The Restricted Section
Hermione Granger x Fem!Gryffindor!Reader x Harry Potter
Summary:
Harry wishes that Hermione would just relax. Just because he doesn't know the exact source of a hand-written spell in an old textbook doesn't mean that it's completely evil.
Intent to prove her wrong, he dawns his Invisibility Cloak and sneaks off to the Restricted Section of the library, looking for a more solid source of that spell - and he completely forgets everything that he set out to do when he finds Hermione along the way, doing something (or rather, someone) in a secluded corner of the library that is definitely not studying. (Something that he'll never be able to get out of his mind ever again.)
Hermione Granger x Fem!Gryffindor!Reader x Harry Potter. Accidental Voyeurism upon an Established Relationship. Smut/PWP. Set during Half-Blood Prince.

Full list of warnings and author's notes below the cut.
Warnings: this fic is primarily smut focused; there is some very vague plot - Harry and Hermione have an argument because Hermione doesn't like the Half-Blood Prince's book and wants Harry to get rid of it (and they are still not on good terms when the smutty stuff comes up); passing mention of a hex that gives you boils that never heal; the primary pairing in this fic is between Hermione and the reader, and Harry spies on them having sex using his Invisibility Cloak - that does mean that this fic has dubious consent and dubious morality, because Harry never asks for their permission to watch and never reveals himself to them, and during the course of this fic they also don't find out that he's there (if this is the kind of thing that makes you uncomfortable, then I would recommend moving on to one of my other fics); the reader has a vagina and uses she/her pronouns; the reader's looks - including race, hair colour, skin tone, etc. are not described in anyway; there is use of Y/N in this fic; the reader is a Gryffindor in this fic (I wanted her to be closer with Hermione, sharing a dorm with her, and be closer to the trio in general); Harry has had a crush on the reader for a while before this, but this is the first time he views Hermione sexually past his platonic friendship feelings for her; accidental voyeurism - Harry does not intend to spy on the girls, but once he discovers them, he doesn't stop watching; semi-public sex - Hermione and the reader are fucking in the library, but they are fucking in a much more secluded part of the library where Hermione knows that someone is less likely to discover them; there is some sub/dom dynamics - Hermione and the reader having a pre-existing sub/dom relationship where Hermione is very dominant and the reader is submissive, and Harry is understanding those dynamics as he observes them; Hermione calls the reader: little girl (not as indication of her size, but as a form of degradation and condescension), little bitch, little whore, slutty, brat, darling,; Hermione demands to be called 'Mistress'; Harry is a switch - he imagines himself as both dominant and submissive in his fantasies; (Harry as a 'sir' kink in his fantasies); mentions of creampie kink (one of Harry's fantasies); Hermione is very mean and condescending toward the reader; brat taming/punishment and reward - the reader has 'misbehaved' and Hermione seeks to correct it; degradation kink (towards the reader); Hermione fingers the reader; Hermione uses the reader's tie like a leash; lots of dirty talk (from Hermione); Harry considers masturbating but does not (because he fears getting caught) (and there is a mention of him masturbating to thoughts of what happened in a more private space afterwards); pussy spanking/clit spanking (from Hermione towards reader) and ass spanking (towards reader - just once) (no severe pain kink); orgasm denial (towards the reader); I believe that's it.
A/N: This was such a random idea that zapped into my head that demanded to be written. People were asking for Hermione x Fem!Reader smut and it was something I really wanted to do, but I only really felt inspired to do it when it occurred to me to write Hermione through Harry's eyes. To talk about her going from this very non-sexual being to someone so sexually powerful in his eyes - it was something really fun. And I am so glad I actually managed to squeeze this one in and finish it before the poll for the other fic finished up. I feel like this is such a fun, Harry Potter based idea that uses themes and elements unique to the series. And it's wonderful, filthy horny smut. So I hope that you guys enjoy!!
...
Harry really didn’t understand Hermione sometimes.
She was an amazing friend, someone that he wouldn’t trade for the world - someone so wonderfully loyal, smart, and fun to be around during the times when she let herself actually relax and untense. But during the times when she had that intensely large stick up her arse, she could be the biggest pain in the world. Sometimes, it was like she stayed up late in her dormitory, just thinking of ways to drive Harry and Ron utterly mad.
Yes, Harry knew that his particular fascination with the Half-Blood Prince’s book was not exactly… normal. But Hermione’s attachment to a lot of her books was never normal either. And just because the book was old didn’t mean that it was bad. Just because Harry was fascinated by it didn’t mean that there would be negative consequences.
There was no reason for her to go off on a long tangent about ‘dark magic’ and ‘the Latin origins of spells’ when he had asked her about a hand-written spell that was in the book. Something that spiralled into a huge argument between the two of them when he refused to hand over the Prince’s book once she had asked him where he had gotten the spell. To her, it was something that sounded very dangerous, and she complained that therefore, the whole book was dangerous. He complained that she had a knot in her knickers because he had just been asking if she knew what the spell was or not, if she had heard of it before - it’s not like he had any intentions of actually using it.
And then Hermione had warned him that he should simply throw the book away and he told her that she was just jealous that he was actually getting better grades than her in a class for once, and the night ended with her huffing off to bed and stomping up the stairs - and the two of them hadn’t spoken in over a day because of it. Ron was nagging both of them to make-up - but Harry was chuffed, honestly. For once, Ron knew what it felt like to be between two feuding friends, trying to mend the fences.
Harry wasn’t going to apologise.
Hermione wasn’t the queen of everything. She couldn’t just demand things from him and expect him to follow suit. He had his own brain, despite what she thought, and he could make his own judgements. Harry had no plans to use the spell if Hermione thought it was dangerous, and he had just been asking about it out of curiosity. But he was more peeved that it led to her demanding that he throw the book away or destroy it, like she held some authority over him, like she was his damn mother or something.
This left Harry stewing in his annoyance as he made his way to the Restricted Section of the library the next night. He was still curious if the spell had any other known origins - another spell book, some kind of book about dark magic. Hell, he would revert to a Latin textbook if he was desperate, just to get a leg-up without directly asking Hermione. But he was headed to the Restricted Section first - because as much as she was annoying, Hermione usually was right.
He was feeling confident and perhaps a bit cocky to find the source of the spell and wield some more knowledge over her that she didn’t have. For once.
Harry had dawned his Invisibility Cloak for this task, of course. It wasn’t past curfew yet, but the library was about ten minutes from closing, and he knew that it would be easier to sneak in before Madame Pince locked up and stay there well after dark, taking his time in order to find what he needed. And any trip to the Restricted Section without a note from a professor giving permission required such a disguise.
The library was practically deserted due to the late hour - most students having wandered off to bed like good rule followers. Harry wasn’t surprised when he heard a particular, familiar voice coming from an isolated area of small desks study carols back between a few towering book cases. Of course, she would think that this would be the perfect place to get her work done, undisturbed. He couldn’t hold back from rolling his eyes when he heard that voice taking on her usual scolding, bossy tone.
“I am not at all pleased with you, you know that?”
It was Hermione.
Harry knew for a fact that Ron was in a corner of the Gryffindor common room, his face unpleasantly glued to Lavender’s once again, so he wasn’t the one in the path of Hermione’s wrath this time. Harry had to wonder who exactly had come on the other end of her up-tight, nosy fortitude.
He had seen Hermione usher you off to the library after class earlier that afternoon, saying something about the mark on your last Transfiguration essay being ‘far below your usual standard’, and talking about how you ‘needed to follow her study schedule more closely’ - and Harry had felt sorry for you at the time, if anything. The fact that you would have Hermione hovering over your shoulder, bothering you all afternoon, marking all your work and making you redo it to her incredibly high standards.
Sometimes, he felt sorry for the fact that you had to share a dorm with her. That you couldn’t escape Hermione even for a peaceful night of slumber.
But surely the two of you hadn’t spent this long in the library together. Even you wouldn’t take three or four hours to do your homework up to Hermione’s standards. She would have freed you by now - and with any luck, you would be off somewhere, snogging some lucky bloke - (Harry couldn’t let that particular train of jealous thought get to him right now).
“Little girl, am I going to have to get mean with you?”
Hermione’s voice came again, just as bitter as usual, and then it clicked with Harry.
No, it wasn’t you, perhaps Hermione was taking out her anger on a couple of First Years for not doing their homework, getting on the wrong end of Hermione’s ill-guided Prefect power that she wielded like a presidency. Harry held back a scoff of laughter, and he couldn’t help the urge to move toward the sound of her voice, eager to see what exactly was going on.
“Stop being such a whiny little bitch - you asked for this. Now shut up and take it like a good little whore.”
Those words - those words in Hermione’s voice - immediately smacked Harry in the face harder than any stunning curse ever could have. He craned his neck around the bookcase in front of him so hard to see what was happening that he harshly smacked one of his shoulders, nearly giving himself away with the noise and having to strangle down his cry of pain in order not to be caught.
However, after a moment, he came around the corner completely and rested against the bookcase comfortably as his eyes took in the utterly unbelievable sight at the other end of the aisle.
Holy fuck.
Holy… fuck.
It was you.
You and Hermione. Hermione and you.
You and Hermione looking like some sort of unbelievable pornographic dream.
Hermione had you pressed up against a desk, your legs spread wide for her with your arse just balanced on the edge of the table while she stood between them - it took Harry’s very stunned brain a moment to process it, but he realised that her arm working furiously between your thighs like that, pistoning back and forth while you spread your legs wider and leaned into the touch could only mean one thing.
She was finger-fucking your pussy.
Harry had no clue how he hadn’t picked up on the other sounds previously, especially not in the dead quiet of the library. But it was blatantly fucking clear to his ears now. The sound of your wetness sliding against her fingers, so beautifully sloppy - he could only imagine how slick you were, how pretty your cunt looked around her fingers, which were usually only meant for gripping quills or turning the pages in her next book. Along with your repressed moans, barely caught in your chest where you were biting your lip raw, clearly trying your best to stay quiet - the sounds coming out, as Hermione had described them: whines, as though you were a needy bitch in heat.
Harry was in utter shock.
Never, in a thousand years, would ever have imagined Hermione Granger looking at you with crazed heat in her eyes, her stern brow and disappointed frown somehow so perfectly fitting for the situation. Scolding you in her bossy voice while she held on tight to your Gryffindor tie like a leash, keeping your posture tight and straight as she finger-fucked you in the most rough, harsh way that Harry could have ever pictured.
Hermione - uptight, bookish, rule-bound Hermione - fucking you in the library where anybody could have caught the two of you. It seemed so wildly unimaginable, and yet - when more scolding words came out of her lips in that bossy tone, it seemed… so terribly fitting for her.
“You’ve been such a naughty girl, haven’t you?” Hermione breathed hotly, giving another harsh tug on your tie that made you whine deeply in the back of your throat.
Harry swore the sound of her fingers jabbing between your legs became even wetter, sloppier sounding. So you liked being called naughty.
“Yes, I have-” You whined out, and Hermione tugged the tie again, cutting off anything further that you had to say with a harsh jolt.
Harry’s cock snapped to attention at an alarmingly fast rate, the blood rushing into his prick so quickly that it almost made him dizzy. The moral contention of watching two of his good friends go at it didn’t really cross his mind at all (perhaps his morality was going a bit too grey, using an old marked up book to ‘cheat’ in his classes these days). But he knew that wanking would be a bad idea simply based on the fact that he would have a difficult time staying quiet. So he reached down and squeezed the bulge in his trousers, gaining little relief from this as he looked on. He likely wouldn’t have been able to pull his eyes away if Voldemort himself showed up and demanded it.
“Such a naughty little bitch - you can’t even go one afternoon without having your slutty cunt filled, can you?” Hermione demanded, her words seemingly growing filthier by the second.
“I need it.” You moaned, arching into her further, as though you were possessed.
Harry would have wondered if she had been replaced by someone else, or bewitched - but you seemed to love it, loved everything she was saying. She seemed to be playing into a knowledge of your kinks, things that she knew would make you weaker and more lustful in her hands. Which was so Hermione that it was painful. Studying for something, keeping a backlog of useful knowledge.
Harry just never would have guessed that she would have used her big brain for this.
What made matters even more dizzying and shocking - this was Hermione and you. A pair he never would have thought up that also somehow made so much sense. Now, every single time the two of you snuck off giggling and Harry thought that it was just something girlish that he didn’t understand - he had to wonder what the two of you had been doing.
The fact that Hermione had been Viktor Krum’s date to the Yule Ball and you had been Harry’s, but you and Hermione had been glued to each other all night made a lot more sense. Every single time the two of you walked to class together holding hands, every single time you showed up to the Gryffindor table with some kind of glaring love mark on your neck and Ginny or someone else asked you about it and Hermione had laughed when you named off a different boy from a different house - it all made strange sense in Harry’s eyes.
This was you - one of the hottest, most sought-after girls at Hogwarts. The star of every single one of Harry’s wanking fantasies since you had given him a pity kiss under some mistletoe after a DA meeting. (He had a feeling that Hermione would be sneaking into those fantasies too, now, as much as he had tried to keep her out on the grounds that it would be rude to wank to his best friend). You, someone who was so gorgeous and so desirable and somehow never seemed to have a long-term boyfriend, as often as guys asked you on dates, and as often as you claimed to like certain boys and even flirted with them.
Apparently Hermione had been keeping you on a leash this whole time. A tight leash - just like the way she was holding your tie, keeping you close, keeping you waiting with baited breath for her next move.
“Mione-” You breathed out in return, a slight begging in your voice that had Harry light-headed in seconds.
This was better than any fantasy he could have dreamt up.
“Ah-ah. Hush, little girl.” Hermione fired back, that bossy condescending she always used somehow sounding all the more perfect in this context. “You’ve been such a proper brat all day, and you’re going to take what I give you, understand?”
You nodded your head (as much as you could with the hold she had on you) and made a noise of affirmation. But Hermione gave another sharp tug on your tie, clearly displeased with this.
“Come on, use your words now. Be a good girl.” She ordered sharply, the only thing giving away what must have been her own arousal being a slight hint of breath on her voice. Otherwise, she was entirely proper - not a single wrinkle in her impeccable uniform, her face entirely straight and firm as she stared you down with sharp eyes.
“Yes, Mione-”
“No, darling. Wrong again.”
Hermione hauled her hand back, creating another loud wet sound as she hauled her fingers out of your pussy entirely. Harry harshly craned his neck again, and it was only then that it truly occurred to him, between his dizzy head, his cement legs and his hard cock painful against his pelvis, protesting wildly against his zipper, that he could actually move closer to get a better look. With his Cloak guarding him, he would not be seen.
He tried his best not to rush, not to make too much noise especially as he got closer, and he almost scolded himself when he nearly missed out on it - the wet smack as Hermione brought her hand down between your thighs. If he hadn’t seen it with his own eyes, he never would have guessed that she had so boldly laid two rapid spanks right across your swollen, needy clit. Your skirt flipped up out of the way, no panties in sight, and giving her all the room in the world to do so.
You harshly bit down on your own lip again, worrying the skin to the point where it was swollen and looked like it might even bruise, dampening down harsh cries from deep within your chest. Before Harry could worry that the tears pooling in your eyes had meant that Hermione had truly hurt you, you spread your legs wider and canted your hips more toward her, offering your body up for more.
And then, you opened your lips again, seemingly to obey whatever implicit command she had given you with the spanks.
“Yes, Mistress.” You choked out, putting stress on the title, as if correcting your earlier self. “Yes, I understand.”
“Good girl.” Hermione replied, more breath this time as she used your tie to pull you into a heated kiss, and then shoved three firm fingers back into your waiting, leaking cunt.
Harry’s head was spinning.
He had never seen anything more beautiful and erotic in his life (not even when Fred and George had shown him and Ron those Wonder Witch magazines - no, this was much hotter and more perfect because it was so real).
His mind was spinning with a unique kind of jealousy, something that told him that he was sure if he wanted to steal you away from Hermione because he thought he could - because he now knew all of your sexual preferences and he would use that information to play you, to do everything she was doing to you and more. He would make you the perfect horny little puppet on his painful, throbbing cock (he gave himself another squeeze through his trousers, suppressing a moan of his own). He would have you calling him ‘Sir’ and begging for his cock in no time, because you needed it - you needed to have your holes filled and you would fucking love it.
Or if he wanted Hermione playing him like this - tugging on his hair, guiding him around by his tie like he was nothing more than a wretched dog, needing to be tamed. Wanted her using that bossy voice of hers to give him completely different kinds of orders - forcing him onto his knees to eat her cunt until she was satisfied, and - knowing her - she never would be.
Harry’s mind flashed with an image of him on his knees before you, his head so perfectly framed by your plush thighs, with Hermione behind him, barking orders in his ear, a tight grip on his hair as she shoved him tighter into your perfect, messy, wet pussy. He decided that was it - that was exactly what he wanted. That would be the vision that haunted his dreams from now on.
It was something that had him leaking enough precum to stain through to the outside of his pants, especially by the time your voice warbled out brokenly against Hermione’s chin, your thighs starting to shake, and Harry was sure that he would get the treat of seeing you cum on her fingers.
He was sorely disappointed by what happened next.
Hermione pulled back from you completely, creating another deadly wet sound as she pulled her fingers from your cunt once again - something that was almost drowned out by the pitched, disappointed whine that you let out.
“Mione-!” You complained sharply, the nickname almost coming out as a sob from the back of your throat.
You sat frozen on the edge of the desk, your legs spread wide as you stared Hermione down with glassy, disappointed eyes while she stepped back and grabbed a handkerchief from her bag that was sitting on a table opposite and used it to wipe off her glistening fingers.
Harry rushed to get a better look at your cunt before you closed your legs, and Merlin - it was magnificent. Swollen and puffed from Hermione’s efforts, coated in your wetness, your clit stuck out from the hood and standing at attention, so damn needy, begging to be touched, your hole slightly gaped from where Hermione’s fingers had been.
(Harry couldn’t help but to imagine how stretched you would be left by the thickness of his cock, how good you would look leaking with his cum…)
“What did you expect?” Hermione said sharply, the edge of a sarcastic laugh on her voice. She was firm, not giving in to the pout that you were giving her.
“You’ve been bratting up all day - I could have excused you flirting with Malfoy all through potions class-” She continued.
Harry had noticed that too. He had simply thought that Malfoy would be your next conquest, not a simple flirtation to get on Hermione’s nerves.
“If not for the fact that you didn’t finish any of your homework and you then decided to distract me from doing mine all afternoon.”
Of course. Hermione doling out sexual punishments for not doing homework.
Some things are just nature.
Though, Harry knew, if there was one thing that would motivate him to do his essays - it would be the idea of getting to cum.
“Of course you don’t get to cum, you stupid whore.” Hermione said these words how she said many things - as a final, finite declaration that was law.
Hearing her speak such filthy words in such an authoritative (and nearly emotionless) voice almost caused Harry to cum in his pants on the spot. Almost.
You let out a sigh of defeat and finally closed your legs, hopping off the desk and pulling down your skirt. Obviously, you hadn’t been wearing panties at all that day (which was another thought that would haunt Harry’s wet dreams) because you made no move to find a pair and put them back on. Instead, you simply turned around and gathered some of your books that were farther back on the desk.
“How long?” You asked Hermione tentatively, glancing over your shoulder at her.
Perhaps meaning - how long would she be angry with you? How long until she would finally allow you to cum?
Harry’s stomach lurched - he imagined himself finding you in the hallway and pinning you against the wall, flipping up your skirt and finding your still wet, bare cunt, teasing you with his fingers and promising to give you everything that you needed as long as you surrendered yourself to him. He would let you cum - he would make you cum so many times that you would cry and beg for him to stop. And he would leave you tired, satisfied and gaped with his cum dripping from all your pretty holes.
Perhaps it would be rude and underhanded to go after you simply based on a void that Hermione had left in you - but Harry was still feeling a bit of a petty sting from their argument the night before.
Hermione stepped toward you again - careful, calculated, like a predator observing its prey. She put her hands on either side of your waist, and leaned forward to whisper something in your ear that Harry barely caught.
“For as long as I want, naughty girl.” She told you. “You’ll take what you get, and you’ll like it, you understand me?”
“Yes, Mistress.” You sighed loyally in return. Though your face was knit with a unique displeasure - clearly, you were still aching to cum.
“And if I think for a moment that you have been touching your little whore cunt without my permission, I will spank you until every single person in Hogwarts hears you scream my name - understood?”
She topped this off with a sharp spank across your ass, using her free hand to hold the fabric of your skirt out of the way to make sure it was nothing but free, burning, skin on skin. You sucked in a sharp breath, and began nodding furiously.
“Yes, Mistress.”
“Good.” Hermione told you. “Now, off to bed.”
You began to walk off, but you hesitantly looked back over your shoulder, as if waiting for her to follow.
“I’ll be along in a few minutes. I have to sort out some more books for tomorrow. Since I now have so much to catch up on.” She added the last part with a bit of snark, and you rolled your eyes, turning around and walking.
Unfortunately, you abruptly headed in Harry’s direction and his stomach tightly clenched - he moved to press himself tightly into the bookcase, praying that you wouldn’t bump into him.
Perhaps you felt him move, or you simply felt something… off, but you paused for a moment, and stared harshly at the space where Harry was standing. His heart began to beat hard inside of his throat, and he wondered how fast he would be able to run with his cock so uncomfortably stiff inside of his pants. You kept staring, as though you were expecting something to materialise out of thin air.
“Y/N, go.” Hermione snapped. “Go on, it’s almost curfew.”
“Yes, Miss Prefect, I’m going.” You sighed sarcastically in return, and walked off.
Harry had a hard time not loudly gulping in air - not realising how harshly he had been holding his breath.
He stayed there for a few more minutes and continued to watch Hermione.
Jarringly, she was still so much of the usual Hermione. She was still absolutely someone that he knew so well, despite the secret sex persona that she had been hiding. Still biting at the skin around her nails as she concentrated on a thought, still fussing over which books to take, and still leaving the library with more of an armful than she could comfortably carry. Still somehow forgetting that she could just use magic to lug all the books to the Gryffindor common room instead of tiring out her arms - and Harry only fitfully realised now that this was only half her arm workout, and fucking your cunt raw must have been the other half.
The whole time he stood there, Harry had considered revealing himself to her.
He thought about begging to be let in on what the two of you had, even if he had to do something horrible to earn it first, to be worthy in her eyes - something like licking her shoes or wanking in front of her just to be ‘even’. But he knew that she would see the spying (even if unintentional) as a violation of trust, as something too creepy to be redeemed. She would probably hex him to hell and back, make him grow boils that would break open and bleed and never properly heal for the rest of his life - just for thinking about spying on her like that.
So Harry knew that he had to keep this whole thing a secret, keep it close to his chest. He could never, ever speak about it to anyone.
Harry forgot all about the book he had wanted. And, instead of going back to the Gryffindor common room behind Hermione, he took his aching cock to the Prefect’s Bathroom in an attempt to clear his mind. After making himself cum not once, but three different times, he finally settled into the hot water for a nice, long soak. He thought about it, and he realised that he was properly fucked - because he would never be able to look at you or Hermione in the same way again.

A/N: This is a oneshot, and at this current time, there is not going to be a continuation or a 'Part 2'. I might be open to writing a second part to this, but I don't have any current plans to do so and right now, it is not on my schedule. For now, if you are going to leave a comment on this fic, please leave a comment about the body of work that has been written instead of asking for more. If you want to see more Harry Potter fics that I have written, definitely check out my Harry Potter masterlist.
