Chapter 1
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.
