Episode 1. Tutorial.
Clop. Clop.
A man with a big frame and a hefty build, like a fat bear, calmly walks through the forest. Every tree making up the forest is so enormous that even craning his neck back until it hurts, he can't see the top.
But after about thirty meters, the surroundings begin to change.
"...Ah, seriously, this feels like some kind of fucked-up dream."
Jaeseok, who had definitely been walking through a forest, let out a hollow laugh as he realized he was walking down a hallway inside some building.
It looked like the corridor of an old motel. Or maybe an officetel. Doors lined the long hallway, one after another, but the corridor stretched endlessly in both directions, and there was no sign of the outside.
"What a bizarre place. Am I going to run into a succubus if I keep walking?"
But as he continued onward, what appeared was a single door standing open by itself.
And waiting for him at the entrance was a woman.
"Oh, you're here? Let's see, your ID is... Jaeseok-nim, right?"
"Huh? Uh? Ah, yes."
Jaeseok had reflexively raised his sword and shield, expecting a monster attack, but the woman's unfailingly polite demeanor left him hesitating as he looked at her.
Absurdly, two lines of text hovered above her head.
[Level 1. Normal.]
[Prostitute.]
When he checked the text above the black-haired woman, new text appeared.
[Concept confirmed.]
[This is the Lust area.]
'What the... Is this a monster?'
The prostitute guided the bewildered Jaeseok.
"Don't just stand there. Come in before someone sees you."
"Ah, yes."
Jaeseok followed her inside with a vacant look.
Click.
As she closed the front door behind him, he looked around the apartment. There was a small bathroom right beside the entrance, a desk piled with dolls by the window, and a bed and computer beside it.
Judging by all the everyday items that made the place feel lived-in and modern, it seemed less like a motel and more like a studio officetel.
"Now, take your clothes off."
As the prostitute spoke, text appeared before his eyes.
[Natural Request (Normal) activated!]
[Your mental strength is extremely high! You resisted Natural Request (Normal)!!]
'Resisted? What did I resist?'
Jaeseok didn't understand what was going on for a moment. He looked around, then suddenly froze. He'd spotted something unexpected on the bed.
'...A garbage bag?'
"What are you doing? You're not planning to do it with your clothes on, are you?"
The being, whether human or monster, asked him a question, but the sight was so unexpected that Jaeseok asked her one in return.
"I mean, no, but why did you put a garbage bag on the bed?"
"What are you talking about? There's nothing on the bed except the blanket."
"No, it's right there, and it's huge..."
"Are we not having sex?"
At her slightly irritated tone, Jaeseok hesitated.
And only then did he realize.
'Sex?'
Once the obvious fact dawned on him, he finally took in the woman's appearance.
She was wearing a black silk outfit. It was commonly called a slip dress, and since it was meant to be worn as sleepwear, it was extremely revealing.
'We're having sex...? Me?'
He stared at her.
Truthfully, she wasn't a great beauty.
As a [Normal]-rank woman, she was the kind of person you could see anywhere if you only judged her by her face. An ordinary woman you might see at a convenience store or bakery.
But her figure was anything but ordinary.
Her slip dress left her shoulders bare and showed off her chest, her ample breasts nearly spilling out of the garment.
Even Jaeseok, who didn't know much about women, could tell at a glance: D-cup or bigger!
"Hey. You can't do it with your clothes on."
At her matter-of-fact words, Jaeseok thought:
'Wait. Isn't this disarming myself?'
Come to think of it, she was a [Monster], and this place was called a [Labyrinth].
He had no idea what might happen if he carelessly put his weapons down—
"Ah, yes! I can't do that!!"
Thud! Clang!
But Jaeseok had already tossed aside the sword and shield he was holding.
A man ruled by his lower half is a truly heartbreaking creature.
"Uh, this... Ah, so this is how you do it."
Next, he took off his armor. Naturally, the fitted armor didn't come off easily, but once he tried, it wasn't impossible.
Clang! Rumble.
The roughly removed leather armor rolled across the floor.
Only then did a smile blossom on the prostitute's slightly irritated face.
"Hehe. You don't have to rush so much, you know. I thought you weren't going to do it."
"Of course I am."
Jaeseok was a virgin.
That didn't mean he'd never even held a woman's hand. He had burning desire, and when people have desire, they find a way to satisfy it somehow. That's just human nature.
He'd actually had a casual girlfriend, and he'd tried to have a one-night stand.
But every one of those opportunities had ended in failure.
'Sorry, Jaeseok. I don't think this is going to work...'
'Ah! Ugh! Shit! I can't do this. Get it out!'
He'd gotten as far as undressing, kissing, and even trying to penetrate... But in the end, he'd never managed to do it properly.
His ex-girlfriend, who'd been having a pretty good time, and the club girl who'd said, "Bigger is obviously better!"—neither could take his member.
Even his attempt to pay someone to take care of it had failed.
Jaeseok remembered the man who'd pulled out his phone and pointed to a list of terms.
[Clam, interior design, suckers. No big-dick customers.]
'What... does that mean?'
'Clam means guys who finger our girls' holes like crazy. Interior design means guys who put beads and stuff in there. Suckers are the ones who suck on their holes and nipples for ages. And customers means the last one.'
'Big dicks... are banned too?'
'Of course they're banned! You want to take responsibility if our girls get torn up down there!? Even if they don't tear, if they're totally drained, that's the end of business for the day!'
Jaeseok's member was abnormally large. The length was a problem, but the thickness was an even bigger one!
His school-days nickname had been [Afkill], for crying out loud.
Of course, when you actually saw it, it was thinner than an Afkill can, but its length of over twenty-five centimeters caused problems not just in everyday life, but in his sex life, too.
"Excuse me."
Jaeseok spoke before taking off his pants. It was a defense mechanism born of his repeated failures.
"What is it, customer?"
"Well, I'm a bit big. Will we still be able to have sex?"
"Hehe. Is that what you're worried about? Don't worry. I'm not an amateur, and I won't back out over something like that."
At the confident look on her face, Jaeseok finally made up his mind.
Then he pulled down his pants.
Thud.
His heavy member hung down and slapped his thigh. Like a boa constrictor. The Afkill, which he'd had trouble taking out even in front of a urinal because of his friends' teasing, had finally made its appearance.
"..."
The prostitute's mouth fell open as she stared.
"It's a bit big, right?"
"Th-That's true. Are you hard?"
"If I were hard, it wouldn't be hanging down like this. I'm not some old man."
"It's that big when you're not even hard?"
She spoke as if she couldn't believe it, but honestly, its current size didn't quite live up to the name Afkill. It was about the size of a can of mousse, at best.
But a woman was standing right in front of him, her chest completely exposed, staring at his member.
Hng.
Erec.
Ted.
'Ah, shit.'
Thump.
The head of his penis smacked against Jaeseok's navel. The prostitute watched in surprise for a moment, then spoke.
"Uh, let's start properly with fellatio first."
[Natural Request (Normal) activated!]
[Your mental strength is extremely high! You resisted Natural Request (Normal)!!]
Unfamiliar text appeared, but of course Jaeseok had no intention of refusing. What kind of man would turn down a big-breasted woman offering him fellatio?
That wasn't all.
-Sex! Ah, I'm dying for sex!!
-Shit, that bitch's eyes are looking at me like—
-If I could stick my dick between those tits, I'd have no regrets.
-Ugh, I'm short on cash. Maybe I'll buy myself a little treat and get my strength back.
-Those fucking bitches only care about money. Is it really that disgusting to do it just once?
The moment he found himself in a sexual situation, someone's voice began to run wild in his ears. Normally, Jaeseok would have done whatever he could to summon his will and resist it, but—
At this very moment,
the whispers became desire.
"...Do it."
"Okay~!"
[You yielded the initiative!]
[The prostitute's turn.]
"Wow, it's really big. It's hard even to fit it in my mouth..."
Smiling sweetly, the prostitute stuck out her tongue and spat a long string of saliva onto it.
Slurp!
Then she started licking.
"Gasp!"
It had been so long. Years, by his count, since he'd felt pleasure like this. Jaeseok's spine straightened, lightning flashed in his head, and it was hard to control his expression.
And it wasn't just because he was sensitive.
-Ah, sex!!!
-You fucking bitch, giving me that look—
-That damn bitch. She's so easy for handsome guys, but with me she—
-You only date me because of my body! Why the hell would you say something like that?
-Ah, today was exhausting again. I'm going home to jerk off.
The moment he found himself in a sexual situation, the countless voices and desires he'd suppressed in his mind began to run wild!
Right now, in this very moment,
the pleasure Jaeseok felt was ten times greater than normal. No—dozens of times greater!
"Slurp! Slurp! Smack! Smack!"
Her soft tongue came out and licked the tip of his urethra, then she opened her mouth, swallowed the front of his glans, and sucked hard.
A smooth tongue and a practiced suction unlike anything he'd ever experienced.
Jaeseok couldn't hold out.
In barely ten seconds, his pelvis began to thrum—
Gush! Gush! Gush!
"Ugh...!?"
Semen poured into the mouth holding his penis. Astonishingly, she gleefully swallowed every drop.
And once she'd swallowed it all—
[Sex Battle has ended!]
[Victory. Prostitute.]
"What?"
Jaeseok's eyes widened at the unbelievable text, and the prostitute smiled.
"That's it! Please leave!"
"What? No, wait a second. I've only just started."
"Oh my. Our rule is that once you ejaculate, it's over. Didn't you know?"
"Th-That's..."
"Hehe. I was surprised because you're so big, but you finished so easily. What a quick shot~♡"
Swoosh!
With her mocking words, the prostitute vanished like smoke.
"...Over? It's over? I didn't even get to penetrate her? And on top of that—"
Completely naked, Jaeseok let out a scream.
"I didn't even get to touch her tits!!!"
