"The next time you decide to disrespect me, you won't be so lucky."
The Professor's threatening words from yesterday echoed in Rebecca's ear as she sat at her desk, waiting as the other students filed past her and out of the classroom. She'd tried her hardest, but couldn't keep her mind from wandering. Some of the other girls glanced at her in pity, but most hurried past, glad they weren't in her place today.
As the classroom door slammed shut for the final time, the Professor locked it firmly, and then strode to where Rebecca sat waiting anxiously. He glared down at her, then barked, "Stand up and walk into my office. Now."
She stood on shaky legs, and quickly stepped through the aisles of chairs to his office, through a side door out of the classroom. It was dark, but he hadn't given her permission to turn on the light, so she stood trembling in the black space. She gasped as he suddenly grabbed her hair, shoved her forward into a chair, and tied her down into it faster than she could react.
While she began to struggle against the restraints, still in shock, the Professor flipped on the light switch. After a moment of her eyes adjusting, Rebecca took in the scene, and her eyes filled with tears. She had heard about the Professor's Punishment Room, but had hoped she would never have to see it. She had tried so hard to pay attention and be good and not break a single rule, but apparently, it hadn't done her any good.
Now, she was strapped to a chair with an open seat, her knees restrained in stirrups and pressed back towards her chest, leaving her underwear exposed. Her arms were also tied back, and a strap across her midsection prevented her from even shifting in the chair.
"Rebecca. Have I told you how tired I am of you little private school bitches thinking you're too good for anyone?" His voice was quiet and kind, but Rebecca heard an undercurrent of cold malice that made her shiver.
"Please, I'm sorry, I'll try hard-" she broke off in a gasp as he cracked his knuckles across her face.
"Shut UP!" He snarled in her ear, tangling one hand in her hair. The other shoved inside her panties, roughly spreading open her pussy and jamming two fingers inside. The terrified girl started sobbing, both at the pain of the rough intrusion and the humiliation of being molested while spread so openly to her teacher's eyes. "Oh, please, as if you don't love it. All you slutty little cunts love getting fucked open every chance you get."
The poor girl was openly crying, and gasped out between the Professor's thrusts, "I don't! I don't, I've never had sex, please stop it hurts!"
The man paused, fingers still buried in her pussy, and looked down at the sobbing schoolgirl. "Interesting...you do feel tighter than the other cunts I get in here. And you are...new." He wiggled his fingers, taking his time to notice the barrier just beyond his fingertips. "I'm glad you told me, young lady," he said, pulling out, "we have a policy here of letting the head teachers break in all new students. As the head of your department, I look forward to ruining your young cunt."
He stepped back, suddenly, and pulled her skirt up so it was bunched around her waist. Taking a knife out of his pocket, he cut the waistband of her underwear, making her cry harder. She pulled against the restraints, trying to close her legs or cover her violated pussy, but couldn't. She watched the Professor bend down out of her sight, and when he straightened, he held a small remote control in his hand. "But until then, Princess," he smirked, "I'll break in that sweet ass of yours."
Rebecca sobbed in horror and pulled at the restraints as hard as she could as she watched him press the button and heard a mechanical noise beneath her. She felt something rubbery and cold press against her bare asshole, and openly started begging. "Please, please Jesus no, I can't I can't do that you can't do this to me-"
The Professor pressed another button, and the pressure stopped. "Young lady, you'll realize I can do whatever I like. So can any other staff member in this school. Until you learn that, reeducation is going to be a very painful experience for you." With that, he turned the switch back on, and a thick dildo began to push its way into Rebecca's virgin ass.
"I could fuck your asshole open on my own cock, of course, but I want you to be fully aware of how little control you have here," the Professor laid out, his voice clear and strong over Rebecca's tortured cries. "You are," he paused to hear her scream as the head of the dildo popped into her asshole, "beneath me. You are worthless. You are my toy slut, and if I want to wreck your shitter on a piece of plastic, I will." He pressed another button, and 9 inches of thick silicon began to grind slowly but surely into Rebecca's ass. She was screaming and sobbing as she felt her tiny asshole spread open for what felt like a soda-can thick rubber cock, and tears flowed down her face as she shook with agony and humiliation. She would do anything to make it stop, and she told him so.
"Anything?" The Professor purred, taking his fingers and spreading her pussy lips open as far as he could. "Would you beg me to fuck this slutty pussy with whatever I chose to put inside you?" She clenched her teeth, and shook her head. He sighed. "A pity. Some lessons have to be learned the hard way, I suppose." He turned up a dial on the remote, and the speed and force of the dildo in Rebecca's ass increased. She devolved into a mess of ugly sobs as she felt her asshole give way to the intruder, and let herself be fucked open in front of her teacher. However, as he continued increasing the force, she began screaming anew, her eyes wide with pain and terror as her body shook with the force of her anal rape. The cock below her drove into her bowels with a mechanical rage, shoving itself into her guts dry and splitting her tiny asshole open so wide she thought she was dying. Finally, after several minutes of helpless sobbing and screaming as her shitter was reamed on 9 inches of silicone cock, she broke. "Please make it stop, I'll do it, I'll do anything just make it stop and I'll beg you to have sex with me."
The Professor sneered at her, refusing to ease her pain. "Do better than that." He shoved one finger inside her pussy, making her cry out with the sensation of being raped in the ass and fingered in her cunt. "Beg me to bring the other teachers in and run a train on you all night. Beg me to keep you as my little anal whore and never touch your pussy."
She shut her eyes tight, and gasped out in choking sobs, "please Sir let your friends wreck my pussy, yse me however you want, do whatever you want to me just take this cock out of my ass!"
He laughed, and pressed a button. She sighed in relief as the dildo withdrew from her asshole, wincing as it popped free. With the same smirk on his face as when he raped her ass, the Professor picked up his office phone, and made a call. "I have a new girl in my office," she heard him say, and then he hung up the phone.
