My Step-Brother’s Obsession

Kai’s hands trembled as he gripped the steering wheel, the city lights of Riyadh blurring past. His mother’s bruised face flashed in his mind again, and the debt collectors’ final warning still ringing in his ears. “Pay up or we come for her again.” The memory hit him like a fresh wound.

He had come home from university that afternoon, backpack slung over one shoulder, exhausted from lectures and the constant worry gnawing at him. The moment he stepped into their tiny apartment, chaos exploded.

Two burly men in dark clothes were already inside. One smashed a chair against the wall while the other pinned his mother, Elena, against the kitchen counter.

“Where’s the money, woman?” the larger man snarled, shaking her violently. “You think we’re running a charity? The interest alone is killing us!”

Elena’s voice cracked. “Please… I just need a little more time. My son is studying. We’ll pay…”

A sharp slap cut her off. Kai dropped his bag and rushed forward, but the second man shoved him hard against the wall.

“Stay back, boy, or you’re next,” he growled.

Kai watched helplessly as they tore through the apartment—drawers yanked open, furniture overturned, their few precious belongings scattered like trash. One man grabbed his mother by the hair and slammed her against the table.

“You borrowed for your husband’s hospital bills. Then for the boy’s school. Now you hide behind excuses?” he spat. “Pay today or we take it out of your skin.”

Tears streamed down Elena’s face as she looked at Kai. “Don’t… don’t hurt him. Please.”

The men laughed and left with a final threat: “One week. Or we come back for both of you.”

Since his father’s death five years ago, it had been just the two of them scraping by in Riyadh. Elena had borrowed from ruthless underground lenders to cover hospital bills and keep Kai in school, believing she could repay every cent. Instead, the debts multiplied through impossible interest rates, and the lenders grew increasingly violent. That violence was why Kai hated the rich, powerful families who crushed people like them without a second thought.

That same evening, desperate to clear his head, Kai had taken the old car for a drive. A glowing sign outside a discreet building caught his eye: “Exclusive Private Club – Dominus Performers Wanted. $1000 per week. Discretion guaranteed.”

He had no choice. The money would buy them time…

The underground club loomed ahead, a sleek black building with no sign, invitation-only. Kai swallowed hard and stepped out of his beat-up car, adjusting the simple black mask the manager had sent him.

“You’re new,” the burly bouncer grunted, scanning his fake ID. “Manager said you’ve got potential. Dominus role. One night. Impress them, you stay. Fuck up, you’re gone. Under strict rules: performers remain masked at all times, no real names are ever exchanged, and clients are forbidden from touching anyone without explicit consent. Clear?”

“Crystal,” Kai muttered, voice steady despite the knot in his gut.

Inside, the air was thick with leather, sweat, and expensive cologne. Low red lighting pulsed over stages where masked performers worked their clients. Moans and the sharp crack of whips cut through the music. Kai’s stomach twisted. He hated this world of rich men who bought pain and pleasure like it was nothing.

The manager, a sharp-eyed woman named Lena, grabbed his arm and pulled him backstage. “You’re on in twenty, kid. Private suite. High-roller client. He’s been impossible tonight, nothing’s worked. Make him come or you’re out. Here’s your kit.” She shoved a sleek bag at him—whips, cuffs, gloves.

Kai changed quickly into fitted black leather pants and a harness that left his chest bare. The mask covered the top half of his face. He looked dangerous. Unrecognizable and good.

“What’s the client like?” he asked.

Lena smirked. “Damien Voss. Billionaire heir. He is as cold as ice. He pays triple for results. Don’t disappoint.”

The name hit like a punch. Voss. Everyone in the city knew that name. The name “Voss” is like a synonym for power, control, and money. The kind of family Kai despised.

But it was too late to back out now.

They led him down a dimly lit corridor to the private suite. The door opened. Kai stepped in, whip coiled in his hand.

A man sat in a large leather chair, shirt open, powerful body tense with frustration. He had dark hair, a sharp jaw, and his eyes were like steel. Damien Voss. Even masked in shadow, his presence filled the room.

Three other performers had already failed, Kai could tell from the discarded toys and the client’s bored, irritated expression.

Damien’s gaze locked on him. “Another one? This better be worth my time.”

Kai didn’t flatter. He didn’t kneel. He let the silence stretch, then cracked the whip once, sharp, controlled, the sound of the whip slicing the air.

“On your knees,” Kai ordered, his voice low and commanding. He stepped closer, boots silent on the thick carpet. “Now.”

Surprise flickered across Damien’s face. For the first time that night, something shifted in those cold eyes. He slowly lowered himself.

Kai moved with precision he didn’t know he possessed. The whip sank in, controlled lashes across Damien’s back and thighs, never breaking skin but delivering exactly the sting the man craved. Damien’s breath hitched. His body responded.

“Fuck,” Damien growled, muscles tensing. “Harder.”

Kai obliged, alternating pain with commanding touches, his gloved hands firm. He pushed Damien against the padded bench, dominating every move. The billionaire’s usual control shattered. He was hard, aching with pleasure for the first time in months.

When Kai dropped to his knees and took his cock in his mouth, deep and relentless while his hand worked the whip lightly against sensitive skin, Damien broke.

“Shit, yes..” Damien’s hips bucked. His hand fisted in Kai’s hair as he came hard, groaning low and raw.

The release was intense. Damien slumped back, chest heaving, staring at the masked man like he’d seen a ghost.

“Come here,” Damien rasped, reaching for the mask. “I need to see your face.”

Kai’s heart slammed against his ribs. He pulled back fast, dodging the hand.

“No,” he snapped.

Damien’s eyes narrowed with sudden obsession. “I said come here. I’ll pay whatever you want. Stay. Take the mask off.”

Kai panicked. Kai recognized the danger in that gaze, it was the same unyielding power that destroyed people like his family. He bolted for the door, whip still in hand.

“Wait!” Damien’s voice thundered behind him. “I’ll find you, boy. You’re mine now.”

Kai didn’t stop. He ran through the back halls, heart pounding, and burst out into the cool night air. He ripped the mask off, gasping.

The man he had just dominated was Damien Voss and he still couldn’t believe what just happened. The man whose family represented everything he hated.

His phone buzzed. It was a message from his mother: “The debts… they’re gone. A man named Magnus Voss paid everything. In return, he proposed. I said yes. We’re saved, Kai. Come home.”

Kai stared at the screen, his blood turning to ice. The same powerful family.

Oh God! He had just whipped and sucked off his mother’s future stepson.
