Harem Startup : The Demon Billionaire is on Vacation

Chapter 610 – You’re Too Powerful for Kinky Safety Now

He leaned up, still flushed, still panting a little, eyes gleaming.

”You said no work,” he whispered. ”But I didn’t agree to no dominance.”

”Lux,” she warned.

”I’m fully recovered,” he said sweetly. ”And extremely grateful.”

She tried to back up. ”Wait—”

But Lux moved.

No rope.

No restraint.

Just an incubus at full health, grinning like a bastard, and Mira sitting between his legs covered in his seeds.

”Oh no,” she muttered.

”Oh yes,” he said, already reaching for her waist.

The needles?

Still there.

But now?

They weren’t holding him.

They were holding her.

The realization hit Mira half a second too late. Lux moved like a shadow given hunger. Silent, smooth, smiling like a predator who’d just remembered exactly how fast he could run.

She blinked, her breath catching as Lux reached over to his other wrist, untied the rope like it was an inconvenient necktie, then sat up and looked at the remaining needles in his body.

And of course... he didn’t panic. Didn’t shout. Didn’t flinch. No. He just exhaled like a man settling into a warm bath after a 70-hour week, reached down, and started pulling the golden acupuncture needles from his skin one by one.

Gently.

Precisely.

Mira watched in stunned silence as he placed each one back into the velvet-lined box she’d brought. Like he was refiling taxes. Like a civilized incubus who had simply decided the therapy session was over and now it was time for dessert.

And then... then he looked up.

At her.

Still topless. Still flushed. Still sitting on her knees with cum drying on her chest and a faint tremble in her arms from one release and not enough satisfaction.

His eyes glinted.

That grin?

Wicked.

Lux crawled forward.

Slow.

Luxuriously slow.

His bare body moved across the silk sheets like he was born for this... and yeah, maybe he was. Maybe being the son of Lust and Greed really did give him some unfair bonus when it came to pacing, pressure, and absolutely devastating female pride.

Mira didn’t move.

She couldn’t move.

Her body tensed. Her breath stuck in her throat. Something in the air changed.

The usual playful energy? Gone.

What replaced it was heavier. Thicker. More primal. Like the moment in chess right before a checkmate when both sides know the game’s already over.

”Mi~ra,” Lux whispered as he reached her.

Her name slithered off his tongue like a sin in silk.

”Let’s play,” he murmured. ”Let me give you... pleasure.”

Her heart skipped.

His hands were already on her waist, warm and slow, stroking up her sides as he leaned in. She should’ve said something. Told him to stop. To wait. To remember he just recovered. That his feet were still tied. That he’d been unconscious four days ago.

But this Lux?

He felt different.

Bigger.

Darker.

More incubus than usual.

And help her, it thrilled her.

”Lux...” she whispered, breathless.

But he didn’t wait for permission.

He kissed her.

Nasty.

Dirty.

His tongue slid into her mouth like he owned the right to taste her. His fingers splayed across her bare back, drawing her closer as her qiaopao slipped further from her shoulders. She melted... damn it, she melted, because of course she did. A week of holding herself back, watching him writhe in silence, whisper half-sentences in his sleep, beg with his eyes even when his lips stayed shut.

Now it all crashed through her. Pride. Craving. The ache of missing him. The guilt of letting others touch him first. The heat of wanting to take her place again as his.

Her knees gave out and she collapsed into his lap with a moan.

He grinned into her lips. ”Let me satisfy you, Mira...”

And she did.

She surrendered.

Completely.

Let him tip her back onto the bed, let him nuzzle down her neck, his teeth grazing her collarbone like a starving man tracing the edges of a forbidden meal. Her legs parted instinctively, her breath coming in shallow gasps as she wrapped her arms around his shoulders.

Everything was right again.

His weight.

His mouth.

His dominance.

Even the mana in the air seemed to purr.

Until...

The door slammed open.

”THE ROPE!” Sira shouted.

Both of them froze.

Mira’s eyes flew open. Lux blinked mid-kiss.

Sira stood in the doorway, one hand still on the handle, her brows pulled so hard they could’ve cut through pride.

”I felt it,” she said, voice deadly calm now. ”The rope snapped.”

Her gaze locked on them.

Mira. Topless. Flushed. Beneath Lux.

Lux. Very, very naked. On top.

Sira narrowed her eyes. ”Give. Me. An. Explanation.”

Lux raised a finger casually. ”We’re having s*x.”

”I know that,” Sira deadpanned. ”I can see that.”

Lux nodded. ”Then I’ve been clear.”

She exhaled through her nose.

”The rope, Lux. The Pride seal rope. It snapped. That’s not supposed to happen.”

”I don’t know,” he said innocently. ”I just pulled like this—”

He lifted his foot to demonstrate, giving the last bit of rope on his ankle a little tug.

The rope snapped.

Clean.

Effortless.

The tension in the room tripled.

Everyone stared.

The frayed ends floated down like defeated contracts.

”...Like that,” Lux finished.

Silence.

Even the system hesitated.

[System Notification]

[Pride Seal: Disengaged]

[Binding Restriction: Fully Broken]

[Status: Lux Vaelthorn has overridden ancestral compliance restraints]

[Congratulations: You’re Too Powerful for Kinky Safety Now]

Sira walked in slowly. Very slowly.

”What. Did. You. Do.”

Lux blinked. ”I think I... grew stronger?”

”You think?” Sira snapped. ”You think?! Lux, those ropes were forged from Pride’s ancestral control law. They’re not supposed to break unless—”

”Unless my power increased significantly,” he said quietly.

That shut her up.

”But why?” Mira whispered, still beneath him, half-pinned, bare-chested and flushed with his weight on her. She was trying to keep her head clear, but her heart wouldn’t stop pounding.

Lux tilted his head slowly, gaze distant for a moment as if mentally reviewing logs in his system. ”Maybe...” he started. ”Maybe because I just killed a prince of Greed?”

Sira tensed. Mira blinked.

Lux’s eyes sharpened. ”Or maybe...”

He paused.

His breath caught for real this time. He stared at his own hands, flexing them slowly. Something was shifting. Something internal. Heavy.
