Harem Startup : The Demon Billionaire is on Vacation

Chapter 771 – Instant Coffee

His synapses were swimming in afterglow fog. Thoughts came like drunk toddlers. His internal math processor had taken the day off.

He blinked again.

Oh yeah.

He needed coffee.

He needed marriage-level coffee.

He stumbled off the bed, nearly tripping over Mira’s tail, cursed quietly, avoided stepping on one of Rava’s tentacles, and made his way toward the counter like an ancient demon returning from war.

His steps weren’t steady.

He looked like a newborn foal learning how knees worked.

His wings dropped.

His tail dragged.

His hair was a disaster.

But he made it.

He reached the counter.

He grabbed the first packet he saw.

Instant coffee.

A mortal sin in itself.

He did not care.

This was an emergency case.

He ripped it open with his teeth, dumped it into a mug, added hot water from the kettle without checking if it was clean, stirred it with a pen he found, and drank.

It tasted like burnt dirt filtered through depression.

He swallowed anyway.

His eyelid twitched once.

He waited.

Nothing.

He drank again.

Still nothing.

He placed the mug down, stared at it like it had personally betrayed him.

His brain tried to reboot.

Failed.

Tried again.

Static.

He needed stronger coffee.

Or a wife that could make him coffee.

Possibly both.

Behind him, six women slept like the dead.

Lux stood there in his half-drunken post-lust daze, mug in hand, naked, marked, aura flickering weakly, trying to remember how numbers worked.

Responsibility was clawing its way back in.

Slowly.

Painfully.

He sighed.

Yeah.

He really needed marriage-level coffee.

He took another sip, burnt dirt and despair, and forced his brain to restart like a cursed mortal laptop.

"System," he muttered, rubbing at his temples, "what... exactly happened last night? I mean the effects."

A pause.

Then the familiar flicker of text shimmered across his vision.

[Processing...]

Lux waited.

He immediately regretted asking.

[First: you leveled up.]

"Good," he whispered to himself. "Good. Maybe the pain in my soul was worth it."

The system continued.

Lux choked.

Not on lust.

Not on shame.

On instant coffee.

He coughed so hard he almost woke Mira on the floor.

"Level—"

He tried again.

"Forty levels? FORTY LEVELS?! In one night?!"

Lux stared at the floating numbers like they were giving him trauma flashbacks.

The system elaborated.

[This was the first time you combined your Greed Sin with your Lust Sin. You also let Lust completely off its leash. The synergy reward is enormous.]

Lux closed his eyes slowly, remembering flashes... 𝒇𝓻𝓮𝓮𝙬𝙚𝒃𝒏𝓸𝙫𝒆𝙡.𝓬𝓸𝒎

Yeah.

That tracked.

The system wasn’t done.

[Additionally, you have unlocked two new Sin-Fusion skills.]

Lux’s grip tightened on the mug.

He knew that tone.

It was the "congratulations, here is a power that will make the celestials pull their hair out" tone.

The first window appeared:

[Abyssal Court of Desire]

[Spreads a crimson shadow domain across the battlefield. From it emerge shadow succubi and incubi, predatory manifestations of Lust. They swarm enemies, weaken their will, and drag the vulnerable into darkness to be torn apart. Those who resist suffer slowed movement and relentless assault.]

Lux froze.

Actually froze.

His tail stopped moving mid-swish.

The system continued mercilessly.

[Velvet Marionette Dominion]

[Releases invisible threads of Lust-infused energy that attach to nearby targets. Once connected, he can disrupt movements, distort emotions, and briefly override motor control like a puppeteer. The longer the link persists, the stronger the control becomes. Weakened opponents can be fully manipulated for a short duration.]

Lux didn’t move.

His brain didn’t move.

Only his eyelid twitched.

The system chimed softly, like a passive-aggressive accountant with a grudge.

[Please balance both sins better next time. You usually suppress Lust. Extremely unhealthy. Also—]

Lux braced himself.

[No incubus should stay a virgin for 200 years. That is classified as a developmental failure.]

His soul left his body.

It actually floated six inches above him before snapping back in.

’Please don’t remind me,’ he thought, mentally collapsing. ’I had work. I am a responsible demon.’

The system responded instantly.

[’Responsible.’ Sir, you nearly died of chastity.]

Lux groaned into his coffee.

"I WAS BUSY."

[You were a 200 year old virgin, Sir.]

He slapped a hand over his face.

If the girls woke up, he would die on the spot.

The system delivered its final blow.

[Next time, please allow yourself regular Lust release. Greed-only lifestyle unsustainable. You are built for both.]

Lux lowered the mug.

Stared blankly at nothing.

His hair was a disaster.

His wings dropped.

His tail flopped behind him in defeat.

His brain answered 1 + 1 = banana.

He whispered at the counter.

"...I need espresso."

Behind him, six women slept like beautiful corpses after a natural disaster named Lux Vaelthorn.

He had leveled forty times.

Unlocked eldritch Lust dominion skills.

Damaged a bed worth 6000 hell coins.

And nearly died of horniness.

Lux stood there for a moment in existential silence, then exhaled like a demon who had survived both a natural disaster and causing one.

He looked at the floor.

Looked at the ruined sheets.

Looked at himself.

...Nope.

He was not doing this naked.

He found his night robe on the ground.

Or what remained of it.

It was ripped at the sleeves.

Torn at the hem.

Claw marks where Sira had dragged him.

Tentacle suction marks stamped across the fabric like a kraken souvenir.

Lux stared.

"...Fine."

He put it on.

The robe hung crookedly around his torso, barely covering the essentials, but he no longer had the mental capacity or emotional bandwidth to care. He tied the belt once, ignored the gap exposing half his hip, and trudged toward the door.

He didn’t walk.

He dragged himself.

Like an undead.

No aura.

No pride.

Just a man whose soul and stamina bar had been wrung dry and tossed out the window.
