Trixie Lulamoon was visiting Canterlot, one day in the kingdom of Equestria. The show mare hadn't been to this city in years, since she first enrolled in Princess Celestia's school of magic for gifted unicorns. But that was another time, and rather a sensitive subject for Trixie as to why she had left.
Trixie had recently returned to Canterlot, having heard that her rival, Twilight Sparkle, was now an Alicorn Princess, with her own castle in Ponyville. Needless to say, Trixie was livid; to think that her arch rival (in her mind) had attained a position of such great importance with those friends of hers. She'd show them all, though; she would make it so that all of Equestria knew the name of Trixie Lulamoon! “Now where is that shop?” Trixie checked the small map of Canterlot she was given. “I'm right here, but all there is is this alleyway!” That's when she looked down said alleyway, and noticed something at the end. Trixie walked into the alleyway to get closer, and saw what looked to be a small shop hidden away from the rest of town. 'Now WHY would someone set up shop HERE?' Trixie said. '...well it certainly is a “secret shop.' She walked towards the shop and stepped in through the door.
The shop was dimly lit and seemed very reminiscent of the shop where Trixie had bought the “Alicorn Amulet” a year ago. The shop contained all sorts of magical artifacts and books; but would it have what Trixie was looking for? Only one way for her to find out. Trixie went to the book section, not having any interest in artifacts since the amulet incident. As she looked around, Trixie noticed a single purple book sticking out from the rest. She grabbed it and pulled it out to have a look. The cover read “Forgotten Spells.” “Forgotten Spells, hm?” Trixie raised an eyebrow. “This ought to be good. I'm going to wow Ponyville with some of these done.” She rushed to the cashier desk, noticing the cloaked pony at the desk, who seemed partially asleep. Trixie checked the price of the book on the cover...which read 3 Bits. “3 Bits? That's...very cheap for a book like this.” Trixie mused. “Oh, well.” She dropped 3 Bits onto the counter, before she walked out with the book. After exiting the shop AND the alleyway, Trixie began to make her way to her caravan (which was brand new), where she was planning her “comeback show.”
The next morning, in Ponyville, numerous ponies spot a new, yet familiar looking caravan rolling out onto the streets.
“Wait isn't that...”
Numerous townsponies didn't look too thrilled about having Trixie back. However...
The caravan suddenly opened up, turning into a bright, decorated stage.
“Fillies and Gentlecolts! After a long absence and soul searching, you will all have the pleasure, witnessing the comeback of the Grrrrrrrrreat and Powerful Trrrrrrrrrrixie!”
In a flash of blue smoke, Trixie appeared before the audience. But only 2 or 3 ponies even looked at her, much to her chagrin. However, she knew just the spell to start things off. “Not impressed? Perhaps my opening spell shall convince you! SWELL ATTENTION!” Trixie yelled out, as a magic flash erupted from her horn.
A few ponies stopped to look at Trixie, wondering what the flash was all about.
'Blast...I only have the attention a few ponies...' Trixie thought. 'Why can't this spell--' Suddenly her ears twitched as she heard a hissing sound coming from her body. When she looked down, she was shocked to see her belly, waistline, and breasts blowing up. “HUH!?” Trixie could feel her hips, butt and thighs blowing up behind her as well.
“She's blowing up!?”
“Is she turning into a balloon!?”
The exclamations from the ponies watching attracted the attention of other ponies whom all stopped and looked at Trixie.
Trixie grunted a bit as her belt tightened around her swelling body, before the buckle broke. POP! Trixie's belt bust off of her body, making her swell faster and bigger inside of her leotard, while her stockings strained against her thickening legs. “GAH!! What's going on!? This isn't what I had in mind for “swell attention!”” She cried.
The bigger Trixie inflated, the more ponies stopped in their tracks to look.
Trixie could swear that every time new ponies stopped to look at her, the bigger and faster she would swell. Rips and tears were appearing all over her leotard and stockings as both struggled to keep in Trixie's growing form.
More and more ponies were looking towards Trixie as she blew up.
Trixie squealed in horror as her leotard bust off, leaving her in black bra and panties with white polka dots.
A lot of the stallions (and even some of the mares) stared long and hard with wide eyes and bleeding noses.
“WOW! What a trick!”
“She looks amazing!”
“Hey everybody! We all get to see a beautiful mare get bigger!”
Trixie wrapped her arms around her expanding body as she outgrew her stage, her enormous panty rump overtaking it all, and crushing it as it grew and swell inside those panties. Trixie's bra stretched and creaked as it tried to contain her enormous bust and deepening cleavage.
“WOOHOO!! Cleavage diving time!” A brown pelted, blonde maned Pegasus colt whose cutie mark resembled a pony diving into a pool, shouted out. He jumped from one of the clouds above and dived RIGHT into Trixie's cleavage.
“EEK!” Trixie blushed madly as she felt the colt dive into her bust.
The ponies below all laughed at the cleavage diver, drawing more attention to Trixie.
“Ah! No! Stop!” Trixie cried as she swelled like a balloon, her breasts almost obscuring the view of her huge belly which she was holding. A creaking sound came from behind Trixie, as the clasp of her bra was about to bust. “NO! NO! NONONONONONONONO!!!!”
Trixie's bra snapped and flew off, flashing her bare boobage to the world.
“WOW!” Everypony exclaimed as more and more eyes turned to look.
“AH!” Trixie hugged her bare breasts to cover them...only for her to continue to swell bigger and bigger. Twilight Sparkle's castle was right behind her, but now was being dwarfed as it was engulfed under the shadow of Trixie. “Wh-When will this stop!?” Trixie cried as she continued to blow up. “I can't even look past my own chest!” Trixie couldn't take this anymore. This was getting far too embarrassing; and she needed to get away. Trixie began to run; the ground shook with each running step she took, shaking up Ponyville and making ponies fall over, or run as they tried to avoid getting stepped on. With so many eyes on her, Trixie could only grow bigger as she reached the clouds.
The town of Ponyville began to darken as shadows were cast over it, due to Trixie. But those shadows soon spread past Ponyville. It spread along the hills, to the Everfree forest, to Sweet Apple Acres, even to Canterlot! The sun was no match for Trixie's big blue bulk as her half naked form seem to fill the sky.
The Pegasi in Cloudsdale were doing their usual duties, making the weather and such. One can only imagine the horror and shock they felt when they saw “the Incredible Growing Trixie” stomping and swelling their way.
Trixie watched in horror as her chest bulged into Cloudsdale, before looming over it as her belly began to push into it.
Numerous Pegasus mares couldn't help but point and laugh at Trixie's ridiculous looking state. Among them, was Rainbow Dash, who couldn't help but make some jabs at Trixie's expense.
“HA! What a blimp!” Rainbow Dash giggled. “She's got a size to match her ego at least! It's the Gigantic and Fat Trixie! HAHAHAHAHAHAHAHA!”
That made Trixie REALLY upset; so upset that she prepared her spell yet again. “You're a friend of Sparkle's! Rainbow Dash, wasn't it!? I'll show you! SWELL ATTENTION!”
Rainbow Dash and three other mares (which turned out to be Fluttershy, Derpy Hooves, and Lightning Dust) were zapped by the spell and sent spinning back a bit. “OW! What the heck!?” Rainbow Dash cursed.
The other Pegasi all turned to Rainbow Dash and the girls to see if they were okay. That was more than enough for the spell to kick in.
Rainbow Dash suddenly noticed her belly and sides and breasts blowing up, giving her quite the ample bust and muffing top. “ACK! Trixie, what the heck did you do to me!?” Rainbow Dash felt a big bump behind her as her hips and butt blew up behind. “EEP!”
The other 3 Pegasus mares squeaked as they inflated as well, breasts, bellies, butts and all.
The other Pegasi all gasped in shock, eying Rainbow Dash's expansion in awe (along with the expansion of the other mares. The more they looked, the bigger and faster Rainbow Dash and the mares would grow.
Rainbow Dash was blowing up like a balloon, as her entire body puffed under her clothes. “AH!!! I'm a balloon!” One big rip sounded out as Rainbow Dash's enlarging rump burst through her shorts, exposing bright pink panties with rainbow prints. “EEK! My panties!”
“Oh wow... Such cute undies...” Fluttershy whispered...when her skirt popped off, showing HER bunny-print panties. “Oh...my...!!” She blushed deep red
“Whoa! Rainbow Dash got quite the booty!” Derpy grinned, when her bubble printed panty flank bust through her pants. “YIKES! I just don't know what went wrong!” She blushed.
“Wow...” Lightning Dust looked at everyone's inflating forms, before checking her's out as her shorts ripped away, exposing some lightning-bolt panties on her thick, juicy plot. “Meep! I'm getting a badonkadonk, here!”
“W-Wait a minute...they're LIKING this?” Rainbow Dash blushed, when her top ripped open, exposing a matching rainbow print bra on her huge chest. “WHOA! I'm sporting some blouse puppies!”
“You're not the only one, Dash!” Lightning Dust grinned as she and the others lost their shirts to their enormous chests and bras as well.
The Pegasi all whistled and cheered as they watched Rainbow Dash and her girls grow...which really fed her ego, which was now growing just like her.
“Mmmm...you all like what you see huh?” Rainbow Dash started to grin, sticking out her swelling chest and bouncing it while she slapped her growing belly, which drove the Pegasi wild. Winking at the crowd as she grew even bigger, Rainbow Dash turned around and wiggled her rump, flashing her panties at everyone as it ballooned.
The other 3 Pegasi mares started to get into it too as they flaunted their ballooning bodies before Cloudsdale, which they were outgrowing VERY quickly, much like Rainbow Dash was.
Trixie couldn't believe this; they were enjoying it!? And those in Cloudsdale were too. Of course, she was still being watched as well; still growing. But she noticed how Rainbow Dash and the other mares were fast approaching her size; although THEY were floating like parade balloons.
“Eep...so many eyes...” Fluttershy blushed nervously at everyone watching, thought she was enjoying her rapidly expanding bigness.
“Ah, just go with the flow, Fluttershy,” Rainbow Dash winked at her friend and wiggled her booty at her.
Derpy just grinned goofily as she floated on her back. “Mmmm...”
Suddenly, in one fell swoop, they felt some breezes on their chests...and saw their bras were gone. Gasping, they covered their huge chests as best they can, before looking at a smirking Lightning Dust.
“Heh heh heh...” Lightning Dust grinned wickedly as she twirled the three stolen bras on the end of her figure.
“ARGH! What else could happen!?” Trixie growled in frustration as Cloudsdale became ant-sized to her growing form. BONK! “OW!” Trixie rubbed her head and looked up. “EEK! Is that the moon!? Trixie's going to outgrow the entire planet at this rate!”
Trixie squinted as a blast of magic enveloped her...and she ceased to grow.
“Well, well...what kind of trouble have you been up to, young lady?”
Trixie turned to see a very unamused Princess Celestia looking at her from one cloud. “P-Princess Celestia!?”
Princess Celestia's magic spell had only affected Trixie however, as the Pegasi mares were still swelling.
Lightning Dust was keeping ahead of Rainbow Dash, playing keep away with the stolen bras, while admiring her own enlarged bust size, which appeared to be the biggest out of the 4 Pegasi racks.
“Get back here, you bra thief!” Rainbow Dash was drawing closer to Lightning Dust, eyes on Lightning Dust's fat panty-clad flank as it grew like crazy
“Gotta catch me first, Rainbow Blimp,” Lightning Dust stuck her tongue out playfully.
Fluttershy was busy trying to cover her exposed breasts with the clouds. “Oh..oh my..! I'm topless!” She squeaked, as she kept on growing.
“Oh!” Derpy accidentally backed up her panty plot into a few amorous colts, who all hugged it.
Trixie looked towards another cloud, and saw Twilight Sparkle, who seemed to have bed-sized breasts that she was trying HARD to hold up.
“We need to have a LONG talk...” Twilight said.
“Sparkle!?” Trixie exclaimed. “Why...”
“Why do I have enormous breasts?” Twilight asked. “Because, your inflating rampage surprised me and made me screw up a spell I was trying. HNG!” She grunted and squeezed her breasts as they grew a few more cup sizes. “And they're STILL growing!” A big rip sounded out as Twilight's shirt exploded, exposing a dark purple bra with star prints.
“Yoink!” Lighting Dust flew past and snatched off Twilight's bra.
“AH!!!” Twilight turned dark red and tried to cover her enlarging twins. “Why you!!!” Twilight suddenly turned around, swinging her gigantic chest at Lightning Dust.
“GAH!” Lightning Dust was stunned by the “breast slap.”” Dizzy she stopped flying for a moment; more than enough time to be tackled by Rainbow Dash.
“GOTCHA!” Rainbow Dash smirked.
Trixie watched as Princess Celestia rummaged through her cleavage, before pulling out the magic book that had started this all.
“Hmmm...Forbidden Spells?” Princess Celestia raised an eyebrow and had a quick read. “Wait a minute...I recognize this hand writing. There's only one person...one entity who was make spells like this.
Everyone seemed to know this too, as they all came to the same conclusion.
