The Insensitive Mage, Lee Hae-su (6)
The Insensitive Wizard Lee Haesu (Part 6)
Another perfect defeat.
My breathing grew rougher and rougher, and the Succubus's body trembled, unable to withstand the pleasure.
The humiliation from a week ago, when I alone swayed my hips atop his thick legs. That wretched nightmare of 'self-gratification' was about to repeat itself.
'This is insane... It was an anatomically perfect point. And it still didn't work? What the hell am I supposed to do then?!'
At that moment, a red System Window flickered ominously before my eyes.
[You must consume high-concentration Demonic Power (Vital Essence) within the deadline!]
A chilling shiver ran down my spine.
One week.
If I can't make this ice-block of a man's pillar stand and extract the Vital Essence from within him in one week, I'll surely wither and die.
'There's no time. If I back down here, it's over. I have no time to find another guy, no chance to try and conquer this bastard again!'
In my panicked mind, a passage from <Human Nervous System Anatomy>, which I had read all night in the library, flashed like lightning.
[Among the male body's parts, the absolute core that elicits the most primal and explosive neural response, regardless of pleasure or pain, is the prostate, and the only external pathway to directly stimulate it is the anus.]
Instantly, I held my breath.
The ego that was once male screamed.
'Crazy, even so... it might not work, right? And...'
This was a matter of pride.
Let's say I somehow rationalized transforming into a woman and swaying my hips on top of a man under the pretext of 'survival.'
But caressing a man's 'there' was accompanied by a terrible shame that scraped the very bottom of my soul.
However.
My gaze fell upon the arrogant face of Librarian Lee Hae-su, who was indifferently trying to organize his documents.
That arrogant and insolent attitude, not even sparing me a glance despite my desperate attempts to seduce him.
That damn look, treating me like nothing more than a beast in heat.
'...Fine, it's better than dying.'
More than anything, the fierce stubbornness to witness that arrogant Numb Mage lose his reason and pant like an animal beneath my feet completely severed my rationality.
Petty pride? To hell with it.
I am a hungry Succubus struggling to survive right now.
"...It's not over yet."
"Hmm?"
As I glared at him with eyes that seemed to devour him and muttered, Lee Hae-su's gaze turned to me, filled with question.
Instead of getting up, I reached out and firmly grabbed the collar of his neat shirt and his tie.
"Monotonous physical attacks don't work, you say? That he adapts to them?"
"What are you... Ugh!"
Thud!
With the Succubus's unique superhuman strength, I forcefully pushed him backward from his chair.
Even if magic didn't work on him, he was ultimately just a scholar unaccustomed to pure physical combat.
Helplessly pulled by my strong grip, he crashed roughly onto the wide desk.
Swish!
The neatly stacked bundles of documents on the desk scattered everywhere and fell to the floor.
Librarian Lee Hae-su, whose back was instantly pressed against the desk as he lay flat, had his eyes waver with bewilderment for the first time.
"W-What kind of... violent act is this?"
"Be quiet. To make you feel something, this measly chair won't give me the right angle."
I climbed onto the desk and forcibly spread his legs apart as he lay there.
Then, I grabbed the backs of his knees with both hands, letting his legs dangle loosely over the edge of the desk.
Two thick legs, spread wide in an M-shape.
Between them, his defenseless groin, with its zipper already down, and the path to the most intimate mucous membrane, hidden by his pants, was perfectly exposed.
This bizarre and lewd scene, where I had laid a man down and spread his legs, was something I couldn't have even imagined before.
I settled myself completely between his widely spread legs, at the edge of the desk.
Shame, depravity, and a fierce determination to conquer that man somehow mixed, making my eyes gleam with a reddish light.
"Then... what happens if I simultaneously strike and shatter five vital points of the human body, without giving his brain a chance to adapt...?"
I cast the man's last shred of rationality into the trash, then wetly licked my red lips with my tongue.
"Let's find out for ourselves."
The essence of human anatomy, and the dirtiest, most fatal special move, forged by a week of training.
The sequence of the [Five-Point Simultaneous Nerve Strike] finally lifted its veil.
Lee Hae-su lay roughly on the desk, his legs spread wide in an M-shape.
His always-neat shirt was crumpled, and his defenseless lower body was starkly exposed beneath my gaze.
"Now... what exactly are you trying to do?"
For the first time, a sense of alarm crept into his voice.
Even if his Demonic Power was blocked and his senses numbed, the situation itself—a robust man forcibly laid down by a Female Student with his legs spread—would have been enough to trigger an instinctive alarm.
But I didn't answer. No, I had no time to answer.
A countdown to my life.
And the hungry instincts of a Succubus who had completely abandoned her pride began to dominate my entire body.
Still sitting at the edge of the desk, I plunged my head between his legs without hesitation.
At the same time, I pulled the trigger on the [Five-Point Simultaneous Nerve Strike] that I had prepared for a week, practically spitting blood.
Crack!
First, my hands tore open the front of his shirt like a beast.
[First and second strikes.]
Buttons flew everywhere, revealing his firm pectoral muscles.
I simultaneously raked my fingernails down both nipples, where sensory receptors were most concentrated, and the surrounding nerve bundles, persistently twisting and kneading them.
"...!"
Lee Hae-su's brows furrowed sharply.
At the same time, my red Tail, which had been waiting in the air, burrowed into his underwear.
[Third strike.]
The hottest, stickiest mucous membrane on the inside of my Tail tightly wrapped around his central pillar, which was still lifeless.
Then, it began to frantically scrape at his corpus cavernosum, generating micro-vibrations I had mastered through a week of arduous practice.
But this alone wasn't enough.
I couldn't give his brain a chance to adapt.
I gripped the insides of his spread thighs with both hands, then opened my mouth.
[Fourth strike.]
"Slurp... Chup, lick...!"
My tongue, drenched in saliva, directly penetrated the man's most intimate spot, past the perineum, and into the wrinkled mucous membrane of his anus.
The rationality that was once male screamed, 'I'm licking a man's ass!' but the Succubus's body, on the contrary, trembled madly with the depravity of violating that taboo.
The core of the nerves leading to the prostate.
Even a body impervious to magic, the absolute vital point that anatomically would make a human brain recoil in horror, was wetly churned and sucked by my sweet tongue.
The final [fifth strike.]
My thoroughly wet thighs, dripping with arousal fluid, strongly entwined his calves and ankles, pouring physical pressure and the Succubus's body heat onto him.
My hands churned the nerves of his chest.
My Tail stimulated his central pillar like a vibrator.
My tongue licked up his anus as if to swallow it whole, simultaneously.
And my entire body's warmth and mucous membranes sealed off his lower body.
Five overwhelming physical stimuli struck his nervous system simultaneously, without a 0.1-second error, to the point where his brain couldn't even discern whether it was pleasure or pain.
And then.
A sound of a terrible crack finally echoed from the absolute ice wall that had seemed eternal.
"C-Ugh... Ah, ughh...!"
Librarian Lee Hae-su, who always boasted a 0 BPM change, suddenly gasped for breath.
His large hand hovered in the air before unconsciously gripping my silver hair roughly.
The sensory barrier, which he had blocked with magic, crumbled helplessly before a pure 'anatomical physical bombardment' that contained not a single degree of Demonic Power.
Thump, thump, thump!
Beyond my tongue and lips, I felt his pulse throbbing as if it would burst.
Most importantly, the most definite 'result' was within my Tail.
Throb!
A chilling sensation of veins rising.
His central pillar, which had been boasting a 0% expansion rate and hanging limp like a rubber stick just moments ago, began to swell monstrously, engorging with blood as if it would tear my Tail apart.
"Haa... Hmph."
As I pulled away my lips and lifted my head, an unbelievable sight unfolded before my eyes.
What burst forth as if to rip his underwear was of a monstrous and enormous size, utterly unbelievable for a bookish scholar.
A thick pillar, fully aroused with prominent blue veins, throbbed and stiffly lifted its head towards the air.
Pulse skyrocketing. Irregular breathing.
And, corpus cavernosum expansion rate of 120%.
"Haa... Hah, haa..."
I looked up at Lee Hae-su, who was gasping for breath, clutching his hair.
Dominated by the explosive sensations that erupted simultaneously from his anus, pillar, and chest, his usual cool and arrogant expression was utterly distorted by lust.
I casually wiped the saliva from the corner of my mouth with the back of my hand, then flashed the most seductive and arrogant smile in the world.
"How's that?"
As my Tail firmly gripped and slid down his stiff, enormous pillar once, his back arched like a bowstring on the desk.
"Pulse not normal. Breathing irregular. Blood flow exploding. And..."
I pushed myself up and brought my wet, soaked groin directly over his massive weapon.
"Corpus cavernosum expansion rate, perfect."
[Condition met! The target's Demonic Power has been maximized!]
[Begin consuming Demonic Power (Vital Essence)!]
