Do Jin arrived at the large two-story villa in one of Gangnam's quieter, more exclusive neighborhoods just after 2 PM.
The house belonged to Kim Hye Jin — 45 years old, strict headmistress of Seoul's most prestigious private girls' school. Known for her iron discipline, conservative values, and zero tolerance for any nonsense.
The perfect target for a high-risk mission.
As he pressed the doorbell, the system's voice rang in his head with clear excitement:
[Mission: The Headmistress Trap – Activated]
[Special Condition: Her husband is currently home, reading newspapers in the living room.]
[Objective: Seduce and fuck Kim Hye Jin without getting caught.]
[Risk Level: ★★★★☆]
[Reward: 180–250 SP + High Risk Multiplier]
[Fail Condition: Getting discovered = Severe Punishment]
The door opened.
Kim Hye Jin stood before him.
She was taller than average, with a strict, elegant beauty. Her black hair was tied in a tight bun. She wore a white blouse buttoned all the way up, a long gray pencil skirt that reached below her knees, and thin-rimmed glasses. Her posture was perfect — like a woman who was always in control.
She looked Do Jin up and down with sharp, appraising eyes.
"You're the repairman?" she asked, her voice cold and authoritative.
"Yes, ma'am. Kang Do Jin. I was told there's an issue with the ceiling fan in the master bedroom."
Hye Jin glanced briefly toward the living room where her husband — a chubby man in his late 50s — was sitting comfortably, reading the newspaper and drinking coffee.
She lowered her voice slightly.
"Follow me. And be quiet. My husband is resting."
Do Jin nodded and stepped inside, carrying his toolbox.
The moment he entered the house, he felt the heavy atmosphere. This was not a home filled with warmth. It was orderly, controlled, and clearly sexually dead.
They climbed the stairs in silence.
When they reached the master bedroom, Hye Jin closed the door behind them, but not completely — leaving it slightly ajar.
"The fan makes a strange noise at night," she said formally. "Fix it quickly."
Do Jin set his toolbox down and looked at the ceiling fan. It was perfectly fine. He had checked the report — this was clearly a fake request.
He turned to her.
"Mrs. Kim… this fan doesn't have any problem."
Hye Jin's eyes narrowed behind her glasses.
"Then why are you here?" she asked, but her voice wasn't as steady as before.
Do Jin took one slow step closer to her.
"Because you called for me," he said quietly. "Just like Mrs. Lee and Attorney Park did."
Hye Jin's cheeks flushed slightly, but she quickly composed herself.
"I don't know what you're talking about. Fix the fan or leave."
Do Jin didn't move. Instead, he activated his Magnetic Pheromone skill consciously for the first time, letting his presence fill the room.
Hye Jin's breathing changed. She unconsciously took a small step back until her back touched the wall.
"Do you always keep your bedroom door open when a man is inside?" Do Jin asked softly, his eyes never leaving hers.
"My husband is downstairs," she whispered sharply. "If he hears anything—"
"Then we should be very, very quiet," Do Jin finished for her.
He stepped even closer until their bodies were almost touching. Hye Jin's chest rose and fell rapidly. Her conservative blouse suddenly felt too tight.
The system pinged:
[Arousal level: 64% and rising fast]
[Husband is still in the living room, 12 meters away]
[Every sound you make will be extremely risky]
[This is exactly the kind of gamble I love]
Do Jin reached out and slowly removed her glasses, folding them and placing them on the bedside table.
Hye Jin's eyes widened.
"What do you think you're doing?" she hissed, but she made no move to stop him.
Do Jin leaned in, his lips brushing against her ear.
"I'm doing what your body has been begging for years, Headmistress."
He kissed the side of her neck gently.
Hye Jin shivered violently. A soft, suppressed whimper escaped her lips.
She grabbed his shirt with both hands, as if she wanted to push him away… but instead, she pulled him closer.
"You're crazy…" she whispered. "If my husband comes up…"
"Then you'll have to stay very quiet while I fuck you," Do Jin replied, his voice dark and confident.
His hands moved to her blouse. One by one, he unbuttoned it, revealing a plain white bra covering her surprisingly full breasts.
Hye Jin's face burned with shame and arousal.
"I… I can't…" she whispered, even as her hips moved slightly toward him.
Do Jin slid his hand under her long skirt, slowly moving up her thigh until his fingers reached her panties.
They were already wet.
He smiled against her neck.
"Your mouth says no… but your pussy is honest."
Hye Jin bit her lip hard to stop herself from moaning.
Downstairs, the sound of her husband turning the newspaper page could be faintly heard.
Do Jin pushed two fingers under her panties and stroked her soaked folds.
Hye Jin's legs almost gave out. She gripped his shoulders tightly.
"Stop… ah… my husband…" she breathed, but her hips were already grinding against his hand.
Do Jin kissed her deeply, swallowing her soft moans as his fingers circled her swollen clit.
The danger made everything ten times more intense.
The system was loving it:
[SP earned so far: 63]
[Risk Multiplier: x2.8]
[Husband just stood up to get more coffee… He might come upstairs any minute]
Do Jin pulled his fingers out and brought them to Hye Jin's lips.
"Taste how wet you are for a repairman," he whispered.
Hye Jin, the strict headmistress who punished students for the smallest mistakes, obediently opened her mouth and sucked his fingers clean, her eyes glazed with lust.
Do Jin unzipped his pants and freed his hard cock.
He pressed the thick head against her dripping entrance, rubbing it up and down her slit.
Hye Jin looked at him with desperate eyes.
"Please…" she whispered so quietly he almost didn't hear it. "But… be quiet…"
Do Jin pushed forward slowly, stretching her tight pussy open.
Hye Jin's mouth opened in a silent scream as he sank deeper and deeper inside her.
At that exact moment, they both heard it.
The sound of her husband's footsteps starting to climb the stairs.
