Dusk was beyond ecstatic, as he sat in his crystal throne, Umbra at his side, he gazed at the former Elements of Harmony. They were now properly dressed, with Rainbow Dash now wearing Dusk's emblem on her tight bodysuit. Though they had offered some level of resistance, they all fell under Dusk's control, and now was the next step. As Dusk rose from his throne, all eyes fell upon him with both worship and desire.

"My loyal subject, now is our time." Dusk announced, his voice echoing throughout the halls. "With the Elements under my will, the time has come to enact our final steps. We leave for Canterlot."

"And what shall we do my King?" Umbra asked, reveling in her master's superiority.

"There are still pockets of resistance around Equestria. None have the full power to face me, but I shall leave no stone unturned." Dusk responded, turning his gaze to two guards. "Prepare my carriage."

The flight to Canterlot was long but felt short. Dusk used this time to look out over Equestria. Since his corruption, Dusk has spread his influence far and wide. Though he knew there were still some who defied him, he would seize them soon enough. With Canterlot in sight, Dusk's lips curled a little at the sight. Canterlot, the center of Equestrian power was covered in countless changeling eggs and honeycomb hive scattered about. During his conquest of the Crystal Empire, Dusk recruited Chrysalis and her kin with the promise of Canterlot. As the massive carriage landed, Dusk along with Umbra and the Elements were greeted by changeling guards.

"Take us to your Queen." Dusk instructed, to which the changelings bowed and guided the group to the palace.

Within Canterlot palace, the sounds of click, buzzes, and hums filled the slick green halls. But the sound of bells then struck at Dusk's ears. When reaching the main doors, the guards opened the door allowing Dusk and his group entry. Within the throne room, Queen Chrysalis sat upon her throne, her regal dark green dress only complimenting her curved and luscious body, and how she wore her swamp green mane only drew attention to her hypnotic cleavage. At her sides, collared and chained to the throne were Princess Celestia and Princess Luna. Both were naked and covered in large amounts of the green slime substance, but neither appeared to be making any attempt to leave their situation. Dusk's attention then was turned to the source of the bell sound. It was Princess Cadance, naked and being violently fucked by a rather muscular and savage looking Shining Armor.

Under Chrysalis' new rule of Canterlot, both Celestia and Luna had become her personal pet, and most of the citizens were collected as broodmares and living sex toys. Given her past with Cadance and Armor, Chrysalis chose a more vindictive approach. Torturing and experimenting on Shining Armor's body, Chrysalis drove the stallion to madness, leaving him as a hulking brute with nothing but a massive cock and urges for violent sex. Chrysalis enjoyed this torturous revenge, sometimes even letting Armor break mares that were too used up to be broodmares. As for Cadance, Chrysalis experimented on the alicorn's body, but only making it a living embodiment of sexual carnality. Her breasts were enlarged and often bled milk, her nipples were stretched to the point it could take more than two cocks at once; but the process would leave the nipples too saggy and loose, resorting to them being clamped by large nipple piercings with heavy bells on them. Her pussy, uterus, mouth, and asshole was trained and modified to handle nothing short of a mature dragon, as well as the sheer load it could produce.

For the first few months, Chrysalis would have Cadance savagely raped by every changeling in her hive, then every male citizen in Canterlot, as well as all neighboring towns, and finally she has been left in the care of Shining Armor as his favorite plaything. So much large Armor had become that he only needed one large hand to wrap around Cadance's body and a large bulge swelled her flexible body as he stretched her body with each thrust; Cadance herself gurgling large quantities of cum from her earlier muzzle fuck. Chrysalis's gaze turned from the spectacle to her guests. Her eyes lit up as she saw Dusk walk towards her, her body becoming hot and aroused by the musk her sensitive nose picked off his body.

"My lovely King Dusk Shine." Chrysalis announced, rising from her throne. Her arms spread open with excitement as she approached the King. "What brings you here so unexpected to my hive?"

"I am curious how my territory is handling under your allowed rule." Dusk said, his tone was a mix of inquiry and command. A feeling of being dominated shivered through Chrysalis as she heard his voice, and felt the vibration of his sound. "I do not want to learn all you've done is petty revenge."

"Of course not." Chrysalis defended, looking back to the Princesses. "I did exactly what you allowed me, but I have scattered my forces far and wide. We can conquer any land overnight, at your command of course."

"Very good." Dusk complimented, placing his thumb and finger on Chrysalis' chin. The changeling's body quivered at Dusk's touch; a sensation that did not escape Dusk's sights. "I believe you are due a reward. But first, you are to bring me the following." Dusk simply handed Chrysalis a slip of paper. The changeling's eyes lit up with shock at what was written but never the less, Chrysalis smirked at the order.

"As you command my king." Chrysalis bowed her head. "I will have my best handle this, and will of course have them all by tomorrow." Chrysalis gestured to one of her guards and handed the slip of paper to him. The guards quickly took to the sky and out of the castle. "For now, please enjoy what my kingdom has to offer."

It was a few hours after meeting with Chrysalis that Dusk was reading in the library of his youth. Each turning of a page reminded him of his previous, weak self. If not for his love of books, he would have burned the library in a rage. Dusk's thoughts were interrupted by a knock at the door. Quickly, Dusk composed himself and turned to the door. Without responding, the doors opened, revealing Celestia. Curious what the former Princess would want, Dusk said nothing as she made her way into the library; even closing the door behind him. There was something different about Celestia than before. She was still naked, her body was however cleaned of the changeling slime, but she walked with confidence, not the signs of being broken.

"Celestia?" Dusk called to the fallen monarch. "What brings you here?"

"I came...I wanted to see you again...and I had hoped..." Celestia's words were interrupted by the raising of Dusk's finger, and ignition of his horn. Even blindfolded, Celestia could feel Dusk's sudden anger and annoyance.

"You believe being back in my old library would change me." Dusk completed Celestia's words with disgust. He then approached the alicorn, his hands grabbing at her shoulders and slamming her on the nearby table. "You really are naive. What fool would reveal themselves to be unbroken in my presence?"

"You...you can do to my body as you wish...but you can never break me." Celestia stated in defiance, but not resisting Dusk's advances. "My kingdom, my niece, my sister, all I care about have been lost, but I will never be broken."

"Very well." Dusk replied, quickly pulling his hardened cock out. "If you will not be broken, then you will be destroyed!"

Dusk plunged his cock into Celestia's pussy, the sudden tightness, followed by a growing wetness only further drove Dusk to thrust into his former teacher. Celestia did nothing. Her arms laid at her side and she made not even a gasp or grunting moan as Dusk defiled her soft pussy. Dusk almost smirked at how strong willed Celestia was; even in defeat, Celestia still held herself to a high standard and was nearly unwavering. But that would soon change if Dusk had anything to do about it.

"You are strong, my old teacher." Dusk commented, keeping his horn ignited, letting his magic gather in strength. A single hand then grasped at Celestia's throat, while the other touched at the area of her lower section where her womb would be. "But you are nothing to me."

All at once, Celestia felt the full force of Dusk's magic take hold of her body. Her senses were heightened to nearly impossible measures. Every motion of her body felt as though she was being thrown about like a doll. The faintest grip of Dusk's hand felt as though she could no longer breathe. Her ears picked up the sound of every splash and ripple her pussy was making as Dusk relentlessly fucked it. But what really was sending her body in shock was the growing warmth of Dusk's other hand placed on her womb.

"You feel that?" Dusk asked, feeling his cum filled balls churn and slowly reach their climax. "I'm enhancing your womb, when I saturate your insides with my cum, you'll become pregnant with my child." The words caused Celestia's heart to skip a beat and her pussy surprisingly became wetter and more inviting at the comment. "But when the child is born, I will tear it from you, leaving you in the deepest pit I can send you." A single tear shed from Celestia's eye from Dusk's words; a cue that Dusk was waiting for. Releasing Celestia's throat, Dusk grabbed at the blindfold. "Now look me in the eyes as I cum." Dusk tore away the cloth, forcing Celestia to stare back in horror at him. "Look your prized student in the eyes as he rapes and impregnates you!"

Celestia's eyes let loose a torrent of tears and agony as Dusk released his thick loads of cum. Her over sensitive body burned at the heat from the spunk and the pain of her womb being stuffed to the brim felt as if her whole body would burst open. But what hurt Celestia the most was the look in Dusk's eye. Nothing. No sympathy, no compassion, no mercy, and no sign that even raping his former instructor brought him any joy or satisfaction. Celestia was now simply a vessel for his heir, only to have it torn away from her and then she would be abandoned. The sensations, the emotions, the pain was too much. The color in Celestia's eyes faded as she fell into unconsciousness.

"It seems you are not so strong after all." Dusk commented, pulling himself out; his magic quickly sealing up Celestia's cunt, insuring not a single drop escaped. "You endured because you were only hurt physically...but I broke your heart."

"An excellent lesson my King!" Called a voice, belonging to Luna, from the doorway. Unlike Celestia, Luna was broken completely; her body still covered in changeling slime and her pussy still dripping cum from her last fuck session. "I am so glad you chose my sister as the one to sire your child."

"It felt appropriate." Dusk commented, then a rough thought struck him. "Luna, would you do anything I tell you?"

"Anything my king." Luna replied with a wide smile, as if she were some loyal dog. "I am your obedient bitch!"

"Sell out your loved ones, your friends, and all you care for?" Dusk asked, seeing how far Luna would go for him.

"They, like myself, are all yours to use, enjoy, and dispose of as you wish!" Luna answered correctly with pride.

"Would you kill anyone I ordered dead? Your sister? Your niece? Or even...yourself?" Dusk asked, testing Luna's loyalty and devotion. His eyes partially widened at the sight of Luna's horn gathering some magic; not enough to challenge him, but enough to take a life.

"I can end myself at your command. I am your devoted slut, who would fuck and kill at your will!" Luna answered, feeling the satisfaction Dusk was feeling from her answer.

"You are to live, for I have a task for you." Dusk said, pointing at Celestia. "You are to ensure my child is well secured and when it is born, you are to raise it."

"T-thank you my king!" Luna cheered, her heart leaping at the role she had been given. "But what of Celestia?"

"When the child is born, I will leave her fate in your hands." Dusk then stared down at the broken Princess. "I have no further use for her."

Thank you all so much for the support. But this story will have one more chapter and it will be over. I know you all are enjoying this set up, but the challenge has run its course and I am slowly losing my muse for this piece. So I will end it with grace ~~and a massive ending orgy~~.
