When Spike filled Celestia’s body with his sperm, she started to glow, like the the light of the sun. Her body seemed to thrum with a newfound power, like the ethereal glow of an angel. Her wings flared out, now having a trace of light trail behind them and her eyes glowed like the sun. A collar and chain had formed around Celestia’s neck, a symbol of her new position.

It was for only a moment but afterwards, there was something different about Celestia, she radiated a new power around her. An influence that seemed harmless on Spike and Rarity, but affected Twilight and her guards. They had always idolised their Solar Monarch, but now they looked at her with the reverence of a goddess.

They broke apart from their orgy with Rarity to kneel before their Goddess, awe burning in their eyes. Twilight and the guards prostrated themselves before Celestia and chanted, “Princess Celestia, please direct us. Please sate your lurid lusts on us and use us for your pleasure. We’re just tools for your pleasure.”

Spike raised an eyebrow and Rarity looked scandalized as Twilight seemed to forget her Mistress. Celestia too seemed taken aback by how much power she now wielded.

“What did you do?” Spike asked. Celestia looked sheepish.

“Forgive me, Master,” she said, bowing her head in shame. “My new power allows me to influence all the ponies around me, imbuing them with a need to submit and serve. I did not mean for it to overshadow our Mistress.”

“That’s some power, can you turn it on and off?" Spike asked, his hands still idly playing with Celestia's pair of tits. Not rough enough to elicit any moans from the Goddess, but enough that he received soft smirks of pleasure.

"I can indeed Master, its power depends on the position of the sun. As it is noon, it's at its most powerful, but even so, I'm sure that with the Root of Magic, my power will pale in comparison to my Mistress." Celestia explained, smokey eyes daring Rarity to indulge in her new power.

"An excellent suggestion." Rarity purred, striding forward with the grace of a conquering queen, then leaning down and pressing her body against Twilight's back. Her flexible white arms wrapped around Twilight's own sizeable tits, as she turned on her power. There was no contest, the difference between Celestia's and Rarity's auras was the difference between an angel and an archangel. Whilst Twilight had looked at Celestia like a god, she looked at Rarity like she was the queen of gods.

"Please forgive me, Mistress, this useless slut forgot herself." she pleaded, bowing down at Rarity's foot and kissing it. Something that pleased Rarity's vanity greatly.

"Very well, my darling slut, but in exchange I'll expect you to do something for me." Rarity said, lifting Twilight's chin.

"Anything, Mistress. Your wish is my command." Twilight said, bowing her head in submission.

"Then follow me, I have a task for you." Rarity ordered, getting to her feet, Twilight following shortly behind her. Rarity then flashed Spike a smile. "I'll have a surprise for you when I come back. Have fun with the Princess, darling."

They walked out the door, leaving Spike with Celestia and the two guards before him. Spike was still molesting Celestia's boobs when the Solar diarch spoke again. "Perhaps you would like to see my other power now, Master?"

"Oh, I didn't realise that you had more than one. Sure, let us see it."

Smiling, Celestia turned to her guards. "Bring Ivory Stone back to here. Be certain to reveal nothing that she doesn't already know. She will be a demonstration."

The two guards bowed their heads, dressed, and left, leaving the dragon alone with the Solar Princess. "What do you need her for?"

"A demonstration." She said, coyly.

"A Princess using her subjects for demonstrations. Sounds terrible." Spike teased, only for Celestia to wave him off.

"Please, Master, what is the point of being a perverted Princess if you don’t use that power for anything?” Celestia suggested with a naughty grin. “Mmm, any other laws you wish for me to pass? Any naughty changes to make in Equestria you have in mind?”

“What about Luna and the council?” Spike pointed out. “You still have to deal with them.”

“You think in over one thousand years I haven’t considered that? I have plans to deal with my little sister and fuck that lovely ass of hers. As for the council? Well, you’ve already taken care of Blueblood, Fancy Pants, and Velvet, excellent work on that, by the way.”

“Thank you.” Spike said, before rewarding her by sticking his fingers into her pussy. Celestia’s face squirmed under the molestation of both her tits and pussy.

“Mmm…” she moaned, head rolling in ecstasy. “As for the others… I’ve taken care of most of them, but only three remain free of my control. My chief spy, Sweetie Drops, the climate director, Spitfire, and the new Captain of the Royal Guard, Tempest Shadow.”

“Wait, why is Tempest Shadow Captain of the Royal Guard?” Spike asked. In his old timeline Flash Magnus was the new Captain after Shining Armour had left.

“Well, I had to replace Gleaming Shield, Master. And I thought that Tempest had a lovely fuckable body and a fair skill for fighting. She lacks the appropriate attitude but we’ll fix that soon enough.” Celestia said proudly, before the doors opened and the guards brought Ivory Stone. The Young Mare was confused as to why she was there and then shocked seeing the naked Princess squirm under Spike’s molestation.

“Princess? I-I don’t understand, what is going on here?” Ivory stammered, head turning to the guards, to Celestia, to Spike, and briefly to his dick.

“Master, it seems an opportunity to demonstrate my second power has arrived,” Celestia said, detaching herself from her Master and radiating with her submissive aura again. Immediately, Ivory’s eyes widened like saucers as she threw herself to the floor, stripping out of her outfit as she did so in an act of submission.

“Forgive me for speaking out of turn Mistress, I was out of line. Please feel free to use me for your pleasure as atonement.” She begged, face blushing as she did so.

Celestia purred as she ran her hand through Ivory’s mane. “No need for anything so dramatic, my pet, just allow me to do this to you.”

Celestia pressed a finger upon Ivory’s chest and a light appeared where she had pressed, burning a symbol onto Ivory’s chest. It was akin to a gold coin, with the label ‘SPIKE’S’ like a piece of Spike’s horde. As Spike looked at the symbol, he instinctively knew that Ivory was now entirely his.

“Now Ivory,” Celestia purred into Ivory’s ear. “Look down on your chest and tell me what it means.”

Ivory looked down at her chest and her eyes widened. “It means I belong to Spike. It means he owns my mind, body, and soul.”

“Impressive power,” Spike said, his hand stroking his dick almost absently. "But I already have several ways to mind control ponies. What makes this power unique?”

“Well first of all I could be a bit more specific,” Celestia purred as she massaged Ivory’s shoulders. There was a flash of light and the symbol changed before his eyes, or at least the wording did. Flashing between ‘SPIKE’S TITS’, ‘SPIKE’S MIND’, and ‘SPIKE’S BODY’. “And that’s not all, Master, she could show this brand to the unaffiliated and they will simply accept your ownership over her. Useful, isn’t it?”

“Very. You said she was a sculptor? I want to own her skills.” Spike ordered Celestia, who smiled and changed the symbol to be labeled 'SPIKE'S SKILLS'.

"Ivory, your skills now belong to me. I decide exactly where your talent lies and what they’re to be used for. Now you are the best sculptor in the world, especially for erotic sculptures, and you’re going to make a sculpture of the moment I fucked Celestia in this throne room. Celestia, did you take a secret picture?”

Celestia smiled coyly, and, using her magic, made a camera appear, having been invisible before. She handed it over to Ivory. "Think you can work with this?"

"Yes, Princess. I'll get started immediately." Ivory said, rising to her feet and bowing to the Princess.

"If you need materials, then ask my guards, they will provide anything you request." Celestia said, shooing Ivory away and gazing hungrily at Spike's dick.

"And once you're done with that. Get in contact with me," Rarity said, standing at the door with Twilight by her side. The Princess holding a stack of papers in her arms and Rarity stood at the door, smiling coyly and flattering her eyelashes. "I would just love a similar sculpture, perhaps we might consider replacing the one at Manehatten with it."

"Ambitious, I see." Spike said, beckoning the two over to him as he sat on Celestia's throne. "What do you have there, Twilight?"

"It's a copy of Princess Celestia's law, and, as Mistress Rarity suggested, there's nothing in here suggesting a Princess would lose their power in government, so Rarity had me write up a contract for both us Princesses," Twilight explained, handing a copy of the contract to Celestia.

"What about you, Rarity?" Spike asked, raising an eyebrow.

"I'm waiting to get the unanimous support of all the Princesses, and besides I need some time to think over any terms for it. I assure you, darling they'll all be to your benefit."

Meanwhile, Celestia was reading the contract of her own enslavement, her coy smile growing wider with every word she read. "Well, Master, it seems that according to this contract, it will bind me to serve your every request, even if I disapprove. It will require me to anticipate your needs and fulfil them and love you more than the air I breathe. It seems I will surrender all my rights to you." Celestia clicked her pen. "Seem fair to me."

Rarity was beaming as she approached Spike. "So, only one Princess left Master. And only three council members to go, once they join our harem, we can drop the masquerade and you will rule Equestria openly. Looking forward to it?"

"I think you know the answer to that question."

Author's Note

So the vote is neck to neck. That's a blatant lie, Luna is going to win. This is more one-sided than the Rarity vote, and I might as well close the vote now. Though I will keep it open nonetheless. Suggestions for Luna are welcome though I do have several ideas already. Thank you for all the suggestions for Celestia's new powers as the Princess of Servitude, I hope everyone enjoyed these chapters.

Also, I decided to clarify who was left on the council to corrupt. So Tempest Shadow, Bon Bon and Spitfire since taking control of the Wonderbolts, Royal Guard and S.M.I.L.E. makes the most sense to me. Once they and Luna are taken I'll start voting on the next setting.
