The evening sun painted the Jeon mansion in gold as the family gathered in the vast living room. The chandeliers glowed, the marble floors sparkled, and the laughter of wealth and comfort filled the air.

Junhyun sat in his armchair, sipping whiskey, while Tae curled herself gracefully on the velvet sofa beside him. Her legs were crossed, her silk dress riding dangerously high on her thighs. Across from them sat Jungkook, pretending to focus on his phone but stealing glances at his stepmother every few seconds.

Junhyun cleared his throat, voice warm but firm.

“Kook-ah… you’re twenty now. A man. Isn’t it time you start dating girls seriously? You can’t stay locked up in that gym forever.”

Jungkook’s ears turned pink. “I-I’m not… I mean, I will… eventually.”

Tae gasped dramatically, covering her mouth with her dainty fingers. “Omo, our little Kook is shy around girls?”

Her husband chuckled. “That’s what I’m saying. He’s tall, handsome, and strong, but he freezes up the moment a woman looks at him. What a waste!”

Tae leaned toward Jungkook, her perfume flooding his senses. “Don’t worry, yeobo,” she said to her husband with a sly smile. “I’ll help him. I’ll teach him how to seduce a girl properly.”

Junhyun laughed, slapping his knee. “Good idea! Who better than you, darling? You had me wrapped around your finger the moment I met you.”

All three laughed together, but Jungkook’s laugh was thin, nervous. His eyes dropped to his lap, hiding the way his throat tightened at the thought.

Later that night, the mansion was quiet. Junhyun had gone to his study for late business calls. Jungkook was lounging on the sofa, half-watching the muted TV, when Tae glided into the room.

She was in another of her revealing silk nightgowns — pale lavender, thin straps, lace trimming that barely held her breasts in place. The slit along her thigh opened with every step.

She plopped down beside him, tucking her legs under her body, facing him with a playful smile.

“So, Kook-ah… shall we start your lesson?”

He swallowed. “L-Lesson?”

“Mmhm.” She leaned closer, her robe slipping from one shoulder. “On how to seduce a woman.”

He froze, eyes wide. “Y-You were serious?”

“Of course I was.” She giggled, twirling a lock of her hair. “You don’t want to be single forever, do you? Poor baby. Girls won’t know how to handle you unless you… handle them first.”

He coughed, shifting uncomfortably. “I… I don’t really know what to say to them.”

“Then listen carefully.” She tapped his knee, her nails grazing his skin. “Rule number one: don’t stare at your phone. Look at her. Hold her eyes. Make her feel like she’s the only girl in the world.”

She demonstrated, tilting her head and locking her gaze onto him. Her eyes were dark, mischievous, unblinking. Jungkook squirmed, his chest tightening.

“See? You’re already nervous,” she teased.

“I’m not—”

“Shh. Don’t deny it.” Her voice dropped low, sultry. “Rule number two: compliment her. But not just her face. Say something that makes her body feel… seen.”

He stammered, “Like… um… ‘you have… nice hair’?”

She burst out laughing, leaning forward until her breasts nearly brushed his arm. “Aigoo, you’re hopeless. Try again.”

Jungkook’s throat went dry. He whispered, barely audible, “Your… your lips are pretty.”

Tae smirked, licking her lips slowly. “Better. See? You made me blush.”

He groaned softly, pressing a fist against his knee.

“And finally…” She leaned so close now he could feel the warmth of her breath. “…don’t be afraid to touch. Lightly. Just enough to make her wonder what else you’ll do.”

She placed her hand over his, squeezing gently, her thumb stroking his skin. His entire body stiffened.

“T-Tae…” he breathed.

She tilted her head, innocent smile plastered on her sinful face. “What’s wrong, Kook-ah? This is just practice. So when you meet a real girl, you’ll know exactly what to do.”

Her hand slid off his, brushing down his thigh as she stood up. She stretched, her nightgown parting even wider. “Lesson one complete. You’re such a fast learner.”

And with a wink, she padded upstairs, leaving him hard, sweating, and trembling on the sofa.
