The Professor's Pet-6

SOPHIA

My fingers trembled as I scrolled through the folder on my phone. The first photo was me — two years ago, sitting in a campus coffee shop, laughing with friends, completely unaware I was being watched. Before our parents ever met. Before Cain Hilton became my stepbrother.

He had been stalking me. Planning this.

Horror and a sick, twisted thrill warred inside my chest. I was still naked, the heavy collar locked around my throat, his cum from last night dried on my thighs. Cain slept soundly beside me, his powerful body relaxed, cock soft but still intimidating against his thigh.

This was my chance.

I slipped out of bed silently, grabbed my clothes from the floor, and crept toward the door. My heart pounded so hard I could hear it in my ears. The cabin door creaked as I opened it. Cold night air hit my bare skin.

I ran.

Barefoot, half-dressed, phone clutched in my hand, I sprinted into the dark woods. Branches whipped at my arms and legs. The collar bounced against my collarbone with every step. I didn’t know where I was going — just away from him. Away from the man who had ruined me so perfectly.

Headlights suddenly cut through the trees behind me. His truck.

“Sophia!” His voice roared through the night, dark and furious. “You can’t run from me, little sister. Your cunt already knows who it belongs to.”

I pushed harder, lungs burning, but he was faster. Strong arms caught me from behind, slamming me against a thick tree trunk. My breasts pressed into the rough bark, nipples scraping painfully as he pinned me there.

“You looked at the folder,” he growled into my ear, one hand yanking my skirt up while the other held my wrists above my head. “Bad pet.”

I whimpered as his fingers found my pussy — already wet again, traitor that it was. Two thick fingers plunged inside me without warning, curling hard against my g-spot. I moaned loudly, hips bucking back despite myself.

“Still so fucking soaked for your stepbrother,” he snarled. He shoved my panties aside completely and freed his cock. It was rock-hard again, the thick veined length slapping against my ass.

He didn’t tease this time.

Cain lined up and thrust into me in one savage stroke, burying every inch deep into my dripping cunt. I cried out, the sound echoing through the woods. He was so big, stretching me wide, the head of his cock battering my cervix with brutal force.

“Fuck… Cain!” My walls clenched greedily around him as he started pounding me against the tree. Each powerful thrust lifted me onto my toes. My breasts scraped against the bark with every slam, sending sharp sparks of pain-pleasure through me. His heavy balls slapped rhythmically against my clit.

He fucked me like an animal — raw, unforgiving, hips snapping forward with punishing speed. One hand left my wrists to grip my collar, using it like a leash to pull me back onto his cock. The other reached around to rub my swollen clit in fast, rough circles.

“You think you can run?” he grunted, biting down on my shoulder hard enough to mark me. “This pussy milks me every single time. You were made for your big brother’s cock.”

I was losing control. The fear, the discovery, the raw dominance — it all mixed into a firestorm. My juices squirted around his pistoning shaft with every deep thrust, coating his balls and dripping down my legs. My nipples were raw against the tree. The collar dug into my throat as he pulled it tighter.

“I’m going to come,” I gasped, voice breaking.

“Not until you admit it,” he growled, slowing his thrusts to deep, grinding rolls that rubbed every inch of my sensitive walls. “Admit you’ve wanted this since before you knew I existed.”

“I… I can’t…” But my hips pushed back, fucking myself on his thick cock.

He slapped my clit hard. Once. Twice. Then slammed into me faster.

I shattered.

My orgasm exploded violently. My pussy spasmed and squeezed around his cock like a fist, waves of intense pleasure ripping through my body. I screamed his name into the night, squirting hard down my thighs as my legs gave out. Only his cock and the tree kept me upright.

Cain roared and buried himself to the hilt. His cock swelled, then pulsed as he came deep inside me. Thick, hot ropes of cum flooded my womb, filling me until it leaked out around his shaft with every shallow thrust. He kept grinding through his orgasm, making sure every drop stayed inside his stepsister’s cunt.

He pulled out slowly, his cum dripping down my legs. Then he spun me around, pressed my back to the tree, and dropped to his knees. His mouth attacked my oversensitive pussy — licking, sucking, devouring his own cum mixed with my juices. His tongue fucked into my hole while his nose rubbed my clit.

I came again on his face, weaker but no less shattering, my hands fisting his hair as I rode his tongue.

Only then did he stand, lift me into his arms, and carry me back toward the cabin.

“You’re never leaving me,” he whispered against my hair as we crossed the threshold. “And there’s one more secret you need to know.”

He laid me on the bed and opened his laptop. On the screen was a video call already connecting.

My mother appeared — but she wasn’t alone. Cain’s father sat beside her, both of them smiling knowingly at the camera.

“Hi sweetheart,” Mom said softly. “We’ve known about you and Cain for a while now. We… encouraged it.”

My world tilted.

They had arranged everything.

My own parents had set me up to become my stepbrother’s personal fucktoy and project? How deep did this twisted family conspiracy go… and what sick new games did they have planned for me now that I knew the truth?
