Chapter 81 

KASMINE

The phone dangled between Kester’s fingers; the screen began to glow with the same name flashing persistently. Jake

The way he held the phone, the way his jaw ticked beneath the dim sunset glow, the way his body coiled like a beast seconds away from strikingI knew I was in trouble

Kester was a possessive man. Territorial to the point of madness. I had never tested his patience like this before. I’d danced around the edges of it, teased him with it, but now? Now, I had shoved a blade straight into the gut of his control

Where did you get that?My voice came out hoarse, almost pathetic

His lips twitched, but there was no amusement in his eyes. Only something terrifyingly dark. Something sharp enough to cut. Where do you think, baby?” 

I swallowed hard

I had hidden it well. Or at least, I thought I had

Kester hummed, tilting his head and running a thumb over the screen. Funny thing about secrets, Mine,he murmured. They don’t stay buried for long.” 

Then, right before my eyes, he turned and flung the phone into the water below

Gone.. 

I gasped, my pulse spiking, my body jerking forward instinctively like I could somehow retrieve it, but Kester was faster. His arm wrapped around my waist, dragging me back against his chest and forcing me to feel every ripple of muscle and every ounce of heat burning through his skin 

He dipped his head, his lips brushing the shell of my ear. I haven’t killed him, you know” 

My heart stopped

He’s just a boy,Kester continued, his voice so low and terrifying in its softness. A small, fucking boy who doesn’t even know what to do with a woman like you.He exhaled slowly, his fingers gripping my hips. And because his late mother was once friends with mine, I let him breathe.” 

I trembled, my nails digging into the railing. Kester-” 

But you,he cut me off, his teeth grazing my ear. You’re pushing me too hard, baby.” 

He turned me in his arms so fast my breath hitched, his dark, bottomless eyes pinning me

You keep testing me,he rasped, his thumb dragging along my throat. Keep tempting me to be the man you know I can be.His hand slipped lower, curling around my waist. Do you want me to snap?” 

I whimpered, my knees locking together as his fingers slid up my thigh, under my dress, his knuckles brushing the heat between my legs

Tell me, Kasmine.His breath was a ghost against my lips, his body caging me in, owning me, consuming me. Do you want me to remind you why no one else can have you?” 

I hated how easily I melted for him

How my body surrendered before my mind could even protest

I should have been angry. I should have fought back. But instead, I ached

His eyes dropped to my mouth, and in one swift move, he crushed his lips against mine

It wasn’t a kiss

It was destruction

He swallowed my gasp, his hand fisting my hair as he kissed me like he wanted to mark me from the inside out. His tongue thrust into my mouth, demanding, taking, owning

I moaned into him, my body arching, my hands clutching at his arms

You’re shaking,he murmured, his breath hot against my ear. Is it fearor pleasure?” 

A pulse of heat shot through me, and I whimpered as his hand wrapped around my throat, forcing me to meet his 

gaze

You will never fucking lie to me again,he growled. Do you hear me?” 

I nodded breathlessly

His grip tightened, Say it.– 

II won’t lie to you,I choked out

A dark smirk touched his lips. Good girl.” 

Then he yanked my dress down, baring me to the cool evening air, to him

Before I could even catch my breath, his mouth was on me again. His tongue lashed over my nipple, his teeth scraping just hard enough to make me gasp

My head fell back, my hands digging into his hair as he moved lower, trailing wet kisses down my stomach, his fingers slipping beneath the waistband of my panties

Let me remind you, baby.He hooked the fabric, dragging it down my legs slowly, Let me remind you who you fucking belong to.” 

He turned me harshly, pressing my back against him, my bare stomach leaning against the railing

The height beneath me was dizzyingjust one slip, and I’d be swallowed by the water and darkness beneath us

But the risk made it intoxicating

The way he easily pulled down his pants and freed his length made me shudder. And then, the next moment, he pushed inside my sore pussy. A yelp escaped my lips at the suddenness

My body arched beneath him with a mixture of pain and pleasure, fear and desire, when he began to thrust into 

  1. me

He gripped my hips tightly, pulling me closer to him to give him a better angle for a deeper penetration

AhhKesterPleaseI cried as he pushed me to the edge

He moved his hand to my throat, his thumb rubbing against my pulse as he spoke, You are mine. Only mine. Do you understand?his voice was dark and dangerous. I nodded, my breath coming in ragged gasps. Don’t make me kill anyone else because of you.” 

My brain was too busy to even proceed what he had just said. I just nodded blindly, moaning like a slut

Don’t just stand there. Fucking fuck me back!He rasped, smacking my bare ass, making me to yelp. I obeyed, moving my hips and waist to match his thrusts

As he thrust deeper, I noticed a section of the railing, a splintered piece of wood, looking increasingly fragile. The force of his punishing thrusts was making it crack and splitter even more

I tried to move, but his hand held my waist firmly, keeping ne right in place

My stomach clenched

Kester- 

His hand shot up to my throat, fingers curling around it, cutting off my words before they could spill

Not a word.He warned, his voice dripping with so much control it made my skin burn. Just take it.” 

A whimper caught in my throat as he drove into me harder, with each thrust rocking me forward, pushing me toward the very edge I was trying to avoid

Panic licked at the edges of my pleasure. The railing wasn’t built for this. I gripped the wood, my nails biting into the smooth surface, but it only seemed to worsen the break. If he didn’t stopif he kept driving into me with this recklessness, one particularly hard thrust, the rail might give way entirely

Kester, the railI managed, but his fingers dug into the skin of my throat

I said take it,He gritted his teeth

My heart slammed against my ribs. Every inch of my body screamed for survival, but another, deeper part of me- one far more dangerousthrived in the threat

Kester’s grip on my throat tightened. You love it, don’t you?” 

I did. Goddess help me, I did

The fear. The pleasure. The way his cock kept me tethered even as the world beneath us threatened to crumble

Suddenly, the rail gave a sickening lurch. My body jolted forward, only to be wrenched back by Kester’s grip. He growled low in his throat, dragging me against him

Stay with me,he commanded, his breath ragged against my ear. I’ve got you.” 

But did he? The rail screamed beneath us, giving another warning that it couldn’t take much more

Then- 

No, no no- 

A final snap

The rail shifted

I gasped, but Kester was faster. His arms locked around my waist, yanking me against his chest just as the wood beneath us creaked its last protest

A second later, he was inside me againholding me up, with his arm wrapped across my neck, fucking me through the chaos like nothing had just happened

His other hand, which held my hips, began to slide up and down my clit, drawing out what remnant of pleasure 

there was

His other hand wrapped around my throat again, pulling my head up to meet his towering gaze from behind me. He smirked when he saw the tear that escaped my eyes

All I could do was whimper at that point and pray my body could go on much longer

Kester pulled out of me with a wet sound, his muscles still tense from holding me upright

He made me face him and lifted me effortlessly, my legs wrapping around his waist on instinct, my slick heat rubbing against the hardness of his abdomen

He didn’t give me a moment to recover. His mouth latched onto my breast, and his hot, wet tongue swirled around the stiff peak before he bit down just enough to make me gasp

Kester-” 

A sharp slap landed on my ass, the sting rippling through my body, sending a fresh wave of heat between my thighs

Shh, baby,he husked against my skin. He licked over the spot where his teeth had just been, soothing the burn before delivering another firm spank. Fuck. I want to own every fucking part of you.” 

I whimpered, my fingers diving into his hair, tugging him closer. He walked us inside. The dim glow of the room highlighted the hunger in his gaze as he carried me toward the couch

I barely had time to process before he dropped onto the couch with me straddling his lap

But he didn’t move

Instead, he just looked at me. I was a panting mess

His dark eyes roamed over my face, drinking me in like I was the only thing keeping him breathing

I swallowed as I stared back at him, wondering what was going on in his mind. His intense stare always made my cheeks burn. I would never get used to Kester’s intense stare. It did things to me that I was so ashamed to admit

He sucked in air and placed his forehead against mine briefly before pulling away and gazing into my eyes

Then, so softly I almost didn’t hear it, he whispered, I love you.” 

My lungs constricted, and I suddenly forgot how to speak

Gods. The tenderness in his eyes was a discovery

His fingers tightened on my hips, his jaw flexing as he closed his eyes for a brief moment before opening them again. I fucking love you, Kasmine.” 

I parted my lips, but nothing came out

His eyes darkened, searching mine for an answer

Say it back,he murmured, almost pleading. Tell me you love me, baby.” 

I froze

His fingers twitched against my skin, his brows furrowing ever so slightly. You’ve never said it before.His voice was quieter now, Not once.” 

I shook my head slowly, not able to break his gaze

His breathing changed

Kasmine” 

My lips parted, but I still couldn’t say it. I couldn’t let those words slip free

Because saying them would mean accepting everything Kester was. Everything he had done. Everything he would do for me. And everything we were not meant to be

Those words would sign my fate

He exhaled harshly, his fingers sliding up my back, tangling in my hair. Say it.” 

I swallowed and shook my head

His jaw clenched, his grip tightening. His control was slipping, that dangerous edge creeping back into his voice.Say it, baby. Just once.” 

II can’t, KesI whispered, moisture gathering in my eyes at the raw emotion I saw in his eyes

His eyes flashed with something dark that I feared. Kasmine-His voice broke along with my heart. Please.I just stared at him before doing the one thing I knew would drive him mad

I leaned in and kissed himsoft, slow, and deeppouring everything I felt into it and wishing he’d feel it too

But he pulled back just an inch. His hand wrapped around my throat while his eyes burned into mine. You will say it, Kasmine,he vowed, Even if I have to fucking break you to hear it. One day, you will.” 

And I knew that he meant every word he just said

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.”
