Heavenly Spheres

It was a momentous day for the history of the world, Twilight Sparkle knew. She was an expert on such events, given that she'd been directly responsible for many of them, this one included. Twilight stood before the greatest engineering marvel she'd ever worked on over the course of her long life as princess, though of course she'd had help from hundreds of workers, colleagues, and friends. In fact, she'd just finished a dramatic speech thanking them all and opening the door to the future.

Behind her, resting upon its enormous titanium landing struts at the edge of the sprawling, bright mega-metropolis, was the arc which would shelter those brave ponies who chose to follow her into the stars. The spaceship was enormous, the largest of any vessel ever built, at ten times the size of a cruise ship, big enough for twenty thousand with room to spare. She was named the Sundancer, after two old friends who had been as passionate about the sciences as Twilight was. Its sleek, silver teardrop shape, gleaming in the light, was only marred by relatively miniscule exterior features, aside from the four mighty rocket thrusters.

Ponies ascended narrow loading ramps or flew upwards to the airlocks, with varying degrees of excitement. Some had dreamed of this day their entire lives, while others merely had nothing left to tether them to Equus, hoping for a more fulfilling tomorrow elsewhere. She would have brought other races, too, but the requirement of a substantial, sustainable population demanded otherwise. It would be at least four centuries before the Sundancer reached her planned destination, even with the lightspeed Dragonfire Drive Twilight had invented. There were precious few habitable planets in the galaxy; Twilight had been lucky to locate the one, given its proximity.

Moreover, the ship's blueprints were public; other creatures were already hard at work assembling their own colony vessels. However, this one was Twilight's to steer, as indicated by the sharp white captain's uniform she now wore, complete with a cap in place of her crown, thought her billowing mane stayed unimpeded. Looking over her shoulder, the sight of so many setting out to forge into the unknown under her care nearly brought tears to her eyes.

A polite cough brought Twilight's attention back to the present. Four deeply familiar faces approached Twilight through the elevated plaza's receding crowd: Celestia, Luna, Cadance, and Spike. At twice the height of the average pony, eleven feet, not including her horn, Twilight tended to loom over most, including her fellow alicorns. Her smile widened as they closed the distance. Now that she was among family, Twilight's supply of eloquent words ironically ran dry. No one else spoke either, worry and pride warring on their features. It wasn't the first time they'd skipped the pleasantries. But that thought extended and lingered in Twilight, and her smile sunk somewhat. "You came to see me off," she eventually managed.

"As if we wouldn't," declared Celestia, her posture unusually tense. It was subtle, but Twilight could tell.

Spike hummed in agreement, though it came out as more of a volcanic rumble. The fully grown dragon towered over even Twilight, his toothy smile bittersweet.

There was a long pause where the group did nothing but stare at Twilight before Luna ended it, ruffling her wings behind her dress. "Save travels, Twilight," she uttered, with solemnity. "I am glad I will finally be able to pay Tia back for all those years she had to take up the arduous task of ruling without me, difficult though it may be."

Celestia grinned knowingly, the former steward of the sun having elected to remain in retirement.

"Well, this old Royal Advisor will be here if you need any help," Spike confirmed mischievously before turning from Luna to his first and best friend. "Be sure to write, you hear?"

"I will, I promise. So will Flurry Heart," Twilight reassured. Her niece was already on the ship, helping direct everypony.

"I know she will, no matter how... preoccupied she gets," confirmed Cadance with a nod. However, her eyes drifted away from Twilight's. "Still, my baby girl, and my precious sister, leaving..."

Twilight's heart went out to Cadance. But it was Celestia who spoke next. "Oh, enough of this dire goodbye talk," she said, waving a hand as if to banish the melancholy. "This is no ending, it's a new beginning! It should be a time of pride, for all of us."

"Y-Yes," Twilight choked out. Overwhelmed, she simply invited some of her greatest joys closer by opening her arms wide.

Though they had to maneuver awkwardly around the bowl-shaped levitation fields she was maintaining with her magic, along with the two other spells she was actively casting upon herself at the moment, her fellow alicorns nevertheless wrapped Twilight in a firm group hug. Twilight silently wracked with emotion, Spike coiling his tail around the four of them as she shared in their presence, and they hers, for what may have been the last time. In all likelihood, Twilight would never return to her birthplace, at least not for ages. All present knew that, were they to start, the sentiments and well-wishes would never stop. So, one at a time, they backed away from Twilight, faces flush with conflicting feelings.

Once the moment had gone on long enough to cement firmly in their memories, Twilight turned away, barely maintaining her composure with a series of deep breaths as she retreated into the Sundancer with the last of her passengers, as ready as she would ever be to launch friendship and harmony past the stratosphere.

The morning for Twilight was a typical one. She didn't want to jinx it, but everything had gone smoothly so far, with no major hiccups. After the initial launch, it was possible to adopt a new routine, but life on the ship was still extremely busy for her. Not too much more stressful, as she had long since moved past her freakout days, but keeping everything running smoothly required she be more thorough than running the country, if only because even a single critical system failure could mean the deaths of everypony on board by vacuum or spell rupture. Of course, her greatest responsibility always came first, chronologically. Some needs could not be avoided, after all, whether you were an alicorn or not.

Having finished her usual breakfast and hygiene regiment, Twilight flew through the heart of the Sundancer, her wings straining a bit under the effort despite her fitness and their size. The central portion of the ship was a vast, open space, divided into two halves. In the front were public spaces, a lofty maze of colorful shops, eateries, and entertainment, ranging from parks like when Twilight was a foal to virtual reality arcades. Behind the great mall were the vertical farms Twilight was soaring through, the suspended, layered cubes of produce carefully tended to by members of all three tribes. Above it all, panels emitted artificial sunlight along with the illusion of a clear, blue sky.

Reaching the far side of the farms, Twilight landed before passing through an automatic door. Ostensibly to admit rowdy pegasi mid-flight, the larger doors were used throughout the Sundancer's halls partially so she didn't need to duck constantly. She navigated the grid of the operations quadrant with the ease of one who had memorized the layout. Other ponies waved up at her in greeting as she moved, from mechanics in grease stained uniforms to composite armored guards. Twilight greeted them all cordially, in a manner that had long since become automatic, though inside, she was more than a little uncomfortable. Mainly from the typical, bodily ache, but some portion could be pinned on the looks she received from a few mares and stallions, looks which lingered on her for too long. It wasn't their fault, not really, so she tried to put it out of mind.

Soon, Twilight reached her destination: the Sundancer's secondary reservoir. Unlike a typical water storage facility, this reservoir room was a wide, tall cylinder in and of itself, with an entrance on both sides of the curving wall. Below Twilight, the floor was a durable alloy mesh, reinforced with crossbeams, and down through it was the reservoir proper, a deep tank. Currently at about one third capacity, white liquid filled the bottom. Sitting on a swivel chair by the controls for the pumps was a pastel pink earth mare with a curly orange mane. She was Pi Pie, one of Twilight's most capable engineers and a descendant of her dear friend Pinkie.

"Ah, morning, Cap!" Pi greeted with friendly exuberance, spinning around in her seat. "Everything's all set for you, no issues here or down the line."

"Great," Twilight commended. Her horn sparked with wavering motes of light as the cups of magenta magic floating in front of her flexed slightly. "I'll start right away, then."

Walking over to the center of the room, her back to Pi Pie, Twilight unbuttoned her jacket, shrugging it off with a flick of her wings. Her blue undershirt followed it, fluttering away to reveal... absolutely nothing. Her chest was bare, both of a bra and what was typically found underneath, just featuring smooth purple skin. However, the truth would not be unseen for much longer.

Doublechecking the area was clear, Twilight released her spells, the near-constant glow of her horn fading. Her view was immediately filled with a wall of purple, and a huge, meaty thug echoed through the room.

She still hadn't totally gotten used to her enormous, enhanced breasts. All six of them. Each was wider than most ponies were tall, at eight feet in diameter. They were so, so big that Twilight couldn't keep them all in front of her when she walked, instead opting to pull the middle pair out to the sides as the other four remained stacked, literally and metaphorically. Her great strength alone wasn't enough to balance with them, so she generally held all six from beneath in bowls of levitation, lifting them into position. Normally, Twilight used partial invisibility to hide her boobs alongside partial intangibility to fit into her clothes - and everywhere else. But she couldn't get rid of their sheer mass, nor stifle her ability to feel them. And every day, Twilight awoke almost painfully full, even without her conscious efforts. It didn't help that her boobs themselves had become her bed, since dozing on her back or side would wind up with her being suffocated beneath her own ungodly rack.

Her dark violet nipples were the size of kitchen garbage cans, excluding the areolae, and boiled Twilight's blood in their hardness. Hundreds of pounds of titflesh molded against itself, sweaty and bloated with cargo, all a part of Twilight now, all she could see and touch. Without any more preamble, she reached out with her horn again - her hands both too few and unable to reach - to grab her nipples. The glandular valves had been primed and ready from the moment she'd awoken, waiting for the appropriate trigger. And Twilight did just that, with all six at once. She wrapped her aura around her mega-sized nips as strongly as she dared and pulled.

The effect was immediate, like a bolt of lightning striking her. With a sharp gasp, milk erupted from Twilight's breasts as if they were fire hydrants, raining down through the floor to flow into the tank with cacophonous, thick splashes that echoed off the walls. The milk from her upper pair actually reached the ceiling as it arched high into the air from the pressure, splattering all over the place. Eyes clenched shut, Twilight's waist rolled against her boobs as she fidgeted under the sensation, unable to stop a slight wetness from building between her thighs, barely worth noting compared to the gallons upon gallons rushing from her breasts with every heartbeat. The level of the reservoir rapidly rose, the amount of hot liquid Twilight was gushing rivalling the fiercest wild thunderstorms, more than every other mare on the ship could make in their collective lifetimes.

If Pi Pie was aroused at all by the display, or thought the whole arrangement awkward, she never showed it, which Twilight appreciated (and was why she stationed her here in the first place). Having another pony watch her sighing and squirting under triple the usual pleasure like this was embarrassing enough already.

As milk flowed ceaselessly from her ludicrously fruitful nipples, Twilight's body occasionally shaking from the sensation of production as she buried her nose and hands into her own cleavage, her thoughts turned to how exactly she'd reached this point. The state of her impossibly massive bust, strangely enough, was what made this entire space colony endeavor possible in the first place. See, beyond maintaining gravity or speed, the main problem of taking a prolonged trip through the void was energy. The ship's engines, along with life support and everything else, demanded a large quantity of power to run, and methods such as photovoltaic cells didn't work in the higher plane through which the vessel moved. A mana reactor provided more than enough, but consumed large amounts of nonspecific matter for fuel, far more than they could bring onboard.

Twilight had combed through countless books and databases for the solution, growing increasingly frustrated with each passing month. At her wit's end, she'd stumbled upon a list of popular bedroom spells. One of them, originally invented by a wet nurse, was a permanent enchantment that tapped into a pony's innate life force to increase breast size, as well as enabling the mare to lactate at will, essentially. The effects varied from pony to pony, the resulting size (usually one or two cups) and the drain on life expectancy with prolonged use being rather variable. But, as Twilight was immortal, she could make as much breastmilk as she wanted with no negative effects. The four extra boobs she'd gotten were unexpected - her current theory being something to do with there being six Elements - but other than that the spell was exactly what she'd needed. Using nothing but her own body, she could keep the reactor running at full burn indefinitely. Recycling other resources within a closed system like the Sundancer simplified to a matter of logistics and appropriate technology, with that much power available.

After about half an hour of ceaseless output, the tank had reached near capacity, just as the throbbing pressure within Twilight's chest faded to a dull ache. Centering herself, she recast the spells on her breasts, which vanished from sight. Once she'd dressed and literally picked herself back up, Twilight turned to leave.

Pi Pie shot Twilight a thumbs-up. "Everything's all set. See ya tomorrow, Cap! Enjoy the rest of your day!"

Twilight's smile was genuine, but thin. "I always try to, Ms. Pie." When you lived for the sake of those in your care, taking time for yourself was secondary.

Speaking of, her next stop was the Sundancer's bridge. It was close by, near the engine rooms, so Twilight didn't have far to walk. Putting the bridge far away from all the critical components simply for the sake of a view was stupid engineering when you had sophisticated video cameras. She made sure her posture was dignified as she moved along the metallic pathways, lines of soft light embedded into the floor and ceiling. Although, Twilight's tail still swished on occasion as the last motes of bliss filtered out of her system. Still, she was in full control by the time she arrived, the entry to the bridge marked by the Sundancer's 'cutie mark', a violet sun orbited by white sparkles.

Inside, a substantial team of ponies scanned computer screens and holograms, watching the data tables and transparent scematics attentively. Most remained focused despite the sound of her hoofsteps, with the exception of her second in command, who stood to salute. He was a beige unicorn in a lavender version of Twilight's own uniform.

"Farseer, status report," Twilight intoned.

"All systems are within parameters, Captain," he said, now at ease. "The princess broke one of the walls in her room again, but we sent a couple of repairponies up to weld it shut."

Twilight sighed. Of course Flurry would go overboard again. At least she was keeping most of the rowdy bachelors on the ship happy and localized. "This can't keep happening. I'll go talk to her shortly, see if I can convince her to tone things down somewhat."

"Permission to speak freely?" When she nodded, he continued. "Good luck with that, Twilight."

"I'm aware," Twilight confirmed, sporting a nostalgic smile. "I've known her for centuries. Still." Shaking her head, she broke away from him, roving further into the bridge.

One after another, Twilight began to greet and observe the rest of her officers. Each managed a specific area, from navigation to climate control, and she liked to get more detailed summaries of the ship's goings-on firsthoof, ask for specifics. And yet, this process wasn't as easy as she would have liked. Many of the scientists and engineers had trouble forming words in her presence. They tried to hide it, for the sake of professionalism, but the notes of awe and longing in their eyes as they looked up at and near her were unmistakable for a pony as experienced at reading others as Twilight. She could hide her own discomfort far more effectively, but it was still there as she traded numbers and guidance with them.

Twilight's mood grew pensive as she flew back through the farms to Flurry's room. She'd been meaning to do something about this predicament for a while, but couldn't come up with an adequate solution. It was wrong to curtail ponies' behavior, especially when their actions weren't truly harmful. Twilight had come to terms with her own magnificent attractiveness ages ago, but ever since enhancing her breasts, it was as if some ponies simply couldn't stop thinking about her in that way.

Flurry Heart, meanwhile, had embraced that aspect of herself completely. So completely, in fact, that she was known as the Princess of Sex. And by extension, fertility. The whole reason she'd joined her on this historic mission was to, quote 'help accelerate population growth, wink wink'. Though Twilight didn't see eye to eye with her on everything, Flurry's heart (heh, wordplay) was in the right place, and she did love her as family. Even when she got too wild during sex and broke something.

Her rooms were on the border between the residential and entertainment zones, nestled into the hull where the floor met the 'sky', behind a store that sold fantastical, often erotic simulations. A sign reading Flurry Heart's Royal Delights marked her abode in flowing cursive. Moans could be heard from within, and Twilight's ears bent in annoyance. Of course. She walked inside without ceremony.

The repairponies had indeed arrived, but they weren't fixing the bucked-in section of the wall next to Flurry's bed. Instead, the two colts were on said bed, their tools and garments cast aside. Her niece, equally naked, was gyrating her substantial hips on top of one of their muzzles as she held the other stallion up to her chest, looking like a child next to her as he buried his cock into her basketball sized tits, the flesh bouncing around him as he thrusted, groaning. Flurry pulled away from a deep kiss, saliva briefly connecting their mouths, before turning her head to Twilight. "Oh, hey Twilight!" she greeted, her tone perfectly ordinary.

Twilight shut her eyes, bringing a hand up to rub her temples. "You were supposed to let those two seal the wall, not drag them into bed."

"I know, but they can do that after," Flurry insisted, her huge wings flexing as she squeezed her sopping thighs around her catch. "I'm trying to get pregnant again, and they wanted to help me with that first!"

Both colts' lips were otherwise occupied, the one she was holding biting softly at her neck as he sniffed her sweaty, billowing mane, so they were unable to confirm this. But well, it was rather obvious.

Twilight pursed her own lips in disapproval, staring at Flurry and trying to ignore what she was doing. It was more than a little rude that she wasn't stopping to give Twilight her full attention, but then again, Twilight had been the one to interrupt proceedings. "Ugh, fine. Just don't keep them for too long. And please try to be more careful in the future. Enjoying yourself is fine, smashing so vigorously it possibly wrecks part of the ship's power grid is not."

"I know, my bad," she said, apologetic. "Won't happen again, I promise. No more of that position." The fact she wasn't moaning anymore was a testament to her experience, able to turn off such exhalations on command. Though, as evidenced by the entire situation, she still had more to learn about impulse control. Still, as a princess, she strove to keep her word, and that was enough for Twilight.

Initially, she was going to just leave them to it, go get ready to teach her class on high-level magic at the on-ship university, but Twilight paused, an idea striking her as to how she could approach the escalating issue of her enticing presence. And it was a rather good one: consult the expert. "Actually, Flurry? I'd like to ask you something."

"Yeah? What's wrong?" Flurry wondered, reaching down to expertly stroke the dick of the mechanic she was straddling.

Twilight averted her eyes. "Well, a lot of ponies are losing focus whenever I'm around. My physical assets are evidently a significant distraction, even only in their imaginations."

Flurry laughed, juices trailing from her nethers as she shifted around. "Of course they're ogling, your body is even more glorious than mine! Are you letting anypony bang you?"

Twilight sighed, crossing her arms. "No. I'm too busy, and I don't want to play favorites anymore. That just leaves so many envious."

"Then make the time, Twi! You have needs, same as all of us," Flurry noted. She'd gotten down on all fours, letting one stallion mount her ass from behind while the other plunged up into her pussy from beneath her, perky boobs bouncing above his head. They'd had the courtesy to keep quiet during their conversation, which was nice. Or maybe Flurry Heart was taking up their senses like a horny magnet. Probably the latter.

"Make time when?" Twilight waved a hand Flurry's way. "Your orifices are open 24/7, I don't have that luxury, as I have so many other responsibilities. And without that universal availability, it wouldn't be fair. But if I don't let ponies approach me for sex at all, this problem isn't going to go away!"

Shrugging with her wings, Flurry's body rippled and tensed, coaxing the stallions to release inside her. "You're the Captain, so you can make the rules, right? Lay down the law, make a sign-up sheet or something. You organize everything else on the Sundancer to the letter, why not your own unwinding sessions?"

Twilight gasped at the same time as the two repair colts, though hers wasn't the result of an orgasm. The missing piece clicked into place as if it was meant to be, her mind whirling with sudden inspiration for a new cornerstone of her schedule. "Flurry, that's it! I think I know just what to do! Thank you!"

"It was my pleasure," Flurry confirmed, sitting up between the afterglow-addled stallions, idly reaching down to scoop some stray cum from her labia into her mouth with a finger. She smiled contentedly.

Her own smile broadening, Twilight clapped her hands together excitedly. "I'll leave your three to your work, then. I have some new ordinances to enact!"

A few days later, the resulting announcement went up via the same digital news bulletin as Twilight's other minimum-urgency public updates, a collection of articles only the adults onboard typically read. It was a new holiday she had outlined, one which coincided with the long defunct autumn harvest festivals from her youth. As it represented a chance for the Sundancer's denizens to give back to Twilight for all her hard work during the year, and the time when she would give everypony access to her body, Twilight called it Thanksgiving.

Only one major event happened every Thanksgiving, in the evening, more than a simple feast. Twilight would allow those interested the opportunity to do essentially anything they wanted with her, sex-wise, and she would be strictly off limits at any other time. Moreover, it was to operate as a passage into adulthood, of sorts. The only ponies eligible to participate would be those who turned eighteen in the previous year. Effectively, this meant all stallions and mares got a maximum of exactly one lay with Twilight, period, and no amount of subsequent flirting would change that. Nor would there be a need to eye her up if they'd already seen everything.

Of course, this meant that all ponies currently older than eighteen would miss out. So, this first, inaugural Thanksgiving was open to all wanting adults on the Sundancer, and would last as long as it took for Twilight to take care of each and every one. Needless to say, she was worried, but it had to be done. She'd made all the necessary preparations. The reservoir room, the designated venue for the Thanksgiving gangbang, now bore multiple enchantments of Twilight's own casting. Nopony could get pregnant, and all but herself would be compelled by a geas to leave immediately after they'd climaxed. The worst that could happen is that she'd lose her sanity drowning in a sea of pleasure, and would that really be so bad?

Needless to say, news of Thanksgiving rapidly spread to every corner of the Sundancer, carried in excited tones from the quiet office spaces to the roar of the engine rooms. More than a few expressed their anticipation to Twilight herself as they crossed paths. This, along with the many, many questions she was fielded, proved almost as bad as the lustful staring. Really, she'd posted an embarrassingly comprehensive list of what sex acts she would tolerate and everything, they shouldn't even have questions!

Eventually, the promised hour arrived, and Twilight's prospects were daunting, in a manner she found both flattering and mortifying. According to the guards on staff (IE: those not participating), over a thousand ponies had registered to participate, enough that even the comparatively short fraction in line at the moment snaked through the halls outside the secondary reservoir. Some quick mental math on Twilight's part had rendered the tips of her ears red; It would be almost impossible to get through them all in under 24 hours of nonstop fucking.

For Twilight, the seconds ticked down as she waited inside, alone, separated from the aroused throng by nothing but a thin egress. Above, the lights had not been dimmed. They would see, they would touch, they would taste. Her divine force of will, one which held her back, kept her above what her niece embraced, had, for this day, been cast aside intentionally, along with all her clothes. Decades upon decades of unfulfillment rushed to the fore, and Twilight's swollen pussy ached in anticipation of what was to come. She watched the door with shallow breaths, thought of nothing but sex as she rested atop her six tremendous mounds of femininity, tail flagging, her nipples level with the floor and radiating in all directions, already firm and dripping.

As her guards punched in the code to unlock the front door, cheers rang out, the dull murmur replaced by a cacophony of hooves on metal as Twilight's mates for the day filed in. A light blue Pegasus stallion in his prime was the first to enter, he and another ten-plus ponies rapidly approaching Twilight. His was a face she recognized. Beginning to strip, he said nothing, his eyes wide and roving.

Twilight's lips upturned impishly, her chin cradled in her hands as her elbows pressed onto her breasts. "If it isn't young Skylark. Naughty boy, first in line to bang your great aunt. Flurry must be proud."

Unable to find words and driven entirely by simmering desire, Skylark, now nude, his athletic body and raging hard-on in full display, flapped up and over Twilight. He landed on her rearmost knockers, which jiggled strongly as they absorbed the force, eliciting a moan from Twilight. With a deep growl, he grabbed her double-wide hips in both hands, shimmying across her tit-bed before jamming his thick dick into her pussy. Her needy depths accepted all of him in one go, and she barked out a cry. "Ah, yes!"

The other stallions didn't mind her main hole being taken when there was so much more of Twilight to play with. One threw his whole body against a tit, making upside-down snow angels as he bucked his hips, that spot bearing a greater heat and pressure. Twilight felt every motion through her massive yet sensitive mammary. Two more colts pried open her cleavage, smothering themselves completely as they squeezed into her velvety canyons, which sealed behind them due to Twilight's sheer weight. A mare had straddled one of her middle breasts, rubbing her lower lips back and forth across the top of Twilight's nipple, so big and engorged it could support her weight. It all felt simply amazing.

Her heart racing, Twilight egged them on. "That's it, grope and fondle your captain! Feel up my big, big boobs with your whole bodies! Give me as much ecstasy as you can!" Dirty talk was really just friendly banter about sex, and all ponies knew how much she excelled at friendship.

Naturally, they responded with gusto, thrusting and writhing atop, beneath, inside Twilight. She was overwhelmed by the myriad sensations, her limbs mirroring their frenzied, involuntary motions. Skylark's pace redoubled, the sensitive walls of her pussy rubbed and stretched by his throbbing flesh, his ballsack smacking into her clit with each repetition. He doubled over, pressing his muzzle into the small of her back as he moaned in building pleasure.

And he wasn't the only one penetrating her. As her nipples, hanging in the open so enticingly, were so huge, stallions were actually able to fit their cocks inside her nipple ducts, the steady trickle of milk from Twilight's arousal providing enough lubrication to enable their tightness to be violated for the first time. Soon, four of her nipples were being used, the ponies fucking her sighing in contentment and rapture as they leaned into her rippling flesh, subsumed by her warmth and softness. It was just as incredible for Twilight, whose mouth hung open, overwhelmed, eyes watering as the onslaught of new, wonderful areas being stroked reached a crescendo. "Oh fuck! Oh fuck! More! Don't stop! Drive me wild! Make me— mmglph."

Her lustful pleas were cut off by the sudden intrusion of a dick in her mouth, a heavyset, dark grey earth pony having taken advantage of the opportunity. Not that she particularly minded, at the moment. With a firm grip on a small fraction of kneadable top boob in one hand and her waving mane in the other, he grunted as he jammed his extra meaty cock across her flicking tongue and far into her esophagus.

The ripe, musky aroma of stallionhood inundated her nose as he deepthroated himself into her, turning Twilight's powerful frame into a heavenly spitroast. Being used, being commoditized, on top of simply knowing how many ponies wanted to be with her... it was a superb feeling for Twilight, an itch finally being scratched, suffusing her with primal ecstasy. At some point, Skylark had popped off, his hot cum the first of many loads to hit her insides as his length pulsed within her. She moaned around the dick in her throat as her eyes rolled back, the stimulation to her upteenth erogenous zone, combined with the creampie from her virile relative, sending her body rising past the point of no return. Intense heat built in her core as well as her six immense breasts before Twilight could contain herself no longer.

With a cock-muffled shout of sheer relief, Twilight came at last, wings outstretched and legs tensed. Though her cunt was busy wringing itself out of so much tension, it was her tits that really let everypony know of her orgasm. Milk built up behind her nipples before lancing out explosively, the force of her lactic ejaculation sending the unfortunate (or very fortunate) individuals currently boning her nipples sailing away to crash their asses onto the floor before being instantly soaked from head to hoof in her thick, hot milk, adding to her output from that morning. It streamed over their bodies and into their opening mouths as Twilight brought her arms in close to herself, back arcing as the flood of hormones swam through her system. It was glorious, like the rush of a confirmed hypothesis to the fifth power.

Her myriad lovers, those not already wandering out the rear reservoir door in a state of nirvana, seeing their usually composed captain break down and cum far more than buckets was too much. A symphony of grunts and groans reached Twilight as mare and stallion alike climaxed with her, riding their highs from her cleavage or their spot amidst the creamy deluge.

Yet, there were always more ponies waiting for their turn, let in by the guards as spots opened up. For as many who wanted the same things, a chance to fuck and fuck whatever thirsty hole or ton of boob of Twilight's they could get their hands on, just as many attacked Twilight's body with personal verve. For every guy who pistoned into her pussy, ass, muzzle, or nipple, there was another who got Twilight's motor running in a way she hadn't imagined. Stallions fucked the space between her boobs and her stomach, perpendicular to the norm as they rocked into Twilight from all angles. They brought vibrators to get her shaking, squeezed her boobs fiercely with earth pony bear hugs or magic. Couples showed up just to make use of Twilight's breasts as she did, using her as a plush mattress and giving her a show in the process. On and on and on.

And with each fresh batch of ponies, Twilight became increasingly dazed and increasingly pleased. Each climax was greater than the last, her body gradually embracing its role as an instrument of sex. Mares bent over in front of her nipples, stuffing their wombs to bursting with Twilight's peerless output, redoubled each passing hour. As her tremendous tits continued to be played with, their weight spread out, and Twilight sank deeper and deeper into her own chest, surrounded by herself as her own sweaty cleavage rose feet above her horn, though there were always ponies in the thick of it with her, fucking her.

Totally lost in the act, vision distorted as her pupils went heart-shaped (an odd arcane phenomenon, that) Twilight soon found herself hungrily gripping and stroking off any erect dick to arrive within range of her hands, moaning as she did, and her namesake magic became totally out of her control, her horn shooting off pink and white sparks that transferred tiny fractions of her experience to any they happened to flutter down and touch. No longer bearing mere boobs, Twilight had bulbous nexuses of joy joined to her torso, giving and receiving unmatched quantities of liquid love.

By the time it was all over, the last stallion departing, Twilight had been fucked so silly it was as if she was having an out-of-body experience. Without thought, trapped in an endless afterglow, she observed. Her intermittently gushing tits, having gone through dozens of orgasms, had filled the tank faster than it could be emptied, even at the maximum rate, and thick milk hid the mesh of the floor, sloshing against her breasts. She was absolutely covered in semen, the sticky substance mashed into her skin and hair by roving hands. It clung to her cleavage, dripped down her nipples, and caked between her feathers. Twilight's stomach, cunt, and ass had been inundated with the stuff, to the point that the excess slowly working its way out of her alone could be measured in pints. Most striking of all, her mane and tail were more white than purple, marked by countless cocks.

The next conscious thought to pass through Twilight's head, once recovered from her stupor an indeterminate period of time later, she voiced aloud, throat raw and voice weak. "Why didn't I try this ages ago?"
