Dungeon Mutation
The dungeon had transformed completely—from a cave into an open grassland.
“……Hah, hah.”
“…I-I’m gonna die.”
“Uggghhh…”
Rough, ragged breathing from Choi Jae-hyuk and the rest of the party echoed behind me. Seven hours of marching with backpacks stuffed full of mana stones had brought them to this.
“I can’t move another step… I’m a healer, for god’s sake…”
The brown-haired bob-cut healer, Park Yu-jin, finally collapsed onto the ground. Tears welled in her eyes as her legs trembled violently.
“We don’t rest until we find a safe zone. Or would you rather meet a monster right here and die together?”
My cold voice made Park Yu-jin’s shoulders flinch.
“Hey, isn’t that a little harsh?”
The guy who looked like her boyfriend supported her and spoke up, while the other party members glared at me with open resentment.
“Dude, the kids are dropping like flies!”
Choi Jae-hyuk barked while still shouldering his heavy load, panting hard.
“Then survive on your own.”
“……”
My indifferent reply shut Choi Jae-hyuk’s mouth tight. He knew better than anyone that the moment he left my side he would become monster bait.
I’ve tormented them enough. Time to head for the safe zone.
For the past hour I had deliberately led them in circles around the same area, grinding them down. All the while I used the excuse of hunting monsters to scout the surroundings alone, and that was how I had found the cabin.
Fortunately, even after the dungeon mutation the safe zone had kept its form.
The real problem is how long it lasts.
Unlike normal dungeons, the duration of a safe zone inside a mutated one was unpredictable. Sometimes it held for days; other times it collapsed in a matter of hours.
We’ll go in and assess the situation first.
I set course for the cabin and pointed to the small hut wrapped in a blue barrier out on the grassland.
“Good. We rest at that cabin up ahead.”
At my words a faint spark of life returned to the eyes of the half-dead party members.
“Ah… a safe zone!”
“We’re saved…”
The moment they confirmed the protective barrier, Choi Jae-hyuk and the others simply toppled to the ground. The backpacks they had carried for seven hours tumbled free with dull thuds.
We settled inside the safe zone. Most of the party used their packs as pillows and closed their eyes. A few were already snoring.
I claimed the cabin’s single room for myself, spread a clean cloth over the dusty bed, sat down, and closed my eyes to think.
Are there no other parties in this dungeon?
Even if there were, the odds they had already been wiped out were high. The moment you entered, the entrance spawned at a random location, so the chance of running into another party in the same dungeon was low to begin with. With a mutation on top of that, it was even lower.
This isn’t the time to worry about other parties.
I checked my condition. Fortunately my stamina still had plenty of reserve, and because I had been continuously absorbing the dungeon’s mana, my dantian remained completely full.
“……Um, Seo-jun.”
A careful voice broke the silence. I opened my eyes to find the healer Park Yu-jin opening the door and stepping inside.
“You must be exhausted… Would you like me to cast a simple vitality spell for you?”
“Aren’t you tired?”
“I am, but… the most important person in our party is you, Seo-jun, so…”
Her soft hands settled on my shoulders. Then, as if massaging me, her fingers began to move in a far more intimate way, stroking the nape of my neck and the muscles of my chest.
A subtle energy different from ordinary mana rode her fingertips, sending a strange pleasure through my whole body.
“How does that feel?”
Her gaze was far too sticky to be pure goodwill.
So this is the thing I’ve only heard about.
I remembered the boasts that occasionally popped up on the community boards.
An unofficial custom for unexpected crises: offering sexual service to the strongest person present in exchange for survival.
I had no intention of refusing a free gift that had rolled right into my lap.
“Not bad.”
“I’m glad…”
“But your boyfriend is sleeping outside. Is it okay for you to be rubbing another man’s body this carefully?”
“Th-that’s… the situation being what it is… getting you back in shape comes first, Seo-jun…”
I pulled her onto my lap.
“If you really care about me, you should do something more certain than a massage. Don’t you think?”
My hand slipped under the thin skirt of her priestess robes. She flinched and trembled, yet she did not push my arm away. Instead she parted her legs slightly, accepting my touch.
“Haa, hngh… Seo-jun…”
“Keep quiet. Unless you want to wake your boyfriend outside.”
“Wait… I’ll do everything you tell me. But in return…”
“In return?”
Yu-jin bit her lip lightly and whispered into my ear, breathing against it.
“Just… protect me. So I can get out of here alive.”
“That’s easy enough.”
“But what about my boyfriend?”
“…I don’t care. I just want to live.”
I understood. In a sealed space where death was breathing down your neck, morality and ethics were nothing but luxuries.
“Ahng…!”
My fingers rubbed her pussy through the fabric. She was already soaked; her panties clung wetly to her flesh.
“Haang…♡ Seo-jun… your fingers feel so… hngh.”
I stripped off her underwear and stuffed it into her mouth.
She didn’t look like she would be able to hold back her moans, so I gagged her in advance.
“Mmph, mmmph!”
With the damp panties clenched between her teeth and her face flushed with shame, Yu-jin looked up at me.
I opened my zipper, pulled out my cock, roughly spread her thighs, and drove into her in one thrust.
Schlick!
“Hngh-uuuh…♡”
Yu-jin squeezed her eyes shut and shook. Inside she was tight and hot. The moment I entered, her walls clamped down.
Pretty decent pussy for a little snack.
I gripped her waist and began to move slowly while whispering into her ear.
“Your boyfriend’s that small, huh? Your pussy’s only half-trained.”
“Mmph! Mmmmph…!”
Of course she couldn’t answer. Only muffled moans leaked past the panty gag.
Schlick, schlick, schliick—!
“Hnnngh…! Nngh-uuuh…♡”
I used Park Yu-jin like a fleshlight for about ten minutes.
Her inner walls contracted hard as she plunged into orgasm. At the same time her hips shuddered and she squirted like a premature ejaculator.
“Mm. Nowhere near as durable as Hwa-rin or Seo Ran.”
Left unsatisfied, I kept hold of the unconscious Park Yu-jin’s waist and forced her to keep rocking.
Schlick! Schliick!
Even as her body went limp with fading consciousness, her pussy still clenched my cock tightly and refused to let go.
I grabbed a fistful of her hair, yanked her head back, and slammed in deeper. Yu-jin’s eyelids fluttered; faint moans escaped around the gag.
“Mmph… nngh…♡”
The safe zone was still holding after seven hours. That peace was soon shattered by a sharp shout.
“Park Yu-jin… how could you do this?!”
Park Yu-jin’s boyfriend confronted her with bloodshot eyes.
The bastard seemed unable to process the fact that his girlfriend had slept with me.
“What can you even do for me, oppa? If it weren’t for Seo-jun we’d all be dead already!”
Park Yu-jin brazenly admitted she had fucked me and drove a spike straight into her boyfriend’s chest.
The man trembled with betrayal as he stared at her, but she had already hardened her heart and coldly turned away from him.
“Yu-jin, he threatened you, right? Just say that!”
“Seong-jin oppa, why are you being so pathetic? If you don’t have the ability, at least shut your mouth.”
“Aaaargh! You filthy slut!”
I watched their little soap opera with leisurely amusement and stretched.
Judging by Park Yu-jin’s attitude, she’s trying to switch sides.
Now that things had gone this far, she seemed to be aiming for the girlfriend position. The fact that she was already drinking the kimchi soup when the man who might give her the rice cake hadn’t even thought about it was so funny I almost laughed out loud.
Still, that face is passable, and even if her pussy is a premature-ejaculation machine, she’s not bad as a lust outlet.
While I enjoyed my private moment of leisure, the fight looked ready to escalate.
I stood up, moved beside Park Yu-jin, and deliberately grabbed her full breasts hard, pulling her against me for everyone to see.
“Enough noise. Keep it down. Safe zone or not, if you make this much of a racket the monsters will come running.”
“You son of a bitch! How dare you take someone else’s woman…!”
Blind with rage over losing his girlfriend, the bastard drew the sword at his hip without thinking.
Before he could swing it I kicked him.
“Guh!”
With a scream he rolled across the floor. I looked down at the pathetic sight and laughed.
“That’s why you should’ve kept a better watch on your girlfriend’s pussy.”
He stayed on the ground, glaring up at me as if he wanted to kill me. His eyes were full of hatred and murderous intent.
Should I just kill him?
A guy with eyes like that would only try to put a knife in my back if I left him alive. But there were too many witnesses. Unless I planned to kill Choi Jae-hyuk and the entire party as well, I couldn’t openly commit murder.
So I found a substitute.
“Jae-hyuk, manage your party members properly. If anyone else points a sword at me one more time, I’ll kill you instead.”
At my icy warning Choi Jae-hyuk trembled like an aspen leaf, rushed over, and seized the man by the collar.
“You crazy bastard! You got a death wish?! Apologize right now!”
Choi Jae-hyuk’s kicks and curses rained down on him.
Watching the scene, I casually groped the ass of Park Yu-jin, who was still in my arms. Even while watching her boyfriend get beaten, she buried her face against my shoulder and made a soft nasal sound.
“Seo-jun, calm down…. Don’t let that idiot ruin your mood.”
“I’m not angry. Or maybe I am. This down here feels a little angry.”
“Ah… want me to take care of one load right now?”
“Here? With everyone watching?”
“I don’t care. As long as you’re happy… I’ll do anything.”
She glanced toward her boyfriend, then deliberately dropped to her knees right in front of me for all to see.
Whether people watched or not, she had decided to become my complete bitch.
And with practiced skill she pulled my cock out of my pants.
“Haup…! Schlooop… tsssuup.”
Park Yu-jin’s hot mouth wrapped tightly around my cock. The sensation of her tongue tip teasing the urethra as she earnestly sucked was electric.
But an even greater pleasure lay elsewhere. The fact that I was violating another man’s woman right in front of her boyfriend delivered an intoxicating rush of ecstasy.
I could get addicted to this.
