Chapter 50.

KESTER.

I had lost my mind completely. The first moment I saw her

1 should’ve left. Turned away. But my feet wouldn’t move. couldn’t. I was paralyzed by the sight of her–her mouth, so fucking cager, swallowing him whole like it was nothing

She was, giving herself to that fucking asshole; her eyes closed, totally lost in it. And I just stood there, watching Helpless. So fucking helpless.

My heart slammed against my ribs, but it wasn’t anger that hit me first. It was hurt. A raw, gut–wrenching pain, something that ripped through me, shattering whatever fudding control I thought I had left.

I could feel the anger rising, boiling under my skin, the sickening burn of jealousy twisting my insides into knots.

I wanted to break something. Anything But most of all, I wanted to break her–to make her see that she couldn’t do this. Not with him. Not with anyone.

Seeing her frozen in place as she saw me only fueled my anger. I didn’t want to hurt her…. I didn’t want to. I had to keep my twitching fingers in place.

“Cat got your tongue?” I asked in all the calmness I could muster before standing up, “Hmm?” I took slow strides toward her, making sure she felt every ounce of the stormy anger brewing inside of me.

She wanted to step back, but she hit the wall behind her. If she thought for one second that I was going to hit her or do anything harmful to her, then she was mistaken.

She was shaking.

The closer I got, the more I saw the slight tremble in her hands. Her pupils were blown wide, panic spreading like cracks through the ice, but she didn’t move. Couldn’t move.

Good

She was scared.

I liked that

Because I wanted her to be. Fuck, yes. Because it meant something. Because it meant she understood–finally fucking understood that what she had done wasn’t something I could forgive.

That I was never going to let it go.

Texhaled slowly, willing the storm inside me to settle. The fury, the jealousy, the raw fucking ache of seeing her with him it had dragged me so deep into the dark that I wasn’t sure I could crawl back out.

1 lifted my hand.

She flinched, and it stopped me for a second.

I had never hurt her before… Would never hurt her.

But her body thought I would.

Her mind flooded with guilt, thought I would.

1 brushed my fingers against her cheek. Soft. Gentle. The way a lover might

She was burning up

A fever of fear and guilt. I could feel her pulse hammering under my fingertips, her skin so fucking hot it felt like she might combust from my touch alone.

I leaned in, just a fraction, so that she could hear the quiet, deathly control in my voice.

“Go into the bathroom.” I paused, letting my thumb drag lazily across her cheek, my voice lower, quieter, so she had no choice but to listen. “Brush. Bathe. Freshen up.

She wasn’t breathing

I smirked at that.

“And

I wasn’t even touching her anymore, but she was frozen. I leaned even closer, my lips so close to her ear, when you’re done…” I murmured, “Lay down. And don’t even think about closing that door before you sleep.”

KASMINE.

I was terrified to death. Kester issued the instructions and walked away without another word.

What was he planning?

I reached for our secret phone and ran into the bathroom, calling Jake for the tenth time after Kester left my room but he was still not answering the call.

My hands were shaking so badly I could barely grip the phone. My breathing was all over the place. I was dying Had Kester harmed him already? I hope not. Otherwise, I won’t forgive myself for it.

I tried dialing one more time, pressing the phone so tight against my ear I could hear my own pulse thrumming through my skull. Nothing

I heard my door open with a force that made my phone fall from my hands. I panicked, picking it up immediately. I looked for the best possible place to hide it, but there was none.

“Kasmine?” Kester called. His voice was calm. Too calm. The kind of calm that chilled me to the bone. He was walking toward the bathroom as if he knew I was there.

Sometimes, I was tempted to think that Kester was watching me through some magic means or something… He always seemed to know what I was doing or where I was at.

I looked around frantically, searching for somewhere–anywhere–to hide the phone. Under the sink? No, it’s too open. We cabinet? Too obvious. The fucking bathtub? No time.

The footsteps were getting closer.

Shit

I only had one option.

Fingers fumbling, 1 yanked at the knot in my towel, unraveling it in a desperate motion. The phone disappeared into the thick folds of fabric, and without thinking, I tossed it behind the door just in time-

The door burst open.

And I was standing there.

Naked.

For a split second, everything went still.

Kester’s eyes landed on me. His gaze dragged down my body, slow, dark, lustful. A muscle ticked in his jaw.

He stepped forward.

I stepped back.

My back hit the cold tiles, the shock of it making me shudder. His expression didn’t change.

He kept coming.

I swallowed hard, attempting to press my arms against myself in a weak attempt to cover up, but it was useless.

“Kester “My heartbeats collided with a crash. His presence was beginning to burn.

I never felt more exposed in all my life. No man had ever seen me naked. Let alone my brother.

A shiver ran down my spine–not from the cold, but from the way his green eyes darkened further, his gaze dragging over me in slow sweeps. My stomach twisted. My skin prickled under his stare, every inch of me hyperaware of him, of his presence, of the way he stood so still yet commanded every bit of space between us.

My arms twitched again in a desperate urge to cover myself–but I stopped. Because the second I moved, his eyes flicked up to mine.

Daring me.

“Don’t you dare…” He counted his words, and I swear I could hardly recognize his voice. “Come.” He said simply and left the bathroom. 1 hesitated but followed him into the room.

As soon as we were in, he reached for my wrist and grabbed me gently, pulling me toward the bed. His touch was too gentle. Where had all the anger gone? Wasn’t he meant to scold me or possibly kill me by now?

My feet moved anyway, following him like I had no will of my own.

The moment we reached the bed, he released my wrist and looked at me–really looked at me like he was drinking me in.

“Kester…” I whispered, but my voice barely made a sound.

His jaw clenched. One would think he was angry, but he wasn’t angry. No, this was something else. Something darker. Far more dangerous than anger. It was an intent, and it terrified me.

He gave me the slightest nudge, and I understood but hesitated.

“Now, Kasmine.” He commanded. His hands–still unbearably gentle–pressed against my shoulders, guiding me back until my bare skin met the sheets. My body stiffened.

I moved to cover myself, my hand instinctively crossing over my chest and the other placed above my center. Beneath his sweats was a thickness that againwas impossible to ignore, even to the blind.

His head tilted, his expression darkening as his gaze pinned me in place. “Don’t you dare,” he warned again.

I swallowed hard.

I couldn’t breathe. I couldn’t move.

And then he took a step back. His intense, predatory eyes scanned every inch of exposed skin. There was

something almost reverent about the way he watched me as if he were memorizing every detail, branding, me into

his mind.

Kester didn’t speak. He didn’t have to. The way he dragged his fingers down his bare stomach to the waistband of his sweats said enough.

His broad shoulders, solid like stone, flexed as his muscular arms with long, visible veins subtly pushed down his pants.

And I stopped breathing.

His erection sprang free, thick, hard, already straining as if he had been holding himself back for too long. His strong thighs, which were built for control, stood firmly rooted to the ground.

A choked sound left my throat as I sat up, my entire body trembling.

“Kester…” I whispered, “What… What are you doing?” I asked breathlessly when the reality began to dawn on me.

He smirked, and for a moment, I didn’t recognize the man standing before me.

I shifted

out of Sperately backward, even though I was going deeper into the same space I knew I should be running

out of, but it was the only possible way away from him I could go for now… “Kester?”

“Tonight, I will finally make you mine, Kasmine. I hope you have what it takes to bear it.”

My Stepbrother

Synopsis : My Stepbrother

Kasmine’s world shattered the night she witnessed her stepbrother, Kester Hamilton—the Alpha of the Crescent Moon Pack—murder an innocent man in cold blood. What began as a normal evening in the woods turned into a nightmare that would haunt her forever. The man Kester killed was no threat; he had only been talking to Kasmine. Yet Kester justified the murder by claiming the man tried to force himself on her.

Trembling and terrified, Kasmine confronted him, refusing to believe his twisted explanation. But Kester’s demeanor remained disturbingly calm. He didn’t show an ounce of remorse. Instead, he scolded her for being dramatic and tried to drag her back to the party, as if nothing had happened. When she resisted, he unleashed his Alpha command—a power no wolf could defy. Under his control, Kasmine’s will crumbled, and she obeyed him like a puppet.

As she returned to the party—ironically, Kester’s girlfriend’s birthday celebration—Kasmine’s heart broke. The brother who once protected her now scared her more than anyone else.

Her mind drifted back to her childhood, to the days when Kester had been her hero. After her father’s death, her mother remarried Alpha Kade Hamilton, Kester’s father. At the time, Kester was fourteen and Kasmine was only seven. He took her under his wing, treating her like a precious little sister. He brought her gifts, defended her from bullies, and made her feel safe. To everyone around them, Kester was the perfect big brother.

But as Kasmine grew older, that “protectiveness” became something else—something dark and possessive. By the time she turned sixteen, Kester had started isolating her from others. He didn’t allow her to have male friends, and even her time with female friends was limited. He wanted her attention, her trust, and her presence—all to himself. It became suffocating.

Now, at twenty years old, Kasmine had no boyfriend and barely any social life. Every time she tried to rebel, Kester reminded her that she should wait for her fated mate when she turned twenty-one and got her wolf. Her parents saw his control as love and protection, never suspecting how toxic and obsessive it had become.

After witnessing the murder, Kasmine was emotionally destroyed. She couldn’t eat, sleep, or think straight. The image of the lifeless man haunted her. Luckily, she only had to see Kester on weekends, since he was busy running both his pack and his billion-dollar company—Zamford Technologies. But even from a distance, his control continued. He had bugged her phone and laptop, monitoring every message and call. There was no escaping his watchful eyes.

Trying to focus on her studies, Kasmine pushed herself to attend her final year of college. She was preparing for her internship, and for once, she felt hopeful. She had submitted three company choices, deliberately avoiding Zamford Technologies to stay away from Kester. Her best friend, Jake—a guy she secretly liked—had applied to the same companies. She dreamed of being placed in the same one as him. Maybe then, away from Kester’s shadow, she could experience normal life, maybe even love.

That morning, she rushed to campus, still hopeful about the internship results. At the school entrance, she met her best friend, Claire, who looked visibly upset. Claire confessed she had been posted to J&F Technologies. Her disappointment wasn’t about the company—it was about Kester. Claire had nursed a crush on him for years and had listed Zamford Technologies in hopes of working near him. But her wish had failed, and she’d lost her chance.

Trying to comfort her, Kasmine asked about her own posting. Strangely, Claire didn’t answer, avoiding her eyes. Confused but impatient, Kasmine dragged her to the information board. Her heart raced as she scanned the list, looking first for Jake’s name. He was placed at Plush Technologies—one of the options they’d chosen together.

Excited, she searched for her name next, praying to see it under the same company. But her excitement quickly turned to dread. Her hands trembled. Her breath caught in her throat. There, beside her name, was written: Zamford Technologies.

The world seemed to tilt around her.

It couldn’t be real. There had to be some mistake. How could she, of all people, end up at her stepbrother’s company—the very place she’d tried hardest to avoid? Panic rose in her chest as the realization sank in. Kester must have done this. Somehow, he had found a way to manipulate her placement, ensuring that even in her professional life, she couldn’t escape his grasp.

Her mind flashed back to his piercing green eyes, his dominating voice, the way he’d ordered her around after committing murder without remorse. Now, he would have full control over her again—for hours every day. There would be no hiding, no breathing space.

As she stood frozen before the board, Kasmine felt her fragile hope for freedom crumble. She had spent years yearning for the day she could make her own choices—turn twenty-one, find her fated mate, and escape Kester’s suffocating hold. But now, destiny—or rather, Kester’s manipulation—had pulled her right back into his world.

And deep down, she feared that this time, she might not make it out alive.

Themes and Tone:
“The Alpha’s Obsession” explores the darkness behind overprotective love, the trauma of control disguised as care, and the pain of being trapped by someone who claims to love you. The tone is tense, emotional, and suspenseful, building a deep sense of dread as Kasmine realizes that every path she takes leads her back to the same monster she once called “brother.”
