Neuroscientist's Hell 2
Clumped black hair, sticky and thick, gathered under the sink.
"What the hell..." O Nangryun cautiously bent down and grabbed the hair clogging the drain with his hand. Cold and slimy to the touch. The hair was soaked—not in water, but in some viscous fluid.
"Feels kinda creepy, don't it?" O Nangryun gave it a light tug. The hair was heavy, tangled somewhere. He put some strength into his grip. The more force he applied, the slower it pulled free. Pop.Clunk. Clunk. As the hair dragged out, something inside the drain seemed to snag.
O Nangryun kept pulling while peering into the small round hole. "Where the fuck is it caught?" He wanted to check what the hair was hooked on. Probably the pipe filter or something. But as he looked down the drain...
Something appeared that shouldn't have been in his line of sight. O Nangryun's hand froze solid.
"Fuck."
An eye staring up at him from the drain. A pale face with bloodshot eyes glaring from below.
"What the shit. Why's there a fuckin' head in the drain?" O Nangryun got chills. That eyeball had just blinked. The severed neck belonged to a full woman's face, black blood dripping from her mouth.
"A monster? A goddamn head monster..." The corner of O Nangryun's mouth twitched up, and soon he was cackling. "Holy shit. Is this heaven? Monsters exist! Hold on, buddy. I'll getcha out."
A head living in the bathroom drain fascinated him. Up close, her skin was fair and pretty. He wanted to yank her out and take a good look ASAP. Normal folks would've freaked, but not O Nangryun.
"Driver... gonna need a hammer and wrench too. Wait up!! I'll save ya!" Overjoyed, he bolted to the living room. Light steps as he grabbed his tools and hurried back.
But the hair clogging the drain was gone. Clean as could be.
"What? Where'd it go!! Head monster! Where ya at!!" O Nangryun yelled into the drain, voice thick with regret. But the head monster never reappeared.
He smacked his lips in disappointment. "Damn... a world with monsters... fuckin' sucks I lost it."
Still bummed, O Nangryun pulled out his smartphone to search for info. Every bit of internet content was a mess of meaningless consonants and vowels.
"What the hell. What's goin' on?" An hour later, O Nangryun reached a conclusion.
"This is fun? Definitely another dimension. Red sky... and that head monster too."
TV showed nothing but people grinning grotesquely. Just like his wife. Most humans lacked developed language. From a neuroscientist's view, he grasped it quick.
Human bodies intact, but regressed.
He recalled his favorite survival board. Otakus prepping for humanity's end. Someone posted today.
Yo. Am I the only one thinkin' the world's fucked? Did it get hacked? What's with the red sky? Fuck. Someone explain. It's not aurora, obvious as shit. Need a scientific breakdown.
O Nangryun was thrilled other survivors existed. He replied right away.
He waited for a reply, but nothing. Real-time chat seemed impossible. His stomach growled. He grabbed a tuna can from the pantry, nuked a pack of instant rice.
His stash of lazy-day rice packs stacked high. Ding. He shoveled it down while flipping on the TV. Reruns fine, but live broadcasts were all wrong. Some idol group called Showcase doing a strip show—pure chaos. Chewy idols bouncing soft tits while dancing got him hard again.
O Nangryun scratched his crotch and headed back to the bedroom. Wife still ass-up, screaming.
"Ah, this kinda welcome."
He railed her from behind like before. She didn't seem to feel pain, so he pounded her squishy body destructively. Shoved his dick in her screaming mouth—no teeth, no bite.
"Mouth pussy's top-notch!" Creampied her pussy and ass raw. She kept screaming.
"Just lose the noise, perfect."
A bit-loud fucktoy now. Eat, shit, eat, shit. O Nangryun was thrilled. World changed, but water, power, comms worked. Holes to fuck at will. Stuffed panties in her screaming mouth to mute her.
"Voice gonna give out."
Short break, checked the board again. HotHusband replied.
"Demons in human shells?" Absurd, but red sky and wife's behavior fit.
"Joker Smile... that creepy TV grin?" O Nangryun approached his still-screaming wife. Grabbed her cum-matted hair, forced her head up. She screamed at him. He pressed his face to hers and flashed the Joker Smile.
Shockingly, her screams stopped.
Oh ho? And she mirrored the Joker Smile back.
Mirroring effect. Foe-friend identification...
House went quiet without her screams. She rose from bed. Drip. Wiped cum from her crotch. Tilted her head. O Nangryun observed calmly.
Screaming logic off, back to normal patterns. Body dirty, so to bathroom—shower time.
He eyed the drain—no head monster. Watched her shower while munching nuked frozen chicken.
"First time watchin' a chick shower."
She rinsed creampie cum from her crotch, ass, then scrubbed pussy with feminine wash.
Cerebellum and hippocampus functional. Simple actions on machine-like repeat. Language center busted.
Post-shower, she toweled off, tossed it in hamper. Fresh panties from drawer, blow-dried wet hair. Movements fluid as water. Mirror-gazing, hair-drying—spotted O Nangryun behind, startled, then Joker Smile.
O Nangryun watched her at the vanity. Blow-drying, but wind hit wrong spots—not her hair.
Remembers actions, no context.
Stimulus-triggered repeats. Creampie? Wash crotch. Cum in hair? Shampoo.
Hippocampus memories react to stimuli.
Observing revealed "demon" mechanics.
Stimuli, huh? Test time.
From behind, hands to tits—squeezed plump breasts, teased nipples. Her pupils quaked. But panties soaked with juices.
Reacts to stimuli, alright. O Nangryun grinned.
Gonna mod you proper.
Joker Smile to calm her. First: blindfold her eyes. Block biggest input—vision. AirPods in ears, noise-canceling on. Sight and sound gone, her hair-drying froze. She sniffed hard, seeking scent info.
"Yup. Pulls hippocampus/cerebellum memories from surroundings."
Block vision/hearing—biggest senses—and she halted, docile. Simple algorithm. O Nangryun pitied these "demons." Stimulus-driven like bugs.
Blindfold and cloth heightened her sharp nose and lips. His lips neared—flinch—hers pursed. Sensitive to breath, touch. Sensory deprivation amped tactility.
Slow nipple caress. Inverted nips hardened. Tongue circled, sucked hard. Down below, clit hood peeled, swelling. Squirt! Squirt. Fluids jetted from her slit. Trembling like a leaf. Random orgasm? Just from touch.
"Yup... no sight/sound, hypersensitive."

Sucking stiff nips, he scooped her up. Warm body wrapped him. Hands under thighs, she coiled arms round his neck. Natural kiss started. Her tongue snaked in like a serpent. Spread thighs wide—slit gaped willingly. Aligned throbbing cock, lowered slow. Tight warm walls gripped his shaft.
"Haaaah~"
She arched back, moaning, neck coiling tighter. Bouncy tits and slender frame clung like a cicada, writhing serpentine. Not one-sided pounding—mutual, kissing, lovemaking sex.
"Fuck... this is it."
Slam. Heavier drops inevitable, deeper thrusts, bigger pleasure. She felt cock plunging deep, hugged his back tenderly—like loving a lover. Licked his neck, whispered moans in ear.
"Haaa~ Hng~"
O Nangryun realized: blocking sight/sound didn't just amp touch/pleasure—it fulfilled her desires.
"Vision/audio block completes law of closure."
[Law of Closure] Gestalt psychology principle: brain auto-completes masked faces. Aka "magician's law"—brain illusion.
"Your brain's paintin' me as your fave heartthrob, huh?" No face? She imagines idol actor she loved. Explains eager fucking. Her hips flexed fluidly. Touch-induced orgasms? Law of Closure.
He thrust-lifted, savoring pleasure. Creampied while kissing. She kept hips moving mid-kiss. Horny bitch milking balls. Orgasmic bliss, goosebumps everywhere.
"Haaang~"
Her moans echoed lewdly. He ramped speed in lift-thrust. Legs dangled shaking, arms yanked him tight.
That's right!
Then—Beep beep. Beep beep beep.
O Nangryun froze mid-thrust. Someone at the door. Punching code familiar-speed.
Beep ring~ Click.
Door opened. O Nangryun faced an unexpected visitor.
