AN EASY A - NAGI SEISHIRO

synopsis: There's a problem student in your class and he just can't seem to understand that he needs to put in the effort. You've already given him three chances to make up his assignments - all of which he ignored. But what happens when he suggests another alternative during office hours?

There are some habits that never seem to change — even with age. You’ve seen it all, experienced it too, from emailing your teachers last minute about having to make up an exam worth over half of your course grade to faking a family death in order to get an extension, or — and this is more for students who are a bit too ‘brave’ — blaming the teachers for their inability to do their jobs. You knew what you would be getting into when you went into this job, from having to do the last minute panic pleas to now being on the receiving end of it. And you now actually feel sorry for having to bombard your past professors like that.

You release a deep breath from your nose and flick the red gel pen across a student’s exam, circling the large failing number by their name. “I’ll see you next year.” You try to sound less harsh, more on the sympathetic side, since you’re relatively still within the same age group as some of these students, but who wants to hear that? That they have to repeat a course and be stuck a graduation year behind? Absolutely no one.

You want to look away as you hand the student back his exam scores because you just know it’s going to end with tears and meaningless pleas but that would be unprofessional on your end. Instead, you give the student a small smile and a couple of pieces of candy from the glass bowl next to you.

“Sorry if it’s not much but it’s better than nothing?” God, you need to work on your pep talk. These students are basically adults, not elementary school kids.

“A-Are you sure I can’t do anything else to boost my grade?” The student starts to whimper and you have to tense your whole body from cringing at their quivering voice.

Ugh, it’s useless. Why bother begging if they haven’t bothered to study the material?

Still, you manage to whip up an emphatic frown and shake your head, voice sounding more motherly. “I’m sure it’ll be easier for you to understand next time.”

Another whine and then a final huff before the student storms out of your office. By the time the door shuts and their wails are out of ear shot, you slump back into your chair and groan loudly into your palms. Your body aches from being at your desk all day long — your mind is doing no better, having to deal with students’ cries and unwarranted trauma dumping. Seriously, when are they going to pay teachers more to deal with this type of stuff?

On the bright side of things, your office hours are officially over. Final grades will be up by tonight and you’ve completed most of your tasks with all but one student being a constant no show for the eternity of the semester but that responsibility doesn’t fall onto you. He and the handful of others can just show up again next year.

You spend some time debating your options, eating a nice, warm bowl of noodles sounds good for now but… you did spend nearly eight hours cooped up in your office and you are feeling a bit high energy right now, so stress relieving might be a good answer first.

��Now, where did I put that thing?” You reach down your desk, pulling up your purse and rummage through it looking for a very specific purple ‘massager’.

It’s super rare for you to ‘release’ stress while on campus grounds, this might be one of the few times, with others following the same patterns, but you feel the utter need to reward yourself after today’s events. It’ll only take you maybe ten minutes max, afterwards it’s dinner and then a quiet train ride home. Plus, not like you have a partner who can do this for you — you barely have time to take care of yourself, let alone be in a relationship or commit yourself to a random hook up. Sometimes, it’s just better to handle the situation yourself since it is your body.

A breathy sigh leaves your lips as you place the vibrating head against the soft cotton fabric of your panties, already soaked through by just the thought of de-stressing yourself. You throw your head back, with one hand steady with the magic wand and the other traveling up to your blouse, unbuttoning the top and allowing your black bra to be exposed in the room. As you increase the pressure from the vibrations, your free hand spills your breasts from its cups, your thumbs and digits immediately running over the sensitive nubs and plush flesh of your chest as you start to chase your high.

“M-Mhm—! Right there…” You roll your head to the side and shut your eyes, imagination fleeting to the thoughts of a male seated in between your legs, his tongue desperate and latching to your overwhelmed clit and folds while your thighs keep his shoulders in place.

You think it’s so unfair that your other friends have already settled down with partners of their own. When holidays come around the corner, when you finally catch a break from all the whining and fake wolf cries, you just have to hear your friends gush about how romantic their partners are to them. You secretly hate winter because of it. All those talks about Christmas gifts, their New Year’s couples resolutions, their stupid fancy ski trips that cost close to thousands of dollars, and then top it off for Valentine’s Day. Summer is more bearable, only because of the lack of romantic holidays, but you still get bitter from seeing their beach photos and international trips.

You change the position of your magic wand, facing it closer and pressing it harder down your clit, nearly drawing blood from your lips as you suppress back a frantic moan — a moan that’s a mix of both pleasure and frustration.

Fuck the students. Fuck your friends. And fuck this job.

“H-Haah—! Oh my god…” Your hips buckle feverishly, body quaking in your seat as you start to feel a familiar coil tightening in your stomach and a rush down below. A build up of tears start pooling at the corners of your eyes as your vision starts to grow hazy. Your heart heaves forward, about to burst out of your chest, the imaginary man just about to finish you off—

Creak.

Your eyes immediately pop open and the color drains from your face at the squealing sound from the door. You don’t have enough time to cover yourself up when you realize that a student is standing by the entrance, wearing an equally shocked expression on his face. A tousle of white shaggy hair, large gray eyes, appearing at a staggering height with—your gaze trail to his hands and nearly faint from the sight—his phone.

The sound of the door creaking again snaps you out of the phase and your arms fly over your chest, the words stuck in your throat and your vibrator falling to the floor.

Shit, what should you ask first? Has he been recording you this whole time? When did he even show up? You’re positive that you were the only one left in the academic building, so what is going on?

“Um,” The male has the audacity to walk in the room, his gaze fixated on everything but you. “Are office hours still open?”

What. The. Fuck.

You blink once, twice, and, when the student is still standing there, confirming your thoughts that he isn’t an awful mirage sent down by the Lord himself, you feel yourself internally shrinking.

“I-Is that the first thing you want to ask me?” You stifle back a laugh, or at least you think it’s a laugh. Maybe even a few waterworks for later. “Just who are you?”

But then it hits you. The black and blue duffle bag he has by his side had his name engraved on it. You don’t need to take a closer to recognize the national team’s logo and you certainly don’t need a Google search to realize that Nagi fucking Seishiro, a soccer prodigy and your apparent student for the semester, might’ve just recorded you masturbating in your office.

You manage to find an old jacket from one of the drawers at your desk and throw it on before pointing a harsh finger at the man. “Delete it, now.”

“Will I get an A?” Nagi is surprisingly blunt and, now looking back, this might honestly be the first time you’ve ever talked to him out of the whole semester. He seems to catch your perplexed look, shooting you a pair of creased brows back as he explains, “All of my other courses were remote because of training and football games… You were the only professor that denied it.”

You huff, seemingly annoyed that he thinks he can be an exception to your course rules. “I don’t hand out favoritism to just anyone and,” You glare at the phone in his hand, sneering right back at his uncaring facial expression. “I’m definitely not going to pass you if you’re threatening to black mail me.”

“Maybe we can help each other out?” Nagi offers, maybe a bit too fast and too eager.

You cautiously sink back in your seat, eyes narrowing at his suggestion. “What are you implying, Nagi?” The male shuffles awkwardly in place and your gaze flicks down, eyes widening for the nth time today and an audible gasp slips out. “You can’t be serious.”

“I need to pass and you—” Nagi clears his throat and motions to your slick covered vibrator, which is still very much on and buzzing away on the wooden floor boards near his feet. “You didn’t finish.” He rakes his fingers through his hair and adjusts the semi-hard length through his sweats with his other before finishing his offer. “I’ll delete the video, help you, and you’ll give me an A?” Nagi lamely suggests.

You want to scream, dig yourself a ditch large enough to fit you and the rest of however much pride you had left, and wither away. You’ve had students coming to you with plenty of other excuses, much more tamed than whatever situation you’ve found yourself in. And, regardless how much shitty this actually is, it doesn’t get rid of the fact that: one — you’re still sexually frustrated from having your orgasm ruined by this oversized, lazy fucker, two — you literally just got this job a year ago and getting fired for masturbating on campus might not look so great on your record, and three — if Nagi is true to his words, maybe you both can just forget about it the next day.

“You don’t get the control, I do.” You rise from your seat, allowing the jacket to fall from your frame. Your gaze hardens on the male subject in front of you as you bend down to reach for your toy, turning it off and putting it away in a nearby drawer that’s most likely filled with other student’s graded assignments.

Whatever, they’ll probably cry more fluids on it when they get their results back anyway.

Nagi tenses when you reach over to touch his arms, feeling up his toned biceps and rest of his upper body underneath the black hoodie, and he doesn’t dare to move unless you tell him to. You let out a scoff, feeling satisfied that he’s already willing to compromise so quickly under short notice. With a light tug on his sleeve, you drag him closer to your desk and settle yourself on top of it. You hike up your pencil skirt to your upper thighs and spread your legs wide enough for the width of his shoulders.

“On your knees, brat.”

He silently obliges, bending down on one knee and his hands find home on your inner thighs. You resist the urge to squirm under his touch, still feeling rather sensitive from your earlier chase and not wanting to give him any ounce of satisfaction. Without any audible exchanges, he allows you to direct his head closer to the heat of your sex, the combination of your increasing wetness and the hot puffs from his breath makes your stomach twist in anticipation.

With a quick swipe, his fingers brush aside your panties to the crease of your thighs and lean in, giving a few experimental licks to your slicked cover folds before burying the rest of his face in. Your reaction is instant. Your fingers claw their way deep into his shoulder blades, thighs threatening to squeeze the living life out of him, but Nagi’s grip is even more threatening. He stays rigid, palms glued to your thighs and keeping them in place as his tongue flicks against the stiff nub — drawing lazy circles.

Your mouth betrays your character as he suddenly decides to insert two digits, scissoring their way into your velvety walls. Nagi grunts in response at just how lewd you sound right now.

“Soaking wet…” He observes with careful eyes at your sex before looking up, a playful smirk flashes across his face when he notices the flush in your cheeks. With another twirl from his fingers, combined with the slow swirls from his tongue, your head rolls back as the torrent seems to be relentless.

With the next extra pumps, you cum hard with a shudder, vicing your thighs against his head. You can feel the leak of fluids slide out of your folds, and Nagi pushes his face inward, making sure he slid his tongue against that sweet spot of yours again. It blinds you with a final surge of pleasure, and you cry out as your orgasm shakes you to the core, nails biting into his shoulders.

You’ve never experienced an orgasm that intense before, even with the usage of your vibrator — hell, you can’t even remember when’s the last time a man has made you reach that high. Bright colors cloud your vision as you tumble through what seems like an endless bliss. Your body goes slack, back now flushed against the office desk, but Nagi’s body is still tense, his muscles twitching as he gets to his feet and lifts your legs off his shoulders.

“Hey,” Nagi slurs, wiping away your slick with the back of his hand. “We’re not done here.”

“W-What are you talking about—ah!”

Your vision is just beginning to clear up when you find yourself trapped between Nagi’s arms. He’s hovering above you, a certain dark look casts over his gray hues as he bores into your own. You swallow hard, heart beating faster when you look down to see his sweats already laid around his thighs and his cock springs free, head spilling with heavy amounts of pre. Nagi’s length twitches at the sounds of your moans and the male takes that as a sign of approval.

“What?” He leans forward, his bangs brushing against your forehead. “You’ve never seen a penis before?”

“Don’t get smart with me, brat.” You spit back, immediately tearing your gaze away from his rather impressive size. Might be the biggest you’ve ever seen in person outside from those awful porn videos online.

If you can find the energy to, you might’ve laughed at his lame attempt to have the upper hand, but Nagi doesn’t waste his time. He closes the distance, smashing his lips against yours, tongue already dragging its way down your throat. You choke back but recover quickly, hands flying to his locks, grabbing fistfuls, and rocking your hips against his hardened appendage. A sinful groan slips from his lips and lifts one of your thighs up, your ankle resting on his shoulder while he wraps the other around his waist.

You part your lips when he breaks away from the kiss, a thin trail of saliva connecting you two, and a whine spills from you as Nagi begins sliding his cock in between your folds. He sucks in his teeth, breath hitching sharply at the sight.

“Wanna put it in so bad—” He shudders seeing your slick engulfing his length. “Can I—Can I please put it in?” His monotone voice now replaced with a shaky resolve, almost as if he’s seeking for your next stage of approval and pleasure.

You reach up and cup his cheeks in your hands, eyes softening at his glassy ones. “Promise to delete that video and you might get a chance, Nagi.”

“Sei,” The male breathes out.

You tilt your head. “Huh?”

Nagi leans into your touch, nuzzling his cheeks into your palms. “Want you to call me Sei… Can you do that?”

“Sei…” You whisper out, suppressing back a laugh when you see the towering male tensing at the sound of his name. The twitching from his cock brushes against your clit making you squirm. “Sei, make me cum around that cock of yours.”

A cry escapes from the both of you when he slides in, inching bit by bit and holding your waist with both hands as leverage. You can’t do anything but throw your head back, sounds leaving your hoarse throat at the sheer size from him. Your hands can only reach his thighs, nails leaving their crescent marks on his skin as Nagi bottoms out inside of you with a long, agonizing stroke. Nagi takes his time, building a slow but steady rhythm, staring down at you with intense gray eyes and making sure the thickness of his cock stretches your walls as he continues. You suddenly feel grateful that you came earlier, the extra slick and foreplay made the insertion easier because you’re certain without it there’s no guarantee that you would’ve been able to handle this mind numbing fucking.

After a few more experimental strokes, Nagi finds a comfortable pace. You’re now starting to get used to him and it feels so, so good that you’re finding everything in your power to spread your legs as far open as they would go. Sensing your struggle, Nagi lifts one hand to push your thigh back even further, and you let out a yelp, whining when you feel him brushing against that sweet spot inside of you again.

A warm rushing sensation starts building in your stomach again and you feel as if you’re about to jump off a cliff. Your walls clamp down around his cock, wails starting to bounce off the walls and legs shaking without any means of control. You’re absolutely floored by the way Nagi’s able to make your body react this much under his touch. It’s only your first time having sex, yet it feels like he’d been making love with you for a lifetime.

Your eyes fly shut as the feeling of his callous thumbs make their way onto your swollen clit, rubbing and tapping away. Flames are riding your nerves, you can’t hold back any sort of resistance in your voice as he picks up the pace, hips slamming into yours and sounds of sex filling the air. Nagi moves swiftly and punishingly, holding your hips still and not allowing you any room to move around as his cock tears against that spot that had tears finally spilling down your flushed face.

“Sei,” You choke out a sob, throwing a hand over your mouth to try and suppress some of the noise. Though, you and him both know it’s a futile effort.

The build up of pleasure is so binding that you’re beginning to lose sense of time and place, feeling only the desperate and feral thrusts from your student. Your second orgasm fades slowly, leaving you in a pool of ecstasy, but that doesn’t stop Nagi.

Still hard and pumping, his grip on your hips only tighten and he grunts out a lustful moan. “Feels good, right? Cumming all over me?”

You look up to him, tears of pleasure disorienting your vision, and in a state where you’re too incoherent to speak — pleading only with your doe eyes.

Nagi understood immediately. He slows down his pace, leaning forward, making sure the head of his cock kisses the inside of your cervix before bending down to place one on your own gaping lips.

“Such a good boy, aren’t you?” You manage out.

He groans at the pet name and peppers your face and neck with wet kisses, lifting your leg with one hand so that he can slowly stroke back and forth inside.

One of your hands reaches for your chest, fondling and toying with your nipples while your other hand reaches for the back of his head, gripping his white locks and pulling him down for another feverish kiss. Your lips remain sealed and pressed together in a battle of tongues as he rocks inside of you, sending you yet another orgasm as he moans into your mouth.

“H-Haah—I’m close…” His hips buck wildly. “Gonna cum inside of this pretty pussy…”

Nagi finally comes undone inside of you, his whole body shuddering as coats of white paint the insides of your velvety walls. A heavy pant from him catches your ears as he pulls out slowly, eyes admiring the hot, white trail that travels down your thighs and onto your desk.

By now, you can barely keep your eyes open, both mind and body exhausted. You try to get up, only to find zero strength left in your limbs, but soon you feel a pair of toned biceps around your waist and Nagi pulls you into his firm, yet comforting chest.

You want to ask him something again, something regarding that video he took of you earlier, but you’re beginning to lose your train of thought as exhaustion creeps up. Your entire body aches and your pussy is still emptying his remaining orgasm. But, strangely enough, you find yourself not caring about it anymore.

A smile makes its way onto your features as you drift off to sleep, making you miss the fact that Nagi did delete the video shortly after and scribble a quick note next to your purse. It’ll be another hour before you have the chance to read it.

‘Don’t forget that A. XXX-XXX-0506 - Sei.’
