. Her left leg made its way around the base of the cello for support and sat up straight. Her left hand grasped the long neck of the cello and her right hand held the bow toward the ground.

In front of her large, purple eyes was a famous, three movement piece composed by the great Beethoofen titled "Symphony No. 34". The crowd then grew silent as she closed her eyes and lifted her brand new bow for all to see. As soon as the bow contacted the strings of the cello, a sharp jolt of magical energy shocked her hand!

She grunted in pain. A nervous grin formed as she felt that strange, sudden sensation. She clenched her right hand, gritting her teeth as she tried to shake off the pain. She took a deep breath. Her fingers moved back into position, her grip tightening around the bow. Now composed, she begun the first movement of her piece.

Resonant, low notes filled the spacious concert hall. The pitch, the melody, the tone, it was all perfection. She felt it, and so did the audience as they were entranced by her playing. Every note, every measure, flowed from one to another, creating a musical experience no other pony in Equestria could hope to recreate.

However, unknowingly to her mind, her own music was starting to cause some unnatural change in her body. Each note she played sent a familiar tingle down her spine. She closed her eyes to relish in these small sensations. Thoughts of her body pulsating with the music came to her mind.

Her beating heart slowed down to match the tempo of the music. She felt those beats through her breasts, which caused a small blush to appear on her face as she felt more in tune with her performance. Thoughts of freedom also filled her mind, drawing unwanted attention to her clothes. Her smile faded away thinking about those constricting clothes of hers, yet her desire grew to be one with her music.

As the performance went on, the bow glowed softly and her bust started to expand. Bigger did it get, with each measure adding a couple of inches to her bust size. The firm flesh pressed against her white concert shirt and started to stretch it, sending slight ripples of pleasure to her mind. Soothing, cool breaths left her body with each ripple she felt.
Her hips begun to swell too. They strained against the fabric of her sleek-black pants. Luckily, the dull sounds from the stretching fabric was covered up by the sounds of the cello.

Her flank filled up with layers of fat and muscle, pushing her off her seat and filling her entire lower body with a warm, inviting feelings. The chair creaked beneath her growing flank, but she simply shifted her weight and continued her performance. She couldn’t help but smile and move her upper body, emphasizing each smooth stroke of her bow. She was playing Beethoven’s work after all, one of her favorite classical composers of all time.

The bow continued to dance across the cello, with her growing a few more inches with each pull. Her entire body expanded in time with her soft, controlled breathing, pushing against all of the remaining wrinkles in her clothing. The tiny pulses of pleasure were now tickling her at nearly every point of her body. Her body seemed to sing with the music—her legs twitched, vibrating with a high C, and she felt a surge of warmth in her chest as her next G sang out across the stage.

Toward the end of the first movement, she had grown a couple of bust sizes and was now carrying melon-sized breasts. They bulged through her shirt and moved up and down with her breathing. She felt a heavier, downward pull on her chest that made her groan in approval.

Her hips and thighs expanded until her pants look almost painted on. She was now around six feet, seven inches tall, a full foot taller than normal. her ears wiggled a bit at the whispers from the crowd, but once again, she continued to ignore such rude distractions and focused on her performance.

She then finished the first movement and the audience gave her a resounding applause. She took a deep breath to psych herself up for the next movement. However, since her clothes now felt so tight on her, she opened her eyes to examine herself. Whereas before she could see the entire sheet of music in front of her, her enlarged chest managed to cover up half of the sheet. The outline of her straining bra also left a very deep impression on her shirt.

She then tried to shift her weight to compose herself, but she felt both of her legs and flank struggling to move. The tightness from her pants made her rather uncomfortable, and any sudden movements caused some the pants’ fabric to tear.
Her eyes widened. She took a quick glance at her black bow, which was glowing softly with magical energy. She giggled. She rubbed the bow in her hands for a bit, feeling the small sparks tickle her fingers. She moaned at the energy she felt, but then set her gaze back to the music.

She lifted her bow up once more and she begun the second movement. The music was lot more soothing and enchanting than before, as expected from a standard three movement classical piece of music. Still, the changes continued to intensify all around her body.

Her bust was now expanding at a faster rate. Her large, purple nipples were getting harder as they erected and formed a noticeable outline on the edge of her shirt. The increased pressure from both the force of the restraining shirt and the increasing volume of milk and fat within her breasts sent greater waves of pleasure through her body. She could not help but moan quietly to herself as a faint blush appeared on her face.

Her pants started to tear apart as her hips and thighs continued to expand. Although those sounds continued to be covered up by the music, the rips got to a point where her smooth, gray flesh was exposed. She heard some more gasps from the audience, but that didn't faze her performance at all.

She grew again, panting with each shock of magic she felt against her skin. Her eyelids pressed more tightly together, moaning as she felt her legs swell against her pants. Ears twitching with each new measure, she tightened her grip on the bow. Each note came easier than the last, her right foot tapping—and growing—alongside the tempo.

Halfway through the movement, she passed seven feet in height, at which point one of her shirt buttons popped off her shirt. As she hit eight feet -- another button popped off --flying further than before. And this continued for every half foot she grew, until all of her buttons came off and her own shirt started to tear down the center.

Throughout her entire growth spurt, she started to let loose louder moans. She felt her marehood feel damper by the second. She could not help but squeeze her thick legs together to embrace the wetness, which caused a couple more rips in her pants.

The sweet smell of her love juices reached her nostrils, which just made her blush even harder and breathe more rapidly as she get more turned on. The chair she sat on started to creak and bend under the increasing, now plump rump of hers. Both the cushion and metal supports dug into her flank. She bit her lip as that pressure felt so invigorating for her.

The glow around the bow grew brighter as she continued to slide her rump further into the chair. She pressed the bow tighter against the strings, ignoring dynamics as the notes got louder. Her controlled breathing became short, desperate gasps as her face flushed three shades of red deeper. Even sweat drops formed on her forehead and rolled down her cheeks. Still, she showed no signs of slowing down.

Instead, she gasped and twitched she hit the climax of the second movement! A sharp rip could be heard as both her shirt, pants, and dress shoes fell off her amazonian-like body to the stage floor. She heard the loudest gasp and whispers yet from the audience.

There, in the bright lights of the stage, stood a 12 foot, hyper-curvaceous pony. She was sporting beach ball-sized tits that nearly reached the bottom of her stomach. Her eyes were closed. Her cheeks blushed a shade deeper of red from the growing sensations she just felt.

Now in only her pink underwear, with both her bra and panties struggling to hold in the growing body they contained, she sighed in relief. With her pulsating, erect nipples and her exposed cameltoe, no longer did her concert clothes restrict her pleasure.

She opened her eyes and looked towards the crowd, whispering and giggling to themselves. Obnoxious wolf whistles rang through the air before security escorted them out for disruption of the concert. She widened her eyes, covering her mouth to hide some of her beet-red face.

Her mountainous chest had by now completely obscured her view of the music stand. Though she knew it was futile, she used her free arm to cover her cleavage, pushing down against the two mounds of flesh hanging from her body. She held her thick legs against one another, struggling to contain her arousal as beads of sweat poured down her face.

She turned her head over to her manager, who was covering his eyes with his clipboard and made a "continue" gesture with his hand. Octavia then looked at her magical bow, which had grown with her and the cello.

She turned her head back to face the audience. She sighed and lowered her head. The frantic whispers continued to annoy her ears, yet her raging blush soon began to fade. Her sweaty hands gripped tighter on the neck of the cello and the bow. Soft, peaceful breaths returned as she lifted her bow in the air, silencing the crowd.

She closed her eyes once more and begun the final movement. Suddenly, a flurry of pitch perfect cello notes silenced the crowd and entranced them. Crazy arpeggios and complex rhythms soon filled the concert hall. She closed her eyes as she played, biting her lip as the pleasures of growth continued to consume her mind.

The growth effects were near instantaneous this time around. First, her already curvy lower body swelled larger. Her thick thighs became perfectly toned with layers of strong, lean muscle while her foal-bearing hips were getting wider than her shoulders, and her round flank was filling up with more and more of her soft, gray flesh.

Each square inch of extra mass felt like a finger stroke to her marehood, her moans steadily increasing in intensity. The wetness returned to her loins, soaking them quicker than before. Her massive thighs twitched from her femcum. She couldn’t help but start panting with these stronger sensations.

Her twelve foot frame shuddered and grew to newfound heights. With a resounding crack, the chair finally gave way to the weight and buckled, sending it flying to the backstage wall behind her. The staff were likely in a panic, she thought with a chuckle.. Yet, that mattered little to her as she was fully immersed in her own performance.

Her rump hit the wood floor, shaking the whole stage and knocking her music stand over. Notes continued to fill the air as the bow continued to dance around the strings. The stage continued to shake under her growing weight in her attempts to stand up. Once on her two feet, she gripped the bow even harder, driving each set of notes louder with each broad stroke.
The bow glew its brightest yet. She held her eyelids shut tight, smiling as the orgasmic feelings of growth entered her mind. Upwards she grew, gaining inches at a rate of ten inches per thirty seconds. The underwear stretched thinner and thinner as it fought against the growth, squeaking out more deep moans from her.

Around the fifteen foot mark, her underwear tore apart and launched far into the audience.

"YES! I got it,” said a lucky stallion. He sniffed his prize, erecting his wings and blushing from his sudden arousal.

He was then escorted out by security with a pair of moist, flimsy panties in his hands. Meanwhile, Octavia’s bra landed in the possession of a security guard, who quickly stuffed it inside his pants with a gleeful expression on his face. Octavia giggled and smirked.

Now free from their clothing confines, her massive breasts sagged a bit and swung along to the music for all to see. Concert etiquette was being thrown out the window as some more horny audience members cheered at the sight of the growing cellist. Even the security guards decided that enough was enough and joined in the cheering.

She soon reached a towering height of twenty five feet towards the middle of this movement. Squeals of joy left her lips, her sensitive, purple nipples becoming even harder as she grew. She decided to place on of her huge teats behind the body of the cello,letting the low, vibrant sound waves it produced rumbled her exposed tit. Her head reeled back quickly, embracing the intoxicating pulses of pleasure.

Her sex was super-soaked at this point, femcum dripping on the stage. Members of the audience didn't dare move an inch as they were frozen in place by the hypnotizing music and her sexy, naked body.

Love juices flowed down the sides of her massive legs, her entire body twitching in pleasure. Thoughts of the current performance faded into the kinkiest things that she wanted to have happen to her. She chuckled as her female instincts kicked, lightly humping the air.

She could not hold in her pleasure any longer as she just moaned louder and louder with each foot she grew. Her breasts continued to swell with creamy milk and fat. A familiar pressure began to build up in her teats, causing her nipples to fully erect and throb with desire. She yelped with each pulse of her nipples and arched back, squeezing her tits together.

The pressure finally was released as her nipples splurged out delicious, warm milk. The milk fell on the front rows of the audience. Her ears twitched as she heard the crescendoing cheers from her horny fans.

Her hips have gotten to the size where they knocked over unused stage props and lights. She continued to imagine the backstage crew’s frenzy, bringing a smile to her face. Each little thing she touched with her growing body amplified her feelings of pleasure, fueling her desire to grow larger!

The music then reached its climax, cuing her most intense growth spurt yet! She instantly grew to thirty eight feet while her bust continue to expand and lactate. Her breasts weren't just splurging out blobs of milk anymore. The milk was now shooting out in streams through the gigantic-purple nipples, getting the audience members soaked with it. Her eyes shut tighter than ever and she could not close her mouth to suppress the moans of lust. “Yes! More… more!"

She continued to surge in height as her pony ears grazed the ceiling of the concert hall. She was overwhelmed with pleasure, wanting to relieve her built up sensations by doing the unthinkable during a concert. She temporarily stopped playing to lift one of her massive tits to her mouth and started to suck it.

She felt the warm streams of milk enter her mouth, tasting even better than she thought it would. Her eyes were half open as she found herself lost in her bliss, sucking like a satisfied foal with a bottle in her mouth. Every couple of seconds, she would shove a bit more of her breast in her mouth, letting her tongue worship the gushing nipple.

The milk was coming out so fast that some dripped out the sides of her mouth, running down her face and continuing to excite her titanic body. The breasts continue to increase in size despite the large amount of milk leaving them.
Still, she continued to play her music as she grew. Meanwhile, the stage itself continued to stretch and crack under the growing mare. When her head started to push against the ceiling, the stage finally broke underneath the immense weight.

"Ah! Everypony for themselves!" Both the audience and security staff started to frantically escape the concert hall. In her mind though, she didn't care. All she wanted right now was to get bigger.

So she just continued to grow and grow and grow! Her mane now brushed against the ceiling. Her head soon followed and started to push against the ceiling once more. She held her cello closer to her body, grinning as her nipples rubbed once more against the cello. She grunted and moved around, trying to maintain her playing position. But everything she did sent shockwaves of pleasure down her spine.

“Almost... there! Bigger. I… must be bigger!” Octavia yelled at the top of her lungs, lost in her lust. The entire concert hall started to crumble and break apart, trying it's best to contain the newly grown giantess it held. With one, deep grunt from her mouth, the concert hall gave way as she yelled in ecstasy!

Boom! Up soared her body, growing for everyone in Canterlot to see. Her back arched backwards as waves upon waves of magical energy pulsed through her entire body. She was almost hyperventilating at this point trying to ride out her orgasm! She humped away at her giant cello in a desperate attempt to feel some resistance against her gushing marehood.

"Y-yes! Oh Celestia... p-please don't let this stooooop!!!"

It was truly the best sensation she felt in the world. She continued to squeal and grope herself as she continued to ride out her latest growth spurt. Her femcum ran like a small river towards the floor while her humongous breasts gushed milk like a small waterfall.

Eventually, she reached a final height of fifty five feet tall as she played the final note of the movement. The crowd was cheering just a loud as one would at a rock concert. She couldn’t help but smile at the roaring crowd in the streets and took a final bow.

Her eyes then drifted down to see her new changes. Since her breasts were so large, she could not see her feet anymore. She felt the milk drip onto her legs, tickling them. She realized that she could barely get her giant arms around the back of her swelled up flank. She blushed and giggled, realizing she truly was literally the embodiment of a music goddess in Equestria.

“Thank you everypony. This has truly been the best concert of my life.”

She heard her hoard of fans chant her name for what seemed like minutes. She waved to the crowd, soaking in all of the love and smiling for all to see as the full moon illuminated her body.

Author's Note

Enjoy, everyone! :)

Encore for the Ages

"Tavi! Tavi! Tavi!"

The crowds on the streets chanted and praised Octavia after her amazing performance of "Symphony No. 34". The gargantuan, busty cellist towered over her adoring fans, smiling and waving to them, savoring the moment.

Meanwhile, her purple eyes scanned the street in front of her for signs of damage. Other than the rubble of the concert hall and some crumpled chariots underneath her, no pony had been hurt or killed by her growth spurt. She placed her left hand on her hips and sighed.

From the corner of her eye, she saw more ponies rushing towards the concert hall and joining in the already raucous cheering. Every possible space on the streets closest to her soon became filled with ponies. Soon enough, she heard a new cheer come from the crowd.

"Encore! Encore! Encore!"

Her eyes widened, and she took a step back in shock. The ground rumbled, knocking over some trash cans and small ponies over. Every soft, large asset of her giantess body jiggled for all to see. The crowd continued to grow louder, now completely hypnotized with everything Octavia did.

Her grip on her equally huge cello tightened and she closed her eyes. She knew that another performance with her magic bow would send her career to new heights, both figuratively and physically. As much as she didn't want to put ponies in danger by growing, she hated the possibility of disappointing her loyal and devoted fans more.

She raised her right hand up, silencing the crowd at last. Opening her eyes, she took a deep breath and proclaimed to the crowd.

"Everyone... I cannot express how happy you all have made me tonight. This has truly been the most successfully concert in my career, and it would not have been possible with the presence of each and every one of you here!"

Once more, the crowd's cheering entered her flickering ears. A light blush appeared on her face, but she didn't let such a sensation faze her as she lifted her hand once more.

"And so, I shall treat everyone to another performance at Celestial Park. The performance will begin in precisely 30 minutes. I hope to see you all there!"

Lowering her hand, the crowd screamed in elation, their loudest yet. Familiar chants begun to tickle Octavia's ears again. The blush on her face grew deeper as she turned her massive body towards the park, located roughly a quarter mile northeast from the ruins of the concert hall.

With her focused eyes fixated on the park, she lifted her cello up from the ground and took her first step. A boom echoed across the city streets, waking up ponies and startling others on the ground. She felt the massive weight of her breasts pull her forward, disrupting the balance she was used to while walking.

Quick reflexes kicked in as she pressed the metal stand of her cello into the pavement. She groaned and leaned back, using the great girth of her plump, round flank to restore balance. Upon returning to her original posture, she sighed and thought about how to proceed.

"Okay Tavi... baby steps. You can do it. I need to shift my weight while maintaining a good posture,” she mumbled to herself.
She took her second step, noting how much easier it was than the previous attempt. A couple of steps later, she found her natural rhythm. Her huge, gray body glided across the streets. Each step turned over small newsstands and parked bicycles, but such minor destruction didn't cross her mind.

Her breasts swayed in perfect harmony from side to side. The feeble ground beneath her feet cracked, shaking her curvaceous plot. Familiar, pleasing sensations crept into her mind, but she knew such things did not warrant her attention. She had a performance to get to and nothing was going to stop her plans.

Ponies on the sides the street came into her vision, filling up both the rooftops and the sidewalks below. She waved to them, pleased to see more ponies taking notice of her presence and, more importantly, out of potential harm's way. Around the halfway mark of her journey to the park, she spotted a large crowd growing by the minute there.

Instead of smiling at the continued support, she found herself moaning under her breath. The vibrations she felt pricked at every point in her body, sending a constant, pleasuring sensation for her to enjoy. She felt her marehood getting moist again and licked her lips as more dirty thoughts filled her mind.

Her hands and forehead grew moist from sweat, getting wetter the closer she got to the park. She bit her lip in a desperate attempt to calm herself down. It was no use. A curious hand ended up reaching down towards her marehood.

It stopped before its destination as soon as the roar of the approaching crowd reached an appropriate level. She shot her eyes open and found herself at the center of the park with every square inch of available space filled with her fans. Realizing where her hand was, she shot it back behind her back as her face grew ten shades of red deeper.

"U-um... my apologies for that," she squeaked out. But, her presence alone and the sweet, intoxicating smell coming from her marehood brought the crowd to new levels of frenzy. Their voices alone shook her soft body, letting out more gasps and moans from her mouth.

As tempting as the idea was to masturbate in front of her fans, she mustered enough willpower to raise her hand and silence them.

She giggled at first before putting on a calmer expression. "Everyone! I thank you for following me here for this sudden, second performance. As different a venue this is from the concert hall, I still ask that you practice proper concert etiquette during the performance. Now, I present to you an original work of mine entitled Canterlot Tales.

The prized, sleek black bow came out hiding behind her back. She raised it above her head to stretch out her arm before playing another long piece of music. Her eyes drifted toward it and she gasped. Right there in plain sight, was the gold inscription she had forgotten about.

Hey Tavi! Enjoy your HUGE rise to becoming the biggest music icon in all of Equestria! YEAAAAH!
<3 DJ-PON3 <3

Tears formed in her eyes upon reading the inscription. She closed her eyes and kissed the bow on its head. The bow zapped Octavia's lips upon kissing it, sending a quick shockwave of pleasure through her body. More moans escaped her mouth, but the gasps and whispers of the impatient crowd brought her focus back down to the present situation.

Blushing, she resumed her playing position. She wrapped her left leg around the cello and brought the bow to above the cello's sound hole. Her left hand gripped the neck of the cello, arranging themselves into the first chord positions of the piece. Silence found its way into her ears, signaling her to start playing.

Deep, pitch-perfect notes danced their way through the cool air. They grazed and tickled the ears of everyone in attendance. Everything sounded so flawless for Octavia, although she could hear some soft groans from the crowd below. She wasn’t surprised, considering the equally huge cello she was playing.

Still, she treated her performance as any other. The dynamics ebbed and flowed from loud sections to soft sections. Emotional inducing tremolos filled the majority of longer notes in the piece. Every note was given the proper length and matched the rhythms she’d memorized in her head. She couldn’t help but smile at how she was able to play so well despite her vastly enlarged, drop-dead sexy body.

Right as she found her playing groove in the piece, her right hand clenched and she let out a quick grunt. The magic bow glew with newfound intensity, nearly blinding her eyes when it activated. For a moment, she felt nothing happen to her body. She frowned, and proceed to continue playing for a couple of more measures.

Suddenly, her entire body twitched, and she found herself unable to stop moaning. What used to be normal, pleasurable pricks on her body turned into tiny jolts of orgasmic tingling. The music and her body were becoming one being. Every note she played felt like a teasing tap on her marehood.

Despite drowning in her moaning and music playing, her sensitive ears did not pick up the slightest gasp or chatter from the crowd. She then realized that her moaning matched the chord progression patterns of the music, meaning it would not be distinguishable from her overall performance. Her grip on the neck of the cello and magic bow tightened the hotter she got, sending more pulses of magical energy through her body.

She found herself in the middle of a complex section filled with clusters of low notes. As she played them, her already riveting rump begun to swell. One flank cheek swelled faster than the other, while the other would catch up after a couple of seconds. This alternating pattern of growth continued throughout the whole section.

However, aroused moans turned into grunts of frustration. The sudden increase in weight to her flank begun to pull her whole body back and threaten to ruin her playing position. She dug her feet into the ground in a desperate attempt to maintain her balance. Her ears started to pick up worried gasps and whispers from the crowd as as she struggled. She groaned, hoping the growing would stop.

Just as she was about to fall backwards, the piece transitioned into a faster, easier section filled with high-pitched notes. She yelped and her angelic moans returned to fill the air once more. Her chest inflated with more of her creamy, delicious milk at a much faster rate than her rump. Both of her purple nipples erected at the same time, and their areolas grew in surface area.

They swelled to nearly three times the size of Octavia’s head, and their growth wasn’t slowing down anytime soon. The milk pressure in her globes of pulsing, warm breasts continued to build up, jiggling them with every pulse of growth. Her moaning escalated in intensity to where it became barely audible and different from the music in the air.

Her entire body shifted forward, once again putting her performance in jeopardy. She bit her lip to brace for the incoming impact, but instead screamed. The floodgates opened as her nipples gushed out gallons upon gallons of milk. She felt her breasts getting lighter at last, and used her legs to restore balance.

She heard the crowd scream in both fear and arousal, but continued to play her piece. However, it turned out to be more difficult than before. Her chest had grown nearly too large to wrap her arms around to play the cello. Before she could think much about that problem, the first movement of the piece ended and the crowd erupted into applause.

She took a quick bow and looked at her cello. Closing her eyes, an idea came to her mind. She giggled to herself, and grasped the cello’s neck. It was pulled closer to her bosom and was wedged firmly in her cleavage. The blush on her face grew deeper feeling the cello in her tits and from the crowd wolf whistling her actions.

“Please, everyone. Concert etiquette, remember? This is all for the sake for the performance after all,” she said, giggling towards the end.

The crowd quieted down as she lifted the bow to its new playing position. Upon playing the first note of the second movement, she squeaked in delight. The purr of the cello shook her breasts like nothing before. Her chest continued to expand and leak its milky contents toward the crowd below.

She grunted in the middle of her moaning, now using her body to move along with the mood of the music. The magic bow’s glow intensified yet again, sending stronger jolts of pleasure through her body. Her legs shook a bit before they begun to push up against the humungous frame they were holding.

“Mmm, yes… yes,” she mumbled. A new growth spurt begun at last for the eager giantess. Her once fifty-foot frame rumbled upwards, growing at a rate of about five feet per minute. She felt her marehood getting moist again, but had to leave it alone to avoid interrupting the performance.

Upwards she surged, with her feet growing into the crowd beneath her. She could hear the whispers transcend into normal conversation levels. She felt some horny ponies jump on her feet to worship her, but the power of the magic bow repelled them away, keeping them safe from harm.

The ground rumbled beneath her growing mass, knocking over park benches and children. Flurries of fast-paced notes and complex rhythms continued to fill the air, accelerating Octavia’s growth the more they filled her ears. Her moaning crescendoed to near audible levels among the loud, intense atmosphere.

Every square inch of her soft body vibrated and sung with the performance, swelling in time with the tempo and in the appropriate, tender areas with each change in pitch. Juices dripped down her leg as she approached the hundred-foot mark in height. The musty smell of her arousal reached her nose, and instincts kicked in as she begun to hump the air. But still, her performance was far from done.

Tiny screams of terror filled her ears as her body continued to expand. Closer her lower body drifted towards the cello, pushing her pulsating breasts more apart. The vibrations grew more intense, and her mouth refused to shut as endless amount of panting and moaning escaped from it. Soon enough, at about a hundred and twenty feet in height, she felt a sharp jolt of energy strike her clit.

She reared back and let out a thunderous scream of pleasure. Her legs wrapped around the cello and grinded her soaked marehood against the cello’s back. The once engaging performance turned into a cacophony of out of tune notes and squeals. Her feet pushed their way into the packed crowd.

The screams intensified, but could not outmatch the pleasing sounds she was making. Music stopped filling the air as she increased her humping speed. The cello creaked and groaned under the weight, struggling to catch up with the gray pony’s growth rate. She felt the wood bend and crack in her thighs, each second sending shivers up her spine.

Her body approached one hundred and fifty feet tall, silence entering her ears as the crowd was all but dispersed beneath her. She felt the bow get warmer and vibrating around in her right hand. The light from the bow blinded her vision as much as the sun would. Countless benches, trash bins, and parked wagons were crushed under her expanding mass.

All a sudden, she felt her entire body lurch forward. Hundreds of tiny splinters dug into her thighs, but it felt like pins pricking her skin. The cello snapped into two halves, with the lower one shooting out like a cannon into the buildings behind her, demolishing the majority of the floors on it. With an earth shaking boom, her breasts made contact with the ground. Hundreds of gallons of milk splurged out onto the city streets as she orgasmed and continued to grow larger.

Her growth rate refuse to cease as her body surged past two hundred feet tall. The once wide street that had been filled to the brim with screaming pony fans was replaced by tons of warm, expanding grey flesh. Multiple orgasms ravaged her titanic body as it swelled to sizes that would shame most movie monsters. Every orgasm stretched the entire length of her body by fifty feet until she finally calmed down at four hundred feet. Her body laid splayed on the ruins of an entire city block, with juices and milk soaking most objects nearby. She whimpered on the ground, disappointed that her growth spurt was over.

Using her strong, toned arms, she pushed her body back into a sitting position, which caused another small earthquake to rumble through the ruined street. Her lust-filled eyes scanned the rest of Canterlot, now seeing hordes of tiny, ant sized ponies fleeing for their lives away from her. Before any more naughty ideas entered her mind, a white flash emerged throughout the whole area, temporarily blinding her vision. When the view of the city returned to her large, purple eyes, she noticed that everypony that was running away suddenly was gone. In fact, a strange silence filled the air. No sirens, destruction, or pandemonium to ruin her concentration. It was if she was back at home, relaxing in the privacy of her bedroom.

Before she would have much time to think, the bow zapped her right hand again, teasing its owner to continuing using its amazing magical powers. The evening breeze blew in her direction, stroking her erect, pulsing nipples and her exposed marehood better than her own fingers. “Oooh. I know I shouldn’t, but this all seems too good to be true.” She smirked, looking at the tip of her black bow. It sparked with an alluring, dim blue light, reminding her of Vinyl’s magic.

“No. Vinyl would want me to use this to the best of my ability. I shall deliver a private performance solely for her. My best one yet,” she said. Despite not having her prized cello to play anymore, she already had the perfect instrument to make music with.

Closing her eyes, she laid flat on her back and brought the tip of the bow close to her dripping marehood. When the bow was close enough, it zapped her clit in a teasing manner, forcing a loud moan out of her mouth. “Ah! V-vinyl, you sneaky, naughty mare.” After composing herself, she slid the tip of the warm sheath into her pulsating folds. Her pussy glew a bright blue now that the bow was wedged in before firing countless sparks inside of her body, beginning the most intense growth spurt yet.

Her body shook and expanded to newfound heights, reaching five hundred feet long on the ground in a matter of seconds. Over time, her deafening moans would turn into an actual musical melody, pleasing to the ears. She achieved perfect pitch while stuffing her now gushing pussy with the bow, ensuring the integrity of her musical craft. Had she had an audience still nearby, her erotic singing would force ponies to get on their knees in desperation and orgasm with Octavia. Tons and tons of sweating, firm, yet soft mass piled on top of her body as it grew past six hundred feet long. The bow kept its owner at bay in constant state of arousal, not allowing any orgasm until it was starting to run out of magic.

Both fat and muscle demolished more streets and buildings around the city as she swelled larger. But for all she cared, it was merely the percussion section for her masterful, original piece that she was making. Just like before, her bust expanded larger whenever Octavia moaned out higher pitched notes, while her ass and thighs exploded outwards while she was moaning in the lower range.

This continuous cycle of expansion did not interfere with her exponential growth rate, especially now that her body surpassed the eight hundred foot mark. With nothing nearby to interrupt her intense focus, she let instincts take over as she played her body to perfection. As she passed the one thousand foot mark, both of her nipples fired milk into the air, coating the majority of her upper body with her own milk.

Some droplets entered her mouth. She licked her lips together in between measures of moaning, willing her body to submit to the overwhelming magic of the bow. The surges of pleasure she felt while growing now felt almost second nature to her. Frowning, she mentally shifted her focus on making wonderful music to her mega sized body. The bow had a different agenda as it zapped her arms, forcing them to play her own body as perfectly as she was doing before.

The more she tried to alter the bow’s growth magic, the stronger the growth surges were to shut her up and enjoy her own performance. Her body grew so large that the destruction of buildings and objects felt like a soothing massage to her fur. And still, her arousal escalated to intoxicating levels. Even the most mundane tasks, such as breathing, sent numerous shockwaves of pleasure through her body.

Her growth got to the point where she was begging the bow for release. “No more… mmm, stop it,” she whimpered, still in perfect pitch, hoping that she could finally release all that built up pressure. With the tip of her two-story, building-sized toes stretching her body past the two thousand feet mark, the brightness of the bow’s magic light up the entire night sky.

Immeasurable amounts of magical energy coursed through her body, unleashing the final flurry of moans from her mouth. Cum splurged out of her marehood, drenching all nearby city blocks and skyscrapers. The milk from her already gushing tits doubled their output, now covering her entire body and flooding the streets. Thousands of tiny cracks formed in the foundation of Canterlot’s structure, threatening to rip the entire city off the mountain side to it’s doom in the valley below.

Despite the immediate threat, the musician’s monstrous body surged longer with each orgasm it experienced. “Bigger, bigger, yes, much bigger! Sweet Celestia, don’t stop!” Her limited vocabulary roared across the city and into nearby towns. And her body continued to obey the bow’s perverted wishes. Her body refused to stop expanding. How Vinyl was able to put so much energy into a tiny object was a mystery that tickled Octavia’s mind for a split second before being replaced with a ravenous desire to grow.

After reaching the mile mark, her body’s growth rate finally plateaued, but still showed no signs of stopping. Every inch of Canterlot was now flooded with cum, milk, or crushed under her body. Thoughts of enveloping the world with her breasts alone tugged at her mind, or crushing entire continents with her godlike ass. But before those wishes could become reality, the blue light from her pussy vanished, along with her conscience as exhaustion overwhelmed her body.

The now three-mile long mare laid unconscious over the ruined capital city for what seemed like hours to her.

When Octavia opened her eyes, images of clouds filled her vision. She groaned, trying to crane her stiff neck to see what was going on. “Oh my… how much have I grown overnight?” She looked down and saw… a sea of bright blue that was ebbing back and forth against her legs. “So big. Oh, yes. Bigger, always need to get bigger…” In the corner of her eye, she saw a silhouette of an equally giant and strangely enough, clothed, mare standing a couple of relative feet away.

"Ms. Octavia... Ms. Octavia! A-are you awake?"

"Eh?" Her vision returned at last and she found herself in the Canterlot general hospital completely back to normal size."How did I…?”

The nurse responded. "Oh, don't you worry about a single thing. The princesses took care of your growth problem when you were fast asleep. Anyway, your concert last night was a sensational success! I wish I could have seen it with my own two eyes,” She said, sighing and looking out the window.

Octavia took the time to observe the fluffy white ceiling above her head as well as the blue bed sheets she was in. Underneath the sheets, she was wearing a typical hospital gown. Taking some time to peek under them, she noticed as her breasts and ass returned to the normal relative size.

With her mind set in reality, she giggled and responded, "Oh. I'm surprised you didn't see me considering how large I was."

"Hee hee! Yeah, but I only saw a mass of gray flesh when you grew closer to Ponyville. So um, h-how did it f-feel?” asked the nurse.
Octavia closed her eyes as she imagined the growth sensations again. "It was the best feeling in the world. Nothing will come close to matching it.”

The nurse blushed and turned around. "Y-yeah, I bet. Well, you are cleared to leave once you are ready. Oh! And I have a gift for you,” She left behind a small, wrapped package.

"Have a good day Ms. Octavia," She left the room and closed the door.

Octavia opened up the mysterious gift and gasped, letting her face grow flush. Her hands reached inside the box and brought the tip of her beloved bow to her lips, kissing it. A tiny spark tickled her lips, swelling her body up a couple of inches. She moaned and hoped more growing would come soon, but the bow did not respond.

Disappointed, she looked inside the box to find another small note. She cocked an eyebrow before reading the note.

That. Was. AWESOME! I’m so psyched that you enjoyed my special gift. So! Wanna hang at the usual hay burger joint tonight at 7? I gotta hear everything about your concert because lemme tell ya. No pony is going to forget that night!

<3 Vinyl Scratch <3

“Oh, Vinyl…” She said, clutching the note close to her chest. Tears of happiness rolled down her cheeks, knowing that a fun night of catching up awaited her.
