Morgause stood before the gleaming mirror, her eyes narrowed as she scrutinized her reflection. The candlelight danced over her sharp features, casting eerie shadows that seemed to whisper secrets into the stillness of the chamber. She reached for a glass vial filled with a thick, inky substance, her hand trembling with excitement.

Merlin, his eyes gleaming with malicious intent, approached her, his tall frame looming over her like a specter of the night. "The time has come," he murmured, his voice low and seductive. "Camelot is ours." He took the vial from her hand. The potion within was their final gambit, the culmination of months of painstaking research and dark incantations.

Morgause nodded, her thoughts racing. She had never felt more alive than in this moment, her heart pounding in anticipation of the power that was about to be theirs. "We must be swift," she hissed. "Before the court awakens."

Merlin's eyes shone with agreement as he uncorked the vial. The potion inside bubbled menacingly, and the scent of it filled the air—a noxious mix of burning herbs and something...otherworldly. "Leave no stone unturned," he said, his voice a dark whisper. "We shall take everything and everyone that matters to the Pendragons."

Morgause's eyes gleamed with malice as she thought of her enemies. Uther, Arthur and Morgana Pendragon had always been a thorn in her side. With the Great Purge, Uther had almost completely destroyed the magic world. He killed many of her loved ones. The only reason he stopped after 20 years of persecutions was the fact his daughter, Morgana, ended up being a sorceress, and, unwilling to kill her, Uther had stopped his attack on magic.

It was too little too late for Morgause. The wounds and scars were running too deep to be forgiven. She would relish watching this kingdom crumble beneath her feet.

But first, she had to claim her prize, and so had Merlin.

Merlin was a fellow sorcerer, who had also suffered deeply because of Camelot reign of terror. Together they created a family bond and promised that together they would destroy Pendragon. But during the long years fighting that cursed family, both became infatuated with Uther’s children, Arthur and Morgana.

Merlin found the blond price charming and fascinating in his knighty strength. He wanted his brightness for himself.

Morgause as well found herself unable to forget the Pendragon Princess, Morgana. Her elegance combined with her magic powers, that always fought hers to defend Camelot, made her breathtaking in Morgause’s eyes.

As much as they hated Uther, they wanted the prince and princess of Camelot for themselves more than anything. And now, they would have them.

That night they had infiltrated the castle, and managed to kill Uther, sending his soul to hell for eternal punishment. All was left was taking their rewards and the kingdom.

They made their way through the castle's shadowy corridors, the clack of their boots echoing off the cold stone walls. The silence was thick, a stark contrast to the chaos that would soon unfold.

They reached the chamber where Morgana lay, oblivious to the fate that awaited her. The door creaked open, and Morgause stepped inside, her heart beating a warrior's drum in her chest.

Merlin followed, his gaze fixed on the sleeping form of the young sorceress. He knew she was powerful and the thought filled him with a thrill of both fear and desire. He had seen what she was capable of in their brief encounters. To bend her to their will would be a triumph beyond measure.

Seeing as Morgause was finally about to get her prey, Merlin was looking forward to get his own.

Morgana stirred in her sleep, a flicker of unease crossing her features. Perhaps she sensed the dark presence that had entered her sanctuary. But it was too late. Morgause was upon her, one hand clamped firmly over her mouth, the other pinning her wrists to the bed. The girl's eyes snapped open, wide with terror as she realized what was happening.

Merlin watched with cold fascination as Morgause secured a thick, black scarf around Morgana's mouth, silencing her muffled screams. He knew the girl would fight—she had the spirit of a lioness—but the potion would ensure her compliance. He stepped closer, the potion in his hand ready to be administered.

The potion hit Morgana's tongue, and she writhed in protest, her eyes rolling back in her head. The room grew hazy as the effects took hold, and her body went limp.

Morgause released her grip, a twisted smile playing on her lips. "Welcome to your new reality," she said, her voice dripping with lust.

After removing her clothes, they bounded Morgana's wrists with leather straps attached to the bedposts and her ankles to the frame, leaving her spread-eagled and vulnerable.

Morgause didn’t hesitate and went down on her. She started to lick her intimate parts with gusto, ignoring her captive’s struggles. After getting her wet with her tongue and fingers, she retrieved a collection of devices from her bag at the foot of the bed—whips, chains, and an assortment of intricate dildos that gleamed in the candlelight. Each one had been enchanted with a spell to maximize pain and pleasure, ensuring Morgana's complete submission.

Morgana's eyes grew wide with horror as she took in her new reality. Her body was no longer her own; it was a plaything for her rival’s twisted desires. But Morgause had not yet begun her true torment.

She selected a particularly large dildo, one that would stretch the girl's limits. With a wicked laugh, she began the incantation that would activate its enchantment.

Merlin watched, his own desires stirring. He had always found Morgana's fiery spirit alluring, and the thought of breaking her filled him with a strange thrill. But he knew he had to focus on Arthur. He had plans for the boy, plans that would shape the destiny of not just Camelot, but the entire realm.

As Morgause continued her ritual, Morgana's eyes glazed over, the potion taking its toll. The room grew hot, and the air crackled with dark magic. The dildo grew warm, almost alive in Morgause's hand, and she pushed it into her captive's quivering body without hesitation. Morgana's muffled whimpers grew louder as the enchanted object began to move within her, setting a rhythm that matched the beat of her racing heart.

Merlin took one last look at Morgana, her body contorted in silent screams, before turning away. He had work to do. Arthur was his prize to claim, and he would not rest until the throne was theirs.

The castle was a labyrinth of shadows and unsuspecting souls—his to manipulate and control.

Morgause, meanwhile, reviled in her newfound power over her young rival. She knew that Morgana would be a formidable adversary if she ever regained her senses, but for now, she was a plaything, a pawn in their grand design. And as the night stretched on, Morgause's twisted games grew more and more intense, her magic weaving a web of pain and pleasure around Morgana that she could never escape.

Elsewhere in the castle, Merlin approached Arthur's chamber with a sense of purpose. The potion he had concocted was even more potent than the one used on Morgana. He knew that the boy would fight back with every ounce of strength he had, so he had to be prepared for a struggle.

He slipped inside the prince’s room, the shadows swallowing him whole. Arthur lay there, sleeping soundly, his chest rising and falling in the flickering candlelight. Merlin felt a strange mix of lust and pity as he gazed upon the youthful form, so innocent and untouched by the darkness that was about to claim him.

With a swift motion, Merlin coated a cloth in the potent elixir and pressed it over Arthur's mouth and nose. The prince awoke with a start, his eyes wide with confusion and fear. He struggled, his muscles straining against the unseen bonds that held him to the bed, but it was no use. The potion worked its way into his system, turning his limbs to water and his mind to putty.

Merlin waited patiently, his own arousal growing as he watched Arthur's fight leave him. When his body had gone slack, he began to tie him up, his hands moving with the precision of a master craftsman. He used the ancient art of shibari, wrapping rope around Arthur's wrists and ankles, creating intricate patterns that both bound and displayed the young man's body. The ropes bit into Arthur's skin, but he was too far gone to feel the pain, his thoughts a whirlwind of confusion and horror as he realized what was happening.

The wizard then proceeded to strip Arthur of his clothes, leaving him naked and exposed. He took in the sight of his prize, his gaze lingering on the his toned form, the muscles that had been honed by years of training and battle. This was the body of a warrior, destined to be king in a different reality —and now it was his to command.

Merlin's eyes fell upon Arthur's cock, already beginning to stir despite the circumstances. He knew that the potion would make him receptive to his touch, eager to please and be pleasured. With a twisted smile, he reached for his own belt, his own desires demanding attention.

The rope felt rough against Arthur's skin as Merlin bound him into a series of complex knots that left him utterly at the wizard's mercy. And as Merlin began to explore his new plaything's body, Arthur could only moan into the gag that had been secured around his head, his eyes glazed with the haze of the potion and the beginnings of an unwanted arousal.

The room was filled with the scent of sex and the sound of ropes tightening as Merlin worked, his own excitement growing with each twist and pull. He had dreamed of this moment for so long—to have Arthur beneath him, writhing in pleasure and pain, his body a canvas for Merlin's darkest desires.

Finally, the wizard was ready. He removed the gag from Arthur's mouth and whispered a single word: "Beg."

The spell took hold, and Arthur's eyes rolled back in his head as he began to plead, his voice a desperate whine that sent shivers down Merlin's spine. The prince was his, body and soul.

Merlin's hand closed around Arthur's cock, and the young man's hips bucked involuntarily. He had never felt such a powerful hand on him, never experienced such a mix of fear and need. But he was powerless to resist, his body responding to the wizard's touch as if it were the most natural thing in the world.

Merlin stroked Arthur with a firm, unyielding grip, his own erection straining against his trousers. He watched with sadistic pleasure as Arthur's body began to respond, his cock growing hard and his breaths coming in gasps.

And as the first light of dawn began to creep through the window, Merlin claimed his prize. He pushed into Arthur's tight, unprepared body, his own climax building with every thrust. The room was filled with the sounds of flesh slapping against flesh and Arthur's muffled cries of pain and pleasure.

In that moment, as the sun rose over the conquered lands of Camelot, Merlin knew he had Arthur exactly where he wanted him. The once-mighty First Knight of Camelot was now nothing more than a whimpering wreck, bound and broken beneath the wizard's skilled hands.

Arthur's eyes, though glazed with the potion's power, burned with a flicker of defiance that only served to excite Merlin further. He knew the struggle within Arthur was real—his body was a battleground of wills, a war between the darkness that sought to claim him and the last vestiges of his own identity.

Weeks later, the castle had transformed into a playground of depravity and dark magic. Merlin, now seated upon the throne, felt a thrill of power each time he looked upon the bound forms of Arthur and Morgana, his twisted creations that served as a constant reminder of his victory. He had taken the crown, but the true prize was the control he held over the two most powerful people in the realm.

Morgause had wasted no time in making herself at home in the queen's chambers. She had always coveted power, but was satisfied with leaving the throne to Merlin.

As Merlin approached her chamber, the unmistakable sounds of Morgana's muffled cries and the slap of leather against flesh reached his ears. He couldn't help but smile—his friend was a creature of habit, after all. She used to enjoy forcing pleasure and pain on every woman she fancied , even if briefly.

Merlin pushed open the heavy door to find Morgause straddling a bound Morgana, her hips moving in a rhythmic, punishing dance. The strap-on she wore was thick, and she used it to assert her dominance over her helpless captive. Morgana's eyes, filled with a mix of pain and rage, met Merlin's briefly before dropping to the floor, defeated once more.

Merlin stepped into the room, a naked Arthur in tow, a leash attached to a thick, studded collar around his neck. The boy’s body was marred with the evidence of their countless sessions, a canvas of bruises and welts that told a silent tale of his suffering. But Arthur's cock was hard, a traitor to his own mind, standing at attention.

Morgause looked up, a smirk playing on her lips as she took in the sight of her friend/brother with his new pet. "You've come to join us?" She purred, not missing a beat in her relentless assault on Morgana's body. "Your little whelp seems eager."

Merlin tugged on Arthur's leash, pulling him closer to the bed. The former price’s eyes followed, unable to look away from the scene before him.

"Indeed," Merlin said, his voice like velvet over stone. "He's learned his place quite well." He reached out and stroked Arthur's cheek. "Haven't you, my sweet?"

Arthur reluctantly nodded, his voice a hoarse whisper. "Yes, my lord."

Morgause's smirk grew wider. "Good boy," She cooed, driving the strap-on deeper into Morgana. The younger sorceress's eyes rolled back in her head, a silent scream trapped by the ball gag that filled her mouth.

Merlin stepped closer to the bed, his own desires swirling like a storm within him. He looked down at Arthur, who stared back at him with a mix of fear and longing. "Kneel," he commanded, and Arthur obeyed, his knees hitting the cold stone floor with a thud.

Morgause leaned slightly back, her own breaths coming in ragged gasps. She reached for Arthur's bound cock, her hand tight around its base. "You see, slut," She taunted Morgana, while still fucking her, her voice thick with satisfaction, "His loyalty lies where we want it to."

Merlin leaned in, his lips brushing against Arthur's ear. "You're mine," He whispered, his breath hot and heavy. "Body and soul."

Arthur's eyes squeezed shut as he nodded, his body trembling with need and fear. The leash grew taut as he fought against the urge to pull away, to resist the dark thrall that held him captive.

But resistance was futile. The potion had seen to that. And as Merlin took his place beside Morgause, the two of them ready to continue their twisted dance of dominance and submission, Arthur could only pray for the strength to survive the endless nightmare that had become his existence.

Merlin and Morgause exchanged a look of understanding.

Morgause removed herself from Morgana and sauntered over to Arthur, her eyes gleaming with malice. "Clean it," She instructed him while pointing at the strap-on.

Arthur moved his face away in disgust, but couldn’t help a pain gasp when Merlin took hold of his hair in an unforgiving grip. “Didn’t you hear her? Suck it!” He screamed.

Unable to rebel against his ‘master’, Arthur took the dildo of the strap-on in his mouth and, as Merlin had taught him, began to lick and suck it, trying not to think he was tasting his sister’s juices.

Merlin sat more comfortable on the bed as he watched his pet’s mouth being raped by his friend with a sadic smile. All the while, he fingered the still bounded Morgana.

“I can feel you’re very wet and open” He taunted the girl. “I see Morgause has treated you well”

When Morgause was satisfied with Arthur’s cleaning skills, she and Merlin secured Arthur to a chair, his body taut with tension, as he was gagged. Morgause reached into her bag of dark delights and pulled out a dildo, longer and thicker than any he had seen before. She approached Arthur with a predatory grace.

She ignored his muffled protests and pushed the dildo in him, delighted it went in smoothly…a clear sign Merlin had used him daily.

Merlin took his place at Arthur's side, his own arousal clear. He leaned down and whispered into the boy’s ear, "You will watch as I take your sister, as she gives me the child we need to rule this realm, and your body will respond."

Arthur’s eyes widened in horror.

With a flick of Morgause’s wrist, Morgana’s gag was replaced by the strap-on. The blond witch put a leg on each side of her face, straddling her. Slowly, she lowered herself, until the dildo of the strap-on was all the way in her. The phallus was pressing into Morgana’s mouth as Morgause's weight settled on her face. She could smell her as she began to grind herself against the dildo.

Merlin positioned himself between Morgana’s spread legs, his own cock thick and demanding. He took a moment to appreciate the sight of her, bound and helpless, before plunging into her with a savage growl. The girl's eyes widened in pain and fear, her muffled screams vibrating along the dildo and sending the vibrations right into Morgause, whose face was a mask of ecstasy.

Watching his sister being violated like that sent Arthur's stomach churning. He knew that if he didn't find a way out of this, if he didn't somehow regain control, they would be lost to the darkness forever.

The room was a cacophony of wet, slapping sounds as Merlin's hips met Morgana's, her body jolting with each thrust. Arthur's eyes watered from the gag, his throat burning as he tried not to choke on the leather invader. He could feel the potion's hold on him waning, his mind slowly clearing as the initial shock of his new reality set in.

As Merlin's rhythm grew more frenzied, Arthur felt a strange, unbidden response from his own body. The potion was wearing off, and with it, the compulsion to submit. He began to struggle again. His eyes met Morgana's desperate ones. He silently tried to convey a silent plea for her to hold on, to fight alongside him.

Morgana's eyes never left Arthur's, and for a brief moment, the connection between them was unbreakable. In that instant, she knew he was with her. The spark of hope grew into a flame, and she redoubled her efforts to resist, her body bucking and writhing beneath Morgause and Merlin's weight.

Merlin, lost in his own lust, didn't notice the change in the room's energy. His eyes were squeezed shut, his teeth gritted as he approached his climax. But when he opened them, he saw Arthur's gaze, clear and defiant, and he knew that the battle for their hearts and minds had only just begun.

The air grew thick with tension, the magic in the room pulsing like a living entity. Merlin knew he had to finish this, to claim his prize and secure his power. He pushed deeper into Morgana, his hand reaching down to fondle her clit with a brutal precision.

But as he reached his peak, something strange happened. The potion that had held Arthur in its thrall was suddenly broken, the spell shattering like glass. Arthur roared in fury, his body straining against his bonds as he felt a surge of strength that he hadn't known he had.

And as Merlin came, his seed spilling into Morgana's unwilling body, Arthur felt the last of the potion's hold break.

With a snarl, he bucked and thrashed, the ropes straining against his powerful muscles.

Morgause and Merlin paused, their eyes widening in shock as they realized their control had been shaken.

Merlin left Morgana and his hand went to Arthur's cock, his own climax forgotten in the face of the rebellion before him. He stroked it roughly, trying to rekindle the desire that had been so easily stoked before. "Look at her," he snarled, his voice filled with rage. "Look at how much she wants this."

But Arthur's gaze was locked on Morgana's tear-streaked face, her eyes filled with pain and anger. He saw the fire in her soul, the same fire that burned in his own heart. And with a roar that seemed to shake the very foundations of the castle, he broke free of the ropes, sending the chair clattering to the floor.

Merlin stumbled back, his cock still hard and dripping with the evidence of his conquest. "What sorcery is this?" he roared, his eyes wild with fear and fury.

Morgause, too, had stopped her depraved ministrations, her own orgasm forgotten as she stared at Arthur in shock.

Arthur stood tall, his body a testament to his newfound resolve. "The only sorcery here," he growled, "is yours. And it ends now."

The room was a blur of motion as Arthur lunged for Merlin, his fists flying. The wizard was caught off guard, his reflexes dulled by the passion that had consumed him. Arthur's fists connected with his face, sending him sprawling back onto the bed.

Morgana took advantage of the distraction, wriggling free of the ropes that bound her ankles and kicking Morgause and the dildo gag from her mouth. She spat and choked, the taste of leather and her own despair bitter on her tongue. "Arthur," she whispered, her voice hoarse from screaming.

The two siblings locked eyes, their connection stronger than the dark magic that had bound them. Together, they stood against the two monsters that had stolen their home, their lives, their very selves.

Merlin scrambled to his feet, his hands sparking with dark energy. "You think you can fight us?" he sneered. "We are the masters of this realm now."

But Arthur was not cowed. "We will fight," he said, his voice steady and sure. "We will fight until we are free, or until we are dead."

Morgause stepped closer, a vicious glint in her eye. "You dare defy us?" she spat. "We will show you the true meaning of power."

The siblings exchanged a look, one of grim determination. They had nothing left to lose but their dignity, and they were not about to let that slip away so easily. The battle had only just begun, but in that moment, they knew that no matter the cost, they would fight together to the very end.

The castle of Camelot had become a prison of the mind and body, but within the heart of its true king and queen, the flames of rebellion had been lit. And as they stood, bruised and bound, the shackles of their captors' control began to crack and crumble. The night was dark, but the dawn of their vengeance was nigh.

***

The battle had been fierce, a clash of steel and magic, the very air thick with the scent of blood and the acrid stench of dark spells. In the end, the combined might of Merlin and Morgause proved too great. Arthur lay on the cold stone, his body a canvas of pain and defeat, his soul a tempest of rage and despair.

Merlin loomed over him, a twisted smile playing across his lips. "You dare to challenge us?" he hissed, his eyes flashing with malicious triumph. "Your punishment will be eternal, my dear pet." He waved his hand, and the air around Arthur's groin grew hot, the outline of a phallic symbol appearing. "At first I wanted to spare you, and have Morgana bare my child, but now I think it’d be best for you to take all of me in you. You will be my breeding stock," Merlin declared, his voice echoing through the chamber.

The symbol grew solid, morphing into a monstrous dildo, longer and thicker than any that had been used on him before. It grew from the very stone, and with a vicious cackle, Merlin plunged it into Arthur's raw, abused body. The blonde’s screams of agony were music to their ears as the enchanted object began to pulse with dark energy, forcing Arthur into a cycle of endless pleasure and pain, as his body was being changed.

Morgana's fate was no less cruel. Morgause was even more evil than Merlin, especially when felt betrayed. She declared Morgana was to be the plaything of every twisted creature that called the castle home. Soon the room filled with goblins, demons, and other beings of the night, their eyes glowing with a hunger that was both terrifying and obscene.

Morgause looked upon her with a twisted sense of glee. "You will know the depths of our power," she whispered, "and you will serve as a constant reminder to all who dare oppose us."

The creatures closed in, their claws and tentacles reaching for her quivering form.

***

The months that followed were a waking nightmare.

Arthur's body was used and abused by Merlin's dark magic, his mind reeling from the constant assault of pleasure and pain. He was kept perpetually pregnant, his stomach swollen with the twisted fruits of their union. He would bare many children for Merlin.

A grim reminder of his defeat.
