Shiny Things [NSFW]

As Izuku unwound a long strand of silver tinsel from the tree, he found himself smirking. It wasn't the strongest stuff in the world, he could tear it into pieces without even a second thought, but it was certainly very pretty.

Izuku liked pretty.

He reached for Katsuki's hand, getting a slightly surprised look for it that quickly turned into a sigh when he began to wind the pretty silver tinsel around his wrist.

"Am I the new tree or something?" he asked, the faintest of smiles tugging at his lips. "Need me to be fancy all of a sudden?"

"Pretty!" Izuku grinned, continuing to the other wrist to bind them together behind his back. "You're gonna be the prettiest Christmas husband ever!"

"Am I not already?" Katsuki smirked. "I'm not handsome enough on my own? I need cheap shiny trinkets now?"

"Kacchan is the prettiest! Especially all tied up for me to unwrap."

Katsuki finally caught on, groaning at his obliviousness as Izuku tied his wrists off with a big bow.

"You know I could break this shit without even using my quirk, right?"

"I'd be concerned if you couldn't, with those big, sexy biceps of yours. Look at these hot little beasts!" Izuku squeezed one firmly, delighted when Katsuki flexed for him. "But you're not going to, are you Kacchan?"

"Haah?"

"You're going to be good for me, aren't you, baby?"

Fuck.

Katsuki could never resist that tone of voice, the way Izuku dropped an octave and spoke so smoothly, so confidently - hell, that voice was the whole reason they'd even hooked up in high school in the first place, the catalyst for how they'd ended up married. 

"Answer me, Kacchan."

"Huh?"

"Are you going to be good for me?"

"Where's the fun in that?"

They exchanged smirks, both so sure of themselves, but Katsuki seemed to have forgotten one very important fact.

"Get on your knees."

Izuku knew exactly how to push his buttons.

His legs trembled beneath him - Bakugou Katsuki, greatest hero who ever lived, shaking with the effort it took to stay upright, to ignore the command.

"Kacchan is gonna be so pretty!" Izuku cooed, taking a red piece this time and looping it lightly around Katsuki's neck. "Down you go, Kacchan, I can't reach you properly up there!"

Katsuki didn't notice he was obeying until it was too late, a happy hum of praise washing over him as his knees met the carpet.

Fucker knew exactly what he was doing when he went for the throat.

Resigned to his fate, Katsuki let Izuku truss him up in shiny tinsel, his baggy t-shirt torn off without a second thought, in favour of looping the scratchy material under and between his pecs.

And yeah maybe it was fucking hot to feel the fabric give way so easily, to watch Izuku's lean muscles destroy the material like it was nothing, but he was hardly gonna say that out loud.

"Much better!" Izuku grinned, admiring the lattice of shiny, scratchy tinsel that adorned and emphasised Katsuki's godlike physique. "Look at you, all tied up and waiting for me! I thought I'd already opened all my Christmas gifts!"

"Guess you missed one," Katsuki smirked. "I hope you've got another one waiting for me, too."

"Of course, Kacchan!" Izuku's bright smile cracked, a hint of a smirk creeping in as he stepped closer, so close that Katsuki could faintly smell his sweat. His fingers reached a little lower, unfastening a button right in Katsuki's face. "Why don't you open it up?"

He laced his fingers in blond spikes, dragging Katsuki's nose to his crotch, and with a little snort, Katsuki obeyed. He took the warm metal zip between his teeth, dragging it down, and watched Izuku's fly fall open on a growing bulge.

"That's my good boy," Izuku hummed, dragging him back in until his nose rubbed against the warmth. "Open up, Kacchan. You can have your present first!"

"Fuck," Katsuki hissed, watching Izuku shed his pants and free himself from confining underwear, already hot and bothered just from seeing Katsuki bound and on his knees. "Someone is eager."

"Open," Izuku repeated, pulling firmly on Katsuki's chin to drag his jaw down, opening his mouth wide. "There's my good boy."

Katsuki stuck out his tongue, licking at Izuku's tip, and Izuku smiled as his thighs tensed up in response.

"Eager," he smirked. "Yes, someone is."

He slowly dragged his head across Katsuki's lips, watching fiery eyes cross as they watched, the little tongue darting out again and again to flick across a leaking slit. Katsuki had been a little surprised the first time he stuck Izuku in his mouth, expecting it to taste awful like he'd always heard, but it had been surprisingly tolerable. Izuku had sung his praises ever since, delighted that he'd managed to find a boyfriend who not only tolerated, but actually kind of enjoyed blowing him. 

It was about the power, Katsuki had always maintained. Feeling Izuku's thighs tremble as he went to town, watching him throw his head back in gasps and moans, fingers clutching weakly at Katsuki's hair as he tried desperately to keep watching, to meet those fiery red eyes that stared him down.

And yeah, sometimes it was about letting Izuku take that power, thrusting into him recklessly  and watching him struggle to breathe, to not choke and gag, to take every stroke with eyebrows knitted together in determination, refusing to show any hint of weakness. 

So what if he liked to let Izuku be in charge occasionally? They were partners, after all. That's what you do with a partner.

Right?

"That's it Kacchan, you look so good," Izuku gasped, bringing Katsuki's attention back to the matter at hand in a hurry. "Show me how good you are with your mouth, baby."

Even though he knew it was intentional, Katsuki still found himself falling for the praise every time. Coupled with the little moan in his voice, the breathless way he said it, Katsuki was doomed to fall for Izuku's tricks time after time, and he honestly wasn't sure he cared.

Fingers slipped beneath the tinsel around his throat, dragging him in closer, and Katsuki opened his mouth wide as the hot, thick shaft slid between his lips.

"Oh God," Izuku moaned. "Yes Kacchan, you feel so good!"

Katsuki swallowed hard, amused when it made Izuku shudder a little, trying his best not to blow his load then and there. Not that Katsuki would make it easy for him - he licked and sucked to the best of his ability, humming around the dick and feeling Izuku's grip tighten on his stupid tinsel collar. He swallowed it down greedily, taking him deep, and soon Izuku was pulling him off, frowning at the conceited smirk Katsuki flashed him.

"Pants," he demanded, releasing the tinsel long enough to push Katsuki to the floor, stripping his baggy sweatpants down over his ankles. "Much better."

Katsuki didn't expect it to last long, figured Izuku would be reaching for the lube real quick, but to his surprise he saw another long string of tinsel in the nerd's hand.

"Seriously?" He groaned, when Izuku began winding it around his thigh. "Just fuck me and be done with it."

"But you look so pretty like this," Izuku argued, bending Katsuki's leg to wrap his ankle to his thigh. "You know I like my baby boy to look nice for me."

"I hate Christmas."

"Okay, next year we'll give Hanukkah a try instead."

Katsuki snorted, and Izuku's grin was surprisingly wide as he leaned over, brushing his thumb over a pert little nipple.

"Lots of candles to play with at Hanukkah."

"Fuck."

"You like that idea?" Izuku teased, wrapping his fist around a throbbing cock. "Who would have guessed?"

"Shut up."

"Can't have you finishing too early, though, can we? Wouldn't want Kacchan to blow his load before I even get my dick in his ass."

"Maybe you should hurry up and do it, then."

"I have a better idea."

"Of fucking course you do."

With a much shorter string, gold this time, Izuku reached for him with his shiny spoils. He wound it around the base of Katsuki's dick, despite his whines about it, and secured it nice and firmly behind his balls.

"There!" Izuku said triumphantly, grinning in an almost menacing way. "That should help you keep some self-control!"

"I hate you so much."

"That's not very nice, Kacchan," Izuku pouted, lower lip jutting at him. "Hold still, I still have another leg to do."

"How about you don't and we just fuck?"

"That doesn't sound as fun."

With a low growl, Katsuki let his head fall back to the carpet, staring at the ceiling and trying his best not to think about the scratchy foil wrapped around his dick.

"There!" Izuku declared, stepping back to admire his handiwork. "Perfect!"

"Aren't I always?"

"Even more perfect!" He giggled. "Just let me take a picture, then we can get to the main event."

"No." Katsuki growled, gritting his teeth. "No fucking pictures."

"Not even one?" Izuku pouted again. "You look so pretty."

"Not even one fucking picture of my dick out and wrapped in tinsel," he confirmed stubbornly. "You want that shit to end up in the media?"

"I'll keep it safe!"

"You will not. Have you forgotten that our whole relationship got leaked because of your fucking phone background?"

Izuku swallowed hard, remembering the cute little snapshot of a blushing Katsuki with Izuku's lips pressed to his cheek, taken at the top of Mt. Fuji the first time they'd hiked it together. He hadn't thought twice about making it his background, but then he'd made the mistake of checking his phone in front of a news camera, and the fans picked up on the brief frame of the broadcast in a heartbeat.

"I'm not gonna make naked Kacchan my background!" He protested.

"You're not gonna make naked Kacchan your anything." Katsuki frowned, giving Izuku a stern glare. "Put the damn phone away."

"Mm... I'm pretty sure I'm still gonna make naked Kacchan my bitch."

"Fuck you."

Izuku lifted one foot, pressing it to Katsuki's trussed chest, and with a neat little shove Katsuki fell back, landing against his elbows and linked wrists. Unless he broke the tinsel, there was no way he could move from his position - Izuku really seemed to know what he was doing, and that thought was oddly concerning. All Katsuki could do was watch as Izuku nudged his bound legs wider, giving himself a clear view of Katsuki's beribboned dick and twitching ass. 

"Stay there, Kacchan, I'm gonna go get the lube."

"You're just gonna fuck me on the carpet?" Katsuki asked, jaw clenched. "I'm not fuckin' cleaning up after you."

"I'll get a towel too."

Part of Katsuki had expected that to work. Had expected to at least be moved to the bedroom, whether under his own steam or thrown over Izuku's shoulder - it wouldn't be the first time for either. But no, apparently Izuku was just gonna take him right there on the floor, in front of windows that were admittedly too high up for anyone to look in, the glow of an early winter sunset their only real illumination.

"What if someone knocks?" Katsuki grumbled, as Izuku shoved a towel under his hips and flicked open the lube. 

"You're the king of ignoring our neighbours, Kacchan, I'm sure we'll cope. You'll just have to keep your voice down so no one comes to check on us, won't you?"

"Shut up."

"Make me."

Katsuki glared at him, but Izuku only grinned back, well aware that he'd already won. When Katsuki started making dumb excuses like neighbours the game was already over. 

"Look at me, Kacchan."

Katsuki hadn't even realised his eyes were closed until they were snapping open again, peering up at Izuku as he leaned over Katsuki's tense body, stroking lightly along the strands of tinsel. 

"You okay baby?"

"Fucking fine," he grumbled. "Stop being so caring and shit."

To Katsuki's annoyance, Izuku laughed at him, leaning in close until his hot breath tickled the side of Katsuki's neck. He hummed to himself thoughtfully, tongue darting out to taste him, and when Katsuki squirmed he latched on tighter.

"Oh god," Katsuki hissed, clenching his jaw to keep the moan at bay. "You fucker."

"Oh Kacchan, don't insult me for knowing your kinks," he laughed again, nipping at the little red welt blooming on Katsuki's skin. "You're still being a stubborn little thing, aren't you? Do I need to tighten your collar?"

Katsuki slammed his mouth shut in a hurry - there was no good answer to that. If he said yes, Izuku would do it. If he said no, Izuku would laugh, and then do it anyway. 

"Oh good, you're learning," Izuku grinned, when Katsuki remained silent. "My genius, my Kacchan, you make me so proud when you think about your actions."

"Shut up."

"Is that how we talk to Master?"

"Fuck off."

"You know what to say if you really mean that."

"Fucking obviously I do now get the fuck on with it."

"Maybe Kacchan needs a tinsel gag, too," Izuku mused, looking around at the remnants of their Christmas decorations, half of them boxed away, the others strewn around the room as they waited for a home.

"You want me to stop swearing?" Katsuki asked knowingly, pouting a little. "Whatever."

"Uh-huh. You gonna be a good boy now?"

Katsuki nodded just once, a short, brief movement, and Izuku smiled slightly as he leaned in again, bracing himself with a hand above Katsuki's shoulder.

"Say it, Kacchan. If you don't want me to gag you, tell me you'll be good."

"Ugh."

"So you want the gag?"

"No," Katsuki grumbled. "I'll stop swearing."

"Good boy." 

Izuku kissed a trail along his neck, following the line of the tinsel, and it was all Katsuki could do to keep his mouth shut. He just wanted the damn foreplay to be over with, wanted to feel those strong hands gripping his hips tightly, but no, Izuku had this stupid obsession with moving slowly, taking his time to savour every piece of Katsuki's body first. 

"Aww, look at you," Izuku teased, running a finger along Katsuki's shaft far too lightly. "You're so ready for me, aren't you? Want me to open you up now?"

Katsuki nodded, swallowing hard, and Izuku dragged his touch down slowly, stroking the underside of Katsuki's flushed cock and continuing down past his balls, his warm finger pressing lightly at Katsuki's entrance. He reached for the lube, and Katsuki couldn't help but twitch a little, adjusting himself against his elbows to watch. 

"Someone is feeling needy tonight," Izuku teased. "And you were calling me eager."

"Just f- Just do it. Come on, Deku. You know I hate the foreplay."

"You say that, but little Kacchan seems to disagree."

"It is not little."

"Perfectly adequate sized but smaller than the rest of you Kacchan seems to disagree."

Katsuki snorted, and Izuku smiled wider, drizzling lube into Katsuki's crack. He hissed a little as it trickled down, forming a wet trail that Izuku's hand followed, but when two fingers brushed lightly over his hole he quickly bit back his complaints. 

"There's my good boy," Izuku hummed, rubbing back and forth over the entrance lightly. "Isn't it so much easier to get what we want if we're good?"

When Katsuki didn't answer, Izuku paused, and with a little whine that was frankly adorable, Katsuki nodded.

*Yes, yes, I get it, okay? I'll be good just… Ugh!"

Izuku slipped a finger in mid-sentence, watching Katsuki's back arch, hips thrusting as they tried to find friction. The walls clenched around him, and Izuku grinned, gently stroking with his finger to loosen him up.

"Feels good, doesn't it?" He hummed, eyeing Katsuki's shiny, bound chest as it rose and fell at an impressive pace. "Just need you to relax a little, baby. Let me take care of you."

Katsuki nodded, not trusting himself with words, and thankfully this time Izuku accepted it. Mouth falling open on a gasp, Katsuki dropped his hips back to the ground, and Izuku nodded his approval as he felt the hole loosen around him.

"Kacchan is so tight," he mumbled, more to himself than to Katsuki. "Has it been a while? I guess Kacchan wanted to be on top last time, and on Christmas too, so maybe-"

"Do you have to?" Katsuki choked out. "Yes, it's been a while, just- just do your job."

Izuku paused, and Katsuki groaned again.

"Please, okay?"

"There's my good boy," Izuku grinned. "Sorry Kacchan, I'll focus."

He managed to get another finger in when Katsuki relaxed, stretching him a little wider, and as the muscles began to loosen he stretched his fingers a little wider. 

Katsuki was already leaking precum, always quick to get desperate whenever anything was in his ass, but Izuku wasn't mean enough to point it out.

No, wait, he absolutely was.

"He's so happy!" Izuku grinned, reaching for Katsuki's desperate cock and wrapping a hand around it. "I bet he can cum on just my dick."

"Probably," Katsuki agreed through gritted teeth. "Why don't you try it and find out?"

"It's gonna hurt if I do that, Kacchan! You know that!"

"I don't care."

Izuku hummed in contemplation, watching Katsuki's desperate struggle to stay still beneath him.

"Are you gonna ask nicely?" He asked finally. "Are you gonna say please and thank you like a good boy?"

"Fucking fine."

"Nuh-uh, that's not a good start."

"Ugh. F- Yeah. S-Sorry, okay? Just… God. Please."

"There we go."

Izuku slathered himself in lube in a hurry, making sure to get it everywhere since he knew it was going to be a tight fit all the same, and Katsuki just continued to breathe hard and fast, head thrown back, decorated so prettily with the shiny foil. 

“We should do this more often,” Izuku teased. “I like these noises you’re making.”

“The sex or the stupid tinsel?”

“Yes.”

“Ugh.”

“I love you, Kacchan.”

“If you really loved me your dick would be in me by now.”

“Okay, okay, Mister Impatient over here. Tell me you love me too and I’ll fuck the life out of you.”

“You know I do,” Katsuki complained. “I married your dumb ass, didn’t I?”

“Someone got chatty all of a sudden. I like hearing it, Kacchan! Just tell me how much you love me, and you'll get what you want.”

Izuku leaned in, rubbing the sensitive tip of his cock up and down over Katsuki’s waiting hole, and pressed a tender kiss to a stubbled jaw.

“I love you,” Katsuki admitted, surprisingly sincere considering it was coerced out of him. “You know I love you Deku, Izuku, I’ve always loved you.”

Izuku pushed the head of his dick through the tight opening, and Katsuki's head fell right back, exposing his pale neck.

“I love you,” he repeated breathlessly, chest heaving again as Izuku slowly pushed his way in. “God, Deku, you feel so big.”

“Compliments will get you everywhere, my love,” Izuku snorted. “You’re so tight. I’m not gonna last.”

He picked Katsuki up by the hips, slotting himself in as close as possible, only his bound arms and upper back braced on the carpet, the rest held in Izuku’s strong grip. Without another word he pulled back, thrusting hard into Katsuki’s warmth, and the long, loud moan Katsuki let loose was perhaps the greatest sound he’d ever heard.

Well, the second greatest. After “I do.”

"Again," Katsuki gasped. "Fucking again, Deku."

"Say please, baby."

"Fuuuuuuck. Fucking please. Just don't fucking stop."

"We'll work on the cursing again next time."

Katsuki threw his head back when Izuku thrust into him again, relishing the feel of tight, twisted fingers digging into his hips, sure to leave bruises by morning. He could feel every piece of scratchy tinsel against his skin, tracing the lines of his pecs and abs, and where a few stray pieces brushed over his nipples they felt extra damn sensitive. He could hardly breathe, gasping for air, overwhelmed by every stupid piece of stimulation that wrapped and filled his body, helpless to control it or even direct it, forced to just surrender control and let Izuku take charge, let Izuku seek his own pleasure.

Fuck that made Katsuki throb so hard, knowing he was just being used, like he was nothing but a damn hole for Izuku to ruthlessly fuck into as he felt fit, bound and tied, pushed and pulled, held exactly where Izuku wanted him.

Katsuki saw white, and it took a little breathless chuckle from Izuku above him for him to finally understand, to feel the warm, sticky fluid that trailed across his body. He blinked his eyes open to look, watching Izuku's blissful face, somehow still smiling as with a last hard thrust he filled Katsuki up, semen trickling out around his cock as he slowly rocked his way through the shocks, jamming cum in deeper into Katsuki's ass.

"You okay, Kacchan?" Izuku asked fondly, setting his hips down gently on the floor. "You hear me?"

"I'm good," Katsuki croaked, nodding faintly and grimacing when the tinsel collar scratched at his jaw. "Fucking hell."

"You're such a good boy," Izuku praised, a hint of teasing in his smile. "I love you Kacchan."

"Fuck off."

"I loooove youuuuu."

"Can I take this shitty tinsel off now?"

"But you're so pretty," Izuku pouted. "You should keep it forever."

"Not gonna happen."

"Okay, okay," Izuku giggled, leaning over to touch the strip around his neck. "You want me to do it?"

"Yeah."

"Okay baby, hold still for me."

He carefully unwound Katsuki's neck first, then reached beneath him to snap the strand around his wrists. Katsuki shook his hands out a little, red rings left pressed into his skin, and Izuku took them gently in his own. He planted tender kisses along the marks, grinning when Katsuki blushed, tolerating it for maybe ten seconds before he pulled away stubbornly.

"Get this shit off me so I can shower."

"Nuh uh. We're gonna take a nice hot bubble bath together, screw showers."

"I am not gonna sit in a damn Katsuki-and-Deku sweat-and-cum-soup of a bath. Clean your damn dick before you get in my bathtub."

"You know what I mean!" Izuku pouted, reluctantly removing the shiny tinsel from Katsuki's chest, but placing a much more enthusiastic kiss on each of his little pink nipples. "You must have really liked that, huh?"

"Fuck off! Says who?"

Izuku held up a snapped piece of tinsel with a big bow still tied in it, and his face burned bright red as he remembered the stupid thing, tied around his…

"You broke it with sheer willpower and cum," Izuku giggled. "Kacchan has the most powerful dick ever!"

"Shut the hell up," Katsuki grumbled, looking away to hide his pout. "It's fucking physics, you build up enough pressure and…"

"And the tinsel snaps by force of cum."

"Shut up!"

The legs were last, thighs finally relaxing a little as they fell away, legs sinking to the ground in relief. Freed of his decorations, Katsuki found himself slung over Izuku's shoulder roughly, cringing a little when his tender nipples rubbed against sweaty skin. Izuku didn't seem to notice, too busy lugging Katsuki to the bathroom like a sack of rice or some shit, his muscles barely even tensing with the strain of his weight.

Okay, that was hot.

He was a lot more careful as he set Katsuki down on one of their little plastic stools, reaching for the shower head and making sure it was nice and hot before he turned it on Katsuki. With surprisingly gentle hands, considering all their taut muscle and thick calluses, he soaped away Katsuki's sweat and cum, smiling when red eyes sank closed to enjoy the touch. 

Despite his foul language, Katsuki was surprisingly soft after a good fucking. Lenient and pliable in his hands, the tension seeping out of his limbs as he turned into a little puddle of Katsuki pudding. 

"Stay awake for me baby," Izuku whispered, running conditioner through damp blond spikes. "Just a bit longer."

"Fuck the bath," Katsuki complained, eyes not even twitching toward open when Izuku cleaned his ass out gently. "Just take me to bed."

"You want cuddles?"

Katsuki paused, battling the ever-present struggle within his stubborn mind, but as Izuku rinsed his hair out he managed a tiny nod.

"Okay, just let me finish cleaning us up."

"Mm-hm."

He bundled Katsuki in the softest robe they owned, filled with the stupid warmth of love as he watched Katsuki snuggle in and get cozy, then sped through cleaning himself off so he could take the poor guy to bed. 

"Come on, snuggle bunny," Izuku teased, wrapping Katsuki up in his arms. "I'm gonna cuddle the shit out of you."

"Fuck off," Katsuki answered, more out of habit than anything else. "I don't need your shitty affection."

"You're gonna be a good boy and take it, just like you took my dick so well."

"That's a lot easier to put up with."

Izuku snorted with the way his laugh came out so suddenly, and Katsuki cracked a smile, hiding it quickly in Izuku's broad shoulder. 

"I love you," he admitted, voice barely a whisper. "Should've answered you before."

"I know, Kacchan, it's okay."

"It's not. Shouldn't… Shouldn't reject you or whatever just because I'm stubborn."

"I don't think of it as rejecting me!"

"You know what I mean."

Izuku paused at the bedside, nodding faintly when he gently lay Katsuki down on his preferred side of the sheets.

"Okay. Thank you Kacchan, it means a lot to me that you return the words."

"I know. Now get your ass down here."

Izuku giggled, nodding more confidently this time as he rounded the mattress, crawling up to Katsuki's back and pulling him in close. He tucked the slim little body into his chest and curled around it happily, savouring the way Katsuki seemed to fit so perfectly into him, like one of Yaoyorozu's little collection of nesting dolls. 

"Yeah, yeah, we're fuckin' made for each other, now quit mumbling in my ear."

"Sorry!"

Katsuki huffed a little sigh, but snuggled in tighter all the same, dragging Izuku's arms around him and holding them in place firmly. He blushed bright red as he did it, but Izuku didn't say a word, just smiled into his hair and held him obediently.

"You're the prettiest husband in the whole wide world," Izuku whispered. "With or without tinsel."

"Thank fucking Christ, without."
