Tuesday evening draped the apartment in muted twilight, the kind that softened edges and made ordinary spaces feel suspended between day and night. Emma stood in the bedroom doorway, adjusting the final button on her blouse. The silk was a deep emerald green, tailored close enough to trace the swell of her breasts without revealing too much—yet the fabric pulled taut across her chest with each breath, hinting at the warmth beneath. Her skirt, a charcoal pencil cut that ended just above the knee, hugged the firm curve of her ass and the long lines of her thighs. She had chosen the outfit with deliberate care after lunch, telling herself it was professional. The mirror disagreed, reflecting a woman who looked ready for more than paperwork.

“I have to head over to Marcus’s place downtown,” she called toward the living room, voice light but edged with something brisk. “Urgent tweaks on the new campaign. Shouldn’t be too late.” She slipped her feet into sleek black heels, the click sharp against the floorboards.

Alex looked up from the couch, laptop balanced on his knee, cursor blinking on an unfinished line of code. His throat tightened. The lie—if it even was one—sat between them like smoke. He managed a nod, the supportive husband mask sliding into place. “Drive safe. Text when you’re heading back.”

She crossed to him, leaned down, and pressed a quick kiss to his forehead, her hair brushing his cheek. The faint trace of her vanilla-amber perfume lingered as she straightened. Alex’s gaze followed her to the door, then to the window as she stepped into the hallway. From there he watched her cross the parking lot below, hips swaying with each stride, the streetlights catching the sheen of her skirt. His cock stirred, half-hard already, a familiar ache twisting with dread. She’s walking into his space now. Alone. And I’m sitting here pretending it’s just work.

Emma drove through the thickening evening traffic, city lights beginning to spark against the darkening sky. By the time she pulled into the underground garage of the sleek downtown high-rise, her pulse had settled into a low, steady thrum. The elevator rose smoothly to the penthouse floor. When the doors opened, the corridor smelled of polished stone and faint citrus from a hidden diffuser.

Marcus’s apartment waited at the end of the short hall. She knocked once. The door swung open almost immediately.

The space unfolded before her like a private gallery: floor-to-ceiling glass walls framing the glittering sprawl of the city below, skyscrapers reduced to jeweled pins against the night. Matte black leather sofas faced a low obsidian coffee table veined with subtle silver. Recessed lighting cast warm pools across concrete floors and minimalist art pieces that looked expensive enough to remain unnamed. The air carried a trace of sandalwood and clean linen. Marcus stood in the entryway, filling it without effort—six-four of solid muscle wrapped in a fitted black button-down, sleeves rolled to the elbows, exposing forearms corded with quiet strength. His dark skin glowed under the low lights, the top button of his shirt undone to reveal the strong column of his throat.

“Emma,” he said, voice deep and unhurried. “Come in. The ‘paperwork’ can wait.”

The excuse dissolved the moment the door clicked shut behind her. He didn’t bother with small talk. One large hand caught her waist, drawing her forward until their bodies met. The kiss started deep and possessive, his mouth claiming hers with a slow heat that made her knees soften. She tasted the faint edge of bourbon on his tongue as it slid against hers. His free hand roamed, unbuttoning her blouse with practiced ease, palms sliding inside to cup the full weight of her breasts. Thumbs brushed across her nipples until they tightened into aching peaks. She gasped into his mouth, the sound raw and open, nothing like the polite sighs she gave at home.

He guided her backward to the wide leather couch, lowering her onto the cushions without breaking contact. Fabric whispered as her blouse fell open completely. Marcus bent his head, lips closing around one nipple, sucking hard enough to draw a sharp moan from her throat. His teeth grazed the sensitive bud, tongue swirling to soothe the sting. She arched, fingers threading through his short hair, the city lights twinkling beyond the glass like silent witnesses.
