Emma strode into her brother's sleek corner office, the city skyline glittering behind floor-to-ceiling windows. "Alex, you called me up here at midnight? This better not be another one of your power plays." Alex leaned back in his leather chair, smirking. "Power play? Or just the only way to get my brilliant sister alone without the board interrupting?" Their banter sparked instantly, sharp as ever. "Brilliant enough to know you're stalling," she shot back, perching on his desk and crossing her legs. "What's the real agenda, big brother?"
Tension thickened as Alex stood, closing the distance. "The agenda is you drive me crazy in those meetings, Emma. Always challenging me, always so damn confident." She laughed, witty and unyielding. "Confidence isn't a crime. But if you're horny enough to mix business with pleasure, prove it." Their eyes locked, seduction building in the charged air until she pulled him closer by his tie.
"Prove it?" Alex murmured, hands sliding to her waist. "You're the one dripping with anticipation." Emma's reply was a grin and a firm push against the desk. "Talk less, act more." Clothes shed in a rush, her strong hands exploring as she dropped to her knees. She took his hard cock into her mouth for a teasing blowjob, tongue swirling while he groaned, sweating already.
"Fuck, Emma, that mouth," he panted, but she pulled back with a wicked smile. "My turn to lead." She bent over the desk, ass presented boldly. Alex thrust into her wet pussy from behind, the rhythm intense and mutual, her moans mixing with his as she rocked back, controlling the pace.
They moved to the couch, bodies slick with sweat, her riding him hard while trading quips between gasps. "Still think you're in charge?" she teased, clenching around him. "Horny doesn't equal victory," he countered, gripping her hips. Pleasure built until they came together, her pussy pulsing as his cum filled her, both panting in release.
Emma straightened her clothes with a satisfied smirk, already plotting the next move. "Office hours are over, but this? This is just the beginning." The door clicked shut behind her, leaving Alex wondering how far their forbidden game would spiral in the chapters ahead.
