The Heroine is My Stepsister, and I'm her Final Boss-Chapter 129: Dare Not ( 18+)

Atlas smiled.

Not with warmth.

Not with charm.

But with the cold, methodical smirk of someone who had planned ahead and found his opponent already off-balance. The expression didn’t belong to a teenage boy—not really. It was the smile of a tactician wearing a younger skin, borrowed and disguised.

His heartbeat was loud, erratic, and his body was betraying its age, its inexperience. The heat coursing through his blood was not just from the closeness, the tension—it was hormonal, primal. But Atlas had survived the Dark Continent. He had seen minds break before bodies did. And he had rebuilt his soul from the ashes of betrayal.

This?

This was just another test of control.

His fingers twitched slightly at his side, subtle as breath. Internally, he activated the tools gifted to him long ago—tools no one in the Emerald Palace even knew he possessed.

[World Understanding: Activated.]

[Minor Hypnosis: Active.]

A brief flicker passed through Isabella’s gaze. Barely a crack, but Atlas caught it. She wasn’t fooled—not entirely—but she was unsettled. The sharp gleam in her emerald eyes wavered for a fraction of a second, like glass under strain.

’Good,’ he thought, eyes narrowing just slightly. ’It’s working.’

Her mind—brilliant, obsessive, unstable—was not so easy to sway, but it didn’t need to be fully bent. Just tilted. Just enough.

He could feel the pulse of her ego through every word she uttered. It was like facing a dragon not by scale or fire, but by pride. And pride was always the weakness.

’Technically, I cheated,’ he mused, the corner of his lip curling. ’But if you’re facing someone who poisons kings and tortures her own colleagues , cheating isn’t dishonor. It’s survival.’

The power between them wasn’t physical anymore—it was psychological. Atlas could feel her trying to pierce through the fog he was casting, trying to find the boy she once thought she could dominate. But that boy wasn’t here.

The pressure in the room thickened.

Isabella’s shoulders straightened, her voice slicing through the air. "You think I would break because of your little tricks? Because of posturing and arrogance dressed up like confidence?"

She stepped closer, and the moment stretched thin. Her words were measured, venom-laced but almost curious.

Atlas didn’t flinch. He met her eyes with steady intensity. "No," he said softly. "I think you’ll break because you already did. The moment you brought me here. The moment you wanted use me to dominate a fellow Nobel. That’s when you started playing defense."

Her breath hitched.

A beat passed.

Another.

Then—Isabella scowled, masking it with a scoff. "Delusions of grandeur. You really are full of yourself."

"Confidence and madness," he replied smoothly. "You taught me they were two sides of the same coin, didn’t you? Hell...you even showed me."

She paused.

He watched her. Studied her. The pulse in her neck was faster now. Her pupils slightly dilated. His minor hypnosis didn’t control her—it couldn’t. But it clouded the certainty. It made her doubt what she saw, made her question how much of this was real.

How much of her control was hers.

The silence between them sharpened. Not empty—charged. Like a battlefield seconds before the first arrow flies.

And then he stepped forward, not with force, but with command.

She tilted her head, feigning boredom. But her eyes betrayed her, flicking once to the sealed door behind them. The room beyond it—the weapon, the mage, the project—was her lifeline, her obsession. And now, it was in his reach.

"What exactly are you trying to prove, Aiden?" she asked at last, voice silk over steel. "Okay...you won, you lasted longer..."

"But...You think I’d cum just because you are good with your petty fingers..?" Isabella taunted, her voice dripping with mockery, her emerald eyes glinting with challenge as she leaned closer, her breath hot against his skin.

Atlas didn’t flinch, stepping forward until their faces were inches apart, his gaze burning with primal hunger. "Don’t worry, Your Highness," he growled, voice low and dangerous. "In the next ten minutes, I’ll make you cum ten times harder than you ever thought possible."

Isabella scoffed, her lips curling into a defiant smirk, but her flushed cheeks betrayed her arousal. "Oh, really?" she purred, her tone daring him to prove it. "Let’s see if you can, Aiden."

The air crackled with tension, their bodies radiating heat, each word a spark igniting the raw, insatiable desire between them.

He leaned in, close enough to smell the tension in her breath, the faint scent of myrrh still lingering from her robes.

"That the war has already started," he whispered. "And I’m already winning."

Before she could start her taunt, he pounced, a predator claiming his prey. His lips crashed against hers, fierce and unrelenting, his tongue invading her mouth with a hunger that burned through her defenses. She melted into the kiss, her body betraying her defiance, a soft moan muffled against his onslaught.

"Y-you... dare... I’m... queen..." she gasped, her words fractured as his tongue ravaged hers, each stroke a declaration of dominance. Her hands clawed at his shoulders, torn between pushing him away and pulling him closer.

He broke the kiss, his breath hot against her swollen lips. "You think I care?" he growled, voice low and dripping with menace. "After this, I’ll use every inch of your body like a slave. A fucking slave, Your Majesty. You touched the bull—now you get the horns."

Atlas’s mind churned, a storm of vengeance and raw desire. This wasn’t just about the plan anymore. Isabella, with her venomous schemes and cruel manipulations, had poisoned his life, plotted his downfall with that cunning smile. Her hateful stare had sealed it—conquer or be conquered. But deep down, he knew the truth. This wasn’t just revenge. His cock throbbed, hard as iron, screaming for release. He wanted her, craved to sate the fire she’d ignited, to claim her body and soul.

"Turn the fuck around," he bellowed, his voice a command that brooked no refusal. He gripped her hips, forcefully spinning her until her plump, tantalizing ass faced him, curves begging to be claimed.

"Don’t... you dare," she hissed, her voice laced with fury and a tremor of anticipation. But her body told a different story—her emerald eyes gleamed with unspoken want, her cheeks flushed crimson as she licked her lips.

He didn’t hesitate. With a savage tug, he tore her shimmering green gown, the fabric ripping like paper to reveal the creamy expanse of her thick thighs. She gasped, her chest pressed against the cold wall, her breath hitching. "Aiden, you’ll regret this..." she warned, but her voice faltered, thick with need, her body trembling in silent invitation.

"Regret?" he sneered, his eyes raking over her quivering form. "Your Highness, I can see it in your .....—you’ll be the one begging if I stop now."

His hands roamed her thighs, fingers sinking into her soft, marshmallow-like skin, parting her legs with deliberate intent. Her valley glistened, a river of desire dripping down her thighs, betraying her every protest. This bitch... she’s wanted this from the start, he thought, a dark chuckle escaping him. Then take it.

Without warning, he gripped his throbbing shaft, thick and pulsing with need, and plunged deep into her slick heat. The force of his thrust pinned her to the wall, her body yielding to his invasion.

"Aaahhh!" she screamed, her voice raw, primal. "So... big!" Her insides stretched, every nerve ignited as he filled her, his cock claiming every nook and cranny of her trembling core. The sensation was overwhelming, unlike anything she’d ever felt—a delicious burn that shattered her composure, her royal facade crumbling under the weight of raw, animalistic pleasure.

He didn’t relent, his hips driving into her with relentless force, each thrust a declaration of power, lust, and retribution. Her moans grew louder, desperate, her hands clawing at the wall as her body arched to meet him, chasing the ecstasy that threatened to consume them both.
