Successor Assistance

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.
