A growth-lusty romp through tiers of Hyperquestria pony size.

Saw one of Frostbound's excellent renders and felt a flash of inspiration.

I present to you a tale of tiered pony sizerot straight from Hyperquestria, in a growth-lusty romp that follows Pinkie, Rarity, Dash, Twilight, and Fluttershy through increasingly excessive levels of hyper/macro, with various other excesses drizzled on top to give them each a unique feel. The size tiering was determined by my patreons.

Here I've posted the first 1400 words out of the total 3300, which you can read at patreon.com/phen

Pinkie

Pinkie’s morning streams were always well attended. That’s when her balls were at their fattest and most enticing, filled to the brim from the brief nightly break in the otherwise non-stop orgasm that was her life. Given that the overactive cumfactories between her legs could produce lakes at the drop of a hat—and much, much more if she actually tried—seeing what extremes the vivacious pony might reach after hours of abstaining had become something of an Event.

“Good morning, Ponyville!” Pinkie said, her face filling the screen and transmitting her infectious smile across the airwaves. “Ready for another day of having fun, sex, and otherwise making a mess of the place?”

The lens struggled to capture all of her, even as she held the phone out for a wider shot. There was a lot of Pinkie to capture. Her cleavage, for one, didn’t seem to end; her breasts, as enormous as they were shapely, hung past her hips, dominating her torso entirely behind their marshmallowy curves. Then there were her thighs, plump and enticing, leading up to one of the most famous (and thicc’est!) rears in all of Hyperquestria. Both of these, Pinkie managed to overcome by switching to the front-facing camera and filming herself in the mirror; but no amount of trickery or enthusiasm could fully capture the enormity that hung between her legs: a dusky pink sheath so fat and massive that it almost touched the ground, wider than Pinkie herself and half as long.

“Uh uh! Houston, we have a problem!” Pinkie giggled, giving it a little wiggle. “Well. Let’s see what we can do about that.”

She moved her phone to and fro, trying a few more angles. If anything, she documented just how freely she moved despite what should have been a debilitating weight, between her legs and everywhere else. Her sheath propped up her boobs, and seemed ever so slightly larger every time the camera focused anew. Her balls, meanwhile, sat squarely on the floor behind her, so big that all the viewers could hope to see was a solid wall of pink scrotum. No green-screen for Pinkie Pie, she had her own! (And, once she really got going, had one for everyone else, too).

“Huh. Not really getting anywhere, are we?” she said, speaking over the gurgling noise emanating from her bloated cumtanks. “Why don’t you grab the camera, Pinkie?”

“Sure!” an identical voice chimed in, as the phone changed hands and, in case there was any doubt, a second Pinkie briefly stuck her face into view, gleefully greeting the audience, before going back to filming.

“Much better! Now we’ve got space to unleash the party cannon,” the first Pinkie said.

“There’s never enough space to unleash the party cannon.”

“So we’ll make space. Like always,” she said, grinning. “Who needs walls, anyway?”

It was not clear on the video feed if Pinkie was even inside at this point; her mirror had vanished and the only visible background was her ball sack; and given the little detail that could be made out, it looked too big to fit inside even a palace, anyway, several stories tall and still audibly bloating with every passing moment. Her sheath expanded in little, creaking bursts as well, though not near enough to keep up. Not until Pinkie laid both hands on it and started to knead.

“Ooh. Here we go,” she called out as the tip of her wide, pulsing pony penis pushed into view, slowly parting the delicate wrinkles of her sheath as it unspooled several feet of glistening girlcock. Then a few feet more. And more. And more…

“Yay! Let’s do it!” the other Pinkie cried, her own burgeoning erection invading the frame from below, too big to hide.

A third cock followed abruptly, from a hitherto off-screen Pinkie, giggling indulgently as she frotted her fattening fuckrod against the other two in frame. Three. Four. Five.

“Are you with me, Ponyville?” Pinkie called, laughing as she threw her phone back to another of her selves, pulling back to show the growing pile of identical ponies—or more accurately, the all-dominating parade of pink penises trying their hardest to cram together and only ending up growing faster from the pleasurable close contact.

“C’mon, let’s do it all together! Count down and cum, everyone! First orgasm of the day hitting in five, four, three, two…”

Rarity

“... One,” Rarity counted and let it go.

Well, in a sense. Rarity was always cumming, after all. But she could always go higher. Especially when she got swept up in the enthusiasm of Pinkie’s antics and let her big girl gush and grow as it pleased. Even a lady as classy as her had to indulge once in a while; she might as well give the rest of town something to look up to.

And look up they did. They had to. Because Rarity’s endowment literally placed her above the clouds, lying atop a lilac cock so monumentally oversized that it dwarfed a country by itself, to say nothing of her breasts, balls, and butt. There she lay, at the snug center of so many sexy curves, watching the show on her phone with a few essentials and snacks arrayed on a tray atop her vast acreage of boob.

She had been enjoying a slow morning, with tea and biscuits, casually feeding a dozen rivers from her cockhead many hundreds of miles away. Now, with a clench of her kegels and a tightening of her balls, the flow of cum became a raging flood, instantly overflowing everywhere at once as squirts of dickmare jizz sprayed across the landscape in violent surges and bombarded the sea.

“Ooh. That’s rather nice,” she murmured, watching Pinkie’s show with eyes half-closed as her body rewarded her with blissful intoxication for the loosened reigns. She hardly had to pleasure herself at all for her cock to throb and swell, taking advantage of Rarity’s lenient mood to add as many miles to its monumental bulk as it could.

But even if she didn’t have to, Rarity thought to herself with a little smile, there was no reason why she shouldn’t. And so her horn flared up with its magical glow, as a hand of telekinetic force wrapped gently around her kingdom-spanning cock.

“Ooh!” she repeated, more forcefully. “That’s really nice.” Behind and below her, her omni-virile balls churned and bloated, lifting her higher at a rapid pace, while far ahead of her—thousands of miles, now, rather than hundreds—the flow of her cum increased to such a maddening pace that the fluid level of the ocean rose visibly with each gush from her sky-kissing cockhead.

The telekinetic hands enveloped her breasts as well, dragging teasing fingers down the sides of her sensitive mounds, drawing little moans from the squirming dickmare as her bust, too, bwoomphed bigger, overflowing even the magically conjured palms cupping them. Titfucking herself was the easiest thing in the world—and although Rarity did not generally believe in taking the path of least resistance, she was not above putting her mountainous boobs to work. (‘Mountainous’ was, of course, technically a misnomer; Rarity’s nipples alone dwarfed the tallest elevation in Hyperquestria, and they grew harder and fatter at a frightening pace!)

And then, as her erection pierced the heavens and proceeded through the upper atmosphere, raining its thick, virile bounty across flooding world, a familiar voice spoke to her. “Having a nice workout?” It was Rainbow Dash, her voice booming through the thinning clouds.

Rarity jerked to attention, face flushed at being caught in her own fantasies. “Ah. Dashie. Well, dear, hardly a workout per se for a mare of my caliber, but you know, not entirely without merit…”

“I bet,” Dash’s voice continued, sounding eminently smug. Rarity was sure that, wherever she was watching from, she would be sporting a cocky smile. “Looks like you’re getting a little too hung for your magical tricks. Need a hand to tame the beast?”

“She’s most assuredly not a beast. My penis is entirely well behaved! She just gets somewhat… enthusiastic, at times.” Rarity glanced away for a moment. “But, I suppose I wouldn’t turn down a helping hand… to, you know, really hit the high notes.”

The clouds parted above Rarity, revealing not the sky, but a face, smirking down at her—as Rarity suspected—beyond the atmospheric haze. Rainbow Dash, at a titanic scale, like a goddess peering down at her creation.

“Say no more,” she said, and ran her world-altering fingertip down the length of Rarity’s twitching erection.
