Private Tutoring: A Kinky Hogwarts Story



Chapter 1 – Tonks’ Request



Two years after the Battle of Hogwarts…



Night had fallen over Hogwarts University of Witchcraft and Wizardry, and in the darkness shrouding its ancient, labyrinthian halls, only the soft light emanating from the tip of her wand and the click of her high-heeled boots upon the floorstones betrayed Cho Chang’s passage towards the Room of Requirement. This was no rule-breaking midnight escapade, the note protectively clutched in her left hand permitting her to move about the castle after lights out and signed with an authority only Headmistress McGonagall could countermand, yet the Ravenclaw beauty quickened her pace all the same, the tales of the punishments meted out by the loathsome Argus Filch against any students he caught wandering the castle past curfew too engrained to let her rest easy. Only when she finally reached her destination did she let herself relax, a slender hand gently knocking against the door. “Professor Tonks?”



At her touch, the door swung wide of its own accord, and Cho took that as permission to enter, chocolate-brown eyes glancing about at every detail added that evening. Hogwarts had been steeped in magic from the moment the Founders had laid down the first foundation stone, and the Room of Requirement was no different, its appearance, layout, structure and contents able to transform on a whim to meet the needs of its inhabitants. At sixteen, when she ventured to this place in secret as part of Dumbledore’s Army, it had served as their training area and headquarters. Now, four years later, the Room had been transformed into a private retreat, cozy and inviting. At the right-hand wall, a fireplace roared to life at her approach, casting its light over a pair of formal high-backed chairs set before it, a small table placed between them arrayed with teapot and cups. Elaborately woven rugs muffled the sound of her heels as she walked, while old-fashioned wooden screens demarcated the back of the room from the rest of the space, upon which half a dozen articles of stray clothing had been draped over. Finally, a colossal four-poster bed dominated the room, silken curtains and sheets enshrouding a mattress upon which four people could sleep comfortably, and the beginnings of a blush spread across Cho’s fair, beautiful features at the realization she’d stepped foot into someone else’s bedroom. “Hello? Professor Tonks?”



The wooden screens were pulled back, and dark eyes shone with genuine delight at the visitor’s presence. “Wotcher, Cho, it’s good to see you! Make yourself at home!” declared Nymphadora Tonks, the new Defense Against the Dark Arts teacher. “Sorry about the mess; I keep saying I’ll clean this place up, yet I can never seem to find the time.”



“I— if I’m being a bother, Professor, I can come back,” stammered Cho. “I wouldn’t want to intrude on your privacy.”



“Oh, tosh,” said the former Auror, giving the suggestion a dismissive wave. Though a capable hunter of Dark wizards, sheer luck alone had ensured her survival during the Battle of Hogwarts, and following an extended period of recuperation, she’d resigned from her role to join the Hogwarts faculty, her skills and experience now serving to help its students better protect themselves. “I invited you here tonight, remember? And no need to be so formal either. ‘Professor’ is all well and good in the classroom, but here, you can just call me Tonks, all right?”



“All right, Profe—Tonks,” Cho corrected herself at the last moment. “Is this where you’re staying in the castle?”



“No, my actual apartment is close to the Hufflepuff dorms, I just use the Room of Requirement whenever I need to clear my head. And sit down already, you’re making me antsy hovering there like that. Tea?”



“I’d love some, thank you,” Cho said, taking the proffered seat and cup. This was the first time she’d ever spoken to the older woman in private, never mind a casual setting such as this, and she felt the first stirrings of anxiety rise at the unfamiliar situation. It certainly didn’t feel like Tonks was about to upbraid her for some mistake she’d made in her combined university-level DADA class, and nothing she knew about her suggested she liked to toy with her students. All the same, it was a struggle for Cho not to smooth her black pleated skirt out of nervous habit, and the Ravenclaw girl gave her host a surreptitious glance in hopes of getting a read on her.



It didn’t help matters that Tonks was oddly… intriguing. Cho’s sexual tastes ran exclusively towards men; the few experimental kisses she’d shared with some of the other Ravenclaw girls years ago had been pleasant enough, but nothing she felt eager to repeat, and no woman had come close to capturing her heart the way Cedric and Harry had. Yet she had to admit, there was something alluring about Nymphadora Tonks, and after a few moments’ consideration, realized that it was her confidence. As a Metamorphmagus, Tonks could be any woman she wished, her appearance and physique endlessly transmutable thanks to her innate shapeshifting abilities, yet more often than not, the woman who could be anyone insisted on being nothing less than herself. A shock of short, spiky, bubblegum-pink hair, more suited to a punk rock guitarist than a battle-hardened Auror, proclaimed herself to the world, while a pair of metal piercings on the right side of her sharp nose offered a further mark of distinction. Her outfit was similarly eclectic. With class over with for the day, the Defense Against the Dark Arts Professor had exchanged her formal robes for an old pink memorabilia t-shirt of the Weird Sisters rock band, over which she wore a strict leather corset, of all things, the garment clinging tight to her upper boy and flattering her more feminine dimensions. A pair of worn, hip-hugging blue jeans and tall wedge-heeled black boots completed the ensemble, and at Cho’s scrutiny, gorgeous red lips curled up in a smirk. “See something you like, Miss Chang?”



“Merlin, I’m sorry… I didn’t…” Cho’s gaze settled into the depths of her teacup. “My apologies, I should not have gawked at you.”



“Oh, gawk away, I know it’s not the normal fare,” Tonks acknowledged. Dark eyes, veiled by eyeshadow, looked the Ravenclaw beauty over, provoking another cheeky smile. “Merlin knows I can’t rock the school uniform like you can.”



Blushing profusely, Cho mumbled her thanks, running a hand through her long, raven-black locks. With the end of the war and the introduction of post-secondary and graduate studies to the Hogwarts curriculum, new uniforms had been prepared as well. Most days, she’d preferred to wait until she’d retired for the evening to change into more casual attire, and so the Ravenclaw beauty remained in the standard outfit for the university-age female students: a white cotton blouse and Ravenclaw-pattern tie, over which she wore a black sweater with Ravenclaw House’s colours banded at the wrists and waist, along with a short pleated black skirt and dark nylon pantyhose. Her one deviation from the dress code were the stiletto-heeled, knee-high black leather boots she habitually wore, adding a few inches to her height and further highlighting her long, shapely legs. Time had yet to dull her grief, ease her regrets or restore her confidence, but it had transformed an already pretty girl into a genuinely beautiful young woman, and she was self-aware enough to know the effect her looks had on others, even if she remained disinterested in taking advantage of them. “So, what did you want to see me about?” Cho asked, eager to change the subject. “Did I do something wrong?”



“What? Oh, no, nothing like that,” insisted Tonks. “And why would I need to punish you anyways? You’re one of my best students. In fact, I’ve been meaning to tell you how much you’ve impressed me. From what I’ve heard, you absolutely aced your NEWTs, and everything I’ve seen in class tells me you deserved it. I know things were hard for you after Voldemort returned, and it’s good to see it hasn’t kept you from succeeding.”



“That’s kind of you to say,” Cho muttered, her mien darkening as her thoughts drifted to the black days after Cedric’s death, and all the regrets that followed in their wake. “I’m not entirely sure I agree with you.” Not after I messed up so completely with Harry. “But I appreciate the sentiment all the same.”



“It’s the truth. I have noticed you’ve been looking a little tired over the past couple weeks, though. Everything all right?”



“Oh, yes, I’m fine, I’ve just been very busy lately. Between all my classes, getting ahead on my papers and taking up Quidditch again, it’s just hard to find a moment to catch my breath, that’s all.”



A pink eyebrow raised questioningly. “You’re actually ahead on your schoolwork?”



“Well, we Ravenclaws do have a reputation to maintain,” Cho asserted gently. “After everything that’s happened since the Tri-Wizard Tournament and after all the ways our education has been disrupted, is it so hard to believe I’d try and get as much done as possible before the next catastrophe strikes?”



“A fair point,” Tonks laughed. “Truth be told, it’s good to know you’re on top of things. I called you here because I’d like your help in setting up a class project for tomorrow, and believe me, it’s not the sort of thing I’d ask anyone unreliable.”



“Really?” asked the Asian beauty, unable to keep from smiling at the compliment. “I’d be happy to assist.”



“Steady on there. Let me explain what I need from you before you agree, okay? And again, this is a request. I won’t force you to help me, and you won’t be penalized for refusing. Understand?”



Now I am intrigued, Cho mused inwardly, that reassurance all the spur her curiosity needed to take hold. She couldn’t say that she knew Tonks particularly well, but as far as she was concerned, anyone who’d risked death fighting against Voldemort and his Death Eaters was in good standing. Likewise, that Headmistress McGonagall deemed her worthy of the Defense Against the Dark Arts position spoke volumes about her trustworthiness. And then there was the matter of her friendship with Harry, a bond she admired and envied in equal measure… “Professor, I know you would never ask me to do anything reckless, illegal or unethical, and that you’d come to me for help at all means more than I can express. No matter what, you can rely on me.” Like Harry should have been able to…



Tonks grinned broadly, and for a brief instant, Cho saw the image of a cat eagerly accepting a mouse’s fealty flash in her mind’s eye. “Then tell me, Cho, have you ever been tied up?”



It took a moment for Cho’s mind to register what exactly the older woman was asking, so shocking was the query, and when it did, the Ravenclaw’s blush only intensified, chocolate-brown eyes intensely examining the table’s construction, words dying unspoken upon her pouty pink lips. “Hey, it’s okay,” Tonks said reassuringly, gently cupping Cho’s right cheek and lifting her head to meet her gaze. “If you feel uncomfortable being here--”



“No, no, it’s fine,” Cho insisted, taking a deep breath to restore her equilibrium. Come on, Cho, after everything that’s happened, do you really want to disappoint someone else you respect and value? “It’s just… I could do with an explanation, that’s all.”



“Yeah, suppose I should have started with that, shouldn’t I?” Tonks admitted ruefully. “Here’s the deal: tomorrow, the university-level DADA class will take part in a training mission I’ve designed. Their goal is to rescue a pair of hostages I’ve imprisoned somewhere on the school grounds, and I’d like you to be one of the captives. They’ll have until nightfall to find and free you, all the while I’ll be doing my best to interfere.”



“I… I see. And I’ll be bound for the duration, I assume?”



“Exactly. I’d like to say that with Voldemort gone, there’s nothing to fear, but we both know the Wizarding World still has its share of dangers. It’s important you know how to protect yourself if you should be kidnapped for real, Merlin forbid, and that includes escape techniques should they leave you tied up.”



“That makes sense,” Cho admitted. “To answer your question, I’ve never been tied up before, but after some of the close calls I had during the war, I can see how knowing what to do in such a situation could be useful. So I take it that the rest of the class will be graded on how well they succeed in rescuing the hostages. In that case, I need to escape myself to pass?”



“Not exactly. It wouldn’t be fair to punish you for failing to escape when I have no intention of letting you do so to begin with. And clever as you are, Cho, the odds of you getting out of this are pretty slim. So no, the hostages will not be graded for this, only the rescuers. And don’t worry about missing out either. I plan on doing a bunch of these rescue scenarios, and I promise you won’t be typecast as the damsel in distress. That said, you manage to get yourself untied tomorrow or even escape without outside help, you’ll earn yourself a whole pile of extra credits. Sound fair?”



“That sounds more than reasonable, Tonks, thank you,” said Cho. A growing sense of excitement took hold over the beautiful Ravenclaw, burning away her anxieties like the sun dispelling a morning fog, and curiosity demanded she make a final query. “May I ask who my fellow hostage will be?”



“Sorry, don’t want to give it away,” Tonks replied. “After all, in a real hostage situation, you can’t pick and choose who you’re imprisoned with. You’ll just have to overcome your differences and solve the problem together if you hope to escape, right?”



“Fair enough,” Cho acceded the point. There were certainly no shortage of candidates, for the university-level DADA class included students from all four Houses, most of whom had been in Dumbledore’s Army together. There was Hermione, of course, and Neville, and Luna Lovegood, and the Patil twins, and Susan Bones, and haughty Daphne Greengrass…



And Harry Potter himself, of course. A shudder of unexpected delight rippled along Cho’s spine as she imagined herself being rescued by her former boyfriend, strong, dexterous hands attending to her bonds, the romantic feelings they’d once experienced for one another resurrecting stronger than ever…



It was a fantasy, of course, and a foolish one at that, for in her heart, Cho knew that Harry’s was forever beyond her reach now, an appropriate punishment for her many failures. Her sixth year at Hogwarts had been a painful one, Cedric’s loss an open wound that stubbornly refused to heal, and in the four years since, rarely a day passed when she did not linger on her mistakes; how her own pain blinded her to Harry’s needs, how she stood by Marietta after she betrayed the DA, how her relationship with Harry had collapsed… No, he’s far better off without you, Cho reminded herself, loath to cause him any further pain. The pleasant civility with which he treated her these days was far more than she had any right to expect of him, and that she might ever earn his trust or respect or forgiveness was presumption of the highest order. Moreover, from everything she’d seen, he was happy with Ginny Weasley, and he was far too honourable a man to ever betray his girlfriend for anyone, let alone her.



And yet, the fantasy stubbornly refused to die, like smouldering embers in the hearth waiting to be stoked into new flames. She knew she could never have Harry, and that made her want him all the more, a desire as intense as it was irrational, despite her best efforts to move on. With that, the decision was made, for how better to impress a Gryffindor than to act with courage and refuse to let anxiety and doubt hold her back? If nothing else, this will be a novel experience. “Very well, Professor, I promised you’d be able to rely on me, and I won’t break my word. I will be your hostage. Just do not go easy on me; I fully intend on escaping on my own, and I want to do so on my own merits.”



“Oh, is that so?” the former Auror quipped, teeth gleaming in a wide smile. “Bold words, Ms. Chang. Let’s see you live up to them. Shall we get started?”



“Certainly,” said Cho, rising from her chair. “Though I have to admit, I am new to all this.”



“Don’t worry about it, my dear, you’re in very good hands. First off, your safety is my absolute priority. All the ropes I’ll be tying you up with have been enchanted so they won’t cut off your circulation, while I’ve also charmed the gags so your breathing will be unaffected.”



“Safety features a real kidnapper wouldn’t bother with, I’d imagine.”



“Probably not, but a good teacher is responsible for their students, right? I can’t pretend spending all day bound and gagged will be the most comfortable thing in the world, but you will not be hurt. Understand?”



“I understand, Tonks, and thank you.”



“Good. Next, we need a safeword.” Chocolate-brown eyes blinked in confusion at the unfamiliar term. “Basically, a signal to let me know things are getting too intense, so I can release you. Think of something distinctive, something you’d never say in ordinary conversation, and I’ll enchant your gags so that I’ll hear it loud and clear. Any ideas?”



“Let’s go with ‘Malfoy’,” Cho suggested with a grimace. Much of the Hogwarts student body had returned to the school for its new university curriculum, yet Draco Malfoy and his many cronies in Slytherin House were not among them, a fact for which Cho was rather thankful. Though pureblood herself, the Ravenclaw beauty held nothing but contempt for the bigoted attitudes that had fuelled Voldemort’s rise to power, and the mood of the entire school had greatly improved without arrogant, elitist bullies like Malfoy darkening its halls. “Merlin, I can’t stand that creep.”



Tonks smiled. “A good choice. And don’t be afraid to use it either. Again, you’re not being graded on this, so you needn’t push yourself if you’re feeling uncomfortable. Worst comes to worst, I’ll leave you unbound in a cell somewhere, and that would serve the scenario’s needs. Finally, are you all right with being drugged asleep? The potion I’ll use shouldn’t have any side effects, but I wanted to get your permission, just in case.”



“If you say it’s safe, then I trust your judgement,” expressed Cho. “A real kidnapper might use something like that, so better I learn to recognize it now.”



“That’s the general idea. Any questions?”



Cho shook her head. “Then why don’t you go freshen up while I finish preparing?” Tonks offered. The wooden screens parted of their own accord, giving Cho a glimpse of the door that manifested out of the formerly blank stone wall, as the magic of the Room responded to Tonks’ need. “Might as well make yourself comfortable before we get started.”



It was good advice, and Cho accepted it with a grateful bow before stepping through the newly-created door. Beyond, a lavishly appointed three-piece bathroom waited for the Chinese beauty, the brasswork faucets and ornamentation sculpted into avian designs, a reflection of the private apartment she held in Ravenclaw Tower, produced by mere moments by the same ancient magic imbued into the very construction of Hogwarts. No sooner had she finished attending to herself than the first tendrils of doubt began to creep back in, invasive and unwelcome, threatening to rob her of her conviction. It’s going to be fine, Cho told herself, using the breathing exercises she’d learned from her therapist. There’s no shame in being nervous; you’ve never done this before, so it’s completely understandable. But you can’t let it stop you either. You fought against the Death Eaters, for Merlin’s sake. You can handle being trussed up for a day.



Slowly, grudgingly, her anxieties began to settle, like a pond returning to stillness after the ripples faded away. Taking a moment to ensure her dark nylon pantyhose was smooth and tight over her legs, Cho took a final deep breath, before stepping back out in the bedroom, head held high. “Professor Tonks? I’m rea--”



Where the room stood silent and empty, the older woman absent as if she had never been. Instincts still keen from the battles against Voldemort and his Death Eaters sprang into action, and her wand was out and ready in half a heartbeat. Cautiously, the Ravenclaw beauty stepped forward, peering about for any sign of her teacher and finding nothing. “Professor? Are you here?”



Only the echo of her own voice sounded in answer, the once-comfortable surroundings of Tonks’ refuge now strangely menacing and unwelcome. Heart thumping at her breast, Cho moved towards the exit, her anxieties bubbling up uncontrollably now. She said she needed to finish preparing. Maybe she needed to gather a few--



The sound of a single footfall directly behind her was the only warning Cho received, and a moment too late, she realized that the exercise had already begun. With a viper’s quickness, a gloved hand shot out of the shadows where the light of the fireplace failed to reach, seizing her right wrist in an iron grip and wrenching it away so that her wand was pointed uselessly towards the wall. Simultaneously, Tonks’ left hand came up, and Cho’s scream was smothered by the reeking white cloth clamped firmly over her nose and mouth. “Concealment Charm, my dear,” the former Auror whispered into her right ear, close enough she could feel the tickle of warm breath against her skin. “You must always be aware of your surroundings.”



Merlin, no! How could I let myself be caught so easily?! “Mmmpgghhh!” Cho gave a muffled cry, long booted legs kicking out. Blind panic took over, the understanding this was all an exercise lost in the heat of the moment, and her lithe, toned figure bucked and thrashed in her captor’s grip like some wild beast ensnared in a hunter’s trap, back arching, dark hair flying about, left hand clawing frantically away at Tonks’ own in hopes of prying the cloth away. A heartbeat later, the noxious, almost nauseatingly sweet stench impregnating the material began to overwhelm Cho’s senses, leaving her head swimming and darkness closing in on the edge of her vision. No, I… I can’t fail… “Mmmmppgghh…”



“That’s it, just breath it in,” crooned Tonks. Slowly, Cho’s struggles faded, her cries devolving into soft, sleepy moans, and Tonks let the drug-soaked cloth work its magic for a moment longer before withdrawing it and gently laying her prize down onto the bed, raven-black hair stark and beautiful against the backdrop of the crisp white sheets. “You’re so beautiful, Cho,” Tonks exclaimed, permitting herself a moment to indulge in the sight of her captive, so lovely in her helplessness, before she pried open Cho’s faltering grip to seize her wand. “Don’t worry, I’ll take very good care of this… and you, for that matter.”



Groaning, Cho tried to rise, only for her body to betray her, limbs leaden and unresponsive. “Pro… Professor…” she wheezed, left utterly spent by the effort. The first coil of rope encircled her wrists, pulling them tightly behind her back, and she tried vainly to dispel the fog clouding her thoughts. “Please—mmppggghh!”



The cloth returned to its rightful place, long, dark eyelashes fluttering helplessly as she strove to remain conscious. “Hush now, my dear,” Tonks urged her, planting a kiss on her student’s forehead. “You just relax and breathe it in. It’ll all be over soon.”



Exhaustion won out. Unable to resist any longer, Cho collapsed with a final, pitiful moan, athletic figure going limp. Can’t… can’t fail again… was her last coherent thought before the sea of darkness drowned her vision and dragged her under its depths…
