Chapter 1

Having seen herself to the Crystal Empire had been a breeze, her walk through the castle had been pleasant, and yet Celestia faltered once she finally reached her destination. She lingered just outside the Prince and Princess’ chamber, nervously fidgeting and straightening her gown, as she peered down at herself. Despite having looked forward to her visit for the better part of two months, she was suddenly filled with a heady cocktail of excitement and anxiety.

Trotting to her left, making use of one of the large windows sat in the tower’s wall, she looked herself over for the umpteenth time. She was no different than usual, having held the same figure for the past few decades, although she was still self conscious about her look. While she was significantly taller than most mares and even a good number of stallions, she was by no means a thin woman.

To put it simply, she was large in every sense of the word. Her prodigious chest, expansive backside, pillowy thighs, and plump belly gave her a rubenesque figure, beautiful in its own right, yet she hadn’t always been that way. Centuries of admittedly indulgent feasts and tending to her Empire, a job which had grown increasingly easy due to her sister’s return and the ascension of two new Princesses, had made her soft both literally and figuratively - nevertheless, she was a mare with needs.

She adjusted her top to expose just a touch more of her bounteous cleavage before stepping back to the door, drawing a breath, and slowly exhaling. There was no point in dallying, not for the least of which reasons being she was expected, so she put on her most charming smile and gave a sound knock. It was hardly the first time she’d paid Cadance and Shining a visit, but this was a special occasion.

The soft sound of footfalls from within was followed by the door clicking and opening, revealing the young Prince’s smiling face. “Celestia,” he began, stepping out and hugging her, “I’m glad you could make it!”

“We’ve been looking forward to seeing you,” Cadance added, idling just within the room.

“I…it’s nice to see you too,” Celestia murmured, raising and placing a hand on the stallion’s upper back.

Towering over the Prince, she peeked down and awkwardly smirked at him. Given the disparity of their sizes, the tip of his horn was practically nestled in the valley of her bosoms - a fact that never ceased to amuse her. Though both he and his wife were shorter than herself, his strength of character and self-assuredness, as well as several of his more subtle features, nearly made up for his comparably short stature.

“Please,” Cadance continued, swinging the door open and waving an arm, “come in.”

As Celestia peered at the Princess of Love, a thrilled shiver ran up her spine. While she’d gradually grown larger over the years, her young host had blossomed into a veritable icon of maternity. With a rounded belly, heavy chest, and generous tush, Cadance was mere months from her due date. The impending delivery of the couples’ foal would be a grand event, and one the pair had looked forward to for months on end, although it came with a catch; unwilling to risk either his wife or progeny’s health, the Prince hadn’t fully been able to address his stallionly needs.

Having demurely freed herself from Shining’s grasp, she stepped into the room and gave a small bow. Their chamber was just as she remembered it, spacious, comfortable, and with a king-sized bed sat to one side, yet it was what she couldn’t see that piqued her interest. Since the royal couple were dressed immaculately, much like herself, she was left to wonder what lurked beneath their formal-wear.

“So,” Shining began, kicking the door shut and sauntering over to his oversized guest, “tonight’s the big night ~ eh?”

Celestia nodded, her thrilled apprehension roaring back to the forefront, as he nonchalantly slipped a hand around her waist and caressed her rear. His very touch set her nerves alight, knowing all too well that he’d give her just what she wanted - still, she didn’t want to come across as too needy. Smiling to him and his wife in turn, she softly cleared her throat.

“I’m as r…ready as I’m going to be,” she sputtered, feeling her marehood clench within its dampened, silken confines. “I can’t thank you two enough for this.”

“No, thank you,” Cadance tittered, strolling behind and drawing her hands up the diarch’s back. “Shining hasn’t gotten any proper action in a while, so he’s been dying for this ~ haven’t you, honey?”

Rubbing the back of his neck, with a blush creeping into his cheeks, he grinned. “Y…yeah, I’d be lying if I said I wasn’t.”

Trotting around Celestia, the Princess of Love brazenly fondled her husband’s groin. “Please,” she cooed, “don’t be so modest. You’ve mentioned this visit no fewer than a dozen times over the last week!”

“It’s true,” he admitted, lifting his head and smiling up at the alabaster alicorn, “I was eager enough to have you come and spend an evening, but after hearing your request…”

Sensing herself starting to blush, Celestia reflexively ground her thighs together. “W…well I appreciate you two accommodating me. I couldn’t pick a better pair of ponies for such a task.”

“In that case,” Cadance purred, extending an arm and running her fingers up Celestia’s thigh, “how about we get things started. Shining, be a dear and go sit on the bed. Since we’re entertaining, perhaps our guest can give you a bit of a show.”

Celestia looked between the duo, caught off guard by the suggestion. She’d expected - well she hadn’t been exactly sure what she’d expected, but she wouldn’t have guessed things would kick off as soon as she’d arrived. As she clasped her hands before her chest, keenly aware of a bead of marish nectar gliding down her inner thigh, she watched the couple part.

Cadance strolled to the bedside, levitating a chair over to herself, while Shining eased himself down onto the foot of the bed. Like it or not, she was left standing in the center of the floor by her lonesome. In all her years, even during her impulsive youth, she’d always been a bit reserved, leaving her unprepared for the moment.

“Please don’t judge my underwear,” she began, reaching back and pawing for the zipper on her gown. “If I’d known you two were feeling voyeuristic, I would have dressed accordingly.”

Leaning back and bracing himself on one arm, Shining dismissively waved a hand. “Anything you’re wearing is just gilding the lily. Trust me, you’re fine.”

“If I’m being honest, I hope I get a body like yours,” Cadance murmured, watching the amazoness slip a shoulder strap free. “When did you stop growing?”

Pulling the dress down, revealing the black lace of her bra, Celestia kept her eyes on the floor. “I was around two-hundred, if I remember right, but it’s been a long time…”

She momentarily lifted her gaze and peered over at the younger Princess, wondering how big her fellow alicorn would get. Cadance was only in her late twenties, a mere fraction of her age, yet she’d gradually gotten larger over the years. The girl was already taller than her husband by a few inches and would only get taller as time went on, imbued by the power of her being and title.

Letting her dress go, allowing the garment to drift down her frame and fall to the floor, she reflexively held an arm over her breasts. She knew it was silly to try and cover herself, considering she wore her lingerie and because the couple had seen her nude on a number of occasions, but something about having the duo staring at her made her feel even more modest than normal. As she slowly turned away from her hosts, giving herself the slightest bit of comfort, she ignited her horn and unclasped her bra.

Though she wasn’t one to toot her own horn, she was particularly fond of her undergarments. Midnight black and traced with lace, her lingerie contrasted wondrously against her snow-white coat. Loosing her brassière and holding the article to her chest with one hand, she drew the panties down her hips and slowly bent forward.

It may have been a bit embarrassing to show off her rump so quickly, especially because her treacherous tail insisted on flagging, but it was better than seeing Shining and Cadance’s reaction to her impromptu strip-show. It was only when her panties drifted past her knees and down her calves, settling on the floor below, did she straighten up and turn to face her gracious, amorous hosts.

“That’s so hot…” Shining reverently whispered, eyeing the elder Princess’ groin.

The comment caused Celestia to go beet red and cover the heart-shaped tuft of prismatic hair on her crotch. “I…I thought it would make the night special.”

A movement below his amused face caught her eye, bringing her attention to what she’d been doing while facing away. At some point, likely inspired by her show, he’d unzipped his pants and freed his not-so-little soldier. Though Shining wasn’t much taller than most stallions, there was a reason other than his charming personality and athletic body that Cadance had married him. There was no tactful way to put it - he sported a downright monstrous endowment.

The sight of his stallionhood caused her heart to skip a beat, knowing all too well what wonders his gargantuan length could deliver. She’d bedded a number of ponies from all tribes over the years, yet not a single one could compare to Shining in either length or girth. Her nipples went erect, her mouth began to water, and her sex slavered uncontrollably, while her mind wandered into lecherous waters.

She’d been a bit surprised when Cadance had asked her to be their third several years ago, shortly after the nearly disastrous wedding at the Canterlot castle, yet she’d sheepishly obliged - not purely because she’d been weathering a protracted dry-spell, but because the Princess of Love had regaled her with tales of his profound package. Ever since that first heavenly night, she’d found herself looking forward to their semi-frequent trysts.

“You’re staring,” Shining softly tutted, clutching and languidly stroking himself. “How about you come over here and get a closer look…”

Before she realized what she was doing, Celestia took a step forward, then a second and a third, until she was looming over the seated stud. Heaven help her, she really was hopeless. Until that evening, she’d always restrained herself from asking for their affection, although she hadn’t requested their services purely to indulge her lust - no, she wanted something much more significant.

As she gradually sank to her knees between his parted legs, her bosoms coming to rest on her thighs, she reached out with a trembling hand. This - this was what she needed, the perfect tool to give her an heir. Having watched Cadance grow gravid over the passing months had been hard enough to endure, but her heat, a cycle which only struck her once a decade, had been the final nail in her coffin. If one of her protegees could start a family at such a tender age, it was high time she had a foal of her own.

Save for her panting breaths and the steady drip of juices from her marehood, the room was deathly silent as she grasped his cock. Hot and heavy, sheathed in velvety skin, his stallionhood sang to her - practically begging for her attention. Unable to control herself, only having to dip her head slightly, she closed her eyes, angled his shaft toward her face, and kissed the tip of his length.

As if feeling his endowment wasn’t arousing enough, the smell - ancestors forgive her, the scent of his virile musk was intoxicating. She had no doubt that he bathed regularly, but his natural aroma stimulated the deepest, most primal portions of her mind. Spurred by her impulses and baser instincts, she wrapped her full, pouting lips around the head of his cock and dipped her head.

The sight and bouquet of his equipment would have been enough to arouse or intimidate any mare, yet those were far from the only wonders Shining’s stallionhood held. The taste of his flesh, tinged with sweat from what had undoubtedly been a full day’s work, danced over her taste buds. She shifted slightly, allowing herself to better suck him off, and felt her bosoms slide against his upper legs.

Though fully intended to get him warmed up, the weight of her hanging bust gave her an idea. The sheer enormity of his stallionhood, paired with her imposing size, would easily let her make use of one of her more formidable assets. Pausing ever so briefly, she clutched one breast in each hand, shuffled forward, nearly his entire length in her cleavage.

Even taking her height into account, her rack and rear were spectacularly large, proportionally bigger than they had any right to be, which was both a blessing and a curse. On one hand, her measurements made getting garments a bit of a hassle - on the other, she couldn’t deny that she took no small amount of pride in the attention they garnered. She smiled around the tip of his dick and peered up at his face, relishing his awestruck expression as she rocked her chest forward and back.

She couldn’t speak for other mares, but she absolutely adored pleasing a stallion. The power she wielded, knowing the deadly combination of her appeal and curves to get somebody off, was exhilarating to a fault. As she placed her elbows to either side of her bust, ensuring his shaft was firmly lodged betwixt her tits, she forced her head down and sheathed the exposed portion of his shaft in her snout.

“Mmmmmm,” a familiar voice sensually hummed, before something - no, a pair of soft somethings pressed against her back. “I hope mine get as big as yours someday…”

Without needing to look back, she realized Cadance had seen fit to join them - not like she could blame the girl. The Princess of Love had earned her title, being very open with her relationship, and was a paragon of sexuality. Continuing undeterred, moving her hands just enough to tweak and twist her nipples, she shivered as the youthful alicorn’s hand slipped down her back, under her ass, and to her drooling nethers.

While she hadn’t anticipated such a deliciously depraved turn, she wasn’t about to complain about the attention. It would only be a matter of time until the opening act passed, but there was no need to rush; by the time the night was out, she felt certain that her foal-factory would finally be put to use. She groaned around Shining’s stallionhood, her eyelids fluttering as a finger glided over her winking, engorged clit, while she bobbed her head and coated his shaft with saliva.

She could nearly imagine his view, staring down at her while she hit him with her tit-fuck and blowjob combo, elevating her arousal. As self-conscious as she normally was, moments like this stroked her ego and bolstered her pride immeasurably. Had she been any other mare, it would have been impossible for her to service every inch of his awe-inspiring length - fortunately for her, that wasn’t the case.

With every second that passed, the fires of her lust burned hotter and brighter. Her marehood ached, her nipples were practically hard enough to cut glass, and her heart thundered in her chest, while her mind grew fogged. Even for an ancient Princess such as herself, there was only so much she could endure. It wasn’t until Cadance shimmied over to her side and slipped two fingers into her depths, rubbing her g-spot and causing her to whimper, did she reach her breaking point.

Withdrawing with a soft pop, she licked her lips and ravenously looked between the pair. “May I?”

Cadance closed her eyes and bowed her head, politely holding a hand to her milk-laden bust. “You may.”

In spite of having traveled to the Crystal Empire purely to spend a passionate evening with the royal couple, Celestia would be remiss for not asking permission to progress. As she backed away and pushed herself up, her slickened tits swaying as she stood, he craned his head and gazed up at her. He was a fine stallion, caring to a fault and an immaculate lover, although she had no intention of letting him have all the fun.

“Precious Shining,” she sighed, bending at the waist placing her hands on his shoulders, “you have no idea how much I’ve been looking forward to this…”

As he was steadily driven onto his back, unable to stop her even if he tried, he glanced over to his wife. “Well I - Mmmph?!?”

Celestia couldn’t have cared less about what he’d been going to say. She was the oldest Princess in the land, she had selflessly tended to Equestria for millennia, and now she was going to make her dreams a reality. Quite literally smothering him with her breasts, leaving only the tip of his horn and a shock of his sapphire-blue mane peeking out from her between her teats, she draped herself atop him and rested a knee on the mattress beside his hip.

She knew from past experience that he was fond of her rack. The way she’d caught him peeking at her chest, even before he’d gotten married, and how he’d almost always fondle and grope her breasts during their more intimate exchanges said more than words ever could, so she saw no harm in catering to his interests. If he was going to sire a foal with her, the least she could do would be to make sure the moment was memorable.

“Hmmhmmhmm ~” she quietly snickered, swinging her shoulders from side to side and all but crushing his face in her bust. “Imagine how much larger they’ll be once I start lactating.”

Her comment must have stricken a nerve, because he wriggled free and excitedly peered up at her. “I could help you milk them - t…that is, if you’re ok with it.”

A predatory grin split her muzzle, as she reared back and pressed a nipple to his lips. “I’d expect it - after all, if you’re going to give me a foal, you’ll need to ensure my big, surely leaking breasts don’t get too full or tender.”

His hands shot to her bosoms, kneading and gently squeezing her supple flesh, as he latched onto her teat and suckled the delicate bud of flesh. The sensation of being nursed on spoke to her deepest, most profound desires, tingeing her passion with maternal needs she’d yet to fulfill. Taking care to keep her chest where it was, slipping a hand under his head to pull him into her breast, she seated herself on his lap and ground her aching sex against his shaft.

She hadn’t been lying to him. Once she had a bun in her oven, it would only be a matter of time until her mountainous mammaries began doing what they were made to do - as such, given that mares typically began making milk well-before delivering, she would rely on Shining to ease the burden of her dairy production. With her plump lower lips gliding over his length, pinning his cock between his abdomen and her groin, her ambitions got the better of her.

Feeling the girthy medial ring of his stallionhood nudge her clit, something clicked within her. Enjoying herself was all well and good - heck, she’d done so with the couple on numerous occasions, but she wasn’t there merely to slake her darnal desires. Crawling up his body and pulling her breast from his suckling mouth, she flexed her legs and allowed his length to spring between her between her ample buns.

“I trust these are nice and full for me?” she whispered, reaching back and gingerly running a finger over his ripe, furry balls.

As she flexed her legs and raised her waist, Cadence stepped behind her, grabbed Shining’s length, and brought its head to her entrance. “With a week of abstinence and that virility spell I put on him earlier? Yeah, I’d say he’s more than ready.”

There were hundreds of things she could have done to prolong the moment, but Celestia could control herself no longer. She wanted, no - needed to feel him inside her. As she lowered her hips, savoring the momentary sensation of his nearly fist-sized tip struggling to penetrate her, she was granted her wish. Her eyes rolled back, she gnawed her lip, and a stifled whimper escaped her, as his enormous endowment slipped into her velvety confines.

Every detail, from the veins along his shaft to the ridged head, felt incredible as his stallionhood plunged deeper and deeper. Tremendous though she was, he was more than equipped to fill her in all the right ways. Lower and lower, inch by inch, she continued her descent until she was seated fully on his lap. Like a lock and key made for one another, the tip of his shaft kissed her starving womb.

While she would have liked to look at him, she wanted to bask in the sense of fullness he afforded. Outside of a very small handful of occasions involving dragons or yaks, there wasn’t a creature in the land that had been able to satiate her like Shining. Ensuring he would have a picturesque view of her body, she leaned back, placed her hands behind her head, and triumphantly wiggled her hips.

“Like what you see?” she mused, her heaving bosoms wobbling with her every move.

Utterly entranced by the sight of her, Shining extended his arms and gingerly grabbed her waist. The look in his eyes told her everything she needed to know - he wanted this just as badly as she did. Planting his feet on the floor, he bucked his hips and drove her upward. He may have been small compared to her, but years of hard work and training gave him the physical strength to handle her with relative ease.

With her hair standing on end, a bolt of pleasure coursing through her, she shuddered. “Yes…”

His thrust was the straw that broke the camel’s back, spurring her to action. Raising her behind and freeing the base of his length, she slammed herself down against him. If there was a more perfect way to start things off than riding him, she couldn’t think of it. With glacial speed, warring against her urge to fuck herself silly on him, she began bouncing.

He sat up and gave her flank a playful smack, his eyes darting between her breasts, face, and her nethers, as his smile broadened. “I don’t think I’ll ever get tired of - H…Hey!”

“Mind if I butt in,” Cadance tittered, her turquoise aura forcing him down into a supine position.

Celestia peeked out and watched as the mare casually crawled onto the bed and swung a leg over her husband’s head. She certainly wasn’t opposed to the young Princess getting involved - in fact, she’d secretly hoped for it. As much as she enjoyed the attention of a stallion alone, there was an undeniable joy to sharing a erotic moments with a mare.

“That’s enough talking out of you,” Cadance added, muffling the stallion with her thighs and marehood. “And you,” she continued, brazenly twisting and pulling on her guest’s nipples, “come here…”

Finding herself sorcerously dragged forward, Celesta was pulled into a deep, passionate kiss. Wholly of its own volition, her body began to move with increasing speed. The tongue in her muzzle, the medial ring grinding against her g-spot, the way his cock-head battered against her cervix - they were all perfect and left nothing to be desired. Before she realized it, she was fervently screwing herself on the stud while heatedly making out with one of her most trusted friends.

Slowly, almost insidiously, she lost herself to her welling bliss. Her grasp of time grew tenuous, as she savored the couple’s love. She loved Shining and Cadance more than almost anyone, so much so that they were all but paramours, and she would soon receive the greatest gift she could ever receive from them. Moving in tune with the stud beneath her, plunging down to meet his every thrust, she was shaken from her rapturous stupor by an unmistakable sensation.

“W…wait,” she bleated, bringing the affair to an abrupt halt.

It almost pained her to do it, but she ponderously rose and unsheathed Shining’s slickened, throbbing length. His stallionhood throbbed with each beat of his heart, its head having swelled slightly since when they’d first begun, and she knew his time was close. While there was nothing wrong with riding him until he peaked, she wanted the final moment to be perfect.

She cast herself to the side, rolling to her back with her tush resting on the very edge of the sofa, and obscenely splayed her legs. “Like this, p…please…”

Grinning to herself, Cadance unseated herself from her husband’s face and allowed Shining to sit up. “You heard her, Honey.”

Shining’s eyes, wide and wild, spoke to his rut-lust. He wouldn’t have lasted more than another minute, had she stayed atop him, so he scrambled from the bed, turned to face her, and guided her knees up and onto his shoulders. As he drove his hips forward, jackhammering into her with reckless abandon, she howled and thrashed on the sheets.

“It won’t be long now,” Cadance whispered, creeping to her side and kissing the nipple on her left tit.

“I - Mmmmmph!” Celestia’s response fell into a groan, then a wail of delight, as she was driven to the brink.

Forcing herself to open her eyes and gaze down at him, she felt the breath hitch in her throat. The sight of his body, well-toned and slickened with sweat, as he plowed her like a field in spring was the sort of thing fillies would secretly get off to at night, and she was not immune to his masculine wiles. Cadance hummed around her teat and reached out and her unmolested nipple, driving her that much closer to the edge.

Her age, her title, the millennia of experiences she’d had - none of them meant a thing in that moment. At the very core of her being, she was a mare - a mare who desperately pined to embrace her maternal potential and carry on her bloodline. It was only through pure willpower alone that she was able to lift her legs from his shoulders, fully intent to lock her ankles around his hips, yet Shining had other plans.

Before she could trap him in a leg-lock, he grabbed her ankles, leaned forward, and drove her legs to either side of her head. Though Cadance darted back and out of the way, she shot forward as soon as he had her pinned. The turn of events was unprecedented, worthy of treason, but the ecstasy which he delivered because of it - stars above, the ecstasy was worth more than a pardon.

The rhythmic drumbeat of their colliding bodies, paired with his throaty grunts and her whorish moans, made for a hedonistic symphony - one which rang in her ears. Even if she’d wanted to, she wouldn’t have been able to get away. Her arms were trapped under her legs, she could scarcely think, and the sensation of his flaring cock hammering against her inner gate were incredible beyond words, although it was her aspirations which ultimately did her in.

Deep within her was a fertile egg waiting for Shining’s essence, and that egg would soon develop into her progeny. She’d carry her son or daughter for months on end, her body nourishing and caring for them until the time came, and then they’d enter the world and greet her. The onslaught of joy she felt from knowing her purpose would soon be fulfilled did her in, causing her to throw her head back and bray to the heavens.

Nectar gushed from her spasming marehood, her orgasmic howl echoed throughout the chamber, and every muscle about her frame trembled uncontrollably, as she was rocked with the most intense climax of her life, yet Shining didn’t slow - if anything, he fucked her harder and faster than ever. Fighting through the haze of her bliss, doing everything she could to remain conscious, she was wholly unprepared for his final moments. With an unstoppable thrust, hilting himself and stuffing the tip of his stallionhood directly into her eager womb, he came.

Each pulse of his length sent a shot of thick, scalding essence into her, causing her climax to redouble. It was happening, the moment she’d dreamt of for ages, and she was going to remember it until the very last day she walked Equestria. His seed flooded her depths, bathing her interior with a single-minded purpose to bear fruit, while the world closed in around her. She heaved air into her chest, uncaring that the stud had released her legs and was laying atop her, and stared blankly up at the ceiling.

“You’re going to be so beautiful,” Cadance whispered, shifting over and kissing her cheek.

On a shaky arm, Shining pushed himself up and stroked his cheek against the diarch’s bosoms. “You really are.”

Celestia trembled and gave a small nod, only vaguely aware of what they’d said. She’d done it - after waiting so long, fantasizing so many times about this moment, she’d finally done it. As her rapture was gradually replaced by a euphoria and contentment like she’d never known, tears of joy streamed down her face. The road ahead of her was going to be long, and she was certain that motherhood would have its challenges, but any struggles she faced would be worth it. Draping one arm on Cadance and the other on Shining, she succumbed to her exhaustion and fell into a deep, restful slumber.

Chapter 2

Celestia stared down at her plate, spying the crumbs and streaks of maple syrup which remained on the porcelain, and scrunched her snout. Breakfast had consisted of two scones, a short stack of pancakes, sunny-side up eggs, toast, a cheese danish, and a cup of coffee - even after downing the sizable meal, she was tempted to lick the remaining syrup clean. With a petulant huff, telling herself she didn’t need it, she levitated the small, emptied platter over to her bedside table, gave a small heave, and got to her feet.

Refusing to bow down to her hunger served a dual purpose. For starters, she honestly didn’t need to eat anything else that morning - secondly and more prudently, she had to prepare for company. Strutting across her chamber and toward the boudoir, a movement to her side caught her eye. She stopped and turned, facing the standing mirror sitting beside her vanity, while a coy smile split her features.

She’d spent years being self-conscious about her weight, worrying that ponies would think less of her for putting on pounds as she’d gotten older, yet that time had come to an end. As paradoxical as it was, getting pregnant and gaining an inordinate amount of weight had uplifted her confidence into the stratosphere. Enwrapt by her reflection, grinning from ear to ear, she shifted in place, placed a hand behind her head, and struck a seductive pose.

Her chest had always been large, dwarfing even the bustiest mares by miles, but they’d grown considerably over the last two months in particular. While felt her diet or lack thereof had contributed to the size of her rack, the main cause was as evident as the blazing sun on a cloudless day. Milk weakly dribbled from each of her nipples, blending in with the white of her coat, and streamed down her breasts and onto her belly.

Ponies had likened her to a god before, an embodiment of divinity given equine form, but it wasn’t until she’d entered the final months of her pregnancy that she’d given the talk any credence. Like the incarnation of a fertility deity, she was beautiful and larger than life. Each teat was bigger than a beach ball and could produce nearly a gallon of milk every day, her abdomen was so large that she’d long since lost her ability to see her toes, and there wasn’t a seat in the land that could handle her absolute avalanche of an ass.

She slowly wheeled around, peeking over her shoulder and keeping her eyes glued on the mirror. Her bust, once her most potent amorous asset, had been overtaken by her nearly wagon-sized tush. Each doughy bun on her behemoth backside was enough to take up a chair by itself, making public outings a bit of an arduous affair - not like that was too much of an issue, considering she’d spent most of her pregnancy lavishing in the comforts of her keep.

Unable to control herself, she walked away from her reflection, watching the twin mountains of her rump hypnotically glide past one another, before wheeling around and running her hands over her rack. The mere touch of her slender digits was enough to evoke a small fountain of milk from her teats, rivulets of the nutritious stream spraying onto the floor beneath her. She couldn’t have cared less about the mess she was making, having memorized the spellwork necessary to clean up her all too common dairy faux pas, although it did tickle a different part of her mind.

Glancing over to her bed, she momentarily considered distracting herself with a bit of relief. Dealing with the gawking, oftentimes openly amorous looks from castle staff and regal visitors was easy to deal with, her preternatural strength allowed her to move about without much trouble whatsoever, and she wasn’t terribly bothered that her wardrobe had been reduced to little more than robes and togas - those were all things she could deal with easily enough. The real source of her troubles, aside from her bottomless appetite, was how her libido had gone through the roof!

She’d read that expectant mares often weathered hormonal changes, growing irate at trivial things or getting melancholic at the drop of a hat, but she had not been prepared to deal with a hyperactive sex drive. As if being in a near-persistent state of arousal wasn’t harrowing enough, it was like her sensitivity to everything had increased by an order of magnitude. The brush of fabric against her teats gave her shivers, the thought of a stallion was enough to drench her panties, and even the simple act of dressing herself would often lead to an impromptu, wholly self-indulgent masturbatory session!

Only eventually realizing what she was doing, she tore her hands off her chest and glowered at her reflection. Had it been any other day, she could have spared half an hour to rub herself into a quivering, squirting mess - regrettably, that wasn’t the case. As she marched into her bathroom, her hips brushing against the door frame and threatening to halt her progress, she did her damnedest to tame the horny beast that was her subconscious - after all, it would get what it wanted soon enough.

She stepped into her tub and magically set the water to warm, leaving the shower curtain undrawn. Like most things in and around her chamber, the basin in which she stood had been modified to accommodate her generous size. Doorways had been widened, reinforced furniture made, and several portions of the castle had been renovated for her - nevertheless, unless her little one came into the world soon, there’d likely need to be additional work done.

With a contented sigh, hovering a bottle of body wash and a loofah over to herself, she squeezed the liquid soap over her shoulders, belly, and bust. It was an odd time of day to shower, and she’d had one after waking up that morning, but it wasn’t without reason. Though she had no official work for the day ahead, having toiled long into the night before to get things done, she had a very, very important meeting she had to look her best for.

In a matter of minutes, she’d showered, rinsed herself off, and instantaneously dried herself using her magic, before donning a robe and trotting back into her chamber. As she stepped before her vanity and reached for her makeup, intent to accentuate her beauty with a touch of lipstick and blush, a sound from outside caught her ear. Looking over to the exit, wondering who was outside, she held her breath.

Knock Knock Knock-Knock Knock

“J…just a moment!” she called, her mind racing.

There were only two ponies on the whole of Equestria who had such a distinctive knock, so she immediately knew who lingered just beyond her door. She had no doubt that Shining and Cadance had arrived, even if they were slightly early, which left her at an impasse. As she straightened up, taking a step over to see her guests in, she glanced at her closet.

“I’m coming,” she affirmed, shaking her head and reining herself in. The last thing she wanted was to come off as too needy, so she decided to hold off on the little surprise she’d prepared, if only for the time being. Crossing to and throwing the door open, with her robe failing to conceal most of her bounteous bosoms and belly, she smiled out at her visitors. “Shining, Cadance, it’s so good to see you!”

The young Princess and Prince were just as charming and beautiful as ever. Though Shining didn’t look much different than he usually did, his wife was another story. Cadance had delivered Flurry Heart into the world nearly two months prior, but she’d retained most of the weight she’d gained over her pregnancy. The mare’s chest, rump, tummy, and thighs were still pleasantly plump, elevating her having a supermodel’s look to that of a very curvy MILF.

Shining smiled broadly as his eyes wandered up and down her titanic figure. “Nice to see yo-”

“Cele!” Cadance bleated, leaping forward and trying her best to hug the enlarged Princess. “It feels like it’s been forever.”

Sideling past the embracing pair, Shining closed the door and chuckled to himself. “Two weeks is hardly forever - that said…” he trailed off, gazing longingly at her rump.

Celestia hugged the young alicorn with one arm, but her attention lay almost solely on the stud beside her. “That said what?”

“You’re just - uh -” he faltered, his cheeks darkening. “It just seems like you get bigger every time we see you.”

“And that’s a bad thing?” Celestia countered, releasing the nubile mare and turning to face him. “It’s not like I’ve heard any complaints from you about my size,” she continued, closing in on and towering over him.

He glanced back and forth from her prodigious rack and her face, his grin wavering. “Oh n…no - it’s not a b…bad thing at - Hmmff!”

“Much better,” the expectant diarch sighed, leaning in and entombing his entire head in her cleavage. “He’s so cute when he’s trying to be modest.”

“He really is,” Cadance tittered, walking over to join them. “And I bet he’s - yup, he’s rock hard,” she continued, shamelessly grabbing his crotch.

Instantly releasing him and stepping back, Celestia peered down at his groin. Sure enough, held firmly in Cadance’s grasp, the imprint of Shining’s length was as plain to see as the light of day. Trapped within the confines of his slacks, snaking down nearly to his knee, the colossal swell fanned the flames of her lust and sent lecherous thoughts parading about in her head. As the Princess of Love squeezed and affectionately ran her hand over his clothed stallionhood, she peeked back at her wardrobe.

“E…excuse me one moment,” she blurted, wheeling around and dashing across the room.

On the off chance that either of her guests took issue with her sudden and admittedly abrupt absence, she could deal with it later - for the time being, her impulsive purchase and the chance to show it off took precedence. Dashing to and into her closet, slamming the door closed behind herself, she flicked the light switch and crossed to the very back of the small chamber. Her wardrobe was, like her suite, large enough to accommodate her plus-sized needs. She threw her arms back, allowing her robe to slip from her frame, as she hovered a small parcel over to herself.

She’d never been one to spend exorbitant amounts of money on herself, especially when it came to garments or jewelry, although there were rare exceptions. The article she’d purchased for herself was exceptionally salacious and wickedly fetishistic, but she’d fallen in love with it from the moment she laid eyes upon it. Her rotund size and prolific breasts had grown on her, literally and figuratively, so she couldn’t help but buy something that showed them off in a delightfully provocative manner.

It was only due to having donned the garment nearly a dozen times, mostly for practice but purely out of self-amusement, that she was able to slide into it without trouble. Adjusting the shoulder straps and the length of fabric nestled in the crack of her ass, she spun around and inspected herself in the mirror at the far end of her closet. Everything was ready, her guests were doubtlessly wondering why she’d rushed off, and she looked exquisitely slutty - it was show time.

Lingering at the far end of her wardrobe, she sorcerously opened the door, broke into a full strut, and sauntered out into her room. It was only by some miracle that the outfit stayed on, given how her breasts swung and bounced with her every step, but it managed to remain in place as she burst into view. She only stopped when she reached the center of the floor, holding her head high with a smug smile plastered on her muzzle, and expectantly looked over at her visitors.

The look on Shining and Cadance’s faces was priceless. The young Princess’ eyes were wide, her nipples nearly poked through the top of her dress, and she was left speechless, but her husband was a different matter entirely. With his jaw nearly on the floor, and his slacks threatening to tear from his struggling stallionhood, the virile stud seemed like he was on the brink of passing out - that or pouncing on his host like a starved beast.

“Nothing to say?” Celestia quipped, hefting her bosoms with a combination of her hands and magic.

She squeezed her teats and sent milk showering over the carpet at the stunned couple’s feet, as she suppressed a giggle and peeked down at herself. While she’d never exactly planned to buy a cow-print sling bikini, she’d been smitten with and instantly purchased the swimwear as soon as she’d spotted it in a magazine. The fabric of the bikini barely covered anything, clinging tightly to her crotch and failing to conceal her almost dinner plate sized areola, and she may as well have been naked, but it was comfortable, naughty, and just looked darn good on her.

Her fingers ran over her bust and around her engorged nipples, circling the delicate buds of leaking flesh, as she looked between the stricken pair. “I apologize that we don’t have a barn to play around in, but I don’t believe the Apple family would be too receptive of such a depraved proposal.”

“I’ll be right back!” Cadance chirped. With a flash of light and a pop of displaced air, she was gone, whisked away through the ether to heaven knows where, leaving Celestia and her husband to stare blankly at the area she’d been standing in.

Turning to face his host, closing his slackened jaw, Shining cleared his throat. “Before you ask, no, I have no idea what that was about.”

Celestia wasn’t sure what to think of the unforeseen turn of events. Cadance hadn’t seemed upset in the slightest, but she hadn’t given the slightest clue as to where she’d gone or why she’d left in such a hurry. At a total loss, hoping she hadn’t done anything to offend the young mare, she was stunned when Shining closed the gap between them and stroked her thigh.

“I have to say, that outfit looks amazing on you,” he hummed, his fingers drifting up toward her groin. “It’s almost like you’re trying to get us worked up…”

“I…I would never - Nnnnph,” she groaned, feeling his digits tease the succulent mount of her marehood.

He cocked his head and paused, staring intently at her face. “You’d never what? Never dress up like a big, lewd cow to try and get a little action?”

Seconds from replying, yet not knowing what to say, she moaned when he grabbed and started rubbing her sopping-wet nethers. If he’d had any question as to how worked up she was or what her motives were for donning something so sinful, she had no doubt that he quickly figured out where her intentions for him and his wife lie. Bucking into his hand, sending his fingers sliding closer to her entrance, she bit her bottom lip.

“You know,” he mused, a knowing, impish smirk creeping across his snout, “a good cow would behave and let herself be milked - I mean, if she wanted a big, meaty reward.” Withdrawing and inching back, he ran his hand over the imprint of his turgid shaft. “You’re a good cow ~ aren’t you?”

By the pillars, she had not been prepared for him to be so forward - then again, she was the one who’d strutted out looking like a whorish bovine. All but wrapping her arms around her bosoms, her hands clasped at the base of her cleavage, she gave a slightly too enthusiastic nod. Regardless of where Cadance had run off to or how long she’d be gone, she and her lone, magnificently well-hung visitor were more than a little turned on and had nothing to do but entertain one another.

“Aren’t you?” he repeated, reaching up and grabbing her right nipple.

A wave of pleasure crashed over her, causing her to gasp. “Y…yes!”

“Ah ah ~” he tutted, kneading and gently pulling on her teat, coating his hand in milk in the process, “I don’t remember cows being able to talk.”

Her mind raced for a split second, her excitement mingling with apprehension, until understanding hit her like a ton of bricks. She’d presented herself like an animal, bestial and yearning for carnal affection, so she’d have to play the part. With amorous juices trailing down her legs, leaking milk like a broken faucet, and her knees threatening to buckle, she drew a breath and steadied herself.

“Moooooo!” she groaned, blood surging into her cheeks as she made the noise.

“Good girl,” he murmured, thrusting his hand back between her thighs. “I knew you were a good cow.”

She trembled as he pulled her bikini aside and graced the bare flesh of her sex, feeling herself winking in response to his touch. In spite of being ancient in comparison to most creatures that walked the land, the sensation of being aroused always had and likely always would take a toll on her. Facing villains, demigods of chaos, and threats to her Empire were easy - attempting to endure a fine stallion’s advances were less so.

He teased her entrance, the tips of two fingers sliding forward and back between her lower lips, and scanned the area by her bed. “I know you have a bucket around here.”

“M…moo!” and animatedly replied, pointing to her closet.

Following the line of her finger, Shining grinned, turned toward her wardrobe, and soundly smacked her enormous backside. “Go get yourself comfortable. I feel like this is going to be a long milking session.”

Her heart skipped a beat, as she fidgeted and wheeled around. She wasn’t sure exactly how he’d like her to be positioned, but she was stricken with inspiration. Crossing to her vanity, she leaned forward, placed her elbows against the burnished wooden surface, and relaxed. Each gargantuan tit hung beneath her, coming to within an inch of the floor, while her belly rested on the soft carpet below. It was a mere coincidence that her backside was perfectly angled toward her closet, meaning he’d have a picturesque view of her rump as soon as he emerged, yet that would hardly be an issue.

With her legs braced and tail swung to the side, she peeked back expectantly. Sure enough, after only a few seconds, he emerged from her closet, but there was a problem. He’d found her milk bucket, a novel item she’d bought while first attempting to milk herself, but he’d also found something else. Held by its handle in his right hand was the milking machine she’d taken to using every morning, midday, and evening.

“Oh you poor thing,” he mockingly lamented, holding the contraption aloft. “Don’t worry, your beefy stud is here to help.”

There were few moments over the last century or so when she could honestly say she’d been giddy, but be darned if this wasn’t one of them. Her blood ran hot, her marehood dripped to the floor, and she could practically stand still, as he walked over and knelt beside her. Flicking a switch on the machine, setting it to softly hum, he brought two of the siphoning suction cups to her pendulous teats.

Heedless to or ignoring her thrilled shiver, he patted her flank. “Atta girl - now hold still.”

He shuffled around and behind her, out of view, but she quickly deduced what he was planning. The sensation of what could only be a tongue, warm and wet, crawling up her thigh was exhilarating, equal parts tormentous and arousing, while he gradually made his way up to her nethers. With all the speed of a glacier, he continued his ascent until the top of his snout came to rest against the cleft of her ass.

“M…moo - Oh f - MOOO!” she brayed as he buried his face in her tush and plunged his tongue into her quivering depths.

Though they’d shared numerous passionate bouts with one another, it was a relatively rare event that he warmed her up with his mouth - normally Cadance beat him to it. His hands ran up and down the back of her thighs, and he hummed into her, as he alternated his focus between her silken confines and her bulging clit. Between the oral and the cups ceaselessly tugging on her teats, drawing a continual stream of milk from her heavy bosoms, she couldn’t have been happier with the development.

As disgraceful as it was, her thoughts drifted to a particularly taboo fantasy. Had she not been a Princess, she could see herself living a quaint life on a farm with a dutiful husband, a garden, some livestock, and plenty of children to keep her busy. The idea of being little more than a housewife and broodmare to a hardworking, hunky stud of a husband was beyond stimulating. Barefoot and pregnant, essentially a foal-factory on feet, her only duties would be to carry on her lover’s bloodline, raise the children, and ensure her family was happy, healthy, and very well fed.

Shifting behind her, bringing one hand to her groin, he brought his thumb to her clit. “Don’t be scared to be loud; I want everyone in the castle to hear my big, sexy mother-to-be enjoying herself.”

With her licentious urges getting the better of her, she swung her hips back and nearly sheathed his snout in her snatch. It hadn’t been the first time she’d muzzled him with her marehood, and she highly doubted it would be the last, so he knew he wasn’t all too bothered with the development. As odd as it was to say, his snout wasn’t nearly as big as the monster he was packing in his pants.

The move caused him to start, his motions drawing to an abrupt halt, but he didn’t stay that way for long. With renewed zeal, he held her tight and drove his face deeper, questing for her g-spot while fervently rubbing her clit with his thumb. Most stallions would have been taken aback by such a development, but not Shining - not having grown accustomed to satiating not one but two alicorns with health sex drives.

A sudden breeze and the familiar sound of discharged magic shook her from her fantasy, drawing her eye to the side. Though Cadance had only been gone for a matter of minutes, she wouldn’t have minded if the mare had taken her time. Watching the Princess lift her hands, seeing why her guest had left them, she swallowed hard.

“Nice to see you started without me,” Cadance playfully huffed, prancing over to the diarch. “Here you go, Bessy.”

As a pair of novelty horns were placed on her head, and a novelty cow bell placed around her neck, Celestia uneasily grinned. Even if Shining’s face hadn’t been planted squarely in her rump, she would have been powerless to stop her friend from playfully adorning her with the items - not that she was terribly bothered. She held herself steady, trying to decide if she should break character and say something or continue basking in the pleasure of being serviced by the stud, as Cadance sank into a deep squat beside her.

Patting the spectacularly gravid Princess’ abdomen, Cadance peered to her host’s face. “Push yourself up just a little bit…”

Celestia unquestioningly did as she’d been asked, though she had no idea what she was in for. As she studied the girl, watching her turn off and remove the suctioning cups from her tits, she softly whimpered. It wasn’t until the mare pulled the bucket over, situating it beneath her chest, that she had the faintest inkling of what was about to happen.

“Did you make her moo already?” Cadance flippantly asked, grabbing and squeezing the pair of udder-like tits hanging before her.

Shining withdrew and leaned to the side, peering over at his wife. “Sure did. Come on, hot stuff, let her hear it.”

The slight sting of his spontaneous smack to her rear mingled with her bliss, prompting Celestia to unleash an utterly whorish moo. There she was, one of the most illustrious ponies in the land, dressed and mooing like a rut-crazed cow - it was debased, she should have been embarrassed beyond all reasoning, yet the taboo excitement of it all was beyond reproach. Nobody would ever know that the demure, genteel Princess of the Day was a hopeless harlot behind closed doors, and she meant to keep it that way.

Another pop of discharged magic brought her attention behind herself, as Shining gradually rose to his full height. One of the only unfortunate things about being a veritable giant was that it was nearly impossible for any prospective partners to mount her without assistance - thankfully, considering it wasn’t the Prince’s first rodeo, he was well prepared for such occasions. Having teleported a small stool to himself, he stepped onto the sturdy piece of furniture, grabbed her hips, and nudged the head of his cock to her entrance.

Cadance took advantage of her momentary distraction, lowering herself to nurse on one breast while deftly coaxing milk from the other with her free hand. Likely realizing what his wife was up to, Shining wasted no time; holding her hips, he plunged into her and swiftly fell into a swift rhythm of screwing her. The two-pronged attack was flawlessly executed, wracking her with bliss and sapping her of what little strength she had left.

To say the couples’ ministrations felt good would have been an understatement. Cadance knew how to please mares in a way that stallions simply couldn’t comprehend, seeing as she was one herself, while Shining’s domineering, masculine side allowed him to bend nearly any female to his will. They were two sides of a coin, yin and yang, and Celestia found herself helpless to stop them.

“Moo for me,” Cadance murmured, biting down on the gravid alicorn’s teat.

“Moooooo!” Celestia thoughtlessly complied, overwhelmed by pleasure. “I’m y…your - Aaaaahn - sluttly little cow!”

“Darn right you - Mmmph - are,” Shining grunted, each thrust sending ripples across her massive ass.

Try as she might, it was impossible for Celestia to do much of anything aside from uncontrollably whimper and mewl as she steadily approached her climax. She could last for quite some time by herself or with a single partner, but weathering the passionate storm of both Cadance and Shining was an insurmountable task. Sensing the milking machine being placed back on her breasts, the steady suctioning almost as good as her friend’s mouth, she forced her eyes open and noticed the Princess climbing onto her vanity.

She instinctively lifted her head as Cadance awkwardly crawled over the furniture’s surface and lifted her legs. It would have been unfair that she had all the fun herself, so being presented with the Princess’ pink, juicy muff didn’t surprise her in the slightest. Slipping her arms under the young mare’s legs, she pulled the mare to herself, licked her lips, and dove into her friend’s glistening marehood.

Locking her into position while she was plowed from behind, the Princess of Love groaned and clamped her thighs around her head. Being rutted by a virile stud while eating his wife’s puss, while astounding, was no easy task. She clenched her marehood with each of Shining’s backstrokes and lapped at Cadance’s clit, all while doing everything she could to stave off the inevitable. It wasn’t a matter of if she was going to cum but when, though she’d hold out for as long as she could.

The trio’s debauchery could only be described as legendary. Each attempted to please the other, be it from sinful promises and soft caresses to ruthless plunges and skillful tongue-work, and it spoke to the intimacy that they shared. A threesome among amorous ponies could be hedonistic and very rewarding, yet it would lack the familiarity and care of three ponies who genuinely cared for one another.

Seconds stretched into minutes and longer still, while their passion soared into the heavens, but it came to an end far quicker than any of them would have hoped. Holding Celestia’s mane while fiercely tugging her left nipple, the breath hitching in her throat, Cadance climaxed before either her host or her husband. If she’d been an ordinary mare, this wouldn’t have meant much whatsoever, save for a baptism of her nectar, yet that was far from the case.

A shockwave of unrefined love energy blasted through the room, devastating Celestia and Shining in its wake. The stallion growled and victoriously roared, sheathing the entirety of his length and bathing the elder Princess’ confines with his potent essence. As his hips fitfully twitched and thrusted, ensuring every drop of his seed was pumped as deeply as possible, he leaned in and hugged his lover’s back.

Celestia had been close to cumming as it was, so the combination of Shining filling her and the carnal energy which assailed her did her in in a heartbeat. Her mouth hung open in a breathless scream, her eyes shot wide, and a heady cocktail of her orgasmic juices and his cum erupted from her stuffed sex, making a spectacular mess on the floor beneath her. Listing to the side, trying and failing to keep herself upright, she was rescued by the couple.

Moving faster than should have been possible, Shining and Cadance held her with their hands and magic and prevented her from taking a tumble. She exhaustedly looked at them, smiling to each in turn, and attempted to look appreciative. She could barely hold herself up, she must have looked foolish in her dairy-cow getup, and she was covered in sweat and all sorts of sexual fluids, but that couldn’t be helped.

“C…can - Cough - can I get next?” Cadance croaked, using her sorcery to right her host.

Celestia wearily smirked and glanced over to the bed. “Only if I get to suck him clean first…”

While she was certain that they’d spend the night together and eventually collapse in an obscene pile on her mattress, she wasn’t sure exactly what they’d end up doing. There was a good chance they’d take turns or even break into her extensive supply of sex-toys at some point or another, but that was hardly a bad thing. Regardless of precisely how they were making love, they never failed to end a passionate bout without everyone being completely satisfied - a hallmark of their affection for one another - still, she wondered how or if their dynamic would change once she’d had her foals…

Epilogue

“D…don’t stop!” Celestia wailed, driven forward and back atop her bed.

Cadance thrust up and into Shining’s hand, practically screwing herself on his fingers, while she played with tits. “Mmmmmmm - Fuck!”

Shining grinned from ear to ear, plowing one mare while finger-fucking the other. “Don’t worry, I’m not stopping until you both get a heaping helping of foal-batter…”

Celesita peered down her chest at him, only barely able to see his face above her prodigious stomach and gargantuan bosoms, before she looked over at the mare beside her. Though Cadance had given birth some time ago, the girl had gotten knocked up as soon as she’d given birth to Flurry Heart. With the use of a bit of rather crafty magic, paired with her insatiable diet, she’d grown to nearly as big as her mentor.

Her due date had come and gone nearly a month prior, yet she’d continued to gradually get bigger and bigger. Maybe her advanced age had something to do with her pregnancy, or perhaps her subconscious love of being heavy with foals had delayed her delivery - regardless of the root cause, she’d gotten so large that she’d spent the last two weeks in a custom-built cabin on the fringes of the Everfree forest. Her temporary residence was a bit inconvenient, not to mention away from her adoring public, but she wasn’t there alone.

Shining and Cadance had accompanied her, swearing they’d stay by her side until she’d delivered her child into the world, and she was immeasurably grateful for their presence. Not only were the couple a course of comfort and contentment, but they were the best ponies on the planet to scratch her amorous itch. She planted her feet and lifted her waist ever so slightly, ensuring Shining’s medial ring demolished her g-spot while he pounded against her occupied womb, while she reflexively looked up at the mirror above the bed.

Each of her breasts was broader than her shoulders, her belly was so big that she could hardly walk without it scraping the ground, and her rump was as colossal as it was soft. She’d transcended from a curvaceous demigod alicorn to a paragon of maternity, eclipsing the title Cadance once held, and she’d be lying if she said she didn’t love every second of it. Gone was the bashful, self-conscious mare who avoided making scenes, replaced by the proud, self-assured Princess that motherhood had turned her into.

“Not gonna - Huff - last much longer,” Shining grunted, jackhammering into her and shaking her from her reverie.

“Wait!” Celestia bleated, bringing his motions to an abrupt halt. “Step back for a moment.”

Despite looking very confused by her request, he did as he was asked. As he shuffled back, unsheathing his slickened length from her depths, she shunted power into her horn and teleported herself directly on top of Cadance. With her abdomen and tits squished against her friend’s bust and belly, she smiled down at the mare.

“Tell me if I’m too heavy,” she whispered, adjusting herself and rearing into a kneeling position.

Cadance quickly figured out what was going on, shifting in place to ensure her sex was sandwiched against her host’s snatch. “You’re fine, but…” she trailed off, leaning over to peer at her husband, “we could use a bit of stallion meat.”

The sight of two exquisitely gravid mares pressed together, each expectantly watching him and praying for his affection, proved too much for him to bear. Stepping forward, holding the base of his shaft, he guided his stallionhood between their marehoods. Though he wasn’t penetrating either of them, his cock glided against their clits and caused them both to moan. There weren’t many ways for a guy to get off two girls at the same time, but be darned if this wasn’t one of the best ways to do it.

“You mares ready?” he inquired, lovingly rubbing and squeezing Celestia’s backside and Cadance’s thigh.

“Mmmmhmmm,” the Princesses groaned in unison.

Like a lightning strike, Celestia was stricken by a wave of pleasure when he started slowly thrusting. She adored being filled with a big, thick cock, yet the clitoral stimulation would be more than enough to get her off - that and she had other ways to heighten her bliss. Listing to one side, she lifted one of Cadance’s titanic tits toward her face, leaned forward, and hungrily began to suckle around her friend’s nipple.

Fighting through her bliss, Cadance recovered from the surprise attack and countered. Mirroring the older Princess’ movement, she leaned to the side, lifted her head, and latched to one of Celestia’s enormous udders. As she mutely whimpered around the bud of flesh, gulping down mouthful after mouthful of rich, nutritious milk, her eyelids fluttered.

The pair feasted on one another while the stud - their stud pistoned his length between their needy pussies. The stimulation to their marehoods while simultaneously having their teats nursed upon was simply incredible, creating a rivalry of sorts. While it didn’t matter which one of them peaked first, there was a certain pride to be taken from outlasting each other.

Like an absolute machine, Shining did everything he could to get the pair of alicorns off. Aside from simply thrusting, he used his magic to up the ante. Sorcerously twisting their unmolested breasts, caressing them all over, and even ticking their g-spots with his aura - nothing was beyond them. Though they may have entered some sort of unspoken competition, he was determined to make them both climax before he did.

Moving faster and faster, whipping themselves into a frenzy, the trio lost themselves to the exchange. Celestia and Cadance bucked their hips, grinding themselves against his pistoning shaft, while each suckled on the other’s tit. It was a scene of pure degeneracy, though they genuinely did care for each other. As they reached a fevered pitch, each having been reduced to a bestial shadow of their normal selves, they began to fall like dominoes.

Celestia climaxed first, baptizing Cadance’s groin, thighs, the bed, and Shining’s entire lower half in her nectar. Milk geysered from her tits, all but drowning the mare beneath her and showering over the mattress. Her marehood convulsed and seized upon itself, as she collapsed atop the young Princess.

A split second after Celestia came, Cadance followed suit. Howling to the heavens, she unwittingly unleashed a cascade of her sensual energy throughout the chamber. Much like her host, she gushed sweltering, orgasmic juices onto her husband and the sheets beneath her. With her toes curling, trembling from head to foot, she was joined moments later by her betrothed.

Try as he might, Shining couldn’t stop himself from slipping past the brink. The physical pleasure had been hard enough to endure, but the carnal energies that swept over and through him did him in in an instant. Driving his hips forward as far as he could, he blew his load and painted the two mares’ bellies with his hot, sticky jizz. His legs quaked uncontrollably, leaving him to crumple forward and hug Celestia’s immense ass.

The three lay all but motionless, heaving air into their chests and slipping into a blissful euphoria. It was a wonder that the bedframe could support them all, not for the least of which reasons being Celestia and Cadance’s tremendous girth, but it managed to hold. Grinning like a trio of idiots, their mirth blossomed from a small giggle into a heartfelt laugh.

“Hey,” Celestia quietly began, peering over to the window, “you two wanna try something different?”

Cadance and Shining looked to one another before focusing on their rotund host. “Like what?”

“Maybe we fool around under the stars tonight,” Celestia continued, rocking back into a kneeling position.

Wriggling backward and up the mattress, Cadance nodded. “I’m game ~ how about you, Shining?”

“Sure,” he replied, giving a small shrug, “after we get cleaned up. I’d rather not let my coat get all crusty again…”

Celestia couldn’t have been happier with the way things had played out. She’d soon have the foals she so desperately desired, her bond with the royal couple was stronger than it had ever been, and she’d gotten something that she never knew she needed - a family. Though she loved Luna with all her heart, Shining and Cadance were as much a part of her life as the filly or colt growing within her - making them all but inseparable. Twisting to the side, throwing one arm around the pair, she fought back a joyful tear.

“I love you two,” she murmured, her voice fainter than a whisper.

The couple didn’t say a word, embracing her and returning her love. They’d be together for the rest of their days, even if they may occasionally spend time apart, and she was all the happier for it. For the rest of her days, she could never repay them for the gift and good times they’d given her, and she knew even better times would lay ahead of them…
