Applause rang out in line to Twilight's cries, at least from Rose, Nightmare Rarity, Spike and Luna. Chrysalis, Nightmare Moon and Daybreaker however had venomous glares that all promised various depraved tortures on Twilight and Celestia when they were victorious over the other in their challenges. Yet they were powerless to change the facts, the Slutprincesses had won the challenge.

"That was excellent, Celestia." Rose said, clapping faster than any other there. The pink-skinned hybrid's face was blushing a bright red, and a trail of perverted drool had dripped down her skirt. "The way you made Twilight cum with just your words alone, and your sinister manipulation of the Sparkle family was so...so fucking hot. Was it all true?"

"Of course it was, Rose." Celestia purred, smiling like one would smile at an eager student. "It's been a personal pet project for mine for quite some time. Perverting Silk Sparkle's dynasty for generations to come, and as a bonus I got this wonderful slutty protege."

Celestia's fingers delved particularly deeply into her student's pussy, who had now been fucked into a stupid stupor and could only let out a groan of joy. Her eyes had rolled back into her skull as her mind was now awash with fantasy after fantasy of her family's new history, each idea she loved more and more. Celestia, very pleased with the results of her new student, simply smiled.

"As hot as this is, Master, it may be time to recombine the two Twilights, or else we'd risk too much divergence and individuality." Nightmare Rarity warned to her Master, her head bowed gracefully, eyes glinting with awe.

"Yes, yes, you're right, Nightmare Rarity, go ahead," Rose said, with a dismissive wave of her hand. Nodding, Nightmare Rarity stepped forward and lifted the two Twilights with a lift of her hand.

"Do not worry, Mistress Twilight, this will not hurt," she said, before she brought the two Twilights together with a flick of her wrist. In a flash of purple light, they soon became the same single Twilight once more, leaving the youngest of the Slutprincess's on the floor, clutching her head.

"Wow, that's... a little disorienting, if I'm honest," Twilight said, rubbing a temple with her fingers.

"I suppose it would be, my deepest apologies. But I imagined you would prefer to keep both the memories of being fucked by Daybreaker and mindfucked by Celestia." Nightmare Rarity explained, a tinge of sincere remorse on her lips.

"Yeah," Twilight said, a horny smile spreading across her face at the thought. "I guess I would."

"Enough of this!" Chrysalis barked, marching over and snapping her fingers impatiently. "There is still one challenge left, and I for one cannot wait to see these two alicorns-" She pointed at Celestia and Luna. "-turned into the personal sex sluts of their hated alter egos."

"They haven't won yet." Luna reminded the Changeling Queen.

"Nor will they at this rate," Celestia purred, fingers trailing down her lips which had shaped into a coy smile. Particularly when Daybreaker gnashed her fangs at Celestia.

"Well, we won't know until the next challenge happens, so, Rose?" Spike turned to his daughter who nodded. She held herself with much greater confidence than she had before, not least of all when she saw her Master smiling.

"The final challenge will include all four of you. You're going to be put under a spell together that will prevent any of you from cumming, unless our Master is the one to fuck you." Rose said with a demure smile towards her Master who smiled savagely. "During the challenge, the losers of the previous challenges will be eating out the winners of the last challenge, the winner will be the side that is the one who holds out the longest and is the last to beg for our Master's cock."

"Seems like an edging contest, though what will make the losers start begging?" Rose's wonderful Master asked, but thankfully, Rose already had an answer for it.

"It'll be a feedback loop, Master." Rose explained before she cast her own lust magic upon the four alicorns. Two spells in particular, one to restrict their orgasms, cursing them to be denied release until they surrendered to their Master's cock. The second spell to create a feedback loop, the more Luna and Daybreaker ate out Nightmare Moon and Celestia's cunts, the more they would feel the pressure themselves. "The more they fuck the other, the more they'll feel it themselves. A difficult balancing act the alicorns will have to walk down."

"Sounds like fun." Her Master smiled, she could see his own erection growing harder now. Stars, his bitch breaker cock was truly magnificent, truly perfect. How wonderfully would it fit down her throat, it was such a wonderful shape. As if it had been made for her throat, or perhaps Rose's throat had been made to fit it.

"ROSE!" Her Master barked, snapping her out of her trance.

"Sorry, Master." Rose squealed but her Master was grinning. She turned back to the four alicorns, all of them taking their positions, each of them with determined glares on their faces. Nightmare Moon looked determined to crush Luna between her thighs whilst Celestia was still smiling smugly at her counterpart's sneering face. "Um... begin!"

The four alicorns wasted no time, the losers thrust their mouths deep into the winners' pussies, both sides eager to break the other in an early win. It wasn't just about strategy, but about proving to their Master that they were worthy and prized fuckdolls who deserved to hold the title. They couldn't just win, they had to show their Master that they had conquered the other.

But neither side was close to giving up the fight. Luna and Daybreaker were both savage in their cunnilingus, both being all to desperate to make up for their previous defeats at the other's hands, but neither Celestia nor Nightmare Moon were going to surrender their progress all too easily either. It was a battle of the gods, and they were all bringing their all.

"You'll pay for your deceit, Nightmare Moon. Soon all our loyal whores will see you at thy knees before me. The Slutprincess's royal whore!" Luna declared as she paused to take the briefest of breaths.

"Hardly likely if you waste that tongue of yours talking rather than fucking." Nightmare Moon jeered, mockingly running a hand through Luna's magical mane like she was a child. "Is that truly the best you've learned since our time on the moon? We're disappointed."

Fury gave way to action as Luna redoubled her efforts, her tongue exploring deeper into Nightmare Moon's clit. She pushed through her own mounting lust as she was determined to make Nightmare Moon pay for her treachery in the first round. Her colossal, glorious ass swayed from side to side in a desperate attempt to work off the energy passing through the rear. Nightmare Moon repaid the favour by crushing Luna's face between her powerful thighs, not making Luna's task any easier.

Meanwhile, with the other pair, the two solar alicorns were sizing each other up. Daybreaker's body was cushioned upon her gigantic breasts, and Rose wondered if those colossal mammaries would be enough to support the dark alicorn's entire weight. Celestia was looking down at the solar alicorn with a dismissive sneer, flushed from her previous victory.

"What's the matter, Daybreaker? You always said you were more powerful, beautiful and intelligent than me, yet here you are, afraid." Celestia sneered, her warm mask of comfort had been replaced with a domineering grin. This was her element, abusing her power and responsibility as an alicorn for her own erotic delights and her Master's will.

Daybreaker bore her fangs, the sting of the previous defeat still fresh in her mind. "Your whore of a student was the only reason I failed, this time she's not here to give you the win."

With that, Daybreaker pounced like a wild beast. She was savage, her mane a blazing inferno of fury. She like Luna opted to simply push past the arousal seeping through her body and do everything she could think of to break Celestia's spirit. But that spirit wasn't close to breaking any time soon, the smile on Celestia's face was proud and serene. Her body arched backwards as Celestia simply allowed her body to be edged to the brink, riding the aroused high.

"Fuck, that's the best you can do? I can barely feel it, slut!" Celestia cried, with a mocking laugh that made Rose just gush. She had thought that Daybreaker was the evil version, yet Celestia was showing a dark side that was making Rose question that assumption and was making her pussy slick and wet.

"Fuck you, you fat-assed whore!" Daybreaker cried, furiously pushing her tongue as deep as she could possibly reach. Her burning mane flared out like an inferno, her efforts redoubling.

"Yes, you will." Celestia sneered, her voice filled with malicious triumph. These were the moments she lived for, putting down the benevolent mask and reveling her true sexual tyrant self. And she could see that she wasn't the only one being entranced by her true self.

Rose's hands had moved on her own, and the dracony had only noticed that they had slipped under her dress when her fingers traced over her G-Spot. "Fuucckkk!"

"Seems my daughter's pretty horny herself." Her Master said with a grin as wide as his face, the tone of his voice teasing like a father showing his daughter's baby pictures. "You really do have a thing for the diabolical women."

"Yes... well, I had my mother to look up to." Rose admitted turning to her Master and she was taken aback by just how long, hard and virile her Master's dick was now that it was free. It was truly perfect, big enough to break any bitch that her Master so deemed, and virile enough to ensure that those women would always be satisfied. "She told me all about how she conspired to ensure both you and our Mistress would embrace our Diamond Queen's vision. How she corrupted all your Ponyville friends and laid the foundations for your harem empire. I suppose hearing that sparked something in me?"

"Funny how that works. I can imagine that Cadance was pissed with how that turned out." Her Master Spike said, eyes flickering towards Chrysalis, who simply folded her arms over her enormous breasts and shot her Master a proud smirk.

"What?" She asked, in mock innocence. "As if you don't like seeing your daughter turned into this malevolent pervert. Speaking of which."

[Derpibooru: 3383286]

Chrysalis grabbed Rose by the back of her head, handfuls of silky violet hair between her fingers, and forced her face down on her Master's cock. "When your Master shows you his cock, it means he wants you to take it, bitch."

Rose put up no resistance, her body trembled under Chrysalis's slightest touch and she found herself melting from the ecstasy of the dual waves of pleasure both from Chrysalis's hand on the back of her head as well her Master's cock down her throat. And what a cock it was! It was as if her throat was made for this, and in some ways, that was absolutely correct.

Behind her, she could hear the pained howls of the four alicorns, and at that moment Chrysalis's plan became clear. Rose could just imagine the four pairs of divine eyes watching her devour Master’s cock, their stomachs twisting with envy and their eyes narrowed with fury. That envy started to bite at the stubbornness of their will, their desperation for their Master's cock was burning away their fury. Far more than any of the fucking from the Alicorns' own sex.

"Looks like someponies see something you like." Master Spike said, his hand rolling through Rose's mane. Another shiver shot down Rose's spine, he was so perfect. His touch, his cock, his everything! There was no greater Master nor Daddy than her Master Spike. Every taste of his pre-cum made her taste buds scream in delight, his hands grasping her roughly, using Rose's body to his pleasure. It was truly heaven.

Tears started to well up in her eyes as she thrust her Master's dick deeper and deeper down her own throat. These were tears of joy for Rose, it was her purpose and her destiny. She could feel her cum dripping down her thighs like a river, she could only redouble her efforts.

"Th-this isn't fucking fair, Master!" Nightmare Moon cried, her deep, regal voice was now quivering with lust. Her body was shuddering like mad now, like a leaf in the wind. Luna sensed this weakness and grinned with a wild savage grin.

"What's the matter, oh evil Nightmare Moon?" Luna asked, pulling back for the slightest moment and licking Nightmare Moon's juice's off her lips. "Are you starting to break? Is eternal enslavement under me a worthwhile price if it means being ravaged by our Master's cock here and now?"

"You've already been fucked by him, we haven't!" Nightmare Moon cried, voice becoming ever more desperate, eyes darting between Spike and Luna. From the corner of her eye she could see Celestia looking upon her with wanton glee, seeing that the Emperess of the night was about to crack.

"Stay strong, Nightmare Moon. I won't be enslaved to this bitch just because you can't keep your pussy in check." Daybreaker warned her counterpart, piercing orange eyes narrowed in fury.

"But-but-" Nightmare Moon whined, unable to stop her eyes from flickering back to her Master's cock. She could see how entranced Rose was by the dragon's cock, how she was driven to worship it like an animal. And the way the perfect rod glistened when covered with the dracony's saliva. For other cocks, it should be a turn-off, no, an insult that Nightmare Moon herself be regulated to sloppy seconds.

But this one was different, it was simply so virile, so perfect. It deserved to be fucked by so many women, it deserved worship and it didn't matter what Nightmare Moon was before its magnificence. With great effort, Nightmare Moon's eyes were torn from the divine mast and into her Master's eyes. Her own midnight eyes were wide and pleading, hoping against all hope that her Master might take pity on her and fuck her without losing the challenge.

But naturally, her Master wasn't so weak-willed as to take pity on a lowly slut like Nightmare Moon, no the only way to that bitch breaking cock was fucking her was under Luna's heels. Slowly, very slowly, Nightmare Moon turned her attention back to Luna who was now eating her counterpart out with even greater savagery. Her beautiful ass wagging like a puppy's tail as she could sense that Nightmare Moon was close to cracking.

"Don't worry, my dear pet." Luna purred, her deep regal voice sending shudders down the evil counterpart's spine. It was really starting to dawn on Nightmare Moon how much confidence becoming the Slutprincess of Whores had changed Luna, her insecurities had vanished and been replaced with erotic confidence. "I'll be a benevolent Mistress, my fine ass will be yours to worship. I will allow you the privilege of dominating a few lesser sluts yourself, provided you make sure that they scream my name, and of course, at the behest of our Master, I will grant you the privilege of having your whore cunt rammed by him now."

"FUUCCCK!" Nightmare Moon howled in both despair and ecstasy. She couldn't resist any more, couldn't resist the temptation of her Master's cock nor the fantasy of being Luna's slave. She would be conquered completely, an extension of the Whore Queen's will, she would still dominate slaves, but now in the name of Luna. "I-I submit. I need his cock, I need it. I surrender, if you let me be fucked by him, then I will be your slave FOREVEERR!"

Filled with triumph, Luna smashed her lips against her counterpart. Ravenous hands betrayed just how horny Luna was right now, and how close she was to forfeiting herself. But this, this was perfect for the Slutprincess of Whores, she could now say definitely that she had conquered her past, quite literally and she would now dominate the night completely.

[Derpibooru: 2203274]

Nightmare Moon wasn't the only one hitting a climax, as the erotic show combined with Rose's supreme skills had brought the harem's Master's cock to its first orgasm to the day. Seeing the kiss between the Slutprincess of Whores and her new slave unleashed a torrent of cum down his daughter's throat. Rose showed her natural talent as a dracony slut by taking every drop of her Master's sperm into her stomach and showed her Master as much by opening her mouth.

"Your sperm Daddy, it tastes heavenly. It's no wonder some worship you like a god, I don't think even a god could make food this good." Rose gasped, the words tumbling out of her mouth before she could stop them, but none of them were anything less than sincere.

"I'm not surprised, and you did a fantastic job getting it out. You truly inherited your mother's blowjob skills, but right now..." Her Daddy turned her attention to Nightmare Moon who had just broken out of her kiss with Luna and was now trembling before Spike, like a mortal about to receive judgement from her god.

"Master..." She gasped, uncharacteristically demure. "We are sorry for our weakness, we tried but-"

She was interrupted by her Master forcing his tongue down her throat. Her Master was not gentle, using the full weight of his strength and power to overwhelm the vain nightmare goddess. She could not resist, for the first time in the dark empress's life she felt truly helpless. Unable to find a shred of will to resist her Master's hands groping fistfuls of her fantastic, glorious ass nor able to muster the desire to fight off Rose as she joined her father taking long sloppy kisses of her nipples.

Nor did she posses any slightest desire to muster that will. The sheer electric pleasure of Master and daughter fucking her was simply too much to ever deny, had her mouth been free, she would have been howling to the skies.

"Oh Daddy, I know her ass is to die for, but don't overlook these dark tits. The just ooze with dark, sensual energy!" Rose cried, her mouth lighting up with joy, like a kid at Hearths Warming Eve. Her frantic hands were eager to help her Daddy enjoy the alicorn's body, Spike himself was giving his daughter a good-natured chuckle.

"Such a little slut you are." He said, smiling proudly, which in turn caused Rose to beam. Between them though, Nightmare Moon was left moaning between their gropes and touch. She could not help but be both tormented and delighted. Delighted to be the object of her Master and his daughter's desires yet also tormented that she was still yet to be fucked.

"So Luna, how do you feel about your new slave?" Spike asked, releasing his grasp of Nightmare Moon to look at her new mistress.

"She is everything I would ask for. Dark yet beautiful with an ass to rival my own." Luna struck the aforementioned rear with a whip of blue magic, sending an erotic howl through the dungeon. "She is the perfect pet, the perfect slave and she'll be of great use entertaining me during our long nights serving the whores of your Empire."

Luna's beaming smile then became sly and devious, and there was a dark glint in her eye that made Rose shiver. "But before you enjoy fucking the cunt of my splendid slave Master, would you permit your lowly whore to use her to break her other dark sister?"

All eyes in the room drifted to the ongoing match between Daybreaker and Celestia, the two now taking a 69 position, with Daybreaker on top of Celestia. Their cunnilingus sessions had slowed when Nightmare Moon had broken before their Master's cock, as she had drawn their attention. Upon Luna's words, the two solar broke away from each other and looked towards their Master. Daybreaker in horror, but Celestia with glee.

Nightmare Moon's face flashed with uncharacteristic horror, a line that even she struggled to cross. But few ponies noticed it as they were taken aback by Rose's maniac glee. "Oh please Master, let her do it. Such a dirty trick, to use one sister to corrupt the other, perfect revenge for Nightmare Moon's trick earlier."

A sweet, melodic yet still villainous laugh echoed through the room from Celestia, delighting in what a pervert her Master's daughter had become. "Oh, perhaps I misjudged you dear Rose, or perhaps you misjudged me. If you truly love sinister perverted women, then I welcome you to join me later. I have a few captives who believe their virtuous Princess will save them from their captivity, would you like to help me break them into true slaves for our Master? Show them the true me."

Rose let out a howl, she may have just cum right then and there. Her head nodded frantically as her knees buckled under her excitement. "Yes, yes, yes please, Celestia! Let's invite Luna too, work together and enslave them together!"

"You have truly raised a wise and virtuous daughter." Luna said with pride, convinced by Twilight that her Master's mission was truly virtuous in comparison to her sister who secretly revelled in her corruption. "We would be happy to do so, but for now we still await our Master's word."

"Well, if Rose here wants to," Spike said, slapping his daughter on the ass. "Then I don't see why not."

"Oh please Master. Let's do it." Rose nodded, her beautiful face gleaming with delight, head nodding furiously. "Luna, use that slave as you wish."

With a beam on her face, Luna snapped her fingers. "Now, Nightmare Slut, climb over your sister. We want your tits over her face and for her to see you cum. Tia, if you would be so kind."

Grinning with unabashed glee, Celestia was able to switch her positions with the grace of a ballerina. Now she was the one between Daybreaker's legs, providing the room for Nightmare Moon to crawl over her sister, the dark slave looking down at her infernal counterpart with a strained lust spread across her face. Daybreaker for her part said nothing, she seemed to know her defeat was inevitable.

Luna, for her part, was also vibrating with emotion, she was now free to cum, free to beg for her Master to give her a good dicking. But she didn't, she needed to break Daybreaker, and she wasn't lying to Nightmare Moon about being a benevolent Mistress. She would not break her word.

Her fingers, cold as the night, spread Nightmare Moon's cheeks as far she could reach. "We are a Mistress of our word, so Master." Luna licked her lips. "Would you take the honour of taking her virginity?"

"Well..." Spike said, raising himself from his throne, a playful mockery of tiredness in his voice. "I suppose I should be a benevolent Master as well."

He lined himself behind Nightmare Moon, the latter bit down on her lip with renewed tightness. Luna and Rose stroked their hands across the Nightmare Goddess, her silky smooth fur receiving their touch as sheer pleasure. Nightmare Moon let out quiet moans to their every touch, but the true pleasure was about to begin. "P-please... Master. Please fuck your unworthy slave. Please fulfil Mistress Luna's request and take my virginity with your power. I have only fucked in dreams, Master, you... you will be the first real cock!"

"If you insist," Spike said, thrusting her cock into Nightmare Moon's anal hole. He wasn't going to pass up the chance to fuck this glorious ass, and as soon as he did so, Nightmare Moon let out of delighted scream, she cared nothing that he was fucking the wrong hole. Either one would beget joy and ecstasy that was greater than anything that Nightmare Moon had ever experienced before.

"F-fuck! Fuck my worthless holes Master, use me as a tool for your pleasure! Fuck my ass to your leisure as your slave bitch Master!" Nightmare Moon cried, her voice shaking with delight. All other thoughts were escaping her body, her once almighty pride, vanity and villainy were lost before the shuddering overwhelming pleasure of her Master's dick.

"Fuck, this ass is tight. Hard to think you're actually a virgin, you must have been tempted over those thousand years. So were you pent up on the Moon? Horny from all the wet dreams you were watching? Bet you're a huge voyeur deep down?" Spike's eyes drifted towards Luna. "Both of you, right?"

"YES!" Luna cried, a hand shooting down her cunt and furiously rubbing it as she watched. "Fuck her good, glorious Master! Fuck her useless cunt like the useless cunt she is!"

"Yes, do it glorious Master! Do as my Mistress commands, I'm hers! I'm yours! I'm your slave!" Nightmare Moon cried, before she broke into her first orgasm. But it wouldn't be the last one today, not when Spike had yet to cum himself, he didn't even break his stride and simply continued. Nightmare Moon didn't take long in order to return to the same state of total lust.

"Stop screaming, you fool!" Daybreaker cried, her voice betraying her desperation. Sweat dripped down her body, her breasts and her whole body. Tortured lust twisted across her face as she was forced to watch Nightmare Moon's face twist from her Master's dick. "It-it's hard enough to keep it together as it is!"

"Then don't." Celestia snapped, grinning from ear to ear at her alter self's despair. "Does Nightmare Moon look upset? Is she unhappy? Would you be?"

"I-I'm-" Daybreaker pined, her catlike gold eyes darted to her corrupted sister's lewd face and Celestia's grin. Nightmare Moon's tongue started to roll out of her mouth as she was fucked into a stupor. "I'll never serve you!"

"Won't you?" Luna asked, stretching a pair of latex gloves over her arms. "We'll change that soon." Luna snapped her fingers at Nightmare Moon. "Slave whore! You are forbidden to cum until your sister breaks."

"Noooooo!" Nightmare Moon howled, her head thrown into the air. Her beautiful aurora mane was now a sweaty mess, her dark skin that glistened like the night sky now was now trembling with lust. Her every aspect of her body was crying out for another orgasm, screaming to submit to her Master's cock. "Mistress, please! Do not torture me!"

Luna shook her head, a sinful smile on her face. "Only Daybreaker can save you now."

Spike growled savagely, the torture apparent on Nightmare Moon's face was intoxicating to watch. A testament to his new power, and the corruption of Luna and Nightmare Moon's prideful fall. He only got faster, his thrusts deeper, his grip tighter, all of this to the greater torment of Nightmare Moon.

He wasn't the only one enjoying it though, to his right he heard another scream of delight. This time from his daughter, now on her knees with her fingers thrusting deep into her snatch as she watched the erotic display with wide eyes. “Yes, Luna! Do it! Make her the final nail in Daybreaker’s coffin!”

“You heard our Master’s progeny, slut. Her order is my order.” Luna whispered into Nightmare Moon’s ear. She gave a desperate howl of compliance before she forced the words out of her mouth.

“Daybreaker, join me. Join me as slaves to the Slutprincesses and we'll be able to serve Master's cock at their leisure. Please, don't resist any more. They're not the weak fools we thought they were, they're dominant, powerful agents of our Master's will. It will be a delight to serve them, so join me and submit." Nightmare Moon pleaded, before every woman in the room chanted the same.

"Submit!"

"Submit!"

"Submit!"

"I-I-" Daybreaker's cat-like eyes darted around, praying for some relief, some help, some miracle. But none was coming, all around her, she found the slaves of her Master's harem all chanting the same thing. This was what they all wanted, this was what her Master wanted, this was what SHE wanted. "I submit. I'll serve Celestia, I'll fuck Celestia, just fuck me, Master!"

"YESSS! Victory, sister!" Celestia cried, released from her spell, she came immediately. Just as she about to cum, Celestia managed to mash her lips against her whorish sister to celebrate their final triumph over the Nightmarish counterparts. Now all that was left was for her Master to claim his reward.

Author's Note

This ending might feel a little rushed, I haven't been feeling well today but I wanted to get this finished. We'll be finishing this arc soon so we'll be ready to move on to the next vote soon enough.

More importantly, those of you over at fimfiction you might not have noticed my blog post so I'm including a link to it here: https://www.fimfiction.net/blog/1055749/should-i-use-ai-images

Long and short of it is that with Ko-FI no longer working (and me giving up on fixing it, and no don't give me suggestions, I don't care anymore) I've now got to pay for future images out of my own image. But for solo SFW images I could use civitai images to compensate, but I know AI art is controversial. The word on chyoa seems to be all for it, but I'm not sure what the opinion on fimfiction is yet. So I want to know everyone's general opinion.

I'll still commission, but they might be supplemented with the images. There's a sample with the link.

Any suggestions, feedback, and constructive criticism are welcome.
