The Glans Fellatio Master Appears
Before Chaerin put her mouth on my cock, she looked up at me with pure confidence in her eyes.
Then she took alternating mouthfuls of warm water and cold water and finally cradled my glans between her lips.
Watching her copy Seol noona’s routine so carefully was both adorable and wickedly cute.
“Temperature’s fine.”
The moment I said so, Chaerin’s tongue found my glans.
A hot, wet sensation wrapped around the head. She was approaching this with a technical focus that felt different from every sexual processing session so far.
Just as the theory lecture had taught her, Chaerin spread her tongue wide and pressed it softly across the surface of my glans, licking in smooth strokes. Soft flesh gliding and enveloping the head—that was the feeling. Conscious of technique, her tonguework was a little clumsier than noona’s, but even that clumsiness was stimulating.
“Chooop, churrrp, chuuut…”
From the first technique to the last, Chaerin worked through everything she had learned. Her flattened tongue pressed gently against my glans, and the way she licked the ridge stayed reasonably steady. For a beginner, her overall skill was solid—perfectly serviceable.
But after tasting Seol noona’s near-divine technique just moments earlier, a few shortcomings stood out.
“Sihyuk, if you don’t mind, could you give a short bit of feedback to everyone once they finish their practice?”
When Chaerin’s turn ended, Seol noona asked the favor, so I delivered my notes.
“Chaerin.”
“How was I?”
Having finished every technique, Chaerin wiped a sheen of sweat from her brow. Kneeling and working the fellatio slowly had clearly worn her out. How hard she had tried was obvious at a glance.
She looked up at me with eyes full of expectation. I did well, right? was written all over her face. That only made me more careful with the feedback.
“Overall it was excellent, but I wish the temperature inside your mouth had been a little warmer. Right now it feels slightly lukewarm. And that last stimulation of the urethral opening put too much force into it. It felt more like stabbing than tickling.”
At my critique, Chaerin’s confident expression crumpled in an instant. She stuck out her lower lip, pulled it back in, and muttered under her breath.
“…Got it.”
Frustration was plain on her face, but she obediently returned to her place and stood. The look in her eyes said she was determined to give a perfect blowjob next time no matter what.
“Still, you did really well. I’m looking forward to next time.”
That final addition smoothed her expression out again.
Next was the vice president, Cha Ayeong.
Long black hair, a cold cat-eyed beauty. Even when she knelt in front of me, that icy expression never thawed. Without showing a flicker of emotion, she finished the textbook jaw stretches and mouth-temperature control.
Ayeong’s tongue met my glans. The temperature was nearly perfect—warm without being scorching, exactly the ideal Seol noona had described. The soft texture created by just the right amount of saliva was first-rate.
But it was too soft. She licked as carefully as if she were handling fine porcelain, so the pleasure only skimmed the surface. On top of that, there was no wet sucking sound and no change in her face, which left the mental satisfaction wanting.
“Vice President.”
When I spoke mid-session, Ayeong stopped her tongue, blinked, and looked up at me.
“Put a little more strength into it. Not enough pressure.”
She immediately tightened her mouth. The moment her lips clamped down and her tongue pressed firmly into the glans, the intensity of the pleasure shot straight up. It felt so good I leaned back in the chair and let out a sigh like a man sinking into a hot bath.
After Ayeong finished practicing all five techniques, I gave her feedback too.
“You were short on force at first, but you’re excellent at taking feedback. Once you get a little more used to a cock, you’ll be even better.”
Even at the praise she showed no real change of expression, only tipped her head in a small nod before returning to her place. For a moment I found myself wishing I could see that blank face twist with pleasure the way it had during the physical exam.
Then came Subin’s turn. She stood in front of me wound tight with nerves.
“Um… Sihyuk. It’s just… my mouth is small, so…”
“It’s fine. Relax.”
Encouraged by my words, Subin opened her small mouth and began the jaw stretches. But not long after she took the glans in, her expression soured. Her jaw seemed unusually weak compared to the other girls. Yesterday she hadn’t been able to keep up the cleaning fellatio for long either—so that had been a jaw problem after all.
“Han Subin.”
Unable to watch any longer, Seol noona stepped in.
“You’re putting far too much tension into your jaw. Forcing it can injure the joint. Make sure you stretch your jaw joint every day without fail.”
“Yes, teacher…”
The way Subin looked up at me, completely deflated, was so much like a rain-soaked puppy that a laugh slipped out before I could stop it.
“Don’t push yourself. Just trying this hard is already amazing.”
At my words, Subin’s face lit up. From around the classroom I heard little sounds of envy aimed at her for the encouragement.
Subin finished her service clumsily but with everything she had. Even while she kept massaging her jaw with one hand, the look she fixed on me burned hotter than anyone else’s.
Next was the cheerful track-and-field girl, Seo Yeji. Yeji’s caress was a little rough around the edges. Rather than executing each technique with precision, it felt like she was simply working her tongue as hard as she could. But inside that clumsiness I could feel, thick and clear, how sincerely she was trying for my sake.
Unlike her usual lively self, the way she looked up at me with shy eyes while concentrating so hard—that gap in expression was pretty entertaining.
“A little rough, but I could really feel the sincerity. And that expression of yours is fun—totally different from usual.”
“Thanks for the feedback! Next time I’ll serve you even harder!”
Yeji laughed brightly at my notes and bounced back to her place.
Then it was Lee Yuna’s turn. The flashy yellow-dyed gyaru-style girl who had stood out so much during the physical exam. Just like last time, Yuna knelt in front of me with a confident smile and not a shred of nerves.
“Looking forward to it, Class President~”
She let out that pleasant nasal lilt, shot me a wink, and took my cock into her mouth in one go.
The way she only half-bothered with mouth temperature had made me write her off a little, honestly. I even thought she might be worse than Subin.
Then she blew my expectations clean out of the water.
“…Oh?”
“Uum, huu, churrruup.”
A sensation completely different from anything so far. It wasn’t that she sucked well—her tongue itself was different. Yuna’s tongue was impossibly soft and yielding, like jelly or pudding. The temperature was pleasantly warm, too.
Every time that tongue slid across my glans, pleasure washed through me as if every nerve in my body were melting. And she didn’t stop there. Yuna took two of the techniques we had learned today and remixed them in her own style.
For the first technique, the Plain, while the other girls had modulated pressure, she crushed my glans under her tongue. But because the tongue was so soft, the pleasure was enormous. And for the last technique, the Tickle, she teased the urethral opening so aggressively that it should have hurt—yet it didn’t sting at all.
Thanks to that, the urge to come rose quite a bit. A little longer and I might have finished. The other techniques were ordinary, but in my mind Yuna was already in first place.
As if she could read my thoughts, the eyes she turned up at me brimmed with confidence. She knew exactly what her weapon was.
When the fellatio ended, after she had licked the tip of the glans with the end of her tongue right to the last second, I gave her the praise she had earned.
“Your tongue… is ridiculously soft. I’ve never felt anything like that. If you just raise the finish on the techniques, you’ll be perfect.”
I was in such a good mood I didn’t hold the compliments back.
Lee Yuna wore a victor’s smile at the feedback, while over on one side of the classroom Chaerin bit her lip with a look of pure disbelief.
Then it was Lee Nari’s turn.
An ordinarily pretty long-haired beauty. But I clearly remembered the special note from her physical exam. A tongue long enough to reach her chin. During the cherry-stem-tying drill earlier, Nari had succeeded in just five seconds and stunned everyone.
With a slight lift at the corner of her mouth, Nari quietly knelt in front of me and carefully took my cock into her mouth.
“…Whoa.”
This was another kind of pleasure entirely. If Lee Yuna’s tongue had been the extreme of texture, Lee Nari’s was the extreme of surface area.
The moment the glans entered her mouth, that long, soft tongue wrapped the entire head without a single gap.
The uncanny sensation of a tongue that could circle the glans and still have length to spare. It was pure tongue-fellatio. It felt as if a small, pliant snake were coiling around the head.
When she saw how satisfied I was, Nari answered with a charming eye-smile and kept going. She demonstrated all five techniques cleanly. But she didn’t stop there.
“Teacher, may I show one technique of my own?”
Seol noona nodded with clear interest, and Lee Nari took my cock deep again.
And then… a technique I was tasting for the first time began.
Nari kept the entire glans wrapped in her long tongue and slowly started regulating the moisture inside her mouth. What had first been a slick, hot tongue surface gradually dried out, shifting into a slightly rough texture. Waves of dazzling stimulation—wet and dry, soft and coarse—crashed over the glans without pause.
“Kh…!”
The urge to come that I had somehow held back until now hit its limit. The instant I gripped the chair, Nari’s fellatio evolved another step.
“Chuk, chuk, churrr, churrr, churrr…!”
Her tongue, now dry, moved at a terrifying speed, scrubbing across the hypersensitive glans. In particular she raked the urethral opening at the tip with that faintly coarse surface.
Every scrap of focus in my body funneled into the glans, and a thrilling jolt of pleasure raced down my spine. The stimulation that had been building since morning, the reverence of twenty girls, and this absurd streak of continuous glans fellatio—everything stacked and stacked until it finally broke through the limit.
“I’m coming…!”
I cried out shortly and, at last, came inside Nari’s mouth.
Byurrrrrrt!
Hot semen poured into her mouth. Every girl in the classroom held her breath and watched. Their eyes were full of shock and unbearable envy.
Nari swallowed every last drop of my come, then looked up at me with a satisfied smile.
“How was it?”
Completely surrendered to the chair, I didn’t even register that she had used formal speech; I only nodded in acknowledgment. The victory was hers.
