Rainbow Dash was bored.
It's not that she didn't like being queen. Her subjects were so scared of her after her ascension that every interaction was a mini power-trip. The stammering, the frantic bowing, the fulfilment of her every whim... it was exactly what she deserved.
It had been an interesting few months.
The country was mostly repaired. She had done that with her magic- what was the point of being Queen of a ruined country? Canterlot was no longer flooded with her ladycum, no longer ravaged by her gigantic claws.
Mostly.
Ponies had to remember who was in charge.
Her subjects were all back, too: she had teleported them out of her belly once her fun was over. Against all odds, they were fine, and of course completely loyal. Dash wondered if Celestia and Luna had ruled mostly through fear back in the day. It sure worked.
Speaking of the princesses... those she had kept. Their magic was hers forever, now.
Power coursed through her twelve-foot blue griffon form.
Because that was the thing. No longer was the Griffon Queen a titan large enough to use Canterlot Mountain as a fuck toy. After doing just that, the potion's effects had just sort of... stopped making her bigger. In fact, she had slowly shrunk smaller and smaller until stopping at around twice Celestia's old height. If she was honest with herself, she knew this was nothing but a good thing. She's get bored even more quickly if she'd remained too big to interact with anyone else on the planet, or worse, outgrown the planet itself and been drifting in space forever....
She shivered at the thought- but not in an altogether adverse way. In fact, she was a little turned on.
"Attendants!", she called. And grinned as the attendants came. Six ponies, three stallions and three mares, all there to serve her and only her.
"Yes, my Queen?" one said warily. Dash had chosen these ponies, not for their subservience, but the exact opposite. They were ponies who did not want to serve her, but knew that the other choice was a far more terrible fate. On top of that, Dash knew that they found their queen incredibly sexy despite hating being forced to serve her. Their bodies betrayed them: already the huge griffon could see one of the stallion's masts rising despite himself.
"Rub me."
The order was carried out immediately. Dash laid down on the floor of the throne room, stretching herself out. From her feathered chest to her enormous lion's paws, she was longer than five ponylengths.
She sighed as the attendants went to work. Her neck, her back, her ass, her legs, her belly and- most importantly- her moist sex were all being slowly massaged by dutiful little hooves.
Oh, they were so small.... and she could make them smaller.
She looked down at them. The stallion rubbing himself against her legs was fully erect, and blushing with clenched jaw. She playfully wrapped her tail around him- it was thicker than his shaft, and she chuckled. She loved having her legs rubbed, but even better...
"You. Get on top of my paw."
"On... top of it, my Queen?"
"Yeah. Get on top and grind, big boy. I want to see you sweat."
He reluctantly stopped rubbing himself on her powerful thighs and trotted to her paw. It was huge, the size of his entire body, and a gentle flex from Dash revealed claws the size of daggers, only for a moment. He positioned his body over it and began to press his cock into the warm blue fur. Holding back a moan, he let his body sink into the paw and began to hump.
Dash closed her eyes. The feeling of the horny stallion going to town on her- and not even her, just a small part of her, a part that almost matched a whole pony in size- was just her kind of feeling.
"You." She addressed the mare rubbing her lioness pussy. She had been going slowly, gently- that was how the Queen liked it. "Get in there."
With a grimace and a nod, the mare ducked down to Dash's clit and began to lick. Her soft lips met much larger lips of a different kind, and Dash humped slightly with a grunt, pushing the mare's muzzle into the folds. She was ready.
Her unicorn horn lit up, and the ponies massaging her back and neck were lifted into the air. They knew what was coming, and braced themselves. The stallion looked angry. The mare looked resigned, but tense. Dash held them in front of her in the air, thinking about how powerful she was, how big she was. The stallion's cock was only partially erect. With a sly grin, she began to fix that. He moaned through gritted teeth as she stroked him with her magic, revealing his two-foot rod. Then, an idea.
Like a couple of toys, she brought the mare and stallion together in the air, putting his cock against her swollen folds. The mare gasped slightly. She was already wet from massaging the Queen's powerful back muscles. She could do nothing- neither pony could- as the huge cock was forced into the waiting marecunt. Both of them moaned, louder now, as Dash relentlessly pushed the stallion into the mare until he was fully hilted. Spinning the panting little ponies around, she looked into the mare's eyes, and began the real fun.
The mare's eyes shrunk to pinpricks as the mare herself began to shrink.
It was something Dash had figured out how to do all on her own. Who wanted to read egghead spellbooks? She had all the power she needed to cast her will onto the world by brute force. It was the fate of the princesses. Shrunk to nothing as Dash laughed.
And now, as the mare became smaller around the huge shaft within her, Dash slowly began to grow.
The potion wasn't working any more, but it turned out Dash could have all the size she wanted if she stole it.
A few seconds went by, and the Queen's form stretched a little longer on the polished floor. The grunting stallion on her paw felt the mass beneath him flex and swell. She let the sensation last a few seconds, then stopped.
The mare was now the size of a teenage filly. The cock was huge inside her; tears leaked from her eyes as she felt the reluctant twitches of the stallion's lust. With a thought, Dash stroked the stallion again. His instinctive clench made the mare whimper. Dash shrunk her a little more. She cried out as the cock became monstrous within her, distending her, filling the tiny filly-sized pony completely. Now tingling again from another few inches of growth, Dash began on the stallion. He groaned as he began to shrink, too- but not all of him. His cock didn't get any smaller, and the mare continued to pant and whine as the Queen got bigger and the Stallion quickly became the size of a colt. Now the ponies were truly helpless. A colt-sized stallion with a cock as large as either of them, shoved to the hilt inside a tiny twitching cocksock.
Dash dropped them to the floor, and felt how small the other stallion had become compared to her lioness paw. He was still grinding, but no longer did he have to crouch a little. In fact, his front end was resting on top of her toe as he grunted his efforts into her. The paw was officially as big as he was.
The Queen grinned and used her magic to push the other mare's head more firmly into her larger cunt. The mare complied, pushing her muzzle deep into the aching folds. Dash picked up the paw-handler, as well as the remaining two ponies in her magic and considered them. None of the three would meet her eye. Shrugging, she concentrated-
And all three began to shrink.
Dash moaned as her form stretched more and more. Smaller and smaller they shrank, and bigger and bigger she swelled.
"Yes... Bigger..." She panted. By the time she had taken them down to the size of foals, she almost reached the edges of the throne room. For good measure, she shrunk the coupled pair down to foal-sized also- the mare cried as the cock became twice the size of her whole body, still inside her- and stood, leaving the last mare on the floor for now and considering her shrunken attendants. She could fit all of them in one talon. She stood over twenty-five feet tall. Her wicked- sharp lioness claws were each as large as a pony's leg. The normal-sized mare jumped as Dash demonstrated this, and then yelped as she was picked up in the Queen's magic. Dash held her up to her enormous eye.
"Time to go in!" The mare braced as Dash flopped onto her back with a room-shaking boom and pushed the little mare, headfirst, into her waiting cunt. Exactly the right size, the mare slid in with almost no resistance. Frowning, Dash clenched her inner muscles. "Come on! Squirm!"
The mare complied, and began to wiggle and thrash in the way the Queen loved. She clenched again, moaning as her massive form made the room rock with its twitches.
It didn't take long for Dash to come. Fluid gushed onto the floor as her tail thrashed and her lion claws left deep scratches in the polished stone. Then, panting, Dash used her magic on the mare within her once more, pulling her in, forcing her more deeply inside her until she rested in the giant's womb.
Then, she stood up, and directed her attention to the tiny attendants beneath. She gripped them in her magic, and concentrated again. They began to grow, and she began to shrink.
The afterglow of her orgasm made the Queen grin as she felt her belly grow heavier. As the ponies before her grew to their normal size, she shrank back to hers. By the time she was only twelve feet tall again, the mare within her made her heavy with what looked like a nearly full-term pregnancy. The attendants were visibly relieved to have their size returned to them, but also disgusted and angry with their new lot in life. They knew better than to say a word, of course. The stallion's flaccid cock slid out of the shaking mare with a schlick.
"Alright, get out of here." The queen turned and walked back to her throne as the five ponies trooped away. She reclined, rubbing her captive idly as she mused. Terrorising the poplace was kind of fun. She should do that later. In fact-
"My Queen!"
An elderly stallion ran into the room, holding a couple of scrolls aloft in his magic. "The dragons! The Dragonlord! He means to attack Equestria!"
Dash perked up as the stallion halted, staring with shocked fascination at her apparently-pregnant form. "My Queen, did you-"
"Dragonlord, huh?"
The stallion started and looked back at Dash, unrolling one of the scrolls. "He means to take Equestria by force. Apparently a small drake brought him news that the princesses are... eh... no more, and seems to believe that they were defeated by some monster or... um." He flinched a little at the Queen's raised eyebrow.
"Well... we'll just have to show him how awesome a monster I am." Dash pointed at the door. "Go find out more about this "Dragonlord". I'm gonna make a plan."
He scurried out. She lazed back in the throne, grinning now at a world ready to amuse her some more. No doubt she had the power to fend off any dragon, but... what should she do just in case?
It all came to her in a flash. Twilight's lab. Where this had all started.
She teleported the mare inside her a few feet away. She collapsed onto the floor, dripping in the Queen's inner fluids. "Get out of here", said Dash. The mare ran out, shaking, after the old stallion.
Dash didn't spare her a glance. Her mind's eye was filled with the box of potions beneath Ponyville... and the flask it contained marked Dragon.
...Dash hit the floor with a resounding thud.
Looking down immediately, she saw that she still had her birdlike talons, though they looked even tougher than before. Blue feathers still ran up her forelegs onto her back, and she ran a talon over her head to feel feathers there as well. Her horn was still there; it seemed absorbing alicorn magic made some things permanent. So far, so familiar. But feeling her face was a different story: she still had a beak, of a sort, but rather than being short and sharp, it was more of a long, hard beak-like maw with wicked serrations that might as well have been razor teeth. It grew out of a short, scaled muzzle- the feathers on her head ended between her eyes, and from the face down, it was the hard, scaly armour of a dragon.
Dash shivered as the ran a talon down her chest, the light blue, banded scales feeling so hard and smooth she could hardly believe it was her. She stretched her wings, then, and saw that they were just as feathered as before, but even more massive, with sharp spiny spikes at each joint. Rubbing the back of her neck, she felt similar spines growing out of the feathers, and craning her head around she saw dark blue spines, big ones, rising out of her spine between her shoulders, wings and all the way back to the base of her tail.
Swishing the tail now, she saw it was now scaly; it was as thick as a dragon's tail at her rump, but tapered quickly to its slender leonine form and ending in the familiar prismatic tuft of fur. The hard, blue scales like those on her face gradually took over from her feathers at her ribcage, and rather than draconic legs and claws, she instead saw essentially exactly the same lion body as before, but scaled instead of furred. Her claws were larger, though, and looked permanently unsheathed, the way lions appear in nightmares.
Dash grinned, admiring the way her banded scales ran all the way back to her tail, her leonine form only made more intimidating by the scales, her cock and balls imposing on her-
Hang on. My what now?
And now that she noticed, it was impossible to ignore. All of the arousal that had been put on hold by the transformation came flooding back, and as she watched in amazement, her new shaft rose to attention, slapping her scaled underbelly and making her shiver and moan involuntarily.
No time to wonder about this. I have a dick now. Awesome.
Trying to ignore it for the moment, she looked around. She didn't seem to be any bigger. But that was the same as the first time, wasn't it? To start growing, all she had to do was...
Hnnnggg...
It was like nothing she'd felt before. The feminine need, that was still there, her pussy clenching as strongly as always, hungry for something to fill it up. At the same time, her cock twitched and throbbed, and Dash wanted nothing more than to wrap her talons around it and rub.
Rainbow Dash stumbled over to the wall, and rose up on her hind legs, thrusting one talon forward against the wall for balance while her other talon desperately grasped her enormous member. It was more than a ponylength long, maybe even two. Dash had a sneaking suspicion that two of those potions had been enchanted for male species. All thought went out the window, though, as she began to rub.
Precum shot out immediately. The huge hybrid's eyes rolled up into her head as she pumped faster, feeling something inside herself ignite, just as it had those months ago. Sure enough, the huge cock throbbed bigger in her talon, now almost too much to handle, smacking against the wall in front of her.
"Bigger...." moaned the queen. Realising she didn't even need the balance, still rubbing, Dash took several steps backwards, and stood on her hind legs in the center of the throne room, wondering why she had never realised now natural the stance felt before. Now, both talons were free to service herself.
Grasping the huge member before her with everything she had, she redoubled her efforts.
"Bigger!"
As she pumped and rubbed, her scaly back paws grew larger and deadlier. The growth quickly spread to her legs and tail, and Dash gasped.
"BIGGER!"
Her talons grew next, allowing her to finally give her dick a real seeing-to. She squeezed and pumped, feeling her shoulders widen and back explode with length. Suddenly she was looking down from a lot higher; her legs and back now much longer, her claws digging into the polished stone as it all built up to-
"BIGGER!!!!"
And her whole body clenched with her orgasm, the screaming draconic griffon exploding with the final stages of growth, her head banging against the forty-foot ceiling as she grew tall enough to rub against it with her shoulders. Cum erupted from her dick, shattering a stained-glass window with its force, and spraying like a hose into the courtyards below.
Falling forward onto her talons with a CRASH, Rainbow Dash panted as the orgasm subsided. She had had a lot of unique experiences recently, but that... that was something else. Looking around at the ruined window, ruined floor, and ruined ceiling, she ran her tongue along her serrated beak, guessing that she was about thirty feet tall now. Already, most of the dragons in the dragonlands would have a hard time measuring up, if she were to guess.
"So how about more...?"
Dash forced her way through the former window (pushing through the stone with her shoulders with ease), jumped into the air, and hovered there, her massive wingbeats rattling the shingles of the roofs below. She looked hungrily toward the dragonlands.
"Dashie want more...."
Author's Note
Yeah, yeah, I know... there was only supposed to be one more chapter. But sorry guys, the anticipation and the too-big-for-the-room parts are my favourite, so I'm not rushing them just to get to the part this fic is supposed to be about.
In the final chapter, expect the kind of hyper-macro you idiots seem to love. At least dragon greed makes it more interesting.
Rainbow Dash didn't go to Ponyville herself, of course. Instead, she sent a few of her subjects- ones she knew she could trust, since they were under extremely powerful mind control spells- to gather all of the contents of Twilight's former lab and bring them to her palace in Canterlot.
Now, she looked down at desks, bookshelves, boxes, some boring-looking metal equipment.... and a wooden crate containing the only thing she cared about.
There were fifteen potions left, all still neatly labelled. She sifted through them quickly. There seemed to be two of each of the pony races... one of each of all the rest... No, hang on. Dash lifted a potion to eye level. Sure enough, the it read "Griffon".
There was another one of these? Dash wondered. Huh... she must have had a reason. Whatever. Setting it down for now, Dash continued sifting... and was once again surprised at what she found. Two more potions were inspected up close by a predatory eye: she was right. There had been two of each pony race... two griffon... and two Dragon.
A moment passed where Rainbow Dash was lost in thought. So what's my plan here? Desert my griffon form for a while, go have fun as a dragon, and use the other potion to change back? It sounded good. Dragons were awesome and all, but she had a sort of... affinity for the griffon body. She flexed her claws and swished her tail in contemplation.
I wonder how big this will make me this time. Her breath almost caught at the thought. I'm already a lot bigger... and dragons can grow ten times as big as I am now without any help at all! In her mind's eye, she saw herself, a titanic blue dragon, growing so big that she began to crush the mountain she sat upon.
She shivered, and felt herself clenching down below. Yeah, we're doing that. Snapping back to reality somewhat, she regarded the two dragon potions before her. Two. The two... potions...
Hmmm. It was a thought, all right. As far as she could guess, these potions contained way more magical power than the silly little alicorn princess had intended. One had made her a titan, for a while. So two... Eyes widening, she lifted up the other potion, the one labelled "Griffon". Or three...
Rainbow Dash was definitely breathing heavily now. It was probably her imagination, but she could feel the power contained in the flasks held in her magic. She knew it might not work like she was imagining. She knew it was reckless, maybe even more reckless than her original theft of the original potion. But look where that got me.
It was too much. Rainbow had never had a lot of self-control to start with, and becoming queen of all Equestria- soon the world- hadn't helped. This was happening. But she could at least try to be smart about it. Mixing them was a bad idea. There was no telling what effect it would have, if any. Dash had been toying with magic for a while, though, and as several hapless subjects had discovered, the queen was more than willing to... experiment with her brute-force method of spellcraft. Dash was pretty confident in her ability to combine two things into one thing, even magical items. Why not try it here?
Starting with the two dragon flasks, Rainbow concentrated. It was surprisingly easy: she could feel the enchantments entangling, and with a pop, Dash held only a single flask. Smirking, she now held the hopefully-double-strength dragon potion next to the griffon one and concentrated again.
This one was harder. The enchantments didn't want to go together, there was a... difference in the... magical... it wasn't working. Narrowing her eyes, Rainbow Dash really focussed. There was something to feel out... each enchantment had two components, a simple one and a complex one. The simple one was the same in both flasks (though much stronger in the dragon flask); she sensed they would go together easily if not for the complex pattern of spellweave in the other component, which was different in each. So... hang on. The complex part must be the species thingy, if the rest of it is just the transformation spell. That made sense, right? So all she had to do was make... the patterns... mesh...
pop.
"HA!" Dash triumphantly held aloft her new potion, which was hopefully now a supercharged potion of transformation into a super awesome dragon-griffon hybrid.
Just then, her informant entered. "My Queen! Just as you asked, I have all the information we have about the dragonlands, dragonlord and-"
"Don't care, get out."
Dash shoved him out the door and slammed it, not taking her eyes off the potion. Her tongue ran across her beak hungrily. No point in putting it off any longer.
Throwing back her head, she poured every drop of the potion down her waiting throat.
Grinning, tensed in excitement, and already horny, the twelve-foot griffon felt herself lift into the air...
