Work Text:
Kirishima excitedly runs through the hospital corridors, even though the nurse has told him not to, and of course he will later apologize for his unmanly behavior, but he needs to get to the room where his new life begins.
When the number 209 shines above all the others, he takes a deep breath before turning the handle and entering inside.
He needs a moment to assimilate that behind that door his family is waiting for him.
Katsuki, his baby.
The baby he had been waiting so long to meet. Finally, after 9 long months of waiting, he is here.
"What must be taking you so long?" said with his head resting on the blond's huge belly.
Bakugou went from caressing his hair to hitting his head. "Dumb" he said to him when the thought escaped him aloud.
"Baby" moaned at the pain spreading through his head. Sometimes forgets how strong and heavy his husband's hand is
"Then don't talk nonsense and help me up. I have to get the damn dinner ready." Kirishima got up immediately, but not before leaving a kiss on Bakugou's belly, to comply with his request.
He followed Bakugou into the kitchen, restless in case something happened while wasn't looking and, despite Bakugou's grunts and curses because "shitty hair is fucking dinner,” managed to hug him from behind. His hands to his bulging belly and head to the blond's shoulder.
"Are you comfortable?" Bakugou gave him a sidelong glance, stopping his vegetable cutting for a moment and looking at him annoyed at his ridiculous worries.
"Yes," replied to kiss the blond's hair and hide in the crook of his neck, knowing full well that answer would only annoy his husband more.
"Not me, motherfucker. You're putting all your fucking weight on my fucking back..."
Bakugou would have continued cursing, had it not been for the hard kick that made him stop to take a deep breath.
"Kat" Kirishima tried to keep his voice from coming out mocking, but failed miserably as little giggles began to escape lips "our baby doesn't like it when you scold me."
"Tsss" Bakugou said as he bowed head and placed his hands on top of Kirishima's.
"You, spoiled brat. Don't always agree so much with this idiot."
"Hey" Kirishima nibbled on his neck to tickle instead of actual harm "I'm your idiot" showed his ring to emphasize point "for life".
Katsuki spun on his arms and the winning look gave his in response made breath hitch in his chest.
"Yes and damned if I didn't want it that way".
Smiling, he pressed body to his, careful not to crush belly, and kissed his red lips. "I love you, baby, both of you."
"And we you, hair for brains. Now go sit down while I finish getting dinner ready. I don't want you behind my back."
"Baby..." tried to protest, but stopped when the opposing hands flashed with little explosions "...I'll go watch Tv."
The wild laughter heard as left the kitchen left his heart calm enough to make worry about something.
"Ei, I know you're outside. What the hell is stopping you from coming in already?" Kirishima snaps out of his memories when hears his husband's overly happy voice.
He turns the handle and what sees, manages to steal his breath away.
"Ohh Kat, it's so beautiful. I... I... I can't believe that...! “ tears slide unbidden down his face as watches his cute little baby snooze on his husband's bare chest.
Bakugou watches in amusement as all the balloons escape his husband's hands due to the fact that his husband is busy trying to quiet his sobs.
"Shhh shitty hair" there is no real bite in his voice "you don't want to wake him up".
Kirishima repeatedly shakes his head and stops mid-step so that his heavy footsteps don't cause any more discomfort, even stops breathing for a moment.
"Don't be dumb and come closer" Bakugou shoots his a threatening look from the bed.
"But Kat" tries to protest.
"But nothing Ei, come closer!" the blond's raised voice seems to disturb the sleeping baby on his chest and it does, when the boy opens his round eyes and Eijiro's tears slide down his face again.
"Kat! Kat! Oh my god!" smiles big and happy as he says "He looks just like you!"
Bakugou's gaze drifts to the little person on his chest and a shit-eating grin immediately settles on his face as he sees why Eijiro says it so excitedly.
The tufts and spiky blonde hair tickle under his chin. He has to tilt his face just enough to be able to find what he's looking for.
And here...right here, he knows when his heart stops being his to hand it over, again, to another pair of red eyes that return an annoyed look for waking him up.
"I'm sorry baby" slides his hand down his child's bare back to comfort him "Daddy didn't mean to scream, but..."
He has to stop himself when another shriek coming from Kirishima brings his gaze back to him.
"What?" challenges him with his gaze, inwardly amused at disarming the redhead in this way.
"God! I love you! I love you!" Kirishima strides over to the bed and, careful not to disturb the baby who seems to be sleeping again, places a kiss on Katsuki's forehead.
"He is perfect and you..." kisses again, but now his lips "thank you, thank you for saying yes to everything. Yes, when I asked you to be my boyfriend; yes, when I proposed to move in together after U.A; yes, when I proposed to marry you and...
Katsuki's lips stop him from rambling on. The kiss is chaste, just a light, small pressure, but it still manages to make his heart race like crazy at what he feels.
Love, gratitude, happiness, commitment.
"Idiot" Bakugou still smiles. That wild grin that many consider anything but cute. But to him, to him it makes his legs tremble and falls to his knees before the blond.
"Thank you. Thank you for loving me when I didn't know how, thank you for not giving up on me when everyone else did.... "
"Kat" Kirishima tries to interject. Bakugou's manly words have his eyes watering again, but of course the blond won't let him.
"Thank you for teaching me that I can be number one, shine high; only if we all shine."
"Baby" complains Kirishima overwhelmed "did they put something in the anesthesia or....”.
"Bastard" replies Katsuki with no real bite in his voice. "Look what we built Ei" the happiness in his voice squeezes his heart "this is bigger, brighter than everything else" he breaks away and carefully passes the sleeping child into Kirishima's arms.
"It's our home."
Kirishima's breath catches and his brain short-circuits at his husband's beautiful, heartfelt words.
And not only does it look like Bakugou is trying to kill him with a heart attack, but his little baby decides to open his eyes again and a grimace, resembling a smile comes across his face, confirming his father's words.
