your husband wants to open your marriage, and kirishima has been waiting for so long
sipping lightly on the champagne you had ordered, you ignored the slight buzz running through your stomach. as much as you wanted to claim it was the drink, you knew it was the nerves.
you still wore your wedding ring, the green jewel sitting on full display. you turned it around to face your palm with a frown.
you were a wife, a wife to izuku midoriya, deku, the number one pro hero. you thought you treated him well, acting like a good little housewife for him whenever he went away.
however, you couldn't ignore the sutble glances you gave him every now and then. you weren't a pushover, no, but you let things slide under the rug when it came to midoriya.
the pieces of clothing you'd find tucked away in his draws when doing the laundry, the way he would hide his screen at the dinner table, too many late nights at the agency. you weren't stupid.
maybe you were, otherwise you would have left him, demanded for a divorce like mina and suggested and ran off. only, you had sat and listened to his excuses and his suggestions of how you both could work on the relationship.
you scoffed, like you needed to work on anything for him.
he'd suggested an open marriage maybe three, four months ago. tabloids had blown up after you agreed, 'pro hero deku seen courting fellow hero uravity!' 'deku seen with another woman, without wedding ring?' 'are the midoriya's still in love?'
you shook your head and pulled out your phone. you hadn't dabbled in dating, hadn't even thought of going through with izuku's idea until momo had suggested it.
“you should take him up on his offer,” she had texted your right after getting off the phone and listening to you rant about him for the seventh time. “go on a couple dates, see how quickly he comes running back to you.”
and so here you were, dressed up, covered in red. a passerby may have believed you were being stood up but you weren’t, you’d arrived almost half an hour earlier.
maybe this was wrong, maybe you should just call him up and tell him you weren’t ready-
“am I late?” you lifted your head, eyes dancing up the black suit with red accents that stood in front of you. he was taller, much taller that you or izuku, with his hair neatly slicked back, most likely freshly dyed due to the red stains on his forehead.
he held a bouquet of flowers, gripping the bottom of them so tightly you were worried they might break, and his other hand gripping the back of his chair.
you hadn’t responded since he spoke, too enthralled by his sharp teeth and the way the suit clenched around his muscles.
“no!” you jumped at your own voice. “no. sorry, im- you’re just on time.” you smiled and let out a puff of air, straightening yourself up.
“good. shit, oh- sorry, I was so worried i’d be late, didn’t want you to think of me standing you up.” he rubbed the back of his neck.
eijirou kirishima, pro hero red riot. you kept your eyeroll to yourself at mina’s obvious matchmaking. she had told you just how enamoured he was with you ever since he’d seen you at one of the hero galas.
of course, you’d never seen him so dressed up before. “you look stunning.” you smiled, covering your mouth with your hand to try and stop the blush running up your neck.
“im- mina said you liked red, so.” you shrugged, picking up a menu despite already knowing what you wanted.
“i’d like you in anything,” you raised your eyebrows, peeking at him and noticed the pink covering his cheeks.
izuku didn’t compliment you much, not when you’d go out to dinners and not when you’d been at home.
“if this date goes well, I might just show you in my winter wear.” you winked at him, and he let out a laugh in response. he shook his head and raised his hand for a waiter.
you furrowed your brow and bit your lip, ignoring the slight flutter in your stomach as you compared his actions to things izuku would do.
he wasn’t rude, but being number one had gone to his head and somewhere along the way he started figuring out he could do whatever he wanted, so usually he’d walk straight to the kitchen and order straight from there.
as the waiter came around, kirishima glanced up to ask you what you wanted, giving you the chance to snap out of your thoughts.
“uh- could I please have the cheese steak?” the lady nodded, sending you a polite smile before collecting your menus. it was a stark contrast to the way most waitresses would glare when you were with izuku.
“so,” eijirou was nervous. he wouldn’t admit it to anyone, because he didn’t want you to think he was worried and uncool, but god was he nervous.
staring over at you, his breath kept catching every-time your eyes glanced up at home. your jewlery doing nothing in comparison to the red over your chest.
he would have to thank mina for the suggestion.
“do you want to talk about it?” you knew what he was talking about but you hadn’t expected him to ask, no one had asked you about it.
“no, no.” you smiled up at him, “we’re on a date. I wan’t to talk about you.”
everything had been amazing. kirishima had paid for the dinner, even after you’d tried to pay, and he’d promised to let you pay next time. you couldn’t ignore the way it made your stomach tighten.
he’d even walked you to the front door, where you were sure izuku would have already had his guest come and go. meaning you wouldn’t have much time before he came down to see who you were with.
“I hope you had a good time. with me- I mean.” kirishima pursed his lips. you stood up two of the steps and only just reached the same height as him. he held your hand in his own and rocked it back and forth.
“I did,” you swallowed, ignoring just how nice he felt with your hand in his, how warm he was. “i’m really looking forward to the next one.”
you pulled him forward by his tie and pressed a chaste kiss to the corner of his lips, pulling back only for him to pull you back in, his lips stopping just before your own.
“please-“ he whimpered, letting you know that it was you that got to make the final move. you crashed your lips against his, wrapping your arms around his neck and feeling his clench the fabric on your waist.
the flick of the porch light made you well aware of your predicament, the both of you splitting a part as the door swung open.
izuku, shirtless and dressed in his grey sweatpants, arms crossed and staring down at the both of you.
“kirishima.” izuku nodded, completely ignoring you and staring the taller man down. if he was scared. eijirou didn’t show it and instead nodded back and turned to you.
“ill see you round, alright?” he waved and moved back towards his car, letting you turn your attention back to izuku.
