My body was burning hot after going all the way to the brink of having sex with Hayeon. Even after I entered the building, the heat still lingered in my body.
The feel of Hayeon’s breasts and pussy, which I had touched just moments ago, remained vivid on my fingertips.
But my lust wasn’t something that could be relieved by that alone.
I should have ejaculated at least once.
So I planned to get a good release from the school nurse.
I wondered whether to get a titjob from the school nurse’s ample breasts or have sex with her.
Just as I was walking along, I spotted a familiar silhouette at the end of the hallway.
A flawless gait. A woman whose tightly fitted suit revealed her enticing figure in full. It was my homeroom teacher, Iseol noona.
She seemed to be heading toward the teachers’ office, several folders tucked under her arm.
Click, click. The neat sound of her heels echoing through the hallway strangely stimulated my lower body.
On the surface, noona was an educator, but I already knew how lewdly she moaned during sex.
So my plan to visit the school nurse was revised in an instant. I would have to put that off until next time.
I immediately walked toward Iseol noona.
“Teacher!”
Still aware that I was inside the academy, I called out to noona as politely as possible. She looked at me and smiled warmly.
“Oh my, Sihyeok. What a coincidence. Were you out taking a walk?”
Her voice sounded even softer and kinder in the hallway. But my mind had no room for such innocent thoughts right now.
My body, heated to its limit by my encounter with Hayeon, wanted relief immediately. And I wanted that relief from a pussy, specifically.
I took another step closer and whispered so quietly that no one else could hear.
“Teacher, please give me some sexual relief.”
Iseol noona’s eyes widened for a moment at my blunt request. Then a small smile gradually appeared around her lips.
A woman would naturally feel pleased when a man asked her for sexual relief. That was common sense in this world.
“Now?”
“Yes. Right now.”
My firm tone brought a faint blush to noona’s cheeks.
“Understood. Follow me.”
Noona walked confidently toward the sexual-relief room.
Her gait was elegant as usual, but somehow the movement of her hips seemed a little more pronounced.
Was she unconsciously swaying her hips in anticipation of the service to come? Or was she deliberately trying to seduce me?

Whatever the answer, I’d soon be squeezing that plump ass of hers.
We walked down the hallway without a word and stopped in front of the men’s sexual-relief room.
When noona opened the door, a spacious room appeared, complete with a comfortable sofa, a large bed, and a shower room.
Before noona could say anything, I undid my pants buckle without hesitation.
Iseol noona’s shoulders flinched at the sound. I lowered my pants and underwear, freeing my cock, already burning with arousal.
The cock I hadn’t managed to empty with Hayeon emerged again. Some pre-cum had gotten on it from touching that woman’s pussy earlier.
“Teacher.”
I sat on the bed and called out to her, still standing by the door.
“Could you show me what we learned today one more time?”
A playful smile appeared on Iseol noona’s face as she immediately understood what I meant.
“Hehe, I can’t refuse my student’s request for a review.”
Noona knelt at my feet without the slightest hesitation. Her suit skirt pulled taut, revealing the full, provocative curve of her ample buttocks.
Then she placed her palms on the floor and assumed a dogeza position, pressing her forehead to the ground. It was a posture of perfect submission.
“I’m Yoon Iseol, your homeroom teacher, and I’ll handle your sexual relief today.”
It was my favorite dogeza of all the submissive poses I had seen today. I nodded with a satisfied smile.
Noona carefully raised her head. She gazed up at my cock with eyes filled with awe and lust, then slowly brought her lips to it.
-Smack.
Her soft lips lightly touched the tip of my glans, then pulled away. Of course, that couldn’t possibly be the end.
Noona’s lips moved with precision, beginning a pilgrimage across the various parts of my cock.
The shaft, the sides with their prominent veins, and even my balls. Smack, smack, smack. The sight of her kissing it reverently yet utterly lewdly made my cock swell as hard as it could.
“I’ll teach you how to caress the shaft during our next session.”
She grinned and opened her mouth.
“Instead, today I’ll give you a handjob—something you haven’t learned yet.”
Noona’s low whisper was no longer the voice of a gentle teacher.
Her voice now overflowed with sultry confidence. She held up the thermos beside her.
“Novices need hot and cold water to control the temperature, one of the basics of fellatio, but a master needs only hot water.”
Noona took a sip of the hot water from the thermos and swallowed it. Then she brought her lips to my cock again.
“Oh…!”
As expected, this was an entirely different beginning from the blowjobs given by ordinary female university students.
A cozy, slightly warm softness enveloped my entire glans. It was a strangely pleasant comfort, as though I had dipped my glans into pleasantly hot water.
My body relaxed on its own, as if I were receiving a massage.
Each time noona’s tongue lightly licked my glans, just the right warmth spread along my nerves and throughout my body.
Noona’s tongue suddenly spread wide and covered my glans. As it slowly rotated over me, her hand had already grasped my shaft and was moving up and down at a steady pace.
-Slurp, slurp.
The soft movement of her tongue and the smooth friction of her palm harmonized without me even realizing it.
When our eyes met, noona suddenly changed the movement of her tongue. Its tip slowly crawled along the sensitive boundary just beneath my glans.
Her tongue gently licked the boundary between the glans and shaft. While it did so, her hand stopped moving and gripped the base of my cock.
A jolting pleasure pierced me from top to bottom. She was tickling me with her tongue while gripping the base with her hand… This was incredible.
Perhaps remembering that I preferred it counterclockwise, noona continued licking the boundary in a counterclockwise direction.
Before long, the third technique came into play.
Noona lightly gripped my cock with her hand, then rubbed my glans against the roof of her mouth instead of using her tongue.
It was a firm yet smooth sensation, completely unlike her tongue.
An unbearable pleasure, as though she were gently scraping my sensitive parts, surged upward from the base of my cock.
At the same time, noona’s fingers began softly rolling my balls.
Rough above, gentle below. I couldn’t think straight.
Noona’s control over the rhythm and intensity was incredible. As I marveled at it, her mouth changed again.
The mouth that had been wet and slick moments before began to dry out after noona inhaled several times.
The slick sensation became dry and rough, and the friction rose sharply. I had been mistaken to think my glans had grown numb after being erect for so long.
Her suddenly dry mouth was stimulating enough to jolt me fully awake.
The same was true of noona’s hand. Its gentle strokes had transformed into a vigorous handjob, gripping and shaking me forcefully.
And then came the final technique. The tip of noona’s tongue sharpened, and she began directly attacking my urethral opening.
-Tap, tap, tap-tap-tap.
Short, fast, merciless stimulation. This was cheating.
An intense pleasure surged from somewhere deep below, as though I had been electrocuted.
Noona gripped the top of my cock with her left hand and the underside with her right, shaking it even more forcefully.
The frightening part was that whenever I managed not to come, she started these techniques over from the beginning.
Sometimes she changed the order; other times, she intensified them to make the stimulation even stronger.
Noona’s blowjob was so skillful that I could no longer hold out.
I managed to endure through the second cycle, but anything beyond that was impossible.
“Huff, huff… I think I’m going to come.”
At my words, noona redoubled her efforts as though she had been waiting to hear them. Her suction was powerful enough to hollow out her cheeks.
At the same time as I felt my glans being sucked inward, something hot surged up from deep within my balls.
My thighs tensed hard, and I ejaculated on the spot.
-Brrrshhh! Brrrsh! Brrrshhh!
A tremendous amount of milky semen poured into noona’s throat.
Even while I ejaculated, noona accepted everything without so much as a twitch. Instead, she continued the handjob and gently massaged my balls as well.
After squeezing out every last drop, she pulled my cock free, then swallowed everything with an audible gulp. It was a perfectly clean finish.
Noona looked up at me seductively, then took my cock, still twitching from the aftershocks of ejaculation, back into her mouth.
“I’ll clean it for you.”
Noona licked away every trace of sticky saliva and semen, from the shaft of my cock all the way to my balls.
I had no idea how she had done it, but there was hardly any saliva left on my cock.
She smiled in satisfaction as she looked at my cock, now even cleaner than it had been when it was covered in pre-cum.
“Even the cleanup is perfect.”
