Chapter 79

KASMINE.

The devil has a name, and he wasn’t in hell.

His name was Kester, and he was right here, on top of me, making me moán his name between gasps and breathless pleas.

My body wasn’t mine anymore.

Pleasure had stolen it, claimed it, reshaped it into something unrecognizable–something made only for him.

The vibrator inside me was maddening, humming, pulsing, teasing the raw, oversensitive flesh of my clit. My thighs quivered violently, torn between squeezing shut from the unbearable sensation and spreading wider to take more of it.

And then there was his cock.

Heavy, thick, stretching my lips wide as he thrust deep into my mouth, shoving himself into my throat, pushing me past my limits. The veins along his shaft pulsed against my tongue, the head hitting the back of my throat with his ruthless push.

My jaw ached, and my throat burned, but I took him, swallowed him, and let him use my mouth however he pleased.

My vision blurred as his fingers clamped down on my nose.

A shock of panic slammed through me.

I gagged, my throat tightening around his length, desperate for air. My eyes watered instantly, hot tears rolling down the sides of my face.

And just when I thought I’d pass out, he let go. Air flooded my lungs, making my chest heave and my whole body shudder.

Kester watched me with a wicked grin spread across his face. His green eyes, which had turned dark, were locked on mine with hunger.

“You look so pretty when you cry for me,” he murmured. His thumb caught a tear trailing down my cheek, smearing it over my lips. “So sweet… so obedient…”

Every so often, he pushed his fingers into my pussy, applying more pressure before pulling out and allowing the vibrator to do its job.

A vein popped on his forehead–the same one that always did when he fucked me like this. When he was too far gone, lost in the need to ruin me.

His hips slammed against my face, his thick, muscular body caging my smaller frame beneath him, dominating me in every way.

The vibrator sent another sharp jolt of pleasure through me. I felt my stomach coiling tight, my walls clenching, and my release right there-

But he knew.

Of course, he knew.

The second he felt my body tightening, he yanked himself from my mouth, leaving me coughing, my lips swollen,

and drool dripping down my chin. His cock stood thick and flushed, gleaming with my saliva and a bead of precum at the tip.

I barely had time to breathe before he grabbed my legs, pushing them back and exposing me completely.

A whimper escaped me.

“Kester…”

His gaze darkened. “Mine.”

He dipped his fingers into my pussy and pulled out the vibrator.

And then he was inside me.

A moan tore from my lips, my head falling back as he drove himself deep into my soaked, pulsing pussy.

I sobbed, my hands balling into weak fists above my head.

Kester wasn’t just fucking me.

He was wrecking me.

His cock slammed into me mercilessly, every thrust spearing me open and sending sparks of unbearable pleasure up my spine. The force of it rocked my entire body, the wet slap of our flesh filling the large room.

“Fuck-” he gritted, “Baby…” He whispered.

He pulled back slightly, then slammed forward again, harder this time, wrenching a sharp cry from my lips.

I couldn’t take it.

I could barely breathe. My body wasn’t my own anymore–it was his, his to use, his to ruin. He fucked me until I was raw and sore, until my body ached with a pleasure so intense it bordered on pain.

And he was ruining me.

With a deep growl, he shifted his grip on my thighs, forcing them even wider.

I gasped.

No.

He had never spread me this wide before.

And then-

“Oh god-!” A scream ripped from my throat as he buried himself deeper, hitting a spot inside me that sent my entire body convulsing.

I tried to close my legs to escape the overwhelming sensation, but he held me open, held me still, with a bruising grip. “Stay open for me,” he ordered, “Let me ruin you.”

I could feel his balls slapping at my entrance. He had buried his whole length inside me.

“Shbb,” he hushed, his palm suddenly covering my mouth, muffling my cries. “Take it, baby,” he growled.

And just when I thought it couldn’t get any more overwhelming-

He reached for something – a clit vibrator.

My stomach flipped.

“Kester-

He didn’t listen. A smirk curved his lips. I wasn’t sure I’d be able to withstand the pleasure. I might pass out.

He pressed the vibrating head directly to my clit, and my body reacted immediately.

Pleasure shot through me like lightning, so sharp and sudden it was almost unbearable. My legs jerked violently, trying to close or to get away, but he wouldn’t let me. His free hand locked onto my thigh, pinning me open as the vibrations pulsed against my clit.

“No, no, no–too much–Kester, please!” I sobbed, yanking at the chains, desperate to escape the overwhelming sensation. “It’s too much-!”

But he only laughed.

“Too much?” His voice dripped with amusement and raw hunger. His thick cock plunged into me over and over, stretching me wide, fucking me deeper than I ever thought possible.

“But you’re taking it so well,” he praised, his breath hot against my cheek. “Look at you, Kasmine, Totally ruined.

I shook my head, tears spilling down my face, my body thrashing beneath him. I couldn’t do this–I couldn’t handle this.

But Kester didn’t care.

He threw his head back, his strong neck flexing, a groan tearing from his throat as he devoured the sight of me. The way my back arched. The way my walls clenched around him, struggling to accommodate his ruthless pace. The way my legs trembled as the vibrations wrecked me and forced pleasure upon me so intense it blurred the edges of my sanity.

“You look so perfect like this,” he groaned, tightening his grip on my thigh. “So open, so helpless… so mine.”

I shattered.

All the pressure that had been building for too long coiled tighter and tighter until my body couldn’t hold it back any longer. The vibrations against my clit pushed me over the edge, dragging me into an abyss of mind–shattering pleasure.

I screamed.

My body jerked and seized-

And then I exploded.

A rush of warm liquid gushed from me uncontrollably, soaking both of us and dripping onto the sheets in a hot, pulsing wave.

Kester froze.

His eyes were blown wide, watching me fall apart beneath him as he felt the liquid dripping down his length.

“Kester… What… What just happened?” My voice broke with the force of his thrusts. I was worried. Did I just pee on the bed?

Something in him snapped.

His grip on my thigh tightened brutally, his thrusts growing wild and desperate, the sounds of our slick privates meeting filling the room.

“Good girl,” he rasped, voice filled with pride and possession. “You squirted for me, Kasmine. You belong to me, baby.”

My vision exploded with white–hot light, my body spasming uncontrollably as wave after wave of unbearable pleasure consumed me.

But he didn’t stop.

Not yet.

The vibrator still pulsed against my oversensitive clit, sending sharp aftershocks through my trembling frame. Kester’s thrusts grew erratic and desperate, his breath ragged as he chased his own release. His fingers dug into my flesh, holding me down and forcing me to take everything he gave me.

“Mine,” he growled again, his voice thick, broken and raw. All of you. Only me.”

A second later, he tensed-

And with a deep, guttural groan, he snapped.

His cock pulsed forcefully inside me, heat flooding my core as he spilled into me, his release mixing with mine, making his body shake from the force of it.

And then-

Something happened.

Something that had never happened before.

As the last waves of pleasure wracked through me, my vision cleared just enough to focus on him…

I saw it.

A single tear.

Sliding down the sharp edge of his cheek.

My breath hitched.

Kester never cried.

Never showed weakness.

But for the first time, I saw his weakness-

The raw, unfiltered emotion beneath his dominance. The depth of what he felt and what this meant to him.

And it made my heart ache.

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.”
