In a large room in an expansive castle made of crystal a swirling magical vortex opened once more, depositing a somber Princess Twilight to the floor. Twilight’s return home was bittersweet at best. She’d both lost and won. Seen a friend find their destiny and lost her beloved mentor and in some ways, mother.

Yes, the Celestia of Sunfall wasn’t Twilight’s Celestia, but she looked and sounded like the mare who had given a young pony everything she had ever wanted. As a youth Twilight had been like a desert, thirsty for knowledge, and Celestia had been the river bringing life to that arid wasteland. Celestia had given Twilight power and purpose, knowledge and guidance. Seeing the broken alicorn die had been like feeling a piece of her own heart die.

“Hello there,” said a gentle, rich voice.

Twilight turned toward the door, and there she was. Eyes of infinite knowledge set over a mouth that had laughed and spokne and taught, over hours and hours of Twilight's formative years, in a body of perfect white fur over smooth muscles that carried surprising strength and resilience. It was Celestia, alive and whole, and all together exactly the mare Twilight needed to see at that moment.

“Princess,” Twilight half-cried, half-choked out, moving forward and embracing the taller alicorn. “Oh Light, I’ve missed you.”

“I missed you too,” was all Celestia said in response, returning the embrace with both hooves and wings.

Twilight was in a snug, warm heaven. Ivory softness surrounded her, holding her next to the beating heart that had guided Equestria for a thousand years, and the lives of Twilight and her friends as well. Strong but gentle hooves stroked and comforted the young alicorn, much as they had back when they were teacher and student.

“Still wearing my collar, I see,” Celestia noted, lifting Twilight’s chin so she could look into the younger pony’s violet eyes. “It’s a good look on you.”

“I—” was all Twilight managed to get out before Celestia covered Twilight's mouth with her own.

It was a good kiss, a deep kiss. It started slow and built into something worthy of two princesses of Equestria. Twilight hadn’t expected to be kissed, but willingly gave way to the commanding sea-shape in her maw as it touched and stroked into being a wave of warm desire within her that threatened to grow into an ocean of pleasure.

Twilight tried to respond in kind, tried to demonstrate some of the many things she had learned over the past few months, but the prodigious power and skill of Celestia’s slippery, skilful, hippogriff-like tongue overwhelmed her with a tactile, tea-flavoured dominance that demanded Twilight’s oral obedience.

The young alicorn felt herself sinking deeper into the strong embrace that bound her as tightly as any chains, while the rising ocean of joyous rapture threatened to swamp her and her mind with pleasures that had been created over generations of life.

Which is when, at long last, Twilight’s ever working intellect managed to pierce the fog that the ivory alicorn had spun through her mind with that glorious osculation.

“Wait,” Twilight begged, pulling her head back with a significant effort of will. “You said ‘my collar’. This isn’t your collar, this is the one Flim and Flam put on me back in the…”

“Quite true, my little pony,” Celestia replied, and it was at that moment that Twilight saw it. Dominating strength, combined with the force of will and a complete lack of empathy that enabled a once loving ruler to become a tyrant who was more than willing to enslave each and every one of her citizens in the name of safety.

That it also satisfied a depravity fuelled need for possession and control was besides the point.

“How long?” Twilight asked, aware that at any moment the caressing wings gliding along her sides could clamp down with a ferocious strength.

“Not long,” Celestia said, somewhat enigmatically, as she dipped her muzzle down to nuzzle the spot where Twilight's neck joined the rest of her body, drawing an involuntary moan from Twilight; as teeth delicately scraped along her skin and setting nerves all over her body alight with joyful pinpricks.

“Wha… what are you going to do with me?” Twilight managed to pant out, desire growing in spite of the deadly danger she was in. No matter what else this Celestia was, she was also insanely well versed in how to build an inferno of desire in a pony.

“Well, that depends on how interesting you plan on making things for me,” Celestia stated, a smile of anticipation on her face.

“I’m not alone here,” was Twilight’s response, doing her best to ignore the tips of feathers that were tracing languid circles around her dock. “All I have to do is yell and this room will be swarming with an army.”

“Already mine,” said Celestia, and there was a sort of bubbling joy in that warm voice now. “Your castle is mine, your guards are mine, and now once again, you are mine.”

“Then I’ll fight you,” declared Twilight, pulling back from Celestia and almost surprised that she succeeded.

“Precious little possession. I’m going to have such fun breaking you to my will,” Celestia laughed. “It’s already too late for you to try to stop me.”

Twilight stood there a moment, bewildered and confused, before realizing that the tingling and mild tickling sensations she had been feeling from this Celestia’s wings and arousing touches hadn’t abated at all. In fact, they were spreading and moving over her back and down her sides.

Twilight twisted her head around to look at her back, and as she had anticipated she saw the spreading glossy blackness of a latex symbiote flowing over her contours and down along the sides of her barrel. The feared, dreaded, and Light help her, loved construct was overwhelming her violet fur in darkness, capturing it effortlessly in its embrace. Capturing her just as effortlessly.

“You may have me, you may even have my castle and my guard, but that doesn’t mean that a single one of us is going to give up and surrender to you,” Twilight stated, trying not to gasp as the slick firmness finished looping under her and tightened into a corset-like structure.

“I love your spirit. You’ll do well as the one assigned to draw my chariot,” Celestia leaned close and that motherly voice turned into something darker as she continued with, “wouldn’t you like that? Bound and harnessed. My helpless little draught mare pulling me along, even as the suit drives you onward harder than any whip could.”

“Guards!” Twilight yelled, as the suit enveloped her nethers, increasing its hold on her but not penetrating her. No, not yet. Twilight knew that was yet to come.

“I told you, your castle is mine, and your guards are mine,” Celestia reminded her, a smiling face over eyes that gleamed with the anticipation of cruel, erotic torments. “You want this, don’t you? Ever since you managed to escape from Flim and Flam’s keeping, you’ve missed this, haven’t you?”

“Missed what?” Twilight demanded, feeling her wings being folded and furled against her will as the suit overrode her nerve impulses with its own. “Missed being enslaved? Missed being degraded and violated at every single opportunity?”

“Missed not having to worry about things. Not having to set priorities, or worry about this pony, or that town. Missed not having to control anything, because Control was always there for you,” Celestia reasoned, watching with satisfaction as Twilight’s wings were fully captured and sealed away in pockets on either side of the suit.

“Yeah, that pesky free will was always getting in the way,” Twilight snarked, barely holding back a shudder as the suit flowed down her legs and enveloped the sensitive frogs of her hooves.

“I saw the recordings of your sessions, you know, 614,” Celestia commented, reaching out with a line of golden magic to snare Twilight’s collar in a leash of power. “You enjoyed every moment of your sessions with Control, admit it.”

“Restarting,” said the collar, in its neutral voice. “Suit 614 accepting updates.”

“So, my choices are surrender or die?” Twilight asked, all too aware that the all-encompassing suit would envelop her head and smother her by default.

“You think I would deprive myself of the fun I'm going to have with you by letting you die? You don't have any choices anymore, least of all choosing to die. You're going to be my personal plaything, for a very long time, perhaps forever,” Celestia told her, and Twilight could see the anticipatory joy in the alicorn’s eyes. “Suit 614, recognize Control Prime.”

“Recognized,” replied the collar. “Initial configuration for 614?”

“Prisoner configuration,” Celestia ordered, and Twilight felt the suit crawl the last inch up her chest to mate with the controlling collar. “Full hobbles, full magic lockdown, enable bridle and standard blinders, muzzle on standby permitting normal volume. Disregard commands from any other Control. This pony is mine, and mine alone.”

“Password?” demanded the collar, as Twilight felt the extra bindings come to life around her body.

“Daybreaker,” Celestia replied, with a vicious edge that made Twilight’s blood run cold.

“So now what?” Twilight asked, feeling her skin come alive with tiny pricks and tingles as the suit began its process of fully bonding with her.

“I expect a period of your trying to resist me, which I'm going to enjoy greatly. However, we both know that in the end you will do anything I want you to, and do it gladly,” Celestia informed her, adding, “but in the meantime, I have to make sure your retraining isn’t interfered with by my counterpart.”

“My Celestia is twice the mare you are,” growled the bound alicorn. “Once she discovers that you’re here, her and Luna will come down on you like nothing you’ve ever seen.”

“Oh yes, that’s right,” Celestia noted, “You let your Luna run around like some sort of lunar loose cannon. Another thing I’m going to have to fix, once I finish taking over your world, that is.”

It was more than Twilight could stand, and with a growl of fury she leapt at the intruding solar alicorn. Or at least, that’s what she intended to do. Instead, the band connecting her fore and rear hobbles snapped tight, robbing her leap of nearly all of its speed and power. Twilight collapsed in an ignominious heap at Celestia’s hooves.

“One,” noted Celestia, following up the pronouncement with a hard smack to Twilight’s rear. The magitech latex symbiote did nothing to dampen the sting of that initial strike, nor the spreading warmth from the point of impact. “Every time you disobey me, the number of spanks will go up, and it will do so until you beg me to fuck your brains out.”

“Eat shit and die,” stated Twilight, stealing a line she’d heard Dashiel use more than once.

“There’s that fire I’m going to enjoy playing with,” crooned the controlling alicorn, dragging Twilight up to her hooves with a choking grip on her collar. “But for now, I need to deal with your Celestia. I want you to write her a letter asking her to come here right away. Add in that the matter is urgent and private, so please don’t bring any extra guards. Oh, and she should also bring Control, I mean Alyss, with her.”

“Like hell I will,” Twilight spat back.

“And that’s two,” Celestia noted, punctuating the comment with a blast to each butt cheek, setting them both aflame. “And while I don’t need any pony to carry out my will, I’ve learned it helps to come prepared.”

“Wh-What are you talking about,” Twilight said, biting her lip to keep from groaning out at what just three strikes in total from the other Celestia had done to her.

“Come out here, eighty-two sixty-three,” commanded Celestia, to a dark corner of the room.

To Twilight’s complete shock and horror, out stepped a unicorn version… of herself! The mare was lean, sleek and possessed a glossy secondary tail that Twilight knew was buried deep inside the other pony’s rear passage. As the other version of her came closer, Twilight could see nothing of curiosity, self-will or even self-preservation in the mare’s eyes.

“8263 reporting,” stated the unicorn, prostrating herself at Celestia’s hooves. “I belong to the Eternal Day, living or dying as she who controls both my life and body commands. What is your will?”

“8263,” began Celestia, “take a letter…”

Looks like somepony followed Twilight home! This could be very interesting.

Also, my profound apologies for the shortness of this chapter. I got my second dose of the Pfizer covid vaccine just as I was about to move on from the first part of the chapter and my immune system went:

Let's just say my side effects were bad and they wiped out nearly all my writing time. I am on the mend and the side effects are now mostly minor. However, the best I was able to give you was this short introduction to the next section. I WILL be adding to it.
