“Wow… Manehatten,” Applebloom said in awe. “This place is huge! No wonder Sweetie Belle is moving here,”

“I heard Las Pegasus was bigger,” said Scootaloo, sidling up next to her as they both stepped out of the train station doorway. It was a breezy sunny day in the city and there was just enough chill in the wind that they were both wearing light jackets. Huge skyscrapers dotted the landscape and throngs of ponies were traveling the street in front of them like fish packed into a small pond. It was in stark comparison to their quiet little town. The evening sun cast warm orange reflections against the high rise glass windows of the buildings directly in front of them.

“So where is her new place anyhow?” Scootaloo asked, watching as Applebloom pulled out the letter Sweetie had written them a few days ago.

“Y’all are asking the wrong pony,” Applebloom scoured the letter. “That’s strange, ah don’t see the address on here. It just says she misses us and we’re invited to come visit with the time and date.”

Scootaloo facepalmed. “Tell me you didn’t throw out the envelope that would HAVE her address on it.”

Applebloom blinked and chuckled nervously. “Ehehe... Uhhh.”

“Seriously?!”

“Well sorry!” Applebloom shrugged. “It’s not like ah completely forgot though! She lives on Equestrian Way!”

“That totally leaves out the building and room number!” Scootaloo said, swiveling her head around to look for landmarks. “Who knows how big this street is anyway! For all we know it could bisect the whole city!”

Applebloom took a few steps forwards and sighed, looking around. She froze at the sight of a large billboard.

“Well, if Sweetie’s gotten this big already,” Applebloom motioned for Scootaloo to come over, pointing up. “I’m sure somepony is gonna know where we could find her.”

Erected proudly over a huge, flat-top building was an enormous billboard depicting Sweetie Belle laying on her side in a very seductive pose with a bouquet of red roses clenched between her teeth. She was wearing a very risque red dress and staring at the viewer with seductive bottle-green eyes. The text in the bottom left corner read ‘FIRENZIA’ with a smaller shot of pantiehose and red lingerie.

“Wow,” they gawked up at the billboard. A camera flash went off next to them capping the advertisement as well.

“Does she look like… strong to you?” Scootaloo said softly. “Like the last time I actually saw her she looked fit but like… I heard she was super buff.”

“Kinda,” Applebloom commented, noting the one arm of Sweetie’s that was visible in the ad. “Ah heard the same thing but only really saw her face in the Ponyville Press. And that wasn’t even a good photo.”

“I heard she was naked outside Canterlot Boutique,” Scootaloo said, noticing other smaller advertisements around her now.

A nearby magazine rack had a stack of new unopened fashion magazines, tightly bound with string, laying on the ground. Sweetie Belle’s face creased the cover with the tagline ‘Big and Beautiful’ across the bottom.

“She’s really hit it big that’s for sure,” commented Applebloom, looking around as she and Scootaloo walked down the street. They hadn’t noticed it at first but Sweetie was everywhere around them. On billboards in sexy poses, atop taxi carraiges with just her sultry, smiling face, in windows on posters. A radio sitting atop a milk crate enthusiastically announced an exclusive interview with Sweetie tonight at ten.

One large skyscraper on the corner had spotlights being installed at the entrance. The worn out carpeting in the front was being replaced by a different work crew and there was a small crowd of ponies milling about out front. A stallion was roping up bouquets of flowers and sticking them on a cart usually reserved for luggage. Four buff stallions stood at the entrance to the building chatting amongst themselves.

“I bet she’s up there,” Scootaloo said, craning up to look.

“What makes you think so?” asked Applebloom pensively.

“Besides all the hubbub down here and the small herd of Pegasi with cameras up there,” Scootaloo pointed into the air. There looked like a bunch of indistinct pony shapes way up there but it was too far to make out.

“Can’t see ‘em.” said Applebloom.

“I can see them,” Scootaloo said, the eagle eye Pegasus straining her eyes. “All of them with cameras. C’mon, let’s go inside.”

Not two steps into the luxurious lobby a beefy stallion in a suit had stopped them in their tracks.

“I don’t see your resident pass,” he said gruffly, eying them through dark sunglasses. “What business do you two have here?”

“We’re here to visit out friend, Sweetie Belle,” said Scootaloo. “She invited us!”

“Miss Belle is not seeing fans today,” the stallion continued tersely. “I’m going to have to ask you to leave.”

“Hold on!” A small mauve stallion waved a large piece of parchment from behind the tellers desk. “Those two can go up. Let them through, Chump Change, I have their appointment and matching descriptions here from Sweetie Belle.”

Applebloom and Scootaloo waved back and shot Chump Change a look.

“Apologies. I had instructions and those were for privacy today,” the big stallion stepped aside. Scootaloo harrumphed and strode to the elevator with Applebloom right beside her.

DING

DING

DING

The dial above the steel doors ticked off the floors one by one on its way up. It was a big, old, elevator with polished brass furnishings, red cushiony seats and dimly lit gold buttons. Everything about this place screamed money.

“Is Sweetie Belle a millionaire?” wondered Scootaloo aloud.

“If she’s got digs like this ah can only assume,” Applebloom studied her mirrored reflection in the brass elevator walls. “You saw her outside practically everywhere which means she’s famous. Getting money usually follows that.

DING

The door opened and a quartet of fancily dressed stallions chattering amongst themselves. They stopped their discussion at the sight of the two mares and quietly piled inside. Applebloom and Scootaloo sidled out of the way into the dimly lit hallway. Scootaloo noticed all the stallions were sweating heavily; one of them was desperately fanning his face with a thick magazine. As the the doors closed behind them she realized it was one with Sweetie Belle’s face on the cover.

“Is this the penthouse?” asked Applebloom, looking around in confusion.

“It has to be. This is the floor with her cutie mark next to the button,” Scootaloo said confidently, looking around. “It looks like there’s been a lot of construction and stuff done here.”

There were large slats of wood and carpet rolled off to their left in front of what looked like a freight elevator. Piles of nails, construction tools and boards littered the ground to their right. The air held a faint smell of sawdust.

It was also quite warm.

“Think ah understand why them stallions all looked so sweaty,” commented Applebloom, wiping her forehead where sweat was already starting to bead. “It’s really stuffy up here.”

“Tell me about it,” Scootaloo pulled at her collar. “I guess the windows are shut to keep out those snooping pegasi.

They walked down the hallway that was opposite the elevator. It was long and dimly lit. The temperature only increased as they ventured forth. Applebloom opened up both buttons on her collared shirt just for any room to breathe.

Finally the pair met some double doors with a large shield emblazoned on the front. A few paint buckets and brushes were off to the side on a small cart with wheels. Cautiously, the two pushed against the door and stepped inside.

“Whoa…” they gasped.

The room was huge! It looked like multiple floors were ripped out to increase the ceiling height all the way up to the penthouse. There were small frosted barely lit sconces to the left and right dotting the walls similar to a theater. Large metal fans in the corners of the room were swiveling with a dull whine and circulating the hot air. It was like stepping into a gigantic sauna.

“Ah feel like I’m outside on a hot summer day,” Applebloom balked. She could feel herself actively sweating now.

“Tell me about it,” Scootaloo said, extending her wings. “I feel like I just finished a marathon…”

“Is she here? It’s really dark,” continued Scootaloo, gazing around the dimly lit room. Aside from the rim-light from the blocked off windows the only light source was the small wall lamps. “HELLO!? SWEETIE BELLE!”

A bright green light erupted from above in the far side of the room.

“OH! Sorry girls! Didn’t hear you come in!” boomed a familiar, albeit deeper voice.

The previously poorly lit sconces flared green and then erupted with warm yellow light. In seconds the practically pitch black room was fully illuminated and the two mares winced from the change in brightness. After their eyes adjusted they got a better look at the room.

It was lightly furnished with a large, empty space in the middle. To the right of them were a couple huge wooden racks with metal hangers twisted to make giant coat hangers, each one holding a different giant sized outfit ranging from long dresses to short shirts and skirts. The large drawer next to it had a chestnut colored brassiere dangling from the knob. Next to that was what looked like a miniature water tower with a huge brushed steel bucket next to it.

The left side of the room was sparsely decorated and obviously still under construction. There were three giant silver containers with a magical cooling unit attached as well. Droplets of water condensation were dripping onto the floor right below it.

And at the far wall, reclining on a gigantic plush purple cushion was Sweetie Belle.

“I’m glad you made it! It’s so nice to see you girls again!” she said, her arm propping up her head.

The two girls just stared. Their little friend was a giantess. An enormous, breathtakingly beautiful specimen of a mare. Her body took up nearly half the length of the wall and her fluffy tail filled out the rest of the space. The outfit she had one was a flashy blue diamond that constrated with her white coat and was so revealing that every inch of her big, powerful body was on full display. Each arm looked like it was bulging with corded muscle, her legs like stone cut marble. Both breasts were akin to small hills resting atop one anotherm and were very very big in proportion to her body.

“Cat got your tongue?” Sweetie Belle said softly, swinging her pillar thick legs over and standing up from her seat. The floor shook as she walked over, and her two diminutive friends just stared up at her in sheer awe. Rooted to the spot like their hooves were in cement.

“How… Sweetie?” The titan of a mare stopped until she was right in front of them. Scootaloo gulped, still craning up at her. From this vantage point all she could see was the dark panties she had on beneath her skirt and the undersides of her massive breasts.

“How big are you?” Applebloom echoed, her jaw hanging open.

“I’m exactly thirty feet tall,” Sweetie Belle said proudly, bending over a little to look down at her friends properly. “Since everyone asks, I weigh thirteen tons and each of my breasts is about a little over half a ton each. The floor of this building has been magically reinforced to support my weight and I get in and out of here by teleporting to a spot near the entrance. Anything I missed?”

Applebloom remained speechless. Her friend was thirty feet tall. Applebloom didn’t even reach her knees. She was about eye level with her massive friends shins. If she wanted to she could take a comfortable seat on Sweetie Belle’s hoof, which was rounder than the biggest apple tree stump she ever saw.

Sweat was pouring off their bodies now. No wonder the room was so hot. Sweetie Belle’s big body was emanating an incredible amount of heat. It was almost like standing in front of an oven while it was turned on. Big droplets of water were splashing to the ground around them and they realized Sweetie was also dripping with sweat -the whole room carried her strong scent. Vaguely aromatic with a hint of perfume.

“HOW DID YOU GET SO BIG!?” Scootaloo shouted, her wings flapping to start a breeze.

“You don’t have to shout,” Sweetie Belle grinned. “I’ve got big ears, I can hear you just fine. But you have to excuse me if I’m loud. That I can’t help anymore.”

“Sorry.”

“It’s okay!” Sweetie Belle said with a smile. “I’ve got some explaining to do. But it’s got to be our secret! I haven’t told anyone else.

With the determined nod of her friends Sweetie Belle explained everything from the top. How she felt at the start. Meeting with Spike. Casting a weird spell on herself. The triggers of envy. Meeting Photo Finish. Erupting in height thanks to her sister. Modeling in Manehatten and all the contracts, advertising and deals she’s made that catapulted her to the top.

“And that’s that,” finished Sweetie Belle, her recap finished. “The spell either wore off or hit its limit because I stopped growing. I’m sorry I missed you girls for a couple weeks too. That was wrong of me. I wasn’t purposefully dodging you but I got famous so quick. Now I’m the biggest star in Manehatten. Literally. Once I do a few more gigs and start my fashion tour this fall I’ll be the biggest thing in Equestria! Also literally.”

“I thought it was a little weird that you were bigger when we were apple picking,” Scootaloo said, fanning herself with her wings.

“My neck hurts,” Applebloom replied, looking away from Sweetie Belle for a second to rub it.

Sweetie Belle laughed, her booming amplified voice like a pumped up concert speaker. Both her friends covered her ears.

“Sorry!” Sweetie Belle covered her mouth. “I hear my neck hurts a lot these days.”

“It’s alright,” Scootaloo said, still covering her ears. “So are you sure you aren’t, still growing?”

Sweetie Belle shook her head.

“Oh! I think that’s good?”

“Yeah,” Sweetie Belle flexed her massive arm, the thick bicep bulging up to meet her. “I’m huge, but any bigger than this might have been too much for Equestria to deal with. My food bills alone are insane! If I was twice my size I’d have to eat an entire orchard a day just for lunch!”

“But the spell does seems to have run its course,” Sweetie Belle sighed, her arm dropping to her side. “It did boost my own magic though! I can teleport no problem now! I even learned a spell that temporarily makes me smaller!”

Sweetie’s horn burst to life again and bright green streams of magic coiled around her body like a giant cocoon. Scootaloo and Applebloom watched in amazement as their friends form descended, shrinking smaller and smaller until it burst in a shower of sparkles.

In a few seconds their giantess friend had cut herself down to more than half her size.

It also left her totally naked.

“Oh, it uh, worked!” Scootaloo said gingerly, her eyes unable to tear themselves away at her friend.

“Hmm, I still can’t get down to below fourteen,” Sweetie Belle casually inspected her body, hands roaming down her washboard abs and across her muscular nude figure. She fondled her hefty breasts and was satisfied with her appearance. “I can usually get to just below half as big if I push myself.”

Applebloom was blushing madly, unsure of what to say or do. The giantesses oversized outfit was pooled around her hooves and while certainly smaller, Applebloom was still intimidated by her friends form. It also didn’t help that she was now eye level with her best friends' pussy.

“Do y’all have uh… normal-ish sized clothes?” asked Applebloom pensively.

“No,” Sweetie Belle said casually, planting her hands on her hips and thrusting out her chest. “My shrinking spell doesn’t put me at a consistent height every time and it doesn’t last for very long. All my ‘regular’ clothes are made of stretchy materials, currently at the laundromat. Photo Finish doesn’t make me those kinds of outfits anyway. Only my normal size ones are her designs.”

“You’re totally naked right now Sweetie Belle,” Scootaloo finally said, peering through her wing feathers.

“I know,” replied Sweetie with a shrug. “I can’t do anything about it girls. No clothes. So I’m going to be nude. Besides, until an airflow unit big enough is installed in this building my room is going to be crazy hot. It’s more comfortable to not wear clothes.”

“I think you just like being naked,” snorted Applebloom.

Sweetie Belle played with her long styled mane, making no effort to obscure herself. “What if I do? My body is so sexy. I don’t want to hide it and I’m not going to. You two have to embrace who I am now… and who I am is very big and frequently nude.”

Her friends said nothing. Sweetie Belle bit her lip after a silent seven seconds and tapped her manhole sized hoof on the carpeted floor with heavy thumps.

“Come on you too. Just... look at me. Please? There’s really not much I can do about all of me… I actually feel... weird that you aren’t dying to look at me considering everypony else outside does.”

The two small mares sighed together and looked up at the alabaster unicorn. It still felt weird to be looking at this sexy amazonian powerhouse that was their friend. But they were slowly getting over it the more they got a look at her. Every aspect of her exuded power and sexuality, both feminine and masculine, and her cute, slender face and fluffy hair helped accentuate her bulging features as well.

Scootaloo noticed something else.

“Did… are you making milk?!” Scootaloo said incredulously, pointing to her engorged breasts.

“Hm, oh yes!” Sweetie Belle gave her breasts a firm squeeze. Two strong jets of milky white spurted out and sailed above their heads. “Did you know there’s a spell to induce lactation? I cast it on myself as part of a charity donation thing for mothers in the hospital! I’ve been filling up those three tanks corner for the past couple days.”

“It’s also kind of fun,” Sweetie laughed, tugging her dark nipple and squirting more fluid onto the floor.

KNOCK KNOCK

“Come in!” Sweetie Belle said excitedly, letting go of her breasts with a heavy slap.

Three ponies walked through the door. A very short petite earth mare, Satin Sheets, a tall, athletic pegasus mare and a large muscular unicorn stallion all began to strut up to Sweetie Belle with confidence.

“I’m sorry girls. I should have mentioned to you earlier I’m on a tight schedule and I have a radio interview in a couple hours,” Sweetie Belle magically floated over a large blue cushion and settled down into it, spreading her legs wide. “I needed to squeeze in some me time before I headed that up.”

The big orange stallion acknowledged the two stunned crusaders and unzipped his pants, letting them fall to the floor to reveal his large, rapidly hardening erection. He walked over to Sweetie Belle’s dripping entrance and easily glided inside. Sweetie Belle squealed happily and clenched her fingers.

“Ah! Ooh! I can meet you girls later in the evening after my interVIEW! Ah! Is overrr,” Sweetie Belle flinched and gasped, massaging her leaky breasts. “Or if you want… stay here with me and fool around? Just for FUH-Funnnn!”

Sweetie Belle tossed her head back and moaned, running her long fingers through her mane as the stallion began eagerly thrusting into her.

“Miss Sweetie Belle doesn’t often have time for these, uhm, situations,” said the petite mare, who was eagerly undressing next to them. “So she has to make do where she can.”

“One second Sweetie!” Scootaloo shouted, unsure if the moaning mare could even hear them. The orange pegasus pulled Applebloom a few steps back from the unfolding orgy. Once they were sure they were in the clear they began to discuss what to do.

“What do you think Scoot? For the life of me ah did NOT expect this to happen,” gestured Applebloom, as the pegasus flew over to Sweetie’s breast and began playing with her fat nipple.

“I… I dunno. I mean like. I’m really hot, I’m sweating like an animal and…” Scootaloo bit her lip. “Sweetie Belle is really sexy now.”

Applebloom gasped.

“What? She’s right! I was only looking through my feathers because I wasn’t sure if she’d be embarrassed without her clothes on,” Scootaloo continued, the sounds of the sex scene behind them intensifying. “Just because we’ve known for years doesn’t make her not attractive now!”

They both turned to watch the unfolding orgy. The stallion was ramming into Sweetie’s pussy at a steady pace, drawing countless squeals and moans of pleasure from the over-sized mare. The fit mare was still fondling Sweetie’s massive breasts, her own smaller tits squished against Sweetie’s large, firm one. The petite Satin Sheets was sharing a deep, heated kiss with Sweetie, who had two of her large fingers shoved deep inside the tiny mare’s wet snatch.

“Wow… she’s certainly uh… skilled at multitasking, right Scoot… Scoot? Whoa!”

Scootaloo had stripped her sweat-soaked top off and tossed it into a ball on the floor by her hooves, her nipples standing at attention and achingly hard in the warm air. Quick as a flash she’d pulled her bottoms off and kicked them off to the side. She ran her fingers through her short mane, exhaled, then glanced at Appleblooms bewildered expression.

“It’s whatever. We’re still best friends. She's still Sweetie Belle on the inside so like... I don’t mind being best friends with benefits,” shrugged Scootaloo, her shapely breasts jiggling on her chest in the open air. “So I’m taking up Sweetie’s offer.”

Applebloom was too flabbergasted to muster a retort. Soon as Scootaloo finished her sentence the lanky mare flew over to Sweetie Belle’s face. They spoke briefly, and in seconds the amazonian unicorn was eating out Scootaloo’s little pussy. The orange pegasus arched her back and grabbed onto Sweetie’s long horn. It was an incredibly erotic sight.

After a minute or so of heavy licking, Sweetie Belle cracked one eye open to look at Applebloom standing there playing with her fingers. The big mare lifted her free hand up and motioned with her finger to walk over.

“...aw horseapples. Screw it,” Applebloom pulled her collared shirt over her head and unhooked her bra, letting her clothes slip to the floor. She sashayed towards Sweetie Belle, heavy D-cup breasts swaying with each step towards her the massive mare.

Sweetie Belle could only grin through her fervent lickings as her sexy little friend walked over to her outstretched hand. She had it all: Fame, fortune, fashion dominance and now she not only managed to retain her friendships, but even expanded upon it with little resistance. A splash of hot juices warmed her big tongue as the pegasus on her face convulsed in orgasm. Sweetie Belle licked her lips and magically pulled Scootaloo off her muzzle, giving her a strong kiss before settling the sexually charged mare on her abs. With her fingers wrapped around Appleblooms thick torso she lifted the small apple mare up to her face.

“What’s up Applebloom? You look nervous.” said Sweetie Belle, noting Appleblooms wide-eyed face and crossed legs.

“Ah-Ah…” Applebloom squeezed one of Sweetie’s massive fingers, and wriggled softly in her grip. “Ah’ve never just felt like… y’know, being picked up before.”

Sweetie Belle gently caressed Appleblooms breasts with her thumb. “Don’t be nervous. Whatever you feel like now, you’re going to forget it,” She brought the small mare close and kissed her softly on the lips, holding her there for several seconds. Appleblooms little hand fell to her cheek and she returned the kiss in kind.

“Wow,” Applebloom panted as they broke the kiss. “Wow,” she repeated, wiping the thing strand of saliva from her lips.

Sweetie Belle chuckled softly. “I have that effect on everyone. I’m just glad I could share it with you and Scoots.”

They kissed again, and Appleblooms voice joined the chorus of pleasured cries in the supermodel mare’s big spacious room.

Author's Note

And that's the end! I hope you enjoyed Envy is Magic! One of my favorite aspects of growth stories is when the trigger is unique and that's how this fic was started conceptually. Feeling envious is the worst feeling, and causing it feels great. It'd be a bit too easy to have the trigger work the way Sweetie Belle first expected it, and I really enjoyed writing the dialogue and scenes where she's goading others. The hardest was actually writing her goading the other two, because even under such a spell I don't think Sweetie would be mean about it. I'm pretty happy with how it continued past that.

Thanks for reading!
