Min-jae's pulse thundered in his ears as the apartment buzzer rang again—sharp, insistent, slicing through the heavy silence. Ji-eun froze mid-breath, her lace panties the only thing covering her, breasts still bare and flushed from the interrupted moment. Min-jae's cock strained painfully in his pants, the taste of her mouth still lingering on his tongue.
The buzzer rang a third time.
Ji-eun cursed softly under her breath, pulling the sheet up to cover herself. "Stay quiet," she whispered, eyes flicking to the door. "It's probably the security guard. Or a neighbor complaining about the noise."
Min-jae stayed rooted to the spot, heart slamming. The guilt was back in full force—Dad's voice still echoed in his head from the earlier call. *Take care of your mother and sister.* And here he was, in his stepmother's bedroom, cock hard, ready to fuck the woman who'd raised him.
Ji-eun slipped out of bed, pulling on a silk robe that barely tied around her curves. The fabric clung to her damp skin, nipples pressing through like they were begging for attention. She padded to the door, glancing back at Min-jae with a look that said *don't move*.
She cracked the door open. "Yes?"
A muffled voice from the hallway—young, male, apologetic. "Mrs. Kim? Sorry to bother you so late. There's a delivery for you. The driver said it's urgent."
Ji-eun sighed, voice calm and motherly again. "Can you leave it outside? I'm not dressed."
The guard hesitated. "It's from Mr. Kim. He said it's important. Flowers and a letter."
Min-jae's stomach dropped. Dad. Sending gifts from Singapore. Guilt twisted like a knife.
Ji-eun smiled politely. "Thank you. I'll get it in a minute."
She closed the door, turned, and leaned against it. The robe had loosened, one breast almost spilling out. She looked at Min-jae, eyes dark with frustration and hunger. "Your father has terrible timing."
Min-jae exhaled, running a hand through his hair. "We almost got caught. Twice in one night."
Ji-eun walked back to him, hips swaying, robe slipping further. "That's what makes it exciting, son." She stopped in front of him, fingers trailing down his chest. "The risk. The danger. Knowing we could lose everything... but still wanting it so bad."
Her hand dipped lower, palming his cock through his pants again. He groaned, hips jerking into her touch. "Mommy... we can't. Not now."
She squeezed. "Why not? Yumi's asleep. The guard's gone. Your father's on the other side of the world." She sank to her knees again, eyes locked on his. "Let Mommy finish what she started."
Before he could protest, she unzipped him. His cock sprang free, thick and leaking. Ji-eun licked her lips. "Look at you. So hard for Mommy." She wrapped her hand around the base, stroking slow. "You want to fuck my mouth again, don't you?"
"Yes," he hissed, guilt burning but lust winning. "Please."
She smiled, wicked. "Good boy." Her tongue flicked the tip, tasting the precum. Then she took him in—slow at first, lips stretching around his girth, tongue swirling. She moaned around him, the vibration shooting straight to his balls.
Min-jae's hands fisted in her hair. "Fuck, Mommy... your mouth feels so good."
She sucked harder, cheeks hollowing, head bobbing. Saliva dripped down her chin, onto her tits. She pulled off with a wet pop, stroking him fast. "You like watching Mommy suck your cock? Like seeing your stepmom on her knees for you?"
"Yes," he groaned. "Don't stop."
She took him deep, throat relaxing, nose pressing against his stomach. He thrust shallowly, fucking her mouth. She gagged softly but kept going, eyes watering, mascara smudging. Her hand slipped between her legs, rubbing her pussy through the lace.
"Touch yourself for me," he ordered, voice rough. Dominant now. "Show me how wet Mommy is."
Ji-eun moaned around his cock, pushing the panties aside. Her fingers slid into her shaved pussy, wet sounds filling the room. She fucked herself in time with her mouth on him.
Min-jae's balls tightened. "I'm close, Mommy."
She pulled off, stroking fast. "Cum in my mouth, son. Feed Mommy your cum."
He exploded—thick ropes shooting across her tongue, lips, chin. She swallowed what she could, moaning like it was the best thing she'd ever tasted. The rest dripped onto her tits, glistening in the low light.
She licked her lips, eyes gleaming. "Good boy. Such a big load for Mommy."
Min-jae panted, legs shaking. But before he could speak, the bedroom door creaked open.
Yumi stood there, eyes wide, phone in hand. She'd clearly come to check on the noise.
She stared at Ji-eun—kneeling, cum dripping from her chin, robe open, tits bare. Then at Min-jae—cock still half-hard, pants around his thighs.
Yumi's mouth fell open.
Ji-eun didn't panic. She stood slowly, wiping her chin with the back of her hand. "Yumi, sweetie... come in. Close the door."
Yumi didn't move. Her eyes flicked between them, cheeks flushing. "What... what is this?"
Ji-eun smiled, soft but dangerous. "Family secrets. Want to learn?"
Yumi's breath hitched. She stepped inside, door clicking shut behind her.
To be continued...
Will Yumi run? Or will she stay... and join them?
