Rarity has been feeling a little on the short side.

2nd clop I've written, another macro/growth story

All ponies are anthro

It's a usually day for Rarity until she begins to feel ugly after seeing Bon Bon in her store. The lack of curves and height bring Rarity into a depression so great. Until the next day however, a "big" surprise passes by as Trixie promises a spell so wonderful.

Growth Busters

It was another work day for Rarity, having order after order. Some of which personally wanted to be measured by her, Bon Bon had been one of those. Sometime in the afternoon Bon Bon finally came. "Hey Rarity, is now a good time?

"Oh hello Bon Bon lets do it quick please." Rarity had said hastily trying to sort out a dress in front of her.

"Sure thing." Rarity began to measure Bon Bon and noticed how tall and "big" she was. Rarity was always on the shortside and somewhat flat, Rarity wished there was some way to match Bon Bon. "Is something wrong Rarity? You're just staring."

Rarity blushed at having Bon Bon notice. "Oh, I'm terribly sorry dear." It was true though, Rarity couldn't stop staring at times. Sure she had seen Bon Bon before but not this close, especially this close. Her friends varied and never had both, Applejack was probably the closest to being tall and busty but not like Bon Bon.

In one instance, Rarity decided to try and find a hat that might match Bon Bon’s dress, but was unable to reach her head; the highest she could reach was her chin, very discouraging. After about an hour of working with Bon Bon, she couldn't help but notice just how short she was.

At times she had to use her magic to grab various items around the Boutique to work on her orders. Sometimes she would even freak out so bad she forgot about her magic and asked her client to grab it. Finally after the long day of work, Rarity closed the shop and went to sleep.

Morning came around and she decided to stay closed for the day. She wished she could visit Twilight, but she was a princess now and no doubt on important business, luckily Twilight was able to teach her a few things about magic but that wasn't going to help anytime soon. Outside she heard two voices cheering, the sound was muffled from inside and she decided to look outside. Outside Rarity is able to spot Snips and Snails. Seems like those two are the ones cheering. But who or what were they cheering for?

That’s when she saw fireworks shoot out and a carriage opening in front of them. "Hello Anthroville, I the Great and Powerful Trixie has returned with a great new trick to teach someone." Trixie was always the showmare, as she walked up and down her stage boasting. "The spell Trixie has ready for this occasion is one of a kind, never seen before, and truly a once in a lifetime. And one lucky person will have the honor of learning the spell from Trixie." More fireworks escaped from the stage exploding in different colors.

Rarity wasn't sure what to think, but she figured she should check it out incase there was a chance someone would get hurt. She began to unlock her home and step outside. She began to move in front of the stage, and spoke out loud. “Hello Trixie dear, and what prey tell is this new spell?”

Trixie moved her index finger back and forth. “Trixie simply can not tell you the spell, you must experience it instead. That is the beauty of this spell.” Trixie than motioned for Rarity to come upstage. Rarity made her way up to the stage. “Follow Trixie.” Trixie began to move behind the stage, as Rarity followed. Trixie began to look through her shelf looking for the spell, deciding to make some small talk with her “helper” as she looked for the spell. “Rarity was it? Wasn’t the last time Trixie here, she made you look like a fool with your dresses and fashion?”

“Yes, you did dear, everybody laughed at me, due to your so called “tricks, witch.” Rarity clearly remembered the events as if they were yesterday.

Trixie remembered the events and felt bad, “The Great and Apologetic Trixie is sorry for that, she did not mean to.” Trixie was still going through her mess, until finally. “Here is the spell.” She hands the parchment over to Rarity.
“A piece of paper really? You made it seem so grand dear.” Rarity grabs the parchment and begins to look it over, and to her surprise. “A spell to increase one’s height? That’s impossible, no one will believe this.”

“Is that so? Let Trixie demonstrate the power of that spell then.” Trixie took a few steps back away from Rarity, and let her horn light up but only for a few seconds. “There, see anything?” To be honest Rarity didn’t notice anything.
“Let me get closer.” As Rarity stood next to Trixie, she couldn’t help but notice that Trixie was in fact taller, though she was already a head taller then her before, Rarity could now place her head in-between Trixie’s breasts. “It’s simply incredible; I didn’t think such a spell existed.” Rarity was truly amazed at how much the spell had done.

“Yes, Trixie is amazed by the spell as well, didn’t think one existed till I found it. So are you willing to do it now in front of the crowd?” Trixie asked with a wink.

Rarity still wasn’t sure to believe if it was real or not. “Such a spell has never been recorded in all of Equestria’s history, no unicorn has invented such a spell. Why would one be made now?”

“Trixie does not have an answer, but what matters is that we have the spell no? Imagine what could be done with it.”

Rarity couldn’t help but shake in place at having found a way to fix her small problem. “YES!” She began to move out to the front, where the crowd waited for both unicorns. Rarity was still happy, and everyone can notice.
“And now Anthroville, are you ready to see never before seen magic happen before your eyes? Prepared to be amazed as Rarity here begins to grow before your very eyes!” Trixie motioned towards Rarity and stepped back a few steps.

Now Rarity, don’t put too much effort into the spell, don’t want to go overboard with this. Rarity tried to start off slowly, only putting a little effort into the spell, her horn reflecting her effort, lightly glowing. The crowd began to show their displeasure at not seeing anything happening, Rarity felt nervous. She began to pour more power into the spell, which was a “big” mistake. Her horn flaring with energy the spell quickly took the energy and began to increase her height at an alarming rate. Within seconds her five foot five inches shot up to match Trixie’s height of six feet, and passed that soon enough. The growth spurt may have been quick and happened in seconds, but Rarity felt such pleasure coming from it.

“Trixie did not allow you to surpass her in height, what are you doing ruining Trixie’s performance?” Trixie was mad having the spotlight taken from her.

“I’m sorry Trixie I didn’t mean to do that, I put too much effort by mistake.” Rarity had calmed down. “Though it felt amazing.”

“Well of course it felt amazing. Trixie taught you the spell. Now if you excuse Trixie.” Trixie’s horn began to light up as she inched higher passing Rarity’s height. Her clothes starting to become too small for her. Her shirt was hugging her orbs, while her pants show a rip here and there. “Much better, if Trixie does say so herself.”

Rarity couldn’t help but stare at the body that was forming on Trixie, it seemed almost impossible to possess such a body, but this new spell had so much potential and all she had to do was cast it. “I won’t let you surpass me Trixie, my whole life I’ve been the smallest and now that I have this power I’m going to surpass everyone.” With that said, Rarity’s horn glowed and she began to grow. Her clothes were already tight on her due to her rapid growth spurt earlier. Now it was just getting tighter. If she had remained at her height, her shirt would be choking her, luckily though the shirt didn’t put up much of a fight as it soon ripped off and fell to the floor, waiting for the pants to join it. “Such a wonderful feeling, why hasn’t anyone ever thought of making this before.” Rarity moaned as she neared seven and a half feet.

“You bimbo, how dare you feel the need to be above Trixie, no one outdoes Trixie but Trixie herself.” Not wanting to lose to Rarity, she began to pick up her growth speed hoping to catch up. Soon her shirt and pants ripped off clean, though she wore nothing underneath.

“What’s this? No underwear Trixie? How naughty of you,” Rarity couldn’t help but smile, already hitting nine feet, her pants gone sometime back, and her bra now snapping off her.

“Trixie is an entertainer after all; one must know all kinds of entertainment.” Trixie winked, nearing eight and a half feet herself. During the growth, both unicorns failed to notice that both of them were feeling wet. Rarity quickly took note of this as she look down to Trixie’s nethers.

“Is the Great and Powerful Trixie now the Wet and Bountiful Trixie?” Rarity began to walk towards Trixie. Trixie began to feel her juice leak down her legs, not noticing that the spell gave such a sexual pleasure. “I think Rarity is going to have to care for your needs.” Rarity now inches away from Trixie as she passed eleven feet.

Trixie’s face turned red hearing this. She never noticed the smell coming from her legs, the sensation was too great to notice anything outside of it. “Trixie supposes she does need a little service to her needs.” Trixie moved off the stage and laid down on the grass spreading her legs inviting Rarity over. Rarity, of course, took the invitation and moved down lowering her head between Trixie’s legs wanting to get a taste.

“Seems like the entertainer will be receiving the entertainment instead of giving it.” Rarity said as she began to thrust her tongue into Trixie’s pink folds. Trixie moaned at having the wet tool enter her ever wetting pussy. Though something the two unicorns weren’t aware of were when the spell is channeled and they are in contact of someone that person will feel it also, since both were channeling, well the growth was well sped up.
Trixie couldn’t help but orgasm in about twenty seconds, Rarity’s dexterous tongue and the pleasure from the growth added new feeling to her. It was indescribable how she felt. Her white juice splashed everywhere on Rarity’s face, covering it.

Rarity has tasted cum before, but this however tasted better, she assumed it was from the increased heat both her and Trixie were feeling. She began to lick it up wherever she could find it, her face, Trixie’s legs, even the ground. She just couldn’t get enough of it. Though what she didn’t realize was that the cum was being fueled by the spell, speeding her growth even faster. Having already hit thirty feet by the time Trixie orgasmed, the cum had doubled her speed for a short while.

During the process of the growth, both of Rarity’s feet had crashed through two different building, creating holes in them, but it was too late to bring her feet back through as they collapsed. “Oh my, I’m sorry, I’m just a growing lady after all.” Rarity couldn’t help but giggle.

Unfortunately Trixie didn’t get to feel the experience that Rarity just did, but she did however feel her head crash through the Quills and Sofas. The building didn’t stand a chance as her giant head broke through, soon enough her body hitting forty feet. She decided to sit up, tearing down the building and ruining whatever was left inside as her head came up, with Rarity sitting up, though Trixie had to look up to the amazing ninety foot Rarity.

“So who is the little one now Trixie?” Rarity taunted, she grabbed her massive chest, finally having a chest to be proud of, though no one was there to touch them, well except for one person. “Oh Tiny and Flat Trixie, your superior needs some attention.” Rarity shook her chest.

“Trixie will show you tiny and flat once she is down with you. Trixie is an entertainer of many levels.” Being half of Rarity’s height made it hard for Trixie to be able to please this behemoth of a woman. Her tit flesh could almost match the size of a normal Anthroville house. Trixie began to work both hands, one of each breast, hoping to maximize the pleasure Rarity would feel, it seemed to have worked.

“Oh yes, that’s it Trixie, keep going.” Rarity loved the way her breasts felt. It was a new sensation for her, she never had any boobs to begin with, and now to actually have boobs the size of her head, made her feel so much more. Nearly reaching one hundred and twenty feet, Trixie was a little more than half that, trying her best to keep up. “I feel it coming Trixie, its building up to fast.” And just like that her bottom juices exploded covering Trixie from the stomach down.
Trixie took this time to grab what she could and lick it up. She believed this is what gave Rarity the upper hand in their little game, though Rarity didn’t know, such a bimbo. Finally after licking up what she could, her body rumbled and shook as she grew at an accelerated rate, having to move back a bit to give room, her bosom couldn’t help but smack loudly against Rarity’s own, the smack being loud to have shattered any window that was left standing.

The feeling of bosom against bosom sent a shiver between both giantess has they finally hit a hundred and sixty feet. Their bodies together now cover half of the town. “I have to admit Trixie; you are an entertainer of many levels. That was simply wonderful.” Trixie had never meant for the smack to be on purpose but took the compliment either way.
“Of course, Trixie meant to do that, I am the one with the most experience, unlike you.” Trixie waved a hand towards Rarity.

“Is that a challenge? Or are you simply mocking me?” Rarity for a fact didn’t like the way Trixie acted towards her. “If so, I’m sure I can prove that I know how to satisfy a mare such as you.” With this Rarity began to lean forward pressing her lips against Trixie, as well as moving both of her hands to each of Trixie’s gargantuan tit. Rarity was being rough with her advance, moving her tongue into Trixie’s mouth, forcing herself inside.

Trixie wasn’t going to back down so easily from this, but the groping was making her mind draw a blank, as well as the tongue play being forced onto her. She had to admit Rarity did know how to show a mare a good time. Already the two had reached two hundred feet and not bothering to slow down. They both had forgotten about the spell in their passionate love making; the spell now becoming passive to say.

Over at Canterlot.

A guard was rushing towards Celestia’s throne room, hoping to deliver important news to her. “Princess Celestia, there are reports of two giantess seeming to endlessly grow in the middle of Anthroville.”
Celestia had put on a face of annoyance. “Are you sure? It’s almost cake time, I don’t want to be interrupted.” The guard simply pointed out the window facing Anthroville. Though very small compared to where Canterlot rested, she can make out two figures groping and kissing each other from afar. “Oh no, not again.”

“Again your highness?” The guard asked confused.

“Oh, it’s nothing, do not worry, I’ll have this problem fixed, I’ll be right back.” With that Celestia began to take off to the two growing anthromorphic unicorns. After a while of flying, Celestia finally arrived, and now noticed the two had grown to three hundred feet! What disturbed her the most though, was one of them was one of the elements.

“Rarity how could you?” Celestia was forced to use the old traditional Canterlot voice in order to be heard. Even though she flew eye level with them, since was too tiny to be noticed or heard through normal means.

When the two heard the loud voice speak, they broke off to take a look. “Oh my, Celestia what are you doing here?”

“This is THE princess Celestia? She is nothing compared to the Giant and Bountiful Trixie.” Soon after, a slap went across Trixie’s face, the slap can be heard for miles.

“That is not how you treat royalty. One should know, having many chances of becoming one, and serving for them, that was very rude of you Trixie. Now apologize.” Rarity was mad at the remark Trixie had made. Rarity knew even at her height, the princess was still above her, though not literally at the moment, as their bodies continued to swell and length, passing four hundred feet.

“Trixie is far too vast to be under anyone, it is her who should be worshipping Trixie, and her goods.” Trixie lifted her bosom, they were much larger than Rarity, considering she had a bust when they started all this. “And if you wish to stop Trixie, then go ahead and try.”

Rarity had had enough and tossed herself at Trixie. Both giantesses began to fall backwards, destroying whatever was left around them underneath their bodies.

As the two began to wrestle each other, Celestia in mid-air began to wonder how she would be able to surpass their height. Until she thought of an idea, quite glad she was quite the big distance away from, they wouldn’t have to worry about being hit midflight. She began to channel the same spell that the two were using, but at a much greater volume, hoping to at least match half their height. She was glad she was an alicorn, or else this feat would have been impossible for a normal unicorn. Soon enough her already impressive seven feet, began to surge outward, quickly hitting twenty feet in ten seconds, swelling ever larger.

For some reason during the wrestle, the spell seemed to have gained some power and began to increase their size yet again and add some muscles. Giving their bodies tone and definition to them, though the muscle increase wasn’t much, it was an obvious change in the unicorns. Starting to pass six hundred, hitting six hundred fifty soon enough due to their aggressive behavior, the two rolled around back and forth each gaining the upper hand.

Celestia now noticed their increased growth rate and decided to do something else. Though she already covered a hundred feet, it wasn’t going to be fast enough. She began to fly down to where she can reach both women’s love tunnel. Celestia was glad she was long enough to reach both at once, but she needed to act fast. Putting a hand to each pink fold, she began to massage and move her hands in a circular motion.

Both Rarity and Trixie stopped their fighting as they both moaned out their pleasure. The pleasure having stopped the slight growth spurt, soon decreased to a very tiny amount of growth, already hitting eight hundred, it was nearly impossible to tell if they were growing or not. Celestia had done what she needed to do, now for them to finish their part, and it came sooner than expected.

Both titans already have had their sex swore from their orgasms earlier, soon enough felt themselves releasing a great amount of love juice. To say Celestia was covered head to toe was quite the understatement. Fortunately for Celestia, both ladies were too exhausted to do anything while she licked up all their juices for herself. She had stopped channeling the spell on herself, for the fluids should do the rest of the work for her.

Which she was quite glad she was right about, soon enough her body began to swell and lengthen in-between the two giantesses, separating their bodies from each other to make room for the soon to be gigantic Celestia. Already hitting four hundred and no signs of stopping, her bosom already dwarfed those of Rarity and Trixie’s, being a princess sometimes came with an added bonus.

Finally Celestia’s height matched that of Rarity and Trixie, but soon left them behind, Trixie seeing Celestia’s bare back, and Rarity being smothered by Celestia’s breasts. The two smaller giantesses amazed at how much Celestia is growing, they thought it to be impossible, but this reality defying goddess proved it wasn’t.

Celestia was having a hard time not to give in to her urges, for one mistake could spell the doom for Equestria. Soon enough her growth spurt stopped at a thousand and six hundred feet, truly a great size. Both Rarity and Trixie sat up to look upon their Princess, amazed at the size they had acquired.

“Now is the time to end all this, hopefully it will never happen again.” With that said, Celestia’s horn lit up as everyone’s vision was blinded.

Morning came around and she decided to stay closed for the day. Rarity had decided to stay close for the day, fearing that she be mocked for her size. Until a knock came at the door, not wanting to ignore the person, she opened it, revealing a yellow Pegasus with pink hair.

“Oh hi, Rarity, umm I saw your shop was closed, and was hoping if you like to go out with me and some people I met up with. If you aren’t busy that is.” Fluttershy blushed.

“I would love that dear, let me find a fitting dress for the occasion.” With that Rarity quickly, in her terms, found a suitable dress and set off with Fluttershy, passing Snips and Snails as they were cheering for whatever was going on. She simply ignored it, for she was going to have fun with her friend and others.

Over at Canterlot.

Princess Celestia sat at her throne comfortably. “I’m glad that’s over, and no one got injured.” No one was around to hear, but she had a feeling one person was there. “You may come out Discord.”
After a few seconds, a white flash appeared leaving Discord in its place. “Why do you always have to ruin the fun Celestia? Didn’t you enjoy the feeling, it’s been what? A thousand years since you and Luna did that?”

“Yes that is true, but that doesn’t mean you need to teach one of my subjects forbidden magic.”

“What about you? You used your own forbidden magic as well.” Discord countered.

“And it was to ensure the safety of my people Discord, but enough I have business to attend to, though I already know what will happen.” Celestia waved a hand to Discord telling him to leave.

“As you wish Celestia.” With that Discord disappeared allowing Celestisa’s day to continue.
