I Called Her Over to Have Sex During Class

95 points. She was on par with Iseol noona. With just a little more practice, I felt she might surpass noona.

It wasn't that Iseol noona was incapable. Nari simply had an insane talent for fellatio.

“There’s not much to give feedback on.”

I shook my head with a smile. Even when I tried to find something lacking, I couldn't find anything given my current experience with cocks.

Everything was perfect, from the texture of her tongue and the precision of her technique to her ability to read my reactions.

“If I had to put it into words, I’d say you’re perfect already, but I’m looking forward to seeing how you improve on your own from here.”

At my praise, Nari gave a faint smile. Her expression held the confidence of someone thinking, ‘Of course I’m this good.’ I wondered how skilled she would become if she improved beyond her current level.

She lightly licked away the traces of fellatio around her lips.

“But how are you so good at fellatio? Did you study in advance?”

“My mother has a long tongue too, so she was good at fellatio. She said my father adored her, so I learned how to use my tongue from her.”

Nari answered casually. If anything, she seemed proud of her mother.

A mother who taught her daughter fellatio so she could be loved by her husband. I marveled at this insane world once again.

Perhaps, if I ever got the chance to meet Nari’s mother, I could experience her tongue techniques as well. The naughty thought briefly crossed my mind.

I received fellatio from the other female students afterward, but there was still no one as skilled as Nari.

Once all the fellatio practice was over, fourth period began.

“Fourth period is deep-throat training.”

Iseol noona began explaining from the podium.

“The first goal is to control your breathing. You need to minimize the foreign-body sensation and choking feeling in your throat while making room to accept a penis.”

Noona displayed a cross-sectional diagram of a human throat on the screen. Her laser pointer moved across the vivid image.

“The most important thing is controlling your gag reflex. From now on, we’ll begin systematic desensitization training.”

“Use the training aid to stimulate your throat gradually. The process involves slowly raising the threshold at which your reflex is triggered.”

Once noona finished explaining and everyone began practicing, the sounds of gagging erupted throughout the classroom.

“Put the training aid deep into your mouth. Under no circumstances should you bite down with your teeth.”

“Blegh!”

“Keh, keh… cough!”

The female university students each frowned and began thrusting the training aids into their throats.

Watching them desperately hold back their gags even as their eyes watered left me feeling strangely moved.

It was a little touching that they were trying so hard to give deep throat.

“However, some men want the gag reflex, too. Once you’ve completely eliminated your gag reflex, you must practice triggering it again instead.”

Several female university students tilted their heads at noona’s words.

So there were men who wanted to watch women gag.

“Next is breathing technique. Learn abdominal breathing, which relaxes your body and loosens your throat muscles.”

The women each began taking deep, slow breaths as noona instructed. A strange tranquility settled over the classroom.

“This practice carries a high risk, so I’ll only demonstrate it myself. It would be disastrous if you bit the penis because of your gag reflex. Practice sufficiently with the training aid at home.”

“The goal is to be able to suck it immediately even if a penis were lodged in your throat while you were asleep. Anyone who has perfected deep throat by tomorrow will get the opportunity to practice directly on Sihyeok, our model.”

When noona finished speaking, I saw Nari give a subtle smile from the corner of the classroom.

It must have been an expression of confidence that she had already mastered deep throat as well.

She must have learned it from her mother at home and practiced with something like a cucumber.

“All right, then. I’ll begin the demonstration.”

Iseol noona knelt before me again. Her expression held a solemn resolve unlike before. Even noona seemed a little nervous about deep throat.

Noona took several deep breaths before putting my cock in her mouth.

Then she slowly began swallowing my cock.

“Uuugh….”

The moment my glans passed through her throat, noona’s brow furrowed slightly.

I vividly felt my cock forcing its way into her throat. Unlike fellatio, her narrow, hot esophagus squeezed tightly around my glans.

But she didn’t stop. Instead, she steadied her breathing and accepted my cock even deeper.

Everyone in the classroom watched the scene in breathless silence.

The sight of a woman enduring pain as she swallowed my cock. Her submissive gaze as she looked up at me with tears slightly welling in her eyes.

For a moment, I felt a touch of sadism and a sense of conquest.

When my cock was finally almost all the way in, noona demonstrated a new technique. She tightened the muscles in her throat.

“Oh…?!”

The warmth around the glans lodged in her throat and the squeeze made a moan escape me before I realized it.

The visual satisfaction was incredible, far more than I had expected.

Somehow, it was even more arousing because her mouth felt like a case made for my cock.

“Slurp, schluurp, smack, hnn, hnn….”

Her breath stirred my pubic hair.

As she moved her head back and forth in that position, performing deep-throat fellatio, my urge to cum gradually built.

The soft flesh inside her throat writhed as it caressed my glans.

I wanted to cum right then and there, but noona looked so exhausted that I held back.

No matter how much she had practiced with a dildo, accepting my enormous, living cock must have felt like an entirely different experience.

And she had the added tension of knowing that it would be disastrous if she accidentally bit down.

I gently stroked noona’s head.

“That’s enough. You did well.”

At my soft whisper, noona smiled as though relieved and pulled my cock out.

“Practice so that everyone can perform deep throat by tomorrow.”

That brought the morning classes to an end, and lunchtime arrived.

I ate quickly and chatted with the girls in my class about the fellatio techniques we had learned that day. While giving everyone feedback, I learned that the other classes weren’t learning about deep throat.

It was probably because ordinary men’s cocks weren’t large enough for deep throat.

I also learned a new rule at the academy.

A female university student could skip her major class if a man called for her.

Rather than receiving a penalty, she even earned extra points if she skipped class because a man had called for her.

So, during my afternoon major class, I called a woman into the sexual-relief room.

I was waiting in the sexual-relief room when the door soon opened and someone entered.

It was Nari.

Nari’s expression couldn’t hide her joy at being called by a man.

“Did you call for me, Mr. Sihyeok?”

I sat on the bed and patted the spot beside me.

Nari approached without hesitation and sat beside me.

The bed dipped slightly under her weight.

Her black minidress stood out vividly against her pale skin.

“Do you know why I called you?”

I asked playfully. Nari looked at me with eager anticipation and answered politely.

“Did you want me to give you sexual relief with my fellatio?”

“Half right.”

I grinned and gently lifted her chin.

“Have you practiced kissing?”

“Yes. I’ve practiced with my mother every day.”

I was momentarily flustered by that completely unexpected answer. She practiced kissing with her mother?

Had a mother and daughter really kissed and practiced intertwining their tongues every day?

“Hmm, really? No, well… Anyway, then kiss me.”

I parted my lips slightly. It was a provocative challenge containing a touch of mischief and genuine curiosity about her skill.

A bright smile blossomed across Nari’s face.

“Yes, Mr. Sihyeok. Just trust me.”

Nari’s face slowly drew closer. Perhaps because I was anticipating kissing a woman, her movements seemed to unfold in slow motion.

Though I’d had sex several times, I’d never dated anyone, so kissing still made me incredibly excited and nervous.

The first thing to captivate me was the sight before me. Beneath the bright lights, the shadows cast by her long eyelashes trembled on her pale cheeks.

I could see anticipation and faint nervousness swirling in Nari’s dark eyes.

Her plump, cherry-red lips were slightly parted, offering a glimpse of the moist interior of her mouth. She looked like a ripe pomegranate just on the verge of bursting with juice.

Then there was her scent. It obviously wasn’t some cheap, artificial perfume.

The faint shampoo fragrance from Nari’s hair, the clean scent of her skin, and the sweet body fragrance unique to her all mingled together and tickled the tip of my nose.

Just before Nari’s lips touched mine, she paused in the brief distance of less than a centimeter between us.

Her hot breath brushed my lips. It carried the faint, refreshing scent of orange juice, as though she had just drunk some.

Smack.

At last, those lips touched mine.

They were plush, soft, and warm. At first, our lips merely met lightly, yet I felt as though I could sense her heartbeat through them.

I closed my eyes and savored that first sensation completely.

Then, as though she had been waiting for it, Nari gently bit my lower lip and released it, signaling the beginning of a real kiss.

“Mmm….”

A low moan escaped me before I realized it. Perhaps encouraged by my reaction, she began alternately sucking my upper and lower lips as softly as a newborn nursing.

The soft schluup, schluup sounds echoed lewdly through the quiet room.

Nari’s lips moved with impressive skill. It really seemed that she had practiced kissing with her mother every day.

She didn’t merely suck with her mouth. She also rubbed my lips with the soft flesh inside hers as though massaging them, and tugged lightly on my lips to create tension.

Each delicate movement awakened every nerve in my lips.

After teasing my lips sufficiently, Nari finally began moving her tongue.

The tip of her long tongue parted my firmly closed lips and cautiously slipped inside.

That was when the real kiss began.

Nari’s tongue technique, honed through daily practice rather than relying solely on her natural gift of a long tongue, was incredible.

At first, it was incredibly gentle. She softly wrapped her tongue around mine and coaxed it as though they were dancing.

Then she suddenly scraped the roof of my mouth with the tip of her tongue. My body flinched and trembled at the unexpected stimulation.

“Mmm, smooch, slurp, schlup, hwaap….”

The wet sounds of Nari kissing filled the room.

Her tongue showed no sign of stopping. She swept over every corner of my gums and persistently pushed into the insides of my molars.

It was as though she were searching for every hidden pleasure switch inside my mouth.

At first, I was helplessly swept along by her dazzling lead. But as I gradually grew accustomed to it, I wanted to take the lead myself.

So I wrapped one hand around the back of Nari’s neck and pulled her toward me.

Then I pushed 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.

“Mmph…!”

Startled, she hesitated for a moment, unsure how to move her tongue. I ignored her hesitation and explored her mouth.

Just as Nari had done—or even more intensely. I pressed down on her tongue with mine and licked the tender flesh inside her mouth.

Our kiss grew more and more intense. We forgot even to breathe as we swallowed each other’s saliva and mingled our tongues.

Our lips had already grown hot from being pressed together so long that it felt as though they would blister if we kept kissing.

While we frantically mingled our tongues, I took Nari’s hand from the bed and placed it on my thigh.

It was an obviously perverted move that made my intentions clear, but I didn’t care.

Nari immediately realized what I meant. With a smile in her eyes, she gently stroked the bulge of my cock through my pants.

With a breathy exhale, our long kiss finally ended. We faced each other and panted heavily.

Her eyes were completely unfocused with pleasure, and her lips glistened with my saliva.

“Sihyeok.”

Nari called my name, as if asking for permission.

“May I lick your body a little?”

“As much as you like.”

Once I gave her permission, Nari began licking my ears and neck as though she had been waiting for me to say it.

The sensation of her ticklish yet hot breath against me was incredible. She teased me for a long while by licking my body.

I finally brought up the main point.

“Finish what you were doing in class.”

I pointed at my cock and ordered her.

“Fellatio. Start.”
