Sister (1)

Episode 37

Faced with the freshly deflowered virgin pussy before me, I felt more dizzy than elated. Had I messed up even slightly, I might have lost my sub-class (Sage) again.

But.

『Quest』

----------------------

「Reward - Sub-class (Sage → Sage of Impurity)」

----------------------

Using Optimal Progression, I forcibly inflated the quest reward,

『Optimal Progression erases the remaining quest time.』

and obliterated the remaining time limit as if I had paid to skip it. I wasn't sure it would work, but it did.

『You have acquired the sub-class 「Sage of Impurity」.』

As a result, I was able to awaken as a Sage.

『Unique job skill 「Mind of the Strange Sage」 activates.』

...Though it felt like something was very off about this Sage.

『Sub-class 「Sage of Impurity (Legendary)」』

-A Sage who, upon reaching the age of wisdom (50 years), could no longer restrain his explosive desires and realized them through dreams

-An apostate who abandoned the path to sainthood and embraced corruption through indirect means

-Magic power increases by 115% when performing impure ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠acts

-------------------------

-Views all things in the world without prejudice and occasionally maintains a tranquil mental state.

--------------------------

『Unique job skill 「Dream Realization」』

-Can create one new skill every six months.

-------------------------

『Unique job skill 「Half-Spirit Body」』

-One who stands at the boundary between matter and spirit.

-------------------------

『Skill 「Mana Transport (Rare grade)」』

-Can gather and transport mana to a desired target location.

-------------------------

...Still, a legendary-grade job, no less.

The fact that it was of the impure variety was a bit concerning... but one thing was certain.

Park Ha-rin was now outmatched by me.

『Skill 「Dream Realization」 activates.』

That much was undeniable.

My sister, unable to hide her excitement, examined my body with keen interest. Her pupils shimmered with the thrill of victory—likely the satisfaction of rendering me immobile and taking me for herself.

"Ah..."

But after a brief shudder, she fumbled and grabbed my shoulders. Her tight pussy was blocked by the tip of my cock, refusing to let it in. A hint of irritation flickered in her gaze.

"You're too big. Shrink it."

Despite her words, she moved her hips awkwardly with a displeased expression.

No matter what she did, she struggled desperately to force my cock inside her pussy. Each attempt twisted her face in pain, but as time passed, her expression gradually softened, tinged with a glimmer of happiness.

With her plump chest, slender waist, and wide hips, she pressed down on my lower body without restraint.

The supple flesh of her pale thighs and her stockings clung heavily to my thighs. Meanwhile, the increasingly hot, slippery folds of her inner walls enveloped the head of my cock.

"Haa..."

Park Ha-rin straddled my lower body, her eyelashes fluttering faintly. Her expression was utterly desirable—no, completely consumed by lust.

"Hng... So big..."

Her golden eyes wavered in confusion at the sensation of penetration. My massive cock was pushing into her most sacred depths.

Squelch—

"Hngh... Haah... Si-hyun. Ugh."

She seemed to be enduring the pain of her hymen breaking, but her lust-filled face eventually crumbled.

"Kkh—!?"

The moment she wrapped her arms around me, her silver hair cascaded down, tickling my thighs. Her voluptuous body trembled slightly against mine.

Finally, she braced herself and lowered her hips with force.

"Aahk..."

Her virgin hole was unbearably tight, making it nearly impossible to take my oversized cock. Yet, little by little, her labia stretched as she forced it in.

Squelch—

Watching my cock disappear inside her, my mental state began teetering dangerously. Even before the tip reached her womb, the folds at her entrance wrapped around me so tightly I thought I might cum.

Gasping for breath, I forced myself to sound as composed as possible.

"Hah, hah... S-Sis, your virgin pussy must be trash. It's not going in well."

Park Ha-rin, bleeding from her crotch, suddenly laughed and pinched my cheek.

"Did you learn that from Uptomy too?"

"...."

What? How did she know?

"But since it's me, I'll play along♡"

The moment she said that, her eyes overflowed with childlike, pure joy. Yet that purity twisted into something darker—a love just as pure as it was depraved.

-♡

Park Ha-rin's face was dripping with lewdness, but I couldn't speak. Before I could even think, she slammed her hips down.

Plunge!

"Ugh...!"

Park Ha-rin bit her lip, her eyelids twitching.

My cock was buried deep inside her pink labia. Just a little more—just a little more, and I'd tear through my sister's hymen. No, maybe it was already slightly torn.

Virgin blood trickled down my shaft. But it wasn't enough. I wasn't satisfied yet.

I hadn't yet reached the deepest folds of her pussy.

"Noona, you're not seriously calling this sex, are you?"

Her gaze turned icy as it locked onto me. On the surface, she was trying to remain composed, but the unique shame of a virgin was impossible to hide completely.

"Let me teach you, as your senior in sex."

Her elegant brows furrowed as she sensed the unexpected ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠shift in the atmosphere. But it was already too late.

It had only just been completed.

[Skill 「Dream Realization」 has created the skill 「Female Submission」.]

The overpowered skill I'd been longing for.

[Optimal Progression is being applied.]

[「Censored Ability」 is intervening.]

[Judged insufficient compared to desire.]

[Skill 「Female Submission」 has evolved into 「Female Corruption」.]

I hadn't expected an upgrade, but at least it was stronger now.

[「Park Ha-rin」 has been branded with a 「Lewd Crest」.]

Finally, disbelief flashed vividly in her eyes.

"!"

A lewd tattoo had formed inside Noona's womb—what was known in the underworld as a succubus crest, or a Lewd Crest.

[Unique Job Skill 「Half-Spirit Body」 is being applied.]

[Can pass through objects or walls at will.]

Threads of mana wove through my body, grasping at the air meaninglessly.

Her face froze in shock.

She reached out to grab me, but her hand passed right through my face, her attempt ending in failure. In that moment, a flustered Park Ha-rin's face came dangerously close to mine.

"Noona. You don't call it sex until you go this deep!"

I shouted as I thrust my hips upward with force. Ha-rin's eyes widened at an astonishing speed, and my cock delivered a massive shock to her groin.

"Kkhhaaang?!"

My monstrous dick stretched her pink pussy to its absolute limit.

Noona's cunt expanded to match the size of my girth, convulsing as it was forced open. Every single fold inside her was scraped raw by my cock.

"Nngh...?!"

...My dick tore through the scorching walls of her pussy, burying itself all the way to her cervix. Then, belatedly—

"!?"

The fragile hymen that had barely held on was mercilessly torn apart. The proof of Noona's purity splattered between our thighs.

"Aahh—hhaaahh—iiit?!"

Her eyes lost all composure, shaking violently from the pain of violation. Her thighs were spread obscenely wide, the agony of her hymen being pierced without a trace.

The excruciating pain of her pussy being stretched wide sent Noona into convulsions of shock.

The base of my cock, momentarily pulled out of her body, was stained red with her virgin blood.

Thrust!

But I plunged back in, disappearing deep inside Noona's cunt once more.

"Hhaaaang?!"

"Noona just graduated from being a virgin. Congrats!"

"Nngh, kkhh—B-Bak Si-hyun...! Y-You, ah—haaahh—!"

Park Ha-rin could only sob as she clung to me, her body trembling intermittently.

"I-It... h-hurts..."

Her lips were tightly bitten, her eyes glaring at me with fury and humiliation. She must have never experienced pain like this before.

With her overwhelmingly superior physical abilities, she'd never had a reason to.

"Tch."

As a result, delicate tears welled up at the corners of her eyes before spilling over.

I had just shattered the hymen of the most extraordinary Noona in the world. The weight of that sin made her forget how to move. But right now, all that existed in front of me was a single female.

[Unique Job Skill 「Mind of the Strange Sage」 has activated.]

[Perceives all things without prejudice.]

There was no trace of morality left in me.

"Noona, how's your first cock?"

"......"

Park Ha-rin's white brows trembled as she scowled. She'd probably planned to play with me as she pleased and then break me in.

But what could she do now? I was the type who paid back what I was given—doubled.

"Noona, I asked you. How does it feel to become a woman on your little brother's dick?"

I roughly grabbed Ha-rin's heaving breasts with one hand. The other seized her stockings, which ran all the way up to her thighs, and her hips. I even squeezed her plump ass before yanking her panties upward.

"Kkhheuk?!"

Park Ha-rin's eyelids trembled with humiliation, but her pussy clenched tightly around me. The scorching folds of her cunt, slick with arousal, clung to my cock without a single gap. The panties rubbing against her asshole only further stimulated her.

"Hhhuuaang..."

She desperately bit her lip, but her heated body was already too busy letting out obscene moans. The composed expression she always wore was beginning to crumble.

Staring into Ha-rin's widened eyes, I lost myself in thought.

'Damn, there were no sex-related skills in the game, but I never thought I could create them like this. Dream Realization. It's even more broken ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠than I expected.'

『Skill: 「Female Corruption (Mythic Grade)」』

"Hahk, haa... s-stop...!"

My sister trembled, her lips quivering under the onslaught of pleasure. Her face was frantic, as if she couldn't gather her thoughts.

"P-pull out...!"

Tears and drool spilled from her as she tried to push me away.

But I wasn't the type to leave things unfinished. And a man isn't satisfied until he cums.

I pulled my hips back slightly, still pressed tight against her ass.

"Hngk...?"

My thick cock slid out of her dripping pussy with a wet sound, still glistening with her juices. The swollen lips clung desperately, leaving no gap as a mix of blood and slick spilled out.

"Ahhk, haaang...! Hahh...!"

Only the tip remained inside as I twitched, then plunged back into her virgin-tight cunt, now flushed red and leaking with her own arousal.

"See? You should've just left me alone!"

Thrust! Thrust!

Anger and lust drove me to piston into her like a beast. Her waist couldn't resist, swept away helplessly as her ass jiggled violently with each slam.

"Ngh, hhk! Uuuhh... haaang... hahh...!"

I violated every inch of her—her walls, her cervix, the deepest parts of her pussy. The way her entrance spasmed around my tip made me feel like I was about to burst.

By nature, a heroine's body was made for me. So of course, her pussy molded perfectly around my cock, clamping down as her juices gushed around me.

"W-wait...! No, no...! Hngghhaaahh!"

Park Ha-rin's eyes welled up as pleasure overwhelmed her. Her face twisted, losing all composure. But mercy wasn't something she could beg for now.

I locked her hips in place, ensuring she couldn't escape, then buried my cock to the hilt in a single brutal thrust. Her pussy stretched obscenely, taking my full length as if being reshaped by it.

"Guhhk, kkhh?! Aaahh! Park Si-hyun...! Stooop!"

She thrashed with every plunge, her body writhing in pleasure. But the sensations were beyond anything she imagined—her face twisted into that of a bitch in heat, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠drowning in both ecstasy and terror.

"Hahk, hhhh... haaahh...!"

Her glazed eyes rolled back as shock overtook her.

"Khuhk?! Ahhk?! Hhhhk!?"

Any trace of dignity was gone. With each thrust, her eyes threatened to disappear into her skull, her expression ruined beyond recognition.

Thrust! Thrust!

I kept her sweat-slick body pinned, defiling her insides relentlessly.

"Hahk, hahh... hahh...?"

The sound of flesh slapping echoed through the room as my thighs hammered against her ass.

"Uuuhhp!"

Her lips were sealed under mine, only choked whimpers escaping her throat.

Squelch. Squelch.

The lewd sounds of our joining filled the air, but Ha-rin, reduced to nothing more than a cock sleeve, couldn't even process them.

"Hhhooohk!"

Buzz—

Thrust! Thrust!

Because deep inside her, the Lewd Crest was glowing madly, amplifying her pleasure beyond reason.

『「Lewd Crest」 maximizes Park Ha-rin's pleasure.』

My cock showed no mercy, stretching her pussy to its absolute limit. Her inner walls convulsed violently, clamping down with each withdrawal before being brutally spread open again.

"Hahhh, ahhk...! T-too deep...! S-stop, i-it hurts...! T-too rough...! Nngh, aahh...! Si-hyun...! P-please...! Sis...! I-it's dangerous...!"

She was nothing but a panting bitch now, completely conquered by pleasure.

Her empty eyes shook desperately, begging for reprieve, but I didn't stop fucking her.

"Sis, I'm gonna cum in your womb. Take it."

"Wai—"

I didn't listen.

I just gripped her ass and slammed my twitching cock straight into her cervix.

Her eyes flew wide as her womb was violated, arms clutching me in panic before she was hurled over the edge—screaming.

"KHHHAAAAAAHHHK?!"

And then, I emptied myself inside her.

Splurt! Splurt!

Her pussy convulsed wildly, greedily swallowing every drop as my cum flooded her womb. The sensation of my release pumping deep into her was obscenely vivid.

And then, as the last spurts left me, rationality finally returned.

The next moment—

"...The fuck...?"

Her eyes rolled back completely as she spasmed in my arms, utterly broken.

"Hhh... haaeeehh...!"

Her once-elegant face was a mess, mouth slack and drooling. Tears streamed down her flushed cheeks as her pupils trembled.

And then—

Squelch.

Her pussy gushed, fluids spilling out in a lewd, shameful flood.
