She stood in the doorway of the shadowed penthouse, the city lights flickering far below like distant warnings she chose to ignore. Marcus waited in the center of the room, his silhouette sharp against the floor-to-ceiling windows, arms crossed, eyes fixed on her with the calm certainty of a man who already owned what he saw.
"Close the door," he said, his voice low and unyielding. "And obey me."
Sophia obeyed. The latch clicked like a final judgment, sealing her inside his world. Her pulse hammered at her throat as she stepped forward, the silk of her dress whispering against her thighs. He had chosen it for her earlier that day, a thin black slip that barely covered the lace beneath. No underwear. That had been his first command of the evening, delivered in a text that left her wet and restless at her desk.
Marcus circled her once, slow and deliberate, his fingers trailing the line of her spine without quite touching. "On your knees."
She sank down, the hardwood cool against her skin. Her breath came shallow as she looked up at him, waiting. The power in the room was his alone, thick and electric, pressing against her until every nerve hummed with anticipation. He unbuckled his belt with deliberate patience, the leather sliding free in one smooth pull. The sound alone made her thighs clench.
"Hands behind your back."
Sophia crossed her wrists at the base of her spine. He bound them with the belt, tight enough to remind her she was restrained but not so tight she couldn't feel the throb of her own heartbeat. Then he stepped closer, the hard line of his cock straining against his trousers inches from her mouth.
"Open."
She parted her lips. He fed himself to her slowly, the weight of him sliding over her tongue until he hit the back of her throat. She took him deeper, eyes watering, because that was what he wanted and her body had learned to crave the approval in his low groan. His hand fisted in her hair, guiding her rhythm, using her mouth with controlled hunger. Saliva slicked her chin. Her nipples tightened painfully against the silk.
"Good girl," he murmured. "You obey so beautifully."
The praise flooded her, hot and shameful and addictive. When he pulled free, she whimpered at the loss. He lifted her without effort, carrying her to the wide leather couch that faced the windows. He bent her over the arm, the city spread out beneath them like an audience she could never see.

Cool air kissed her bare ass as he raised the hem of the dress.
His palm cracked across one cheek, sharp and stinging. She gasped, hips jerking forward. Another slap followed, then another, until heat bloomed across her skin and her cunt dripped with need. Marcus slid two fingers through her folds, testing how ready she was, and chuckled darkly at the evidence.
"So wet for my commands," he said. "Tell me what you want."
"To obey you," she answered, voice trembling. "Please."
He freed himself fully and thrust inside her in one smooth stroke, stretching her open around his thickness. Sophia cried out, the fullness overwhelming. He set a punishing pace, one hand gripping her bound wrists, the other pressing between her shoulder blades to keep her pinned. Each snap of his hips drove her harder against the leather, the slap of skin echoing through the room.
He reached around and rubbed her clit in tight circles, never letting her forget who controlled every sensation. "You don't come until I say."
She nodded frantically, already trembling on the edge. He fucked her deeper, angling to hit the spot that made stars burst behind her eyes. Her thighs shook. Sweat slicked her back. Still he denied her, pulling out just as her walls began to flutter.
Marcus flipped her onto her back, spreading her legs wide. He entered her again, slower this time, watching every flicker of expression on her face. His thumb pressed against her clit with ruthless precision. "Look at me when you beg."
"Please," she whispered, meeting his dark gaze. "Let me come. I'll do anything."
"Anything," he echoed, voice rough. "Obey me completely."
He drove into her harder, faster, until the coil inside her snapped. Pleasure tore through her in violent waves, her cunt clenching around him as she screamed his name. Marcus followed seconds later, burying himself to the hilt and flooding her with heat, his growl of release vibrating against her throat.
In the aftermath he unbound her wrists, rubbing circulation back into her hands with surprising tenderness. He pulled her into his lap on the couch, her head against his chest, the steady beat of his heart grounding her. Outside, the city continued its indifferent glow, but here the only light that mattered was the one in his eyes when he looked down at her.
"Tomorrow," he said quietly, "you'll wear the marks I left. And every time you feel them, you'll remember who you belong to."
Sophia closed her eyes, a small, satisfied smile curving her lips. She already knew the answer. She would obey. She always would.
