Chapter 340

She was the only one that kept me sane in this house. Whenever she wasn’t at home, I’d feel like my world would fall apart. Her happiness and playfulness kept he alive every time. It was always too quiet and lonely whenever she went to see those friends of hers that I had come to hate with a passion.

Even though I had tried to come up with some solutions, like spending time in her room whenever she was out or holding onto her favorite toy just to pretend she was there with me, it still wasn’t enough.

“I can’t. I love my friends,” She pressed with sadness written all over her.

“More than you love me?” I asked, tilting my head while putting on wounded smile.

Her eyes shot up to meet mine in panic. “No! No, I love you, Kester. You’re my big brother. You’re everything to me, but…”

“But what?” I pushed softly.

She hesitated. And that hesitation was enough.

“You don’t need them. You can see them another time.”

I reached for her other hand and gave her my most hopeful grin. “Actually, I picked out a movie for us to watch tonight. One of your favorites.” I announced, hoping it would cheer her up, but it didn’t.

“I’ll massage your feet while we watch… Just the way you like it.”

Her lips twitched.

“And I was thinking,” I continued, squeezing her fingers playfully, “you could spend the night in my room tonight. It’s your turn to be hosted anyway, remember? You hosted me last week.”

I gave her a slow, knowing wink. “How does chocolate and popcorn sound?”

She let out a tiny breath. Her shoulders slumped as she sank back onto the bed with a reluctant smile curving the corner of her mouth. She was clearly displeased, but that was okay.

“Thank you, Kasmine,” I whispered, brushing a strand of hair from her face. “I promise you’ll see them another time. Okay?”

She nodded once, but that was enough for me.

SIX YEARS AGO.

“Kester! Are you trying to kill her?” Norlan snarled through gritted teeth, gripping my arm in an attempt to stop me, but he couldn’t. I was far too lost to be stopped.

“She asked for it, damn it!” I hissed, my fingers digging into Jeni’s waist as I pulled her closer, slamming my cock into her harder.

She yelped at the impact, gripping tightly on the table on which she was bent over as I fucked her from the back. Her legs were almost giving way, but I held her firmly.

“Please, Kester…” She gasped when I slowly rolled my waist, my cock swirling, teasing, and rubbing the corners of her insides before I buried myself to the hilt again.

Chapter 340

She whimpered.

I wrapped her half around my fingers and pulled hard, making her ah her back, giving me the most wicked angle there was as my balls slapped loudly against her wet entrance, and fuck, it was addicive. She was petite, tight, and zo wet it was phiscene. And I Toved ruining her.

“Fuck!” Norlan cursed and returned to the window, staring outside af trying to go back to minding his business.

He was clearly displeased. He knew exactly why I was doing this. But hadn’t he been the one who’d advised me to take out the steam on another girl instead of losing control and fucking my sister

He said I should channel it somewhere else.

And here I was, channeling. Why was he now worried?

It was our final year in college, and we had just a few weeks to graduation. Jent, the school’s most cherished student, had vowed to have me before graduation.

She had been on my neck for three years now. And today, I had to grant her wish, even though I was only using her to pour out my frustration.

My little sister was growing up too fast. And it was killing me. She was becoming a beautiful young woman with a body built like a goddess.

At 15, she was already looking like a runway model with cleavages and curves appearing in the right places and proportions.

She wore little things around the house… Tiny shorts, loose tops, and no fucking bra!

I’d tried to caution her about the kind of things she wore around “the house” several times, but she wasn’t getting the memo. I wasn’t concerned about “The House.” I was concerned about ME!

I know I should be disgusted at myself for even noticing, but whenever she wore those little, tight clothes of hers that barely covered her body, they made me really uncomfortable in the wrong way.

It began to grow worse to the point that I intentionally began avoiding her. We had to cut down greatly on our movie nights, including spending nights in each other’s rooms.

Fuck, I even had a hard–on for her on some occasions.

Hell, it was never her fault.

But I was slipping. I was rotting from the inside out with how much wanted her.

The feeling was becoming unbearable. But I could never bring myself to doing anything that wild with a–fifteen–year–old, let alone my little sister.

So, here I was, with an easy prey, letting out the steam Kasmine had ignited in me last night when she came into my room in one of those big shirts she mostly puts on… The one that barely covered her ass.

And that wasn’t all. She was freaking looking for a stupid hair band knew nothing about.

I told her it wasn’t there, but she didn’t listen.

She bent down right in front of me to check under my closet.

And fuck…!

Her shirt lifted.

She… She was… Fuck!

I fucking saw her pussy! It was as clear as day! And that drove me to the brink of madness.

I stopped breathing. My jaw clenched so hard I thought my teeth would crack.

She was fifteen, for fuck’s sake!

My thrusts became more rapid and urgent, as if I could tear the memory free just by fucking harder.

The picture of Kasmine bent over and exposing her bare pussy to me clouded my mind. And no matter how hard I tried, that image had burnt itself into my memory, and since last night, I stopped looking at her the same way I used to.

She was too free around me. She trusted me way too much. And that trust was going to be my fucking downfall. I didn’t need a soothsayer to tell me that.

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.”
