Reclaiming his Empire; Claiming his Subjects

Sombra made his way along the corridor, his hooves clacking against the crystal surface of the floor. His cape hang from his shoulders, floating behind him, and his armour shone as it reflected the light coming in from the windows and bouncing off of the walls.

A guard snapped in position as he passed by his side, standing at attention, his eyes glowing green and his expression emotionless.

A few steps after having passed him, Sombra stopped, smiling to himself, and turned back, walking towards the stallion. Without saying a word, he grabbed him by the neck and pushed him against the wall.

The guard did not react, despite being denied his breath.

"Impressive," Sombra commented, without letting go of the pegasus. He tightened his grip around the stallion's throat, and asked, "What would you do if I were to try to snap your neck now?"

Despite the lack of emotions on his features, a single bead of sweat fell from the pony's forehead.

With a chuckle, Sombra teleported himself and the other away and into what had once been the royal bedroom, now his own private quarters. Throwing his captive on the bed, he shot a bolt of red magic at him, burning away his clothes and forcing his disguise spell to fall apart, revealing the black chitin covering his body and the insect-like qualities of his face and structure. "Pretty clever, I have to admit," he commented.

Thorax made one last attempt to escape, firing up his horn to shoot a blast at the wall while dashing for it, but a moment later he was once more on the bed, clutching his head, him and his spell having bounced back against an invisible wall of energy, black and red sparks still dancing around his horn.

"You know, I'd found out about you pretty quickly," Sombra said, reforming from a cloud of smoke, naked at Thorax's side, and forcing the changeling's lips into a kiss. Breaking away, a trail of saliva connecting their mouths, he continued, "I could have caught you sooner, but I had other things to do. Not that I would have let you get away." He gripped the other's throat, stopping him from speaking, and began to grind himself against his body. "It is a shame traditional mind-control magic doesn't work on your kind, not enough for me to use it effectively on you without breaking you outright at least. But I guess it'll allow me to have some more traditional fun." He forced another kiss, exploring Thorax's mouth with his tongue.

Thorax tried to wriggle away, turning, only for Sombra to pin him down on his front, easily holding the smaller creature still as he moved to bite the back of his neck while grabbing the changeling's wrists and holding them above his tail.

Keeping his prey there, and forcing him to lie face down, ass up, the unicorn wasted no time in immobilising his hands and neck with magic, the same red glow of his telekinesis wrapping around the changeling's shaft and beginning to pump and stroke it. "Believe me," he said, as he took hold of Thorax's hips and started to grind his stallionhood in the crack of the changeling's ass, "by the time I'm done with you you'll be begging for more."

Thorax tried to speak, but was silenced by another wrap of solid red magic.

"Now, let's see..." Sombra took a moment to pause, the tip of his shaft resting against the entrance to Thorax's ass. "I think... Yeah, this should work." His horn lit up, and a red aura enveloped the changeling's.

Without warning, Thorax felt an outside force seep into his horn, a fire flaring up in his head. Outside of his control, his magic began to work on its own, obeying the intruding energy's command, and his body began to change accordingly. He could not quite tell what was being done to him, between the aching in his head and the seemingly subtle nature of the changes, but he feared he would find out soon.

Satisfied with the changes, Sombra finished by placing a ring of black crystal around Thorax's horn, preventing him from reverting the changes, then with a flick of his horn removed the band of energy keeping the changeling silent. "Well, what do you say?" he asked, stroking his captive's wings with a hand.

"What have you done to me?" Thorax asked, trying to look back towards the unicorn.

"You'll find out. Next question?" Sombra replied, playing with the changeling's tail.

"What have you done to my friends?"

Sombra smiled. "Don't worry about them. You've got enough to worry about for yourself already."

Thorax growled. "You monster." A spike of pain shot through his head, and he howled, biting his lips.

"Oh, that's not nice. Didn't your friends teach you any kind of manners?" Sombra mockingly asked, shaking his head in feigned disappointment.

Sputtering, his breath rough, Thorax coughed, then took a breath to calm himself. "You're not going to break me."

"I could," Sombra very simply replied, grabbing the changeling's neck and pressing just enough for the chitin covering it to creak. Letting go, he continued, "But I won't. For that, you should be glad."

Thorax bitterly chuckled.

Sombra chuckled back, a genuine smile on his face. "Say thank you."

"Thank you," Thorax said. Before he had time to process his own actions, a rush of pleasure washed over him, and he failed to hold back a moan.

Sombra moved closer to him, lifting his head up with a hand and turning it to face him. "Well? How was that, slave?"

At the mention of the word slave, another jolt of ecstasy coursed through Thorax's body, his shaft now standing at full mast and already leaking precum down on the bed.

Looking down, Sombra noticed the drops falling from the other's cock. "Oh, that's not good at all." His horn lit up, and a small red crystal formed at the tip of Thorax's shaft, plugging it, while a ring of the same material sealed itself at the halfway point of the changeling's member, and a second one formed at the base of it. Then, as Thorax groaned below him, he turned him around to place his face in front of the stain he'd left on the bed. "Clean it," he commanded.

Breathing slowly, Thorax remained silent, refusing to obey.

The unicorn clicked his tongue. "Are you disobeying an order from your King?"

Pain once more flared in the changeling's mind, searing white, piercing through his skull. Driven to tears, his struggles futile, Thorax resigned himself and inched forward, licking away his juices and sobbing quietly.

Sombra patted him on the back. "Good boy."

The pleasure caught Thorax by surprise, and he moaned again, his cock throbbing in its restraints.

Sombra chuckled, licking his lips. "Roll over," he said.

Thorax remained there, crying but defiantly refusing to obey the unicorn.

Shaking his head in disappointment, Sombra began, "Are you disobeying-"

Only the first shadow of pain had began to form into him, but Thorax immediately rolled on to his back, his breath ragged, fear in his face, and shame at having so easily given in. He should have been stronger. But he couldn't, he just couldn't take it. He'd never been the strong one.

"Good boy," Sombra praised him.

Thorax bit his lip, refusing to moan this time. His cock appeared painfully erect, pushing against the rings of crystal around it. He wasn't doing it for this. He obeyed to avoid the pain, but not for the reward. He wouldn't give in like that. He'd run away to not be a pawn in Chrysalis's hands, he wouldn't become one in Sombra's.

The unicorn moved a hand to stroke Thorax's chest, gently rubbing his palm against the changeling's chitin. Then he moved a finger to his chin, forcing the other to look at him. "You like what you see, don't you?" he asked.

Thorax just stared at him, panting heavily.

"Don't lie to me. I've peered into the minds of almost every pony in this castle, I know about the looks you threw at Shining Armor. I know you can't help but feel attracted to me." Sombra stroked the changeling's horn. "Why fight it? You can be happy, and so can all your friends. Just accept me as your King."

Thorax swallowed, but he dared not answer back, fearing another punishment.

"What's so wrong with giving in, Thorax?" Sombra continued. "Everyone can be happy. Everyone can be mine. Why try to resist. Why suffer and waste energies, when submitting is so much better? Why would you choose needless pain for the sake of a useless struggle, when you can instead have pleasure? On what grounds?"

Thorax swallowed once again, finding the courage to reply. "For my friends. For the ponies who took me in and accepted me as one of their own. I have heard them speak of you, of the ways you've made them suffer. I won't betray them."

"Like you didn't betray the hive?" Sombra asked.

Thorax looked to the side, drawing back.

"They were your family. You were one of them. But you ran away, and befriended their enemy. You betrayed them. And you know why, Thorax?"

"They were evil!" the changeling yelled, tears swelling in his eyes once again. "They were monsters."

"Bullshit!" Sombra replied. "There is no such thing as good or evil. Only points of view. Ponies are in control, ponies get to decide. But there is no moral high ground in this world, only power. What they have done to your race, what they have done to me, is that not just as terrible as what we have tried to do to them? But they won, so they get to play the good guys." He grabbed Thorax's throat, choking him, and lifted him up to stare into his eyes. "Do you want to know why you changed sides? It wasn't about good and evil. It was a matter of selfish desire. You feel better with ponies than you did with changelings, so they are good. That's all there is to it."

Thorax tried to shake his head, crying.

"You were always a weak one, Thorax. Too weak to build your own place of authority. And so you had to run, because the only way you could be satisfied was serving under someone else. You just traded a Queen for a Prince, but deep down you're still the same obedient little drone. You only care about what's best for you, and right now you believe that's your friends," Sombra continued.

Thorax's face was a mask of desperation. Sombra's words should have made him furious, but the crystals placed around his shaft had been sending waves of pleasure into him all throughout the unicorn's speech. He cried in shame and fear, as the idea of believing those words to be his truth borrowed itself into his mind, tantalizing and so so easy to accept.

"Admit it, Thorax. This is who you are. You're a weak and pathetic worm who crawls from place to place in search of the best Master to obey, and who throws everything he said he believed in away the moment he finds a better one," Sombra commanded him, letting go of his throat.

Thorax stared at him, desperate and lost, whispers in his mind telling him to give in, tears streaking his face.

Sombra grinned at the changeling. "Disobeying your King, slave?"

Thorax began to howl in pain. Sputtering, he blurted out, "I'm a worm! I betrayed my Queen, and I did it just for myself! I live just to crawl beneath the best owner I can find, I need to serve them in any way they desire and I don't give a fuck about who they are or what they believe is right!"

Sombra moved closer to him. "Good boy."

It was as if something inside him had broken. He should have been cumming, but something held him back. Forever stuck in that moment just before climax, so good yet just a moment away from something better, forever torn between the pleasure he was feeling and the maddening need for the release just a hair's breadth away.

"And now, I'll give you something better than any of those ponies might have ever offered you." Chuckling, Sombra lifted up the changeling's legs. aligned himself and began to thrust inside him.

Thorax's mind went blank. Pleasure he'd never even imagined possible flooded his body, his entire being ablaze with bliss and ecstasy. Time lost all meaning, as he entered a world beyond anything he'd ever experienced. Mere orgasms, normal sex, couldn't even compare to it. It was something different, something beyond, and it was so much better than anything he'd ever known. Pure bliss, wiping away anything else. The best thing he'd ever known. He lived to serve the best Master he could find, and Sombra had just given him something far better than friendship. He would serve his King, any way he wished.

Sombra smiled to himself as he pulled out of the barely conscious changeling, some of his cum leaking from the other's hole, then he took a step back, his clothes reforming around him. With a nod of his horn, the ring around Thorax's turned to dust, while those around his shaft slowly began to shift and change, wrapping around the changeling's member and constricting it until they formed a small and tight chastity cage at the base of his crotch, shiny grey metal decorated with rubies. Appearing from clouds of purple smoke, see-through strands of green fabric wrapped around Thorax's limbs, face and waist, then both of them disappeared from the room in a flash of red light.
