The Professor's Pet-7

SOPHIA

The laptop screen glowed in the dim cabin light, my mother’s face smiling at me with a warmth that now felt utterly perverse. Cain’s father — my stepfather — sat beside her, his hand resting casually on her thigh. They looked… proud.

“Sweetheart, don’t look so shocked,” Mom said softly, her voice carrying that same gentle tone she used when I was a child. “We saw how you looked at Cain from the very first family dinner. We knew you needed someone strong enough to handle you. To *own* you.”

Cain stood behind me, his hands on my shoulders, thumbs stroking the edge of the collar around my throat. His cum was still leaking down my inner thighs from the brutal fucking against the tree. I was naked, marked, trembling — and my pussy clenched at their words despite the horror flooding my veins.

“You… arranged this?” I whispered, voice cracking.

Cain’s father chuckled. “Your mother and I have certain tastes. Cain inherited them. Consider this your family legacy, Sophia.”

The call ended with a promise to “check in later.” The screen went black.

I spun around, but Cain was already on me. He shoved me back onto the bed, climbing over me like a predator. His gray eyes burned with fresh hunger now that the last secret was exposed.

“You belong to all of us now,” he growled, pinning my wrists above my head with one hand while his other shoved my legs apart. “But this cunt is mine first.”

His thick cock was rock-hard again, the veined shaft still slick with our combined juices. He rubbed the fat, leaking head up and down my swollen, cum-soaked folds, teasing my clit until I whimpered and tried to arch into him.

“Cain… this is insane,” I gasped, even as my hips rolled greedily, begging for him.

“Insane is how wet you get knowing your own family set you up to be my personal fucktoy.” He pushed the head inside me, stretching my entrance, then stopped. “Feel that? Your pussy is sucking me in. It knows the truth.”

He slammed home in one devastating thrust. I cried out, back bowing off the bed as his cock filled me completely, the head battering my cervix. He fucked me with slow, deep, punishing strokes — pulling out until only the tip remained, then driving back in until his heavy balls slapped against my ass.

Every thrust made my full breasts bounce. He leaned down and captured one nipple between his teeth, biting and sucking hard while his hips rolled in filthy circles, grinding against my clit. My walls fluttered and clenched around his thick length, milking him desperately.

“Fuck… you’re so deep,” I moaned, legs wrapping around his waist, pulling him even closer. The collar shifted against my throat with every powerful snap of his hips. Pleasure and shame twisted together until I couldn’t tell them apart.

He released my wrists and grabbed my hips, angling me so he hit that perfect spot inside me with every stroke. Wet, obscene squelching sounds filled the cabin as he pounded my dripping cunt faster. My juices mixed with his earlier load, frothing around his pistoning cock and soaking the sheets.

“Look at me,” he commanded.

Our eyes locked. His face was dark with possession.

“You’re going to come while I tell you what happens next,” he grunted, never slowing. “Tomorrow, you’re signing the papers. Then you’re moving into my house permanently. No more thesis. No more pretending. You’ll be my collared pet — available whenever I want this tight little stepsister pussy.”

His words should have terrified me. Instead, they sent a fresh gush of arousal around his cock. He reached between us and rubbed my swollen clit in tight, fast circles.

“I can’t… oh god, Cain—”

“Come,” he snarled, slamming into me harder. “Come knowing your parents are proud of what a good little whore you are for me.”

The orgasm hit like a freight train. My pussy spasmed violently around his thick cock, squeezing and rippling as waves of blinding pleasure tore through me. I screamed, nails digging into his back, squirting hard around him as my thighs shook uncontrollably. He fucked me straight through it, prolonging the ecstasy until I was sobbing and oversensitive.

Only then did he pull out, flip me onto all fours, and mount me from behind like a beast. He gripped the back of my collar like reins and drove back inside my fluttering cunt in one brutal stroke. The new angle let him go impossibly deeper. His hips slapped against my ass with loud, wet smacks as he railed me mercilessly.

“Take it,” he growled, one hand reaching around to pinch and tug my nipples while the other rubbed my clit again. “Take your stepbrother’s cock like the family fuckpet you were born to be.”

I came again within minutes, collapsing forward as my arms gave out, face pressed into the mattress while my pussy continued convulsing around him. Cain roared, burying himself to the hilt. His cock swelled and erupted, flooding my womb with thick, hot jets of cum. Pulse after pulse, so much it overflowed and ran down my thighs in creamy rivers.

He stayed buried deep, grinding slowly as he caught his breath, then leaned over me.

“There’s one more thing,” he whispered against my ear, voice dark with promise. “Your mother wants to watch next time.”

My eyes widened in fresh shock.

Before I could respond, his phone buzzed on the nightstand. A text from an unknown number lit up the screen.

Unknown: She’s ready for the next phase. Bring her to the house this weekend. The whole family will be there.

What did “the whole family” mean? And how much further would they push my body and mind in their twisted game now that I was truly trapped?

The weekend at the family estate was inevitable. Cain drove me there collared, plugged, and dripping—his cum from the morning still leaking into the expensive leather seat. My mother and stepfather greeted us at the door like this was a normal family reunion. Their eyes lingered on my short dress and the visible bulge of the plug in my ass.

“Welcome home, pet,” Mom said softly, kissing my cheek while her hand brushed over my breast. “We’re so proud of how well you’ve taken to your training.”

The living room had been prepared. Candles. A large padded bench in the center. Cameras set up.

Cain stripped me slowly in front of them. My dress pooled at my feet, leaving me naked except for the collar and the jeweled plug stretching my ass. My nipples were hard, my pussy already glistening with shame and need.

“On the bench,” Cain commanded.

I obeyed, lying on my back, legs spread wide in the stirrups they had attached. My stepfather approached first, older but still powerful, his cock thick and heavy as he pulled it out.

“Your mother wants to see how well you serve the family,” he said, sliding his cock into my mouth while Cain positioned himself between my legs.

Cain yanked the plug out and replaced it with his own massive cock, thrusting deep into my ass in one smooth stroke. I moaned around my stepfather’s shaft as they filled both my holes. The stretch was overwhelming—burning pleasure that made my eyes water.

They fucked me in perfect rhythm. Cain pounding my ass with deep, brutal strokes while my stepfather fucked my throat. Mom watched from the side, fingers buried in her own pussy, moaning softly.

“Such a good girl,” she whispered. “Taking your stepbrother and stepfather so beautifully.”

The sensations were too much. Cain’s thick cock reaming my ass, rubbing against the thin wall separating him from my stepfather’s cock in my throat. My clit throbbed untouched. I came hard, screaming around the cock in my mouth, my holes clenching and spasming.

They didn’t stop.

Cain pulled out of my ass and drove into my pussy, fucking me with savage strokes while my stepfather moved behind him. I felt the older man’s cock press against Cain’s, both of them stretching my cunt at the same time. Double penetration. The fullness was insane. I screamed in pleasure-pain as they worked together, stretching my walls to their limit, their cocks rubbing against each other inside me.

“Fuck… I’m going to break,” I sobbed, but my hips bucked desperately for more.

Mom climbed onto the bench and straddled my face, lowering her wet pussy onto my mouth. “Lick Mommy while your men ruin you, sweetheart.”

I obeyed, tongue fucking my own mother while Cain and his father destroyed my cunt. The obscene sounds—wet slapping, moaning, the squelch of two cocks in my stretched hole—filled the room.

Cain rubbed my clit furiously. “Come for your family, little sister. Show them who owns this body.”

I exploded. My orgasm was cataclysmic. My pussy convulsed violently around the two cocks, squirting hard around them as wave after wave of blinding pleasure tore through me. My mother came on my face, grinding down as she cried out.

The men followed. First my stepfather, flooding my womb with hot cum. Then Cain, roaring as he pumped rope after rope deep inside me, mixing with his father’s seed until it overflowed and ran down my ass.

They pulled out slowly, leaving me a trembling, cum-soaked mess.

Cain leaned over me, kissing me deeply, tasting my mother on my lips.

“You’re ours now,” he whispered. “Completely.”
