Do Jin was buried to the hilt inside Kim Hye Jin's tight, dripping pussy when they both heard it.
The slow, heavy footsteps of her husband climbing the stairs.
Thud… Thud… Thud…
Hye Jin's eyes widened in pure panic. Her body tensed violently around his cock, squeezing him like a vice.
"Stop—!" she whispered desperately, her voice barely a breath. "He's coming up!"
Do Jin didn't pull out.
Instead, he leaned in closer, pressing his chest against her breasts, and whispered hotly against her ear:
"Then you'd better stay very, very quiet, Headmistress."
He gave one slow, deep thrust.
Hye Jin's mouth opened in a silent scream. Her nails dug painfully into his shoulders through his shirt as she fought to hold back any sound.
The footsteps were getting closer.
Thud… Thud…
Do Jin started moving — slow, controlled, but powerful strokes. Each thrust pushed his thick cock deep into her soaked heat, grinding against her most sensitive spot.
Hye Jin's legs trembled. She bit her lower lip so hard it almost bled.
Down the hallway, her husband's voice called out casually:
"Hye Jin? Are you in the bedroom? I made more coffee. Want some?"
Hye Jin's eyes rolled back for a second as Do Jin rolled his hips, fucking her with deep, deliberate movements while she tried to answer.
"I-I'm here…" she managed to say, her voice strained and higher than usual. "The repairman is… fixing the fan. Don't come in."
Do Jin smirked darkly and slammed into her harder, forcing a tiny, choked whimper out of her throat.
Her husband stopped right outside the door.
"Why is the door almost closed? Is everything okay?"
Do Jin didn't stop. He fucked her with steady, punishing rhythm — pulling almost all the way out before driving back in, making her body jolt against the wall with every thrust.
Hye Jin's hand flew to her mouth, covering it desperately as her eyes watered from the overwhelming pleasure and terror.
"Yes… everything is fine," she forced out, her voice shaking. "He's almost… ah… almost done."
Do Jin reached between them and rubbed her swollen clit with his thumb in fast circles while continuing to thrust.
Hye Jin's knees buckled. She would have fallen if Do Jin wasn't holding her up against the wall.
Her husband's voice came again, now sounding slightly suspicious:
"You sound strange. Are you sure you're okay?"
At that exact moment, Do Jin changed the angle and hit her G-spot perfectly.
Hye Jin's entire body convulsed. A powerful orgasm crashed through her without warning.
She came hard — her pussy clamping down around his cock like a fist, gushing wetly around him.
A broken, muffled moan escaped from behind her hand:
"Mmmph—!!"
Do Jin kept fucking her through it, drawing out her climax as long as possible while her husband stood right outside the door.
Hye Jin's legs shook violently. Tears of overwhelming pleasure and fear rolled down her cheeks. Her conservative bun had come loose, strands of hair sticking to her sweaty forehead.
Her husband paused for what felt like an eternity.
"…Alright. I'll be downstairs if you need anything."
The footsteps finally retreated back down the stairs.
The moment they heard the living room door close, Hye Jin let out a broken sob of relief and pleasure.
"You… crazy bastard…" she gasped, still trembling from her orgasm.
Do Jin didn't give her any time to recover.
He spun her around roughly, bent her over the edge of the bed, and slammed back into her from behind in one brutal thrust.
Hye Jin's face pressed into the mattress as she moaned loudly into the sheets.
Do Jin grabbed her hips and started pounding her mercilessly. The sound of skin slapping against skin filled the room — wet, obscene, and loud.
"Fuck… you're even tighter when you're scared," he growled, spanking her ass hard.
Hye Jin's muffled cries grew louder with every thrust.
"I can't… I can't take it…" she whimpered into the mattress, but her hips were pushing back against him, begging for more.
Do Jin reached forward and grabbed her hair, pulling her head back so he could whisper in her ear while fucking her senseless:
"You're the strict headmistress who terrifies everyone… yet here you are, bent over getting fucked by a repairman while your husband is downstairs."
Hye Jin's pussy clenched violently around him again.
Another orgasm was building fast.
Do Jin fucked her even harder, the bed creaking dangerously under them.
"Come again," he ordered. "Cum on my cock while your husband is right below us."
Hye Jin shattered.
Her second orgasm hit her like a storm. Her entire body convulsed as she buried her face into the mattress and screamed silently, her pussy gushing and spasming around Do Jin's cock.
The intense contractions pushed Do Jin over the edge.
With a low, guttural groan, he buried himself as deep as possible and came hard.
Thick, hot ropes of cum flooded deep inside her, filling her womb completely.
They stayed locked together for a long moment, both panting heavily.
Hye Jin's legs were shaking so badly she could barely stand.
Do Jin slowly pulled out, watching his cum drip down her thighs from her ruined pussy.
He leaned down and whispered in her ear:
"Next time, I want you to ride me while your husband watches TV in the next room."
Hye Jin turned her head weakly, her face flushed and ruined, glasses long gone.
"You're going to get us both killed…" she breathed, but there was a strange spark of dark excitement in her eyes.
The system's voice exploded with joy:
[Mission Success Under Extreme Risk!]
[SP Reward: 180 base + 92 bonus (near-discovery + multiple orgasms) = 272 SP]
[New Title Unlocked: Danger Fucker]
[Kim Hye Jin's Status: Broken & Addicted (Level 1)]
Do Jin helped her stand on shaky legs and handed her the glasses.
"Fix your clothes, Headmistress," he said with a smirk. "Wouldn't want your husband to see what a slut you become when no one's watching."
Hye Jin glared at him weakly, but she couldn't hide the satisfied glow on her face.
As Do Jin picked up his toolbox and headed toward the door, the system sent one final message:
[You barely escaped this time.]
[But the hunger in her eyes says she already wants more…]
[Next time, the risk will be even higher. Are you ready?]
Do Jin stepped out of the bedroom with a calm smile, leaving the strict headmistress leaning against the wall, legs still trembling, cum running down her thighs.
He had done it.
He had fucked the untouchable Headmistress Kim Hye Jin while her husband was literally downstairs.
And he was already craving the next dangerous gamble.
