Whitewisp stared at the stallion in the mirror.

The stallion in the mirror smirked back.

Hesitantly, he raised an arm and flexed it. The stallion in the mirror did the same, only his bicep was a good two times as thick as Whitewisp ever remembered his being. The simple motion made his chest flex along with it, his pecs bouncing slightly as veins tightened against the skin around his upper arm.

Whitewisp looked down. Holy shit. He had pecs.

He looked back at the mirror. The stallion—he—grinned back. His jaw slowly dropping, Whitewisp took it all in. His arms were thick and toned; another flex showed his bicep to be at least the size of an orange. His pecs were round and clean-cut, with cleavage that looked like it could snap his knuckles in half. He ran a finger down his stomach, staring. A perfect six-pack of abs stared back, smooth, rounded ridges that his hand bumped over.

That was when he realized that Vinyl was kneeling down beside him again. Except now, she didn’t tower over him by a good six inches. Instead, he could actually look down on her reflection—the top of her head only came up to the bridge of his nose. He blinked, utterly dumbfounded.

His massive cock throbbed. The fact that it still seemed grossly disproportionate to the rest of his body—no matter how much he’d grown—spoke volumes to the size he’d gained. He could feel it chubbing up further, growing stiffer by the second. Whatever he might have felt, it definitely liked what it saw.

And one thing was for sure: Whitewisp wasn’t much of a “wisp” any longer.

Vinyl’s finger trailed down the cleavage between his pecs. Wisp stiffened, then groaned, a soft moan of pleasure slipping past his lips as she squeezed his rounded, toned ass. “Told ya you were a stud,” she hummed. She winked at his reflection. “Just didn’t expect this much.”

“Wh-what happened to me?” Wisp continued to ogle his reflection in the mirror. Then Vinyl leaned slightly forward, her massive, cum-stained breasts pressing harder against his back. He grunted, his cock lurching and spattering the mirror with a wad of precum. It dripped slowly down onto the floor, oozing into a gooey, musky puddle below. He bit his lip and gave his other arm a flex. Holy shit, but it was huge. Nowhere close to Vinyl, but still!

She smirked. “Well,” she said, drawing the word out. She cupped one of his massive nuts in one hand and began to stroke his enormous shaft in the other. At its new size, she couldn’t even wrap her hand a third of the way around his monstrous girth. He felt rather inordinately proud of that, or would have if he hadn’t been too busy ogling himself. “My growth spells always have some amount of overflow. Looks like your body was more than happy to grow, though.” She gave his cock a squeeze and he gasped, every muscle in his body flexing and bulging to greater sizes as a bolt of arousal surged through him. “Which is awesome. I’m a big mare, and I need a big stallion to satisfy me.”

Her lips curled around his ear; he moaned as she suckled on it, tasting him. “Might be the biggest stud I’ve had yet,” she murmured, nuzzling his neck. He could feel his nuts swelling, sloshing with uncountable volumes of seed as her nipples pressed against his newly developed back muscles. “Gonna guess...seven feet, maybe?”

Holy fuck.

Wisp stared at his reflection for a few moments more. A huge, hunky, stud of a stallion smirked back. He placed both hands on the top side of his shaft and began to rub them back and forth slowly. He watched in amazement and lust as his arms flexed and pecs bounced, his shaft stiffening and rising up further with each inch his arousal added to it. By the time he was fully hard, it was long enough to reach his forehead, and thick enough that he could only barely wrap both arms around it.

Vinyl’s voice purred in his ear, low and throaty. “So,” she growled playfully. “Whataya say we move this to the floor and have some real fun?”

He spun so quickly his cock smacked against her breasts with a resounding slap! Pushing her cleavage and his own girth aside, he shoved his lips against hers. She grabbed him with both hands, pressing them even closer together as his member grinded between her spunk-dripping tits. Her tongue delved into his mouth, and he pressed back, their tongues dueling as hunger and pure, bestial need flared up in him.

“You’re mine,” Vinyl snarled, pulling back from the kiss. “You fucking stud.” And she grabbed him around the waist, picked him up (though not quite as easily as before), and whirled him onto the ground. He moaned, dazed, as his massive erection slapped against his chest and face.

She loomed over him, her massive form overshadowing him easily. His enormous shaft, nearing four feet in length, slid across her thigh, straining toward her dripping pussy. Vinyl smirked down at him, grinning through her cleavage, and caught his member between her thighs. Whitewisp choked, the plush softness of her legs enveloping his cock as she slowly slid down his length.

“Oh, yeah,” Vinyl purred. Wisp twitched and groaned, his impressive muscles flexing as the pleasure centers in his brain buzzed and whirred. Vinyl kept him easily in place though, licking her lips as she eyed his stallionhood lustily. “It’s been too long since I’ve had a real cock inside me.”

And with that, she thrust his flare inside of her.

Wisp’s eyes bulged. His biceps bulged, his core flexing as Vinyl took the first half-foot of his member inside of her without even breaking a sweat. She moaned, her tongue lolling out the side of her mouth as his shaft twitched and sputtered inside of her, a steady stream of precum leaking out the side of her pussy.

“Aw, yeah,” she groaned. “That’s the stuff.” And she shoved another foot inside.

Wisp found himself moaning, twisting, grunting as Vinyl slowly squatted down over him. As each of his turgid, throbbing manhood vanished into her cunt, he felt his balls swelling with ever-greater amounts of seed, more than ready to spill gallons of spunk inside his giant partner. He groaned, wishing for Vinyl to go faster, to take every inch of his cock and then more. He needed to rut, needed to fuck. A whimper slipped past his lips, sweat beading on his brow as Vinyl clenched her inner walls around his head.

She grunted, her eyes fluttering closed. “Mm,” she groaned, rubbing her belly. Wisp could make out the barest outline of...something there, a fat, rounded bulge straining against her coat. Her cunt spasmed around his cock again and he cried out, his eyes widening as he felt her stretching around his incredible length. “That really hits the spot.”

Vinyl continued to descend down over him. She kept rubbing her stomach, her palm moving in ever-widening circles as the bulge in her belly grew and grew. Wisp grunted, struggling to keep from orgasming right then and there as he watched that swell take on the unmistakeable curve of his flare, the indomitable bulge of his fat, throbbing cock. His nuts suddenly throbbed, and he groaned. He could actually see Vinyl’s stomach deforming around his huge member, her belly expanding outward as he gushed rivers of precum into her stretched marehood.

He barely even noticed when he bottomed out inside of her—or, rather, when she finished spearing herself on top of him. Her hips met his and he grunted in pain. His thighs flexed weakly against her massive, overbearing weight. He felt like he was being crushed beneath her huge, fat ass and incredible thighs...but he loved it. Her enormous breasts hung mere inches away from his face, bouncing and jiggling as the aftershocks of their impact rippled through them.

Wisp found himself panting. The pressure in his nuts was incredible; he felt like they were about to explode. His legs were spread far apart, and even that wasn’t wide enough to give his massive ballsack room enough to spread out completely. He felt his massive, heavy nuts pushing against his muscular thighs, their liquid contents sloshing and churning in anticipation.

His cock throbbed inside of Vinyl, and the two of them moaned in unison. Every inch of his impossible, girthy length was inside of her, each part of his sensitive mammoth of a member constantly stimulated by her warm, contracting, velvety walls. Wisp grunted as he felt the slickness of Vinyl’s walls sliding across his length, easily lubricated by the lakes of precum he’d been gushing inside of her and her own dripping arousal.

Her hands tightened on his pecs and he moaned. Playfully, she flicked one of his nipples, which was standing firmly at attention. She smirked down at him, pressing him harder into the ground with the weight of her incredible breasts. He could just barely make out the outline of the bulge in her stomach—the bulge from his member—pressing between her cleavage. It was enormous, easily two feet long and thick...and that was only half. He swallowed, feeling his nuts swell up even larger from the softness of her ass grinding against them.

“You ready?” she said, grinning. He just nodded, trembling with excitement.

And then she lifted her ass up over him...and slammed it back down.

He choked, his entire body lurching with the thrum of arousal that reverberated through his towering cock. A massive glob of pre larger than his head burst inside of Vinyl’s cunt, his massive shaft bulging as its output nearly doubled. She groaned, moving one hand up to rub against the outline of his shaft at her torso.

And then she did it again.

Up and down she went, forward and backward, side to side. The direction didn’t matter—all that mattered was the steady schlick-schlick of his massive, lubricated cock in and out of her clenching pussy as she rode him like a cheap dildo. He did his best to jerk his hips forward, to fuck her as steadily as she was him—but even with his enhanced muscles and size, she was able to easily keep him down on the ground with only a single hand on his chest. He was her toy, and she had no trouble letting him know that.

Each slam of her ass down against his hips sent his whole body shaking from the impact. He almost felt like he was being crushed, smushed to death beneath that amazing, gargantuan booty. If he hadn’t been writhing in all but indescribable pleasure, he might have been terrified. And her body...she was just so heavy. So huge. And yet even she seemed to struggle with the size of his cock, wincing in a combination of pain and pleasure as she drove his immense length inside of herself again and again.

“F-fuck,” she grunted, her massive knockers bouncing on her chest as she slammed herself down over him again. “None of those fucks out there have anything on you.”

He groaned, another splurt of precum splashing off the sides of her cunt as he felt himself twitch inside of her. “Wh-what do you mean?”

“I mean,” she snarled, “that you’re so fucking huge.” She slid her massive ass forward, crushing his abs beneath it, and then thrust herself back, filling her pussy with every inch of his mammoth member at once. She wailed in pleasure, panting as her lips spasmed and trembled as they were stretched wider than ever. “They’re good lays, but they’re fuckin’ tiny compared to you.”

Wisp just moaned. He could feel his massive shaft contracting inside of her, each pump of his length inside of her only driving his need to orgasm to greater heights. His balls felt so full, and Vinyl’s cunt was so soft, so warm, so...perfect. He needed to cum inside of her like he’d never needed to cum before. The size of his member had flooded his brain with hormones, his muscled, hulking body driven by roaring desires that he scarcely even understood. All he knew was this: He was in more pleasure than he’d ever been in in his life, and he never wanted it to stop.

On sheer impulse, the next time Vinyl’s mountainous bust came crashing down atop him on one of her downthrusts, he hugged one of them in both arms and pulled the nipple toward his mouth. He squished her fat tit between his forearms and latched on with his mouth, sucking at her breast as his cock lurched and flared inside of her. Her thrusts slowed immediately, her body moving to grind against his as he suckled even harder at her throbbing, erect nipple.

To his surprise, he felt a warm, sweet liquid rushing across his tongue. He gulped it down eagerly and found more following along behind it. More and more of Vinyl’s sweet milk cascaded down his throat, filling his belly even as he stuffed hers full of his meat. Vinyl moaned, groping herself shamelessly as she pumped his massive cock in and out of her. Wisp just drank, guzzling pint after pint of Vinyl’s thick cream as quickly as he could.

He squeezed her tit between his elbows and felt the gallons still sloshing within. Dribbles of milk began to run from the sides of his mouth, his cheeks bulging out as he found them filled with more cream than he could possibly swallow. A warmth, a rippling heat was beginning to rise in his core, spreading through every muscle in his chest and crotch. With a moan, he felt his erection beginning to grow once more, swelling in size as he suckled harder at Vinyl’s tit.

She groaned, kneading her breasts against the bulge in her stomach as it grew larger and larger. He could feel his balls filling up, the tightness and pressure inside of them building to impossible levels. His muscles bulged and thickened, his chest pushing out as his arms grew to the size of grapefruits. He could feel his body lengthening, his joints popping and muscles rippling as he passed seven feet and just kept on growing.

Vinyl was still huge, but was seeming less so with each passing second. The tightness of her cunt was overwhelming. Wisp threw his head back and gasped for air, letting sweet oxygen fill his lungs as cream dripped from his lips. His wings fluttered behind him, twitching against the floor as they stretched to a wingspan easily twice the size of what he’d had before. And above him, squeezing his sculpted torso between her thick, massive thighs, Vinyl grinned and began to ride him again.

Her weight was overbearing, but nowhere close to how stifling it’d been before. She was still in full control, yes...but he found that he could pump his hips against hers, driving his cock even further inside her abused pussy. She cried out, groping herself shamelessly as she folded her breasts around the cock bulge pressing against her middle. Her fat ass slapped against his crotch again and again, the sound of flesh smacking against flesh filling the air.

Droplets of milk sprayed out over Wisp’s face, covering his face in her warm cream. He licked it up, his mind buzzing with pure, mindless pleasure. He reveled in it: in the tightness around his massive, growing shaft; in Vinyl’s scent, so pure with sex that she may as well have been in heat; in his own masculine musk, so heavy and oppressive with arousal that he found he could scarcely think of anything else. He found himself awed with his own virility, groaning with disbelief as his nuts swelled larger with each smack of Vinyl’s ass atop him, those cum-sloshing spheres spilling over his muscular thighs as his arousal reached a towering, quivering peak.

Gasping, he felt himself bottom out inside of her a final time. His shuddering nuts froze—and then his cock was swelling, bulging with gallons of seed as they pumped more and more inside of it. It started at the bottom, a massive knot of jizz that forced its way past Vinyl’s tight pussy. Then, with a howl of pleasure, he let it all explode inside of her.

Cum erupted from his cock like a volcano, spattering against her insides in thick, gooey blogs. Gobs of spunk burst against her stomach, bloating it out with a tidal wave of spooge. His shuddering shaft lurched inside of her as the euphoria of release spread across his mind. Wisp whimpered and groaned, barely even struggling against his arousal as he came literal buckets inside of Vinyl’s dripping cunny.

With a holler, she followed suit. Her cunt spasmed, her insides clamping down hard around his shaft. He moaned, his massive cock letting loose with another volley, a cascade of jizz splattering against the sea of spunk already sloshing around in her gut. He could already see her gut bloating with his cum, turning round and taut and pushing her breasts upward as it expanded for more room. Shot after thick, gooey shot burst inside of her, his massive orgasm seeming to go on without end.

And then, groaning, she began to grow even larger. Her head loomed further above his; her tits swelled, her thighs, already thick, grew even plumper and more muscular, he could feel them squeezing around his torso as her spasming cunt milked his climax dry. His cock was erupting like a firehose, impossible volumes of spunk gushing inside of her as his orgasm. With each other spurt, he could see her belly swelling outward, then deflating, as though her body was struggling to process the incredible amount of jizz that was rushing to fill her.

She continued to grow, moaning in pleasure as her weight increased atop him. Her breasts expanded, her biceps thickening as she grew to tower above him once more. Her huge body shuddered above his, her own climax pleasurable enough for the both of them that he felt as though she were draining every last ounce of cum from his nuts, draining him dry to make herself all the huger.

And when it was finally done, she just groaned, taking a hold of her plump, sloshing gut in both hands and squeezing. With that, she stood up, still caressing her massive, cum-bloated belly as she slowly lifted herself off of Wisp’s massive member. He groaned mindlessly beneath her, drooling as aftershocks of pleasure burst in his brain. She smirked down at him, a steady stream of spunk gushing out from her stretched pussy as she drew herself up to her full, twelve-foot height.

She reached down and offered her hand; he took it, groaning as waves of pleasure crashed against his skull. It took some effort to heave his seven-foot body and five-foot cock off of the ground, but a giantess of Vinyl’s size and strength could manage it one handed. He swung to his feet, groaning and holding his head, as she drew herself back up.

Her horn scraped loudly against the ceiling. She looked up at it and glared, her lip curling. “Ah, fuck,” she said loudly. “Now I’m gonna have to go buy new clothes.”

Wisp almost burst out laughing right there. The ridiculousness of the situation was almost palpable. He was standing there, completely nude, equipped with a cock that was probably heavier than he’d been just an hour before and a seven-foot-plus  body bearing the muscles of a god. He’d probably added on a foot and a half of height in the past fifteen minutes alone, and more than a hundred pounds of muscle, and still here he was, dripping with his own seed, as a twelve-foot giantess complained about clothes.

A chuckle slipped past his lips. Then another. Before he knew it, he was laughing long and hard, a deep belly laugh that shook every muscle in his and set his fat nuts smacking against his muscular thighs. His wings shook and trembled behind him, flexing with a power and span that he’d only had in dreams.

“You need clothes,” he wheezed. “As if you’re going to fit inside any reasonably sized room anymore. I need new clothes. You need a construction company”

She grinned down at him. “Couldn’t let you get bigger ‘n me, now could I?” she said, flashing teeth. “But I gotta say...I’m looking forward to getting even bigger.” She groped one of her tits, and moaned when she saw that it now draped down over her waist. “Man, I’m fuckin’ huge. And from the looks of it, we keep doin’ this, we’re both only gonna get even bigger.”

“B-bigger?”

Vinyl flashed another smile down at him. Fuck. She was huge. A normal-sized pony would have barely even come up to her waist. And he still was only eye-level with her stomach—with her sloshing, bloated cum-gut that mere minutes before had been deformed by the massive organ draped over his nuts.

“You betcha, little dude,” she said, smirking. “You ‘n me. I’ve never met a colt who grows like you do, and I gotta say, I like the idea of breaking out of this place. So what do you say? My place could always use another repeat customer—or,” she added, purring, “another attraction.”

Wisp stiffened. His dick throbbed. In that instant, he had a vision: Himself, huge and musclebound, lying casually across a couch as a horde of attractive mares and stallions mooned over him, grinding against every inch of his body as an even larger Vinyl loomed and moaned in the background.

“Um.” All vital systems in his brain seemed to be shutting down. He could already feel his nuts refilling, and wondered just how long he’d need to go between orgasms now. “Um.”

She smirked. “Consider it, okay? Gotta say, if nothing else, you’ve got a cute butt.” She darted forward and pinched it—and then winced when the floor tiles crunched beneath her massive weight. “Right. Huge now. Gotta remember that.”

She recovered easily, hugging (or trying to hug) her massive bust to her chest. “There’s a big ol’ closet stuffed with clothes back there,” she said, nodding toward a back corner of the room. “Should be able to find something that fits you in there. I’m gonna go clean myself off in the meantime. And Wisp?”

He blinked up at her.

Her smirk widened. “Come back any time.” She turned, her massive, cum-filled belly bouncing and sloshing every step of the way. And then she squeezed herself through another door—though her massive breasts slightly deformed the doorway as she slipped through, and she had to bend over until she was almost on her hands and knees. And then she was gone.

Still somewhat awestruck, Wisp moved to the closet. It took him a good fifteen minutes to find something that fit, but once he had, he strutted back out wearing a shirt that looked all but painted on, and a pair of pants equipped with a pouch that seemed to bend all the way down past his knees.

He eyed his torn, ruined, jizz-soaked clothes lying on the floor with amusement for a moment. Then, shrugging a jacket on that left every inch of his massive biceps bulging, he stepped forward, his enormous package smacking against his thighs and rippling obscenely.

As he stepped through the door back into the main room of the club, he wondered in bemusement how long it’d be before he had to duck through to fit. A thrill ran through his chest, and he wondered what Crimson would say when he saw the new “him.”

Oh, yeah. He’d definitely be coming back soon.
