Position Practice
We gathered in the auditorium for the entrance ceremony, then were assigned our individual private dorms where we'd be living for the next three years.
Aside from our homeroom instructor Han Yejin establishing discipline, the first day passed without anything particularly noteworthy. It was the first day, after all — they seemed to be going easy on us without any real training, probably for the mental care of the men still reeling from the shock of enrolling at Seongmugyo.
Still, men were men.
I lay on my bed and thought.
Damn... but these facilities are no joke.
For one thing, this world was set in the distant future, so the technology was highly advanced. For someone who'd lived in the 2020s, it was a pretty fascinating sight. Unmanned cleaning robots floating through the air, holographic AI guidance systems — it was hard not to be impressed. A future world a hundred years ahead, with all its technological progress, had its own sightseeing appeal even for someone as indifferent as me.
Of course, that same technology also contributed to sexual activity in various ways.
Suddenly, tomorrow's events came to mind.
It's probably tomorrow, right?
The C-Class curriculum was designed by our C-Class instructor, Han Yejin. And tomorrow, the events I'd read about in Chapter 1 would play out in reality exactly as written.
Just thinking about it made my cock throb and heat up on its own. I was definitely looking forward to it.
I woke early, changed into my uniform, and headed for the classroom. The uniform was blue with a red necktie.
I arrived at a leisurely pace right on time, only to find that the other men — and even Instructor Han Yejin herself — were already there. A quick check confirmed I wasn't late, so I took my seat promptly.
Once I sat down, Han Yejin spoke.
"Everyone's here."
Her voice still carried that same forced, throat-tightened edge.
"Good. Now that you're all assembled, we will begin the cock measurements."
"Excuse me?"
"Cock measurements?"
Every man in the room went blank at Instructor Han Yejin's words. Cock measurements? Their faces said it all — what kind of vulgar measurement was that?
"I-Instructor, are you serious?"
"C-Come on, measuring our cocks is a bit much..."
"Silence."
Han Yejin's heavy single word rolled through the classroom. Quiet and calm as it was, the voice carried force.
"Did I not tell you? You are cocks. You failed to fulfill your duties, and now you want to talk about human rights?"
"..."
Not a single man opened his mouth. Most of them wore faces full of fear. Only now did it seem to sink in that they had actually come to Seongmugyo.
Honestly, even knowing what was coming, having it shoved in my face like this was a bit absurd. The way she just casually spat out the word "cock" with zero shame...
"If you understand, all of you stand! Unzip and take out your cocks. Begin!"
"B-Begin..."
The men rose slowly from their seats with wilted faces. Most of them dithered and hesitated, reluctant to lower their zippers. At that sight, our instructor Han Yejin flared up again, her expression turning fierce.
"I told you — refusal of training will result in punishment. Since this is the first day, I'll leave it as a warning. Disobey my orders again and I will punish you without hesitation. Do you understand?!"
"Y-Yes, ma'am!"
Only after Han Yejin's roar did the men finally start unzipping. I had already lowered mine long ago.
"All of you, at ease!"
The male students shuffled into an at-ease stance, still fidgeting.
"From this moment, maintain absolute stillness! Understood?"
"Understood!"
"Good. Then."
Han Yejin pulled on a pair of rubber gloves and began moving from one man to the next, examining their cocks. Without the slightest hesitation she slipped her hand into each zipper, pulled the cock free, and started jiggling it.
"Ugh!"
"Hmm..."
The men who were already hard could only wear faces of pure humiliation. Han Yejin, for her part, seemed genuinely interested only in measuring size — she jotted the measurements onto a form she carried and simply moved on to the next seat.
Then it was my turn.
Swoosh—
Once again, Han Yejin calmly slipped her hand into my zipper and drew my cock out. But in that brief instant, I saw her eyes go wide.
"Huh..."
A faint note of admiration colored her voice and face. Then she took hold of my cock and began to shake it. Naturally, I got hard.
"Th-This is..."
A flustered edge crept into Han Yejin's voice. She looked at me and spoke.
"What an excellent cock."
"Thank you."
I answered flatly. That reaction must have caught her off guard — she went blank for a moment.
"Ah..."
Then she snapped back to herself, her face twisting into something demonic as she opened her mouth again.
Women in this world, as anyone would know, were completely cock-obsessed. With men so extremely scarce, it was inevitable. But the instructors at Seongmugyo were different. They were elites among elites, put through rigorous state training — women who, through sheer insane willpower, had the concept of "restraint" installed in them.
Which was why, once she recovered, Han Yejin started clamping down on discipline again.
"And yet you possess a cock this fine and still failed to fulfill your duties?"
"I'm sorry."
"Does 'sorry' end your time at Seongmugyo?!"
"No, ma'am! I will correct it!"
"How do you intend to correct it?!"
"By working as hard as I can! I'll make women happy!"
At my words, Han Yejin's expression blanked out again. Clearly she hadn't expected that answer. I may not look it, but I was a military veteran — predicting what a superior wanted to hear was second nature. This kind of discipline-setting was almost cute. It wasn't even that bad to begin with. How could a situation where a beauty like Instructor Han Yejin was holding my cock possibly be bad?
Once she recovered again, Han Yejin shifted back to a stern, composed expression and spoke.
"All of you, attention! Applause for Shin Jinho!"
Clap! Clap! Clap!
An unexpected turn. Han Yejin clapped the loudest, and the male students followed her orders and started clapping as well. She continued.
"Shin Jinho's statement was excellent. Going forward, maintain that mindset and complete your Seongmugyo education properly."
"Yes, Instructor!"
"However — whether that resolve is genuine, I will be watching during practical training."
"I'll fuck hard— I mean, I'll do my best."
She simply nodded at my words without comment and moved on to the next student, Kim Yuseong.
I thought to myself.
Holy shit, I almost came.
Honestly, when Instructor Han Yejin had been stroking my cock earlier, I'd nearly finished. Looks like this Shin Jinho body really was a premature ejaculator.
After measuring every cock in C-Class, Han Yejin addressed the men.
"All right. From this moment we move to the auditorium! Everyone out into the hallway and form a single file! Begin!"
"B-Begin!"
At her command, the C-Class men poured into the hallway and lined up single file. Han Yejin stepped out as well and began scanning the line of men. Then she opened her mouth — and what came out was different from the line I remembered from the novel.
"Shin Jinho, step out to the side."
"Huh? Me?"
I looked at Han Yejin with a puzzled face. As far as I remembered, she was supposed to call Kim Yuseong here, not me.
"Is that insubordination?"
"N-No, ma'am."
I stepped out of line with a slightly awkward expression. Han Yejin continued.
"From this moment, Shin Jinho is the class president of Class 1-C."
"Ah..."
There it was — the line I'd expected, just with the wrong person. In the novel, Han Yejin appointed Kim Yuseong as class president. Here, she'd chosen me instead.
Ah, shit. Did I overdo it...?
Class president. An insanely annoying position. Even during reserve training I'd always managed to dodge being team leader, and now I got stuck with it here?
For the first time since arriving in this place, I felt genuinely dejected. Han Yejin paid zero attention to my expression and kept talking.
"From now on, Shin Jinho will stand at the front of the line and lead the class to the auditorium as-is. Understood?"
"Um... what about you, Instructor?"
One of the men asked without reading the room. Surprisingly, Han Yejin answered the question with unexpected patience.
"The auditorium training is not my responsibility. Wait there and the assigned instructor will find you. Understood?!"
"Yes! U-Understood!"
At that, I looked at Han Yejin in silence for a moment. So the scene from Chapter 1 was about to play out after all.
"Then we move to the auditorium! Begin!"
"Begin!"
And so I led the C-Class students toward the auditorium.
Like most schools, the auditorium doubled as an indoor gymnasium. Meaning this was where the physical stuff would happen.
The auditorium was bright and empty. Well, with only ten men in a space this large, that was only natural.
"What kind of training do you think it is?"
"Ugh, I'm a little nervous..."
"It's the first day, so they probably won't make us do anything crazy."
Weaklings. The way they talked was so soft and feminine it was almost nauseating. I wasn't exactly a man's man myself, but guys who spoke like that still rubbed me the wrong way.
"What kind of training do you think it is, Jinho?"
Kim Yuseong came up beside me and asked. I answered flatly.
"Sex training, probably?"
"Haah... don't say scary things like that."
I casually rolled my eyes toward him. He was just as reluctant as the other men, but something about Kim Yuseong was different. The others feared women. Kim Yuseong seemed more like he was averse to them — the way you'd look at a cockroach.
Something must have happened in his past.
It was a reasonable suspicion. He seemed like a normal guy, yet the moment women entered the picture he showed extreme aversion. That wasn't an emotion born of fear. If I had to name it, it was closer to disgust.
Well, not my problem.
He was the original protagonist — the story would sort him out as it progressed. It wasn't something I needed to worry about right now.
That was when it happened.
"Looks like everyone's here."
A voice I'd never heard before. A deep, solid male voice. Every man turned to look behind them.
There stood a male instructor with a tall frame, rugged muscle, a clean-cut sports hairstyle, and a striking presence, approaching the students while pulling a black suitcase behind him.
Damn, how tall is he...?
At least 190? No, closer to 200 centimeters? On top of that height, the well-proportioned, solid muscle only amplified his masculinity. He looked like the ideal man from my original world. I wanted muscle like that myself.
"All of you, form two columns. Begin."
"B-Begin."
At the sudden appearance of this new male instructor, the men scrambled into two columns. There was no threat in his voice, no barked command — but with a build like that, the words carried an irresistible force.
The newly arrived male instructor stood before the students and introduced himself.
"I am Instructor Park Jinwook, in charge of this position correction training. Nice to meet you, first-years."
His expression was calm, his voice free of intimidation. More than anything, the fact that the instructor was a man — combined with how the female instructors had been barking discipline at them earlier — meant the students' gazes toward Park Jinwook weren't particularly hostile. In fact, the novel had described him as the most popular instructor at Seongmugyo.
"All right. From this moment, we begin the position correction practical."
"Position correction?"
"That's right. Anyone here with experience?"
No one raised a hand. Of course not — if they'd had experience, they wouldn't be here. This place was full of cocks that had never even left the nest.
"That's fine. No need to feel discouraged. However, during the training process, I'd prefer you not disobey this instructor's instructions. Honestly, I don't want any of you ending up in the Punishment Room either."
Park Jinwook spoke with a gentle smile. The tension on the men's faces eased, and you could see them opening up to him.
Then one of them, struck by curiosity, asked a question.
"Instructor, what exactly is the Punishment Room?"
"Exactly what it sounds like. A place for correcting delinquent students who break the rules or refuse training. And there's no need to be so tense. As long as you complete the training properly, you'll never set foot in the Punishment Room — in fact, over three years at Seongmugyo, it's the hardest place to end up in."
I actually wanted to experience that Punishment Room once. Should I ask later if I could try it out of curiosity?
"All right, then."
Clap—
Park Jinwook clapped his hands to draw their attention and looked over the students.
"The position this instructor will teach you in your first practical is the missionary position. In terms of difficulty, it's the easiest position — but for men without stamina, it can still be tough. Any student I judge as unqualified during this practical will undergo physical conditioning with me. Any objections?"
There couldn't be any. It wasn't punishment — just physical training. The male students answered with one heart and one mind, free of complaint.
"None!"
"Good. Then we will now begin missionary position practical training."
With that, Park Jinwook laid the suitcase he'd been pulling flat on the floor where the students could see it. Every man was staring at it with puzzled faces when he opened the suitcase for them to see.
In that instant, horror flooded their faces.
"A-Are you insane?!"
"Wh-What the hell is that?!"
Inside the suitcase was a mannequin. A mannequin covered head to toe in black latex, no less.
But it differed from an ordinary mannequin in one key way: it had no arms and no legs. Its face was round like an egg ghost, with no nose and no eyes — the only feature was a circular open mouth, shaped as if designed for a cock to go into. Finally, a U-shaped metal bar — essentially a handle — was attached to the crown of its head and to either side of its waist.
The slender waist and mountainously full breasts made it clear that this featureless latex rubber mannequin was female.
But for the students, this sight was far too stimulating — a genuinely shocking spectacle.
"A-Aaaah!"
"Oh my god..."
Thud—
A few of them went completely vacant, and a few more had their legs give out, collapsing to the floor. That was how shocking the sight was to them.
"I-Instructor?"
In the middle of all this, Kim Yuseong — who was at least still managing to keep his composure — asked Park Jinwook with a tense face.
"That thing in the suitcase... is it a real person?"
"..."
At the question, Park Jinwook surveyed the students with a grave expression, as if gauging their reactions. Then he let out a short snort of laughter and spoke.
"You think it'd be a real person?"
"Haah..."
"You scared us, Instructor."
The male students relaxed at Park Jinwook's words. He continued.
"This is a sex practice robot developed by our Seongmugyo research lab. Model designation: HYJ Model 1. See the number 1 on its forehead?"
Indeed, a large white number 1 was written prominently across its forehead. Park Jinwook then grabbed the handle on HYJ Model 1's head and lifted it up so the students could see clearly. The torso of HYJ Model 1 dangled and swayed under that powerful grip. Lifting that thing with one hand — those were some serious muscles.
"This HYJ Model 1 was made for problem students like you. The lack of a face was designed out of consideration for those of you who are averse to women. However—"
Suddenly, Park Jinwook pinched HYJ Model 1's nipple with the fingers of his free hand. The next moment, he yanked and twisted it.
At the same time, a woman's voice burst from HYJ Model 1.
"Nngh! Aghkk!!"
"Hear that? It still has a voice unit installed so you can get the sense of a real woman. When stimulated, it lets out sounds. Also—"
Park Jinwook set HYJ Model 1 back on the floor. Then he lifted one foot and pressed down hard on its chest.
Squish—
"Hngh!"
"As you can see, the body reacts as well."
Just as he said, HYJ Model 1's body trembled violently under the pressure on its plump breasts. Through all of this, Park Jinwook continued his explanation with perfect calm.
"HYJ Model 1 is a robot that produces voice or movement in response to physical contact or stimulation. This instructor's first practical will evaluate you based on this robot's reactions. Any questions?"
"May I ask about the exact evaluation criteria?"
That was my question. Park Jinwook answered kindly.
"Making HYJ Model 1 cry out with the loudest moan, or thrash about the most violently — those are the criteria. That's all. Any other questions?"
There were none after that. The students simply waited for Park Jinwook's next words with slightly less tense faces.
Confirming there were no more questions, Park Jinwook continued.
"Good. Then — is there anyone who wants to go first for the practical? If not, this instructor will assign the order at his discretion—"
"I'll go first."
"Hm?"
Park Jinwook looked at the student who'd raised his hand with a face of genuine surprise. In ten years as an instructor, he had never once had a student voluntarily raise their hand and offer to go first during the very first training session.
"Huh... this is unexpected. Student's name?"
"Shin Jinho."
"Excellent, Student Shin Jinho. This instructor will award you additional points separately. Everyone, applause!"
Clap! Clap! Clap!
The male students clapped along with Park Jinwook. Honestly, I wasn't sure this was something that deserved applause — but so what? As long as I was happy, that was enough.
And my reason for going first was simple. I just didn't want to stick my cock into a hole some other guy had already used. Even with a condom, it was a physiological thing.
"All right. Student Shin Jinho, follow this instructor. The practical will take place in the individual practice room located on the left wall of the auditorium."
"Yes! Understood!"
I answered in the loudest voice I'd used since arriving at Seongmugyo, and followed Park Jinwook.
