Bonus chapter: The Other Barn

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.
