Work Text:
It started casually in the kitchen. Katsuki had been rubbing his neck to try to work out a kink and Izuku, passing by, paused to reach out and gently press into the sore muscle without a word. Katsuki's knee-jerk reaction instinct was to snap at him, but the pressure of his warm touch was such a relief that he instead dropped his head forward and leaned back into Izuku's hands, groaning softly. If Izuku had laughed, Katsuki would have jerked away and kicked his ass for being so invasive, but all the nerd did was murmur a soft “right there?” And Katsuki hummed in contented affirmation.
He had never had a massage from another person before and holy shit, it felt glorious. A voice in the back of his head whispered that it was pretty fucking weird, and maybe if it had been anyone else, even a stranger, he would have hated it. But it was just Izuku and it wasn't like they didn't work in close quarters all the time as a duo-in-training. They were six months out from graduating and things were only going to get tougher going forward, so if they started managing each other's bodies, it was only so they would work better as a team.
Izuku moved his thumbs and fingers over Katsuki's skin with firm confidence, tracing small circles up his nape just below the edge of his hair, then sweeping down the sides of his spine to press hard into the middle of his trapezius muscles. And Katsuki just melted. Holy shit, holy shit.
“Holy shit,” he muttered aloud, and Izuku hummed in agreement, pressing the heels of his hands around the swells of his shoulders.
“You're really tight, Kacchan,” Izuku said softly. He stepped in closer and squeezed his broad hands down Katsuki's biceps, working his way lower. Katsuki lifted his arms so Izuku could knead his way down his forearms. He groaned weakly when the nerd clasped Katsuki's right hand with both of his own and dug into his palms with his thumbs. Katsuki hadn't even realized his hands were sore until that moment.
Izuku massaged his wrist and each finger carefully before switching hands and giving the other just as much care. Then he swept his touch back up Katsuki's arms and massaged the space between his neck and shoulders again before dipping forward to rub above his pecs firmly, just below his collarbones, bracing Katsuki against his own chest to get better pressure.
Katsuki didn't even realize he had sunk back against Izuku's chest until then. He blinked his eyes open and idly took note of the fact that Izuku's arms were practically around him, his nose just below Katsuki's left ear, ghosting warm air along the shell. As if noticing their position at the same time, Izuku finally pulled back carefully, stepping away to give Katsuki space as he dropped his hands quietly, his touch brushing the back of Katsuki's neck with a final buzz of pleasure.
Katsuki furrowed his brow and turned to look at Izuku, feeling loose and soothed and a little dazed.
Izuku bit his bottom lip, watching Katsuki with nervous, big eyes, blushing deeply. “Better?”
Katsuki rolled his shoulders and tilted his head a little. “Mhm. Thanks, nerd.”
“Anytime, Kacchan,” Izuku said, smiling softly, then he moved past him to find some lunch in the fridge.

After that, Katsuki moved and slept better than he ever had before. He was more than a bit disappointed when he felt himself tightening up again a few days later. And he couldn't stop thinking about the strange, pleasant warmth of leaning back in Izuku's arms. Arms he had collided into countless times in battle, seeking and giving safety in equal measure. Had he ever felt them around him without the burn of adrenaline giving them the excuse? It had felt good. All of it had.
But he couldn't just ask the nerd for a massage outright. That would be weird, right? And unfair. He was sure Izuku could benefit as well, but he never showed strain where anyone could see him, and Katsuki was oddly nervous to just approach him without the excuse. Sure he could just storm up to him and force a massage on him, telling Izuku that he needed to take care of himself too if he didn't want to fuck up on missions, but that wasn't the energy he wanted to give the nerd.
He saw his opportunity later that weekend. Most of the dorm had gone home, leaving the place much quieter than usual, and Katsuki had come down to the common room in the evening to find Izuku sitting at the coffee table working on planned vs spontaneous battle tax form homework. His head was bowed over the mock paperwork, his brow drawn in intense concentration as he referenced a handbook sitting to the side, and Katsuki watched him mutter about the different types of forms, rubbing his fingertips into his temple hard as he closed his eyes in frustration.
The couch was at his back and the room was otherwise empty, so Katsuki inhaled slowly and made his way over. Izuku looked up at him in surprise, offering him that pleased smile he always gave him, but then blinked in confusion as Katsuki stepped over the couch and settled on the cushion directly behind him, resting a leg on either side of Izuku.
“K-Kacchan, what-”
Katsuki gently rested his thumbs on the back of Izuku's head, turning him forward again and settling his fingers along his temples to begin massaging soothingly.
“Oh.” Izuku exhaled in weak bliss, immediately relaxing back against the couch to settle between Katsuki's thighs. He tilted his head slowly as Katsuki massaged his scalp and temples, coaxing away the headache, and when Izuku's head tipped back, Katsuki could see his eyes were closed in deep relaxation, the fringes of his lashes almost kissing his freckles.
Katsuki combed his fingers through his thick green curls, brushing them back from his forehead as he stroked along the arches of Izuku's dark eyebrows. Izuku sank further back, resting his head on Katsuki's thigh with a soft moan, and Katsuki lightly traced his fingers from his brows back to his temples, then down the soft sweep of his cheekbones to caress those freckles. He realized he'd never touched them on purpose before. Izuku's face was soft and warm, blushing beneath Katsuki's fingers as he eased his way across the areas where his own sinuses always ached, up the gentle slope of Izuku's nose, and then down along the lines of his jaw.
Making a full circle along Izuku's face, he pet up the sides of his cheeks and then massaged his ears, tugging at the lobes gently and rubbing the shells, unable to hold back a breathy chuckle when Izuku groaned in pleasure. Then Katsuki dug his fingers into his curls again, both rubbing at the tension in his head and brushing through the strands just to play with his hair.
“Feels so good, Kacchan,” Izuku moaned softly, such a shameless little bastard. He opened his eyes to look up at Katsuki with a hooded gaze and Katsuki snorted softly down at him.
“Haven't you ever heard of ibuprofen, nerd?” Katsuki asked, his voice low and husky. Then he nodded toward Izuku's homework. “What are you stuck on?”
Izuku sat up slowly, reaching forward for his papers without moving away from Katsuki's legs, and Katsuki let one hand fall down his back, swirling light circles between his shoulder blades as he reached forward with his other hand to steady the forms, leaning over Izuku slightly to read them.
“I can't decide how to classify a fight that was claimed by another agency but needed backup, at a charity event where I was also a donor.” Izuku shifted one shoulder back to tuck against Katsuki's chest.
“Calculate out your hourly rate and add it to the amount you donated, don't worry about the other agency if they didn't pay you,” Katsuki murmured, drifting his hand back up to tease the hair on the nape of Izuku's neck. It was so fucking soft and the little shiver from the nerd suggested he liked the sensation very much. “So long as-”
“Hey guys! What are you- oh shit, sorry!” Kirishima yelped as he came into the common room from the opposite staircase. Izuku jumped in guilty surprise, turning bright red, and didn't bolt across the room only because Katsuki settled his hand around the back of his neck to gently keep him in place. The nerd could still leave if he really wanted to, but it wasn't going to be because he thought Katsuki wanted him to leave. He felt Izuku swallow but then settle back into place.
“The fuck are you apologizing for?” Katsuki asked dryly, glaring up at Kirishima. Couldn't the dumbass check a room out before he just burst in? It wasn't like he hadn't walked in on other couples making out before, according to all of the anguished regret he had dropped on Katsuki and Kaminari during lunches.
Not that Katsuki and Izuku were a couple. Or making out.
“N-nothing,” Kirishima said, grinning awkwardly. “Um, I was just passing through. On my way to the gym. Wasn't gonna watch TV or anything! Yup!”
Katsuki rolled his eyes and finally sat back, letting go of the papers and pulling his hand away from Izuku with a final gentle tug of a curl.
“Relax and sit down if you want to watch TV,” Katsuki said, sparing his friend further grief by snagging the remote control and flicking on the television. He casually slouched back on the couch and Kirishima relaxed with a friendly smile, plopping into an armchair and catching the remote that Katsuki tossed his way.
After a few minutes of Kirishima’s channel surfing, Izuku leaned back against the couch, resting against Katsuki's leg and Katsuki hesitated only briefly before weaving his fingers through Izuku's hair again. Izuku melted, nuzzling his cheek on Katsuki's thigh, and Katsuki brushed through the strands affectionately, admiring the gem-shine of the tips and the dark, deeper emerald shadows at the roots. It was a beautiful shifting of colors, soft and glossy between Katsuki's fingers.
Katsuki caught Kirishima grinning at him out of the corner of his eye and looked over to see the dumbass giving him a thumbs up. Katsuki flicked him off, earning a wider smile, then rolled his eyes and focused back on Izuku while pretending to watch the action show Kirishima settled on.
Once the show was over, Kirishima flicked off the television and exaggeratedly mimed to Katsuki that Izuku was asleep. Katsuki waved him off, and once Kirishima was gone, he gently tilted Izuku's head back to free his leg. Standing up
“Hey, nerd,” Katsuki murmured, stroking those freckles with his thumb. What a stupidly cute feature to have. “Izuku, it's late…”
Izuku turned into Katsuki's touch but didn't wake, so Katsuki knelt beside him to slide his arms under his bulky frame. Izuku was still shorter than Katsuki, but he was a stocky, densely muscled son of a bitch, so it took a little effort to lift him up. Once he had him up, Izuku cuddled his face into Katsuki's chest before sleepily reached up to loop his arms around his neck, hugging him.
“Kacchan?” Izuku mumbled, still mostly asleep. Katsuki huffed a laugh.
“You faking on me?”
“Hmmm?” Izuku’s muzzy question turned into a soft snore and Katsuki chuckled quietly again, holding him tighter.
He carried the nerd into the elevator and up to his floor, then bumped Izuku's door open with his hip. He crossed the room, unfazed by all of the All Might merch, and settled Izuku on his bed, unwinding his arms from his neck despite Izuku's mumbled protests.
Katsuki really had no idea how such a vicious powerhouse of a hero-in-training looked so soft and adorable outside of battle. Except he kind of looked adorable in battle, too, even at his craziest. It was something Katsuki secretly liked about him. A lot.
He gave into the urge and swept his fingers into Izuku's curls, pushing them back from his forehead gently. Izuku smiled in his sleep, exhaling a soft “Kacchan…” that had Katsuki’s stomach swooping with butterflies. He pulled away hastily, feeling invasive since Izuku wasn't awake, then slipped back out of the room, closing the door silently behind him.

Izuku took his turn next, setting the cycle into full motion so Katsuki was able to pretend this was normal. This was what hero partners did. Took care of each other. Touched each other. Massaged Icy Hot muscle cream into each other's naked skin.
He had taken a really hard hit from a giant swinging clown mallet that had to be filled with fucking cement with how hard it was, right against his left hip, throwing his whole body out of alignment and leaving him limping. And of course Recovery Girl was booked for two days, no non-life threatening injuries allowed. Apparently the new first years weren't just accident prone, they had a student who could cause injuries with a thought and the dumbass had to have some intrusive and maladaptive daydreaming going on because he was two accidents away from being a villain. So far the “love and understanding” route wasn't doing jack shit and Katsuki predicted the dumbass would be isolated before the semester was up, hopefully before he killed anyone.
Hot showers helped, but Katsuki's back and hip were aching like a bitch and he was getting more and more pissed off at the looks of concern people were throwing his way. After a long shower on the second day, which always hurt worse than the first, he stood in just his boxer briefs in the empty locker room and awkwardly tried to spread pain relief cream along his side.
He glanced up when Izuku walked in, dressed in his hero uniform and looking pretty scuffed up himself, sweat holding his hair in place as he shoved his hand through the curls, sweeping them back from his forehead, exhaling in exhaustion. When his eyes landed on Katsuki, he smiled tiredly.
“Need some help?”
Katsuki untwisted his arm from behind his back and sighed. “Sure.”
Izuku removed his gloves to wash his hands and up forearms, pushing his sleeves to his elbows. He dried them thoroughly then stepped close to take the bottle. Katsuki watched him silently, taking in the faint bags under his eyes and the bruise on his jaw from a fight.
“You not sleeping?” Katsuki asked as Izuku squeezed some of the cream onto his fingers and stepped behind him. His strong hand gently stroked down the planes of his back, rubbing the cream against his skin in soothing circles.
“I am,” Izuku reassured him, setting the bottle aside to smooth both of his palms against Katsuki's back, down either side of his spine, to the lower dip of his waist. His hands parted to glide around Katsuki's sides, cupping his hips. “I just had turnaround patrol shifts last night and this morning.”
“That's bullshit,” Katsuki growled, turning as Izuku guided him so he could focus on his bad side. He got more cream and his thick fingers ran down toward Katsuki's hip. “Shouldn't wear us thin when Recovery Girl is unavailable. You injured?”
“Not as bad as you.” Izuku paused at the edge of Katsuki's boxer briefs, hesitating. Then his voice dipped a little lower. “Pull your waistband for me?”
Heat pooled in Katsuki's pelvis. He could reach this section. Izuku knew he could do this part himself. He wet his bottom lip and slipped his thumb under the elastic of his boxers to pull the fabric away from his hip. Then Izuku dipped his hand inside to massage into his muscle, his palm hot from the cream or maybe just from the friction, cupping his hip bone, fingers sliding dangerously close to either his ass or his hardening cock. Izuku stroked his hip gently, up and down the length of his upper thigh, deeper into boxers. Katsuki groaned, a dark, gravely sound.
“...Does it hurt?” Izuku whispered, sliding his thumb along the crease of Katsuki's thigh.
“N-no,” Katsuki moaned and couldn't stop himself from rolling his hips into the motion of Izuku's touch, rubbing his hard cock against the tented fabric in the front of his boxers. Izuku tightened his fingers into Katsuki's skin and a breathy sound of desire ghosted against the back of Katsuki's neck just before the locker room door slammed open and Mineta and Kaminari stomped in arguing about some actresses’ ‘assets.’
Izuku yanked his hand like suddenly the cream was burning him and stumbled back against the lockers behind him, turning around frantically to hide his front half as he dived into an empty compartment. Katsuki mirrored him, burying into his own locker, face blazing red as he grit his teeth, pissed off at the dumbasses who had burst in.
Mineta and Kaminari walked between Izuku and Katsuki without a fucking clue and Katsuki hissed in pain when Kaminari clapped him on the shoulder in passing.
“Sup guys!”
“Don't fucking touch me, dumbass!”
“Whoops! That's a nasty bruise! Sorry, man!” Kaminari ducked his head in apology as Mineta opened a lower locker to start shucking his costume, instantly killing Katsuki's lingering boner. At least until he glanced up and saw Izuku slipping away toward the showers, naked except for the towel around his waist.

Bakugou Katsuki had a secret, and it wasn't that he was in love with Midoriya Izuku. It was a secret that he planned to take to his fucking grave, even if he was tortured within an inch of life or if he was blessed with the chance to confess his feelings to the nerd. Even if the nerd miraculously and stupidly returned his feelings. No one could ever know. Especially not the nerd.
It was his greatest shame and embarrassment, but also something completely out of his control.
Bakugou Katsuki…found Izuku's feet incredibly sexy.
Even acknowledging it in his mind made him want to lay down in rush hour traffic or drown himself in the ocean. He wasn't some weird pervert with a foot fetish!
And it technically wasn't just Izuku's feet he found hot. He had caught himself drooling at those goddamn ankles and calves too. And yes, there were his tight thighs and trim waist, his ripped abs and chest, his powerful arms, his gorgeous face, his killer heartbreaker eyes. There was all that. Every inch of the nerd was a fucking wet dream.
But Katsuki's most frequent wet dreams involved those dorky-ass shoes hanging over his shoulders as Izuku's legs were bouncing in the air, or pulling those shoes off Izuku to reveal the strong arch of his foot and the hard knot of his ankle leading up to the delicious slope of his lower leg that his goddamn hero costume always highlighted for some maddening reason, or peeling off his stirrup tights and biting into his calf until the nerd was gasping and whimpering beneath him with his legs covered in bruising hickies.
Katsuki could just picture how Izuku’s legs would be at the perfect spot for his mouth to reach while he was dick deep in his pert ass. And he wanted to kiss the soles of his feet while fucking him in half.
Ugh, he was such a sick, fucking freak… No one could ever know.
And yet, one night, when he found Izuku dozing on the common room couch, stretched out on his back across the whole thing, freshly showered and wearing only a T-shirt and basketball shorts, his slippers discarded on the floor and his feet crossed at the ankles, Katsuki was too weak against the temptation. The TV was on, the volume low. No one else was around.
Katsuki slouched through the room, focusing on the television like that was what he was interested in. He picked up the remote and flipped the channels blindly, then casually glanced at Izuku, cupped his ankles to lift his legs, and sat down, resting his feet on his lap like it was the most natural thing in the world.
Izuku stirred when Katsuki touched him, rubbing his eyes tiredly before peeking one open to peer at Katsuki.
“Kacchan? Oh, sorry, I'll mov-”
Izuku cut himself with a helpless moan when Katsuki casually slipped his hand around one of his feet and firmly pressed his thumb into that alluring arch.
The bottom of Izuku's foot was unexpectedly soft and Katsuki wanted to kiss it so badly. He shifted to grasp his foot with both hands and kneaded into the ball, pressing under the toes so they spread and curled.
“Oh my God, K-Kacchan,” Izuku almost begged, his eyes fluttering shut. One of his hands slid up to grip his own hair and the other covered his mouth as he moaned loudly when Katsuki pressed his knuckles into his heel.
Izuku's other foot rubbed against Katsuki's thigh, sliding forward and backward as if he couldn't sit still and Katsuki let it explore, would get to it in a minute. He spread his knees a little as he dragged his fingers over Izuku's ankle to circle the swell of his bone before squeezing up his calf.
Izuku started to relax under the massage and Katsuki watched his face carefully as he stroked back down from his knee and swirled his thumbs into the arch again suddenly. Izuku groaned out, clearly sensitive on his feet, to Katsuki's absolute pleasure, and he arched into the touch, dragging his other foot up Katsuki's lap to rub possessively against his hard dick.
“Fuck,” Katsuki hissed, humping up against Izuku's neglected foot. He released one hand to reach down and clasp his other foot, stroking it between his palm and his cock briefly. Izuku pressed along the length, moaning lewdly as he peered at Katsuki in pure pleasure. Then Katsuki set Izuku's first foot on his shoulder and gave the other his full attention, lifting it away from his cock to keep control of himself and yet unable to resist bringing it up higher to kiss the inner side as he massaged it firmly.
Izuku's hand shot down from his mouth to his own cock, gripping himself hard over his basketball shorts, and suddenly he was gritting his teeth around a shout as his hips jerked and he came hard.
“I'm s-sorry, I'm sorry, I'm sorry!” he whimpered helplessly through his orgasm, like he had done something wrong but couldn't help it, and Katsuki shook himself out of his stunned stupor watching him to hurriedly kiss up his ankle and calf before he shifted to kneel between Izuku's legs and brace himself above him, each arm resting on either side of Izuku's head as he caught his mouth in a deep kiss that had Izuku sobbing. Katsuki lowered his weight onto him, rocking his cock against the tight quivering muscles of Izuku's stomach to get himself off so his nerd wouldn't feel vulnerable alone, then Izuku clumsily reached down to wedge his hand between them and cupped Katsuki's dick, immediately sending him over the edge, already so close from the intimacy of Izuku coming from Katsuki touching his feet.
Katsuki’s grunt of release turned into his own breathless whimpers against Izuku's mouth and he found himself mumbling “Izuku, Izuku,” over and over as he bit down his jaw as the pulses of pleasure rolled through him. He latched his mouth on Izuku's neck and bit and sucked him possessively until his pent up energy finally uncoiled and he slowly went slack, panting against the sheen of sweat on Izuku's skin as he finally noticed Izuku was stroking his fingers through Katsuki's hair.
Katsuki buried his face into Izuku's curls, tangling his fingers in the green locks as he cuddled against him. His lips found his nerd’s ear and he kissed and nibbled the lobe until Izuku was shivering with the overstimulation.
“Come stay with me tonight,” Katsuki whispered into his ear and Izuku gripped his hair tighter, nodding into his neck as he wrapped his legs around Katsuki's hips tightly, like he was trying to hold himself together. Katsuki nudged his face up and nuzzled his way across his freckles until he was sealing their mouths with another deep kiss.
