Chapter 51

Book:Mated To My Obsessive Stepbrother Published:2025-3-21

KASMINE.
“Kester, no! You can’t do this.” My voice trembled, but it barely left my lips before he had me. His grip was firm, almost punishing, as he yanked me toward him by my ankle. I gasped when I felt the weight of him press down on me, the heat of his body sinking into mine, and the realization of how much trouble I had gotten into came hitting me hard.
“You’re my brother,” I rasped, fingers curling against his chest as if I could push him away. “This was never meant to go this far. Please, Kester-”
But reason had long left his eyes.
Desperation surged through me. I cupped his face in my shaking hands, forcing him to look at me. “I’m your sister. This is wrong, Kes…” I whispered, pleading, searching for a glimmer of restraint in those smoldering, ravenous eyes.
Never-never in my wildest fantasies did I imagine giving my virginity to my stepbrother. I knew I had fantasized a whole lot of other things, but this? Sticking his dick into my vagina? Him claiming what had never belonged to anyone? It terrified me.
His eyes were molten with desire. His large hand slid down to my waist, fingers digging in possessively, holding me in place as his mouth crashed over mine, devouring, burning. I whimpered against his lips, torn between resistance and surrender. He kissed me like a man starved, his tongue plunging past my lips, dominating, demanding. The taste of him was sinful-raw heat and frustration tangled into one fevered assault.
He kissed fiercely with all the pent-up anger he’d been harboring all night.
He tilted my head with his fingers tangled in my hair, plundering into my mouth and dominating me as always. A treacherous moan escaped my throat before I could stop it.
I pressed against his chest, my mind screaming at me to push him off, to end this before it spiraled beyond return. But the fire in his touch had already begun its slow, agonizing burn inside me.
“Kester…” My breath hitched between kisses, my protest drowning in the way he swallowed my words, my willpower crumbling with every stroke of his tongue fucking my mouth. “This… is… wrong…”
My center betrayed me, weeping for attention.
Heat pooled low in my belly, spreading between my thighs in a shameful, aching need.
“Who made it wrong, hm?” he murmured as he rolled his hips, pressing his hard arousal against my pulsing innocence. “Tell me, Mine-was it wrong when you let me touch you last time? When you moaned my name while you touched yourself the other day?”
He reached down and found my nipple, rolling it roughly between his fingers. Another moan betrayed me as a new wave of pleasure erupted through me.
Heat licked through my veins, my thighs clenching involuntarily as my core ached for him. Shame colored my face, but I quickly looked away.
His breath was heavy, and his voice was thick with a dangerous obsession. His fingers slipped lower, pressing against my drenched folds, “Fuck… you’re soaking wet for me. Did Jake also make you this wet?” He asked, and my stomach dropped, but before I could dwell on the thought, he pressed his hardness against my entrance, forcing a sharp cry from my lips.
“You’re also perfectly shaved,” he hummed, “Was this also for that bastard?” I ignored him. Of course, it wasn’t. I kept down there shaved all the time. I liked it that way.
I looked up at his lustful eyes, “Do you know what it means if you take my virginity? This will never end well. It can’t be, please,” I tried to reason with him.
A chuckle rumbled in his chest, “I know damn well what it means, Mine.” He pulled closer, leaning ever so close, “It means any other man who touches you will die by my hands.”
“You are insane! You are… You need help!” I yelled at him from the instant fear his words put in me, pounding on his chest and struggling out of his grip, but his hand shot out and held both my hands securely in his large one, pinning them above my head.
“You can scream all you want. June isn’t home,” He announced, and for a heartbeat, I feared. Even if I didn’t want this, there was no one to help me, no matter how hard I decided to cry and yell.
“You betrayed me, Mine… Can I ever forgive you for that?” He rested his forehead against mine, panting with his eyes closed, “You pushed me too far…” His lips ghosted over mine, a shuddered breath escaping him. “And now… now I can’t control my actions anymore.” he sounded regretful.
I didn’t know what he meant. His words scared me.
“Kester… I’m sorry. I was…” The words died in my throat. I had so many excuses for what I had done. But none of those excuses seemed enough to heal the level of brokenness Kester was displaying. It scared me.
“But it’s okay. I’ll make you mine tonight.” He lifted his head and held my gaze in those intimidating eyes of his, “I’ll fuck you so hard. And I won’t stop until you know that I own you, until you scream my name and know that no one else can make you feel this way. Not even him.”
He gazed right into my eyes as he said those words, and just like a slave answers to their master, my vagina clenched at those cruel words.
His indifference ran down my spine, leaving a trail of goosebumps in their wake.
He held my gaze as he stroked himself, the thick head of his length grazing against the heat of my soaked core. I shuddered, feeling betrayed by my own body.
His body, which was built for sin, made matters worse. The hard ridges of his chest pressing against me, his strong, veiny arms holding me in place, his tan muscles flexing with every move he made… It all formed a recipe of lust and need that I could barely overcome.
He was a true definition of strength and power, dominance and control… And right now, he controlled my body like he built it.
The moral part of me desperately wanted to escape this. But the other side of me… The side, which was already neck-dip in the thrill this sinful god had to offer, kept making my core clench with anticipation.
I whimpered, my hips jerking instinctively, chasing the friction.
“Good… Stop fighting it, Kasmine.” His voice was molten and dangerous. His fingers gripped my thighs, spreading me wider beneath him. “You don’t want to fight this.”
I shook my head as a tear slid down my cheek, “We shouldn’t be doing this… We shouldn’t…” I whispered in resignation, knowing there was nothing else I could do to stop him.
Whatever protest I put up was only going to make things worse for me. There was no point fighting a lost battle.
***
KESTER.
The moment I nestled myself between her thighs, it seemed my anger slowly dissipated. She lay beneath me, naked, fragile, all mine, ready to be devoured by me.
She begged me to stop, but her tears only fed my hunger.
My cock jutted out painfully, and my heavy balls hung below. They were fucking heavy and needing a release. I moved up and down her slit, coating it with her juices, getting it ready.
I had to bury it in her quickly. I had to fuck that tight pussy now. I didn’t know if I’d have the patience to let her adjust to my size before tearing her apart. I was fucking going insane for her.
She twisted from one side to the other, her hands gathering up the soft sheets at her sides into knots, and it seemed her whole body grew pink at the sensation of having my cock just outside her entrance. Her nipples looked as hard as if they were tiny stones. I could not resist them as I leaned in, taking them into my hungry mouth one at a time.
This was more than a dream come true for me. And if I didn’t control myself, I might as well die from happiness.
I kissed her tears, knowing I was the reason they fell. A moan escaped her lips, and I groaned in response.
Her thighs were wide open while my cock grazed her sleek entrance. Fuck. It was the best sensation I’d ever lived to experience.
I could feel how small her pussy was. So innocent. And I wasn’t only going to take her innocence, I wasn’t going to devour it, ruin it.
She swore she hated me, but I could feel her soul begging for me every second.
I pushed forward, letting my painfully hard length circle her clenched vagina again, slowly running it around the edges before fisting it and placing the blunt head against the opening.
“Brace yourself, Mine,” my voice didn’t sound like my own. I was lost in dark desires, “This is going to hurt like hell.”
