Position Review (2)

Besides the sex robot (Han Yejin), the carrier held a few other things.

This looked like the instruction manual Instructor Park Jinwook had mentioned earlier, and that one seemed to be a decibel meter.

I pulled out the user manual first and started reading.

Judging by the contents, it was less a user manual and more a list of warnings.

How to put it…

It felt like a manual slapped together on the fly. Like something they'd just written and printed out moments ago.

Well, Seongmugyo had never dealt with a situation like this before, so Park Jinwook had ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠probably drafted it on the spot.

I could more or less tell what they were worried about, so I carefully folded the manual back up, tucked it into the carrier, and turned my gaze back to the sex robot.

Looking at it like this, it really does look like a real doll.

An inorganic mannequin. A genuine real doll with no arms or legs, its entire body sheathed in latex. Completely motionless, no limbs at all — the impression was strong.

Advanced technology really was something else. How had they made the arms and legs vanish so seamlessly?

If I remembered right, that was where the invention called a Space Ring had been installed. That was what made this pseudo-amputation possible.

Anyway, Han Yejin's current appearance was… well, she looked for all the world like a sex doll that existed solely to relieve a man's lust. Of course, she was only wearing this suit as an instructor to educate a male student in sexual practice — but the direction was close enough, so I decided to give it my all.

I stripped off my pants first and freed my cock. No matter how many times I looked at it, that thing alone was massive.

Climbing onto the bed like that, I decided to skim the position textbook once.

"Let's see…"

Hmm… most of these were positions I already knew. No real need ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to consult the textbook.

I tossed it back into the carrier and reached for the sex doll's breasts. The moment my hand made contact—

A flinch.

The sex doll reacted, just slightly. I touched them again. The feel was incredible — smooth surface, soft give, and a warmth that felt almost like real human skin. Maybe later I'd use these breasts as a pillow.

Wow… damn.

After kneading and caressing them for a while, I pulled the doll toward me and wrapped my arms around it, wanting to fondle those breasts properly. The sex doll's back pressed against my chest, and from that embrace I started working her breasts again.

"Nngh♡!"

A faint moan slipped from the sex doll's mouth each time — muffled and thin, thanks to the stopper fitted between her lips.

But what's this?

My eyes went to the plug in the sex doll's mouth. It definitely hadn't been there during the practical session. Something like the drain stopper you'd find in a bathtub? It looked like it would come free if I pulled.

I gripped it and tugged.

Pop!

With a soft pop, the plug came free easily. Just an ordinary decorative piece, apparently.

At the same time, I suddenly got curious about the inside of this sex doll's mouth. During the practical earlier, it had been covered with some red rubber membrane — was it still like that?

I peered into the sex doll's open mouth. My eyes went wide on their own.

"What the hell is this?"

The open mouth was not a human mouth. The surface was studded with little nubs and ridges — if I had to give an example, the interior of an onahole would look something like this. Curious about the texture, I touched it. Silicone.

As I worked my index and middle fingers around inside, a voice spilled from the sex doll's mouth.

"Ahgu— guwahk—"

"Huh…"

A thought struck me unbidden. If the inside of her mouth was lined like this, did that mean Han Yejin was forced to keep her jaws open, biting down on this silicone the whole time? I couldn't help wondering how she was even breathing — there weren't any visible nostrils on the face surface either.

And looking into that mouth, something I suddenly wanted to try came to mind.

I laid the sex doll back on the bed, straddled her stomach, and nestled my cock between her breasts. They were big enough to make it possible. Gripping both breasts with my hands, I squeezed them inward so they wrapped around my shaft.

"Eughk! Ahguah! Haa! Haa!"

"Nice. Shall we?"

With those words, Jinho's hand reached for the handle attached to the sex doll's head.

Having put the sex-practice suit back on for Shin Jinho's review session, Han Yejin was thinking to herself.

Haa! Haa! I never thought he'd pull me into his arms and start fondling my breasts.

It wasn't something an ordinary man would do, and there was no real reason for it either. Which only meant that this Shin Jinho kid was a genuine oddball.

Right now she was disguised as a sex robot, and Shin Jinho didn't know that. (He actually did.) And he was holding that sex robot in his arms, caressing its breasts.

Instead of practicing the positions he was supposed to, he was doing breast play? That was a scenario Han Yejin had not anticipated. And for good reason.

Haa! Haa! This Shin Jinho kid… it really feels like he's dealing with an actual woman.

Not treating her as a mere practice doll, but practicing as if he were facing a real woman.

What a remarkable kid… nngh!

As the instructor in charge, Han Yejin could only feel proud of what he was doing. Setting position practice aside, his actions looked like he was sincerely learning how to handle a woman.

The slight problem was that Han Yejin had no immunity to this kind of thing. She'd learned about it at the training camp, of course, but with ordinary men it was rare for the male to take the lead during sex. In other words, the present situation was a fresh stimulus for her.

Nngh! Th-this kid. Has he felt up breasts somewhere before?

Why was he so good at this? The way he worked her breasts was no amateur job. This was not the touch of someone who'd only done it once or twice.

Where Han Yejin was mistaken: for Jinho, too, this was the first time he'd ever touched a woman's breasts. But the act of kneading them was packed with sincerity, care, and raw desire — that was what made it possible. He was caressing her with the thought of how to make Han Yejin feel good.

Then it happened.

Haa! Haa! What?

Shin Jinho stopped the caress, suddenly set her down from his embrace, and laid her back on the bed. Han Yejin figured he was finally about to start position practice and steeled herself.

I need to get my head on straight.

His premature ejaculation was a shame, but that only made the destructive power of Shin Jinho's cock that much greater. Compared to his small frame, the size of it was overwhelmingly massive. Even an elite instructor like Han Yejin felt tense facing that ominous girth.

Come on, then.

Having finished preparing herself mentally, Han Yejin was ready to take Shin Jinho's cock — when his actions completely defied her expectations.

Huh?

Shin Jinho suddenly straddled her stomach. At the same time, he began laying that oversized cock between her breasts.

What? Is he seriously doing this?

Breast onahole. That was clearly what Shin Jinho intended. The technical term was paizuri. And it was an act you couldn't perform alone — one that actually required a woman's lead. The fact that he was practicing it ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠anyway meant…

This Shin Jinho kid… is he seriously thinking all the way to having sex with a real woman?

One of Seongmugyo's educational ideals was to change the way men looked at women — to reshape their perception into something like that of the men who existed only in the historical records of a distant past. That was Seongmugyo's ultimate educational goal.

But it had always been impossible. Not a single graduate had ever married a woman. Men in that top one percent never ended up at Seongmugyo in the first place.

Shin Jinho was different. He seemed genuinely ready to face a woman. Sex practice, caress practice — equals marriage prep. That was how Han Yejin saw it.

Nngh! Haa! Haa! I'd love to help if I could, but…

In her current state as a sex robot with no arms or legs, there was nothing Han Yejin could do to assist. More than that, practice and the real thing were different. Even if she'd had her limbs, if she took the lead and helped him, Shin Jinho might feel the gap between practice and reality and develop an aversion. (No. He would love it.)

And yet here he was, admirably trying to do a breast onahole all on his own. A smile slipped out of Han Yejin before she could stop it.

Fine. Use me however you want.

Right now she was nothing more than a sex robot. All she could do was lend her body to help him practice all sorts of things.

Then it happened.

Huh?

Something Han Yejin had not expected at all. Shin Jinho suddenly grabbed the handle on her head and pulled. The head of his massive cock bumped against her lips with a soft thok.

D-don't tell me?

Han Yejin knew exactly what he was about to do. Fellatio. Was he seriously planning to practice paizuri and fellatio at the same time? A method only someone with a cock as oversized as Shin Jinho's could even attempt?

B-but fellatio was a high-difficulty act you only learned in the third year—

Th-that's still too much for a first-year, a brand-new freshman at th— ughp!

Regardless of Han Yejin's worries, the massive cock pushed into the hole of her mouth.

"Uguup!!"

"Haa… so this is a blowjob."

Separate from Han Yejin's fretting, Shin Jinho was just smiling. Of course, with her vision blocked, Han Yejin couldn't see it. Holding the handle on her head, Jinho simply rocked it back and forth, enjoying the fellatio.

"Uup♡! Uguup♡! Ubuup♡! Ubuuubuup—————!!"

Han Yejin's moans ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠filled the room.
