The Coeds' Glans Fellatio Practical
The air inside the classroom had grown thick and heated from the morning's long stretch of theory and practice.
"Up to this point, we've built the foundational stamina and techniques for fellatio. From here on, we're going to combine those skills and learn how to properly pleasure a man's most sensitive, critical area—the glans."
It was fourth period, the final morning class before lunch.
"A single careless mistake from any of you can turn pleasure into pain for a man. So from this moment, hang on every word I say. Don't miss a single syllable."
She alternated between the textbook and the video, hammering home the three absolute principles that had to be obeyed.
"First: hygiene. Before you serve, your mouth must be perfectly clean. Second: pressure control. Never apply too much force. And last—the most important of all—your teeth. Never, ever let them touch."
Most of the coeds scribbled down every word with solemn faces.
Then noona began explaining the five core techniques.
"The first technique is called the Plains. You flatten your entire tongue wide and lick the whole surface of the glans with gentle, even pressure. Softness and pressure at the same time—it's an advanced move."
She played the demonstration clip of a woman performing glans fellatio with her tongue fully spread.
"Second is the Borderline. You slowly trace the ridge where the glans meets the shaft with your tongue, maintaining a steady speed for one full circle. Keeping the exact path is the key."
"Third is Palate Friction. You pin the glans against the hard roof of your mouth and gently rub it there."
"Fourth is the Texture Variation we learned earlier. Start with plenty of saliva so it's wet and slick. Once the man has gotten used to the pleasure, dry out your mouth to increase the friction."
"And the fifth and final technique: the Tickle. Point your tongue tip and lightly, rapidly flutter it around the urethral opening."
"You won't use that last one very often in everyday service. The chance of making him cum is simply too high."
"As you all know, once a man has ejaculated, it's hard for him to get hard again or cum a second time right away. We can't go around wasting his precious stamina, can we?"
When the theory ended, Iseol noona looked straight at me.
"Shall we begin the practical now?"
The classroom immediately bustled with preparations for the hands-on session.
Desks and chairs were shoved against the walls in an instant, and I took my seat once more on the chair at the center of the platform.
"I'll demonstrate first again this time."
Iseol noona started by stretching her jaw—opening her mouth wide and rolling it left and right to loosen the joint.
"Especially when you're serving someone as well-endowed as Sihyuk, this kind of thorough stretching is essential. If your jaw gets strained, you can't focus on the service."
After finishing the stretch, she took warm water into her mouth, then cold, swishing and spitting in turn to fine-tune the temperature inside. The professionalism of it already had me looking forward to what came next.
Then she knelt in front of me and gazed reverently at my fully erect cock.
She first took my glans lightly into her mouth and looked up at me, asking with her eyes if the temperature was all right.
Holy fuck…
It was perfect. Not too hot, not too cold—just the right, blissful warmth.
The carefully heated interior of her mouth, the soft flesh of her tongue and palate wrapping around the head—goosebumps raced down my spine the moment they closed over me.
It reminded me of the languid pleasure of having my hair washed at a salon years ago. But this was my cock, not my scalp, and the intensity was in a completely different league.
When I nodded in satisfaction, she began the first technique in earnest.
First technique: the Plains.
Noona's tongue flattened broad and soft, licking thoroughly over the entire surface of my glans.
"Mmmph, uum, churp…"
The instant her tongue swept across the head, pleasure flooded in. Yet it wasn't sharp.
If the stimulation had been even a fraction stronger it would have hurt, but her exquisite control of force left nothing but pure pleasure.
That deep, thorough stimulation rattled my brain. If she kept this up I felt like I could cum any second.
"Ohh…"
I had meant to keep the admiration inside my head, but it slipped out of my mouth anyway.
After finishing the first demonstration, noona pulled off and addressed the girls.
"That is the Plains technique. The key is gentle pressure with the entire tongue."
"Look at Model Sihyuk's reaction. His brows are slightly furrowed, yet his lips are parted comfortably. That's a sign of satisfaction."
She continued the demonstration like a commentator, explaining her technique and my responses in real time.
Next came the second technique: the Borderline.
Noona's tongue began slowly circling the ridge where the glans met the shaft.
At first she traced clockwise at a constant speed and pressure. It felt as if her tongue never once strayed from the exact line.
Just as I was getting used to the sensation of the ridge being licked, she reversed direction and circled counterclockwise.
The unexpected change of direction sent a novel wave of pleasure sweeping across the head.
My eyebrows twitched on reflex; she gave me a smiling look with her eyes, then stopped the blowjob to explain again to everyone.
"Most men prefer clockwise, but individual tastes vary. Sihyuk, which direction felt better?"
"…Counterclockwise was better."
"I see. In real service, all of you must watch the man's reactions and discover which direction he prefers."
The third technique—Palate Friction—was even more intense.
Noona first laid her tongue flat beneath my glans. Then she tensed the muscle and lifted the head upward as if cradling it.
I felt the strange sensation of the upper surface of the glans being pressed firmly against the hard roof of her mouth.
Holding that position, she moved her tongue in tiny forward-and-back motions, rubbing the glans meticulously against the rough texture of her palate.
This was stimulation of an entirely different kind.
A moment later she lowered her tongue, took my cock in one hand, lifted it, and began rubbing the glans directly against her own palate.
The firm yet smooth texture—different from the tongue—seemed to awaken every nerve ending on the surface of the head.
"You can lift the cock with your tongue and grind it against the palate, or you can use your hand to assist like this."
Having the angle controlled by her hand made the friction feel far deeper and more powerful.
The fourth technique, Texture Variation, was pure artistry.
At first her mouth was flooded with saliva, wet and slippery as it toyed with the glans. Then it gradually dried out.
As the friction rose, the stimulation grew sharper by degrees.
If it had been dry from the start it would have hurt, but my glans had already been hard for a while and had dulled a little; now the sensation was exactly right.
I could feel the head becoming hypersensitive all over again.
Receiving glans fellatio with the fourth technique, I finally understood why this practical had a set order.
If she had scraped my glans with a dry, rough tongue right from the beginning with no warning, it would have been closer to pain than pleasure.
But the three preceding techniques had served as perfect foreplay, thoroughly warming up my cock, so the sharp stimulation of the fourth technique arrived as pure pleasure, never pain.
Starting soft and steadily building the intensity—that was the moment I learned the importance of sequence with my own body.
The fifth and final technique, the Tickle, was the crowning flourish.
Noona's pointed tongue tip fluttered lightly and rapidly around the very tip of the glans—around the urethral opening.
A dizzying sensation that felt like I was about to cum shot straight through my hips.
I wanted to beg her to keep blowing me just like that.
Unfortunately, noona had only been giving a demonstration for the class and stopped there.
"That concludes it. As you saw, if you execute these five techniques in order, a man can feel pleasure without any pain."
The moment her demonstration ended, I couldn't help being impressed.
The blowjobs Chaerin had given me until now had been good in their own way, but this was on another level entirely.
The skill of an Academy University graduate—and a teacher at that—surpassed anything I had imagined.
At the same time I found myself looking forward to how much better Chaerin's blowjobs would become after learning these techniques. I was going to have to start asking for morning fellatio every single day.
"All right, come up one by one and practice."
The classroom seethed with excited heat.
The coeds waited for their turns, lips already moving as they silently rehearsed the demonstration they had just watched, faces flushed.
Just the thought of taking a man's glans into their mouths was enough to make them happy.
At Iseol noona's words, Chaerin stepped forward first.
Without the slightest hesitation she knelt in front of me and began a fairly practiced jaw stretch.
The way she worked the joint left and right even carried a grim determination.
It was a secret from Chaerin, but the thought of that serious face sucking on my glans only made me harder.
