Betrayed By Him: Claimed By The Boss

The private elevator of the Upper East Side penthouse hummed quietly.

Katia stood in the center of the mahogany-paneled box. Her shoulders ached with a dull, heavy throb from the fourteen-hour flight from London.

She rolled her neck, feeling the tight muscles pull at the base of her skull.

The brass doors slid open with a soft chime.

She gripped the handle of her Rimowa suitcase and pushed it forward onto the familiar marble floor of the foyer. The apartment was completely silent.

She kicked off her black heels, her bare feet hitting the cold stone.

As she reached for the console table to drop her keys, her gaze snagged on the floor.

A pair of red Christian Louboutin stilettos sat carelessly near the edge of the Persian rug.

Katia's hand froze mid-air. The metal keys bit into her palm.

She stared at the red soles. She knew those shoes. She had complimented them last Tuesday in the boardroom.

They belonged to Sienna, Caleb's twenty-two-year-old executive assistant.

Katia's thumb pressed hard into the knuckle of her index finger, a nervous habit she couldn't break. The skin turned white under the pressure.

A sound drifted down the long hallway.

It was a high-pitched, breathy giggle. A woman's voice.

Then, a low, guttural groan followed. A man's groan. Caleb's groan.

Katia's lungs stopped working.

The air in the foyer suddenly felt too thick, too heavy to inhale. A cold sweat broke out across the back of her neck, chilling her skin.

Her stomach cramped violently, a sharp, twisting physical pain that made her want to double over.

The blood drained from her fingertips, leaving them completely numb.

The leather straps of her Hermes Birkin bag slipped from her grip.

The heavy bag hit the thick rug with a dull thud.

The sound was entirely swallowed by another, louder moan echoing from the master bedroom.

She didn't think. Her body moved on pure, mechanical autopilot.

Her bare feet stepped silently against the cold hardwood floor of the hallway. Each step felt like dragging her legs through wet cement.

The sounds grew louder. Wet skin slapping against skin. Heavy, rhythmic breathing.

She stopped outside the heavy mahogany door of the master bedroom.

It was cracked open. A sliver of bright afternoon sunlight spilled into the dark hallway, illuminating the dust motes in the air.

She didn't hesitate. She didn't tremble.

She raised her right hand and pushed the door wide open.

The hinges didn't make a sound. The afternoon sun poured through the floor-to-ceiling windows, blindingly bright against the king-sized bed.

Caleb was on top of Sienna.

Their bodies were tangled in the white Egyptian cotton sheets Katia had picked out three months ago.

Sienna's eyes fluttered open. She saw Katia standing in the doorway.

A piercing, terrified scream ripped from Sienna's throat.

She scrambled backward against the mattress, frantically pulling the white duvet up to her chin to cover her bare breasts.

Caleb jerked hard. He whipped his head around, his eyes wide
