Shell Experiment 3
From the Quantum Trap of a demon hunter, I could tell it had activated. With enough power to imprison a demon king like Beelzebub, blocking mental attacks was probably a given. That arrogant demon bitch had tried hitting me with a mental assault. What the hell are you, demon bitch... what's your real identity?
When I opened my eyes, she was still straddling me. Woman on top, cowgirl position. The demon possessing Choi Seo-ah's body had her hands planted on my chest, grinding her hips against me.

Her eyes half-lidded, pierced tongue flicking out like she was stabbing the air. She wore a triumphant smile, as if she'd conquered me.
"Now you're mine... your soul... your body... all of it."
Virgin pussy, virgin asshole, virgin throat pussy—with those piercings as her bizarre weapons of attack, she'd come at me. I'd nearly fallen for it beautifully. If I hadn't been a demon hunter?
Just thinking about it sent shivers down my spine. That turned into rage. Choi Seo-ah's eyes had turned pitch black, and a creepy smile hung on her lips. As my mind cleared, I realized the demon bitch was speaking directly, bypassing Choi Seo-ah's hippocampus and cerebellum. Choi Seo-ah normally spoke in that heavy Busan dialect. But the one shaking her hips on top of me right now wasn't using a trace of it.
She wasn't using Choi Seo-ah's brain to move.
But since she was using Choi Seo-ah's body... you won't withstand my counterattack.
"You're awake, Master," her voice echoed like it came from a gloomy cave. Mocking, derisive tones. I could still feel her pussy clenching around my cock. The grip was perfect.
"Fuckin' bitch."
My curse made her pussy clamp down hard. At the same time, I shot my arm out and seized her throat. I bucked my hips, flipping her onto the floor, and mounted her in a messy tangle. Her vaginal walls were still squeezing my cock.
"Ahhn~ What's wrong, Master? I'm your cock sleeve."
Before she could finish, both my hands wrapped around her neck. Fury and lust blazed inside me like fire.
"Trying a mental attack? You must be fucking suicidal."
Her eyes wavered. For the first time, bewilderment flashed across her face.
"How... how is this...?"
She twisted in my grip.
"Your mind control doesn't work on me. And that puny body of yours putting up any strength?"
I shoved her back onto the bed, pinning her wrists with one hand above her head. Interlocked fingers, she couldn't budge.
"Eek?"
She tried to move but was pinned by my single hand. Choi Seo-ah's body had superhuman strength. But it couldn't match a demon hunter's awakened power.
"Let go~ You like it rough, huh~?"
Her voice tried to sound casual and relaxed, but her pupils shook violently. My cock was still rock-hard, pounding her cervix. Every time the cold piercing touched my glans, waves of shocking pleasure poured through me.
"How...? No way?"
I thrust deep inside her in one go. A real scream burst from her lips—not the controlled, calculated moan from before, but genuine shock.
"Kreeeek?"
Her vaginal walls embraced me. Her insides still felt supernatural. But now, I had control.
"How... my power...?"
Her black eyes filled with confusion.
"Your power can't dominate me. You're just a parasite borrowing Choi Seo-ah's body."
My hips started moving fiercely. Deep, hard thrusts into her. Her body reacted inhumanly—walls wrapping, sucking, squeezing my cock.
"Aaaah! This... impossible... a human this strong?"
She writhed, but couldn't escape my grip. Her legs wrapped around my waist like resistance, but only pulled me deeper.
"The barbell... piercing... catching... ugh!"
Every hit to her cervix entrance, the piercing there teased the boundary of pleasure and pain. I could see her eyes rolling back.
"You bitch. All you can control is Choi Seo-ah's body. My mind's beyond you."
Her mouth gaped to scream, but my lips sealed it. I shoved my tongue in, tangling with hers. Her tongue piercing grazed mine. My hand shot to her breast, squeezing. Her hard nipple pressed into my palm. Her body arched like a bow.
"Mmmph!"
Her moan flowed into my mouth. No longer controlled—fear? Rage? Pleasure? Indistinguishable, but she no longer dominated.
Choi Seo-ah's body had its dopamine reward system fully wired now. A flesh prioritizing pleasure.
I broke the kiss and went for her neck, sucking hard like she'd done to me. Hard enough for a hickey.
"Kruuuh... no... this can't..."
Her words cut off. My hand found her clit, rubbing. The barbell piercing there brushed my fingers.
"Aaaah!"
Intense stimulation lifted her hips off the bed. I seized the moment, thrusting deeper. Her walls spasmed wildly.
"See? Your body's reacting to me. Orgasm's enough to turn a woman into a fallen slut."
"No... this is... this girl's body... uuuuh!"
Despite her denial, her body was honest. Juices soaked our junction. Her hips bucked unconsciously to my rhythm.
I sat up, hoisting her legs over my shoulders. Penetrating from a deeper angle. I'd already found her G-spot. My glans targeted it relentlessly.
Her eyes flew wide. Terror and ecstasy mixed.
"No... not that... deep... too deep!"
Her voice cracked. No more calm control.
Her insides clenched my cock in spasms.
"I'll conquer every hole in your body."
My hand went to her ass. One finger pushed in. Just like she'd done to me. Already slick, it slid easily.
"Uwaaaah!"
Stimulated in both holes, her body shook violently. Her nails raked my back. Sharp pain hit, but it only excited me more.
"All the pain you gave me, I'll return it."
I ramped up speed, pounding harder. The bed creaked. The room filled with slapping flesh, wet sounds, her moans.
"Haa... haa... stop... if you..."
Her breaths came ragged. Choi Seo-ah's breasts heaved. I latched on, sucking her nipple. Finger delved deeper into her ass.
"Uuuugh!"
Suddenly, her body went rigid. Violent spasms wracked her. Walls contracted madly, milking my cock.
"This... no... me... cumming..."
Her words fragmented. Orgasm crashed over her. Her face twisted in ecstasy.
But I didn't stop. Ignored her peak, kept thrusting. Overstimulation made her thrash.
"No, no! Too sensitive! Uuuuuh!"
Her voice turned to screams. Second orgasm hit before the first faded. Her whole body convulsed.
"Get it now? How fragile a human body is."
I flipped her suddenly. Face down, ass up. Thrust in from behind.
"Ungh!"
Her face buried in the pillow. I gripped her ass, pounding. Flesh slapped: smack, smack, smack, smack, smack.
"How... can you... cock. Good. Sex. Ass."
Her words weren't sentences anymore. Fragments spilled out. Pleasure waves scrambled her mind. Like ordinary demons, listing words.
"Cock not pussy flower field. Fuck pleasure sex cock sleeve."
I gripped her waist hard, delving deeper. Each cervix stab made her spasm. Piercing teased my tip.
"Haa... unghiiit!!"
I was close too. Limit approaching. Her walls still stimulated supernaturally. Demonic power lingered, but now I owned it.
"Where should I cum?"
I yanked her head back by the hair, whispering in her ear. Her back bowed like a bow.
"Please... inside... inside... cum inside... please."
First time her voice held begging—and dialect. No longer commanding, pleading. Choi Seo-ah's brain syncing with the demon.
"Yeah, I'll fill you up."
Final deep thrust, tip sealed to her cervix. Explosive release surged.
"Uuuuuh!"
I felt cum erupting inside her. Her body shuddered in spasms. Walls pulsed, squeezing every drop.
"Aaaaaah!"
Her scream echoed. Third orgasm hit. Violent tremors.
Spent, I collapsed on her. Both panting raggedly. My chest to her back, heartbeats shared.
Slowly pulled out. Cum leaked down her thighs.
I flipped her, facing her. Eyes still inhuman. But new emotions dwelled—fear? Awe? Just pleasure-drunk?
She panted pleas at me.
"No... if we sync... I'll... disappear."
I gripped her slender neck tight.
"You knew who I was and still fucked around?"
"Haa... Master... stop... stop that cock... please."
Two voices clashed. Demon half-synced to Choi Seo-ah's brain, half-resisting.
"Demon hunters exist to kill demons."
"A demon hunter?"
I started choking Choi Seo-ah's neck.
"Kek? Gek?"
Choi Seo-ah's eyes bulged, legs kicking.
"I'm really curious about your identity. Soul Harvest will reveal it. Don't resist—die by my hand, demon bitch."
Choi Seo-ah's face turned red, terror rising. Heels shoved sheets away in futile rebellion. No match for a demon hunter.
Black mist rose from her eyes.
"Kruuuugh... no... this can't..."
Her voice wasn't Choi Seo-ah's or the demon's—layered, discordant chorus.
Choi Seo-ah's body convulsed. Back arched unnaturally, spine near-breaking. More stimulation hit my cock.
"Uwaaaaaah!"
Her scream filled the room. Then her mouth tore open—beyond human limits, like a snake unhinging jaws.
"Kraaaaaah!"
Black smoke billowed from the ripped mouth. A form emerged slowly. Silhouette first: horned head, clawed slender arms, bird-like legs.
"Uuuuugh!"

Something kept pouring from Choi Seo-ah's mouth. Like peeling off a sock, the demon exited her body. Her skin shriveled rapidly, losing elasticity—like an emptied leather sack.
With my shout, the last piece of the demon slithered out. Left on the bed: wrinkled human skin, like discarded clothes. My cock slipped free naturally, leaving a cum-filled skin pouch.
Room air chilled instantly. The demon's true form appeared before me. Grotesque monster: woman's breasts on bird legs.
"Fuck... a demon hunter. What the hell are you doing in T-16?"
"Soul summon sponge bob, kuma, puu, explosive diarrhea."
The demon sneered at me.
"Insane. A demon hunter using Lucifer's power. What the fuck are you?"
"Beat that fucker's ass."
I commanded my summon and formed a fireball. But the freak dodged swiftly, hurling toward the window.
Crash!! Glass shattered as it spread wings mid-air.
I hurled the fireball, but it flapped away, evading nimbly.
"Unbelievable. Using Van Helsing's hellfire... Van Helsing was killed by Baal in T-12..."
"You... what are you?"
"Can't you tell by looking?!"
The cocky monster suddenly glanced skyward. Ignoring our standoff, it glared up.
"Wait. Hold on. I didn't say shit!"
Target switched. Pleading to the sky.
Blinding light engulfed it. Intense beam from above—hard to even look at.
I shielded with my arm, peering. No trace left, not even a scream—the monster vaporized.
Overwhelmed by the sky's energy blast, it perished mid-air.
"Dead?"
Just like that?
