Growing Up in a Flurry

“Here comes the train! Choo-choo!”

Sunburst, grand wizard of the Crystal Court, re-graduate of Princess Celestia’s School for Gifted Unicorns, and husband to the most powerful mage of the nation, whistled cheerily as he pushed the pea-laden spoon a few inches closer to the muzzle of his charge. “Eat up, little Flurry!”

“No!”

Sunburst’s smile twitched. “But it’s good for you!” He gave the spoon a little flourish. “Please?”

Flurry Heart pouted. “No!” She shook her head vigorously, then returned to sucking on her shaft.

Inwardly, Sunburst sighed. He’d known, to an extent, that this wasn’t going to be the most straightforward foalsitting job in the world. But even as he’d accepted Princess Cadance’s request, he hadn’t entirely realized what he’d been getting himself into.

Princess Flurry Heart was, in all respect, a strong, healthy foal. She was big for her age—a hearty three years—and had already started speaking the basic words that all foals soon grew to love. “Momma.” “Daddy.” “Hungry.” And, of course: “Now!”

Except little Flurry, it seemed, had added a most unfortunate word to her developing lexicon.

“Cock!” she shrieked. “Co-o-ock!”

Sunburst sighed again, but didn’t release his magic. The tip of his horn sparkled, and a bright orange glow twinkled around the girth of Flurry’s flare, all six inches of breadth pulsing steadily as they were pulled from the wailing toddler’s hooves.

“Flurry,” he said. He tried to sound stern—he really did. “You mustn’t do nothing but drink—ah, fluids all day. Your parents left me a specific list of meals for the weekend, and I am going to make sure that you eat a healthy, well-balanced—“

“Cu-u-um!” Flurry Heart’s hooves slammed against the side of her chair. The vibrations sent her mountainous shaft bobbing dangerously beside Sunburst’s shaft—a proximity that he quickly removed, noting with a tremble just how strong the filly’s musk was up close.

Sunburst chuckled nervously. Face flushing, he used one hoof to push his owlishly round glasses a half-inch up his nose. “N-no,” he said. He sniffed, and tried to draw himself up a little taller. He was the foalsitter! He had to be authoritative. “That is not part of a well-balanced diet. I’ve made you a perfectly good meal, and I expect you to eat it.”

Perhaps, a part of him hoped, the foal would listen to reason? To authority? To...something, anything other than the blasted beat of blood through that oversized sex organ?

He swallowed. Sunburst did his best to hide the trembling of his hooves as his eyes flicked back over to Flurry’s magnificent—massive tool. He’d scarcely been able to believe it himself, but he had heard it: her heartbeat, pounding, throbbing dully, not inches away from his cheek as a glob of arousal the diameter of his hoof rolled down its side…

A soft coo from Flurry struck him from his reverie. Blinking rapidly, Sunburst glanced down at his young charge—and blushed when he saw that the vibrations of the chair had caused the filly’s tremendous nuts to shake and slosh. Flurry moaned softly, both of her small hooves moving down to massage the great orbs as they seemed to swell slightly in size.

Egads. Sunburst’s cheeks felt hotter than the sun. What was this filly—so incredibly, dangerously virile that even the smallest acts were sexual in nature? How was this...normal?

He’d known, peripherally, of the family’s unique situation. Being the court wizard, though, he’d preferred to keep his distance from any personal affairs. Watching the little foal’s massive endowment sway gently from side to side, his muzzle twitching and nostrils flaring as a heady, masculine scent filtered into them, Sunburst realized that his distance may have been more of a gift than he’d ever thought before.

But he was a foalsitter, he thought. He had no duty sitting her and pontificating. He had a foal to feed, darn it!

“N-now—“ Sunburst cut off. Damnation—why was his voice shaking? Why was there a bead of sweat on his brow? He wiped it off, took a breath, and tried again. “Now,” he said, and was proud of the strength in his voice. “Like it or not, Princess Flurry, you must eat the dinner that has been prepared for you. It is the duty of royalty to be gracious, humble, and healthy, and therefore vitally important for you to clean your plate.”

Flurry didn’t even grace that with a reply; she just gurgled angrily. Sunburst’s cheeks puffed. His peas and potatoes were perfectly acceptable! Well, the peas might have been a bit soggy, and the potatoes overdone—but darn it, Starlight was the one who knew the cooking spells, not him! He’d done his best guesswork based on the instructions, but he’d be damned if fiddling around with stoves would ever be his forte.

And besides, a filly certainly shouldn’t have the pallate of a high-class Prench chef!

“Five bites,” Sunburst told her. He scooped a new pile of peas-and-potatoes up with the spoon and floated it in front of her mouth. “Just five bites! And delicious, too.” He slurped a pea off of the spoon himself, and swilled it around in his mouth, doing his best to produce a few sounds of culinary delight.

Flurry blinked owlishly at him. Her big, young eyes were wide, interested—almost contemplative. Happily, Sunburst swallowed and then grinned down at her. “See? Yummy!” He pushed the spoon a little closer to her mouth. “Now you!”

“No!” Flurry shrieked. Her horn suddenly blazed with a yellow-pink glow. Sunburst’s eyes widened—but instead of the worst, a similar aura merely sprang up around her tall, black mountain of a stallionhood. Flurry giggled as her magic pulled her shaft toward her, and then cooed appreciatively as she took it in both hooves. Her legs were still a bit too stubby to hold it completely in place, but with her magic helping too, she’d grown big and strong enough to wrap her little arms around nearly half of its tremendous girth. Rivulets of precum, thick and gooey, ran down her member’s length in streams. Flurry happily returned to lapping at the never-ending cascade of arousal, her meaty shaft chubbing up further beneath the ministrations of her tiny tongue.

Well then. Sunburst sighed. "Please?" he said, desperately. It sounded pathetic—he sounded pathetic, begging a foal a tenth his age to cease autofellatio long enough to actually eat her dinner!

(In a certain respect, he was somewhat jealous. He'd certainly never been big enough "downstairs" for his muzzle to comfortably reach his own—

Ahem.)

Biting his lip, Sunburst watched Flurry's suckling with a furrow to his brow. Really—this just couldn't be healthy, no matter which way it was spun. The source of Princess Flurry's apparently inexhaustible source of semen—his sheath twitched, but he did his best to ignore it—was still a mystery to the royal doctor, but no matter where her ocean-sized loads came from, there was no disputing the fact that it just could not have all of the nutrients necessary for a growing filly!

(Unless it did, a part of him murmured. His left thigh flexed at the thought's suggestive tone. Hasn't she grown so big? So strong? So virile? Surely a diet of royal cum might not be so harmful to one's health.)

Sunburst swallowed, and moved his gaze to the untouched plate. No. At the very least, Princess Flurry had to eat solid food at some point. He tried to picture her at a stately function as a mare, fifteen years older...and shivered as the image arrived with the equally firm illusion of a mountain of a penis sticking up from the slender princess' legs, towering over the rest of the party as literal rivers of precum overran the tablecloth and floor.

His groin throbbed—but Sunburst's hoof clenched against the carpet. No! He could not let that happen. He was a foalsitter, and he had been employed to care for the young Princess no matter the cost!

(But how thick that precum looks, the voice in the back of his mind said, slyly. How creamy. How gooey must it feel sliding down your throat. If such arousal is food for a growing alicorn, surely it must be nectar and ambrosia to an older unicorn.)

No.

Sunburst took a deep breath, and forced a smile onto his face. Surely there must be some way to...

His eyes latched onto Flurry's flare—or, more specifically, the valley cleft into the head of her shaft, just below where the gaping slit of her cock drooled precum down onto the floor and filly below.

His gaze switched back to the table, and to the peas waiting there. A ridiculous, desperate, obscene idea began to shape in the back of his mind.

Flurry Heart would only willingly ingest the produce of her...equipment. The way those fat gobs of arousal rolled down her shaft, however, gave Sunburst the beginnings of a plan. As he watched, the great pillar of meat shuddered, and then splurted out a heaping glob of precum. It drooled over the cleft in her flare, pooling there before running down the side—

—and slipping directly into the delighted Flurry's muzzle.

He couldn't have asked for a better delivery system if he'd designed it himself.

Carefully, Sunburst picked up a single green pea in his magic and levitated it toward the top of the beast before him. Flurry's member would have just barely reached past his eyes if fully erect, but in its semi-flaccid form, it flopped to the side just enough to give him the angle he needed.

As he moved, though, Sunburst couldn't help but shift in his seat—until his muzzle was mere inches away from the pulsing flare of the filly beside him. Flurry cooed softly, his little hooves pumping her magnificent meat...and Sunburst froze. Her musk was inescapable, indescribable, and incapacitating. He felt his nostrils twitch, his lungs expand...and his member plop out of its sheath, its girth thickening as Flurry's maleness caressed every inch of his body.

A flicker of magic curled his cape a tad closer around his body, but Sunburst could already feel his flaccid shaft stiffening toward an erection. Keep it clean, he told himself, floating the pea closer every second. You're a foalsitter—she's a child. Don't do anything you'll later regret.

But oh—he was hard now, and the throbbing in his cock was preternaturally strong. Sunburst swallowed as he leaned in further, angling for the perfect spot to leave his edible gift. His rear end pushed upward into the air, just slightly, but enough to let his unsculpted rump bounce and his tail flag upward. His thighs flexed, and he felt the weight of his testicles pressing heavily against them, each shifting muscle only teasing his erection further—

With a sigh, Sunburst released his gift over the target. Flurry didn't even notice—the weight of such a small pea was surely far too tiny for her mountain of malehood to take notice. Sure enough, as he sat watching with bated breath, her gigantic member twitched—throbbed—then glorped forth a fresh gush of precum. That high tide of arousal flooded into the cleft, swirled around the pea—and then lifted it up and over the side before depositing it directly into little Flurry's wide-open mouth.

Princess Flurry closed her lips. She looked briefly surprised, her cheeks puffing out. Then she chewed—chewed—and swallowed.

Sunburst could have cheered.

That was how the rest of the peas went, along with several of the potato chunks. One after another, Sunburst balanced them in the cleft of Flurry's great flare, waited for a fresh geyser of precum—and Princess Flurry swallowed the culinary reward with only the smallest squeaks of surprise.

Dinner was going swimmingly. More than half the plate was cleared, and Sunburst was more than ready to have his own meal. His throat was parched from a half-hour of cajoling and pleading, and he hadn't eaten since that morning, having been too preoccupied with last-minute paperwork to actually feed himself.

(But there's a delicious meal right in front of you. Princess Flurry would likely be gracious enough to share. Drink, dear Sunburst—guzzle from the spring before you; swallow the creamy delight of little Flurry's seed.)

Sunburst's shoulders tensed. His erection, halfway forgotten, throbbed forlornly between his legs.

Sunburst groaned aloud.

At the sound, Flurry paused in her precum-drinking. She blinked up at her foalsitter with big, blue eyes...and smiled.

Sunburst smiled back. It seemed the right thing to do. He'd read somewhere that foals responded well to signs of optimism, and—oh, darn it, she was suckling again.

Well, at least his methodology appeared to be working. Sunburst rolled his shoulders and stood a little straighter. They were in the home stretch. His mind ran over the checklist the parents had given him before setting out: Feed her dinner. Give her a bath. Tuck her into bed.

And then you're free.

(To jerk off in a lonely corner of the guest room while listening to the moans of that cute filly next door and fantasizing about her rutting you with that magnificent monster of a—)

In his mixed thoughts, Sunburst didn't quite pay attention to the chunk of potato he was picking up from the plate. This one hadn't been cut as small as the others, and in fact was large enough to make more than a mouthful for even him! Still, he didn't so much consider it as glance over it, still going over to-dos and to-don'ts in his mind while Flurry guzzled happily below him.

With a light splash, the chunk of potato landed right in the cleft of her flare. It didn't quite fit, and failed to nest comfortably in the valley of turgid flesh it had found itself in. Sunburst, though, paid little mind to that fact, instead turning to smile down at Flurry as thoughts of success ran through his brain.

Flurry Heart's tremendous cock twitched, flaring as it tensed for the inevitable geyser of pre. As the gigantic sex organ throbbed, its three-inch cockslit gaped wide open—and an errant twitch of the head pushed the potato chunk over the ridge of cockflesh to tip it right down the cavernous maw of Flurry's cock.

Flurry froze instantly. Not a coo or giggle escaped her. Then she hiccuped.

And she hiccuped again.

Sunburst had been waiting eagerly for the cascade of precum potato down into his charge's hungry mouth. When no such eruption was forthcoming, he blinked upward at the top of her shaft—he could have sworn he saw it throbbing—and then glanced back downward when he heard Flurry hiccup a third time.

What he saw made him pale. Flurry's cheeks were red and puffy, her eyes wide and confused. A few beads of sweat stood out on her little forehead, and her hooves were no longer wrapped tightly around her mammoth meat.

What in Equestria had—

Sunburst glanced back up to Flurry's girthy flare. Oh, no. Oh, no.

The ridge of cockflesh where he'd balanced the potato chunk was empty, the crevice dry. Sunburst's eyes widened, and he all but sprung forward. His stomach dropped when he saw that Flurry's cockslit was still gaping wide open, its fat lips trembling like a pony struggling to breathe.

"Oh, no," Sunburst groaned. He looked down at Flurry; the toddler's cheeks were puffed out fully, and she looked about to wail. "Oh, no. Oh, no—"

A quick illumination spell down her...urethra proved his suspicions correct. A thick white chunk of creamy potato was lodged about a third of the way down Flurry's monstrous member, its diameter stretching the passage until it could no longer progress any further down. The constant burbling of precum rolling down her shaft had ceased, leaving the little filly's stallionhood sticky, but swiftly drying.

Flurry hiccuped again. Alarm bells rang in Sunburst's head.

"D-don't worry!" he said quickly. Which of the two of them he was addressing, he wasn't sure. "It'll be fine. This is okay. I can fix this." Biting his lip, he leaned over the dark passage and tried a levitation spell.

The spell fizzled. Sunburst's ears wilted. "Drat," he muttered. "Alicorns are resistant to magic." It was impressive, really, just how much volume the cavern of Flurry's cockshaft held within it—but damn it, pontificating over the girth of her slit was not helping matters!

Sunburst's analytical mind shut off the part of him that had been eyeing Flurry fearfully—if not approvingly—for the past thirty minutes. There was a biological subject and an accompanying puzzle in front of him, and he had to solve it.

"Um," he said. "Maybe if I—no, that won't work." Holding his horn a bit closer to the gaping cockslit only made his spell fizzle faster; he could feel the magic evaporate the second he tried to fix his telekinetic grip against the slick walls of Flurry's urethral tunnel. It didn't help, either, that the filly's musk intensified with each inch closer his muzzle drew.

"The square-cube law," Sunburst muttered, somewhat fuzzily. Right. The strength of an aroma grew in proportion with the ratio of -

Flurry's cock throbbed—and then shuddered to a halt. Beneath him, Flurry let out a tiny, burbling cry.

"S-stuck," she moaned. "F-full."

"It's okay," Sunburst mumbled. "We can fix this." Something groaned, creaked. Sunburst's eyes widened as he felt something warm, plump, and heavy push against his leg. Glancing down, he saw one of Flurry's hoofball-sized testicles pressing uncomfortably weightily against the inside of his thigh. Even as he watched, eyes wide in awe, the great black orbs glorped, sloshed, and swelled imperceptibly larger.

Flurry's eyes were watering. "F-full," she whimpered. One of her little hooves pounded weakly against the side of her broad shaft. The monstrous organ shuddered, but not a drop of liquid escaped her gaping slit.

Frick, frick, frick. Sunburst stared anxiously down the dark passageway of Flurry's cockslit, forehooves prodding together as he balanced just above it. No, no, no. This was not going well. There had to be some way to get the chunk out.

Flurry moaned again. "C-cock," she mumbled. Her little hooves pounded together this time, and the entire pillar of meat shuddered with ominous tension. Sunburst could feel the mass of spooge in her mighty balls churning heavier by the second as they pushed harder against his thighs, overflowing the seat as they dropped toward the floor.

"It's okay, it's okay, it's okay." Maybe repeating it would change things. Sunburst gulped. His own erection was pulsing in time with the rhythm of Flurry's, a tiny candle flashing to the beat of a towering titan of a lighthouse. His little balls felt heavy and tight, despite all of the size those monstrous cum-sacks had on them.

Flurry's eyes teared up further. "C-c-cum," she wailed. "Cu-u-um!" She pounded on her shaft, again and again, confused, helpless, and thoroughly unable to achieve release.

Sunburst's mind was short-circuiting. Magic was out of the question. Flurry was not happy, and the situation was getting more unmanageable by the minute. How was he supposed to—

A muscle in his thigh flexed—and the sheer weight of Flurry's nuts suddenly seemed to redouble. Sunburst gasped as he lost his balance. He tumbled forward, hooves reaching out to catch his fall with the first hoof-hold available—

Squelch.

Time seemed to stop.

His right hoof had caught his fall the only way it could: by sinking into Flurry's turgid rod up to the foreleg.

Sunburst's eyes opened wide. His cheeks flushed crimson. His erection throbbed.

Flurry had stopped wailing. She didn't even hiccup. She just stared at him, wide-eyed and dumbfounded.

Sunburst would have felt much the same himself if he didn't feel close to sobbing. He'd known that her stallionhood was squishy, and seen how wide her slit was—but even so, this didn't quite feel real. His foreleg tensed, and little Flurry gasped. The slick, pre-drenched walls of her member flexed around his hoof, their rapidly drying walls clenching almost hungrily.

Oh, no. Sunburst nearly yanked his hoof out immediately—but then felt something cool and lumpy brush up against the back. His cheeks reddened, and he glanced back down at Flurry. She hadn't made a single sound; her little back was perfectly straight against her chair, with her big eyes wide and unblinking.

Sunburst tried to put a smile on his face. A crooked, twitching grin kind of touched his lips, but altogether it just looked somewhat sickly, especially given the deep blush that slashed across his muzzle. "J-just a moment," he croaked. "I'll have it out in a jiffy. Just..."

He wriggled his hoof a bit further down Flurry's shaft. The filly gasped as his hoof twisted against the walls of her urethral tunnel, his wrist's fur whispering against her walls as jellied globs of precum matted his coat. Sunburst squeezed his eyes shut, doing his best to ignore the mountain looming before him even as Princess Flurry's musk invaded his lungs with every breath.

He just had to push a little further. A little harder. He was almost elbow-deep into her cock now, her slit gaping hungrily around his foreleg with each inch forward he pushed. His hoof wiggled—Flurry gasped, and then moaned softly. A bead of sweat stood out on Sunburst's forehead, and he decided that he very much did not want to decide how this felt.

Flurry's nuts were enormous now; reaching halfway down to the floor, they were easily wider than his torso, with a musk so thick it was intoxicating. Sunburst's thoughts swam warmly, for all that he tried to keep himself on task. The potato chunk was almost in his grip now—he just had to lean a bit further forward. Sunburst chewed on his tongue and rocked his weight forward. His hooves went on tip-toe, and a bead of sweat dripped down his cheek. Almost...there!

He grabbed the potato chunk in the cleft of his hoof, twisted it—and Flurry's testicles gurgled.

The seed that had building up with each moment of stoppage had let her great nuts roil and churn, swelling up with restrained, unreleased pressure, suddenly found a path of least resistance to travel through. The chunk that had blocked it off had suddenly been tweaked—just enough, at least, to let the pressure force its way upwards.

And force its way it did. Sunburst had barely enough time to register the deep, ominous rumbling in Flurry's ballsack before a geyser of arousal blasted up against the force of gravity. The gush of backed-up pre flooded forth like the breaking of a dam; Sunburst's hoof was thrown wildly free just before a torrent of real spunk blasted him across the face.

He stumbled back, sputtering, blinded by the thick, gooey wad of cum that had splattered across his face. He fell, smacked onto the floor, and moaned as thick precum drooled across the fur of his foreleg.

Something was in his mouth. It was lumpy, hot, and coated with something thick and gooey. Sunburst tried to breathe—couldn't. His nostrils were clogged with something that made his crotch ache, and his rump flex. Trembling, shaking, he chewed on the object in his mouth—and moaned quietly. Thick, goopy cum flooded down to fill his belly as he swallowed bite after bite of the potato chunk that had caused so much trouble. Infused—no, enshrined—with Flurry's seed, it was the most delicious thing he had ever tasted.

And then, with the world still swirling from the fall, the world—only briefly—blinked out.

When Sunburst came to, the first thing he heard was Flurry's soft moans. They didn't sound pained—they sounded...grateful?

The kitchen came back into view. Blearily, Sunburst sat back up...and saw Flurry hugging her shaft once more, gently lapping at the great globs of spunk still rolling down the sides.

The devastation was incredible. The table was covered entirely with a watering hole of precum, and a wad of spunk larger than Sunburst's head had splattered across the ceiling above them. Droplets of jelly-like cum, cream-colored and thick, dripped down onto the floor like fat raindrops, forming puddles and rivers wherever they fell. In the middle of it all sat Flurry, little hooves massaging her great shaft as she cooed and giggled.

With a grunt, Sunburst heaved himself to his hooves. It was only with a small amount of wobbling that he made his way back over to the table. Once there, he first spared a glum look for the dinner he'd so lovingly prepared. The remaining peas and potatoes were all covered with a layer of jizz so thick it'd be a miracle to wash it off the plate, let alone the food.

Flurry looked up at him and beamed. "Cum!" she chirped.

Yes. Sunburst stared down at her...and then couldn't help but chuckle. There was no point in trying not to—the situation was just far too ridiculous.

"Yes," he finally mumbled. "Cum." Flurry grinned, and then stretched her hooves upward.

It took him a moment to realize what she was trying to do. "Oh, no," Sunburst said. He reached to move her hoof away. "We are not putting anything in there again."

Insistently, Flurry began to tug his hoof up toward her fat flare. "Cock!" she said brightly.

Sunburst's cheeks flared. "Oh, no." Nope, nope, nope. "You want me to put my—oh, no." Flurry's shoulders slumped, and Sunburst couldn't help but feel a twinge of shame.

Finally, though, he managed to clear his throat. "Well, then," he said, deliberately. "Shall we get you—erm, cleaned off, then?"

Flurry just wriggled her little legs delightedly. She had somehow, he noticed, with more than a twinge of shock and envy, managed to escape the eruption without more than a single rope of her own spunk decorating a strand of her mane.

The next step after dinner was bathtime. It was, surprisingly, uneventful. Sunburst did his best to mop off the bulk of the cum from the both of them, using magic where he could and using his hooves when a bit more elbow grease was required. By the end of it, the drain was clogged with long, ropey strands of goopy spunk, and the bathwater better resembled yogurt than water—but Flurry, if not sparkling, was at least clean and happy.

Thankfully, the next step on his foalsitter’s to-do list was also the last one. If he were being honest with himself, Sunburst had been looking to bedtime for the better part of the past ninety minutes. The three-year-old princess was a hoof-full at her best, but the events of dinner had left him thoroughly exhausted. That didn’t even touch upon the stiff, steadily throbbing horsecock that had prodded stiffly against his belly with each movement he made. Sunburst may have been red-faced and stammering, but one part of him was thoroughly enjoying the experience.

Tucking Flurry into bed was easy enough. Unlike most foals her age, she had no complex night-time rituals—save for one.

“Good night, Flurry,” Sunburst murmured. He tugged the thick quilt up over her; the foal yawned, and snuggled up to her sheets.

Next… His glance drifted over to the large, black mass sitting silently beside her. He couldn’t help but follow the curve of it, the bulge of its girth beneath the covers—down, and down, and down, all the way to the great, twin mounds right over Flurry’s little crotch. Sunburst swallowed.

But it had been on the to-do list. And—oh, who was he kidding? He wanted to, anyway.

Muzzle shaking slightly, Sunburst leaned forward, puckered his lips—and planted a kiss right on the tip of Flurry’s monumental stallionhood. The filly cooed, then moaned softly. Cheeks burning, Sunburst swiftly withdrew, though not before noting the long, dark stripe of wetness running down Flurry’s pillow. It began at the great, looming shadow of her flare, and pooled in a rippling puddle depressed beneath the crook of her elbow.

Sunburst hesitated again, and then quickly ducked down to kiss Flurry’s forehead. “Good night, Flurry,” he said again. He added, mumbling this time: “Good night, Big Flurry.”

Dammit—it had been on the list!

Flurry yawned, and then smiled as her eyes drifted closed. “Night-night,” she mumbled.

Sunburst smiled softly, and withdrew to his own room.

It had been generous of Cadance and Shining to set him up in the guest room of the Royal Quarters themselves. He would have been fine on a ratty old couch (to an academic, ratty couches were the most tasteful of furniture, only behind lumpy armchairs), but it would have been a struggle to find anything in the Royal Suite that was anything less than perfect. His guest room especially was…

Well. A good part of his home could have fit into it.

Flopping back into a bed wide enough to accommodate a family of twelve, Sunburst was greeted with the sight of his stallionhood slapping happily against his belly. It left behind a strand of precum stuck to his stomach fluff. Blushing, he slid a hoof down his side and gave his thigh a squeeze. Every sensation felt...stronger. Intensified.

Sunburst exhaled. He was trembling, he realized—just his hoof, admittedly, but it felt like small earthquakes were going off across his body. He’d never been supremely well-endowed downstairs, but if he’d taken a measurement right now, he’d be willing to bet that his cock was harder, and perhaps then longer and thicker than it’d ever been.

If only slightly.

Slightly. Oh, gods. It wouldn’t matter if his shaft had doubled in length, wouldn’t it? Not next to that monster. Eight inches was respectable for a male of his stature (though he’d caught sight of the fourteen-inch tower swaying and smacking between Shining’s legs on more than once instance), but beside Flurry’s thirty-six? And growing?

He’d always been enough for Starlight. Or at least, he thought. But Flurry…

Sunburst’s lower lip wobbled, and he let his eyes slide shut as the image of his marefriend touched his thoughts. Oh, frick. Starlight.

They weren’t married yet—weren’t even engaged. Two years of going steady had left a certain feeling of reliance in the bedroom, though. She was his, and he was…

...hers.

Sunburst’s hoof touched one of his swollen testicles. He cringed at the sensitivity of it, but groaned aloud as his cock pulsed against his belly.

He’d never really been much of a precum producer—his balls had never really been that productive, he supposed. But now, here, a veritable river of the stuff was running down between his legs. Sunburst remembered the cascade of liquid lust flowing down Flurry’s shaft, though, and shuddered.

He loved Starlight. With all his heart. But Flurry—she was just so intense. There was just...so much of her. It made his body arch, made his tail flag, made his rump sway as he walked her back to her bedroom…

Sunburst’s eyes shut tighter. A quiet whimper escaped his muzzle. Gods, she was a foal. And he was—he—

—couldn’t help himself.

A smile, crinkled and trembling, slipped onto his face. One hoof wrapped around his drooling shaft, and the other moved to massage his aching balls. It was all too easy to imagine the taut surfaces of his charge’s massive, cum-filled orbs supporting his own, just as it was easy to imagine the weight of her three-foot cock rising up before him, pinning his pathetic little member against his chest.

Sunburst’s breathing was growing shorter. Faster. More erratic. His cheeks burned, and droplets of sweat stood out on his forehead. More precum poured from his erection onto his chest.

Starlight would understand. She had to understand. Schlick-schlick went his hoof. Pant-pant went his tongue. Flurry was—Flurry was too much for him. She was too much stallion for his imagination, his libido, his fantasies to ignore.

And at least, he reassured himself, sucking in a breath as his balls contracted against his groin, he wasn’t actually doing anything worse than masturbating alone -

“Mister Sunny?”

"Wh-wh-whoa!"

Oof.

Sunburst moaned pathetically from his place on the floor. He'd been sitting on the edge—both sexually and physically—and so when Flurry's chirping voice had rang out just inches away, he'd spilled, flailing, over the side of the bed. He'd taken a belly-flop onto the carpet, and now lay, glasses askew, with his legs splayed awkwardly around him.

His eyes fluttered open. Sunburst moaned again, this time more from the stimulus of the raspy carpet against his erection. He'd been so close!

But Flurry—

His eyes shot wide open. Flurry!

"Oh! Princess Flurry!" Sunburst was on his hooves in an instant. Blushing, he kept his eyes downcast, and angled his hind legs to try and conceal his throbbing boner. "Is something the matter? I thought I..."

His gaze flickered upward...only to find a massive, throbbing pillar of meat sticking out two feet in front of Flurry's forelegs. A river of precum as wide as his hoof drooled from the slit, pooling over and staining the carpet. Little Flurry looked up at him with wide eyes, her stubby toddler's legs stretched awkwardly around her own girth.

Sunburst sighed. He straightened his hind legs and relaxed his haunches. His boner, free once more, sprang out and smacked against his belly. "...tucked you in."

Flurry pouted. "Can't sleep."

"Oh," Sunburst said. "But you had a long day! Maybe you can just go back to"—his mind scrambled, searching for suitably paternal language to use—"your nice, big-girl bed and close your eyes, and—"

"No!" Flurry shrieked. “No sleep!”

"U-um." His voice was shaking; why was it shaking? Sunburst tried to keep a straight face, and glanced down at the hopeful-looking filly. “What—what helps you fall asleep?”

"Fuck!" she chirped.

He could've whistled aloud. Hoooh, boy.

His boner leapt at the thought. Someone really liked that idea. A vision struck him: Meek little Sunburst, rump wriggling up in the air, waiting as the musk of a proper stallion suffocated him, balls the size of melons slapping against his jiggling ass—

"Right," he blurted. "That is—perhaps...not?" Flurry looked confused. Scrambling, Sunburst searched for a way out. He didn't trust himself to...help, no matter how clinical the need might be. His boner kept throbbing, and he found his nostril flaring a little bit wider, his breath inhaling a little bit stronger. Flurry had scarcely been in the room for ninety seconds, and already her musk lay over the air like a dense, heavy soup. His balls pulsed; his flanks clenched.

But Princess Cadance—

No, he told himself. That was Princess Cadance. He was—he was Sunburst. Archmage Sunburst. Coltfriend to—to—

—what was her name again?

That musk was so thick. So heavy. It was just so hard to think...especially when every throb of his own cock drew him to the incredible swell of Flurry Heart's nutsack, even as her testicles steadily bulged larger by the second.

Archmage Sunburst gulped.

And then an idea came to him.

"Well," he said. He drew in a shuddering breath. A smile plastered onto his face, he met Flurry's eyes and went on, "I don't know if I should—do that, but I can help you fall asleep."

Flurry Heart cocked her head to the side. A particularly powerful flex of her cock sent a glob of precum the size of a saucer splatting rudely against one of his bedposts.

Sunburst winced.

"Storytime!" he said. "I—they always helped make me sleepy. When I was a colt," he added, grinning awkwardly.

Flurry gasped. "Story!" she chirped. Her hooves thumped atop her great organ in thunderous applause. Each impact sent another glob of precum shooting across the floor until the outline of a small country was painted in liquid arousal upon the carpet. "Story! Story!"

Sunburst had to chuckle at that. "Okay, then—storytime it is." He heaved himself up onto the bed, then patted the mattress beside him. "Up you get, little Flurry."

The three-year-old suddenly looked very focused. She trotted over. Sunburst couldn't help it as his gaze drifted to the way her megacock rasped on the carpet as she dragged it along, or the way her tiny body heaved her massive, sloshing nuts across the bedroom floor.

Grunting, Flurry reached both hooves up the side of the bed and heaved. Her hooves tightened around the sheets, crinkling them as her little wings buzzed—somewhat uselessly. Flurry panted, whimpering as she did her best to pull herself up with every ounce of her power-packed little form.

Below her, a pair of testicles, each larger than her entire body, kept her anchored to the floor.

"Here," Sunburst said, horn lighting without thinking. "Let me help." Sparks shimmered around his horn, and Flurry gasped as he picked her up in his magic.

A tremor went down Sunburst's back as he laid her down. There was a certain tactile feedback to telekinesis, but he'd never paid much attention to it before. Now, though...

He'd touched Flurry's...thing, back at dinner. He'd felt awkward about it then, and had tried to disengage as quickly as possible. But now, cradling her erect, three-foot python in one weave and hefting her twenty-pound semen stores in another...

Sunburst's cheeks flushed. Gods, but those things were heavy.

Flurry sighed contentedly as she touched down. The mattress shook, and then—as Sunburst's magic disappeared—depressed beneath the weight of her mighty stallionhood. Sunburst exhaled.

"Okay," he mumbled. He shifted back, and got comfy against a few extra-fluffy pillows. Flurry watched, and then emulated him. It took her a bit more effort—especially given the added weight at her crotch—but the toddler filly managed to wriggle herself back until she was laying back against the pillow beside him.

"Okay," Sunburst said again. He took a breath—and then blushed. "Urk." Flurry had snuggled up to his side. Her little cheek rested upon his belly—and her great, throbbing stallionhood was draped almost tenderly across his legs.

"Story," she chirped softly.

"Story," he echoed. "Story..."

The filly expects a story, Sunburst told himself. So it's up to you to deliver.

But it was so terribly hard to concentrate with that massive meat weighing upon his knees...

Sunburst gulped. Welp, there was nothing doing for that. He had to shoulder the weight and push on. An archmage didn't give up. Right?

Right?

"There...once was a princess," he finally said. "She lived in a big castle."

"Me!" Flurry cooed.

"A very big castle," he mumbled. "And like you. She, ah—loved to run! And jump, and play. Very much like you."

Flurry's wings buzzed appreciatively. She cuddled up closer to Sunburst's side. Sunburst's mind was adrift in the world of storytelling...but his eyes were fixed closely on the mammoth black shaft that was steadily stiffening with each heartbeat.

"She, er, wielded a great weapon! Fought many battles." Battles? What the heck was he—

"And it was called her Wand of Power."

Flurry oohed and aahed. Sunburst could have smacked himself.

But it seemed to be working. He could feel her heartbeat slowing against his hide. Letting himself smile a bit, Sunburst went on.

He talked about the adventures the princess had—her and her Wand of Power. He talked of the monsters she conquered, the friends she made, the strange creatures she met. Flurry giggled at the right parts, and gasped at the other. She seemed to be thoroughly enjoying herself.

And so, Sunburst discovered, was he. He was falling into a rhythm, a beat—and who cared if that beat seemed to be in time with the throb of the beast drooling arousal over his thigh, or that Flurry's little hoof seemed to be not-so-innocently stroking circles around his flank?

He was a mage. And there were stories to be told.

By now, Flurry's cock had chubbed up even further. It had to be as wide as his torso, easily, and a bit longer besides. Its further stiffness had pushed it up past his navel, with the tip coming to rest just a few inches beyond his ear. Sunburst drew in a deep breath of its musk, and groaned softly. Absentmindedly, he picked up a hoof and drew it in a long, casual stroke along its length. Flurry cooed beside him, and he heard himself grunt alongside her. Her mighty shaft was draped completely over his lap, and his own erection—his own tiny eight-incher—was squeezed beneath a small cross-section of her thirty-six-inch python, each throb of Flurry's pre-soaked member masturbating his little boner as he clenched and groaned.

But all good stories have to come to an end, eventually. "And so," Sunburst finished, yawning, "she returned home and lived happily ever after."

Flurry yawned with him. "Happy."

"Yes," he said. Smiling warmly, he turned to give her curls a pat. "Happy."

It was time, he decided, for bed. He glanced at the clock: Eight-o-six. Not bad. Now, if only he could get her back to her room...

Shifting his weight slightly, he hefted her just far enough from his side to let his magic get a good grip on her—and her additional weight. Sunburst's bleary eyes twitched as he felt the mass fill out his telekinetic grip. Goodness, but he didn't remember her being that heavy.

Flurry whimpered.

"Come on, little Flurry," he mumbled. "Time for bed. Time to get up."

"No," she whimpered. "Can't."

He paused, then stared at her blankly. "Can't? Why not?"

Her big eyes were wide, her lips tight. "Full."

Sunburst blinked. Then, craning his neck to the side, he peered around Flurry's little flank...to see an enormous jet-black sphere as tall as his shoulder weighing on the ground behind her.

His eyes bulged. "But—how—"

Another quick glance confirmed that her second testicle was as insanely large as the first. Sunburst swallowed. His own balls were around a third the width of his hoof—not large, but not small, either. At dinner, Flurry's had been around the diameter of dinner plates. But now?

He shivered. He could see them pulsing—breathing—from here. How in the blazes had he not noticed their growth?

"Um," he said, in a very small voice. "Er. Yes. Very big."

"Mommy helps," Flurry added, helpfully.

Sunburst attempted to register that. "Sorry?"

"Mommy helps," Flurry repeated. She nodded over at the pile of papers detailing her care; he'd rested them on his night-table after bathtime. "Says so."

Sunburst frowned. He turned to shuffle through the pile of notes Cadance had left for him—and then noticed one sticking out from below the night-table.

It had a ridiculously long section dictating the kinds of carrots Cadance had picked out for snacks, and then:

Please ensure that Flurry is released once every thirty minutes. I know that it might be an awkward, as well as messy task, but it's important to make sure that she doesn't get backed up. Two sessions before bed will finish her off for the day—her body's clock ends at seven P.M. sharp. A cleanup containment spell might come in handy!

There were a few other scribbled notes after that, but Sunburst didn't bother to read them. He didn't need to.

Slowly, he turned back toward Flurry, who was staring up at him with a pained look. Once every thirty minutes. And twice before bed.

He glanced at the clock. It was now eight-oh-nine. Over an hour since she should have been "released" for the final time.

Twice.

Crap.

He swallowed. “So...your mother usually helps. How?”

Flurry pondered that for a second. Then: “Night-night kiss!”

A...kiss. Sunburst eyed the gaping, precum-drooling slit of her member and licked his lips. Right. “Does...your father do anything different? Perhaps he also helps?”

Flurry didn’t even have to think. “Daddy fuck!”

“Flurry!” Sunburst’s breath caught in his chest. “You mustn’t say that!”

She didn’t seem to care. “Daddy fuck!” she giggled. “Daddy fuck! Daddy fuck! Daddy—Daddy cu-u-u-uum.”

Her eyes rolled back a bit; her tongue lolled out of her mouth in indisputable arousal. Her cock bulged, flexed—and then spat a wad of precum half the size of his head across the room. Sunburst flinched as it splattered across the glass balcony doors, and watched in awe as the thick, gelatinous mass slowly oozed down to the floor below.

Her balls, tremendous in size and only growing, gurgled, then visibly expanded. Sunburst swallowed as he watched little Flurry's nutsack roll over the quilts of his mattress. Her massive nuts, each twice the size of his head, gurgled audibly with each inch—then each foot—of mattress-space that they swallowed up. Princess Flurry Heart, and her massive cock flexed. Trembling with barely bridled virility, the powerful organ slowly lifted into the air, inch by inch, until it was standing tall and proud like a flagpole. Its bulk cast the bed into darkness beneath its shadow; leaning back on his pillows, Sunburst felt his mouth go dry, his muzzle trembling with awe as he felt its musk and sheer size dominate his senses utterly.

"O-okay," he stammered. "Just—just let me—let me take a look." He slid off of the bed, and thumped onto the carpet. Hesitantly, he padded his way around the corner of the mattress. His tail was curled tightly over his taint, concealing his shiny balls, already moist with the precum that had slid down his own throbbing length.

And then, without warning, Flurry's nuts loomed in his vision, filling it utterly. Sunburst licked his lips, then groaned audibly. His legs shook—his tail flagged, eager ponut clenching—as those great spheres sloshed, then groaned as they rolled out to cover another inch of area.

They were nearly to the edge of the mattress.

"O-okay," Sunburst mumbled. He took a deep breath—and then halfway regretted it when he found himself choking on the little filly's powerful, invasive musk. Clearing his throat, he moved to straighten his spectacles, then leaned in even closer.

Her scent was overpowering, but somehow, he held onto his will as he bent forward. Swallowing, Sunburst inspected Flurry's nutsack—every curve of her gigantic, cum-swollen orbs, every nook and cranny of her overstretched, overstuffed ballsack. His cock throbbed in time with hers, and his tail leaped with an eagerness to please—to taste—to submit—with each fat dollop of precum that rolled down the little filly's cock.

He was swaying himself, he realized. Bobbing, his eyes half-lidded, entranced by the massive organ before him. Taking a deep breath—and savoring the impeccably maleness of her scent—Sunburst lifted up a hoof...and laid it atop one of Flurry's swollen orbs.

He put some weight on it. The testicle resisted: taut, firm. He rocked the weight to one side, and whimpered quietly as he felt its contents slosh beneath his touch. There was just so much...

"It's okay, Princess Flurry," he mumbled. His voice was almost a whisper now. "We'll take care of it."

His hoof moved to push around her nut in small circles. Their radii slowly grew, his hoof pressing more firmly into the taut skin of her ballsack with each lap. Flurry's soft voice cooed in approval.

The hypnosis—for what else could he call it?—intensified. Sunburst felt compelled to bend in further, to lean in close—until his horn was very nearly rubbing against her cock. He tilted his head forward, and then moaned aloud at the sensation as his hard, sparking horn pressed into the firm flesh of Flurry's rod. She was so...hot. Burning, even. He felt his cheeks rise in temperature, felt sweat dripping down his shoulders and back, and found that he didn't care one whit.

He was a foalsitter. And he was going to do his job.

Sunburst's lips parted. As if it were as natural as breathing, he extended his tongue and then licked along the top of one testicle. The rough surface of his tongue dragged across the taut, swollen orb, the skin of Flurry's nutsack piling up with his movements. Flurry's little gasps were music to his ears, and Sunburst did it again—and again.

Each lap of her ball tasted even better than the last. Her musk—her taste—her scent was stifling, invigorating, dominating. Sunburst's barely-chubby rump tensed and swayed, his tail flagging as he moved to suckle on Flurry's great nuts.

Precum continued to drool from Flurry's flare. A fat dollop oozed down his cheek, then another found itself stuck in his mane. Sunburst just brushed any hair out of his eyes; he couldn't have any obstacles separating him from his prize.

Was it his prize? Or his god? He moaned, hips pumping, as he buried his muzzle deeper in the cleavage between her testicles. Flurry's satisfied moans and whimpers egged him on, pushed him to nuzzle deeper as the weight of her massive nuts pressed against either of his cheeks. He took the bridge of her nutsack in his teeth, delicately, and rolled it against his tongue as his lips suckled harder on the skin there.

"O-oh," Flurry gasped. "Oh—oh—ooh."

His tongue emerged again. Tenderly, lovingly, Sunburst lapped his way up between her pre-drenched nuts, making sure to taste the pool of precum at the base of her shaft. Then he went higher, drawing his tongue up her shaft and twisting it around each vein with tender care, letting each one fill his mouth as Flurry cooed and sighed. He sighed, too, his shoulders relaxing and his crotch throbbing as he reached the base of her medial ring and lingered—only for a moment—before removing his tongue completely.

Then:

"Daddy fuck?" Flurry mumbled.

Sunburst's cheeks burned, but he offered his charge a gentle, eager smile. "Not daddy," he corrected her. "But...yes. Fuck.

Flurry applauded—and then moaned when his hooves, digging into the mattress to heave his weight back up—pressed firmly against the exposed flesh of her nutsack. Sunburst grunted, and then exhaled when he flopped back onto the bed. His cock throbbed, and he spared a moment to pump his hips and erection against the quilt, the soft, pre-drenched fabric lovingly caressing his mast.

"Y-you know, Flurry," Sunburst said. He drew himself to his haunches, and stroked Flurry's engorged erection with a hoof. The little filly moaned; Sunburst smiled. "There's m-more to the story I told you."

"Mmmmm."

"The princess had a"—Sunburst stumbled—"a—a servant." He stood up; each of his hooves sank a half-inch into the well-padded quilts. His erection was throbbing, drooling; his balls felt like lead weights. His tail was all but curled over his back, exposing his rump completely.

"She was"—he gently pulled Flurry's cock downward, just low enough to have an angle—"a lovely, pretty servant. She loved to—um, play, and tell stories. And she"—a shiver went down his spine—"loved the princess' wand of power."

His taint was rubbing against the side of her shaft now. Precum, cupfuls of it, gushed down over his bare ass, underused archmage muscles flexing and shifting delightedly with each throb of the mammoth mountain against his ring. Sunburst bit his lip, then gasped, as Flurry's nuts gurgled and rolled further forward across the quilt.

His thighs spread—wide, then wider still. "Sh-she loved it," he went on, then stifled a moan. He could...feel her now, the great curve of her flare pressing against his hole. Oh, gods, but she was big. So big—so powerful. Had he ever been a male? Could he ever be a stallion again, especially in the presence of this...thing?

This filly?

"She loved it so much," he panted, "the she would...clean it." Flurry's cock pulsed, and Sunburst groaned. His tight ring had unclenched just a bit—and the volley of precum that Flurry sent forth had gushed right down through. He could feel it already sloshing in his belly, and each throb of the foal's organ only brought more. "She would...kiss it." The vision of those nuts—those tremendous, beautiful nuts, sloshing and groaning with gallons upon gallons of fresh, hot, virile seed—filled his mind's eye. "Even w-welcome it inside of herself."

Flurry was moaning. Even as he sweated, even as he panted, groaned, and held his weight up, Sunburst felt warmth rise up inside of him. Good.

He shifted the weight, pressed downward. His horn flickered with a spell—trembling, his little ring suddenly unclenched, the shimmer of magic relaxing it. Sunburst exhaled, then pressed further. He was pushing it in. He was doing it. He was—

With a pop, her cock went in. Sunburst's eyes bulged. He nearly howled—but instead only moaned, his voice pitching up like a filly a quarter his age. Trembling, shaking, but with erection throbbing and balls churning, he pressed onward.

"The p-princess," he breathed, "and her—her s-servant... They liked to play." A little bit more. Just two inches. Good. Breathe. Two inches more. "The s-servant...would tease her princess. Whenever they were alone." He sucked in a breath—and then pressed further. A full six inches—half a foot—of girthy, Flurry meat were now buried in his ass.

Further still. A foot. Sixteen inches. He could feel her in his belly—his hoof flew to his gut, feeling the mound swelling there. He could feel her. Gods.

Now he could feel it—the fat girth of her medial ring. It was firm, an inch wider in radius than the shaft, and absolutely throbbing with heat. Sunburst gulped—and then shoved his weight downward.

He wailed, head jerking back as his ruined asshole gaped around Flurry's mass. He was full—oh so full—but there was more, more, so much more—!

"Th-the princess would ask," Sunburst groaned, "wh-why, it looks like you're very nearly pregnant?" He wriggled his hips, pushing to fit a few more inches inside of him. The bulge in his belly swelled; by now, the fat curve of Flurry's flare could be easily seen in the outline of his hide. He did look pregnant, big and round and full of precum. More and more of Flurry's liquid arousal gushed into him by the second; he rocked his weight backward, and felt his belly slosh against his thigh. Sunburst whimpered.

And then, he started pumping his hips up and down.

"The—the w-wand," he panted, "felt so—sweet inside of her." His puckered, ruined ring clenched, and little Flurry moaned. Her balls groaned, their contents gurgling as they pushed up around Sunburst's hooves. His next descent brought him all the way to the bottom—Sunburst gasped, feeling her cock bulge out his belly grotesquely—and he groaned as his plush rump sank into the taut, cum-swollen surfaces of Flurry's massive seed-sacks.

"It felt so warm," he breathed. "She—she wanted to keep it there." His cock throbbed against his belly—then, as he went down again, against the massive bulge swelling in his belly. A fresh jet of precum widened his belly further—making room, it seemed, for the inevitable eruption. He swallowed.

"She wanted the wand's hot, g-gooey magic inside of her," Sunburst grunted. "She wanted to feel it—feel it f-filling her up." He sank all the way down again, and whimpered as his tush pressed against Flurry's nuts again. Were they even bigger? How much—

"She wanted t-to feel it stretch—stretching her out," Sunburst mumbled. His hips wriggled happily, his gaping ponut struggling to suck in each inch of Flurry's cock it could. "The servant wanted to show that she was marked—that she was fertile—that she was own—own—oh!"

His hips jerked forward, his cock flexed, and he came. Sunburst squealed like a pig in heat, jerking, humping the air as rope after rope of seed spat from his pulsing tip. His whole body shuddered with the force of it, the roar of climax filling his ears as he panted, wailed, and came like he'd never cum before.

He could feel Flurry's head buried deep in his belly; each twist of his hips sent his spasming cock slapping wetly against the great bulge in his gut. Sunburst moaned like the sluttiest showmare, as high-pitched as the youngest filly—and still, he came. His thighs flexed, his forelegs thrashed, and his hooves tensed...right around Flurry's great, plump nuts.

He heard her before he felt it—a stifled, moaning gasp of surprise. That surprise came with pleasure—tension—and then, at long last, a filly's gentle sigh of release.

A massive rush of spunk flooded inside of him; in an instant, his ruined asshole was forced near twice as wide as Flurry's cock bulged with gallons of oncoming spooge. Sunburst's eyes widened, and his spine arched backward as his belly pushed outward around the tidal wave. Flurry's gasping moans filled his ears as the thrashing, irrhythmic flexing of her shaft first pushed him forward—and then, slowly, but surely, lifted him from the bed entirely.

Sunburst's legs wriggled, his rump teasing its way this way and that. Shot after shot of thick, heady, musky spunk fired off inside of him. His belly continued to bloat; by now, it was spilling past his hooves, leaving him with the look of a mare ten months pregnant—with triplets. He looked like he'd swallowed a feast, guzzled a barrel of cider—and still, the flood came.

He was powerless to stop it; his hooves had been lifted entirely from the bed, his entire bloating body speared, then hoisted atop the filly's spasming organ. He gurgled, and then hacked up a wad of spunk onto his forelegs. Sunburst groaned. There was so much—

Hooves scrambled, pressed inward, struggling to hold his expanding stomach in. But there was no holding that bulge back anymore. Sunburst belched, a fresh glob of Flurry's cum expelling from his muzzle as his big, sloshing belly spilled over his hooves. It flopped against his thighs, its great, plump mass spilling down in an overhang as the squealing, squirming filly beneath him pumped him full of more cum—more cum!—more cum!

By the time Flurry's orgasm ran its course, Sunburst resembled little more than a great, bloated balloon speared atop her great shaft. He gurgled, then groaned. Lines of cum, thick and creamy, ran from the corners of his mouth to dribble down his chin. With a grunt, a heave, and a gasp, he wrenched his way off of Flurry's cock—and onto the mattress beside her.

Sunburst moaned. He was so big now—so full, so stretched full of Flurry's cum that he could scarcely feel anything more than the squirming, gurgling slosh of his gut as it struggled to digest its massive meal. His gaping asshole clenched, winked, his tail not even bothering to try and hide his spooge-streaked taint.

He whimpered, hooves trembling as he tried to cradle his gigantic gut. His legs didn't reach the bed, so great was its girth—it was like lying atop a water bed. He tried to rock his weight to the side, and only moaned with the sloshing ripples of flesh only stimulated his softening erection further. He heard somepony sob—was that him?—a gentle, muffled sob of pleasure, happiness, relief—and submission.

Some part of him pretended that the squirming, the sloshing he felt in his great gut was a platoon of foals. Healthy, strong, virile foals. His eyelashes fluttered, and Sunburst sighed as he sank into the fantasy.

But it was just a fantasy—wasn't it? For all that he could swear that he felt the sheer virility of Flurry's cum sinking into his organs, infusing them with her sex and vitality...he was a stallion. That wasn't possible.

But gods, the idea of it felt good.

With hooves barely reaching around two-thirds of his gargantuan gut, Sunburst blinked drowsily, and then glanced down to his side. Little Flurry was still lying there, her shoulders embraced by the great fluffy pillows around them. Her great shaft was softening, her mighty balls drained. The pillar of meat that had filled him so wonderfully was now becoming flaccid, its needs taken care of. Sunburst sucked in a breath when he felt it brush, then lean against his plump flank—and then sighed, his body relaxing.

He turned again to Flurry. The little foal was sleeping soundly, her cheek nuzzled up against the great, plush softness of his cum-filled belly. Sunburst smiled, then spared a moment to lick a dollop of cum from his own cheek. Whose it was, he couldn't tell—but as he sloshed it between his cheeks, and then finally swallowed, he couldn't help but shudder in erotic, satisfied pleasure.

A yawn split his muzzle. Rubbing at his drooping eyes, Sunburst spared a final, sleepy smile for the slumbering filly, and, with a soft shimmer of magic, drew her closer to his side.

There would be no moving her back to her own room now—nor would there be anything further to do tonight. Not while he was in this state, at least. But...

His eyelids drooped further. Sitting up here, perched upon a belly half the side of a bed... It was peaceful. Soothing. Yawning again, Sunburst closed his eyes, and nuzzled his cheek against his folded arms. Beneath his head, he could feel the soft gurgles and sloshes of his stomach, well-stuffed with Flurry's seed.

It had been one month since that night.

Sunburst still thought about it sometimes. He found himself staring after Flurry's stallionhood, at least on the rare chance that he caught her pulling it through the hallways. Once or twice, he'd pondered following the inevitable trail of precum she left behind, nosing his way forward and lapping it up before finally reaching the filly herself. He could see it now: He'd bury his face in her balls, pleasure her rod, then moaning, panting, present himself to be used for her satisfaction—

He swallowed. He was in control. Right?

And besides—he didn't need that anymore. Really. His marefriend had returned, and his needs were to be taken care of, just as he would take care of hers.

He'd waited for three and a half weeks for Shining and Cadance to ask him to foalsit again. They never had.

"Gosh," Starlight said beside him. She glanced around the towering vaults of the Crystal Palace. "This place really doesn't change."

Sunburst forced a laugh at that. "Six months isn't exactly a long time for an ancient palace to shift its foundations," he said. "And you've not changed a bit."

"Except"—Starlight shot him a smirk—"for maybe a little more magical punch. Thank you, Celestia's School for Gifted Unicorns!" She pumped a fist; Sunburst giggled.

Did he do that now? Giggle? He wasn't sure.

It felt...right

"And you," Starlight said, "certainly haven't changed a bit." She slung a hoof over his side—and paused when her foreleg sank into a bit of softness. "Well. Mostly."

Sunburst blushed. "Oh. I, uh, think I've been putting on a bit of weight, actually." He awkwardly removed her probing hoof from his flank—even that motion made his slightly-rounded belly sway beneath him. "I'm not sure how, I confess. I've been eating properly, exercising—"

"Well," Starlight cut in—"even with a bit of pudge, you're still cute." She gave him a peck on the cheek, and a wink; Sunburst blushed deeper as she went on, "I love you, even if you do get a little bit tubby."

"Actually," Cadance's voice rang out behind them, "he's pregnant."
