The Scarlet Depths pulsed with desire.
A realm carved into the underbelly of lust itself—where moans echoed like hymns, and the rivers ran not with water, but succubus nectar.
And in the throne of writhing flesh and chains of semen sat the final royal challenge—
Duchess Velmina
Scarlet Succubus of the Abyss.
Futa demoness.
Cock rival.
> Race: High Futa-Succubus (Royal Line)
Level: 500
Length: 16 inches of hell-forged dick
Condition to Tame: Win the Trial of Endless Sex
Must outlast her in raw stamina, edging dominance, and cock-to-cock submission play.
Caution: She WILL attempt to breed you first.
---
The air was thick with infernal musk.
Velmina stood nude before Jinwoo, her huge futa cock already semi-hard, veins pulsing with dark magic, pre leaking from the tip and trailing down her thigh like a challenge. Her body was a lewd masterpiece—hourglass hips, muscular curves, and glistening purple skin lit by floating candles.
She grinned, sharp fangs gleaming.
"You've mounted goddesses, melted virgins, and drowned monsters in cum… but this?"
She stroked her cock slowly.
"This is where your streak ends, boy. I fuck kings."
Jinwoo smirked, stepping forward, his cock already throbbing, heat radiating from it like a godforge.
"Then get on your knees and worship mine first, demon bitch."

> [TRIAL OF ENDLESS SEX: INITIATED]
Goal: Dominate Duchess Velmina through cock dueling, prostate edging, humiliation play, and forced climax
Victory: She must cum begging and broken
Penalty: MC gets reverse-bred and loses royal dominance
---
The rules were clear:
– No normal sex
– No spells
– Just two cocks
– One winner
They stood chest to chest—shaft against shaft, twitching, rubbing, leaking. The duel began with a hard grind, cockflesh slapping, pre soaking both of them.
"Big for a mortal," Velmina hissed.
"But can you last?"
---
ROUND ONE: Cock Pressure Grind
Jinwoo slammed his hips forward, pressing his cock up under hers, tip slapping against her throbbing head.
She moaned. "Nnnghh... y-your heat—!"
He grabbed her horns, yanked her close, and ground his cock against hers until both were wet with so much pre they dripped down to their thighs.
"Moaning already?" he whispered.
"Bitch, we just started."
> [Pressure Domination: +1]
---
ROUND TWO: Edging Lock
He activated Tail Bind Technique, his fox tails wrapping around her cock mid-pump, slowly stroking her while holding her at the edge.
"G-GAH—STOP—YOU'LL MAKE ME—"
He leaned in, licking the tip of her cock as her eyes rolled.
She clenched her fists. "F-FUCK—THAT'S—ILLEGAL—!"
"Not in my empire."
> [Edging Count: 5x]
[Velmina's Cum Threshold: 94%… 97%…]
---
ROUND THREE: Prostate Worship Submission Play
Jinwoo slammed her back onto the fuckthrone, legs spread, and summoned a spectral tongue made of pure EP.
The tongue slid under her cock… and plunged into her futa hole.
"AAHHHHHHHHHHHH—!!!"
She spasmed violently. Her cock pulsed.
Her back arched. Her thighs trembled.
"No one—touches me—THERE!"
"I just did. And now your royal futa ass is mine."
He fingered her prostate while grinding cocks together, moaning right into her face.
> [Domination Threshold: Exceeded]
[Futa Core Unstable… Orgasm Imminent…]
---
She tried to resist.
But her body betrayed her.
"NO—WAIT—I'M THE ONE WHO BREEDS—!!"
He slammed his cock against hers, tongues twisting, prostate throbbing—
AND SHE CAME.
---
> [FUTA CUM EXPLOSION – OVERLOAD]
Her cock erupted in thick, magical futa seed, spraying up her own belly, face, and tits—white, humiliating, and endless.
Her moans echoed across the Scarlet Depths.
Jinwoo didn't let up.
He kept grinding, fucking her with cock pressure until her second orgasm hit, and her cock twitched and drooled like a bitch in heat.
---
She collapsed.
Breathing heavy. Cock limp. Cum covering her from hair to heels.
"I-I… I've been bred… by a mortal…"
Jinwoo wiped her cheek with his thumb.
"No. By your new King."
> [Target Tamed: Duchess Velmina – Futa Succubus Lv. 500]
[Skill Unlocked: Lust Reversal – Turn futa lust back on itself]
[Title Earned: Demonbreaker – Slayer of Pride Cocks]
---
Velmina crawled to his feet, licking his cock in full submission.
"Please… use my cock hole… every day… make me your royal cumdump…"
Jinwoo turned to the harem.
"All foreign royals now kneel.
It's time to breed the next generation of world-ruling sluts."
