The little tan stallion walked home alone, his date having soured at the last minute. His friends had gone to the trouble of setting him up with a cute unicorn and at first they'd gotten along until they discovered at the last minute they were both bottoms, and neither was willing to top. The unicorn had kept insisting but Caramel had refused, and in the end he'd left, still pent up, hoping maybe tomorrow Mac or someone could give him some much-needed relief. And so he walked home, feeling a bit strange, but trying to put it out of his mind. He thought he'd seen a flash of magic as he'd left but it was so quick that he just assumed the unicorn was about to cast some kind of spell before giving up and deciding it wasn't worth it. In any case everything seemed normal. That night as he crawled into bed all Caramel could think of was a big strong stallion cuddling him to sleep.


The poor submissive stallion tossed and turned in his sleep, his dreams filled with stallions rutting him mercilessly. Their words sent him into a frenzy, each remark about how weak and small he was compared to his partners making him twitch and throb. But something was wrong - the stallions were shrinking. He could feel their cocks grow smaller within his ass and mouth as they stuttered and stumbled over their playful insults. Soon he could barely feel them thrusting at all and they were completely silent. Wailing in frustration, he bolted upright in a cold sweat from the nightmare. His cock was achingly stiff and his balls felt like they were swollen and heavy. Whimpering at his predicament, he frowned and slunk out of bed to take a shower and get something to eat. As soon as that was finished he made a beeline for Sweet Apple Acres, his need for Big Macintosh or any other stallion he could find to fuck him senseless leaving his cock hanging out of his sheath.


Mac was outside working early when Caramel came running over. His longtime friend and occasional fuckbuddy, Mac was the biggest, strongest, sexiest alpha stallion in Caramel's eyes, and he could be gentle as a lamb or as rough and rugged as sandpaper. Caramel preferred the latter usually. When the tan stallion slowed down to casually ask Mac how his day was going, the sun had barely been up for five minutes. Mac could tell his friend was a little on edge. "Rough night?" he asked. "The roughest, and not in the way I like. Do you uh...have a few minutes?" He cut right to the chase. Mac had barely started his work for the day, but with the rest of the family off in some other part of the orchard and the barn currently empty, he didn't see any reason why they couldn't slip off for a quick roll in the hay. Mac's own pendulous nuts hadn't been drained in a while. The excited smaller pony trotted on inside, his ass high in the air and tail up as Mac entered the barn.


Caramel flagged his tail to the side hard as he looked back up at the larger stallion. He lowered his front legs and clenched his thick ring in anticipation, letting out a shaky, voiceless moan as he prepared himself to finally get some satisfaction. Once the barn door was closed, the red draft pony smiled and slowly dropped out of his sheath. Inches turned to feet as the bigger stallion's cock poured out of him, Caramel licking his lips and watching it with bright eyes. Once he was out, he spoke softly at first, then more stern as he went on, "You did say you liked it rough, right? Then come get me hard, you little slut." Responding immediately to Big Mac's words, the tan pony rushed underneath him and began to eagerly lap at the yard and a foot of maroon cockflesh as he muttered a quiet, "Yes, master."


Caramel licked and sucked at Mac's dangling length until it stuck out proudly between all four of his legs. Then the smaller stallion lifted his tail once more as Mac thrust halfway inside in a single go, Caramel yelping at the sudden intrusion. He loved when Mac made him squeal. The large red pony then began to saw in and out of the smaller stallion, his heavy nuts battering Caramel's tiny grapes as he repeatedly hilted, the smaller pony's foot-and-a-half of cock bouncing up and down as Mac rutted his ass. Eventually the little stallion spurted a few globs of white onto his own front legs before feeling Mac's dick swell and flood his ass with pint after pint of fresh stallion sperm, more than a month's supply for a beta stallion like Caramel. As the larger pony withdrew his dripping cock from his friend, Mac noticed that Caramel seemed a bit...trimmer than usual.
 

Eyes wide, Mac rubbed them in disbelief at what he saw. The smaller stallion's body toned all over as he grew a few inches taller, mass simply packing onto his frame as his muscles rippled lightly beneath his skin. Behind, the pony panted and groaned as his testes quivered and sunk a full two inches closer to the ground, their weight and size surging larger before Mac's eyes. His erection flared and looked as if he simply unsheathed a little more. Catching his breath, Caramel turned to thank his partner and hastily made his way out of the barn. He hated to fuck and run, but he didn't have the heart to tell Mac that after getting such a mighty load out of him that he felt more frustrated than before. He had to find someone else. Someone who could give his subby ass a good, rough fucking. Someone to put him in his place with smug superiority and harsh insults. Someone to use his throat like a sex toy and laugh at him gagging on their cock.

Maybe he needed to find more than one top.
 

Caramel made his way over to the local stallion bar. Sure it was early but there were always a few guys hanging around hoping to get lucky at any hour. Caramel trotted on inside, quickly catching the eyes of a couple of large construction worker stallions. Within half an hour they'd shared a few drinks and offered to take the athletic-looking tan stallion home for some quick fun and a bit of coffee. When they arrived Caramel eyed his two prize stallions, asking which one was going to rut his subby little bottom and which preferred to choke his throat with his thick erection. Below him Caramel's two-foot cock hung excitedly as he presented his thick donut to whichever stallion wished to claim it.


Grinning, one of the workers moved to his ass and gave it a light swat with a forehoof. "Looks like we got a real cockslut on our hooves! What do you say we show him what real cocks feel like and stretch him out good?"

"You ream his ass and I'll make him gag on my yard long monster. And from the way his puny little cock's dripping at the thought of it, I bet he'll love every inch!"

Pressing his flare against that soft, yet strong ring of flesh, the stallion bucked hard and stuffed a foot of cock into his ass. It wasn't nearly as large as Mac's was, but it make him wail all the same. Taking advantage of his open mouth, the other worker rudely stuffed his erection inside, muffling his moans as the submissive pony lapped and suckled on the girth stretching his jaw. Both ponies worked quick to get every last inch into their new cum dump, Caramel's throat clenching and gagging as the stallion in front of him pushed himself down his throat. The feeling of his neck stretching as his nose bumped roughly against the pony's musky groin as his balls were battered by frenzied thrusts sent his cock spurting thick streamers of pre.


The two workhorses roughly used both ends of their little stallion slut, making Caramel nearly choke as one of them hilted his face, the other slamming into his and slapping the poor stallion almost hard enough to leave a welt. Caramel ate up their insults, loving every moment as the two larger stallions came together, flooding his ass and throat with a combined gallon of seed as Caramel's own cock spurted nearly a pint of semen. As the stick spunk coated his insides, Caramel rose up another few inches, now as tall and well-built as the stallions, his cock lengthening to match their own, although they didn't notice as they busied themselves switching positions for a second round.
 

By the time they'd gotten into a rhythm again, the poor sub could feel his newly swollen nuts aching even worse than before. It felt like every time he came and was filled with semen his need to get rutted and verbally abused was even stronger. Clenching hard around the pony slamming into his ass, he heard a shaky groan from the worker. "Nggghhh shit, this whore's ass is tight as h-hell. I thought you s-stretched this cumslut out? It's like a f-fuckin' vice back here!"

"Ggh I did! You watched me do it, idiot. It's not my fault you're a nggh nggh pansy like this fucktoy between us."

"Alright, that's it. This little ass is getting wrecked! You hear me, cumslut? I'm gonna pound you so hard you won't be able to walk for a week! Your ring'll be so stretched out that sissy little tail of yours won't be able to cover it up!"

Caramel came on the spot, several pints dwarfing his previous puddle as he hoped and prayed the boasting dom meant every word.
 

Caramel felt the stallion's stiff cock sawing in and out of his ass as their nuts collided repeatedly, while at the same time the stallion in front seemed like he wasn't doing as good of a job of filling up the tan pony's airway with his stiff meat. Caramel gulped and licked at the huge cock all the same, the stallion's resolve melting away as Caramel sucked him like a 200-bit whore, Behind him, the other stallion felt his cock being massaged by Caramel's anal ring as the hot, wet hole grew tight and loosened in waves. In no time at all the two stallions were once again flooding Caramel with cum, nearly gasping themselves as they were unable to hold back their thick loads from Caramel's expert ministrations. Suddenly their eyes popped open wide as Caramel's height surpassed their own by a head, the tan stallion's nuts swelling and lowering toward the ground as his now four-foot cock made him a match for Big Macintosh as the most-hung stallion in town. After the two stallions withdrew their still-stiff cocks at the sight of him, Caramel begged for one more rough fucking.


A little nervous from watching their slut cease to be so little, they couldn't resist the sight of his puffy donut clenching in anticipation. Standing side by side, they pressed their flares together and thrust forward together, grunting loudly as his thick ring gripped them hard and began to slurp them down. They were at a loss for words as his increasingly pleasurable anus pulled them in and milked their cocks expertly. Stammering, they tried their best to sling insults at the stallion, but the combination of his size and the pleasure of his incredible ass left them mumbling and moaning loudly. Looking to get them started again, Caramel tried to lose himself in his submission.

"Please, fill up my ass with your big, fat cocks and pound me until my hips give out! I need to feel your fat balls smacking mine and slapping the cum out of them! I beg you, leave me a crumpled wreck with a belly coated in my own cum and yours caked onto my ass and face! Tell me what a worthless slut I am, how all I deserve is to get roughly fucked by real stallions until my gut bulges with their spunk and I can't walk for days!"


The two stallions struggled to rut Caramel's ass, trying as hard as they could to thrust into the larger pony before his clenching butthole would squeeze their cocks just right and make them weak at the knees. Their quivering lips could barely spit out half-hearted insults at Caramel, telling him what a slut he was for letting them use him like this, secretly feeling like they were the ones being used as he continued to milk their erections with his gripping asshole. After several minutes they could hold back no longer, and Caramel felt another flood of warm seed as he grew again, rising to tower above his little stallions, their heads at his shoulder, five feet of intimidating stallion cock spurting over a gallon of seed, two fat balls that were the size of their two pairs combined and hung down over a foot in his loose, musky sack. The two construction ponies collapsed, completely spent, as Caramel ducked underneath the door and went off in search of somepony else who could really give his subby little ass the rutting it deserved.


As the now-beefy stallion galloped away in search of someone to dominate him and finally drain his still achingly-full balls, his mind raced to think of someone who could slake his lust. It didn't take long for an image of Big Mac to appear in his mind, his ass clenching as he whimpered and began to fantasize wildly about the big draft pony rutting him like a mare and grunting out the insults and demeaning words he needed so desperately to hear. Making his way towards Sweet Apple Acres, his five feet of thick girth bobbed and slapped beneath him as it spat thick wads of pre and left a slick trail behind him. With newfound strength, he burst through the barn doors and lowered his head, tongue hanging out of his mouth as he panted. But what he saw made his back knees wobble and his tail flag hard to the side.

Looking up in surprise, Big Mac's eyes grew to the size of dinner plates at the size of the previously wimpy Caramel. Then they immediately clenched shut as his cock spasmed and began to spurt thick jets of his seed. Caramel had burst in on his friend belly slapping along with a handful of other stallions to an image of his sister in a compromising position, Big Mac moments before climax just as the barn door practically exploded into splinters. Said photo was mostly obscured by a thick layer of semen from the other now-shocked males whose jaws were hanging loose from the mountain of muscle and cock breathing heavily with his ass hiked in the air.

"M-Mac please, hahh hahh I need you hahh i-in me!"

"nnghhhaah haah hahh... Caramel? Is that... you? How in the world did you get so, so big?"

"No! I'm n-not big, I'm a s-slutty little wimp of a stallion! Please, use my ass and p-pound me senseless!"


Mac stared at Caramel's beefy frame for a good twenty seconds before he finally made a move. Caramel's huge, ripped torso already made Mac look a little on the scrawny side, which was nearly unthinkable to the big red earth pony. His unwavering cock stood at full attention, though, and as he walked around Caramel, taking in the view of every bulging taut muscle , he made his way around to Caramel's swishing tail. His friend's newfound height made mounting difficult. Mac reared up as high as he could, but it wasn't quite enough. Maybe if he were a mare. But there were plenty of boxes lying around the farm. Mac pushed over an apple crate and stood on top of it, lining his erection up with Caramel's pleading ass. He slid in without resistance, then instantly felt Caramel's loose anus tighten up like a virgin filly's honeypot. The pressure was incredible. Mac's large stallion balls were resting on top of Caramel's, each as big as his pair. He tried to pull out, but Caramel's constricting grip was too powerful as his friend moaned with need. "P-plow my little bottom. Tell me what a needy little st-stallion slut I a-am." The others just watched as this titanic pony squeaked like a little filly while Mac stayed lodged inside him struggling not to cum right away from the pressure alone. One of them saw Caramel's enormous dick twitching beneath him, and approached it in awe. Caramel saw him move away from the group and stopped him before he could even bend his head down toward that meaty length. "Do you w-want to f-fuck my face and make me swallow your big, fat stallion cock?"


The stallion was taken aback, intending to submit himself to the obviously larger pony. Stammering a hesitant affirmative, he took a step back as Caramel knelt on his front legs and continued to babble in his absolute need to be used.

"P-Please, use my throat like your personal cock sleeve! Make me g-gag on your cock and rut my mouth hard like the little wh-whore I am! Show me what a real stallion's cock feels like and d-dump your load in my belly! Make my tiny little dick spit and t-twitch and laugh at my pitiful load as you flood my m-mouth with your hot, fertile spunk!"

Confused, the stallion watched as Caramel worked himself up and his impressive cock gushed a thick rope of pre onto the ground beneath him, the single spurt about the size of his own climax. But the confusion melted into a wailing cry of pleasure as the larger pony pursed his lips and pushed the stallion's entire cock into his mouth and throat in a single, practiced gulp. He shuddered and slumped forward onto his head, his hips trembling as Caramel swirled his tongue around the base of his supposed master's cock and slipped it out to lap at his balls. The pleasure was almost too much for him to bear and within a few seconds he was grunting and gasping, jerking fiercely as his erection flared and gushed hard.


Caramel gulped down the stallion's creamy load effortlessly and before their eyes his height crept upward, muscles swelling as his cock lengthened by another six inches. Mac felt the pressure around his dick intensify, gritting his teeth to keep from bursting as alternating waves of pressure rolled down his embedded cocklength. Eventually even the experienced draft stallion couldn't take anymore, unloading into Caramel's clenching asshole, another burst of height, muscle, and cock added to the already godlike Caramel's body. Mac stayed stiff as a board but the other stallion had slunk away to be replaced by one of his comrades. The head Caramel's six foot dick was now bobbing a few feet below his own chin, the gigantic cock as long as its owner's body as it spat pints of pre.

If Caramel wanted to be rutted like a mare, then Mac swore he'd try his best. He just wanted to see his friend spurt.


Gritting his teeth, Mac gripped his friend's growing rump with his forehooves and pulled his hips back as far as Caramel's vice-like anus would allow before slamming back into him all the way. The tan stallion groaned around the cock in his throat and his ring gripped his friend tight, the smaller stallion's balls sliding rougly against the larger's with a wet sound, both sets of heavy testes slick with musky sweat. Screwing his eyes shut and yanking back again, Mac began to rut as best he could, trying to ignore the unbelievable sensation of pounding Caramel's quivering and undulating ass by focusing on pure speed and force. Finally getting the rutting he so desperately needed, the hulking sub began to clench even harder, his cock spurting more and more pre all over the stallion whose cock he was currently using like a drinking straw. Mac stumbled and slipped off of his box as Caramel's surging testes knocked it out from under him, the cum spurting down the massive pony's throat sending him larger still. Regaining his balance atop the stallion's titanic balls, Mac felt his hips slam forward harder than he was expecting. The new growth packed even more power into Caramel's thickening anus, the desperate pony now unconsciously sucking Mac in with each thrust and pushing him out on the opposite stroke.


Mac tried to get his wits about him. His hooves were perched on Caramel's massive balls, the colossal stallion nearly double his own height and packing more than ten times as much stallion beef. Caramel's expert tongue was milking the other stallions in no time at all, and another tasty load followed, the titanic pony's cock swelling to seven feet. The next stallion in line had to climb onto the enormous flare to reach Caramel's face, the subby giant's lips wrapping around his length and nearly making him spurt within seconds. Mac could feel Caramel's ass pushing and pulling him more forcefully, loudly smacking against the enormous stallion's rump as Mac gave up trying to thrust on his own. Caramel was in total control, his body instinctively using Mac's to pound him hard enough to crack stone. Mac could feel the huge balls beneath his hooves churning with what must be a monumental load, Caramel's dick already belching up gallons of pre a minute, the floor growing slick.


Holding on for dear life, Mac felt his body jerk back and forth with incredible force as he cried out and flared hard. His balls clenched tight to his body as his cock began to erupt, thick jets of cum pouring out of his body even as Caramel's ass continued to force him in and out. His climax carried on for nearly 30 seconds before he felt a particularly powerful clench pop his still swollen flare out with ease. The seed inside him coupled with a fresh gush into his mouth sent him to dizzying heights, Mac able to lay back and catch his breath atop Caramel's audibly churning balls. Each time he inhaled the intoxicating musk pouring off of those balls filled his lungs and kept him almost painfully erect, his own testes pushed into overdrive from the pheremone-rich smell. Caramel began to whine as the spent stallion rolled to the side and slid out of his mouth, gasping and wheezing.

"N-No! Please don't tchhg tease me so bad, m-masters! Your subby little wimp of a slaaaggh haah s-slut needs to cum! I want all of you haah hahh to use... use me at once s-so you cannngh see my pitiful s-spurts and dwarf them with y-your own! C-Cover meeeeehhaah me in your hot s-spunk inside and out and m-mark me as your cum dump of a sex toy!"


The stallions around him couldn't believe their ears. This goliath pony was now at least twice the height of when he'd stormed into the barn and sporting a massive eight-foot erection, and he was pleading for THEM to rut HIM. Mac clambered down from his ball perch as he assisted three others in replacing him. It was a bit crowded, but probably not for long as their two and three-foot cocks slid into Caramel's puckering donut ring together. In front, standing atop the front half of his massive erection, three more ponies offered their dicks to Caramel's hungry lips, the excited slutty stallion stuffing his face with cockmeat. There seemed to be no room for Mac anywhere until he saw it, hiding in plain sight. The perfect hole for his four-foot monster. He pressed his flare against Caramel's, sliding in slowly. Caramel's bucking cock wasn't as powerful as his ass, but all the better for Mac to take charge and give Caramel the verbal teasing he craved. "I'm gonna f-fuck your cock and show you what a s-subby little slut you a-are!"


As the trio of stallions flailed in and out of Caramel's ass, the musclebound stallion's powerful ass flopping them around like ragdolls, he moaned into the three cocks stuffed into his mouth, swirling his tongue between them as he shuddered with pleasure. Mac's cock thrusting into the tip of his flare combined with his words got the sub so close to climax he could feel his swollen nuts churning and roiling with seed. Keeping up his assault, the red pony pounded as hard as he could as he continued to taunt and berate the huge stallion.

"I bet you nngh! love this don't you, nngh! cumslut! Getting spitroasted by ggh stallions just wasn't enough, mmgh so now you've got three NNGH thick NNGH cocks NNGH slamming your ass raw and another NNGH three NNGH fucking NNGH that whore mouth of yours NNGH and you still want more? A worthless spunk dump like you even needs his NNGH cock filled up in order to cum! I bet the thought of me using your NNMGH dick like an oversized rubber NNMGH cock sleeve and pumping my NNNMGHAHH load down into your NNMMGHAAHHAHH balls is making you NGGGAAAHH lose your mind isn't it?"

Nearing his own climax, Big Mac gripped Caramel's ominously swelling flare tight as he slammed home for a final time with a primal roar of dominance. The tan stallion shook as he felt the fat knot of flesh grow inside his erection just past the medial ring before the incredible heat of Mac's seed rushed down into his body. He felt his eyes roll back into his head as his friend spurted over and over, his cum mixing with the far larger load surging up from his clenched balls as he tried his best to hold back so he could feel every last second of Mac's climax within him. Faltering just as the red stallion began his final spurt, Caramel's legs wobbled and nearly gave out, a wall of viscous seed rushing up to meet the plug of flesh that was his partner's flare.

Now it was Mac's turn to tremble as his last gush was stopped midway by the oncoming tide of semen. With nowhere else to go and his urethra already stretched wide by his own seed, Mac howled as Caramel's orgasm forced the last pint of his cum back down into his balls along with several extra gallons of his friend's thicker, hotter seed. Slowly the pressure squeezed Mac outward even as he felt his nuts shake and bloat in size as cum packed back into them at an alarming rate. As their flares neared each other, the red pony's mahogany sac was almost three times its normal size and the nearly senseless pony felt like he had never cum in his entire life. At last Caramel's climax broke free and the deluge of sperm sent Mac sprawling backwards, his own cock geysering frantically has his stretched out cock and balls gushed as hard as they could. Minutes passed as Caramel brought the stallions penetrating him to orgasm after orgasm, blending them together as he bodily pulled cum out of them with the force of his ass and mouth. His own erupting cock gushed untold gallons of glue-like spunk all over Mac's writhing form, the floor of the barn turning into a musky white puddle. It took slightly longer than an hour for Caramel's swollen balls to drain completely, all six stallions splorting out of him and landing with a splash in the pool of seed, breathless and completely spent.


From outside the barn a faint clopping sound could be heard. Peeking through a window was a unicorn stallion, the one that Caramel had dated the previous night. His curse had been far more effective than even he'd dreamed, and now the titanic Caramel lay in a puddle of his own sperm, so massive and beefy he made Mac look like a colt by comparison, two gigantic wrecking-ball testicles resting in his sack, and a dick that even softening must have been measured in yards. And yet it wasn't really what he'd planned. Caramel was supposed to embrace his dominant side eventually and stop growing, but he'd remained a submissive girly stallion to the bitter end, only now with the body of a titan. But as the unicorn moaned and shot a huge load on the ground outside, dripping a trail behind him as he turned to head home, he reflected that perhaps this wasn't so bad after all.
