Shining Armor anxiously trotted bout his room, occasionally casting glances at a rather ominous letter sitting on his bed. When his sister, Twilight Sparkle, had come prancing to his bedroom door with the envelope in hoof, he’d been more than a little curious. It was rare for him to receive mail at home and, as such, he wondered who would have gone through the trouble to send him something. Upon spying the ornate and filigreed letter, the stallion’s wonder soon turned to dread. Celestia, princess of the sun and ruler of all Equestria, had requested an audience with him, and he had no idea why.
Admittedly, the stallion had spent far longer on this trip home than he’d originally intended. What began as a friendly visit to his family, taking a short break from his schooling at the royal guard academy, had quickly transformed into a lewd adventure of depravity and self realization for Shining Armor. Shortly after arriving, the white unicorn had succumbed to the wanton advances of Twilight Sparkle and Twilight Velvet. He had, in truth, always held a deep seated interest in stallions and dickmares, like his sibling and mother, even having purchased a sex toy to simulate the experience at one point. The precocious purple filly and older, grey mare had simply allowed him to take the first steps down a path that, until recently, he’d been to timid to take.
His mother and sister, wanting nothing more than to help their dear brother achieve his dreams, set themselves to task. Together, they gradually educated him and molded his body into the effeminate creature which he had become. Shining had steadily received doses of transformative potions, altering is figure and softening his features. The alabaster unicorn was instructed and drilled ruthlessly on how to best service a hot, throbbing shaft using all manner of erotic techniques. His mouth, throat, and tail hole, had all been extensively trained to deliver pleasure to nearly any lover. The stallion’s mane and tail, once shortly cropped and well kept, were both now beautifully voluminous and well styled. Gone were the once chiseled muscles and roguish good looks the unicorn had one possessed, replaced with wide, foal bearing hips, soft curves, and a svelte frame. Shining had even been learning about what makeup and alluring garments best accentuated his marish form, further magnifying his femininity. Twilight and Velvet had even, as of late, been taking him out into public while gussied up like a mare, parading him about town, leaving stallions and dickmares casting lustful glances in his direction.
Princess Celestia had even granted the Shining an extended leave of absence from the guard academy, allowing him stay with his family throughout his metamorphoses. Of course, the alicorn hadn’t known the real reason for his protracted vacation, having been informed by Twilight, her star pupil, that the stallion was simply enjoying his time at home. At least, that’s what he’d been lead to believe. It was a painfully simple bit of deception, one which would soon crumble to pieces as Shining was to meet with the princess the very next day.
The letter he’d received, while polite, had firmly asked Shining to come to the Canterlot castle the morning after delivery. Now, if traditional mail had been used, the stallion may have been able to buy an extra day or two, claiming a delay in receiving it, but one of the princess’s personal couriers had placed it directly in his sister’s hooves. As such, he had less than a day to prepare for his meeting with the most important pony in all of Equestria. He was so frazzled, he didn’t know where to start or what to do.
“Oh come on Shiny, it’s nothing to worry about,” Twilight groaned, watching from atop the mattress as he paced about his room. “Princess Celestia is super friendly. Really, you’re just working yourself up,” the filly continued. She really did feel bad for her brother and would do what she could to help him, even if it meant forgoing her normal advances on his hindquarters.
“I just know she’s gotta be mad. It’s been just over two months and I haven’t been back to the academy once!” Shining lamented, trotting over to the bed and resting his head on the blanket beside his sister. All he could do was look presentable, plead his case, and hope the alicorn would accept his apology. He already realized that his absence would likely push his graduation back, having missed such a sizeable portion of a semester.
Twilight patted his head with a hoof, stroking his mane comfortingly. “Look, how about you just get some sleep. It’s already late and there’s no sense in staying up all night to worry about it. Besides, you wouldn’t want to show up for the princess with bags under your eyes!” the filly teased, smiling at the effeminate stallion. “And,” she gently admonished, holding up a hoof, “a mare like yourself needs her beauty sleep.”
“Twi, Celestia doesn’t know about any of this! As far as she’s concerned, I’m one of her cadets, not some fem-colt,” he moaned, tears in his eyes as he pulled a pillow over his head. Shining hadn’t the slightest idea what the princess would do when she saw him like this. He’d likely be expelled from the academy and be forced to move back home. Shame of failure aside, the stallion didn’t have a clue what he’d do if the worst came to pass. All his life had been spent preparing to become a royal guard but, after coming to terms with himself and being able to live out his deepest fantasies, he wasn’t sure what the future held for him. It was almost as if he’d been cut adrift in an endless ocean with no sail or direction.
“Shining,” Twilight chirped, tossing the pillow off her brother’s head and taking his face in her tiny hooves, “Celestia is the kindest, most caring pony I’ve ever met. Look, I’ll even go with you tomorrow morning to help plead your case.” She only had one brother, and she cared for him dearly. After all, Shining was her BBBBF, and nothing would ever change that.
The stallion flung himself upon the little filly, wrapping his forelegs around her and hugging her tightly. “Thank you so much Twi! Thank you, thank you, thank you!” he exclaimed. Regardless of exactly what Celestia had summoned him for, having the princess’s prodigal student present could potentially improve the alicorn’s mood or, at the very least, it couldn’t make the situation any worse.
“It’s no problem,” the purple unicorn assured him, wriggling out of his grasp before hopping down to the floor. “You just get some rest and we’ll handle it tomorrow,” she continued, trotting to the door as her brother crawled onto the bed. “Here,” she whispered, a soft magenta light drifting from her horn towards the stallion, “this should help.” A simple sleeping-aid spell certainly wouldn’t hurt Shining in the slightest, as worked up as he was. Flipping a switch by the door, Twilight extinguished the lights, before leaving her brother as she went to retire in her own room for the night.
As Twilight’s spell settled upon him, Shining’s eyelids grew heavy. His sister had always been supremely skilled with magic, so he wasn’t surprised she’d been able to knock him out with ease. The stallion quickly dozed off and fell into a fitful slumber. Sadly, it was a preternatural bout of sleep, one of those experiences where, as soon as one closes their eyes, hours pass by in mere moments. Before Shining knew it, the morning sun was peeking through his window, casting light over his face and causing him to stir.
Pushing himself upward, the alabaster unicorn rubbed the crust from his eyes. Rolling from the bed, he trotted off to shower. There was no use in putting off the inevitable so, steeling his resolve, Shining Armor prepared himself as best he could. After washing up, he donned his armor, or tried to at least. Unfortunately, his supple posterior and slender frame no longer filled out his guard uniform properly. Some areas of the armor were a bit too snug, while others clattered and hung loosely. All told, it wasn’t the best way to start the day. Still, the stallion persisted, putting on the outfit before heading downstairs. Twilight and Velvet awaited him in the kitchen, smiling warmly as he came into view.
“I know you’re nervous, but I’m sure it’ll be fine,” Velvet softly said, giving her son a hug and handing him an apple.
“And I’m going with him, so I’ll make sure he’s alright,” Twilight added, circling her brother and playfully smacking his backside. “I’m not sure why Celestia wanted to see you but, like mom said, it shouldn’t be anything to be concerned about!” she chirped, beaming up at her sibling. Of course, she absolutely did know what the meeting was going to be about, being Celestia’s protégé, but she wasn’t going to spoil the surprise. She spoke with the princess on a regular basis, discussing matters both academic and social. It should come as no shock that Twilight mentioned her dear brother, regaling the princess with Shining’s salacious exploits. Still, the alicorn had been hard to read, curtly nodding and mentioning that she may be interested in speaking with him to lend him aid. Thus, some short time later, the stallion had received the letter, leaving them where they were now.
After Velvet wished the two luck, the siblings left the house. It wasn’t long before the white stallion and purple filly stood at the steps of the Canterlot castle. Taking a breath to calm himself, Shining led the way, trotting up to the the vaulted entrance before stepping inside. Passing by a pair of guards, he smugly noted as the two ogled him, slipping glances in his direction. Flipping the blue mane from his face, he shot one of them a wink and cheeky grin. Even though he was dreading the meeting with the princess, being a little flirty beforehoof certainly couldn’t hurt. Then, out of nowhere, he remembered. His mane and tail, each having grown out substantially, now stood in outright defiance of regulation length. Despite himself, Shining chuckled, shrugging as he continued towards the throne room. He was well aware that he must look like some bawdy parody of a soldier, but there was little he could do about it now. Winding their way through a series of corridors, the brother and sister soon found themselves standing just outside the Princess’s audience hall.
“Ladies first,” Twilight giggled, motioning the curvaceous stallion forward.
Shining took a breath, steadying his nerves before pushing the doorway open. There, at the far end of the room, on a raised dais, sat the princess of the sun. He’d only ever met her on one occasion, and it had been a terribly fleeting moment. Once, while at the academy, she’d paid the cadets a visit, looking them over on the parade grounds while offering words of encouragement. Even though she was Twilight’s mentor, he’d never had the opportunity to speak with her directly, finding himself too busy with his studies.
“Come in, please. Oh, and do shut the door behind you,” Celestia called out, her voice soft and inviting, despite her size and power.
As the two approached the princess, Shining took stock of just how large she was. Even though he was a fully grown stallion, regardless of his marish figure, the alicorn was of an amazing stature. Sitting though she was, he could tell she was easily a full head and shoulders taller than he was. Reaching the foot of her dais, the stallion knelt, bowing his head reverently. Twilight, however, simply scampered up the stairs to hug the princess.
“See, I told you she was cute,” Twight snickered, nuzzling her snout to the alicorn’s fuzzy chest.
The stallion groaned at his sister’s words. She and his mother had both routinely referred to him as her or she, further reinforcing his flowering feminine nature and mindset. “You summoned me Ma’am,” he asked, continuing to cast his gaze downward at the immaculately polished marble floor.
“Right to business, I can appreciate that,” Celestia replied, steadily getting to her hooves before descending towards the stallion. After hearing about Shining Armor from his sister, she’d been more than a little intrigued. There were few things that mattered more to her than the contentment and happiness of her subjects and, as such, she’d considered Twilight and Velvet’s efforts a valiant one. There were, and always had been, ponies who, for whatever reason, were reluctant to accept themselves for who they really were. After hearing about the stallion’s predilections and repressed urges, she’d given the mother and daughter her blessing to coax them out, granting a leave of absence for the stallion as his latent desires were nurtured and brought to the fore. She really had to admit, he was quite fetching, rivaling many mares with his allure. “Rise, let me have a look at you,” the alicorn quietly commanded.
Shining did as asked, standing proudly and looking forward while the princess slowly circled him. He tried not to fixate on the butterflies in his stomach as the demigod studied every inch of him. A single bead of sweat formed on his brow when the alicorn leaned in, inspecting his face with her magenta eyes. As she retracted, a thoughtful expression on her face, he breathed a sigh of relief. Regrettably, all the anxiety from before, magnified several times over, returned as the princess spoke.
“Well, I’m sorry to say this but, you are the most ridiculous guard pony I’ve ever seen,” Celestia murmured, the warmth of her smile standing in stark contrast to the soul crushing words. “Your mane is far too long and luxurious, your body is soft and a bit plump in places, and your hooves are far too well groomed for a stallion who’s to be trained in the art of combat,” she continued, each comment biting like a knife into the cadet. The princess paused, waiting a moment for everything to sink in. Over the millennia, she’d discovered that timing was everything. “It’s almost as if you’re more of a princess than a soldier,” she politely remarked, carefully watching the stallion. Sure enough, he gulped, his heart rate and breathing immediately quickening. It was a nibble, not quite the bite she’d been looking for, so Celestia went in for the kill. Bringing her muzzle to the side of Shining’s head, she breathed hotly in his ear. “Perhaps you’d enjoy serving as my princess,” she whispered, her heavily lidded eyes gazing into the stallion’s own as he finally looked at her.
He didn’t know what to say! All Shining could manage to do was stand there, his jaw flapping silently as he fought to form a response. The last thing he’d expected was the have the glorious astral goddess of their empire make advances upon him and, as such, he nodded dumbly, blushing like a filly who’d just been complimented by their crush.
“Now,” the princess sighed, taking a few steps away from the shocked stallion, “be a good little mare and strip for me.” Celestia looked back over her shoulder, a devilish glint in her eyes as she looked upon the white unicorn. “That uniform is unbecoming and we simply must get you into something a bit more fitting,” she explained, waiting for his reaction.
With a shaky hoof, Shining began to do as asked, unclasping the various portions of his armor before setting them to the floor; all the while, Twilight and the alicorn watched him. Although he’d had no idea that he’d be performing a show for his sister and the princess, here he was, doing that very thing. Emboldened by their hungry stares, his motions slowed, becoming more steady as he stripped himself. The stallion carefully slid the plate over his rump, allowing the cool metal to dig into his soft fur. With a flourish, his helmet clattering to the floor, he flipped his mane, shaking his head about and enjoying the cool air as it caressed him. Though the outfit wasn’t uncomfortable, it could get a bit warm, particularly under the lustful gaze of royalty. After finishing, he turned and bowed for the princess, awaiting her next order.
“I told you she was pretty hot too,” Twilight commented, trotting up beside her mentor. The filly’s horn glowed, sending a wave of magic over herself as she undid her concealment spell. Her marecock, nearly as big as one of her legs, dangled freely from her groin, semi-erect as she watched her epicene sibling.
“I completely agree. Thank goodness I prepared accordingly,” Celestia said, giving the floor three quick taps with a hoof. On cue, a pair of her praetorians entered the chamber, pulling a small cart behind them. On the little wagon sat a resplendent chest, bedecked in jewels and with golden accents. The soldiers trotted to their princess, only stopping to unload the ornate trunk. “Thank you, you are dismissed,” the alicorn demurely intoned. Saluting the princess, the two armor clad ponies turned, returning to the hallway and closing the door behind them. “Shining,” Celestia called, drawing the stallion’s attention. “Please, if you’d be so kind,” she quietly added, sweeping a hoof towards the chest.
Making his way over to the opulent trunk, the stallion carefully opened it. Inside lay the most beautiful gown he’d ever laid eyes upon. Retrieving the garment, and holding it aloft, Shining admired just how stunning it was. The dress was made from long, flowing, sky blue fabric, masterfully embroidered and inlaid with silver filigree. Looking back in the chest, he realized there was even a diamond choker, leggings, negligee, and garter belt. The princess had brought him an entire outfit and, judging from the looks of it all, everything had been made to fit him perfectly.
“Is it not to your liking?” the alicorn asked, her smile faltering as the stallion stared in awe at the ensemble.
“No! No, no, no, it’s not that!” Shining bleated, feeling awful for even having given the princess such an absurd notion.
“I was dearly hoping you’d try it on…” Celestia sighed, turning her head ever so slightly away.
Without a word, the stallion began to don the outfit, albeit cautiously. He’d feel absolutely terrible if he were to damage such impeccably crafted attire. Although he wasn’t all that well acquainted with the price of such finery, the unicorn knew it must have cost a small fortune. As he thought, everything had been tailored to fit him flawlessly. The fabric itself was some manner of silk, gliding over his coat and exposed hide. Tugging the final legging into place, and clipping it to his garter belt, Shining addressed the princess. He smiled sheepishly, if not a bit awkwardly, at the fact that he was missing his makeup.
“My, my, my,” Celestia cooed, her eyes alight as they settled upon the effeminate stallion. “If I hadn’t known any better, I’d have mistaken you for a princess yourself,” she added with a slight titter. There was no malice there, not the slightest vestige of mocking tone or sarcasm. The princess’s words were sincere, and she was truly moved by the stallion’s beauty, all parts of her. “I do believe you’re missing something though,” the mused, trotting over to face him. Golden energy surrounded her horn as the princess levitated the crown from her head. Hovering the tiara over, the alicorn daintily set it atop Shining’s brow. “Perfect, simply perfect,” she murmured, taking a step back to appreciate his elegance.
Shining’s blush deepened as the princess spoke. He was simply besides himself with joy, squirming in place as the two mares admired him. Movement below Celestia drew his attention downward, and his jaw nearly hit the floor at what he saw. A massive log of flesh hung below the alicorn, peachy flesh toned and glistening with sweat. Now, he’d seen his fair share of pony equipment, both on stallions and dickmares, but this thing was, by far, the largest he’d ever set eyes upon. Twilight’s was large by any ordinary standards, over a foot long and as thick as one of her little purple legs, but the alicorn’s tool was a divine behemoth. If he had to guess, it was just under two feet in length and nearly double the girth of his sister’s, and it wasn’t even fully erect. The stallion gawked at it, swearing that it was getting harder by the second.
“It would appear the princess has a keen eye for royalty,” Celestia teased, turning and ascending her dais before seating herself. “Please,” she said, her thighs parting and allowing the weighty package between them to swing freely, twitching slightly in time with her heartbeat, “feel free to acquaint yourself.”
The stallion swallowed, his mouth beginning to water as he took a step closer to the seated alicorn. As Shining drew nearer, his sinuses were assaulted with a pungent musk, a heady concoction of floral notes, earthy tones, and stringent, sweaty accents. If it smelled this good, he could only imagine the taste. The concealment spell the princess had been using must have been multi-sensory, masking any visual or olfactory markers of the sizeable appendage hanging from her loins. He paused just shy of her crotch, marveling at the pair of white furred testicles. Each was roughly the size of a grapefruit and Shining wondered just how much they could produce; the thought caused a tingle of pleasure to run up his spine.
Noting the unicorn’s hesitancy, Celestia spoke up. “You can get a little closer. I assure you, I don’t bite,” she joked, flexing her pelvic muscles and causing her marecock to bob slightly. “I haven’t had a chance to shower today, so forgive me if my scent is a bit potent,” she added, watching as the stallion’s snout crept closer and closer, eventually pressing itself to the base of her shaft. It’s true that alicorn’s, beyond the obvious anatomical differences, held several, rather subtle biological distinctions compared to most ponies. Celestia, having realized Shining had already discovered one of them, was sure he’d be privy to the others in due time.
Shuffling forward, shining brought his muzzle to the trunk-like base of the princess’s member, his head swimming as he breathed in her pheromone laced bouquet; he nearly felt drunk because of it. It was as if his entire world was the alicorn or, more precisely, the heavenly cock and pendulous nuts before him. The stallion was so enrapt that he didn’t notice as a small, purple unicorn circled behind him.
Twilight, using her magic, daintily lifted her brother’s dress. She giggled, watching as Shining’s tail lifted, swaying to the side as he presented himself. Some primal part of him knew what she was doing reacted accordingly. The filly gazed at his pucker, swollen and pronounced from weeks upon weeks of training and constant use. Granted, she’d never bedded an actual mare, but she wouldn’t trade a nice piece of stallion ass for anything. Although she was still too short to mount him properly, she’d discovered that hopping up and wrapping her forelegs around his ample hips proved sufficient for her needs. Watching him sniff and caress the princess’s rod with his face, caused an idea to formulate.
“Shining, maybe you should get comfortable,” Twilight muttered. The little unicorn quickly seated herself on the steps beneath him, splaying her legs and allowing her mast like erection to loom just below her brother’s rump.
The feminine stallion shifted, lowering his hips as he sat, impaling himself upon his sister’s girthy rod at the same moment he licked the princess’s towering phallus. He came instantly, the sensation of the alicorn’s taste flooding over his palate, while Twilight’s marecock plunged into his backdoor and across his prostate, proved too much to bear. Thankfully, his dress was spared from the mess he made, as Celestia, using her sorcery, pulled it upward, allowing his feeble load to spatter harmlessly to the staircase. Groaning like a mare in heat, Shining licked and suckled upon princess’s loins while his sister began to feverishly thrust upward.
“Thank you Twilight, that’s very considerate of you to give my princess an appetizer before I deliver the main course,” Celestia whispered, reaching down to take the affectionate stallion’s face in her hooves, causing him to look up at her. “Dearest,” she sighed, freeing one hoof and angling her titanic length downward, bringing its head to meet his snout, “perhaps you’d like something to keep you from sounding so uncouth.” Her eyes went alight as Shining’s lips parted, his tongue lolling forth like the unfurling of a red carpet, eager to accept her offer. “There’s a good mare,” she sweetly murmured, slipping the tip into his hungry maw.
Having an impossibly large member, the biggest he’d ever encountered, pressing against the back of his throat, while a marginally smaller tool ravaged his backside, was astounding. Never in his life had Shining been this full, and he absolutely loved it. Rocking his hips, the stallion attempted to meet his sister’s furious movements. Twilight, while exceptionally well endowed, had never quite mastered the technique of pacing herself, always leaping upon the opportunity to plunge her length into a presented hole with reckless abandon. While the sensation of having his pillowy posterior plowed was, as always, a welcome one, Shining was far too focused on the girthy prick worming its way into his throat. It was a tight fit, but his perseverance was slowly paying off as he worked more and more of the alicorn’s dick down his gullet. Try as he might, the stallion couldn’t avoid a muted gag or stifled cough as he choked himself on the princess.
“Don’t hurt yourself Dear,” Celestia cooed, stroking the stallion’s mane as she watched him struggle. She had to admit, his tenacity was astounding. Very few could manage taking as much of her into their airway as he had, and the sight was quickly stoking the flames of passion within her.
“She’ll be fine...Umf...loves having a fat dick in her throat. Isn’t that right Shiny,” Twilight chided, slapping her sibling’s jiggly rear as she plundered its depths. She knew she wouldn’t last long at this rate, but that wasn’t important. The sooner she was done blowing a load in his ass, lubricating his innards with her spunk, the sooner the real show would begin.
Feeling the smaller unicorn begin to flare within him, Shining clamped down, milking his sister’s length with each upward stroke. His time with her had allowed him to recognize the subtle clues she gave off. Her hitched breathing, the chaotic humping, and slight twitching of her shaft, all the signs indicated the filly was a hair’s breadth from popping. Deciding to finish her off, so he could fully devote himself to the regal alicorn, he slammed his hips downward, hilting himself on his Twilight’s dong.
“Fuck,” Twilight wheezed, caught off guard by her brother’s coup de grâce. She must confess, the effeminate stallion had come a long way from being pitiably rutted in their living room, mewling like a whore while she claimed his ass. Now, the tables had been turned and Shining could get her off with practiced expertise. “That’s my BBBBF,” she thought to herself, watching as his pucker gulped down her entire load, expanding as each shot rocketed through her shaft to paint his interior.
“Oh my, you certainly know how to please a mare,” Celestia chuckled nervously, a few drops of sweat forming on her face after having watched Shining carnally execute his sister. Though she had every intention of having her way with his backside, she hadn’t expected to be so thoroughly aroused by this stallion. He was, in all ways but one, a stunning mare of imposing sensual prowess. “P...perhaps we should progress to my bedchamber,” she stammered, her resolve and poise beginning to crumble at the thought of mounting her partner.
Upon hearing the Celestia’s words, Shining reared his head back, allowing the painfully thick length of alicorn meat lodged in his throat to slip free. Gooey strands of pre-cum and saliva hung from his muzzle before the stallion mopped them away. He held up a hoof, coughing and catching his breath for a moment, giving the princess a moment’s pause. Regaining his composure, he locked eyes with the princess. “I...if I may,” he weakly stuttered, standing and dislodging Twilight’s shaft from his cum slick rump.
Celestia watched as the gorgeous stallion pressed a hoof to her chest, causing her to recline on her throne. Her eyes went wide, watching as Shining cautiously climbed atop her. Standing over her, and turning around, he presented his supple and cushiony rear to her while bracing his hind hooves on the armrests of the chair. With glacial speed, the stallion lowered himself, kissing the tip of her prodigious appendage with his puffy and well used tail hole.
“A princess,” Shining muttered, arching his back and bringing his face beside the princess’s while steadily applying more pressure to the bloated head of her cock, “should have a throne…” With those last words, he bore down, penetrating himself upon the alicorn. In that moment, the unicorn was undone by his hubris. Stretched beyond reason, he groaned, his efforts faltering at the enormous intrusion. He thought he could handle it but, in the face of a living goddess, his delusions of grandeur shattered outright.
Celestia chuckled as what little self restraint she had withered away. It was cute really, this stallion thinking that he could assert dominance over her. But, like any good pony who gets too full of themselves, Shining had to be taught a lesson. “Quite right, my good little mare. Please,” she warmly growled, her tone standing in utter contrast to her words, “have a seat.” Wrapping her forelegs around his shoulders, she pulled her mate downward while heaving her hips upward, impaling the entirety of her length within the unicorn in one smooth motion.
Something inside of Shining’s mind shattered at the act. Some part of him realized that there should be excruciating pain as his body was suddenly filled with something the size of one of his limbs, but all he felt was rapture. A steady stream of pre-cum leaked from his throbbing shaft as he sat like a statue on the princess’s lap. He looked down and his jaw went slack. His abdomen, already pre-lubricated with the copious amount of cum Twilight had dumped into him, distended outward as Celestia’s mighty cock pressed against his insides; its imprint unmistakable against the interior of his belly.
“Surprised?” the alabaster princess whispered, nibbling Shining’s ear. “We alicorns have several...unique gifts. Among which is the ability to make sure our mates are not only able to accommodate our size, but experience pure bliss as well,” she explained, bucking her hips and causing the stallion to squeal in delight to punctuate the point. “But,” she continued, smiling cheekily at her partner, “shouldn’t a princess pleasure her mate? After all, you wanted to sit upon the throne, my pretty little mare.”
Dredging every ounce of willpower he had, Shining raised his waist, removing several inches of the divine, meaty staff from himself before pounding back downward. Slowly, ever so slowly, he began to move, bouncing his backside up and down Celestia’s prick. He eased himself back, pressing his back to her chest while fucking himself upon her. The sensation was astounding, having something so immense rearranging his insides while, more importantly, fully giving himself to the glorious ruler of their land.
Celestia exhaled in contentment, placated by the stallion’s ministrations. “You know,” she said thoughtfully, rubbing Shining’s gut as the imprint of her shaft pistoned in and out of view, “I could very well make you a mare. You seem more than satisfied to service ones like myself and I’d love to be able to see you heavy with foal…” As she spoke, her gaze crept to his bobbing prick, watching as a few pitiable spurts of cum dribbled forth. Taking note of his reaction, she leaned in close. “You know, have some lucky stallion or dickmare fill your womb. Watching as your pregnancy begins to show, your breasts swelling as they fill with milk,” she breathed hotly, causing the stallion to pick up speed. “You just have to earn it…” she concluded.
Shining wasn’t sure if the princess knew about his deep seated desires, but her words were a siren’s song to his ears. As his penchant for worshiping dickmares had grown, so too had his desire to become true mare. Even though his body was that of a female’s, and his mind for that matter, his stallionhood had remained. He hadn’t even used it in the past few weeks, achieving orgasm through penetrative sex alone, fantasizing about what it would be like to be impregnated and carry a foal. As he continued rutting himself on the alicorn, he felt movement as Celestia began to thrust, slowly at first, but with increasing speed and strength.
“Yes,” Shining cried, throwing his head back, the crown slipping from his brow and clattering to the floor, “please, I beg you!” Any reservations he’d had were lost in the face of having his wish granted. All he could do was hope that the kindly princess was willing to oblige him.
Wrapping her forelegs around the unicorn’s hips, Celestia began pounding Shining’s ass in earnest. She could feel his interior contort and shift with every thrust as the twists and turns of his colon massaged her length. Her horn ignited, her magic lifting the stallion off of herself as she began to deep dick him. His head lolled, and legs went slack, as the princess’s colossal rod plumbed his depths. She knew no harm would come to him, due to her innate alicorn sorcery, and she sincerely hoped he was enjoying the experience as much as she was.
Able to do little else beyond letting effeminate whimpers and moans escape himself, Shining was ruthlessly fucked by the princess. He didn’t mind and, in truth, it was the most intense sexual ordeal of his life. Wearily rolling his face back to meet the alicorn’s, he attempted to clench down on her member, desperate for her seed to fill him. “Please,” he implored, tears of ecstasy streaking his face, “make me your mare.” The stallion’s humble request was answered as Celestia’s strokes magnified in power and quickness. She rutted him with everything she had, physically thrusting upward each time her magic brought him crashing down upon her. Her massive nuts slapped against his own inferior equipment, only adding to the intensity of the situation.
Celestia winced, her regal testicles beginning to retract as they prepared to deliver their load. The light around her horn gradually grew brighter and brighter, casting deep shadows over the floor and bathing the two ponies in brilliant force. In one final, powerful stroke, the princess hilted herself in the stallion. The head of her cock flared deep within the unicorn, locking itself in his bowels as her shaft throbbed violently. Biting down on his neck, she claimed him. Wave after wave of scalding seed coursed through her length as she erupted, each pulse of her prick sending nearly a pint of her spunk into her mate.
Shining’s eyes flew open as he felt the alicorn’s floodgates open. To call his response an orgasm would be a woeful understatement. The stallion came with every fiber of his being, every single sense overloading with pleasure as he was filled beyond reasoning with virile and magically imbued cum. Without realizing it, he screamed, howling to the heavens as his very soul struggled to endure the cataclysmic ecstasy he suffered through. Although he had no way of knowing it, the princess’s climax was ensuring his dream would come to fruition. His gut bloated as liters of cum surging through his innards, causing his belly to distend and sag at a slow but steady pace.
Twilight came as well, gleefully pleasuring herself while bearing witness to the most legendary sexual encounter she’d ever seen. She was sure that the memory of this day would stay with her for the rest of her life, especially given the fact that it would be the moment hailing the loss of her brother and birth of her sister. Looking up to Shining, she realized he’d gone comatose, limply sprawled on the alicorn, his eyes glazed over. Celestia, though still conscious, was covered in sweat, breathing heavily as she rode out her orgasm. Getting to her hooves, she slowly trotted over to the throne.
“The plug,” Celestia wheezed, noticing the filly approach. To assure Shining’s transformation would take root, her seed needed to be stay within him, it’s sorcerous power leaching into the stallion over the coming hours. The little purple unicorn did as instructed, fetching a small crystalline artifact from behind the throne. The princess grunted, lifting the debilitated pony off her length. With a wet pop, her member slid free from his gaping ass, a thick deluge of cum gushing forth before his hole was filled with the ensorceled stopper. The alicorn’s marecock, flopping free, steamed in the cool air of the open, thick gobbets of seed dripping from it to the polished floor. “Take him to the guest quarters and mind him for the night,” she instructed, passing Shining Armor to his sister, allowing the filly to levitate him closer to herself.
“Of course! Is there anything else I can do for you princess?” Twilight asked, always eager to please her mentor.
“Yes, tell the guards to signal our guest that the deed is done. I’m sure she’ll be delighted to know the events have been set in motion,” Celestia added, shakily sliding off the throne. Even though the experience had been sublime, she was dreadfully tired; the act of expelling such a large amount of magical energy, and the intense love making, had left her utterly drained. “I’ll be in my chambers if anypony needs me,” she muttered, shambling off towards her room to clean herself and get some well deserved rest.
Humming happily to herself, Twilight trotted towards the door, her brother floating beside her. Once she got him cleaned up and tucked in bed, she’d complete the second part of her task, seeking out the final element of their grand scheme.
Shining Armor slept like the dead, ferried away by his sibling to sleep. He had no way of knowing it, but tomorrow would signal the beginning of his new life...
