Waking up is usually either a very irritable affair- mornings when his consciousness is ripped out of dreams by his alarm, or something to be treasured and thoroughly enjoyed for the simple pleasures it can give. The mornings when he can sleep in, waking up naturally with his husband curled into his side, face resting atop his chest as if still listening for his heartbeat even in his sleep, one arm draped over his stomach where their fingers usually lay entwined.
Katsuki loved those mornings. He’d lay there for hours if he could get away with it, just taking in the sight of that beautiful face, so soft and clear of the worries and stressors that came with the life of being a hero. Sleep wiped away the stress lines, the furrowed brows, concerned frowns, all of it, leaving in their place a much younger face. Truly, when Izuku was unburdened, his husband hardly looked like he’d been more than a day out of high school.
This weekend was going to be one where he’d be able to enjoy his mornings. They’d gotten the rare weekend completely off, barring disasters where they specifically were needed. Katsuki was fully intending on taking advantage of his days off. Lazy mornings in bed with Izuku before he coaxes his husband out of the comfort of the bed with the lure of some god awful carb-y breakfast that wrecks their usual meal plan.
He knew Izu wanted to go catch a movie Saturday evening for date night, so he’d already secured tickets, and made a reservation at their favorite restaurant afterwards. Neither of them made any plans for Sunday, usually it was used for a relaxation and self care day for the pair of them.
All of this to say, usually his mornings began one of two ways. Alarms or a slow, natural return to consciousness.
This was not one of those mornings.
The first thing Katsuki becomes aware of is a gentle rocking motion. Confusion flickers haphazardly through his brain, like it’s not sure if it should actually be cataloging this in the first place. The feeling is so slight that Katsuki could almost ignore it and slip back under the waves of sleep.
Were it not for the next feeling that tingles up his spine. Pleasure curls like smoke around his spine, and spreads out across his body. A new wave is sent out in time with the rocking motion, but he still is too sleep-addled to connect the dots. All he knows is the embrace of the sensations that are beginning to overwhelm him. A throaty groan falls from his lips as he feels himself being stretched, the feeling dragging him a little further into consciousness, and he arches his back.
It’s when he feels more pressure added, pulling a whine out of him, that he tries to move his arms. And realizes he can’t. Between the added pressure, and the discovery of the restraints, Katsuki finally slips out of the clutches of the hazy half sleep state he’d been in.
Carmine eyes snap open as fingers continue to curl into him, and Katsuki can’t stop a shuddering gasp from slipping out as he looks down his body and finds Izuku’s gaze already locked on him.
“Good morning Kacchan. Enjoying yourself?” His husband’s voice was soft in the quiet of the room, but the heat it held had Katsuki dropping his head back against his pillow as he bit his lip. Fucking hell.
His gaze slid up to the headboard, and he saw his wrists were tied to the posts, and were snug enough that he couldn’t do a damn thing about it.
Sneaky little bastard. That absolutely was not a proud smile curling his lips up at all.
Fingers curling into the bundle of nerves and rubbing intently drew his attention off the ropes around his wrists as he bit out a loud cuss and bucked his hips away from the sudden intense feeling.
“Mmm Kacchan, I asked you a question. ‘s not nice to ignore me, you know.” Viridian eyes pinned him in place far more effectively than the ropes could at the moment. Fuck, those eyes were filled with mischief, desire, and something that told Katsuki if he fucked around, he was gonna find out the rough way. Kami, if that didn’t have heat pooling in his belly, and his cock, which was thus far very rudely ignored, leaking pre in anticipation.
Licking his lips, Katsuki rolled his hips and pointedly looked down at his cock. “I should think it’s pretty clear I’m enjoying myself, nerd. What about you, when are you going to enjoy me, hah?” If he didn’t get Izuku pressing into him soon, he was going to blow a hole in the wall. Through all of this, his husband was still managing to pump his thick fingers in and out of his lubed hole without so much as touching himself even though Katsuki could see the proof of his arousal hanging so tantalizingly between his legs.
Greedy fucker needed to put that where it rightfully belonged.
“I will, don’t you worry baby. Just as soon as I hear you beg for it.” and holy fuck, was the smile he flashed Katsuki with that statement downright sinful. It very nearly undid the blonde right then and there, his cock twitching uselessly against his stomach where a small pool was quickly forming.
However, they have not been through two and a half decades of competitiveness with each other for that to not come into play in the bedroom as well. Katsuki was not about to just lay down and take it. Well… figuratively speaking at least. Izuku was gonna have to wrest this victory from him.
“Good luck with that, Freckles. I don’t just beg . You’ll be prying it out of me.” The adrenaline spike that surged through his veins lit a defiant fire in his eyes as he grinned up at his husband.
“Wouldn’t have it any other way, Kacchan.” With that, Izuku licked over a canine before dipping down and peppering sharp bites over his pecs before soothing them with featherlight kisses or kitten licks. It wasn’t long before he turned his attention to a dusky nipple, drawing it between his lips and sucking gently.
Katsuki arches his back, his eyes locked on his husband. Fuck, it’s damn near overwhelming. He feels his free hand slide up and down his side languidly before settling at his hip and pressing his thumb in to massage. Katsuki is being blitzed on multiple fronts and he can’t stop the moan that shudders out of him.
Izuku releases his nipple with a wet - pop! - sound, and he can’t help the thought of how fucking hot Izuku looks with his spit-slicked, plumped lips and half lidded eyes as he glances up at him from under his eyelashes.
Izuku’s fingers are purposely kept from tipping the blonde over the edge, but continuously keep him in a dizzyingly aroused state. Every so often, Izuku spreads his fingers, twists his wrist, or glides against his prostate. It doesn’t give him even a moment to catch his breath or get ahold of himself.
“ Fuck … Fuck! Izu …” Katsuki murmurs, gritting his teeth as he throws his head back. He tries hooking his calf behind Izuku and forcing the bastard to break first, but it is an effort in futility. His husband doesn’t budge even an inch, and all he gets for his efforts is a throaty chuckle.
“Aw c’mon Kacchan, you can do better than that. Or… you can just give me what I want, sweetheart. It’s so easy, all you have to do is say ‘please’.” Izuku leans into him as he speaks, whispering into the shell of his ear, and practically sighs out the last word. It sends shivers running down Katsuki’s body and if he weren’t tied down right now, he’d be pinning Izuku and fucking him instead. Goddamned tease.
Apparently, Izuku sees that in his eyes when he pulls back, because he gives Katsuki a wicked smile. “Hmm, I thought perhaps you were close, but it would seem I was mistaken. More… aggressive persuasion might make you see the light, no?”
Katsuki only has a moment to feel his heart stutter for half a second, wondering what his husband has in mind, when suddenly blackwhip is shooting out and wrapping snugly- very extremely snugly around the base of his cock. Oh no. Shit.
“Izu, don’t you fucking even think about it you little shi-!” His voice cuts off with a strangled moan as Izuku is sliding another finger home, stretching him quickly before he starts thrusting his fingers in with force, just the way he loves it. His cock is twitching and the thought of Izuku’s hand or mouth on it right now, he wouldn’t last longer than a few precious thrusts.
He needs to cum.
The pressure is building, and Katsuki can do nothing to relieve it. Well, almost nothing. All he has to do is beg. And fuck if that isn’t looking more and more tantalizing by the second. His skin is sweat slicked, and his muscles are trembling as he fights to find any measure of relief. There is none.
A gasp is torn from his mouth as Izuku thrusts particularly hard, and Katsuki can feel himself fraying at the edges. The head of his cock keeps bobbing in the puddle of pre, and the sensation is the only stimulation it’s getting and he writhes.
And then Izuku is dipping down and nosing at his thigh. Katsuki only barely manages to focus long enough to glance down his body to where Izuku has nestled himself. He looks like the cat that caught the canary. Perhaps he is. He watches as his husband licks a stripe up his inner thigh to his hip. Fuck, he’s so close. He’s right there. Katsuki can’t help the soft whine as he rolls his hips up.
For his troubles, Izuku flicks his tongue out and swipes a bead of pre-come off of the head for himself, before kissing it. It was covered enough in pre that when he pulled away, a thin strand connected him to Katsuki’s cock. The sight made him groan. Izuku’s eyes crinkle as he smiles up at Katsuki before he sinks down, encasing Katsuki’s cock with his mouth.
“Fuck!” The hand that had been lazily rubbing his hip before now pinned him to the bed as he tried desperately to thrust up. He could feel his tongue swirling around him, before Izuku’s cheeks hollowed out and he began bobbing his head slowly. Katsuki could feel his balls drawing up, but it didn’t matter.
Izuku, through blackwhip, owned his ability to orgasm.
Katsuki shattered.
“ Please. ” a ragged gasp was what ended up being ripped from his mouth. Izuku froze for a moment, before slowly drawing up and off of his cock, making Katsuki whimper at the loss.
“What was that?” Izuku cocked his head to the side, and Katsuki couldn’t even scrape enough fucks to give to be annoyed that he was gonna make him repeat it. He was desperate.
“Please. Fucking please Izu! I can’t fucking do this anymore, I need you, please! Fuck!” He’s barely holding on at this point, and it’s only when he realizes that his vision is blurred slightly that he feels the tears beading in the corners of his eyes and wetting his eyelashes.
He doesn’t hear the punched out groan that slips from Izuku’s throat, hardly sees the victorious and hungry gaze he pins him with, but he does feel fingers withdrawing, and a sudden emptiness that bowls him over. No thoughts processing, he snarls desperately and hooks his ankles behind Izuku.
“Don’t worry Kacchan, you begged so very prettily, I couldn’t possibly turn you down after that.” Izuku crawls back up, slotting his hips flush to Katsuki’s as he dips down and kisses the blonde, who surges up and clashes with his husband, immediately pressing for entrance.
Izuku of course, grants it, and Katsuki licks up into his mouth, meeting his tongue with his own in a dance. All the while, Izuku is lining himself up and starts to press in slowly. Katsuki desperately wishes for the use of his hands right now, fuck how he’d love to rake lines down Izuku’s back.
Actually, yea, he’s getting his hands back.
Nipping harshly at Izuku’s lip he pulls back, panting, eyes fully dilated as he tugs at the ropes. “Izu, Freckles.. Baby give my hands back please. I need to mark that back of yours up.”
Izuku, having only really pushed the head in, froze at his words, and Katsuki gets to watch how his words physically affect him. A full body shiver runs down his husband's body as his mouth drops and eyes go hazy and half lidded. He looks damn near drugged.
“Y-yea, alright, Kacchan. Since you said please.” His wrists are undone in record time, and before he can even do anything with the freedom, Izuku is lifting one of Katsuki’s legs, throwing it over his shoulder and then burying himself to the hilt.
The blonde lets loose a cuss as Izuku stretches him more than even his fingers had been. His hands fly to Izuku’s back, blunt nails digging in. His cock is fucking throbbing against his stomach, and while he’d absolutely come undone if he were unleashed, it’s a mere passing thought at the moment. He knows what’s about to happen, and why the fuck isn’t it happening already?
“I love you, Katsuki.” Izuku nuzzles into his neck before biting down at the junction between his neck and shoulder, and Katsuki keens, rolling his hips.
That seemed to be what snapped the final thread of Izuku’s patience. His husband set a punishing pace, pausing only at one point long enough to drag Katsuki’s other leg up and then pinning his legs up by his shoulders as he fucked him. Kami, it was a good thing they had decided to get into yoga. Still, the burn in the back of his thighs feels absolutely delicious and leaves him practically mewling.
Katsuki made good on his desire too, with his hands free, his claws were pretty much permanently embedded in and sliding down Izuku’s back. Once Izuku changed his angle and started targeting Katsuki’s prostate, it was all he could do to just hang on while he cried out.
The entire time, since Katsuki had broken down and begged, his cock remained untouched. It bounced between them as Izuku thrust into Katsuki, and once he’d been put into the mating press, if he was lucky Izuku would pin it when he’d bend down to kiss Katsuki, who absolutely took advantage and ravaged Izuku’s lips. He’s still not sure he was the winner in that situation, but he didn’t care. But there was no friction, and blackwhip was still around him.
Why was blackwhip still around him?!
“I-Izu! Blackwhip?” Fuck, he couldn’t keep up with the assault on his body like this. Izuku was nipping at his neck, and purposely gliding along his prostate like a bow across the strings. And kami if that wasn’t an accurate depiction too, from the way his body was fucking thrumming. He felt like he was going to vibrate out of his own skin.
“Mmmm. Mhmm. You know what you need to do for blackwhip to come off. As soon as you’re ready Kacchan.” The words were so simple and gave Katsuki the solution he needed. He was beyond too far gone to even think about fighting anymore.
“Please Izuku… Please let me co~ oh! ” Blackwhip snapped free the moment Izuku smiled, Katsuki could tell. However, he was immediately overwhelmed by Izuku pressing straight into his prostate, as well as apparently having stealthily slid a hand down and wrapped around his cock and sliding down his length. There was no stopping the embarrassingly loud moan that was manhandled out of him.
“Iz-uuu.. fuck!”
His muscles tensed, and he clenched down tight around Izuku as his orgasm rushed over him. Body trembling, he could feel his release paint from his stomach up to his chest, and his head fell back, panting heavily.
Izuku is right there, pressing a gentle kiss to his temple. “Good boy, Kacchan.”
It takes him a couple seconds, and he admits he preens in the glow of being called Izuku’s good boy. But he’s able to calm his racing heart enough to gasp out “What… are you… waiting for? Better not be holding back for my sake, nerd.”
And sure, he’s definitely a glutton for punishment, when he’s already so fucking sensitive, baiting Izuku like that. But what’s life without a little fun right?
“Wouldn’t dream of it, Kacchan.” he watches a smirk slide over his face before Izuku pulls out long enough to grab him by the hips, and next thing Katsuki knows, he’s been flipped over and placed on his knees with a palm gently pressing between his shoulder blades until his chest and cheek are flush to the bed.
He doesn’t even have a moment to crack his eye to glance back at his husband before he’s sliding back in, the new angle sharper and making his eyes flutter from the intensity.
“ O-ooh Kacchan… F-fuck I always forget how different the a-angle is.” Izuku’s voice is finally betraying the strain. He always hides it until after Katsuki finishes when he’s topping, though there have been a handful of times that Katsuki managed to break him. He can’t say much though, he does the same damn thing.
Once competitors, always competitors, it would seem.
“C’mon baby, it’s your turn.” Katsuki murmurs softly to Izuku and grinds his ass flat against Izuku’s hips. It causes him to let out a strangled growl, which prompts Izuku to grab his waist and start thrusting. His walls are so fucking sensitive, and each glide feels like magic but also just on the edge of too much, and it’s such a delicate line but holy fuck is it one that he love to walk.
He can tell Izuku is getting close, he can hear the soft, needy whimpers, and slowly the rhythm is being lost. He twists his arm behind his back and holds his hand out, offering it to his husband. Izuku grips his hand like it’s an anchor keeping him from getting lost at sea. His hips are slamming into Katsuki, and it’s all Katsuki can do to just stay rooted in place. He can feel pressure building again, but he’s not sure he has it in him to go again. Fuck.
Their trembling breaths overlap, impossible to tell one from the other, but it’s now Izuku who’s becoming the more vocal of the two. Desperate, breathy pleas, too broken for Katsuki to actually make out, keep falling from Izuku’s mouth and he’s now curled over Katsuki’s back, sliding his free arm around his waist locking them together.
Katsuki rocks his hips back, grinding languidly when he feels Izuku’s hips stutter and then he’s pushing in deep one last time before Katsuki feels a jet of warmth flood him to the overture of a shaky gasp. “ Kac-Kacchan~! ”
And it’s with that that his walls are fluttering around Izuku, and before he knows it he’s pitching over the edge again, coming with a muffled whine as he turns his face into the bed, his body jerking and twitching with spasms.
Katsuki feels wrung out, literally only not in a crumpled heap by the grace of Izuku’s arms. Which, how the hell he hasn’t collapsed yet, would be beyond him, if he didn’t know that his husband had fucking ridiculous stamina.
It was a boon though, because it meant that Katsuki got to be a bit of a princess afterwards, and really did collapse into Izuku’s arms, who simply smiled, kissed him and helped clean him up.
Once both of them were cleaned up and back in bed, tangled up in each other’s limbs, Katsuki grabbed Izuku’s chin and forced his gaze up. Serene viridian eyes met his, and he pressed his forehead to Izuku’s before softly whispering “I love you too, Izuku.”
