The door to the cramped basement room creaked open without a knock, flooding the dim space with harsh hallway light. Kim Jae-hung didn't bother looking up from where he sat cross-legged on the thin mattress that served as his bed. His eyes were fixed on the translucent blue panel hovering in front of him, visible only to him.
Even without turning, he knew exactly who it was. The heavy scent of her floral perfume, mixed with something sweeter, drifted in first, followed by the steady click of high heels on the concrete stairs.
His aunt, Park Ji-yeon, stepped into the room like she owned it. In a way, she did. It was her house, after all.
She was dressed to kill, as always. A tight black crop top clung to her full breasts, the thin fabric stretched enough to show the outline of her lacy bra, her nipples faintly pressing against it.
The top ended just below her ribs, exposing a toned midriff and a glittering navel piercing that caught the light. Low-rise yoga pants hugged her wide hips and thick ass like a second skin, riding low enough to reveal the thin strings of a thong peeking above the waistband. Her long, wavy black hair fell over one shoulder, and her full lips were painted a glossy crimson.
Park Ji-yeon leaned against the doorframe, one hand on her hip, pushing her chest out slightly.
"Dinner's in the fridge if you want it, Jae-hung," she said, her voice low and husky, carrying that familiar mocking edge. "It's leftovers from yesterday, so microwave it. And don't forget to finish that hole in the backyard later. I want it deep enough for the pool by the end of the week."
Jae-hung barely nodded. "Yeah, sure." Even though she was dressed in a way that would tempt anyone on a normal day, his gaze stayed locked on the floating system window.
[First Target: Park Ji-yeon (Uncle's Wife)]
[Objective: Conquer her completely.]
[Reward: An SS-rank skill with no drawbacks.]
[Current Progress: 0%]
A slow, predatory grin spread across his face.
Park Ji-yeon raised a perfectly shaped eyebrow, clearly annoyed at being ignored. She turned with a huff, her ass jiggling as she climbed back up the stairs.
Only when the door clicked shut did Jae-hung release a slow breath.
Kim Jae-hung was a twenty-year-old F-rank Hunter—the absolute bottom in a world that had changed fifty years ago when gates began appearing, portals to monster-filled dungeons.
Some humans awakened with ranks from F to S, and later even SS and SSS. These people were known as Hunters. Because of them, the world's social and political order shifted. A hunter's power decided everything: wealth, status, respect, and even a nation's strength.
And Jae-hung? He was F-rank. The weakest of the weak. Unable to clear even the lowest dungeons alone, barely stronger than a normal human. In society, F-ranks were treated as less than civilians; just disposable trash.
Jae's parents had died in a gate break when he was young. His uncle—his mother's older brother took him in, but only out of obligation. In truth, Jae-hung was little more than free labor.
After years of odd jobs, licking Hunters' boots, and begging his S-rank best friend for money, he finally managed to move out.
Then, a week ago, his aunt had called him with a sweet voice. "Come stay with us for a bit, Jae-hung-ah. I have a job for you."
It sounded like an easy way to earn money and get free meals, and since his uncle wasn't around, he agreed.
That "job" turned out to be digging a massive hole in the backyard for a luxury swimming pool his S-rank uncle wanted.
Those were the kinds of jobs F-ranks got. They were stronger than normal humans, so people figured they could swing a shovel all day. In the end, they earned nothing but pocket change.
From six in the morning, he had been swinging that damn shovel under the blazing summer sun.
But that wasn't the point. Today, Jae-hung's life changed.
By pure chance, the blade of his shovel struck something hard. It wasn't a rock. It was something else entirely.
Digging deeper, he uncovered a corpse—perfectly preserved, as if it had been waiting for him. A skeletal figure in tattered robes, radiating an ancient, sinful aura. The moment his fingers brushed the bones, everything changed.
That was when the system window activated. At first, he thought he was hallucinating. When the system asked him to choose a path, he picked the path of taboo. Now, he was certain it was real.
"What the fuck."
A system meant to turn him into the ultimate degenerate. A system that could raise him from F-rank all the way to SSS-rank.
Jae-hung was deep in thought when his stomach growled loudly.
He looked down and sighed. "Fine. Food first. Then I'll think."
He stood, stretched his aching muscles, and headed upstairs toward the kitchen.
The sight waiting for him made his cock twitch instantly.
Park Ji-yeon was bent slightly over the kitchen island, her side to him, yoga pants stretched tight across her plump ass. One hand rested on the counter. The other—
She held a thick, ridged cucumber in her right hand, sliding it slowly between her legs. The waistband of her pants was pulled down just enough to expose the top of her creamy ass cheeks and the thin black thong disappearing between them. She rubbed the cold vegetable along her clothed pussy, hips rolling in small circles, soft gasps slipping from her glossy lips.
Her eyes were half-lidded, lost in pleasure. She clearly thought she was alone.
Jae-hung froze in the doorway. Every instinct told him to back away.
Then the system panel flickered again.
[Emergency Mission Unlocked!]
[Objective: Make your aunt cook a hot meal for you tonight.]
[Reward: Permanent stat increase to E-rank baseline + Unique Skill: Enchanting Gaze]
[Failure Penalty: None]
Jae's lips curled into a wicked grin.
This was it. The first step.
He stepped fully into the kitchen, letting his footsteps echo.
Ji-yeon's head snapped around. Her eyes widened as she saw him, the cucumber still pressed between her thighs. A deep red flush spread across her cheeks and down her neck, vanishing into her cleavage.
"J-Jae!" she stammered, yanking the vegetable away and pulling her pants up. "What are you—get out! This isn't—"
He didn't retreat. Instead, he leaned against the counter, eyes roaming over her body, lingering on her heaving chest and the dark, damp spot visible on her yoga pants.
Ji-yeon clutched the cucumber like a weapon, her face burning. "You saw nothing. You will tell no one. Especially not your uncle."
Jae-hung chuckled and stepped closer. "Why would I tell him, Aunt Ji-yeon?" he said softly, an innocent smile on his lips. "You weren't doing anything wrong. Besides, if a man leaves a woman as beautiful as you this unsatisfied, I doubt he'd care."
She blinked, still flustered. "W-what are you talking about?"
His smile softened, one hand rubbing the back of his neck. "I'm saying your secret is safe with me. But…" His gaze dropped meaningfully. "I'm really hungry. Who knows what I might remember by tomorrow morning."
Her eyes narrowed, embarrassment turning into suspicion. "Is that a threat?"
Jae-hung waved a hand. "No, nothing like that. But you don't mind cooking something for me, right?"
Ji-yeon stared at him for a long moment. "Fine," she said at last. "But if anyone hears about this, I will kill you."
Jae smirked. "Of course. No one will hear a thing."
Ding!
