My Professor's Obsession

The Weight of Knowledge

The bruises on my soul were starting to match the ones on my skin.

The drive to the Glass Cage the next night felt like a descent into a beautiful, high-tech tomb. The image of those sketches—me at nineteen, me at twenty, me in a mask I hadn't even bought yet—burned behind my eyelids like a brand. Caspian hadn’t just chanced upon my ruin; he had curated it. He had watched my family crumble and my brother spiral, waiting for the exact moment I became desperate enough to sell myself to the only man who could "save" me.

The hydraulic doors hissed open, and the cold, salt-tinged air of the studio hit me. Caspian was already there, standing by a massive slab of black granite that served as a secondary posing table. He didn't look up from the charcoal he was sharpening with a surgical blade.

"Five minutes early," he noted, his voice a low, clinical vibration. "Knowledge seems to have made you punctual, Seraphina. Or perhaps just more afraid."

"Why did you do it?" I whispered, my voice trembling as I stepped into the spotlight. I knew I was risking another ten days on the contract, but the silence felt like a physical weight in my lungs. "Why me? There are a thousand girls at Aethelgard who would have given you their souls for free."

Caspian finally looked up. His eyes were arctic, stripped of even the dark heat from the night before. "You're breaking the silence again. That’s another ten days. Keep talking, and you’ll be my guest until you’re thirty."

He walked toward me, his boots clicking with a lethal rhythm on the stone floor. He didn't touch my face tonight. He grabbed my arm, his grip like a vice, and led me to the granite slab.

"Tonight, we test your endurance. Strip. Every stitch."

I obeyed, my fingers fumbling with the buttons of the black silk dress he’d demanded I wear. Standing naked under the harsh LED spotlights, I felt like a specimen under a microscope. He didn't wait for me to get comfortable. He picked up the iron collar, the metal chilled from the studio air, and snapped it around my neck.

"On the table," he commanded. "On your back. Arch until only your heels and your shoulder blades touch the stone. Arms stretched over your head, wrists crossed."

It was a bridge pose—brutal, exhausting, and designed to make every muscle in my core and thighs scream within minutes. As soon as I took the position, he used a thin silk cord to anchor my crossed wrists to a ring bolt in the floor behind me. My chest was thrust upward, my p***y exposed and aching, my stomach flat and trembling from the strain.

"Don't move," he hissed, leaning over me. "I want to see the way your muscles cord when you’re fighting for breath. I want to see the exact moment the pride leaves your eyes."

He went back to his board. For an hour, the only sound was the scratching of charcoal and the rhythmic crashing of the Atlantic outside. My legs began to shake. A bead of sweat rolled down my ribs, stinging a small scratch on my hip. Every time my hips dipped even a fraction of an inch, Caspian’s voice would cut through the dark.

"Higher, Sera. If you drop, I add a week."

He was harsher tonight, his clinical coldness a sharp contrast to the man who had banged me against the garden wall. It was as if knowing his secret had stripped away the last of his humanity. He wasn't a lover or even a savior; he was a collector, and I was his prized, broken thing.

"You think you’re a victim," he said suddenly, his voice loud in the silence. He didn't stop drawing. "But you’re a collaborator. You liked the way I took you in the dark. You liked that I was the only one who saw through the 'perfect' St. Claire facade. You didn't want a boyfriend, Sera. You wanted a master."

I bit my lip to keep from sobbing. My muscles were on fire. I could feel the wetness between my legs—a treacherous, humiliating response to his verbal flaying. My p***y throbbed with every heavy beat of my heart, the iron collar pressing into my windpipe as I struggled to hold the arch.

"Session over," he finally said, the charcoal snapping with a sharp crack.

I collapsed onto the granite slab, my limbs like jelly. I couldn't even move to cover myself. Caspian didn't offer a hand. He simply turned off the spotlight, leaving me in the dim gray light of the moon.

"Dress and go. I have a faculty meeting at eight."

I dragged myself to my feet, my body feeling like it had been through a war. As I reached for my dress near his desk, I saw my phone screen light up with a notification. It wasn't a text from Dominic or a news alert. It was an encrypted message from an unknown number—the same one Vane used when he was in trouble.

I swiped it open. It was a photo of Vane sitting in a dark car, his face bruised, a man’s hand visible on his shoulder holding a heavy gold ring with the Blackwood crest.

Below the photo was a single line of text: "The debt isn't just about money anymore, Little Bird. If you run, he doesn't just go to jail. He disappears."

I looked up, my eyes finding Caspian in the shadows. He was watching me, his silhouette tall and unyielding against the glass. He didn't say a word, but the message was clear. I wasn't just a model, and this wasn't just a thirty-day deal.

I was in a cage with no key, and the man holding the bars was the only one who could keep my brother alive.

"Problem, Miss St. Claire?" he asked, his voice smooth and dangerous.

"No," I whispered, clutching the phone until my knuckles turned white. "No problem, Professor."

"Good," he said, stepping into the light to adjust his cufflinks. "See you in class. Try to look like you haven't been banged into submission. It’s bad for my reputation."
