IcyHot liked you to believe he was a quiet person.
And in a way, he was. Like Katsuki, he didn't speak much if he didn't have to. And very much unlike Katsuki, whenever he did speak he kept his voice low.
But he didn't need to open his mouth to give you snark. No, somewhere along the way that boy had mastered the art of passive aggressiveness. He could ruin your entire career with a well placed eyebrow, a pointed slurp of noodles, a deadpan stare.
To most people, Todoroki’s bluntness and stoic facial expressions signaled either frigidity or naivete. But the more Katsuki was roped into hanging with him, Camie, and Inasa, the more he had come to realize Todoroki usually knew exactly what he was doing, and was enjoying the hell out of it.
The train ride back to UA was silent after they said goodbye to Camie and Inasa. They weren't the kind of people to need idle, pointless chatter. It was enough to stand next to each other until a seat opened up. When one finally did in front of them, Todoroki inclined his head toward it in invitation and stared at Katsuki until he sat down. Fucking… whatever. If Half n Half wanted to stand and stare out the window then who was Katsuki to save him from himself.
If there was one thing for certain, it was that Todoroki dressed like he had money. It was subtle, though. He didn't plaster himself in overpriced brand logos or anything like that. No, his style was that of the super elite, where everything looked understated and might pass as department store clothes. Until you realized that seemingly innocuous pair of slacks were actually Armani, that is.
Katsuki slouched in his seat in front of the boy, his own sweatpants-clad knees spreading a little so Todoroki could stand between them comfortably. His eyes roamed over the outfit— brown dress shoes and subtly pinstriped black ankle-length slacks to show off Ralph Lauren socks. A cream button down artfully untucked under a powder blue, well-fitted sweater. Even the thick black leather of his day bag, with its short handles and understated, rectangular shape that sat just under his armpit screamed money to anyone with eyes discerning enough to tell. All that wrapped up in a package that looked like your little sister's favorite Kpop idol.
Speaking of eyes, Katsuki dragged his gaze up to Todoroki’s face to find the boy already watching him.
Todorki stared at him, eyes half-lidded and eyebrow raised. He tilted his head slightly at Katsuki.
It wasn’t a tilt of confusion. No, this was a callout. The IcyHot bastard had caught Katsuki checking him out, and now he was calling him on it. Katsuki fought not to blush and held his eye contact. No way was he backing down.
It was Todoroki who broke their staring contest first, only to rake his eyes over Katsuki’s own body. Katsuki's wasn't sure what the boy saw in his own clothes— fitted black turtleneck tucked into black joggers into chunky white sneakers, with a bomber jacket over top and a gold chain 'round his neck because Camie would go on and on about how he needed one to complete the look if he didn't— but he gave Katsuki a small, satisfied smile when their eyes met again. To anyone else it would barely look like a twitch of his lips, but Katsuki knew just how devious that smirk was.
He looked down at his phone and scoffed, scrolling through who the fuck even cares what as he tried his damndest not to turn red.
Still, there were no more incidents for the rest of the way back. In fact, they'd settled back into their easy silence, all the way until 3-A's dorm came into view.
Before Katsuki could set foot on the porch, Todoroki grabbed his arm. It was a light squeeze of his bicep, more startling than actually restraining, but it was the way the taller boy bent down into his space that had him freezing in place.
"Come to my room," Todoroki whispered, his heated breath ghosting over Katsuki’s ear. He dragged his chilled hand down Katsuki's bicep before pulling away.
By the time Katsuki managed to reboot his brain, Todoroki was already inside.
Katsuki jogged up the steps before taking a deep breath, unwilling to step inside the dorms looking as harried as he felt. Todoroki was already gone when Katsuki stepped into the genkan, swapping his trainers for house slippers. He strode across the common room to the elevators, not sparing the people on the couches more than an off-handed wave. Once the chrome doors opened, he punched the button for Todoroki's floor instead of his own.
Seriously, what the hell was that bastard's problem? Fucking… that was him propositioning Katsuki, wasn't it? He was almost as pissed about how fucking smooth that was as he was about it happening in the first place. Like sure, he'd briefly entertained crawling into Todoroki’s bed with him before, but he wasn't nearly obvious enough about it to warrant that, right?
Okay. So maybe it was more than brief entertainment.
The elevator doors dinged open before Katsuki could really work himself up. He shoved his hands into his pockets and made sure to walk towards Todoroki’s door, keeping his footsteps light for once. More than anything, he hated that there were still nerves buzzing underneath his skin from such a simple offer, his hummingbird heartbeat refusing to calm down despite his best efforts.
He stopped in front of Todoroki’s door, taking another deep breath in the hopes that something would change. It didn't. He pounded on the door anyway.
"Come in," Todoroki’s deep baritone called back.
Katsuki pushed the door open, scowl firmly in place. He closed it behind him so they wouldn't get noise complaints when he gave the boy a piece of his mind, only for his scowl to melt away as he took in the IcyHot bastard.
Todoroki was laying on his bed, his sweater, shirt, and socks nowhere to be found. He had propped himself up on his elbows, strong shoulders fully on display. They sloped down into a smooth chest, only the faint hint of scars visible on his mostly unblemished skin. His position showed off his strong abs, adonis belt disappearing into his slacks, and—
Ah shit, his happy trail was half red, half white.
Katsuki’s thighs clenched around a sudden rush of heat. It wasn't the first time he'd seen Todoroki shirtless, by far, but it was the first time he'd seen him laid out like a particularly tasty snack. His eyes snapped back up to Todoroki’s face to see his head tilted invitingly, that pale neck on full display.
“What the fuck are you doing,” Katsuki asked, infuriated by how breathy his voice came out.
Todoroki raised an eyebrow at him, a what does it look like written clear across his face. “Strip,” he said.
“Fucking— what?” Katsuki choked, flaring red. That was too blunt, okay, what the hell.
Todoroki smirked, apparently satisfied with turning him into a tomato. “Katsuki,” he said, because he was the kind of freak who didn’t care about using people’s given names without permission. “Come here.”
Katsuki huffed, but slipped off his house slippers and jacket, making his way towards the bed. Todoroki sat up more once he planted a still clothed knee on the edge of the bed.
Katsuki leaned in until he could feel the other boy’s breath fanning across his face. “You’re a fucking freak, you know that, right?” he whispered.
Todoroki responded by kissing him.
His lips were warm, pushing insistently against Katsuki’s. He gasped when he felt a tongue press against the seam of his lips, giving the other boy access. His own hand came up to fist in Todoroki’s silky strands, the other planted on the bed to hold him up as Todoroki’s went around his waist. His mouth was warm as he licked into Katsuki’s— surprising, considering he ran hot himself, but he supposed that was the difference between his and a true fire quirk.
Todoroki pulled the turtleneck out of his pants, his hands resting against the bare skin of Katsuki’s waist. The dual temperatures made him shiver, his back arching slightly as the hands pushed his shirt up. Katsuki released the hairs in his grasp, sliding his own hand down Todoroki’s neck and across his shoulders. He dragged his nails lightly against the skin there, satisfied with the way Todoroki shuddered beneath him.
Of course that’s when the impatient ass stuck his hand down Katsuki's pants, sliding it down over his underwear until he could cup Katsuki’s mound.
Katsuki pulled back with a gasp, pressing their foreheads together. He panted as Todoroki dragged his fingers over his entrance. He gushed at the contact, his already wet underwear standing no chance.
“Fuck, you’re so single minded,” he said, rocking into Todoroki’s touch.
Todoroki pulled his hand back until he could get under Katsuki’s underwear properly. He went straight for Katsuki’s entrance, sliding two fingers inside of him. They were cool against his superheated insides. Katsuki moaned, shifting until he could bury his face in the crook of Todoroki’s neck, raising both hands to grip at his bare shoulders.
Todoroki pressed his lips just above Katsuki’s ear, crooking his fingers just enough to make Katsuki rock down onto his hand. Katsuki slid a hand down his chest, skimming over his abs and along his happy trail and fumbling with the button of his slacks purely by feel.
“Sit on my face,” Todoroki said.
Katsuki choked, his fingers fumbling. He pulled back enough to see Todoroki’s face, totally unchanged except for the slight flush of his cheeks. “What the fuck?” he replied, incredulously.
“What do you not understand?” Todoroki’s fingers crooked inside him again, caressing his walls and making him exhale shakily.
Katsuki shook his head. “You know I’m fuckin heavy, right?”
“Katsuki,” Todoroki said again. “I don’t know how to be any clearer than this. I want you to crush my head between your thighs.”
Katsuki’s laugh caught in his throat. “Shut up. Shut the fuck up,” he grinned, leaning in to kiss him again.
This one was much shorter. Katsuki pulled back, standing to take off his pants and underwear in one go. He couldn’t help the wetness between his thighs as he watched Todoroki suck his fingers clean before tugging at his hips, pulling him forward.
Todoroki pushed his shirt up enough to kiss at his belly, hands stopping obediently when Katsuki grabbed his wrists before he could hit the edge of his compression bra. Assured that he wouldn’t go any higher, Katsuki buried his hands in red and white hair as Todoroki dragged moist lips down his abdomen.
Still, Todoroki was a straightforward person. It wasn’t to kiss Katsuki’s belly that he wanted. He laid back on the bed, tugging insistently at his hips until Katsuki moved over him, knees planted on either side of his head. “Sit,” he said, hands sliding down to Katsuki’s thighs.
“Calm your shit,” Katsuki huffed. So what if he was enjoying the view of Todoroki under him, lips parted and eyes hungry? It wasn’t a crime to take a moment to appreciate it.
Smirking down at him, Katsuki spread his legs, lowering himself down onto Todoroki’s face. The boy beneath him wasted no time, licking a long stripe across his entrance.
“F-fuck,” Katsuki moaned, leaning forward to catch himself with one palm against the wall above Todoroki’s head. Todoroki’s hands came up to grip his thighs, holding him against his mouth as he began to eat him out in earnest.
Katsuki couldn't help the way his legs tightened around Todoroki's head. He was seriously concerned about IcyHot suffocating beneath him, not that the other boy seemed to care. In fact, he hummed his satisfaction directly into Katsuki's folds, licking up into him.
Yeah. All concern fled Katsuki’s mind, replaced by raw arousal. He rocked down onto Todoroki’s face, chasing that tongue. Todoroki was happy to provide, tilting his head up to reach even further inside him. Katsuki moaned, head dipping forward to find the other boy watching him with one bright blue eye and one gray one, both foggy with lust.
Fuck it. Katsuki felt like he was gonna sweat to death with the heat running through him. He unhooked the gold chain, throwing it only god knows where and grabbing the hem of his turtleneck. He practically tore the fabric over his head, throwing it to the side and planting his hands on the bed above Todoroki’s head. He used the leverage to rock harder into Todoroki’s face, grinding his hips down and shooting electricity up through his body.
“Fuck, Shouto,” he gasped, figuring the boy would appreciate that name more. The reaction was immediate, Todoroki groaning into his lips and renewing his efforts to eat Katsuki like he was the only meal he’d had in days.
Katsuki moaned, open mouthed and panting as fire sung through his veins. “Shit, Shouto, don’t stop, don’t stop,” he chanted. He was so close, so damn close.
Todoroki’s hands gripped harder at his thighs and Katsuki brought a hand up, grinding his fingers hard against his nub. The dual sensation shot molten lava through his whole body. He stopped breathing, the intensity of his peak causing all his muscles to seize. His thighs tightened hard around Todoroki’s head as he came, gushing all over his face.
“Fuck,” Katsuki exhaled shakily as the remnants of his pleasure washed over him in waves. His thighs shook where Todoroki held onto him. He knew he should get up so he could breathe, but he felt utterly boneless where he sagged on top of him.
Katsuki took several deep breaths before he could get his limbs to cooperate. Through sheer willpower alone, he managed to get up off Todoroki's face.
Todoroki sucked in a big breath once he could, chest heaving. He was a sight, eyes blown wide and mouth open, lips and chin totally drenched in Katsuki’s cum. Katsuki felt himself clench at the sight. Not that he had the energy to do anything about it— he felt like a puppet trying to operate with cut strings as it was.
Fuck, what did Todoroki want in return? After that brain-melting orgasm he just gave him, surely he wanted help getting off himself. “Are you expecting a blowjob or something?” Katsuki asked.
Todoroki shook his head, still looking only half present. “No, I’m good.”
Katsuki huffed. “What do you mean you’re good? Don’t you wanna get off?”
“Already did,” Todoroki responded.
Katsuki’s eyebrows flew up. He turned to look, and sure enough, there was a growing wet spot in the front of Todoroki’s slacks. He couldn’t help but laugh, delighted at his apparent power to make Todoroki cum untouched. “Fuck, you really are a freak!”
Todoroki hummed, blinking slow.
Katsuki flopped down beside him, pushing at his shoulder to get him to move. “Go clean up, idiot, you’re a mess. Hurry up.”
Todoroki turned his head to look at him, finally seeming to come back to himself a bit. “You’re staying here?”
Katsuki was already stripping off his compression bra. He’d promised Recovery Girl he wouldn’t sleep in it, after all. “Go, dumbass!”
Todoroki dragged himself out of the bed, heading towards the bathroom. Katsuki was already comfortable by the time he came back. Todoroki donned a fresh pair of underwear before turning off the lights and laying back down beside him.
That didn’t stop Katsuki from throwing himself over Todoroki’s chest, despite the frankly oversized bed. After that all he wanted to do was sleep, nestled against Todoroki’s heated side.
