Called Her for Sex During Class
Ninety-five points. The same score as Seol noona. With just a little more practice, she seemed ready to surpass her.
It wasn't that Seol noona couldn't do it. Nari simply had an insane talent for blowjobs.
"I don't really have any feedback to give."
I shook my head with a smile. Even if I tried to find something to improve, my experience with cocks so far wasn't enough to spot any flaws.
The texture of her tongue, the precision of her technique, even her ability to read my reactions—everything was perfect.
"If I had to say something, it's that you're already perfect, but I'm looking forward to seeing how you develop even further from here."
At my praise, Nari smiled faintly. That expression carried the quiet confidence of someone who believed this level of skill was only natural. I found myself wondering just how good her blowjobs would become if she improved even more.
She lightly licked away the traces of the blowjob still clinging to the corner of her mouth.
"But how did you get this good at giving head? Did you practice ahead of time?"
"My mom has a long tongue too, so she was always great at blowjobs. She said Dad doted on her for it, so she taught me how to use my tongue."
Nari answered as if it were nothing. If anything, she almost seemed proud of her mother.
A mother who passed down blowjob techniques to her daughter so she could be loved by her husband. I marveled once again at how completely insane this world had become.
The lewd thought even crossed my mind that if I ever got the chance to meet Nari's mother later, I might want to experience her tongue skills for myself.
After that I received blowjob practice from the other female students as well, but none of them came close to Nari's level.
Once the blowjob practice session ended, fourth period began.
"Fourth period is deepthroat training."
Seol noona started explaining from the podium.
"The first goal is learning to control your breathing. You have to minimize the foreign-body sensation and the choking feeling in your throat while securing space to take the cock."
She brought up a cross-section diagram of a human throat on the screen. Her laser pointer moved across the sharp illustration.
"The most important thing is controlling the gag reflex. From now on we'll begin systematic desensitization training."
"Use the training tools to gradually stimulate your throat deeper and deeper. This is the process of steadily raising the threshold at which the reflex kicks in."
When Seol noona finished her explanation and everyone started practicing, gagging sounds erupted from all around the classroom.
"Push the teaching aid deep into your mouth. Absolutely do not bite down with your teeth."
"Uwek!"
"Kek, kek… cough!"
The female students each scrunched up their faces and began thrusting the training tools into their own throats.
Watching them desperately fight back the urge to vomit while tears beaded in their eyes left me with a strange feeling.
It was almost touching, seeing them put in this much effort just so they could deepthroat properly.
"However, some men actually want the gag reflex, so after you've completely eliminated it you'll also need to practice triggering it on purpose."
At Seol noona's words, a few of the female students tilted their heads.
So there were men who wanted to watch a woman gag and retch. Interesting.
"Next is breathing technique. Master diaphragmatic breathing so you can relax your body and loosen the muscles in your throat."
The women each began taking deep, slow breaths exactly as Seol noona instructed. A strange calm settled over the classroom.
"Because this practice carries high risk, I'll only demonstrate it myself. If someone bites down on a cock from the gag reflex, it would be a disaster. Everyone, practice thoroughly with the teaching aids at home."
"The goal is to be able to start sucking immediately even if a cock is shoved down your throat while you're asleep. Tomorrow, anyone who has perfected their deepthroat practice will get the chance to practice directly on Model Sihyuk."
When Seol noona finished speaking, I saw Nari give a small smile from the corner.
It was clearly the expression of someone who had already mastered deepthroating.
She must have practiced at home with something like a cucumber after learning from her mother.
"Alright, then I'll begin the demonstration."
Seol noona knelt in front of me once more. A different kind of resolve settled on her face. Even she seemed a little nervous about deepthroating.
After taking a few deep breaths, she took my cock into her mouth.
Then she slowly began to swallow it.
"Uup…."
The moment the head of my cock pushed past her throat, Seol noona's brow furrowed slightly.
I could feel with vivid clarity the sensation of my cock forcing its way into her throat. Completely different from a regular blowjob—her narrow, hot esophagus clamped tightly around the head of my cock.
But she didn't stop. Instead she steadied her breathing and took me even deeper.
Everyone in the classroom watched the scene with bated breath.
The sight of a woman enduring pain to swallow my cock. Those submissive eyes looking up at me with tears faintly welling up.
For a moment I felt a flicker of sadism and a sense of conquest.
Finally, when my cock was almost completely buried, Seol noona showed off a new technique—tightening the muscles of her throat.
"Oh…?!"
The warmth and the clenching of her throat around the head of my cock made a moan slip out of me before I could stop it.
The visual satisfaction was far greater than I had expected.
How should I put it—it was even hotter because it felt like her mouth had become a custom case for my cock.
"Churp, jyuup, chup, heu, heu…."
Seol noona's breath stirred the hair at the base of my cock.
In that position she began moving her head back and forth, deepthroating me, and the urge to cum slowly rose.
The soft flesh deep inside her throat writhed and caressed the head of my cock.
I wanted to finish just like that, but her expression looked too strained, so I held back.
No matter how much she had practiced with dildos, taking my huge living cock had to feel completely different.
And on top of that she was tense because if she accidentally bit down it would be a disaster.
I gently stroked Seol noona's head.
"That's enough. You did well."
At my quiet whisper, she smiled in relief and pulled off my cock.
"Everyone, practice so that you can perform deepthroat practice by tomorrow."
With that, morning classes ended and it became lunchtime.
I ate quickly and chatted with the girls in my class about the blowjob techniques we had learned today. While giving feedback to everyone, I also learned that the other classes weren't covering deepthroating at all.
Probably because ordinary men's cocks weren't big enough to need deepthroating.
I also learned about a new academy rule.
If a man called for her, a female student was allowed to skip her major classes.
Far from any penalty, if she missed class because a man had summoned her, she even received bonus points.
So during afternoon major classes, I called a girl to the sexual processing room.
I was waiting inside the sexual processing room when the door soon opened and someone entered.
It was Lee Nari.
Just being summoned by a man was enough that she couldn't hide the joy on her face.
"You called for me, Sihyuk-nim?"
I sat on the edge of the bed and patted the spot beside me.
Nari approached without hesitation and sat next to me.
The bed dipped slightly under her weight.
Her black mini dress stood out sharply against her white skin.
"Do you know why I called you?"
I asked playfully. Nari looked at me with eyes full of anticipation and answered politely.
"Is it because you want sexual processing with my blowjob?"
"Half right."
I grinned and gently lifted her chin.
"Have you practiced kissing?"
"Yes. I practiced with Mom every day."
I was momentarily flustered by the completely unexpected answer. Kissing practice with her mom?
Mother and daughter kissing and mixing tongues every single day for practice?
"Ahem, is that so? Well, uh. Anyway, then kiss me."
I parted my lips slightly. It was a provocation half-playful and half pure curiosity about her skill.
A bright smile bloomed across Nari's face.
"Yes, Sihyuk-nim. Just leave it to me."
Nari's face slowly drew closer. Maybe because I was looking forward to kissing a girl, her movement felt like slow motion.
Even though I had had sex several times, as a former virgin I still found kissing incredibly thrilling and nerve-wracking.
The first thing that captivated me was the visual. Under the bright lights, the shadows cast by her long eyelashes trembled faintly across her smooth cheeks.
I could see anticipation and a faint nervousness swirling in her pale black eyes.
Her cherry-red, plump lips were slightly parted, offering a glimpse of the moist interior of her mouth. She looked like a pomegranate so ripe its juice was about to burst.
And there was a scent. Not some cheap artificial perfume, of course.
The subtle shampoo fragrance from Nari's hair, the clean scent of her skin, and her own sweet body odor that wrapped around everything else all mingled together and tickled the tip of my nose.
Just before her lips met mine—at a distance of less than a centimeter—she paused for a moment.
Her hot breath brushed against my lips. Mixed faintly into that breath was the fresh scent of orange juice she must have drunk just earlier.
Chup.
At last those lips touched mine.
Soft, plush, and warm. Even though at first they only pressed lightly together, it felt as if her heartbeat was being transmitted through our lips.
I closed my eyes and fully savored that first sensation.
Then, as if she had been waiting for exactly this, Nari gently bit and released my lower lip, signaling the true start of the kiss.
"Mmm…."
A low moan slipped out of me unbidden. Encouraged by my reaction, she began softly sucking my upper and lower lips in turn, the way a newborn suckles.
Small wet sounds—chup, chup—echoed lewdly through the quiet room.
Whether she really had practiced kissing with her mother every day or not, Nari's lips moved with technical skill.
She didn't just suck; she also rubbed the soft inner flesh of her lips against mine as if massaging them, and sometimes gently tugged to create tension.
Every one of those delicate movements was awakening every nerve in my lips.
After thoroughly teasing my lips, Nari finally began moving her tongue.
The tip of her long tongue carefully parted my firmly closed lips and slipped inside.
That was when it truly began.
Without relying solely on her natural gift of tongue length, the tongue technique Nari had honed through daily practice was incredible.
At first it was incredibly gentle. She wrapped my tongue with her own and soothed and coaxed it as if dancing.
Then suddenly she scraped the roof of my mouth with the tip of her tongue. My body jerked from the unexpected stimulation.
"Ung, chuk, churp, chuk, haup…."
The wet, messy sounds of Nari kissing filled the room.
Her tongue never stopped. It swept every corner of my gums and relentlessly probed even behind my molars.
It was as if she were determined to find every hidden pleasure switch inside my mouth.
At first I was completely swept away by her dazzling lead. But as I gradually grew used to it, I wanted to take the lead myself.
So I wrapped one hand around the back of Nari's neck and pulled her firmly toward me.
Then I shoved my tongue in far more roughly than before. It was clumsier than the kiss she had given me, but today I wanted to kiss her this violently.
"Eup…!"
Startled, she momentarily hesitated over how to move her tongue. Ignoring that, I explored her mouth.
Exactly as she had done to me—no, even more. I pressed her tongue down with mine and licked the soft flesh inside her mouth.
Our kiss grew steadily more intense. We mixed tongues and swallowed each other's saliva, forgetting even to breathe.
Our lips had already grown so hot from how long we had been locked together that if we kept kissing they would probably swell.
While we frantically mixed tongues, I took Nari's hand that was resting on the bed and placed it on my thigh.
I knew it was an obvious perverted move, but I didn't care.
Nari immediately understood my intention, smiled with her eyes, and gently stroked the bulging outline of my cock over my pants.
Paha—at last the long kiss ended. We faced each other, panting hard.
Her eyes were completely unfocused with pleasure, and her lips glistened with my saliva.
"Sihyuk-nim."
Nari called to me as if asking permission for a moment.
"Would it be alright if I licked your body a little?"
"As much as you want."
The moment I gave permission, Nari began licking my ear and neck as if she had been waiting for it.
The ticklish yet scorching sensation of her hot breath against my skin was incredible. For a long while she licked my body and teased me.
Finally I brought up the main subject.
"Continue what we were doing in class earlier."
I pointed at my cock and ordered.
"Start the blowjob."
