Category: Angst, Smut

Warnings: Cheating, cursing, sex, some choking, slapping and mentions of violence (reader basically asks to be hurt), daddy kink (not ddlg), scummy Oikawa being an asshole, kind of toxic Iwaizumi, uh, that’s about it? Dm me if I missed anything.

Summary: Having your heart broken by Oikawa Tooru is unexpectedly hard, but it’s even harder to let yourself fall for someone new.

Songs that inspired this: “Sparks” by Coldplay, “Song for a guilty sadist” by Crywank and “Skinny love” by Bon Iver

Huge thanks to @velvet-kissesss for editing this and always being the first to read my stories! <3

Oikawa Tooru is like the sun. His smile is as bright as a summer day, his gaze as cold as ice, but he‘s still your sun. Or he used to be. Clouds of doubt that came in the form of suspicious text messages and excuses clouded his brightness and warmth that never really cleared away.

He‘s busy busy busy. You‘re always wasting his time, you‘re always annoying him with your silly messages, asking- no, begging for his time; which you know you won‘t get. Your eyes and heart are completely filled with Tooru, your sun.

Even his friends notice the odd behaviour of their former captain yet they mask their concerns for your wellbeing with jokes and laughs once you stop showing up to their weekly dinners.

The storm started when you overheard the conversation you weren‘t supposed to hear. It‘s a rare occasion to be home at the same time as Tooru, even in your shared apartment, your boyfriend so kindly paid for (You offered to pay rent, but even if he would‘ve accepted your offer, a broke college student would never be able to afford it). His voice sounded slightly annoyed, the notes barely there, but from the time you spent together you could clearly tell he was having an argument.

“I’m not fooling around. I don’t know what to do,”

You couldn’t tell what the argument was about, but you pressed yourself against the living room wall that divided the two rooms. Eavesdropping wasn’t good, but you were worried for Tooru. He was never home, never shared his worries and now he was getting into arguments. Your anxiety was rising. What if something was going on?

“I’m not leading her on, you don’t know what you’re talking about! The only girl you’ve ever dated left you before college started. Adult relationships are so much harder,”

There was only silence for a moment that seemed to stretch out into infinity.

“I’m thinking about ending things. I think… I’m almost sure I’m falling out of love with her,”

Everything went silent until then the ringing in your ears took everything away. Your head was spinning, eyes unable to focus on anything, lungs suddenly filled with water and throat with sand. Empty. Empty, so painfully empty but full at the same time. You were the ‘her’ of the conversation. You were the girl Tooru was falling out of love with.

You didn’t feel yourself falling onto your knees. You didn’t hear the loud thud, you didn’t even notice how cold the floor was until your silent bubble was popped by Tooru’s voice.

“Shit, Y/N!”

His arm on your shoulder felt so heavy. Too heavy, the water filling your lungs seemed to spill out of your eyes, tears running down your face. Oikawa kneeled before you, pulling you into him, letting you bury your face into his sweatshirt that used to smell like your perfume but now smelled of something unfamiliar and unwelcoming, his hand in your hair stung colder than ice.

He lets you cry, lets you grip him so hard, as if you think that letting go would be deadly and lets you whisper quiet “You don’t love me’s” until your throat becomes sore.

“You heard everything,” it wasn’t a question, rather a statement. His hand reached your back, rubbing in gentle circles but it was anything but calming. You felt as if you couldn’t let go because as soon as you did, Tooru would disappear. Your sun would never shine anymore.

“Don’t leave me, Tooru. Don’t leave me, please.”

His eyes watch your form, so defeated in his arms.

“I won’t.”

You’ve been together for such a long time, you’ve been there through the highs and lows, always cheering him on, always there to greet him with a smile after a long, stressful day, always so willing to do anything to make him feel better even if your late night love-making ended in being unable to walk the next day and having to conceal the finger-shaped bruises left on your frail neck. Maybe it’s the stress of trying to balance college and volleyball. Maybe it’s the way seeing your face and feeling your gentle touch doesn’t put a smile on his face anymore.

You at least deserve another chance. Another chance before he’s sure he fell out of love, even if he knows he has.

“Y/N, I won’t leave you, I won’t,” he repeats like a mantra, like he wants his words to fill you full, like he wants you to believe it; even if he himself won’t.

You don’t remember being carried to the bed, you don’t remember Tooru covering you in a soft, fluffy blanket but he’s still there when you wake up, with your back pressed against his chest, his long arms draped over you and his head resting against your shoulder.

It's idle, it’s painfully normal that you can almost pretend nothing bad ever happened, that he still loves you the same way he did before. You can almost feel the brightness and warmth of the sun after being lost in the dark for so long.

The next few weeks go by fast and Oikawa keeps his promise. You never feel lonely, constant fancy dates that feel foreign after such a long time and the awkward smiles of his friends when he starts bringing you with him again.

It almost feels too good to be true. And it is, as you learn when you return from your shitty part-time job earlier than usual.

Don’t fly too close to the sun or you will burn. And you were burnt. Like Icarus, the wax of your wings melted and your false feelings of security you held onto are shattered into tiny pieces, never to be collected by anyone.

He’s in the arms of another woman, another pair of lips is kissing away at his skin, tainting him, the sight making you dizzy when you can’t take your eyes off of their tangled bodies.

The woman notices you first, yelping and pulling the covers to save any dignity she has left. Oikawa can’t look up. He’s physically sick, any minute and he’ll throw up. Is he mad because you showed up early or is he disgusted by himself? The feelings mix into a dangerous combination and he’s unable to say anything.

Only when you open your mouth do the apologies begin pouring out of his mouth, the girl beside him long forgotten as he climbs out of bed, pulls his sweatpants on and chases you into your shared bedroom.

He catches your wrist and tries to tug you closer when you reach for anything you can. Your charger, a few clothing items and your favorite perfume he gifted you, tossed carelessly into a bag and all that’s left is the sorrow in your eyes.

He wants- no, he needs you to be mad, but as tears flow down his face he can’t help but shout at you, grab you by your shoulders and violently shake you until you plead to him to let you go, until there’s fear mixing in with the tears in your eyes.

After he releases his iron grip, you storm off. All there’s left is the bruises starting to bloom on your skin and the voice of another woman.

Oikawa throws up soon after that.

***

Your phone is overwhelmed with notifications from missed calls and messages, but you run until your legs are sore and your lungs are burning. The bag in your hand is the only thing still grounding you to this world while your tears mix with the pouring rain as you fall on the cold, slimy sidewalk once again; your tights ripped and dirty.

You reach for the door already shaking and even more pathetic-looking than before. The doorbell rings a silly melody and you consider walking away before you make a fool out of yourself, but you don’t have the time to re-think that decision when the door swings open, a slightly annoyed looking Iwaizumi standing before you.

His scowl drops as soon as he sees it’s you and his features form a worried expression when he takes in the state that you’re in.

“Y/N, what- What the fuck happened?” he doesn’t wait for your answer, already ushering you inside as the warmth of his home seeps into your tired, frozen body.

“I-“

He guides you to the living room immediately before turning up the heat and sitting you down on a couch, before sitting beside you.

You don’t dare look at him.

“Y/N, tell me what happened.”

He’s worried and you shrink into yourself, the feeling of guilt unbearable. You’re not worth the worry.

“Oikawa he…I found him having sex with another woman.”

The words come out fast, like ripping off a band-aid. Iwaizumi frowns, his lips part in disbelief. Oikawa told him he was falling out of love with you, but… cheating on you in your own home was a whole ‘nother thing.

Iwaizumi didn’t know if his face showed any obvious disgust or anger, but your hands started shaking.

“Should I go?” your eyes find his, fluttering shut to hide the glossiness, “Iwaizumi, tell me if you need me to go. I know that Oikawa is your friend and that I’m just some girl he dated but I didn’t know where else to go, I didn’t know who else to call,”

He can feel your uncertainty and stress so he does the first thing that comes to his mind; gently grabs your hands, flinching when he finds them ice-cold.

“First of all, you’re not just some girl, I have known you since our third year of high school. I’m your friend as much as I’m Oikawa’s. And I won’t let you go anywhere, not in the state you’re in.”

You stare at him in disbelief, hands still shaking.

“Yeah, Iwa, we’re besties for life,“ your voice breaks as you try to make a joke.

You can’t help but burst into tears again. Pathetic, fucking pathetic and annoying. Your thoughts run wild, trying to find a reason why Tooru did this to you.

Iwaizumi pulls you into a tight hug while you’re left with your arms awkwardly hanging limp by your sides, your tears and snot soiling his shirt.

“Listen, you’re cold and your clothes are wet. How about you go take a shower while I make you something to eat? Then we can talk more about it, if you want to. But you will catch a cold staying in those wet clothes.”

The kindness is unexpected. You knew that the dark-haired man never lacked compassion, but he was so painfully kind. Too kind.

“Iwaizumi- It’s too much. I-“

He doesn’t let you finish, already letting you go to bring you a set of fluffy, fresh towels.

“It’s what any friend would do. Please listen to me, I don’t want you to get sick. Please.”

There’s too much “please’s” in that sentence, but you do as he asks and let him guide you into the bathroom, pretending to listen when he tells you something about using any shampoo and shower gel you want.

And then he leaves you alone. Painfully alone again.

You undress, the wet clothes falling to the floor. Your biceps have handprints imprinted on them and you can’t stand to look at yourself anymore as you climb into the huge bathtub.

The water is boiling and it feels like your skin is going to peel off as you trace patterns on your tired body, trying to burn Tooru’s touch away; but no water could ever be hotter than the sun.

You don’t know how you find the strength to wash your hair, but the musky, citrusy smell of Iwaizumi’s shampoo untangles the knots in your hair, keeping your head empty. Or, as empty as it can be.

You don’t know how much time goes by but you’re sitting down with your back against the shower wall when a knock comes.

“Y/N? I don’t want to bother you and you can take your time, but I went through your bag- I- I uh wanted to find you some clothes, didn’t mean to snoop around. But- Uh, but you don’t have any warmer clothes packed so I brought you some of mine. I’ll leave them by the door.”

There’s no footsteps and you realize he’s waiting for an answer. Is he worried? Afraid you’ll drown yourself in his shower? A soft laugh slips past your lips.

“Okay.” your voice sounds like it doesn’t belong to you; too distant and unrecognizable.

The footsteps fade away and you decide to not feed into Iwa’s fears as you step out of the shower, drying yourself off.

Wrapped in a towel, you open the door and grab the pile of clothes Iwa has left. There’s a pair of panties and a bra from your bag, then a pair of sweatpants and a huge hoodie you don’t recognize so they must be Iwaizumi’s.

Getting dressed feels like a chore. Your arms are heavy and your legs feel like they’re made out of wood. Iwaizumi’s clothes smell just like him, musky and citrusy, erasing the smell of sex that haunted you since you stormed out of your home.

The clothes fit you weirdly but you can’t complain, because they’re warm and comforting.

An aroma coming from the kitchen almost makes you dizzy again and you realize that you haven’t eaten today.

“Sit down,” suggests Iwaizumi, as soon as you step into the kitchen, “I made ramen. It’s not anything fancy, but I didn’t do any grocery shopping recently. We, uh, I could order you take-out if you’d like that more?”

You hop onto one of the comfortable chairs and muster a smile.

“Iwa, it’s fine, ramen is fine.”

That seems to calm his concerns, even if for a little bit. You eat in silence. He seems to observe you, blushing as soon as you catch his glance, but you don’t have the energy to ask him anything.

You want to help him wash the dishes, the guilt of him being so kind and you not being able to do anything in return, but he just asks you to sit down, assuring that he’s got this.

He stands before you after putting the dishes away and once again grabs your hands. You don’t know if it’s to comfort you or because he doesn’t know what to do, but his hands are cold and unfamiliar; though his touch isn’t unpleasant or unwelcome.

“Do you want to talk about it?”

You manage to shake your head, letting it fall into his chest. The position is awkward, but one of his hands almost automatically begins massaging your back in slow motions.

“Ok, we will not then. Makki- uh, Makki said that you liked watching ‘Howl’s moving castle’?”

You lift your eyes, raising an eyebrow at the brunette’s statement.

“Makki remembers stuff like that?”

Iwa lets out a dry laugh, as if trying to lighten the atmosphere.

“He said you made him watch it with you twice.”

A ghost of a smile graces your lips.

“No one else would, so Makki was my only option. It’s not like he didn’t enjoy it. I even heard him talking to Mattsun about it.”

It seems like your mind wanders off for a second. ‘Good’, Iwa thinks.

“Do you want to watch it right now? I can bring you a blanket and like, snacks or something? Or you can go to sleep if you’re tired, I already made the bed.”

You’re lost in your thoughts for a moment and then your gaze meets the former vice-captain’s olive eyes again.

“Can we um, can we actually watch ‘Jurassic park’ instead?” you ask, uncertain.

“Yeah, of course we can,”

A good hour passes and you’re halfway into the movie, hidden almost completely under the warm blanket, when Iwaizumi turns his face away from the TV to focus it on you. His slightly chapped lips part, as if he couldn’t voice his thoughts.

“Everything okay?” you ask, turning your attention away from the blood-thirsty dinosaurs chasing a group of people.

“Why did you pick this movie?”

You feel heat flood your cheeks, palming the material of the blanket.

“It’s one of Tooru’s favorites. He likes watching dumb dinosaurs and even dumber people.”

Your answer is quiet, but Iwaizumi knew the answer even before the words left your mouth, he only needed you to confirm it. How does watching a movie that the ‘person who cheated on you’ liked could bring you comfort?

“I know it’s stupid and God, um, I probably look pathetic right now and all but,” you pause to take a deep breath, tears threatening to spill all over again, “If I watch it closely enough, I can almost convince myself that everything’s like before. That we’re watching a movie with you and Tooru and he just left to get a drink.”

Soft cries that you fail to silence leave your lips as Iwaizumi pulls you closer, not resisting enough to look at you so hurt and defeated. It’s probably weird to hug you as much as he did today, but you don’t seem to mind, burying your head into his shoulder and crying away. He’s not good with words; the complete opposite of Oikawa, who makes small talk and comforting words look effortless. Physical comfort is his only way Iwauzumi can show that he truly cares.

It’s a good half an hour before you’re asleep in his arms, the movie long-forgotten. Iwaizumi’s eyes take in your form. You poor thing, Iwa didn’t really know how to help you or take your pain away besides taking care of you the best he could.

He reaches for his phone on the edge of the sofa, wanting to check the time and probably carry you to the bed but he finds tons of notifications still ongoing. They’re all either from Oikawa or the groupchat of the former third years.

He doesn’t bother responding to Oikawa, opting to read the groupchat. He can’t care enough to read all the messages they’ve exchanged while he was gone so he scrolls a good bit.

Shittykawa: fuck, you really don’t know where she is?

Makki: for the 10th time, we tried calling her friends.

Makki: none of them know, how do you expect us to know?

Shittykawa: just fuck

Shittykawa: shit, this is so bad. What if something bad happened to her?

Mattsun: Yeah? Something like her boyfriend cheating on her?

Mattsun: Oh wait :D

Makki: mattsun, now’s not the time

Makki: oikawa you fucked up and I want to personally beat you up, but blowing up the groupchat won’t help you find Y/N

Makki: take a breather, calm down. I’m sure she just went to some friend we don’t know or something

Shittykawa: I’ll try calling her

Iwaizumi scowls, fingers typing out a fast response.

Iwa-chan!!: don’t

Matssun: Iwa? Wtf

Iwa-chan!!: she’s at my place

Iwa-chan!!: she’s safe and asleep, just finished crying her eyes out

Shittykawa: what the actual fuck

Shittykawa: I’ve been calling fucking everyone and NOW you decide to tell me she’s at yours?

Makki: why is she at yours tho?

Mattsun: Yeah, would’ve guessed she went to Mina’s or smth

Iwa-chan!!: well im her friend too so

Makki: yeah, it’s just weird

Mattsun: She also could’ve went to ours lol

Makki: good thing she’s at Iwa’s

Makki: I couldn’t handle another marathon of fucking studio Ghibli movies

Mattsun: Where’s Oikawa tho?

Shittykawa: omw to Iwa’s

Iwa-chan!!: wtf no

Shittykawa: I’m taking her home

Mattsun: Yeah, probably not the best idea

Iwa-chan!!: she just fucking cried because of you, you think she wants to see you

Makki: you should give Y/N space, Oikawa

Makki: I doubt she wants to see you rn

Shittykawa: don’t care

Shittykawa: open the door Iwa

Iwa grunted, gently moving you away from his shoulder and slightly increasing the sound of the movie, not wanting to wake you up when the inevitable screaming match between him and Oikawa breaks out.

Makki: wanna bet ¥1000 that Iwa at least slaps Oikawa?

Mattsun: Nah, I bet ¥2000 that they get into a screaming match and wake Y/N up

Iwa puts his phone down, not bothering to read any more incoming messages and moving to open his door. He doesn’t want to. Doesn’t want to look his best friend of so many years into eyes. Doesn’t dare wonder what will happen when you wake up and see Oikawa here.

Despite so many reasons to not open his door, his arm automatically reaches for the handle and swings it open.

Oikawa stands there, looking like a ghost in the pale moonlight. His features seem blurry in the light, warm brown eyes now cold as ice. He pushes past Iwa, uninvited and slams the door shut, eyes searching for any sign of you, as if you’re just going to appear out of nowhere. One of Iwa’s hands clutches Oikawa’s shirt sleeve and holds it tight.

“She’s sleeping, don’t you dare go and fucking wake her up after the day she’s had,” grunts Iwa, dragging his best friend to the kitchen. Despite being there so many times before, today Oikawa seems out of place.

“I’m taking her home,” states Oikawa, once again.

“No, you’re not,” retorts the dark-haired man, “Sit the fuck down and let’s talk.”

Oikawa begrudgingly pulls out a chair and sits down. They’re looking at each other for a moment, not daring to break the silence. It almost feels like everything is okay, for a moment, like nothing happened, like it’s another quiet evening spent talking at Iwa’s house. If Oikawa concentrates hard enough he can almost imagine hearing your’s and Makki’s banter over the movie choice for tonight and Mattsun chuckling. Almost.

“What the hell were you thinking? I thought everything was going okay,” Iwa tries to ask calmly, but the way he talks through his gritted teeth alarms Oikawa that they’re not about to have a quiet, calm conversation.

“I wasn’t thinking. Y/N wasn’t meant to walk in.”

“So you planned to cheat on her and just go on with your life, God I-“ Iwa stops to take a deep breath. He knows he needs to keep himself level-headed but it’s so fucking hard, “When you told me that you’re falling out of love I was hoping everything would turn out okay. Even if not, I thought you’ll just break up with her, not… Not that,”

Oikawa looks lost. His eyes trace the coffee mugs on the table, then reach the colorful rag near the sink and then travel back to Iwaizumi. Hajime knows that his friend is looking just above his eyes, avoiding the judgemental gaze.

“What am I supposed to do now?” the former captain’s voice is merely a whisper, the confidence it always carries gone.

Iwa sees the way Oikawa is suffering, yet he cannot find it in himself to feel sorry for the former captain. The complete and utter selfishness of his actions; disgusting.

“Get out and sleep it off. Let her rest, that’s the best you can do.”

“I want to see her, to apologise, to-“

“Would you want to hear apologies from your partner, who you just caught cheating on you?” Oikawa’s face drops even more, if possible. A frown takes its place on his guilt-ridden features, a bunch of different thoughts making it hard to focus.

“I fucked up- I,” Oikawa’s searching for words, but can’t seem to find any, “There’s no coming back from this, is there?”

Iwa looks up. Seeing Oikawa in so much pain almost makes him physically ill. He feels conflicted. He wants to comfort his best friend, tell him that everything will be okay, that this situation has a solution, but Iwaizumi has never been a good liar. The former vice-captain manages to nod and they sit in silence until there’s footsteps.

Oikawa scrambles to stand up, already at the kitchen entrance before Hajime manages to catch him. It’s like their conversation flies out of Oikawa’s head — he’s trapping you in a tight hug, whispering promises and apologies, while you just helplessly stare at Iwa.

“Let me go, Oikawa,” you mutter, voice completely powerless and void of any emotion. The usage of his surname sends a shiver down Tooru’s spine. Small details begin to fall into place – your red, puffy eyes, the way you hold yourself like you just want to hide and the fact that you’re wearing his best friend’s clothes. You smell like Iwaizumi and that finally snaps Oikawa out of his trance. He lets you go, “If you have any respect left for me and my feelings, please leave”.

You say the sentence with such exhaustion that it seems like it’s physically hard for you to speak.

“I’m gonna leave, alright?” He leans a bit, so that you can look straight into his eyes. It seems like he has been crying too. You catch Iwaizumi’s gaze in your peripheral vision, “But please know that I’ll be waiting for you to come back, okay?

Your eyes wander away and he abruptly grabs your shoulders. You notice Iwa tensing up.

“I know you’re too smart to listen to my apologies, but please consider it, okay? I know you love me, Y/N, so think about it. I’ll come pick you up anytime, alright?”

You manage a nod and just like that – Oikawa is gone, a quick goodbye to Iwaizumi and he’s out the door. It hurts, hurts so fucking much. A moment of enlightenment then complete darkness again.

“Y/N…” Iwa is careful when he hugs you, like he’s afraid to hurt you. You step away so that you can look into his eyes. Dark green mixed with olive and brown tones seems to magically reel you in. You just want the pain to go away, even if for a moment. You’re so incredibly close to him and you can’t resist – your lips connect and you close your eyes. Iwaizumi doesn’t seem shocked, and even if he is, he instantly kisses you back.

His lips are slightly chapped and his hands explore your body carefully – every move and touch thought through.

He pulls away for a moment and your arms instantly reach to pull him closer, to go back to the state with no thoughts and problems – just pure passion, kisses filled with sadness and longing.

“Do you really want this?” he murmurs, almost into your lips, “Do you really want me or am I just a temporary replacement you can imagine Oikawa’s face on?”

He can read people so well, even if it doesn’t seem so. There’s nothing else besides physical affection and a long-lasting friendship. You trust him, you trust him to take the pain away, to make you forget your sun.

“I want you to take the pain away,” you answer him and your lips meet once again, “Please, Ha-ji-me,” you say his name in between kisses and Iwaizumi curses himself.

He’s an awful person and an even worse friend – leading, no, dragging you into his icy cold bed, when he should be comforting you, kissing away at your neck and quickly undressing you instead of calling Oikawa to come up with a way to fix this mess. He can’t help it, he can’t help himself from marking your pretty tits up when he’s wanted you since third year in high school, since you were utterly and completely Oikawa’s.

Having something so forbidden is exciting and Iwa knows that he can still back out, can still stay a good friend to Tooru, but why not just give him a taste of his own medicine? God, his moral compass is all fucked up.

His fingers softly massage your clit until they dip lower, slowly and softly fingering you while his thumb plays with your clit. He swallows up your sweet moans and mewls within his mouth, kissing you roughly and full of passion.

“Good girl,” he mutters, leaving yet another mark on your neck, the possessive side of him enjoying the already visible bruises that litter your upper body.

You whine when he thrusts particularly hard, hitting the spot that almost makes you instantly cream around his fingers.

“D-don’t be gentle, okay? I’m not gonna break,” you manage to say in between moans, “I want you to cause me physical pain, yeah? O-oh- so t-that I can forget why It’s hurting so much,”

Iwa’s brain seems empty. On one hand, he should be comforting you, not hurting you, but on the other hand, how can he say no when you look up at him, utter and complete sadness clouding your teary eyes, short pants slipping past your plush lips.

“You want me to make it hurt?” he chuckles, one huge hand enclosing around your neck with the other still inside you, grinning when you lean into his cold hand’s touch, desperate to be ruined, “Okay, I’ll do that.”

Iwa’s not a sadist in bed, most of the time, but you asked him to make you forget. And to be honest, he really wants you to forget. How euphoric would it be if that fucked-out look would be reserved for him only?

“A-ah, can I come, please?” you ask, hardly able to talk, pupils dilating, hands trembling and reaching to grab his snow-white sheets, looking for something to hold onto.

“Good girl, such a good girl asking for permission,” he mumbles and your eyes light up, but then the hand on your neck squeezes harder and you’re left with your mouth agape, watching Iwaizumi’s delighted face as he fingers you into completion, “You have to ask nicely if you want to cum. What did you used to call Oikawa?

His fingers slow to an agonizing pace and you let out a groan in frustration. Iwa wonders if he’s crossed a line with his questions, but all his worries are calmed down, when your eyes sparkle with fresh tears and you manage to sob out a frantic “Please, daddy, please, can I cum?” as if you’re afraid the brunette will take away your pleasure.

“Cum” he orders, high on the power you basically handed to him without any resistance. And then he watches you come undone on his fingers, your face filled with ecstasy as you keen and cream around his fingers.

Iwaizumi gives you a moment to get yourself together and breathe as he moves his hand away, but after that he’s expectantly shoving his fingers with your juices towards your face and beams when you suck his fingers clean; even without him asking.

He strokes your cheek and pulls out his pulsing cock out of his boxers. He’s so impossibly hard and he just can’t wait to be in you, feeling the heat of your tight walls on his dick.

You look down and your eyes become as wide as saucers – he’s no longer than Oikawa, but definitely thicker, oh you just know you’ll have trouble walking the next day.

“Don’t worry your pretty little head, baby,” he chuckled, “Let daddy take care of you.”

There’s thoughts rattling through your head for a moment, but then you give in and nod – still not able to completely think after a mind-numbing orgasm.

Iwaizumi lines himself up with your creaming hole and then pushes in. You mewl and keen, but he keeps going, swallowing all the noises with comforting kisses, knowing that If you’d really wanted him to stop, you would’ve told him so. Inch after inch and he’s finally bottomed out – your pelvises rubbing together.

“I’m gonna move now, yeah? Pretty girl,” he can’t help but praise you – so pretty, all submissive and blissed-out just for him.

Iwaizumi’s thrusts are hard and fast – it seems like he wants to engrave the shape of his cock into your tight walls and his name into your fuzzy, pleasure-filled brain.

“Daddy-“ you whine, “So good, feels mmhm- feels so goo-good!” you scream, biting at his neck, making the brunette suck in a harsh breath.

“Yeah? You’re gonna be my good girl after this, huh?”

You can’t focus your thoughts to answer – the feeling of his cock dragging against your walls, the way his muscles are flexing when he grabs your hips, the way he smells, the-

Iwaizumi slaps you. Not hard, but hard enough to get your attention and for pain to begin blooming in your cheek.

“Daddy asked you a question. I expect you to answer, honey.” His green eyes are darkened with lust, pet name condescending.

“Y-yeah, gonna be your good girl, daddy,” you pant, breath coming out in short puffs.

From your expression and the way you’re clenching down on him, he can feel that you’re close.

“You on birth control?” Iwa asks, not completely lost in pleasure, still able to think, but fuck is the thought of coming in you hot.

“Y-yeah,” you cry out, “Cum inside me, yo-you can cum inside me,”

That’s all it takes. His vision flashes, strong arms trembling and squeezing your hips even harder and then he paints your walls white. You come soon after – a little stimulation to the clit and you’re coming on his softening dick.

You stay there for a few moments, both breathing and collecting yourselves. Iwa falls to your side, pulling you close to him, tucking your head under his chin, your hot breath tickling his neck.

“Thanks,” you manage to say, before blacking out. It seems like today’s events really tired you out. Hajime doesn’t mind. He could get used to this. Used to you in his bed, used to you being completely his. He couldn’t get used to the guilt though. He stays up, lost in thought, until first rays of liquid gold begin leaking through the curtains.

Iwaizumi picks up your things from your’s and Oikawa’s place. You’re miserable yet again – asking Iwaizumi to do it for you through hiccupping sobs.

His best friend of many years has your bags ready, your shared apartment weirdly empty, cold and unwelcoming without your things.

“So she’s really not coming back,” Oikawa mutters. He looks even more miserable than you; it’s fucking depressing and the guilt comes back stronger than ever. Fuck.

“Well you can’t blame Y/N. You cheated,” Iwa retorts, tone colder and harsher than he intended.

“Yeah, that,” Tooru laughs, a noise so empty and pathetic that his best friend cringes, “Does she have a place to stay?”

“She’s staying at mine’s”

“You’re fucking, aren’t you?” Oikawa chuckled and Iwaizumi froze, “Figured. I have no reason to be mad at you, Iwa, but I fucking am. Still feels like… She’s mine, you know? And I really wanna fucking beat you up for touching what’s mine, but I’m not going to do that,”

Iwa nods. His best friend was always too good at reading people. Too good for his own good.

“I’m going to Argentina soon. Got a good deal to play at in professional team while still being able to finish my studies,”

“That’s… That’s amazing Tooru,” Iwaizumi is excited for him – there were no doubts that he was going to make his dreams come true, but it’s like a weight has lifted off of Iwa’s shoulders; Oikawa is going to be miles away from you and you’re not going to fall back into the setter’s awaiting arms.

“I know you’ll feel like she’s completely yours when I’m gone, but I’m not doing this for you. I want to change, to be a better person. A new country might help. But I won’t be gone from her life, yeah? I’m still her friend, even if it's a really shitty one. Time heals people, who knows what the future will bring.” Oikawa smiles and Iwaizumi’s heart beats in his chest.

“If you want to get back with her someday- I won’t- I won’t let you. Okay? Yeah, you have everything and she’s mine. You had your chance, Tooru,” Iwa is about to walk out, your bags in his hands, but there’s something stopping him. Right, “Text me when you’re there, tell me how you’re doing. Still want to know that you’re safe.”

“Will do,” Oikawa responds and the door to his apartment closes. It’s over.

Iwaizumi blocks Oikawa’s number from calling you. The less you know the better. He’s away now and he doesn’t have time to call you. Everything is over and you’re happy with Iwaizumi.

But when you press his hand against your neck harder and harder, the look in your eyes looks something close to a prayer, begging. He doesn‘t know if he should cry for himself or for you, because you‘re asking him to hurt you over and over again, harder and harder, for the physical pain to replace the everlasting ache in your heart; if even for a moment. You are completely and utterly Oikawa Tooru‘s and no matter how many “I love you’s” you whisper into Iwaizumi’s neck on lonely and self-hatred filled nights, when the sun is replaced by the moon, he knows that you’ll never be his. That he’s never going to be your sun. He knows from the way your hands reach for your phone as soon as it rings, from the way your face drops when it’s not the voice you crave to hear, from seeing your eyes tear up when you’re looking at him, your head spinning from trying to imagine a different face instead of Iwaizumi’s.

It's stupidly foolish of him to hope that he could ever be enough for you. That he could ever replace Oikawa, replace the man you compared to the sun. Iwaizumi was cold and bitter, the care and worry always masked by a scowl. Could he be your moon at least? Would you ever be satisfied with the coldness of the moon, when you once had the warmth of the sun?

Iwaizumi doesn’t want you to answer the questions he never voices, the ones you have probably already answered hundreds of times in your head.

All he can do is pull you closer and hope to be enough. The night is filled with sounds from the city that flow through the open window alongside the darkness. He can almost pretend he doesn’t feel the uneven rise of your chest, almost ignore the quiet sobs you try to hold in.

Iwaizumi buries his face into your hair, the citrusy and musky smell of his shampoo filling his senses assuring him that he’s not in the wrong here.

So why does it feel so bad to be selfish for once? To hold you in his arms like this, seeking to give you the comfort he knows you crave from another.

Why does it feel so bad to keep you away from the sun?
