The demon realm never slept.
From the sky of blood-red clouds to the spires of black stone jutting from the abyss, everything filled with the energy of sin—lust, greed, hunger, violence. It was the air they breathed, the ground they walked on.
In the heart of the capital, the Lust Quarter was alive with sound, scent, and raw desire.
Demons of all shapes and kinds prowled, wings brushing in the dark, tails flicking with anticipation. Every building was either a feeding house, a brothel, or a private domain for those who didn’t like to share.
Cheng Xiaoshi had been here all night.
The succubus sat in a high-backed chair at a private lounge’s balcony, legs spread lazily, sipping thick red wine from a crystalline goblet. The drink wasn’t wine at all, but a human’s soul along with their lust—sweet and bitter on his tongue. It was enough to take the edge off, but not enough to satisfy. It never was, lately.
His black-tipped wings twitched in mild irritation. He had a dozen food this week, but it felt like swallowing empty candy wrappers. The humans he’d been feeding on were too easy. They gave, they moaned, they came, and he was left unsated. Humans didn’t know how to fuck him the way he needed. Didn’t know how to touch a demon’s hunger without flinching.
Between his thighs, the smooth, plump lips of his pussy were already damp just from the thought—slick seeping slowly against the leather of his seat. Not even bother to cover it with furs or something. His clit throbbed faintly, aching to be touched, the heat simmering beneath his skin.
He needed something darker.
Something stronger.
And the only answer was to feed from his own kind. In this case, an incubus.
The door to the lounge opened. Cheng Xiaoshi walked back inside, slipping into the crowd, hips swaying with that languid rhythm that was part instinct, part calculated display.
His eyes swept the room, he wasn’t looking for just anyone. He was searching for him. There’s one incubus who caught his attention lately, the one that felt like bursting with energy.
The one that carried himself differently than the rest; while others prowled openly, dripping with hunger, this one moved quietly, cold, watching in silence. His aura wasn’t loud, but commanding and sharp like a blade.
And tonight, Cheng Xiaoshi wanted that blade turned on him. He wanted to see what that stillness broke into.
He spotted him across the room, sitting and leaning against a stone pillar. His horns smooth and sharp, his wings folded neatly against his back.
There he was. That white haired incubus. If he wasn’t wrong, his name was Lu Guang.
Cheng Xiaoshi’s lips curved into a smile, but he didn’t approach him. Instead, he sent out a strong predatory signal—the way only demons could understand. He wanted Lu Guang to feel it, to sense the way he was being stalked.
A silent command; Look at me.
The incubus shifted across the room, feeling something was preying on him with a strong urge. He turned his head and found the source immediately. Their eyes locked.
And Cheng Xiaoshi felt it like a hook. His pussy had clenched instinctively in response to that sharp look being thrown at him. This would be a good fuck, indeed. His tail twitched in excitement. He got his attention.
His feet slowly floated in the air, flying forward, and landed in front of the incubus. He tilted his head, letting a lock of black hair fall across one glowing eye, lips curling into a deliberate smile.
“Lu Guang, right?” His voice was smooth. “You’ve been watching from the shadows all week. Everyone is hunting here. What’s the matter? Too cold to join the feast?”
Lu Guang’s gaze lifted at him, but didn’t answer. Cheng Xiaoshi laughed softly, leaning in closer. His scent was thick with want, heat rolling off him, the ache between his thighs making itself known. He let his tail curl behind Lu Guang’s neck.
“I’ve been starving.” Cheng Xiaoshi whispered, low enough that only Lu Guang could hear. “Humans don’t do it anymore. They break too easily. Don’t you feel it too? How boring they are?”
Then, without shame, he straddled the incubus’ lap. His damp, bare pussy pressed against Lu Guang’s thigh. He rocked forward once, slow, purposeful, eyes never leaving him.
“I need someone who can actually bite back.” His fangs flashed when he smiled again. “Feed with me.”
The incubus tilted his head slightly, finally responding to the invite. “What can I get from you?”
The succubus chuckled. “I’ll give you everything I’ve been holding in… if you can take it.”
Cheng Xiaoshi grinded deliberately in Lu Guang’s lap, dragging his damp slit against the firm muscle. His pussy lips parted from the pressure, and the incubus growled to feel the slick on his thigh.
“See? I’m already damp for you. You can feed from me.” Cheng Xiaoshi leaned until his lips nearly brushed Lu Guang’s ear. “Come on, what are you waiting for?” He bit down on the incubus’ earlobe, sharp enough to sting, and the demonic energy between them flared like a match.
Their auras tangled, hunger snapping, feeding beginning even before they touched. Cheng Xiaoshi gasped, shuddering as his body arched. His pussy throbbed harder, dripping against Lu Guang’s thigh now. He clung tighter, needy, letting the incubus feel every ounce of lust rolling off him.
Cheng Xiaoshi continued grinding himself down against him, and when Lu Guang’s muscle pressed right against his clit, he moaned.
“Ohh—” The friction sent a jolt through him, his head tipped back. He rocket again, seeking pleasure from his clit grazing over the skin. His pussy leaked freely now, wetness smearing across Lu Guang’s thigh.
The incubus’ jaw tightened, his hand finally moved, resting against the succubus’ hip. He didn’t push him away. He didn’t pull him closer either. Just held him there, watching.
Cheng Xiaoshi moaned, needy, tail twitching behind him. “Ahh…” He ground down harder, small desperate circles that made his thighs tremble with each graze of his clit. He was shameless about it—using Lu Guang’s thigh for his own pleasure, rutting like a bitch until his breath hitched.
“You’re letting me do this.” Cheng Xiaoshi said against his neck, licking the skin there. “You could have shoved me off already. But you don’t. You want to feel me soak you through.”
The incubus didn’t answer, and Cheng Xiaoshi just rolled his hips again, slick squelching, the sound filthy in their space. He dug his nails into Lu Guang’s shoulders to steady himself, biting back another moan.
“Ahh… I could come just like this.” He gasped, his clit dragging across the same spot until it pulsed for more, heat flooding his stomach. “Grinding on you, feeding off you, making a mess all over your lap.”
Cheng Xiaoshi nibbled on Lu Guang’s lips, teasing and seducing. “Shall we move to a more private domain?”
And it didn’t take a long time until the incubus made a move into a private feeding chamber. It wasn’t small, but it wasn’t big either, lit only by braziers burning blue fire, chains hanging from the walls.
Cheng Xiaoshi yelped as Lu Guang shoved him onto the bed that was full of black feathers. He then laughed. In the blink of an eye, he was already naked, wings splayed and tail curling invitingly.
His thighs spread, baring the glistening folds of his pussy—pink and slick, the hood of his clit peeking from between the flushed lips. The scent of his arousal perfumed the air instantly.
“You really think you can feed me?” Cheng Xiaoshi teased, even though he already knew the answer, eyes gleaming. “You’re not afraid I’ll drain you dry?”
Lu Guang’s expression didn’t change. “You won’t get the chance.”
And soon, Lu Guang already hovered above him. Cheng Xiaoshi didn’t even have the chance to laugh again before Lu Guang crashed their lips together. The force knocked his head back into the bed.
The first kiss was brutal—their fangs clashing, full with the taste of lust. Cheng Xiaoshi moaned into the kiss. Lu Guang’s hand grabbed his chin to keep him still. A muffled gasp torn out from the succubus as sharp fangs scraped over his lower lip.
“Mngh—Ngh—”
Cheng Xiaoshi arched against Lu Guang’s chest, arms clung to his neck as he kissed back with equal hunger. Their tongues tangled, slick and demanding, lips grinding until the wet sounds filled the chamber. Every time Cheng Xiaoshi tried to take control, Lu Guang forced his jaw wider, sucking his tongue, biting down until he whimpered.
A sharp sting hit him as his lips finally bled. He groaned, clutching Lu Guang tighter, body shivering with the mix of pain and pleasure. He returned it, dragging his own fangs across Lu Guang’s mouth, tasting his blood too, smearing red between them as if it were just another kind of kiss.
They didn’t pull apart yet. Blood streaked down Cheng Xiaoshi’s chin. He moaned into Lu Guang’s mouth, and Lu Guang swallowed the whole sound, his grip on Cheng Xiaoshi’s jaw tightened as he forced him to take every punishing kiss.
Lu Guang pinned Cheng Xiaoshi’s wrists to the bed as he dragged his mouth down the succubus’ throat, his fangs sank into the skin, biting hard enough to bruise, tearing a muffled cry from him. The succubus’ neck was bleeding. The sharp, searing pain jolted through his body. Lu Guang licked over the wound.
“Ahh—Lu Guang—!” His wrists strained against the grip holding him down, fingers curling uselessly in the air before falling limp against the mattress.
Lu Guang didn’t let him go. He bit deeper, feeding without hesitation, his tongue lapping at the welling blood, sucking until Cheng Xiaoshi’s body jerked in overstimulated tremors. His head tilted back against the sheets, throat bared, chest heaving as his voice cracked into desperate moans.
Every swallow made Cheng Xiaoshi feel like he was being devoured whole. Blood spilled down his collarbone. “You’re drinking too much—ahh!” He choked, but the complaint turned into a strangled whine when Lu Guang’s teeth pressed flat to his throat again, dragging slowly to savor the taste.
His body burned, slick already pooling between his thighs. The moans that left his lips sound humiliatingly needy. Lu Guang pulled back, the sight of the succubus being helpless under his control only made him growl; low and hungry.
His lips trailing down the succubus’ body, blood smeared across the skin. Cheng Xiaoshi whimpered, arching up. “Please—more, I can’t—”
“Greedy.” Lu Guang muttered, pressing one knee between his legs to spread him. His hand slid down, cupping the soaked pussy, fingers rubbing against the hardened, sensitive clit.
“Ngh—Lu Guang—!”
“Pathetic.” The incubus said. “You’re this wet already.”
Lu Guang’s thumb pressed over his clit, twisting merciless until Cheng Xiaoshi writhed, sobbing out a broken sound. “D-Don’t play with it—ahh—ahh!!”
The succubus yelped as the other pinched his throbbing clit. His hips bucked up helplessly, slick seeping, soaking the incubus’ hand. His body was trembling, caught between blood loss and desire.
Lu Guang moved down, finally getting the full view of the mess between Cheng Xiaoshi’s legs—pussy flushed, glistening, folds twitching with need.
“Spread wider.”
Cheng Xiaoshi’s face burned, but he obeyed, thighs falling open. “Lu Guang, please—ahn!” He moaned as suddenly two fingers invaded his inside, spreading him open. Cheng Xiaoshi gasped, his walls clenching tight around the intrusion.
Lu Guang twisted his fingers deep, finding the spot, while his thumb returned to rub over Cheng Xiaoshi’s clit.
“Hngh—ahh—ahh!” His body squirming and bucking at the dual stimulation, but Lu Guang held him still, pinning his hips down as he worked him apart with his fingers.
Cheng Xiaoshi was whining breathlessly. His pussy throbbed, dripping around the fingers, every thrust pushing lewd sounds out of him. His voice broke into a plea. “Please—Please just fuck me—ahh!”
Lu Guang growled, pulling his fingers out finally, leaving Cheng Xiaoshi empty. The incubus’ cock heavy and flushed, the sight alone making Cheng Xiaoshi’s wetness spill further onto the bed.
He lined himself up, the thick head of his cock brushing against his drenched folds. But instead of pushing in, he rubbed and pressed the blunt tip over his clit.
Cheng Xiaoshi gasped, his whole body jolting. “Ahh—ahh—no, don’t tease!” The succubus cried out, panting in need. His thighs shaking, hips jerking in desperate invitation. Pussy visibly pulsing, clenching helplessly around nothing, needing to be filled so bad.
Lu Guang finally pushed forward just enough for the head to part the lips. “Beg properly.”
“Hngh, please fuck my cunt—fill me, use me—just stop teasing and give it to me!”
The incubus scoffed mockingly. “Are you always this slutty with those humans, too?”
Cheng Xiaoshi whined. “I-I don’t care what I look like—call me a slut, a whore—just don’t stop, I need your cock!”
And with that, Lu Guang pushed in with one merciless thrust, slamming hard and deep until Cheng Xiaoshi screamed. His eyes flew wide as he felt it—the thick head of Lu Guang’s cock punching right up into his cervix, forcing his belly to bulge obscenely with the outline of him.
The incubus smirked, tracing a finger over the bulge of his cock on that belly, showing how far he was inside. “Did I penetrate your cervix good? Or is it going past into your womb?”
Cheng Xiaoshi could only answer with a broken gasp as if his brain had stopped working from the ruthless invasion.
Their pace started with no mercy. Lu Guang forced his hips forward with harsh control. The thick head driving hard against the deepest spot over and over.
A strangled scream tore from Cheng Xiaoshi’s throat. His entire body arched off the sheets. “Lu Guang—Lu Guang, too deep!!”
“I’ll fuck you until you forget your name!” Lu Guang didn’t give him time to adjust. He pulled his hips back only to slam forward again, pounding relentlessly into his womb.
Cheng Xiaoshi screamed again, his body jerked violently with every thrust, legs trembled, toes curled up. “Ahh—ahhh! I can feel it; I feel it inside my womb—nggh!”
His nails clawing bloody streaks down Lu Guang’s back. The incubus growled loud as fresh blood flowed down his skin. He responded by slamming deeper into the womb, making the succubus let out another loud scream, tossing his head back at the force.
Cheng Xiaoshi choked, gasped at how intense the bulge moved beneath his stretched skin. Every thrust slammed right against his cervix and womb until his body was shaking and jolting violently. Lu Guang used him like he was nothing but a pathetic sex doll.
The incubus grabbed his face. “You’re just a cum-drunk little whore.” He growled, watching the bulge formed with each brutal thrust, “All you want is your womb stuffed full until you lose your mind.”
Cheng Xiaoshi whimpered, his answer was a broken, needy sob. “Nggh, yes—fill my cunt—breed my womb!”
“Good fucking slut!” Lu Guang’s thrusts grew faster, sharper, making the soaked folds squelch with every movement. “Should I fuck you until your womb break?”
The bed creaked under the force. The chamber filled with Cheng Xiaoshi’s raw, broken cries. His walls clenched desperately around the incubus’ cock, stretched wide it felt like he would split apart. He’s never been used like this.
“Lu Guang, I’m gonna—” His voice dissolved into sobbing moans, pussy convulsing wildly around the other, aching to spill over the edge. “Wanna cum—ahhh!” His walls spasming, slick finally gushed out around Lu Guang’s cock as he came with his back arching off.
But Lu Guang didn’t stop yet, his thrusts still vicious, fucking him straight through his orgasm. The feeding between them became a brutal, intoxicating loop—Lu Guang’s power flooding into Cheng Xiaoshi with every thrust, Cheng Xiaoshi’s own lust spilling back into Lu Guang.
The succubus clung desperately to him, tears of overstimulation finally streaking down his cheeks. “Lu Guang—Lu Guang, I’m gonna break!”
“Then break.” Lu Guang only fucked him harder until each thrust made Cheng Xiaoshi choke on his own breath.
“Y-You keep hitting… my womb—ahhh—can’t breathe!” His belly throbbed under the pressure, visibly rising and falling.
Until finally, for one last time, Lu Guang shoved himself as deep as he could go, making Cheng Xiaoshi scream loud enough to echo through the chamber. His body shuddered as Lu Guang came with relentless spurts into his womb—full, his walls milking the cock still buried deep in him.
After a few moments, Lu Guang pulled out, cum leaking out of Cheng Xiaoshi’s gaping, well-used pussy.
The incubus moved away, leaving the succubus lying limp. Cheng Xiaoshi’s body trembled, belly round and heavy from the thick load, overwhelmed by the sheer force of being bred. He looked messed up. Utterly ruined.
Bloody and teary.
As if the incubus wanted to brand him inside and out.
But despite that, energy bursting inside them after feeding on each other’s lust, hunger, and blood—feeling how good they were at taking each other, in a way that humans could never manage and provide.
He watched the incubus sit on the edge of the bed, the wound on his back slowly healed, although the red marks were still visible—so did his own wound.
It would always end up like this between demons.
No comfort. No tenderness. No aftercare.
The red sky of the demon realm had shifted—lighter now, though in this place “morning” was just a word.
Cheng Xiaoshi lay on his side, his wings limp and tail twitching weakly. The bite marks and everything were still visible. His pussy was red and swollen from the abuse, slick and cum still pooled inside.
The sheets beneath him were soaked with it—clear evidence of how many times he’d been bred through the night. His belly was still faintly round, every little movement making the warm weight inside shift.
Cheng Xiaoshi slowly sat up on the bed, watching Lu Guang fixing himself. The incubus soon turned to him. “Get out.”
“Can’t… Legs don’t…”
Lu Guang reached down, catching him by the chin, forcing him to look up. “You’ll walk. I want everyone to see what you look like after I’ve fucked you all night.”
Cheng Xiaoshi whimpered. Half embarrassment, half a needy thrill.
Outside, the hallway was still busy. Demons didn’t really “sleep,” so the Lust Quarter buzzed even in the early hours. The moment they stepped out, many heads turned.
The scent hit the crowd first—heavy, musky, unmistakably incubus seed mixed with succubus lust. Conversations faltered. A few demons watched with interest until their eyes glowing in their own colors.
Cheng Xiaoshi was barely holding himself up, leaning on Lu Guang’s arm. A robe was loosely tied over him, just enough to show the curve of his hips.
“Show them.” Lu Guang forced him to stand on his own.
Cheng Xiaoshi’s breath trembled, but he let the robe fall from his shoulders, baring everything; the bite marks, the swollen pussy with a slow trail of cum slid down one inner thigh, the faint curve of his belly from how deep and how much Lu Guang had stuffed him.
Gasps and murmurs rose. Cheng Xiaoshi flushed, but the humiliation only made his pussy clench, slick sipping again.
The robe was put back on, Cheng Xiaoshi walked down the main hall by himself. He could feel many eyes on him—on the way his walk was awkward from the soreness, on the bruises and bite marks along his neck and thighs, on the wet trail down his legs.
Until finally he reached the open balcony, standing there, kinda lost in thought. Thinking he probably didn’t need humans anymore, having sex with their own kind was… addicting.
But then a sudden goosebumps ran through his body as he felt the familiar intimidating aura on his back. He can feel him standing right behind. That one incubus who just ruined him last night.
Cheng Xiaoshi shuddered to feel Lu Guang’s hand sliding down his lower belly to rest just above the faintly round spot, pressing lightly.
“Remember.” Lu Guang whispering close to his ear. “This is what real breeding is.”
And Cheng Xiaoshi could only answer with a whimper.
