"Checkmate." Tae tapped the chess piece with a painted fingernail, grinning across the board. Her silk robe slipped off one shoulder, revealing smooth skin.

Jeongguk groaned, rubbing his temples. "How do you keep winning? I studied chess theory for weeks."

"Natural talent, darling." She stretched lazily, the robe parting to show a flash of lace panties. Her husband's eyes lingered. "Besides," Tae purred, "you're distracted." She stood, letting the robe pool at her feet. Underneath, she wore only a sheer black negligee.

Jeongguk pulled her onto his lap. "Can't help it when my wife dresses like breakfast." He traced the curve of her hip. The morning sun caught her pink lips as she laughed. Their penthouse overlooked the city’s skyline, all steel and glitter.

"Breakfast?" Tae nipped his earlobe. "I planned to wear less than this to dinner tonight." She felt his grip tighten. "That little red dress. The one with the cutouts."

"Christ." Jeongguk's hand slid up her thigh. "You’ll give Jungkook a stroke."

Tae scoffed, twisting to straddle him properly. "Your brother stares anyway." Her negligee rode up, bare skin pressing against his slacks. "Let him choke."

Jeongguk kissed her collarbone. "Jealous?"

"Of what?" She arched into his touch. "I have the handsome twin. The nice one." Her fingers threaded through his hair. "The one who lets me buy these ridiculous outfits."

He chuckled against her throat. "You’d wear them regardless."

"True." She rocked her hips, feeling him harden beneath her. "But you love it." They kissed deeply, Tae grinding down as Jeongguk palmed her ass through the flimsy fabric.

Later, tangled in silk sheets, Tae traced scars on Jeongguk’s shoulder. "Meeting your brother for lunch?"

"Mm. Business." He kissed her temple. "Don’t burn down the apartment."

She slid a leg over his waist. "Only if you come home early." Her bare breasts brushed his chest. Jeongguk groaned, rolling her beneath him again.

Downstairs, the intercom buzzed. Tae grabbed Jeongguk’s discarded shirt, barely buttoning it. Jungkook’s voice crackled through. "Forgot my keys. Buzz me up?"

She pressed the entry button, shirt gaping open. The elevator pinged moments later. Jungkook froze in the doorway, eyes raking her exposed cleavage. "Fuck, Tae."

Jeongguk emerged, towel low on his hips. "Eyes up, brother."

Tae just smiled, stretching like a cat.

Jeongguk sighed, stepping forward to block Jungkook’s view. "Keys." He held out a hand, voice tight. Jungkook fumbled in his pocket, gaze still darting past Jeongguk’s shoulder. Tae leaned against the doorframe, letting Jeongguk’s shirt slip farther open.

"Here." Jungkook tossed the keys, eyes locked on Tae’s nipple peeking through the thin fabric. "Didn’t mean to interrupt... whatever." He smirked. "Though it looks fun."

Jeongguk caught the keys, knuckles white. "Lunch meeting. One hour. Don’t be late." He shut the door harder than necessary, the lock clicking loud in the sudden silence. Tae pouted, sliding her hands up his bare chest.

"Why so tense?" she murmured, pressing closer. "He’s harmless."

"Harmless?" Jeongguk gripped her hips, steering her away from the door. "He undresses you with his eyes every damn time." His thumb brushed the swell of her breast where the shirt gaped. Tae shivered.

"Jealous?" she teased, nipping his jaw. "Good. Means you care."

He groaned, pulling her flush against him. "I’m late." But his hands stayed on her ass, kneading through the shirt. Tae rocked against the towel still clinging low on his hips.

"One minute," she breathed, fingers tugging the damp terrycloth. Jeongguk’s breath hitched as it fell. Her hand wrapped around him, stroking slow. "Just one."

He cursed, pinning her against the wall. "You’re impossible." His mouth crashed onto hers, hungry. She moaned, arching into him as he lifted her leg around his waist. Fingers tangled in her hair, tugging her head back to expose her throat. He bit down—not gentle—and she gasped, nails digging into his shoulders.

The elevator pinged faintly from the hall. Jeongguk froze, forehead pressed to hers. "Fuck." He pulled back, breathing ragged. "Later." He swiped his towel, stalking toward the bedroom.

Tae watched him go, skin humming. She grinned, leaving the shirt unbuttoned as she padded to the kitchen. Pouring coffee, she heard Jeongguk dressing—zippers, the rustle of fabric. He emerged in a crisp suit, adjusting his cufflinks. His eyes darkened at the sight of her leaning against the counter, shirt barely covering her thighs.

"Red dress tonight," Tae reminded him, sipping her coffee. "The one with no back?"

Jeongguk grabbed her wrist, pulling her in for a rough kiss that tasted like caffeine and want. "Don’t tease Jungkook," he growled against her lips.

She laughed, low and throaty. "Only you."
