I smooth down my skirt and button up my cardigan, trying to look prim and proper as I head into Professor Thorne’s 8am lecture. But I can’t help grinning to myself knowing what’s hidden beneath my conservative outfit. The cold metal of my chastity belt presses against my skin, a delightful secret I’ll only share with one person today.
Professor Thorne is already at the podium when I slide into my seat near the front. His lecturing style is dry, but I find myself captivated by his air of authority. My mind starts to wander to naughty places, imagining what he’d do if he knew about my little secret.
The lecture proceeds and I find excuses to touch his arm to ask questions, lean in close to whisper. I drop innuendos about being “trapped” and “needing his key.” He raises an eyebrow at my forwardness but I just bat my lashes innocently.
When the lecture lets out, Professor Thorne calls me to his office. “Ms. Pia, a word about your participation today…”
I lock the door behind us and saunter over to his desk, hiking up my skirt to reveal the glint of the chastity lock. Professor Thorne’s eyes widen.
“What is the meaning of this, Pia?” he growls, voice deep and commanding.
I coyly cover myself. “Oh Professor, I’m so pent up I don’t know what to do! Would you be willing to help me out?”
We engage in a back and forth, him demanding answers, me feigning innocence and vulnerability, until he grabs me firmly by the shoulders.
“You wicked girl! You come in here in that outfit, drop hints all class, and now you tease me, flaunting what you won’t give up? You’re determined to torment me until I crack, aren’t you?”
He spins me around and bends me over his desk. My heart races as he flips my skirt up, exposing the chastity belt.
“Where is the key?” He demands. “Tell me where that key is, NOW.”
“I…I don’t have it on me. My ex took it. Besides, you wouldn’t really stoop so low as to steal a key from a student, would you Professor?” I look back at him coyly.
He exhales deeply, grip tightening on my hips. Then suddenly, he releases me and strides to his door. I gasp as he locks it with a resounding click.
“You may not have the key, but you won’t be leaving my office until you give me everything I want.”
He returns and grips my chin, forcing me to look into his intense eyes. “I’m going to take what I need, one way or another. Understand?”
I nod meekly, heart pounding, as he pushes me down onto the desk. He rips my cardigan open, sending buttons scattering. Cool air hits my bared breasts as he unclasps my bra.
I bite my lip to stifle a moan as rough hands grope and squeeze. He tugs my skirt up around my waist and hooks his fingers in my panties, yanking them down.
“I’m going to own every inch of you,” Professor Thorne growls. “Mark you, ruin you for anyone else.”
He hikes my leg up and I feel his hard cock pressing at my entrance, demanding access. The chastity belt prevents him from entering fully. Frustrated, he flips me over and attacks the lock with his belt buckle, the muffled clanks echoing in the room.
Finally, he manages to break the lock. I cry out as he sheathes himself inside me fully, stretching me deliciously. He sets a relentless pace, desk creaking with his powerful thrusts.
“I knew you were a filthy girl the way you look at me,” he pants, pounding into me from behind. “I’m going to fuck you until you can’t walk.”
He slams me onto the desk prone and unhooks my belt completely. Now he can rail me even harder, his heavy balls slapping against my clit with each crushing thrust.
“You wanted to be locked up, Pia? I’ll lock you up on my cock,” he smirks, grabbing my hips in a bruising grip.
Pressure builds inside me as his cock drags along my sensitive walls. “Please Professor, I’m going to-“
“Not until I say so.” He lands a sharp spank on my ass. “You held out on me long enough. Now you’ll come on my terms.”
He drives into me at a furious pace, my pussy clenching around him. Just as I reach my peak, he slips a hand around to rub my clit.
“Now, Pia. Come for your Professor,” he commands.
My orgasm crashes through me and I clench like a vice around him. He groans and drives deep, spilling himself inside me as my walls milk him.
I collapse onto his desk, utterly spent. Professor Thorne smooths my hair and whispers in my ear.
“Was that all you had, Pia? Or are you still hungry for more?”
I smile and clench my pussy around his softening cock. “Oh, I’m just getting started.
