Chapter 306

KASMINE.

His hand closed around my throat again, “Up,” he ordered. “Now.”

My legs nearly gave out beneath me when I tried to obey, but he caught me easily, lifting me from the bath like I weighed nothing. Water cascaded off me in rivulets, steaming against the chill of the bathroom.

He didn’t give me a towel. He didn’t even let me clean myself.

He wanted me dripping, exposed, and shaking.

He walked me across the marble floor, with his hand firm between my shoulder blades, leading me to the full–length mirror and stopping me right in front of it.

Steam clung to the glass in curls, but he wiped a path down the center with the flat of his palm, revealing my reflection–wet, flushed, and wrecked.

My nipples were tight peaks, my mouth slightly parted, and my hair a tangled mess over my shoulders.

I looked obscene. Beautifully obscene.

“Hands on the counter.” He commanded in a voice so rich it made my center quake again.

I hesitated–and that earned me a sharp smack to the back of the thigh.

“Now, Kasmine.”

I obeyed, pressing my palms flat against the cold marble.

“Look straight ahead. Don’t close your eyes.”

I felt him behind me.

His bare chest pressed against my soaked back, and he reached down to shove my thighs apart with his knee.

“This is how I want you,” he whispered, “Open. Quiet. Staring at yourself while I ruin you all over again.”

He didn’t touch my entrance first. No. His fingers trailed up the insides of my thighs, spreading me further apart. His bedy hovered just behind mine, radiating heat like a furnace.

“See that?” he murmured near my ear. “That girl in the mirror? Thats what you look like when you’re mine.”

Then, his two fingers pushed inside. Deep… So deep, I gasped out loud.

My hips bucked, my eyes snapping wide at the sight of him behind me. He was so tall, broad, and dangerous. around my waist to hold me in place while the other pumped into me from behind.

It was… unspeakably filthy.

e arm wrapped

His fingers curled expertly, dragging across that devastating spot again and again, the angle cruel, punishing. My knees buckled, but he held me up with a growl, his hand flexing against my belly.

“Don’t run,” he rasped. “Take it. Watch yourself take it.”

The image in the mirror stole the breath from my lungs. The way his forearm looked braced across me, how my breasts jostled as his fingers thrust into me, how lushed and desperate I looked–how good he looked using me.

“Look how wet you are,” he hissed. “Dripping down my hand.”

I couldn’t tear my eyes away from the mirror. The reflection was its own kind of filth.

Kester was a vision of restraint breaking apart. His jaw was clenched, the tendons in his forearms tight as rope, his chest rising and falling in barely contained lust and desire. His eyes were fixed on mine in the mirror, and they were black with hunger.

He looked dangerous.

His mouth dropped to my ear again, his voice sounding like gravel and sin. “Say my name.”

I froze. My lips quivered. His fingers slowed… just enough to make me ache.

“Say it, Kasmine.” His tone was darker now, almost reverent as if the words from my mouth would be holy.

And I broke.

“Please… Kester,” I begged, not sure what I was begging for.

“Again,” he ordered again, the tip of his tongue flicking the shell of my ear.

“Kes…” I whispered, then louder, “Kester….!”

He growled.

I caught his eyes in the mirror and gasped.

His lips were parted. His pupils were blown wide. His cock was rock–hard against the seam of my ass, and it was twitching, heavy, and aching to be buried. He was close to snapping. I saw it.

His control was splintering.

And it turned me on even more.

“Come for me, baby,” he hissed.

That was all it took.

I shattered, and I came hard around his fingers, my muscles clenching as I collapsed forward against the vanity.

***

KESTER.

I had planned to carry her to the bed. That had been my only thought as we left the bathroom.

I wasn’t sure she’d be okay with me fucking her tonight.

She was breathless, and her body was trembling from the multiple releases I gave her. She needed to rest and sleep.

I might just jerk off using my hands when I put her to sleep because my cock was still pulsing with the kind of urgency that bordered on pain.

She was soft in my arms, pliant and spent. But to my surprise, when turned us toward the bed, her hand slid down my chest and stopped me.

Then she gestured to the chair by my vanity.

I raised a brow. “The bed’s right-”

She didn’t let me finish.

She dropped down from my arms and stepped ahead, water still glistening on her skin. Her hips swayed as she moved to the chair. Then she turned, met my eyes with a glint I hadn’t seen before–and pulled me by the wrist.

Without a word, she guided me down into the chair.

I was still naked and still burning for her.

She slowly placed my hands on the armrests. The muscles in my forearms flexed, instinctively resisting. What was she doing?

“Mine,” I murmured, “What is this?”

She only smiled. And fuck, that smile looked sinful.

Then she walked to the closet.

I tilted my head, curious, “Baby?”

She returned holding two of her lingerie pieces.

She leaned in with her face so close to mine that her breath feathered over my jaw as she began to tie one of the flimsy straps around my right wrist, looping it tightly around the armrest, then securing the knot with a pull that told me she’d thought about

this.

“Kasmine…” I warned, but she only hummed in response.

Then, she did the Jame to my left wrist. My both arms were spread out, and my hands were tied down. My chest rose with a shallow breath as the realization of what she was doing settled in.

I wasn’t in control anymore.

She knelt between my legs.

Her lips, soft as silk, brushed my inner thigh, and then she whispered, “You punished me in the bathroom. Her breath ghosted over the head of my cock. “Now I’m going to return the favor.”

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.
