Chapter 25

KASMINE.

Today was the day I was meant to die from a heart attack.

I had pleaded with Jake to let me get off the call and that we would speak more about this ‘surprise‘ he said he had for me over lunch tomorrow, but he refused. Now, imagine the surprise I got when Kester barged into my room unannounced.

It was almost as if he had heard or seen me talking to Jake with the way he barged in.

Now, here I was, kneeling and crying at his mercy to save the one I truly loved.

But what did he want from me? What would he have me do to prove all he just said?

I wasn’t his. I’d never been his. I didn’t want to be his. I want to be Jake’s.

Whatever delusions or fantasies he harbored about us in that dark, possessive mind of his, none of them were real. Kester remains my stepbrother, and no matter what he says or thinks, calling me MINE doesn’t make me HIS. But the way he looked at me now, as if I was something he’d already claimed, made me doubt if I could escape his reality.

I was still trying so hard to process the kiss from this morning. I was still embarrassed and confused as to why he’d kiss me. And now, this?

My gut tells me Kester was up to no good with the way he was looking at me.

My nightie would certainly be a recipe for the disaster that would befall me tonight. It was so transparent that you‘ didn’t need to squint your eyes before you got a good view of what lay beneath.

The hem barely reached mid–thigh, exposing far too much of my legs. The deep V–cut neckline framed my cleavage, leaving nothing to the imagination. His cold stare made my blood run cold while a shiver traveled through my spine.

A tear trickled dow

my cheek, tracing the curve of my jaw before slipping into the valley between my breasts. His eyes followed it, unblinking, until the drop disappeared into the fabric.

“Kester…” I whispered, but he didn’t respond.

Instead, he stood up, towering over me, and reached for the knot of his drawstring shorts,

My heart thundered. I couldn’t look away as his fingers worked the knot, undoing it with intentional slowness, his eyes never leaving mine.

“What… what are you doing?” I choked out, my voice barely above a whisper, trembling with panic

He didn’t answer. He didn’t even blink.

The shorts slipped down his legs, pooling around his feet, leaving him in only a pair of black briefs that clung to him in a way that made my mouth go dry. I tore my gaze away, heat flooding my cheeks as I tried to focus on anything but the outline beneath the fabric, which hugged every ridge of his hips, his thighs, and the terrifying hardness pressing against the front.

My stomach dropped. I scrambled backward, the plush rug beneath me doing little to muffle the frantic shuffle of my knees. “What the hell are you doing?” My voice rose, breaking with panic as my hands shot up in a feeble attempt to shield myself.

Chapter 25

“Stop,” I managed, my voice weak, my hands pressing against the floor as I tried to inch away. “Kester, stop this

He moved. Not toward me, but toward the door.

I froze, my confusion mixing with fear as he reached for the lock, twisting it with a resounding click.

“Kester, please,” I begged, my voice cracking. My hands curled into fists against the floor, my nails digging into my palms as I fought to steady my breath. “You don’t have to do this.”

He turned back to me, his expression unreadable, a dangerous calm radiating from him. Slowly, he walked toward me, each footstep making my pulse spike.

When he reached me, he crouched, his face inches from mine. His hand shot out, gripping my chin with a roughness that made me flinch.

“You don’t get it, do you?” he murmured, his voice low, smoky, and filled with an edge that sent a tremor down my helpless spine. “I always get what I want.”

His thumb brushed against my trembling lower lip, the tough possessive, almost cruel. “And what I want, Kasmine…” His eyes darkened, his gaze locking with mine. ‘Is You. And you will prove to me that you understand that.”

Why would he want me? This was all insane, He was no longer the big brother I used to know.

What happened to my big brother?

“Kester, 1-”

“Shh.” He cut me off, his other hand trailing up, brushing the strap of my nightgown.

I watched him stand to his full height again, and this time, he took his extreme joke a bit further..

With a swiftness too quick for me to comprehend, he pulled down the fabric that harbored his cock.

“Kester! No!” I screamed, looking away instantly as I jerked up to my feet, taking desperate steps away from him until my back collided with the wall behind me.

My breath hitched as his cock sprang free, defying every expectation and sending a wave of panic and disbelief crashing over me.

I couldn’t stand such a taboo. The sheer audacity of him standing there, completely exposed as if this was his right. As if exposing me to something this sinful was right

I swallowed a dry lump in my throat as the sides of my eyes stung with tears of embarrassment.

I had seen naked men on adult websites… But this…? What was seeing in front of me should be considered illegal and dangerous,

I shouldn’t be looking at my brother’s cock, but it was as if my mind was trying so hard to imprint the monstrous size of his cock into my memory.

His body was the epitome of power and control. The harsh nes of his muscles looked as though they had been sculpted by an artist obsessed with perfection. His chest, broad and carved, rose and fell with steady breaths that contrasted my erratic gasps.

He took slow steps toward me, and my mouth moved faster than my brain could, “If… If you come any closer, I’ll… I’ll scream,” I tried to threaten, but I sounded as pathetic al felt.

His next words knocked the air out of my lungs.

“The only thing you’d use that little mouth of yours for will be to suck my cock,” he gestured at his arousal, which was so hard that it could shatter glass, “Now, Kasmine… Kneel.”

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.”
