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.

    One year later…"Can’t believe we came this far. Look at us," Kai said, grinning bright as he took a slow sip of his white wine.He looked around the sunny morning kitchen of their high-rise New York apartment. The city skyline stretched out through the floor-to-ceiling windows, bathed in warm morning light."I’m glad we gave love a chance," Damien replied, his dark eyes glowing with warmth as he clinked his glass gently against Kai’s own.Kai set his glass down on the marble counter and checked his watch. "Oops! Time is up. I need to go get the new case on the system. Damien, this one is so touching. The boy is fifteen years old. His boss trafficked him and sold him for prostitution. For five years, he has been working for this cruel boss and gets nothing for salary."Damien leaned against the island, shaking his head. "No way! That is too gruesome.""Yes way, love.

    The heavy armored door slammed shut behind them, cutting off the cold night air and the distant wail of sirens. Damien stood in the center of the plush cabin, his chest heaving under the dark hoodie. He stared at his father, his eyes wide with a mixture of disbelief, shock, and sudden, raw emotion. Magnus Voss slowly rose from the leather bench. The sharp, untouchable billionaire who had controlled boardroom tables for decades looked smaller now. His tailored suit was rumpled, the sharp lines of his face softened by deep exhaustion. For a long, heavy moment, neither of them moved. "Damien," Magnus said, his voice breaking on the single word. Damien took two fast steps forward and threw his arms around his father's shoulders. For the first time since the trial, father and son embraced, holding onto each other with a fierce, desperate strength. Damien buried his face into his father's shoulder, his hands gripping the back of Magnus's suit jacket. Magnus's composed façade finally

Loud screaming, the harsh sound of metal banging against metal bars, and footsteps filled the hallway. Sirens blared instantly, flashing blood-red emergency lights across the dark walls."What is that?!" Kai gasped, pulling his knees up to his chest as he sat on the thin straw mat.The main officer, who had been standing by the door preparing them for the morning public execution, snapped his head toward the iron gates. His radio burst to life with static and panicked shouting."All units to Block B! The inmates broke the security lock! I repeat, they are overrunning the guards!""Stay right here!" the officer shouted over the noise, turning back toward Kai and Damien. "Don't move an inch! We will finish taking you out to the square once we crush this riot!"He

    "Damien Voss and Kai Lennox, stand for your sentencing!" the head judge bellowed, his loud voice booming across the packed courtroom.The air inside the room turned to ice. Damien tightened his grip on Kai’s trembling, cuffed fingers underneath the edge of the wooden table. He squeezed tight, sending a clear signal that they were in this together until the very end.The judge adjusted his heavy glasses, looking down at them with cold, stern eyes. "For violating the sacred morals of this nation, and for refusing to show any remorse for your forbidden relationship, this court finds you both fully guilty. The sentence is "public execution by firing squad at dawn."A loud, collective gasp shattered the courtroom.Elena screamed from the front row of the gallery, a piercing, heart-breaking sound that echoed off the stone walls.

    The heavy iron door slammed shut with a deafening boom, locking Kai inside a cramped, damp cell.Kai pulled his knees tightly against his chest as he sat on the cold stone floor, trembling from head to toe. The air in the prison basement smelled like rust and old sweat. Across the dark room, two large, terrifying inmates sat on a concrete ledge, staring at him like hungry wolves."What do we have here?" one inmate growled, his voice deep and raspy. "A delicate little prince."Kai pressed his back flat against the rough stone wall, hiding his face in his hands as tears dripped onto his knees. He didn't say a single word. His mind was spinning with fear, constantly worrying about Damien. Where were they keeping him? Was he okay?Several corridors away, Damien paced back and forth across his own small holding cell. The steel cuffs were off his wrists, but his skin was raw where the metal had rubbed. He stared up at the tiny barred window near the high ceiling, his mind racing wildly.The

    Kai’s voice shattered the silence of the dark house as he screamed at the top of his lungs.He lunged across the kitchen floor, his hands wrapping tightly around his mother’s wrists just as the sharp, silver kitchen knife was inches from her chest."Mom, no! Stop! Drop it!" Kai shrieked, tears instantly blinding his vision as he wrestled the heavy blade out of Elena’s trembling fingers.The metal knife clattered onto the cold tile floor, sliding under the counter.Elena collapsed right into Kai's arms, her entire body shaking with violent, uncontrollable sobs. She gripped the fabric of his shirt so hard her knuckles turned white, letting out a loud, gut-wrenching wail that echoed off the empty kitchen walls."Mom, please look at me!" Kai cried out, pulling her close and holding her head against his chest. "Please, stop crying! I'm here! I'm right here!""How could you, Kai?!" Elena screamed through her heavy tears, beating her fists weakly against his chest. "How could you do this to
