"If you'd been paying attention in class, whore," he punctuated with a bump of his hips, grinding his cock head into her cervix and making her gag with the fullness, "you'd know that when sluts get wet, their cervixes relax and retreat further up the vaginal canal, making more room for deep penetration. In other words, you have to come all over my cock before I can get all ten inches in you." He released her nipples and spread her pussy lips with his fingers again, forcing her to look at her tight cunt stretched around his thick shaft.
She processed his words slowly in between Jack's thrusts into her ruined asshole. Retreat. That's all her body wanted to do right now, retreat into herself and hide away, but instead she was in a humiliating position with her pussy and asshole spread for both her rapists to see as they violated her. There was no part of her that could hide, nothing she could do without them noticing. The thought of clenching around the Professor's cock and her own come dripping down it while Jack raped her ass made her cheeks flush, and her body shake with dread. He wouldn't be able to do that, would he? He couldn't make her come from being raped. She was suddenly very aware of his fingers rubbing her clit in time with Jack's thrusts, of how the burning drag of being anally raped was making her pussy clench against the Professor's cock for relief. As the Professor pulled a nipple into his mouth and sucked, the knowledge that no one was coming to save her, that everyone in the school knew she was in here being used as a fuckdoll and wouldn't do anything to help her, came crashing down around her. She hung her head and cried hopelessly as the two men fucked her holes, feeling her pussy squeeze in response to the stimulation against her will. They were taking both of her virginities at once, and forcing her to like it as an added insult.
"You know what I like most about ass raping little sluts like you?" Jack whispered in her ear, cutting through her helpless cries. He reached around her and grabbed her tits, pinching the nipples and holding them out for the Professor to lick. "Your assholes might try to force me out, but most of you have already taken so much cock you're practically worthless. When you finally come from this, though, it makes your ruined fucked-out holes clench around my cock and get tighter. It makes it more painful for you, of course," he paused to grind his dick deep in her guts, making her sob harder, "but it's so much better for me."
The thought of being worthless made her guts twist with desperation and anxiety along with cock, afraid of being tossed out like trash. Before she could stop herself, she heard herself saying, "Please don't throw me away, I promise I'm not worthless, I can be good for something!"
The two men chuckled, sharing a grin over her downcast head as she begged not to be abandoned. "Well, sweetheart," the Professor drawled, "unfortunately, you're not smart enough to pay attention in class, let alone be useful as anything more than a cum dump." She wanted to protest, to say that it was just a one time mistake, but was it? She remembered how hard it was to focus all the time, all the times her silly little brain wandered away. Maybe he was right. Sensing her submission, he added, "Besides, after a few more months of this, your holes will be so sloppy and used that we'll have to both fuck your ass at the same time just to feel anything." She broke down crying anew at the prospect of being double anally fucked as punishment for being ruined. He swept his thumb under her eyes to catch her tears, and said softly, "but you can be a good little whore for us now, right? You can be worth something by servicing us. You know, Jack," he raised his head, addressing the other man, "I think our girl here likes the way we talk to her. I think she likes being called out for what she really is, a whore stretched open on both our cocks. She got herself here, she's all drippy wet for us, I think this was what she wanted from the very beginning."
"Is that true, cunt?" Jack growled in her ear, picking up the pace of his punishing thrusts into her ass. She shook her head, but the look in her eyes held doubt. She was breaking, he knew that look. "Are you gonna be a good little bitch and come all over our cocks?" She bit her lip, stifling a whimper as the Professor stuffed another inch of his cock into her pussy. She was loosening up for him. "Look at you, you fucking whore. You want him to fuck you so bad. You want that last inch in your pussy, whore?" She hesitated, but he continued, "You want to make us both feel good, right?"
There it was. The tiny nod that told him she was finally accepting her fate. He switched to sharp, punching thrusts that sawed a full half of his cock in and out of her asshole each time, knowing from experience that soon she'd be coming whether she liked it or not. He knew how quickly the Professor could break a whore, and he wanted to pump his come into her ass just as she fell apart, so she'd feel that final deep painful thrust right as she felt the most pleasure.
"We're going to get you addicted to this," he grunted in her ear, shaking the chair with the force of her ass rape. "We're going to make you like the pain so much you won't be able to come without being fucked up the ass. We're going to have you begging to be filled up by whoever wants your holes. Pussy and ass out, tied to a bench in the hallway, there as a convenient fuck to anyone who comes across you. Let's hope they're generous and let you come to being raped, huh? Let's hope they're as nice as we are."
Finally, as she started to make those high-pitched noises that signaled she was close, the Professor shoved the last torturous inch of his cock into her tight pussy. She let out a little scream, spasming around his shaft, and he began to fuck her with short, fast thrusts that barely pulled any of his cock out of her at all, keeping her stuffed with all ten inches with no relief. His fingers rubbed and pulled at her clit, while his tongue and teeth worked her nipples until she was a shaking mess. All it took was for Jack to mutter, "that's it you fucking bitch, take this cock," before she was crying out, screaming, hands clenching in her restraints as she came hard.
Jack wasn't going to let her have that, though.
Just as her orgasm started, he reached down, spread her ass with both hands, and slammed his cock home. Her breath caught in her throat, her eyes flew open wide, and what started as a scream of pleasure turned into an agonized shriek as her ass was fucked deeper than it had ever been since it was first opened up on that dildo a scant two hours ago. Her stomach caved and she made a strangled noise in her throat as Jack filled her ass with cum, pumping her full until she felt she was bursting. All at once, he dragged his cock out of her burning anal tract, leaving her gaping asshole twitching while all his come spilled out on the floor. He sneered at her with disgust and disappointment as she sobbed, saying, "See? What did I tell you? You're just a ruined whore." He turned and left, closing the door behind him and leaving her with the Professor, still lodged in her pussy.
"He's right, you little bitch," the Professor grunted breathlessly, flicking her clit while he fucked his cock into her. He was close, and she let her head fall back, gasping with the shock of her stolen orgasm. "You don't deserve to come. You'll have to really prove that you're worth keeping, but at least you got a little taste, yeah? Don't worry, you'll get to feel so much more when we break you in over the next few months. You'll be on your knees riding a dildo, covered in cum and begging us to rape your ass. Look at you, look how fast you came from both of us raping you. What would everyone think if they knew how drooly and desperate you get for cock?" Finally, the Professor ground his cock in deep and dumped his come in her fucked-out hole. He only pulled out when it started to spill out around his cock. Unbuckling the restraints, he barked at her, "Get up and get out. Don't bother getting dressed, just grab your things and close the door on your way out."
Still blinking with disoriented confusion, she stumbled out of the harness chair, wincing at the pain in her pussy and ass, and began to gather her clothes. Before he could hurt her anymore, she fled the office, staggering out of the classroom and down the hall towards her dorm. The surreal change after what had happened was so sudden that it had her wondering whether her abuse was just a scene from a nightmare.
Which was exactly what her abusers wanted.
