Nightmare Moon and Daybreaker stood before the other. The rules were already set for what they would do. Both were too prideful to abdicate power over Equestria to the other, so now came the contest. The goal was to break the other one through humiliating them so badly that they concede in not being worthy of ruling.
Both hadn’t bothered getting dressed, which pissed both of them off. While their feeble, good counterparts had more differences in physiology, they were almost crafted from the same mold. Tits twice as big as their head, an ass that was tight with hips that gave them an overall hourglass body, and perfectly toned bodies.
The main difference was how Nightmare had normal eyes and her mane of stars, while Daybreaker kept her black and yellow eyes while her mane of fire wrapped around her in a show of dignity so she wasn’t merely bare. Besides, she expected her stupid sister to use her first command to make her reveal herself, which would give her an edge.
Instead, Nightmare Moon, who had won the chess game before this, snapped her fingers, her horn glowing bright as she did so. It washed the room with black energy, blinding the two of them temporarily. Daybreaker expected the worst, which were mostly her own plans, and…
Nothing. Nightmare and her were untouched as the night bringer simply stated, “Your turn, sister.”
Daybreaker snarled at the calm, even tone. Luna was the reactionary of the two pure forms, while Daybreaker was about ready to go into full combat in order to show her dominance. Fortunately, with how composed Nightmare was being, she bet she could break her easily. “I will see if you can be so confident when your insides are turned to mush.”
Like her sister, Daybreaker added the flare of snapping, but she didn’t bother blinding them. Instead, her magic brought Cerberus through a fiery portal. It wasn’t the only spell she had cast, as Nightmare quickly realized as she felt a Want Me, Need Me spell put on her. No, not on her...
She swallowed hard as the large, three headed animal pounced at her. Nightmare obeyed their rules, which was to endure at least one round of whatever task they were given, by getting onto her stomach, She didn’t want to get torn in twine after all as the beast tried to fill its lust.
And lust it felt. Nightmare could see its twin cocks, both the size of her, and acted fast. Bottomless nethers was going to protect her organs, and those were far more vital than anything else as the beast lunged for her.
Cerberus was surprisingly gifted at the job of insertion, as the hell beast had been trained for any sort of punishment, and Nightmare screamed silently as her pussy and ass were forced open wide. They were simply too big for any mare, and tears quickly sprang to the tyrant’s eyes.
Fortunately, Daybreaker had made a mistake. While trained in this, Cerberus had never had to do this to somepony, and its eyes widened as it tasted demoness pussy.
Fortunately, to satisfy Daybreaker, while he didn’t continue to rip her sister apart, the beast did manage to pull out before cumming. His cum came thick and in pools, quickly drowning Nightmare Moon in the white, sticky substance before she managed to teleport the hell beast away.
Daybreaker chuckled as her sister slowly got up. The black mare was now as white as her, and wasn’t allowed to clean herself up, as per the rules that they had to keep whatever harm or alterations were done to them between rounds. At least, she couldn’t clean herself magically, as the night bringer was still able to wipe clumps off of her, though her coat would be a mess for weeks. “Well, sister, are you regretting failing your first spell?”
Nightmare glared at Daybreaker, before taking a deep breath in, the smell of Cerberus spunk filling her lungs. She doubted she would be able to get rid of it for a month, if that, but it would be worth it so long as she won. With one hand she wiped cum off of her horn, while with the other she calmed herself by placing it atop her heavy chest.
Then, without a command or word, her horn flared to life, blasting a vine of black energy into Daybreaker and sending her across the room.
But, like last time, nothing actually happened. The blow hadn’t even hurt Daybreaker, as it more surprised her.
“Your turn sister.”
‘Oh, like, this isn’t cool. I am way cooler than her, and I’ll show the bitch that.’ Daybreaker sprang back to her feet, before her eyes flared with the magic she brought forth. A simple summon wouldn’t do this time. No, she would need more to break her sister.
And then, Nightmare Moon disappeared for a moment, much to the guards in the room’s surprise. However, it was also only an instant later that she was back.
Nightmare breathed in deeply as she shook. She had been sent to the chaos plane for only a second, but in that time, the results were obvious. She shook from the horrors, her nose now clogged with a smell far more putrid than simple cum, while black sap dripped from her body, burning it with desire and pain, because it was molten hot.
Nightmare slowly stood up. Her coat was marred by burns, leaving a softer blue to show through that was her skin. At least, where she hadn’t been burned to a charred black, which was the entirety of her chest.
“How were the nether tentacles? Aren’t they just, like, the worst?”
Nightmare seethed with anger, before shaking her head. She was at least no longer coated in semen, even if the sap hurt a hundred times more. She had to stay focused on her goal. And, as such, Nightmare let her horn flare to life again, and two small rings came to being above Daybreaker.
Daybreaker blinked as the small rings came to her front, before they clamped onto the base of her chest. She immediately screamed from the pain, because despite not breaking the skin, the spinning rings that now stayed on her chest felt like they were trying to saw them off.
What they were actually doing was entirely the opposite. Despite being magical clamps, they also pumped something into her chest. With each rotation, another millimeter was added to chest, and they were forced to sag under their own weight. Her body was meant to be perfect, and this was messing it up!
After going up a cupsize, and feeling filled with something, it was more than Daybreaker was willing to deal with and slammed her own magic into the rings. When released, her breasts were allowed to sway freely, and she could see some sort of green liquid flow from her nipples. In fact, she could feel some sort of tickling and bubbling in her breasts. While they tickled her, which she quite liked, it felt entirely unnatural to her. “What did you do to me you cunt!?”
Nightmare frowned for a moment, before shrugging. “I made it so that you now lactate Mountain Dew, in honor of my counterpart. The breasts expansion merely came with it. Also, you cheated.”
“Oh, like I give a single fuck about your little rules. I am, like, the best, sexy bitch here, and I bet fifty cocks would agree with me.”
Nightmare merely smiled as Daybreaker licked her lips, and how the sun tyrant didn’t notice that her mane no longer covered herself.
Daybreaker’s eyes then widened as she came up with an idea, though she couldn’t remember her old plans now, and snapped. In an instant, the guards in the room’s armor was removed from them, their now enhanced, throbbing cocks hanging erect in the air. “Guards, you may do as you please with my sister.”
The guards naturally hesitated, because while they were aroused, now made painfully so by Daybreaker’s spell, they had been brainwashed to only serve and revere these two. Their minds were made up as Nightmare’s horn came to life and they felt the pain in their loins be eased. “Really sister, why must you torture those we’ve already done enough to?”
Daybreaker visibly shook as the men didn’t do as she told them to. “What are you fools doing? You may do whatever you please with her. Anal, nipple, anywhere to fuck! Do I have to offer you to do it to me after or something?”
“Why would you allow them to do that?”
Daybreaker was completely losing it now as she screamed, “Because, like, you’ll hate it, while I’ll love it. Now, get on your-”
“No. I’m done playing now.” Nightmare Moon extended a hand, and an orb materialized in it. Above her screens popped up, showing the two of them from multiple angles. “My first spell is one you wouldn’t know. Not with your pomp, and not with your age. You haven’t been waiting for this as long as me. Needed this as long as me, and so you do not know what ruling Equestria will take.”
“Thus, my first spell was to prepare the strongest spell in the royal arsenal.”
“Will of the Ponies.”
Daybreaker blinked. A small part of her was screaming that she had to stop this, but mostly she thought this was soooooo boring. She should be sucking down some cocks, not listening to her sister prattle on. Did she, like, not know how to humiliate a mare? In fact, she probably was the one who made her so much more willing for all of this, which would easily make her lose.
“What this spell does is that it poses a question to every citizen of Equestria. Mine is which one of us you wish to rule, and which to serve as a proper whore like this contest was always meant to cause. I pose this now!”
Daybreaker barely registered that the orb had the two options on it now, and she definitely didn’t realize the votes were coming in, not while she thought, ‘Wow, sucking every cock in Equestria sounds so g-’
Daybreaker’s non-corrupted mind came to the front for one second, before a majority was found, and the whore was teleported, with every single change to her that would be needed to make her a good whore.
And the second the screens were gone, Nightmare Moon collapsed, her guards already coming to her to get the qualified ruler to the infirmary.
For silly games are no way to decide who should rule, even if you’re the one who first suggested it.
