Tirek approaches his final stop in Tartarus. Before him is a metal golden shape pentagon with the same no-knob door on the front of it. A cartoon picture of a sun hung above the door symbolizing its use.

Tirek hesitates not exactly sure how to go about this. Unlike Cadence or Luna. The Sun Princess was the actual ruler of a kingdom for thousands upon thousands of years. From the humble beginning of Equestria to the upcoming end of it, she has been overseeing the growth and developments it went through, gaining invaluable experience in the process. She was the cunning chess master pretending to be a pawn. One of the many reasons why Tirek despised her.

His hand pressed itself against the door watching it flash white before opening up. He trot inside to see Celestia in all her naked glory.

Celestia has a solid G-cup rack with a complmenting hourglass figure. Her wide birthing hips and plump ass, double the size of Cadence's, made her more appealing than any other alicorn. However, all Tirek felt was disgust and hatred toward her. She was in a squatting position only held in place by a set of ropes leading up to the ceiling. Her arms were strapped into an enchanted arm binder that was reinforced with thin fibers of steel. Her legs were tied separately and spread apart to fully expose her naked cunt. A rope was tied to each kneecap was secured tightly to the opposite walls to prevent Celestia from closing her thighs. And her wings were firmly tied in above the armbinder restraints.

The body was tightly bound highlighting her tits, leaving her pussy untouched. Celestia seem to be squirming in place, if ever so slightly now, and face flustered. Then Tirek remembered the parting gift he placed in her lovely unexplored ass. A decently sized vibrating dildo was buzzing away in her ass for the past several hours now since he captured the original three alicorns.

A pleasant smile graced his lips coming out of the shadows of the room. Celestia immediately recognized the centaur. "T-Tirek..... Tirek, I know this seems... ngh, out of the blue, but I can give you something more than you could ever dream of, if you listen to my proposition."

He had to think twice on that offer. He knew Celestia was clever at twisting words to her advantage, so he wasn't certain if she would try to bargain her freedom for something. But he had to admit, Tirek was a bit curious of what offer she was suggesting. "And what offer would make it worth my wild?"

She look to have figuratively swallowed her pride seeing she was in no position to properly lay out terms. "I will offer my body..... and a baby, if you wish, in exchange for my country, sister, and Cadence's freedom."

This was just too perfect for Tirek. She had no idea what happened during her time in captivity. It would have been a perfectly reasonable offer to give when someone could just conquer an almighty powerful ruler of the sun. This offer might have worked..... if he came to Celestia first. But he knew her well enough to not intending to make another foolish mistake again. He did like the idea of how she is basically offering to be his willing sex slave... If only she couldn't manipulate people...

"An interesting proposal, Celestia. I never knew you would sell yourself so willingly for everything you care about, but you see.... I already have everything you just offered and more." Celestia seem to not understand what Tirek was suggesting, showing her confusion. "Let me rephrase that: 'I have already broken your precious Luna and made Cadence into my child bearer'. Oh, and your 'faithful student' is already under my control along with the rest of Equestria," That last claim is a minor lie, but what she doesn't know won't kill her. "Unfortunately, I couldn't allow my enemies to live, so Discord and Twilight's friends are gone forever."

Celestia, in all of her years of longevity, has never felt so much hatred for one person. It was so mind numbing that all room for talk had long past now. She wanted blood. Her stoic mask instantly broke apart, teeth grit together, eyes lit up in a fit of rage. "I hope you're happy that you have started the end of your life with your own life choices. I promise I'll make sure to put you out of your misery myself if I have to."

Normally, a death glare and threats like that would make anyone, even a centaur with all the magic in Equestria fear for his safety. But Tirek knew she had no power in his domain. Not to mention the lovely predicament she was currently in did no favors to enhance the effectiveness of her words. Tirek grinned to himself before an idea quickly came to mind.

Tirek smirk before gently gliding his hand over Celestia's left cheek. The white alicorn for a moment pondered what he planned to do. He instantly use the same hand to grip her flowing hair making her head jerk up closer towards Tirek's piercing yellow eyes. Her conviction faltered just a tiny bit.

"It doesn't matter what pretend threats you may have, sun bitch. Because you will cause me no more suffering ever again. As a matter of fact, I have came to see you to deliver your long awaited punishment."

"Punishment?"

"Precisely, slut."

Her anger flared. "I am not a slut, Tirek! Call me-"

His grip tightened making Celestia wince in pain. "I didn't ask for your opinion. I can and will call you whatever I want, whenever I want. Am I clear, sun slut?" Tirek growled back.

Celestia almost immediately tensed up in fear at the intensity of his glare. "I-I understand..."

With that issue addressed, Tirek let go of Celestia's mane. He then trot off making the white alicorn dread the possibilities of his next action. Tirek opened a chest fill with interesting torture devices. But he won't needing anything harsh to break her.

He searched the chest before finding his prize. He held a dildo that seemed to be an almost perfect mold of his monstrous cock. The only key difference to this model is the shaft of the dildo was double the thickness than his own dick.

Tirek smiled before trotting back up to the Sun Princess. He displayed the dildo to Celestia watching as her pupils shrank in realization. "I hope your ready to accept this length easily. Especially since you are a fresh bitch."

The centaur didn't wait positioning the dildo to slight push open her vaginal lips-

"W-Wait, please. I'm a virgin. It-"

Tirek firmly pushed the dildo all the way inside her to the hilt. Her head reeled back, a scream tore from her lungs. Tears forming at the edges of her eyes. Tirek silently watched a trickle of blood escape her stuffed enterence.

The centaur was a bit surprised at her strikingly true revelation, but saw the potential this avenue manifest. Luna's too broken to be an effective slut. Cadence will be his breeding tool, so training her would be close to useless for her purpose in life. Celestia however...

Celestia's body shook under the sharp pain she felt getting violated. Tirek chuckled amused by the turn of events. "Wow, who could have imagined a self-absorbed cunt like you were a virgin? Let me guess, you had to be pure due being of royal birth. And to think that virginity was taken by a dildo of the same mold of my cock? I guess that makes me officially the true King of Equestria." The horror and dread of what she offered before finally hit home in her mind. "But you and your sister aren't even close to worthy of my 'royal' seed. Not by a long shot. Which is why I'm spending my time in teaching you humility and submission to the new King of Equestria. His magic flared to life sending the giant dildo buzzing twice the speed of the anal vibrator.

Her back arched trying to hold back the supressed moan. Tirek watched her helpless display of stimulation. She focused all her energy on holding back the orgasm. To her surprise, she felt her body betray her; the heat rising to a boiling point of no return. Before she could push herself over the edge, however, the device began to rapidly cool off, leaving frustrated and wanting more. Then after a half hour later, the vibrating picked back up again. This process continued for several hours making Celestia more and more desperate to cum. Time flew by faster for Celestia has her rational thoughts were being overwhelmed by primal instinct.

She wailed in sexual frustration feeling the device cool off again for the twelfth time. Her legs shook violently. Her voice caught in a shaken battered breath. Once the device picked back up she tried lightly bucking the air for some sort of release. All her previous dignity lost to her instinctual pulses. "Please, please. I need to cum. Please, let me cum. I'll do anything! I need to release, now!"

Tirek meanwhile was lazily reading some sort of discarded PlayBoy magazines. "You don't seem to be in a hurry to cum." He idoly commented.

A spike of anger rose in Celestia, but was immediately trampled by the out-of-reach bliss of cumming. She's never been treated like this her whole life. And to think a upstart villain got lucky and was able to effortlessly make a fool out of her was unthinkable. She was the ruler if the sun. A goddess that could burn whatever she wanted without a second thought. Yet she and all the other Alicorns, were easily conquered by a barely known centaur with magic absorption capabilities. And here she is begging to cum right in front of him, yet he is just casually reading a porn magazine not even slightly aroused!

She would have guessed most stallions would have let her cum after this display of humiliation and degradation. What more does he want from her? Her eyes started roll a bit into her head. Then something deep with in her decide to voice itself.

"PLEASE, MY LORD. Let this unworthy cunt cum her brains out for you. I've been a greedy slut which deserves all your punishment for misbehaving! Please have mercy on me, and let me cum, my lord!"

Tirek actually peeked over the porn magazines hiding, inwardly pleased. "What a well behaved slut you are starting to become. I'll allow you to come once for your good behavior."

He temporarily released the denial spell watching the result. Celestia trembled in the binds the orgasm rocking her very core in bliss. It was a heavenly feeling to behold to the once mighty sun princess. Her tounge lulled out of her mouth uselessly, girl cum fluids splattering all over the floor.

Tirek then quickly reapplied the denial spell watching the horror seep into Celestia's face. Now the horror stemming from the rapid cooling effect of the toy, or the realization she prostrate and degrade herself to her enemy is something Tirek wasn't entirely sure which one.

The dildo vibration was lowered to keep her mind focused while Tirek trot back into the darkness to find the suitable equipment for the upcoming punishment. The centaur quickly found the display of whips on his magical manifestation tool rack. He glanced at the different types eventually settling on the single lash whip. He placed the whip out of sight for now before trotting back up to the disheveled white alicorn.

He manifest a black, thick blindfold before firmly tying the handkerchief over her eyes. Tirek softly nibbled on her swiveling ears electing a surprised gasp from Celestia. Tirek knew he would enjoy this session. He then brought out the whip previously.

Now the fun truly began for him. Tirek raised the whip before lightly lashing her left thigh. Celestia yelped at the burst of pain. Confused with the new pain senses. The centaur then cracked the whip across her gigantic breasts. Celestia screamed feeling the sting linger. She bit her lip in an attempt to silence herself. The white alicorn wasn't sure what was causing so much pain, but it snapped her out of her own thoughts.

"Do I have your attention slut? From now on you will call me 'master' or 'my lord'. Now repeat these words until I say other wise: 'I am a slave. My only purpose in life is to be the best cocksleeve for my master's use. With this purpose, I will serve as Lord Tirek's, King of Equestria, personal cock slut for all eternity'."

Tirek bet Celestia's face must have a priceless expression right about now, but he needed to imprint this before he can move forward. Celestia's lips stood firm like she froze in place. She was brought back to reality with two quick cracks on the breasts and right thigh making her lewdly cry out. "I said repeat, dumb bitch!"

The whip lashes left a few red marks on her alabaster body, but they quickly healed due to the alicorns higher-than average regeneration. Her lips trembled, but the words fell out all the same.

"I am..."

Two more cracks across her back and wings.

"I am a slave. My only purpose in life is to be th....."

One hard slap against her sensitive vagina caused her to wail out in tremendous pain. She couldn't even cum due to the denial spell still in effect.

"Start all over, bitch, and don't miss, or stretch, a single word. Or else you'll get something far worse than a slap across the womb." Tirek growled.

That snapped Celestia right back to her predicament. Her heart skipped a few beat at the warning. "I-I am a slave. My purpose in life is to be th-the best cocksleeve f-for my master's use. W-With this purpose, I will s-serve as Lord Tirek's, K-King of Equestria, p-personal cock slut. For all eternity."

Tirek was very pleased of this development, so he decided to treat her properly. He trot up behind her squeezing and groping her funbags with expertise. She gasped at the sensitive touch especially since he whipped her tits just moments before. The centaur stopped his assault momentarily squeezing them firmly to stress his point. "Did I tell you to fucking stop?"

Running on adrenaline and pain, Celestia continued on reciting the degrading pledge to Tirek over and over. Each word was embedded into her memory with every sting of pain and pleasure that flooded her mind. A spike of fear ran through Celestia's body feeling the pledge becoming something more than empty words while she repeated its tune. The words became easier to say, with every passing verse rehersed.

Once Tirek felt that she was deep into the self-trance, he placed a magical recorder nearby before pressing the record button. His second phase was almost complete. "Okay, slut, you can stop repeating those words. Now, recite these words without leaving a single word out: 'I, Celestia Aurora, diarchy of Equestria, hereby submit myself, and all territories of Equestria under its rule, under Lord Tirek's possession. I, Princess of the Sun, co-ruler of Equestria, also here by decree and recognize, Lord Tirek, the one and true King of Equestria'."

This phrase manage to snap her out of her trance temperarily, but she didn't want to feel the horrible pain ever again. The alabaster alicorn wanted to be good.

"I, Celestia Aurora, diarchy of Equestria, hereby submit myself, and all territories of Equestria under its rule, under Lord Tirek's possession. I, Princess of the Sun, co-ruler of Equestria, also here by decree and recognize, Lord Tirek, the one and true King of Equestria." Celestia repeated with relative ease back.

Tirek smiled satisfied with the willingness to comply. "'With these decrees, I also hereby strip myself, my sister, Luna Aurora, my formal faithful protege, Twilight Sparkle, and the princess of love, Mi Amore Cadenza, also known to be Cadence, any princess titles they may have had before in the past. Any other ruling princes and lower princesses will also be stripped of formal titles as well'."

Fear and despair knot in her chest, but her experience said to continue on. A stray tear fell from underneath her blindfold. "With these decrees, I also hereby strip myself, my sister, Luna Aurora, my formal faithful protege, Twilight Sparkle, and the princess of love, Mi Amore Cadenza, also known to be Cadence, any princess titles they may have had before in the past. Any other ruling princes and lower princesses will also be stripped of formal titles as well."

Tirek smiled to himself. He reached over grabbing the recorder before saving the previous recording. The centaur tenderly caressed her face feeling he should reward her efforts. He carefully removed the blindfold. "Good girl. Now with a little bit of editing and timing errors done, It would be the perfect confession recording for my new kingdom."

Celestia's eyes shrunk further at the possiblity. "No, please, I'll do anything you ask of me. Just don't do this to them, please!"

Tirek's eyes flashed orange walking back in front of Celestia. "I thought we got over the backtalk. Apparently, the bitch doesn't learn."

He quickly grabbed something not far from a nearby coffee table before displaying it into view. It was a fairly large o-ring gag that looked to be mostly made of enchanted metal. Celestia's heart pound harder into her chest closing her mouth for all she was worth, yet her desperate attempt failed when Tirek used his magic to forcefully open her mouth wide. He spread her lips as far as physically possible. Tirek then inserts the the o-ring gag just behind her flat teeth securing the gag behind her head. Surprisingly, the large o-ring was able to keep her jaw uncomfortably apart no matter hoe hard she tried to bite into it.

Tirek trot around to face her front again before getting his growing dick ready for the main event. The white alicorn's eyes widen at the sheer mass and size of his cock. Tirek smirked. "A proper slut would be able to take my penis instantly, even physically unprepared. But since you proclaimed just how proud you are to become my 'cocksleeve', I decided I might as well humor my pet." Once he got his cock at full mass, he inched toward Celestia's awaiting mouth.

She tried to turn away from the impending zeroing cock. His magic quickly enveloped her head before leaving it perfectly still. She felt her life flash before her eyes. Tirek's flaring tip easily slid into her mouth making Celestia gag due to the sheer size. Her gag reflex never had a problem intercepting large food objects before, so she thought she just didn't have a gag reflex. Apparently, she does have one.

Tirek pushed further into her warm depths, tears of shame glistened her eyes. He pushed before half way in slowly watching her trying and failing to exspell the foreign appendage. He then buried the rest of his mighty cock with a single thrust. Another resounding gag echoed the chambers. Her eyes looked distantly, almost leaving consciousness, due to the lack of air. He pulled his cock fully out of her mouth, inches from her face, watching her cough profusely and gasp for fresh air in his magical grip.

"Just think, you'll get to enjoy all of my royal seed for the rest of your longevity." Before she could even think to respond, he roughly slammed his cock back into her warm throat, her chin hitting his thick round balls. A throaty groan escaped her stuffed lips. "Nothing else to worry about, but the next meal of my next load. A paradise for insatiable sluts like yourself."

Tirek quickly pound her throat with his mighty cock. Her eyes couldn't help, but roll to the back of her head. Between her yearning pussy, burtal vibrating aval cavity, the whip pains/pleasures, this treatment was an absolute turn on to Celestia's eroding mind. She eventually started sucking his cock with each thrust into her throat. Even when the air in her lungs was growing thin.

His magical grip broke instantly switching to grabbing her horn and manually thrusting her gullet into his thrusts. With the last of Tirek's stamina fading, he finally thrust balls deep down into her hungering maw showering her throat with ropes upon ropes of his glorious sperm.

In a matter of seconds, her stomach filled up. Spurts of overflowing cum splattered the floor below them. The taste of his cum was surprsingly pleasing and warm against Celestia's tounge. She couldn't help but swallow whatever rope of cum she could drink down. A minute passed before Tirek pulled out of her mouth. Tirek's eyes slowly reverting back to a piercing yellow. Her eyes were rolled, tounge lolling again lazily out of her mouth. Cum stain marks littered her breasts dripping down on her abdomen and thighs. Tirek also noticed she had passed out, occasionally a moan passed her lips.

Tirek glacnced back at Celestia fire burning in his eyes. "I've always hated you. All that comes out of your mouth is a filthy pile of lies. Maybe stuffing your face with the truth will help you learn your place."

He went to examine the recorder for further editing. Eventually, he walked out of the shape pentagon, the door shutting behind him as he tinkered with the data inside the crystal.

Tirek simultaneously opened a portal back to Canterlot Castle, two-thirds of his improvised plan completed. Now, there was one last 'problem' to take care of before the final blow to Equestria could commence.

Author's Note

This.... came out longer than I first thought it would be. And it's the first time writing this type of style of porn too, I suppose. Huh. Well, there is that daily dose achieved. I was challenged to write something brutal, and your bet is paid. Though, I think it nicely compliments the theme in this fic.

Huh, would you look at that, it's Halloween. Not sure if this chapter would be appropriate for this holiday, but screw it. It's up. Hope you enjoyed this one.

On a side note, longest writen smut I have up-to-date.
Next chapter.
