------------------------------------

"Y/n don't forget, next weekend the four of us are having a girl's day. We already booked a table at a restaurant to have brunch with you and if any of them give you any shit you call me straight away." Mitsuki hugged Y/n for the third time, treating her like she would a child when leaving them all alone at home.

Mitsuki and Masaru were biding their farewells before they headed to the airport for their trip.

Earlier she went over a list of emergency contacts and letting her know where she could find defensive weapons to kick ass, in her own words. Not like Y/n would need them with her giant boyfriends, training, and her quirk – still, Mitsuki giving her motherly advice always made her smile.

Of course, she also had to warn Y/n that she would kick her boyfriends' asses (her son included) if they intervened with Y/ns time with her mother-in-law's. It was going to be just them and no one else.

Katsuki and Mitsuki had a lot of similarities, it was comical how much of a replica they were, even in their personalities.

Y/n smiling from Mitsuki's motherly kind gesture, hugged her back just as eagerly. Mitsuki always gave the best hugs, even if her personality said otherwise, she was a very caring mother. Tender, just like her son. Y/ns come to learn when the Bakugou's care about someone their demeanor is completely different. Katsuki's mother reminded her so much of her own mother from Mexico who she will never forget, and she considered herself very lucky to have Mitsuki in her life.

She will not take another mother for granted, and no matter the cost, Y/n will make sure to protect the family she was gifted with.

"Don't worry Mitsuki, I have you on speed dial. I hope you two have the best time." Y/n letting go of Mitsuki, then hugged Masaru.

The older man in affection patted her hair, ruffling it a little. "Take care sweetie, and please..." he whispered. "Make sure Katsuki doesn't burn the house down, he almost did once when we left him alone." He chuckled when he got a glare from his son who was leaning against the door frame next to his girlfriend.

Rolling his eyes at how doting they were being.

Frankly, that only happened once when he was ten years old and according to him it was all Izuku's fault. This happened during the times when they were best friends, and according to Katsuki, Izuku had gotten on his nerves. Now he was nineteen years old, soon to be twenty next year after he graduates. Still, even the gremlin of Katsuki Bakugou could admit how endearing it was for his family to love and care for his future wife as much as he did.

He appreciated the effort they put into building a relationship with her. Already imagining how his parents would be with their future grandchildren. Which was a topic him, and her other lovers would be speaking with her today. They all had to be on the same page if this relationship was going to last for as long as they all wanted it to.

And besides, Katsuki, Shouto and Izuku were already like family. They found Y/n to add to their already little group, and who knows? Maybe in the future they'll have more family members with their mixed genes.

Maybe not so far in the future with how Y/ns been acting with them.

"Alright we get it, you're going to miss her. Now get going before you miss your plane. You're hogging her." Katsuki grumbled, though on the inside he loved how much his parents accepted and took care of her.

Giggling softly, from his impatience, Y/n waved at them goodbye. Laughing at how Mitsuki threw a couple of profanities at her son for being so clingy while Masaru did his best to hurry her along to the car.

Closing the door behind her, Y/n leaned into her blond boyfriend's touch as he got closer. He may not be as tall as Shouto, but Katsuki was still huge and full of toned muscles. There was no baby fat on his body. Cut sharp, just like his vermillion fire eyes. A burning passion always shining in them.

Everything about Katsuki Bakugou screamed danger, even though he was a huge softie on the inside, and no one knew about it other than his family and close friends. Y/n was aware that even she sometimes had to tread carefully on the explosive minefield that was her boyfriend.

However, never afraid of him, she always willingly ran in.

"Katsuki, you can't be jealous of your parents." Cupping his cheeks she gave him a slow kiss, which turned much more passionate instead, leaving her breathless. Then groaning in annoyance when he pulled back.

"Hmm. You're bunking with me tonight." He grumbled softly and pulled her from her waist into his body. His large palms going under the shirt he gave her, kneading her soft skin. Kissing her cheek and then whispering into her ear. "I know you're probably sore, but that won't stop me babe. I've been waiting patiently for you. Don't you think I should be rewarded too?"

His deep voice was sweet, teasing. Her heart jumping from what he was insinuating.

Nipping on her ear after hearing her gasp, he continued as his fingers played with the band of the shorts, he also gave her. Damn did he love seeing her in his clothes. "You better stay quiet though, or it might make your other lovers want to join and we both know you're not ready for that yet."

Sometimes, he always said such the crudest things. But was she gong to complain? No. She loved all of him, even when he teased the fuck out of her.

Playfully he laughed from her dumbfounded expression. Loving how flustered and red she was from his comment. There were times he could even beat her and Izuku at teasing games.

"Katsuki... b-but..."

Cackling lightly, Katsuki gave her shoulders a reassuring squeeze to not have her freak out, "I'm just playing with you darlin. I'm not like half and half, I won't torture you... for our first time at least."

"Katsuki Bakugou!? I will kick your ass! I've been getting better!" Y/n playfully smacked him on his bicep before heading back towards the living room, where Izuku and Shouto were setting up snacks for their movie date.

Dinner went wonderful, they all pitched in when cooking, of course with Katsuki and Izuku teasing Shouto and Y/n for their little escape into nature. Creating a harmony only the four of them have. They were truly all a family. Even if it made no sense to outsiders, it did to them. They always flowed so well together, as though Y/ns known them for ages and not just months.

Y/n grumpily slumped towards the fridge and got their drinks before stomping over towards the couch, slamming the drinks down on the small living room table and unceremoniously falling face first on the couch, next to a chuckling Izuku.

The green haired man already knowing what would help her best ran his fingers through her hair as she grumbled incoherently into the couch. Shouto amused from her dramatics, smiled softly in her direction, giving a knowing look to Izuku.

"Alright shitty nerds, before I have to suffer whatever crappy movie damn Deku picked –"

"Hey!" Izuku huffed, half annoyed at how Katsuki smirked in his direction.

"– we should probably talk to this one about how horny she's been lately."

Hair disheveled Y/n glared to her very smug looking blond boyfriend. "I have not?"

"Sure, you haven't, tell me did Icy-Hot wear protection when you two escaped to the middle of nowhere?" Katsuki egged her on. Voice sweet and mocking.

Cheeks tinted pink with embarrassment, Y/n huffed, "No."

"Exactly." Katsuki not wanting her to run away, sat on the table in the middle of the living room, in front of the couch that she still laid down on.

Strategically, Shouto made his way to her left side to cage her in as well in case she did want to run away. Izuku was already on her right, which meant there was nowhere for her to escape now.

"All we want to know, is what you really want so we can all compromise." Izuku told her gently. His charming caring voice making her smile into the couch, she always did love hearing him talk. "We have an idea, but we want to make sure."

"Umm..." Y/n becoming flushed, situated herself correctly on the couch. Holding a pillow to her mid-section. Staring at the patterns as though it was the most interesting thing in the world.

Feeling their curious stares to what her answer would be.

"I've always wanted a family. I know we're young... and I don't want to pressure you... knowing you'll be fighting for the number one spot, there won't be time for children. That's why I didn't bring it up. I still want to be a hero with all of you. I would just like... to have a family too." She mumbled shyly.

Looking up she was met with a warm smile from Shouto who hadn't looked away from her.

Always such a gentle and kindhearted man

"We'll all be graduating in a few months and turning twenty next year. If this is what you really want, you know will give it to you. We want this life with you." Izuku mumbled, freckled cheeks dusted pink at the thought of his angel being pregnant.

Of having a family with her.

He was serious, he would protect her and the family they would all build.

"However, we do want to do this right with you. We've made jokes about marriage, just to fluster the fuck out of you. Still, we're serious about it." Katsuki's voice was so much tender than his usual gruff deep voice. "At least let us propose to you right darlin."

"We want to give you the world princess, and we don't want to wait any longer." Shouto, the sweet aloof man, smiled warmly at her – adding in his two cents, and making her anxiety ease up.

"How would that work though? Legally, I can only marry one of you?" Y/n mumbled, not liking where this conversation was headed to. "And I don't want to choose, I could never..."

"Who says we have to do it legally?" Katsuki stood up from the table he was sitting on, pacing in front of their little group. Always the commander this one. "It's only a piece of paper, right? If we, do it the way we want to. To us it will be real. We can do everything the traditional way; the only difference is it won't be in the government system. It would be just between us four. Of course, all of Japan would know, but fuck them and their opinions."

With how famous they all were already, and the line of work they were going into they would always be in the spotlight. Still, that wasn't going to stop them.

Y/n grinned at them, just the thought of his idea sounded so sweet.

Why should they follow how it's normally done?

Their relationship was never socially normal anyways? It's not like there were laws out there that protected relationships like theirs. Besides, she knows she is not the only one who has more than one partner. This isn't unheard of, yes, it's frowned upon, but who cares?

They could have a small wedding venue, without all the legal stuff involved. They would still treat it the same as they would a legal marriage, with loyalty and commitment. At the end of the day, marriage on a piece of paper was just for tax purposes and if someone died all the property would go to the spouse, but they could easily work around that through a will and power of attorney for all the other legal stuff.

Still, did they really need it?

No.

They trusted each other immensely. They already have their own hero company, that Shouto, Izuku and Katsuki were so kind to add her to, even though she was not present at the time of when their goal started. They still added her, because they wanted to be with her for as long as their life let them.

In a way, they were like a small family already.

Y/n was always fearful of not having anyone, ever. Because she's lost everyone. The only constant people she cared for in her life were her siblings.

Now, she had two more siblings. A caring doting father, and many more other adult parental figures who cared and wanted to be in her life. A lot of friends who were too, like a family to her.

Best of all, there are three people, who were willing to share her, who were willing to love her. Having their own relationship with her without feeling jealous from one another or making it into a competition.

Izuku, Katsuki and Shouto are a family, though one would deny it, and with the steps they took to become heroes together and support each other. They never thought of romance being involved into their busy lives. Their goal was simple, compete to become number one. Since finding Y/n, yes, things were not done in the traditional way, and they will continue to be done out of their crazy ideas through their relationship. However, that didn't matter.

As long as the four of them were happy, who cares what else the world thought.

Besides, Y/n was more than capable in taking care of herself, she proved that to them. They didn't need to be afraid of her being in danger, and there were three of them. Even if all heroes, they would all protect each other.

"As far as children goes." Shouto started, "There is three of us Y/n, any of us will be extremely lucky to be made into a father by you. However, think about carefully. They'll have three dads, which we don't mind, they'll experience more love and care than anyone has ever had. My question for you is, how many children do you want?"

"Way to bring the biggest dilemma in the room." Katsuki sighed out.

That was the million-dollar question, it was obvious how they all wanted a family. However, to what extent? It was a hard question to answer. Normally with one partner one could build a family with as many kids as they wanted. However, with three lovers what would be the appropriate answer?

Y/n was only one person, at the end of the day, she held the power here.

After a moment, Izuku was the first to speak.

"As hard as this is, we do have to talk about it. The only way this will work is if we all communicate and understand what we want. Shouto is right, there is three of us, but there is only one Y/n." Izuku told them honestly, grabbing onto Y/n's hand so she wouldn't pull on her fingers.

Giving her comfort from how pressuring that question was. However, as always, their understanding wife to be already knew the answer to their question.

"Well, I've always found luck in the number of three." Y/n mumbled quietly, giving them a shy smile from this conversation. Already imagining what each one of their little ones would look like.

Would they have Katsuki's passion and fire, his crimson eyes?

Shouto's beautiful two-toned hair and calm demeanor?

Will they be as kind as Izuku and decorated in multiple freckles?

Katsuki feeling her emotions in waves, scoffed amused and grumbled, "You're so fucking adorable. Stop that shit before I fuck you senseless and make your wish come true, sweetheart."

"Kacchan!" Izuku chastised him.

"Don't fucking Kacchan me, I can feel your emotions damn nerd, don't think I haven't noticed you eye fucking her earlier." Katsuki cackled when Izuku grit his teeth, successfully getting on his nerves.

"Are you sure Y/n?" Shouto asked her, while the other two bickered.

"Oh, trust me I know it's going to be a rowdy house. Still..." Y/n smiled when she saw Katsuki laugh from Izuku's attempts at hitting him. "I think it's going to be a beautiful life, much more peaceful than I had."

"And you'll be an amazing mother princess." Shouto took her hand in his and kissed her knuckles gently.

*****************************

Rapid knocks could be heard from the other side of Y/n's dorm room.

Who could be knocking so early in the morning?

Y/n tried to move to stop the person from the other side of her door. However, when she tried to move, she couldn't go far, she was trapped by three big warm boulders.

Oh, that's right...

Opening her eyes, Y/n was met by the angelic face of Katsuki who was sleeping peacefully.

Heart soaring, she smiled remembering the events from yesterday. They had truly given her something to look forward to. Her mind wasn't as clouded anymore, she still felt guilty, but they helped her out of her head.

They were truly all going to build a life together, the conversation was well overdue. This wasn't a fling. This was a ride or die relationship. They were willing to give her everything, and she in turn would do the same.

She looked over her shoulder when she felt warm lips nibbling on her skin, being gifted by the sight of Izuku smiling down at her, holding her tighter into his body. His forest eyes shining with love, green tresses fluffier than ever from just waking up. His palms kneading her stomach and hip.

He just couldn't help himself, after the conversation from yesterday, his head's been up in the clouds. Images of what a child of theirs would look like.

Was it crazy that he was already planning on starting a special book on tips and advice for their kid when growing up?

He'd been awake way before the knocking started, but he could not and would not leave his lover's side. If this is what Katsuki woke up to everyday, he would start asking Y/n if he could have his own days too. He was shy to ask at first, but now he didn't give a damn.

Y/n sleepily smiling up at him reminded him of a cute kitten when waking up, funny how Y/n thought the same thing of Katsuki.

Izuku never had this type of relationship before, he was raised to believe in waiting until marriage.

Now he wondered why it was so important to do that. He would rather have this every single day of his life, than to wait because of some old laws he didn't even believe in. And they were heroes, most of the time, heroes don't make it past a certain age.

There was something beautiful about truly living as though it would be the last day.

Besides, being here with Y/n, he wanted to experience everything with her. He didn't want to wait anymore. He wanted to graduate already so they could have her fully twenty-four seven and not sneaking into her room, so her father wouldn't find out about it.

"Morning angel..." his voice was full of sleep, groggy and deep. Hearing a rumble from his well-defined chest.

Up this close, Y/n could see all his birthmarks, Izuku didn't just have freckles on his face, they were all over his body too.

Kissing him under his jaw, she whispered. "Good morning my shooting star."

Y/n made sure to glide one hand on Katsuki's arm to keep him asleep from the noise outside. Usually, Katsuki would be out like a light, once she caressed either his back, or arms. Of course, he would deny it if asked. He had a reputation to uphold.

A low sneer came from underneath the bed sheets and Y/n and Izuku were met with a grumpy Shouto who was barely waking up. His body wrapped on top of Y/n, hence why she was having such hard time moving.

Pulling the covers up only exposing his face, a scowl on his prince like beautiful features greeted them. Ocean eyes narrowed into slits annoyed someone was disturbing his sleep this early.

"I will murder whoever is disturbing us if they don't shut up soon." Shouto grumbled still half asleep.
