Mana Rampage 1
"Why... won't you even look at me? Why? I... always remembered your birthday... and Valentine's Day too..."
A voice repeating the same words like a broken recorder. I turned at the familiar sound. Gu Mirae? She shot up from her seat and started glaring at me.
"...Why?"
"Oh my. Woojin-ssi, that woman's... acting strange. Mana rampage, maybe? Do you know her? She's only glaring at you."
Han Areum's words jogged my memory of what a mana rampage was. The Awakening Fruit was originally Baal's corrupted mana seed, meant to build his legions. No one in this world knew the truth: hunters and demons were separated by a single sheet of paper. The moment a hunter's mind crumbled under intense emotional shock or got eroded by heart demons, that seed sprouted, twisting the host into a demon.
Gu Mirae was starting to go through that mana rampage right now. Spotting me in that intimate moment with U Mi-young had been the first trigger. And seeing me all chummy with Han Areum? That must've been the final blow, snapping her last thread of sanity.
"Fuck... it's a mana rampage! That woman's a hunter!"
"Everyone, get back!"
"Call the Hunter Association, quick!"
Screams erupted as panic spread. That's when I saw it. Something sleek like a snake slithering out from under Gu Mirae's prim office skirt.
Shit. No one could witness her turning into a demon. I unleashed my mana, frying every electronic device around us. At the same time, I knocked Han Areum out cold.
"Why—?"
She tried to shout something before collapsing. Couldn't let her—who was gunning for my weaknesses—see my full power.
"Park Woojin!!!"
Gu Mirae's voice calling my name echoed. Her form was morphing into the classic succubus straight out of subculture tropes. Her blouse ripped as wings began to flap.
"That's right... now that's a proper succubus."
I scooped up her soft, yielding body and focused Holy Flames at my feet, slamming down hard.
BOOM!!
The floor caved with a deafening crash. Holding Gu Mirae tight, I plunged into the darkness of the underground parking lot.
My feet hit the cold concrete. An unnatural heat poured from her body, scorching the air. Her scent had changed too—dense, primal, like pheromones luring any man in.
Her blouse tore further, revealing jet-black bat wings that flapped wildly.
"Haaahhh..."
A moan leaked from Gu Mirae's lips. Not her usual timid whisper, but something lewd and lascivious, like a cat in heat.
"Gu Mirae, snap out of it."
I grabbed her shoulders and shook. She slowly lifted her head, gazing up at me with hazy eyes.
Swish swish.
A black tail slipped from under her skirt, coiling around my thigh like a living thing.
"Can I call you oppa now? Ahh~"
Her voice dripped with a sultriness I'd never heard before. The shy girl who could barely meet my eyes was gone, replaced by something entirely different. Her pupils spun dizzily. She flicked her tongue over her lips, then wrapped around my neck.
"I get it now..."
"Get what?"
"How much I love you, oppa... And how much I've hated and suppressed myself because of that love... I finally understand."
Riiip—
She tore off her blood- and dust-stained blouse in contempt, tossing it aside. Her slender white torso revealed a hidden bra.
"Oppa... my breasts are so small... I was always so ashamed. If they'd been big and pretty like other girls', maybe you'd have looked at me once... I cried every night. What an idiot I was."
She unhooked her bra herself. Freed from its chains, her small breasts were perfect hemispheres, pink nipples erect like cherries from shyness and arousal.
She no longer hid her body in shame. She displayed it proudly, gauging my reaction.
"But look at this apple hips... You know how hard I worked out for you? Lots of thigh exercises too... My grip's gonna be amazing. How's my virgin pussy?"
This wasn't demonic possession—it was pure Gu Mirae, her true heart laid bare. I knew her desires centered on me, but this wasn't the demon's seduction. It was one woman's lifetime of twisted, fiercely pure devotion.
"I never... not even once with Ra Seung-gun. Sexual aversion disorder? No, the truth is..."
Her tail uncoiled from my thigh and slithered between her legs, the heart-shaped tip brushing her soaked core.
"Ahh! Hnng... The truth is... any man but you... just the thought made me sick..."
Her voice trembled with pleasure. Her "illness" wasn't trauma. It was a viciously chaste imprint, prepared solely for one man. And that imprint had finally restored her true self.
"Just thinking of you, oppa... gets me this wet..."
She hiked up her skirt, revealing pure white lace panties, the center soaked transparent with her juices.
"Mmm... weird... this tail... moving on its own... keeps... keeps touching..."
The tail nudged the lace aside, exposing swollen pink lips. Clear nectar dripped like honey from the shyly closed bud.
"Oppa... look... how much I've wanted you... waited for you..."
She spread her legs, fingers gently parting her deepest folds. The inner pink flesh twitched, contracting and relaxing as if desperately awaiting me.
"Mirae... you really..."
"Yeah... virgin... pure for you alone..."
Tears streamed from her golden eyes. But these weren't tears of sorrow anymore. They were joy and ecstasy from breaking free of long suppression, finally facing her true master.
"Now... now I can give you everything... all of me..."
She pressed close, serpentine in her grace, unbuttoning my shirt one by one. Electric tingles sparked wherever her fingers grazed.
"Oppa... I'm not scared of anything anymore... with you... anything..."
Her hand tugged down my zipper. My fully erect cock sprang free, and her red eyes blazed brighter with awe.
"Wow... oppa... so... so big... beautiful... nothing like Ra Seung-gun's..."
Pure wonder and blatant anticipation mixed in her voice. Her tail quivered unconsciously, betraying her extreme arousal.
"Oppa... can I... put it in my mouth?"
Gu Mirae knelt reverently before me. She brought her face close to my twitching length, treating it like a holy relic. Her hot breath hit the sensitive glans, making my body shudder.
"Mmm... the scent... so good... your smell..."
She sniffed deeply, savoring my musk. Her succubus transformation had sharpened her sense of smell to the extreme. To her, it was the ultimate aphrodisiac, stronger than any perfume.
Chuuup...
Her soft lips met the tip. Not just a kiss—this was devotion, infused with years of longing. Pleasure surged through me like lightning.
"Mmm... so tingly... but... I love it... so much..."
She extended her tongue, licking slowly along the shaft. Her bifurcated succubus tongue looked snakelike, but the sensation was beyond imagination. The twin tips stimulated different spots at once, delivering bizarre, intense pleasure I'd never known.
Her lips enveloped the head. Her small, cute mouth took me deep and soft, thanks to succubus prowess. The hot, wet interior numbed my nerves. It was a sanctuary of bliss made for me alone.
"Nngh... filling my mouth... your presence..."
Her muffled voice was hazy with pleasure. Her saliva drenched me—stickier than human spit, sweet like honey.
She found a rhythm, bobbing up and down, sucking and releasing. Clumsy, but that raw eagerness to please me made it all the more arousing.
Meanwhile, her tail began teasing her own most sensitive spot.
"Mmm... oppa... me too... feels so good... making you happy... makes me happy..."
The heart tip rubbed her clit gently. Double waves of pleasure made her tremble.
She was discovering self-pleasure for the first time via her tail.
"Ahh... this is... amazing... my body's... not mine anymore... reborn for you..."
Her tail grew bolder, the heart slipping past her dripping entrance to her shyly puckered rear.
"Haaah!!"
Uncharted pleasure shattered her expression. Mouth on my cock, tail in her ass—the sensory overload hit like a storm.
Chuuup... mmm... oppa... I'm... going crazy... too... too good...!
Her back wings flapped wildly with excitement, stirring the parking lot air, mirroring her emotions.
Her first climax approached.
"Uwaah... oppa... something... gonna burst...!"
"Nnghh! Gulp... aaahhh!"
She peaked, body convulsing. Wings flared wide, the motion pushing me over the edge too. I lost control, flooding her throat deep. She swallowed every drop, moaning in satisfaction.
"Fwaah... oppa... delicious... more... give me more..."
She licked her lips, looking up with innocent eyes. Lapping up the white remnants was obscenely erotic.
"Oppa... now... I'll give you my virginity... saved for you."
Gu Mirae stood, shoving me onto a cold car hood. Her unleashed succubus strength surpassed most hunters.
"Oppa... I really... want to be yours... body, heart, soul... all of it..."
Straddling me, she whispered. Her small breasts pressed against my chest, hard nipples tickling my skin.
She lowered slowly, aligning my cock with her entrance.
Squish—
"Aaah... hurts...! But... so good...!"
Sharp pain from her torn hymen mixed with ecstatic bliss of finally taking her lifelong love. Tears flowed anew, but her face shone with utter happiness.
"Nngh... oppa... finally... we're one..."
She began rocking atop me. Her small breasts bounced resiliently with each motion. Tail coiled my legs, wings enveloped us in our private dark cocoon.
"Ahh... oppa... too... too good... first time feeling this... can't hold back... waited so... so long..."
She moved fiercely. Her walls clenched hotly, refusing to let go.
Suddenly, she spun around, back to me. Her pert ass and tail were on full display.
"Oppa... how's this? Feels... deeper..."
Unsatisfied, she dismounted, dropping to all fours. Her tight ass lifted high, pink rear folds winking invitingly. Her tail guided me like a living hand.
"Nngh... slow... oppa..."
I pierced her anew. She shuddered. A whole new dimension of sensation.
"Aaah... coming in... so deep...!"
Squelch!
Her succubus body adapted far better than human. Her walls hugged my girth effortlessly.
I grabbed her horns; she toppled back, impaled.
I thrust brutally, as if to break her tiny frame. Wings battered us wildly, echoes filling the lot. She climaxed again, screaming in rapture.
"Haa... haa... oppa... I'm... completely yours now..."
Gasping, she whispered. I flipped her into my arms, plunging back into her soaked pussy.
"Haaang!? Again...?!"
Despite her surprised moan, her hips ground against me, taking me to her cervix.
"Now... truly... your woman..."
Deep in her writhing walls, I erupted again, filling her completely.
Spurt. Splurt.
"Haaa... gonna lose my mind..."
Her eyes unfocused in orgasmic waves. Then, the mana flooding her body drained like an ebbing tide.
"Haaaaang!!"
As she clung tight one last time, her tail, wings, and budding horns dissolved into light particles.
"Haa... haa... what... happened? Oh... Assistant Manager Woojin...? I... what did I... why am I like this?"
The succubus traces vanished; her cheeks flushed crimson. Back to the shy, ordinary human girl.
But we were still joined at our most intimate.
Thump. Thump. Thump.
Her heartbeat transmitted straight to my chest.
"L-let... let me go, sir. Sob sob... this is... a dream..."
I slowly withdrew—then thrust deep again, to her core.
