The Professor's Pet-5

SOPHIA

My heart hammered so loudly I was sure he could hear it through the wall. Others. The word echoed in my skull like a gunshot. I stood frozen just outside the door, still naked except for the heavy leather collar locked around my throat, his dried cum still sticky between my thighs from earlier.

Cain’s voice continued, low and clinical. “No, this one’s different. Smarter. More resistant. But she’ll break just like the rest. By the end of the semester, she’ll be begging to drop out and serve me full-time. The leverage is ironclad.”

I backed away slowly, but my foot creaked on the old wooden floor.

The call ended instantly. The door swung open.

Cain filled the doorway, shirt unbuttoned, gray eyes glittering with dangerous calm. “Eavesdropping, pet?”

I tried to run, but he was faster. His hand shot out, fingers wrapping around the metal ring on my collar, yanking me forward until my bare breasts slammed against his hard chest.

“You weren’t supposed to hear that,” he murmured, almost tenderly, as his other hand slid down to cup my ass possessively. “But maybe it’s time you learned exactly what you are.”

He dragged me back to the bed and threw me down on my back. Before I could scramble away, he cuffed my wrists to the heavy iron headboard, then spread my legs wide, securing my ankles to the footboard with leather straps. I was completely open, exposed, my swollen pussy still leaking his earlier load.

“Cain… please,” I whispered, fear and twisted arousal warring inside me. “Who were the others?”

He stripped slowly, revealing his sculpted body and that thick, heavy cock already hard again. He climbed between my spread thighs, rubbing the fat head of his cock up and down my slick folds, teasing my clit.

“Curious little slut,” he said darkly. “There were three before you. All brilliant. All mine for a semester. Two dropped out and disappeared. The third…” He pushed just the head inside me, stretching my entrance. “She tried to expose me. I ruined her. No degree. No career. She sends me videos of herself masturbating with my name on her lips every month now.”

I moaned as he sank another inch deeper, my walls fluttering around him despite everything.

“You’re different,” he growled, thrusting all the way in with one powerful stroke. I cried out, back arching off the bed. “You fight it. You hate how much you need your stepbrother’s cock destroying this perfect cunt.”

He started fucking me with long, punishing strokes—pulling almost all the way out, then slamming back in until his balls slapped against my ass. The chains on my cuffs rattled with every brutal thrust. My heavy breasts bounced wildly. He leaned down and sucked one nipple into his mouth, biting hard enough to make me scream.

“Tell me you’re better than them,” he demanded between thrusts, grinding deep. “Tell me this pussy was made for me.”

“I—I’m yours,” I gasped, tears streaming down my face as pleasure built violently. Every drag of his thick cock against my g-spot made me clench. “My stepbrother owns me… fuck… harder!”

He released my nipple with a wet pop and grabbed my hips, pounding me mercilessly. The wet, filthy sounds of his cock destroying my soaked pussy filled the cabin. My juices squirted around him with every deep plunge.

He reached between us and pinched my clit, rubbing it fast. “Come, pet. Come knowing I’ve broken better girls than you.”

The orgasm tore through me like lightning. My pussy spasmed wildly around his pistoning cock, milking him as I squirted hard, soaking his abs and the sheets. I screamed his name until my throat went raw, body convulsing in the restraints.

Cain didn’t slow. He fucked me straight through it, hips snapping faster, sweat dripping down his chest onto my bouncing tits.

But he still didn’t come.

Instead, he pulled out, uncuffed my ankles, and flipped me onto my stomach. He yanked my hips up so my ass was high, face pressed into the mattress, and drove back into my dripping cunt from behind. One hand fisted my hair, the other reached around to rub my oversensitive clit.

“You’re going to sign the papers tomorrow,” he grunted, slamming into me. “Full power of attorney over your academic future. Or I send the videos I’ve been recording of you to the entire department.”

My eyes widened in horror even as another orgasm built. “Videos…?”

He laughed darkly and thrust even deeper. “Every session. Every time you begged for your stepbrother’s cum. Including right now.”

The betrayal and overwhelming pleasure mixed into something toxic and addictive. I came again, screaming into the sheets, my walls gripping him like I never wanted him to leave.

Only then did he let go.

With a guttural groan, Cain buried himself to the hilt and exploded. Thick, hot jets of cum flooded my womb, pulse after pulse, so much it overflowed and ran down my thighs. He kept grinding through his orgasm, making sure every drop stayed deep inside me.

He collapsed over my back, still buried inside me, lips brushing my ear.

“Sleep, little sister. Tomorrow you become mine completely.”

I passed out from exhaustion, chained and full of his seed.

When I woke hours later, the cuffs were gone. Cain was asleep beside me. My phone was on the nightstand.

I grabbed it with shaking hands and opened the gallery.

Dozens of videos. Me on my knees. Me bent over his desk. Me screaming his name at the cabin.

But there was something else — a new folder labeled “Previous Subjects.”

I clicked it.

The first photo made my blood freeze.

It was me… two years ago. Before our parents even met.

He had been watching me long before I knew he existed.

How long had Cain truly been planning to claim me? And with the evidence of his past victims now in my hands, could I escape the cabin before he woke up… or would my twisted addiction to his cock keep me chained here forever?
