"Everything we do here in the past, even the smallest change, can snowball into an avalanche of trouble for the future!" Twilight exclaimed, bringing her cloud snowball to the end of its cloud track.
"Oh, next you'll be telling me that the fate of all of Equestria hangs in the balance!" Starlight retorted, destroying Twilight's cloud diorama with a sudden burst of azure magic. 
"It does!"
"Spare me your overblown ego! Nobody's friends, not even Princess Twilight's, are that important!" Starlight punctuated her sentence by casting another bolt of magic at a group of pegasus colts and fillies. 
Her target in the group was the younger version of Rainbow Dash. The bolt of magic struck its target and the young filly hurtled way off course, leaving the two colts of the group an easy way to victory. That small change, the new winner of a race in place of Rainbow Dash, would set about changes to the future that not even Twilight could predict. The last few times it had happened, Twilight had needed to face off against almost all of her previous foes, and each time she returned, Starlight still didn't understand the damage she was doing. No matter how much Twilight tried to explain the predicament and come to a solution that didn't involve wrecking the timestream, Starlight was too blinded by anger to even pay her the slightest bit of attention. There was only one course of action left to take; if Starlight wouldn't listen to Twilight then she'd have to make her see it instead.
"I don't know how important other ponies' friendships are to the future, but I can show you what the world is like without mine!"
Twilight lunged for Starlight, just as the entrance to the Time Tunnel appeared in the sky to sweep her up to the new future. Catching the pink unicorn in her arms, Twilight held on tight to ensure that no matter how much she struggled and Starlight wouldn't be able to free herself from her grasp. Together, along with Spike, the trio were sucked into the portal and sent careening through Time. Colours flashed before their eyes, fragments of events that they may or may not have known whizzed by. Twilight saw herself fail the entrance exam to Celestia's school, Spike saw a whole lot of nothing and Starlight saw changes to her friendship with Starburst. Despite seeing her friendship with her closest friend change for the worst, Starlight still wasn't convinced. This was nothing more than Twilight messing with her, no doubt using some kind of Alicorn magic to create false visions as they travelled. If she could just get away from her, break this bond Twilight had created between the two, then everything would return to how it should be. She was certain of it. She writhed and squirmed in Twilight's grip, slipping down her captor's body. Twilight was too overwhelmed with the visions of an altered future to notice what Starlight was up to.
The pink unicorn quickly took advantage of Twilight's distracted focus and fired off a bolt of magic, just enough to flash the poor mare's eyes. As she had planned, Twilight reached up and rubbed at her eyes, completely freeing Starlight from her grip. With a triumphant roar, that was subsequently drowned out by a sudden burst of magical energy around them, Starlight was free. She drifted away from Twilight, drawing closer and closer to the edge of the tunnel. Now she saw visions of the future that Twilight had been privvy to. Streets completely empty, towering, immaculate buildings left empty. She swore she heard the cry of a baby foal somewhere around her too. Further and further she drifted until she felt an unusual sensation against her rear.  Then it spread to her legs as she kicked them back and forth to spin herself around. With a further kick of her legs, she spun enough to see what was going on. Her body was drifting outside the confines of the tunnel, it was breaking up, dissolving into the river of Time. Ever move she made seemed to pull her a little further out of the tunnel, dissolving more of her body into the flow. She felt numb below her waist and the sensation was only spreading higher. Worry quickly set in her eyes going wide as the reality of what was happening began to set in. She refused to look at Twilight, to ask her sworn enemy for some assistance in this moment. In amongst the whizzing of magic and the booming sounds of alternate realities as they crashed around her, she could hear Twilight calling out to her. Typical Twilight, always sticking her nose in where it didn't belong. Starlight didn't need any help, she was perfectly fine on her own. She'd get out of th-
Everything went white, all the colour of her surroundings sucked into a void of nothingness. Starlight moved her head to look around, but without a frame of reference to look at, it felt like she wasn't moving at all. Even when she tried to stare at her limbs, she found that they too had disappeared, instead replaced by the vast whiteness around her. She was somewhere and nowhere all at the same time. A dull whine pierced her ears as she floated there in limbo. It grew stronger with each minute that passed by, eventually reaching a point where Starlight was forced to cover her ears to block it out. She couldn't think about anything else, just this loud whining in her ears and the complete lack of anything else around her. Just when it felt like the sound in her ears would be her undoing, it stopped. In its place came the sound of voices she didn't recognise, quieter than the whine but nowhere near coherent. It was like they'd all been put on fast forward, their words all blended together into one big jumble of sound. Around her, buildings began to fade into view. The outlines of grandiose structures painted in purple, blue, gold and even white. It was as though someone was drawing in the buildings with a celestial pen or paintbrush. Bit by bit the scenery started to get a little more familiar. Starlight had seen it before, in her youth, when she and Sunburst had been friends. The regal turrets and castle-like structures were reminiscent of Canterlot. A far cry from the Town of Equality she had built on the outskirts.
When the buildings were a little more focused and she could make out the finer details, the non-structural things were filled in. Plants were the only organic matter that she could see, there were no ponies for miles in any direction. The voices she could hear began to die out, growing slower and more coherent as it did so. Before they disappeared completely, Starlight managed to hear two words. Two words thatg echoed in her mind as she finally got her limbs and body back.  Oh Celestia!  The words didn't seem to be said in frustration, nor did they seem to be spoken normally. There was a harsh pang of desperation to the words, as though someone was asking, no, begging for Celestia to do something. Still, the fact that Princess Celestia was still around in this altered future meant that at least some things were still the same. Twilight didn't know what she was talking about. Everything was fine and once Starlight found Twilight to expose her lies about the altered future, the better. She'd be able to go back and enjoy her life of Equality and Sameness, perhaps even spread it out beyond the borders of her town.
Finally able to move on her own, Starlight took her first tentative steps forwards in the new future. The lack of other ponies was surprising to say the least. From what she recalled of Canterlot in her timeline, you couldn't walk more than a few steps before rubbing shoulders with someone else. All the shops lined Canterlot's pristine streets were closed and a sign hung on their doors, each one carrying a variant of the same text.
Closed for first of the month. If you're reading this, then you know where you should be.
Starlight correctly guessed that it was some sort of holiday, but for what she couldn't be sure. Not one of the signs detailed just what kind of holiday it was, only that if she was reading this, then she was expected to be somewhere else. She continued to wander down the empty streets, looking for an indicator of just what she was supposed to be doing.  A little further down the street she happened across a semi-dry trail of liquid that led the way down two other streets. To her left, the trail was the dryest, but to her right there was still a gleam of moistness to it. She resolved that someone had made the trail and whoever it was would be on the wettest end. So off she went, walking to the right and following the trail to see just what was on the other end.
A couple of minutes of walking yielded some quick results. As the trail grew wetter and the shimmering of light caught in the fluid grew stronger, two ponies appeared in the distance. Standing tall and proud, their coats white and decorated with the familiar guard uniform of Celestia's Royal Guard. The gold and blue combination was certainly familiar, but whether or not their allegiances were still the same was up for debate. Starlight quickened her pace to a jog, closing down the distance between her and the pair. As she drew closer, she noticed the guards seemed to be walking with an odd gait. Their legs were bowed outwards as they staggered forwards, using each other to walk on their patrol. Drawing even closer, Starlight saw just where the trail had come from. Both of the guards had stomachs that were swollen far beyond what one would consider normal. They looked like they'd each been stuffing themselves at an all you can eat buffet and had ignored every natural instinct to stop. Most startling of all though, was the fact that lower area of their armour, appeared to be leaking. The same shimmering, pearlescent fluid that she'd been following so far. She shuddered to think just what it was, but deep in her mind she had an idea.
The guards suddenly whirled around as the sound of Starlight's footsteps drew their attention. "Hey! What are you doing out here? Don't you know what day it is?"
"Errr, the first of the month?" Starlight replied, using what limited knowledge she had to her advantage.
"Exactly! You should be at the castle with everyone else! Nobody is supposed to be wandering the streets at this hour."
"Except guards like us, who've already paid their dues to the Princesses," the other guard reminded.
"Oh, I was on my way! I just, uhm, slept in! Wouldn't want to miss out on giving those ol' dues to my favourite Princesses, y'know?" Starlight's amateur dramatics left a lot to be desired, but if it meant she wasn't breaking some kind of new law, then she'd do her best.
"See to it that you do," the first guard replied, running his tongue across his lips. "The Princesses always enjoy a latecomer."
Starlight hurried past the guards and put some distance between them before they decided to escort her personally. Or do whatever it was that guard was thinking about. She spared a single glance over her shoulder at the guards before hurrying off in the direction of the castle. She'd been to see it once or twice in her youth, but she'd never actually been inside it. Guess changing the future had more benefits than she initially planned for. Still no negatives as far as she could see, aside from the oddly swollen and leaking guards, but that was hardly something that directly affected her now, was it? As she rounded another corner, she stood before the bridge that led to the gardens of Canterlot Castle. The castle itself looked exactly as she remembered it from her youth. Standing tall against the skyline and nestled against the side of the mountain, it was a spectacle to behold. But in the eerie silence of the strange holiday celebrations, it seemed a little more foreboding than before. Starlight pondered if Twilight had been herded up into the castle as well, of course that was assuming that she'd even ended up in the same place as Starlight. Still if that interfering purple unicorn had shown up, then Starlight could gloat about just how wrong she had been about these alternate futures. Nothing was different aside from a new holiday. She crossed the bridge with confidence and headed inside the castle through the open front door.
Security obviously wasn't a top priority on this new holiday, but then why would it be if everyone was already inside the castle? As she crossed the threshold, Starlight instantly recoiled, scrunching up her nose at the smell. The odour came in waves, washing over her body in bitter pulses. Her nose burned and her throat grew sore as she breathed in the heady scent. Even with the fresh air coming in through the open door, it wasn't enough to dissipate the scent. Starlight kept a hand to her nose as she ventured inside, trying her best not to think about it. However, the closer she got to the Royal Chambers, the stronger it got. Her eyes began to water as her mind began to experience flashes of urges and unusual feelings. Crass commands telling her to breed, requesting that she fuck the nearest phallic object. Starlight wasn't a woman of loose morals though, she had enough restraint to resist such flashes. Though the stronger the scent became, the harder resisting those urges were. As she approached the doors to the Royal Chambers, she heard voices that she hadn't heard since phasing into this future. Those same voices that had moaned the name of the Solar Princess so desperately, were moaning them again behind the door. Either side of the door sat two guards, dressed in their fabric undergarments as opposed to their full guard ensemble. They sat upon small wooden stools, their bellies similarily bloated to those of the guards outside. Their bodies reeked of sweat and the same bitterness that bit at Starlight's throat. What little clothing they had managed to slip into had been soaked through, particularly in the panties. While the stools themselves sat in a pool of fluid which was steadily growing larger as whatever had bloated their stomachs, drained to the floor. Starlight looked on with a mix of confusion and surprise as she witnessed the sight before carefully stepping over the pool and pushing the door open.
As the door shut behind her, she quickly covered her nose and mouth again. The smell now was almost unbearable. The air reeked of salt and it nipped at her exposed skin, drying it out. In the darkness of the room, she could hear those voices again, this time crying out for both Celestia  and  Luna. Each phrase intermittent with pants and gasps along with the sounds of something wet slapping against a surface. The flashes in her head were becoming much louder now, those commands being amplified by whatever was at the end of the darkened room. She stepped forwards, her foot coming down in something warm and wet. She quickly recoiled her foot and put it down elsewhere, only for the same thing to happen again. She danced frantically between puddle after puddle before consigning herself to the fact she'd just have to settle for wet feet. At least whatever it was on the floor was warm and felt pleasant, if a little sticky between her toes. She walked forwards, cursing her decision not to wear some kind of shoes. Her way was illuminated magical torch sconces that lit up as she came within reach of them. Ahead, she could hear desperate pants and frustrated slapping, only growing louder. Just what kind of holiday was this anyway?
Engrossed in the surrounding darkness, Starlight bumped into the first of many stallions that had gathered in a long line in the chambers. The stallion whipped around to see just who had dared interrupt him. Starlight gasped loudly as she saw that the stallion and good portion of those in front of him were all engaged in the same act. Their long, veiny, throbbing shafts bobbed in their hands as they stroked themselves vigorously to the screams of delight coming from further down the hall. Starlight backed up a little bit to avoid getting any of the stallion's heady pre-seed on her body.
"Are you? Should you be? Really?" Starlight asked, struggling to finish any of her questions.
"Where've you been?" The stallion asked, his eyelids fluttering as he crossed over another pre-orgasm peak. "Everyone's doin' it. An' I've got a good reason to do it."
Starlight wanted to stop herself from actually continuing the conversation, but a strange and morbid curiosity was taking hold. "And just what sort of good reason could you have for such debauchery?"
"My wife is down there right now," he grunts, his hand quickening against his shaft, squeezing softly now and again. "With the Princesses, getting pumped so full with their glorious seed. She's sure to be pregnant when they're done. She's gonna have a whole mess of young'uns, and none of them are mine! What a-" The stallion convulsed, spinning around and aiming his shaft to the wall. With a guttural roar, he fired his load against the stone, ropes of pearly seed splattering out in all directions. The rest of it drooled down the wall to an unseen grate at his feet, wherever it went after that probably wasn't worth thinking of.
It was then that Starlight realised just what it was that she'd been stepping in since she'd entered the Royal Chambers. Not just the cum from these stallions as they stroked themselves in preparation for the sight of the Princesses, but also the cum that leaked from the mares as well. The floor was awash with cum from both, and, as a parade of used mares walked by, their bellies bulging with seed, Starlight felt like she was gonna be sick. This holiday was nothing more than some kind of debauched sex orgy, the scent in the air was the wafting pungency of fuck fumes from the Royal Sisters and their subjects. She wanted to leave, to run for the hills and  never come back. But her mind was already being infected by the powerful lust of the Princesses and their subjects. The scent of freshly churned cum from the stallion before her already wafting into her nose. The room was practically spinning with the heady mix of sweat, and bodily fluids. She was only brought out of her stupor by the stallion's voice as he stroked his erection back to full mast.
"Can't wait for my turn. How about you?" he asked, his breaths coming ragged and exhausted.
"My turn?" Starlight asked. She hadn't considered such a thing. Why would she? She'd only just found herself what this holiday really was and there was nothing stopping her from walking out.
"Of course, you sure you're all with it? I can't think of anyone who doesn't know what's going on today of all days. Everyone, stallion or mare, are to report to the Princesses on the first of the month to pay their dues. And any foreign dignitaries are to report to the Princesses within five hours of crossing the border to pay their dues. Oh! Is that why you're here? Have you crossed the border?"
"No, I've always been here," Starlight looked away again as the stallion resumed stroking with vigour as a particular voice rang out.
"Oh there she is! That's her, that's my wife. Luna's probably pounding away at her so hard right now. Ooooh, I'm almost ready, Luna! I long for your embrace!" he cried, bucking his hips wildly, legs trembling with excitement.
Starlight had reached the end of her tether with this particular stallion. He was obviously lost to his sexual desire to be ravaged by Princess Luna and would be of no further help to her. She turned around to leave and instead bumped into another stallion, this one much more regal looking than the others. He stood taller than Starlight, his body dressed in the same armour as the guards, though he sported neither the swollen stomach, bandy legs or glazed expression as the others. He was like Starlight, completely in control of her senses, albeit she was slowly succumbing to the breeding ground around her.
"You must be Starlight Glimmer," the stranger began. "My father has been expecting you ever since Princess Twilight informed her of your eventual arrival."
"Your father?" Starlight asked, glossing over the mention of Twilight for now.
"Princess Celestia," he continued. " My mother is Princess Luna, in case you were going to ask about her. I'm a product of this special day, of the first instance of it no doubt. Back when Celestia and Luna were testing out the finer details if the day between themselves. My name is Auric, and it's a pleasure to meet you."
Starlight shuddered to think of the Princesses sleeping with each other. It just wasn't right and certainly wasn't a thing back in her timeline, was it? "You mentioned Princess Twilight, is she here? I expect she's whispered things in the ears of the Princesses about me, hasn't she? About what we're doing here, no doubt and who I am."
"You understand her well and you are correct. In fact, the Princesses have asked that you be brought before them right away. Skipped right to the front of the line for a special meeting with them," Auric replied. "If you'd like to follow me, I'll show you the way."
Starlight was dubious about the intentions, given what she'd seen and heard of this day so far. "Lead on then."
Together, the pair walked alongside the line of stallions and mares as they waited to be taken for a ride by the Princesses. Several times, Starlight had to duck and contort her body to avoid falling foul of an errant rope of cum. 
"I apologise for the regulars, they can be a little randy while they're waiting for their turn."
"Yeah, I've noticed. There was a guy back there, said he could hear his wife from back there, and he was incredibly excited about his own time with Luna."
"Mother is popular. Especially with those who've had her children and seen them grow up to become a part of the Royal Guard. I don't know what it is, but her seed seems to be breed excellent guards. While father's can be a little...hit and miss. Though, do not tell her I said that."
The pair continued in silence along the line, the sounds of pleasure and delight only growing louder and more intense. Several of the mares that had been used by the Princesses lay in their path, their bellies filled to bursting, their legs unable to carry them any further. Starlight almost tripped over one of them as they reached the front of the line, the mare gurgling and grunting in response. At the end of the chamber, the space opened up and Starlight was greeted with a sight that made her jaw drop right to the floor. There was not a single patch of flooring that was not covered by the bodies of a mare of stallion that had been ravaged by the Princesses. The floor writhed with their pained movements, though not one of them complained. They simply gurgled their delight, occasionally muttering a praise for the Princesses and thanks for their donations.
"Oh, Auric? Is that you? Do come closer, let me see you a little better," came a voice from the opposite end of the room.
"Of course, mother," Aurice did as he was told and stepped carefully over the heaving bodies of Celestia's and Luna's fuck toys.
As he walked towards the voices, the torches on the wall illuminated to show two thrones, each one filled with the form of the Solar and Lunar Princesses. The throne on the right contained that of Princess Luna. Her midnight blue form sat with her left leg resting over the side of her throne. Stood either side of her were two of her guards, their deep blue armour long since discarded as they suckled and nursed from Luna's engorged nipples. The Princess of the Night patted their heads as thanks for their work, while a little further down, two stallions kneaded Luna's tremendous balls. Each one the size of overinflated beachballs, hung lazily against the legs of the throne. The rumbling of seed churning and roiling within those inflated orbs, each gentle caress sending twitches up Luna's shaft. Starlight spared a glance upwards, a lump forming in her throat as her eyes drew themselves higher and higher. Until they even looked over Luna's head at the monstrous meat that had been slung over her shoulder and the back of the throne. Another member of the harem of depravity stood behind the throne, bestowing licks and rubs to the shaft, focused primarily at the head. No doubt preparing Luna for her next conquest, whoever that was going to be. Starlight could smell Luna's arousal over everything else in the room, which was impressive consider the sheer potency of smells wafting up from the used mares and stallions. Auric approached the throne, bowed his head and stepped up to sit on Luna's lap. He snuggled himself in between Luna's grotesquely oversized shaft and her right breast. There was just enough room for him as he shunted Luna's bountiful boob over to the side and snuggled into her cleavage.
"My, my, my, Auric. You seem to get bigger every time I see you!" Luna exclaimed, her hand quickly reaching down to expose Auric's crotch to the audience. A few deft motions of her hand and Auric was putty in her fingers, his shaft springing to attention.
"I've brought you the one known as Starlight Glimmer, she was waiting in line with the others. I hope you don't mind the interruption to the schedule."
"Oh, I wouldn't worry about that, Auric. I daresay she'll liven up the proceedings a little anyway. Isn't that right, Starlight?" came a voice from the other throne.
Starlight turned her head to the left to see Celestia sitting in quite the same way as her Lunar sister. Her leg propped over the side of the throne, her pendulous balls on display and being serviced by two lucky subjects. Her breasts and shaft were far bigger than that of Luna, with both her mounds hanging over the edge of her seat in both directions. Her shaft hung over the back of the throne, just like Luna's, but the stallion servicing it needed to kneel to reach the tip. But it was the rest of Celestia's body that was the most drastic change when compared to her sister. Her hips barely fit in her seat, glorious white flesh spread over the arms of the throne. But there was one more difference that made Celestia stand out from that of her sister. That was just how much further her legs and upper body extended beyond the confines of the throne. From Starlight's best guess and the distance between then, Luna must have been around seven and a half feet tall, but Celestia, she must have been around nine feet tall. Starlight felt dwarfed in comparison to the two Princesses at her underwhelmingly average height of five foot and six inches.
Starlight shuddered, she almost missed the sound of mares and stallions being used and abused. The long silences felt scarily empty. "There's....there's a stallion back there," Starlight gulped loudly, that lump in her throat seemingly growing bigger. "He was  enjoying  this, well, the sounds of his wife. Is she here? His wife, I mean."
"You almost tripped over her as you came in," Luna replied, before giggling to herself like a child.
Starlight spun around to gaze at the mares that lay behind her. One in particular stood out from the rest. A dazed, blue, mare lay face down in a puddle of ejaculate. She was breathing, but one had to wonder for just how long given her airways were currently taking in more cum than air. Starlight hopped over the other mares and knelt down beside the stallion's wife, turning her head sideways so that she could breathe again. "This is her? This is the one that he's fantasising over out there? And you just left her like this?"
"Poor thing," Luna continued. "I filled her up so fast."
"More than her husband ever could!" interjected Celestia, causing a fit of laughter from the pair.
"Did you hear that?!" Luna shouted, her words bouncing down the line until they found their mark. "Your wife screamed like a pig and couldn't even take a tenth of my load! But she couldn't stop saying how it was the best fuck of her life!" There came a delighted gasp followed by the echoed cry of  Praise Luna! , even his wife muttered the same phrase into the puddle of cum.
"Any further questions?" Celestia asked, indulging Starlight's curiosity as her member began to throb and swell to attention.
"Auric, he said he's your child and that stallion back there, he said his wife will be pregnant. Are..." Starlight shook her head. "Just how many of those here today are descended from this debauched holiday?"
"Half the kingdom, give or take a few test cases. Cases like Auric, or any of our most faithful attendants that you see here."
"Of course, it's to be expected when you take into account just how difficult it is to drain these balls. There are days when I feel like I won't last until the start of the next month. But with Auric and my most loyal and faithful attendants," She paused to gently stroke her hands through the manes of her breast devotees; while simultaneously rubbing the cheeks of her ball worshippers with the soles of her feet. "We get enough relief to pass the time by.  The guards often help too, as I'm sure you're aware."
"Yes, I've seen their contributions," Starlight replied, reminiscing for a moment about the guards the guards she'd seen at the door and out in the street. Suddenly she realised that something was missing from the scene, or rather, someone. "Where's Twilight? Auric said she'd spoken to you, but I didn't see her on the way here, and I certainly don't see her now."
Celestia sighed as she waved off her attendants one by one. "She's in my private quarters, currently undergoing the typical Alicorn transformation. I must say, it was quite a surprise to see her so...plain. Hardly any breasts to her, hips as flat as a board and not even a stallionhood and a pair of balls. I was almost certain that I'd given her those the first time, still! It'll be nice to have a third Princess to speed things along, wouldn't you say, sister?"
"Oh, of course," Luna followed suit with her sister, waving off her attendants and whispering something to Auric to get him give her space as well. "Now, speaking of moving things along. I believe we're starting to fall behind on schedule. Shall we get back on track?"
Both Princesses rose from their thrones, shafts having stiffened enough to stand on their own. They moved with a peculiar swiftness, their oversized genitalia proving no hinderance to them as they strode across the room. Bodies of mares and stallions alike were smothered under their balls, drenched in that musky aroma for just a few precious seconds. Upon understanding what their approach meant for Starlight, the pink unicorn began to step backwards. Behind her she could hear whispers from the stallions in line, talking about how lucky she was. Starlight certainly didn't feel lucky, she felt like she was in the middle of a waking nightmare. She took a step backwards and failed to notice the stallion's wife who had stuck her arms out to trip Starlight up. As she stumbled and crashed against the swollen belly of another mare, she heard the whispered cries of  Praise Luna!  and  Praise Celestia!  begin to grow louder around her. She tried to scurry away, but the mares at her feet held onto her legs with what little strength they could muster. Starlight kicked and struggled but it was too late, the towering forms of both Celestia and Luna were upon her, shafts bobbing heavily at their waists. Starlight felt the grip of their magic on her hands and feet, lifting her up into the air and spinning her around to her front. There was a quick flash of magic and Starlight felt a cooling breeze across the entirety of her body. She was naked, her clothes zapped from her body by one of the Princesses.
"I must say," Luna began as she stepped over her previous conquests until her balls rested against Starlight's chin. "It'll be something of a treat for us to use someone new, wouldn't you say, sister?"
Starlight felt a breath at her nethers as Celestia inspected just what she had to play with. "Of course, sister. From the looks of her, I'd say this one has never felt her own touch, let alone the exhiliration of being properly filled." A collective moan from the other subjects drowned out the rest of Celestia's words.
The heat from the pair was incredible, like being out in the blazing sun of a glorious summer's day. The only difference being that those days didn't smell of the built up sweat and musk from hours of cum-stained pleasure seeking. Starlight wanted to cover her nose, to ward off the scent as it permeated her nostrils, raging through her sinuses and into her mind. Those flashes from before returned, this time they had faces attached to them. Celestia and Luna were in her head, drifting around her consciousness, speaking that same mantra.  Fuck.   Mate.   Breed.  Their shafts and balls were there too, glistening and slick with the bodily fluids of countless conquests. She couldn't escape the pair, no matter how much she tried to force those ghastly apparitions out of her mind. It certainly didn't get any easier when she was raised up to those swollen tips of both dicks. Magic gripped at her jaw and legs, spreading both of them to ensure she could properly take them. Both Princesses grunted with impatience, thrusting their hips forwards to illustrate their need. Starlight tried to call out a final protest, but it was quickly drowned out by a sudden intrustion at her rear.
Celestia showed less restraint than that of her sister and forcefully shoved her cock cannon between Starlight's legs. The pink unicorn screamed as pain tore through her lower body, her cherry well and truly popped. Luna was quick to jump in and silence her screams, muffling them as she shoved her own shaft down Starlight's throat. The whispers from the crowd turned to cheers of shock and amazement. Never before had the Princesses double-teamed someone and quite frankly a lot of those waiting for their turn were jealous that Starlight was the first. The unicorn herself would much rather someone else be in the middle of Luna and Celestia's spitroast. Her lower body had gone numb. The pain that had initially come with Celestia's rough intrusion into her most intimate area had long since faded. All that was left was the feeling of her insides being rearranged as Celestia and Luna's shafts kissed around her stomach. The two grotesque bulges bouncing off one another as the pair ramped up their desperate attempts at release. With each rhythmic thrust of their hips, Starlight grew more susceptible to the mantra in her head. To the ideal that she should simply give up and accept her new place in society.
"Oh sister! You simply must sample Starlight's marehood, I've never felt one as tight as this! So virginal! So pure! It's a delight to stretch it to an accomadating size!" Celestia exclaimed, pulling back on Starlight's legs to impale her right to the hilt.
"Her throat is just as good, sister! The way she gags for breath, her throat closing tightly around me, that alone could finish off a lesser mare!"
The attendants that had been dismissed from the sides of the Princesses soon returned to prepare their Mistresses for cumming. It wasn't totally necessary, but the Princesses weren't going to complain about the extra effort. They leant in to massage their swollen balls, gripping and stroking at every inch of flesh to coax the Princesses to release. Their tongues ravished the saintly sacs, savouring the taste and texture, basking in the warmth their antics afforded them. Nuzzling and stroking as the seed insde churned and swelled them outwards. A load of tremendous proportions was being readied to dump into Starlight and the poor unicorn had no idea it was coming. Her only indication were the increasingly more guttural moans from the pair over the sounds of dampened flesh slapping together.
"Oh sister, I believe the time has come!" moaned Celestia, her thrusts quickening so much that her plump butt sent an attendant hurtling to the ground. 
"So soon? You must be desperate, sister!" Luna forced her cock as deep as it could go in Starlight's throat, reducing her thrusts to short, rapid bursts. "Let her have it!"
Starlight's body was on fire, the warmth from the two shafts was enough. But as she felt the bulges of seed force their way up the two cocks, it felt like an inferno had been lit inside her. When the bulges reached the cock tips and messily ejected themselves into Starlight's stomach and uteral passage, she cried out around Luna's cock. The Princesses squealed with delight as Starlight's stomach began to bulge in two places. First it was nothing more than a few inches, enough to be mistaken as a bit of overeating. Then with each subsequent spurt it began to bulge more obscenely. Within seconds she looked like she was pregnant and from there it just looked like she'd had another child added to the litter. The attendants around her gasped and muttered their own praises, both for their hard work and the load the sisters were releasing. Starlight's eyes rolled back in her head, she was going to pass out. Her stomach was so bloated now, easily akin to that of triplets. The Princesses showed no signs of slowing down either. As her stomach swelled enough to give the impression of quintuplets, she was allowed some relief as Luna began to back out. Starlight let out several ragged breaths as her airways were cleared, clear liquid bubbling up and gurgling in her throat as she did so. There was a final gurgle from her stomach as Celestia unloaded her last and pulled out. Just like her sister, she was still sporting an incredible erection, standing tall and proud with a clear drool connecting it to Starlight.
"I...thankful...it's," Starlight gulped, swallowing the liquid blockage in her throat. "...Over."
The Princesses pressed the flat of their palms to their mouths and chuckled to themselves. The chuckling soon turned into a roar of laughter, even the attendants joined in as they lapped up the mess that had pooled underneath Starlight.
"Oh, it's not over yet, Starlight Glimmer. Not by a long shot," Luna started.
"My sister is correct. What you are full of, what has given you such a magnificent and swollen belly, is nothing more than our bountiful pre-ejaculate. Pre-cum. Lubrication. Whatever you choose to call it." Celestia interjected.
"Wh-what? B-but you said-" 
"That the time had come? I did say that, didn't I? Of course that had nothing to do with orgasm, mearly that the process had been completed," replied Luna, stepping off to the side to give Starlight a view of what was behind her.
"Process?" the unicorn asked, before her eyes came to a rest on what had been hiding behind Luna.
"Hello, Starlight. Are you enjoying your equality?" came a voice that Starlight had hoped she'd seen the last of.
Standing behind Luna was the newly transformed form of Twilight Sparkle. Her eyes glowed with a golden hue, implying that her mind was not completely her own. Her body had been swollen, particularly in the hips and butt, while her breasts remained more or less a step above mosquito bites. But like Celestia and Luna, the most important part of the whole show was the gargantuan princessly prick that stood tall from her waist. Thicker than both of her arms placed side by side and taller than her chest, with its entire length slickened with pre-cum. Her balls swung below the mammoth shaft with pendulous force, her every step closer slapping them off her thighs. Waves of lavender wafted over across the humid, sweaty air, and as far as Starlight was concerned it was the closest thing to a breath of fresh air. For a few moments, Starlight was able to leave the lowly lit chamber and escape to somewhere better. Somewhere where she still had a purpose other than being a cocksock for the most powerful creatures in the land. But when she felt a familiar rubbing at her nethers, she was brought right back into that room of depravity.
"Equality?!" Starlight yelled, having recovered more of her voice. "What's equal about this? Everyone is just-"
"Used the same? Yes, everyone is used equally for our benefit. Isn't that the same system you had in your village?"
"I-"
"That's enough out of you, Starlight," Luna interrupted. "Sister, Twilight, if you wouldn't mind, could we get on with it? If I have to wait any longer, I'm going to get a serious case of blue balls."
" Bluer  balls, you mean, sister."
Luna gave a snort of derision as she shifted in place, her balls rumbling fiercely as if to make a point. "Shall we?"
Both Twilight and Celestia nodded before getting themselves into position. Twilight crawled along the floor, rolling onto her back and readying her shaft at the entrance to Starlight's vagina. She winked at Starlight from below her, raising her hands up to softly tug at Starlight's exposed nipples. Starlight shuddered and shivered, held in place by the magical grip on her extremities. Twilight continued her tweaking, while her shaft pulsed greedily against Starlight's nethers. Just above her shaft, Celestia's own cock was primed at the tight passage of Starlight's anus. The previously unused passage was like another virgin cherry just begging to be popped by Celestia's mammoth meat. With Luna already taking the lead and silencing Starlight by filling her throat once more, Celestia and Twilight joined in with a soft thrust. Though given the thickness of their shafts and the narrow and tight space of the entrances, all they succeeded in doing was forcing Starlight deeper down Luna's cock. The Princess of the Night let out a shuddered moan as the pair tried for a second attempt. This time, with much more force. With a satisfying cry of agony from Starlight, the two shafts wormed their way inside their respective orifices. Tears welled up in Starlight's eyes as the two phalluses felt like they were tearing her innards asunder. Her pained grunts and clenching of her teeth only served to fuel the randy Princesses onward. Luna showed delight at the pressure being exerted upon her, thrusting her hips up and down to make Starlight bite harder.
Underneath her, Twilight was focusing most of her attention of working in tandem with Celestia's thrusts. When one was pulling out, the other was ramming right back in and vice versa. They could feel every vein and on each other's shaft through the walls of their respective orifices. The flesh inside was strained so tightly that it was like both cocks had been forced into a single orifice. However, as glorious and delightful as it was, Twilight spent the rest of her attention of Starlight's breasts and swollen stomach. Like a child with a toy, Twilight swilled the contents of Starlight's stomach back and forth, watching that taut flesh wobble and shake. There was even the slightest shudder as Starlight drew in whatever breath she could get. The sloshing of the fluids inside felt good against her dick as waves washed to and fro inside her little toy. But the best part of Starlight? For Twilight, that was definitely her breasts. Twilight took great pleasure in milking Starlight like the sex-starved cow she wanted her to be. Taking fistfuls of flesh in her hands and tugging downwards, as though she was milking the udder of a cow. Starlight squealed around Luna's cock, her eyes growing wide in shock and surprise before rolling back into her head. Twilight was ruthless in her machinations, tugging down enough to stretch the breastflesh to its limit. Then, when Startlight couldn't squeal any harder, she'd release it, just for a second, before clamping down hard on the nipples. The thick, dimpled flesh was just enough to fit between two of Twilight's fingers, perfect to be pinched and teased. Tears welled up in Starlight's eyes and streamed down her face as Twilight went to town on those purple nubs.
Starlight was at the end of her tether, with the three fat pricks inside her body and the full frontal assault from Twilight below, she was ready to give up. Her mind was on the verge of breaking down, so close to snapping completely and letting her give in to the urges welling up from within. The sensation of a spring being pushed down and down in her stomach had reached a point where it was becoming painful. She wanted so badly to release, but each time she felt close, Twilight, Luna or Celestia would change  their pace and prevent her from doing so. Beads of sweat formed across the length of Starlight's body, matting her fur. Along with the blush forming across her cheeks and the glazed look in her eyes, it was clear she was losing control. Her thoughts turned increasingly to the princess peckers ploughing her pink posterior. To the cum they would innevitably fill her up with. From there it was a short trip to the possible pregnancies she'd experience. The children she'd bear and bring to term, what would they look like? The more she thought on it, the more she understood the holiday, this blessed moment where the Princesses secured the future for Equestria. This was what equality felt like, everyone coming together to benefit the whole. This was what she was missing in her old timeline.
A grunt from behind roused Starlight from her thoughts and a familiar warmth spreading through her stomach. Celestia, much to the delight of her younger sister appeared to have finally had enough. With a single thrust, Starlight's stomach began to bulge once more. Rapidly expanding out and pushing down on Twilight. There came a purring gasp of surprise from below as Starlight's belly came to rest upon Twilight's own stomach. This only spurred the lavender Alicorn on, her thrusts increasing in pace to make up for Celestia's lack. Sweat rained down upon Twilight, but the princess simply drank it in and continued unabated. With her stomach now the size of an inflated beachball, around the same size as the balls of the Princesses, Starlight was completely lost. Her tongue thrashed underneath Luna's cock, her eyes had become cold and lifeless. She existed as nothing more than a toy to be fucked relentless, and she knew it. That mantra that had been racing around her head spilled out of her mouth in muffled pants.
" Fuck.   Mate.   Breed. "
"Hear that, sister? Looks like your load finally broke this one. I can hear her begging around my cock," Luna panted.
"Oh? Well, let's see just how much of a slut we can make her. I'm far from empty!" Celestia gloated.
"You'll save some room for me, of course, won't you?" Twilight asked, poking her head out from below Starlight's armpit.
"No promises! If you want to get your fill, you'd better be quick about it!" Luna replied, quickening her hip thrusts.
Twilight, not wanting to be left out from the fun quickened her pace as well. Though she had an ace up her sleeve. She could feel just how desperately Starlight wanted to have an orgasm of her own and how much the constant filling was stopping her. So, ever the benevolent force as she was, Twilight decided to help her. She milked her cow for all she was worth, tugging at her plump nipples like it was going out of fashion. Starlight thrashed her head, snorting and breathing through her nose with reckless abandon. Twilight felt the unicorn's pussy tighten up around her cock, before a torrent of Celestia's cum, her own pre and Starlight's own ejeaculate splashed into the open. What didn't splatter against the floor drooled onto Starlight's stomach, eventually onto Twilight and then the floor. There was nothing to stop the newly christened futa, Twilight Sparkle from unleashing her load now. Not even the vicelike walls of Starlight's ex-virgin pussy would hold back the flood. She reared her head up and bit down hard on Starlight's nipple as her seed exploded into Starlight. Within a matter of seconds, Starlight's belly doubled in size, spilling over Twilight's thighs and encroaching on her upper body. 
As the swelling forced Starlight upwrds, Luna seized her opportunity to cum before Starlight got out of her reach. The Lunar Princess pushed herself right up to the hilt, bouncing against Starlight's muzzle with enough force to do damage at a sustained length of time. Her balls rumbled fiercely as they unloaded thick, baby batter into Starlight's stomach, which when combined with Twilight's load sent Starlight shooting for the sky. There were cheers and orgasmic moans from the ponies in waiting, and dull chants from the used ponies. As Starlight ballooned higher, each of the Princesses moved from shooting their load inside and focused the rest onto the outside. Twilight was first, having to lift scoot herself out to avoid being smothered under pink belly. She managed to fire an errant rope of cum onto both Luna and Celestia before painting her initials onto Starlight's stomach. Next up was Celestia, who spent the rest of her load painting both Starlight's anus and vagina. Last to leave the warm confined of Starlight Glimmer was Princess Luna, the last to start cumming and the last to leave. She painted a beautiful white glaze over Starlight's face, offering up the lewdest facemask around. Her seed was so thick and heavy that Starlight was left unable to open her eyes, until enough cum had slid down and off her face.
"Hah, hahah, what a fuck!" Luna exclaimed. "Never, in all my years, have I had the pleasure of such a throat! Truly the one to beat!"
"Her every orifice is so wonderfully tight and she closes up again just enough to make herself feel virginal every time!" Celestia agreed. "You, Starlight Glimmer are going to remain here."
"Certainly, sister! I've been hoping for a personal cum dumpster for quite a while. Even the attendants grow too loose over time."
"Twilight? What do you say? Does Starlight fulfill your needs?" Celestia asked.
The lavender Alicorn smirked, the golden glow in her eyes swelling brighter for a second. "Of course. I'm happy to remain here and keep filling  our blimp of a cum cow until she bursts!"
"Excellent!" replied both sisters. "And what say you, Starlight?"
Starlight drooled cum, it bubbled out from either side of her mouth. "C-cum...pl-please," She whined. "C-cock.  Fuck.   Breed.   Please... "
"Now, while our newest fuck toy drains for round two, what say we work on this queue?" replied Celestia as she strode back to her throne, her cock already hardening again.
"Indeed, sister. Come, Twilight," Luna strode to her throne, taking her seat with Twilight at her side. She smirked at the swollen, pink, pony balloon at the centre of the room and called for a new fuck. "Next!"
