He tried to make sure he’d heard that correctly. “Da—dance?”

“Yup.” Vinyl’s horn shimmered. A smooth, electronic beat filled the air. An instant later, Whitewisp found himself going tumbling out of Vinyl’s grasp. He yelped, then landed on his ass with a thump. His massive cock smacked against his chest, leaving a smear of precum as wide as his hand across the fur there. He groaned, his balls aching as the force of the impact sent little ripples across their plump surfaces. Oh, Celestia, he thought to himself, staring up at his massive member in awe as his head spun. He was so...huge.

With a grunt, Vinyl heaved her bulk off of the couch. It creaked and groaned as she did so, and retained a significant depression where her ass had once rested. She drew herself up to her full height and stretched. Her body loomed over Wisp’s, even more so with his butt planted firmly on the ground. He watched her in awe as she slipped a finger beneath her shirt, grinning down at him the entire time, and tugged.

It split down the middle as easily as though it’d been made of paper. Now freed from their prison, her two massive breasts bounced free, looking even larger than they had before. She groaned happily, then crumpled up the shreds of her former shirt and tossed it over her shoulder.

One hand scratching the back of her neck, she made her way over to the dance floor behind the couch. She had a slow, easy gait, each one of her strides crossing almost twice the distance as a single one of his. The ground trembled beneath her massive feet; Wisp was almost afraid that she would crash right down through the floor. But whatever the room was made of, it’d been built with ample strength to support the bulk of its titanic owner.

Her hips swayed as she moved, her thick thighs rubbing together with every step. With another careless tug, she ripped her skirt off and tossed it aside. With that, her enormous ass was laid bare before him.

Wisp stared. Her panties did basically nothing but “conceal” her more private parts, and given the cameltoe he’d seen before, even that was a struggle for her. Her rump was massive, a pair of huge, globular spheres that shook and jiggled with the slightest persuasion. The string of her panties vanished somewhere inside the cleavage of her incredible ass crack, cutting deep through the canyon of that gigantic, glorious ass. One twitch of her hips sent waves of motion rippling across its surface, her Cutie Marks bouncing and shaking like they’d been born for nothing else.

Slowly, hypnotically, Vinyl drew to a stop—and then stomped to the side just as a low, bass beat thrummed through the stereo. She pivoted on her heel and whirled to face him, sending every part of her huge body bouncing and quivering in a dance of bountiful feminine flesh. Her panties concealed absolutely nothing, the curve of her puffy marehood showing clearly through their drenched fabric. It was...big.

Vinyl eyed him with a shit-eating grin. She held out a hand—slightly lower than for a normal pony, given that he barely even came up to the top of her stomach. “C’mon, little dude. I wanna see that thing shake.”

Wisp was on his feet in an instant. Then he stumbled, saving himself from tripping with barely a yelp and a pair of windmilling arms. Before him, the weight of his new member pulled him downward, a good twenty-plus pounds of pure cock that throbbed and twitched with lust. He could feel his balls dangling beneath it, pushing his knees apart as they swelled and sloshed with more seed. They were already the size of soccer balls, and he had little doubt that they were only going to get bigger.

Sure, it may have been hard to walk with that trio of monsters attached to his crotch. But did he really care? Another wave of simple, frustrated, needy pleasure surged through him, and Wisp nearly moaned.

The answer was pretty simple after that. No, he didn’t.

He waddled somewhat uncertainly over toward Vinyl’s crooked finger, his fat balls smacking against his thighs with every step of the way. His massive shaft bobbed and swayed from side to side, already looking more than half as thick as one of his legs. Had it been growing? It hadn’t looked that big when he’d cum down Vinyl’s throat. The simple memory of it sent it lurching with arousal, and he groaned. As he walked, he left a deep river of precum behind him, his throbbing shaft drooling more and more pre across the floor each time his nuts slapped together.

He took Vinyl’s hand gingerly. It was nearly twice the size of his own, and looked like it could crush his wrist with ease. He gulped, then glanced up at her. She grinned down at him—not unkindly, or even cockily—and just winked. The beat of the music thumped somewhere in the distance, just behind the roar of arousal in his ears.

“Alright, little stud,” Vinyl purred. “Let’s dance.”

One long arm reached down to squeeze his tight little butt, and then they were off.

Dancing with a giantess was...awkward. Wisp had no idea where to put his feet at any given moment; wherever he looked, it seemed Vinyl was just there, her big, amazonian body filling up every inch of space available. It didn’t help, either, that Vinyl seemed to have her own ideas on how he was going to “dance,” an act which seemed to require absolutely no input from him at all. She just hugged him tight and stepped, bounced, and shook to the beat, spinning him along until he was sweating and breathless.

This wasn’t ballroom dancing. This was...gyration. Wisp was reminded of the ponies he’d seen dancing outside, and then a throb of his cock against Vinyl’s massive thigh showed him just how pathetic those other ponies’ dancing was compared to theirs. Even the hulking bulges he'd seen at those other stallions' crotches were barely a foal's package compared to his; even the biggest tits on the dance floor outside were like a pair of pebbles next to Vinyl's enormous, bouncing bust. And her size—it was impossible to forget just how big she was as she manhandled him like a toy, groping for every part of his tiny body as she pressed him closer and tighter to herself. Vinyl was a force of nature, a whirling mass of size and libido and sex that tore his blush away and left him panting with raw, untempered need.

Vinyl Scratch didn’t dance delicately. There was no need to—and it was probably impossible anyway. A single step brought her breast smacking down against her belly; a twirl on her heel pulled his face forward until he was buried ear-deep in her massive, soft cleavage. She squeezed his erection between her thighs, grinding up against it until it reached up past her belly button, his thick medial ring rubbing tenderly against the slit of her dripping cameltoe.

Whitewisp groaned, losing himself in the “dance”. He found himself grinding back, humping her, feeling her. His hands wrapped around her waist in a pathetic facsimile of a foal dancing with an adult, his arms barely long enough to reach her Cutie Marks. Her fat ass went bouncing and swaying with each move she made, her whole body shaking like Jello as jiggles. A jiggling breast sent ripples down her belly, which sent her thunder thighs slamming together. And her ass…

He grunted, trying to reaffirm his grip on those massive globes. Vinyl’s ass was a behemoth in itself, a natural disaster of quivering, jiggling mass that seemed almost to dance independently of its owner. Wisp moaned, a splurt of pre from his cock painting the underside of her breasts a thick, milky-white.

“Mmff.” Vinyl grunted and pressed him closer to her. He could feel her breasts smushing together on either side of his head, could feel the steady throb of her pussy as it burned with arousal. “Not quite big enough, lil’ stud.”

The heat of her magic flared up around his crotch again. Wisp felt a moan bubbling up in his throat and let it go, his body trembling with pleasure as his stallionhood began to grow once more. Vinyl slowed down, but never quite stopped, her massive body swaying and jerking as his cock stretched to ever-greater sizes. It passed the top of his pectoral shelf, edging up past his chin as it approached his nose. It was a massive, quivering slab of meat, burning with a star’s worth of heated arousal, and drooling enough precum to fill bathtubs.

He could feel his balls swelling, contracting, sloshing as they grew along with it. His mighty shaft prodded against the bottom of Vinyl’s cleavage, then throbbed as it grew past it. It pressed between her breasts, a massive, shuddering member that didn’t push through them so much as grow past them. Its growth stopped somewhere midway between her breasts, his swollen, drooling tip lost somewhere in the marshmallow-soft mass of her incredible cleavage.

And then their dance began in earnest.

Vinyl stepped right; he stepped left. She squeezed her thighs together, and he slammed his hips forward, pumping his organ up through her soft, warm cleavage. Wet, sticky pre splattered against the bottom of her chin, then landed back down over her tits in thin, clear strands. She grinned down at him and grunted in satisfaction. A glimmer of her horn set the beat pounding even louder, and she groped his ass shamelessly, grinding her marehood even harder against his thick, veined shaft.

His hips jerked as they whirled, pumping his cock up and down her huge, jiggling tits. Each thrust sent another volley of pre splattering against her cleavage, his huge balls filling up fuller and fuller each time they smacked against her thick, rippling thighs. Whitewisp gasped in awe and pleasure as he felt Vinyl’s magic suffusing him. It was a heavy, erotic warmth that seemed to spread through every vein, every bone, every muscle of his body. His thrusts increased in intensity, speeding up until he was fucking Vinyl’s tits with each thrumming beat of the music around them.

Vinyl grinded against him, groaning and whooping as they jerked and swayed. Wisp felt the weight of her huge, massive breasts folding around his girth and found himself panting, his eyelids fluttering as his balls churned with a steadily-swelling load. Each jerk of his hips sent his cock thrusting deeper between her huge tits, its passage soon lubricated by the vast amounts of precum his organ was putting out. Gallons of the stuff, it seemed, matted her fur, smooth, sticky pre glimmering in a thin sheen around her dripping, bouncing boobs. Vinyl squeezed her breasts between her forearms and Wisp found his head jerking back, his tongue lolling out of his mouth as her tits squished tightly around his jerking, thrusting member.

And still, his balls grew. He could feel his nuts swelling, pressing up ever more tightly against his legs as he fucked Vinyl’s tits harder and faster. He thought he could see his tip poking up out of the top of her cleavage, a full two feet above his head. Only part of him registered that her nipples, tall, fat, and pink, quivering and erect with arousal, seemed...closer than they had before. Her breasts seemed only twice his weight now, rather than thrice that.

But Whitewisp was too busy to pay attention to anything silly like that. The weight of Vinyl’s soft, dripping tits wrapped around his throbbing member more pleasurably than the folds of any other mare’s cunt. The bulge of her clit felt smaller and smaller against the base of his shaft by the second, his cock swelling and bulging and gushing pre until he felt himself growing dizzy with lust and desire.

In a swift motion, Vinyl reached down and latched her fingers around his thighs. He could feel her thumbs pressing against his naked butt as she actually picked him up, heaving him into the air as his cock twitched and shuddered.

“F-fuck,” she grunted. Her fat tits bounced and jiggled as she forced his cock deeper between them. His huge, plump balls smacked against her cunt as she pushed him up and down, fucking her own tits with his engorged member. “N-not so little now, eh, stud?”

Wisp couldn’t even reply. He was in heaven. Vinyl’s breasts were so tight, so slick, so soft around his shaft that he felt like he was drowning with every lurch of his cock. His feet weren’t even touching the ground anymore; far above him, he could see the amazon’s horn glittering as she grunted and panted, holding him as easily as she would a child and using his massive dick to grind between her own breasts.

The ridiculousness of the situation hit him just as he reached his peak—and then, suddenly, it didn’t even matter anymore. Wisp gasped as he felt his nuts, now the size of volleyballs, slam against the bottom of his crotch as the retracted. He felt them churning, sloshing as what felt like gallons of thick, gooey cum mixed inside of them, the bottom of his shaft bulging as impossible amounts of seed forced their way up through his gigantic, shuddering stallionhood.

Wisp came like a volcano. He shrieked in pleasure, his hips jerking pathetically as his thrusts went wild, his tiny, weak body struggling to move the monster attached to his hips. A tsunami of jizz burst from his fat, drooling tip, globs of gooey spunk larger than his head exploding up into the air far above him. His huge cock bucked and lurched, his entire body jerking and twitching with the aftershocks of his climax as his enormous orgasm rolled over him. Ropes of spunk that never seemed to end rained down on them, splattering across his face, painting Vinyl’s mane and chest white, blinding them both as enough jizz to fill several bathtubs felt the pull of gravity and fell.

His balls swelled and contracted in equal amounts, their vast stores of seed sloshing within as his roaring orgasm did its best to empty them. Wisp’s back arched, his body writhing in Vinyl’s powerful grip as his nuts put out more in a single second than he formerly could have in a full month of jerking off. Her tits bounced and shook with each lurch of his titanic cock, jizz dripping down her bust and nipples as his incredible orgasm made it buck like a prize bronco. On and on it went, neverending, gallons of spunk rolling forth from his overstuffed nuts. So much cum! He felt a wave of pure white washing over his mind, drowning his thoughts in mindless, thoughtless pleasure, his whole body grinding, humping, twisting as his climax seemed to milk his groaning nuts dry.

And then it was over. With a whimper, he went limp in Vinyl’s arms. The warm, spongy surface of his member pressed against his face, her soft tits like pillows beneath his cheeks. He groaned, sweat streaming down his forehead as he felt his balls dangling beneath him.

Gently—surprisingly so, even—Vinyl removed him from her cleavage and set him on the floor. By some miracle, he managed to land on his feet, though it was no small feat to keep himself standing with the incredible weight of his member pulling him forward. His knees trembled and shook, struggling as much with the aftershocks of his incredible climax as with the mass of his new, enhanced stallionhood.

Behind him, he could feel Vinyl’s breasts pressing against his back. Hard, quivering nipples larger than his thumbs dug deep into his shoulder blades. The warm, slick coat of paint his cum had drenched them with smeared against his bare back, his fur growing even more matted with the evidence of his own pleasure. Wisp realized that he was panting, his chest heaving as his eyes fluttered weakly.

He felt Vinyl’s finger, sleek and smooth, gliding around the curve of his ballsack. He grunted, then moaned softly when she gave it a squeeze. His flaccid dick throbbed; as it softened, it draped over his medicine ball-sized nuts. It splurted one final glob of spunk onto the floor and then shuddered once more before falling still.

“Wow.” Vinyl’s voice purred in his ear, the music muted beneath its allure. Wisp shivered, tingles of pleasure and yet-aching desire spreading through his body. The warm and satisfaction of his afterglow had suffused every inch of him...and yet he could feel himself yearning for more. Wanting it, needing it. He could already feel his balls filling up again, his member chubbing up once more as Vinyl’s finger traced along its thick, veined girth in playful little squiggles. “Not such a little stud at all.”

He blinked blearily, his vision cloudy. Was that...the mirror he was staring at? He felt himself swaying woozily, still panting as he tried and failed to recognize the silhouette standing before him. Behind that form, he could see a vast white shape—Vinyl, he supposed, though she seemed somewhat less...hulking than before.

But how was that possible?

Vinyl snickered over his shoulder. Her hot, moist breath washed over his ear as she traced a finger lazily across his stomach. “Can’t say I’ve ever seen a colt take so well to my spell,” she chuckled, nuzzling his cheek. Her huge tits squished gently against his back, smooshing against his ass. He gave it a flex, and then shuddered when her nipples throbbed in response. “Mm. Maybe you’ll be the stud I’ve been looking for.”

He groaned. Dammit, why did his head have to hurt? “Wh-what do you mean?” he said, slurring the words.

She just chuckled again. “Why don’t you see for yourself?” she said, and gestured toward the mirror.
