Yukimiya isn't sure when, but eventually, tutoring you took up a huge portion of his life. First assigned for a homework task that you had not completedâhis teacher made him tutor you on how to do it and exactly how to hand it in.
Then, his math teacher made him study with you, since you were falling so far behind. You and him spent hours studying together, but nothing ever worked. Either you got him too riled up to continue this session (which really, led into a session of something else), or you yourself were way too unfocused to even consider actually trying to learn from the boy in front of you.
Either way, you and he did not mesh well together, especially in a study-like area. In a libraryâyou were far too loud. At home (either one of your houses)âhe was practically asking you to feel him up, God forbid you two were left alone in the house, as well. Even at school, you kept finding yourself getting distracted by the multitude of people that pass by, and every little thing around you intrigued you more than your work ever did.
You never read your assigned novels, something which he couldn't understand. It was just reading, and yet, you acted like it was the hardest thing in the world to do? Whatever the reason was (perhaps you could simply not read), Yukimiya needed to find a strategy that worked for you.
As your (self-proclaimed) tutor, was it not his job to make it so you don't flunk every single test? He thought so.
So, he went through various strategies with you. Studying in timeslotsâit didn't work, because when you took a break, you decided that you didn't feel like going back to doing boring old work. Cramming everything in at the last minuteâthis worked a little better, but was still a giant failure. Sure, it had you actually studying, but you forgot everything as soon as you walked into the test room since your mind had no time to actually process it all.
Whatever it wasâit was like your entire being refused to study like it would kill you (from how badly your grades are dropping, he isn't sure that's the only thing that will). A vivid procrastinator, that's what you are. Still, Yukimiya Kenyu is nothing but determined. When he's set on something âyou best believe he'll go out there and get it like a champ.
That's why he was sure that this study methodâtailor made to fit youâwould absolutely, undoubtedly work.
You were surprised when Yukimiya asked you if you wished to spend this week's weekend study session at his house. (He isn't dumb, in fact, he's the complete oppositeâand he knows exactly where you two "studying" at a private place like home leads).
So why did Yukimiya ask this? Has he perhaps turned over to the dark side? The thought of thatâand perhaps, at what's to comeâmakes your stomach twist in excitement.
The day came without so much of a hitch. You spent the last few days of the week lazing as usualâyour mind couldn't leave the thought of this weekend's "study" sesh with your favourite boy alone.
You wondered this, even as you took a train and made your way to his houseâyou've been there so often that his address was practically branded into your brainâand you thought about all the things he'd make you do.
Your face flushes.
As soon as you ring the doorbellâyou stand outside waiting for less than a minuteâyou catch sight of Yukimiya Kenyu himself. Clad in a flowy, white dress shirt, and baggy grey sweatpantsâhe looked deliciously domestic, and it made your heart race in your chest. Especially when he spares you that smileâthat godawful, lady-killer smile that could knock somebody deadâyou think you may faint on the spot.
"You're just on time. My parents are going out to see my grandma, so it'll just be me and you alone for a few hours. Should be more than enough time for substantial studying, no?"
Alone? Few hours? Come on, Yukki, you know me better than that.
Now, you were starting to grow suspicious at his deliberate choice of wording and his all-too-well grin. Yukimiya Kenyu... what are you planning? Are you actually planning on getting any work done? No, not really. But that doesn't mean you can't be suspicious of this pretty boy in front of you. A studious, straight-A nerd would surely not fall into his tempting desires without at least a little bit of proddingâwhich is exactly why you're so wary of this whole setup.
You're led to the familiar sight of his room, somewhere you've been countless times before, same as always. You make yourself comfortable on his bed and watch as he pulls in a second chair to sit at his desk. He sits down at the one he just brought in, and motions for you to take a seat beside him on the chair he had originally had on his room.
His smile is so guileless, you can hardly get a good read on what he's feeling. It almost makes you nervous. Still, you obey, and take a seat, watching silently as he pulls out a few binders and unclipped a piece of paper. A mock test.
Wow, already? He was making you go through a practice test based on the subjects you're learning in math at the moment. Well, this wasn't too surprising. Yukimiya usually went through these with you anyway, so he could get a feel for how much you know about the subject already.
He snuffles his chair closer, eyes gleaming behind lens, "We should spend today going over these questions. If that doesn't take much time, we can just spend the rest of the day chilling out."
Yeah, we all know what you mean by "chilling out".
You nod, back slumped into the chair behind you and you groan, "Ugh... that sounds boring at hell... Can't we do something more fun, Yukki?"
With a cheeky grin and a knowing glance at the bed behind youâyou think you make your intentions abundantly clear. You're certain he knows what you meanâthis is always how you get what you want, after all.
By now, he'd be pink-cheeked, or perhaps even sloppily making out with you already, but not this time. He keeps the same blank, air-headed expression that he's plastered on his face since this whole tutoring thing started. "No, not this time. I've thought of a way to help you remember the fornulas, actually. I'm sure this strategy will work."
You raise a brow, clearly suspicious of his judgement. He said that same thing the past three times, and you ended up failing said three tests. "Really?"
He nods, smiling, "Really. Let's just start, and I'll try to incorporate it as naturally as possible."
Strange choice of wordsâbut you like to trust your Yukki, so you don't question it. You and him quickly flip to the first page, and it starts with a question on area for a shape you do not recogniseâwith all sorts of numerals and numbers that it already makes your head spin.
"Do you understand how to solve for x?" He asks, and you think it's easier to straight up say no, rather than lie and look stupid, so you shake your head. "Alright. I'll try to explain it the best I can."
He starts talking, but it's hard to focus when his big hand is taut on your bare thigh, rubbing up and down mindlessly on the skin. You didn't realise he'd come so close to youâhe's practically pressed up against your side.
Whatever. You try not to think too much of it. You focus on the sound of his words and sort of figure out how to solve what they're asking, "So, to find x, first you have to use the measurements already given, and then times that?"
He nods, "Yes, but that's not the end. You then still have to find y and z."
You groan, running a hand through your hair and sighing loudlyâshowing off your exhaustion five minutes into the session, "Ugh... this is taking forever... is this shit seriously on the test?"
Yukki leans up and presses a peck to your forehead. It feels oddly romantic, it makes you blush, "I know it's long, but you'll get it. Just focus, alright? I promise you'll understand if you do."
You really hope his mystery study method actually works.
Yukki continues trying to explain the concepts and formulas on how to solve the shape on the paperâand you're trying, you really are, but his fingers inch up, further and further and it makes it really damn hard to concentrate.
(Curse him, and the stupid effect he has on you.)
His hand stops moving for a moment, and you finally feel like you can breathe again. His words finally stop sounding like a jumbled mess and more like actual teaching, "I get it! You just..."
You proceed to re-explain the concepts he brought up, and worked out the question on the paper with ease. Yukimiya grins, perfect pearly whites behind his teeth and he's clearly proud, "Good girl. You're actually listening to me this time. Let's move on to the next question."
An algebraic expressionâso many letters, numbers and symbols and you don't know what half of them mean. Yukki takes one good look at your face and understands exactly what's going through your headâabsolutely nothing.
He begins to explain the equation to you once moreâhis hand inches up even further. It has practically disappeared under your skirt.
Is he doing this on purpose? You can't help but wonder, heat crawling up your neck and your stomach feels tense with anticipation. Usually, you'd think he would beâbut he's not even looking at you, completely and utterly focused on the question.
Maybe he doesn't even realise.
The thought makes your skin crawl, but you push down these feelings (and try to ignore the soft touch of his fingers on your inner thighs), attempting at solving the question.
He shakes his head, brown curls falling over his pretty eyes. "No, that's not how you do it. I'll show you."
He leans forward and takes the pen from your handâfingers brushing over yoursâand wastes on time in solving the question while explaining its properties and what steps you need to take. Yukki is a good teacher. He's smart, he's thorough, and he makes sure you understand everything before you two move on.
But you really, really, can't focus because his fingers are now right atop your clothed cunt, stroking softlyâit's driving you madâand languidly, like it didn't do anything to you.
You hiss through your teeth when his index finger brushes over your clit, "Yukki..."
He looks so genuinely confused you almost believe he does not realise what he's doing, "Hm? What? Do you not understand?"
You furrow your brows in an angry motion, "No, are you kidding? You... You'reâ" The words die in your mouth as soon as you catch sight of the glowing, very much teasing, smirk on his lips.
Fuck. He does know what he's doing. Fucking prick.
You swallow thickly when his fingertips press a little harder, "Is this seriously the strategy you were talking about?"
He still acts oblivious, despite the way he's unabashedly glowing with joy, "I have no idea what you're talking about. Let's just get back to the question. Do you understand it?"
You suck up your pride and take the pen from his graspâsolving the question easily. Yukimiya places his free hand on your head and pats it as a rewardâhis fingers stop moving so you have time to recuperate your thoughtsâbut this process soon repeats itself through the next three questions.
You can hardly think straightâbut, a thought passes over your mind that maybe if you finish this up as soon as possibleâhe will finally stop teasing.
You find yourself working as quickly as possibleâthe sight is enough to please him. Perhaps this strategy really was working. Yukimiya thinks he's struck gold.
You look just like a regular diligent studentâwell, as diligent as a student can get with a hand shiver with their skirt. You're solving these questions with minimal difficulty and you're actually showing your working out. He hasn't felt this proud since he brought his pet turtle to show and tell in seventh grade (you teased him relentlessly for weeks after that, but he took like like a champ out of love for his pet).
... But still.
Perhaps a part of Yukimiya is rather selfish. A little voice that would never speak unless he found himself caught in a situation like this with you speaks up inside his brainâwhich makes his eyes glaze over with a sultry gleam and a small, almost harmless thought appear in his head.
What if...
With his sudden movement, you jolt in your chair and hands fly to his wrists, clutching it over the fabric of your skirt. "Y... Yukkiâ!!! WâWhatâ"
His two middle fingers plunge deep into your cunt and immediately take up a relentless paceâyour chest begins to heave as he consistently keeps pressing against that soft, squishy spot inside of you that makes your mind fog up.
There's no freaking way you can act likeâ The thought dies in your throat when the heel of his palm rubs against your clit and you bite back a small whine.
The small little clicking sound that is made each time he thrusts his fingers in and out is almost inaudible in your ears when he begins to speak, lips brushing against your ear, "Keep going, gorgeous. Don't let me stop you now. You're doing so good."
Your leg jitters against him when he smiles against your ear and he feels your cunt pulse.
Still, you pick up your shaky fingers and try to keep a steady grip of the penâit's hard when all you want is to throw your head back on his shoulder and sit there all pretty for himâbut you know better than to ignore Yukimiya Kenyu.
Despite his gleeful demeanor, he seems to take joy in asserting himself over you. You wondered if maybe he just had a sick kink.
Every time you came close to solving the questionâhe would press harder and harder, and every time you tried to lean back onto his shoulder, he would stop abruptly and ask you what you think you are doing.
You just could not win with Yukimiya Kenyu.
He's driving you crazy. Maybe this is how you make him feel on a daily basisâbut you actually think you're going to go mental from this torture. Your handwriting had gotten noticeably messier and more shaky every time you tried to solve that questionâeven when you did, his pace was absolutely relentless. He did not let up.
"Yukki!" You whine out, cheeks all puffed like a cute little fish and you glare at him with so much anger he actually almost feels bad for a second. Almost.
He takes far too much enjoyment in something like this to feel any menial sense of guilt toward you. Besides, it's not like you didn't have this coming. Despite all this, he knows you will take whatever gives you graciously because you are absolutely enamored with him.
(He thinks that, with a small smile. It's okay for him to say that, right? It's not like it's not reciprocated.)
"Yes?" He responds, slowly, teasingly. He can feel your thigh start to shake as a sign of your impending orgasm, so he starts to slow his thrustsâthe tantalizingly sluggish drag of his fingertips across your walls give you a little more than nothing.
You could scream in frustration. He grabs ahold of your thigh and tugs it over his left leg, so that you don't get a chance to close your thighs are his handâit makes it all the more torturous.
Your words are breathy and heavy on your tongue, "Yukki... lemme... please let meâ"
His thrusts speed up, and his thumb begins to rub hard circles on your clit. Your chest heaves with each breath and you start to moan sweetly into his ear. You throw your head back, onto his shoulder and grip onto your skirtâbut this time he does not stop. In fact, he seems to go even faster.
You can practically envision the smug expression he must have on his face at this momentâhis ego fed and arrogance through the roof. "What? You wanna cum?"
Mindlessly, and desperately, you nod. White-hot fire starts to churn in your lower belly and it spreads to the tips of your toes when he keeps rubbing harder. You're getting close, with your stomach twisting and heart beginning to beat in your ears.
"YâYeah... please..." Somehow, you manage right choke that out and whimper right into his ear.
Your thighs begin to shake. He does not stop. "You wanna feel good, gorgeous? Go ahead." He presses a soft, chaste kiss to your templeâan almost laughable contrast to how you're nearly brought to tears by your orgasm, lower half shaking and rutting up into his unrelenting touch with a sense of desperation.
He likes it when you're desperate. It makes you all the more cute.
He helps you ride out your pleasure, all with a pretty grin. Your babbling thanks and praises for his fingers soon die down when your post-orgasmic haze hits you, and you lean back into his touch with low breaths.
After a few minutes of him just holding you like this, hand placed lightly on your thighâyou look up at him, then down, then back up again. "You want me to help you out with that?"
He seems to be slightly taken aback by your bold offerâdespite moments before, he sported a cocky smirk and sultry gazeâbut manages to gather his composure quickly enough to answer.
He shakes his head and gazes at you kindly, "Oh, you don't have to. I still need to teach you some more formulasâ"
Your brows furrow and your remove your leg from over his. "Yukkiâdon't be like that. Lemme take care of you, okay? Yeah..."
A smile falls upon your lips as his cheeks grow pink. Even when your duck down below his deskâit feels all so surreal. Even when you tug down his grey sweats that did not hide anything, it almost feels like a figment of his imagination.
It no longer does when he feels the fiery enclosure that is your lips wrap around the redden leaky tip of his cock. Yukimiya slaps a hand over his mouth and squeezes his eyes taut shut. His heart is beating a million miles an hour in his chest. He feels like he cannot breathe, but the air gets knocked out his lungs all the same when your move your mouth down.
You use your hand to spread his pre around the base of himâjerking off what your mouth did not fit, until you go a little lower. He thinks his face may be on fire. The hand that does not cover the lower half of his face grips the edge of his table with full force.
He dares not to look down at you and dares not to catch the nasty, foxish gleam in your eyes.
You go down more, then back up. You press a chaste, loving kiss to the bulging tip, then, you go back down again. This time, a little further. You keep doing this until your jaw relaxes enough for your nose to press against the smooth skin of his abdomenâyou allow your hands to wander his hard stomach.
"[name]..." His voice trails off shakily, a small moan escaping his lips as his hips jerk forward. You choke a little, but keep going. His glasses are growing foggy from his hot, heavy breaths and he doesn't think he's ever felt any hotter.
The room temperature must have shot up by at least twenty degrees. He feels searing.
Yukimiya's heart nearly beats out of his chest when you pull back once more, staring directly into his half-lidded, cloudy amber irises, and gave a sloppy kiss to the cute little freckle that was on the pulsing head of his dick.
His breathing picks up and his chest heaves. Fuck.
He groans aloud as your mouth sinks back down and your throat presses around his cock. His hips jerk forward again, and he takes this reaction as his opportunity to start thrusting. You suddenly sit still with your jaw as open as it would allow you to beâas Yukimiya lazily thrusts into your mouth.
His hand entangled itself into your hair and he grabs a tight hold of your head as he moves you to his heart's content. The wet choking noises that you make when your lips are snugly wrapped around the base of his cock give him butterflies.
He looks down at you, sweat beading on the side of his face and low grunts escaping his lips, "Ffffuck.... So... mmmm..."
He can hardly firm actual wordsâhis head lolls back and his eyes shut in pure bliss.
Searing hot electricity zaps through his veinsâhis abdomen contracts, and it's a telltale sign he's getting closer. You use your tongue as much as possible while his thrusts are getting wild and erratic âhis groans soon turn into desperate puffs of air.
"[name]...! Gonna..." His hot and heavy pants ring in your ears and his low groans are such a noise you'd never expect to come out of such a perfect pretty boy's mouth. He pants hard. "[name]...!! [name]...!!"
It seems your name is the only word he can formulate at the moment, when his cock twitches in your mouth and spurts of white shoot out the tip right into your throat.
He grabs your hair hard and presses you as close to his abdomen as you can getâhips shaky as you squeal and your throat instinctively tightensâthe whine he lets out is something that will forever be imprinted into your memory.
You nearly cough it all up when he finally pulls out of your lipsâbreathing growing steady and shoulders relaxed into a calm postureâbut you force yourself to swallow, and you give him the cutest smile you can possibly muster when you do.
Yukimiya stares down at you with hazy honeyed eyes filled with unbridled lustâhidden only behind the fogged up lens of his rounded glasses. "[name]... You..."
He looks embarrassed when you stick out your tongue at him and it is perfectly clean. He places a big hand on your headâa stark difference compared to his previous way of gripping your hairâhe strokes it softly under his touch. "Good girl..."
He chuckles.
Yukimiya Kenyu looks absolutely debauchedâyou don't think you've ever seena prettier sight. His shirt is disheveled and his cheeks are a searing hot red. He is absolutely gorgeous.
That why, when you crawl up from your kneeling position, and he cradles your aching red knees when you place yourself flat on his lap, you kiss him with all the love you can muster. You do not feel much loveâbut all of the adoration you do feel is directed solely at Yukimiya.
"So, how did I do, Mister Tutor?" A teasing, coy smile places itself on your lips when you pull away, hand sneakily running itself all over his hard torso.
The smile he beams at you is nothing less than radiant. "A+."
