CHAPTER 1 CHAPTER 2

kohai: junior

Since you were coherent enough to walk home without help, Denji insisted you play that fighting game with him almost immediately upon entering the apartment, not hesitating in the slightest when he resorted to guilt-tripping you about being gone last night when it looked like you might say no.

Surprisingly, Aki sat at the table, watching the two of you as he nursed an Asahi from the fridge. He was mostly quiet, save for a few underhanded comments to Denji when his character was getting its ass kicked. You played for maybe an hour before Denji was actively passing out with the controller in his hand.

Aki stopped you when you moved to roll Denji’s futon out. I got it, you should rest. Like you were some sort of invalid and not just a drunken degenerate. Any retort you had stocked in your mental arsenal was lost on your tongue when his gaze fell to that side of your neck, a barely noticeable dusting of pink littering his cheeks. Instead of whatever stupid thing you had in mind to say, you blurted out a too-fast “Goodnight!” and ran off to your bedroom.

You’re not sure how long it’s been, but you haven’t slept. Staring at your ceiling, replaying over and over the way Aki’s hands had felt on you, the eagerness of his mouth on your sensitive skin. The electricity that shot through you from his touch was a separate beast entirely compared to how it had felt when it was Daichi, and you wonder what might’ve happened if you hadn’t been interrupted, or if he had decided to take you back to the apartment instead of returning to the group.

You hadn’t thought in a million years he would ever go for it like that, and you’re still having to convince yourself it even happened at all in an attempt not to gaslight yourself. He’s been acting no differently than usual since it happened, you’re not sure if you should be relieved or disappointed.

You might be a little disappointed.

“God damn it,” you whine quietly to yourself, covering your face with the crook of your elbow.

Aki’s embrace alone had been enough to make you uncomfortably soaked, and if you’re being honest with yourself, it never really stopped. Even now as you’re laying in bed, in your favorite giant t-shirt and fresh underwear, you can feel arousal seeping out of you, enough to where you’ll likely have to change your panties again.

Letting out a tired sigh, you give in, cursing Aki’s name under your breath as you slip your hand under the elastic of your underwear. You aren’t going to get any sleep if you don’t get this out of your system.

***

Aki hasn’t been keeping track of the number of cigarettes he’s had today, probably too many, but fuck, he wants another one.

He’s turned on out of his mind, but he can’t even bring himself to rub one out because of how guilty he feels. Taking advantage of you in the izakaya restroom wasn’t exactly what he had in mind when he wanted an excuse to take care of you, and he’s terrified that you’ll hate him tomorrow when all the alcohol is out of your system and everything’s back to reality.

He just couldn’t help himself, the way you were looking at him so innocently, completely ignorant to how many times he’s imagined what it might be like to feel your bare skin under his fingertips and have the taste of you on his tongue.

Aki couldn’t even look at you when you went back to the table, afraid it might be obvious something went down between the two of you to the rest of the Division. While Himeno had teased him initially about taking an “awfully long time”, she dropped it fairly quickly when he refused to take the bait. He could feel the way Denji kept eyeing him from the other end of the table, of course, the hybrid being the only person there sober enough to sense something was weird.

As dense as Denji is, he’s still probably a little more perceptive than someone who has at least five cheap beers in their system. Likely for your sake, though, he kept his mouth shut. The accusatory glares he was throwing Aki’s way said a lot on their own, and he had even demanded to be the one to help you out of the building when it was time to leave, grabbing your bag for you and everything, which made Aki wish he had shattered his nose this morning instead of just causing some light bleeding.

Breathing out a sigh, he sits up in his bed. He hasn’t even changed out of his uniform yet - with the exception of loosening his tie - too scattered to do anything but brood.

If there was a devil on his shoulder, it would be telling him how much of a dumbass he was for not insisting on taking you home as soon as you left the bathroom, that he might not ever get a chance like that again. He has no idea what the fuck an angel would say, good job not sticking your dick in your inebriated kohai even though you really wanted to?

Repressing a shudder, he shakes his head.

He did really want to. He still does, the way his cock is stiff in his pants and the high likelihood of precum staining his boxers is proof of that.

Glancing at his closed bedroom door, he wonders if you might still be awake.

Actually, he’s not sure he cares if you are, sleep deprivation and the ghost feeling of your warm body in his grasp bringing his Mammonistic longing to a fever-pitch. If you are asleep, he’ll wake you up, even if it’s just to apologize. The idea of you withdrawing from him or resenting him makes his stomach lurch, he doesn’t think he could bear it. He needs another chance to touch you again.

I’ll just see if her light is still on, he tells himself as he stands up, carefully creeping out into the hallway, almost silently.

I’ll leave her alone if it’s dark, he promises as he stands in front of your door, his Adams apple bobbing in his throat. Maybe she won’t even remember what happened.

Fuck.

His heart sinks like a stone in his chest when there’s no light filtering out the bottom of your door, his hands flexing impatiently at his sides. As much as he wants to reach out and turn the handle, he can’t bring himself to.

About to throw in the towel and skulk back to his room, he suddenly freezes, hearing something. Holding his breath, he presses his ear against your door, wincing at the clicking sound of his earring against the wood.

He hears something again, hushed swearing followed by the dull thud of hurried footsteps.

What the hell?

He’s not quick enough to get out of the way when your door suddenly swings open and you barrel into his chest, your nose slamming into his sternum, making him wheeze.

“Fucking ow…” You cover your nose with your hand, not seeming to register what happened until you’re looking up at him, a crease forming between your brows. “What- why are you standing outside my door like some sort of ghoul?” Your voice is a confused whisper, muffled by your palm.

Aki’s face burns as he looks down his nose at you, his hands lightly holding onto your upper-arms. “I was- um, I’m sorry…” He wets his lips nervously before adding in a low tone. “Why were you charging out here like you were about to kick somebody’s ass?”

Your eyes widen, and Aki can see pink blooming behind your fingers. “I wasn’t!”

“You sure? Cause I’m pretty sure I’m gonna have a tiny, nose-shaped bruise on my chest tomorrow.” He grabs at your wrist, trying to pull your hand away from your face. “Let me see.”

You resist for a second, but inevitably relent, allowing him to expose your bright red nose. He nearly smirks at the childish look on your face.

“Does it hurt?”

“No.”

You both kind of just look at each other for a moment, matching dark circles under your eyes. He regrets not stopping by the washroom beforehand, he’s sure he must look like a fucking nutcase the way his hair is loose and messed up from tossing and turning, and how he’s still in his Public Safety uniform even thought it’s likely past 3:00am. While your hair is also disheveled, he notices that you washed your makeup off, and changed into that way-too-big shirt you like.

So damn cute. It’s almost annoying. Additional frustration is piled on when he realizes he can’t tell if you have anything on underneath, shorts or otherwise. Chewing on the inside of his lip, his gaze travels above your head and into your room, which is dimly lit by the small lamp you have on your nightstand. You seem to notice where he’s looking, and you panic, barring your doorway with your arms like you’re a bouncer. “D-don’t look!”

He quirks a brow, amused that you think barricading the doorway with your body will somehow prevent him from seeing over your head.

The way your arms have lifted, the hem of your shirt slides up your thighs, and he can tell for sure now that you definitely don’t have your usual shorts on. He feels beads of sweat form on the back of his neck. What were you doing, storming out here in nothing but a t-shirt?

Ignoring your dramatic whisper-yell of protest, he looks anyway. Right away, he can see at least three different vibrators strewn about on your floor, recognizing them from his indiscretion earlier. His heart jumps in his chest, blatant surprise on his face when he looks at you again.

Lower lip trembling, you bury your face in your hands, like that would somehow make you disappear. “You- I said not to look…” Your voice is small and pathetic, Aki might feel sorry for you if it wasn’t for the pure elation he was experiencing.

You had been awake all this time, playing with yourself. Unsuccessfully, he determines, from the way it looks like your toys had been thrown and the way you seemed obviously frustrated. A divine smack of understanding hits him, and his eyebrows shoot up. Were you about to seek him out, and he just happened to beat you to it?

A loud snore comes from the living room down the hall, Aki makes a hair-trigger decision and gently pushes you backwards into your bedroom. You’re too humiliated to fight.

You still don’t uncover your face, even when you hear the door ‘click’ shut and he leads you to sit on the edge of your bed, the mattress dipping when he takes a spot next to you.

“Are you gonna come out of there?”

Wordlessly, you shake your head side-to-side.

Aki sighs, and you feel weight lifted from the mattress.

A shocked yelp leaves your lips when you’re roughly shoved backwards onto the mattress and your hands are torn away from your face. In a split second your wrists are bound in Aki’s hand and firmly planted above your head, leaving you nowhere to hide as he looms over you.

“It’s too late for this,” he mutters, his voice authoritative and tinged with exhaustion. “You were about to come to my room, weren’t you?” The grip on your wrists tightens, phthalo eyes scorching into you beneath hooded lids. “You must need something, huh? Tell me. Use your big girl words.”

He doesn’t let up, even though your eyes are huge, watering from shame and embarrassment, tears pooling at your lash line. He doesn’t care that you’re looking at him like a scared rabbit that’s just been ripped from the ground only to be rudely plummeted back into the earth, broken and split open so hungry mouths can feast. He’ll beg for forgiveness later. For now, he needs to hear you say it.

Finally, you speak, a pitiful waver in your voice.

“I just- I needed…” You look away, sniffling as a frustrated tear threatens to spill over and trickle down towards your ear.

Aki should feel guilty at the sight, but instead it makes his cock throb, and all he wants to do is lap it up. “What do you need?” He loosens his grip on your wrist, just barely enough so he can soothingly stroke at the skin with his thumb, murmuring softly. “I won’t know how to help you unless you tell me.”

His eyes fall to your breasts, pupils darkening when he notices the peaks of your nipples straining against the fabric of your shirt and the way you rub your thighs together, squirming under his scrutiny. Rudely, he forces your legs apart with his knee, making it so you’re unable to get any sort of friction, ignoring the petulant whine it earns him.

“Come on,” he coaxes, his free hand moving to rest on your thigh, digging his fingers lightly into the soft flesh.

“…more…”

The word makes Aki’s heart skip a beat. He could barely hear you, only certain you said something because of the intent way he’s been watching your mouth. “Louder.”

“More.”

The neediness in your voice betrays the dirty look you’re giving him, forcing him to suppress a smirk. He’s not going to ask you for clarification, there’s no need. He can sense the warmth radiating from the apex of your thighs through the material of his slacks, and he’s not even touching you.

“There you go. That wasn’t so hard, huh?” There’s a hint of mockery in Aki’s voice, but a tenderness in the way he searches your expression. Slowly, he releases your wrists, moving to cup your cheek in his palm. “Keep your hands away from your face,” he warns, thumb caressing the damp skin under your eye.

When you offer him a meek nod, he dips down to place a soft kiss onto the corner of your mouth. “I’m going to touch you now, okay?”

The question is rhetorical. When he slides his hand further up the smooth skin of your thigh, he can feel you shiver underneath him, and when his fingers meet the edge of your panties, you cling onto his biceps tight enough that he can feel your blunt nails through his blazer.

Slipping underneath the fabric, he’s met instantly with the wet heat of your pussy, groaning softly when the tips of his fingers are drenched in the sticky arousal leaking out of you.

“You are worked up, aren’t you?” He murmurs against your lips, slowly tracing up and down your slit, like he’s trying to memorize exactly how it feels. “No wonder you’re being such a crybaby.”

You let out an annoyed sound of objection at his teasing and he’s quick to placate you, molding his lips to yours, his tongue sliding eagerly into your mouth when you allow him access.

The hand that had been cupping your cheek creeps lower to lightly wrap around your neck, giving it a possessive squeeze before releasing it to cradle the base of your skull instead. Deepening the kiss, his tongue languidly explores your mouth while his middle finger begins to tease your entrance, eliciting a soft gasp from you. To his benefit, his knee prevents your thighs from clamping shut, and he smoothly slides his finger inside you. A strained sound gets stuck in your throat and your hands are quick to find the nape of his neck, your nails scraping against his scalp as you pull at his hair.

Aki lifts from your mouth enough so he can look at you, his eyes darkening at the blatant desperation on your face. “Look at you. All this over one finger?” His thumb swipes idly at your clit while the digit inside you glides in and out at such an unhurried pace it’s almost tortuous, you feel like you’re going to lose your fucking mind.

“Such a dick,” you mutter half-heartedly under your breath, letting out a hiss when he adds another finger, stretching you more.

Continuing his agonizingly slow ministrations, he grips your face with the hand that isn’t buried in you. “Me?” He asks sternly, gazed locked onto yours. “The guy who’s playing with your pussy?”

“Yeah…” Nearly a whisper, the nervousness in your tone makes the word sound more like a question than a definitive statement. The calculated way he’s looking at you is almost unnerving, and it makes you clench involuntarily around his fingers.

You almost let out a cry of disappointment when Aki abruptly slides his hand out from under your soaked underwear, body straightening so he’s no longer looming over you. Expression never wavering, he removes his tie, folding it up into a neat square while his eyes rake over your body. Inadvertently, you have just given him an opportunity to see how far he can push you, and he’s not going to waste it.

“What are you-”

“Open your mouth.”

“Wait- why?” You stammer, blinking up at him.

“Well, since you think I’m such a dick and all, I would regret it if I didn’t do my best to live up to your expectations.” He states calmly, a flicker of something unreadable in his gaze. “Open up.”

When you hesitate, a trickle of ice drips down his spine, worried he may be going too far, assuming too much. Even if you’re willing to let him touch you, you have no obligation to do what he says outside of work. You could very well tell him to fuck off if he pushes it and he’s honestly surprised he’s gotten this far already.

Feeling like he’s starting to suffocate from the weight of “what ifs”, he’s seconds away from groveling when you obey, propping yourself up on your elbows. There’s a hint of confusion in your expression, but the intrigue under the surface is stronger, and a balmy wave of relief washes over his body.

You barely part the seam of your lips when Aki grasps your jaw, stuffing the folded tie into your mouth, deep enough to where you’re probably uncomfortable but not enough to make you choke. He would be lying to himself if he said he wouldn’t love to see you gag, but he’d much rather it be on his dick. The tie is just a pacifier, to shut you up for a minute so he can do what he wants and give you what you need.

“That’s better,” he remarks, heart beating wildly in his chest. Your pink lips are stretched, mouth full, a surprised and sheepish look veiling your sweet face. His cock is practically pulsing at the sight of you.

Unceremoniously and without warning, he flips you onto your stomach, ignoring the muffled noise of protest as he lifts your hips into the air so your back is beautifully curved and arched for him. A smug smirk plays at his lips when you glare at him indignantly over your shoulder, maintaining eye contact as he shrugs out of his blazer, tossing it to the floor before popping open the first two buttons of his shirt.

“It might be uncomfortable, but I need you to put your hands behind your back.” He says plainly, undoing his belt and sliding it out of the loops of his slacks, the swishing sound making you flinch.

At this angle Aki can see the wet spot on the crotch of your panties is almost completely soaked through, making his mouth water. You’re quicker to comply this time, a lingering mixture of hesitance and anticipation in your gaze. As soon as your arms are behind your back, he wastes no time securing your wrists together with the thin leather material of his belt, careful not to cut the circulation off to your hands, muttering soothing words of praise at your cooperation.

Leaning back to appreciate his work, he’s sure it must be painful.

The way your chest and the side of your face is crushed into your bedding, unable to support your upper body in the slightest, an almost unbearable amount of strain put on your neck and shoulders from having your arms forced behind you. Aki can hear a quiet, pathetic sound coming from your throat, but you make no move to adjust your position, eyes glimmering when he gently murmurs. That’s right, stay just like that for me. Such a good girl, aren’t you? Always out to please, even if it hurts.

Your shirt is pooled near the base of your ribcage, exposing the skin of your back, the soft curve of your waist and hips. Greedily, his hands roam over you, gripping possessively at every give of flesh, every dip and contour you have to offer him. His touch seems omnipresent, scorching you from the inside out. Even though he’s been neglecting the part where you need him most, you’re practically writhing underneath him.

“Getting impatient?” Aki asks in a patronizing tone. His hands find the meat of your ass, fingertips digging in aggressively before moving upward to tease at the waistband of your underwear. You look up at him pleadingly with lacquered eyes. He huffs. “Since when did you get so spoiled?”

In a careful yet deliberate motion, he slides your panties down over the swell of your backside, leaving them limp, drenched and useless around your knees.

Aki sees you clearly now. Dripping wet, bare and glistening, completely vulnerable. He’s almost too dazed to note the little sound you made at having your needy sex abruptly exposed to the cool air of your bedroom.

Fuck. Gritting his teeth, his hand flies to pinch at the tip of his cock over his slacks. He’s been painfully hard for a while now, and seeing you like this nearly sent him over the edge. Taking a couple breaths, he tries to pull himself together.

“It’s like you think you’re the only one who’s been suffering,” he mutters, voice strained and barely audible as he spreads you, watching a trail of arousal drip down between the V of his fingers and onto the back of his hand. “Is that it?” He’s so close now that you can feel his breath ghosting over your sensitive flesh, making you shudder.

When he places a tentative kiss onto your already swollen clit, you let out a muffled cry, flinching involuntarily at the sensation.

“Hold still,” he warns, hands moving just below your ass to grab onto the sides of your thighs, preventing you from wriggling around. Flattening his tongue, he runs a hot stripe from your clit up to your opening, forcing his tongue inside and swallowing the juices that trickle down his throat with a low groan.

You can’t think anymore, not even of the burning of your shoulders or the way it’s hard to breath with your chest crushed against your mattress. All you can think of is the way Aki’s tongue feels on you, desperate and sloppy at one moment, precise and leisurely at the next, his grip on your thighs almost bruising.

The tie in your mouth is drenched and drool has started to spill out the corner of your mouth, soaking into the bedspread beneath you, but you hardly notice. Aki’s fingers are in you now, pumping slowly in and out while he lazily sucks at your clit, you can feel a hot coil of desire building in your womb, almost snapping when he puts increasing pressure onto the soft spot inside your walls that makes you feel like your mind is going to break.

You’re so close, right at the cusp when his long fingers slide out of you, swiftly replaced by his thumb, but it’s only swirling around the surface now, gathering fluid. Annoyed, you buck lightly against his face in an attempt to get him to put something back in you before you lose it, and that earns you a sharp swat to the inside of your thigh, hard enough to make you gasp.

“Don’t be an impatient brat,” Aki scolds, continuing to gather your arousal onto his thumb before sliding up your fleshy cheek to circle slowly around the rim of your ass. Your eyes flash wide open. When you let out a high-pitched sound of objection, Aki soothingly caresses you with his other hand, tracing lazy circles around your aching clit with the tip of his tongue.

“It’s alright,” he murmurs, the low tone vibrating against you as he presses more firmly against the taught ring. “You wanted more, didn’t you?”

Heart fluttering like a caged bird in your chest, you emit a reluctant hum of agreement, even though your hands are flexing nervously behind your back and you feel like you can’t catch your breath. You eventually find yourself starting to relax, melting into the feeling of his warm mouth against you and the tender way he’s stroking the skin of your thigh. When Aki feels you loosen more at his gentle touch, he pushes past the resistance and submerges the tip of his thumb into you, pausing for a moment so you can get used to the intrusion. You groan.

“Not so bad, huh?” Aki mutters between sloppy licks, slowly sinking his thumb deeper. “Relax and let me take care of you.”

When he hears an affirmative moan come from you, he feels his shoulders sink, unaware that he was tensing them. Not holding back any longer, he practically cannibalizes you, licking and sucking on your pussy like he’s starving. His thumb glides in and out of your asshole at a steady pace, making a shiver shoot up your spine and your eyes roll to the back of your head.

It’s relentless, and soon you find your legs shaking uncontrollably, tears flowing out of the corners of your eyes. The black tie in your mouth is a sopping, disgusting mess, you can’t take it anymore and force it out of your mouth with your tongue, a thick string of saliva following it.

“Aki! Wait, please- I can’t!” Your words are no longer suppressed but they’re hardly coherent, wobbly and disjointed from the intensity. “T-too much!”

Uncaring that you’ve managed to un-gag yourself, your pathetic begging only drives Aki to double his efforts. He cruelly teases your pulsing flesh, his thumb showing no sign of slowing down. His mouth is coated, chin dripping with your essence, making it feel like he’s melting into you. It’s ecstasy, the way you taste and the way you’re crying his name. He needs you to fucking cum already so he doesn’t blow a load into his boxers.

Swiveling the position of his hand, he shoves his index and middle finger into your cunt, fucking you with his fingers and stilling his thumb, letting it remain snug inside of you. A strained sound forms in his throat when he starts to feel both of your holes lightly pulse around his digits, knowing you’re getting close. His actions grow more controlled and purposeful, wrapping his lips around your clit and sucking hard, tongue flicking at the swollen cluster of nerves while his fingers scissor inside of you, stretching you more. Finally, you break, a choked wail ripping from your throat as you cum hard enough for black spots to speckle your vision.

Fuck, that’s it. Aki lets out a low groan as a gush of your arousal drips down to his tongue, licking you clean until you’ve finished riding your high, only removing his mouth from your overstimulated flesh when he’s sure the peak of your orgasm has passed. He slows the pace of his fingers when your aftershocks begin to subside. His gaze remains locked on to the way your dripping pussy accepts his fingers so easily, like it’s been waiting for him.

He wonders to himself if it would accept his cock with the same eagerness. In fact, he thinks that if he doesn’t pull his dick out and bury himself in you right now, he might actually die. But, he’s not in his current position due to lack of control, so instead he reluctantly slides his fingers out of you and wipes his mouth off onto the sleeve of his shirt before gently freeing your wrists from the constraint of his belt, tossing it to the floor.

A small huff of laughter leaves his lips when you let your arms fall limply to the bed, clearly not making any effort to lift yourself up or move in any way. Carefully wrapping his arms around your torso, he lifts your form effortlessly, hooking his forearm underneath your knees. He drags you with him as he moves to lean against your headboard, trying not to wince at your weight against his still-hard cock when he sets you in-between his legs, encouraging you to lean your back against his chest. Your panties are still loose around your knees, but you’re so blissed out you don’t care enough to do anything about it.

You sit like that for a few minutes, quietly. Aki idly traces the marks around your wrists, pink and angry from being restrained, trying hard to calm himself down so his dick doesn’t stab into the small of your back. While he’s sure you’re probably exhausted after that, the silence in the room is palpable under the weight of what he’d just done to you, and he can feel his heart start to race, both panicked and stupidly turned on.

His stomach bottoms out when he feels you lean forward, already missing the warmth that slowly leaves his chest from the absence of your body. When you angle yourself to look at him, he swallows. Your face is bright red and your lips are pursed. Warm, glossy eyes continuously darting from his face to different points in the bedroom, like it would be painful if you let your gaze linger on him for too long.

“Listen, this…” Aki pauses, clearing his throat. His eyes soften as he watches you. “This doesn’t have to mean anything,” he continues, expertly concealing the hint of desperation that threatens to bleed through the calm tone of his voice. “If you want, tomorrow we can act like nothing happened. I don’t-“

“Wait- is that really all?” You blurt out, turning to face him fully. Kneeling in between his legs, your hands splay out in front of you as you lean forward, looking at him directly with wide eyes. “W-we’re not done yet… right?” You ask in a small voice, eyebrows creasing. “I haven’t even gotten to…” Trailing off, you glance down at the obvious bulge in Aki’s slacks before averting your gaze again, a furious blush creeping up your neck.

Aki feels like he might pass out.

It was one thing for you to allow him to touch you in the way that he did, but even the vague suggestion that you might want his dick anywhere near you is enough to make him tremble, his erection straining even more.

Wordlessly praying to whatever deity might be listening that his hand remains steady, he reaches out to lightly grip your chin, turning your head so you’re forced to meet his gaze.

Aki’s pupils are so large his irises look like endless voids. They bore into you, threatening to blot everything out. You inhale sharply when his thumb traces the delicate softness of your lips, encouraging the seam to part for him. Pushing past your lips to press the pad of his thumb down onto your warm tongue, he murmurs your name softly, the sound making you shudder.

“Still feeling greedy?” He asks, shoving his thumb further into your mouth. You nearly gag when he presses hard at the base of your tongue. “Then let me use this pretty mouth of yours.”

Before you can say anything, he’s dragging you off of the bed and down to the floor.

Standing tall, Aki looks down at you hungrily. The bob of his throat is almost imperceptible, eyes tracing every inch of you as he undoes his pants.

“Kneel properly. And take that shirt off,” he orders. “Let me see you.”

As you pull your shirt over your head, Aki finds the sheepish look on your face amusing. His face had been buried in your pussy minutes ago, yet you’re looking up at him like a blushing virgin. He knows better, his trained eye falling to the fluttering of your pulse point and the way the rising and falling of your chest has quickened. The corner of his mouth quirks at the image of little hearts forming in your eyes, like one of those dirty graphic novels Denji leaves lying around.

Exposed like this, your nipples harden immediately. It’s different than earlier. Now you have to see his face as he drinks you in, forced to bear witness to the way his eyes darken even further, looking at you like he’s trying to keep himself from eating you alive. A hint of smugness lurks behind the hunger, like he’s getting a kick out of making you squirm.

Kneeling before him, you impatiently push his hands out of the way. Aki stifles a hiss when you begin nuzzling your face against his clothed hard-on, making his cock twitch.

His mind is whirling, a myriad of conflicting emotions battling each other, the strongest one being jealousy.

The way you pull his slacks down just enough to place wet, hot kisses along his shaft through the thin material of his boxers. The way that you tease him, just barely grazing your fingertips along his length while you lavish attention to his balls, the feeling of your damp breath against him making precum dribble from his tip before you’ve even pulled him out.

You’re experienced, clearly. Of course you are. Aki isn’t that delusional to assume he would be your first for anything, let alone something so simple. Shit, even high-school students go further than this.

Still, he can’t stop the intrusive thoughts of someone else being on the receiving end of your practiced devotion, flashes of that damn cop’s face invading his mind. A suffocating flood of anger fills his chest, and in this moment, he truly believes he could bring himself to strangle the life out of Hasegawa if he sees him again.

The feeling of your warm mouth against the bare head of his cock propels him back to reality, his blue eyes snapping down to watch you. He sees your pink tongue dart out to swirl around the sensitive tip, the feeling making him bite back a groan. The soft sound makes you look up at him. Demure, a deviant form of adoration shining through like you want nothing more than to please him.

Aki’s heart twists. You’re perfect.

Tangling his fingers in your hair, he roughly pulls your head back. A sick feeling of possession overwhelming him as he cranes your neck, exposing the fragile column of your throat. Gripping his cock with his free hand, he presses your face closer, smearing a bead of precum across your lower lip.

He’s going to erase the trace of anyone else, even if it hurts.

“Open your mouth.”

There’s a startled look on your face at his sudden actions, but you comply, opening your mouth wide for him and letting your tongue hang out, a string of saliva dripping from the tip.

Fuck.

“Good. Now take a deep breath for me.”

You barely have time to register Aki’s words before he plunges himself into your waiting mouth, the fat head of his cock brutally stretching the tight entrance of your throat, giving you no time to prepare. Gagging violently around him, you try to pull away but his grip in your hair is firm and unyielding. He pushes himself even further inside, only stopping when his balls are pressed up against your chin.

You grab at his thighs in panic, feeling your lungs constrict from the lack of air, unable to make any noise of protest other than a pitiful, wet choking sound. Your silent pleas are met with complete indifference; Aki doesn’t seem concerned in the slightest. He’s not even moving, just holding your head still, watching you intently.

When your vision gets spotty and your ears start to ring, he finally pulls back just enough to where you can take a deep inhale through your nose. Tears of relief flood your eyes, and gushes of saliva pool past his cock to dribble down your chin.

You’re so beautiful like this.

“Such a mess already,” he remarks, keeping his tone indifferent as he lazily starts sliding in and out of your mouth, using your hair as leverage. “Take another deep breath for me, okay?”

Ignoring the sharp noise of protest you make; he shoves himself into your throat again. This time instead of holding you there, he ruthlessly pumps in and out, the feeling of his cockhead being squeezed over and over again making him groan audibly. The sight of tears spilling down your cheeks makes his balls tighten, and he has to pause so he doesn’t blow his load, soft pants escaping his parted lips.

Catching his breath, Aki’s gaze searches your flushed face.

Despite all he’s been putting you through, you’re looking at him so sweetly. Breath coming out in shallow bursts from your nostrils, you warm his cock in your mouth, patiently waiting for him despite your obvious exhaustion. The dark circles under your eyes are more pronounced now and he catches the slight shaking of your bent legs. He’s learned after watching you all this time that you won’t quit, you’ll keep going until you drop. Even if you made a big show of being under distress, calling him names, hitting him even, he’s certain at this point he could do anything he wanted to you. In the end, you would take it.

His gaze softens. What a stubborn girl you are.

Sliding out of your mouth, he crouches down. You’re breathing hard, lips pink and swollen from dragging up and down his thick shaft, shining in the dim lighting. Cupping your face in his hands, Aki wipes a tear away with the pad of his thumb. When you ask him why he stopped, he laughs quietly.

“Come here.”

Pulling you closer, he envelopes you in his arms, burying his face into your neck. He’s holding you firmly, but there’s an unmistakable tenderness in the way his hand slides up the bare skin of your back to cradle the back of your head. Maybe it’s how tired you are, or how weird this fucking 24 hours has been, but something about it brings fresh tears to your eyes. Your trembling body melts into his, and you return his embrace with the same intensity, gripping tightly at his shirt.

Not wanting to be called a baby for crying again, you press your face against his shoulder, but Aki can feel the warmth seeping through the cotton. He clutches you tighter, murmuring into your ear. “I’ve been a little hard on you, huh?”

Even though you shake your head, Aki knows he has. Uttering your name softly, he speaks again, fingertips tracing up and down your side. “It’s alright,” he soothes. “You can get angry. Yell at me, hit me if you want.”

When he feels the bottom of your fist lightly hit his back, he smiles. “Can I see you?” You shake your head again, face still firmly pressed into his shirt. Aki snorts. “Come on, I won’t make fun of you.”

Reluctantly, you relax enough to let him pull you away from his shoulder. Air shoots out of Aki’s nose when you glare at him in embarrassment. Your eyes are red, face wet with tears and drool, hair wrecked from his rough handling. You’re a fucking mess, and his dick has never been harder.

“You are just like a little kid, aren’t you?” He mutters, unbuttoning his shirt fully, shrugging out of it and using it to wipe your face.

“Knock it off,” you protest, trying to crawl away from him. “You said you wouldn’t make fun of me!”

Laughing gently, he grabs your waist to stop you. “Alright, don’t run off.” He plants you right back in front of him, tossing his shirt to the side and lifting his hands in surrender. “I’m sorry.”

Narrowing your eyes at him, your gaze travels across his toned shoulders, trailing down towards his lean abdomen. Heat returns to your cheeks when you land on his very much still hard cock. It’s thick and long, a pronounced vein running along the bottom of his shaft, the tip glistening with a mixture of precum and saliva. The longer you look at it, it seems to stiffen even more, twitching under your scrutiny. Seemingly in response, you feel arousal leak out of you and you quickly clench your thighs together.

You’re forced to tear your eyes away when Aki tilts your face up to look at him, an amused smirk on his lips. Wordlessly, he pulls you closer and crushes his mouth against yours. Worked up and desperate, you devour each other, tongues scraping against teeth, the sound of moans and heavy panting filling the room. His hands find your breasts, squeezing them roughly, almost hard enough to hurt. Pulling away from your mouth, he starts to aggressively suck at your pulse point, making you gasp. Licking a hot stripe up behind your ear, you feel his breath tickle against you when he asks in a hoarse voice. Still want more?

Seconds later, he has you splayed out onto your bedspread, lapping at your needy cunt once more, the panties hooked around your ankles long gone. You’re already soaking wet and ready for him, but he can’t help himself. Spreading your legs as far as they’ll go, he exposes your clit and presses the tip of his tongue firmly against it, moving in tight circles until you’re crying out from pleasure and overstimulation. Sliding two digits inside of you, he stretches you out, adding a third finger when it gets too easy to glide in and out. When he feels your walls start to squeeze him, he abruptly removes his fingers and mouth from you, making you whine pitifully.

Climbing on top of you, he holds himself up with his forearms. His raven hair tickles your cheek when he dips down to murmur in your ear. “I want you to cum on my dick.” Catching your earlobe between his teeth, he snakes a hand down the plane of your stomach to tease at your swollen pussy. “Can you do that for me?”

When you offer him a silent nod, Aki moves his mouth lower to the slope where your neck meets your shoulder, giving you a firm bite. You yelp in surprise; a deep blush sprouting on your cheeks. “Use your words. Tell me you want it.”

“I-I want it!”

“That’s better,” he mumbles, placing soothing kisses onto the angry teeth marks. Retracting his hand from your slickness, he tugs his slacks and boxers down further before gripping his cock and rubbing the angry tip up and down your slit, spreading your arousal and making you shiver.

Extending the arm holding himself up, he’s able to get a better view when he lines up with your entrance, the heat of your cunt luring him in like a siren. He can feel the tips of his ears start to burn, his heart is pounding so hard he thinks it might burst out of his chest and land onto you with a gory plop.

He’s about to fuck you. After countless guilt-ridden nights of fucking his fist to the thought, it’s happening. You’re underneath him, legs spread, eyes dark with need. He doesn’t deserve this, no one does.

His eyebrows shoot up when you impatiently wrap your legs around him, gently encouraging his hips to dip lower. Aki’s cheeks are a light shade of pink when he looks at you with wide eyes, like it’s baffling to him that you would want him anywhere near as much as he wants you. “Come on…” you whine, eyebrows furrowed. “Do I have to beg?”

He’s definitely dreaming.

Setting his jaw, he sinks into you, cursing under his breath when he feels your walls wrapped around the head of his cock. Gasping, you wrap your arms around his neck, lifting your upper back slightly off of the mattress. He breathes out your name. “Fuck- you’re so tight…try to relax so I can fit it all in, okay?”

Even though you’re dripping wet, your pussy is choking him out, and it takes conscious effort to push into you. Aki’s been holding out so long he’s worried it might only take a couple thrusts before he loses it and paints your cervix.

“That’s it…” he soothes, sinking even deeper. Sensitive and worked up from his earlier descent, your legs tighten around his waist and he can hear you whimpering a string of profanities against his ear.

When he finally bottoms out inside you, he can barely hold back the low guttural noise that vibrates in the base of his throat. The way your pussy coils around him is almost possessive, creating its own form of bondage. He could stay like this forever, buried inside you with your arms and legs constricting around him. Your embrace is so tight, he wonders if you’re afraid like he is. Like if he moves an inch the illusion will be shattered and he’ll jolt awake in his bed, drenched in sweat and heart-wrenchingly disappointed.

Taking the risk, he pulls back, dragging his length halfway out before surging forward again. The low moan that comes from you grounds him, solidifying that this is real and you’re not going to dissipate like smoke in his grasp. Laying you back, he tangles his finger into your hair. Harshly latching his mouth onto your neck, he sets a steady pace, languidly thrusting into you. The soft noises you make fuel the fire in his gut, when he feels your nails explore the plane of his back and shoulders he groans.

Biting and sucking, he hungrily bursts the small capillaries along the curve of your neck. You might be angry with him tomorrow, but he doesn’t care. He wants to create a collar of bruises around your throat, proof to everyone who you belong to. No one can give you the things you deserve like he can, he would happily offer you everything he has if it means destroying the opportunity for anyone else to try.

Blunt canines testing your pulse point, something akin to a growl wracks his chest as he starts slamming into you, the tip of his cock kissing the intoxicating sponginess of your cervix with each plunge.

Breathing hard, your nails dig in to the muscles surrounding his shoulder blades. “Oh- f…fuck!” The sound of your voice spurs him on further, pumping in and out of your sopping cunt with enough force to make any words that leave your lips completely unintelligible.

Tearing himself away from your neck, he nips at your lower lip before sliding his tongue between your lips, giving you a taste of yourself. “You’re squeezing me so much…” he murmurs against your lips, the snapping of his hips never relenting. “Feels good, huh?”

All you can do it let out a pathetic whine.

“Loosen your legs for me.”

Feeling your muscles relax slightly at his command, he coaxes one of your legs to release his waist before hooking your knee over his shoulder. Placing a kiss onto your forehead, he pulls back so he can watch your expression as he drives into you even deeper now. You quickly cover your mouth with the palm of your hand, muffling the sharp cries that are forced out of you.

Aki clicks his tongue.

Blue eyes flashing, he unhooks the leg that still remains curled around him and pushes both of your legs so far back your knees are level with your ears, eliciting a shriek from you that your palm can’t conceal. Gaze locked onto yours, he continues to relentlessly pump in and out of you. Filthy squelching sounds fill the space, your pussy is an absolute disaster and Aki can feel your arousal gushing past his cock, coating everything in its vicinity. His balls stick to your asshole every time they slap against you, making his shaft throb.

Your body is bent and contorted underneath him, breasts smashed together from the pressure of your thighs. Having removed your hand to hold onto his biceps for dear life, he can see the way your pretty lips are parted, ragged gasps and moans slipping out with every thrust. You look so deliciously fucked out; you probably wouldn’t even hear him if he were to speak. Strained with exertion and tinged with an almost painful desperation, Aki’s voice floods your ears.

“You- fuck… you’re so beautiful, you know that?” Pressing himself further against you, your clit grazes the patch above the base of his cock. “Drives me fucking crazy.” Halting his thrusts to briefly grind against you, your eyes roll to the back of your head.

“You have no idea how long I’ve wanted to stretch this pretty little pussy out…” Releasing one of your legs, he angles himself so that his hand can snake in-between the two of you, his thumb teasing your worked up clit. His gaze falls, leaving your face to watch the way his cock splits you open over and over again. “Look at you, taking me so well.”

Aki’s praise, the way his cock drags against your walls and the increasing pressure on your overly sensitive clit has you seeing stars. The pleasure building in your core is white hot, spreading up your spine and giving you goosebumps. You can’t even bring yourself to speak properly, the moans coming from your parted lips are lewd and obscene. It’s too much, whatever’s building inside of you, and your eyebrows furrow in panic and pleasure. Trying desperately to form some sort of coherent sentence, you claw at his arms. Clouded with an insurmountable need, Aki’s eyes darken drastically. His expression remains calm and focused, like he knows something you don’t.

“It’s alright. Just let it go,” he coaxes in a low voice, his motions becoming more intentional and tortuous. “I got you.”

Wide-eyed, you look at him pleadingly, an almost confused look on your face. Shaking your head side-to-side, you’re about to beg him to stop when a scream rips through you, barely making its way past your lips when Aki quickly smothers it with the hand that had been holding your other leg steady. Pussy spasming wildly around his cock, your vision goes grainy and your body turns completely rigid underneath him. Another shriek is muffled against his palm when you promptly squirt all over his lower abdomen.

“Holy fucking shit-“ Aki pants, sucking his teeth. He can’t take it anymore. Apologizing in a choppy voice, he grabs onto your hips so hard it’s sure to leave marks and fucks in and out of you at a frenzied pace, making you cry out so loud he’s certain you’ll be getting a noise complaint.

“Fuck- I’m about to lose it,” he warns, brows knitted in concentration. Your walls are still pulsing around him, milking his cock. When your nails gouge into his back roughly enough to break skin, he can’t stop himself from unloading inside of you, letting out a choked groan as he floods your abused cunt with hot spurts of cum. The sensation is overwhelming and your hands fly to fist into his hair, dragging his face towards yours. Your lips meet in a sloppy, languid kiss as he fucks his load further into you, the pace of his hips gradually slowing as the throbbing of his cock subsides.

Trying not to crush you, he hovers above you on his forearms, catching his breath with his face planted into your neck. He places a gentle kiss behind your ear before slowly pulling out of you and lifting himself up. Weakly, you grab at his arms. “Don’t go…”

Aki’s heart swells.

“I need to grab something to clean you up with,” he murmurs, brushing your hair back. “Give me one second, okay?”

Too tired to even open your eyes, all you can muster is a nod.

***

The sound of a sliding door being opened jolts you awake and you sit up in a disoriented panic. Blinking rapidly, you take in your surroundings. Looking down at the plain, off-white bedding pooled at your lap you feel yourself relax a little. You’re in Aki’s room. You feel your face heat up when you realize you’re now in one of his shirts, he even managed to get a pair of his boxers onto you.

“I didn’t mean to wake you,” a soft voice breaks through the silence. Your eyes flicker to the source. Wearing dark sweatpants and a gray t-shirt, Aki stands in front of the glass door that leads to the small patio attached to his bedroom, a cigarette tucked behind his ear.

Clearing his throat, he continues. “You were out cold so I cleaned you up and brought you to my room. I wouldn’t have moved you but I needed to, uh… wash your bedding.” Palming at the back of his neck, a hint of pink spreads across his cheeks. “I’m sorry.”

“Can I come with?”

He blinks. “Outside? It’s cold, are you sure?”

You nod. After slipping out of his bed, your legs are shaking like a fawn and they give out on you almost instantly, you crumple to your knees with a thud. You glance over at Aki with a stunned look, mouth hanging open. When you see him fighting back a self-satisfied smile the skin on your face feels like it’s going to burn off and cross your arms over your chest. “Whatever it is you’re thinking about saying, don’t.”

“Wasn’t gonna say a thing.”

It’s starting to get light outside. Aki can hear the rattling cry of a crow somewhere in the distance, followed by another. Taking another drag off of his cigarette, he watches the tendrils being pulled away with the breeze. He feels you stir in his arms and he tightens his hold on you. You’ve fallen asleep again, bundled up in his blanket and curled up in his lap.

Just like a cat, Aki thinks, wrapping his lips around the filter of his cigarette again. If he doesn’t move a muscle, he can hear the slow, steady rhythm of your breathing. He drinks in your sleeping face, smiling gently at the way your cheek pressed against his shoulder. Still asleep, you nuzzle even closer to him. Something spreads through his chest, syrupy and decadent, like honey warmed by the sun.

He could get used to this.
