⟡ summary:

Who would have thought, Matsukawa Issei, your best friend's best friend, is a demon?

Obviously, not you. But it works out in your favor, even if you're a demon hunter.

Archive of Our Own

It’s a school night, so you should probably head home soon.

It’s a passing thought as you wipe your cheek, rubbing away the black sludge on your skirt. The stench of blood and ash fills your nose as you watch the minor demon melt. It’s shrieking, writhing in pain as your exorcism spell reaches its end.

Its inky tendril reaches for you, but you don’t even flinch, watching it dissolve into the air with a final cry.

A sigh escapes your lips, and you finally relax your shoulders.

The demons around Miyagi have been more active as of late, and it’s taken a toll on you. You’ve been taking longer patrols after school, which means you stay up later into the night to complete your homework before sleeping a restless sleep and repeating the cycle. You could probably count the number of hours you’ve slept on average with one hand, yikes.

You’re tired, to be frank. Thankfully, most of them are lower levels, but they’re a force to be reckoned with when they have power in numbers, and you only have so much energy to take care of a large area on your own.

It’s not like you voluntarily chose to hunt demons. But it wasn’t something you could walk away from. Ever since you began seeing them as a child, you soon found yourself under the local priest’s training, mastering basic exorcism techniques and continuing to practice advanced ones that even the priest struggled to use.

No one else saw what you saw, only becoming a victim to them when they sapped human energy to gain more power. You’re not too sure how they’ve come into the human world, but the priest theorizes it’s some sort of rift that has let them cross the barrier. Closing the rift is a whole different story, and even you’re stumped for ideas, so you do what you can in the meantime.

If you could make someone’s life easier, unburdened and no longer haunted, you would.

It was a thankless duty, but a duty regardless.

You head home for the day, dreading the upcoming exams and the pile of homework that sits in your backpack, completely blank.

“Oh, [Name]!”

The call of your name has you jolting awake at your desk, quickly blinking away the sleep as you look up. “Hiro? What’s up?”

The clay-haired boy enters your classroom, making his way to your desk and sitting in the one in front of yours. For the most part, everyone went off to eat lunch outside since the weather has gotten warmer, which lets you ditch the thick winter uniform for the short sleeve button-up and skirt.

“You said you’d meet me and the other guys for lunch, but you never showed up. And now I find you dozing off– you good?”

“Yeah, yeah,” you wave off, rubbing your eyes. “Been sleeping late the past few nights, but I’m going to try to fix up my sleep schedule this weekend, hopefully.”

Hanamaki eyes you suspiciously, and you stare at him with the same intensity. As childhood friends, you can read him just as easily as he can read you. It’s not often you wear yourself out to the point it's noticeable, but it just can’t be helped and like the workaholic you are, you can always blame it on upcoming college entrance exams.

He gives in with a sigh when he realizes you aren’t faltering, and he shrugs. “Just don’t push yourself too hard,” he says, gently. “You work hard enough as is, and I think you deserve a break with how much you’ve been doing.”

You smile, because you know how much he cares, and you know that he still respects your drive and your own judgment. This also makes you extra careful around Hiro, who would absolutely freak out if he knew you were out hunting demons.

“Yeah. You too, with volleyball. I don’t think your friends would appreciate having two volleyball-obsessed players.”

“Ha! Like I’d ever reach Oikawa’s level of obsession.”

You banter with him a little, your exhaustion melting away as you chat with your best friend before he suddenly stops mid-sentence with a noise of realization.

“Wait! You haven’t eaten anything, right? Since you were sleeping?” he asks, and when you nod, he stands up quickly, ignoring the way he trips over the chair slightly and grabs your wrist.

“Let’s grab something from the cafeteria before it closes! We can probably make it!”

And you run with him down the halls, dodging friend groups and teachers who yell at the two of you to behave.

And for the first time in a while, you smile brightly, enjoying this moment of normalcy.

While you absolutely love Hiro, you find yourself unsettled ever so slightly with his friends.

Not Iwaizumi, since he’s rather respectful and polite, and not Oikawa, since he’s just a flirt whenever you’re around.

But Matsukawa Issei is another story. He is…dangerous, for a lack of a better word.

You find yourself nibbling on a curry bun that Hiro managed to buy from the cafeteria right before they closed. With about fifteen minutes left of lunch, you take him up on his previous offer to eat with his friends, sitting on top of the school rooftop with the four boys as they finish up their lunches.

When you greet them, you can’t help but avoid Matsukawa’s heavy stare. There was something oddly familiar and unsettling about it…something you couldn’t quite put your finger on, and you opted to blame it on the unfamiliarity, or the fact that he’s one of Hanamaki’s closer friends after entering high school.

The idea that Matsukawa stole Hanamaki from you doesn’t sit well in your gut and you chastise yourself for even having that thought. Maybe he thinks the same thing, hence the strange feeling you get whenever you are near him.

You push it to the back of your mind, and do your best to ignore him as lunch comes to an end, heading back to class. It’s uneventful, as always, learning new concepts and putting them to use on your worksheets and later, for exams. It’s mundane, but you enjoy it, since it’s not like you’re actively putting yourself in danger as you normally do.

As soon as the last class ends with the ring of the bell, you briefly replay Hanamaki’s concerned words, before you shake your head.

You’re better than that, you could keep hunting, keep helping , even just a little. It’s a responsibility that you’ve chosen to handle, and you can’t slack off just because you’re a little tired .

It’s ok, you reason with yourself as you pack up your notes. Just a short patrol, and you’ll take time to rest today.

It’s unfortunate that your plans always seem to get foiled, and you eat your words. Literally.

A blast sends you flying, and you think you hit your head against the lightpost before absolutely eating shit on the sidewalk. The demons laughs, it’s screeching noise grates your ears, slightly disorienting you as you struggle to get up. You’re unsteady on your feet and while you’re fully aware of how hard you’re pushing yourself, you can’t just go home, not when the demon presence in this area is just so high.

It wasn’t this bad before. Their numbers keep rising, and your efforts barely make a dent in their forces. It’s a harrowing thought that makes you falter for a moment, but you grit your teeth and steel yourself once more. Summoning another talisman, you launch it at the demon, watching the paper attach themselves to its body, burning through the inky black as it disintegrates. Your limbs tremble, and you ignore the numbness in your legs.

You let out a shaky exhale, but you remain on alert. The air is saturated with despair and evil, and it makes your chest tight.

You’re so, so tired.

Just one more sector. Just a little more and you can end your patrol and go home and get rest.

Just one more–

Thump!

Huh?

Pain sprouts at the temple of your head. You’re staring across the asphalt of the alleyway, the faint silhouettes of demons growing larger–coming closer to you from the street.

Get up, get up!

Yet no matter how much you willed your body to, you lay crumpled, defeated, and tired.

A wave of cold dread washes over you and you close your eyes tight.

I’m sorry, I’m sorry Hiro, I’m–

High-pitched shrills fill the air, and your eyes fly open, immediately lifting your head to see –

“Makki kept telling me he was worried about how tired you looked. Guess this explains why, huh?”

Matsukawa is standing protectively in front of you, but your eyes land on the black, ridged horns that protrude from his messy hair, curling slightly at the tip and alarms blare in your mind.

Matsukawa Issei is a demon.

And you have to kill him.

The thought crosses your mind briefly, but then you look past him, watching as his splayed hand emits another burst of energy that disintegrates the demons at the mouth of the alleyway. They are the ones screaming in pain, they are the ones to die in front of your eyes. Not you.

“Why…” you mumble, because what was this demon doing, attacking his own kind to protect you?

Without a response, he finishes off the last of the small demons who have attempted to escape around the corner, and silence falls over the two of you.

Shit, maybe he’s going to kill you next. Maybe he’s just so cruel to take the kill of a demon hunter all to himself. Without a doubt, he was not some weak troublesome demon–no, he was much, much stronger than those you normally deal with.

He would enjoy watching you die, watching the life leave your eyes in amusement.

You close your eyes tight, trying your best to get up, trying your best to come to terms that you are going to die at the hands of a demon (your best friend's best friend, nonetheless) as you listen to his footsteps grow closer and closer. They stop, and you know he’s standing over you, probably reveling in the sight of your weak, crumpled body.

You brace yourself once more, expecting pain to erupt and bring you to the edge of death.

“Can you stand?” You open your eyes, confusion filling your head. He’s crouched down, hand hovering over your face. The chilling smile of death that you envisioned is erased as you see his eyebrows furrowed as he scans your figure for injuries.

His eyes have a red tint to them that makes you freeze for a moment. He knows fear when he sees it, and he sees it clearly in you as he meets your gaze.

“Y-Yeah. I think so,” you say slowly, shifting to rise. His hands hover over you still as you get to your feet, wobbly, and standing for just a moment before your knees buckle from under you. Matsukawa is quick, arms encircling your frame and catching you before you can hit the ground again. He sits you down against the cold wall, maneuvering you, careful to lean your head back with his hand.

“You’re bleeding a bit,” he points to his forehead, and you swipe at your own, grimacing at the blood. “But you aren’t hurt anywhere else. I’m glad.”

“Glad?” you parrot in disbelief. “You’re glad that I, a demon hunter, am not hurt?”

Matsukawa blinks, before he laughs, soft chuckles escape him and you watch him incredulously because why does he think this is funny? “Yeah, I’m glad,” he says, smiling. “Since you’re the one keepin’ most of them at bay. I try to get rid of ones near the school area, but I usually don’t go any farther out than that.”

“What do you mean you get rid of them?”

He contemplates for a moment, eyeing the entrance of the alley before his eyes flicker back to you. “Maybe we should get out of here and have a chat, hm?”

Never in your life did you expect to find yourself in a demon’s home.

And never in your life did you expect that a demon’s home would be a cozy little apartment nestled in the residential district just ten minutes away from your high school.

To be fair, your life is anything but normal, so maybe this falls into the realm of likely possibilities.

That sucks, you suddenly think, because that means there are more things you simply don’t know about–which isn’t new, but it’s never a good thought to dwell on.

You keep your distance as he leads you back to his place. He lives on his own, having forged fake identities for his “parents” and keeping up the guise that they’re busy with work in Tokyo or abroad. It makes sense, but you’re filled with questions to the brim.

With the main one being, “why?”

He’s back to the human Matsukawa you’ve known for years, the one without horns and red-tinted eyes.

As he unlocks the door, you hesitate for a moment, suddenly imagining scenarios where you’re being led into a demon’s dungeon, that you’d be tortured and your soul would be offered up to the demon king or whatever higher level demon exists and–

“Are you just going to stand there?”

His deep voice brings you out of your stupor, and you’re embarrassed, gaping at him for his casual response–as if he’s just bringing a friend over to hang out. With a stutter of “no,” you enter, wary of your surroundings.

It’s plain, for the most part. Blank walls with minimal furniture fill the home, and everything is relatively cleaned up as you enter deeper. Matsukawa heads to the kitchen as you walk into the living room that has an untouched loveseat in front of a small TV.

“Tea? Or do you want some water?”

“Water is ok,” you answer him, and you take a seat gingerly, setting your bag down and suddenly feeling awkward.

He brings you a glass, and you thank him quietly, staring at it to see if there was anything amiss in your drink.

“It’s water,” Matsukawa deadpans at the sight of your intense stare. “I didn’t do anything to it, if that’s what you’re worried about. I’ll get the first aid kit though, and we can clean up your head before we start talking.”

Watching him disappear to what you presume is the bathroom, you look back at the glass of water before taking a sip, which turns into two, and then two more gulps to finish it off.

As you set down the glass, you see Matsukawa return with a small kit and wet cloth, taking a seat next to you before cleaning up your wound. You bite your lip at the stinging sensation, staying still as he finishes up with a bandaid.

His hand is warm against your forehead, and you try not to let your mind linger on that fact.

“So, where should we start?” you ask, watching him pack up the kit and setting it on the coffee table. He hums, leaning back and throwing an arm over the back of the couch.

“I can start,” he proposes. “I’m a demon, as you already guessed. Was born, if you could call it that, about the same time you were probably born. I never really liked the idea of stealing human energy solely to grow powerful, so I aged slower and stayed under the radar to avoid getting killed by hunters.”

“And how’d you do that?” you ask, because you have to admit, he did a great job hiding his presence the past three years you’ve known him.

Something was always off about him, ever since the day you met him in your first year, where Hanamaki excitedly introduced you to his new teammates.

“Oh, I’m an incubus,” he says offhandedly. “Most of our kind usually don’t stand out in the first place, and it’s much easier for us to mask our scent and blend in with humans.”

“An…incubus? As in, the demons that…” you trail off, realization hitting you like a truck and it hits harder when you see Matsukawa smile.

“C’mon, you can finish that sentence, you’re a big girl,” Matsukawa teases, and you feel heat rise to your cheeks.

“You gain energy from sex.”

“Bingo.”

It takes your mind a moment to process and remember what you’ve learned about incubi. You haven’t encountered one before, to be honest, and you recall that they, as well as succubi, were the rarer types of demons to exist.

Most demons didn’t have a developed sense of consciousness, merely driven by their hunger for more energy, to gain more power with no other purpose.

You’re piecing things together because, yes, it makes sense now how he is so human despite being a demon, how he can retain a human form and not a monstrous blob, and–

“Wait a minute–then, who have you been having sex with–” you shut up the moment the question tumbles out, and Matsukawa laughs again, a deep, hearty laugh that leaves you absolutely humiliated.

“Wow, asking about my sex life already?”

A slap to his arm gets another laugh out of him. You have no doubt he’s enjoying teasing you.

“But, really. It was me and Makki, for a bit,” he says earnestly, and you let out a noise of surprise, but he doesn’t stop there. “No, we didn’t fuck or anything, before you jump to conclusions. We made out and stuff. But lately he’s been talking to that one girl in class 3-B, so we called it off–just a few days ago, actually.”

You feel a headache coming on.

First off, you’re definitely going to Makki and probing him about whatever fling he had with Matsukawa because how dare he not tell you about it.

Second–

“How are you still so powerful if you’ve been just living off…what you have–no, had with Hiro? What are you going to do now?”

“Well, that’s the thing, little hunter,” he mumbles, leaning back. “I used most of my energy on getting rid of those demons earlier, so I’m exhausted.”

You take a moment to mull over his words, and that’s when you realize how there are dark circles beneath his eyes, which was definitely not there before when he first helped you up.

“And it’s not like I’m going to go out and just go to anyone,” he continues after a moment. “I just want to live my life as normal as I can. ”

Whatever unsettled feeling you had in your stomach before is replaced by guilt. You’ve never…communicated with a demon before, and never did you think that they’d have such honest emotions and desires to be human.

“You really don’t want to harm anyone?”

“No,” Matsukawa responds, seriously. “I want to keep all of them safe: Makki, Iwaizumi, Oikawa, all of them.”

“You’re a traitor to your own kind.”

“And I’ll continue being one, if it means I can live as normal as I can.”

You stare at him, looking at his hooded, dark eyes to see if there is any hint of deceit. As suspicious as you were of him, you can’t help but believe him. And what would that do, killing a demon who just wanted a normal life, a demon who was also a dear friend to many?

Hiro would be devastated.

“I’m sorry,” you begin, and Matsukawa’s eyes widen, not at all expecting the apology. “All this time, I thought demons were…evil. But if you’re being honest, then who am I to kill you when you’re just trying to live a normal life?”

“Well, I’m glad that we’ve come to a truce,” Matsukawa says. “Thank you. Didn’t think all you hunters were fine with us, but I really do appreciate that you’re letting me live–I have no doubt you could kill me, even now.”

That makes the both of you chuckle, but soon after, a tired sigh escapes Matsukawa, and you see him close his eyes, and you’re suddenly reminded that he exhausted most of his energy saving your ass.

Perhaps it was obligation, perhaps it was curiosity, but–

Something burns inside you.

The words escape your lips before you can reel them back in, and you’re instantly mortified right as they leave your lips.

“If you need energy, then why not with me?”

You're staring at your hands that are folded on your lap, your entire form tense as you realize what exactly you just offered to him. Silence follows. No laughter, no rejection, no movement.

“Of course, you don’t have to agree–”

“You sure?”

Raising your head to meet his gaze, you’re frozen by the hungry look that he has in his eyes, darkened with an unfamiliar feeling that makes you shiver. You think you see red flash in his eyes.

“I…I owe you for saving me today,” you force out. “And if this helps you maintain your power, then we can maybe… work together to keep everyone safe.”

“I’m asking you again, are you sure?” he says, voice low, making a shiver crawl up your spine as he pushes himself up with his elbow, leaning closer to you.

“I’m sure,” you confirm, swallowing down any hesitation as you face him directly.

He surveys you, closing his eyes and chuckling a bit before he grins, amused.

“Thank you for the meal, little hunter.”

In an instant, he’s next to you, his breath ghosting over your ear, and you jolt in shock and at the sudden heat that runs through your veins. He’s leaning over you, trapping you with his arms and you gulp nervously, letting out a soft noise as his tongue trails along the curve of your ear before he moves further down, licking a stripe up your neck.

“You know, I always thought you were cute,” he mumbles into your skin. “I was surprised when Makki wasn’t into you, but that’s fine, it worked out perfectly in the end.”

His lips latch on, sucking gently, and you moan softly at the foreign touch, absolutely embarrassed at the way he easily makes you melt.

In the midst of warmth, you vaguely feel his large hands trail down your body, before they grasp at your hips and—

“There we go,” Matsukawa praises as he flips you so you’re straddling his lap, your crotch right over his—

“I’ve never done this before,” you blurt out in nervousness, because you most definitely feel his growing bulge through the thin layer of your own underwear.

“That’s ok. We don’t have to go that far,” Matsukawa answers instantly, calming your nerves just a little. “I can get energy from giving, too. Not just receiving.”

One of his hands finds its place on the back of your head, tangling with your hair as he looks up at you, wanting, hungry.

“May I?”

A small nod is all you can muster.

“Tell me properly, little hunter,” he whispers, and you feel a hot flush crawl up your neck.

“Yes, I… kiss me, please,” you mumble out quietly, looking away, and he chuckles.

“As you wish.”

The hand behind your head presses down softly, leading you so your lips are just mere centimeters away from his before he closes that distance.

Soft.

His lips are so soft against yours, his warmth enveloping yours and you hold your breath, clumsy, unfamiliar with this dance. If he notices your inexperience, he makes no comment on it, looking up at you with hooded eyes and licking his lips as he leans back.

“Not so bad, right?”

An affirmative hum escapes you as a pleasant feeling tingles along your skin and further down, and the feelings of embarrassment fade away, replaced with your desires for more.

When you open your eyes, you immediately find yourself looking back at red ones, and you watch as his horns appear from the curls of his hair once more. Upon closer look, they're sleek black, equal ridges traveling up to the very tip that curls slightly.

His lips curve into a smirk that makes you feel smaller, but another part of you wants to wipe that smug look off his face so you lean back in, crashing your lips onto his with a sudden feeling of confidence that surges through you.

You jolt from the sudden feeling of his tongue as it teases your own, and you have to prevent every ounce of your demon hunter instincts from biting it as he explores your mouth.

You focus on Matsukawa, his lips, his hair under your fingers, his hands on your waist, his bulge pressing up against your wet sex.

Fuck , his tongue swipes against yours and you falter, leaning forward when he backs away, a satisfied quirk of the lips. His hand trails to cup your cheek, dipping his thumb into your open, waiting mouth, and you swirl your tongue around.

“Ah, I forgot to mention my spit has some…aphrodisiac properties. But you seem to be enjoying it.”

Your head is fuzzy, eyes glazed as a string of saliva connects you with his thumb as he pulls it away from your mouth. You’re too gone to care about your pride, and the pleasant buzz you feel blurs all your morals.

You don’t even realize that you’re moving your hips, grinding against his growing bulge that makes you nervous and…

Excited.

Something flares inside your chest at the realization.

You don’t know how long it lasts, your tongue dancing with his, hands roaming, exploring everything he had to offer you and you for him. It’s dark by the time he finally pulls away, gently tugging you off his lap as a string of saliva connects your lips to his.

“Thank you,” he says your name, making you whimper, leaning forward to chase after his lips. “You’ve done more than enough for me today. I look forward to working with you, little hunter.”

He licks his lips, and with the little reasoning left in your head, you can’t help but realize how you’re absolutely under his spell.

–

The next few days are strange.

Strange in that, you notice Matsukawa more than usual. On occasion, you would see him with Hanamaki as he greets you when lunch period starts, or when he gets out of volleyball practice with everyone.

Although, something changes after that particular day and you see him in passing as you eat lunch with your classmates, when you head to the restroom, or even when you take some papers to the teacher’s office. He’s just always somewhere in your peripheral vision, intentional or not, as if watching over you from a distance.

Hell, you make eye contact with him where he’s seated out in the courtyard with the other boys and you just so happen to look outside for a brief moment while you’re on cleaning duty.

When he smirks up at you with a wink, you feel warmth spread across your cheeks, suddenly reminded of…

All the events of that day rewind in your head within the span of ten seconds and you grip your broom tighter.

That fucking demon.

Your classmates ask what has you so flustered and you can only sigh and rub at your cheeks, hoping to wipe away the brightening red.

You hope they don’t notice how you squeeze your thighs together ever so slightly.

It doesn’t help that as the next few weeks go by, even your childhood friend notices your not-so-subtle change, and unfiltered as he is, he immediately jumps on it.

“So, you and Mattsun, huh?”

“What?”

You raise an eyebrow at his suggestive tone, and he takes it as a sign to continue, waving around his milk carton.

“Don’t pretend– you and him have been talking more, out of the blue too! And he’s not very discrete, I saw him looking at you a few times,” he mock-whispers to you. “Did something happen? Should I be happy? Or maybe even worried?”

“Neither,” you grumble, because Hanamaki most definitely misunderstands the entire situation but you can’t exactly clear it up. “We just started talking ever since we bumped into each other a few days ago. There’s nothing more.”

“Hm.” He’s looking at you with his usual stare, and you don’t even look up from the worksheet. “If you say so. I’m glad you guys are getting along better.”

You look up to meet Hanamaki’s gaze, but from the corner of your eye, you see Matsukawa chatting with some other students in the hallway, locking eyes with you before sending you a knowing smile.

Getting along is one way to put it, that’s for sure.

Just a few hours after that conversation with Hiro, you find yourself pushed up against the wall of the boy’s volleyball club room, moaning softly as he peppers open-mouthed kisses down your neck and grinds his thigh up against your sex.

“Ah–Don’t you dare leave any marks,” you gasp, shamelessly moving your hips for more friction against him.

“Or else what?”

His teasing voice has you throwing your head back, and the trails of his saliva burn deliciously along your neck. Matsukawa’s hands trail up your waist before they cup your tits, squeezing playfully.

You have no retort for him, opting to quiet down – practice is soon, and he has dragged you into the lesser-used clubroom to “recharge.” There’s a chance that anyone from the team could come in, knowing your terrible luck, and the thought makes you both humiliated and excited, to your horror.

“Just a little more,” he mumbles into your skin, and you’re lost in his dance, brain turning to mush as heat overwhelms you. You’re half frustrated as Mattsun refuses to go any further, edging you on and bringing you so close to your peak before pulling away.

He lets you go, letting you stand on your feet before leading you towards one of the plastic chairs, sitting, before tugging on your waist so you sit in his lap, back against his chest.

“What are you—”

“Shh, not too loud,” he whispers, licking at the shell of your ear before nibbling at it, as his hands unbutton your blouse. You don’t even stop him, grasping at his forearms as you feel the fabric of your shirt pull away.

“Open your eyes.”

You don’t even realize you have closed them. You crack open your eyes, as he commands, and you see yourself through the full-length mirror that’s hung near the empty lockers. Your blouse is opened, revealing your bra, and one of his hands is lifting up your skirt, legs spread and revealing the soaked patch through your panties as they rub against his bulge.

“Such a cute little slut, don’t you think?”

Locking your eyes with his through the reflection, you turn red at the sight of his smirk, and when his tongue darts out to lick the shell of your ear, you throw your head further back, shivering under his touch. A hand travels up your torso, and you squirm at the ticklish feeling, before letting out a choked moan as soon as he cups one of your tits, squeezing playfully, before pushing your bra up with his hand. His finger teases your nipple, pinching it gently and eliciting more muffled moans out of your pretty lips.

His hips grind up to match your own movements, and he hums, his hand on your hip trailing down to your clothed sex, rubbing small circles at your clit. It makes your hips jolt, shaking as they try to match his pace and he lets out a chuckle against your ear.

“Wait–I’m–”

“Go ahead, cum.” His low whisper tips you over the edge, heat bursting in your gut as you cum against his fingers. The fuzz of your orgasm fills your brain and you’re boneless against Mattsun, who lifts his fingers to his mouth, and you hear him suck on them.

He sits you down on one of the chairs before he fixes his uniform, and you’re sitting there, dazed, the scent of Matsukawa lingering in your nose, his taste still upon your tongue.

More, more, more.

Matsukawa looks back at you, a satisfied smile on his lips.

“Practice is starting so you won’t have to worry about anyone coming in anytime soon. I’ll meet you after?”

You hum, not trusting your words to come out. He grins, leaning down to peck your lips one last time.

“Good girl.”

A promise is a promise, but you don’t know how you can keep going with his teases.

That fucking demon.

–

For the most part, the doubled power makes your patrols much easier, and you feel better about going out without pushing yourself to the edge. Matsukawa’s powers aren’t the strongest, objectively speaking, but the extra hand and cooperation makes your strength combined something to fear. The areas that you’ve left to simmer and grow are much more maintained, and you’re able to make good progress that even the priest comments on when you visit him occasionally.

Of course, you don’t tell him about your partnership. You’re not sure if it would be received well, and you’re not willing to take that leap.

It continues like this for awhile, and you can finally catch up on sleep, even getting a thumbs-up of approval from Hanamaki when he sees you more lively than usual.

But…

There’s something darker in the air today.

It had been a few weeks since you’d nearly met your end. Most areas have lightened up in terms of activity, but for some reason, you feel a chill in your bones that makes you uneasy all day. Matsukawa must have also felt it, glancing at you with worry in his brow.

It’s overcast, and you smell the incoming rain as you tug on your coat, pulling the hood over your eyes as you walk past some high schoolers heading home. Matsukawa is unbothered, merely looking over and nodding to them as they pass.

Practice was canceled a little earlier than usual, so you decided to take an alternate route that goes a bit further from your usual patrol while it was still evening. Rain begins to fall, splattering on the pavement at your feet, and you sigh annoyed. Mattsun breathes out of his nose, a soft exhale as he looks up to the sky. Suddenly–

He stops, whirling around to face the end of the street you two are crossing.

“Get ready.”

“What?”

Your question is answered too soon.

Something crashes, and you jump in surprise, losing your balance as the ground trembles beneath you. Matsukawa catches you, holding you steady, eyes glued to the particles that center together at the end of the street, forming together into a dark blob and taking shape.

It’s downright ugly and terrifying, exuding such malice and rage that has you stepping back. The demons you’ve dealt with before are absolute small fry compared to his massive size and aura.

“What is that?” you shout over its screeching and Matsukawa grimaces.

“A goliath,” he says, a little too calm in your opinion. “Said to be servants of the underworld, or something. I think they consume other small demons, just for energy.”

It roars, a large arm protruding from its back and you recoil in disgust. It is, by far, the largest demon you’ve encountered up until now, and you have no doubt it’s the strongest.

“Ok, well, what the hell is it doing here?” you yell at Matsukawa, who jumps back at the sudden tremor it emits.

“No idea!” he shouts back at you. “Be careful!”

There’s not much room for you and Matsukawa to fight–the street is narrow, and the beast in front of you nearly takes up the whole width. You keep your distance, making sure you’re not in its reach as you launch a few talismans toward it, maneuvering them so they cover its body. Matsukawa approaches it, launching his own attacks as he weaves between each swing of its ugly limbs.

It’s slower than you imagined, and you think as long as you keep your distance, it should be fine–

Dark static flicks off its skin before it explodes in an instant, shooting uncontrollably before it bursts wildly, covering the ground and traveling towards you.

“Watch out!”

You’re shoved to the ground, watching a strike pierce through Matsukawa, in midair as he jumps right where you were.

“Matsukawa”

You see him go down, blood splattering against the asphalt with a sickening sound as his body hits the pavement, hard. Anger fills you with red, and you cast most of your talismans towards the demon, binding it tightly with your power as it screams. It’s stunned for a moment, disoriented as it recovers, but you take the time to run towards Matsukawa, who’s struggling to get up onto his knees, blood dripping from his torso, washing away on the asphalt with the rain.

��Let’s get you out of the way,” you say hurriedly, throwing his arm over your shoulders and dragging him to an alleyway. “Don’t move, you’ll open your wound up.”

As soon as you set him down, the demon screeches, an ear-piercing sound that makes both of you falter.

Demons aren’t perfect. They’ll die with enough damage, and you do so, dwindling down their health with continued attacks, moving constantly to avoid its electricity.

Left, right, under–jump!

You can barely catch your breath as you dodge its movements, careful of where you end up. A screech erupts from its head, piercing your ears, and you take the moment to send more binding charms, tying its limbs together and buying you time .

It struggles, and just as you’re about to blast it with more of your attacks–

A large burst of energy shoots at him from behind you, slicing the goliath’s head off with a clean schuck!

It thuds to the ground, lifelessly, and you’re gasping for air, falling on your ass as it rolls just a few feet away from you.

Matsukawa is peeking around the corner of the alleyway, leaning against the wall as he sends out that last burst of power before he’s sliding down, falling against the brick wall. Without hesitation, you hurry over to him, nearly tripping over your own unsteady feet as you crouch beside him.

Blood spreads across his clothes, a pool of red that makes your hands shake because it’s just so much blood, demon or not. Your eyes flicker up to his, dull and unfocused as they glance up at you.

You tug up his shirt, trying hard to ignore him flinching out of pain to see a deep gash across his stomach, one that curled around his torso, and you have no doubt it probably pierced through him.

The first thing your mind goes to is—

You smash your lips on his.

You taste copper.

He yelps a little at the sudden force, and you cup his cold cheeks with your hands, kissing him deeply.

There’s not an ounce of shame because you’re saving his goddamn life right now . He’s quick to respond, kissing back and groaning against your lips, and in a few moments, his wound is gradually closing up, his blood-coated skin patching itself together.

When you back away, he winces, looking down at his wound, blood and spit smudged against his lips, and you have no doubt that you look the same.

Shit , you think to yourself, feeling a wave of warmth hit you suddenly. And it’s different today because you just want more for once. Perhaps it’s the adrenaline, perhaps it’s because you almost lost him. You’re tired of constantly being edged by him, when you know he could give you so much more, that you could give him so much more.

“Your place is close, let’s get out of the rain.”

Curse Matsukawa for his height. He easily towers over you, and it makes it ten times harder for you to properly support him as he leans against you, his arm thrown over your shoulders as you weave through back alleys, slowly making your way to his apartment. It doesn’t help that the rain hasn’t let up, drenching both of you.

He’s lost a lot of blood, and you’ve been trying to keep him conscious with little success, as he keeps blinking in and out. By the time you’re at his front door, he’s awake enough to dig through his pockets and give you the key with a shaky hand.

There’s blood on it, and you wipe it away with your thumb as you jam it into the keyhole, quickly twisting and opening the door, stepping into the hallway and navigating to his room.

You kick open his door, feeling your strength falter at the sight of his bed and with one last burst, you unceremoniously drop him on top of his covers. He lets out a grunt and laughs a bit under his breath.

“How romantic,” he chokes out, and he rolls onto his back painfully, groaning as he twists his body, mindful of his healing wound.

“Shut up,” you mutter, taking off your coat and kicking off your shoes, slamming the door closed after a moment. Taking in a breath, you steel yourself before you lean on the bed, one knee first, before you swing your leg over his, straddling his lap.

Without any warning, you lean in, kissing him, grinding your hips down on his. You moan against his mouth and–

“Let’s do it, this time, c’mon,” you moan out impatiently, nipping at Matsukawa’s neck as he grabs your hips, tight enough you’re sure you’ll be bruised by the end of it.

“You sure?” he asks softly, lacking his usual teasing lilt, and you nod.

“I’m sure,” you reassure him, looking him dead in the eye, watching as his horns grow out. “I’m saving your life and I’ve wanted to do this with you for a long time. I think it’s a win for both of us.”

He grins, pained, but absolutely ecstatic, as if he’s won the lottery.

“You’re telling me we could have done this earlier?”

“Stop talking and we can get right to it, you dumbass.”

And you can’t stop the curse that leaves your mouth when he flips you over, trapping you under his arms. He tugs off your shirt and your pants, kissing you before you reach up to return the favor. His torso is red, but there’s no longer open flesh that makes you sigh in relief.

At the sight of you bare to him, he leans back, admiring the view and whistling as his eyes trail down your body.

“Can’t believe I went slow with you when you’ve wanted this too,” he comments, leaning to press kisses against the inside of your thigh before he leaves a long kiss on a spot and bites hard . You yelp at the sudden pain, gripping at his hair as he licks his new mark, thighs trembling as he continues to mark you up.

His fingers reach up, hooking under your panties before—

Rip!

“Hey!”

“I’ll buy you new ones,” he says, uninterested, eyes locked onto your cunt instead. “You’re so fucking wet—and all for me.”

He swipes a finger up your leaking pussy, earning a yelp from you and he brings it to his lips, sucking on it

“Sweet,” he whispers. “Didn’t think you’d taste so good, and it’s all mine .” He leans down, spitting on your cunt before licking a long stripe at your folds as you keen, your hands once again finding purchase in his wet hair, tugging at his curls as he makes a mess of you. Your back arches as his tongue flicks at your clit, swirling around it before thrusting in, wanting to taste all of you. His fingers make their way beside their tongue, and he’s pleasantly surprised with how you take one, two fingers, then three as you sing so beautifully.

Your eyes are glazed over, purely lost in pleasure and everything is so hot and you just want his cock so bad and—

It’s coming it’s coming I’m coming—

“Issei!”

The cry of his name makes him smile against you, as you're suddenly hit with a mind-numbing orgasm, back arching and body trembling against his mouth as he continues to coax more you have to offer him. Coming down from your high, you’re far from satiated, still feeling the wanting burn deep in your gut.

You don’t notice him taking off the rest of his clothes until you feel him press up against you. He pushes up your legs, your thighs pressing against your stomach as he leans close and folds you to his will.

He’s huge, you realize, and you’re not sure if he’ll fit, feeling its weight as the head of his cock kisses your pussy. You jerk at the feeling of him rubbing his length against your wet folds, his eyes trained on the way his cock glistens against your wet cunt, slapping it once, twice against it.

As if reading your mind, he offers a reassuring smile, squeezing your thigh.

“Tell me if you need me to go slower,” he says. “Last thing I want to do is hurt you.”

You nod deliriously, moving your hips and rubbing against his length, urging him to hurry up. He finally obliges, pushing in slowly, and you let out a broken moan, clawing at his arms as he groans, sinking into your heat inch by inch.

“Fuck, you’re tight,” he grunts, and he listens to your breathing, waiting for any indication of pain before he keeps going until he bottoms out, hips flush against your ass.

You’re just big, you want to retort, but you can’t even form words, choking on your spit as you feel so full, turning lightheaded at the feeling of his cock stretching you out wide. He’s holding back, biting his lip and a furrow in his brow as he lets you adjust, barely able to control himself.

He’s careful, his calculating gaze roaming over your face as you focus on leveling your breathing, letting yourself relax before–

“Issei,” you moan, “Move, move. ”

He wastes no time, starting slow and experimentally he moves his hips, pulling out of you until the tip of his cock is inside you before he snaps his hips, making you scream as he buries himself to the hilt once more. The bed frame creaks with each thrust, and you whimper, his cock reaching depths that even you weren’t aware of, your walls fluttering around him.

You chant his name, lost in pleasure and Issei knows you’re long gone, completely undone by his cock and his punishing rhythm. He shifts, leaning down to swallow up your moans, tasting you, relishing in your sweet, sweet flavor as you cross your legs behind his back, bringing him closer, deeper inside.

“Let me cum in you,” he grunts out, not slowing down as his dark eyes stare at you and you feel as if he’ll devour you. “Make a contract with me, I’ll be yours, little hunter, just say the word, and I’ll give you my all.”

“Please!” You cry out, nails digging into his back as you hold on for dear life. “Cum inside, I’m yours, I’m yours—“

Your words flow out of you as the knot in your stomach builds quicker as Issei’s unrelenting pace seemingly gets faster and faster.

“Issei, ‘sei, please, please more—faster!”

“Fuck!” he curses, feeling you tighten up around him. “Gonna cum inside your pretty fucking pussy—”

He pushes as far as he can inside you before he stills, moaning against your shoulder as you feel yourself reach your peak, clenching around his cock.

Something warm burns in your abdomen, and you look down dazedly, seeing Issei’s cock buried deep inside you and a strange symbol etched on your skin, just below your belly button. Your hazy mind barely registers the shape, feeling it tingle along your skin.

You feel yourself twitch as he pulls out, a small moan escaping you as you feel his cum leak out of you. He collapses beside you, absolutely spent, and you turn to look at him, brushing a hand through his messy hair.

“Are you ok?”

“Now I am. Thank you, master .”

“Wha– What do you mean?” you ask, flustered, and he laughs, grabbing your hand against his cheek and squeezing it before he trails down to your stomach. His thumb brushes over the mark, and he opens his mouth, sticking out his tongue for you and the same mark is drawn on it.

A contract.

“I’m your familiar now. So, please, treat me well,” he says your name, voice deep with want. The coil in your gut tightens, and you meet his red-eyed gaze. His lips meet yours, and you yelp when his fingers find your tit, pinching lightly. “I’ll treat you well, too.”

“She My Best Friend, Yeah We Not a Couple.”

Synopsis. You know it’s wrong to fuck your best friend. But how can you complain when you’re slammed against the library desk and stuffed full of his big cock like this?

Pairing. Multiple x Reader

Content. MDNI, fem! reader, unprotected sex, panties in your mouth (+ some other very heinous things), really fucking dirty, public sex, jealous sex (from his side), pet names (my angel), swearing.

Word count. 1.3k

A/N. My ancestors are prolly so proud of me rn. Art by @_3em on X.

“Best friend” his ass.

It’s laughable really - the way those other losers think they have a chance with you when you’re begging for his dick every night.

He’s known you since you were both whiney, snot-faced brats - and right now he’s got you sitting prettily on his lap in a study room tucked on the campus library. Your needy mewls are muffled into the crook of his neck as he holds you steady by your hips, the length of his achingly hard cock nudging the line of your ass.

Panties hastily pulled to the side, your slick pools on his flushed tip, dripping along his length to his tight balls. Pressing hot, open-mouthed kisses along your racing pulse, he drags his hefty erection teasingly along your dripping folds.

God, he could feel the way your pussy was clenching desperately around nothing and it was driving him insane.

Surely that study buddy of yours could wait a few minutes. Who did that scrub even think he was? Eyeing his pretty lil’ best friend like that.

“Hngh- please, I want-.” you whisper into his ear, the heat of your breath sending blood rushing straight to his already rock-hard cock. Your needy whimpers are cut off as he subconsciously thrusts in-between your swollen folds, juices making the prominent veins along his length glisten.

Fuck, this was getting too much for him too.

“Tell me what you want, my angel.” he leans down to murmur raspily in your ear, sending a trail of goosebumps down your spine. You were so fucking hot.

That scrub couldn’t even imagine this. How perfect you were. How wet you were for him. How lustful your voice is as you sinfully whine, “I want your cock in me so badly. Want you to fuck me right here. Right now.”

With lightning speed, he’s got you bent against the cold surface of the library desk, painfully hard cock throbbing under the thin material of your panties. You gasp as his length grinds against your quivering cunt.

Having you splayed out so sinfully for him, he’s never been more thankful that the old librarian was such a heavy sleeper - probably wouldn’t wake up for a stampede of elephants if it happened.

“This shit is getting in my fucking way.” he groans out as a large hand grabs your soaked panties.

A sharp rip! of fabric sounds throughout the still air of the study room. “Much better.” he grins dangerously, harshly groping every inch of skin now laid completely bare for him.

“Please. Put it in.” you mewl, voice dripping with need for him. Fuck, he’ll never get used to this.

“Shhh, my angel.” with a low hiss, he bullies his thick cock into your dripping cunt.

“God. S’tight, so tight. Pussy so desperate for me hah- sucking me back in. She doesn’t want me to leave, huh?” he grits out through strangled moans as he sheaths himself completely into your wet pussy. Shit, at this point they’ll hear him and not you.

Warm walls squeezing him to insanity, he fucks you at a feral pace, pulling out till his tip teases your dripping entrance, only to ram himself fully inside once more.

“Ah! Hngh- It’s too much. Please!”

He would never get to know the feeling of your snug cunt desperately sucking his cock back in every time he rams into you. He would never get to feel the way your walls clamp down on him, struggling to adjust to the burning stretch of his thick cock. He could never make you feel this good.

That loser probably has a small dick anyway.

He drinks in the pornographic ah! ah! ah! leaving your mouth at each harsh thrust, feeling intoxicated off the animalistic cadence of his hips, and the thick white ring of slick forming at his base.

“Shit. Always so good f’me, my angel.” he groans, your pretty moans only making him thrust impossibly deeper in a way that has you scrambling to hold onto the table for support.

His throaty groans and the merciless slapping of his heavy balls against your ass echoes across the room as his fingers dig deep purple marks into your hips.

“S-someone’s gonna hah- hear-”

“Then we must be quiet, hm?”

Before you have a chance to process what’s happening, the wet panties that were tightly gripped in his hand are now stuffed into your mouth. You moan around the large fingers forcing themselves inside, cold rings stretching your mouth as much as your cunt.

His cock twitches as he forces you to taste yourself, feeling you getting impossibly wetter. That’s his girl.

He could never fuck you like this.

Moans now muffled by the fabric in your mouth, his saliva-coated fingers move down to draw rough circles on your clit - making you yelp at the stimulation.

He knows someone could walk in at any moment - and a part of him actually wants it to happen. Let them see, he thinks. At least then those fuckers would finally take a hint.

A soft whine of his name snaps him out of his pussy-drunk thoughts, blown-out eyes now meeting your dazed ones as you lock eyes with him over your shoulder. Lipstick smeared, tears clinging to your lashes, and panties half-hanging out of your kiss-bitten lips.

Ah, actually scratch that - he’s gonna keep his pretty lil’ best friend all to himself.

“Shhh, my angel. I’ve got you.” he towers over you, pressing a trail of kisses up the curve of your spine before angling your neck to attach his lips with yours. He delights in your surprised squeal, clearly not expecting him to kiss you with your panties still in your mouth. But for you, he’d do anything.

Cock twitching, your feet almost lift off the ground as the rhythm of his hips gets harsher. He intertwines his tongue with yours, sweet slick-soaked panties wrapped in the middle. Fuck, he was going insane at the contrast of your soft tongue with the lacy fabric of your panties, hand around your neck getting tighter.

You moan incoherently as he sucks on your tongue, drool dripping down the corner of your mouth and onto the polished library desk.

It was so fucking lewd. Doesn’t matter how many losers swarm around you - none of them deserved you. None of them could fuck you like this.

Your sounds of pleasure get more and more frantic as his cock still slams inside you relentlessly, ringed-fingers continuing their abuse on your clit - getting closer and closer to what you crave.

He can feel the way your walls flutter so snugly around him. God, he’s so fucking turned on that he doesn’t know whether the heartbeat he feels between his legs is his or yours.

Neither of you have to wait long. His tongue still continues its dance with yours, around your soaked panties, as you both cum with a muffled moan.

Your pussy clenches around him as you climax him as if to milk his cock for all he’s worth. And you do, thick ropes of his hot cum painting your pulsing hole white.

Riding out both your highs, he fucks his cum into you animalistically - feet lifting off the floor at his firm grip on your waist and the sheer power of his rough thrusts.

So messy. Damn, he has to send the librarian an apology gift later - a fruit basket or something, he wonders, barely lucidly.

His mind is still foggy as he pulls his sensitive cock out, and pockets your panties for a lonely night without his dear best friend. Promptly plugging his fingers in your quivering pussy, cum smearing on his fingers, he mutters out a quick “Keep it inside.”

Walking out of the heavy, sex-filled atmosphere of the study room, he bumps into that fucking study buddy of yours - running late and clearly surprised to see him there.

With a slow smirk, “Sorry in advance, my girl made a bit of a mess in there. Hope you don’t mind.”

Hey, this is what best friends are for, right?

let's go to the beach (beach) [18+]

[ kinktober 2023 ] day 3 - size difference

⟡ haikyuu!! -- matsukawa issei x reader

⟡ wc: 3,137

⟡ working from @/darling--core's kinktober list! NSFW, 18+ only!

⟡ summary:

Matsukawa gets over you once he graduates.

Little did he know you would follow in his footsteps, and this time he'll be greedy.

Archive of Our Own

Matsukawa Issei doesn’t know what to think of you when you first meet.

You’re a cute first year who joins as the team’s manager, and sure, he has a cute innocent crush on you because you’re just so sweet and kind to him, but he doesn’t pursue it knowing he’s graduating in less than a year.

He thinks it’s unfortunate, hugging you tight to his chest as you congratulate him on the day of graduation, surrounded by spring cheer and raining sakura petals. Maybe he holds you for a second longer than it is socially acceptable for friends to hug, but you seem to welcome it, clinging to him tighter as if to keep him there, with you.

He lets go, regretfully, and he doesn’t say anything more.

And then, he’s off to college, letting go of all of his little fantasies and expectations that featured you as the main actress.

Time passes. The familiar song and dance repeats and repeats and he finds himself back on campus for his third year of university. He’s gotten through with new little crushes and hookups and learned more about himself and reality as he barely juggles his academics and life at the same time.

You’re almost completely gone from his mind. It’s always hard to forget the first ones, but he’s ninety-nine percent over you.

What he doesn’t expect is for that one percent to hit him back, hard. As in, you barrel into his life once more, grown up and so much more confident than you before as his meek, quiet junior. And how could he ignore you, when you call his name with that same sweet voice, looking up at him with your big doe eyes as you smile so brightly at the fact that Matsukawa attends the same university as you.

He can’t say no, and the story repeats once more with a few revisions.

Matsukawa loves volleyball, but it’s not enough to chase after a regular spot on the school’s team, so he settles for joining the much more casual intramural league. It’s not hard for you to tail behind, taking up an organizer’s position per his suggestion.

Despite the two year difference between you, friendship comes easy to you as it does breathing. There’s only a slight awkwardness that lingers when you officially meet up for the first time, but once he pats your head and smiles at you, the one where his eyes crinkle and he looks at you gently, you realize it’s the same as before.

Of course, some things are different now.

(His mind wanders more often than not though–he can’t help it, not when you’re wearing that skirt and sweater combo that makes your legs look amazing.)

But now, he finds himself in a study room, nestled in the halls of your dorm building as he watches you work on your essay, jotting down notes to the side as you furrow your eyebrows in concentration. In front of him, his laptop is open to his latest assignment and he has only skimmed through the instructions, favoring the view across the table in the form of you.

“Oh, are you going to the intramural’s retreat next weekend?” you suddenly ask, looking up from your papers and locking eyes with him.

“Hm, not sure yet. I saw that forms were due by tomorrow though. Are you?”

“I think it’d be fun! Plus, I finish up my midterms early next week, so it’ll be like a little reward!”

“Heh, if you pass them,” Mattsun jokes, and you slap his arm with an offended “hey!” He recoils, acting as if it hurt. “Ouch, with that strength, you should’ve joined intramurals.”

“Just fill out that Google Form. I’m passing them and we’re going.”

“Yes, ma’am.”

—

Matsukawa already feels blessed enough to have seen you in casual clothes. Sure, the Seijoh uniform was cute and all, but the tracksuit for volleyball practice wasn’t the best outfit to show you off. Entering uni, your outfits were various and plenty, showing off all your sides. His stare lingered far too long on you when you weren’t looking, desperately burning them into his brain.

But this—he wonders what good karma he had done to deserve this.

You’re in a cute pink bikini, one with white frills around the edges that makes you look so, so sweet. Fuck, the universe is testing him, and he’s pretty confident he won’t pass.

“Mattsun! Over here!” You wave him over, clutching your tote bag closer to your side as you wait for him to reach you. “So? Isn’t it cute?” You twirl around once, graceful, as if you’re in a ballgown rather than a bikini, and he has to avert his eyes when he answers, too distracted by the cut of the bikini top along your cleavage.

“Cute. Is it new?” he asks, and it’s a safe question that he thinks of in a split second. Thank god he didn’t voice his thoughts out loud, or he would’ve been done for.

“Yeah! I got it before the semester began and only wore it once for a pool party!”

A few intramural members pass by, cheering as they rush through the sand towards the water. They nudge at Matsukawa, and you take his hand. “C’mon! They’re leaving us behind!”

He follows you, dragged helplessly by your gentle tug and his eyes locked on the way your fingers are laced with his own. It’s another image—a feeling that he tries to etch into his mind, rather than the blue sea just a few feet away.

You don’t stop, slowing slightly to drop your bag next to the other organizer’s beach towel and you continue your sprint, urging Matsukawa to run beside you as he simply laughs. A shriek escapes you as your feet hit the water, the cold splashing against your legs as it reaches you mid-thigh. You clutch his arm to your chest, and his own heart rate spikes at the feeling of your plush chest.

You’re talking about finding seashells and whatnot, but all he can focus on is the way your bikini fits your ass, how he could swipe a finger and tease your folds and make you a mess in just mere moments. Crouching down, you start to reach into the waters, searching through the sand for anything of interest, completely oblivious to Matsukawa’s inner conflict. You look back at him briefly, noticing his pursed lips, his eyes trained on you, but not quite your eyes.

And then you see the bulge in his swimsuit. Your heart jumps to your throat, and for a split second you wonder if it’s just because of the water rippling around his hips that causes his swim trunks to look like that–

Nope. nope. It’s not just the water, it’s not just your eyes playing tricks on you.

He blinks, and then his eyes flit to yours, following your gaze and he suddenly coughs into his fist, averting his gaze and lowering himself slightly into the water.

“S-Sorry. It’s nothing.”

Part of him hopes you just turn away, but the other part of him, needy for you after all this time, hopes you don’t.

Actually–Fuck it, he’ll make the first move.

He steps forward, one, two, and he’s just centimeters away from before he’s pressing himself against you. You jump, ready to whirl around but he grabs your hips to stop you from moving.

“Do you feel it? What you do to me?” Matsukawa says lowly, pressing your hips closer to him. It’s hard against your ass, and you’re trying to calm your nerves.

You won’t let me run away from you again.

“W-What do you want to do about it then?” You ask, with a flare of confidence that fills you as you experimentally grind back against him.

His eyes flicker between you and somewhere past the shoreline, and this time, you let him take your hand.

——

“Wait—Mattsun—What if someone comes in?”

He kisses you deeply once again, tongue swiping against yours as he swallows your moans and pushes you back against the wall. His breath ghosts over your lips. “No one’s going to come in, don’t worry your pretty head.”

“But–” He shuts you up again, easily overpowering any attempt of you pushing him away as you melt into his hold, jolting with a muffled moan when his fingers find their place in between your legs. They find your clit quickly, his index and middle finger circling around the sensitive nub, making your hips jolt as you grasp at his forearm. Moans fill the empty changing room—the ones that are farther away from the parking lot—but the possibility of someone coming in makes you more excited, much to your horror.

Matsukawa doesn’t seem to mind by the way his swim trunks do a poor job of hiding the bulge between his legs, and as a wave of excitement washes over you, you reach for the hem to pull them down.

Your jaw drops.

Faintly, you remember the times when the Seijoh boys would joke about dick sizes and what not as they left the locker room back in high school, and one of the most memorable points of that conversation you recall is that Mastukawa was, according to Oikawa’s words, “unfortunately, most hung.” You remember slapping Oikawa for being indecent, and Iwaizumi slapped him much harder to echo your sentiment.

He wasn’t lying.

“That won’t fit.”

“Don’t give up until you’ve tried,” Matsukawa jokes, one of his hands coming up to comfortingly pet your hair. “But if it really scares you, we don’t have to go that far.”

“No… I want to,” you reply quickly, eyes still glued onto his length. The tip is flushed red, and all coherent thought escapes you as your eyes trail down its length. You reach out for it, hovering over it and ask, “Can I?”

“Go ahead, princess.”

The pet name makes you shiver. And you wrap your hand around his cock, feeling it warm under your palm and fingers, a wave of satisfaction washing over you as Mattsun groans and closes his eyes in response. You’re barely able to wrap your fingers around it, and you experimentally stroke it, pleased when his hips stutter and he leans down to press his lips to your hair.

“Fuck, princess, keep going,” he groans, his voice a low rumble against your forehead. Spurred by his response, you go down to your knees, looking up at him through your lashes. You continue your ministrations, leaning up to press a kiss to the head of his cock, and Matsukawa moans at the sight.

“Shit, can’t believe you’re so naughty like this,” he says, watching you press another kiss to his length, tongue swiping over it as you lick the pearl of pre-cum off the tip. “When’d you learn to be so lewd?”

“When you left,” you breathe out. “Didn’t want anyone else, only you.”

Something burns inside Matsukawa when he hears those words—you’ve saved yourself just for him, followed him to his university, and it’s safe to assume it’s because you’ve always felt the same way for him.

He feels like he’s won the lottery.

You take his cock into your mouth, fisting the length that you can’t fit past your lips, and he grins, wide.

“I can’t wait any longer,” he hurries to say, cupping your face and gently pulling you up to your feet again. “Next time, I want you like this. But I need to be inside you, now.”

You don’t argue back, instead, nodding eagerly as you lean over so your hands rest against the bench edge. His hands find your hips easy, and he ruts against you automatically, his cock fitting perfectly against the curve of your ass, aching to be inside of you.

“Tell me when to stop,” he whispers against your shoulder. “Be honest with me, I don’t want to hurt you, alright?”

You look up, meeting his gaze through the mirror. His eyes are hooded, filled with lust and hunger, but he’s dead serious, and you nod, speechless. A hand gropes your ass and you mewl, clutching at the bench as your thighs squeeze together.

“Be honest.”

“I-I will,” you manage to say, closing your eyes when you feel a finger brush against your folds as he moves the bikini to the side. There’s something even more thrilling about being exposed with the bikini shoved to the side, rather than taking off your bottoms at all, and it makes you warm all over. You gasp suddenly when his cock nudges your sopping cunt, and you bite back a moan as he pushes in.

You inhale sharply—despite prepping with his fingers, it’s still big—both length and girth. He goes slow, watching your reaction carefully like a hawk as he pushes in. He stills.

“Are you ok? Breathe for me, darling.”

You let out the breath you were holding, but you can’t help but clench tighter around Issei, making him grunt at the sudden movement.

“Fuck, you’re so tight for me,” he says into your shoulder, breath ghosting over your back. “Loosen up for me. I’ll make you feel good, promise.”

His hand wanders up to your chest, cupping at your breast before he toys with your nipple, gently flicking at it with his finger and relishing in the way your back arches and your meaning loudly for him once more.

With a few more pauses and sweet nothings whispered in your ear, you feel Issei’s hips flush against your ass, and the thought of his cock filling you up as you dizzy with lust.

“You feel that?” Matsukawa whispers. “Look at you.”

You bite your lip to stifle a moan and you turn your head to look at the mirror. His hips are right up against your ass, and your reflection looks absolutely wrecked as she stares back at you, stars in her eyes and little gasps escaping her swollen pink lips. Matsukawa, on the other hand, is absolutely glowing, the light on his sweat sheened skin making his muscles ripple as he holds your hips with his large hands, his hair falling against his face as he stares down at you with a heavy lust filled gaze.

You clench again, and he groans.

“Gonna…Gonna break,” you stutter out, half delirious by the sensation of his cock stretching you impossibly wide.

“It’s ok if you do, I’ll take care of you,” Matsukawa murmurs, eyes glued where he and you are connected. The hand on your ass squeezes, and you feel his thumb circling your opening, as if admiring the way he’s stretching you, intoxicated by your body and all of its sweet reactions to his touch. He moves, sliding in and out of you slowly, observing you for any indication of pain. When you do gasp, he stills immediately, asking if you’re ok before he continues his slow pace.

“I don’t think I’ll last that long when your cunt is squeezing me so tightly,” Matsukawa breathes out. “Fuck, if I knew you’d take me so well I would’ve done this back in high school.”

It hits a chord in you, and he grunts again when you clench with a gasp.

“Did you want this too, princess?”

“Y-Yes, always wanted you…it’s so much bigger than I imagined—” your voice breaks into a gasp when Mattsun twitches inside you. His palm is splayed out across your back where it arches, clenching uncontrollably around his thick cock.

“Imagined? I’ll make sure to go beyond your imagination, then.”

It’s the only warning he gives you before he starts moving his hips, rutting into you in punctuated movements. With each thrust, you feel yourself pushed forwards, your body going numb with pleasure as he hits all the spots that drive you insane. Warmth coils at your gut, tight and building as he drives his cock deep inside of you—your skin tingles with excitement. Suddenly—

“N-No Issei, don’t!” Your cries drown out the rest of your protests, and Issei grins against your shoulder, pressing harder against your stomach, right below your bellybutton where he can feel the tip of his cock drive into you. His other hand cups your tits, squeezing and fondling them before he slips under your bikini top, pushing it to the side to find your nipples easily, flicking and twisting them between his fingers.

Fuck, fuck—fuck your cunt is so tight around him and your wanton moans are for his ears only. He wasn’t lying earlier—even he’s impressed with how long he’s been able to hold back, but he feels the telltale signs of his orgasm approaching, the warmth burning tenfold when he sees how absolutely undone you are by his own hands.

“Say my name, baby,” he gasps, your given name falling from his lips. His fingers draw frantic circles around your clit. “Tell me who’s gonna fill you up.”

“I-Issei!” you cry, voice stuttering into a long keen. You’re absolutely gone, blissed out and desperate to reach your climax. “Issei, gonna cum—gonna—!”

He cuts you off by slamming himself deep into you, driven over the edge by the moan of his given name and nearly tipping you over as he pulls your hips closer to him. You have no doubt his cum is filling your cervix as he pulses inside of you, and you're shuddering around his cock, riding out your own orgasm as he presses his thumb against your clit. Ecstasy is all you feel, your limbs gone numb as Issei holds you up, squeezing your hips as he stills, making sure you’ve taken every drop of him.

With a shaky exhale, Issei pulls out, hissing at the feeling and instantly eyeing the way your pussy convulses before his cum leaks out of you in fat drops, painting your cunt and clit white before it falls onto the floor.

“Look at how messy you are,” Issei tuts, crouching down and lifting your chin so you can meet his gaze through blurry eyes. “Hey, stay with me. We have a lot to catch up on, and we’ll start by cleaning you up first.”

When he lays you down on the bench so your upper half is against the wood and your legs are spread out for him, you vaguely wonder if you should let the rest of your team know that you’ll be late for dinner.

All thoughts are thrown out the door as he takes his place in between your legs, spreading your thighs open as the first swipe of his tongue licks up the mix of your cum and his.
