Nightmare Moon landed in front of the Everfree forest, unable to simply fly to the castle as the skies over the Everfree were wild and the thick tree cover made rough landings impossible. Though as she landed, Nightmare Moon felt a wave of pleasure washing over her, the motion bringing her cock deeper into her bound slave’s mouth attached below, before she went inside the mystical forest.

As she walked the path towards the old castle, cock firmly sheathed inside Sapphire’s mouth, she pondered the threats she could potentially see during her trek. Mostly timberwolves, something she could easily deal with, though there had been rumours of a pony with hooves made of bark prowling, looking for any pony getting lost in this woodland to snatch.

Despite the Everfree’s reputation, her trek was rather peaceful, looking at the ground in front of her, she noticed why. Bundles of exploded and burnt wood were scattered across different parts of the path. Daybreaker had cleared the local disruptive timberwolf pack, she only had to blast a single timberwolf that tried pouncing on her in vain, and there she was, the old castle.

Entering the decrepit building, she looked towards their ancient thrones and saw the pony she was supposed to meet. Sitting on her old throne while donning a smug yet sultry look, she gazed at Nightmare Moon, causing the Lunar Empress to give but a small hint of red on her countenance, finding the Solar Empress’ pose quite attractive.

“I see someone’s taken inspiration from me,” Daybreaker said, her voice giving a sultry energy while her sight centered around the bound alicorn below Nightmare.

Focused on removing the ropes attaching Sapphire to her and letting her slave drop, Nightmare replied. “I have to admit, it was a good idea, now what did you wan-mmph!”

Immediately as she turned her head back towards Daybreaker, she found her mouth getting locked with the Solar Empress’, kissing her deeply. What used to be a small shade of red on Nightmare’s face now became much redder and her cock throbbed with excitement.

Daybreaker pulled back. “That is what I wanted to say~”

“Wh-Wh-What!?” Nightmare Moon was utterly confused, unable to comprehend such a move by her opponent. “E-Explain!”

“I did something unique to our little slave there before giving her to you, I put a scrying spell on her to see if you would not betray me, by the way, if you did we wouldn’t have met here.”

“But that doesn’t explain what you just did!”

“The spell gave me access to Sapphire’s body, and with her hearing I heard you calling out to me as you were fucking your slave, something about our love destroying our foes,” Daybreaker said with an incredibly smug look.

“A-Ah-I-I s-see,” Nightmare was stunned by Daybreaker’s words. She couldn’t believe she hadn’t checked her gift for any magical effects! But then again, it was something Daybreaker never did. “But what of our conflict? You never gave me the chance to rule alongside you!”

“I was getting pressured by the nobility to keep the status quo, don’t steer the wheel too hard or risk plummeting Equestria into chaos, they said. Idiots,” Daybreaker added, “but they are gone. I control my Empire now. I decide what I want to do and my followers get it done no matter what, no stupid bureaucracy here.”

“And with all these victories against the Harmonists, and our trade going correctly along with the fact that I now know you share this love with me. I want to bury the hatchet. Besides, you had a good point. Together we could rule all of Equestria, take the last bastion of Canterlot and even expand further! Why stop at Equestria when we could rule all of Zebrica or even the distant Kirins! All under our might!”

“So you love me? My new self?” Nightmare asked, worried that her Sister only loved the old, long-gone version of her, supplanting the amazing speech Daybreaker had just said.

“The old me loved the old you but was too weak to make any advances. I am not weak and when I want to say something, I say what I want to say. I love the new you. Powerful, cunning and fucking hot.”

“I am glad to share this sentiment with you,” Nightmare Moon said with a devious smile, giving Daybreaker’s physique a closer look, especially that cock of hers before going in to kiss the Solar Empress. Both of them embracing lust and love as they both kissed for a solid 2 minutes, both pulling out at the same time after.

"Though I am surprised to find common ground with you this fast, sister," Nightmare continued, "It feels like not too long ago I wanted to-"

"Destroy me? Banish me? Imprison me?" Daybreaker interrupted, "I felt completely the same way, but this is too big of an opportunity to pass and until recently I kept pummeling my feelings towards you thinking they would vanish,” she paused, that last part was perhaps the only foolish thing she had ever done, but there was no way she would have known.

“I think we just needed to gain back trust, and an annoying alicorn gave us that plenty, along with a common goal to deal with. Speaking of…"

“How do we manage her?” Daybreaker asked, just now noticing that Sapphire was also there, looking like she had seen pure joy as a massive smile ran across her face, like she saw her biggest wish get fulfilled.

“Oh,” Nightmare Moon had also forgotten about her slave. “You can have her for now, as agreed, but when we join together. We should keep her as our personal fuck toy and servant. After all, she was the one who managed to make us build trust with each other, she is a symbol of our union.”

“I couldn’t agree more, Nightmare,” Daybreaker laughed, victory in her tone, joined by Nightmare Moon doing the same, before she spoke.

“Now, let’s see how we can merge our empires together, sister.”

Months had passed, the rift had been used for constant back and forths between the empresses, talking about their plans, goals, and how they had fucked their slave that day.

With Nightmare’s wit and knowledge of subversion and Daybreaker’s unbound charisma combined, they had managed to redirect the war onto something else, and declared the formation of a new, united empire, to combat the bigger threats to Equestria. The Changelings, the last Harmonists and all other faraway lands had been the real cause of this rift, or so the Empresses told. The blame for the war had been shifted to them and the people agreed, following their Goddesses’ every word.

What could not be done with one army was easily done with two. Canterlot had quickly fallen, overpowered by the combined might of the Solar and Lunar Empire, and the two empresses changed their capital to the reconquered jewel of Equestria.

In the throne room, both of them rutted their slave, as Nightmare Moon took Sapphire’s mouth, while Daybreaker enjoyed her marehood, both ramming into her with reckless abandon. That moment was significant for them, as held in both of their magic was a piece of parchment officializing the creation of a brand new Empire. It only needed two signatures.

For now though, they were celebrating, shoving all their might into their pathetic fallen ‘princess’, and every couple of minutes, Sapphire climaxed from the sheer bliss, from the sheer force pounding her from both ends. She loved serving her Empresses, to be used by them, it was her purpose.

They came inside Sapphire so many times the floor had become a complete mess of their fuck toy’s mare juices, and of their copious amount of cum. But they did not care, all were stuck in this moment of carnal pleasure, of pure bliss, as both rulers kissed deeply while pounding their slave, cementing their union by filling Sapphire as much as possible.

Sapphire moaned with complete lust and bliss in her mind. Her loud sounds of pleasure, partially muffled by Nightmare’s cock constantly thrusting into her mouth. She quivered from the intense bliss, barely able to stand as all her strength had been sapped away from the unending rutting.

She sported a new collar, one with a combined livery of her Empresses’ colours and with both of their sigils, their cutie marks, sun and moon.

After countless, seemingly infinite hours, they had finally begun to out of stamina, the floor below them was almost like a lake, but it was still beyond their worries. They had power. They could simply order somepony to clean without them asking any questions, lest they face their wrath.

They revelled in the intense bliss that they went through, in the immense pleasure given from thoroughly breeding their slave, a moment for the ages.

Yet they were not done, they had one last thing to do, to help complete their permanent alliance along with the document. Nightmare and Daybreaker exchanged looks, subtly signaling their intent to one another, both finishing their trade with a devilish smile.

Sapphire was given a very brief respite as both rulers pulled out, causing a significant amount of cum to leak out of her overstuffed marehood and for her to drool Nightmare's plentiful cum, but those holes were soon plugged once more as the two Empresses switched places. Once again, Sapphire felt a massive wave of pleasure overcoming her as Nightmare's cock pushed through her walls and heaping amounts of cum, stretching her more, and Daybreaker filled her empty, needy mouth.

They immediately pummelled her with all the force and energy they had left, the small pause previously given had greatly amplified the feeling of pure pleasure Sapphire felt as they fucked her with reckless abandon, her moaning growing to intense proportions even while blocked by the unending throat fucking she was under.

Sapphire's muffled moaning was joined by the Goddesses doing the same, muffling their own moans under a deep kiss they went back to sharing. No amount of pleasure was comparable to what they were going through. Images going through their mind of blissful unity, infinite power and most of all, shared love.

Their final climax had arrived, forewarned by the intense sounds of bliss they were making whilst kissing, as Daybreaker filled her throat with her warm seed, while Nightmare stuffed her marehood with her own copious amount of cum, joining and mixing with her sister's already plentiful cum. They all felt like they had been sent on a new plane of existence, one of pure unrivalled joy and pleasure, as Sapphire's body quivered and shook from the insane amount of lust it was under, taken by its own intense and incredibly blissful orgasm.

With both their glorious future progeny unified inside their slave, they signed the document, their union twice affirmed, twice solidified, and thus a new empire was forged. The Moonlit Sun Empire.

Sapphire’s blade was up on the wall in between their thrones, a trophy of her descent. Engraved on the blade’s stand, it read:
‘With her fall, we found unity’
