Twilight moved slowly down the glowing corridor. Her panties had slipped off her ankles a few steps before. Her T-shirt was in the way, and so she pulled it off over her head and tossed it aside. Shining was in his room. Shining Armor was waiting for her. She had to go see him.

She cupped her breasts as she walked. They weren't flat, but they were still a little small. She wanted bigger ones, like those Cadance or even Celestia had. She'd always wanted big ones. She'd even gone and researched how to get them, but she always came up short when she did. Maybe Shining could help her. He'd helped Sunny, after all.

The hallway was littered with other clothes. A large sweater. A diagonally cut skirt. A pair of striped socks. A ripped blouse. A crumpled T-shirt. Panties and snapped-off bras and other tatters of cloth, all leading her towards Shining's room. The hair was hot, and heavy, forcing her to take in deep breaths, yet it felt cool against her damp pussy lips. The musk of sex grew stronger the deeper into the castle she moved, and soon she could hear moaning too.

So many voices. It was hard to tell them apart. Not that it mattered. They were all the same. They were all there for the same reason. For Shining to fuck them. She could have her voice join in with them. It would be good. It would be okay. They'd make it legal if need be. She could kiss Shining. She could love Shining. She could bear Shining's child. Was it really so bad?

She stood in front of the door. It was a thin, wooden door, plain and weak, yet still it held back most of the sound. She could only dream of what it would be like on the other side. She could feel the magic thrumming beyond it, shaking the air with its sheer intensity. She should have been worried. She should have been confused. On some level she knew all that. She could feel dozens of different mental alarms going off in her brain. And yet she could not care for them. It was like moving in a dream. It was like being sick and too filled with drugs to even realise what she was doing. It was like she was just a character in a book, playing things out and watching them happen without control at the same time.

Twilight Sparkle opened the door.

Everything hit her all at once. The smell of three days of constant fucking in a closed room struck her almost physically as the air rolled out of the open door, fogging her brain and making her thighs clench. With it came the furnace-like heat that washed over her, making her skin tingle and sweat all over as it blanketed her like a wave. The sounds grew louder and clearer, no longer muffled moans but now sharp cries of ecstasy that overlapped with each other, too many to tell any of them apart. Other sounds became clear too, wet and meaty, sloppy and obscene, like flesh grinding against flesh and bodies smacking violently against one another.

The light in the room was bright, almost blinding compared to the half gloom she had been in. It was like the glow itself was singing, a sound clearer than all the other ones, bright and evident above the chaos as if projected not to her ears but directly to her mind. It beckoned her closer, and with light and swaying steps she obeyed. She could not even think, she could only follow as the light commanded her to step in.

The door slid closed behind her. Twilight sighed. Her mind lost some of the fog shrouding it, and the scene before her resolved itself into something she could properly see.

Shining was the first thing she saw, the one thing her eyes focused on. The centre of the room and the most important thing in it. He sat upon the edge of his bed like he was sitting on a throne, his fully naked body gleaming with sweat and other fluids in the light, every detail of his muscled limbs and torso vividly visible. Twilight's eyes focused elsewhere however.

His cock was standing firm at full size, and the sight of it took her breath away. It was massive, even bigger than she'd imagined it, thick and long with two huge, heavy balls beneath it. And wrapped around his cock like a set of five rings were the Elements of Harmony belonging to her friends, placed so their gems were on the underside of his shaft. The golden necklaces had reshaped and tightened themselves into proper bands that fit his girth perfectly.

Looking up from the slick tip of his magnificent cock, Twilight's eyes trailed over his chiselled abs, his muscled chest, and his wide shoulders. Upwards still, to his confident smirk, his eyes shining in the light, and on his head the Element of Magic sitting almost like it was his own crown, if slightly askew. The sight of it there felt wrong. The sight of it there felt right. Twilight didn't know what to think, and so she did not think and merely looked on. His horn was lit by a glowing line of magic, and Twilight followed it with her eyes.

She found Cadance, a tight collar wrapped around her neck. She was on the bed behind Shining, kneeling, pressing her pierced chest into his back and with her arms over his thighs, planting wet kisses on his neck. Her wings would quiver lightly from time to time, her eyes were unfocused, and her breathing seemed slow.

Twilight's vision widened a bit further than before, more of the scene becoming clear to her. There was Rainbow kneeling before the bed on one of Shining's sides, fingering herself roughly as her other hand held one of Shining's balls that her mouth and tongue lapped desperately at. Her nose was buried in his crotch, her expression completely hidden. Twilight felt something was wrong, but the sight was too hot to care.

On the opposite side, Applejack was doing exactly the same. Her strong, roughly built body was slick in the light, showing the size of her muscles and what little definition they had. Her blonde mane was unbound and splayed over her back and shoulders, and her tail was spread out on the ground. She held Shining's ball like she would an apple she did not wish to damage in any way, and licked it slowly and sweetly. Her fingers toyed with her cunt at a slow and careful pace, and her hat sat askew on her head, obscuring her eyes.

Twilight looked farther up. On the bed, on the same side as Applejack was Fluttershy. She was bent forward, with her ass sticking up behind herself and her fat tits pressed hard beneath her. She had her face planted directly into Shining's cock, with her tongue out, and more than licking it she was practically running her whole head up and down, smearing herself against his length. On the other side, Pinkie was doing exactly the same thing.

Up still. One on each side, Rarity and Starlight were kneeling besides Shining, facing each other and him. Each with one hand fingering the mare bent over on her side, Pinkie for one unicorn and Fluttershy for the other. Their horns were glowing, thrusting shafts of ethereal energy into each other's marehoods. Their free arms were wrapped around Shining's neck, with their hands caressing his muscles, and their heads leaned towards him to kiss and lick his shoulders and chest.

In a corner of her vision, Twilight was vaguely aware of a misshapen glowing crystal that was lighting the whole room. It was huge and it had fully enveloped and consumed the desk once there, and it was digging its roots into the walls and and floor and ceiling, merging with the castle and pouring magic into it. It was stuffed full of so much magic she could taste it, and she knew for a fact she should have been worried about it. But she could not care even a bit.

There was only one thing she could care about at that moment. She took a step forward, then another, then sank to her knees. It was selfish, perhaps. Maybe not the act itself, but her reasons for ultimately choosing to do it certainly were. But the images from the book filled her head ceaselessly, pushing out everything else, and she couldn't help but see Shining in them, and all the mares around him, and herself. She looked up to her brother towering over her even as he sat, and felt the last of her hesitation drain away. "Shining Armor..." She tasted the name on her lips. It felt sweet. "I accept." Her heart fluttered with joy, even as her mind told her things didn't feel the way they were supposed to.

Shining looked at her with interest and a clear air of superiority, as the other seven mares kept pleasing him. "What exactly do you accept?" he asked in his warm, diplomatic tone.

Twilight breathed deeply, shuffling on her knees. "I accept to be with you," she said. Words spilled out faster as she let herself go. "I accept to being your bride. You partner in love, and in bed if you will want me there. I accept to be the mother of your child if you were so to wish. I accept to love you, my brother, my Prince." She looked at him feeling drunk on the heat of her blush. "I love you, Shining."

For just a moment, impossible to see from where Twilight was kneeling, a vein throbbed in Shining's forehead. Slowly as he talked, but surely, his voice got just a little deeper, harsher, and cold. "Is that all you agree to? Is there not more you wish, and more you're here to subject yourself to? Do you truly understand the conditions you are to place yourself in?"

"I..." Twilight hesitated, squirming in her heat. The mental walls were there again, keeping her trapped, and she couldn't find the way forward in her thoughts. Luckily, Shining was there to guide her.

His voice was commanding the next time he spoke. Not like a Captain encouraging his troops during training, but like one ordering them before battle. It was firm and rough and it permitted no retorts or disagreements. It tore through the fog of Twilight's minds and forcefully dragged her along the way in the maze of her thoughts, through the only path the walls within her allowed. "You are here to give yourself to me. You are here to relinquish your role as Princess and ruler, and be mine. That is what you wish." And Twilight followed, ensnared by his words, merely relieved she could finally find a path out of her confusion.

Shining continued. "You are unfit to rule. That is evident, and it has always been. You are not a ruler, Twilight Sparkle. You never were, and you never will be. It is only natural for you to choose to follow and obey someone who is. Someone like me." His cock flexed, drawing Twilight's gaze and keeping it. "You have always desired submission. I have seen the way you crave sexual domination, and the way that book fuels your lurid fantasies to the point of keeping your attention through the days. Deep down you're a slut, who cares about being fucked much more than she cares about the well being of her subjects. You could never rule in that state, and you never should be allowed to." There was anger in his voice, and his breath was growing hot as his muscles flexed.

He spoke again. "You are weak. Mentally, and physically, you're inferior. You could never rule. You could never withstand the weight of the crown." His lips shifted to a cruel smile. "That is why you must cast it away. That is why you must surrender yourself to me, wholly and utterly. It's what is right, and it's what you want. Admit your inferiority, and your desires, and concede your being to me completely. I'm not sure you can comprehend the magnitude of the submission you are to undertake, but I can assure you it is what you must do, and what shall bring you happiness." He brought a hand to the Element of Magic and made it skew the other way with a touch. "This crown still belongs to you. Cast it away, and all it represents with it. Make it mine, as your friends have done with their Elements. Make yourself mine. We shall not rule as equals, but I your King and you my concubine."

Twilight shuddered in pleasure at those last few words. How could she do anything but accept? When every secret fantasy and perverse desire she'd immersed herself in was suddenly shown to her as a tangible possibility, how could she ever choose not to go through with it? Shining was everything she had dreamed of. She could have that deep, true submission she'd come to crave, and along with it she would be doing the right thing too. It did not matter that she knew, logically, that what he was proposing was wrong. It did not matter that the excitement she had felt reading the book had come from the knowledge that those acts were forbidden and immoral. Nothing mattered to her, and that knowledge that should have stilled her actions and thoughts washed over her harmlessly, bouncing against the brilliant glow that filled her mind and guided her.

"Yes." She whispered the word, as if all her energy had already been drained from her. "Yes," she repeated, louder, to make sure Shining would hear her. She wanted it. She wanted it in so many ways. She wanted to love her brother and Cadance and finally be intimate with those she trusted most. She wanted to be free from the burden of being royalty. She wanted to set a good example and make Equestria a better place. She wanted a King to dominate and fuck her hard. It all came together so perfectly. It was like a dream. "Yes."

Shining smiled even wider, breathing deeply as the remaining mares ceaselessly pleasured him and each other and themselves. "Do you believe you deserve this yet? Do you believe you have earned your new role as my plaything and property?" He took the Element of Magic from his head and held it in his hand. "For one as yourself, submitting is a reward, and even more so submitting to me. I am the greatest King and ruler you could find. I can give you pleasure more than anyone else could. Your life under me will be the greatest existence you could ever wish for, and I alone can make it your reality. Endless, incomparable pleasure, the kind only I can give, as you're forever freed from all worry. So I ask you again. Are you deserving of partaking in servitude? Are you deserving of your liberation?"

Twilight's eyes unfocused and focused repeatedly, the closest alternative to darting around when they were glued to Shining's cock. "I..." Her heart was beating faster and faster and her thoughts were too messy for her to catch and hold on to any one of them. "I..." She swallowed as the answer became clear, and slowly she bent down low, pressing her face against the floor. "I do not know. It is not my place to judge, or to decide. Please. It is all I could ever wish for."

Shining laughed at the sight, and his cock throbbed. "Already you forsake your ability to choose and place yourself in someone else's hands. Utterly incapable of thinking and deciding for yourself. But I suppose at least in this you are correct. It is my place to decide whether you are worthy of me or not, and mine alone." He leaned back into Cadance, and feigned a thoughtful expression. "So, I suppose I should examine your case.

"It is true that you should belong to me. As an alicorn, and as my sister, it's in your destiny to be mine. It is also true that I would be doing ponykind a service in taking over your duties, freeing them from your incompetence in favour of my greatness. Moreover, I do intend to feast on your energy as I have with my first bride, as it is only right for me to do so. However." He let the Element of Magic fall to the floor and roll a little towards Twilight. "You have committed a great deal of mistakes in my time here, and that cannot go unacknowledged. You have wasted my time. You have forced me to partake in a facade to hide my greatness, and even caused me to go without Cadance's continued nourishment for hours at a time. You have required me to construct lies and schemes so your weak and troubled mind could be shown the truth in a way it could understand. For all this you must apologise, and for all this you must be punished."

Twilight, still prostrated on the ground, shook with every word as if it was a blow against her body. Shining's voice shone with blinding truth within her mind, stomping anything else as it imposed itself upon her. It was like standing before a divine revelation, his every word unveiling new truths that she had never known yet were evident and perfect. "Yes! I'm sorry, I'm so sorry my King! I am unworthy, I have failed to submit as I should have, I have wasted your precious time! I apologise! I submit! Punish me. Punish me as you most see fit, I beg you. There is nothing else I can do but this. I offer myself to you." She pressed herself even harder into the floor, tits mashed against the crystal, stiff nipples burning with need as her sex ached.

Shining growled in pleasure at her display. "At least you know your place well. Raise your ass, slut, and keep your head low where it belongs. I won't allow you to even look at me until I think you've atoned!"

Twilight did as she was told, desperate for what he promised, desperate to become his. Scorching pleasure and lust coursed through her veins, dictating her every action and overriding her every thought. Keeping her face against the floor, eyes closed for fear of even accidentally looking at Shining when she was not allowed, she slowly straightened her legs until her ass was up in the air, with her tail to the side to fully expose her throbbing, leaking marehood. Her back hurt, but she endured the pain. She deserved her punishment, and craved the reward at the end of it.

Shining spoke loud above the moans of the mares around him. "State what you truly are, and the sins you've committed." His horn shone bright, lighting the room even more as the pink of his magic mixed with the blue of the crystal's glow.

Twilight felt her nethers burning as she was commanded to expose herself, but she did not hesitate. "I'm a slut, a weak willed pathetic bitch unfit to rule, who cares about her brother's cock more than she cares about her subjects." At that moment, Shining's magic struck her behind like a whip, leaving a stinging mark that quickly turned red where it had hit her. Twilight screamed in pleasure and pain, and her pussy clenched.

Still, she continued on. "I'm a horny, desperate girl who wants to be abused and dominated and cums to the thought of being degraded and controlled." Another blow to her asscheeks. Twilight's mind fogged and her breath spilled heavy and hot from her throat. "I'm a worthless mare whose only purpose is to serve her King's every whim." Another strike. She did not even know where she was finding the words as they emerged from the buzzing chaos swirling around her thoughts, and yet they felt so right and perfect on her tongue she couldn't help but keep going.

"I was stupid and blind, and I wasted my King's time." Another hit. Tears of pleasure gathered at the corners of Twilight's closed eyes. "I refused to submit to him right away." Another. Her pussy leaked. "I wasted his time and forced him away from his deserved pleasure." Another blow. Twilight moaned and shook all over. "I acted like I was above my needs." Another. "I tricked others into thinking I was anything other than a desperate slut!" Another one. "I lied to myself about my true wants and my true purpose." One more. Twilight was screaming. "I accepted and upheld a world without my King at the top of everything, where he belongs!"

Again, and again, and again. Blow after blow, strike after strike, Shining's magic lashed out, leaving Twilight's ass a criss-cross of heated red lines pulsing with pain and her thighs drenched in her juices. Her face was a mess of tears and drool and sweat and still she pressed it hard into the floor, knowing that was her place, knowing she deserved to be low and degraded, nothing but property for her King to walk over if he so chose. Her whole body hurt from the punishment and the strain, and yet she was heated with pleasure like never before at finally experiencing submission like she'd come to crave.

Shining spoke again and he blazed clear through the maelstrom of her emotions. "You have not been punished enough. No punishment I could give you would be enough to pay for your failings! You have failed as a pony, you have failed as a Princess, and you have failed as a sibling. You have come crawling to me conscious it's all you can do, and again you have failed as already you have declared yourself mine without my permission. I have hurt you, and yet the pleasure a masochistic bitch like you derives from my hurtful touch far outweighs the pain I can inflict. No amount of punishment could ever be enough when you would only rejoice perversely at being subject to my will!

"But I am a merciful God, to all those beneath me who know their place. I will show mercy to you, and to all those I will free from you as I take you into my harem. None shall ever need to depend on a pathetic, weak pony like you, who would betray them at the first chance of submitting to me. You will never think for yourself again, and you'll never make new mistakes! You shall be an extension of my will, as is right for you to be." His voice boomed in the room and in Twilight's mind. "Rise and look to me, and make the submission of all you were absolute!"

Twilight was a wound-up string, getting tighter and tighter with every word Shining said as she realised where he was heading, and at his final command her back snapped up and her knees gave out and her eyes shot open and she screamed, cunt gushing beneath her, kneeling as she took in the sight of Shining's magnificence. She tried to say yes, but all that came out were incoherent little moans. Her thoughts were scattered as hooks of blazing lust dug deep into her and dragged her forward. Shining looked to her with lust for what she was to be and disdain for how worthless and pathetic she was, and spat on her, and Twilight felt her skin burn where his spit landed and her mind go blank at the humiliation.

Moving on all fours, breathing deeply like drunk on the smell of sex within the room, Twilight crawled forward towards Shining. She had eyes only for his beautiful, massive, throbbing, leaking cock, and ears only for the deep sound of his powerful beating heart. She stopped halfway there, though, as her hand hit something. Unwillingly, she looked down. Her crown lay on the floor, discarded, sullied with sweat and other fluids.

But it wasn't her crown. It couldn't be her crown. She did not deserve to rule over anything. It had to be Shining's, then. Twilight smiled as she took the Element of Magic in her hands. She looked to Shining's cock again, already decorated with the other five Elements. Of course. It made such perfect sense.

She shuffled forward on her knees until she was close enough, until the musk of Shining's cock hit her nose like a hammer and made her mind go white and her mouth spread as she drooled. There, swaying with dizziness, she held the Element forward, upside down. She rested it at the base of Shining's cock, with the gem between his balls and the arms of the tiara reaching around them. The gold metal shifted, reshaping itself to fit its new purpose and place.

Twilight let go of the Element and leaned back. The purple gem of her cutie mark rested cradled over Shining's balls, framed by gold that had shaped itself to lean into them. A band of gold wrapped around the base of his sack, and another around the base of his cock. Twilight admired all six golden rings and gems upon his shaft, at equal distances from each other. The perfect image of his new order over the old one she'd foolishly upheld. She stared up past his cock, finally into his perfect eyes. She spoke barely audibly, enraptured by the beauty of her King. "I'm ready."

Shining grinned, cruelly, lustfully, mad with power, and his magic reached out to her. It touched her horn. Twilight moaned deeply as she felt herself being drawn to him, as if leaving herself behind.

And in that moment, that instant of separation, the veil cast over Twilight's mind fell, and the lens placed over her thoughts cracked. In that one moment she saw everything as it truly was.

She saw the magical filters her mind had been drenched in, the buzzing blue light drowning her reason and choking her thoughts. She saw the way she had been forced to see things differently, the way her own emotions had been twisted and a path had been traced for her as walls were built up to prevent her from even thinking anything else. She saw her confusion over the previous days as the artificial, magically enforced state it had been, and her new thoughts as something alien to who she truly was. She saw the hollow, manufactured ecstasy within her friends' eyes, and the horrifying, twisted nature of the situation her brother had built, drenched in lust and devoid of morals.

And then the moment was over, and Shining Armor's mind slammed into hers before she could do anything else.

Twilight's senses exploded with an overload of information both alien and familiar. Memories at a far faster rate than it should have been possible for her to experience rammed their way into her, overriding her own. She saw all her moments with Shining from his perspective, warped by his own mind until they were all but incompatible with her own way of thinking on a basic level. And then new memories, memories that were only his, and memories of her friends and Cadance from their own minds too.

Twilight's personality and being was torn, penetrated, melded to other far stranger and wilder things reconstructing her mind in accordance to laws unlike those her life had been lived by. And then she was pulled deeper still, in spaces she could not conceive, in a darkness and fire she couldn't make sense of. Deep, deep into Shining's own mind, into the impossible geometries of the temple of his own ego.

She could not possibly understand what was all around her. It came to her as strange lights and twisted landscapes that bent logic and physics, colours her eyes could not see and sounds she could not hear. It came to her as the incomprehensible, a sea of information irreconcilable with her being, with too much power behind it for her to do anything but succumb to it.

And so she did. Dragged along spiralling corridors of thought, battered by winds of knowledge she could not grasp, winding through the nonsensical halls of a mind that was beyond her own. A mind that had transcended her own. Yes. Within the chaos, at the heart of it, she found undeniable truth. What she was in was the home of a being greater than her own, greater than she could ever possibly hope to be. Within it all was Shining Armor, his superiority unquestionable, his lordship absolute. He withstood and he ruled over the storm, and he was the storm. Shining Armor was a King, a God, a flawless being blessed with a vision of truth so perfect she could not even partake in it. All she could do before his superiority was submit, as all should.

And so she would.

Twilight opened her eyes again. She was herself. Her true, new self; the self she had always been meant to be and had instead been too blind and stupid to know. The self it was right for her to be. And it felt good. It was pleasure beyond compare.

Twilight moaned. She was on her back atop the bed, her legs bent up with her knees pressing into her shoulders. And she was being filled. Stars, she was being filled. Her eyes focused and all she could see was the blur of Shining's mane and eyes as he thrust into her, and the blinding glow of the ethereal link between their horns, and the subtly visible image of the glowing hearts within her own eyes.

Shining siphoned more of her power, and Twilight felt good. To have herself drained, to have her magical reservoirs plundered, it was a form of submission and defilement deeper than anything she'd ever dreamed of. Every drop of energy forcefully ripped from her was a hit of pleasure, a star exploding in her mind, the combination of the humiliation at what she was suffering and the actual physical response her body had been instructed to give out making her pant and shudder and lose herself.

Shining thrust into her at a brutal pace. His hips slammed into her own over and over, reddening her flesh, coating her legs and thighs and ass with her juices as she gushed from her sex like a broken faucet. His cock was massive, thick, long, and with every movement she felt the gems upon the rings wrapped around it running over her insides, and the cold metal of the ring around the base hitting her clit. He used her like a toy, her whole body pinned down under his strength, bent unnaturally for the sole purpose of him fucking her. Of him breeding her like an animal.

Her wings were pressed between the bed and her back. Her horn was completely subject to the siphoning spell feeding ceaselessly off of her. Her limbs were trapped, arms pinned beneath her legs and legs held down by Shining's muscled arms. Her mind was useless, constantly bombarded by explosions of ecstasy as Shining used her for his own pleasure and made her body quake with pleasure of its own. Her sex gushed, her lips drooled, and her eyes danced directionless and uncoordinated in their sockets.

All she could hear were her own moans and the sounds of Shining fucking her, louder than any thoughts she may have had. All she could smell was the scent of sex, the musk of Shining virility and the smell of her own submission and pleasure. All she could think, in fragmented half thoughts between white hot sparks of bliss, was pleasure and submission and sex. She could not say any words, but only moan. The pleasure was overwhelming, all consuming, and Twilight willed herself to drown in it.

Shining's motions grew faster. His balls and the crystal placed onto them slapped against her ass with every thrust. Twilight knew what that meant, as it was her duty to know such a thing as her King's devoted slut and slave. Her heart beat so fast it felt like it wouldn't be able to keep up with its own pace and her whole body shook with anticipation and excitement. Her King would breed her. She would bear him a child, an heir to her own role, a future bride. It was her highest honour and duty besides obeying his will and tending to his pleasure. It was her happiness above all else.

From somewhere beyond the core of Twilight's world, the point of pure pleasure that were her and Shining's bodies entwined, and within the sphere of sex and submission around them, where Shining's other slaves writhed in bliss, Cadance's magic reached out. It reached deep within Twilight, around Shining's cock and deeper still, to the core of her purpose as his bride. It reached, Twilight knew without knowing, to ensure she would give their King a child, and to ensure it would be a daughter.

Shining came. It was a flow of hot, thick, heavy seed, pouring within Twilight and igniting her nerves with searing ecstasy wherever it touched. Twilight came, mind empty, body quaking and marehood spasming around her King's shaft, as still Shining shot load after load of his essence within her. She came and she screamed and she was his, and that was all she knew as she felt consciousness leave her again.
