It's been a month since Twilight Sparkle began her new life in the Equestrian Girls universe. For a pony turned human, life has been relatively normal. I say "relatively normal" because most people don't have to go through the excruciating process of having all of their bones scattered and rearranged when transforming from a pony to a human, and because Twilight still has to go through her monthly estrus. Estrus in women is much worst than in ponies: their soft bodies burn with the desire to mate; they're constantly dehydrated from sweating all over and their tight little vaginas winking nonstop; they have the uncontrollable urge to present their buttocks to the whole world, and to mate with anything that moves; and their sexuality is oriented toward stallions, geldings, mares, or a combination thereof.
Twilight didn't know what was happening to her. She thought she was sick, so she saw the school nurse, Nurse Redheart. Redheart gave her a checkup - groping her breasts and her ass, lifting her skirt to finger the soaking wet cameltoe in her panties, sucking on a thermometer like it was a glass dildo before sliding it into her mouth, and giving her French kisses that almost made her faint - but, apart from the high temperature that Redheart alleviated by stripping Twilight and herself down, laying on the cool examination table, and rubbing her body against Twilight (her huge breasts engulfing Twilight's face, her drooling mature pussy humping Twilight's inexperienced schoolgirl pussy), there was nothing unusual found. After Redheart opened the office's windows to air out the hot thick musk of sex, she told Twilight to return to her class. Shaking, lipstick covered Twilight clumsily half-dressed and left the nurse's office.
But along the way to class, Twilight was struck down on the ground - face down, ass up - by a powerful vision that only made her sweatier, hotter, and hornier. She saw a white mare's big fat ass, its lush tail wagging seductively at her, letting her get glimpses of its winking clitoris and puffy donut-like anus. Horny Twilight pulled her face out of a puddle of her own drool, jumped to her feet, and ran from Canterlot High School to the farm that her class had gone on a field trip to last week: Appaloosa Acres. She couldn't take it anymore. And her school uniform felt too uncomfortable now to wear. She dashed, leaving behind a trail of clothes for someone to sniff at while they schlick, down the street, through the town, over the Appaloosa wood fence, threading fields of gold and green, and into the big red barn. Fortunately there was nobody to notice her running naked through the city or trespassing on farmland. Twilight wouldn't know to what to say if she got caught, but the humiliation probably wouldn't override her urges; if she was arrested, she'd probably overpower the police and just rape them like a wild beast.
The smell of fresh hay and freshly washed horses hit Twilight like a ton of bricks as she entered the dimly lit barn. Ten Appaloosa mares - bay, black, chestnut, palomino, buckskin, cremello, roan, gray, dun, and grulla - turned their heads, one by one, to stare at the intruder from the stalls. Like Twilight, they were all in heat. Unlike her, they wanted stallions. Twilight stood in the barn doorway, ogling the ten hefty butts facing her. So many buns, yet so little time. But she was going to take her time with each horse anyways. She headed for the bay mare, wiping the drool off her chin, and magically opened the stall. But seeing the fear yet wonder in the horse's eyes, Twilight yanked a spellbook out of her vagina - letting out a few slight moans of pain while she did - and opened the soggy book to a love spell. She quickly cast the spell on every mare, and immediately all twenty-four eyes became heart shaped. And shoving the spellbook back up her loose cooch while moaning, she got to work on satisfying herself. Twilight grabbed the bay by the hindquarters, her arms not nearly long enough to cup one haunch.
The hide was soft and smooth, yet warm and tough, to the touch. It was like a gigantic pillow or cloud. Twilight buried her hands in the buttock, and seeing them disappear made her giddier than ever. She jumped up onto the haunch and stuck to it, and she roamed around the mare's backside, rubbing and massaging and kneading each of its bootylicious buttocks. As she molested the mare, Twilight groaned with pleasure and sniffed with increasingly louder, deeper inhales. To make the horse even smellier, she licked every inch of its backside, tasting the horse's delicious meat and memorizing its lovely texture. Up to the top of the curvature of the bum, then back down to the thigh, and from one hip to the other. She came over again to the thick lush tail to give it a big whiff from bottom to top, and top to bottom, then lifted it to slide her face into the mare's deep hot crack. The big tail fell back down, hiding Twilight from view and muffling her groans and sniffings. She buried herself inside the mare's buttcrack, pushing and prodding her way to the tailhole. The mare grew hotter and tighter the deeper Twilight ventured, squeezing her in its intense inferno. It was as if the animal was helping her to reach its own butthole.
Twilight's nose bumped into the puffy, pulsating, donut-like anus. Her nose filled with the musk of sweat and feminine scent secreting from the ponut. The aroma made Twilight's brain short circuit. Every cell in her body now became flooded with lesbian desires. Her eyes rolled back, her tongue shot out. She jammed her mouth around the mare's anal ring to greedily suck and slobber on it, nibbling and slurping on the meat to pull it in as far down her throat as possible. Twilight loudly ate out the mare's ass. Her tongue angrily shot inside the anus to complete the French kiss, swirling around in the dank colon like a rape tentacle. The mare neighed loudly, convulsing with pleasure, and slammed its ass into the stall door to keep Twilight inside of its crack. A jet stream of pussy juice sprayed out, running down the horse's back legs and soaking the stall floor. The mare bowed to keep its head down and ass up. The other nine horses neighed nervously yet impatiently, eager yet afraid to receive Twilight's services.
The heat of the anus was unbearable, but Twilight had to tongue bathe and tongue fuck the bay. She suckled on the chewy bunghole furiously while she thrust her tongue in and out of the tight pipe. The aroma of the ass kept making her cum harder, but she kept on drinking up torrents of the ass sweat. Twilight was lost in heavenly pleasure; stuck in a mare's tight hot sweaty buttcrack, its cheeks wrapped totally around her body, its tail keeping her inside, its butt pressed up against the stall door so she couldn't escape, and her tongue stuck inside the vice grip of its asshole, melting in the fragrant heat. If every mare was this amazing, she thought, than she was going to become addicted to all ten Appaloosa. Just the thought of that made Twilight much on the mare's ass as hard as she could, deepthroating it. The loud, lewd noises of Twilight's analingus filled the air with the mare's neighs like a sweet melody. Screw being a princess, Twilight thought, I'd rather serve a mare's butt than rule in some stupid castle.
Corrupted ass-slave Twilight fed on the bay's ass for an hour. The other horses grew more apprehensive as time went by, some bucking their stall doors to let Twilight know that they had had enough of having to hear her greedy mouth service their friend - now it was time for her tongue to taste their butts too. When Twilight was finally finished, she fell onto the stall floor, exhausted, landing in a big puddle of pussy juice. The pussy juice leaked out of the stall when Twilight opened the door. No doubt the hands of Appaloosa Acres would be angry about having to clean up this mess; so Twilight lapped up the juice. Now with a full stomach, she headed for the stall across the barn where the palomino mare was kept. Then she headed for the other stalls, and let all the other mares out too. They circled around Twilight. They turned about. They stuck their buttocks out, and did the hokey-pokey, shaking them all about. The mares closed in to fence Twilight in their booties, then lifted their tails to present themselves. The mares' combined auras, the trails of their tails, was like a garden of pleasure for Twilight's lungs.
Twilight squee'd with pleasure, screaming out her undying love for mares and mares' perfect behinds. She hastily went from rear to rump, sniffing and whiffing, licking and smooching, each bootyhole, and became intoxicated on the horses' balms. Twilight shoved herself into each crack and her nose into each hole to breath in its heady essence. This was her air from now on. This was paradise, everything she ever wanted. Giant hot asses, smelly deep tailholes, lovely big tails, and gentle giant beasts to enjoy. Twilight kept sniffing louder and deeper the more she smelled the equids. She prodded and rubbed her nose inside the horses, and spanked and kneaded their haunches (as much as possible) while she did. The mares kept her inside their cracks with their tails, and sometimes they butt crushed her - one mare shoving into another that Twilight was servicing with her own butt - so that Twilight became trapped betwixt her mistresses. A slave to estrus, she was now a slave to beasts' bottoms - wholly corrupted.
This lesbian love session went on for nine hours, plus the hour that Twilight spent with the bay, until all nine mares were satisfied at dusk. Bathed in the sunset's light coming in through the barn's doorway, mind-broken Twilight did not care that this was the end of the day of friendship and the beginning of the night of lust - an eternal night for her. Stinking of sweat and ass and pussy juice, after drinking up the sweat inside nine humid buttcracks and lapping up the pussy juice that nine winking vaginas had leaked onto the barn floor, a messy-haired and full-bellied Twilight kissed her mistresses, one by one, on the lips. Not a peck, nor a long smooch, nor passionate lip-service, but a deep, soulful French kiss - an exchange of hearts, with thick ropes of saliva and a waging tongue fight inside their locked mouths. When the kiss broke, each mare locked her mouth around Twilight's mouth again, and again, and again; drowning her in tongue kisses, giving her mouth and lips and face many and much needed tongue baths.
If the ass service hadn't left Twilight in a daze, the endless kisses did. She stumbled from mare to mare, and they surprise attacked her with their big, full, wet, mature, hungry, scented, hot lips. All the while staring deep into her eyes with those big, gorgeous, gem-like eyes of theirs, communicating how much they loved her. After so much kissing, Twilight had to lean against a stall, her body convulsing so hard that she couldn't stand anymore. Her body felt so hot, her skin was tingling, and she was near to passing out from so much pleasure. Yet she wanted to get back behind each mare and serve them forever, even make her home in their cracks so that she could live inside them like the good little maid that she was. As if the horses understood Twilight, they crowed around Twilight, and turned about with lifted tails. The night was young, each mare said with her eyes as she looked back at Twilight, and we're still horny. Twilight gazed at the wall of mare asses in fear yet desire, and the wall pressed itself right against her.
