...

The classroom was quiet, almost silent even if not for the slight sounds of pens being used to write down on paper as most of the students were focused on their work right now, their minds busy at work while it was slowly coming to the end of their afternoon classes. And as the other girls in her class were all writing with their heads down, concentrating fully on their sheets of paper Mikoto on the other hand didn't seem like she was as focused as all the other students were at the moment, biting her bottom lip a little the Railgun wanted to just get on with her work like everyone else was doing, but for some reason she felt like she couldn't.

She didn't exactly know why this was happening to her, she just knew that she was fine a few moments ago and now she suddenly felt...really warm, reaching her hand up to her forehead she wondered if she might be coming down with something, but her head was cool and she didn't feel all that ill to be honest. However this heat, whatever it was definitely seemed to be getting worse and worse by the second, her body seeming to be rising in temperature for no apparent reason, causing Mikoto to glance over to the teacher sitting at her desk and quietly going through her own paperwork.

Wondering if she should put her hand up and get the teacher's attention, since she figured maybe it would be best to ask to go the nurse's office, just in case this heat spreading throughout her entire body might mean she was getting sick or something, but also thinking that she should maybe just wait until the bell rang for lunch after all there wasn't much lesson time left. However before she could really decide just what she was going to do, she noticed something else about the way she was feeling right now, she could feel a sort of 'wanting desire' starting to rise up from deep within her core, causing her brown eyes to widened as she soon realised just what could be going on with her at this moment in time.

'Really...now of all times? I thought it was just getting a little too warm for me in here, but right now I can feel a strong urge to...well an urge to...'pleasure' myself I guess, but why now? I mean I know I haven't done it in a while...so maybe that's why I'm suddenly feeling like this,' Mikoto thought to herself, as she tried as she best as she could to ignore the feeling of her body obviously wanting a release at the moment, but it seemed like that strong urge was just getting more and more needy as time went on.

Biting down on her bottom lip harder the Railgun tried to just finish off the rest of her work, hoping to distract herself from the nagging desire that continued to grow from within her core and spread throughout her whole body, but that task proving to be one she was clearly not succeeding at, as she could soon feel a warm and wet sensation beginning to dampen her underwear.

Letting herself lean forward over her desk and tightly pressing both of her fists in-between her legs, praying that the slight friction of her underwear being rubbed against her aroused sex would be enough to satisfy her for now, but that not seeming to be the case unfortunately as her body was still begging for a release of some sort, her cheeks being stained with a deep blush. As she wasn't sure how long she could keep going like this, before she would no longer be able to fight against the strong desire that was continuing to become harder for her to ignore.

Looking to the ticking clock on the wall and hoping that it would go faster, closing her eyes tightly and gritting her teeth together as she had basically just given up on trying to finish her work, after all it was pretty obvious that these feelings of desire weren't going to go away anytime soon, meaning that she would have to try and wait for lunch before 'dealing' with this inconvenient problem of hers. Luckily enough however it wasn't long before the bell for lunch break finally rang, singling for the students to quickly grab their things and leave their classrooms, before heading off to the lunch hall and while that is exactly what most of the girls from Mikoto's class did. She on the other hand just gave out a sigh of relief, as she honestly wasn't sure just how much longer she would have lasted while trying to ignore the urge to just go and satisfy her needs.

The Railgun quickly getting her stuff together as she stood to leave and head for the girls' bathroom, knowing that there was no way she could keep ignoring what her body was constantly begging her for right now. Meanwhile unknown to Mikoto 'The Queen of the school' had also not left the classroom along with everyone else, instead just telling all the girls that usually hang around her to save her a seat in the lunch hall, leaving Misaki to watch her rival level 5 leave with a smirk currently forming on her lips.

...

Letting a deep sigh leave her lips Mikoto had made her way into the girls' toilets, currently sitting on the floor in the farthest toilet stall, as she tried to slow down both her breathing and the pace of her racing heart at the moment, resting her head in her hands while she could still feel her desire growing and her body pleading for a release.

'I know I shouldn't be doing this sort of thing in school, after all what if someone walks in and hears me? But...no matter how much I try to ignore this feeling...it just won't go away, and there's no way I can make it to my dorm and back before lunch break ends. So...doing this here...it seems like it's my only option right now,' Finally deciding to just give into what her body was begging her for, hoping to deal with this issue of hers quickly so that she would still have time to grab something for her lunch, before having to make her way to her next class once the bell had rung once again.

'Okay...just stay quiet,' She thought to herself as she took a deep breath, and made sure she couldn't hear anyone entering the girls' toilets, before she slowly slipped her hand underneath her skirt, shorts and underwear. Gasping and quickly covering her mouth with her free hand as she caressed her aroused slit, feeling just how wet she was already and bit back a couple of moans, while she started to slowly pleasure herself and finally giving her body what it had been craving for all this time.

Meanwhile Misaki had now left the classroom after all the other students had, as she had followed Mikoto into the girls' bathroom, but made sure to be extra quiet when opening and closing the door, since she didn't want the other girl hearing her. Slowly going into the stall beside the one that she assumed Mikoto would be in, since it was the only one that was closed at the moment, silently closing and locking the stall door behind her, before she climbed onto the toilet tank and peeked over the top.

A wide sly smile making its way across her lips, the blonde looking down and being delighted to see the Railgun in a very vulnerable position right now, raising her eyebrow slightly as she watched her rival pleasuring herself on the floor and soon took her phone out of her pocket, turning on her video camera before she lifted it up a little and simply pressed record.

Mikoto not seeming to be aware of the other girl at all as she was currently facing away from her direction, and was clearly more focused on making her nagging feeling of desire go away at this moment in time, while she closed her eyes and pressed her hand harder against her lips, muffling out her moans as she continued to stroke her soaked slit.

'I can't believe I'm actually doing this sort of thing here...honestly I don't think even Kuroko would do something this perverted. But...I can't help it...this feeling won't go away and I need a release. So...getting this over and done with now is the best thing I can do...right?' Questioning herself Mikoto couldn't help but think just what could happen if somehow she was found out, but then also not being able to stop at the moment, after all her body was finally starting to feel like it was getting the satisfaction it had needed, so she simply just shook her head and decided to focus on dealing with this problem of hers quickly before any other girls entered the restroom.

The Railgun still not seeming to have noticed the blonde watching her at the moment, as she continued to increase her pace and eventually started to thrust two fingers deeply inside her covered entrance, not really minding the fact that she was currently causing her underwear to become soaked with her lewd juices, guessing that she would have to change them anyway since they were already wet before she came into the girls' toilets earlier.

Being glad that she always chose to wear shorts over her underwear, meaning that she could easily discard her damp panties into her school bag for now, and just wear her shorts under her skirt until she could change later once she was back in the safety of her dorm room again. Mikoto continuing to double her efforts and bite back pleasure-filled moans as she could soon feel her walls tightening around her two fingers, clamping down on them and also feeling pressure quickly building up inside her lower abdomen, it now becoming all too clear just how close she was to reaching her limit.

While Misaki just smirked at seeing her rival squirm and struggle to keep herself quiet, as it was obvious that she wouldn't be able to hold her climax back for much longer, so the blonde simply just stopped recording and silently put her phone back into her pocket, deciding that she might as well leave now before Mikoto had the chance to notice she was there. Leaving the girls' toilets as quickly and as quietly as she could, although probably not needing to since the Railgun was getting so caught up in making herself cum, it was pretty much the only thing she was focusing on at the moment.

It only taking a few more mere minutes before the powerful electromaster was moaning into her hand, squirming and shaking all over as her long awaited orgasm rippled through her body, and soon caused her to collapse against the wall of the toilet stall, panting heavily and finally feeling satisfied it would seem. Removing her hand from underneath her skirt as she sighed and waited for her breathing to go back to normal, before she quickly cleaned herself up and stuffed her wet underwear into her bag, leaving the stall and walking over to the mirrors to check how she looked.

Fixing her clothing and hair and splashing her face with cold water a couple of times, her cheeks still being stained with a deep red blush, while she rested her head against the mirror and closed her eyes. Calming and collecting herself, before she just gave her hands a quick wash and soon left the girls' toilets, going off to the lunch hall as she hoped she could get her mind off of what had just happened and get something to eat, knowing that the bell would ring for classes to start back again if she wasn't quick enough.

...

The next day Mikoto felt like throwing herself into her studies as to hopefully keep her mind off of what had happened the day before, spending her time in the school library once all her lessons had ended, as she now sat at one of the small tables on the library's first floor, reading through her study books and trying to concentrate as best as she could. However that not seeming to last all that long as she soon let out a heavy sigh, when that embarrassing event yesterday started to sneak its way into the front of her mind once again.

'I still can't believe I actually did something like at while I was still at school, I mean I don't even do that sort of thing very often. Maybe I could have just continued to bear with it and wait until I was back in my dorm again...but why did I suddenly feel the need to do it anyway? After all nothing like that has ever happened to me before...so...' She soon was being brought out of her thoughts as well as her studies, as she heard a familiar voice call out her name, causing her to have her attention taken off her study books in front of her, and instead look up to see the smirking face of 'The Queen of the school' looking back to her unexpectedly.

"Misaka, I thought I might find you here,"

The blonde seeming oddly glad to see the Railgun and causing her to grimace a little as she knew the other level 5 only ever talked to her to mostly just screw around with her, and she expected this time to be no different, as she just propped herself up on her elbow and raised her eyebrow back to Misaki.

"Do you need something, Shokuhou?"

Misaki simply just widening her smirk as she came to sit down beside Mikoto at the table, but not really answering the other girl as she just took out her mobile phone from her pocket, and placed it down on to the table in front of them both.

"No not really, I was just wondering if I could spare a few minutes of your time as all,"

"Okay, but where are those girls that are always following you around?"

"I thought it would be best for us to talk alone, so they're all busy studying,"

'Just like I was before you came over here to interrupt me,' Mikoto felt like saying in reply, but decided to just stay quiet, since it was obvious that the blonde apparently wasn't done explaining exactly why she had come over to talk to the Railgun just yet.

"Anyway I stumbled upon something quite...'interesting' yesterday, and I thought I'd share it with you before anyone else sees it, so please feel free to take a look and tell me what you think," Misaki explained as she opened up a video on her phone, while causing the other level 5 to just look a little confused, wondering why the blonde seemed to be acting so strange right now and questioning whether she should be suspicious or not at the moment.

"Okay..."

The Railgun looking to the phone's screen as she wondered just what the blonde seemed so eager for her to see, guessing that Misaki was most likely doing this to just wind her up, as was per usual. Just rolling her eyes a little and guessing she might as well look to see just what the other girl had found so 'interesting' as she called it, watching as Misaki pressed the play button on the video and simply sat back, waiting to see what reaction she would get from her rival.

Unsure of what exactly to expect Mikoto looked to the video with a curious expression, however that quickly changing to a more shocked one as she saw that the video was of her, and not just that but it was of her pleasuring herself in the girls' toilets yesterday, her eyes going wide and her face flushing as she took the phone out of Misaki's hand so that she could see just what was going on in the video better. The blonde just smirking as she was already amused by the other girl's reaction, and was just waiting to see what the brunette would say in response to seeing that not only had Misaki seen what she did yesterday, but she had also filmed it all.

'H-how...how did she see me? I made sure that no one else was in the restroom both when I entered and left and I didn't hear anyone walk in nor out the whole time that I was in there, so then how did she film this without me even knowing she was there?' Mikoto looking at the video with a shocked expression, seeming a bit speechless at the moment, while Misaki was just enjoying watching the other girl's panicked reaction, as she leaned forward and was going to press the button on the side of her phone to turn the volume up. However her hand was quickly stopped from doing so when the brunette paused the video and placed the phone face down on the table, hiding what was on the screen from anyone else that happened to walk past them right now.

"How...how did you know about this?" Still seeming to be in shock by what she had seen, Mikoto looked back to the blonde sitting next to her, while Misaki simply just shrugged her shoulders and leaned closer to her rival with a wide smirk spreading across her lips.

"Well I guess it was because I had a part to play in it all,"

"What do you mean?"

"Didn't you notice? Yesterday that annoying EM barrier of yours was down; I imagine it was because of everything that happened after the whole 'Level 6 shift' incident. I thought your power might be weaker after all that so I tried out my tampering powers on you, and they actually worked for once," Misaki's explanation causing Mikoto to widen her eyes as she hadn't even realised her EM barrier had been down all day yesterday until now, thinking back on the day before and remembering all that had led up to her ending up pleasuring herself in the girls' toilets, but was still a little unsure of just where the blonde was going with what she was saying, and so just waited for her to explain what she had done in more detail.

"I mean I was only trying to see if I could use my power on you, and although I couldn't do much it certainly was quite surprising to see the effect it had on your body. But I guess it does make sense that I couldn't do much, after all your body is always creating that magnetic field around you, so I guess it would interfere with my tampering powers. Meaning that the only thing I could really do was cause your body temperature to rise higher and higher until you couldn't take it anymore, and when you rushed off to the bathroom I decided to follow you. I stayed quiet so you wouldn't hear me and while you did look hot and bothered when you left the classroom, I certainly didn't expect to see you doing 'that' kind of thing-

"Wait...you made me do all of that stuff yesterday?" The blonde being cut off by the Railgun as things now started to make sense in her mind, making her realise what she ended up doing yesterday wasn't just a weird happenstance and instead Misaki was the one that had caused it all.

"Well I only made you feel a little warm; your body was the one that had such a lewd reaction to it, honestly who knew the great 'Ace' of our school could do something so perverted. And I wonder how our fellow students would react if I showed them this video," Raising her eyebrow Misaki knew she was getting the other girl all wound up right now, and waited to see just what kind of reaction she would get out of Mikoto, as before long her collar was being grabbed by her blushing rival.

"Delete it now, or I swear I will fry you to a crisp," She warned in a stern tone, her expression now full of anger as she was ready to shock that smug smirk right off the blonde girl's face, while Misaki seemed completely unfazed by the Railgun's threat as it was pretty much exactly what she was expecting, simply just taking hold of Mikoto's wrists and encouraged her to let go of her collar.

"Now, now there's no need to get violent, you don't want to make a scene in front of everyone here right? If you want me to delete this video and not show it to anyone else, then that's what I will do," Misaki stated as she caused Mikoto to look back to her with a questioning expression, as she didn't expect the other girl to be so reasonable and willing to do as she wished, but she thought there had to be some catch and it turns out that she was right.

"But in return-

"Here we go, what do you want?"

The brunette asked as she had let go of the other girl's collar and just folded her arms, waiting to see what she would have to do in return for the blonde to delete that video of her, knowing that when it came to Misaki Shokuhou whatever she would have to do, it wouldn't be anything good.

"Pick up all your study books and come with me,"

The blonde simply made a gesture with her hand for the other girl to follow her, that same smug smirk still resting on her lips as they both stood up from their chairs, Misaki grabbing her phone from the table. Mikoto doing the same with all her study books before she was led into the back corner of the library, where there were only a few other students studying or talking with one another, the two level 5s sitting down at a small corner desk while the brunette was still wondering just what the other was planning at this moment.

"Alright, now get under the table,"

"What why?"

Mikoto looking confused as she didn't know what she was expecting Misaki to demand of her, but she knew it definitely wasn't the other girl telling her to 'get under the table' for some random reason it would seem.

"Do you want me to delete the video or not?"

Folding her arms and raising her eyebrow Misaki waited to see if the other girl would actually do as she had requested of her without asking anymore questions, and it seemed like Mikoto just wanted to get whatever this was over and done with, sighing deeply before nodding her head and doing as she was told.

"Fine,"

She replied in an annoyed tone as she just glanced around to make sure none of the other girls where looking their way, before she crouched down under the desk and waited for her next instruction, wondering just where this seemingly weird situation was going right now.

"Good, now come closer to me," The blonde curling her index finger in a 'come here' gesture, causing Mikoto to just roll her eyes as she soon reluctantly did as she was told, now sitting crouched in front of Misaki's legs, her face being level and quite close to her rival's knees.

"Now what?"

"Now simply do whatever feels natural to you," Another sly smirk spreading across Misaki's lips as she parted her legs wide and lifted up her school skirt a little, just enough for the brunette to catch a quick glimpse of the dark purple panties she was currently wearing underneath.

"Just what are you insinuating for me to do right now?" Mikoto asked raising her eyebrow a little and looking confused, while the blonde simply just sat back in her chair and wiggled her hips in front of the Railgun, so that she could get a better look at her underwear.

"Well isn't it obvious? Yesterday when I filmed the video of you touching yourself, I will admit that it also turned me on a little, I tried to deal with it myself when I go back to my dorm, but for some reason I just couldn't be satisfied enough," Continuing to tease Mikoto the blonde pouted slightly down to her, causing the Railgun to just stare blankly back up to her, before Misaki pushed herself a little far forward on her chair, resulting in the brunette now sitting in-between her legs and starting to blush slightly when she realised just how close she was to the other girl's immediate area.

"So...?"

"So I caused you to get all hot and bothered, and in return you do the same to me, plus you can 'pleasure' me in any way you see fit. That sounds fair right?" Misaki now lifting her school skirt up more so that Mikoto could clearly see her uncovered underwear, the other girl just shaking her head and turning away from the blonde, a slight blush starting to stain her cheeks, while causing Misaki to raise her eyebrow with another smirk.

"No, there's no way that I'm doing that sort of thing,"

"Is that so? You see Misaka all I have to do is press this one little button and this lewd video of you finger fucking yourself will be sent to practically everyone in our school, would you rather I do that instead of deleting the video like you asked me to do earlier?" Taking her mobile phone out of her pocket and pointing to the 'send' button on it, Misaki was clearly showing the Railgun that she wasn't bluffing right now, and although Mikoto did look back to the blonde slightly, it was obvious that she wasn't giving in just yet.

"If you dare I can just report you, I know people who are with Judgement and last time I checked, filming someone without their consent is a serious crime," The brunette stated as she tried to not let Misaki get to her, knowing that she couldn't back down right now and would just have to fight back, even though it seemed like the cunning blonde could easily find a loophole for herself in every threat that Mikoto made against her.

"Go ahead and try it by all means, but with my tampering powers it's not like I couldn't get out of any trouble easily enough, and if you try to shock me then I can just get all the girls in here to fight for me. You can't fight them all off at once and I doubt you would actually want to harm anyone who's innocent right?" Sitting back in her chair again and folding her arms across her chest, Misaki was almost sure that she had won already, it being only a matter of short time before the Railgun would cave and go through with what the blonde had told her.

'It doesn't matter what I say she can find a way of getting out of all the threats I make, it's like she knows what I'm going to say next, and easily has a way of making things work out in her favour and certainly not mine. I hate to admit it and give in, but it seems like that's the only option I've got if I want that video of me to be deleted...just how did I let myself get caught up in all this?' Letting a long sigh leave her lips Mikoto no longer saw any way out of this, then to just do as the blonde had said to get it all over with, and have that embarrassing video of her deleted. Turning back to Misaki and nodding to herself the Railgun gave a glare to the girl smirking down to her and finally surrendered, as she figured there were worse things that her rival could have blackmailed her into doing, things that could result in much more dire consequences then just the possibility of them being seen and having a few rumours being spread around the school, which most of the students likely wouldn't believe anyway.

"Fine...I'll do it,"

The Railgun speaking in a low toned voice as she pushed herself back a little, while Misaki just smiled at her plan working, letting herself relax and closing her eyes, wondering just how her rival was going to pleasure her, if she actually did go through with it like she had just said she would that is. However the blonde soon being a bit confused when she felt Mikoto's warm hands slowly taking off both her shoes and socks, slipping them off her feet and throwing them behind her for the time being, causing Misaki to pull her now exposed feet away from the Railgun, and had an questioning expression when Mikoto glanced back up to her a moment later.

"Why did you just take my shoes and socks off, do you have some kind of foot fetish that I didn't know about?" The blonde teased while also being half serious, as she started to wonder just what the Railgun was planning on doing, since she hadn't expected her to go for her feet first. But Mikoto not really answering her as she just glared back up to her, blushing deeply before she just focused on what she was doing right now, and trying not to listen to the annoying girl who had gotten her into this mess.

"Just shut up will you,"

She mumbled out and rolled her eyes, as she leaned down to the blonde's bare foot and surprisingly causing Misaki to shiver against her warm breath, before she just lightly kissed the girl's soft skin, licking the tip on her toes a couple of times first, and dragging hot tongue along her foot. Before she began to shower every part of Misaki's right foot in light pecks and licks, giving the same treatment to her left one soon afterwards, the blonde still looking a little confused as she never imagined her rival would actually be kissing her feet. But just soon shrugging her shoulders as she tried to keep herself from shivering too much, at the feeling of the Railgun's lips constantly pressing against her skin.

'I can't believe I'm actually doing this right now. I thought I could just stick to her legs and feet since she probably didn't expect me to do something like this to her, but...just how far should I go? Do I actually have to...'pleasure' her at some point like she said earlier?' Mikoto questioned inside her mind, feeling glad no one could see her right now, as she slowly trailed her tongue up Misaki's leg. Starting from her ankle and stopping just below her knee, pausing to go back every so often to lie small kisses and licks on any part of the blonde's leg she had missed, before switching over to the other leg and giving that one the exact same treatment, licking all around the area below her knee as she was well and truly causing Misaki's legs to become soaked in her warm saliva.

"You know...I don't like to admit it, but I'm actually starting to enjoy this, I mean really just where did you learn this from Misaka?"

Misaki already feeling her body heat rising and her desires reacting to the light kisses, and long licks she was currently getting from the girl that sat in-between her legs at this moment. Mikoto on the other hand just looking back up to the blonde with a blank gaze, trailing her hot tongue over her knee, swirling her tongue right in the centre of her kneecap and covering more of Misaki's skin in her saliva, lying one small last kiss above her left knee before she swallowed and stopped for a second.

"Just stop talking already, before someone hears you,"

She simply replied in a cold tone, causing Misaki to just nod and wink back to her, deciding she would have to keep relatively quiet since she was actually finding that she didn't want the Railgun to stop at all, in fact she wanted nothing more than for her to continue what she was currently doing to her. Mikoto just sighing at that annoying wink as she was soon covering the blonde's thighs in thousands of little kisses, and trailing her tongue along them one at a time, going from the area just above her knee and slowly licking her way towards her waist, before stopping when she came to those dark purple panties that were now right in front of her eyes.

'I know I was just planning on going as far as her feet and legs and that would be it. But somehow...I don't want to stop...I must just be getting caught up in the moment, after all there's no way that I could actually like doing something like this to her...right?' Seeming like she was trying to convince herself more than anything at the moment, Mikoto soon just shook her head and chose not to focus on her thoughts, as she instead just went with her desires and lightly licked Misaki's covered sex, dragging her hot tongue along it slowly and causing the blonde to widen her eyes in surprise.

A gasp escaping her lips before she quickly covered her mouth with both hands, looking down to Mikoto with an all too shocked expression, while the brunette simply just continued to lick her covered privates, causing the blonde to squirm and start to feel a wet sensation dampening her underwear. Misaki clearly not expecting the Railgun to actually start pleasuring her so suddenly, as it didn't seem to faze Mikoto much at all, as she simply just rolled up Misaki's skirt and slowly pulled down her panties, noticing how they were already quite damp when she slipped the other girl's feet out of them and threw them over her shoulder.

The blonde feeling like she should say something to the Railgun, hearing herself panting heavily and starting to let out quiet moans into her hands, but before she got the chance to even try and form a single word, the brunette caught her attention and had stopped her assault for now it seemed.

"Hey Shokuhou...I know this is a bit personal, but...are you a virgin by any chance?"

Mikoto really just wanting to know mostly for the fact that she didn't want to be too rough on the other girl, even if she was her rival. Looking up to the blonde with a curious expression she patiently waited for an answer, while Misaki seemed surprised by her question, definitely not expecting her to ask her anything like that at all, but guessing she should answer since it didn't look like the Railgun was going to continue unless she got a reply from her.

Definitely not wanting the brunette to stop since her body was now begging for more attention, and she most certainly didn't want to be left feeling unsatisfied, the blonde calmed her thoughts a bit and took a deep breath. 'Well I've haven't gone all the way with anyone just yet, if that's what you mean,' she wanted to say, but instead just nodded her head in response, feeling like if she tried to say anything she would just end up moaning too much, since she could still very much feel Mikoto's hot breath on her exposed sex at the moment.

"Then I'll be gentle, and it's probably better for me to use my tongue and not my fingers on you,"

Seeming to be thinking out loud more than anything else right now, Mikoto just sighed slightly and caused Misaki to wonder why she seemed to care about hurting her when she had blackmailed her into doing this in the first place, feeling like she should question the brunette but not getting the chance to as before she knew it she had to cover her mouth once again.

Pressing one palm against her lips and resting the other on top of Mikoto's head, as she pushed her away slightly as soon as she felt the Railgun give her aroused slit a long lick, making Mikoto stop what she was doing and look back up to Misaki with a questioning expression, obviously wondering why she had just stopped her from continuing.

"Misaka...don't do that so suddenly...I can't hold back my voice if you go that fast,"

The panting blonde moaned in-between her words, pleading for the Railgun to go slower so that she wouldn't have to struggle as much to keep herself quiet, but it seemed like Mikoto didn't care very much about the other girls in the library hearing Misaki, since she simply just shrugged her shoulders and licked her lips in response.

"Then...just try to not moan so much,"

Was her simple reply as she ignored the hand pushing down on her head and continued with her advances, giving the other girl's soaked slit another few long licks, making them slower as she went on, starting from the very bottom of her aroused folds and ending at the tip of the blonde's clit. Soon wrapping her lips around Misaki's entrance, beginning to suck gently and causing her to bite down onto her bottom lip in order to not moan loudly in result. While Mikoto suckled softly at first but then did it harder and harder, as she would take a deep breath in and put as much force as she could to suck roughly on the blonde's lower lips, before she breathed out again, repeating this cycle for quite a while it seemed.

'To be honest...I feel like I can't stop right now...am I actually starting to like this?' Mikoto wondered to herself as she sighed into the blonde's drenched entrance causing it to overflow with her erotic juices; however the brunette simply just choosing to keep her lips locked around Misaki's sex, not wanting to get any of said juices on her school uniform after all. Glancing up to her rival the Railgun was surprised to see her panting, squirming and moaning into her palm as she was now pushing Mikoto closer to her, obviously showing that she wanted more from her.

'She definitely looks like she's enjoying this though...I didn't know she could make such a face before now and I...I kind of want to hear her moan more,' Increasing her speed a little Mikoto began to thrust her tongue deeply inside the blonde's slit, causing Misaki to let a few moans escape her lips, not being able to bite them all back, trying as best as she could to stay quiet at the moment but it seeming to be getting harder and harder as time went on. The brunette simply just letting her mind go blank and she knew this was crazy right now, but she didn't care about that, all she cared about was making the other girl moan and react more to her actions.

"Mmm...Misaka...mmm..." Muffling all her moans as best as she could Misaki felt her desire continuing to grow from deep within her core, knowing that it wouldn't be very long before the familiar feeling of pressure would start to quickly build up inside her lower abdomen.

However the blonde soon being distracted from the moment at hand as her ears caught the sound of slight whispers coming from behind her, turning her head a little Misaki now saw two girls sitting at the table behind her, noticing that they were whispering to each other and blushing, as well as looking down to see the Railgun under the desk. The two girls being the only two close enough to see what was happening, so it was no wonder they were not only astonished by what they were seeing, but also very interested to keep watching it all at this moment.

Misaki guessing they must of heard her slight moans and realised what was going on when they saw Mikoto under the table, blushing deeply as she was a little embarrassed about them being found out, but it seemed like the Railgun hadn't noticed just yet, and so the blonde just simply smiled and turned her head to face the two girls. Catching their attention when she cleared her throat and caused them both to look to her instead of the girl giving her pleasure under the desk right now, placing a single finger over her lips in a 'keep quiet about this' gesture, as she winked to them both and they just nodded quickly in response, pretending like they weren't watching but sneakily glancing back down at Mikoto every now and again.

"You know...if you keep going like this for much longer...I won't be able to hold back,"

The blonde whispered to Mikoto as she tugged on her short brown hair a little, clearly feeling that pressure now beginning to build up fast, however the Railgun not seeming to care yet again, as she simply just glanced back up to Misaki and shrugged her shoulders as if to say, 'Then don't hold back,' in reply. The brunette keeping her brown eyes locked on her panting rival, as she moved her hands from where they had been resting all this time on Misaki's thighs, keeping her legs spread widely and instead now reaching up to slip her hands under the blonde's shirt and running her fingers along her lower back slowly, causing Misaki to tremble uncontrollably and clench her teeth together tightly.

Feeling the Railgun double her efforts Misaki rested both of her hands on top of Mikoto's head, pushing her further so that her nose was actually touching her swollen clit, rubbing against it slightly while her voice was quickly getting louder and louder, no longer being able to muffle it at all as she honestly just felt like she wanted to scream right now.

Using her hands to keep the squirming blonde in place Mikoto held tightly onto the other girl's lower back, caressing her skin softly and making her shiver all over, while she could soon feel Misaki's walls tightening and starting to clamp down on her tongue. Knowing just how close her rival was, Mikoto thrusted her tongue as deep as it would go inside of her, doubling her efforts yet again and taking a deep breath in as she was finally able to push Misaki over the edge, soon tasting a salty yet sweet liquid that was a little thicker than water beginning to squirt into her mouth and slip down her throat.

'She's cumming...there so much of it coating my throat...but if I get any on my uniform the other girls might notice. I guess I'll just have to bare with it and swallow it all,' She thought with a heavy sigh, pacing herself as she practically drank all of Misaki's juices a moment later, mouthful by mouthful, gulping it all down like she was dying of thirst and continuing to keep her lips locked around the blonde's overflowing sex. Causing Misaki to ride out her orgasm, while she felt wave after wave of intense pleasure rippling throughout her entire body, her mind going completely blank and her heart pounding wildly inside her chest, as a loud scream of release escaped from her open mouth.

"AAAAHHHHHHHHHH!"

As soon as it had left her lips Misaki regretted it, knowing that it had likely caught the attention of pretty much every girl in their area at the moment, causing the blonde to nervously smile at all the staring eyes that were now on her, clearly wondering why she had screamed so loudly and so suddenly.

"S-sorry...I err...I bit my tongue,"

She stated with an embarrassed blush covering her cheeks, giving out a nervous laugh, as it luckily seemed like most of the girls had brought the lie and simply went back to doing whatever they were doing a moment ago. However when Misaki looked to see the two girls behind her she now saw the both of them were staring straight at her and Mikoto, clearly being surprised at what they had just seen and unsure of how to react, as they just continued to watch intently, while the blonde rode out the last of her overwhelming orgasm.

Not quite believing that Mikoto was still gulping down every single drop of her cum, giving the Railgun an impressed expression as she covered her mouth back up with one hand, riding out the last of her climax and being surprised that she was still cumming after what was definitely more than several minutes. Curling her toes, throwing her head back in sheer ecstasy, and tensing up every one of her muscles. Before finally she collapsed back on to her chair and started to come down from her high, relaxing her hand on top of Mikoto's head as she just ran her fingers through her short brown hair gently, while she looked down to the Railgun, watching her sit back and open her mouth slightly a moment later to pant heavily and catch her breath.

Golden eyes widening as Misaki saw the last of her clear erotic juices covering Mikoto's tongue and gums, guessing that it must have been her final load of cum that she had just squirted into the brunette's mouth, causing her to blush deeply and bite her bottom lip, watching as the other girl simply swallowed that last mouthful and licked her lips clean.

Now letting go of Misaki and sighing heavily, silently just slipping the blonde's still damp panties back on her, with her socks and shoes following suit, before the Railgun soon came up from under the table and sat down in her chair beside her rival. Misaki just now getting her breathing back to normal, as she sighed and smirked back to the girl sitting next to her.

"Well that certainly was surprising, just where did you learn to be so good at going down on someone? I mean seriously I didn't expect you to go as far as chugging down all of my cum like it was some addicting drink. I honestly don't think I've ever cum that much in my life, and...correct me if I'm wrong but I think you were actually enjoying it just as much as I was," she teased, causing Mikoto to just roll her eyes and turn away from the blonde, while a deep blush was still staining her cheeks.

"You are wrong, I was just trying to get it over and done with quickly, and I hated every second of it,"

"Oh really? Then if the situation ever called for it, would you consider doing something like that to me again in the future?" Raising her eyebrow Misaki widened her smirk, waiting to hear the Railgun's answer and being a little taken aback to see that it took Mikoto a little while to reply, as it seemed like she was actually thinking about that question for a few minutes, before finally responding.

"O-of course not,"

"Then why did you just hesitate for so long?"

"I didn't!"

The brunette raising her tone a little, only to regret doing so as a teacher who was walking past told her to 'Shh', and gave her a scolding look, while Mikoto smiled nervously back to her and apologised. Before she now finally noticed the two girls sitting behind them seeing them staring at her and whispering to each other, causing her to blush in embarrassment as she guessed they must have seen everything that she had just done to the blonde girl sitting beside her. Misaki noticing the worried expression on the other girl's face, and saw that she was now looking to the two girls that had been sitting behind them this whole time, resting her hand on Mikoto's shoulder and giving her a reassuring smile.

"Don't worry I'll erase their memories later," She stated with a wink, causing the Railgun to just roll her eyes yet again and fold her arms across her chest, turning back around on her chair, before she just changed the subject to what was clearly in the forefront of her mind right now.

"Now delete that video of me,"

She demanded with a glare, resulting in Misaki just simply nodding her head and taking out her phone from her pocket, showing the other girl the screen as she found the embarrassing video of Mikoto and let the Railgun watch as she pressed the 'delete' button, before just smiling back to her rival.

"And...It's gone, happy?"

"Delighted, now...just leave me in peace already will you," The brunette lowered her tone still glaring to Misaki, as she simply just nodded and stood up from her chair a moment later.

"As you wish Misaka, I guess you need some time to process everything you just did to me after all,"

The blonde replied as she knew she would likely be doing the same later, knowing that both of them would be thinking about what had just happened between them for a good while. Leaving Mikoto alone and getting the attention of the other two girls sitting at the table behind them, gesturing for them to follow her, while the Railgun just sighed deeply.

"Yeah, you got that right... but maybe I really did enjoy doing all that...just a little bit," Mikoto whispered under her breath as she blushed a little, and clearly had a lot to think about to herself, while Misaki took the other two girls out of the library and into the school hallway instead.

"Listen I could easily just erase your memories so that you forget everything you just saw, but I'm feeling pretty exhausted after everything that just happened in there, so I will let you keep your memories of this day. But only if you both promise not to tell anyone, and I mean anyone what you just saw got it?" The blonde warned, causing the other two girls to just nod quickly, and say 'we promise' in reply, definitely not wanting their memories to get erased and knowing to stay quiet since they really didn't want to get on to Misaki's bad side, she is the 'Queen of the school' after all.

"We got it...but may I ask why you two were doing something like that in public?" One of the girls asked in a very interested tone.

"Are you two secretly dating or something?" The other girl added with the same intrigued expression, them both clearly looking for more information, while Misaki just smirked and shook her head simply in reply.

"No, that's not it at all. You see...we were simply exploring the benefits and joys of blackmail and absolute pleasure,"

She stated causing the other two girls to not really understand what exactly she had meant, but that seeming like the best answer they were going to get out of the blonde, as she winked to them both before turning and heading back into the library, wondering if Mikoto was having the same thought as she was at this very moment in time.

'You know, I honestly think I really wouldn't mind maybe doing something like that again...someday at least.' That thought being a shared one between the two level 5s, as they both would certainly need a little more time to fully process just what had happened between them only a few moments ago, while they were in the silence of the school library together.
