Intro: A Heated Night

Equus ferus caballus.

Luna read the scientific sounding name, mouthing the words, her eyebrow rising slightly, then her gaze fell on the rest of the small sheet of paper.

The horse, or Equus ferus caballus, is an Equine creature native to the human world, closely resembling our Saddle Arabian cousins, but with a few major differences. For one, horses are said to lack pony-like cognition.

Luna snorted impatiently. She already knew all this.

They are strong, great with manual labor, and make for great pets.

The Lunar Princess groaned, her eyes rolling in their sockets, before landing on the short report again.

They are also fond of apples.

The writing ended there. Luna turned the paper around, wondering if Twilight had written something on the back of it, but the scroll was barren. She looked back at the couple of lines, her brow furrowing. Was this what passed as a joke in this day and age?

“I cannot believe this.” Luna let the small scroll fall on her work table, the alicorn grabbing a quill and ink pot to write a hasty reply, whispering out loud as she scratched the back of the parchment. “It would seem our sister’s penchant for japes and other tomfooleries hath rubbed off on you, friend Twilight Sparkle, and we appreciate your quip. Hahaha.” Luna’s eye twitched, her quill almost puncturing the paper as she wrote the last ‘ha’.

“But we would ask thee, nay, beg for you to give us all the information you possess on our un-Equestrian cousins. You are the only one to have travelled to the human world, thrice now, you have to know more. Help me Twilight Sparkle, you are my only hope. By the Moon’s light, your friend, Princess Luna.” Luna carefully spilled sand on the scroll to help the ink dry up, tapped the missive clean then rolled it back up. She took the scroll in her navy-blue aura, applied her seal, before closing her eyes as it disappeared in a flash of green fire.

Luna reclined back on her chair, looking out her window; Equestria was fast asleep, the full-moon high in the sky, bathing the land in a soft tint of blue. Usually the sight would fill Luna with a deep sense of peace, but tonight it only served to aggravate her; she should be out there, helping her little ponies in their dreams, not stuck in her room like a grounded foal. She squirmed in her chair, the reason for her dereliction of duties trickling down her thighs: for a few days now she had entered her estrous cycle, making concentrating on her dream-walking next to impossible. She was used to her body becoming more sensitive, her loins becoming slightly moist with pheromone-laden drips, but this time it was completely different.

This year her heat was stronger than ever before, and she had little choice but to bear with it until it ended. For days now her royal slit was positively drenched with arousal, the heady liquid constantly running down her thighs, her ethereal tail damp with her juices. Her nethers were constantly twitching in need, a blaze raging deep in her belly, her marehood winking obscenely wide at the worst of times. Her scent was also incredibly potent, as she had found out on the first day of her heat.

On that morning, she had not realized she was leaking everywhere when she woke up, the Lunar Princess always groggy before her coffee, and after a quick shower she had paraded in front of her bat pony guards like she always did, heading to the royal dining room to eat her breakfast. She had heard the thestral stallions stir strangely as she passed by them, the sounds of sniffing and whimpering escaping their usually stoic muzzles. When she had looked back they were completely still, their impassive expressions intact, but as soon as she turned the sounds returned. She was too tired to think much of it at the time, and she had made a note to review her troop’s discipline later.

Like always, her sister was eating dinner when Luna made a great entrance in the dining room, the guards and servants bowing as she approached the table. Celestia had smiled her kind smile, her lips opening to exchange her usual pleasantries, but before she could say anything her nostrils had flared with a surprised snort, a look of utter shock spreading on her white muzzle. Luna glared at her sister, watching the solar princess sniffing the air like a dog, convinced the alicorn was preparing one of her incessant pranks; she had made sure to examine her chair for any pins or whoopy cushions before sitting down. Strangely enough, the maid who brought her cup of coffee was blushing profusely, the mare refusing to meet her gaze as she set the steaming mug before a her. Luna had watched the mare scurry away suspiciously fast, and she sniffed the contents before taking a careful sip of her coffee.

It was her favorite grind, black as the night and bitter as could be, free of any tampering. She smiled, taking a bigger gulp, before her eyes were drawn to her sister once more; she then paused, mouth full of hot coffee. Celestia had the look of a rabbit cornered by a fox, her usually white cheeks now a deep crimson, and she looked about to faint. Her nostrils kept flaring wide, as if smelling a delicious cake being baked, a wince crossing her muzzle whenever she did so. Slowly, Luna had put her mug down, her cheeks puffed out as she gave her sister a questioning look. Celestia whimpered, squirming in her seat, before taking one hoof from under the table, pointing towards the solar guards lining the walls. Luna carefully turned her head, completely confused, and she followed Celestia’s indication, watching the solar guards squirming strangely, as if needing to go to the bathroom… and what was that bobbing under them…

She had almost choked on her coffee when she had spotted the first engorged stallionhood swinging under a burly armored pegasus, and she had spat the hot liquid all over the place when she realized all of the guards were sporting impressively swollen erections, some of them already leaking precum from their flared tips. Outraged, she had jumped from her seat, intent on admonishing the stallions for their lack of control… but her seat had jumped with her, as if glued to her flanks. Only then did she realize her rear was completely drenched, a waterfall of her own juices falling from the dripping chair, her arousal already forming a large puddle on the ground. She had remained frozen in place for a few excruciating moments, the silence only broken by Celestia’s incessant sniffing and the loud slaps of cock meeting armored belly.

Luna had prayed for the ground to open up and swallow her whole, but in the end it was her sister who came to her rescue, teleporting them both to the royal baths before she could humiliate herself further. Celestia had placed a clothespin on her muzzle as she helped clean her sister, scrubbing with a loofa like when they were just fillies, Luna too mortified to speak.

The incident had been classified top secret, so of course everypony in Canterlot knew about it by now; ponies were awful at keeping secrets. The papers had a field day: “Princess Luna tries to seduce ALL the royal guards at once, hundreds end up in the hospital for acute priapism.” Lies and slander! Only fifty or so had been afflicted with dangerously persistent erections, all had made full recoveries! Mostly.

Luna had tried everything to keep her scent contained, but anytime she walked out her room the same happened: stallions’ nostrils flared, sniffing the air like hungry hounds, their cocks slipping from their sheaths instantly, and mares blushed and scampered away, as if scared off by the strength of her scent. The worst was her sister; Celestia avoided Luna like the plague, the Solar Princess wearing a silly looking gas mask whenever they had to meet. The situation was just ridiculous.

Now confined to her room to avoid turning the castle into a mess of erect cocks, Luna had turned to the only thing that could distract her from the burning need in her nethers: research. She had plowed through a month’s worth of magical theory papers, had caught up on the recent history she had missed while on the moon, and had generally slowly lost her mind. Nothing could satisfy her heat: she had tried toys, magical stimulation, hypnosis, mediation, yoga… She groaned, remembering that particular idea, and how disastrous it had been. Really, it was the yoga instructor’s own fault, he had been the one to insist she used the tight-fitting yoga pants. Not her fault the nose-bleeding and… blood redirection had made him faint like that.

Luna was distracted from her dark musing by a swirling puff of green smoke, the emerald cloud swishing through the open window to hover over her nose. With a loud *pop* a new scroll appeared out of thin air, falling into Luna’s waiting magic. She quickly broke the seal bearing Twilight’s cutie mark, spreading the parchment on her table, eager to get some answers. She was sorely disappointed.

“Deepest apologies...” Luna read, mumbling to herself. “Lack of time to research the subject while on earth…” Luna’s eyes were back to twitching. “Only thing I know is that horses can be found on farms… That’s it?” Luna exhaled loudly, leaning back in disappointment. The motion made her swollen pussy rub against her chair, and she gave a short surprised moan. The fire in her belly roared to life, demanding her attention. Now panting slightly, she hurried to scrawl a ‘thank you’ to her fellow princess, wincing when her insides clenched, her oozing cunt begging to be filled. She quickly sent the note back with a flare of her horn, and she almost threw herself at her bathroom door.

One extra cold shower later, Luna emerged with a sour expression, her mane still hanging wetly against her neck. She had half a mind to just lay in her bed with a tub of ice-cream and brood, until a glint of light reflecting on a shiny surface caught her attention. Still grumbling at herself, Luna stomped to her desk, shooting the photo a distracted glance, a shiver running down her damp spine. This photo was the cause of her sudden interest for earth horses: it was a vivid image, sharper than any photo Equestrian technology could produce, showing a human girl with a fiery red head riding on a fine specimen of Equine maleness. Celestia had sent her the photo alongside a letter, the alicorn gushing about her Sunset Shimmer growing up to become a hero, Celestia declaring how proud she was, hoping they could be reunited soon. Celestia had obviously hoped to distract Luna with the mystery that was Sunset Shimmer -was the filly her niece? She certainly looked the part, but Celestia never denied nor confirmed it- but Luna, in her heated state, had focused on something else entirely.

The horse was tall, his long legs powerful and strong, muscles rippling under his sweat covered coat. His mane was wild and unkempt, giving him a gruff look that no stallion on Equestria could hope to match. And to top it all off, the picture clearly showed a large pair of low hanging testicles frozen mid jiggle while he strutted, a long sheath jutting from his taunt belly. The fact that this fine specimen was just an animal in his world did nothing for Luna’s estrous crazed mind: her body only saw a stallion big enough to mount her, with a package clearly big enough to satisfy her, and balls plump enough to extinguish the fire in her belly.

Luna managed to tear her gaze away from the enticing sigh, just a little disgusted with herself; what would the papers say, if they knew their Princess got wobbly around the knees for an animal? But still, her curiosity was piqued. She didn’t know if it was her heat talking, but she found the horse’s gaze to hold a hint of intelligence, more than one would expect from a simple beast. Luna had asked for any precisions Princess Twilight could give her when it came to these horses, but the purple alicorn had never actually seen one of them, and her human friends had been understandably wary to give her much information about an animal so close to her original species, one humans treated as beasts of burdens. Luna scratched her chin; if her hunch was correct, horses could actually be intelligent beings, the humans willingly enslaving them, or, more likely, unable to recognize their language.

Luna had to be sure. Plus, this would be a perfect distraction from her heat.

Snorting resolutely, Luna shook herself dry, her mane billowing out to its usual ethereal volume. She stomped to her balcony, trying to ignore the first dribbles of arousal running down her leg, and she focused on her mission. She had been locked in her room for too long, it was time for her to stretch her wings, and finally feel useful again.

Luna took a running start and launched herself into the night sky, her vast wings catching a strong breeze; she had missed this dearly. She soared gracefully over the sleeping city of Canterlot, enjoying how the chill wind felt against her feverish coat, the full moon embracing her in its cool light. She grinned, momentarily forgetting about all her issues, and she banked towards the Everfree Forest.

Riding the Pony

View Online

One thing to note when it came to opening rifts between dimensions: the magical surge always leaves scars in both realities. When Twilight Sparkle had gone mad with power -the human Twilight that is- and had torn portals all across Equestria, a few of them had remained open after she was defeated. Celestia and Luna had been quick to repair the damage, but that didn’t mean a tear couldn’t be opened back up, if you knew where to look.

Luna stood before one such tear; the fact that it was situated in the Everfree Forest made it especially difficult to seal completely, and the princesses had been forced to place a few spells around the doorway to keep it secure. If anything was to break the seal by force, they would know. Thankfully, Luna was one of the few who knew how to undo the spells quietly; she didn’t want Celestia to come breathing down her neck after all. The process took longer than she expected, her concentration constantly broken by her nagging heat, but she had the portal open nonetheless.

She slipped inside, her horn flaring as she let the spells close the breach behind her; she didn’t want anything from the Everfree to slither into the human world after all. Luna’s hooves clattered noisily on the harsh pavement as she stepped into the human world, her ears swiveling on all sides to make sure she was alone. The night air felt stiffer than Equestria’s, and it had an unpleasant smell to it, but at least the full moon was the same, welcoming Luna into this new world. She looked everywhere, but there weren’t any humans around: the plaza was deserted. She craned her head back, staring at the edifice in front of her, a banner announcing its name in big bold letters.

“Canterlot High…” Luna murmured, looking at the school with a small grin. “So this is what passes for our grand Canterlot Castle in this dimension, hmm?”

The Lunar Princess turned, her ears flattening on her skull as her hooves made a racket against the pavement, and she eyed the base of the nearby statue, home of the mirror that housed the main portal to Equestria. Taking this portal would have been safer than taking the unstable tear between dimensions, but she would have also become a human. And she had to admit she was in no hurry to inhabit her human counterpart’s body. How could one stand upright with such long twiggly legs? Also, she wouldn’t have her wings.

Luna’s wings flared open, and one mighty flap later she was airborne. She quickly flew into the sky, watching with wide eyes as the human housings stretched as far as the eye could see. It was all concrete and steel, but she had to admit that the view had its own charm, the dots of light creating a giant spider web; no place in Equestria could match this. Luna ascended until she could see far and wide, the alicorn gliding in a circle to try and find something that looked like a farm; who knew what human farms even looked like? Her nocturnal vision pierced the darkness, and she quickly found something promising.

She could see fields to the east, the harsh concrete giving way to pastures and small clumps of trees that could barely be called forests. And between the large expanse of wheat and maize, Luna could see barns, silos… farms! The alicorn grinned wide, and with a mighty flap she shot towards the farmland, a dark blur against the starry night.

*******************

Luna had been gliding over the fields for some time now, her eyebrows raised in surprise; she could almost think this was Equestria, the wheat fields and orchards very similar to what she knew at home. Of course, the machinery she saw here and there was completely alien to her. The huge machines almost looked like giant beetles, sleeping amongst the fields, and she was half tempted to land and poke one of them to see if it stirred.

Then, a sound cut through the silent night. A neigh, loud and clear.

Luna’s ear quickly swiveled, locating the origin of the sound, and she banked to her left. She circled over a peculiar looking farm, her keen sense of hearing telling her that she had found what she was looking for. Luna folded her wings, the alicorn plunging towards the earth like a falcon, wind screaming in her ears. She waited for the last possible moment then opened her wings wide, her fall turning into a graceful landing, her hooves softly touching down on the packed dirt.

Luna looked around herself, her ears still perked up; she had landed between two large buildings, and she could hear Equine chittering coming from both sides. She hesitated for a few seconds, then she chose the smallest stable. The front door was locked, of course, but one quick flap of her wings and she soared through an opening in the roof, avoiding a pulley, darkness surrounding her as she slipped inside, her hooves landing on something soft.

The soft nickering instantly stopped, the horses now aware of her presence; she could hear shuffling around her, large shapes moving in the darkness. Luna closed her eyes for a few seconds, letting her eyes adjust to the gloom, and when she opened them she almost cried out in surprise. There, just a breath away from her muzzle, a great big snout was sniffing at her curiously. Luna took a few steps back, her rump hitting something warm and fuzzy; she flittered to the side skittishly, looking around nervously. She had landed in a huge holding pen of sorts, the floor covered in a bedding of shredded straw. And, surrounding her, all looking at her intently, stood a large herd of Earth horses.

Luna’s eyes widened in excitement, watching in awe as the big Equines milled around her, admiring their build. They had beautiful dark coats, coal black with a nice shine, their fur short and well groomed. They had lithe bodies that reminded her of the running athletes at the Equestria games, but with an aura of physical power about them; she could see muscle rippling under their shiny coats. Their form definitely resembled the Saddle Arabians, even more so than the horse in Celestia’s photo, down to the shape of their muzzles. They were all taller than her, and she had to crane her head back to look the closest Arabian-like beast in the eyes. Just like she had thought, his gaze harbored a spark of intelligence, but from this close she realized it was the same kind of intelligence one saw in a smart dog, not a fellow sapient creature.

But still, it didn’t hurt to try and communicate with them. The stallion she had bumped into was the tallest by a fair margin, he was clearly the strongest too, his chest rippling with taunt muscles whenever he took a breath, his snorts deep and dominant. From the way the other horses gave him a wide berth, he seemed to be in charge, or at least was a figure of authority around here; she would start with him. Luna carefully approached, eyeing the great beast with interest.

She cleared her throat, then extended her hoof tentatively. “Greetings, we are Princess Luna of Equestria, we cometh in peace.” She put on her most diplomatic grin, wondering if it would answer her.

The Alpha tilted its head to the side, sniffed at her hoof, then resumed its silent staring.

Luna sighed, looking at him more carefully, the stallion staring right back; and he was quite clearly a stallion, oh Equestria he was. She shook her head, tearing her gaze away from his underside, and she slowly stepped closer.

“Thou really cannot understand my words, can you.” She gently placed her fetlock against his cheeks, trying to gauge his reaction; the horse only pushed against her leg, sniffing her fur, a burst of air exiting his nostrils. “Hmm, seems dear Twilight was right after all.” Luna scratched his neck, the horse softly nickering under her touch, clearly enjoying the attention. “Shame.” She sighed, disappointed.

Luna flicked her tail, turning around to give the rest of the herd one last look; her phantasies of swooping in to rescue her earthling brethren were thoroughly dashed. Plus, if they had been intelligent, she wouldn’t have minded courting one of them, particularly the Alpha; they truly were fine male specimens, all of them… Luna’s brow furrowed, her gaze sweeping the surrounding horses more carefully, finally realizing something.

Were they all stallions? She looked under every horse, and they were all obviously male, with their sheaths in full display, their ballsacks swaying between their thighs…

Luna blinked, realizing she was staring again, and she tried to look away from the enticing display. She flapped her folded wings against her sides, fanning herself; was it just her or was it starting to get hotter in here? Maybe she ought to get out of the gloomy barn, get some fresh air; the atmosphere inside was certainly stuffy, what with the body heat radiating from the Arabian horses, their strong breaths coming from all sides, and the omnipresent stallion scent. It was like a hoofball-team locker-room, but with a much more bestial undertone. It wasn’t unpleasant, if Luna had to be honest…

A muzzle landed on Luna’s haunches, rubbing her coat quite inappropriately, and she squealed in surprise at the unexpected contact. Looking over her shoulder, Luna grumbled at the stallion currently nuzzling her rump, the Arabian making strange nickering noises; it was part rumbling and part snorting, she had never heard an Equine make those sounds before. She scolded the overly friendly animal, “Bad horse, bad” then stepped away, gently flicking the tip of her wing against his snout. He seemed perplexed at her action, his eyes slowly blinking at her, a look of utter disappointment on his face. Luna didn’t have much time to dwell on his strange behavior, as a second horse started to rub his neck against her back, making the same strange noises.

Luna grunted as she pushed the animal away -by the moon were they heavy, and strong!- and she squealed like a little filly when she felt a third one give her rump a playful nip, just over her cutie mark. She instinctively prepared to kick the horse away, but the animal seemed to expect it, the great beast jumping away with an amused whiny; they were quite limber, despite their great size. Luna gave her flank a quick glance, making sure her coat didn’t sport a bite mark, but her eyes were drawn to something else entirely. The horse that had nipped her rear was presenting his side to her, showing off his muscles, his legs stomping the ground as he strutted in place, and from this profile Luna had a clear view of his underside.

The stallion was quite obviously aroused, his cock flopping about as he pronked happily. Luna’s cheek exploded in a deep blush, her eyes following the bobbing stallionhood. It was mottled light-pink, veins pulsing under the surface, and it was huge. It stood to reason that their equipment would be proportional to their size, but this was ridiculous: he was bigger than any pony Luna had ever bedded -she only knew of one that could even hope to compare- and he wasn’t even hard yet! His cock was still slipping from his sheath, the fleshy pole swinging from side to side as it grew longer and longer, still limp but already monstrous.

Luna gulped, her eyes widening as she remembered a few little details she had not accounted for: she was still in heat, her pheromones were capable of sending even a stoic royal guard into a rutting frenzy, and she was surrounded by a herd of feral stallions. One quick look around gave Luna an idea of the trouble she was in: no matter where she looked, she could see cocks emerging from their sheaths, some of them already starting to harden, drips of arousal landing on the straw bellow. Luna could smell their excitement now: it was everywhere, the scent of virile stallions slowly saturating the barn, the open loft door high above doing very little to disperse their scents. And, lost in the pheromone laden cloud stood a wide-eyed Luna, the alicorn in heat swaying slightly, as if drunk on their musk.

Luna’s mind had blanked out, a trail of saliva dripping from her open mouth as she tasted the air, her eyes focused on the surrounding cocks. She whinnied in surprise when a stallion nipped at her other side, her brain kick-starting with a screech: she had to get out of here! Luna scrunched her face in concentration, trying to teleport away, but she could barely summon a few sparks. The fire in her belly had blazed into an inferno, and she whimpered in shame as her pussy winked wide, a spray of female arousal squirting on the straw bedding, spreading her heated scent. The reaction was instantaneous, the ring of stallions nickering in excitement as their cocks surged with new vigor.

Luna watched in horror as the forest of stallionhoods rose in tandem, limp flesh throbbing to life alarmingly fast, the Arabians’ cocks jerking with steady pumps of excited blood, growing in size with each bounce. Before long Luna was surrounded by a ring of fleshy spears, all pointed squarely at her, the horses’ once calm gazes now burning with feral lust. Luna shook her head, trying to clear the fog in her mind, and she looked up; the loft door, still wide open, she could see the moon calling to her. Luna squared her hooves, spread her wings, prepared to launch herself skyward…

A muzzle suddenly pressed into the base of Luna’s tail, teeth gently nibbling her sensitive dock, and the poor princess cried out as she stumbled on the ground. Luna flailed on the straw bedding, her wings kicking out like a downed bird, and she struggled to get her hooves under her. Luna sneezed as the bedding got into her nose -it turned out there was sawdust mixed with the straw- but she eventually managed to stand back up. A few of her feathers were out of place, but it shouldn’t be an issue. She spread her straw-covered wings, but again, before she could fly to safety, she was rudely interrupted; nibbling on her ear was just unfair!

It seemed almost like a game to the Arabian horses. They kept nipping at her coat, nuzzling her rump, grazing her flowing slit with their snouts, tasting her, and Luna had no choice but to jump away from one side of the ring, only to bump into the opposite, where more eager muzzles awaited her. By now her royal pussy was absolutely drenched, her folds engorged with need; she could feel her cunt winking constantly, her flagging tail letting the excited stallions see her flesh displayed in invitation. Luna didn’t know what to do anymore; she couldn’t use magic, she couldn’t flee, and she couldn’t fight these powerful creatures. It was only a matter of time before one of them got impatient…

As if reading her mind, a younger looking stallion detached itself from the herd, his cock slapping against his belly as he approached. Luna tried to shy away, but the Arabian pressed against her side, his long neck draped over hers. He was one of the shorter ones, but he still stood taller than her, and she could feel his strength as he tried his best to keep her from squirming away. She felt his long cock slap against her leg as he struggled to mount her properly; he was clearly inexperienced, but he made up for it with youthful enthusiasm. Luna bit her lips, her mind in chaos as reason warred with lust, a little moan escaping her lips whenever the young stallion’s cock missed its mark, hitting her inner thighs.

She was just about to angle her rear -whether to help him or throw him off, she didn’t know for sure- when a low and powerful whinny echoed around the barn. The young stallion recoiled in fear, his barrel sliding off her back in a hurry, and he rushed to rejoin the surrounding herd. Luna looked around in confusion -and just a little bit of disappointment- and her gaze fell on the Alpha. The imposing stallion had remained stoic while his herd had toyed with Luna, but now he was advancing on her with purpose, his intent obvious; Luna almost whimpered in fear -and arousal- when she saw the size of his stallionhood, the deep black rod bobbing under him.

Luna tried to keep her distance, the two of them circling each other around the circle of stallions, the alicorn doing her best to keep her rear away from him; it meant she received a fair share of nips and intimate nuzzles, but at least the Alpha couldn’t mount her. Not yet at least. The tall animal seemed to enjoy the sensual dance, his eyes never leaving Luna’s as he slowly closed-in on her. His confidence only stoked the burning desire in her belly, her instincts screaming at her to just turn around, bend over, and let him do as he pleased. Luna shoved those thoughts away, her thighs now drenched with arousal.

Suddenly, the Alpha’s powerful hind legs kicked out and he jumped in front of her, cutting her circling path. Luna tripped over her own hooves, her rump hitting the chest of a watching stallion as she stumbled backwards. She huffed in surprise as the stallion behind her reared back with an eager whinny, his chest sliding over her rear as his hooves grabbed at her flanks; he was certainly more adept at this than the previous young stallion, Luna could feel his cock pressing against her swollen slit as he shuffled on top of her. Before he could thrust inside however, the Alpha thundered into him, breaking them apart. Luna was thrown to the ground, the alicorn scrambling to get up while the Alpha put his underling in his place; maybe she could escape while he was distracted.

But as soon as she was up he stood right next to her, his sides pressing against hers; she tried to shy away, but his powerful neck embraced her, keeping her close, his snorts blowing her ethereal mane away. From this close Luna had no choice but to inhale his scent; his musk was incredibly potent, making his virility quite obvious, he smelled of straw and just a little hint of sweat. His dominant presence made Luna’s pussy gush with excitement, her body clamoring to be taken, the alicorn’s hips swaying to bump into his instinctually. Yet, the stallion didn’t try to mount her, like the younger horse had.

The Alpha caressed her neck, his muscled chest pressed against her shoulder, his legs gently nudging hers. He made those strange chittering noises as he embraced her, his strong heartbeat pumping against her; she didn’t know if this was some sort of mating ritual, but she had to admit that it was working, her body responding to his advances. To her great shame her tail was flagging high, leaving herself completely open, her pussy winking constantly, begging to be filled. And yet he still waited, content with hugging her close, rubbing her neck with his jaw. It wasn’t long before Luna couldn’t take it anymore.

To Tartarus with it; Luna threw her dignity away, the fire in her belly overpowering her rational mind. She grunted as she slipped away from the embrace, the Alpha unexpectedly letting her go without fuss, and she stood facing him, flank quivering. She bit her lips, hesitated for a few seconds, then she turned around, presenting her rear to the Alpha. Instead of leaping on top of her like she expected, he leaned in close, his hot breath washing over her burning marehood. Luna remained there, frozen in uncertainty, not quite sure if she was scared or eager for what came next. But yet again the Alpha took his time, the stallion inhaling her scent with an appreciative rumble, and after what felt like an eternity of waiting Luna whinnied impatiently.

“Oh for pony-sake, will you just take me already? What are you waiting f…”

Luna’s complaint died on her lips, her eyes going wide as the Alpha suddenly reared up, his powerful chest landing heavily on her croup. Her legs strained under his great weight, the stallion snorting dominantly as his hooves held her steady, his legs hooked around her foal-bearing-hips in a show of ownership. He then whinnied like before, deep and commanding, the message to the other stallions clear; Luna was his for as long as he wished, and they would have to wait for him to have his fill before they could enjoy her. With a beastly grunt he hauled his weight over Luna’s back, his hooves holding her sides tightly, and she felt his enormous stallionhood slap against her belly, leaving a trail of precum on her fur. Luna wanted to scream when she realized his flare was almost to her chest, there was no way he would fit inside her; the fire in her belly roared in disagreement.

She tried to slink away, reconsidering her choices in the face of his size, but the Alpha would not be denied, not when she had invited him to mount her so openly. Luna cried out in part surprise and part pain as the feral stallion bit down on her nape none too gently, keeping her in his control. He pulled her head back, his hips rolling as he angled his cock, and Luna had a perfect view of the moon as he gave his first thrust.

His stallionhood jerked up with expert precision, the large flared head ramming against her narrow slit on the first try, demanding entry. Luna whimpered in fear mixed with anticipation; his cock felt much too big to fit in her tight tunnel, but he didn’t seem to care. The Alpha snorted in frustration, his cock bending under the strain as he pressed his powerful hips forward, trying to sink inside. Luna’s arousal was now streaming from her stretched slit, dribbling around the stallion’s flared tip, running along the underside of his length before dripping from his overfilled balls. The copious lubrication helped him slowly push between her swollen folds, his whole body tensed with one sole purpose: spread his seed, put a foal in this strange mare… breed. Luna whimpered as she felt a quiver in her belly, an itch forming around her pussy, and she did her best to keep herself from winking; in vain. Her folds opened obscenely wide, welcoming the massive intruder inside.

The Alpha plunged into her with a loud *shlick*, her arousal bursting around his girth as he surged into her cunt, a throaty moan escaping from Luna’s lips. His length rammed its way deeper, his massive flare shoving her tender flesh aside, quickly reaching her depths. He bottomed out just as his thighs slapped against her shapely rear, the sound echoing around the barn, the noise of dozens of cocks slapping against bellies making it clear the surrounding stallions were enjoying the show. Luna’s eyes were wide in shock, her breath hitching as she felt his medial ring pressed against her pussy; she had somehow taken him to the hilt, his flare pressed snuggly against her deepest barrier. It was a perfect fit, at least in terms of length; girth wise he was stretching her walls to their limits. The Alpha snorted in satisfaction, his teeth still holding her nape, the stallion savoring her clenching insides for a few moments, before he started to pull back.

Luna openly moaned as his stallionhood slowly withdrew from her tight pussy, his flare scraping against her insides on the way out, the Alpha taking his time to make the pleasurable torture last. He was clearly skilled at pleasing mares, which was surprising considering the lack of any females around… Luna suddenly understood why there were only stallions in this barn, and why they all looked like they belonged in one of her sexiest stallions ever magazines. This was a breeding farm. Luna had barged her way into a breeding farm, and she was now surrounded by virile studs raised for only one thing: mating. In other words, she was utterly and properly screwed, in all meaning of the expression. The Alpha shuffled over her, his tip finally reaching her entrance, almost slipping out. His legs closed around her, holding her, his flanks quivering as he prepared for his next thrust.

And swiftly it came. The stallion pounded into her without restraint, his second thrust so powerful her hind hooves left the ground, her rear held aloft by his stallionhood alone. Stars danced in front of her eyes as his tip rammed against the entrance to her womb, the rounded tip spreading her cervix open, his full balls slapping against her thighs. This time he didn’t wait before quickly pulling out, and she barely had time to regret the emptiness inside her before a third thrust rocked her body, then a fourth, a fifth, Luna losing count as his hips became a blur.

The sounds of flesh slapping against flesh filled the barn, Luna getting jostled around like a ragdoll as the stallion pounded into her with wild abandon. She had a vacant expression on her muzzle, her eyes glazed over and mouth hanging open, a string of saliva hanging from her chin as she was fucked silly. The Alpha rammed his cock deep into her dripping cunt again and again, Luna’s frame shaking from the internal pounding, his flare like a battering ram against her poor womb. She could feel the fire in her belly clamoring to be doused, a ball of pleasure building deep inside her, ready to spring to life. She bit her lips, holding her climax at bay, letting it grow; the Alpha’s unrelenting pounding fueled her looming orgasm, his every thrust making her vision go white.

Luna didn’t know when she had started to rock her rear to meet his bestial humping, and she didn’t stop once she realized; she wanted more, she needed more! Navy blue fur met with black coat without a hint of restraint, his thrusts drumming a savage beat onto Luna’s rear. The Alpha rumbled in delight as his mate surrendered to his dominion, his teeth letting go of Luna’s nape; he knew she wouldn’t try to flee now. She was his. The Alpha threw his head back, ramming into her with new vigor, and Luna was overwhelmed by his feral intensity. It was too much… She was at her limit... No… She had just gone past it.

With a deep moan of ecstasy, Luna’s body tensed up, her wings quivering under the stallion, trying to shoot open. Her tight cunt clenched around his cock like a vice, the Alpha snorting eagerly as he strained to keep thrusting, the merciless animal intent on fucking her into blissful oblivion. Luna’s unfocused eyes rolled back and she gave a throaty whimper as her climax soared to new heights, her mind going blank with pleasure. She almost collapsed, her legs quivering, but the stallion on top of her held her close, his hooves keeping her from falling on her face. She let him rail her as he wished, too busy having the orgasm of her life.

The Alpha’s snorts were becoming short, his thrusts losing speed; his impressive endurance was nearing its end. The stallion took in a new rhythm, his hooves shuffling on the ground to change the angle of his thrusts. He no longer humped into her like a jackhammer, now his hips rammed into her with far more force than speed, his thighs impacting with her rear hard enough for her hind hooves to leave the ground, his cock withdrawing steadily before swiftly plunging back in. On the next powerful thrust, Luna felt his overfilled balls jump against her thighs; he was about to cum, there was no doubt about it. Luna bit her lips, anticipating the moment he would extinguish her heat with baited breath, before her mind caught up and finally realized her situation.

Here she was, in the midst of the most potent heat she had ever known, meaning she was at her most fertile time, and she was being plowed raw by a virile stallion… a stallion who was about to cum inside her. She had no condom to protect her, no contraceptive spell to keep her ovum from being swarmed by the Alpha’s sperm, and certainly no way to ask him to pull out. Her pupils shrank to pinpricks, finally realizing the real danger she had put herself under. She could feel his flare growing wider at this very moment, his cock growing alarmingly; she had to get him out of her!

Luna tried to appeal to her magic, but her horn sputtered and died. She tried to flap her wings, but the heavy stallion was on top of them. She tried to squirm away, and she squeaked as the Alpha bit down on her ear then pulled her back into him, his hooves digging into her ribs as he neared his end. In last resort Luna tried to beg, her words coming out in a jumble of nickers and squeals, her orgasm still choking her throat; she was too late anyway.

With a loud victorious whinny, the Alpha released her ear and rammed his hips into her reddened rear one last time. He ground himself as deep as he could, his flare stretching her insides to the limit, his tip pressed tightly against the entrance of her womb. Luna looked at the moon, praying for a miracle, her pussy still clenching around his length… Then his whole shaft suddenly jerked, her whole body jumping with it, and she knew she was doomed. She felt his cock swell, a large surge travelling from the base to his tip, his flare holding her cervix open. She gave one last whimper, the Alpha responding with a grunt, and his cock positively erupted, semen shooting from his tip like a hose.

The gush of seed sprayed directly into Luna's womb, making her whole body quiver in delight and terror; the heavy cum flowed from his throbbing cock endlessly, the long drawn out ejaculation packing her full with his semen. Once again the Alpha whinnied atop her, his balls emptying his virile seed into her fertile womb, staking his claim on her royal body. He kept cumming and cumming, his cock spasming endlessly; he could probably inseminate a dozen mares in a row, but since Luna was the only female around, she had the honor of receiving his full load. Luna’s mind was in total chaos, her lingering orgasm making it hard to think; the warmth in her womb made her shiver at the implications, there was enough stallion cream in her to impregnate a mare three times over. And still he came, the Alpha’s lumpy semen starting to leak around his cock, dripping down her thighs, her womb unable to contain it all.

After what felt like an eternity, the Alpha’s release finally started to taper out. His cock started to soften, his length throbbing lazily as he pushed his last few spurts into her overstuffed cunt. He dismounted carefully, his limp stallionhood slipping from her abused pussy with a gush of thick semen, the stuff slowly oozing from her gaping slit, falling with soft *plaps* into the straw bedding. Luna’s legs were trembling, barely able to keep herself standing, and it took all her resolve to keep from collapsing on the soft ground. The Alpha circled around her, the stallion cocking his head to the side as he watched Luna pant for breath. He leaned closer, Luna gritting her teeth as she prepared to bite his muzzle -or kiss him, she wasn’t sure- but the beast just sniffed her, his nostrils flaring wide. He kept at it for a few moments, then he snorted, his ears perking up, and he leaned back, a soft nicker rumbling from his throat. Luna blinked, confused; why was he looking so proud of himself all of a sudden? The fire in her belly had been completely extinguished thankfully, so it made it easier to think, but before she could think too much about his smug expression, the Alpha gave her one last look, then turned away.

She watched the great beast saunter away, her eyes naturally drawn to his swaying limp cock, trickles of seed still leaking from his tip. The ring of onlooking stallions parted before him before closing back, hiding him from view, the stallions watching her greedily. Luna blinked, she had almost forgotten about them; now that the fog in her mind had lifted, and the fire in her belly was strangely absent, it was easier to think. Since the Alpha had declared her as his, she could probably escape now; she had a small window to cast her contraception spell, but she still had time to ensure she wasn’t knocked up. Probably. Luna prepared to spread her wings, but a loud whinny made her freeze in place: she recognized the Alpha’s voice, and she had half a second to wonder what he had just said before the ring of stallions closed in on her. She only had time to squeal in fright before she was swallowed in the mass of soft fuzzy coats and hard stallionhoods.

Luna was prodded from all sides, cocks absolutely everywhere, the flurry of legs somehow avoiding trampling her. She recoiled from the sounds of furious fighting overhead, the stallions clashing against one another to have the honor of taking her next, their desperate need leaking from their tips. Luna tried to crawl away, but only got slapped in the face by a girthy cock in the process. She managed to get to her hooves, but as soon as she was standing one of the stallions reared back and straddled her rear. Luna tried to shake him off, tried to keep him from mounting her, but with so many bodies pressing against her there was little she could do. His tip rubbed against her inner thigh, pushed into her rear, and he found his mark in the next thrust.

The stallion whinnied in relief as his shaft slipped into her oozing cunt, and in the next instant he was thrusting away, the other studs giving them some space begrudgingly. He was smaller than the Alpha, but he was still much bigger than any pony stallion Luna had ever been with; it was a tight fit, but the stallion pounded into her without care. There was no sense of rhythm this time, he fucked her like the animal he was, his cock plunging into her cum-stuffed cunt messily.

Luna was taken by surprise when the stallion started to cum just a few moments later, his cock jerking in tandem with the bursts of spunk inundating her pussy, his semen mixing with the remnants of the Alpha’s seed. Luna whimpered in despair as her fertile womb was bathed in a new surge of thick baby batter, the horse humping into her to milk his release to the end, probably hoping she would bear his foal over the Alpha’s. He rumbled in satisfaction, his muzzle pressing against her neck, and his cock was soon slithering from her oozing pussy, limp enough for him to dismount. As soon as he was off her back however, a new weight landed on her, Luna huffing as her legs buckled tiredly.

This new stallion was a lot less careful than the previous, his errant thrusts completely off the mark. Luna winced as his cock battered her thighs and belly, his length quickly getting covered in a mix of spunk and female juices. He whinnied pathetically, his hips humping haphazardly; after a few more tries he managed to find Luna’s entrance, and he slammed inside with a loud nicker. He came with just one thrust, but what he lacked in endurance he made up in productivity: the stallion came long and hard, his seed flooding her stuffed womb. Soon enough Luna was overflowing with his semen, but he kept shooting his load deep inside, each burst pushing a spray of horse spunk from Luna’s pussy.

He was still cumming when a third stallion grew impatient, the Arabian shoving his brethren off Luna’s back. The stallion whinnied in displeasure, his erect cock springing from Luna’s pussy with a burst of seed; ropes of heavy semen landed on her rear, covering her cutie mark, but she didn’t have time to complain about the mess before she was being mounted once more. This one was huge! Almost as big as the Alpha, and a lot less caring for her pleasure; the well endowed stud rammed his enormous cock inside with brutal intensity, a spray of mixed spunk erupting around his girth. The new stallion quickly built up his release, and she was filled with his own brand of thick splooge just moments after. Luna could only moan helplessly as he dismounted with a happy nicker, a new horsecock instantly plugging her overflowing hole.

The cycle continued endlessly, Luna getting no rest as she was fucked into a stupor: a stallion mounted her, he came after a few thrusts, he climbed down, only for a new stallion to take his place. A few of them kept thrusting longer, others came instantly, Luna lost count of how many cocks had defiled her royal pussy; and she wasn’t halfway through the herd yet. The most impatient didn’t even wait to find her marehood before cumming; they either came while hotdogging her plump rear, painting her back with their seed, or they would press against her sides and belly while another was riding her, shooting their loads all over her. Maybe they realized that Luna was most probably already knocked up at this point, Luna’s womb bloated with the mixed spunk of dozens on stallions, there was no way her poor egg had not been swarmed into submission at this point. And they were still so numerous around her, waiting their turn with her; she knew she would be mounted by each and every one of them.

By the time she had gone through most of the herd, Luna was covered in streaks of thick cum, her pussy constantly gushing with the loads of the previous stallions, her eyes bleary and unfocused. She had lost count of how many stallions she had serviced, and how many times she had came while being ridden and filled like a whore. It was clear the studs had chosen her as their personal broodmare, a female to dump all of their accumulated seed and frustrations, after being denied release for Equestria knew how long. Her place in the herd was clear: she was but a breeding bitch in their eyes, they would put foal after foal in her belly, using her tight pussy whenever they felt the urge, until she sired a new generation of broodmares for them to breed. Then Luna and her daughters would be lined up and railed into submission, her own sons watching their mother and sisters being impregnated, just waiting for their turn, the queue getting longer with every passing year... Oh goddess this was so wrong, but it only made her cum harder! Luna was panting in exhaustion when the current stallion finished filling her with a new helping of cum, and she stumbled on the ground drunkenly when he dismounted.

She laid on her side, her sides raising as she tried to regain her breath, the smell of sex saturating the barn, semen clinging to every surface of her body. Her ethereal tail and mane hung limply against her stained coat, saturated with stallion seed. She heard shuffling nearby, and with extreme effort she managed to look around. The herd had dispersed, the Arabians milling around the holding pen calmly, their limp cocks making it clear they had all used her at some point; she felt a strange burst of pride when she saw just how many studs she had pleased. Luna’s gaze was drawn to the last stallion waiting for a chance to take her, his hooves shuffling on the straw almost shyly.

It was the young Arabian, the one who had tried to mount her first; he had been left for last, his youth making it hard for him to fight off the older stallions. He was giving Luna a pathetic pleading look, soft whimpering escaping his lips as his cock slapped on her belly. The alicorn blinked sleepily, then huffed wearily; she had gone this far, what would one more hurt anyway? Slowly she got to her hooves, struggling with her fading strength. The young stallion didn’t wait for her to be ready and she almost fell when he reared back to mount her, her wobbly legs barely able to take his added weight.

Like before, he was quite eager but didn’t have much luck with his aim. Luna looked at him over her shoulder, wondering if she was his first mare. From the look of utter frustration and despair on his muzzle, it seemed she was; he was even starting to go soft, poor thing. Luna sighed, then her horn shone softly. The young stallion paused in his awkward humping, fascinated by her magic, then he gave a surprised nicker when Luna gently took hold of his cock in her telekinesis, her aura rippling over his length and his balls. Luna tsked as she handled the softening stallionhood, her magic pumping it back to full mast in a few instants. She gently squeezed his balls, noting that they were quite smaller than his elders, but they still held a prodigious amount of seed. The young stallion nickered, his hips resuming their desperate humping, and Luna brought his thrusting length to her oozing entrance.

He inhaled sharply when he slipped inside, her battered cunt squeezing him lightly, her walls stretched by the hours of constant pounding; he didn’t seem to mind her loosened state however. He started to thrust into her with gusto, his aim still a little off, his cock threatening to slip out everytime he withdrew. Luna tsked softly, her magic fondling his balls to try and stir him into position, her magic holding him back from thrusting himself into an early finish. She angled her shapely rear, positioned his hooves around her wide hips, tutting when he did something wrong. The young stallion obediently followed her instructions, and soon enough he was hilting into her like a stallion should, his balls slapping against her rear. He was quite happy with himself, so happy in fact that he rammed into her particularly hard, and Luna’s front legs collapsed under her.

Luna barely managed to keep her hind legs upright, her rear sticking out as the young stallion clung to it, still pounding into her desperately. Luna shook her head, a little amused, when a shadow fell over her. It was the Alpha, he had approached while Luna was instructing the younger horse, and he was now standing over Luna’s prone form. He was looking at Luna’s shining horn curiously, even bringing his snout next to her horn to give it a sniff. He then leaned back, then looked at her expectantly. Luna blinked sleepily, not knowing what he wanted, until he stepped over her and she had his limp stallionhood bobbing next her muzzle. The request was obvious.

Luna obediently took hold of the Alpha’s soft member in her aura, her magic running over the great length with amazement; she had managed to take the whole thing earlier, she still didn’t know how. Luna gently weighted his balls, biting her lips when she felt just how heavy they still were, much bigger than the young stallion currently railing her. Luna fondled his balls, pumped on his twitching stallionhood, and after a moment’s hesitation she took the tip into her mouth. The Alpha grunted in appreciation, his hooves kicking at the soft straw bedding as he received a royal blowjob from the alicorn. Luna’s tongue ran over his soft flare, suckling on the remnants of his seed, moaning eagerly; she could taste her own arousal clinging to his shaft. She sucked on his cock while the stallion behind her reached a fevered pitch, his thrusts rocking her body; she used the momentum to bob her head on the Alpha’s stallionhood, taking more and more into her muzzle.

The young stallion gave a strange strangled whinny as he came, his length throbbing as he unloaded for the first time into a mare, making sure to grind his hips as deeply as possible to get all of his seed into Luna’s womb. She found the idea of this inexperienced colt managing to impregnate her over all the other burly males to be ridiculous, but still, it was cute how desperately he tried. The colt shot the last of his load with a happy whinny, then remained perched on top of her, his softening cock trapped inside Luna, his hips humping weakly as if trying to get hard again.

Luna didn’t mind his antics, too preoccupied with the growing stallionhood in her mouth. The Alpha was slowly becoming erect once more, and she could feel his balls churning to produce more seed in her magical grasp. She slathered his cock with expert licks, moaning when she was rewarded with a few drops of precum, but before she could coax anymore from him he stepped back, his flare popping out of her mouth. The Alpha then circled around her, shouldered the young stallion off of Luna -the poor colt whinnied in protest, his limp shaft flopping out- then he quickly mounted her raised behind, his hooves landing on either side of her. His half-erect length plunged inside smoothly, Luna's pussy eagerly squeezing him, drawing him deeper, welcoming him home.

This time he didn’t try to be subtle, he just humped into her with reckless abandon, his cock growing to full mast between each pounding. Luna had a silly little smile on her lips, her eyes rolling back as she was taken by the stallion who had conquered her. He really was the best out of the whole herd; she could say this without a doubt, since she had been taken by the lot of them. No other reached quite so deep, no other stretched her quite so much; and no other was more deserving of being the father to her foals. She idly wondered if she could bring him back to Equestria to be her… personal pet. She would walk him around in a leash, then, when no one was looking, she would be the one wearing a bridle, and he would hold her reins as he stuffed her full of his potent seed. They would mate like animals in the gardens, in the bathhouse, her room would reek of semen like an insemination shack... Luna's musings quickly devolved into mindless moaning as he picked up the pace.

It didn’t take long for him to slam his hips into Luna’s buttocks, his flare bursting to life as he fired his second load of the day, his production as impressive as the first time. Luna’s legs quivered as she was filled up by her mate, her stallion, his thick seed overflowing and pushing all the other mixed semen out of her pussy, the Alpha not satisfied until she was properly his once more. He remained still, letting Luna’s clenching cunt milk him dry, strong bursts of seed surging into his broodmare without end. By the time he started to withdraw, his seed was overflowing around his length, not a drop of another stallion’s cum left in her, and he made sure to pack more into Luna as he exited her battered pussy.

Satisfied, the Alpha pulled out, his cock still hard, and he slid his length over Luna’s rump, still cumming like a firehose; she was painted with his seed, the thick stuff clinging to her fur, his scent overpowering the other stallion's; he was marking her as his territory, and she loved it. As soon as he started to go soft, the big Stallion stepped away, leaning down to give Luna a quick nuzzle; the gesture would have been sweet if he had not been pounding without restraint just moments before. He then strutted to a corner of the pen, his big black cock swaying like a pendulum. The groggy alicorn groaned as she slowly got to her hooves, her legs trembling under her, pussy oozing with the Alpha’s seed; okay, she had had enough for today.

She stumbled her way to the edge of the pen, the herd paying her no mind, though she did have to slap the young stallion with her damp tail as he kept trying to mount her; while his antics were cute at first, she was quite satisfied already. He tried to immobilize her by hugging her neck, and was quite surprised when the alicorn just kept walking without slowing despite his weight and her apparent exhaustion, his hooves grinding against the straw helplessly. Luna rolled her eyes, and with a simple swing of her hips he was shoved away like he weighted nothing. She slipped under the bars, the stallions suddenly neighing in distress as their new toy escaped, but Luna paid them no mind. She looked around for anything she could use to clean herself, and quickly found just what she needed; a large hose meant to clean the horses, it even had a hot water knob! She quickly washed the layers of cum off her coat; the scent would cling to her fur for some time still, but at least she didn’t look like she had fallen in a vat of glue.

Sighing in contentment, Luna gave the herd one last look, the stallions crowding around the pen’s barrier, calling to her desperately, afraid of losing their new playmate. But Luna only had eyes for one stallion, and she found him standing on the other side of the pen, the Alpha looking quite calm in contrast to his desperate underlings. He saw her looking over, and he snorted, giving her a cocky look that screamed “I know you’ll be back”. And he was right. Luna watched the beast lie down for a much deserved rest, ignoring her, and she whispered under her breath.

“I’ll be back to collect thou later, my little stud.”

With that she spread her wings, then soared through the loft doors.

Epilogue: Like Sisters

View Online

Dawn was just starting to peak over the horizon when Luna exited the barn, her flight not very graceful considering she looked like a drowned cat, and her wings were a feathery mess. She landed on the patio between the two barns, gave the building housing her stud a wistful look; she would have to prepare a special chariot to bring the Alpha back to Equestria, and she’d need to spin some excuse for doing so. She shuddered, thinking about his large form draped over her back, then prepared to depart. She froze in alarm when she heard a door creaking open, and her head whipped towards the sound; it was the other barn’s door, it was slowly opening, she was about to get busted by a human! She was rooted in place by fear, her wings fluttering uselessly at her side; The door slowly swung open, and out came… Celestia.

“What in the blazes?” Luna said, dumbfounded.

Celestia’s ear flicked at her words, and the alicorn froze in the middle of closing the barn door. The two sisters stared at each other, their eyes roaming over their respective bodies. Celestia was quick to realize how disheveled her little sister looked, her feathers out of place, her fur soaked like she had just stepped out of the shower. And Luna would have to be blind not to see the way Celestia winced as she rolled her weight, as if her hips were aching, how her coat was in disarray as if she had been licked all over, how her crown was askew on her head... Oh, and also the enormous pink stallionhood limply hanging under her, the various fluids attached to it leaving no doubt that it had been used recently. Luna’s ear twitched as she heard a soft nicker coming from inside the barn Celestia has just exited; it sounded like a mare, actually it sounded like there were a lot of mares inside. And they all sounded quite… pleased.

Luna fixed a deadpan look at her hermaphrodite sister. “Really?” She asked, incredulous. “Hath thou no shame Sister?”

Celestia blushed deeply, her cheeks puffing out childishly. “Well what did you expect me to do? I couldn’t just bed Equestrian mares and risk foaling heirs; it would be chaos!” She hissed, approaching her sister, her cock swinging from side to side, dripping mixed fluids on the ground. “I was going crazy with that scent of yours, I needed to blow off some steam before I started courting the maids; do you have any idea how mortifying it is to be aroused by your own sister? Uh?”

“Not as mortifying as mating with a cohort of mindless mares, t’would seem.” Luna’s eyebrows rose.

“Oh please.” Celestia snorted, jabbing her little sister in the chest. “Like you weren’t having fun with the stallions on the other side.”

“I do not know what thou mean.” Luna replied, blushing softly. Her blush turned into a cringe when Celestia’s magic took hold of her mane, displaying a long streak of creamy white in her starry mane.

“You missed a spot.” Celestia deadpanned.

“I was overpowered!” Luna defended. “The wicked animals took me by surprise! I could only go along while they sated their bestial needs!”

Celestia blinked, before she leaned forward, her nose almost touching her sister’s. “You were… overpowered?” Luna tried to shy away, but Celestia followed. “You, an alicorn capable of lifting a boulder without breaking a sweat… were overpowered. By horses.”

“They are quite formidable animals….”

“Oh please,” Celestia blew a raspberry “you’re strong enough to punch a mountain if you wanted to, not to mention your magic. Actually, I’ve seen you punch a mountain, and you won!”

“Twas eons ago…” Luna babbled, crossing her hooves awkwardly. “I’m not as strong as I once was…”

“Oh spare me.” Celestia shook her head, taking a step back. “You just like being dominated and you know it.”

“Why I never!”

“You do!”

“I do not!”

“You do too!”

“I do not, and please put your… thing, away, tis unseemly!” Luna grunted, pointing at her sister’s cock. She was quite displeased to note that Celestia was bigger than her new stud; she wondered if it would even fit inside her. As soon as the thought crossed her mind her brain started screaming and doused itself in oil, looking for a match. She winced, nauseated, her traitorous subconscious throwing awful, awful ideas at her. “Ew…”

Celestia blushed as she realized her stallionhood was still on full display, and she quickly applied the spell that kept it hidden at all times. She then paused, sniffed the air carefully, then did it again. She blinked, her mouth opening and closing, before she finally asked her question.

“Luna… did… did you take… Ahm… precautions, before throwing yourself at the breeding studs in that barn?”

Luna grumbled, still disgusted with herself as incestuous images flashed in her mind. She pushed all of them in a deep recess of her mind, never to be opened again, before she answered truthfully. “No, it’s not like they could impregnate me anyway, we are different species.” Luna paused, looking at her sister curiously. “Why?”

“Well, I thought so too but…” Celestia gulped heavily. “You don’t… you don’t smell like you’re in heat anymore.”

Silence fell between the two sisters, the alicorns sharing horrified glances as the implications set in.

“Sister?” Luna began, already knowing the answer. “Did you… take precautions yourself?”

“… No.”

“… How many…”

“Dozens.” Celestia cut in, sweat dribbling down her brow. “They kept asking for more… they were so needy… all in heat…”

“Oh sweet goddess…” Luna swore. She suddenly had a vision of a hundred little Celestias running around the castle, giggling cutely as they devoured every cake in sight, all screaming “aunty Luna!” as they swarmed her with hugs and kisses, her blue hoof sticking out in a plea for help as she was swallowed by the white tide; it was a vision of horror, a vision of doom... Hopefully it wasn’t a prophetic one; the Royal Sisters were known for having those occasionally…

“Wait, this doesn’t mean anything!” Celestia rushed to say, a flicker of hope in her gaze. “Maybe your heat is just abated because you’ve been… hmmm… filled, for lack of a better word.” Celestia and Luna winced, but the Solar Princess soldiered on. “It most probably didn’t take, and your heat will return in a few hours!”

“And if it doesn’t?” Luna whispered, feeling the Alpha’s heavy seed swirl around inside her, still trapped in her womb.

“We’ll cross that bridge when we come to it.” Celestia said resolutely. “I’m sure it will be fine, and we can always come back if we need to… take our responsibilities.” Celestia gulped, her gaze briefly flickering to the broodmare stable; her broodmare stable. “Now come, before any human spots us. I’m already late for Equestria’s sunrise!”

Celestia hurriedly flew into the morning sky, leaving a perplexed Luna behind. She had used the idea of being bred by the stallions to fuel her fantasy, thinking all along they couldn’t impregnate her, and now it turned out it might become a reality. This would greatly complicate things if it was true. She gave the stallion barn one last look, then followed the retreating form of her sister.

No matter how things turned out, she knew she would be back here, sooner or later. Her stud was waiting for her.

Bonus chapter: The Other Barn

View Online

Four days. It had only been four days, but it felt like years had gone by as far as Celestia was concerned. Luna's heat had come like a sudden storm, rampaging through the castle, leaving a wake of destruction in its wake... To make things worse the situation would not get better for a few more days still, when Luna's cycle was scheduled to end; if it ever did end. Considering the strength of her scent, this was no common heat, it could very well just last until Luna had enough and just decided to... let nature take its course. Celestia shuddered, revolting thoughts about her sister dancing in her mind; she had never felt so awkward in her life, and it had all started with the incident four days ago.

The memory of that dreadful evening would be etched into her mind forever. She could see herself, eating her dinner serenely, the picture of a prim and proper Princess, her royal guards standing with perfect discipline around the dining room. And like every evening Luna had barged through the doors with little ceremony, uncaring for appearances; as always she was quite disheveled after her ‘morning’ shower, having yet to go through her session of royal pampering at the hooves of her maids. Her face was scrunched up with sleep, the poor filly unable to think clearly before she had her coffee; pure, black, unsweetened coffee. How Luna could drink such a foul and sour tasting beverage Celestia couldn’t fathom, even with cream and an avalanche of sugar she found it repugnant.

Celestia had smiled innocently, wondering how she would annoy her little sister today, but as soon as she opened her mouth she had smelled it; she had smelled her. Celestia recoiled in surprise but the scent had already invaded her senses, the heated perfume saturating her every breath; she could practically taste it, so strong was Luna’s heat. The smell was so powerful it felt like she had been slapped in the face, Luna's body radiating waves of concentrated pheromones; Luna might as well have been waving a flag with Fuck me please! written on it. Celestia's cheeks had started to burn quite fiercely, dazed by the blow momentarily, completely taken off guard. By the time she had regained her senses, Luna had taken her seat across from her, so close, too close, and the inevitable occurred: her stallionhood began to swell in her invisible sheath, slithering free like a big pink snake. It was her body’s natural response to the desperate calls of a mare in need of a good rutting, even if that mare was her sister; the thought alone was disgusting! Celestia had stuffed her hooves under the table, trying to push her erection back inside, but there was nothing she could do against the overwhelming scent, her breeding instincts running wild.

She hadn't been alone in her struggles. All around the room her Solar Guards panted like dogs, their hooves shuffling awkwardly to try and hide their massive hard-ons from their princesses; not an easy feat for the burly and virile stallions. And none of them had a problem quite as big as Celestia’s. The alicorn had squirmed in her seat as her cock had risen to full mast, coaxed by her sister’s heated scent, and she had to hold it back from bumping into the table with both her hooves. It was mortifying, and it only got worse when Luna saw her squirming; Celestia had avoided her sister's gaze, still holding to her cock, then she had pointed to her guards in a way of explanation. It seemed the silly filly had not even realized she was in heat. Luna’s muzzle looked quite cute when she was flustered, and Celestia would have enjoyed the sight if she hadn't been fighting the impulse to stuff her cock into Luna's open mouth, make her sister's blushing cheeks bulge out with her flesh.

The next few hours had been much too embarrassing to remember, though she did recall vividly how much she had suffered while giving her sister a bath. The scent of soap and the clothespin on her nose had done nothing to save her from Luna’s scent; she had bathed a red-faced Luna with her invisible stallionhood at full mast. Her instincts had demanded she mount her own little sister, the stallion in her wanted nothing more than to fill Luna with her seed, put a foal in her belly... Celestia had never been so ashamed of herself. They weren’t animals for pony sake, she couldn’t let her instincts rule her! The bath had mercifully ended soon enough, Luna scurrying to hide in her room, while Celestia had remained behind to take her own shower, or so she had said. Instead she had masturbated under the hot water stream desperately, like a horny teenage colt, lewd thoughts of her sister fueling Celestia's lust. By the time she was done the drain was clogged with her thick semen, the abundant white goop pooling around her hooves. If even one drop had gotten into Luna...

Afraid she would lose control, Celestia had avoided Luna as much as possible since then, but there was no escape for her; Luna’s scent was everywhere in the castle, even after the Lunar Princess locked herself in her room. Celestia still had to endure the inviting scent, the cloud of pheromones calling to her, her cock permanently hard and desperate for release. Strangely enough other ponies didn’t seem to be affected after Luna quarantined herself, Celestia’s senses apparently much sharper than her guards… or perhaps Luna’s heat called for a partner of her own caliber, a stallion worthy of an alicorn; the scent called to her specifically. Celestia had to relieve herself dozens of times each day, sometimes even during court, and before long she had begun to ogle the curvy flanks of her maids as they walked past. Why were they all so sexy and why had she ever thought that enforcing a french maid uniform was a good idea? It was when she had caught herself seriously thinking about inviting one -or two- of the servant mares back to her room that she knew she needed to get away.

*******************

The human world was quite lovely, when you looked past the omnipresent concrete shell. Celestia hovered over Canterlot, the Human version that is, taking big gulps of fresh air as she watched the sun slowly disappear over the horizon. The air smelled of pollution and asphalt, but at least she could breath without going into a mating frenzy; she didn't even have an erection! It was strange to see the sun lay to rest without her help, like she had done over in Equestria but moments ago; it was quite relaxing actually, to sit back and enjoy the spectacle. Even if it was a little slow to her liking.

The red and gold sky reminded Celestia of another Sunset entirely, and her gaze wavered as she looked towards a particular house, near the edge of town. She could feel her, she could feel her little Sunset’s aura, her little Shimmy all grown up, so close yet so far away. Celestia had half a mind to fly to Sunset Shimmer’s home and ring the doorbell, just to hear her voice again, maybe embrace the stubborn girl if Sunset didn’t slam the door closed at the sight of her. But now was not the time; Sunset would come home when she felt ready, even if it meant Celestia had to wait a few more years. She wouldn’t wait much more than that though.

Celestia turned away from her Sunset, and she flew aimlessly towards the rising moon, lost in memories of a simpler time. She glided more than she flew, using thermal winds to stay near the clouds, and she was startled from her reverie when she found herself passing over fields and quaint little groves of tree instead of concrete pavement. She had to squint to see through the darkness, her eyesight very poor at night, but she was giddy to see some of those weird machines the humans used to farm, their glossy exterior shining in the moonlight. They looked like giant pieces of candy lost amongst the fields; she had half a mind to land and give one of them a lick, to see if the red machine tasted like cherry. It was a silly thought, but it made Celestia chuckle happily nonetheless.

Celestia’s ear flicked, a sound catching her attention; it almost sounded like a pony whinnying. Confused, she turned and followed the muted sounds, until she was gliding over a peculiar looking farm, with two large buildings surrounded by pastures; she made sure there were no humans before landing. She lazily floated down like a leaf, banking left and right to avoid the rising thermal winds, and her hooves touched down between the two stables, light as a feather. She tilted her head, listening to the soft nickering, her ears perked up in wonder. The two buildings were very similar, but something was drawing her to the largest of the two, and she approached with silent steps. Once she was close enough, she pressed her ear to the door, then tried to open it.

The door was locked, but it was no issue for her. With a burst of magic the latch popped free, the unlocking spell child’s play for Celestia, and the alicorn slipped into the barn without a sound, closing the door behind her. The inside was dark and gloomy, but Celestia quickly remedied the situation: five flashes of her horn later, and the stable was illuminated by five spheres of magic, not too bright to avoid attracting attention, but enough that she could see the farther walls as she spread them out. Celestia blinked, her mouth falling open.

Horses. Earth horses, all looking back at her with curious wide eyes, a herd of Equines the likes Celestia had never seen. The large herd was penned-in by steel barriers -thought Celestia didn’t understand why they couldn’t just crawl under them- they seemed to have more than enough space and the ground was covered in soft straw to lie on comfortable; all in all they seemed to be well cared for. Celestia cooed in amazement as she approached the barrier, eyeing the animals with wonder. They were all so pretty! Tall, almost as tall as her actually, their shiny coats black as the night, with long matching manes… Oh, and they were all mares if Celestia wasn’t mistaken, they certainly had the right curves. She had to get a closer look!

With a graceful flap of her wings, Celestia soared over the barrier and landed on the straw bedding, the closest horses skittering away shyly. Oh but they were beautiful! So graceful, their legs long and slim, with shapely rumps and slender muzzles, just like the pretty Saddle Arabian Princess who had visited Canterlot not long ago; now that was somepony Celestia wouldn’t have minded taking to her room, practice some old fashioned politics under the covers! Celestia chuckled, stepping closer to the herd with a gentle reassuring smile, the horses watching her approach, more curious than scared now. There was even one of them coming closer; she was the tallest of them all, with a wide shapely behind that made Celestia's mouth water, her swaying foal-bearing hips hypnotizing. It was like seeing one of those old fertility goddesses statuettes come to life, not even the curviest of Equestrian mares could hope to match, expect maybe Celestia herself. But why was she turning around… HOOVES!

Celestia deftly ducked under the violent two-hooved buck, black hind-legs whipping above her head, kicking a hole through her ethereal mane. The beautiful mare twirled on her hooves, the animal snorting angrily, annoyed her surprise kick had failed. Celestia fluttered to the side, giving the mare an affronted glare; who greeted strangers with kicks to the face? Well, who besides the yaks. The mare shook her head, clearly not done with her, and she charged. Celestia rolled her eyes as she just sidestepped gracefully, the mare thundering past her; she even took the time to admire her toned flanks as she ran by. The alicorn leaned away with a deadpan expression as the mare’s hooves kicked out once again, and they were facing each other in the next instant.

“Now what has gotten into you, my little pon… horsey? No, that doesn't sound right…” Celestia mulled it over, ignoring the death glare the panting mare was giving her. “My little mare… yes, that’s better.” Celestia put on a disappointed pout and looked down at the angry animal. “Now what has gotten into you, my little mare, why do you attack me so?”

The horse neighed back at her, and despite the lack of words Celestia had no issues understanding her meaning; put them up partner. The horse then reared back, displaying her strength, the other mares around recoiling in fear; it was like she was asserting her rule. Celestia then understood: she was the head mare, the leader of the herd. In the wild she would rule over the herd of mares, only accepting males into her group when she needed them for breeding purposes, before kicking them out when they were done. Celestia knew all this because ponies used to have similar ways… a couple million years ago, before the advent of magic and tools; this was like watching archaeological findings come to life! She guessed the Head Mare felt threatened in her role with the appearance of a taller, stronger female, and she needed to fight back. Celestia shook her head, amused: there was no need to fight really.

The mare had no chance against her.

The Head Mare charged, her hooves digging into the straw, her eyes burning with fury… and she suddenly stopped dead in her tracks. The mare looked around, confused, her legs still kicking under her as she ran in the midair, her body suspended in a cloud of golden magic. Celestia just tutted like a mother scolding a child, still gently holding the Head Mare aloft in her magic; she was a little heavy, but with her power she barely felt the weight.

“That’s quite enough, my little mare.” Celestia smiled, trying to appease the panicking animal. “Don’t worry, I would never harm you.” She caressed the mare’s cheek, looking at her chiseled muzzle from her profile. “Hmm, you are very pretty, you know that?” She carefully settled the Head Mare back down, her magic giving the startled animal a reassuring pat on the head. “If you weren’t just an animal you would undoubtedly become a model back in Equestria.” She reached under her wing, producing a shiny apple she had taken as a snack. “Here, if you behave I’ll give you this apple, there’s a good girl!”

The Head Mare was trembling, clearly realizing she was woefully outmatched, her eyes flicking from Celestia’s smiling muzzle, to the shiny red apple, and back again. She hesitated, took a step back, froze when Celestia tutted at her, then she finally gave up and approached the superior mare with her head lowered in surrender. She carefully took a bite, eating out of Celestia's hoof; her eyes widened when the juicy sweetness filled her mouth, and she quickly gobbled down the rest, uncaring she was being humiliated by her rival.

“Hmm, yes, I would react the same if it was the first time I was eating an apple from Sweet Apple Acres.” Celestia smiled gently, scratching the Head Mare’s jaw. The animal recoiled from her hoof, her eyes still full of resentment. “Oh don’t be like that,” Celestia sighed good naturally, “I’ll be off in a bit and you’ll be back to being on top, I swear.”

The Head Mare snorted, apparently unconvinced, and she turned away to go skulk in a corner; her rear was quite lovely form this angle, when she wasn't trying to kick Celestia's head off. As soon as the angry mare was out of reach, Celestia found herself surrounded by the other mares. They sniffed her curiously, all of them quite eager to greet their new -if temporary- leader, and Celestia responded with gentle coos, her muzzle rubbing against theirs in greeting. These horses were so very cute! What they lacked in intelligence they made up in friendliness. No wonder the humans took them as pets, Celestia almost wanted to take one back home; she would leave a few sacks of gemstones as payment, Twilight had said humans were quite fond of them. She could dress it up and play pranks on the castle staff, watch them try to deal with a guest that acted like an animal... because it was one! Oh she couldn’t wait to see Luna’s face!

The thought of her sister sent a thrill of excitement down her spine, her mind recalling the heated smell she had left behind in Canterlot. Celestia sighed when her shaft stirred to life in her sheath, starting to emerge; it had been nice to be able to walk around without her cock swinging around under her, but it seemed that even the memory of Luna’s scent was enough to set her off now. With a sigh she looked under her, a quick burst of her horn revealing her stallionhood slipping out of her sheath, a fine coating of old precum clinging to the veiny surface. Celestia glared at her cock like she was trying to scold it, before she sighed and leaned back up, closing her eyes in aggravation.

“I’m so sorry ladies,” she said, addressing the surrounding mares. They couldn’t understand her, but it was the thought that counted. “but I will have to depart to take care of my…” She shook her hips, making her limp cock jiggle merrily, “little problem.” It was liberating to be able to let her male parts swing about so freely with others watching, it made Celestia quite giddy; and just a little bit aroused. She opened her eyes, smiling her peaceful smile. “You have been a charming… audience…” Celestia gulped, only now seeing the effect her stallionhood was having.

The mares were all staring at her cock like it was a succulent piece of cake, all of them standing still as they stared unabashedly. Celestia felt a little self-conscious now, not understanding their reaction; they were just animals, right? Having a male strut around with his package out must have been a common sight… Oh wait. Celestia looked around, gulping loudly as she remembered a little fact. There were no males around… they were all mares… and from their hungry stares it was obvious they were all very horny. Their nostrils were flaring with every breath, and with a pang of embrassement Celestia realized her cock must have been stinking from her last masturbation session; she hadn't thought of washing it. And now a whole herd of pretty mares were sniffing her shameful scent, their tails swishing behind them, all of them looking at her growing cock with hunger, as if they were... Wait… Separating the females from the males… The other barn… The instruments she could see lining the far wall… The mares all looking like perfect specimens of femininity... Was this… Had she just blundered into a… into a breeding farm? Uh oh…

“Hmm, well this was lovely, but I have to go now.” Celestia babbled, taking a few steps back, her cock bobbing under her as she did so; the mares all followed her stallionhood’s movements avidly. “I’m sure you will all be given lovely stallions to play with, once you go… into… heat… oh Goddess no…”

All the mares, every single one of them, were now raising their tails, a very familiar scent reaching Celestia’s sensitive nose. The scent of a whole herd of mares in heat assaulted Celestia’s mind; individually It wasn’t as strong as Luna’s, but when it came from dozens of mares at once... It was enough to drive a stallion insane. Celestia swiftly covered her nose with her leg, but the damage was done: her cock had gone from limp to completely hard in a single heartbeat, her member beating against her chest with anticipation. The mares all nickered excitedly, clearly impressed with her size, and a few of them started to turn around, Celestia could now get a glimpse of their oozing private parts… NOPE!

Celestia tore her eyes away from the enticing view, her cock slapping against her chest in protest, but she had seen enough; the mares were beautiful, true, they had the physic of Equestrian supermodels coupled with a dash of exotic natural beauty, but they were still just animals. Celestia would not entertain the very idea of laying with these animals, no sir. She turned around, intent on flying over the fence and fleeing the way she came… and she almost ran muzzle first into the dripping pussy of a mare. The animal looked over her back with a nicker of invitation, the mare shaking her rump in Celestia’s face.

Celestia stood still, frozen by the glorious sight; it turned out horses were quite similar to ponies back there too. The mare had a shapely rump, her wide hips betraying her use as a breeding animal; they looked perfect to hold on to while being mounted. The mare’s puffy slit had big fat lips, engorged with excitement, bigger than an Equestrian female, her arousal dripping from her entrance shamelessly. Her pussy lips were as black as she was, but in the center of her folds Celestia could see hints of pink, the mare’s fleshy insides peeking at her, waiting to be filled. The mare whinnied in impatience, and her folds spread open in a vulgar display of lust; Celestia had a glimpse of her oozing tunnel, her inner folds pulsating in need, ready to clamp around a stallionhood, ready to milk it dry. Her folds snapped shut before Celestia could see more, a spray of mare-juices squirting from her slit, the heated perfume splashing on the alicorn’s muzzle.

Celestia inhaled sharply, the concentrated dose of pheromones scrambling her brain, her tongue darting out to collect a sample of the liquid running on her lips… before she started to lick her muzzle clean, savoring every drop. Her stallionhood was now drumming against her belly, the length throbbing in need, the mare wiggling her rear in a shameless request to be fucked. Celestia’s hooves kicked against the straw, preparing to rear back, the mare squared her hooves expecting to be mounted… but the alicorn only pressed her muzzle into the mare’s cunt, lapping at it hungrily. The disappointed nicker from the mare quickly turning into a grunt of pleasure, Celestia’s tongue exploring her slit, teasing her opening. Celestia licked, sucked, nibbled on the mare’s slit, her mind focused on only one idea: she couldn’t fuck these mares, but she couldn’t just leave them in this sorry state. It was her duty as Equestrian ambassador to help them as best she could.

With a thousand year of experience at pleasing a mare, Celestia knew exactly where to press her long tongue, her licks sending the poor mare into a frenzy. The mare whinnied loudly, her flanks quivering, her folds winking for a second time; Celestia took the opportunity to plunge her tongue deep into her pink pussy. The mare cried out in surprise, surely not used to this type of service, but Celestia didn’t let up; she licked every nook and cranny she could reach, low moans escaping her throat as she savored the mare’s arousal. The mare pressed her rear into Celestia’s muzzle, trying to get her deeper, but Celestia only puller her tongue back. She ignored the mare’s imploring whinnies, waiting for the next wink; when the mare’s flesh opened again her pink clitoris was completely exposed, engorged with blood and desperate for attention. Celestia smirked, and she plunged back in, taking the mare’s clit between her lips.

The mare instantly came, the poor animal obviously on a hair’s trigger, but still Celestia kept sucking on her fat clit, her tongue giving the sensitive nub expert licks, sending the mare into a mind shattering orgasm. As the finishing blow, Celestia summoned a large magical stalionhood inside the mare's pussy, the large golden rod growing to fill her completely, and she begun to thrust. Female juices exploded from the stuffed cunt, splashing on Celestia's muzzle, and the alicorn's cock let loose a spurt of precum that splashed on the mare's trembling legs. The mare made a strange gurgling noise, and she promptly collapsed into the straw bedding, her legs kicking out cutely as she kept cumming, her eyes unfocused. Celestia stood over the twitching mare, giving her magical dildo a few last thrusts before letting it fade away, her breath short, mare-cum oozing all over her muzzle. Yes, this was fine, she could just service all these mares -and get a good meal out of it- without having to fuck them and break any bestiality taboos. She could do this.

Celestia turned to the rest of the herd, a confident grin on her messy muzzle, and she found herself looking at a wall of shapely rears pressed tightly against one another. Her smile fell, her eyes bulging out; there were twitching cunts winking everywhere, pink flesh contrasting sharply with their dark coats, all of them desperate to be filled. The smell of mares in heat was now overwhelming, the call to mate thick in the air, calling for Celestia's inner stallion. She couldn’t do this, she couldn’t do this, she couldn’t…

A mare appeared at her side, the animal nipping at her shoulder playfully. Celestia tried to shy away, but the mare only slipped under her neck, pressing her back to her chest. The mare slithered in place, Celestia’s leg naturally moving to embrace her, and before she knew it she was straddling the smaller mare, her cock probing her rear, flare brushing against something incredibly soft and wet, her cock lurching ahead as it began to sink between her oozing… GET OFF!

Celestia grunted as she jumped away from the disappointed mare, the horse whinnying at her as it turned around and shook her rump, inviting her back. Celestia’s hooves kicked against the straw, her body hankering to mount, but she managed to turn away… only to bump into another firm black rear. Celestia instinctually reared up, her hooves latching on to the mare’s hips, her chest sliding over the mare’s croup as she mounted the horse without thought. Celestia froze when she realized what she was doing, her cock sitting pressed against the mare’s dripping slit, her folds winking madly against her flare, trying to draw her in. Celestia grunted as her cock jerked in excitement, a spray of precum bursting from her tip and into the mare’s pussy. The animal whinnied in need, then quite unexpectedly threw her hips back; Celestia shuddered as her flare started to sink into the warm horse-cunt, the oozing walls hugging her tip, begging her to thrust inside. But the mare was only rewarded with a few new bursts of precum.

With a mighty show of will, Celestia managed to dismount, the alicorn wobbling drunkenly as she stared at the oozing pussy she had left behind, her precum leaking from the mare’s slit. Another mare bumped her rump against her sides, and Celestia shied away, only for her chest to land against yet another mare’s plump rear. Before Celestia could push her away however, this mare looked over her shoulder and snorted angrily, giving Celestia the stink eye. Celestia stopped in her tracks, recognizing the mare; it was the Head Mare, the leader of this herd, the most beautiful of them all, offering herself to her in such a submissive way. The Head Mare gave her a look that could only be interpreted as “You don’t have the balls to do it”, then she started to walk away, her tail lashing out to slap Celestia's muzzle, the hairs damp with her arousal. This was the last straw.

Whinnying like a mad stallion, Celestia reared back and mounted the haughty mare, her superior size becoming apparent as she landed on her back. The Head Mare tried to buck her off, still stubborn to the end and Celestia's hooked her hooves around her foal-bearing hips to keep her still, ready to be plowed. Celestia snorted, drawing the mare closer, her stallionhood finding her slit with expert precision, the large flare slipping inside with little resistance. The Head Mare looked back, giving Celestia one last arrogant look, and the alicorn rammed into her without restraint. They both screamed in pleasure, the mare a shrill whinny, Celestia a guttural moan, the two of them united as the enormous stallionhood plunged to the hilt. The Head Mare’s pussy was loose enough for Celestia’s large cock to surge all the way to her depths, but as soon as her flare hit her cervix, her walls clamped down like a vice, making her tunnel too tight to move.

Celestia panted atop her mate, her mind in turmoil. She had done it now, no going back. She was balls deep into an Earth horse female, her medial ring even managing to slip inside the Head Mare’s cunt, something very few Equestrian mares could hope to achieve. This was wrong, this was debauched, this was… hot. With a lustful whinny Celestia threw her hips back, the Head Mare snorting as she tried to hold on to Celestia’s cock with her clamping insides, but the alicorn was just too strong. Celestia’s stallionhood was squeezed on all sides as it slowly pulled out, her flare scraping against the mare’s velvety insides, streams of precum leaking from her tip. The Head Mare wiggled her hips, trying dislodge Celestia, still trying to be difficult, but Celestia had had enough.

The mare whinnied angrily as Celestia’s magic pulled on her mane, immobilizing her. The alicorn’s gaze swept the walls, ignoring the herd of mares currently watching her dominate their leader, and she found what she was looking for: a bridle and reins. The Head Mare nickered in protest as she saw the tools floating closer, but her cries were silenced as Celestia strapped it to her muzzle, the bit inserted into her mouth with little gentleness, the alicorn pulling on the reins forcefully to keep her steady; it might be harsh, but Celestia knew that’s how she wanted it. Celestia took the reins in her mouth, pulling back her horse, and she resumed her ride. Her second thrust was much less smooth than the first, the Head Mare clenching her insides to protest Celestia putting a muzzle on her, but Celestia was unrelenting; she was balls deep inside her mare in just a few blissful instants, enjoying her grasping tunnel. She repeated her slow thrust a third time, then a fourth, all the while pulling on the reins to show the Head Mare who’s boss.

Celestia kept her smooth rhythm, intent on breaking this stubborn mare, make her yield to her authority; but the Head Mare still resisted, even when it was clear she wanted it just as bad as the other mares waiting for their turn. Snorting in frustration, Celestia started to pick up the pace, a little at first, then a little faster, and before long she was railing her mate without restraint, her hips slamming into her plump rear without mercy. White fur pounded against black coat, Celestia had never been so animalistic when she had made love before, she had never fucked anypony quite so brutally; but that was the point. She wasn’t making love to this mare, she was fucking her into submission; she fucked her fast, she fucked her hard, she fucked her deep. This was pure, unrestrained feral mating, without complications, without strings attached, only the pleasure of flesh. Celestia whinnied like a wild stallion, completely letting go of her inhibitions, and on the next thrust she savagely bit down on her mare’s neck.

The Head Mare nickered around the bit in her mouth, and her whole body seized as she came quite suddenly. Her pussy clenched down on Celestia’s cock, and the alicorn paused, balls deep, to enjoy the massage of her spasming walls. Celestia’s flare was pressed against the mare’s cervix, and she could feel the entrance to her womb opening as the Head Mare came again and again; the warmth against her tip sent Celestia into a rutting frenzy, her hips drawing back and slamming into her mate without pause. The Head Mare was still cumming, but she could only hold on and be along for the ride at this point, her body shaking as Celestia hammered into her pussy.

Before long Celestia’s thrusts lost all sense of rhythm, her hips humping chaotically, the frantic pounding making the mares all around nicker in anticipation; they knew their turns would be coming soon. But Celestia hesitated: the mares were obviously all in heat, was it really okay to cum inside them? She probably wouldn’t have the strength to pull out anyway, but still, was this okay? Of course it was, a voice answered in her mind; they were different species, from different worlds, from different universes. What were the odds of them being compatible? She would just satisfy the burning in their wombs for a little while, really she was just being kind to them. Comforted in her choice, Celestia resumed her crazed thrusting, quickly building up her own climax.

Feeling she was nearing her end, the other mares started to crowd around the coupling dominant mares, each one hoping to be next. They started to lick Celestia’s coat, all of them making sweet nickering noises, vying for her attention. Celestia looked around imperiously, staring down at her harem, choosing her next mate. She found a petite mare that resembled a pony she had always found attractive, Fleur de Lis, and she leaned towards her while she gave the last couple of thrusts into the Lead Mare.

“You’re next.” Celestia said, looking the small mare in the eyes, her dominant tone making her quiver in anticipation. The other mares whinnied in distress, all of them redoubling in efforts to get her good graces, but Celestia didn’t care; they would all receive her seed by the end of the night anyway. She turned back to her mate, taking the reins in her magic, and pulled forcefully, the Head Mare nickering submissively. "And you, my little mare, you're mine!"

With a deep commanding whinny of pleasure, Celestia rammed into her mare one last time, her balls slapping against her belly as she bottomed out. She grunted, feeling her cantaloupe sized testicules clench mightily, her cum rushing down her length as she pressed her flare as deep as it could go, her tip poking inside the Head Mare’s womb. She hugged her mate tight, her whole being focused on claiming this beautiful mare, mark her as her property. Celestia held back her orgasm as long as she could, and just as her seed was about to burst into her mate she let go, screaming hoarsely without restraint.

Ropes after ropes of thick alicorn seed sprayed into the mare’s womb, the Head Mare whinnying around her bridle as she came again. Celestia rammed her hips back and forth with every spurt, milking her release to the end, a deep animalistic sense of pride filling her chest as she filled her mate with her potent semen. She had never been able to cum quite so liberally inside her mates before, for fear of creating heirs that would turn Equestrian politics into a nightmare, but with this mare she could just release her load without second thoughts. She playfully pulled on the reins as she hilted once more, her cum bursting around her cock, the Head Mare apparently filled to the absolute brim. And still the mare's pussy clenched around her spurting cock, apparently still thirsty for more baby batter.

Celestia knew she couldn’t get pregnant from her, but still, she found herself thinking about her virile sperm flooding her receptive womb, and she imagined the Head Mare carrying her foals. Her next shot was especially thick and copious, as if her balls responded to her fantasy, and were doing their best to make it a reality. Celestia looked down at her mate, put the image of the Head Mare round with her foals into her mind, and she hilted with a long moan to discharge the last of her seed deep into her broodmare, her load thick as glue as she focused on the silly idea of impregnating her.

The mare beneath quivered in blissful agony, and she collapsed in a heap when Celestia pulled her still-hard cock from her messy cunt in a shower of spunk. The Head Mare remained on the ground, heaving in exhaustion, her pussy oozing with thick, alicorn semen, the bridle still on her muzzle; she could wear it forever, as far as Celestia was concerned. The alicorn used her magic to aim her cock at her conquered opponent, drawing the remnants of her seed out; her black coat was now streaked with white, Celestia’s color and scent marring her pretty fur. The gorgeous female was now hers, inside and out. Mares all around shuffled to present their backsides to the virile stallion in their midst, but Celestia only had eyes for one.

The petite black mare was panting in need as she watched Celestia approach, and she turned around without hesitation, her tail flicked to the side. She nickered softly as Celestia lost no time in mounting over the much smaller mare, her enormous cock straining to enter the tight mare; one commanding push was enough to conquer her narrow slit. Celestia grunted as she quickly bottomed out, a good portion of her cock still sitting outside; she pounded into the petit mare without restraint, frustrated over not being able to hilt.

While the mare neighed in pleasure, Celestia playing around with the thought of being on top of the supermodel Fleur de Lis, her depraved mind putting the white Prench pony in place of the black mare she was currently screwing. She used the mindless mare to fulfil her fantasy, and felt no remorse at all; they were amongst animals here, there was no place for shame. She imagined Fleur’s nasal cries as she was pounded into submission, her narrow pussy squeezing her from all sides.

“You are so beautiful Fleur…” Celestia whispered into the petite mare’s ear, no, into Fleur’s ear. “I’ve always found you so desirable…” Her hips rammed into Fleur’s firm shapely rear, her release building quickly thanks to her fantasy. “Just think of how beautiful our children would be… Will you bear my foals?” Fleur whinnied like a feral horse, and Celestia grinned wide. “I’ll take that as a yes.” Her hips turned into a blur, her flare growing inside Fleur’s tight pussy. “Give… my… regards… to… Fancy pants…” Celestia grunted, holding her orgasm back as long as she could, then she slammed home and remained there.

With a triumphant cry Celestia came for a second time, her release as prodigious as the first thanks to her alicorn biology. She pressed as deep as she could, her mind focusing on breeding Fleur, the image of the white mare swearing in Prench under her flickering with the feral mare accepting all her seed without a peep, until only the feral mare remained. Celestia pressed her muzzle into the mares cheeks, giving her gentle loving kisses while she savagely packed her cum into her little womb; enough to knock her up three times over. Soon Celestia’s own release started to push her cock back, the petite mare unable to contain it all, and Celestia withdrew her still spurting length in a huff.

There was a flurry of legs as the mares fought for position, and Celestia threw her hooves around the first black rump that hit her chest, uncaring for who it was; she only wanted to spread her seed around, satisfy the herd, claim them all as her own. Her own little herd of broodmares to breed endlessly. She came in long urgent shots as she thrust into this new mare, cum spurting everywhere as she pounded into her messily, until she managed to hilt and remained still to fill this mare with her seed and her foals. There was little thoughts left in Celestia’s mind, she was solely focused on three things: mate, claim, breed. Almost as feral as the mares pressing into her, Celestia quickly dismounted only to jump on top of the closest mare, her cock still spurting continuously.

She didn’t know how long she kept going, the cycles of mounting, womb filling, dismounting and remounting starting to blur together. Celestia was but an animal amongst other animals, a beast driven by instincts. When she came to she was balls deep into a neighing mare, her seed already overflowing from her cunt; she had been using this one for some time apparently. One look around gave her an idea why: she was the last mare still standing. All around she could see the panting bodies of her herd, all of them oozing with her semen, some even sporting bumps on their bellies, their wombs so bloated with cum that they appeared already pregnant. With a grunt she shot one last load into her current partner, then pulled back in one smooth motion. The mare collapsed on the ground, completely exhausted.

Celestia panted hard, her body sore and her hips on fire; her cock felt like it had been through a hundred mares, and it probably had. Her stallionhood was finally allowed to flag, her bruised length starting to go limp; she still had to deal with the layers of cum and mare-juices that clung to it though. She gave the piles of filled mares a look, then saw just was she needed. With a snort she walked over to the groggy Head Mare, her coat streaked over with dried cum; just how long has she been fucking these mares? Celestia carefully removed the bridle from her muzzle, the mare watching her suspiciously. Smiling, Celestia used her magic to hold her muzzle open, and without a moments hesitation she stuffed her cock down the Head Mare’s throat.

The mare gurgled in a panic around her length, clearly new to the concept of “blowjob”, and Celestia kindly removed her length long enough for the mare to take a breath… before thrusting back inside. The mare offered a token bit of resistance, before she finally surrendered totally to her new leader, the mare swallowing around Celestia’s cock obediently. Celestia enjoyed herself until her flagging length started to grow hard again, then she quickly removed her cock from the former Head Mare’s muzzle. She had done a good job, Celestia’s cock was now only partially covered in cum and pussy juice; it would have to do, Celestia could hear roosters crowing outside. She leaned down to give her favorite a quick peck on the muzzle, then hurried to get away before any human caught her. Had she really spent the whole night inside the barn, mating with the mares? It seemed so.

Wincing with every step, her hips screaming in pain, Celestia carefully made her way around the battered bodies of her passed out broodmares, each stuffed to the brim with her seed. It was a good thing they couldn’t get pregnant, or this could be very bad. With a burst of her horn the light spheres disappeared, plunging the barn back into darkness, the snoozing mares inside disappearing from view. Celestia gave her little harem one last look, then she slipped out the door, hoping she wouldn’t be caught by anyone.

Particularly by her sister.
