Min-jae gripped the phone, his knuckles white, as Dad's voice echoed through the speaker. "Min-jae? You sound off. Is everything alright at home?"
Ji-eun stepped back, her hand lingering on his shoulder for one last squeeze before she sauntered to the sink, hips swaying like she knew he was watching. She turned on the faucet, the water rushing loud, but her eyes stayed on him—dark, promising more. Her tank top clung to her curves, nipples still hard peaks, a reminder of how close they'd been. His cock throbbed under the table, aching from her touch.
"Yeah, Dad. Just... tired from exams." Min-jae forced the words out, his voice tight. Guilt surged again—lying to the man who'd brought Ji-eun into their lives, the one who thought she was the perfect replacement for Mom. But how could he explain this? The way her foot had pressed between his legs, her fingers stroking his bulge like it was hers to claim.
Dad chuckled, the sound tinny over the line. "I get it. Work's killing me here too. How's your mother? Tell her I miss her kimchi jjigae."
Min-jae's eyes flicked to Ji-eun. She was drying her hands, slowly, deliberately, her back to him now. That round ass in those shorts—firm, inviting. He imagined grabbing it, pulling her close. "She's... fine. Cooking soup tonight, actually."
"Good. Take care of her for me, son. And Yumi—make sure she doesn't stay out too late. Love you all. Talk soon."
The call ended with a click. Silence fell, broken only by the rain's relentless drum. Min-jae set the phone down, his hand shaking. The apartment felt smaller, charged, like the air before a storm breaks.
Ji-eun turned, leaning against the counter, arms crossed under her tits, pushing them up. "That was close, wasn't it?" Her voice was a purr, low and teasing. "What would Daddy say if he knew his son was hard for Mommy?"
He stood, chair scraping back. The guilt twisted, but lust won. "Ji-eun... Eomma... we can't."
She pushed off the counter, closing the distance. Her body heat hit him first, then her scent—jasmine and desire. "Can't what? Touch? Want?" Her fingers traced his chest, nails scraping lightly through his shirt. "You've wanted this for years. I see it in your eyes when you watch me. When I bend over to pick something up. When I hug you too tight."
Min-jae's breath came short. He grabbed her wrist, but didn't pull away. Instead, he held it there, feeling her pulse race. "It's wrong. You're my—"
"Mommy?" She finished, her free hand sliding down his stomach, fingers hooking into his belt. "Say it. Say you want Mommy."
The word broke him. "I want you, Mommy."
She smiled, triumphant, and pulled him close. Their bodies pressed together—her soft tits against his chest, her hips grinding lightly into his hardness. Min-jae's hands found her waist, slim and flaring to those wide hips. He squeezed, pulling a soft moan from her lips.
Their mouths crashed together. The kiss was hungry, desperate. Her lips parted, tongue seeking his, tasting of soup and sin. She nipped his bottom lip, hard enough to sting, then soothed it with a lick. Min-jae groaned into her mouth, his hands roaming—up her back, down to her ass, grabbing a handful of that round flesh.
Ji-eun broke the kiss, breath ragged. "Good boy. Mommy likes when you take what you want." She dropped to her knees, right there in the dining room, her face level with his zipper. Her fingers worked it open, slow, teasing. "Let me see how big my son's grown."
His cock sprang free, hard and throbbing, the tip glistening with precum. Ji-eun's eyes widened, then darkened with lust. "So thick. So ready for Mommy." She leaned in, breath hot on his skin, but didn't touch yet. Just hovered, her tongue darting out to lick her lips.
Min-jae tangled his fingers in her hair, guilt fading under the need. "Please, Eomma..."
She looked up, innocent and wicked all at once. "Please what, son?"
"Suck it. Suck Mommy's cock—no, my cock."
She laughed softly, then took him in her hand, stroking slowly. "Mommy's going to make you feel so good." Her lips brushed the head, a light kiss, then her tongue swirled around the tip, tasting the precum. "Mmm. Salty. Just like I imagined."
The sensation was electric. Min-jae's hips bucked involuntarily, pushing deeper into her mouth. She took him in, lips stretching around his thickness, sucking gently at first, then harder. Her head bobbed, hand twisting at the base, the other cupping his balls, rolling them lightly.
"Fuck, Mommy... your mouth..." He groaned, head falling back. The rain outside seemed distant, the world narrowing to her warm wet suction, the way her cheeks hollowed, her eyes locked on his.
She pulled off with a pop, strings of saliva connecting her lips to his cock. "You like Mommy's mouth on your big cock, son? Tell me how it feels."
"Amazing. Don't stop." He pushed her head back down, dominant now, thrusting shallowly. She gagged slightly, but moaned around him, the vibration sending shocks up his spine.
The apartment phone rang suddenly, shrill in the quiet. Min-jae froze, cock still in her mouth. Ji-eun didn't stop, sucking harder, her eyes twinkling with mischief.
It rang again. Yumi's ringtone.
Min-jae reached for it, but Ji-eun grabbed his hand, shaking her head with him still inside her. "Ignore it," she mumbled around his length.
But the ringing persisted. Yumi was calling from her friend's place. What if something was wrong?
He answered, voice hoarse. "Yumi? What's up?"
Ji-eun's tongue swirled, and he bit back a groan.
Yumi's voice came through. "Oppa? You sound weird. Is everything okay? I think I forgot my keys—can you leave the door unlocked? I'm coming home early."
Min-jae's eyes widened. Ji-eun pulled off, smiling wickedly, but her hand kept stroking. "Tell her yes, son. Mommy's not finished."
The door was unlocked. Yumi could walk in any minute.

How will they hide when the key turns in the lock?
