Harem Startup : The Demon Billionaire is on Vacation

Chapter 13 – Marked by Greed, Bound by Pleasure (18+)

Lux made sure to take her three more times, each one rougher, deeper, and more possessive than the last.

Not because he had to.

But because he couldn’t stop.

The moment her breath hitched and her back arched the first time beneath him, something primal—something infernal—clicked loose inside him. Something that had been bound in contracts, locked in boardroom smirks, and buried under layers of fake charm and polite sin for the last two hundred years.

It wasn’t just Naomi’s warmth or her sounds or the way her fingers trembled against his shoulders like she was holding onto lightning. It was the realization—raw and crashing—that this wasn’t a deal. Not a negotiation. Not another infernal trade masked as pillow talk.

This was real.

No red-tape.

No paperwork.

No price tags.

Just sweat. Skin. And the terrifying joy of not holding back.

Every time he moved, he left heat behind—like his body was branding hers with soft, lingering trails of molten gold. The bed creaked, the marble shivered, the velvet curtains fluttered despite no breeze. Her moans tangled with the distant hum of the city below, and somewhere in the Sovereign Grand, a chandelier might’ve cracked.

Lux didn’t care.

He didn’t think about the noise. Or that his tail, wings, and horns were out in full glorious display. He only thought about her.

How her skin tasted—like rich cream and midnight promises.

How her thighs clenched around him with a force that made his spine shudder.

How her heartbeat synced to his, steady and panicked and begging for more.

It was chaos.

Controlled.

Slow-burned.

Then wild again.

Like they were fighting and falling all at once.

And the best part?

She wanted it. She wanted him.

Naomi had given herself without coercion. Without manipulation. She said yes with her body, with her gasps, with the way she whispered his name like a spell each time he pushed her over that edge.

It was sacred.

And absolutely corrupt.

A perfect paradox.

Lux bit back a groan as he claimed her again, rougher this time. Not because she was fragile, but because she wasn’t.

Naomi didn’t break—she clung, she matched, she moved with him like they were two puzzle pieces finally clicking into place after centuries of being shoved into the wrong boxes.

And she felt so good.

Her breath against his throat. Her fingernails in his back. The slight burn of friction, mixed with the dripping warmth between them—everything. It short-circuited him. Each motion carved a new ache, a new obsession. His hips slammed into her like he was trying to bury something deeper than lust.

A need.

A desperation.

A craving two centuries in the making.

Because yeah—this was his first too.

Everyone assumed that being a half-incubus meant he’d been around. That he’d seduced mortals, demons, godlings. That he’d had endless nights of pleasure soaked in wine and sin and screams. But truth was... Lux had never let it get past flirting. A kiss here. A heavy glance there. A little bit of touch. Just enough to tip negotiations in his favor. Just enough to get the signature or settle the agreements.

Hell’s finance department wasn’t the kind of place that bred romance or real connection. It bred burnout. Despair. Beige-colored trauma.

A hell inside hell.

Even the seduction was just another form of negotiation—another tool in the arsenal. A way to throw off judgment, make contracts sound better than they were. There was no heart in it. No soul. Just tired demons in thousand-dollar suits whispering sweet nothings while mentally calculating interest rates.

They all looked alive.

None of them were.

They were dead inside.

The dead inside the land of the dead. Hell.

And Lux had been just like them.

Efficient. Detached. Dangerous.

Until now.

Now, he was a mess of sweat and shadows and thundering heartbeats.

Now, he was letting his instincts run wild—grinding into Naomi like she was the only thing tethering him to this world. And maybe she was.

Because this wasn’t just physical. Not really. Not anymore.

This was his first true investment.

And he was all in.

Naomi’s voice cracked around a cry, and he caught it in his mouth like it was sacred. His pace stuttered. Then redoubled. He could feel her inside. Her delicate flesh. How they tightened around his erection and massaged it. His grip tightened on her hips. He pushed in so deep she gasped and trembled beneath him, and he felt it—that moment when she completely let go.

Just trust.

Just him.

And Lux?

He shattered right after her.

His seed erupted deep inside her. His vision sharpened with a flash of heat, not blurred. The world didn’t tilt—he owned it. Wings unfurled and wrapped around her, not in weakness, but in claim. A cage. A sanctuary.

Lux’s heart thudded in his chest.

Unsteady. Fast. Almost... mortal.

But it was the smile tugging at the corner of his lips that scared him the most.

Because this didn’t feel like a one-time event.

Didn’t feel like a fling.

Didn’t feel like a bonus to a new Chapter of his vacation.

No. This felt like a beginning.

And deep down, Lux knew—he hadn’t just made love to Naomi. He’d marked her.

Not in some infernal ritual or with a demonic pact.

But with every breath. Every thrust. Every whispered into her skin.

She was his now.

And worse?

He might be hers too.

Naomi huffed into the pillow, her breath still uneven, her entire body feeling like it had been tenderized by a demon-shaped steamroller. Her hair clung to her neck, cheeks flushed, body slick with heat... and not all of it hers. She was sprawled across the silky hotel sheets, one leg bent, the other dangling limply off the edge of the mattress, utterly spent. Completely ruined.

Lux’s seed still clung to her thighs.

Warm. Sticky. Claiming.
