"-a strip off." Rose blurted out before she could risk the words getting stuck in her throat. Not an insignificant risk for the horny alicorn hybrid, she could feel her knees begin to buckle from the twin feelings of anxiety and horniness.

She just couldn't help herself. So many things could have gone wrong and could still go wrong. But her Master had accepted her ideas with eagerness, the Slutprincesses had been brought to heel by her Master and so far, the Nightmare alicorns had not shown any sign of open defiance. They seemed open to their destiny as his slut and slave, to her great relief. If anything, they seemed more zealous than the Slutprincesses, willing to cross lines and limits that neither of them would cross.

What would happen if they did win the challenges? If those lines were crossed? What if Daybreaker was free to break into pony's homes? What if Nightmare Moon was able to make all mares into whores and create the eternal orgy? What would those worlds be like? What place would Rose have in it? Would her Master enjoy that? A depraved dystopia under Daybreaker and Nightmare Moon's heel?

Again, Rose had to be snapped out of her reverie, this time with a sharp, yet pleasurable slap to the ass by Chrysalis behind her. It brought no end to her pleasure, only more delight as the sharp pain became an electric pleasure. "Pay attention, slut, don't keep our Master waiting."

She'd been caught daydreaming again! Electric pleasure gave way to horrified embarrassment, as the blush her cheeks turned to a full face of scarlet. "I'm so sorry, Master!"

Her Master, kind and gracious as he was, simply waved her off with an amused smile. "Don't worry, Rose. Now, tell me about this strip-off."

"Right." Rose looked at her notes and realised to her further anxiety, there was another thing on her list she'd overlooked. "Erm... Master for the slave contracts, we'll need Twilight for it. Since Celestia and Luna can't sign their own contracts, I should have mentioned it earlier, but-"

"Chrysalis, fetch Twilight, she should be at her parents' house. No doubt she's catching up for lost time with her mother." Celestia ordered, with a lazy wave of her hand.

"Do you think I take orders from a fatassed whore like you?" Chrysalis barked, nostrils flaring.

"Do as she says, Chrysalis," Spike said, kicking the fury right out of her sails.

"As you wish, my Lord Master." Chrysalis said turning on her heel, swaying her ass with every step she took. She was sending a message, telling her Master every step of the way what he was missing. Its effect was limited, Spike wasn't missing much, not with him having an entire army of sluts with fantastic phat asses that he could call on at any time. Speaking of which.

Rose took a deep breath. "The first challenge is for Nightmare Moon and Luna, to see which one truly deserved the title of the Slutprincess of Whores. Nightmare Rarity, like we said."

Nightmare Rarity bowed her head before raising her hands. In a truly awe-inspiring use of the Root of Magic's powers, she used Nightmare Moon and Luna's own powers to bring all the other ponies into the dream realm, much like how Luna had done with the town of Ponyville against the tantabus. Unlike Luna, however, Nightmare Rarity showed neither strain nor limit to her use of her powers and could keep such a dream intact forever.

Within the dream world, there were nothing but two stages and rows of seats for an audience. Naturally, the two stages each had a stripper pole, with the moon in the dream world shining on them each like a spot light. Overlooking both stages was a VIP seat for their Master, with enough seats for their Master and the other members of his harem.

"It's a simple challenge, to prove which Alicorn deserves the title of Slutprincess of Whores, they'll each take a stage. They'll each perform the sluttiest dance they can manage and the winner will be decided by either our Master, the audience or whichever one submits first." Rose explained, her voice growing quieter and quieter as each word escaped it. As if her throat was being slowly strangled by the snake of anxiety.

To her great relief, what happened next was neither a dreaded silence, nor a torrent of anger and outrage from her Master or his servants. Instead, she received a raised eyebrow of approval from the Slutprincess of Whores and an ever-so-sexy wicked smirk from Nightmare Moon.

"Oh, this will be ever so fun." Nightmare Moon said with a smirk. Marching to her pole with a confident stride, her phat ass swaying before she squatted down before she pushed it back to her rival Luna. A direct challenge to Luna's anal supremacy. "What do you think, oh Slutprincess of Whores, pimps and other filth? Don't you see something you like?"

[Derpibooru: 3311421]

"Oh, wait before you begin, I should mention that you won't be performing without an audience." Rose interrupted, breaking her eyes away from those glorious moons with no shortage of difficulty. "After all, it's only fair that the whores of Equestria get a say in who their Slutprincess should be, right Master?"

"Indeed it should be," Spike said, waving at Nightmare Rarity to continue and she proceeded. With a simple wave of her hand, she brought all the sleeping whores, prostitutes and sex workers in Equestria into the dream. To their Master's delight, the front row had a few guests of honour including Pinkie, who waved her Master like an over-eager fangirl, Mrs Cake whose initial surprise gave way to a coy smile, and the other whores of the strip club. Spike noted that his daughter, Angel Cake, had arrived in the dream with her half-sister already pressed between her legs, with the cougar whispering dark whispers into the pony's ear. She must have been coming from a dream where she did exactly that, barely breaking her stride in from the new dream, apart from a saucy wink to her Master.

"So, the winner will be decided if either of the mares submit, or by our Master's word." Rose pressed her hand around her Master's wrist as he took his seat. "Of course, perhaps my Master might be willing to consider the opinions of his subjects."

"I'll consider it," Spike said with a smirk before leaning back into his throne. Meanwhile, Luna was making her way to her own pole, the sound of each footstep from her stripper heels projecting confidence to the crowd. The sly smirk she sent her alter-ego displayed that none of this was anything less than deliberate, to which Nightmare Moon responded with a huff.

"Begin," Spike said, his hand raised like an emperor. Both alicorns needed no further order and leapt into their dances with glee. The two were naturally incredible, each displaying their centuries of experience to the crowd and their Master. Each swing of the pole was done with refined grace, with every swing of their glorious rears they did so with both an exhibitionist pride and a Master's skill.

But there could only be one winner, and it was clear who was edging out the win. Luna was far from the same mare that Nightmare Moon had once possessed, she had embraced her role as the Slutprincess of Whore with her arms wide open and it had given her a confidence that Nightmare Moon wasn't prepared for.

"This will be an easy task, won't it, Master?" Luna said, hands on her knees as she danced her phat ass from one side to the other, whilst she offered a wide toothy grin over her shoulder to her Master. "Look at the dark, fatassed slut over there. She's drooling like a waterfall, she does remember she should be dancing right?"

Spike smirked, his eyes glancing over to Nightmare Moon who had been caught in a reverie, entranced by Luna's performance. At least until she was called out on it, and that stare was replaced with a schoolgirl's blush before she snapped back into the dance. "It seems she needed a reminder."

Luna let out a laugh, the sweet melodic laugh that seemed to dance in the air. Renewed enthusiasm filled her heart, reinvigorating her dance with new energy. "So it would seem, but pay her no mind, Master." Her dance led to her leaping into the air with a flip that would show the whole audience a full view down her cleavage, she closed her eyes before losing herself in her dance though she didn't notice a soft magical disturbance in the dream, irrelevant in the ecstasy of her exhibitionism. "She's not worthy of your slightest attention."

[Derpibooru: 1490439]

"That's enough!" Her Master barked, snapping Luna's eyes open with a shock. Her Master had risen from his throne and marched over to the stage, he wasn't happy.

"M-Master?" Luna gasped in a panic, her body now freezing in fear. What could she have done to offend him? All thoughts of Nightmare Moon and the dance were forgotten as she looked up to her displeased Master's face. "W-what..."

The words died in her throat, too jumbled between several different responses that none were able to break free of her throat. She wanted to know what she did wrong, what had angered her glorious Master, what she could do to redeem herself and what she could do to make him happy once again. Her mind too frazzled to think of any kind of answer, she couldn't quite think just wait.

At that moment, her thousand years of experience seemed to leave her and she was a young, naive and shy alicorn once again.

"Kneel," her Master snarled and Luna fell to her knees in an instant, as if her legs had crumbled under her weight. Her Master's cock was brought before her, its huge mast laid inches from her face. This was the cock that she needed to serve, in this moment nothing else mattered. Not her sister, not her whores, not Nightmare Moon nor the title of Slutprincess of Whores, she forgot about all of it. It wasn't her Master, it wasn't his cock and it wasn't her purpose to think about any of them.

"Wrap those tits around it." Her Master said and the Slutprincess didn't waste any time in putting her newly refined skills to work. She put twice as much effort into this titfuck as she would to any other, her desperation to please overshadowing any other concern or thought. If she had been more lucid then she might have noticed that the dick she was wrapping her tits around, whilst superior to any other, (as any imitation of their Master's cock was), did not provide the same unthinkable ecstasy as the real thing. But Luna didn't care about any of that, simply she presumed that it was her punishment to be denied the heavenly pleasure her Master could effortlessly provide.

"Isn't that your rightful place, you self-righteous whore? Kneeling at my feet pleases me, doesn't it?" Spike demanded, and Luna found herself nodding frantically. Anything to please the Master she worshipped.

[Derpibooru: 760295]

"Yes, yes I submit to you. I am your submissive whore and nothing else." Luna pleaded, redoubling her efforts in frantic desperation to prove her submission.

"Yes, you are." Her Master said, but not in his own voice, but rather in Nightmare Moon's. In a single second of utter horror, Luna realised what must have happened and quickly found those worst fears realised. In a burst of blue magic, the illusion that Nightmare Moon had cast over Luna's eyes disappeared in an instant, and the glorious form of her Master and the darkly beautiful form of the Nightmare Goddess replaced him with a magical imitation of her Master's cock. Her face was one of wicked triumph.

[Derpibooru: 3031314]

Luna looked behind her, seeing the stage of her Master. The delight on Daybreaker's face was palatable, as was Celestia's horror and disappointment, Rose's perverted glee, and her Master's keen interest. "Wait, no-we-"

"So, Rose what do you think? Some might consider it cheating, but it's up to you."

"Um...." Rose's eyes darted between Nightmare Moon, Luna and Spike in a panic. Hating that she was forced to make this choice, hating the thought that she was put on the spot on this. Her mind wasn't sure what to declare, it certainly wasn't against the rules of the challenge but perhaps the spirit? Perhaps she should declare Nightmare Moon a cheater and give the win to Luna.

But... Nightmare Moon had looked hot as fuck dominating Luna like that. Turning the tables on the proud Slutprincess in an instant, and watching Luna becoming a whimpering whore. Imagine the entirety of Equestria under her heel, imagine how sexy such a tyrant would be...

"It's not cheating!" Rose's mouth blurted out before her brain could stop it. Much to the fury of Celestia and the despair of her sister, Rose was distracted by the wicked glee of Nightmare Moon, and the cackling erotic laughter of Daybreaker. "Nightmare Moon wins, we go on to the second challenge."

The dream world disappeared with a flourish of Nightmare Rarity's hand, and the whores returned to their natural dreams whilst the alicorns, Spike and Rose returned to the sex dungeon where an impatient Chrysalis and Twilight were waiting for them.

"The first round goes to the Nightmares."

Author's Note

I hope that isn't a cop-out to some people, but I needed the Nightmares to win at least one challenge.I hope people are enjoying Rose's character and her lust for all things evil, I'm glad I'm able to give her a more distinct identity from Sapphire here.

Ko-Fi's broken down, I can't crowdfund commissions any more. I'll still order some with my own money but it might be rarer unless I were to do AI art (which I know is controversial)

Any suggestions, feedback, and constructive criticism are welcome.
