Chapter Text
Katsuki woke up with a splitting headache cleaving down the center of his skull. He groaned in pain and the sound turned into a whimper when he tried to roll over and the headache dug in deeper. He hugged the form in his arms, then jerked back when the form moved, revealing Izuku in bed with him, his naked chest right there.
“Kacchan, are you o-” Izuku cut himself off as he met Katsuki's eyes and saw something devastating there. His brows crashed together in worry and fear. “Oh…”
Katsuki sucked in a ragged breath and squeezed his eyes shut as the pain in his head doubled. He choked back a cry and rolled away from Izuku to press both palms against his eyes.
Then with a final crack, the headache broke, releasing like a snapped rubber band. He gasped in startled relief as the tension melted from his brain and he sank back against his pillow with a shaky breath, relaxing with a whispered curse.
When he was sure his head was back to normal, Katsuki moved his hands from his eyes and blinked the dark spots away before turning his head to settle his gaze on Izuku again. The nerd had pulled the comforter up to his shoulders and was blindly brushing his hands around in search of something beneath them, making sure to keep his eyes off Katsuki as he muttered into his bedspread about where something was, until an accidental glance up had him zeroing his gaze on that something just under Katsuki's shoulder.
“A-ah, um, s-sorry Kacchan, can I have…”
Katsuki shifted and eyed the bunch of fabric half under him. He tugged it free to reveal a pair of black boxer briefs that Izuku grabbed and quickly shimmied with under the covers. Katsuki's eyebrows rose straight up and his eyes widened as he realized that Izuku had been fully nude beside him.
Katsuki lifted the covers up and looked beneath them to see his own naked body. He registered Izuku's yelp and he caught the nerd scrambling to wiggle his boxers on over his half hard cock.
“K-Kacchan, listen, do you remember anything from the last f-few days?” Izuku asked frantically once his boxers were snapped up onto his hips. He pulled the comforter out of Katsuki's hand to cover them both back up again.
And, yeah, Katsuki remembered all of it. There had never been a question that he would, only about how he would react once the effects of the quirk were gone.
“Y-yeah…” he breathed, his heart jackhammering in his chest as he scanned Izuku's eyes. And holy fuck. Every fear and anxiety was suddenly drilling into his mind so loudly, it was like he had a whole construction crew in his body tearing him apart. He wet his lips nervously, watching as Izuku hunched his shoulders and pulled back a little, looking just as afraid as he felt.
And that was so wrong, it was so horrible to see his nerd afraid that he was going to hate him, that Katsuki immediately scooted closer, compelled to soothe him. He reached out and quickly slid an arm around him, earning a gasp from his nerd as he set their foreheads together, Izuku shuddering with quiet tears. “I remember. Izuku-”
“I-I'm sorry, Kacchan,” Izuku whispered miserably, his voice cracking hard enough to make Katsuki wince in sympathy. “I'm so fucking sorry. I should have never- I knew you couldn't consent and I- oh my god. Oh my god, I feel sick. Fuck-”
“Baby!” Katsuki rushed to interrupt him, raising his voice and leaning back to cup Izuku's face with both hands. His nerd jumped at the sound of the pet name. Katsuki took a steadying inhale and stroked his thumbs across wet, freckled cheeks as he lowered his voice again. “B-baby, it's okay, you didn't. You didn't do anything wrong.”
“K-Kacchan?” Izuku asked, his voice warbling.
“Just- just give me a second, okay?” Katsuki asked, closing his eyes and resting his forehead against Izuku's again. A harsh breath shook Katsuki as he tried to swallow down an unexpected sob of his own. “I just… Think I'm having a panic attack.”
“Kacchan,” Izuku gasped in surprise, his voice heavy with worry and affection. He scooted forward quickly as he offered the comfort of his closeness in reassurance. “Kacchan, no, it's okay, s-sweetheart.”
“Shit,” Katsuki whispered, huddling into Izuku's body and scooting lower to bury his face into his upper chest. Izuku's arms wrapped around him and Katsuki tucked himself in, sliding his arms around Izuku's torso to grab onto him. “Shit, I can't believe- If anything, I took advantage of you and-”
“Kacchan, I love you,” Izuku interrupted roughly, his voice raw with emotion. “I love you.”
“Izuku, baby,” Katsuki rasped helplessly. He closed his eyes and kissed Izuku's pec, pressing his lips against him hard. Then he kissed a spot higher, breathing harsh against that warm skin that hid firm strength.
The same skin he had kissed and licked enough already to know it intimately, and yet hadn't kissed anywhere near enough to never do it again due to something like his pride inhibiting him from being honest. The idea of losing this closeness with Izuku and going back to before made him panic more than all of his reservations coming back to him.
He swiped his tongue along the line of Izuku's collarbone and Izuku inhaled sharply, tilting his head back to give Katsuki better access and press into the wet heat of his mouth, and Katsuki moaned against him in want, dragged his tongue up along his throat as the strangely already familiar sensations grounded him, took over his panic and replaced it all with pure need.
He felt Izuku's length press into his stomach and his own cock thickened in response. He kissed his way hastily up Izuku's jaw, burning hot with pleasure as Izuku tipped his chin toward him, visibly yearning for closer contact, and Katsuki quickly gave it to him, sealing their open mouths together and kissing him deeply. Izuku moaned loud and powerlessly, completely defenseless as Katsuki licked into him, groaning with him as delicious heat bloomed through him and burned away the last of his nerves.
“Take these back off,” Katsuki rasped quietly, sliding a finger into Izuku's waistband, and Izuku whimpered in desperation or relief as he shoved his boxers down almost frantically. Katsuki lost his patience within a heartbeat and grabbed Izuku's ass with his whole palm, yanking him in close to grind their naked cocks together with Izuku's boxes still trapped around his midthighs.
Izuku quickly laved his tongue over his palm, slicking it up, then shoved his hand down between them to grip them both together, wet and slippery. Words tumbled from him uncontrollably as his eyes fluttered back in pleasure and he pumped his hand. “Thank you, Kacchan, oh god, thank you, thank you Kacchan. Oh-”
Katsuki cut his ridiculous thanks off with a forceful kiss that was immediately broken as he came hard in Izuku's strong, slick hand, his body jerking roughly as he shuddered into his orgasm, his face screwed up in choked pleasure until the taut pull within him snapped into loose heat with a long groan. Izuku sobbed as his own organ chased Katsuki's, his fingers squelching Katsuki's hot cum over his own cock, spreading it over them both, and Katsuki tugged Izuku's hair to bring him back into another kiss, stealing his breath until he was sucking in air with heaving inhales that Katsuki kept cutting off with another kiss.
When Izuku finally opened his eyes again, dazed with his pupils blown out, Katsuki let him breathe properly in order to catch his own breath and speak, his voice soft and hoarse as he gazed into green. “I love you, Izuku.”
Izuku immediately wrapped his free arm around Katsuki's neck, sobbing as he pulled him into more kisses. But when they parted briefly between each kiss, Katsuki found his baby smiling huge through his tears and couldn't stop himself from smiling back just as wide and helpless.
—
It was exhausting having his inhibitions back. Katsuki's head felt so jumbled and loud, so full of doubts and regrets and embarrassment, and somehow it just all made him tired.
The exhaustion almost helped. He almost didn't have enough energy to give a fuck about all the noise in his head. But it was hard. He never considered himself the type of person to second guess his actions and decisions, but now that he had seen what he would be like with total, real confidence, it was hard to be as self-assured as he once thought he was.
He wanted to keep acting like he had been for the past couple of days (yes he was very bitter it hadn't been a full week like they said it could be), but it was all just so embarrassing. He was now acutely aware that his fucking world seemed to revolve around Midoriya Izuku, and god, it was pathetic how much of a simp he really was.
It was like all of his inhibitions revolved around the nerd. His nerd, but still the nerd.
Like, without inhibitions, he could have gone out and actually killed some villains that deserved to die instead of just getting a comfy tour of the country’s flaccid justice system, but nooooo. Couldn't be a total badass motherfucker. Had to be whipped potatoes for the biggest, dorkiest, worst dressed mess-of-nerves nerd in the whole world (who was admittedly also the coolest person Katsuki knew after himself and All Might).
All Katsuki had done with his walls torn down was cuddle and fuck. Is this who he was? Sure, it was just a few days and those days had been atypically quiet in terms of villain attacks and crime, but still.
Whipped potatoes. Warm, gooey, mushy, (delicious,) and softer than butter.
Pathetic.
Luckily cuddling Izuku made him feel better, now that he had gotten used to that freedom. Which was why they were taking it easy the day after the quirk broke and just cooking in the kitchen together. Sort of. Izuku was trying to follow orders as precisely as possible as Katsuki hugged him from behind, growling commands into his ear and watching him fail to slice anything into equal sizes.
They had spent the Saturday morning exhausted and loose-limbed in bed after another round of extremely wonderful orgasms since neither was scheduled for patrol, which made it easier to keep his dick down even though it was pressed against a very sexy ass, and now Katsuki just couldn't stop touching him, and fuck, even if he was embarrassed as hell and afraid and full of every doubt in the world, he wasn't about to give in to that bullshit after everything. So yeah. The nerd was his and he was going to hold onto him, figuratively and literally.
“Why are you angling the knife like that?” Katsuki muttered quietly, clicking his tongue as Izuku turned a carrot into chunks instead of slices. Why was he in love with such a clutz?
“Sorry, Kacchan,” Izuku said, frustration tinging his voice. At least he was trying.
Katsuki glared at the vegetables in front of them for a long moment, thinking, then blurted, “look at it like controlling your quirk. The whole carrot or potato or whatever is 100% and you want to divide it out into 5% slices.”
“Ah! Like five percent hits of flavor!” Izuku gasped.
Katsuki stifled a laugh on instinct but then hugged him tighter and tried to relax, letting himself chuckle into his shoulder when Izuku's slices became near perfect. “Yeah, you got it…baby.”
Izuku pressed back against him and Katsuki could see the blush climbing up his neck, tempting him to kiss right behind his ear. And he knew what it was like to kiss there. Warm and sweet, it would cause a shiver to shoot up his nerd's whole body if he got the spot just right. He'd done it a few times this week now. And he wanted to do it again. And he knew Izuku would chase the shiver with a little tilt of his ass to press back-
Katsuki was nipping at his neck before he could let his reservations try to take over the desire to experience all of that pleasure, and sure enough, a soft gasp preluded a pleasant shudder, and Izuku's ass ground back at the same time he tipped his head, pliant and instantly needy despite all of their activity that morning. Katsuki hummed in approval, his thoughts all quieting down under the delicious flush of hunger building in him as his hands shifted to find the hem of Izuku's shirt.
A loud clearing of a throat near the kitchen bar top made Izuku jump in Katsuki's arms. Katsuki just pressed his mouth to Izuku's shoulder and slid his gaze over to glare at Iida with irritation. Uraraka stood beside him, looking amused and concerned at the same time, as if the worries she voiced the night before were still lingering in her despite Katsuki's reassurance.
“S-Sorry Iida-kun!” Izuku yelped, but maybe he had gotten used to not bothering to fight Katsuki off, because instead of pulling away, he just settled one hand on Katsuki's arm around his waist.
“While I do share the same concerns as Uraraka and have to admit I'm worried about how Bakugou will react when the quirk wears off, even if he had feelings for you before, which had always been rather obvious…I am looking forward to far fewer public displays of affection once this week is over,” Iida said, sighing like seeing a kiss was the worst offense he should imagine. It probably was.
So Katsuki lifted his head and kissed Izuku at the base of his jaw while maintaining his glare directed at Iida. “Quirk broke this morning, Four-Eyes. Get used to it.”
“It did??” Uraraka gasped, looking so delighted that Katsuki curled a lip at her. Why were his nerd and his friends such weirdos?
Izuku covered his face with both hands, only managing not to stab himself in the eye with the kitchen knife because Katsuki snagged it from his fingers in record speed.
“Oi! Watch your fucking hands when you're holding a knife!”
“Ahh!! Congratulations, Deku-kun!!” Uraraka cheered, giving a little jump and a clap as if Katsuki scolding Izuku was proof he was back to normal, all of her worries now gone. “You two are so cute together! Is it official??”
“Ah, y-yes! I mean-” Izuku said, trying to hide more of his face. Katsuki clicked his tongue and finally slid his arms off his nerd, turning back to the vegetables to slice them up in fast, easy strokes.
“Course it's fucking official,” he said gruffly, his face turning red. “Was official four days ago when I tried to tell you losers I loved him then.”
“I have to tell Mina!” Uraraka said excitedly. Katsuki called out a quick “Oi!” but Iida stepped forward, raising his hand and his voice to announce “Bakugou, if the quirk is over, you have no excuse for breaking protocol-” and redirected Katsuki's attention to shout “show me the damn rule where is says I can't kiss my fucking boyfriend!” all while Izuku wrapped his arms around his face and meeped at the new pet name.
