The door shut behind Katsuki with a quiet click. The Pro-Hero stood in the hallway of his apartment as if waiting to be invited further inside. He removed one of his clenched fists from his pockets revealing a crumbled scrap of paper in his left palm. Black characters that could be read as “Deku” just as easily as they could be read as “Izuku” stared back at him.
Katsuki clenched his fist, hard, incinerating the paper to ashes with an explosion in his palm. As soon as he’d done that, he instantly regretted it. Maybe he could have switched with someone else if he’d kept the paper?
“Fuck.”
How did he get into this mess? The alumni of Class A had gathered together for a holidays celebration every year since they’d graduated. Tradition dictated some kind of gift exchange, but usually it was in the form of a White Elephant. Katsuki could do that. He’d bring something he’d want and if all the gifts that were unwrapped before him were too shitty to be worth stealing, he’d pick his own. Win-win. No hassle. No real thought necessary.
Of course, things were never that simple for everyone else. Every year someone was unhappy with their final gift. Last year had been the worst. Yaoyorozu, like usual, had brought a gift that was way too fancy; a basket full of beauty and self-care supplies that greatly exceeded the max budget they’d put in place specifically to keep her from doing such a thing. Hagakure had opened it first, hugging it to her chest with concerning possessiveness for the remainder of the exchange. No one could see her face, but it was obvious that she glared at every person who looked her way for a potential “steal.” Luckily, no one was stupid enough to try to take it.
Until it was Uraraka’s turn.
Katsuki didn’t blame Round Face. He knew she’d grown up poor and those habits of sniffing out anything of value never went away. When it was her turn, a strange glint came to her eye and she went in for the kill. The second Ochako put her arms out for the basket, all hell broke loose. All they could see were tears and frantic sweater arms flailing in the air as Hagakure cursed their friend to hell and back. Honestly, no one knew the Invisible chick could swear so proficiently.
It took an intervention of massive proportions to convince Uraraka to let the other girl keep the gift even if stealing was, “in the rules!” The whole affair had left a sour taste in many people’s mouth and now they were doing a Secret Santa this year.
Which left Katsuki in this fucked up situation.
Unfortunately he’d missed the original draw, leaving him with the last name in the hat. And fate must hate his ass because it was fucking Deku. Of all the people he could have gotten, he got his rival turned fuck-buddy.
Katsuki’s face crumpled in disgust as he shoved his fist back into his pocket and walked over to flop onto his couch. He hated that term, but he didn’t know what else to call them. It was easier when the sex was a new thing; then he could pretend it didn’t need a label. But now it’d been months of casual, but increasingly more frequent, sex. He didn’t want to complain—there was nothing to complain about physically, that’s for sure, but something had been gnawing away at him. If only he knew what that sensation was.
That wasn’t the problem at hand, however. Right now, Bakugo had to figure out what to get that stupid nerd. It couldn’t be something stupid or obvious like some All Might merchandise. If Katsuki had to get Deku a gift, it was gonna be the best fucking gift he could come up with...within the stupid budget.
Secret Santas sucked. That was all there was to it. The chaos that ensued at the holiday party only proved it.
Like every other year, gifting was left to last event of the night and, just like all those other parties, they’d waited far too late to start. People had talked and joked long into the night resulting in the awkward situation where people needed to leave soon for morning patrols, while others still wanted to hold off the gift exchange so that people would stick around longer. As it was, more people than usual had been unable to come. Mina had done her best to collect their gifts and had promised to distribute them during the party, but there was still some fear that people would remain giftless.
Finally, the group had agreed to open the presents, so long as they did it quickly. Iida and Yaoyorozu were frantically going through the gifts to hand them out to their respective owners, asking each person to open it for the group to see before they left. Again, poor planning. People began opening their gifts at the same time, making it hard to see what everyone had received. Someone pulled out hand-knitted gloves, someone else pulled out a box-set of a popular anime, another person some new training supplies. In the mess of wrapping paper and “oohs” and “ahhs,” people struggled to figure out who had given what gift. Some people called out to their giftees, but some people were already halfway out the door, throwing thanks over their shoulders to the whole group since they didn’t know the identity of their “Santa.”
Katsuki only had his eye on one present. The small green box was one of the last ones to be opened, pulled from where he’d stuffed it as far back under the tree as he could. Four-eyes finally handed Deku the box, pulling the nerd’s attention from Uraraka’s gift of a set of bright pink pajamas to his own present. Of course, Deku had to be weird about it, carefully pulling at the tape so he wouldn’t ruin Katsuki’s perfect wrapping job. He watched Deku’s green eyes widen as he finally freed the plain metal picture frame before they began to well up with tears. Damn crybaby.
“Awww! It’s all of us!” Uraraka’s high pitch voice carried over the crowd. “Look! It’s changing!”
“Is that an electronic picture frame?” Iida leaned over to look at the present, having just finished opening his own gift of glasses cleaner and a glasses repair kit.
“With pictures of Class A, kero.”
“How thoughtful!”
Katsuki’s vision was suddenly blocked by Yaoyoruzu stepping in front of him.
“I’m sorry Bakugo, I guess your Secret Santa didn’t get their present to Mina on time. I’m sure they’ll be giving it to you in the next couple of days!”
“Whatever,” Katsuki muttered, pulling himself up to stand. He didn’t mind not getting a present. He’d succeeded in doing what he came here to do.
“Kacchan!”
The blond paused on his way to the drinks, allowing Deku to catch up. Izuku stopped when he reached his side, but didn’t turn to face him. Their shoulders brushed and Katsuki felt something fall into the pocket of his jacket.
“Thanks for the present.”
“Tsk,” Katsuki clicked his tongue, not looking Izuku’s way as he casually stuck his hands in his pockets to feel the smooth surface of the small bit of plastic sneakily dropped there. “Who said that was from me?”
“Some things you just know.”
With that, Deku flitted away to chat with Kirishima at the drinks table. Katsuki, on the other hand, stopped and slunk to the side, leaning against the wall as he discreetly looked at the item he’d been slipped. In his hand was a remote of some kind. It was black with a set of three buttons: a plus, a minus, and a power symbol.
Without hesitation he pressed the power symbol on, unsure how long to hold down the button or what it was for.
A loud yelp rang through the room, causing Katsuki to snap his head upward. Izuku was currently coughing, red punch creating a dark spot on the front of his sweater.
“Dude are you alright?”
“Yeah—ah—drink just went down—ha—the wrong pipe.” Izuku’s eyes suddenly went from Kirishima’s face to looking over the redhead’s shoulder, locking onto Katsuki. He’d seen that look many times before, but usually when no one else was around to see.
Holy shit. Was the remote for… a fucking vibrator?
Heat rushed to Katsuki’s groin as he pressed the plus symbol a couple of times with his thumb. Deku closed his eyes, his face twitching in what probably looked like pain to anyone else.
“Are you sure you’re okay? You don’t look so good, man.”
Izuku nodded several times, and Katsuki couldn’t help the grin that spread across his face. He didn’t hesitate to press the plus symbol again and then again. The reaction was instantaneous with Izuku gasping and bending forward to grip the table.
“Deku, are you alright?” Uraraka pushed past Bakugo in the hallway to rush up to Izuku.
“He said he was fine, but I don’t think he is.” Kirishima now had a hand on Deku’s shoulder in a supportive manner. It pissed Katsuki off to no end. Shit, maybe he’d gone to far.
“Really, I’m—nghn—fine.”
“Is it your stomach, Midori?” Mina had now joined the small group, along with Kaminari and Iida.
“No, I’m—” Izuku cut off again with a gasp. Katsuki went to press the minus button, but he may have been too late.
“Maybe it’s time you called it a night, Deku.”
“I must agree! Here,” Iida wrapped his arm around one of Izuku’s, “let me drive you home.”
“No, Iida,” Deku whined. “Really, I’m fine.”
But his face was now red and a sheen of sweat had built along his brow. Katsuki bit into his tongue. Damnit. He’d cut off his own fun too fast.
As they dragged Izuku away despite his protests, the other Pro-Hero caught his gaze once more. The half-lidded look called to him and Katsuki knew he’d be leaving the party himself sooner than he thought.
Katsuki walked up to the familiar door with an unfamiliar feeling. The burn of arousal in his gut and the tight hold of lust on his throat were their usual comforting selves, but deep in his chest another, uncomfortable feeling had settled in. It scratched at his ribs, too heavy in its seat on his heart to ignore. So ignore is what Katsuki did.
He clutched the small control in his left pocket, his right hand raised to knock on the door, before he stopped. With a smirk for no one else but himself, he pulled out the remote and turned it on again. A crash echoed through the apartment, reaching Katsuki in the hall. The Pro-Hero’s balls clenched at the sounds of frantic steps coming in his direction.
The door flew open, revealing a panting and flushed Izuku. He’d removed his stained sweater and undershirt, leaving him shirtless in the doorframe. Sweat slicked abs ended in a carved half V cut off by the tight jeans that clung to Izuku’s hip bones as if drawn on his scarred skin.
They didn’t bother saying anything. In one smooth movement, Bakugo had his hand tangled in Izuku’s hair, their lips locked in a harsh embrace and their bodies flush against one another, standing in the still-open door of Izuku’s apartment. The shorter man gasped into the kiss, his breath caught in Katsuki’s mouth, before his own hands were gripping Katsuki’s waist to pull him even closer.
Kissing Izuku came so naturally to Katsuki that it wasn’t hard to maneuver their bodies out of the doorway enough to kick the door closed with his foot behind them. Izuku maneuvered his hand up to pull on Bakugo’s collar in a pathetic attempt to remove his leather jacket. They untangled themselves for a second, just long enough for Katsuki to shrug off his the coat while Izuku impatiently pulled up at the edge of his long-sleeved shirt.
“Did you have to turn it on so high from the start?” Izuku muttered as he struggled with Katsuki’s shirt.
“Not my fault you couldn’t handle it.”
It took both of them to finally pull the shirt up and off Katsuki’s head, but then they were kissing again.
Before Izuku, lust had been a pain, both literally and figuratively. Katsuki didn’t have time for masturbation and it was never as satisfying as this. The hints of sweet spiked punch on Izuku’s tongue did nothing to hide his natural flavour. It was a taste Bakugo had become addicted to.
That. Shit like that was something Katsuki never expected when they’d started their...arrangement.
But this? The way their hands battled with the buttons and zippers of each other jeans while their tongues continued to explore each other’s mouths—that was something Katsuki felt more comfortable with.
Somehow, they’d made it to the bedroom. Perhaps Izuku was more aware of their surroundings than he let on. They had to separate to tug off their pants and underwear, which gave Katsuki the perfect opportunity to push Izuku backwards onto the bed, grabbing his legs as he went down to hold them up in the air.
“Kacchan!” Izuku’s voice sounded deliciously ragged and coarse in the sex-filled air. “The—ah—the vibrator—it’s still—”
The other man couldn’t finish his sentence as he moaned, deep and throaty, when Katsuki lifted his whole lower half up off the bed. From this angle, Bakugo could see the black silicone base of the vibrating butt plug. The vibrations from the sex toy jiggled Izuku’s perfectly sculpted ass and Katsuki’s cock jerked in arousal.
Without thinking, Katsuki thumbed the edge of the silicone toy and Izuku inhaled sharply. The taller man smirked.
“Gotta say, Deku, I didn’t expect you to be into this shit.” He pressed on the toy with just enough force to change the angle and depth slightly. Izuku moaned.
“It—hnng—was for you.”
“For me?” Katsuki’s voice was low and raspy as he leaned his body forward, settling himself between Izuku’s legs to hover above his fellow Pro-Hero.
“Secret—ahh—Santa!”
That gave Katsuki pause. The pieces connected in his head with a snap and he barked out a laugh. “This was your gift?”
Despite being already flushed with pleasure, the red calling card of embarrassment traveled from Izuku’s neck to the tips of his ears. Immediately, Izuku’s hands went from his sides to his ass, but Katsuki caught them with his own, causing Izuku’s lower half to fall to the mattress with a flop.
“Kacchan!”
“What do you think you’re doing, Deku?” Katsuki leaned forward even farther, bringing one knee onto the mattress on one side of Izuku’s hips before doing the same with the other. Now positioned just above Izuku’s cock, Katsuki put his mouth against the shell of Izuku’s ear. “If this is my present, then I get to say when it stops.”
Izuku froze, his body tense in Katsuki’s grip and radiating heat from below. “Ah—Oh—Okay.”
With that, Izuku’s muscles relaxed, although his hard cock twitched against Katsuki’s leg. The heat in Katsuki’s gut sank lower, and the thought that crossed his mind had his tongue darting out to lick his lips. How would Izuku react if Katsuki did that? Perhaps he should ask, but then again, where was the fun in that?
Katsuki leaned back, smirking at the way Izuku’s eyes followed his every move as he reached for the lube he knew Izuku kept hidden under his spare pillow. No, what was the point in warning the other man? He and Izuku weren’t the talking type, anyway. They said all that needed to be said with action.
Bakugo squeezed a healthy amount of lube onto Izuku’s stomach. He relished the shiver that traveled up Izuku’s body, knowing the lube probably felt cold on his scorching skin. Katsuki rubbed first two fingers and then a third in the small pool of liquid. Beneath him, Izuku did his best to adjust himself to separate his legs further to reveal his still-filled asshole.
As if this lube was for him.
With his strength, Katsuki had no issues holding himself up above Izuku’s chest with one arm as he reached his other arm backwards to press the first of his lubed fingers against his tight asshole. As his finger slowly but surely entered him, Izuku’s pupils widened.
“Kacchan?” The other Pro-Hero was breathless, his voice quiet but also full of lust.
The only response Katsuki gave him was a knowing smirk. Instead, he focused on working himself open, pressing against his insides with practiced fingers. Where did Izuku think he got so good at this?
By the time Katsuki had his third finger in his ass, Izuku was a shaking mess beneath him. A single drop of drool pooled at the corner of his open mouth, pupils still blown nearly to the edge of his irises. Whatever Deku was feeling now couldn’t compare to what he was about to feel. Katsuki knew from experience that nothing felt as all-consuming as fucking into your boy—person’s tight asshole.
Apparently, Katsuki was wrong. As he finally lowered himself onto Izuku’s waiting cock, his face twisted in both discomfort and pleasure. The real thing was nothing like fingers or toys. Pure electricity traveled up Katsuki’s spine, tearing the air from his throat in the form of a gasp. Izuku moaned underneath him, already bucking up into Katsuki with the impatience of a virgin. Part of Katsuki wanted Izuku to stop, he wanted to hold down the other man’s hips and take back control, but the words didn’t come.
Instead, Katsuki met Izuku’s upward thrusts with his own bouncing motion as he rode Izuku’s dick for the first time. Below him, Deku was getting even more impatient. His hands came up to Katsuki’s waist, his fingers digging into the top of his hip bones. Even without his quirk activated, Izuku’s fingers were strong enough to bruise.
Izuku’s breath was already ragged, his movements erratic much sooner than Katsuki was used to. He could only imagine what Deku felt with the vibrator up his ass and his dick inside of him.
“Kacchan! I’m—hnng—”
Katsuki leaned away, changing the angle at which Izuku’s dick entered him, causing both of them to gasp at the extra depth he could reach.
“Kacchan—I—”
“Yeah, Deku? You like that?” Katsuki’s voice was deeper than usual, scratchy from the moans he struggled to hold back.
“I—”
Suddenly, Izuku’s body tensed beneath him, his eyes squeezing shut and his fingers sliding down to Katsuki’s thighs as he screamed with his climax.
“I love you, Kacchan!”
Katsuki froze.
Deku, meanwhile, continued to grind into his ass, riding his orgasm, but Katsuki’s mind had stopped working.
“What the fuck did you just say?”
Izuku’s eyes slowly opened, still glazed over. “Hmm?”
“Did you just say you fucking loved me?”
At that Izuku’s eyes snapped open for real, fear filling his emerald irises and his mouth falling open.
“Wha—what?”
“You just said you loved me.”
“No, I—”
“So you fucking don’t?”
“No I do! I just—”
Katsuki leaned forward and pulled Izuku into a rough kiss, catching the rest of Deku’s words with his lips. Deku hesitated, like he always did, before kissing back with just as much intensity. When Katsuki finally released him, he was already talking again.
“You’re not mad?”
“Tsk,” Katsuki clicked his tongue against the roof of his mouth as he pulled himself up and off Izuku’s limp dick. He ignored the strange sensation he still felt inside his ass, focusing on flipping Deku over in one smooth motion. “Why the fuck would I be mad?”
“I thought we’d agreed to keep this—ah!” Izuku yelped as Katsuki pulled the vibrator out of his ass with one hand, while Bakugo covered his dick in lube with the other. “Casual.”
With his dick lined up with Izuku’s waiting asshole, Katsuki leaned over Izuku’s back to whisper in his ear.
“I never said that. Don’t go assuming shit, Deku.”
Without warning, Katsuki pushed into Izuku in one motion. The moan of “Kacchan” from Deku’s lip washed over his muscles, a warm shower of pleasure as Izuku’s heat wrapped around his dick. Even after having the vibrator inside of him for so long, his ass was as tight as always and it drove Katsuki wild. He set a quick, rough pace, with one of his hands in Deku’s hair and the other on his hip to keep him held up. Izuku’s thick Pro-Hero thighs were already shaking from Katsuki’s thrusts.
“Kacchan, I really do—I really love you.”
Katsuki’s dick twitched inside Deku without his permission and he began to pound into his lover harder. “Shut up, Deku.”
“I have for a long time.”
“Fuck,” Katsuki swore, feeling the coil of heat tightening in his groin. “I said shut up!”
“I can’t,” Izuku moaned, but the sound broke halfway through with a strangled sound. Of fucking course the nerd was crying now. “I’ve wanted to say I love you for a long time.”
Bakugo was close now; he could feel himself about to cum. He released Izuku’s hair, allowing the other man to fall into the pillows below while Katsuki curled his arm around the other’s waist to grab his once-again hard cock. Katsuki leaned his body weight onto Deku’s back, jerking Izuku off to the same beat of his thrusts. He was so focused on getting Izuku to cum before he did that he wasn’t even thinking about what he was saying.
“You’re not the only one.”
Izuku gasped in a mix of shock and pleasure as he finally came in Katsuki’s palm. After a couple more thrusts, Katsuki came too, his body suddenly heavy enough on Izuku’s back that they both fell into the mattress. They lay there panting, relishing the remains of their climaxes. Until Deku had to go and ruin it.
“Did you mean that, Kacchan? Do you really feel the same way?” Izuku whispered into the bed, making Katsuki roll his eyes.
“Think I’d lie to you, Deku?”
Deku shook his head into the comforter, his laugh muffled by the blanket.
“The fuck are you laughing about, nerd?”
“I just can’t believe...all this time...and we never said how we actually felt.”
Katsuki wrapped his arms around his lover’s waist, slotting his head in between the other man’s scarred shoulder and neck. “Who the fuck needs words.”
“They’re nice to have.”
“...Yeah, I guess they are.”
