slowly, but certainly, kirishima is beginning to see just how important his quirk is for the type of hero he wants to be. he is a shield; a pillar of strength and protection to those around him and with his hardening quirk, he's able to take on the worst of the worst and still come out the the other side swinging. it's this quirk that first caught bakugou's eye when he saw it in action and when kirishima displayed that power, proven time and time again his stalwart determination and drive to take on anything and everything in order to help others, bakugou knew this kid was going to be a mighty hero. a hero worth keeping his sights on.
but, there are cons to kirishima's quirk, the same as all quirks. the biggest flaw of it is one he's kept a secret ever since he realized it, and so far, the only person he's revealed it to is bakugou. it's times like that that kirishima is so grateful for bakugou being the extremely private person that he is, because he knows his boyfriend isn't a blabbermouth like SOME people ( mina and denki ) and the secrets shared between them are always locked safe. but that doesn't mean that, sometimes, when an opportunity presents itself, bakugou doesn't jump at the chance to take advantage of that specific flaw.
like right now, while he's got kirishima trapped underneath him on his bed, almost smothering him with the weight of his body ( bakugou's muscular, but still pretty slender, so it's not as if it's too much of an issue, especially considering that kirishima is just a little bit bigger than him ) and the redhead suffers a visceral twitch when bakugou's fingers absentmindedly stroke along his sides while the other hand scrolls along his phone. he hopes to god that bakugou didn't see that reaction, but bakugou sees everything because he's bakugou , and the way those stupid, pretty cardinal eyes of his look up at kirishima and just stare. in the same breath, the corners of his stupid, pretty lips perk and kirishima's entire stomach drops into his legs.
" katsuki ," the sturdy hero warns, but bakugou is completely, obviously , unphased.
"y'know, i'm kinda surprised at myself for not noticing this shit sooner, eijirou. " he bites back, playful, soft, all too smug for kirishima's liking.
"mhm, mhm - dunno what you're talking about." kirishima has never been a talented liar, something he hasn't ever necessarily needed to be good at, besides in situations like this.
"oh yeah? that's weird, cause i coulda sworn you told me a few weeks ago about how stupid fuckin' hypersensitive you are as a backlash to using your quirk so much."
kirishima swallows in a dry throat and nearly chokes.
bakugou grins, setting his phone down to the side of the bed in order to regain use of both hands, which plant themselves gently against kirishima's sides. the little jump under his fingertips causes bakugou's heart to flutter, his boyfriend is so damn cute .
a shade of red to match his hair paints over the skin of kirishima's cheeks, worrying his bottom lip into his mouth to fight off the smile that's spreading across his lips, knowing damn well it's only going to encourage bakugou to go on ( as if he doesn't totally want it too ).
" don't you dare ." he releases a final warning, much too lighthearted and on the verge of a giggle to be taken seriously.
bakugou's eyes widen and he shoots kirishima an incredulous look - one that absolutely says who the hell do you think you're talking to right now? he doesn't even need to say anything, because his expression tells it all, and he gives kirishima not an ounce of mercy for his insolence when he digs his waiting fingers into his sides.
the reaction is instantaneous; boundless, raspy, and delighted laughter pouring from kirishima's grinning, wide open mouth. he kicks at the blanket underneath him, hands shoving at bakugou's shoulders with barely any strength to it, because they both know he has no desire to escape.
"wahahAHAIT-! waitwaitwaHAHAHA-! KAHAHATSUKIHIHI!" kirishima howls, the entirety of his visage flushing that beautiful red.
"nah, no way, i wanna know who you thought you were orderin' around two seconds ago." he taunts him, flaunting that murderous grin he likes to wear, that kirishima loves to see even when it's focused on him, his fingers already beginning to travel towards his stomach, but not without hitting all the best landmarks along the way first, the secret little areas on his sides and ribs that make kirishima snort or squeak.
"plEHEHEASE! NOHOHO- CRAHAHAP, I'M SOHOHORRY―!" he has nothing to apologize for, he knows this, but he also knows that bakugou tends to show a tiny bit more mercy when you just tell him what he wants to hear.
unfortunately for kirishima, it isn't an apology bakugou's after, not after basking in his damn adorable glee. he wants to make kirishima squeal .
which, as soon as he finally moves his ticklish assault to his boyfriend's stomach, digging and scribbling into the softer parts of his waist, he's rewarded with just that. kirishima's squirming kicks up a notch as well, bucking hard enough that bakugou has to reposition himself after being shifted all askew.
"bAHAHABY― BAHAHAHABY , NO MOHOHOHORE!"
aw, shit. bakugou's face joins kirishima's in color, as it is annoyingly want to do whenever he hears kirishima call him baby. there's just something so tender and fuzzy about it coming from the redhead, like he fills every single syllable with as much love as his enormous heart can muster and it makes bakugou want to do anything and everything he asks of him.
so, as much as bakugou wants to continue and further reduce the love of his life into a blushing, tomato red pile of laughter, his fingers do finally begin to slow their movements to a full halt, simply resting against the clothed skin. kirishima's loud mirth dies down rto bubbly little giggles and he fully melts into the mattress underneath them, pliant and tired and delighted .
bakugou's eyes roll but there's a fondness sewn into it, moving to plop right on top of kirishima, the cheeky little shit, who responds with a groan and a chuckle of "ohohoof.. mercy, katsuki, im still in the recovery stage."
"oh whatever, you were totally asking for it." but he hides a grin behind his arm, only peeking out at the corners, just for kirishima.
"we'll see who's asking for it for next time," kirishima teases and relishes in the temporary flash of anticipation that twinkled in bakugou's eyes. "you're lucky i love you so much."
the blond exposes his smile then, crooked and warm, because how could he not be when he's with kirishima? in a voice softer than before, he answers, " ― love you too."
