Plap. Plap. Plap.
The wet, obscene sound of flesh meeting flesh filled the dimly lit chamber.
A thick sheen of sweat and oil coated grayfia Lucifuge's impossibly round ass as it rose and fell in perfect, punishing strokes.
Each downward slam buried Leo to the hilt, forcing a fresh, broken moan from her throat.
"Leo…! Ahh, Leo…!!"
Her silver hair, usually pinned in flawless elegance, now hung in damp, wild strands across her flushed back.
The former ultimate queen maid, prim, cold, untouchable, looked nothing like her reputation tonight.
Her nails dug into the sheets, knuckles white, spine arched so deeply it looked painful.
Yet every time Leo's palm cracked against the jiggling flesh of her ass, her inner walls clenched harder around him in shameless gratitude.
Leo exhaled through his nose, sweat sliding down the sharp line of his jaw.
One large hand clamped possessively on her waist while the other delivered another controlled, ringing slap.
The ripple traveled up her back like a shockwave.
'Still so tight even after hours,' he thought, almost clinically. 'Guess devil stamina has limits when you're being fucked like this.'
He rolled his hips once, slow, deliberate, grinding deep enough to make her sob his name again.
Grayfia's whole body shuddered, thighs trembling violently.
He could feel how close she was. Again.
But he wasn't ready to let her tip over. Not yet.
, , ,
Three days earlier.
"What?!"
Leo's voice cracked louder than he intended.
Sirzech's Lucifer stood across from him in the private study, crimson eyes calm, almost gentle.
The atmosphere should have been relaxed, three old war comrades sharing expensive wine, but the words that had just left the Crimson Satan's mouth made the air feel twenty degrees colder.
"I want you to impregnate my wife, Leo."
Leo stared, waiting for the punchline. It never came.
grayfia stood silently near the bookshelf, posture perfect, expression blank, like a statue carved from ice.
She didn't even blink at her husband's request.
Leo dragged a hand down his face. 'Of course. Of fucking course.'
He had arrived in this world decades ago via the least glamorous isekai method possible:
dying mid-episode in a plane crash while hate-watching High School DxD on a cracked tablet.
Woke up as a nameless low-class devil right as the civil war kicked off.
No system. No cheat skill. Just Wikipedia scraps and grim determination.
He clawed his way up. Guerrilla tactics. Earth knowledge turned into devastating traps.
Poison formulas no one in the Underworld had ever seen.
By the end he had single-handedly collapsed the entire western front, earning the title "Western Liberator" even though everyone knew Sirzech's was the face of victory after he stormed the Lucifuge stronghold.
Still, the contribution had been enough.
Satan-class power. A new family name. A sprawling estate.
Women throwing themselves at him from every noble house.
He refused them all.
Not out of chastity. Out of paranoia.
He remembered fragments from the wiki: ExE. Machine Gods.
One of them had casually one-shot Great Red like swatting a fly.
Twenty years, maybe less now, and the apocalypse would knock politely on the door.
Every year his progress slowed. Talent plateaued. Advancement costs decades instead of months. He was running out of time.
And then, two weeks ago, during a drunken "for old times' sake" gathering, Ajuka Beelzebub, half curious, half bored, had cast a diagnostic spell on Leo "just to see".
The results were… abnormal.
Human fertility retained. Not diluted by devil longevity and low birth rates.
Roughly fifty-thousand times higher than the average pure-blood devil.
Ajuka and Sizrechs had looked at each other like they'd just found the Philosopher's Stone.
And now here they were.
Sirzechs stepped closer and laid a hand on Leo's shoulder. The grip was light. Pleading.
"Please, Leo. We've tried everything. Spells, rituals, even forbidden magic. Nothing. But you…"
He trailed off. The implication hung heavy.
Leo's gaze slid sideways to grayfia.
She still hadn't moved. Hadn't spoken. Hadn't even looked ashamed.
'I hate this woman,' he reminded himself for the hundredth time.
'I hate all of them. Shallow. Power-hungry. Obsessed with strength and status. Every last heroine in this goddamn story.'
He had promised himself years ago: no entanglements. No falling for the trope-girls. No becoming Issei 2.0.
And yet.
He met Sirzechs' eyes again.
"Fine," he said quietly. "But I have one condition."
Sirzechs' shoulders sagged in visible relief. "Name it."
"I want unrestricted access to every family grimoire the Lucifer and Lucifuge houses possess.
Every spell. Every forbidden technique. Every last page.
And I will swear on my honour that no one else will know them."
A long silence.
Sirzechs glanced once at his wife, then back at Leo.
"…Done."
He turned to grayfia.
"Follow his orders completely. Please him however he wishes. I'll come for you tomorrow morning."
grayfia inclined her head. "Yes, my lord."
Sirzechs left without another word.
The door clicked shut.
Leo dropped back into the armchair, picked up his novel, and flipped it open.
He was determined to ignore the silver-haired woman now standing in his private quarters like she belonged there.
A minute passed.
Then two.
Then,
A soft rustle of fabric.
He lowered the book just enough to see her standing directly in front of him, skirts already lifted to her waist.
Black lace panties. Thighs pressed together. Face still perfectly composed.
"Master," she said, voice low and formal. "Please impregnate me."
Leo stared at her for three full heartbeats.
Then he snorted.
"Are you actually a former noble? Did they teach you nothing about subtlety back in that frozen manor of yours?"
He waved a lazy hand. "Put your skirt down. We're not starting until tonight."
Her jaw tightened almost imperceptibly.
"…As you wish, Master. Then what should I do in the meantime?"
"Clean something. Organize something. Disappear. I don't care."
He lifted the book again.
She left the room without protest.
He managed three pages before the scent hit him.
Jasmine. Gunpowder. Raw demonic power.
Leo slammed the book shut.
"Leviathan," he barked, aura flaring to peak Satan-class in an instant.
"This is the last fucking time you sneak onto my property!"
A cheerful giggle echoed from the rafters.
"Why is Leo-chan so grumpy today~? Do you need big sis to cheer you up?"
Leo pinched the bridge of his nose.
'Kill her or ignore her. Kill her or ignore her.'
In the end he slumped back and turned the page.
"This world is insane," he muttered, voice flat.
Behind him, grayfia re-entered the room carrying a silver tray of tea, silent, graceful, eyes lowered.
She set it down beside him without a word.
Her fingers brushed his wrist for half a second longer than necessary.
Leo didn't react.
But his grip on the book tightened.
Tonight was going to be long.
And very, very loud.
