Rehearsal Before the Wedding

Yehwa instinctively sensed danger from the hot heat spreading through her lower belly.

The feeling of blood rushing to a single point, the dizzying stimulus that coursed up her spine every time the space between her thighs tightened, was erasing her reason.

A violent thirst—her body demanding something with brutal insistence. It was impossibly hard to ignore the instinct screaming that satisfying this thirst would feel so very good.

'Why... is my body... no! Not with anyone but Taehyun...!'

Memories of the boy she'd always been with cooled her body down. Walking the campus together, talking for hours—the chill of the bench and the warmth of his palm against the back of her hand.

But the longer she glared at the girl-shaped figure aiming at her right in front of her, the stronger the thirst between her legs grew. She fired mana bolts at the figure every time it drew close, and every one scattered like a mirage. The hotter her body became, the harder it was getting to tell illusion from reality.

'On paper, Im Yehwa's an A-Rank because of her ability, but her actual combat power barely scrapes C-Rank. And even that's thanks to her barrier and the speed and power of her mana bolts, reinforced by her skill. Take those away, and she's basically a scarecrow.'

Im Yehwa's stance began to visibly fall apart. Her breathing turned ragged, her cheeks flushing red. Every time she inhaled, a white bra showed through her sweat-damp blouse. At the sight of her peach-toned breasts heaving, my cock surged up so hard it threatened to tear through my pants.

She loosed a mana bolt at me as I charged at her with both arms outstretched toward her chest. I diverted my gaze into a Reverie-crafted mirage and gathered mana in my mouth.

Tang! Tadadang!

"..! Hngh! Again!"

Yehwa stretched her arms toward the mirage once more, concentrating her mana. I took in her delicious side profile, pulled her cheek toward me, and stole her lips.

Her stunned blue eyes met mine in wide-eyed shock. I coiled my tongue around her soft, damp one, snake-like, and tangled them together.

"Chwup♥... jjok♥ churyurup♥"

'Ohh... the main heroine's mouth-pussy, kept pure for the protagonist♥ This is fucking amazing♥'

"Ugh!... Uuugh!!"

'Her tongue tastes like flowers! The mouth-pussy the original protagonist reserved for himself♥ I'm gonna devour it♥'

The mana gathered in my mouth wove its spell through my saliva, which she'd swallowed, in an instant. The moment Charm manifested inside Im Yehwa's body, the strength drained from her entire trembling frame. Her buckling legs gave out, and the wet sound of arousal squelching softly tickled my ears. I pressed my cheek against her rolling tongue.

Tears welled at the corners of Yehwa's eyes. The mana gathered in her arms was flowing back to me. Her concentration fractured again and again, unable to build her spellcraft. I pulled my mouth away and swallowed her saliva.

Within her lust-drunk body and burning cheeks, I could see a gaze full of fury directed at me.

"..Chwp.. ung! Heungk! That's too far... that was my first kiss!"

"Sorry, noona. I was so turned on I couldn't help myself."

'She's in heat enough that ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠spellcasting and incantations are beyond her. Should be fine now.'

The satisfaction of having savored the heroine's lips—lips I'd only ever seen through a screen—and the sight of the beauty's sensual body ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠lying helpless, preparing to receive my cock, made the corners of my mouth curl up on their own. I mouthed an apology, but I couldn't wipe the grin off my face for the life of me.

The moment I pulled down my zipper, a thick cock flopped out and covered Im Yehwa's face. An intense yin energy leaked from the fat, long shaft, resonating with the aphrodisiacal property of my mana. The Charm that had seized Im Yehwa answered that yin-energy-laced mana's call. Her nose and lips fell into sync with instinct itself, now enslaved to the Charm.

With her eyes gone hazy, she licked at my cock with her tongue.

I cast a blurred dream through Reverie. The moment a fellatio dream—built from my encyclopedic knowledge—flickered through her head, her cherry lips and tongue wrapped around my cock and began to suck it down.

The sensation of her tightening and suckling the glans and the shaft nearly bent me in half. I braced my thigh against Yehwa's soft breasts for support. I could feel the soft nipples digging into my knee and her tongue kissing the tip of my cock all at once.

"Hnngh... noona, that's unfair... my cock was saving its first kiss too... ohh♥"

"Ubbup.. chwup.. jjok.. chwububup♥"

While I savored the awkward, unfamiliar pressure enveloping my cock, a subtle stimulation from my balls made me wrap my hands around Im Yehwa's head. She understood the urging, and the wet sounds of her slurping my cock grew faster.

"Chwup! Chwubup ubbup! Syuryurup!♥"

"Hahk! Hahk! Noona, I'm coming! Swallow all of it!"

Byureureureuk! Byureureureut!

-"And put strawberries on top~ Aahn~"-

"Ubbup.. up.. uum.. gulp..."

The dizzying stimulus firing up my shaft bent my hips toward Im Yehwa's face. I carefully fed my cock down her throat and came, my balls tightening. Her tongue and lower lip were gently lapping at my sack. I rubbed my thigh against Yehwa's soft breasts, then wiped the last of my cum clean on her tongue.

Im Yehwa's lips connected to the tip of my cock through the slick trail of love juices and saliva mixed down her legs.

'No resistance at all? As expected of EX-Rank power. Even a high-ranked Charm usually struggles the stronger the bond between lovers.'

If she hadn't been saving her virginity for marriage, or if my Charm had only been around S-Rank, I honestly wouldn't have been able to shake the anxiety in the back of my mind. In the original story, there'd been an event where an SS-Rank Charm broke precisely because a couple's bond was deep and strong.

"Haang♥ Haaa.. Haaang♥"

"Sex.. adulterous sex with the big-titted main heroine!"

The moment I roughly peeled off Yehwa's clothes, her peach-colored breasts wobbled enormously. I kneaded them until my fingers sank in, bit her nipples with my lips, and sucked them with my tongue. The stiff nipples twitched along with her body.

"Hahk! Haang♥ My chest feels good...♥"

"Chwp.. Yehwa noona's pussy wants to have its first kiss with my cock too, apparently..."

"No... not there... eung♥"

Listening to her moan feebly, I pushed up her short skirt and stockings and tugged her panties aside. Her two most sensitive petals, soaked beyond dripping into a puddle, quivered open and shut.

I laid Im Yehwa down as if embracing her, my cock standing rigid and thick as her thigh, while I sucked at her chest.

"Kyaang♥... Haaang... chwup, chok♥"

I moved my mouth from her nipple to lick Yehwa's tongue. My glans, slit straining to burst, kissed the hole where her cum was meant to go. Yehwa's body jolted, goosebumps rippling through her at the sensation of a glans far thicker than her entrance.

-"When we get married, what should we name our child?"-

The dizzying sensation sharpened my vision slightly. Golden eyes beneath long, streaming golden blonde hair. Golden...? But Taehyun's eyes are black...

"Chwubk!! No!! Don't!!"

"Ohoo!?"

Im Yehwa wrenched her head back and shouted. A string of saliva connected her tongue and mine, achingly tender.

'The Charm broke even at EX?.. No, this is...'

I took a brief look inward at my body. Only half my mana was left.

'Did I overuse Charm? So that's why I put in so little mana. Perfect timing, actually—let's test something.'

Molkang-molkang♥

"Hang♥!? No! Don't suck!"

"Syuuup!"

Unlike her mind, which had wrenched backward, everything below her neck remained firmly within the Charm's spell, untouched by the break. When I activated Energy Absorption, mana began trickling to me through Im Yehwa's soft breasts and nipples, delivered via my mouth and palms. The amount coming through my mouth and her nipples was double what came through my palms alone.

Mana that had been at half filled back up to ninety percent.

"Ahhk!? My mana!?"

'Well, my tank's tiny since my body only just awakened, after all.'

"Just give up and enjoy it, noona. The fact that I was your first kiss isn't changing~"

Yehwa seized my forearm with ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her trembling arms. Through them, I could see the silver ring on her ring finger.

'The couple ring she wore before switching to her engagement ring, then. So this is what it looked like.'

Marinated in Charm and body fluids, fondled and stroked, she seemed to have lost all strength in her hips. She glared at me, brow furrowed—but thanks to her gentle eyes and round pupils, even her angry face gave off the taste of a kindly female in heat.

"You..!! Heungk!.. I'll never... forgive you!!"

"Ah♥ If you scold me while your lower mouth goes chuchu, I can't hold back♥"

"Hauk!? No!"

The moment Yehwa's body tensed with rage, a pleasant stimulus traveled to my cock, still kissing her two petals. I split the forty percent of mana I'd taken from Yehwa in two, pouring it into Charm and Reverie, and fired it into her head.

I gave her a dream of a date with Taehyun, constructed from my knowledge of the original story—and her eyes glazed over again, a silly smile spreading across her face.

I rubbed my glans against her pussy's entrance.

"Ah♥ But we're not married yet..♥ We can't..♥"

"It's fine, noona. We're just practicing for the engagement with pussy and cock♥"

"Practice♥ Taehyun, you want to get married soon too, don't you♥ Eiyt♥"

"Ohoo?!"

Yehwa rocked her pussy and lapped at my cock. My cock got coated in my precum, already glistening all over her pussy. I could feel the charm-tinged mana flowing from the precum soaking into her channel.

"Wait for me, Taehyun♥"

"Here I come, noona♥"

Puuk♥

I pushed my hips forward, sheathing my extreme-length incubus cock into Yehwa's pussy. The shallow membrane resisting my glans gave way with a pop.

-"When the baby's born, Taehyun, it'll probably look just like you, won't it?"-

The triple chorus of Charm, aphrodisiac, and mana swallowed the pain of her first time whole. The instant I entered, the Charm and Reverie lodged in Yehwa's head drained down below her neck. Reason returned to her eyes.

With the hot, slick sensation of a thick cock mashing her insides, her cervix kissed my glans. A supreme tightness worthy of the word "masterpiece" welcomed my cock in.

Chwup♥

"Euhet? Ohok♥?"

"Hnngh—thank you for the main heroine's virginity♥"

Jjibup♥ Jjibup♥

"Ook♥! Eut♥ I said we can't do this♥!?"

Jjibupjjibupjjibup♥

"Haang! Nooo! You can't feel this good!!♥ Taehyuaaang♥"

"Calling out another man's name with your groom right in front of you!? Yap!"

I ravaged the inside of Im Yehwa's pussy while rocking my hips roughly. As her channel bit down and sucked at my cock, convulsing with pleasure, the incubus mana seeped into her depths. Under the pincer attack of Charm and aphrodisiac, Yehwa's pussy rewarded me with an even tighter squeeze.

The obscene wet sounds of precum and love juices overflowing from where we joined filled the hall along with the slap of my hips. Following the incubus instinct, I funneled mana into only her weakest point as I thrust, and a sow's squeals spilled out of her.

Cheolpeok♥ Cheolpeok♥

"Hik♥?! Aang!♥ Haang♥! Chwup!"

She let her tongue slip free, beginning to drown in the pleasure my cock gave her, and I tangled our tongues together once more. I gripped her hips and thighs, lifted her up, and rose to my feet into a face-to-face seated position. So she wouldn't fall, Yehwa instinctively locked her arms behind my neck and kept the kiss going.

I lightly gripped her ass and prodded her weak spots with practiced hip work, and she wrapped her legs around my waist. The floral scent of her light beige hair tickled my nose. A pink heart flickered in her clouded eyes.

Kneading her ass, I savored the insides of Im Yehwa's channel and the weight of her breasts crushed against my chest. Walking slowly with her impaled on me, step by careful step, I made my way to the magic circle.

With one hand, I drew out the Serpent's Mana Stone I'd taken from the leader thug. I injected my mana into the strange stone—its scale-like surface spiraling, coiled like a four-leaf clover. The stone in my grip shimmered pink.

Pang♥ Pang♥ Pang♥

"Yehwa noona, lend me your mana~"

"Hang♥! Haang♥!"

"Can't even answer anymore, huh. Kukku."

Shuuuu

I absorbed Im Yehwa's mana and mixed it into the stone. A clear, serene blue—reminiscent of Yehwa's pure, gentle nature—flowed within the stone. The blue mana met my pink mana, and the two tangled and writhed like serpents. The blue mana refused to accept the pink; it entwined with it, but only circled, over and over.

As if waiting for its owner's permission.

'Im Yehwa's mind is extremely weakened by the shock of having her Charm subverted and her virginity stolen. Im Yehwa's Leap trait—the trait that accelerates the evolution and transcendence of whatever she's been intimate with. And the only thing that can carry that trait is Im Yehwa's own mana. And then there's the magic circle of evolution, which absorbs mana and reshapes an artifact's properties to match the owner of that mana.'

To use her mana, I needed the owner's consent.

Getting consent from a bitch in heat begging for my cock was extremely easy.

I am an incubus.

I poured Charm-infused mana into the magic circle and into my cock. The circle and my cock both flushed pink. The circle read the mana it had absorbed and rearranged the flow of mana around the Serpent's Mana Stone as its axis.

It was like a doctor observing a patient laid out on an operating table. In time with the circle's diagnosis, I pounded the charm-saturated cock deep into Im Yehwa's channel, over and over. A supreme, writhing tightness moved within her. The first orgasm of her life was approaching.

I was about to come soon, too.

Jjibup♥ Jjibup♥ Jjibup♥

"Hahk♥ Hahk♥ Haang♥ It's coming♥ Something! It's coming♥!"

"I'm coming♥! Im Yehwa noona! I'm coming in your womb! Get pregnant with incubus cum♥!!"

-"If it's a girl, Yejin! If it's a boy, Taehwa!"-

"Chwup! Sywup♥! Uum♥"

Byuryureut♥!! Byureut! Byureuk! Byureuk♥!

"Haum♥!! Paha! Ohoooook♥! Hauung♥!"

My glans kissed her cervix and fed it my cum. At the same time, I tangled my tongue with Yehwa's, injecting mana thick into the saliva and semen between us. A brilliant pink heart-pattern lit up in Im Yehwa's eyes.

Her womb suckled down the cum, and her channel responded with a clenching tighter than anything before, cheering on my climax. I kneaded her ass hard and buried my nose in her quivering breasts. Pearly white semen overflowed from where Yehwa and I joined, staining the magic circle.

"Phew.. that was fucking incredible..."

Jupon!

"Hang♥! Sowwy.. Taehyuna..♥"

My cock slid out with a lewd squelch. When I laid Yehwa down on the circle, the stimulation of the massive cock being drawn from her channel sent the cum-mixed juices spraying out in spurts. The incubus genes flowed like a valley along the smooth curves of her plump thighs and the creases of her ass, pooling into a puddle.

I planted my balls and ass on her big, soft breasts and pressed my long, thick cock to Yehwa's lips—chuchu. Her tongue slipped out and licked my glans.

"Clean it up for me, noona♥"

"Hehk♥ Hehk♥ Sywup♥ Chwup♥ Churyuryurup♥"

"Ooh! For a virgin, she's incredible at cleanup ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠fellatio!?"

Byureut!

Yehwa sucked down even the cum left in my urethra, flushed her cheeks, and slipped gently into sleep. The first torrent of pleasure she'd ever known had worn her mind out completely.

In time with the finish, the magic circle hummed and resonated with the Serpent's Mana Stone. The two spiraling currents of power inside the stone merged into one and resonated as well. Violet mana washed over the stone, then spread until it dyed the circle itself. A hot, lewd torrent of mana surged through the hand holding the circle and the stone.

The ominous purple mana flowed like water, enveloping the Serpent's Mana Stone.

Pajik-pajijik!

The scales of the stone bristled upward like thorns. The smooth serpent scales transformed into something rough and jagged, like armor. Between the coarse scales flickering with a faint pink glow, a violet core revealed its presence at the stone's very center.

The Serpent's Mana Stone's evolution was complete.

"Whew.. so, did I get everything done for now~"

I used Yehwa's soft breasts as a pillow and lay back, staring up at the hall's ceiling. Against the supreme softness cradling the back of my head, my cock stood rigid all over again.

An irreparable crack had been carved into a pair of lovers bound in the future. Even a touch full of lingering regret would be a fatal gash, sharp enough to cut them apart.

'Hold it in... I still have things to check, and cleanup to do.'

As I looked at the stone in my grip, something odd caught my eye. The shape of the core at the heart of the glowing violet stone was extremely peculiar.

"...A clover (♠)? No wait... a succubus tail?"

Dding!

"What the—give me back my Imoogi."

KWAAANG!!

"YEHWAAA!!!"
