Work Text:
“Kacchan, c’mon, let’s go one more round,” Izuku begged. He stood in the middle of the training room, sweat actively dripping down his forehead, pleading for Katsuki spar with him. They’d gone three rounds already, full intensity, but something felt off . Izuku couldn’t put his finger on it, but he was determined to figure it out, even if it meant working himself to the brink of exhaustion in the process.
“Deku, I’m about to keel over from dehydration,” Katsuki said through gritted teeth, “I’m sweating too much to spar in here, my explosions would do too much damage.”
“Okay, we can go outside then-”
“Izuku. No. You’re about to pass out,” Katsuki said. He pursed his lips, giving him a once over as Izuku stared in shock.
“But-”
“No.”
“What if-”
“Shut up, no.” Izuku groaned and rubbed his eyes until he was seeing stars. The air was quite humid, the heat almost suffocating him as he tried to take a deep breath. The longer he stood still, the more scratchy his throat got. He was parched. He followed Katsuki towards the locker room, trying to ignore the itch under his skin that kept him from being entirely present.
Something was off.
The showers were vacant. Izuku stripped down quickly, eager to scrub the grime and sweat from his body. If only he could reach under his skin and scrub at whatever was bothering him, maybe then he could relax. He could hear Katsuki start another shower in the stall over. He sighed, running his hands through his hair as he massaged the shampoo into his scalp.
He just wanted to go one more round. Whatever the problem was, it was fixable. Maybe he was turning his leg to the side, opening his hip too much when he went for a high kick. Maybe he wasn’t staying on guard, forgetting to keep his hands by his head to protect from any blows.
As his mind continued to wander, the water started to run cold. He turned it off and slung a towel around his waist, heading back to his locker to find a change of clothes. A loud bang rattled through the room, the sound of a metal door being slammed shut with a ferocity that could only belong to Katsuki. Izuku huffed. He had all the energy in the world to destroy school property, but couldn’t spar one more round.
He went through the motions of putting his clothes on, his head not really there. It was somewhere else, thinking about combat strategies and techniques that he could possibly be screwing up.
“-eku. Deku!” Katsuki said, slapping him upside the back of the head.
“Huh?” he asked.
“I’ve said your name like ten fucking times. Are you ready to go study?” Katsuki asked. His bag was already on his shoulders, shoes tied and laced while Izuku stood in his underwear and a t-shirt that was inside out. The tag on the outside was waving like a little flag that signaled his idiocy.
“Sorry,” Izuku mumbled.
“It’s not gonna be my fault if you flunk the quiz,” Katsuki said. He waited silently as Izuku struggled with his shirt and tugged on his pants as fast as he could. The itch was still there, the nagging thought that he was doing something wrong. The more he tried to distract himself, the more it backfired, keeping his mind spinning in endless circles.
They made little conversation on the way back to Izuku’s dorm. The interest wasn’t there, and Katsuki was never talkative anyway. Izuku usually didn’t mind the quiet, but it only gave him more room to think, the one thing he was trying to avoid.
Settling in to do homework was even harder. Paragraphs seemed to jump off the page, go in one ear and out the other. He would read an entire page of the textbook and remember nothing . It was like the part of his brain that was supposed to intake information had just shut off. Every time he would blink his eyes would flick to something new, something irrelevant, and he would have to find his way back to the section he was reading before inevitably starting the cycle over again.
“What did you get on number twelve?” Katsuki asked. Izuku shook his head.
“Uh, I just finished number three,” he mumbled. Katsuki sucked in a breath. Izuku braced himself for a word lashing, but none came. Footsteps neared the bed, an added weight sinking onto the mattress beside him.
“Something’s wrong,” Katsuki said. A statement, not a question.
“No,” Izuku said.
“Liar.”
“Yeah.” He chewed his bottom lip nervously, unsure of how to proceed. How was he supposed to explain an imaginary itch? He moved his gaze to his boyfriend, hoping for any sort of leeway.
The way Katsuki looked at him never failed to make him flush. The intensity in his eyes was striking, his lashes a delicate blonde that became more visible in the sun. Only a few rays came in through the window, but his features were still well pronounced. Izuku took a moment to just stare , because it wasn’t often that Katsuki stopped moving long enough for him to just observe.
His brain was too cluttered to form an efficient response, so he did the next best thing. He pulled Katsuki in for a kiss, tugging him downwards in the process. Katsuki’s weight on his body began to calm his mind. The way he rested on his hips as their chests pressed tightly together was intoxicating.
A hand pushed on his chest.
“Izuku, what the-” He cut him off with another kiss, tongue flicking into his mouth and exploring soft lips and sharp teeth.
“I just need this right now,” Izuku said, barely pulling away. Katsuki seemed to understand, because he wrapped his arms around his neck and reciprocated. Izuku felt teeth on his bottom lip, sighing as he arched into Katsuki’s touch. He loved being underneath him, loved the feeling of his boyfriend pressing him into the mattress. There was just something about it that Izuku craved. It was like a drug. He inhaled through his nose, needing to kiss him until he could no longer breathe.
The blankets were soft beneath his skin, softer than the itch that had been plaguing him all afternoon. He settled his hands on Katsuki’s waist, squeezing to keep himself grounded. Their lips moved in tandem like they had many times before, not slowing when they slowly started to grind against each other.
“Kacchan,” Izuku whined. In response he got a sharp bite to the neck, one that brought tears to his eyes when Katsuki pulled away.
“Want to be inside you,” Izuku murmured. Katsuki wiped away his single tear with his thumb, sucking it into his mouth before nodding.
“If you wanted to fuck me you coulda just said so in the beginning,” Katsuki said. Before Izuku could retort, his shirt was being tugged off, pants and boxers following. The feeling of bare skin against the sheets was exhilarating. All the clutter in his mind continued to disappear as Katsuki kissed down his neck, all while removing his own clothes.
“Want me to open you up?” Izuku asked, propping himself up on his elbows. Katsuki shook his head, shoving him back down flat.
“Just watch.” So he did. He watched every single movement with close attention. Watching Katsuki stretch himself open was a beautiful thing, the way he absolutely fell apart under his own hand. Watching his fingers thrust in and out, not quite deep enough, trying to find his sweet spot but just missing. The squelch of the lube. He resisted the urge to take over, finger fuck him into the mattress until he was begging for his cock. But he stayed in place. Patient. Katsuki would give him what he needed.
“Lay back,” Katsuki said. Izuku shifted so his head was on the pillow, waiting for the next instruction. His boyfriend crawled over and straddled his hips, aligning the tip of his cock with his stretched hole.
“Is this what you want?” Katsuki asked. Izuku nodded. Frustration began to build as seconds ticked by, still feeling nothing but the rim.
“Kacchan,” Izuku whined. He lifted his hips off the bed, trying to thrust upward to no avail.
“Be patient,” Katsuki said. As soon as he began to sink down on his cock, tears bubbled in Izuku’s eyes, threatening to spill down over his cheeks. Katsuki’s face twisted into a sarcastic pout.
“Is it really that good?” he asked. Izuku couldn’t even form a response. The way he clenched around him was heavenly. His body sagged against the bed immediately, all his muscles going lax as he just let himself feel . The whirring in his mind was the most relieving. It all just stopped . The torment of never ending criticism faded away, leaving him with pleasure and the reassurance that Katsuki was there , and he couldn’t stop the tears from shedding as he let himself live in the moment.
It only spurred Katsuki on. His head was thrown back as he bounced up and down, strong legs caging Izuku in. He could barely see through his tears, but Katsuki took it upon himself to wipe them away. He leaned down, kissing the salt from his cheeks as he continued to ride him into a fumbling mess.
“Kacchan,” Izuku moaned. It was like a trigger had been pulled, and the tears just wouldn’t stop. It felt good . It felt amazing . The way Katsuki wrapped around his cock was invigorating and he never wanted it to end. The soft look from his boyfriend only made him cry more, small sobs leaving his lips accompanied by moans and whines.
“You look so pretty when you cry, Izuku,” Katsuki said. He sped up, slamming down against Izuku’s hips and meeting his every thrust. Both hands were on his chest, keeping himself upright as he used Izuku’s cock like a toy.
“Kacchan, I’m not gonna last,” Izuku cried out, lips trembling as he felt his gut tighten.
His orgasm shut all of his senses down. He could only feel Katsuki around him, could only feel his hole tighten as he inevitably came too.
A whisper in his ear.
“Izuku. Talk to me,” Katsuki said.
“Hi,” he said, flashing his best grin. Katsuki rolled his eyes and flicked him in the forehead, still sitting on his lap, cock slowly softening inside him.
“Do you feel better?” Katsuki asked. He used his thumb once more to wipe away any stray tears.
“Much better.”
