Chapter 369

FIVE YEARS AGO.

KESTER.

It wasn’t working. I had done everything and I mean everything.

I’d bugged her phone, tracked her calls, read every damn text she ever recieved. Her computer? It was mirrored to mine. I could see what she saw, click for click.

I even installed keyloggers on her fucking laptop. I knew what she Googled. I knew what she deleted, I knew everything

I stalked her. No apologies. Every day. Every fucking step. Wherever she went, I wasn’t far behind, to make sure she wasn’t meeting up with any of those boys I warned her not to meet.

No more Nathan. No more James. No more smiley little fuckers in her life. I made sure every guy that so much as looked at her twice backed off and stayed away. I built a fucking wall around her.

I had successfully made every boy around her scared of her. She literally didn’t have any male friends anymore.

I watched her every fucking day through the hole on the wall, breathing her in. The other day, I even saw her attempt to give herself a little, curious rub around her panties, but she didn’t even know how to, or what her body wanted, so she gave up, clearly frustrated. She pulled her nightgown back down and curled into her blanket like she was embarrassed.

She didn’t know I was watching and that I was dying.

That view – that fucking perfect view of her on her back, hair spread on the pillow, thighs just barely parted – it almost destroyed me.

Fuck. It took every ounce of self control in me not to barge into her room and fuck her tight little pussy with my fingers until she begged me to insert my cock in there.

I almost lost my mind that night.

I’d imagined too many times, those trembling fingers of hers, replaced with mine. My hand forcing her legs apart with my voice in her ear, telling her exactly how to touch herself, or better yet, letting me do it for her.

Her bed was positioned in a way that gave me the perfect view. Even though I couldn’t have a clear view of what her pussy looked like, my imagination didn’t need help anymore. I’d already filled in the blanks while I looked at her parted thighs. Her pussy was still untouched – tight, wet, and virgin–soft.

Fuck.

I’d jerked off to her more times than I could count. Some nights twice. Other nights, more. I didn’t feel guilt anymore. Just hunger, obsession,

and need.

But I still wasn’t satisfied. A part of me still felt empty. Totally empty.

What I wanted was simple… I wanted to own her totally. Chasing boys away from her didn’t do the trick anymore. I wanted her to be mine and mine alone. And I wanted her to know that she was mine.

I wanted to have access to her body. I wanted all of her. Her time. Her body. Her mind. Her fucking soul.

I wanted to crawl into her world and seal the exit shut.

I didn’t want her to be just afraid of me. I wanted her owned. I wanted her to understand that she wasn’t hers anymore.

Chapter 369

She was mine.

I wanted to do so many unholy things to that gorgeous body of hers. And I wanted her to thank me for it.

She was already terrified of me. The other day, she said I wasn’t the big brother she used to know.

Damn right, I wasn’t.

That part of me died a long time ago.

I had become cold and distant. I hardly ever said much to her, or even looked at her for longer than five seconds.

I didn’t want to lose it.

I had become Alpha. And I had taken over my father’s company. I made a decision I know would be beneficial for us all. I’d be leaving town. Three hours away from home.

–

Maybe just maybe I’d outgrow this… madness. This obsession that had sunk its teeth into my spine and refused to fucking let go.

June had been on my neck nonstop. Always trying to squeeze herself into the space Kasmine filled. Maybe if I gave her a shot, she’d be enough of a distraction to make me forget about Kasmine.

The door to my room pushed open ever so slowly, and I already knew who it was.

She cleared her throat and asked, “Can I come in?”

I didn’t even look back. I kept folding my clothes and dumping them into the open suitcase on my bed.

Sure. Come in.” I replied.

I felt her soft presence drawing nearer to me, and her fragrance?

Fucking hell. Sweet, fresh, and stupidly addictive.

“Stop,” I snapped, turning toward her before she crossed the invisible line I set for myself.

Her eyes widened, and I could practically taste the fear leaking from her.

As usual, she was putting on her usual crop top and skimpy Jean short that barely covered her ass cheeks.

Her thighs were glowing. Her skin was soft, and those damn shorts were tight enough to make a priest lose focus.

Did this girl want to get fucked?

I’d warned her not to wear such clothes anymore around the house. But she never ever listens. She was sometimes way too stubborn for my

liking.

Her fingers were intertwined together with her hands at her back, all shy and innocent, like a little girl about to ask for a new toy. And that posture? Fuck. It pushed her boobs towards me like a fucking invitation. And her nipples? Round and hard like stones, poking through the fabric of her top like they were trying to say hi.

I forced my eyes to stay on her face. “What?” I bit out.

“I…” she cleared her throat and swallowed, “I just came to

say goodbye… And that I’d miss you.”

Lies.

Chapter 369

I knew she wouldn’t miss me. I was certain she was excited that I was leaving. Now she could finally talk to these other prys 1 scared away. Probably couldn’t wait for me to leave and give her the fucking freedom she always secretly wanted.

“Alright. Be good.” I said, still holding her nervous gaze.

She still stood there, unable to meet my gaze. Did she want something else?

“Wha…” I was just about asking what else she needed when, like a flash of light, she closed the distance between us and wrapped her arms around my waist, burying her face in my chest.

“I’ve missed you, Kester,” she mumbled into me. “And I’ll miss you even more.”

I stood frozen, fists clenched at my sides. I could feel her warmth, her heartbeat, the soft drag of her fingers clutching my shirt.

Was she crying?

“Kasmine…” I whispered. I didn’t mean to. But it just came out.

“Please stay safe out there, Kester. No matter what happens.”

And just like that, she fucking ruined me again. Because staying safe became an assignment and a responsibility to me. Because, no matter what I did, I always remembered that I had to stay safe for her.

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.”
