Chapter Text

The universe trembled beneath the iron will of Krypton. In every star system, in every conquered galaxy, whispers of their power spread like wildfire—unstoppable, unrelenting, inevitable. And now, the jewel of humanity, Earth, stood as the final battlefield.

For centuries, the people of Krypton had perfected war. Not out of necessity, but desire. Power was their religion, and conquest their prayer. To lead such a race required strength, cunning, and a bloodline unmatched. Kal-El and Kara Zor-El, the crowned prince and princess, heirs to Krypton’s twin thrones, embodied all these qualities.

But today, their attention was fixed on a small blue planet—Earth.

The Earth Shield hummed with electric defiance. From orbit, the translucent barrier was the only thing standing between the Kryptonian fleet and the world below. Where other planets had knelt within hours, Earth had held on for months. Humanity’s ingenuity, born of desperation, had birthed a defense that Krypton’s mightiest ships could not breach.

In the center of their command vessel, Kal-El watched the flickering shield with a smirk. His eyes—cold, calculating—glowed faintly red as he considered his options. Beside him, Kara Zor-El stood with arms crossed.

“Persistent little insects, aren’t they?” Kara’s voice dripped with disdain.

Kal’s lips curved into a humorless smile. “Every empire needs a final victory. Let them cling to hope for a moment longer. It makes the fall that much sweeter.”

Their attention turned as a Kryptonian officer stepped forward. “The Luthor ship has been captured, Your Highnesses. The Earth scientists, Lex and Lena Luthor, are aboard.”

Kal’s brows rose in interest. The Luthors. Even among their enemies, their names carried weight. The brilliant siblings who had dared to challenge the Kryptonian fleet, who had created the shield that barred their conquest.

“Bring them,” Kal ordered.

The Luthor siblings were dragged into the throne chamber aboard the Kryptonian warship. The room was vast and cavernous, lined with banners bearing the crest of the House of El. At the far end, Kal and Kara sat atop twin thrones of dark metal, the weight of their presence suffocating.

Lex walked forward with measured steps, his head held high despite the guards flanking him. His emerald eyes, sharp and defiant, scanned the room with practiced precision. Beside him, Lena clutched her coat tightly, her knuckles white as she trembled under the intensity of the Kryptonian gaze.

Kal leaned back, one arm resting on the armrest as he studied his captives. “The famous Luthor siblings,” he drawled, his voice deep and mocking. “Creators of the Earth Shield. I should be impressed, but instead, I find myself… irritated.”

“Good,” Lex replied coolly. “That means it’s working.”

Kara’s gaze snapped to him with a hint of fury. No one spoke to Kryptonian royalty that way and lived. Kal only chuckled darkly. “You’re brave, human. But bravery is rarely rewarded.”

He stood, his towering form casting a long shadow as he approached the siblings. Lena flinched, but Lex held his ground.

“You know the shield won’t last,” Kal said softly, his tone almost conversational. “Your energy supply is finite. Turn it off. Surrender, and I will grant you mercy.”

“Mercy?” Lena whispered, her voice small.

Kal smiled down at her, almost kindly. “Yes. You and your brother can govern Earth as our loyal viceroys. Convince the rebels to stand down, and your world will be spared annihilation.”

There was silence. The words hung heavy in the air, a false promise of salvation.

Lena’s lip quivered. She glanced at Lex, whose jaw remained tight, his gaze fixed on Kal-El with a mixture of hatred and pride.

“No,” Lex said, his voice cutting through the silence like steel.

Kal tilted his head. “No?”

“We’ll never betray Earth.”

The room seemed to darken. Kal’s smile faded, and a faint glow began to burn in his eyes—red, dangerous. For a long moment, he simply stared at Lex, as though considering whether to incinerate him on the spot.

Then he laughed. It was a deep, cruel sound that echoed through the chamber. “I should kill you both,” he said, his tone still light, though his eyes were anything but. “But that would be too easy. Too kind.”

He turned to Kara, who had been watching silently, a cruel smile tugging at her lips.

“We’ve worked hard for this war, haven’t we, cousin?” Kal said, a smirk returning to his face. “How about we indulge ourselves? Lady first.”

Kara’s gaze slid back to the siblings. Slowly, she walked toward them, her boots clicking against the cold floor. Lex tensed, instinctively stepping in front of Lena, but Kara ignored him entirely.

Instead, she stopped before Lena, towering over her smaller frame. Lena’s breath caught as Kara’s gloved hand reached out and brushed against her chin, tilting her face up.

“I’ll take this one,” Kara said smoothly, her tone laced with amusement. Before Lena could react, Kara lifted her effortlessly into her arms, holding her bridal style.

Lena gasped, her hands instinctively clutching at Kara’s shoulders. “Put me down!”

Kara only smirked. “I don’t think so.”

Lex lunged forward. “Lena!”

Kal’s arm shot out, blocking him with a brutal shove. Lex stumbled back, seething as Kal grabbed him by the collar.

“Don’t worry,” Kal murmured, his voice close to Lex’s ear. “You’re coming with me.”

Lex froze, his body rigid with fury and defiance. He glared at Kal, who returned the look with a smug smile.

“Take them to our chambers,” Kal ordered.

The doors to Kara’s chamber slid shut with a hiss, sealing Lena inside. The room was vast and alien, its metallic walls etched with Kryptonian symbols that pulsed faintly with energy. At its center stood a low, circular platform draped with crimson silks—a bed fit for a warrior-princess.

Kara set Lena down on her feet, her arms releasing the trembling human with surprising gentleness. Lena stumbled slightly, but before she could move, Kara stepped closer, her imposing form towering over her.

“Take a look around,” Kara said, her voice smooth and commanding. “This is your new home, little human.”

Lena’s breath hitched as she clutched her arms around herself, her eyes darting around the chamber. “Please… I don’t belong here,” she whispered, her voice trembling.

Kara tilted her head, amused. “Oh, you belong to me now. The sooner you accept that, the easier this will be.”

“I-I’m just a scientist,” Lena stammered, her voice quivering. Tears brimmed in her green eyes as she clutched her chest. “I’m not strong like my brother. I can’t… I can’t fight you.”

Kara smirked, taking another step forward. “Good. Fighting would only make this unpleasant.”

Lena let out a soft sob, her knees buckling as she sank to the floor. “Please… don’t hurt me.”

Kara crouched before her, reaching out to tilt Lena’s chin upward. Her gloved fingers were firm but not harsh as they guided Lena’s tear-streaked face to meet her gaze.

“I don’t need to hurt you,” Kara said, her tone almost gentle. “I only need you to obey.”

Lena bit her lip, trembling. “If… if I do… will you spare me?”

Kara chuckled, the sound low and velvety. “Spare you? Oh, little one, I intend to keep you.” Her hand slipped from Lena’s chin, trailing down to her shoulder. “You could have a place at my side. As my concubine, you’d be protected. Cared for. Isn’t that better than struggling in vain?”

Lena was trembling as Kara rose to her feet, her imposing figure illuminated by the faint glow of the Kryptonian symbols. Without a word, Kara removed her armor, piece by piece, revealing her sculpted, powerful body beneath. Lena’s breath caught as her eyes flickered downward, spotting the distinct feature Kryptonian females possessed—a trait that set them apart from human women.

She forced herself to gasp, her hands flying to her mouth in feigned innocence. “I—I’ve never… I’m a…”

Kara’s smirk deepened. “A virgin? How quaint.” She leaned closer, her voice a whisper that sent shivers down Lena’s spine. “Don’t worry. I’ll be gentle… this time.”

Kara’s eyes gleamed with triumph as she lifted Lena effortlessly, carrying her to the bed. The chamber was filled with the sound of silks shifting as Kara laid Lena down. 

Lena’s tears spilled over, her shoulders shaking as she cried softly. “Please…”

“Don’t cry,” Kara murmured, brushing her lips lightly against Lena’s neck. “You’ll enjoy this soon enough.”

Across the warship, Lex was thrown into the center of Kal’s chambers. The door sealed behind him with a hiss, leaving him alone with the prince of Krypton. Lex rose slowly, brushing off his coat with deliberate calmness despite the heat of Kal’s gaze boring into him.

“Is this the part where you expect me to grovel?” Lex asked, his voice sharp and unyielding. “Because you’ll be disappointed.”

Kal chuckled, low and dark, as he stalked toward him. “Groveling would be beneath you, wouldn’t it, Luthor?” He stopped mere inches from Lex, his towering form casting a shadow over the human. “No, I think you’d rather fight. Even if you know you can’t win.”

Lex tilted his head, meeting Kal’s eyes with a smirk. “You’d be surprised how often I win against the odds.”

Kal’s amusement faded, replaced by something darker. Without warning, he grabbed Lex by the collar, slamming him against the wall. Lex grunted in pain but didn’t flinch, his smirk only widening.

“You’re lucky I find you fascinating,” Kal murmured, his voice low and dangerous. “Otherwise, I’d have broken you in half by now.”

“And yet here you are, talking instead of acting,” Lex shot back, his tone venomous. “What’s the matter, Kal? Afraid of a human outsmarting you?”

The air grew heavy, charged with tension. Kal’s eyes glowed red, his grip tightening as he pressed closer. “You talk too much,” he growled.

“Then shut me up,” Lex hissed, his lips curling into a challenge.

Kal’s patience snapped. He crashed his lips against Lex’s in a brutal kiss, all teeth and dominance. Lex responded just as fiercely, biting down hard enough to draw blood. This only fueled Kal’s anger as he shoved Lex onto the nearby bed, pinning him down with inhuman strength.

Lex glared up at him, his defiance burning brighter than ever. “Is this all you’ve got?” he taunted, even as his chest heaved with exertion.

Kal growled, his hands tearing at Lex’s clothes with little care for preservation. “You’ll regret those words,” he promised.

Lex laughed, a sharp, bitter sound. “Try me.”

What followed was a clash of wills as much as bodies. Kal claimed Lex with an intensity that bordered on violence, his movements fueled by frustration and fascination. Lex refused to yield, meeting every advance with his own brand of defiance. Even as Kal’s body overwhelmed him, even as his strength left bruises and his heat burned, Lex’s mind remained sharp, calculating, and unwavering.

When Kal finally reached his peak, his release was a searing mark of dominance, his essence claiming Lex in a way that was both humiliating and strangely empowering. Kal leaned over him, his breath hot against Lex’s ear. “You belong to me now,” he said, his voice rough and certain.
