The Insensitive Mage Lee Haesu (5)
The Numb Mage Lee Hae-su (5)
The moment I returned to my dorm room, I rolled around on the bed and kicked the blanket away.
Just thinking about how I was the only one panting and twisting my waist on a man's lap made me want to bite my tongue in shame.
And that pathetic (?) result that didn't even rise 1cm.
'Come to think of it, it was obvious.'
Pulling the blanket over my head, I desperately clung to reason and began to analyze the situation.
I was originally a man. Lee Jeong-hoon, an ordinary guy in his 20s with no experience with women.
No matter how much I possessed the superior hardware of a Succubus, if my software (technique) was bottom-of-the-barrel, how was I supposed to conquer that stone-like Bul-gam Mage?
'I thought if I just roughly pushed and rubbed against him, the man would go crazy on his own. But that only works on normal guys, and my opponent is an invincible sand-nim whose senses are completely dead.'
I couldn't rely on the vague skills my body remembered.
Pure physicality and overwhelming technique. The strength of the tail, the flexibility of the pelvis, and a perfect anatomical understanding of what stimuli most effectively strike a man's brain were all necessary.

I shot up from the bed and immediately began planning a hellish training regimen to remodel my body into the ultimate 'seduction weapon'.
Starting the next day, my dorm room transformed into a bizarre and lewd training room.
"Hoo, hht! One, two, ugh, three...!"
The first was core and lower body training, namely 'Kegel exercises' and squats.
To tirelessly rotate my hips on Librarian Hae-su's firm thighs, overwhelming pelvic strength and stamina were essential.
I repeated squats, sweating profusely.

The problem was, damn it, the Succubus body was far too sensitive. Every time I tensed and relaxed my muscles, a tingling pleasure surged up between my legs.
"Aahng, hht... I'm going crazy. It's just a simple lower body workout, why is this happening...!"
My legs trembled and gushes of love juice poured out, soaking my underwear, but I gritted my teeth, suppressed the pleasure, and completed the reps.
The second was tail control training.
A Succubus's tail was like a third hand. But I still couldn't control this tail as I wished, limited to crude actions like simply rubbing a man's thigh as I did last time.
I set up a chair to act as a pillar in my room and practiced repeatedly picking up objects with my tail or tightly wrapping it around the pillar like a rope. I also honed a technique to create very subtle, irregular vibrations using the mucous membrane at the tip of my tail.
"Good, now it's moving quite naturally."
The tail drew a smooth S-shape in the air, slicing through the void with agility.
At this level, it should be fully capable of elegantly untying the professor's necktie and delving deep inside his pants to tease his weakness with finesse.
The last was 'theory'.
I borrowed thick academic books like <Human Neural Network Anatomy> and <The Structure of Magical Circuits> from the library and pored over them all night.
Where to press to get the biggest reaction from the sensory receptors. Which lymph nodes to stimulate to forcibly direct blood flow to the lower body. I analyzed the map of the male body all night long, mobilizing all my memories.
And so, a full week.
I devoted myself entirely to bizarre and perverse training aimed solely at conquering Librarian Hae-su.
The day of the decisive battle.
After showering and standing before the mirror, I could clearly feel the subtle changes that had occurred in my body.
Thanks to the daily pleasure-enduring squats and pelvic training, my hip and thigh lines had become much more elastic and devastatingly attractive than before.
The confused gaze that was once swayed by the Succubus's instinct was gone, replaced by the composure of a predator who had planned the perfect sequence to attack her target.
"It'll be different this time, Librarian-nim."
[Warning: You must intake magical energy within 7 days!]
Looking at the system window floating in the air, I smoothly curled up my red lips.
The crude act of simply rubbing and touching was over.
Strength, flexibility, the delicate control of my tail, and even knowledge of human anatomy. The ultimate finishing move to physically shatter the brain of an opponent immune to magic was complete.
Tonight.
A vicious malice flowed through my veins, determined to finally raise that ice-cold man's lower body and make him pant at my feet.
I left the room, wearing the very thin, tight black slip I had specially prepared for today underneath my uniform.
Late at night, in the librarian's personal study located in the deepest part of the library.
Click-
Along with the sound of the lock, I felt the cool touch of the iron door behind my back.
Professor Hae-su on the other side of the desk was flipping through documents in the exact same posture as a week ago.
That arrogant attitude of not even giving me a glance, even though he knew I had entered, even though he heard the door lock.
"Have you come again, unable to control your heat cycle."
An extremely dry voice reached me, his eyes still not leaving the documents.
But today, a relaxed smile hung on my lips. Instead of answering, I tore off the uniform jacket and blouse I was wearing, buttons and all, and dropped them on the floor with a thud.
Rustle-
The black slip hidden under the uniform revealed its provocative form.
Wearing that lewd scrap of fabric, so thin it seemed to cling to the skin, blatantly revealing the cleavage, pelvic line, and the curves of my buttocks, I approached him barefoot, stepping lightly.
"Today... there will be a very 'significant' change in your database, Librarian-nim."
Without hesitation, just like a week ago, I placed my hands on the arms of his chair and spread my legs. And then I hopped up onto his firm knees.
The angle of my pelvic entry was different from the crude and ignorant me of a week ago.
Precisely on the vital point where the lymph nodes and blood flow of his lower abdomen converged. I pressed the center of my buttocks firmly against the position in the male body where the nervous system had no choice but to react most sensitively.
And using the core strength honed by training, I began to press down heavily with my lower body and rotate my hips.
Slither-! My red heart-shaped tail, which had sprung out from under my skirt, moved with a speed and agility incomparable to before. Like a living snake, the tail instantly undid his pants buckle and pulled down the zipper.
"......Your movements have improved somewhat."
Despite my provocative actions, Hae-su still didn't bat an eyelid.
'It's more than just an improvement. Today, I'm going to completely shatter that invincible sand-nim cosplay of yours.'
Rubbing the sticky bodily fluids and scent emanating from my body against his lower abdomen, I began to bounce my pelvis in earnest.
The muscles around my entrance, trained to the extreme by Kegel exercises, wrapped around the man's solid thighs like a snake and tightened.
Simultaneously, I vibrated the mucous membrane at the tip of my tail subtly and persistently scraped down the root of the central pillar bulging under his underwear, inside the unzipped opening.
"Haang...! Ugh, haa, ang...!"
But ironically, it was from me that the heated moans burst forth.
The Succubus body was, damn it, far too sensitive. Every time I twisted my hips on the man's firm muscles, the friction of the tender mucous membrane between my legs sent pleasure intense enough to melt my brain rushing up my spine.
Squelch, squish-
Already, lewd love juice was trickling down his thighs in streams, darkening the fabric of his pants.
Lee Jeong-hoon's reason was still screaming in shame, 'Crazy, what the hell is this nonsense on a man's lap?', but the Succubus's body was instead madly enjoying this immoral act.
'It's okay. With this level of physical pressure and technique... No matter how much he's blocked his senses, the blood *has* to rush down...!'
Gasping for breath, I was confident of victory. The skill with which my tail violated his weakness was, even in my own eyes, artistic.
However.
"Increased range of motion in the pelvis. Utilizing the tail's mucous membrane for micro-vibration strikes. Certainly an improvement over last time's crude hip rubbing."
The voice of Librarian Hae-su, pinned beneath me, was as calm as before, without a single decibel of difference.
He raised one arm that had been resting on the desk and lightly gripped my chin, beaded with sweat.
In the eyes looking down at me, there wasn't a trace of lust. Only the cool gaze of a scholar observing an interesting lab rat.
"However, no change in blood flow rate. Cavernous body expansion rate in lower abdomen still 0%. Unfortunately, it's insufficient to surpass the threshold of my neural network."
"......!!"
A devastating feeling, as if I were sitting on a giant block of rubber.
His lower body was in a state of perfect non-reaction, not swelling even 1cm despite me throwing all sorts of crazy fits and pouring out love juice.
"Haa, hhk... Lies... Y-you feel nothing even like this...?"
"The human brain quickly adapts to sustained stimuli. The frictional heat and vibration you're applying to my lower abdomen aren't bad, but to me, it's merely the level of a 'slightly warm massager'."
Hae-su released my chin and gave my waist a light push.
"Your stamina seems to have already hit rock bottom. Get down now."
