I approached Iseol-noona. Every woman in the classroom fixed her attention on me.
"Teacher."
"Yes, Class President."
"Would you put your hands on the blackboard and stick your ass out for me?"
At my words the air inside the classroom froze for an instant.
What broke that silence was not shock or condemnation but soft gasps laced with wonder and excitement.
Without a second's hesitation Iseol-noona turned, as obedient as a well-trained bitch in heat. She planted both palms flat against the blackboard, bent at the waist, and thrust her round, plump ass straight back toward me.
The Kegel devices were already buried in her pussy and ass, so her lower half was completely bare.
Twenty pairs of eyes belonging to my female classmates locked onto a single spot: Homeroom Teacher Iseol-noona's ass and the two holes nestled between those cheeks.
Savoring every stare, I stepped up behind her. Then I began to draw the devices out one by one, slow and deliberate. Each time one slipped free, noona's pussy and ass clenched and twitched.
I set the wet toys on the teacher's desk and reached for the pussy already dripping with fresh juices.
"I should loosen you up a little more before I put them back in."
My fingers sank into her. The slick entrance welcomed them as if it had been waiting.
"Haa... ah..!"
The filthy thrill of fingering my teacher right in front of the entire class made me bolder. I pushed deeper and stirred her walls.
-Squish, squish.
The wet sounds rang through the quiet room. Iseol-noona could no longer form words. She only tipped her head back, biting her lip hard to smother the moans that kept trying to escape. Even so, she clearly hated the idea of her students watching her come undone.
Her body trembled in fine, continuous shivers; her pussy poured hot slick in time with every motion of my fingers.
"As expected of an Academy graduate your grip is on another level, Teacher."
At first I hadn't noticed. But after handling more than twenty pussies just minutes earlier, the subtle differences stood out. Iseol-noona's walls were springier than any of the students', clamping greedily around each tiny movement of my fingers.
"I... hngh... do Kegels and... other exercises... every day...."
She answered between ragged breaths. I glanced back over my shoulder at the class.
"You all heard that? Work hard at your Kegels and you can become a premium hole that makes a man happy-just like Teacher."
Twenty pairs of eyes sparkled with pure admiration.
I returned my attention to her pussy, not merely curling my fingers but pulling them free and driving them back in, stretching and churning her deeper, wider.
-Squelch-squelch-squelch.
The lewd, sticky sounds grew louder. So much juice was pouring out that just listening to it made my cock throb.
Iseol-noona held on for more than a full minute before her limit finally shattered.
"I-I'm cumming... Class President... hngh...!"
Her back arched hard; her ass shook violently. At the same moment a hot fountain of juice erupted, spraying across the platform floor with a sharp hiss. She rose onto her tiptoes and convulsed through the aftershocks,
Once I was sure she had climaxed, I gave her dripping pussy a few sharp, open-handed smacks. My palm caught her clit and she hiccupped, thighs snapping shut.
Wearing a satisfied smile, I coated the devices thickly in her fresh juices and slid them back into her still-twitching pussy and ass in turn.
When it was finished she sagged against the desk, gulping air as though completely spent.
"...Thank you."
She offered polite gratitude to the man who had just fingered her to orgasm. If we had been alone she would have dropped the formal speech. I found myself a little disappointed.
After catching her breath, Iseol-noona dragged the remaining chair to the center of the platform and sat. It was no ordinary seat. She spread her thighs wide so that both her pussy and ass were fully on display for the entire class.
"Now watch carefully. When you do Kegels, this is exactly where you need to squeeze."
I was momentarily speechless. The same teacher who had just climaxed on my fingers was casually exposing her genitals and continuing the lesson as if nothing had happened. The women accepted the sight as completely natural, listening with earnest, focused faces.
Once again the world left me reeling.
Following her demonstration, every woman in the room began contracting her own pussy and ass. Feedback chimes of every tone rang from the smartphones linked to the smart Kegel devices. Noona moved from student to student, correcting posture, leading the class with real passion.
Standing idle felt boring, so I sat down and joined the exercises myself. No harm in it for a man, after all.
"There will be a test on these Kegels later, so practice hard."
-x-X-x-
The chaotic morning finally ended when the lunch bell rang. The long, intensely arousing sex-ed block was over.
The cafeteria building stood a short walk from the main hall where sex-ed was held. Even on the way, dozens of women drifted around me at a careful distance that never quite interfered. I didn't mind the attention. Being wanted by women felt good, no matter the reason.
Inside, the dining hall was enormous. Hundreds of female students chattered over their meals; among them I spotted a handful of other men-four, maybe. Since waking up in this body it was the first time I had seen so many at once; the novelty was strange.
They ranged from ordinary to mildly handsome. Around each of them, female students clustered like worker bees around a queen. I was no different. Chaerin and Subin had already claimed the seats on either side of me; Yeji sat directly across. The rest of our table filled with classmates.
Food service at the Academy was sharply divided by sex. While the women queued in long lines, the men simply remained seated. Moments later staff approached our tables with deferential bows and laid out a full banquet.
In front of me appeared a sizzling iron-plate steak, grilled freshwater eel lacquered in sweet-savory glaze, and a rich abalone-gut porridge. Alongside them came steaming oysters fresh from Tongyeong, asparagus wrapped in bacon, fragrant garlic-butter roast, and a deep-red glass of bokbunja juice-dishes clearly chosen to stoke a man's vitality.
The woman who had recited every item like a high-end restaurant sommelier bowed low.
"If there is anything else you desire, please say the word. We will prepare it at once."
Her words drove home again how thoroughly this world was built for men.
The moment the feast was set down, every female gaze at the table swung toward me.
"Wow... the men's menu is straight-up an emperor's banquet."
Yeji's voice held pure admiration, not a trace of envy.
I shrugged.
"First time seeing it myself. Pretty wild."
"Oh right-thanks so much for putting the devices in earlier."
Yeji's bright smile was easy to look at.
"Glad I could help."
"Help? Class President, you made the whole morning amazing."
She gave a short, glowing rundown of how good she had felt. The other women immediately piled on.
"Exactly! Not just Yeji-all of us."
It was the intellectual-looking girl with glasses, the same one who had begged me to push deeper earlier. Her name escaped me.
"Class President's hands are seriously unfair. How do you know every spot that makes a girl melt?"
The question from the girl two seats over left me momentarily blank. I had just been poking around.
"I... just kind of figured it out as I went."
My clumsy answer set them all laughing, the sound warm with affection.
"Men really are different. You make us feel way better than we can do ourselves. Guys just know, huh?"
"That's why we have to submit to them."
Their talk flowed naturally into praise for me and worship of men in general.
"But Sihyuk, when you fingered Teacher earlier... that was so hot."
The short, cute girl flushed as she spoke.
"Right? Completely shameless. I'll never forget it as long as I live-Teacher actually cumming right in front of us..."
"Honestly it turned me on watching her lose it."
"You think you're the only one?"
They whispered among themselves, excitement barely contained. I remained the fixed center of every sentence; they elevated me simply because I was male.
Chaerin, who had been eating quietly at my side, cut in.
"Hey, can we not talk about that while people are eating? Sihyuk needs to finish his food."
"Ah-sorry, Class President."
"We got carried away."
Thanks to Chaerin's intervention I managed to eat everything while it was still hot.
Once I was full, the whole table waited for me. I was about to head back to class when curiosity prompted one last question.
"What majors did you all pick?"
Answers tumbled out at once.
"Male psychology. I want to be the wife who understands her husband's heart better than anyone."
"Practical pleasure techniques! My goal is top practical scores so I can be a pleasure-type wife."
"Economics. So I can earn lots of money for my husband."
Each face glowed with hope. The fact that every dream ultimately ended with becoming some man's wife left a strange taste in my mouth.
Lunchtime still had a little left, so I answered every comment without irritation. The friendlier I was, the harder they tried to hide their delight. Girls from other classes watched our table with open envy at the sight of a man actually conversing with them.
We finished the meal in high spirits and returned to the classroom just as the bell ended lunch. From the afternoon onward, major classes would begin.
-x-X-x-
The lunch period ended, and the bell rang to signal the start of afternoon classes.
The female university students who had been with me rose from their seats with looks of regret.
"Ah, it's already over."
"I wanted to talk more with the class president."
"I know. It would have been nice if we could take the afternoon classes together too."
They each voiced their disappointment and scattered toward their major lecture halls. Chaerin and Subin, who were always at my side, left for their own major classes as well. Just like that, I was left alone in the empty classroom.
At the academy, men were required either to ride the male-student shuttle once classes ended or to head home accompanied by at least one woman. The rule had been put in place because, despite the nation's thorough brainwashing education, far too many women still couldn't restrain their lust and would assault men.
The women's classes, however, still had a long way to go. Riding the shuttle home alone would only leave me bored out of my mind. In the end I decided to wait until Chaerin and Subin finished, and to kill time I began wandering the academy campus.
The academy was far larger and more systematically laid out than I had imagined. Leaving the classroom, I found carefully tended lawns, dense tree-lined avenues, and elegant European-style stone buildings stretching endlessly. Between the buildings, pretty gardens and benches had been placed here and there for students to rest. On the broad athletic field, the women's soccer team was sweating through a match.
Yet the scene was nothing like the soccer I knew. Their so-called uniforms were little more than bikini tops and hot pants so short that the cleft of their asses was fully visible. I had never cared much for soccer, but every single outfit was shamelessly vulgar, and the players were all pretty with outstanding figures, so I found myself unable to look away.
On the track beside them a familiar figure caught my eye. Looking closer, it was Yeji. Her attire was equally far from ordinary-a thin white sports bra soaked transparent with sweat, and blue bloomers pulled so tight that her camel toe stood out like an axe mark. Every step she took made her springy ass sway enticingly from side to side. Sweat gleamed along her back and thighs; her breasts rose and fell with each labored breath. Her ponytail fluttered in the wind, and the concentrated profile of her face was both healthy and sexy.
I involuntarily parted my lips in admiration. Yeji was only running, yet the near-bikini athlete's outfit and her voluptuous body had me rock-hard. Honestly, if she had asked me to fuck her right then, I would have done it without a second thought. I was reminded once again how weak I was to lust. Afraid the erection would never go down if I kept staring, I hurriedly averted my eyes and walked on.
Beside the track stood a massive indoor gymnasium and a swimming pool under a glass dome. The sight of the women's swim team through the glass was something else entirely. I doubted whether what they wore could even be called swimsuits. The ones in bikini-level suits were the modest ones. Some wore nothing but nipple patches that barely covered their areolas and a single hand-span of fabric that clearly outlined every strand of pubic hair-another shock. One nameless student in particular had such large breasts that they bounced heavily every time she broke the surface. The design cared nothing for reducing water resistance; its sole purpose was to draw a man's gaze.
Marveling at the women's lewd clothing and the sprawling campus, I kept walking. Only after a long circuit did I finish a full lap. The place truly deserved the name "university." My feet eventually stopped in front of a familiar building-the one that housed the infirmary and the Male Sexual Processing Room.
The memory of taking my homeroom teacher, big sister Iseol's virginity in that very processing room yesterday made my cock twitch hungrily. I stepped into the infirmary. I had no real business there; I was simply bored and thought I might scrounge a snack from the pretty school nurse if luck was with me.
Inside, the place was dead silent. A few papers lay on the desk and no one was in sight. More precisely, one of the soundproof booths at the back-rooms provided for female students to masturbate and stave off estrus sickness-had its door firmly shut. There was no lock, only opaque glass that let you see a silhouette of whoever was inside.
Focusing on the glass, I made out a blurry figure writhing on the bed.
Who is it?
Curiosity pulled me closer to the soundproof booth.
"Hnn... haa..."
Faint female moans and the wet sound of something slick rubbing together leaked out. The realization that a woman was masturbating right on the other side of the door set my heart pounding. The urge to open the door and walk in flashed through my head. Of course I shouldn't...
No. Thinking about it, why can't I just go in?
In my previous life it would have been unthinkable. Barging into a room where a woman was masturbating would have branded me a sex criminal and ruined me forever. But this world was different. Men were beings to be protected. Women existed to satisfy men's desires. The passionate lecture big sister Iseol had given that morning echoed vividly in my mind: men were the hope of humanity's survival, so even their trivial desires deserved respect; for a woman to show her body to a man was not shame but glory. Therefore, unless a man committed a truly serious crime, he was simply let off. Walking into a room where a woman was masturbating? That wasn't a crime at all. If anything, the woman caught in the act should be grateful.
The laws and common sense of this world mocked the moral shackles inside me and pried them open. For a moment the unease that had risen with the memo I found yesterday tried to surface again. I had sworn to hold back from lewd things and be careful with my body. That cool-headed resolve proved utterly powerless against the lust boiling up and the curiosity about the masturbation happening beyond the thin door. The front of my pants was already swollen to the point of pain.
I'll just take a quick look, apologize, and leave. That should be fine.
Making excuses to myself, I carefully opened the door.
What met my eyes was a sight beyond anything I had imagined.
On the bed inside the room, the school nurse lay with her white coat thrown open, legs spread wide, masturbating with fierce intensity.
"Hnn, hnn...! Ah, unngh...!"
Eyes closed, she frantically rubbed her pussy with fingers glistening from her own juices. Through the open coat her full breasts spilled free, pink nipples already hard and erect. Completely lost in her own pleasure, she had no idea I was there. Every time her fingers brushed her clit her back arched, and lewd cries spilled out with her hot breaths. Sweat-matted hair showed just how long she had been at it.
After a while she cracked her eyes open, spotted me, and startled violently.
"W-Who's there! Didn't you see someone's inside...!"
The voice was furious at first, but the instant she recognized the person in the doorway her tone shrank to almost nothing. Anger vanished, leaving only extreme fluster and shame on her face.
"S-Sihyuk? What brings you here...?"
I reflexively delivered the excuse I had prepared.
"Ah, I'm sorry. I didn't realize anyone was inside and walked in."
My eyes, however, paid no attention to her words. They were locked on the way she hastily tried to close her coat and pull on her panties-pubic hair soaked and sticky with love juices, black stockings that rose precariously high on her thighs, and soft white skin still trembling faintly from the aftershocks of pleasure. The first time I had ever watched a woman masturbate was far lewder and more stimulating than anything I had imagined. My erect cock strained hard against the front of my pants.
From the name tag I had just glimpsed I learned the school nurse's name was Lee Seoyeon. An ordinarily pretty face and a voluptuous body-l was already too excited to hold back.
"I'm really sorry you had to see me looking so unsightly...."
Seoyeon finished pulling on her panties and stood from the bed, desperate to escape the situation. But when she found me still blocking the doorway and refusing to move aside, she faltered. Her gaze drifted, almost against her will, to my cock. The massive outline stood out unmistakably fully hard.
-Gulp.
I heard her swallow dryly. She hesitated a moment longer, then gathered her courage and asked,
"Do you need sexual processing?"
Seoyeon's voice trembled faintly, yet clear anticipation ran through every word.
I couldn't refuse her offer. No-I never even considered refusing.
Walking around the academy with a cock about to explode was pure agony. And more than anything, the woman right in front of me was just too damn hot.
Still, the faint wariness left by yesterday's memo made me hesitate. So instead of answering, I simply stood planted in front of her and stayed silent.
Taking my silence for consent, Seoyeon gathered her courage once more. She gently took my wrist and drew me toward the bed with a soft, irresistible pull.
She had put her panties back on after taking them off, so the outline of her pussy showed vividly through the thin fabric.
Seoyeon sat me on the edge of the bed and dropped to her knees on the floor, assuming the position for a blowjob. The moment I saw that submissive posture, a better idea struck me.
"Hold on."
I caught her by the shoulder before she could kneel fully and spoke in a low voice.
"Finish what you were doing earlier. Show me."
"Huh...?"
"Masturbating. I want to watch."
Seoyeon's eyes went round with fluster. But only for a second; shame and a strange excitement bloomed across her face at the same time. Displaying her most private act right in front of a man-that was a rare luxury for the women of this world.
"Okay... I understand."
She nodded obediently and climbed back onto the bed.
Then she stretched her legs straight out toward me and leaned back against the headboard. Without the slightest hesitation she peeled off her panties and tossed them aside, leaving her pussy-slick and gleaming with love juices-completely exposed.
Seoyeon began gently pressing her clitoris with her own fingers, still sticky from earlier.
"Ha... euh...!"
Knowing my gaze was locked on her pussy sent her arousal climbing fast. I watched with open interest and started asking questions in a lazy, casual tone.
"How often do you masturbate?"
"Ev-every day... heuh... two or three times a day... I do."
"Where are your sweet spots? The place you're touching right now?"
"Yes... here, and... euh... my breasts... and...! Hoo... ugh...!"
She answered between gasps, never once stopping the movement of her fingers. I saved the last question for last.
"What were you imagining while you were doing it?"
The moment the words left my mouth, her fingers froze. She hesitated for a heartbeat, but her brain was already soaked in pleasure; the unfiltered answer spilled out.
"...I was imagining having sex with Sihyuk."
Before the sentence even finished I was on my feet and closing the distance.
"Really?"
"Yes, really-imagining getting fucked on Sihyuk's cock, ah, ang...!"
I flung her gown wide open and pinched her stiff left nipple between my fingers. At the same time my right hand clamped down on her pussy and shoved a finger deep into her dripping hole.
-Squelch, squelch!
"Reward for answering honestly."
"Hyaaaaang!"
Already softened by masturbation, her walls parted easily for me. I barely pumped a few times before her whole body seized and she came hard.
"Haa... haa... I-I came...!"
Watching a woman collapse from nothing more than one finger never got old. Heat flooded my skull. I kept working her pussy even more roughly while she was still riding the aftershocks. When I scraped a fingernail lightly across her areola, her body jerked again.
"Heuh... w-wait...!"
She twisted instinctively to escape; I cut her off with a firm order.
"Don't move."
Her body locked in place at once. The tearful, overstimulated look on her face was adorable. I found her G-spot and began tormenting it without mercy.
"Haak... haak...! I'm cumming againnn...!"
She gasped and pleaded for me to stop, but it was far too late. Her pussy convulsed violently and shot a fountain of hot love juice straight toward the ceiling, soaking my hand and the sheets beneath her.
I dragged her still-trembling legs up and hooked them over both my shoulders. She ended up lying flat on her back while I stripped off my pants and underwear without a second thought. The instant my thick cock sprang free, Seoyeon stared at it with eyes shining with pure hunger.
I pressed the swollen head against her entrance and rubbed it slowly back and forth. When I paused, she must have thought I was worried about contraception, because she rushed to reassure me.
"It's fine! I'll take the pill for sure! Please... please cum inside me...!"
I was never the kind of man who walked away from a creampie. This wasn't my first time either, so unlike with Iseol noona I showed no mercy from the start. I gripped her waist and buried myself to the hilt in one brutal thrust.
-Thwup!
"Ugh...! Haang, ang... this is a real cock...!"
The bedframe screeched loudly. My glans tore straight through her hymen and slammed hard against the mouth of her womb. Seoyeon screamed a raw mix of pain and pleasure, but the pain melted almost instantly, drowned under a tidal wave of overwhelming sensation.
"Ah... aaaang! Good...! So good...!"
Just being filled was enough to send her into a massive climax; her body twisted and bucked. That virgin pussy that had waited a lifetime for a man refused to stay still for even a second. Every ridge inside her clenched and rippled as if welcoming me home. She was so tight I had to put real force into pulling out.
I leaned down and whispered against her ear.
"Teacher, relax a little. I can't move if you keep squeezing like that."
"But... heuh... it's so big... I can't help... the strength..."
She answered between ragged breaths. I grinned and began rocking my hips slowly, just a centimeter in, a centimeter out. Even that tiny motion made her whole body twitch.
"Haueu...! Ah...!"
I gradually picked up the pace-still shallow, but faster and faster. The moment she started matching my rhythm I stopped dead, leaving her dazed. Once her pussy had molded itself to the shape of my cock, I started moving again in earnest.
The soft wet sounds of flesh on flesh grew quicker. Tingling pleasure raced from my glans straight up my spine. I surrendered to instinct and began slamming into her like an animal. The heavy, wet slap of our bodies colliding was filthy and delicious.
-Thwup! Thwup! Thwup!
"Wait... wait a second...! Too fast...!"
She begged, so I sealed her mouth with a rough kiss instead. My tongue invaded and she didn't even try to resist; she just melted into it. Her walls clenched hard around me as another orgasm hit. I savored every crushing pulse while keeping my hips moving.
Without anyone teaching me, my thrusts were growing more skilled by the second. Maybe I really was a natural genius at this.
Seoyeon's pussy was already trained to my rhythm; it fluttered and gushed in perfect time with every stroke. She screamed into another climax. I drove even deeper at that exact moment, burying myself to the root. The convulsing folds wrapped around me so tightly I had to pause just to breathe.
While she was still trembling in the afterglow I started moving again-this time deep and heavy, knocking against her cervix with every thrust. Each impact made her body bounce on the mattress.
"Ah! Ang! There...! Right there...!"
I had found her weakest spot. I focused on it, grinding in circles, then slamming down hard, tormenting her from every angle. She was completely at my mercy, drowning in wave after wave of pleasure. Feeling like something was still missing, I crushed my mouth to hers while my free thumb attacked her clit without mercy.
"Hegiiiiik...!"
Her eyes rolled back. Assaulted at the same time by my tongue, my thumb, and the cock buried inside her, she stretched her legs rigid and shook violently through another orgasm. White foamy juices and clear squirting fluid erupted in a fountain.
It had to be pleasure on a level her lonely masturbation sessions could never touch. But the switch inside me still hadn't flipped off. Seeing her gasping and spent only made my lust burn hotter.
I didn't give her a moment to recover. Hooking just her right leg over my shoulder, I started pounding her at a new angle. The different pressure made her cry out helplessly. I explored every inch of her body-groping, kissing, biting-learning a woman's body by feel. When I squeezed her breasts she winced, but her pleasure-soaked nerves converted even that pain into sweet stimulation.
After a long, relentless stretch of fucking I finally unloaded a thick, hot flood of semen deep inside her. Seoyeon was completely drained; she didn't even have the strength left for a cleaning blowjob. I pushed my cock-still glistening with my cum and her juices-straight against her lips anyway.
"Uup... eup... chuuut... churururup... chyuup."
She barely managed to open her mouth and take me in. There was almost no power in the blowjob, but the earnest way she tried to lick my glans clean with her tongue was adorable enough that I was satisfied.
When it was over I got dressed, but Seoyeon stayed sprawled naked across the bed. The sight made me hard again, so I slipped a couple of fingers back into her pussy and stirred. Almost nothing was left to come out; she only managed a weak spurt and a final shudder.
I stepped out of the soundproof booth. Somehow Seoyeon dragged herself upright, staggered into her clothes, and followed me. Outside the Health Office she gave me a dazed farewell.
"Goodbye...."
I smiled, told her to take care, then casually grabbed a full handful of her heavy breasts.
"Your pussy squeezed really well. Next time build up some stamina so we can go again."
"Yes...!"
At the praise her face lit up like a girl in love, cheeks burning. I left the Health Office in a thoroughly satisfied mood.
-x-X-x-
Walking the academy grounds, I realized the final period was almost over. I left the places I still hadn't seen behind and headed for the classroom.
As I moved down the empty hallway, a familiar figure appeared up ahead. It was my homeroom teacher, Seol-noona. She spotted me, hesitated for a beat, then walked straight toward me.
"Sihyuk, do you have a moment? There's something I need to talk to you about regarding the caressing practice class that starts tomorrow."
After checking that no one else was around, she lowered her voice and continued.
"Normally the students practice on silicone models. There just aren't many men, and a lot of them feel uncomfortable exposing themselves in front of women."
A faint flush colored Seol-noona's cheeks as she got to the point.
"But if you're willing, Sihyuk... would you consider being the male practice model for the class? Nothing teaches better than feeling a living man's reactions firsthand. It would be an incredibly valuable opportunity for everyone."
Worried I might refuse, she hurried to list the benefits.
"Of course I'm not asking for free. The academy knows how demanding the model role is, so they offer several forms of support."
She ticked the points off on her slender white fingers.
"First, a very generous special scholarship. We can also adjust the practice content a little to match your preferences... and you get to choose your practice partners yourself."
Her eyes locked straight onto mine.
"Any girl you like. Chaerin, Subin... even me."
Hope sparkled in her gaze. Almost whispering, Seol-noona asked the final question.
"So what do you say, Sihyuk? Would you... be willing to take on the role of practice model?"
Something detonated inside my skull.
They want me to become teaching material for caressing and sex practice classes?
Every girl in my class might end up giving me handjobs, blowjobs, maybe even fucking me?
This was an offer I couldn't refuse even if it killed me.
I cleared my throat once and answered in the calmest voice I could manage.
"If it's for everyone's benefit, I don't have much choice. I'll be the practice model."
Seol-noona's face lit up brilliantly at my answer.
-x-X-x-
When class ended I left through the school gate with Chaerin and Subin. Plenty of other students were heading home at the same reasonable hour. Once again the girls' outfits caught my eye. Back on Earth those clothes would have earned them the label of total slut without any room for argument, yet here they strolled along without a care. If the weather warmed up even a little more, I half expected to start seeing naked girls on the streets.
Near the main gate, expensive-looking foreign cars sat lined up in a row. Relaxed men lounged inside while swarms of women competed to fawn over them. It was a world completely different from mine as I walked.
We talked about how our major classes had gone that day while heading home. Along the way Subin carefully asked Chaerin and me,
"Hey... want to come over for dinner tonight?"
The invitation surprised me for a second, but I quickly guessed her reason. HSDD. The condition I'd asked her to explain during Kegel class. That was why she was inviting us.
If I wanted to get closer to the truth behind the memo, I needed as much information as possible from the people around me. I planned to ask not only about HSDD but also about that suspicious cult.
Subin's house sat right next to ours, yet the atmosphere was night and day. After passing through a neatly tended little garden and opening the front door, warm lighting and a soft floral scent welcomed us. For a home shared by just Subin and her mother it was surprisingly spacious and cozy. Expensive-looking paintings hung on the walls, and a grand piano with sheet music sat in one corner of the living room.
"Your mom isn't home from work yet?"
"Yeah, she said she'd be a little late today. Make yourselves comfortable."
Subin guided us to the plush sofa, then went to the kitchen and returned with orange juice and fancy cookies. Being in her house for the first time made me a little awkward, but Chaerin seemed completely at home; she immediately pulled a board game out from under the living-room table.
We gathered around the table and started playing. It was a simple game of rolling dice and buying land.
Chaerin was fiercely competitive-every time she threw the dice she either cheered or groaned at the top of her lungs. Subin simply watched her with a quiet smile, genuine happiness written all over her face. Only then did I realize how close the two of them actually were. They'd said they grew up in the same neighborhood; they must have been good friends for a long time.
The game went on for quite a while. When Chaerin finally lost she stood up.
"I'm gonna hit the bathroom real quick."
Once she disappeared down the hallway, only Subin and I remained in the living room. The lively atmosphere settled into a silence that wasn't uncomfortable at all. I decided this was my chance and carefully brought up the real topic.
"Can you tell me about that condition you promised to explain after school? HSDD?"
Subin's expression stiffened slightly. She fussed with the cup in her hands, hesitating. The ticking of the grandfather clock in the living room suddenly sounded deafeningly loud. At last she seemed to make up her mind and spoke in a small voice.
"That... Chaerin already knows about it too."
Her gaze stayed fixed on the floor.
"HSDD is short for Hypoactive Sexual Desire Disorder. Think of it as a hereditary disease that's been passed down through my family for generations."
She tried hard to keep her tone calm, but her voice still trembled faintly. That tremor carried loneliness and sorrow I hadn't known about.
"You already know women have crazy strong libidos. That's normal. But my family isn't like that. We don't need to masturbate every day the way other people do, and looking at a man doesn't automatically turn us on."
She paused and took a deep breath.
"So ever since I was little I've always been treated like a freak. The other girls called me a stone woman, a wooden doll... and guys never showed any interest in me at all."
Transparent sadness welled in her eyes.
"That's why I don't have any friends. Except for you and Chaerin."
Her confession made something in my chest ache. I finally understood the way the school nurse's attitude had turned ice-cold the moment she learned Subin had HSDD. The condition seemed to be treated as a defect, a disability, a social stigma. Now I understood why Subin's pussy had barely gotten wet during the physical exam unlike every other girl, and why she'd broken down crying that her own body was disgusting.
In a world where everyone saw through the single lens of sexual desire, she had been born with different eyes. HSDD was the two-eyed person persecuted in a land of one-eyed people. Minorities that the majority cannot understand are always the first to be cast out.
"Subin."
My voice came out far softer than I intended. At the sound of her name she lifted her head from the floor. And then I saw it-the deep fear that had settled into those emerald eyes. This went beyond simple surprise or embarrassment. She was terrified. Terrified that now that I knew about her HSDD I would despise her, loathe her, and ultimately push her away just like everyone else.
Looking into her eyes, I could suddenly picture the life she must have lived until now: pointed at by friends, misunderstood by teachers, ignored by adults. Yet even while trembling with the fear that I might abandon her and leave her alone again, Subin hadn't run or hidden. Instead she had gathered the courage to lay her painful, shameful wound bare in front of me.
Why? Guilt over not wanting to deceive a friend? Or the desperate hope that even someone like me might understand her? Which answer was correct didn't matter.
Something hot surged up from deep inside my chest-a tangled mix of emotion, apology, and a fierce protective instinct that wanted to shield her.
I didn't hesitate any longer. I wanted to end her fear. Rising from my seat, I sat down right beside her and carefully, gently stroked her hunched back, treating her as if she were a fragile glass ornament.
"W-why... Sihyuk? Did I do something wrong?"
"No. I just want to hear more. About HSDD."
The color drained from Subin's face at those words. Head hanging low, she whispered in a voice almost too quiet to hear.
"Why... would you..."
"If you're okay with it, I'd like you to tell me. About HSDD, and about the parts of you I still don't know."
I stayed silent and simply kept stroking her back, waiting until she felt ready to speak. A moment of quiet passed. Then, as if she had made a decision, Subin slowly opened her mouth, her voice thick with unshed tears.
"HSDD is... like a curse."
Her voice was raw with old wounds.
"People treat it the same way they treat inverted nipples-as a bad omen. A body that's female, yet missing a woman's most essential instinct... sexual desire. They call us defective goods. That's how everyone sees it."
"Without desire, you can't fit in with other girls. You can't join the conversations they have every day-about guys, about masturbation, about sex. To them I'm nothing more than a doll that can't feel anything. So... I've been alone since I was little."
Subin told me about the days right after she entered elementary school.
Back then she had exactly one friend. Trusting her, Subin confided the secret that she had HSDD.
The very next day the rumor was everywhere at school.
Han Subin? She's a stone woman.
No wonder she always seemed cold. They say she has zero interest in boys.
Poor thing. Born a girl and everything....
Behind the pity hid contempt and scorn. Her classmates began openly avoiding her, as if misfortune itself might rub off on them if they touched her.
At lunch she always ate alone. Walking down the hallway she had to listen to the whispers at her back.
Even that one friend turned her face away so she could join the other children's circle.
"That was when I realized it. In this world... someone like me doesn't deserve to be loved. I'm going to have to live my whole life without friends..."
At last a single tear slipped from Subin's eye. It fell onto the table and left a damp mark.
I couldn't find a single word to say.
Anger at the absurdity of this world boiled up inside me. The weight of the pain a little girl had been forced to carry simply because her desire was a little lower than average pressed down heavily on me.
"That's why when you became my friend, Sihyuk... I was so happy."
Subin wiped her tears and looked up at me. Her wet eyes were full of desperate longing.
"You knew I had almost no sexual desire and you still didn't look at me like I was strange. You protected me instead. If you hadn't been there back then, I probably... really would have died."
I quietly pulled Subin into my arms. Her small body felt so fragile.
"It's okay."
I patted her back as I spoke.
"You're not the strange one. This world is."
At my words Subin's shoulders began to shake even harder.
She buried her face in my chest and finally let out the sobs she had been holding back for so long.
For a while the only sound was her crying-grief and the relief of finally speaking the truth all tangled together.
"I don't think HSDD is weird at all. If anything I liked that you were different from the other girls. So you don't have to feel anxious around me."
I felt the tight tension leave Subin's body.
"Even after losing your memories... you're still my Sihyuk..."
I gently wiped her tears away with my thumb. In that moment our eyes met.
Those emerald irises, wet with tears, sparkled like jewels.
I momentarily lost my words at the sight of her beautiful face. Wet lashes, cherry-red lips slightly parted. She was cute. She was lovely.
And from deep in my chest a strange, powerful sense of intimacy welled up, as if I had known her for a very long time.
My mind had forgotten, but my body still remembered Subin.
She simply gazed up at me with those wet eyes, saying nothing.
In that gaze was gratitude and relief-and the purest, deepest affection a woman can feel for a man.
Love.
A strange, sweet atmosphere slowly wrapped itself around us.
Everything seemed to move in slow motion. Subin lifted a trembling hand and laid her small, cold palm over mine.
The instant that fragile warmth touched the back of my hand, I could no longer hold back. I brought my face close to hers.
Chup.
At first it was only a light kiss-soft and sweet.
Subin's body flinched faintly in surprise, but she didn't push me away. Instead she gently closed her eyes.
Encouraged by that, I began to explore her lips more deeply.
When our tongues met I tasted the sweetness of orange juice mixed with a scent that belonged only to her.
It was an innocent kiss.
I don't know how long it lasted. Reluctantly we parted, lips leaving each other with a soft sound.
Only then did I realize what I had done and panic set in. But in that same moment Subin grabbed the front of my shirt and pulled me back.
This time she initiated it. Her courageous kiss was far more aggressive than before.
Her tongue slipped into my mouth and wrapped around mine.
Watching Subin earnestly move her tongue without really knowing how to kiss was adorable.
When we finally broke apart again, Subin was breathing hard, as if she could no longer contain the feelings overflowing inside her. She poured out her heart.
"I only ever had you and Chaerin. Only the two of you ever treated me like a person. Thanks to that... I was able to keep living. I know you don't see me as a woman. I know you only think of me as a friend. But... but after kissing you for the first time, I don't think I can hold my feelings back anymore. Sihyuk, listen...!"
Just as Subin was about to confess, the sound of Chaerin's footsteps came from the hallway.
We both jumped as if spring-loaded and hurriedly pulled apart.
Chaerin returned from the bathroom, took one look at the two of us frozen in awkwardness and the strange atmosphere filling the living room, and furrowed her brow.
"What were you two doing? Why's the vibe so weird?"
At Chaerin's question Subin flushed bright red and stood up.
"I-I'm going to the bathroom too...!"
As Subin fled, Chaerin immediately latched onto my side and pressed me for answers.
"Something really happened, didn't it? Spit it out."
The moment Chaerin's body pressed against mine, the erection that had already been raging from the kiss with Subin grew painfully hard.
It was an honest reaction that made me feel guilty toward Subin, whom I had just been kissing so sweetly.
I hastily stood up and pretended to look around the living room, putting distance between us.
"It's nothing. I just asked her about HSDD.'
"Hmm..."
Chaerin didn't drop her suspicious gaze, but then her eyes drifted down to the front of my pants and the corner of her mouth curled up.
"You're rock-hard in someone else's house. Want me to give you some sexual processing?"
She said it in the most casual tone imaginable, as if she were asking whether she should make dinner.
My head was still foggy from the sudden kiss with Subin; I didn't even have time to process the meaning of her words before I reflexively nodded.
"Yeah."
Oh no.
The second the word left my mouth I realized what a mistake I had made. But it was already too late.
The instant my answer finished, Chaerin casually pulled her top up a little and dropped to her knees right in front of me.
With practiced hands she undid the buckle of my pants and pulled down the zipper.
The way she yanked my underwear down in one smooth motion was so natural and swift it looked like she had been practicing in secret.
"Wait, Chaerin! This is the living room!"
I tried to stop her in a panic, but my words had no effect whatsoever.
In an instant my cock sprang free, already fully erect, and Chaerin seized it.
Chuuup!
"...!"
The wet heat of a woman's mouth swallowed my entire length in one go.
Just moments ago Subin's mouth had been sucking on my tongue; now Chaerin was sucking my cock.
My mind spun.
This wasn't our house. It was someone else's house-the living room of the friend who had just shared her first kiss with me in a tender atmosphere, Subin's living room.
And Subin, who had gone to the bathroom, could come back at any second.
In that extreme tension my twin little sister was greedily sucking me off.
"Hnnph, churp...! Silrp...!"
Chaerin's technique had improved to a shocking degree.
There was no trace left of the clumsy tongue movements from before.
She wrapped her soft lips around the shaft and used her hot tongue to obsessively lick up the head.
With just a blowjob she made my lower abdomen tingle.
I should tell her to stop...
This was insane. I needed to push Chaerin away right now and end this ridiculous situation.
But my body was honest. The melting pleasure in my lower half raced up my spine and spread through my entire body, neutralizing every last scrap of resistance.
The forbidden thrill of doing it in someone else's living room, the time attack until Subin returned, and the sight of my twin sister looking up at me while obscenely working her tongue-
All of it mixed together into a pleasure I had never tasted before.
In the end I surrendered.
"...Just until Subin comes back."
The moment permission left my mouth, Chaerin's movements grew even bolder and more shameless.
"Nngh, chloop... chloooop...!"
She made satisfied little sounds as she swallowed me even deeper.
While she sucked she used her free hand to gently stroke the sensitive skin of my inner thighs.
That tiny stimulus made me realize all over again just how sensitive the muscles around my cock were.
It felt like every nerve in my body was concentrating around my dick.
Caught in the dangerous, thrilling pleasure of feeling like some kind of exhibitionist, I panted for breath.
Low moans escaped me under Chaerin's devoted oral service.
"Haa... Chaerin..."
And then I made a mistake.
I had sunk so deep into the pleasure that I completely failed to hear the sound of Subin returning.
"Huh?"
Subin's slightly startled voice.
I jerked my head up in shock and locked eyes with Subin, who had frozen in the entrance to the living room.
And Subin saw it.
In the middle of her own living room, the boy she had just shared her first kiss with was exposed, and his twin sister was greedily sucking his cock.
She witnessed the shocking scene with her own eyes.
-x-X-x-
Damn. I'm screwed.
My mind went completely blank.
Was there any situation worse than this?
Just moments ago, Subin and I had been wrapped in such a tender atmosphere, right on the verge of a confession.
And now she'd walked in on me getting a blowjob from my twin sister-right there in her living room.
My heart felt like it had plummeted straight through the floor.
I was certain Subin would explode in rage, or stare at me with pure contempt and scream at me to get the hell out.
No-crying seemed even more likely.
After all, she'd just been betrayed this horribly, in her own home, by the guy she'd only just thanked for becoming her friend.
But.
"Ah..."
Contrary to every expectation, Subin's reaction was surprisingly calm.
She was startled, of course, but nowhere near the stunned or devastated look I'd imagined.
Her eyes went wide for a moment; then she seemed to grasp the situation and smiled faintly.
"You were in the middle of sexual processing?"
Subin said it so casually that it almost sounded ordinary, then sat down at the table as if nothing were amiss.
"...Huh?"
Now it was my turn to be flustered.
"Oh-if the sexual processing makes things awkward, should I step out for a bit?"
She actually asked out of consideration for me.
I shook my head awkwardly. Having the homeowner leave just so someone could finish getting a blowjob felt even weirder.
"No, it's fine..."
Honestly, it wasn't fine at all.
The thought of Subin sitting right beside us, watching Chaerin and me perform this filthy act, made my face burn with shame.
Chaerin paused for only a heartbeat, then went right back to taking my cock into her mouth and working her tongue like nothing had changed.
That was when another piece of this world's common sense finally clicked into place for me.
If a man needed sexual processing, it had to be done immediately-anytime, anywhere.
It was as natural as a wife cooking dinner for her husband.
To Subin, the scene in front of her was a little hard to look at, but it wasn't some catastrophic crisis.
It was simply the perfectly ordinary sight of a man who urgently needed relief, and of Chaerin fulfilling that duty.
There was almost no jealousy in Subin's expression.
Just the faintest flicker of envy as her eyes drifted over Chaerin's head.
Still, she was clearly interested; even while pretending to study the board game, she kept sneaking glances our way.
-Slurp, schlick, slurrrp.
Every time those blatant, wet blowjob sounds spilled from Chaerin's lips, Subin's body gave a tiny jolt.
The tips of her ears had turned faintly pink.
The knowledge that someone was watching me get sucked made something inside me start to boil all over again.
Being conscious of Subin's gaze made my body tense up on its own. That tension brought a strange shiver that only amplified the pleasure, and my cock swelled until it felt ready to burst.
Chaerin sensed the change instantly and swallowed me even deeper.
My cock almost reached her throat, yet she didn't pull back. Instead she flicked her tongue against the underside of the head, giving me even stronger stimulation.
It didn't take long before I came deep inside Chaerin's mouth.
-Bluuurgh!
Even after having sex with the school nurse earlier, the volume of semen hadn't decreased at all.
If anything, the perverse thrill of Subin watching made me shoot even more than usual.
"Mmmp... gulp..."
Chaerin took the entire load in her mouth, then shot a quick glance at Subin for some reason-and instead of heading to the bathroom to spit, she simply swallowed everything right there.
As if she were showing off the fact that she'd just given the blowjob.
After that she performed a thorough cleanup blowjob, licking up every last remaining drop before finally letting my cock slip free.
"Haa..."
Service complete, Chaerin let out a satisfied sigh. She wiped her mouth with the back of her hand as if nothing had happened and returned to her seat.
"Alright, shall we finish the board game?"
The problem was me.
Even after shooting once so satisfyingly, my erection hadn't subsided in the slightest.
If anything, the combination of Subin's gaze beside me and the saliva Chaerin had left coating my cock made it swell even harder.
There was no way I could put my pants back on like this.
Standing there half-naked, I stared at Subin and wrestled with myself.
Should I even say it? What if she ends up hating me? Or... maybe Subin wants it too?
If I let this chance slip by, I knew I'd regret it. In the end I couldn't hold back any longer.
"Subin."
"Yeah?"
"Do you... want to try a cleanup blowjob too?"
The moment the words left my mouth, Chaerin's gaze snapped onto me. I felt a faint flicker of jealousy from her, but it wasn't severe.
Subin's face turned as red as a beet. She didn't refuse.
Instead, with an expression that mixed shy joy-almost as if she were grateful I'd offered her the chance -she gave a tiny nod.
"Y-yeah...!"
I stayed right where I was.
Subin came forward without hesitation, as though she'd been waiting a long time for this, and dropped to her knees in front of me.
She shot a quick, cautious glance at Chaerin, then shifted her eyes to my cock and swallowed hard.
In a posture so devout it almost looked like prayer, she gazed up at the thick shaft that still faintly glistened with Chaerin's saliva.
My long, heavy cock cast a shadow across her beautiful face.
The swollen head nearly brushed her neat forehead; the base sat lower than her tightly clenched chin.
Like someone staring up at a massive pillar, Subin's green eyes trembled with awe.
The sight of her entire face swallowed beneath the presence of my single cock made the urge to conquer her impossible to restrain.
At last Subin's cherry-red lips slowly parted and took my glistening cock into her mouth.
"Chuuup..."
Those very lips that had been kissing me only a little while ago were now wrapped around my cock.
That single fact alone made excitement explode through my skull like fireworks.
"Mmmp... lick... huup..."
Of course, since it was her first blowjob and she'd never practiced properly, Subin's technique was far clumsier and more awkward than Chaerin's.
Her teeth scraped now and then, and her tongue movements were stiff.
"It's okay. You're doing amazingly for your first time."
Still, I didn't hold back the praise as I stroked her soft blonde hair.
I'd already figured out that Subin was weak to compliments.
Just as I expected, every word of praise made her light up visibly and try even harder.
Her clumsy tongue work gradually softened; she strove in her own way to make me feel good.
She stopped simply sucking the shaft and instead stuck out her tongue, carefully licking from the head all the way down to the base, meticulously wiping away the saliva Chaerin had left behind.
She probably didn't intend it that way, but it felt like a possessive desire to erase every trace of Chaerin from my cock and claim it as hers alone-and that only made me harder.
For quite a while I simply stood there, surrounded by two beautiful girls, enjoying pure pleasure in someone else's living room.
When the clumsy cleanup blowjob finally ended, I praised her again for doing so well on her first try.
And I made sure to thank Chaerin sincerely for handling the sexual processing.
Her expression eased a little and she replied in classic tsundere fashion, "Well, it's nothing special."
Just like that, the two girls who had taken turns sucking one man's cock moments earlier behaved as if nothing unusual had occurred.
They casually ate the delivered chicken for dinner and went right back to enjoying the board game.
That night, when I got home, my phone kept buzzing nonstop.
It turned out to be a newly created class group chat. Everyone was chatting pretty lively.
When I sent a casual greeting, almost the entire class welcomed me warmly.
In the middle of that, a private message arrived from Subin.
Han Subin
Did you get home safe? Today was really fun. See you tomorrow, Sihyuk.
Because Chaerin had interrupted the confession flow, it looked like Subin intended for us to stay just friends for a while.
After finishing the short chat with her, I stared at the mountain of contacts and messages piled up on my phone and found myself wondering once again about the previous "Kim Sihyuk."
Before bed I took some time to start browsing through the traces of his past, little by little.
The conclusion I reached after reading was simple: he had been an extremely ordinary man.
Like any ordinary man of this world, he hadn't been particularly interested in women and had possessed almost no sex drive. Still, he occasionally ate meals with girls or chatted with them and received pocket money and gifts in return-relationships of exactly that level.
Nothing special stood out. What on earth had happened?
While I was lost in thought about Kim Sihyuk, I kept getting distracted by Chaerin's plump, tempting ass as she cleaned the house in dolphin shorts, and my cock kept getting hard at the worst possible moments.
As always, I swallowed a few of the pills from the hospital with water and went to sleep.
-x-X-x-
Subin's house.
Subin excitedly bragged to her mother-who had just gotten off work from the hospital-about how much fun she'd had playing with Sihyuk that day.
Her mother, Han Danbi, simply replied, "Is that so? Did you have a lot of fun?" and smiled warmly.
But deep in the night, after her daughter had fallen asleep, the atmosphere inside her room changed completely.
Beautiful blonde hair, a young and elegant face that could easily pass for Subin's older sister.
Danbi, dressed in an elegant silk gown, took out a sleek, unmarked laptop.
Fingerprint, iris. After clearing dual biometric security, a cold blue interface bloomed across the screen.
Project M: Status Monitor
OBSERVATION TARGET: KSH-073
Complex graphs of Kim Sihyuk's vital signs and hormone-level fluctuations filled the display.
Han Danbi scanned the received report with indifferent eyes, then typed a brief note into the confirmation field at the bottom.
Evaluation Entry
Sexual impulse-related hormone responses: active. Prefrontal cortex activity related to aggression control: within stable range. Maintain current drug therapy.
Her eyes were coldly sunken as she pressed the enter key. A dry sigh escaped her lips.
She closed the complex interface and opened a photo of her daughter on the desktop.
The bright smile of Subin-taken with Sihyuk on graduation day not long ago-filled the entire screen.
Her daughter's warm smile. As she gazed at that photo, Danbi's eyes wavered with complicated emotion.
Outside the window, the light in Sihyuk's house across the way went dark.
If it's for Subin's happiness...
She murmured quietly.
"It can't be helped. I did my best."
She turned off the screen and leaned back in her chair.
Beneath her closed eyelids, the face of her happily smiling daughter and the face of a man screaming in agony rose at the same time.
-x-X-x-
The next day, at the Academy.
Iseol noona entered the classroom. Dressed in a skirt suit, she looked mature and alluring.
"Alright, everyone take your seats. Starting from first period today, we will be learning oral service techniques."
Instead of her usual gentle, soft smile, she wore a solemn and serious expression. At the announcement that they would learn oral service techniques, the female students' faces brightened with anticipation.
Her voice rang through the classroom.
"Everyone, why is oral service the very first among the many caress techniques?"
Someone raised a hand and answered.
"Because it's the part men like the most?"
"That's not wrong, but there is a more fundamental reason."
Iseol noona began explaining like a proper teacher.
"The mouth is a basic organ for ingesting food to sustain life and for communicating with others."
"Accepting a man's genitals with that mouth means submitting far more deeply than mere ingestion or communication."
There was even a sense of reverence in her voice. I found it absurd, but the other women were all nodding with deeply impressed expressions.
After a long stretch of what was half theory class and half male worship, practical time finally arrived.
"Class president Kim Sihyuk, please come up to the podium."
At those words I rose from my seat and sat on the plush chair prepared for me on the podium. The women who had no idea why I had suddenly been called forward murmured among themselves, glancing at one another.
"Starting today, for every caress practice session, our class president Kim Sihyuk has agreed to personally participate as the male practice model."
At noona's declaration a quiet wave of exclamations rippled through the classroom. Disbelief and uncontrollable joy bloomed together on every face. Their gazes grew far hotter and more blatant than before, beginning to rake over my entire body.
Iseol noona watched her disciples' reactions with satisfaction before continuing.
"This is an enormous privilege and opportunity granted to our class. Students at other academy universities practice only with cold silicone models until graduation. Opportunities to learn by serving a man's precious body directly are almost never given."
She turned toward me, her eyes warm and full of respect.
"As you know, men inherently find it uncomfortable to expose their bodies to others."
"Despite that, Sihyuk has made this difficult decision to raise our class's learning efficiency and to help every one of you become an excellent wife in the future."
She turned back toward her disciples. Her voice grew even more solemn.
"The skin temperature of a living man, the minute tremors of muscle, the changes in breathing-we must feel and learn every one of these things directly if we are to be reborn as true first-class women."
She bowed deeply at the waist.
"Now, everyone, offer your thanks to Sihyuk."
The moment Iseol noona finished speaking, the twenty female university students seated before me all bowed in unison, expressing deep gratitude. Honestly, since I had harbored no such noble reasons at all and had only been thinking filthy thoughts, I felt a little embarrassed. Still, I managed a smile of my own and said something like, "Let's all work hard."
Once I finished speaking, everyone pushed desks and chairs to the back of the classroom in perfect unison. Then, as if they had rehearsed it, they neatly knelt before me. The sight of twenty women kneeling all at once and looking up at me was nothing short of a spectacle.
I was not yet erect, but I could feel their hot gazes locked on my cock. Under those stares I stripped off my pants and underwear. Some of the women gasped softly at the sheer fact that they were seeing a real cock.
"Whoa... so this is a cock...."
"Amazing..."
"I'm glad I was born...!"
"Hah, wah, hoo. This is really something else."
Only Iseol noona, Chaerin, and Subin-who had already seen my cock-kept relatively calm expressions.
"The first practice is observation meditation and the kiss of reverence. The goal is to cultivate both understanding of and awe toward the male genitals."
With Iseol noona's words a spotlight blazed down over my crotch. We had something like this in the classroom? Looking up, I could see lights and various devices mounted on the ceiling above the podium. Joyful murmurs and ragged breaths rose from every direction at the sight of my still-soft cock.
Noona took out a laser pointer and aimed it at me.
"This is the glans. The most sensitive place, where countless nerves are concentrated."
"Look at the thickness and direction of this vein. It is living proof that model Sihyuk's genitals are extremely healthy."
There was even pride in her voice. She sounded like a curator introducing the finest masterpiece in an art museum. The women gazed at my cock with a variety of expressions.
"We will now begin five minutes of meditation."
Iseol noona spoke in a low, measured tone.
"You must not think of the genitals before your eyes as an ordinary body part. Never take them lightly! This is the man you must serve. Silently repeat to yourselves what kind of beings you are and how you ought to treat a man."
The classroom fell utterly silent. Only the shallow breathing of more than twenty beauties and my cock -gradually warming under the weight of every gaze-existed in the room.
When the meditation ended, Iseol noona announced the next exercise.
"As you just learned in theory, it is time for the kiss of reverence upon model Sihyuk's cock. I will demonstrate first."
With every eye fixed on her, Iseol noona stepped forward onto the podium. She sank at my feet and, without the slightest hesitation, assumed a perfect dogeza. Quiet admiration burst from the women at that flawless posture of submission. Her suit skirt pulled taut, fully revealing the curve of her hips. She carefully lifted her head and lightly pressed her lips to the tip of my cock before withdrawing.
-Smack.
At the warm, soft sensation my cock twitched in response.
"If teeth make contact or breath feels too strong, it can cause discomfort. Therefore you must do it softly, filled only with respect."
Signaled by her kiss, my cock began to harden and swell in an instant. At the sight of it ballooning to an enormous size the women's eyes grew even wider. Iseol noona wore the unguarded, excited expression of a thrilled female. Then she kissed the tip of the swollen glans-the very urethral opening. When a bead of precum welled up she flicked her tongue out and licked it away. She continued down the shaft, kissing as she went, and carefully kissed each heavy hanging ball in turn from right to left.
"Now it is your turn."
When Iseol noona's demonstration finished, the female students came forward one by one. First was the vice president, Cha Ayeong-a cold beauty with long black hair and feline features. She always wore a haughty expression, yet the moment she prostrated before me in dogeza she looked utterly submissive, and it was hot. Ayeong left kisses all over my cock exactly as Iseol noona had done.
Unlike her icy image, her lips were scorching. Next was Chaerin. Unlike her usual grumbling self, perhaps because this was class, she prostrated politely. Chaerin's kisses were short but sincere; since that mouth already gave me regular sexual-relief fellatio, I relaxed a little. Then came Subin's turn. Face flushed with embarrassment, body trembling, she knelt before me. When her lips touched the glans, yesterday's sweet sensation flooded back and my cock pulsed even more fiercely. She startled, but that pure reaction only excited me further. Yeji approached with a bright smile and, unlike the others, kissed a little more intimately, making soft sounds; a smear of precum clung to her lips.
After that the cock-kisses of nearly twenty female students continued one after another. Only Baek Hayeon stayed out of it, quietly watching us from the back of the classroom. The women prostrated, pressed their lips to my cock, and looked up at me with eyes full of awe, respect-even love. Would I ever experience something like this again in my life? Unlike the cheap release of jacking off, a deep spiritual fulfillment and overwhelming satisfaction swept through my entire body. For the first time I understood just how powerful a pleasure it was to be respected and loved by so many women.
The women who had kissed my cock could not hide their own excitement and joy either. Each one spent well over a minute carefully finishing her service.
"Holy shit... I really kissed a guy's cock...."
"It's on a completely different level from imagination! It's alive!"
"Did you taste the precum? Yeji sucked it all up so I didn't get any."
"I should have smelled it a little longer...."
Amid their excited whispers the bell rang, ending first period.
When second period began, Iseol noona returned to the cool face of a strict teacher.
"The tongue is a muscle. You must use that tongue not merely as an organ for tasting but as a tool for men."
"If the force you put into the tongue is too strong the man feels pain; if too weak he feels nothing."
Practice followed at once. This time, however, I had nothing to do.
"The first drill is tongue-muscle training. Try tying a cherry stem with the tip of your tongue. It is highly effective for building both strength and precision, so practice it regularly on your own as well."
Everyone stuck out their tongues and began wrestling with cherry stems. Slightly protruding tips, white teeth flashing between red lips, and utterly serious faces combined into a strangely erotic scene. The women trained at their seats-tying stems or rapidly flicking their tongues up, down, left, and right. It looked comical, yet no one laughed. Every single one of them was deadly earnest.
"Next is temperature-control training."
Iseol noona handed out oral thermometers one by one.
"A man's genitals run slightly cooler than normal body temperature. Ideally your tongue should stay a little warmer than that-warm, never hot."
"Preferred fellatio temperatures differ from man to man, so you must practice precise control of the temperature inside your mouth in one-degree increments."
The women began practicing by alternately holding cold water and warm water placed at the front and back of the room. When noona ordered thirty-six degrees they hit thirty-six; when she ordered thirty-seven they hit thirty-seven.
"Before fellatio a woman must prepare her mouth in advance to the temperature her man prefers. For that you need both hot water and cold water."
Noona passed on tip after tip, stressing how crucial the amount of water held in the mouth really was.
Third period was devoted to controlling the texture of the tongue. Noona explained that the exact part of the tongue used could produce completely different sensations.
"The tip delivers sharp, thrilling stimulation, while the broad surface wraps and soothes."
"You can also regulate the amount of saliva to create varied textures that shift between dry and wet. This is the texture-variation technique of fellatio."
The women threw themselves into the drills exactly as taught-drawing in breath to dry the mouth, then stimulating the jaw to flood it with saliva, over and over. With nothing particular to do I simply watched. Even though they were practicing into empty air, their expressions stayed deadly serious. Some closed their eyes tightly while they worked their tongues. Those techniques will eventually be used on me, the practice model. Just imagining it made my lower body grow tight again.
In the final fourth period before lunch, Iseol noona once more projected an enlarged photograph of my cock onto the screen.
"Our last morning period will be devoted to glans caress techniques. We will practice them on Sihyuk shortly, so pay close attention."
The women's eyes sparkled brightly once more.

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."
