Shell Experiment 2
Just before drifting off to sleep, the last thing I saw was Choi Seo-ah lying on the bed. The body now possessed by the demon showed no sign of movement, as if it had fallen asleep. I'd only leaned back in the chair while organizing my research notes, exhaustion washing over me, and suddenly my consciousness faded.
A hazy sensation in my dream. Something warm, wet, and soft enveloped my lower body. Pleasure made my body react instinctively, my eyelids fluttering.
"Nngh…"
A moan escaped my lips. The sound snapped me awake. When I opened my eyes, the room was shrouded in darkness. But the pressure on my thighs was unmistakably real.
As my eyes adjusted to the dark, shapes emerged. Choi Seo-ah… no, the demon inhabiting her body was straddling me. Her bare legs wrapped around my thighs, her hands fumbling with my pants zipper.
"What… what the hell are you doing?"
Her face turned toward me. Even in the darkness, her eyes gleamed unnaturally. That gaze was anything but human—like foxfire flickering with eerie allure.
"…Master."
A sound leaked from her lips. Slurred and mechanical, but unmistakably meaningful. The word I'd imprinted on her.
"You… you can talk now?"
Instead of answering, she just moved her fingers. Still clumsy, but far more skilled than before, she pulled down my pants. Before I could react, she took my cock into her mouth.
"Huuuugh!"
The sensation of being sucked into her hot mouth made my whole body shudder. Her tongue wrapped around my shaft, moving with expert precision—but somehow mechanical. It was as if memories lingering in Choi Seo-ah's body were guiding her.
"Wait… but you're supposed to be a virgin…"
Her tongue piercing grazed the base of my cock and slid upward. Sharp pleasure shot up my spine. Suddenly, she pulled her mouth away and climbed fully on top of me. Her face remained emotionless, but her eyes burned with something primal. Desire. No, something even more basic. Hunger.
"Serve… Master…"
Her words were still slurred, but the intent was clear. She started moving her hips atop me. Her pussy was already soaked, rubbing my cock against her entrance.
"You can't… fully control that body yet."
The corner of her mouth twitched upward. Less a smile, more an instinctive twitch. Then she slowly lowered herself. My cock pierced her pussy entrance.
"Uuuugh…"
A low moan escaped her. The pressure of her hymen tearing. Yet her already slick insides sucked me in effortlessly.
"Not just piercings on your clit and asshole, huh."
Incredibly, there was a piercing on her uterine wall. When my glans hit bottom, the cold metal touch sparked electric ecstasy.
"You crazy bitch… a piercing in your womb."
Without a word, she began moving her hips. Awkward at first, but she quickly found a rhythm. Like an old machine lubricated and running smooth.
"Are you… reading Choi Seo-ah's muscle memory?"
Her eyes fixed on me. Even in the dark, their color seemed to shift. Not human eyes. Something writhed inside them.
"Master… feels good…"
Her inner walls began squeezing my cock rhythmically. Conscious control, no doubt. She was manipulating her vaginal muscles at will.
"How… so fast…"
She circled her hips slowly as she sank down. Then suddenly braced her arms on my chest and brought her face close. Our eyes met, sending a chill through me. Something watched me from those depths.
"Master… cum… please…"
Her pussy muscles clenched harder, gripping me. This was beyond human control. Her walls wrapped, rubbed, and sucked my cock like a living thing.
"Fuck… this is…"
The clumsiness was gone. Her body overwhelmed me in perfect command. Her hands pinned my arms, legs clamped my thighs. Her lips hovered at my neck. Cold lips brushed my skin, raising goosebumps. Then she sucked hard.
"Ah… what the…"
Pain and pleasure mixed. She sucked like she was marking me with a hickey. Her hips grew more violent. My cock plunged deep, the metal coldness at her cervix driving me insane.
Human cumdump? No, Choi Seo-ah had transcended into the ultimate fucktoy. Her hand moved to my pounding chest, feeling my heartbeat. The other wrapped my throat—not crushing, but pressing firmly. Terror surged. Was this demon going to kill me? I wouldn't go down easy, but…
Her moans and hips continued. Not to harm, but to savor my heartbeat fully.
"Haa… Master… more…"
Her rhythm accelerated. She dominated completely. Had I tamed her, or had she hunted me? I thrust up to match her, and her walls clenched tighter. Her nails dug into my chest—sharp, but not deep.
"Ugh, grrr…"
Her body stiffened. Orgasm building. The hand on my throat tightened then released. Her pussy pulsed.
"Haaaaah!"
Her climax hit. She arched wildly, trembling atop me. The intense contractions pushed me over.
"Me too… gonna cum…"
Her eyes turned to me. Then she suddenly dismounted. My cock slipped free.
"What—"
Before I finished, she bent between my legs and swallowed my cock deep—to her throat. She sucked fiercely.
"Uuuuugh!"
Unbearable pleasure—I came instantly. Semen erupted into her mouth. She gulped it all without flinching.
"Haa…"
When she pulled away, faint moonlight revealed white liquid trickling from her lips. She scooped it with a finger and swallowed.
"Master… delicious…"
She crawled up my chest, stopping inches from my face. Her eyes gleamed unnaturally in the dark. Something inhuman lurked within.
"More… please…"
Her hand reached for my cock. Already spent, but it hardened again under her touch. Her control over my responses had skyrocketed.
"What… the fuck are you?"
Instead of answering, she mounted me again—this time facing away, reverse cowgirl.
"Serve… continue…"
Her hand guided my cock to her asshole. Wait, this…
"Hold on, that's—"
She sank down without hesitation. My cock penetrated her ass. Slick with saliva and juices, it slid in surprisingly easy.
"Uuuugh…"
Her insides were scorching hot and gripped fiercely. Her anal muscles contracted around me—inhuman control.
"Haa… good… Master…"
She began moving slowly, rising and falling, devouring my cock with her ass. She twisted her hips at impossible angles, taking me deep. Piercings in her anal walls raked my shaft with intense pleasure.
"Fuuuuck!!!"
I cursed involuntarily, grabbing her hips. Her hand rubbed her clit frantically, the barbell piercing glinting as she chased ecstasy again.
"Fuck… this even possible?"
Her body glistened with sweat, pussy juices, and cum. Her pace quickened.
"Master… harder… more…"
I thrust up instinctively, syncing with her descent. Our rhythms merged; her moans grew louder.
"Aaah… haaa…"
Suddenly she folded forward—incredibly, folding her body until her head neared my feet. Beyond human flexibility, grotesque yet erotic. In this pose, she spread her labia wide, showing me her dripping pink insides. Her ass still impaled on my cock.
"Master… here too…"
I got it. I lifted my hips and latched onto her clit. Her moans exploded. This was no human sex—an obscene ritual by a demon in human flesh. Her flexibility, stamina, muscle control—all superhuman. Like the girl's head spinning 360 in The Exorcist, but optimized for fucking.
"Haaa… cumming… Master…"
Her ass clenched violently. Her pussy spasmed open. Dual orgasms from both holes.
"Haaaaaaaak!"
Her scream unleashed a geyser of squirt, soaking my face. The stimulation broke me.
"Me… cumming…"
I erupted into her ass. Her insides milked me pulsing. Reality-warping ecstasy.
She twisted back with impossible grace, collapsing onto me. Her face hovered over mine. Her eyes now shone a different color.
"Master… so good…"
Her voice was far more natural, laced with emotion. She licked my cheek—tasting her own juices. Then whispered in my ear, cold breath tickling.
"More… please… Master. Still… hungry…"
Her hand gripped my cock. Incredibly, it hardened again. Her touch was magical, knowing exactly which nerves to stimulate.
"You… what the hell…"
She sealed my lips with hers. Her cold, pierced tongue invaded, tangling with mine. Semen lingered on her breath. Even kissing, her hand stroked relentlessly. The other probed between my cheeks.
"Wait, what—"
Her finger teased my asshole, then pushed in slowly. The unfamiliar intrusion tensed me.
"It's okay… Master… you'll like it…"
Her finger explored, hitting a spot. Electric pleasure surged. My prostate.
"Uuuugh!"
My moan made her lips curve. Her expression neared human, but still alien. Those eyes—inhuman.
"Master… let me do it…"
She mounted again, taking my cock into her pussy. Her finger still massaged my prostate. Dual assault—I was her puppet.
"Fuck… this…"
"Good, right? Master… more…"
Her movements intensified. Pussy walls milked perfectly, hitting sensitive spots. Finger rhythm synced.
"Haa… gonna… again…"
"Yes… Master… inside me…"
The third orgasm loomed. This wasn't normal. She controlled my body, my responses.
"Uuuuuugh!"
Explosive release—vision flashed white. Unmatched intensity. As consciousness faded, her voice echoed.
"Master… I'm getting… used to this body…"
Her eyes met mine. Clear intelligence dwelled there—inhuman.
"Soon… more fun… play…"
Her final words pulled me into total darkness. Even in exhaustion, I felt her hands roaming. The demon had claimed Choi Seo-ah's body—and now sought to claim me. Hunter and prey reversed.
Mental attack detected. Mental defense system activated.
At that moment, the cold alert sound echoing in my head snapped me back to my senses.
