“How’s that, honey?”
Cadance groaned quietly. “Mm.”
Shining chuckled. He was crouched over Cadance’s back, one foot on either side of her. Around them, the sounds of the beach filled the air: crashing waves, shouting kids, chattering gulls. “Sounds like you’re enjoying this as a little more than just a safety measure.”
“Can I help it if my husband has magical hands?” Cadance smiled to herself. She spread her legs a little wider on the towel, careful not to let any sand get on. Her belly felt warm, and her back even warmer.
She groaned again as Shining’s masterful hands massaged her right shoulder. Officially, he was applying sunscreen to her—she’d always burned easily, and wanted to be able to enjoy her vacation without getting an itchy, peeling coat. Unofficially, she just loved letting him touch her—all of her—and in public, too. She’d been sick and tired of all the “propriety” that came with being the Princess of an empire. She was the alicorn of love, dammit!
And then, un-unofficially… A certain Twilight Sparkle was currently holed up on a sand dune a few hundred meters away, bearing a beach chair, a pair of sunglasses, and a set of binoculars. She had her eyes fixed on the bottle of sunscreen. She had plans—and it looked like the happy Royal Couple was playing right into them.
Cadance groaned a third time as Shining’s hands moved down to massage the sunscreen into her lower back. “Shiny, that feels good.”
“Okay,” he said. “Now you’re definitely enjoying this too much.” But he didn’t stop. If anything he just rubbed her a little harder, a little deeper.
Meanwhile, the potion that Twilight had left in the sunscreen went to work. Cadance squirmed atop her towel as a tingling spread through her body. She felt a warmth, beginning in her chest, and then slowly spreading out to fill her limbs. She squeezed her hands into fists, biting her lip as Shining squeezed her shoulders.. The tingling felt good.
Slowly, her body began to grow.
Her limbs grew longer, her shoulders widened, and even her chest began to swell until her already-generous breasts had pushed her chest a few extra inches off of the ground. She groaned, too lost in bliss to be concerned with a few extra inches.
It wasn’t until Cadance’s rear started to fill the space between Shining’s legs that he noticed the changes. He’d been crouched down on Cadance’s thighs, leaning forward and totally focused on his work, only pausing every so often to squirt another dose of lotion onto his palms. But as Cadance passed six-foot-six (from a previous height of six-foot-one) and hit just under seven feet, Shining had no choice but to take note of the wobbling, generous ass that was now growing and grinding against his crotch.
“Uh,” he said dumbly. “Honey?”
“Keep going,” Cadance mumbled.
“But—“
“Keep going,” she insisted. Shining just flushed and went back to work.
Back in the sandbar, Twilight had her right hand somewhere in between her legs. Her left held the binoculars up to her eyes so tightly that it might as well have been screwed in place.
Cadance had stopped inching, and was now definitely just plain growing. She squirmed and moaned, flexing her lengthening arms every so often as she passed seven feet, still lying down. Shining, preoccupied with rubbing, found his blush spreading across his cheeks as Cadance’s whole body grew larger, curvier, and even slightly more muscular beneath him. The second Cadance hit eight feet—which was, coincidentally, the instant that a nearby couple took notice of the growing alicorn—Shining’s swimsuit began to strain against his raging, hardening erection.
He started to thrust his hips a little bit, really grinding his package against Cadance’s larger—and growing—ass. He didn’t really have a clue what was going on, but whatever it was, he’d long since decided that he liked it. By the time she hit nine feet, only his toes were still in contact with the ground below him.
“Feeling a little frisky, huh?” Cadance mumbled, grinning. With a grunt, she slowly turned over—and darted to catch Shining as he fell off of her thighs with a yelp.
“What the—?” She looked him over, blinking. Maybe it was the fact that he suddenly seemed much smaller. Maybe it was the fact that she’d caught him in two hands, and was currently holding him just inches above the ground while sitting down. Or maybe it was the fact that she could only see the upper two-thirds of his body, with her newly magnificent bust more than obscuring the rest.
She blinked again, and then scowled playfully. “Twilight?”
Shining shrugged innocently. “Your guess is as good as mine.” The bulge in his trunks was more than just noticeable by now. If Cadance had to, she would’ve guessed that all thirteen inches of his stallionhood were straining and pushing against that poor little waistband. Then again…
She glanced down at herself. Sure enough, her bikini was more than ready to snap as well, having stretched far and thin enough that it seemed to cover her fist-sized nipples and private parts and just about nothing else. She carefully set Shining down on her lap—he looked so tiny and adorable like that, especially now that he was only two-thirds her size—and peered down at him over her big, round breasts.
“I’m guessing it was the lotion?” she said. Shining nodded. A smile spread across her face.
“Well, why’d you stop?”
Instantly, the blush was back on Shining’s face, accompanied by an ear-to-ear, wavering grin.
“Keep going?”
Cadance took both of Shining’s wrists in her hands (which was now laughably easy, her much larger fingers encircling his entire arm with little effort) and pressed his hands against her bouncing boobs. She grinned as sultrily as she knew how. “If Twilight wants a show, then let’s give her one.”
Shining nodded, too struck by his wife’s new size to possibly speak. Cadance lowered her eyes and leaned a little closer to him—and then seized him in her arms and hugged him to her chest. Shining could only grunt as he was pulled by force into Cadance’s bust, which could best be described as a heaven full of marshmallow clouds. So soft… And so warm.
He grinned goofily as she ground him into her boobs, each one nearly twice the size of his head. The only sounds he could produce were muffled groans of pleasure; the only movement he could make was a slight humping of Cadance’s perfectly sculpted stomach, his hips thrusting into her by reflexive arousal alone.
“You like that?” Cadance asked. She pulled him away from her chest, just to give him a second to breathe. Shining sucked in a greedy breath of air. His entire face was bright red, but the ear-to-ear smile he had showed that he certainly hadn’t minded feeling her assets up close.
“Very much,” he said. She almost laughed. He looked so small on her lap, so eager. So happy to please. And so, she noted with an amused look, aroused. She hadn’t seen her husband’s spear so hard and wet since their honeymoon. Maybe she should thank Twilight when this was all done, after all.
Though she had no doubt that the other princess was somewhere on the beach right now, probably pleasuring herself more than Cadance could ever hope to provide. More than Twilight thought she could provide, Cadance corrected herself. The Princess of Love never showed all of her tricks, not even to her sister-in-law.
But that was enough thinking about Twilight. Her husband was right here in front of her, horny, happy, and ready to please. And, besides—they had the attention of the entire beach. Why waste a perfectly good audience?
Cadance squeezed Shining’s shoulders lightly. “You still have the lotion?” she asked, her oversized hands roving across each muscle of her husband’s body. They felt at once tense and relaxed, as though the entirety of Shining’s body had been possessed by twin spirits of pleasure and lust. It wasn’t hard to admit that she felt much the same. Feeling her husband’s body like this, her every pleasure center lighting up as she squeezed her massive breasts lightly between her elbows—it would have been difficult to deny the tingle of electricity running up her own spine right then.
So, as Shining made to answer, she let one of her hands brush against Shining’s crotch. As large a stallion as he was, it seemed like she could have held most of even his package in a single hand. She gave him a little squeeze and smiled, just to make sure he knew it.
“I—yes, we do. And ohhhh.” He melted a bit at her touch, his whole shaft throbbing beneath her palm as the blush on his cheeks reddened. “I can...ungh...get some more.”
“More?” She raised an eyebrow. Her massage moved to his nutsack, gently rubbing his fat, sloshing balls. Each one was the size of an orange, easily, and the pair stood out even inside of his baggy swim trunks. She gave a small smirk of approval at the sight of his still-straining erection. “Oh, we won’t need much. Perhaps just another foot or so.”
“Guh,” Shining said stupidly. “Ungh.”
Cadance laughed lightly, withdrawing her hand. The sound was like tinkling bells, but had a throaty edge to it that promised something entirely less innocent.
“Let’s get out a little more of that lotion, hm?”
With a shaking, eager hand, Shining squeezed another healthy dollop of lotion onto his open palm. He looked up at Cadance; she smiled down at him and stretched her arms above her head. Long arms and legs cracked and popped as she reached up to the sky, groaning at the new distance her limbs reached. Shining stared up at her bouncing boobs, which Cadance had inadvertently thrust forward in her stretch, and, with their jiggling mass fixed in his mind, set about rubbing Cadance’s belly down with the lotion.
She was perfectly sculpted both from the growth and due to her own physique. Her hard, tight abs thrilled him, and the weight of her bust against his forehead was a constant reminder of his wife’s size and curves. The lotion was cool to the touch, but Cadance’s coat was warm, and Shining lovingly worked his fingers into his wife’s belly, eager to see more growth take place.
Cadance finished her stretch and groaned with pleasure as her smaller husband rubbed her stomach down. “That’s the stuff,” she grunted. She smiled down at him, and he smiled back up at her. On a whim, she reached down and took him in a hug, her thick, muscled arms squeezing him against her massive breasts.
“Nice and big, hm, Shiny?” She kissed the top of his forehead, then let her tongue slide against the tip of his horn. Shining just murmured something incomprehensible. “Hm? You like my girls?”
She jiggled her chest for emphasis, giggling as Shining squirmed deeper into her bust.
Shining Armor was in heaven. Twin mounds of supple titflesh were surrounding his face, and most of his upper body to boot. His dripping erection smacked against his stomach as it throbbed and throbbed again. His much-larger wife hugged him even harder to her chest, and began to grow.
Nine feet became ten, which only increased as Shining continued to rub more and more of the lotion into Cadance’s coat. She grew larger by the second, her massive frame increasingly dwarfing her husband’s. Then she groaned, a sudden pleasure surging in—of all places—her breasts.
She struggled through her haze of pleasure to look down over her enormous mounds. Shining, even while lost in his own reverie of pleasure and lust, had slapped his lotion-slick hands on the underside of Cadance’s bust and was currently rubbing them with all his might, smearing growth-giving cream all across her big, warm breasts.
Cadance gasped, her back arching slightly as an electric jolt ran up her spine. Though by now she had grown so much as to be nearly twice her husband’s size, her bust was growing even faster, her breasts swelling up until they nearly engulfed all of Shining Armor’s body with their mass—
Finally, the growth stopped, or at least slowed. Her body still tingling with a thousand pinpoints of pleasure, Cadance reluctantly removed Shining from between her breasts—the poor stallion actually drooling, his eyes wide and unfocused—and sat him right on top of them. In this position, he finally had the chance to look down at her again...but the fact that he’d been seated on top of her bust to achieve this position was certainly not lost on him.
“So,” Cadance said. She ran one enormous hand down Shining’s back and gave his hips a little squeeze. His cock throbbed appreciatively. “How’s this? Better?”
He took a moment to bring himself back to reality. His eyes now focused, and the drool hastily wiped away, Shining stared at his wife in wonderment. He reached down, anchoring himself in place by squeezing her the tops of her breasts.
“Cadance,” he said, completely seriously. “Honey, I’d be lying if I didn’t tell you that I’m currently more turned on than I’ve ever been in my life.”
“Oh? Even more than one our honeymoon?”
Shining grinned down at his giant wife. “If this doesn’t surpass that, it’s a close runner up.” He squeezed Cadance’s pillowy mounds a little harder, and she moaned quietly. “Whoever did this—whether it’s Twilight, Luna, or someone else—I think we owe them our thanks.”
“Mm.” Cadance smiled as her tiny husband leaned over and gave her a peck on the lips.
“And for all these ponies,” Shining said, gesturing around at the rest of the staring beach, “I think we owe them a show, don’t you?”
“Maybe,” Cadance said. She grinned wickedly. “But I think I owe my husband a show first.”
Shining gasped as she steadied him in place on her bust, leaned her head forward, and took the entirety of his cock in her mouth.
He’d always been larger than other stallions, and until that one lust-driven night with Cadance, Applejack, and Big Macintosh, he’d been the biggest stallion he’d known of. A solid thirteen inches of thick, flared horsemeat, Shining’s stallionhood had never been anything to sneeze at. In fact, during his first time with Cadance, he’d been worried about whether she could even take all of it. She’d gotten better about choking down all of his length—and even managed to deepthroat him most nights—but he’d always held a perverse sort of pleasure from the knowledge that he was almost too big for her to handle.
But now, not only was she so much larger than him—a fact that his masculine, testosterone-charged soldier side was still struggling to accept—but she was managing to swallow his shaft without even breaking a sweat. Where she’d groaned and grunted around his length before, Cadance was now just pure efficiency, her twice-as-large tongue slithering around and lapping at his throbbing length and delivering twice as much pleasure with each jerk of his hips.
From the look in her eyes, she may as well have been reading his mind. Shining grunted, his hips jerking as he let out a spurt of precum. Cadance slowed her slurps down, and finally pulled her muzzle away, a few drops of pre still licking from the corner of her mouth. She licked it up, her eyes still glittering.
“Looks like I’m big enough to take you now, Shiny,” she said proudly. “In fact, I might be too big for you, you poor little thing.”
Shining forced a grin onto his face. “Not a chance, dear.”
“Oh?” Cadance asked. “But I thought you liked it when I choked around your big, meaty cock.” She was purring now, her voice vibrating over his stallionhood like a deep, rich bass. “I thought you liked it when you bottomed out past my tonsils. I thought you liked it when you could blast your load right into my stomach.”
She tutted softly and reached up to take Shining’s cock in her hand. It seemed so small now—while Shining, rationally, knew that he was larger than most stallions, the way Cadance’s hand wrapped around it without any effort just made him feel small and undersized.
And somehow, though his cheeks were burning redder than ever before, he loved it.
“Now,” Cadance said. She was toying with his dick, poking it back and forth. Occasionally, she would extend her pinky finger and stroke his fat, full balls until they felt ready to burst. “Well, now you just seem so much smaller to me. So much more...manageable, say.”
She licked her lips and got back to work servicing him.
“Well, dear,” Shining grunted. That pleasurable haze was descending again, and he wasn’t sure he wanted it to leave. As long as it was there, he could brush off his sudden feeling of inadequacy—that creeping feeling of smallness. As long as it was there, all the beach could see would be a stallion on the ride of his dreams, rather than a stallion dwarfed by his giant of a wife. But would the second part really be that bad? “I—unf—don’t think I’ve ever been—ungh—classified as manageable. And if I were—“
He never got to the end of his hypothetical. Before he knew it, his hips were jerking wildly, slamming again and again against Cadance’s vast, pillowy breasts as he had the best post-blowjob orgasm of his life. Cadance just gulped it all down, her enormous throat muscles working to easily take in every single drop of Shining’s seed.
Her eyes half-lidded, Cadance slowly pulled her muzzle away. Shining groaned, his head lolling back. Shining’s cock throbbed one last time, leaving a rope of cum trailing from his tip to his giant wife’s lips. Cadance just licked it up and smiled.
“How’d that feel, honey?”
Shining pulled himself together. His cheeks reddened. “Good!” he said, quickly. Too quickly. Cadance’s smile widened.
“Good to hear,” she said. She lifted one plate-sized hand and began to fondle Shining’s cock. He may have cum already, but he’d never been a stallion to finish after just one go-round. She’d always appreciated him more for that. “But, truth be told, I don’t think I found it rather satisfying.”
Shining’s cheeks were burning now. He glanced around the beach, biting his lip. Cadance found it actually rather adorable. “Honey, I—“
‘I’m sorry, dear.” Cadance mussed Shining’s mane, her enormous palm easily managing to cover his entire head. He suddenly felt very, very small. “But it’s just a sad fact of life that a mare of my size can’t properly enjoy a stallionhood that small.”
From the second the last word left her mouth, she knew she’d misstepped. Suddenly, Shining couldn’t quite meet her eyes. The redness had moved to cover his neck as well. She saw him swallow, saw him flinch away for a second, and instantly regretted her words.
But she wasn’t done yet.
“However,” she said quickly, “that doesn’t mean that it has to stay that way. After all, we have our own custom-made growth potion, don’t we?” She reached into her bust, found the bottle of lotion there, and pulled it out. She held it up to Shining and smiled apologetically.
Apology accepted, it seemed. Most of his blush disappeared. The shame was gone in seconds, to be replaced by more than just a glimmer of eagerness. Cadance almost laughed.
“Not that we’ll be applying any to the rest of you,” she said, grinning mischievously at him. “I rather enjoy looking down on you, and you’re simply adorable when you’re small.” She squeezed him against her massive breasts, each one nearly two-thirds his size. He grunted loudly, though certainly didn’t protest. “No, I think an application to your stallionhood is just enough. A generous application, that is.”
Shining’s face lit up. “Well,” he said, drawing the word out. Cadance nearly giggled. She knew this act—it was his “fake reluctance” act. He wanted to be persuaded, did he? “I don’t know. Seems to me a bigger dick would be a little unmanageable.” He gave his footlong a little pat and raised his eyebrows. “Maybe you’re just too big.”
He was going to be persuaded all right. “Oh, please,” Cadance said, her voice teasing. “You’ve always loved being bigger than all the other stallions. Get even bigger, and nobody could even hope to challenge you.” She leaned toward him, lips brushing across his. “Imagine it, Shiny. A cock big enough to fill up even my new marehood. A cock so big that it sticks up over your waistband soft—a cock so big that when you get an erection, it bulges against your shirt and pokes against your chin.
“And I know you love messy orgasms,” she murmured. “Imagine a load coming from a pair of nuts the size of melons.” Or the size of these breasts, she mentally added. She kept that bit to herself. Didn’t want to scare him off, or at least not yet. Maybe later, when he was too horny and too huge to say no...
“Mm,” Shining groaned, as Cadance finished and moved to suckling gently on his shoulder. “Honey, that sounds…”
She pulled her head back with a sloppy pop, smiled down at him.
His face was shining. “Fantastic.”
The cap to the lotion came off with a pop. Cadance squeezed a generous dollop into her palm and settled Shining back onto her lap. This wasn’t the time for half measures. She wanted a dick she could use.
Shining swallowed as Cadance took his dick in hand, the lotion squishing loudly against his shaft. “Ungh…” he grunted. “Honey…”
Cadance’s enormous palm covered the entirety of even his thirteen-inch cock. She barely had to move her fingers to work the lotion in. Then again, she decided, he deserved a little something more after the embarrassment she’d just given him. So she curled her sausage-thick fingers around his member, squeezing and rubbing to maximize both absorption and pleasure.
Shining groaned again. His dick had felt small before, but now, with Cadance taking it all in hand, it felt absolutely tiny. But something made him put that feeling aside—a growing sensation of warmth centered around his crotch. Already he could feel his member stiffening, the veins swelling with blood as his balls churned and filled with seed.
Cadance smiled as she worked the last of the lotion in. Shining’s member felt silky-smooth to the touch, which, she admitted, wasn’t quite so bad as far as side-effects went. Still, she was more looking forward to the main course. She licked her lips as she saw Shining Armor’s cock throb once—and then begin to grow.
“Mm,” she said, smiling. Shining’s cock had begun to grow; if she didn’t know better, she would have said that he was getting hard. She watched, licking her lips, as his flared tip poked out of the hole between her forefinger and thumb, smirking as his smooth cockflesh began to push against her tight grasp. “Looking good, honey.”
Shining grunted, grinning. “Heh. Y’think?” He glanced down at his dick, and his eyes widened. “Holy cow!”
It was worth the exclamation. While it had been unofficial before, it was now nearly official that Shining Armor possessed the largest stallionhood in all of Equestria. Eighteen inches of throbbing, dripping stallion-meat throbbed against Cadance’s palm. As they watched, transfixed by his growing mass of dick, it throbbed again and surged up another four inches. It inched its way up Shining’s chest. He groaned as the head rubbed up against his sculpted pecs.
Two feet. It was bumping up against his chin now. Shining shifted uncomfortably on Cadance’s lap as it prodded against his muzzle, the tip dripping with copious amounts of precum. It was positively drooling with pre, the thin, milky-clear liquid pooling at the top of his shaft and running off the side onto Cadance’s wide, voluptuous thighs.
When Cadance had repositioned him, she’d done it so that Shining’s back was to her, his head leaning gently against her pillow-like mounds. Now she watched the stallionhood creeping up toward her with a glint of hunger; watched it pass Shining’s muzzle in height; giggled as he gave it a tentative lick; flushed with need as it passed his horn to reach a final, awe-inspiring height of three and a half feet.
Shining grunted, struggling to keep his pleasure under control. He’d never felt more aroused in his life. His pillar of stallionhood towered above him, and while he felt a rising sense of pride at the sight, some part of him noted that he was feeling very small again. Not that he minded.
He squeezed his eyes shut as his cock gave a mighty throb. It was swaying in front of him now, bobbing lightly without any outside stimulation. Yet somehow he could still feel a building heat at the base, a growing need to spill his seed. He groaned as his balls, each one easily eighteen inches across and weighing heavily on his lap, churned and sloshed, the ocean of cum within building and swelling until it could be held back no longer—
He threw his head back, the back of his skull sinking into Cadance’s soft, massive breasts as his cock flared and erupted, flinging at least a half-dozen thick ropes of cum skyward. He watched them with awe even as the pleasure washed over him. Each rope of spooge was as thick and long as a regular stallion’s shaft, and by the time his cock had finished “squirting”, he had no doubt that he’d just cum over a gallon of seed.
Panting, Shining let his head sink even deeper into his giant wife’s bust. He glanced up at her and grinned. She smiled back, that familiar hungry glint in her eyes.
He knew that glint. It meant I’m going to fuck you silly, and there’s nothing you can do about it.
“What do you think?” he asked, trying to sound casual. He stifled a laugh when he noticed a thick rope of his spooge clinging to his wife’s muzzle.
Cadance licked it up and swallowed. “I think,” she said, her voice low and throaty, “that this is much. Better.”
And with that, she picked Shining up with both hands—hoisting him as easily as she would a teddy bear, even with the added weight of his new cock—and slammed him down onto the beach.
Shining grunted, all the wind knocked out of him. His enormous cock slapped against his chest and face with the force of the impact, hammering him even further into the sand. He swallowed, watching it bob back up to its full height far above him. He’d always been a taller stallion—six foot two, plus a good amount of muscle—but next to a dick more than half of his size, he must have looked very silly indeed.
And it was just so big. He gulped as he watched it sway. It filled almost the entirety of his vision, a forty-two-inch long cock that was as wide as his smaller shaft had been long. A drop of precum was already beading on the tip, as large as a small colt’s head.
For the first time since acquiring his new tool, he realized something. He wasn’t going to be fucking Cadance so much as it was his stallionhood that was going to be fucking her. She’d outgrown him, and his package had outgrown him too. He was a tool, a toy, an accessory to a magnificent pillar of stallionhood and an enormous, bountiful specimen of femininity. Yet, somehow, he couldn’t bring himself to care. It only made him more aroused, and soon his cock was pouring out a steady stream of precum, which had the happy side effect of well-lubing it as well.
A shadow fell over him. Shining looked up past his swaying cock and gulped. The sky had been blotted out, leaving behind nothing less than the gigantic silhouette of Cadance’s rear. Each asscheek could have held a foal comfortably; each Cutie Mark was the size of his head. Her butt had always been one of her better qualities: round, soft, and plush, with a curve that pushed her hips a good three inches to either side of her waist. It looked like a thirteen-foot Cadance had grown an ass to match: an enormous pair of muscled, yet soft, asscheeks that a stallion could lose himself in.
Shining noticed that he was drooling, and hurriedly slurped it back up. The last thing he saw was that enormous, godlike rear descending upon him, and a massive, winking pussy slowly widening to fit the tip of his cock—
—and then he was inside of her, his flared head stretching her wider than she’d ever been stretched.
Cadance let out a wordless cry. Gods, but she’d never felt so full, even at her previous size. Shining’s member had grown enough to more than give her a match. The head alone was giving her trouble, and as it slipped inside of her, her massive thighs flexing as she squatted over her husband’s length to control her descent, stretching her cunt to the max.
“Oh, gods, Shiny,” she moaned. She slowed for a moment, lifted her ass a few inches then lowering it back down. Shining’s flared head rubbed against her clit, setting her whole body on fire. “You’re so big.”
Had he been capable of any higher brain functions, Shining Armor would have said much the same. Yet with his giant of a wife filling his sight, and his cock exploding with pleasure, he had precious little power to devote to any kind of speech. Instead, he just lay limply, his muzzle hanging slightly open. “Mwragh.”
Cadance let herself slip down a few more inches, her massive thighs spreading even wider as she struggled to take him in. She finally came to the medial ring—a bulging mass of thick, dripping cockflesh even wider than Shiny’s waist—and forced it inside of her. She moaned all the louder, everypony on the beach helpless to do anything but stare as the biggest mare in Equestria took its biggest cock.
Her enormous hips slammed onto the ground, unsettling the sand for a few yards around and nearly crushing her much-smaller husband beneath them. He gasped even as his cock throbbed inside of her, hilted in Cadance’s enormous pussy right to the base. Her walls clenched and squished around him as he filled and stretched her to the brim.
She began to fuck him methodically, coming out of her squat before crashing back down. Her eyes nearly rolled back into her head as she forced his cock all the way inside of her. Her hips pumped smoothly up and down as she rode, not him, but his cock. His magnificent, enormous cock. Up and down she went, clenching and rolling, her breasts bouncing against her chest with each impact.
Shining had his arms wrapped tightly around his wife’s ankles, struggling to hold on as she fucked him senseless. Every sense was screaming at him as waves of pleasure washed over him and filled his veins. A larger wife had turned him on more than ever before, and a much larger stallionhood had magnified the pleasure a thousandfold. He heard somepony shouting, heard somepony moaning and grunting and spitting. It was a moment before he realized that that somepony was him.
Every time she came down on him, her magnificent ass slapped loudly against his balls, which just set them sloshing even louder with seed. They almost looked bigger than they had mere moments before, swelling and churning, with more and more of his seed ready to spill. She had him pinned to the ground, and was grunting and snorting, going harder, faster.
Cadance felt so stretched, so full. It was almost a painful sensation, but it was a good pain, like stretching a muscle. She hadn’t felt like this since their honeymoon. She could already feel herself accommodating his size, though, could already feel her lust and arousal growing to a peak. Every time she came all the way up, an overwhelming sense of emptiness, of a yawning need to be filled, washed over her. Tingles of electricity washed up her spine, accompanying a growing feeling of tautness, of wetness, of warmth—
Shining grunted, squeezed his eyes shut. He could feel his massive balls retracting toward his body, could hear them churning louder than ever before as the tension at the base of his dick grew and grew and grew—
The pressure in his loins exploded.
Cadance gasped as she felt Shining’s cock flare up inside of her. She could feel his tip prodding against her walls, could feel the bulge steadily moving up his shaft until it stretched her even wider than before. There was a burning fire in her belly. It flared up higher and higher as she went over the edge and fell into orgasm. Her inner muscles clamped down on Shining’s cock, lodging it in an ironclad grip as the bulge inside of her just grew and grew and grew. Her hips jerked wildly as she came and came again. Her sweet nectar streamed down the sides of Shining’s shaft—but thanks to its immense girth, not a drop escaped her tightly clasped cunt. She was sweating, panting, moaning, caught up in a wave of pleasure that seemed to melt the world away.
Her vision went white as she reached the peak of her orgasm. And then Shining’s orgasm began.
His cock flared impossibly wide inside of her, and then gallons and gallons of hot, thick spooge were flooding inside of her. Shining snorted, whinnying as his stallionhood pumped copious, impossible amounts of cum inside of his giant of a wife. He struggled against the weight of his massive tool, his hips jerking pathetically as he tried to ride out his orgasm.
He blasted out load after load of cum, gallons of the stuff spilling out of his massive, swollen balls. Cadance moaned with every sticky rope that hit her insides, her whole body writhing as her cum mixed with Shining’s inside of her. Finally, Shining’s orgasm tapered off, each load of cum slightly smaller than the last, until it was just barely leaking seed into her.
Cadance groaned quietly, one plate-sized hand going to her belly. She grinned to herself as she felt the bulge there. She must have looked pregnant—at least six months, even, with the massive load that Shining had just pumped into her. Squishing her big, cum-filled belly, she gave a soft moan as she felt his seed sloshing inside of her. She licked her lips as a warm afterglow spread through her body. That was more like it. That was the fucking she was used to getting from her husband.
Unsteadily, she got to her feet. Her dripping pussy slid off of Shining’s cock with a pop, small streams of spooge and femcum still running down the sides. With a groan, she fell to the beach beside her husband, her massive body creating more than a bit of a disturbance in the sand.
He opened two bleary eyes. “Hey, honey,” he croaked. “How was that?” His massive cock had shrunk a bit, leaving him with a flaccid tool of a mere two feet, rather than the forty-inch-monstrosity he’d had before. “Good enough?” He wet his lips, the last surges of pleasure inside of him slowly fading.
Cadance smiled and extended an arm around him. She cuddled him to her massive bust, his body sinking gently between her breasts. “That,” she murmured, “was perfect.”
Shining chuckled suddenly. “Think Twilight enjoyed that?”
“I think we gave her a show.” Cadance rolled her eyes. “Not to mention all of the other lovely people at the beach today.”
Shining nestled his head a bit further into her bust. “Let ‘em stare. Let them see how big and beautiful my giant wife is.”
Cadance curled her arm a bit more tightly around him, pulling him in like a teddy bear. His flaccid cock flopped over her wrist, still dripping. “Not to mention how sexy my stud of a husband is.”
Shining chuckled. “Think we should think about asking Twi for a reversal spell?”
Cadance considered that for a moment. “Hm. Well, I must say that I’m enjoying being large far too much.” She hummed to herself. “I’d love to see the looks on the nobility’s faces if I return to Canterlot or the Crystal Empire like this.”
“And my giant dong?”
“You know it.” She gave it a playful squeeze. “It might be a little unwieldy—“
“—a lot unwieldy—“
“—but I think you look good with it.” Cadance grinned down at him devilishly. “My husband, strutting around the palace with a bulge in his shirt and pants larger than most stallions can only dream of.” And you’ve always been a bit of a showoff, she added to herself with a silent giggle.
“I could be okay with that.” Shining looked up at her and grinned. “So. Bigger for now?”
Cadance laughed. “Bigger for now,” she said. She craned her neck and gave her little husband a peck on the lips. Then she held him close to her chest and relaxed, the two of them listening to the sound of gulls and waves washing up against the beach.
On a sand dune several hundred meters away, Twilight Sparkle gave a final cry as her last orgasm ran through her. Her binoculars, which had been hovering in front of her for the past half hour, crashed to the ground as her magic momentarily blinked out. She licked her lips, a grin coming to her face as sweet juices ran over her hand.
Oh, yes. This had definitely been a fun idea.
Idly, she wondered if she might be able to persuade Rainbow Dash to come to the beach next week.
