The Billionaire's Blood Debt: Ruined by My Enemy

Elowen's POV

The silk of my Vera Wang gown felt like a second skin, cool and expensive against my flushed flesh. I caught my reflection in one of the gold-trimmed mirrors of the Plaza Hotel's Grand Ballroom and smiled. For the first time in years, the St. Claire name meant something again. Tonight was my engagement gala, the night I was supposed to become Elowen Montgomery, the woman who saved her family's legacy by marrying into the most powerful old-money dynasty in New York.

"You look breathtaking, Elowen," Thatcher whispered, sliding his hand around my waist.

I leaned into him, inhaling the scent of his cologne. "It feels like a dream, Thatcher. Thank you for everything."

He squeezed my hip, his eyes darting toward the massive LED screens flanking the stage. "Everything for my future wife. Now, are you ready for the tribute video? I spent weeks putting it together."

"I'm ready," I said, my heart fluttering with a mix of excitement and nerves.

The lights dimmed. A hush fell over the four hundred guests-the elite of Manhattan, the people who had looked down on my father after the scandal and were now back to kiss our feet. The music started, a soft, romantic piano melody.

The screens flickered to life. But it wasn't our childhood photos that appeared.

It was a bedroom. My bedroom.

The room went deathly silent. At first, I thought it was a mistake-a technical glitch. But then the moans started, piped through the high-end sound system so clearly it felt like they were in the room with us.

On the screen, a woman's back was arched, her head thrown back in a state of pure, animalistic ecstasy. It was my younger sister, Bianca. And the man between her legs, his face buried in her chest as he groaned her name, wasn't some stranger.

It was Thatcher.

"Thatcher?" I whispered, the word tasting like ash in my mouth.

He went pale, his hand dropping from my waist as if I were made of lead. "Elowen, I... that's not..."

The video zoomed in. Bianca's hand reached out, grabbing the headboard-the custom-carved mahogany headboard I had picked out for our new home. She looked directly into the camera, a smirk of pure, poisonous triumph on her face.

"He loves me more, Elowen," she gasped on the recording. "He always has."

The screen went black.

The silence that followed was heavy, suffocating. Then, a single titter of laughter broke from the back of the room. It spread like a virus. Within seconds, the cream of New York society was laughing at me. The "St. Claire Princess" had been turned into a joke in front of the entire world.

I looked at Thatcher. He was backed away from me, his eyes wide with fear-not for me, but for his reputation.

"It was just one time, Elowen," he hissed, his voice low and frantic. "I was drunk. She came onto me."

"One time?" I looked at the screen, then back at him. My vision was blurring, my lungs refusing to take in air. "In our bed, Thatcher? With my sister?"

Bianca appeared from the wings of the stage, her dress perfectly pressed, not a hair out of place. She didn't look guilty. She looked like she'd won. "Don't be so dramatic, Elowen. We're all adults here."

My father stepped forward, his face a mask of cold pragmatism. "Elowen, stand down. We have a merger to sign. This... this can be handled privately."

"Handled?" I choked out. "She's my sister! He's my fiancé!"

"He is the man who is keeping us out of bankruptcy," Arthur St. Claire snapped. "Apologize to Thatcher for making a scene and sit down."

The room spun. My own father was siding with the man who had just publicly humiliated me. I looked around the room, at the sneering faces and the flashing cell phone cameras. I was the joke of the century.

I turned around and walked.

I pushed through the heavy gold doors, my heels clicking like gunshots on the marble. I didn't stop at the coat check. I didn't stop for the paparazzi waiting outside. I walked straight into the freezing New York rain, the white silk of my dress instantly soaking through, turning translucent against my skin.

A black Maybach sat idling at the curb, its tinted windows reflecting the neon lights of Fifth Avenue. I knew that car. Everyone in the city knew that car. It belonged to the man who had methodically dismantled my father's company, piece by piece, until we were nothing.

Killian Blackwood.

The back window rolled down slowly. The light from the streetlamps hit his face-all sharp angles and cold, predatory eyes. He looked like a god carved from obsidian.

"Going somewhere, Little St. Claire?" his voice was a low, dark rumble that vibrated in my chest.

I stopped at the edge of the car, the water dripping from my hair. "You were there. You saw it."

Killian leaned back, a glass of amber liquid in his hand. "I wouldn't have missed it for the world. It was a masterpiece of humiliation.

Though I must say, I expected more fire from you."

"I want them dead, Killian," I whispered, my voice trembling with a rage so hot it felt like it would consume me. "I want them ruined. I want them crawling through the dirt."

He arched a dark eyebrow, his gaze raking over me, lingering on the way the wet silk clung to my breasts. "And why would I help you? I'm the one who put the dirt there in the first place."

"Because you hate them as much as I do," I stepped closer, my hand trembling as I touched the cold metal of the car. "And because I'll do anything."

Killian went still. The air between us suddenly felt charged, heavy with a tension that made my skin prickle. "Anything is a dangerous word, Elowen. Especially when spoken to a man like me."

"I don't care," I said. "Name your price."

He stared at me for a long beat, his eyes tracking a raindrop as it slid down my neck. A slow, cruel smirk spread across his lips.

"Get in the car," he said.

I didn't hesitate. I pulled the door open and slid into the leather seat. The interior smelled of expensive tobacco and power. Killian didn't move away. He stayed right where he was, his large, powerful frame taking up half the cabin.

"The price is simple," Killian said, his voice dropping an octave. "You want revenge? You pay with your life. You move into my home. You work in my office. And when we are behind closed doors, you belong to me. Every inch. Every thought. Every breath."

"You want me to be your mistress?"

"Mistress implies a choice, Elowen," he reached out, his thumb catching my chin. His touch was electric, burning through my frozen skin. "I'm talking about total submission. I want to break the St. Claire pride until there is nothing left but your need to please me. Do you understand?"

I looked into his steel-blue eyes and saw the devil looking back. But then I thought of Thatcher's face. I thought of Bianca's smirk.

"Yes," I whispered.

"Good," Killian leaned in, his lips inches from my ear. "Then prove it. Prove you're desperate enough."

He reached down, his hand sliding up the soaked silk of my skirt, his fingers grazing the sensitive skin of my inner thigh. I gasped, my back arching as the heat of him collided with my cold flesh.

"Right now?" I breathed.

"I don't wait for what I've bought," Killian murmured, his hand moving higher. "The driver is focused on the road. The glass is soundproof. Show me how much you want them to burn, Elowen. Show me right now."

I leaned forward, my heart hammering against my ribs, and reached for the buckle of his belt.

"Don't make me wait, Little St. Claire," he growled.

I didn't.

Elowen's POV

The Maybach felt less like a luxury vehicle and more like a rolling confession booth. Outside, the rain lashed against the glass, blurring the lights of a city that was currently laughing at my ruin. Inside, the air was thick with the scent of Killian's expensive cedarwood cologne and the sharp, metallic tang of my own fear.

My hand didn't just tremble as I reached for his belt; it shook with a violence that made my joints ache.

"Tick tock, Little St. Claire," Killian's voice was a low, jagged rumble in the dark. "The longer you hesitate, the more Thatcher wins. Right now, he's probably celebrating his 'mistake' in Bianca's arms. Are you going to let him have the last laugh?"

I looked up, meeting his silver-blue eyes. They weren't cold-they were burning. A dark, voyeuristic heat that made my skin prickle under the soaked silk of my dress. He wasn't comforting me. He was watching me fall, and he was enjoying every second of the descent.

"I'm not hesitating," I whispered, my voice cracking. "I'm savoring the moment I finally stop being the girl who says 'please'."

I flicked the buckle. The metal clicked-a sharp, final sound that signaled the end of my life as a St. Claire. Killian's hand didn't go to my waist or my hair. Instead, he reached out and wrapped his fingers around my throat.

It wasn't a choke, but a claim. His thumb pressed against my pulse point, feeling the frantic, hummingbird beat of my heart.

"You're lying," he murmured, leaning so close I could feel the heat of his breath against my lips. "You're terrified that you're going to like this. You're terrified that the monster who broke your father is the only one who can make you feel alive tonight."

"Go to hell, Killian," I breathed, even as I leaned into his touch.

"I'm already there, sweetheart. I've been waiting for you to join me."

His hand tightened slightly, forcing my head back against the leather seat. His other hand found the hem of my dress, sliding up my thigh with a ruthless efficiency. The contrast was a shock to my system-his skin was burning hot, while I was still shivering from the rain.

When his fingers brushed against the lace of my underwear, a jagged spark of electricity shot straight to my core. I gasped, my back arching, my fingers digging into the hard muscle of his thighs.

"Look at me," he commanded.

I opened my eyes, my vision blurred by tears I refused to let fall.

"This isn't romance," Killian said, his eyes tracking the way my chest heaved. "This is debt. This is you paying for every lie your father told and every penny Thatcher stole. If you want me to destroy them, you have to be destroyed first. Do you understand?"

"Destroy me then," I challenged, my voice a ragged edge of defiance. "Just make sure there's enough of me left to watch them bleed."

A slow, cruel smirk spread across his face. He didn't kiss me. He didn't offer the mercy of a distraction. He kept his eyes locked on mine as he moved his hand, his touch demanding and precise.

The shame was a heavy weight in my gut, but beneath it, something else was waking up. A dark, hollow craving I'd never felt with Thatcher. With Thatcher, everything was soft, polite, and boring. This was a war.

Just as the car slowed to a halt in the bowels of his private garage, the tension in my body snapped. A sharp, breathless cry escaped my throat, swallowed by the sound of the engine cutting out.

Killian didn't pull me into his arms. He simply let go of my throat and sat back, his expression returning to that of a bored king.

"Out," he said, adjusting his cuffs. "The show is just beginning."

The elevator ride to the penthouse was silent. I stood in the corner, my wet dress clinging to me like a shroud, feeling the phantom heat of his touch on my skin. When the doors opened, I wasn't met with a home. I was met with a fortress.

Black marble. Glass walls that seemed to disappear into the midnight sky. It was a cold, beautiful vacuum.

"Marcus," Killian called out as he headed for the bar.

The man who appeared from the shadows looked like he'd been carved from the same granite as the walls. "Sir."

"Take her to the East Suite. Lock the digital bypass. She's a ward of the state now-my state," Killian poured a glass of scotch, the amber liquid glinting in the dim light. "If she tries to use a phone, I want to know. If she cries, let her."

"Killian-" I started, stepping toward him.

He turned, the glass halfway to his lips. "It's 'Mr. Blackwood' when we're in public, Elowen. And in private, well... we'll settle on a name when you've earned the right to speak it."

He looked at Marcus. "Get her cleaned up. I want her in my office in ten minutes. We have a contract to finalize, and I don't sign until I've seen the fine print on her skin."

Marcus led me down a hallway that felt a mile long. The room he shoved me into was a masterpiece of minimalist cruelty. On the bed lay a single garment-a black silk slip that looked like it would tear if I breathed too hard. Beside it sat a thick, black leather folder.

I didn't wait. I stripped off the ruined Vera Wang, leaving the white silk in a heap on the floor. It looked like a dead bird. I pulled on the black slip, the fabric feeling like a cold hand against my skin.

I picked up the folder.

CONTRACT OF TOTAL SUBMISSION

The words blurred as I read the clauses. Total access. Zero privacy. Mandatory compliance. At the bottom, in red ink, was a clause about my brother, Leo. Medical care contingent upon Party B's satisfactory performance.

He had my brother. He had my life. And he had my rage.

I signed it. Every page. Every line. I pressed the pen so hard the paper tore on the last signature.

There was no knock. The door simply slid open. Killian stood there, his shirt discarded, his torso a map of dark, intricate tattoos that seemed to move in the low light. A serpent coiled around his ribs; a crown of thorns circled his bicep.

"Is it done?" he asked, his gaze raking over me in the black silk.

"You have your pound of flesh," I said, tossing the folder at his feet.

He didn't pick it up. He walked into the room, the air pressure changing as he approached. He stopped so close I could smell the scotch on his breath and the raw, masculine scent of his skin.

"You look like a funeral, Elowen," he murmured, his hand reaching out to catch a lock of my damp hair. "Whose death are we celebrating tonight? Thatcher's? Or the girl you used to be?"

"Both," I said, my heart drumming a frantic rhythm against my ribs.

Killian's hand moved from my hair to the strap of the slip. He hooked his finger under it, pulling it slowly down my shoulder. "You think you're so brave. You think this is just a game of revenge. But you're missing the most important part of the contract."

"What's that?" I breathed.

He leaned down, his lips brushing the shell of my ear, his hand sliding down to the small of my back to pull me flush against his hard, tattooed chest.

"I don't just own your time, Elowen," he whispered. "I own your pleasure. And from this moment on, you only feel what I tell you to feel. You only peak when I give you permission. And I am a very, very stingy man."

He shoved me back onto the bed, his eyes flashing with a dark, terrifying intent.

"Strip," he commanded. "I want to see exactly what I bought before I start breaking it."

The phone on the nightstand buzzed-a notification from a news app.

BREAKING: ST. CLAIRE HEIRESS DISAPPEARS AFTER GALA SCANDAL. SPOTTED IN BLACKWOOD MAYBACH.

I didn't look at the screen. I looked at Killian, my hands reaching for the hem of the black silk.

"Don't make me wait, Little St. Claire," he growled. "You're on my clock now."

Elowen's POV

The silk slip hit the floor with a soundless rustle, leaving me exposed under the harsh, cold lights of the penthouse suite. I stood there, trembling not from the cold, but from the raw, predatory weight of Killian's gaze. He didn't move. He didn't rush. He just stood there with his arms crossed over his tattooed chest, dissecting me like I was a piece of art he'd bought at a discount.

"Turn around," he commanded. His voice was a low, velvet rasp that sent a traitorous shiver down my spine.

I gritted my teeth, my nails digging into the palms of my hands. "You've seen enough, Killian. Sign the medical release for Leo."

"It's Mr. Blackwood," he corrected, his eyes narrowing. "And I'll sign it when I've verified the quality of the merchandise. Turn. Around."

I swallowed the bile rising in my throat and did as he said. I felt his eyes roaming over the curve of my back, the line of my hips, the marks where Thatcher's hands had been only hours before. I felt like a sacrificial lamb, but the fire in my gut-the need to see the Montgomery empire turn to ash-kept my knees from buckling.

Suddenly, his heat was right behind me. He didn't touch me at first, but the air between us was electric, thick with the scent of scotch and something darker, more primal.

"Thatcher was a fool," Killian whispered into my ear. His breath was a warm contrast to the icy fear in my blood. "He had a thoroughbred and he treated you like a pony. No wonder you ran to the devil."

"I didn't run to you," I snapped, turning my head to glare at him over my shoulder. "I recruited you. There's a difference."

Killian let out a dark, dry laugh and finally placed his hands on my waist. His fingers were large, calloused, and bruisingly firm. He pulled me back against him, the friction of his rough skin against my soft flesh making my breath hitch.

"Recruited? Is that what you're calling this?" He spun me around, his grip moving to my shoulders as he pinned me against his hard frame. "You sold yourself, Elowen. You didn't just sign a contract; you gave me the keys to your body. And I intend to drive you until you break."

"Then do it," I challenged, my emerald eyes clashing with his silver ones. "Stop talking and do it. Or are you all talk, Mr. Blackwood?"

His expression shifted from cold amusement to something lethal. In one swift motion, he lifted me, my legs instinctively wrapping around his waist. He slammed me back against the bedroom door, the impact jolting my spine.

"Careful, Little St. Claire," he growled, his face inches from mine. "You're playing a game you don't understand. I don't give. I take. And I take exactly what I want, when I want it."

He crashed his mouth onto mine. This wasn't the polite, guarded kissing I'd shared with Thatcher. This was a war. He bit my lower lip, demanding entry, and when I opened for him, his tongue invaded with a ruthlessness that left me lightheaded.

I hated him. I hated the way he'd ruined my father. I hated the way he looked at me like I was nothing. But my body was a traitor. My heart hammered against my ribs, and a shameful, honeyed heat began to pool between my thighs.

Killian groaned, his hands moving from my shoulders to my chest, his thumbs tracing the line of my collarbones before sliding down. He didn't tease. He didn't ask. He molded me with a possessiveness that made my head spin.

"You're already wet for me," he murmured against my throat, his teeth grazing the sensitive skin there. "Even with all that hate in your heart, your body knows who its master is."

"It's... it's just biology," I gasped, my head falling back against the door as his mouth moved lower. "It doesn't mean anything."

"It means everything," Killian said, his hand sliding down, his fingers finding the center of my ache with a precision that made my vision white out. "It means that while you're planning your revenge, your soul is screaming for the very man who destroyed you. Tell me, Elowen. Tell me you want this."

"I... I want my brother safe," I choked out, my fingers tangling in his dark hair, pulling him closer even as I tried to push him away.

"Lie again and I'll walk out that door," he threatened, his fingers moving with a rhythmic, torturous pace. "Tell me you want me. Tell me you need the monster."

The pleasure was a tidal wave, crashing over my pride and my dignity. I was drowning in it, in him. "Yes," I sobbed, my back arching off the door. "Yes, Killian. Please."

He stopped.

The silence that followed was deafening. I opened my eyes, my breathing ragged, my body humming with a desperate, unfulfilled need. Killian was staring at me, his eyes dark with a cruel triumph. He wasn't even breathing hard.

"Please what, Little St. Claire?" he asked, his voice deathly quiet.

"Don't... don't stop," I whispered, the shame of the words burning hotter than the rain outside.

Killian stepped back, letting my legs drop to the floor. I stumbled, my knees weak, forced to grab the door handle for support. He looked down at me, his smirk returning-the cold, billionaire smirk that had haunted my family's dreams for a decade.

"I told you in the car, Elowen," he said, reaching for his discarded shirt on the chair. "I am a very stingy man. You don't get the release you crave just because you asked for it. You haven't earned it yet."

"You... you can't be serious," I breathed, my face flushed with a mix of arousal and fury.

"I'm very serious." He buttoned his shirt with steady fingers, his gaze never leaving mine. "You're going to spend the night in this room, thinking about what you've become. You're going to feel every bit of that itch, and you're going to remember that I'm the only one who can scratch it."

He walked toward the door, picking up the signed contract from the floor.

"In the morning, a stylist will be here at six," he continued, his tone turning business-like and cold. "We have a press conference at the Montgomery Center. I'm announcing a hostile takeover of Thatcher's primary holding company. And you're going to be on my arm, looking like the happiest woman in the world."

"You're going to flaunt me in front of him?" I asked, my voice trembling.

"I'm going to show him exactly what happens to things he fails to protect," Killian said, opening the door. "Get some rest, Elowen. You're going to need your strength. The public part of your ruin begins tomorrow."

The door clicked shut, and I heard the unmistakable electronic chirp of the lock engaging.

I was alone. I was aching. And for the first time in my life, I realized that I hadn't just signed a deal with the devil. I had invited him in, and he was never going to let me go.

I walked over to the nightstand and picked up my phone. A new notification was sitting there-a picture Bianca had just posted to Instagram. It was her and Thatcher, clinking champagne glasses. The caption read: The right sister always wins. #NewBeginnings.

I threw the phone across the room, watching it shatter against the marble wall.

I didn't need a phone. I didn't need my father. I didn't even need my dignity.

I looked at the door Killian had just walked through. Tomorrow, Thatcher would see me. Tomorrow, the world would see me. And if I had to be used by a monster to make them suffer, I would be the most beautiful tool Killian Blackwood had ever owned.

But as I lay down on the cold silk sheets, my body still pulsing with the ghost of his touch, I knew the truth.

The war wasn't just between the St. Claires and the Blackwoods anymore. It was between me and the man in the other room. And I was already losing.
