Chapter Text
Katsuki promised that the moment jealousy ever became a problem when Izuku started dating both him and Ochako that he would tell him immediately so they could work it out.
And so far, it had been pretty unnecessary. At least on his end.
It's been very understood that constant communication and transparency was the key to healthy polyamory, so the three of them talk about everything they feel they should to maintain the peace and happiness they share in their three bedroom house. Hell, Katsuki was already in therapy just so he could manage his temper and improve his communication with... well, pretty much everyone, but Izuku especially. Neither had ever been his strong suit, but at 19, he was more than aware of the fact that he needed to work on it if he ever cared to have friends or a career going forward in life.
At 20, he and Ochako started dating Izuku casually, and not long before Deku's 20th birthday also rolled around, he called them both to talk at his apartment. After the nerd turned 20, they caused a stir when Dynamight and Deku accompanied each other to the hero ranking ceremony as official dates. Not long before it was Ochako's 20th birthday, the rumor mill turned again when she and Izuku attended a Christmas gala together.
They broke the Internet shortly after New Year when the three of them came out as Japan's first open polytriad pro-heroes, with Deku becoming an instant bicon for Japan's Rainbow Community and Katsuki being the first pro-hero in all of Asia to openly be on the asexual spectrum. Providing visibility really balanced out some of the problems they faced against the country's more conservative and traditional mindset.
(Ochako sadly didn't have many upsides for her part when it came to public opinion. Many fujoshi either reviled her as being some "gross hetero extra" or started proclaiming her as their idol for "living the dream" until one of them had the audacity to try to get her to sign a BL doujin of Dynamight and Deku in front of Katsuki. He blew up the doujin, and it helped to solidify his friendship with Round Face. After that, it became clear there are some lines fans should just not ever cross.)
Their relationships grew with their careers, and it wasn't long before they decided to rent a home together.
Now, three years after moving in, 24-year-old Katsuki Bakugou for the first time ever felt jealousy rise from his romantic situation.
The real shocker was in how it manifested.
It was agreed between the three of them that each year, rather than trying to split individual Christmas Eve dates with Izuku, all three of them would keep attending Class A's annual holiday parties and platonically sleep in Deku's bed, which was conveniently large enough for all of them to snuggle in comfortably. The next morning, Katsuki would get up to make Christmas brunch while Ochako showered and Deku slept in, as he was always the last of them to rise without fail.
This year wasn't even particularly different. Not from the outside. But something in Katsuki had been slowly changing without notice, and when it did, it demanded it like a brick to the face.
This year, the party was held at a pension house just out of the city that Todoroki so generously rented with the hopes that those who had taken jobs further away would be able to come and stay. Katsuki, who never was a big drinker to begin with, volunteered to be their designated driver and watched with a small smile as Izuku and Ochako drank until they hovered somewhere between slightly embarrassing and kind of wasted. They even got Ochako to use her quirk on a sprig of mistletoe to catch unsuspecting victims. That made Katsuki look for the first opportunity to duck out, lest he be caught under with Glasses or some shit that would have his housemates laughing their liquored asses off. Thankfully, the one vice he had picked up, social smoking, brought him outside with Eijirou and Todoroki as they caught up.
"So how is it going with the three of you at home? I mean, I see what they say in the tabloids and all..."
Katsuki groans as he blows out some smoke.
"God, I don't even want to know what they're saying in those rags. They keep giving 'Chako so much shit, like she's just a bonus or a beard. How can she even be a beard when Izuku and I are out?"
Todoroki puffs his cigarello (the pretentious bastard doesn't change) and shrugs.
"I don't pretend to understand their logic. But from the look of things, I'd assume you're all doing well?"
"Stronger than ever, I think. When all this started, I just wanted to be with Deku and figured I tolerate Ochako well enough to go through with it. Now I'd argue I like her more than Shitty Hair here."
Eijirou clasps at his chest.
"Bro. Wounded."
"Eh, you'll get over it. What about you and Pinky Pie?"
"Mmm, amazing. But also kinda weird? She actually asked me the other day if I ever considered doing what you guys are doing."
That made Katsuki cough on his smoke.
"Fuck, really?"
"Oh yeah. She feels like she's holding me back since I'm bi and haven't dated anyone other than her."
Todoroki turns, "Wait, you're bi too?"
Katsuki laughs and pats Half-and-Half on the shoulder.
"Get with the program. Half of our class lands somewhere over the rainbow. But what's this shit with Mina? Does she want to make you guys open?"
"I guess? But like, just for my sake. When she brought it up, I thought my heart dove into my stomach, dude. Thought she was getting bored, but it turns out she has no intention of seeing anyone else if we actually did."
"Well shit. How do you feel about it?"
Eijirou looked off pensively as he took a drag, trying to sort out his feelings into the right words.
"I appreciate her being open to it, and I have at times wondered about if I'd regret never being with a man..."
"But?"
True to his nature as the absolute softest hard boy, a dopey grin spread across Katsuki's best friend's face.
"But I really can't imagine wanting to be with anyone as much as I want to just be with Mina."
Todoroki hums.
"Sounds like you have your answer for her, then."
"Yeah..."
Katsuki pats his friend's shoulder and turns to look inside the large bay window back at the party while he finishes his cigarette. Right at that moment, Ochako passes by to get more of the gin punch at the buffet table Rikido set up and, spotting Katsuki smoking on the veranda, gives him a warm smile and wave that tugs at his chest. Izuku joins her and makes a face when he sees that Katsuki is smoking, but blows him a kiss that Katsuki teasingly catches and tosses over his shoulder. He'll give him a real kiss later that'll have Izuku whining, both from want and the ashy flavor of tobacco. Deku feigns hurt, but smiles at him before Ashido calls out to them. The two of them look up and, lo and behold, they've fallen prey to the mistletoe trap Ochako herself had set. They glance at Katsuki for a moment before they lean into one another, Izuku cupping Ochako's face as he tilts her up into a slow, passionate kiss that makes the extra wolf-whistle and cheer, and Katsuki's stomach unexpectedly twists in discomfort and envy.
It's far from the first time he's seen them get lost in a kiss, and not even the only one where Katsuki wished he were a part of instead.
But for the first time ever, he wishes he was the one kissing Ochako.
The slowly growing realization that he may have developed feelings for his boyfriend's girlfriend haunt Katsuki for the next 24 hours. He lets Deku and Cheeks snuggle half asleep in the back seat the whole way back to their house, glancing at them in the rear view mirror and wishing they had just called a cab or something so he could join them in the back seat. Izuku stirs awake when he pulls into their drive way and offers to carrying Ochako inside, but Katsuki insists on being the one to bring the sleeping woman up stairs in a tender princess carry, looking longingly at her lips. She smells faintly of strawberries from the Christmas cake and he wants a taste so badly.
He shakes his head. Feeling such a strong sexual desire for someone other than Deku is foreign and confusing, and yet he feels warm and a little giddy at the idea of kissing this girl he's come to cherish awake.
Katsuki lays her down in bed, slowly undressing her to get her sleep clothes on, and he groans seeing her round tits in the lacey teddy that barely covers anything. It's really more like two strips of lace coming over her breasts and down to her crotch held in place by a few elastic straps. It might even be crotchless, as they only join over her groin with three tiny pearls and seem to split again. He's seen Uraraka naked before several times by accident, yet somehow the floodgates of his emotions and desires come full force and the lingerie makes his pants feel incredibly tight. Ochako hums and rolls over, one breast threatening to spill out of its flimsy confines and latches dangerously onto Katsuki's leg.
"Mmmm, sooo sexy..."
Deku returns to the room in fresh pajamas after his quick shower and voices his own lust, seeing what Ochako was sporting under her simple winter outfit.
"God, she's so gorgeous."
"Y-yeah..."
"Almost want to wake her up. She obviously planned for something tonight."
That makes the twisting feeling return to Katsuki's guts. Did she plan on seducing Izuku that night, even though they always spent the past Christmas Eves chastely holding their mutual lover together? Did she tire of sharing Izuku with a hothead like him? Or is it something else?
Katsuki counts back from five in his head as he gets up and pulls open a drawer for one of Deku's shirts. The top says, "Lucky Tee" on it and he snorts as he picks it up and maneuvers it onto Ochako, calming once the smooth curve of her breasts is hidden away. Out of sight, out of mind. (Hah, as if.)
"She should get her sleep, though. Maybe she'll initiate whatever she had planned for tonight while I'm getting brunch ready."
"Fuck, that'd be something," Izuku says with a hungry groan. He slips in under the covers on the other side of her and kisses her cheek tenderly. Ochako sighs and rolls over, clutching the nerd's arm and snuggling his bicep between her tits. He turns to Katsuki and smiles as he pats the vacant spot next to him.
"Do I get my Kacchan cuddles, too?"
Katsuki moves to the other side of the bed, pulling off his outer layers and not bothering with his sweatpants (though he should cover up his barely flagging erection) and climbs in while kissing his boyfriend deeply as he had planned to on the veranda.
"You couldn't even stop my cuddles if you threatened me with your damn quirk."
The next morning, Katsuki rose early as usual in spite of how awfully he slept. He normally sleeps so soundly on Christmas Eve, wrapped in the comfort of his lover and his best friend. Instead, draping his arm around Izuku brought attention to Ochako's warmth trapping his hand, the soft feel of her skin burning through Deku's t-shirt, occassionally brushing under her even softer tits. He's shocked that his boyfriend didn't awaken from the raging hard-on he was pressing into his hip as a result. He treaded out to his room for a change of clothes, showered quickly under cold water, and lightly padded to the kitchen, careful to not wake Ochako and Izuku before they were ready.
Though he usually gives them shit for drinking the stuff, he steals one of the energy drinks Deku and Uravity stock up on for overnight patrols before getting a proper pot of coffee going while he gets their food ready. It's the one day a year where Katsuki indulges them by preparing something individually for each of their tastes: a hearty Western style breakfast for Izuku with eggs and sausage, smoked salmon and eggs over rice with pickles and mushroom miso for Ochako, and an egg white omelet with peppers, sausage, and mushrooms for himself. Once he plates everything, Katsuki heads back upstairs to check on his housemates and stops when he hears a high moan of pleasure peal out into the hallway.
"Mmm, that's my girl," he hears Izuku praise. "So fucking wet and wound up for me."
"Fuck, Deku!"
Katsuki's throat feels tight, his jaw slack and panting as he pushes the door just so that he can look in.
Ochako is laying back in bed with Izuku's shirt twisted around her wrists. She's still wearing that lacy teddy that haunted his dreams last night, though one side has been tugged to the side so a pink nipple can be toyed by clever, scarred fingers. Izuku presses a smooth, thick thigh to the mattress to keep her legs open as he dives tongue first between the lace that most certainly isn't covering his girlfriend's pussy at all.
Before last night, Katsuki would be certain to describe himself as a homoromantic demisexual. Women generally fell far out of his aesthetic as a rule, having far more appreciation for the dense muscles and thick length that Izuku sports. Or maybe up until then, he was purely Deku-sexual, but he had no understanding of the attraction towards pussy.
Until he saw his boyfriend flicking his tongue rapidly over Ochako's clit, her pleasure dripping out of her very pink cunt, quivering and making him wish to press his own fingers in to feel her insides flutter as her hips shook.
Katsuki slid his hand down to tug his dick free and wrapped his fingers around his balls and shaft to keep himself from cumming at the sight. He can't recall the last time he got so wound up so quickly that he thought he'd lose it without a touch. Maybe the first time he watched Deku prep himself?
Izuku dives lower and thrusts his tongue between Ochako's folds and rubs his nose against her clit, eyes focused hard on her expression as she screamed with ecstasy.
"Oh my GOD!"
"Shhhh, you'll bother Kacchan down stairs if you don't keep it down."
As if to show how much he didn't actually mean to keep her quiet, he gave her bouncing tit a pinch, making the gorgeous woman bite her lip and tilt her back and she whined loudly. Izuku hummed, sending a shiver across her flushed skin and close his eyes as he got lost in eating out one of the people he loves most. A feeling Katsuki is familiar with, but currently wants to do with someone he hadn't looked at like this until recently.
That's when he started stroking himself, pressing his lips together to try and hold back his own sounds, hoping any slips would be drowned out by Ochako's unending litany of pleasure. He was leaking precum so much that his cock was slick and red and ready to go if he wanted to join in, but he wouldn't dare disrupt the gorgeous, pornographic sight before him. A flick of his thumb across the head and he failed to hold back a sharp gasp.
Ochako's head propped up, whether from the sound he made or a desire to watch the mop of green curls between her legs, he isn't sure. But her eyes connected with his for a second before she threw her head back into the pillows as she screamed out a long "FUUUUUUUCK," shaking hard.
Izuku kneeled up and hastily pulled off his clothes, plunging that fantastic cock Katsuki is so familiar with straight into her cunt, not letting Ochako come down from her orgasm at all. The bed shook hard, and so did Katsuki's hand as he pumped his cock in time with his boyfriend's brutal thrusts, imaging those convulsing muscles around his own length, Ochako's staccato "AH AH AHs" pressing on his fantasy until he felt his balls tighten and his cum shot out in thick ropes over his knuckles.
Clarity hits him, followed by shame and the urgency to clean up. With his clean hand, Katsuki pulls the door back closed just as Izuku grunts out his own release, Ochako letting out a soft squeal as she was filled with their boyfreind's cum.
Katsuki rushed to his room to clean off his hand and change his clothes before dashing down the stairs as stealthily as he could, scrubbing his hands clean in the sink and grabbing a glass so he can chug down some cold water. He takes a deep breath, then sits down in front of his plate.
"Hey, perverts!" He bellowed. "Get your asses down here before you let my hard work get too cold to eat!"
He hears the two of them giggle and scurry to put on some clothes. They're holding hands as they run down the stairs, Ochako wearing the sweater he discarded in Izuku's room the night before and Izuku wearing his licensed sweatpants.
Katsuki's heart feels light and warm at the sight of it, and fills him with both hope and dread.
For the sake of ensuring that they'd guarantee time off for Christmas Eve, Ochako's birthday, and New Years, they had all agreed to take patrol shifts on Christmas Day after noon. A small advantage for Uravity being in a different agency still while Deku and DynaMight have just opened Wonder Agency at the start of the year. Ochako headed first around 1300 to Gun Head's agency while Katsuki and Izuku snuggled watching Die Hard (a tradition between the two since their days at Aldera Junior High that Ochako didn't care for) until their shift started at 1500.
Ochako had a bad habit of dashing around at the very last second before she had to get to her train for her commute. It was standard and Katsuki did his damnedest to focus on Bruce Willis sneaking around in the vents of Nakatomi Plaza. Deku traced patterns on his leg, and it helpped immensely.
"Okay, I love you guys! I'm going now! " Ochako announced as she leaned over the couch between them, giving Izuku a quick kiss on the lips, followed by a surprising peck on the cheek for Katsuki before she pulled her shoes on and dashed out the door. Katsuki stared at her the whole way and kept looking at the door for a good while until he felt a hard pinch on his thigh.
"Ow! Fuck, what was that for?" he asked, rubbing at the pinch sight and glaring at his boyfriend.
"There's something off with you."
"What? No, what give you that impression."
"For starters, you were pressing some impressive wood into my hip for a good chunk of last night. I half expected you to feed me your dick or something when you woke up."
"I still could if you're up for it."
Deku looks like he's considering it for a second (thirsty nerd,) but shakes his head.
"Oh no, you're dodging. You promised you'd be good about communication when we started this."
"Fuck, yeah, I know."
"So, I'm going to guess from the staring you did just now and that look on your face when you were changing her last night, this has something to do with Ochako?"
Katsuki groans and pulls his legs up to hide his face into his knees, like the sad excuse of an adult human being he feels like right now.
"Yes. Fuck, you aren't upset by this?"
"Uhhh, why would I be?"
Katsuki turns his head and raises an eyebrow.
"Babe, she's your girlfriend."
Izuku shrugs.
"And you're my boyfriend. We all live together. I have taken immense joy in seeing you become best friends. Hell, I think you like her more than Kirishima at this point."
Katsuki laughs.
"Yeah, I actually told him that last night. So, me developing a thing for her isn't a problem for you?"
Izuku actually rolls his eyes, pauses the movie, and man handles him into facing him directly. Something he keeps saying about maintaining a serious position for serious conversations he said back when they started officially dating.
"One, it isn't my place to have a problem with you developing feelings for her. Not really. I'd be a hypocrite if I blew up over it when you accepted the idea of me dating you both. If it were a problem, I'd say it rather than be concerned for you. Okay? I love you both, no matter what."
Izuku gives Katsuki's hands a squeeze and pecks him on the nose and Katsuki lets out a breath he didn't even realize he was holding.
"Thank you."
"No need. And second, I don't think it's just 'a thing.' You're in love with her."
"Whoah, who said shit about love here?"
"Kacchan, you look at her the same way you look at me. You haven for quite some time now. You're just starting to add in the sexual element, I think."
That makes Katsuki stay quiet. Was that it? If Deku noticed it's gotta be true, and he can look back and agree now that they're talking about it. They did grew closer and closer these three years, especially after the doujin situation. He is even more vocal about his annoyance with the gossip magazines and tabloids when they criticized Uravity than he is with defending himself or even Deku. He just was slow on the pick up, though he'd argue this was relatively quick compared to the only other time he's fallen like this. This time it only took him three years to realize he was in love with someone rather than fifteen.
"I should have figured this would happen when I asked you two out, if we're being honest."
Katsuki laughs bitterly at that comment.
"You thought I was going to develop something for Ochako when you asked us to both seriously date you? Babe, we only just tolerated each other for your sake then."
"Well, I mean... You gotta admit, you have a type."
The fuck?
"I don't have a type. Aesthetic, sure, but Round Face sure as hell doesn't follow what has fit that."
"If your 'aesthetic' drove your sex drive, you'd be fucking Kirishima every chance Ashido would grant you. You have a type."
Katsuki's mouth gaps and shuts in shock at that comment. He's not wrong. Eiji absolutely fits what he's declared to be his aesthetic, and he certainly has strong emotions for his best friend since UA, but he never once developed a sexual attraction to him in the past eight years.
"Okay, if you know me so well, what the fuck is my 'type?'"
"Brawlers with big eyes and thick thighs who give you a smile as they don't take your shit."
Fuck, that checks out. The first time he had a wet dream was after his fight with Deku at Ground Beta after the provisional license exams, and he absolutely could not get over Izuku's bright eyes and delicious legs. Ochako never once just took his insults, and he loved that she didn't back down from a physical fight either, even before she interned with Gun Head. He did have his eyes glued to the shaking of her thighs that morning for sure as well. Her chocolate eyes melted him just much as Izuku's emerald uplifted him.
"...You know what, fuck you nerd."
"Maybe after you actually admit you are in love with my girlfriend, babe."
Katsuki groans and flops back on the couch. Izuku slides on top of him, toying with his hair in soothing circles.
"Fuck, okay. I'm in love with Ochako."
"I like it when you admit I'm right."
"No, really, fuck you."
"Not before patrol."
"...Do you think she likes me back?"
"Oh, Kacchan... You have it so bad."
He huff, wrapping his arms around Izuku and flips them over so he's on top. It makes the nerd purr under him, but they really can't fuck before work.
"So, I have to come clean... I watched you two this morning and jerked off to it."
Izuku blinks.
"Okay, kinda invasive, but also? Hot."
"I feel like shit for it."
"I'm sure we'll recover. You know, I'm like 100% sure now that Ochako had a plan to seduce both of us before she got so tipsy it made her sleepy. She talked so much about you during he party, it almost made me jealous."
Katsuki swallows hard. That would make more sense than her just trying to fuck Izuku when she knew that Katsuki would be in bed with them.
"Fuck, I thought she was actually sick of me and trying to seduce you into kicking me to the curb."
"She would never. You know that. You're just being insecure about it."
"You sound like my therapist."
"And you should probably just talk to Dr. Yomura about it before you self-sabotage."
"Nah. I mean, yeah, I'm gonna talk to her. But I'm not gonna play shit like I did at UA."
"Oh? Sounds like you're formulating a plan."
Katsuki slowly grins down at him and kisses Izuku, deeply but not for long.
"Hey, you do know me."
BOOM!
Dynamight stuns the three thieves from changing their escape route only to duck into the alleyway he knows Deku already has covered.
"I'll shoot! I'll do it!" he can hear one of them threaten his partner.
"I don't think so!"
BANG!
He dashes over to see Deku has completely dodged the panicked shot by kicking up onto the walls of the alleyway, bouncing around like that old man he interned with, pommeling the armed criminal with strong knees to the face, knocking him out on the spot. Deku knocks down the next guy with a back kick before he can retaliate with his tentacle-growing quirk (ew) and Dynamight grabs the last of them as he tries to draw a knife, twisting his wrist before throwing him over his hip and popping some warning blasts near his face.
"Don't even fucking think about it, asshole."
Deku finishes cuffing the first two and walks over to assist Dynamight with this jerk.
"So, okay, tomorrow she's gonna be stuck with her end of the year paperwork, so that gives us extra time to plan things out."
"We are seriously not talking about this right now, Deku."
"Yes we are. I have lunch with her during her break, I can drop the hints on your behalf then so it won't be such a shock on her birthday."
"Wait, are you two seriously talking about hooking up with some chick while you're cuffing me?!"
"See, even this guy finds this inappropriate."
"I think it's kinda sweet!" tentacles chimes in from down the alley.
"Shut your fucking mouth!"
"We can get the ingredients for her cake tomorrow! Oh, you know how much she loves strawberry shortcake."
"Duh, that's why get her one ever year."
"Yeah, but this time you should bake it! Cooking is like your love language."
"Wait, are you talking about Uravity? I thought she's dating jumpy over here."
"Sorry, he doesn't follow celebrity talk. They're a truple, moron!"
"Well, V triad right now, but—"
"ALL OF YOU SHUT THE FUCK UP!"
Dynamight can't believe this is his life right now. At least the police have caught up with them and are pulling the criminal trio into cars.
"GOOD LUCK WITH URAVITY, DYNAMIGHT! DEKU, YOU ARE SUPER LUCKY DUDE!"
"Aw, thank you!"
Deku actually waves to the tentacle thief.
"Wait, what's this about Dynamight and Uravity? I thought they're dating Deku?" one of the cops ask.
"AAAAAHHH!"
So, the plan is this: Ochako has to spend the morning at Gun Head's to finish some paperwork that needs processing to lighten the load before the full end of year report for their agency. She'll meet up with Deku for lunch before she has patrol, and then is spending the night at Tsuyu's before they and the rest of the girls go to a day spa to celebrate her birthday. Typically, she comes back from a day with the girls for a small dinner at home, then Izuku takes her out to a club and they come home for birthday sex.
This year, the boys are changing it up, now that they know with near certainty that Ochako wants to close their little triangle.
Since Katsuki and Izuku are free for the whole day, they plan to go shopping for Ochako's presents before Izuku has to meet up with her for lunch. Katsuki will take their gifts home, wrap them, plan a menu, and tidy up for a bit before his teletherapy session with Dr. Yomura. Izuku will go shopping for ingredients and decorations after receiving a text from Katsuki and come home right after his boyfriend finishes his counseling session. Izuku will play sous chef for Katsuki as he does what prep he needs to do the night before, which mainly consists of washing produce and clearing out used cookware. Maybe cutting and peeling, but Katsuki reserves the right to kick the disastrous nerd out of his kitchen and move him to continued cleaning and decorating duty.
That morning, Ochako gives Katsuki another kiss on the cheek as she leaves, this time lingering and far too close to the corner of his mouth to just be a comfortable gesture between close friends.
Izuku gives him a look as if to say, "I told you," before turning and kissing her with a confirmation that they'll meet at 1300.
This is going to go well. Now if only Katsuki could get the knots in his stomach to agree.
"No. Abso-fucking-lutley not," Katsuki mutters as he and Deku stand just outside Peach John. People are starting to stare and he wants to die already.
"Oh come on! I got some for her last year and she loved it!" Izuku insists and tries to tug him into the store.
"Izuku, you do not get sexy lingerie for a person you only just asked out for their birthday!"
"Alright, fine. But I am. She's been asking for some, and I'd love your input."
"Why? I don't know shit about women's underwear!"
"No, but you know Ochako, and you know what you'd both like."
Oh. Okay, that's a good point.
"Fine, but it's still all going under your name. I'll think of something for her while we look around."
"Deal."
Izuku takes Katsuki's hand and leads him into the store. Katsuki, for his part, still wants to die a little in embarrassment.
A sales woman approaches them.
"Gentlemen can I- Oh! Wait, you're Deku and Dynamight, right?"
Katsuki wants to cry, but Izuku is all charm and he hates him.
"That's us! We're looking for a birthday present for a special lady."
"Of course, of course. I'm a fan of all three of you. I'm assuming the lady is Uravity, yes?"
They nod.
"Luckily it's early and we don't have any other customers inside, so if you want, we can make your shopping experience a little more private?"
Katsuki jumps right on that.
"Yes! Dear god, yes, please."
The sales woman flinches a little at how eagerly he responded, but recovered and motions to another employee to stand by the door so they can shop in peace.
"Now, what do you have in mind for the recipient."
Deku glances around the shop pensively.
"She definitely wants some sexy pieces for her days off..."
"And something cute but comfortable for work. Preferably something that won't have lines showing through her costume," Katsuki interjects. Izuku smiles at his thoughtfulness.
"Oh, and maybe in our colors? Pink, black, green, and orange if those are available?"
The sales woman looks surprised at the inclusion of orange on the list, but they ignore it. Though, Katsuki will try to remember the face of the employee in case this comes out prematurely in the gossip rags.
"Mostly pink," he adds, again. "I think if she wants to wear our colors, she'll want that to be a surprise for us."
Izuku nudges him with an appreciative grin.
"Look at you, you're a natural at this."
He huffs in response and the woman nods.
"I think I have some good suggestions for you, then."
She leads them to some simple, wire free bras in soft colors and takes down a pink bra set to show them.
"This line is ideal for practical work, but the color and fabric choice is still very cute and this detail makes the cups look like a bow without compromising the shape. The panties have the same bow detail in the back, but given Uravity's belt, it shouldn't show at all through her costume. The thong cut will also hide the panty line better than other cuts."
She flips it over to reveal the lining in pink and white stripes. It really is cute.
"We'll definitely get this set. She'll love it."
The sales woman nods and adds the set carefully to a basket for them when she confirms the right sizes with Deku.
"Now, we also have our hero collection—"
"Yes!"
"Cool it, nerd. You know she's not into wearing merch like you are."
Izuku whines and the employee smiles.
"Well, while we do have some very, shall we say on the nose designs, there are pieces that are a bit more subtle that may interest you."
That doesn't sound to bad. Katsuki turns back to Deku, who is practically bouncing on his heels.
He sighs.
"Alright, whatever. This is your gift for her anyhow."
Izuku lights up and the sales woman leads them to the collaboration design. On the way, Katsuki stops at a mannequin showing a set that just screams Ochako to him. A simple pink bra with soft pink mesh embroidered artfully with stars over the cups, sheer mesh bands and matching panties with a mesh ruffle. He'll have to ask if that comes in the right sizes. He catches up with Deku who proudly shows off a black lace baby doll with thin orange ribbons crossing over the bust and a deep green mesh teddy with black lace appliques and a red velvet belt. Katsuki rolls his eyes, but approves.
He vetoes the disturbing All Might teddy.
"Nerd, I have something you should absolutely get for her."
He tugs Izuku along once the themed lingerie joins in the shopping basket and shows him the set on the mannequin.
"Oh. Oh my god, it's perfect. Are you sure you don't want to take credit for this one?"
Katsuki shrugs.
"We can share credit for that one. But it gave me an idea for what I really want to give her."
"Kacchaaaan, we've been hunting all morning and I'm gonna have to meet with Ochako in less than an hour!"
"Just one more shop, you shitty nerd! I know I saw it before on this street!"
The lingerie did, in fact, remind Katsuki of a necklace he saw along this way while helping his father find an anniversary gift for the hag. The piece immediately had him think, "That would be perfect for 'Chako." But, since they were shopping for his mother and he, at the time, thought it highly inappropriate to purchase fine jewelry for his boyfriend's girlfriend, didn't do more past that thought.
Now he was searching for it like a madman.
Katsuki spots what he thinks is a familiar awning and drags Deku into the jewelry shop.
This is it. This has to be it. In the back of the store is a familiar Tiffany-styled glass window of wisteria trees against a night sky.
"May I help you gentleme— oh, you're Deku!"
He groans and passes the salesman who is clearly his boyfriend's fan once again to ask for help from a different employee, spotting a woman with green coiled hair and glasses in the back.
"Excuse me, I'm looking for a very specific necklace I saw here a couple of months ago and was hoping it's still available?"
"Of course. Can you describe the piece for me?"
Katsuki gives a description of what he saw to the best of his abilities and the sales lady claps her hands in delight.
"Oh! Yes, that's one of my favorite pieces. I'm shocked no one has purchased it yet, come along."
She brings him over to the case where it sits, looking everything like he remembers.
"Fourteen karat white gold, pure pink morganite with blue topaz and diamond accents. Truly a gorgeous piece."
"It's perfect. I'll take it."
The woman swiftly puts the delicate necklace into a pink velvet box and places it in a bag for him once his card is approved. He fetches a flustered Deku from being shown the rings and thanks both the shopkeepers for their aid as they make their exit.
"Did you get what you were looking for, Kacchan?"
"Yup. And it's going to make Round Cheeks flip, just you wait."
"...Can I see it?"
"Nope."
"Oh, come on!"
If only either of them could notice they have a tail.
As everything continues with his plan, Katsuki's confidence about confessing to Ochako and asking her to go out with him rises. He manages to tidy up the whole of the first floor until every speck of dust is slaughtered and to make a perfect birthday dinner menu all by 1400. Deku calls when he gets Katsuki's shopping list before he has therapy and gushes about how unsubtle his girlfriend was when talking about Katsuki. Apparently she thinks his smile, the one that he only makes around them, is both a health hazard and a rare treasure. His therapy session went well, if embarrassing. Yomura thinks that, yes, they need to work more on his fears that he is not enough to want to be around, and yes, it’s very healthy that he isn’t denying his feeling but talking them through with his partner and is open to positive changes. Yes, she thinks his gifts show how thoughtful he is and he is making vast improvements with communication. He just needs to remember boundaries, and maybe reestablish what his own are with his partner. Partners, if everything goes as he hopes.
Izuku practically bounces around the house when he gets home, ready to decorate and help clean in his bedroom (just in case, and they don’t dare intrude on Ochako’s room without her consent.) They prep the ingredients needed together and store them away in tupperware before cleaning up again in the kitchen and wrapping up the presents. Katsuki again doesn’t allow Izuku to see before Ochako does, but this time the nerd relents and Katsuki adds the ribbon to the jewelry box, tying the tag and signing his name on it with pride.
They retire in Katsuki’s room early so they can finish the movie they ditched during their talk the day before and get a good rest before tackling the task of baking a cake together. Katsuki prides himself on being an excellent cook, but baking was never something he tried his hand at. He isn’t into sweets enough himself for it, and most of the ones that Ochako and Izuku are interested don’t require baking. The occasion cakes and rare pastries had always been purchased. So Katsuki was preparing for a full morning of careful instruction following and ensuring room and supplies just in case of mistakes.
It makes him anxious all over again and he reconsiders having a cake order on standby he can add his chocolate message on a store bought one still if push comes to shove. It won’t wound his pride to fail in his attempts.
That’s hilarious. Of course it will hurt his pride. Dr. Yomura is a therapist, not a miracle worker.
But really, how hard can it be? You mix shit in a bowl, pour it into a cake pan, toss it in an oven, then add whipped cream and strawberries, right?
“Has anyone told you you have some very loud thoughts?”
”I don’t want to hear that from a nerd who keeps muttering strategy before every single bust and stakeout.”
”Would you like to hear it from a nerd who is offering to eat you out like I did Ochako yesterday morning so you can stop overthinking?”
”Fuck yeah.”
You do not just mix shit in a bowl and pop it into the oven, it would seem. Katsuki was following the recipe as Izuku read the instructions to him aloud, and far too quickly, his boyfriend asks, "What does it mean to 'temper the mix in a double boiler?'"
"FUCK."
He should have over thought things before letting Deku talk him into being rimmed within an inch of his life. That way Katsuki wouldn't be cluttering around for an appropriately sized sauce pan sit the mixing bowl on top of and locate the goddamn cooking thermometer. (But with a tongue like Izuku's, who could resist?)
"It says to not let the water come to a rolling boil, but to a simmer to maintain temperatre? Oh, and you can melt the butter into the milk with the same method first while the water iheats up!"
"Not helping! Shit, where is the fuck is the thermometer?!"
"Don't we usually have it on the fridge? It's magnetized."
Katsuki looks up to the door of the refrigerator and sees the red electric cooking thermometer innocently stuck to it.
"You know what, fuck you. We should have called Sugar Man about this shit instead of fucking last night."
"He doesn't have the day off. You're just cranky because your ass is still a bit sore."
"Fuck you, I'm topping next time."
"Okay, maybe there's a video I can speed watch on YouTube so we aren't taken by surprise again..."
One ASMR backing video, one emergency shopping trip, and two temper-exploded cake attempts later found the cake cooling on a wire rack, sliced and de-crumbed and waiting to be decorated. Chocolate had already been blessedly prepared the night before, so Katsuki was just icing his message onto the chocolate card before getting to finishing all the cooking.
Right after he dots the "i" at the end of his name, his phone starts to buzz in his pocket. Katsuki pulls it out and answers.
"Who is it and what do you want?"
"Hey, Bakugou? Midoriya wasn't answering his phone..."
Shit, it's Raccoon Eyes. Why is she calling them? She supposed to be at the spa with Ochako!
"Nerd is washing some dishes and probably left his phone in his room. Why, what's going on?"
"There was something on a talk show playing on the TV here and Ocha just started bawling her eyes out and saying she wants to go home."
"What?! Fuck, what was on the TV?!"
"I dunno, but she's a mess and I don't think she'll be okay until she gets home to talk to you guys about whatever it is. Momo is livid. She asked the personnel to make sure we aren't bothered by any media for our reservation, but they had it going on in the nail salon."
"Are you sending her home then?"
"Yeah. Tsu already called a cab and is escorting her home. You might want to make sure that no press it outside, too."
"Fuck, how far are you guys from here?"
"I think it'll be about a hour's drive with traffic?"
Katsuki looks at the clock. They weren't expecting her to be on her way home for almost two hours from now.
"Shit. Nerd! 'Chako is on her way home, we gotta hurry! Thanks for the heads up, Ashido."
"No prob—" he hangs up before even letting her finish.
Izuku is wiping his hands and looking concerned at him.
"What's going on? You sounded panicked on the phone there."
Katsuki rips off his apron and storms to the door.
"Someone at the spa was watching some TV special where they talked about us and it made her upset. You go check the news and I'll make sure those vultures ain't waiting outside for us."
When Katsuki pokes his head outside, he's glad that there isn't a mob of press asking about whatever the fuck it was that is sending his girl home in tears, but he sees a rustling by the cypress plants and something looks off. Katsuki makes a show of closing the door and slides a pair of shoes on before throwing the door open and sending a blast right at the foot of the planter. A lizard-like paparazzo squeals in terror, clutching hard at his camera. He grabs the asshole by his collar and gets right in his face
"I thought I made it clear to you fucking rats that you don't bother us at home three years ago?!"
Katsuki can hear the guy lose control of his bladder. Fucking coward.
"I-I'm new! So-sorry, Mr. Dynamight, I-I'll keep it in mind!"
He drops the guy in the piss puddle he made on their walkway.
"Good. Get the fuck off my property. Now."
He watches the paparazzo scurry off.
"AND THAT GOES FOR ANY OF YOU OTHER LURKERS OUT THERE. YOU WANNA SCOOP WITHOUT GETTING YOUR BALLS BLASTED OFF, THEN YOU WAIT FOR THE OFFICIAL PRESS RELEASE!"
He slams the door and hears the echo of his bellowing coming from the TV in their living room. Izuku is covering his face, pretending he didn't see that happen on the new.
"Fuck, that was live?"
"Yeah. And now I know what made Ochako upset. Apparently, we went ring shopping yesterday. For eachother"
What? How did... oh fuck, that fanboy clerk was showing rings to Deku while he was buying 'Chako's gift. Either he blabbed about what he thought was going on or someone was following them and came to the wrong conclusion
"Fuck, this is a mess."
"What are we gonna do?"
Katsuki thinks for a second and returns to the kitchen, pulling the whipped cream and strawberries from the fridge.
"We continue with the plan and explain what happened to her when she gets home. But we gotta do this fast. If I have to cook after we calm her down, I will, but we gotta get this cake and her gifts set up first. Let her know we were thinking about her all day."
Izuku nods, moving into mission mode.
"Alright, just tell me what I need do."
"I SWEAR TO GOD, IF YOU DROP THAT SHIT, I WILL MAKE YOUR ASS MY COCKWARMER FOR A WEEK."
Deku stumbles in his dashing about, but catches all the dishes he's about to drop with One For All before he could make a mess.
"Hey, don't threaten me with a good time."
Katsuki snorts and finishes piping the cream border on top of the cake and places the strawberries and chocolate on top with a satisfied grin.
"Done!"
Dishes placed in the sink, Izuku returns to Katsuki's side to admire his hard work.
"She's gonna love it."
"Couldn't have done it without you, nerd."
Izuku smiles up at him and Katsuki leans down to kiss him.
And that was the exact moment that Ochako entered the house and saw them. Her eyes were wide, red, and teary as she stared at the two of them holding each other. It surely wasn't a new sight, but given the situation, Katsuki could see the hurt on her face none the less.
"Ochako! W-welcome ho—"
She drops her bag in the foyer, slips off her shoes, and runs up to her room, her soft sobs making Katsuki's eyes prickle as well.
"I'll go talk to her. You fix her shoes and bag and get out the gifts."
"Are you sure?"
He nods.
"Al right. Good luck."
Katsuki climbs up the stairs and knocks softly on Ochako's door before letting himself in.
"Hey, Round Cheeks."
Ochako sniffles and lifts her head.
"Hey, Asshole."
"Happy Birthday."
"Some birthday..."
He sits at the foot of her bed, approaching her slowly.
"Yeah, the nerd and I went all out to prepare a surprise for you. You just ran past it."
"Was the surprise the fact that you want to get married?"
There it is. Fucking media rats.
"Nah. Even if we wanted to, we'd talk to you about it before ring hunting. You know we would. That was the deal, remember?"
She rubs at her snotty nose with her sleeve, and Katsuki can't help thinking that she still looks absolutely gorgeous.
"So that was just a regular kiss down there?"
"You seriously didn't even see the cake, huh? Stupid. Yeah, it was a regular kiss."
"So the picture of Deku looking at rings..."
"We were shopping for you. Dumb salesman decided to drag the nerd to the ring counter when I wasn't looking and some shit with a camera took a picture."
Ochako laughs just a little.
"God, that really is dumb. I feel dumb."
"If it makes you feel better? I made another leech pee and run away after Ashido called and got caught on camera cursing out the rest of them."
"Oh no. Did they crowd he house?"
Katsuki gives her a feral grin.
"Nah, pee boy was just a dumb rookie who didn't know better. Don't know how many were actually out there, but they've learned to keep a safe distance of the house after the last time."
This time when she laughs, it's light and genuine and it seems to wash away all her anxieties.
"Just don't blow up the gate again. That was a really expensive repair, and we just put down for the house when you did!"
"I make no promises."
She rolls her eyes at him but sits closer to him and gives him a hug and he squeezes her tight.
"I feel like a mess."
"Welcome to the club. Wanna get back downstairs to the king dork of messes?"
"Yeah. Let's get back down to our hot mess."
When they reach the bottom of the steps, holding hand the whole way, the lights have been dimmed and Deku is placing another chocolate placard on the cake.
"Hey, what are you doing to my cake?!" Katsuki bellows, but there's no bite to it.
"Just adding my message, too, Kacchan!"
Ochako lets go of Katsuki's hand and he wants to reach back for it.
"Oh, leave him alone. Besides, it's my cake."
She takes in the cake, the chocolate obscured from the angle she's at so she can't read it just yet, and ends up distracted by the presents.
"Oooh, did you two go all out for me?"
Katsuki steps around her to block her from the boxes on the table.
"Nope. Cake first. Then you can open presents while I finish cooking dinner."
Ochako looks like she's about to use her quirk to float him out of the way, but Izuku cuts a slice and hands it to them with the placard facing her way, which makes her breath hitch. Katsuki looks quickly at Deku as he takes the plate mutely and receives a wink.
Fuck.
"Katsuki, does that say—"
He lifts the plate over his head.
"NOPE! You're clearly seeing things. Musta tired your eyes out from all the crying!"
"Oh, screw this!"
She activates her quirk on him, then on herself and floats to snatch the cake away from him grip so she can read the chocolate properly.
Happy birthday to the only girl I love. -Katsuki
Ochako releases them and tackles the explosive hero before they land, her eyes welling up with tears again.
"Katsuki, do you really mean that?"
"...Fuck yeah, Cheeks. I mean it. Been obsessing over how I just realized that I'm in love with you these past two days."
"It's been kinda funny to watch."
"Shut up, Deku," they say in unison and ignore their boyfriend laughing as they lean in to kiss each other for the first time.
As eager as she was to open gifts right away, the kissing was quickly disrupted by Ochako's stomach growling and Katsuki pushed her off so he could finish cooking the rest of the birthday feast he had planned. A spread of fried noodles, spicy tofu, dumplings, simmered chicken thighs, sauteed spinach and mushrooms, and savory traditional pickles along with a pot of rice.
"Has anyone told you before that cooking is your love language?"
"Seriously, you two need to stop trying to steal Dr. Yomura's job."
They dig in and the sounds of satisfaction coming from the birthday girl have to be Ochako trying to start something. Katsuki has now clearly heard her making is the "this mochi is delicious" moan and "Izuku's tongue is better than a vibrator" moan before, and this is absolutely the later. He looks to Izuku who, from the way he's adjusting his hips in his chair, is also picking up on what their girlfriend (god, that feels good to think) is trying to do to them.
"I think our girl wants her presents."
"Yeah, that and to get to dessert."
Cleaning the rice from her bowl and placing down her chopsticks, she gives them both a smile.
"Can't have dessert on an empty stomach, but if I had it my way, we would have started with it."
The look of desire on Ochako's face makes it abundantly clear that she isn't going dancing tonight.
"Deku, get the presents."
"On it."
He pulls the boxes back from the kitchen counter while Katsuki clears the dishes.
"Now, the big box just has my name on it, but Kacchan helped me pick them out."
"Oooh, I think I know what this one is. And Katsuki helped, hmmm?"
"You're both incorrigible."
Ochako carefully pulls apart the wrapping and squeals in excitement once the lingerie sets are revealed.
"Oh my god, this is more than I anticipated! I don't even know which one I want to wear first!"
Katsuki doesn't know either. Now that they're a thing, and she's gotten them riled up, he can't wait to see her peachy ass in these flimsy ensembles.
Deku seems to have an idea and whispers some filth in her ear that makes her shiver.
Katsuki grabs the pink velvet box with gold ribbon and slides it toward her.
"You nerds are filthy."
Deku sticks his tongue out at him.
"You're no better when you feel inspired."
Ochako smirks at him, knowing that she's inspiring him, before turning back to the jewelry box.
"This is what caused all the trouble on the news, isn't it?"
"No, a dumb fanboy and an asshole with a camera is what caused that shit. But yeah, this is from that store."
Ochako tugs the ribbon and lifts the lid, gasping softly as she sees the necklace.
"Oh my god."
Katsuki slides off the table and lifts the necklace out to put it on her. A pink morganite planet is orbited by a ring with a crescent moon made with tiny diamonds, and a topaz shooting star falls down the side of the chain, resting along her collarbones. She touches the precious pendant and it lifts up against her skin, reflecting light as if it were an actual star in the sky.
"Oh, Kacchan. That's so perfect."
"Told you, nerd."
Ochako releases the gift from her quirk and spins to give Katsuki a deep kiss in gratitude, pressing her whole body against his.
"Thank you. I love it. I love you."
Katsuki breathes out a sigh before diving back in. He feels another pair of arms wrap around both of them and Ochako squirms around between the two of them.
"You too. Love you. You're both the most amazing."
"You're amazing, gorgeous," Izuku corrects as he leans in to kiss her as well. The stretch exposes her neck to Katsuki and he leans in to have a taste, sliding his tongue up the side.
"Love you, 'Chako. Want you."
She whines and rolls her hips against theirs, feeling both their arousal.
"Fuck, I want you both so badly."
"Whatever you want, beautiful."
Izuku scoops her up in his arms, making her squeak in surprise.
"You carried her last time."
"Yeah, and you undressed me and everything, but didn't make a move? Feel like my efforts were wasted."
Katsuki's jaw drops.
"Wait, you were awake?!"
Izuku laughs as he makes his way up the stairs with the little temptress.
"Told you she was planning something that night!"
"You filthy, filthy nerds are really something."
"You love us!"
God help him, because he does. He loves them both so damn fucking much.
They break the Internet again with the announcement that their V-shaped triad is now a complete triangle on the anniversary of them coming out as Deku's romantic partners, and it's perfect.
