The Insensitive Mage Lee Haesu (4)
The Numb Mage Lee Hae-su (4)
I didn't back down and focused my consciousness to my fingertips.
I raised the magical power I had stolen from the Health Teacher to its limit and activated my dark attribute magic.
Two pitch-black tentacles extending from my shadow.
They surged through the air like snakes, shooting toward Librarian Hae-su's wrists as if to bind them.
I was determined to restrain him by force, to shove the magical power within me into his circuits and forcibly elicit a reaction.
Chae-ang-!
But just before the tentacles touched his wrists, they shattered into fragments of black magical energy with a sharp cracking sound, as if they had hit an invisible, thick glass wall.
[Warning! The target's Magic Circuit is completely 'closed'.]
[All magical interference and penetration is nullified.]
"......No way."
I looked back and forth between the system window floating in the air and him, unable to believe it.
The magical power couldn't even penetrate.
This wasn't just a simple defensive magic.
It meant his body itself was an 'absolute void space' that perfectly repelled all external stimuli and energy.
"Are you finished?"
Professor Hae-su pushed his glasses up with his middle finger and rose from his seat.
I hadn't realized while he was sitting, but standing up, he was clearly over 185 cm tall with broad shoulders.
With my shrunken, slender succubus body, now barely over 160 cm, I had to endure the full force of his intimidating downward gaze.
He strode toward me.
I instinctively stepped back but soon felt my back hit the cold wall.
"I didn't expel you and observed you because you were a rare succubus test subject, but you keep crossing the line."
He grabbed my chin with his large hand and lifted it, my back against the wall.
His fingers were cool as ice.
But my body was already trembling lewdly in reaction to that small contact.
"You said you'd awaken my senses? Fine. If you want it that badly, keep trying."
His obsidian eyes seemed to flash for the first time.
But it wasn't lust. It was the look of intense intellectual curiosity and a cold-hearted researcher.
"However, the deadline is the end of this semester. If you can make me feel even 1% of sensation, I'll give you the reward you want."
He brought his lips close to my ear.
As his cold breath brushed against the fine hairs, I barely managed to keep my legs from giving way.
"But, if you fail."
His voice slid into my ear like a cold snake.
"I will dissect every secret of your unique succubus body and dark magic on my operating table. Academy regulations hold no power within my lab."
"......!!"
A chill ran down my spine.
This man wasn't joking.
Not being able to feel physical sensations might mean he also lacked empathy or moral guilt toward others.
'What kind of monster have I provoked?'
The right thing to do was to scream 'I give up on the assignment!' and run away right now.
But.
My insane succubus instinct, even in the face of this absolute terror and pressure, was igniting a thrilling heat from deep within my stomach.
This absolute iceberg that seemed utterly unconquerable.
The imagination of this man crumbling because of me, swept up in a sensory frenzy, begging for pleasure with tears in his eyes beneath me.
That immoral fantasy was drenching my lower body uncontrollably, as if mocking my male ego.
"......Alright."
I grinned with my chin still in his grip.
Staring straight at him with red eyes mixed with fear and excitement.
"I accept that bet."
"......"
"I'll make the Librarian-nim beg for his life beneath me, crying and pleading for me to touch him just one more time."
Even after my bold declaration, Librarian Hae-su's gaze remained calm like a still lake.
He released my chin and returned to his seat as if nothing had happened.
"I look forward to it. But empty words are meaningless."
That dry attitude only madly provoked the stubbornness of the man 'Lee Jeong-hoon' within me.
'Magic doesn't work? Then I just won't use magic!'
True damage that penetrates defense.
In other words, **'pure physical contact'**.
He said he couldn't perceive physical impact, temperature, or even the sensation of mucous membranes.
But as long as he has a human body, unless his sensory receptors are completely annihilated, his brain would have to react unconsciously to extremely intense and primal stimuli.
And right now, I had one weapon more lethal than any magic.
This damn sensitive and perverse 'succubus body' itself.
"Well then, shall we begin the first attempt right away?"
I kicked off my shoes and stepped barefoot on the cold floor, approaching like a cat.
Without making a sound, I approached behind his back, without hesitation placed my hands on the arms of his chair and spread my legs.
And then I hopped right onto his firm knees.
"......"
The narrow space between the desk and his torso.
As I mounted him, pressing my whole body against him and weighing down on his thighs, his gaze shifted from the documents to me.
Even with a female student suddenly on his lap, his heartbeat and breathing didn't fluctuate even 1 BPM.
I completely excluded magical power.
Instead, I heated my body to the utmost, pushing the purest physical heat and sweet body odor a succubus could emit right under his nose.
Slither-
The red heart-shaped tail that popped out from under my skirt wrapped around his waist like a snake.
"Euk..."
The sensitive mucous membrane on the inside of my tail brushed against his firm thighs and groin through the fabric of his pants.
Instead, it was my body that shuddered with pleasure first.
This immoral sensation of stimulating a man with my tail, with the feeling transmitted directly to my brain.
I grabbed the collar of his shirt with both hands and pulled.
Then I lowered my head and pressed my lips tightly against his pale nape.
"Churup... Chup, eung..."
My tongue licked up his collarbone area.
A succubus's saliva was physically sticky and sweet even without mixing in magical power. I persistently sucked on his nape, gently bit with my teeth, and caressed the mark with my lips.
Every time the heavy two mounds of my chest rubbed against and crushed against his hard chest, I couldn't control my own sensations and let out sweet moans mixed with nasal sounds.
"Haa... Heut."
Above, my tongue lewdly ravaged his nape and earlobe.
Below, my tail constricted like a snake around his pants zipper area, applying steady pressure.
My damp groin was constantly creating friction heat on his thigh, drawing lewd trails without rest.
With this level of physical combat, even a eunuch should have blood rushing down there.
I even reached my hand onto his pants, blatantly grabbing and kneading the man's most secret and sensitive center.
But.
"......"
Five minutes passed, then ten.
My breathing became rough, my whole body was drenched in sweat and gushing love juice, panting heavily.
In contrast, Professor Hae-su beneath me just had his arms on the desk, observing me with the eyes of someone watching an interesting documentary.
Despite my hands and tail pouring such persistent caresses onto his lower body, it hadn't swollen up even 1 cm.
Perfect, and absolute, non-reaction.
"Haa... Heuk, haa......"
As I reached my physical limit and panted with my forehead resting on his shoulder,
Professor Hae-su pushed my waist away with an indifferent hand and spoke.
"Pulse normal, breathing normal, no change in blood flow. Lower abdominal corpus cavernosum expansion rate 0%."
He brushed my sweat-dampened silver hair behind my ear and spoke in an extremely dry voice.
"I appreciate the enthusiasm, but your strategy is pathetic. Did you think repeating crude friction would work just because magic doesn't?"
"......!!"
"What you just did didn't excite me. You just got yourself off on my leg while in heat."
Instantly, my face burned hot as if I'd been slapped.
He wasn't wrong.
The friction from my tail and mucous membrane meant to stimulate him had instead stimulated my sensitive succubus body, making me cross my legs and lose myself in sensation alone.
"Your stamina is lacking, your tail movements are monotonous, and your technique for caressing with mucous membranes is ridiculously childish. Did you boast about awakening my senses with that crude technique?"
He grabbed my waist with his large hands and lifted me up like a child, setting me down beside the desk.
"Return for today. Next time, I expect you to bring slightly more 'meaningful' data, both visually and physically."
A perfect and miserable counter.
I had no choice but to grab my shoes with trembling legs and flee the lab.
Slam-!
As soon as the lab door closed, I leaned against the corridor wall, slumped down, and clutched my head.
"Uwaaaaak!! So embarrassing! Damn it, I'm so embarrassed I could die!!"
