A/N: Chose the names for the kids completely random, also I was a horrible teenager and I still feel bad what my poor parents had to go through with me. Also, the Spanish translations are from my male best friend whose mother tongue is Spanish, I am sorry if it’s not correct, I’ll kick his ass if something is wrong 😂
TW: period blood
Tōru Oikawa is many things.
King of the court, former national Argentinian Setter, husband of a beautiful successful, confident woman he calls the love of his life and father of three children.
Now as a retired athlete, the former Setter trains all sorts of volleyball clubs in San Juan. From little kids trying out Volleyball for the first time to High Schoolers and even College students trying to go pro.
All these years, you raised the children mostly while your husband played volleyball professionally until he couldn’t do it anymore physically. With coming age, every athlete reaches their breaking point sometime.
Now working your dream job as a novel publisher about a romance novel you recently published, you’re in the United States, traveling and doing interviews about it.
The two of you always wanted a family.
After Tōru did the try outs and made it on Argentinian team, the the two of you celebrated with a lot of alcohol and passionate kisses and just like that, your first child was born 9 months later.
Just by the age of 22, Tōru is a father of a beautiful girl named Sofia, she was born in the bright early morning light in December.
As first time parents, there were ups and downs but you both pulled it through as a team.
During the years, you and Tōru brought two more lives into this world, one girl and one boy. Hikari and Thiago.
Sofia is now 13 years old, which means she is a teenager now. Hikari is 10, while Thiago, the youngest, is 7 years old.
Thiago does not always has it easy with two older sisters, especially since Sofia has had incredibly bad mood swings that she occasionally lets out on her siblings, causing fights to break out that the poor former retired pro Volleyball player has to break up lots of times.
Unfortunately the former Setter’s wife is out of the country for interviews and signing her books, leaving the man to run the household by himself.
During years of intensive training, raising three children, nothing could have prepared the brunette for this.
Puberty.
On Saturday morning, Tōru prepared breakfast for his kids when Sofia came out of her room with an annoyed expression.
No.
Pissed expression.
She sits down at the table without greeting her family and just begins to tear apart the waffles without eating them.
"What’s wrong with you?" Hikari asks in a curious voice.
"What’s wrong with your face." Sofia’s voice is full of venom, like her sister took away her iPod again without asking her first.
"Hey! Ya basta." Tōru scolds her with a frowned expression.
Sofia’s mean demeanor drops a little bit but the anger on her face still remains. She definitely inherited your angry expression that Tōru is still terrified of.
Thiago is just munching on his Lucky Charms cereal, ignoring his sisters’ antics like always.
While both daughters inherited your looks, Thiago looks like a solid copy of his father. The same hair, the same eyes, the same face.
When the Setter cleans up the mess from the cooking, an idea pops up in his head. Something he hasn’t done with his kids in quite a while due to their school activities and homework.
"Hey kids, how about we play some volleyball in the garden later on? We haven’t done that in a while." Tōru suggests.
The two younger Oikawas brighten up with excitement, whereas the oldest one barely reacts.
"Go got ready after breakfast, I'll clean everything up and Thiago, go get the volleyball in mum’s closet." Tōru tells his kids, a huge smile breaking out on his face when his youngest one quickly chows down the rest of his food before running upstairs to get dressed and fetch the volleyball out of his parents’ closet.
Hikari also finishes, setting her plate in the dish washer before going to her room as well, getting ready to play volleyball with her brother and her father.
Tōru looks at his daughter and she pushes her plate away, leaving the table without another word.
"Sofia, you know you can talk to me. Qué te preocupa?" The brunette calls out to her.
She doesn’t reply, just keeps on walking and closes the bathroom door with a slight slam.
With a deep sigh, Tōru finishes cleaning up, wishing his wife was here to help him figure his teenage daughter out.
All of sudden, he hears Hikari and Thiago running down the stairs, this time in sports attire instead of their pajamas.
Making a run for it, Hikari trips Thiago to be the first to arrive in the garden of the house.
With his face landing on the hardwood floor, he groans out loudly in pain before getting up and yelling after his sister.
Rubbing his temple in annoyance, Tōru makes his way to the bathroom to try and get his eldest daughter out to join the family fun.
Knocking gently on the door, the father begins to talk.
"Sofia? You okay?"
"Go away, dad!" She yells out behind the door and it sounds like she is scared but also deeply upset.
"Preciosa, what’s wrong? You okay?" He begins to get worried.
"It’s nothing, I just… I-I need mum for this." Sofia sounds embarrassed as she says it out loud.
Tōru pouts a little bit at that, his little girl choosing you over him.
"Maybe I can help you." The father offers.
"No! You can’t! Gosh, this is so embarrassing!" She shouts in reply.
Now Tōru is starting to freak out a little bit.
"Sofia, tell me what’s wrong or I will knock down this door, I am not kidding!"
No reply.
"There’s… there’s blood… in…my…" She stutters.
Pressing his ear against the door, he tries to listen what she is trying to say.
"Blood in your what?!" Tōru asks frantically.
Now both Oikawas are freaking out.
"I GOT MY PERIOD, YOU HAPPY?!" She finally snaps and yells.
It seems like time has stopped for Tōru Oikawa.
Why, why?!
Out of all the times, it happens now?! When you’re gone and he has to deal with it by himself?
'Deep breaths, Tōru. You can do this.'
"Nena, please open the door. I’ll try to help you in any way I can."
"You can’t! I read online that I need something called a pad or a tampon. Do we have any of that here?"
Tōru knows whenever you’re having your period, you keep your feminine products on top of the med cabinet, out of reach from prying eyes.
Hikari and Thiago return inside the house after a while, confused why their father hasn’t come outside to play yet.
"What’s going on with Sofia? Is she sick?" Thiago worriedly asks.
Hikari appears as well, more annoyed than worried like her little brother.
"Sofia, if you die, can I have your laptop?" She teases.
"No! When I get out of here, you’re done for, you little shrimp!" Sofia snaps back.
"Oy! No one is killing anyone! I will be right there, just leave your pa and your sister for a bit okay? I promise I will be there."
Tōru interferes, before Thiago becomes an only child, more likely foster child, since his wife will kill him as well.
Hikari and Thiago make their way outside again, with Thiago jumping on his sister’s back like a warhorse.
They both scream as they head outside again, while Tōru only shakes his head at their silliness.
"Mijita, check the top of the med cabinet."
"What? Why?" Sofia asks perplexed.
"You’ll find what you’re searching for."
After a few minutes of rustling and hearing movement, the father hears the rustling of plastic and the uncertainty in his daughter’s voice as she describes the products.
"You found everything?"
"Yes, thank you, pa…"
"De nada, linda. I’ll explain from the door how to use it."
Tōru does not move from the door, explains to his daughter step by step how to use the different kind of feminine hygiene products, also offering to buy her favorite candies and food tomorrow and even if Tōru can’t see it, Sofia has tears in her eyes, appreciating her father’s supportive nature so much.
When you return from your trip, Tōru is watching a volleyball game between England and France, eyes captivated by the screen.
He is sipping on a beer can, eyes on the tv, switching between cursing and cheering for the teams.
Entering through the entrance door, you spot the love of your life immediately.
"I haven’t seen you drink a beer since high school. Any special occasion?" You grin as you hug your husband from behind, your arms wrapped around his neck.
Pressing a chaste kiss against his temple, your brunette husband chuckles and intertwines one of your hands with his.
"Bienvenido de vuelta, ¿Cómo fue tu viaje?" Tōru asks while briefly looking at you over his shoulder.
"Amazing! The people are very nice and I was busy every single day. How was home?" You ask in return.
"Puro pánico y discusión entre hermanos." Your husband sighs while taking another sip of his beer.
"What do you mean?" You say in a very concerned voice, already bracing for the worst.
"Your daughter had a mental breakdown over her first period today."
"MY daughter?! She’s your daughter too, marido."
"ANYWAY, your amazing marido handled it, amore. They are all asleep, Sofia and I had a long and big talk, you don’t need to worry your pretty little head about anything else."
You smile brightly at him, remembering you have a little souvenir gift for him.
Quietly unzipping your suitcase, you change into the surprise you have for your husband.
"Tōru?" You quietly call out to him, leaning against the entry way of the living room, doing a sexy pose of the new black Victoria’s Secret lingerie you got from the States.
"Hm?" Looking over his shoulder once more, the brunette’s eyes almost pop out of their sockets, choking on the sip of beer he took, while taking your figure in.
"Ven y cógelo, mi capitán." You say in a seductive voice, walking towards the direction of your bed.
Jumping over the couch, the Setter follows you into your shared bedroom, full of excitement and horniness for his precious wife.

Warnings: suggestive content, mentions of sex
Having Oikawa as a temporary roommate doesn’t sound too bad at first.
Unless you’re dating his best friend, Hajime Iwaizumi.
Both you and Iwaizumi have been high school sweethearts, now dating officially for almost 8 years.
While your boyfriend, actually fiancé now, is working as an athletic trainer for the national Japanese volleyball team, you work as a pharmacist in the local hospital.
When Iwaizumi came home after a work-out one night, he had an annoyed expression on his face when he entered your apartment.
Pausing your actions on making dinner, you know that face already.
"What?"
Iwaizumi sighs, drops his gym bag and walks over to you with an exhausted expression.
"Those shitheads are really getting on my last nerves. Thought I lost them all already back in high school with Oikawa." The brunette hugs you from behind and can feel himself relax when he smells the familiar smell of your pineapple and coconut shampoo.
Which reminds you.
Oikawa texted you yesterday, asking if he can stay at your place for a week while he is training with his Argentinian team at the Ajinomoto National Training Center.
And the Setter knows the former Outside Hitter all too well, knowing 100% already that Iwaizumi would just leave him on read when he reads Oikawa’s message about staying at your guys’ place.
Which is why Oikawa asked you instead, knowing you’re Iwaizumi‘s kryptonite.
And Iwaizumi can never say no to you.
"Say love, don’t be mad at me."
The bliss on Iwaizumi’s face disappears and he turns you around to look at you with a frown on his face.
"What did you do?"
"Uhm… you know how much I love you? Your muscles certainly got a LOT bigger-" Tracing his firm pegs with your finger, you start to get distracted.
"Don’t try and sweet talk your way out of this. Just tell me." He gives you that look.
"Oikawa is coming to visit Japan and he needs a place to stay."
"And?"
You look at him with pleading eyes and he realizes immediately.
With big eyes, he steps away from you and the realization turns into deep annoyance.
Iwaizumi turns around to walk to your shared bathroom, he can’t deal with this right now.
"So does that mean you’re okay with it?" You call after him.
The only reply you hear, is a frustrating scream coming from the shower after a while.
"Eh, he’ll be fine." You mutter as you turn around to finish dinner.
The next day, Oikawa arrives bright and early at your front door, thankfully you’re both already awake, due to Iwaizumi’s early morning jog routine and you having the opening shift of the pharmacy.
A storm of the ringing doorbell makes the athletic trainer walk towards the door, and when Iwaizumi opens it, Oikawa jumps to hug Iwaizumi.
Not seeing in coming, Iwaizumi falls to the ground with a loud grunt, impacted by Oikawa’s weight.
"Get off of me you stupid idiot!" He pushes Oikawa off and can feel himself breathe again.
"But Iwa-chaaaaaaaan! I missed you dearly! Is this the way to greet your best friend who you haven’t seen in 4 years??" Oikawa pouts and when this chocolate brown eyes find yours, he yells your name out excitedly and runs towards you with alarming speed.
"My beautiful future best-friend-in-law looks gorgeous as always!" The giant Setter hugs you tight.
Giggling at his enthusiastic hug, you return it.
"It’s nice to have you here Tōru." You smile at him, parting from Oikawa.
"Come on, Shittykawa, let’s go on a seven mile run, like I do every morning."
The Setter pales like a ghost at that.
"But- I just got here and you’re already making me run? You can treat those mediocre third class athletes at the gym like that but not me, your best friend who just traveled half the globe to see you!" Oikawa tries to make an excuse but it doesn’t sit well with Iwaizumi.
"I am dead serious. Get your Argentinian ass outside, now."
Huffing in defeat, the brunette joins his best friend.
Now, originally Oikawa only meant to stay for a week, but one week turned into two and now the stay is reaching the third week.
In the beginning, it was only a stay because of training but now the practice time is over and before the real game starts, the coaches gave them two weeks off additionally.
You have the patience of a saint, really, while Iwaizumi feels each day his patience getting thinner and thinner. You can’t blame your partner, since he sees him at work AND at home.
The worst part for Iwaizumi is, he can’t have sex with you, because whenever he tries to seduce you or vice versa, the Setter seems to have a hidden talent on knowing when the two of you want some alone time.
On the couch, in the kitchen, the bathroom, you can’t even have alone time in your own bedroom because Oikawa is bursting in your bedroom every night, complaining and gossiping about every. single. player. while laying in the middle between you and Iwaizumi.
But now, even your patience begins to run out, your sexual frustration beginning to eat you alive.
So on a Tuesday night, you and Iwaizumi want to go out on a date, hopefully stopping by a hotel afterwards to relieve some of that tension. Or all of it.
And Oikawa wants to tag along, not wanting to be left alone in the apartment by himself, while the athletic trainer is trying to hint at his best friend that he wants to have sex with you.
"Why can’t I come with you?" The Setter whines.
"Because (Y/N) and I are going out tonight, we want some privacy to ourselves, because you couldn’t give us any for the last damn three weeks."
Oikawa nods.
"Just the two of us."
He nods again.
"Alone." Iwaizumi feels like speaking to a four year old.
"Alright, no problem, I’ll try to hit up Matsun or Maki." Oikawa whistles while making himself comfortable on the couch again, texting his former teammates.
Iwaizumi feels his anger rising abruptly, about to snap his neck and before you have to clean up a crime scene, you push your lover out of the apartment before an accidental murder happens.
In the end, you and Iwaizumi don’t even make it to dinner because you teased him during the ride, caressing his thigh up and down.
You don’t come back to the apartment for another two days, missing thousands of messages from Oikawa, enjoying each others bodies like you did the first time you got intimate.
