Chapter 20

KASMINE.

I searched his eyes for any form of understanding, but there was none. All I saw was a cold, unfeeling man. It felt like I was standing before a stranger… Someone who fed on control.

“Kester!” My voice cracked, raw with desperation, as I tried to twist out of his iron grip. It was useless. He didn’t even flinch, his smirk widening as he watched my futile struggle. His calm, collected demeanor only made my panic worse.

“I’ll do anything you want. I swear. Just let me go,” I cried.

Tears rolled down my eyes.

He tilted his head, “Anything?” He asked so casually, and I nodded frantically, my mind

spinning.

“I’ll never miss work again,” I choked out, the words tumbling over one another in my desperation. “I’ll never disobey you, Kester. I’ll do your laundry. I’ll cook for you… I’ll do anything… anything. Please. Just don’t do this to me.”

Tears streaked my face, my chest heaving with sobs. The thought of my mother seeing me like this, of her finding out what was happening, shattered me. She would be devastated if she ever saw me with a man, let alone my stepbrother. It’ll break her poor heart. She would never forgive me.

“Anything…” he murmured, his gaze a bit distant as if lost in his thoughts.

“Yes. Yes.” I whispered.

I heard my mum opening Kester’s room and calling out his name. My room would be next, and she was just too close to opening my door.

“I noticed you’ve been locking your door a lot lately,” he said, his tone casual, but his eyes told a different story. They pinned me in place as his fingers traced a lazy path down my cheek, “I don’t think you’d want to lock it tonight. Would you, Kasmine?”

My throat closed, my breath catching.

“I-” My voice faltered.

I wasn’t stupid. I didn’t expect him to explain what he meant.

That was him saying, ‘Kasmine, keep your door open tonight.‘

But it terrified me. I didn’t think it was something I’d like to do. What if he… What if…

He leaned closer, his lips brushing my ear as he whispered, “What happens if you lock it? Hmm? Shall we find out?”

I had begun locking my door after I saw the things I had seen in his room two days ago. It was my own little way of shielding myself from him.

“Kester…”

“I guess we don’t have an agreement, then,” He said and dipped his head to kiss me, but I nodded quickly.

“I’ll leave my door open tonight. I swear. I will.” I replied in a hurry, my eyes darting from him to the door, my chest heaving.

The knock I anticipated came. I flinched.

“Kasmine?” My mum called as she attempted to open my door.

“I swear to you, I’ll keep my door open,” My voice trembled.

“Good girl,” He said, stroking the side of my face as if he wasn’t even in a hurry. His gaze lingered on me for a moment, the intensity in his eyes making my skin prickle. “See you tonight, then,” He added softly. But why did his words sound more like a threat than a promise?

“You should answer her,” he said, his voice low and amused as he picked up his jacket heading towards the bathroom, “Wouldn’t want her to worry about you.”

He paused at the bathroom door, glancing back at me. “And don’t forget, we still have work today. I’ll wait in here as long as you need,” he said with a wink before disappearing inside, the door clicking shut behind him.

I knew what Kester meant. It was simple: ‘Get her out of here so I could leave.‘

The knock came a second time. “Kasmine? Are you in there?”

My voice was shaky as I called out, “Yes, Mom. I’m coming.” I cleared my throat, securing my towel properly around my chest. But as I stepped away from the wall with my legs unsteady, Kester’s words kept haunting me, reminding me of the chaos he’d unleashed if I ever went against him at any point.

I wiped my lips hastily, trying to erase any evidence of what had just happened.

Taking in a deep breath to calm my obviously trembling hands, I unlocked the door and pulled it open.

“Oh, Selene! Mum!” I feigned surprise, hoping I acted it out properly. “How? I mean… You

didn’t even inform me,” I hugged her. And somehow, I really did need that hug. My nerves

were a mess.

“Are you okay, honey? You seem a bit…” Her eyes hovered over me for a moment, and my heart skipped several beats, “Tense.” She added, but I rolled my eyes.

“I am fine. Just the internship and all,” I breathe out a sigh, “Let’s get you some juice,” I said, closing the door behind me.

“No, baby. I don’t need anything. Let’s just go inside,” She waved it off and made to open my door, but I stopped her instantly.

“No!” I shouted before I could even stop myself, “I mean… Yeah. But I also want a glass of juice. Join me. We have a lot to catch up on,” I didn’t give her the chance to protest before pulling her with me.

Mum was young and beautiful. She had me when she was twenty–two. And the goddess had blessed her with beauty and an amazing, ageless body. That’s something I always pray for. To an extent, Selene answered those prayers. I looked just like my mom.

“Why aren’t you in the office already? Is this how you’ve been behaving? And your brother lets you do as you please?” There she goes. Nagging again over nothing.

I rolled my eyes as I took a sip out of the glass of juice before leading her upstairs to my room. With the delay tactics I used in the kitchen, Kester should have had enough time to leave my room already.

“Kasmine. This is past eleven!” She pointed out, and I scoffed.

If only she knew the other reason for the delay… If only she knew my brother had almost fucked me if she hadn’t arrived just in time to save me.

“Mum, I already told you before, I…” My words stuck in my throat when I pushed my door open and took in the sight before me.

“Hello, mum. Welcome to our house.”

It was Kester.

What the fuck was he still doing in my room?

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.”
