Princess Celestia let out a melancholy sigh as the moon peeked over the horizon at last. Every day for the last year, she’d had to raise the moon with the absence of her sister. And every day for the last year, it only reminded her of how she’d had to banish her sister there.

She’d found ways to pass the time, mostly by privately indulging in her kinks behind closed doors. Yes, she was a princess of Equestria, an immortal alicorn goddess, beloved by her subjects. Yes, she towered over them at ten feet in height. But she was a mare all the same, one with those same gnawing urges that ate away at the back of her mind.

Many of those urges came from the endless string of compliments she was always paid by her subjects. Many of those compliments about the delightfully large breasts that framed Celestia’s chest. Even considering her height, they were huge, as big as a normal pony’s head. At first, she’d simply dismissed the compliments as the normal flattery that her subjects might use to butter her up, but the years upon years of hearing it had finally convinced Celestia to give them some much-needed attention.

Being “large” had always been a fascination of the princesses, Celestia and Luna alike. Besides the simple fact that they were just plain bigger than their subjects, they were the gold standards of beauty in Equestria. And if they were big, then big was beautiful. Celestia had begun to secretly relish this feeling of size, of power, that she asserted naturally over her mortal subjects.

Turning back into her bedchambers, Celestia’s horn glowed with a golden aura as she brought a spell book close to her, one she’d scarcely read save for one page, opening to its bookmark. There, in the middle of the page, was the “Size Shift” spell that she’d memorized.

Since the moon was up, and her doors were locked with the guards standing watch, her obligations for the day were over. Most ponies expected Celestia to be asleep in short order. Now was her chance to finally let off some steam.

With a bright glow, Celestia’s magic flowed through her body, beginning to slowly expand in all directions. Her ample breasts pushed against the fabric of her white dress, which wasn’t putting up much of a fight. A grin crossed Celestia’s face as she felt the familiar rip of her clothing, the magic making her grow bigger and bigger in her chamber.

It was only moments before Celestia’s tits burst through the front of her dress with a mighty “rip,” her huge white breasts bouncing free. The golden bra and panties, her last barrier of decency, snapped off like rubber bands as she grew. For as many times as Celestia felt it happen, she never got tired of that feeling of her clothes succumbing to her growth.

Totally nude, the spell intensified every feeling in Celestia’s nerves, making her shiver with delight as her hands gave those big white tits a good squeeze. She slowly sat on the tile floor, the whole room starting to creak under her increasing weight. Celestia’s head approached the high ceiling, almost thirty feet in height, as she rubbed her smooth white ass against the cool tiles. Even a light bump against her bedframe made the whole thing almost crumble, the spell book flapping wildly as Celestia’s hand went lower.

With one hand still on her breast, Celestia’s fingertip slid down against her folds and began to slowly rub. Her eyes closed as her finger moved, building up speed gradually, whimpering as her thoughts turned far more perverted.

She saw herself. Towering over the entire country of Equestria. The trumpets were blaring and the crowds begging to worship at her hooves. Mare and colt alike sat in awe of her presence. They were overwhelmed by the mere sight of her beauty. Even the pegasi flew from their clouds just be close to her breasts. Hugging as much of those beautiful tits as they could.

With a playful grin, one of Celestia’s hands, big enough to hold the town of Ponyville all by itself, gave herself another squeeze. She trapped the hundreds of pegasi deep against her tit. Despite the power of the sun princess, not one of the pegasi was hurt. Not that any of them was about to complain, anyway.

As Celestia’s eyes flickered open and closed, the bed shook, the floor rumbled and the vase against the wall toppled onto the tile with an audible crack. It was enough to send Celestia out of her euphoria and back to reality. One where she was a little too big for even this royal-sized bedroom.

Celestia let out another sigh. Her horn glowed as she shrunk back down to normal size, not bothering to reform her clothing just yet. She stood up only to slump down on her bed a moment later, resting her chin in her hand. Her magic reformed the vase, but Celestia didn’t even bother to look at it.

That had always been the worst part of this growing need, this urge, this… kink! The inability to act on it!

Celestia had known for the longest time that how big she became in her bedroom wasn’t near as big as she could be. She really could apply her magic to become that goddess that towered over the landscape if she wanted to. It would be easy.

But she couldn’t do it if it meant becoming a threat to her subjects. She was already stronger than any earth pony. The cosmic strength she had was a danger to her entire kingdom should she exhibit even one-hundredth of her real strength. The thought of somepony hurt because of her need for this release? As bad as Celestia wanted it, she had the self-control to hold herself back for their sake.

With the vase returned to its table, Celestia’s head dropped, her eyes catching a glimpse of the spell book. During her bliss, the pages had fluttered open to one Celestia hadn’t taken the time to read before. One word on the current page caught Celestia’s eye:

“Harmless.”

True, Celestia had just skimmed the rest of the spells – there was only one spell in the book she ever cared about, after all – but her thoughts compelled her to take another look. She levitated the book into her hands and read the spell’s effects out loud:

“Harmless – Renders the target temporarily incapable of causing harm. Physical force is magically dispersed and blocked by the spell. Objects are also unaffected. Target still capable of… feeling…”

Celestia trailed off at the last few words. If this was what she’d been looking for all this time, then it needed casting. Immediately.

With a quick read of the incantation, Celestia’s horn glowed a bright gold, aiming the spell at herself. The magic flowed back down into her, sending a sharp tingle up her spine, her wings sharply flapping out to her sides and her back arched on instinct. A few flaps of her wings brought her back down, taking a few deep breaths to calm herself.

Taking a look at her hands, Celestia looked for any signs of an immediate change, something to show that this spell had worked. But, despite checking every inch of her tall frame, there was nothing obvious.

“I don’t feel any different, either…” she thought. But it needed a test.

Celestia stood from the bed and made her way to the vase she’d fixed moments before. Curling her hand around it, she pushed the vase into her mammoth tits, her nipples rubbing against the smooth ceramic surface. A smile curled across her face as she began to press it harder against her chest, the ample breasts almost as big as the vase itself. She’d already begun to quietly inspect the vase for any signs of cracking from rubbing against her immenseness, and found none. It was time for a little more pressure.

Celestia grabbed the vase with more of her alicorn strength, gripping it harder and harder with the kind of power that could move a mountain from the earth. Nothing.

She slammed the vase against her own impressive mountains, squishing and squeezing the vase between her tits until her softness has rubbed over every inch. Nothing.

Finally, she outright grit her teeth and grabbed at the vase with all the strength she could muster. She braced the smooth surface against her titanic mounds. The power to tear worlds asunder behind the arms of the goddess pulled on the vase. Divine might that could rewrite the stars in the sky and rip reality apart was being pulled into this one tiny pot. Her breath grew faster and sharper, her eyes darting across the vase.

Still nothing. Not even a scratch across the surface.

“UNH!” cried Celestia, beside herself with delight as she dropped the vase to the floor. It bounced away across the tile as she smiled from ear to ear, even grabbing her voluptuous tits in her hands.

“Yes, yes, yes! That’s it! This is it!” She felt an ecstasy even greater than when she’d run her fingers across her folds moments ago, her mind rapidly swirling with that same imagery. Those lovely sights of herself as a titan, basking in her sunlight, worshipped by all who looked upon her. Worshipping those enormous tits the way they deserved to be.

Her moment of bliss was interrupted by a sudden slam from her bedroom doors, kicked open by a guard with his sword at the ready.

“Your Highness! Are you alright? I thought I heard… I-I…”

He knew instantly that it was wrong to stare at the beautiful, naked frame of an alicorn goddess. But nothing was letting him look away. The blush washed over his face as he simply stood, lock still, facing his princess. His arm slowly fell to his side, the sword’s hilt slipping from his grasp and clattering on the tile floor. Celestia’s grin somehow went wider still as she lowered her arms, her massive tits jiggling into full view.

“Guard?” she whispered, closing the doors and magically reforming the lock behind him. “Come closer. I have special orders for you…”

Pledge Shield had hardly thought, on the day he joined the Royal Guard, that one of his assignments would be being smothered under the enormous white tits of Princess Celestia. More so now that she’d grown to over three times her already impressive height to thirty feet tall, pushing her tits against him like he was about to be crushed with the slightest slip. Celestia was almost bouncy the way she pushed him down against the floor, over and over, never letting up for even a moment of rest.

Not that Pledge Shield was about to complain.

He was humping his thick cock up into Celestia’s tits, more aroused than he’d even been in his life before, the haze of lust clouding his mind against everything but those godly breasts. Celestia had kicked her legs against her bed, the wall, the furniture, everything, and not a bit of it had moved out of place. And the more she kicked, the harder she pounded. For one fleeting moment, Pledge Shield wondered how he wasn’t being crushed by the power of the alicorn, and it just as quickly slipped away as he was floored again by the monstrous tits.

“Nngh… now, Pledge Shield, I need you to be honest… aah! Mmh! How do you feel?” said Celestia, trying and failing to stifle her obvious excitement, leaning over her huge chest to watch the guard lose himself to his lust.

“I-I feel… I f-feel... unh! UNNH!” he stammered, unable to form one coherent thought while he grabbed onto Celestia’s massive rack, humping with everything he had, sweat rolling down his face.

Celestia, meanwhile, couldn’t stop grinning. “Good! Because you’re going to get everything now!”

Her horn sparked as her body swelled, growing even further. Even as her plump, round ass pushed against the wooden bedframe, and her long smooth legs pushed her ever-increasing weight into the floor, nothing moved. Nothing cracked. Nothing broke. The sight was more than enough to give Celestia the confidence to further boost her already gigantic frame bigger. A few moments, and she’d be forty feet tall standing. Then fifty… then sixty! It was getting cramped for Celestia in her bedroom, keeping herself at that size when she felt her body touching all four walls, her horn scraping against the ceiling.

All the while, Pledge Shield was buried under her silky pair of gigantic breasts, disappearing beneath them entirely. Celestia couldn’t contain herself any longer. She raised and pushed her tits down against the guard with all the strength she could muster. She’d finally begun to feel like a real goddess at this size. Her massive form was limited only by the walls of her castle. Her mind raced again. Her pulse quickened as she felt her body tense.

Celestia felt the heat growing quickly between her legs. She pushed one of her hands into the floor near her titanic tits while the other clamped over her mouth. Her moans and grunts kept rising all the same. The brush of the cool tile against her hardened nipples. The guard’s cock pumping with soul-consuming need to fuck those beautiful tits. Her perverse urges from millennia of waiting and wanting this.

It was all finally too much.

Celestia screamed into the palm of her hand. She visibly shook in ecstasy as her nethers leaked a heavy stream of her cum over the canopy of her huge bed, drenching it in gallons of the stuff. Her hand pushed into the wall, the spell preventing the giantess from causing an earthquake from the seemingly endless pleasure that shot through her body.

Even with her hand stifling her bliss, Celestia’s grunting and moaning felt like it took eternity to finally end, over a full minute of a sensational orgasm making her spasm against the walls of the tiny bedroom. Celestia’s scent filled the air as she collapsed down onto the floor, panting for breath. Her bed was probably never to get that aroma out completely, and even gushing over her bed did little to stop Celestia from creating a puddle on the floor.

“Nnngh… My word, that was… That was incredible!”

She finally pulled herself up, her horn poking into the ceiling once again to remind Celestia how big she really was. It took her a moment to remember the guardsman she had buried beneath her tits, which were still jiggling and bouncing with even the smallest of movements.

“Pledge Shield?”

No answer. For a moment, Celestia wondered if the spell she’d found might have worn off, and she’d crushed the poor colt. She quickly shrunk herself down back to the height of thirty feet, only to feel the underside of her breasts coated with a sticky warmth.

Below Celestia, the guard had passed out, his cock still fully at attention for his princess, the massive load from his balls still gently dribbling out its dying drops. The intensity of the pushes from Celestia’s tits had been the closest to Heaven a mortal pony had ever come before.

Celestia’s eyes slowly moved from the passed out guard to the window frame, which overlooked a vast valley and long mountain ranges.

The smile on her face was almost as bright as the sun itself.

“Hurry up!” cried Paper Crane, frantically flapping his wings as he attached the long line of flags above the town’s lamp posts. “She’ll be here any minute!”

The entire town of Whinnydale was abuzz with the last preparations for the arrival of Princess Celestia. The unicorns put the finishing touches in the large banner that hung across the town square, hovering it into place while a few pegasi clamped it down nice and tight.

“How in the hoof do these things always come down to the last minute every year?” Paper Crane cursed under his breath, tying the end of the flag rope to the last lamp post, brushing his matted white mane away from his light blue eyes as he fiddled with the knot.

Especially this year. Five hundred years since their beloved princess had sealed away Nightmare Moon and saved not just Equestria, but all of Equus from the dark tyrant. They wanted to get everything just perfect for Celestia; this was going to be her first stop on her trip across Equestria, and Paper Crane had been tearing his mane out trying to make it her best stop, too. It was only figurative mane-tearing, but he was edging closer to literal as the minutes counted down closer.

Anticipating Celestia’s imminent arrival, the crowds had gathered, and the only one still roaming the streets was the frantic Paper Crane. His meticulous detail of exactly how tight the knots should be tied was interrupted by a brief but very clear rumble in the earth. The pegasi hovered above the town, watching as their buildings slightly shook. Gradually, the low rumbles in the earth below their hooves got louder and louder.

Paper Crane felt his heart sink in his chest. For all of his nerves, he could now hardly even keep himself airborne.

“That’s her!” he shouted to the assembled crowd. “She’s here!”

As she came around the bend in the mountain, the first sight of Celestia began to come into view.

And there was a lot of her to view.

With the combination of the “Harmless” spell and her beloved growing magic, Celestia had become a magnificently tall titan. Even the mountains she’d passed around couldn’t completely contain Celestia as her hooves drove themselves, step by gigantic step, over the landscape. Without a stitch of clothing or a stud of jewelry to cover her godly form, the massive body of Celestia was on full display to everypony in Whinnydale. And for miles more in all directions.

What they were all staring at were those beautiful tits, mountains in and of themselves, bouncing freely across her chest. At this size, even the tiniest movement of those tits was like hours of vibration hitting her all at once. It was all Celestia could do to keep herself composed, even if her marehood below was already dripping in small bursts down her inner thigh. Even on her approach, the tempting, tantalizing aroma was impossible to ignore.

A smirk across her face betrayed Celestia’s mood as her long strides bent the trees, shook the rocks and pushed the clouds away from her smooth coat. She glanced town at the small town below to the tiny citizens who were cheering her in welcome, her hooves gliding over the tree trunks, bending to and fro back into place like they were made of rubber.

Paper Crane’s cock was already threatening to rip right through his pants as he stared longingly up at his princess, and he was far from the only one. Several ponies had already stuffed their hands down their pants, fixated on Celestia, who was at least a few miles in height. With a determined shiver, Paper Crane managed to compose his thoughts long enough. Just for a minute, that’s all he needed…

“Welcome, Your Highness!” shouted Paper Crane up to the towering alicorn. “It’s always a pleasure to… nnnnnnngh…!” He felt his cock throb with another inch against the straining fabric, just begging to be released. “Pleasure to see you!”

“It’s a pleasure to see you, Paper Crane,” said Celestia, her voice booming down across the tiny village. “Now… I know this is the five hundredth celebration, and you must have worked so hard to impress me, the way you always do. Whinnydale has always been one of my favorite stops on my tours of Equestria.”

“Thank you, Your… Highness…” Despite his obvious arousal, Paper Crane was prepared to go through with their rituals. Praising of Celestia, her beauty, her love, her compassion, her protection for all of ponykind. Even the griffons and the dragons that despised her couldn’t think of competing against her, with the “visits” Celestia made to them more than enough to change a few minds.

Paper Crane slowly raised his hands and inhaled to start his praises, but cut himself off as he saw Celestia’s massive hand signal for him to stop.

“I know you’ve done so much. And you truly are all wonderful for putting in such hard work. But, I think we’ll just skip the ceremony this time…”

There wasn’t a chance for a rebuttal. Celestia began to kneel.

Her head tilted back and the smile across her face spread, those beautiful breasts descending from on high towards the town. Most of the townsfolk quickly ripped their clothes off as they saw them getting closer, and the few that didn’t still weren’t moving, awaiting the smothering of Celestia’s titanic breasts in a few moments. The more impulsive and impatient pegasi didn’t even wait that long, flying high above the clouds to reach Celestia before anypony else could. Paper Crane remained firm on the ground, finally unzipping his pants to let his strained cock spring free, grabbing his dick and rubbing while he watched a nipple wider than a few city blocks slowly move right towards him.

Celestia’s hands spread to the roads outside of town as she reached her knees, the low rumble from the earth the only resistance thanks to her magic. Ever the tease, her tits came down slowly, even for somepony her size, edging closer and closer by a few feet with each passing moment. Those impatient pegasi were rewarded by being pushed back down through the air by the sheer might of Celestia’s boobs, though many had simply grabbed onto her coat and started thrusting against her.

And she felt it. She felt every little push, thrust and hump by her subjects, shivering as her folds began to drip feed a steady fountain. She couldn’t help but lower herself down faster, the ponies on the ground getting eyes full of white and pink flesh as she drew ever closer. The anticipation was too much for Paper Crane, who was furiously jerking himself in the middle of the street, unable to take his eyes away. Even with all the times she’d smothered him before, each one was better than the last, and his lust for the goddess simply wouldn’t let him wait.

Paper Crane and the others on the ground managed to get even faster as they saw the first tops of the cabins and cottages be touched by Celestia, her magnificence pushing past each of them without breaking a single splinter out of place. She was already moaning and shuddering above, the pegasi’s humping giving her all the incentive to just push down and slam her tits into the streets and horny ponies below. Her enormous white hands curled into fists as she finally had those breasts touch ground, smothering all of Whinnydale beneath them.

Despite being buried under literal tons of flesh, Paper Crane grabbed onto Celestia’s nipple and began to slam his cock upward in earnest. A few of his fellow townsfolk were already cumming, gushing their loads into Celestia’s tits as she covered the city. Her mountainous tits jiggled and bounced with incredible force, their warm releases still sending more shivers up Celestia’s back, her wings uncurled high into the air and her bulbous ass jiggling skyward.

“Ooh, you’ve-mmh!-been practicing, haven’t you?” Celestia said, stifling her moaning for just a moment, biting her lower lip. With the slightest bit of her might, she pushed her tits down harder against the town, covering them more and letting them feel the incredible weight of the tits she’d trapped them all under.

“Unh! Yes, Princess! Yes, yes, YEEEEES!” shouted Paper Crane, his cries of lust muffled by the nipple that covered him. His hands grabbed at the nipple while his cock gushed his load, keeping on a tight grip while his tongue licked across the huge areola. The last bit of decency faded from his mind as he lost himself completely to his passions, madly slamming his cock up into Celestia’s warm boob, feeling his emptying balls already starting to refill.

Celestia felt every load that splattered against her tits, the tips of the cottages and cabins below providing even more pressure on her fat breasts, her nethers gushing a steady stream like a waterfall onto the forest. Her eyes closed, her hands gripped tight against the earth, raising and lowering her breasts down onto the city, never moving them entirely off the ground. Her quick, rapid breaths and her guttural moans could he heard across half of Equestria.

The townsponies were in a blissful nirvana, most on their second orgasm and many approaching their third, mare and colt alike. The heat of her tits was blissful, the pressure felt incredible, and the aroma of this beautiful alicorn permeating every breath. Sweat rolled down their bodies as they refused to stop humping their way against Celestia, many of them content to keep going until they’d passed out.

Paper Crane could feel his cock growing even bigger as he slammed it into Celestia’s gigantic tit, the thick black dick of the horny stallion swelling in size and length the longer he rammed it into the soft whiteness. His second orgasm lasted even longer than his first, gushing a load of cum unlike anything he’d ever released before, already feeling a third starting to swell up in the base of his growing cock even before his second had completely stopped. The magic of his goddess wasn’t about to let him off so easily, making his tired balls swell again as he still wouldn’t stop. Paper Crane screamed in ecstasy, one of hundreds that were buried down below the tits of their beloved princess doing the same.

Celestia herself wasn’t faring any better. Her grunting and moaning echoed throughout the region as her tits played with the town. The heat of her sun high above brought Celestia that much closer, the earth beneath her rumbling once again as she squirmed in delight. Her folds were still leaking gallons upon gallons as she was brought closer with each passing second.

“UNH! That’s it, my ponies! Don’t stop don’t stop don’t stop don’t stooOOOOOP!”

Her entire body tensed as she felt the inevitable approach. She leaned up one last time to slam her breasts down upon the town as hard as her godly strength would allow her. The force of Celestia’s muscles could have allowed her to rend the planet asunder with nothing but her tits. Yet all her beloved subjects felt was the overwhelming sensual pressure that smothered them harder than ever. Even the mountains behind her appeared to sway slightly despite her spell.

Paper Crane’s grip waivered. His entire body shook. Everything told him to ram those tits. Ram them forever if he had to. Like he was never going to stop. Because he never wanted to stop.

Celestia felt it.

She felt every last thrust. Every last hump. Every last lick and nibble and perverted slam. She felt every cock that swelled beyond its limits in an effort to pleasure her. She felt every horny mare and colt ram into her tits with all their strength.

At last, for the gigantic goddess, her bliss came to a head.

And she let go.

Celestia’s lustful screams of passion sounded across the skies as her folds drenched the land below. Thousands upon thousands of gallons of her cum flowed from the alicorn like a river. The clouds flew away from the power of her voice, the flow beneath her washing over the forest floor in a massive wave.

As if on cue, Paper Crane’s third orgasm rocked him, sapping what little energy his body had left with his engorged cock blasting a load bigger than his first two combined against the tit he was pushed beneath. He screamed out a praise to the goddess on high as his balls finally emptied, their growth having brought his massive orbs down to his knees.

Only after what felt like an eternity of bliss did Celestia finally allow herself to rest. She collapsed her tits on top of the town, gasping and panting. The aroma of sex permeated the air for miles, and would stay there for weeks. The ponies below in Whinnydale were finally coming down from the incredible sexual release, some of them having fainted from orgasms the likes of which they’d never felt.

Collecting her senses, Celestia slowly began to lift herself free of the town, pulling her gigantic tits upward. Her eyes opened once again, glancing down below to see Paper Crane and his newly engorged cock, the tip poking past his chin as he licked it gently.

“P-Praise Celestia…” he whispered in between the kisses and licks to his own flared tip. “All hail the… nnnngh… the goddess of the sun…”

Celestia chuckled, despite herself, her massive tits covered in the juices of several ponies. “I’m happy to hear you enjoyed yourself. That was your town’s best showing ever, by far.” She got to her hooves as she slowly stood up to her full magnificent height, her folds still dripping wet.

“But, I’m afraid that our time together is over, my little ponies. I have to get myself cleaned up before my trip to Baltimare. They do expect so much of me down there…”

Author's Note

The next few chapters will have a little less set-up than this one did.

Onward!
