Izuku was not panicking.
Nope.
He was definitely not in a tail spin of all consuming worry that had him riding out through the forest towards the kingdom where his husband was currently supposed to be. No, he was not worried for his husband who was in enemy territory gathering intel. He was not worried about his husband being in enemy territory alone. And he most certainly wasn’t worried about his husband holding his own if he were to be caught in said enemy territory.
No, that wouldn’t cause him to worry.
But what does have him in an all consuming tailspin of panic is the fact that close to 5 hours ago, Izuku could no longer feel Kacchan down their bond. Like their connection had completely been severed. No remnants of warm burning caramel. No underlying tone of love filling his veins. No blazing heat warming his bones.
No Kacchan.
And that had never happened before. Never. Not once since they bonded when they were little. Even during their younger years when their relationship had been the worst… Izuku could always feel Kacchan. Right there next to his heart. But now? Absolute silence.
Izuku chokes back tears as he paces the secluded area of forest surrounding one of the villages of the Kingdom their Clan had been trying to gather information on. He’d already walked through the entire village with a disguise spell hiding his most distinctive features - he knew Kacchan would recognize him immediately though, but he did not find one trace of his husband. And no word from the villagers either of seeing a man matching Kacchan’s disguised description.
Izuku had made his way back into the forest and started scouring the area. What he did find was Kacchan’s horse tied up a mile in and his saddle bag at the base of the tree. He’d dropped the disguise spell and began putting up protective wards alongside the smaller ones his husband had already placed.
Izuku didn’t want to believe that Kacchan had been attacked from such a well hidden area - they were nowhere near a pathway or general hunting area. But he wasn’t sure what other explanation there could be. Kacchan was just… gone. There was no evidence of a fight; no evidence other people had showed up in this same spot; no tracks leading towards Kacchan and no tracks leading away from Kacchan. Like he had poofed out of existence.
Izuku shakes his head, trying to physically clear his anxiety. He needed a plan. Needed a way to find out what magic may have been used to transport Kacchan to a different place. Izuku needed a way to speak with their Kingdom’s mage and find out what they could do… without actually letting them in on the fact they needed intel on their Kingdom in the first place.
Izuku growled to himself in frustration, the finger at his lip tapping as he tried to come up with plan after plan to get Kacchan out without getting them both killed and leaving their children parentless, when suddenly a bright white light burst from behind him, casting shadows against the trees. Izuku turned abruptly, ready with his defensive magic flowing across his body - the bright green lightning crackling against his skin, only for it to peter out as his eyes land on the person in the glowing iridescent bright light.
“Kacchan.” He breathed - eyes locking immediately with wonderfully gorgeous vermillion.
“Izuku.” Kacchan’s voice cuts through him like a knife and just as quickly as their bond had silenced, it snaps back with such ferocity Izuku feels his chest ache at the explosion of love and home emitting from his husband standing only a few feet away. “Izuku.” Kacchan repeats, like he’d missed the way it felt in his mouth, a smirk pulling at the corner of his lips, “Oh, you’re definitely my Izuku.”
Izuku cries openly and rushes towards his husband. Kacchan’s arms spread immediately, opened wide to catch him as he wraps his entire form around his body. Well known roughed, calloused, yet warm and gentle, hands come to rest against Izuku’s back, digging into his shirt and pressing him fully into his husband's chest.
“Where the hell did you go?” Izuku grits out where his face now rests in Kacchan’s neck. He breathes in deep, taking a chance to let the warm caramel and maple scent overwhelm him. Even though it had been a few hours, not having their bond - not having that reassurance he was alive - made it feel as though his Kacchan had been gone an eternity. “What the hell happened to you? Our bond was silenced, Kacchan. How did - “
A chuckle fell warm and fuzzy from his husband and Izuku felt a spike of calm chase his fears and worry away. Felt the ease of comfort and peace yell at him down their bond - of something happy spreading between the cracks of anxiety that had formed. “I’m not sure how much you’ll believe once I tell you.”
What? Izuku pulls back from his buried position in Kacchan’s neck and narrows his eyes at him apprehensively, “What is that supposed to mean?”
Instead of an answer Izuku is met with lips pressed against his own and his husbands tongue licking into his mouth. Izuku kisses back on instinct; he loves the way his husband kisses him, of the way he makes him feel like he’s well and truly loved each and every time. Izuku comes back to his senses quickly though and tries to pull his head away.
“Kachcan, wait - ”
But Kacchan only chases after Izuku’s lips once more. Pulling him into his loving embrace which has started to press in from all sides of their bond. Izuku moves his mouth against Kacchan’s, tasting a familiar spice on his tongue he can’t identify, fingers going into the strands of blonde at the base of his skull.
“Wait - ” He tries again, separating their mouths with a pop and a trail of spit. Kacchan however just moves to press open mouth kisses against his jaw and neck, nibbling at the skin there, “You need -ah, you need to -fuck. Kacchan, please, I need you to focus - ”
“I am focusing,” Kacchan breathes against Izuku’s neck, licking at the bite mark he made near Izuku’s ear. Izuku sighs at the cool air there, he knows Kacchan knows that’s one of his more sensitive spots. But doesn’t he realize that they have a more pressing matter? Their bond had been silenced and Kacchan himself had been missing. He needed to know what Kacchan knew, especially if it was such a whirlwind tale that Kacchan believed Izuku wouldn’t believe half of it.
“You’re thinking too loud.” Kacchan grumbled and nosed his way up Izuku’s throat, pressing kisses down his jaw line before conquering his lips again. This time at a much softer pace.
“Because you,” Izuku tries to get out between kisses, “haven’t told me why the bond silenced.”
Kacchan pulls back slowly and meets Izuku’s eyes. A heat so divine shoots down the bond that it has Izuku shuddering, limbs wrapping themselves even tighter around his husband. Izuku knows those eyes; knows what kind of thoughts his husband is thinking - and mixed in between the love and calm and home is desire so thick Izuku could drown.
“You let me make out with you till I’m satisfied and then I’ll tell you what happened. It’s nothing bad; it’s almost quite good really. But if I don’t make out with you right this second I fear I can not be held accountable for taking you immediately once we enter our village.”
Izuku can feel the blush heat up his face at the words, but he also knows how true they can be. Having gotten into some similar trouble when they were younger and almost getting caught against the backside of one of the village’s shops.
“Fine.” Izuku concedes, “But,” he reaches around to cup the left side of his husband's cheek, “I’m dropping the disguise.”
He’s met with his husband's trademark devil grin and immediately latches his mouth back onto Izuku’s. Taking him in with tongue and teeth. Izuku laughs into the kiss and uses the hand not cupping his husband's cheek to make the intricate movement to cancel the disguise spell. He’s at ease when he can feel the rough bumpy texture of Kacchan’s scar against his palm.
Tension leaves his shoulders as Kacchan devours him in the forest. Their bond open and flowing as before. Izuku thinks they deserve to make out in the forest for a bit… just to make sure everything’s in working order.
* * *
“So you’re saying there were 4 other Kacchans and the one thing that tied you all together - the one thing that made it possible for you to come back home - was your love for me?”
Izuku can barely get the words out. They’ve been travelling for quite some time on their horses back to their home. And Izuku’s been listening to Kacchan tell the tale of his adventure to another realm. The story has Izuku’s head spinning but it’s not like he hadn’t had such deep thoughts before. He’d wondered once when he was studying magic about other beings out beyond their world - amongst the stars. He had wondered what else could exist besides them. And apparently some magic ability - “a quirk”, Kacchan had reminded him - from another Universe, brought his Kacchan and three others to a specific Universe’s Kacchan. One where they were teenagers again and had yet told the other how they truly felt.
For an odd reason, Izuku could understand this, could see how this could occur. He found it truly fascinating really. But he was struggling with the common theme connecting each of the Kacchans.
“Yes, Deku.” Kacchan emphasizes once more.
“Well!” Deku waves a hand in the air as if that emphasizes his point. It’s not like he hadn’t dreamed about that before. About him and Kacchan being so closely bonded that their love would transcend the world they know. A dream really, to believe that they would always find each other - would always love each other. It’s a tale that he’s read in some books Uraraka has stashed in her small library. But reality? It doesn’t seem possible.
“Oh okay, fine,” Kacchan huffs, his horse snorting as well and it makes Izuku chuckle at the similar energies those two give off. “Oh don’t even start,” Izuku feels what is similar to a flick to the forehead through their bond, but the underlying sense of happiness and affection only make his smile widen further. “But seriously, Deku, you can believe that I travelled into a different universe. That there were multiple versions of us that existed. One where you apparently become like the very things we are currently trying to fight against. One where you died protecting me, even -”
Izuku flinches at that one. He’d been so saddened to hear about that Universe’s Kacchan - Katsuki, Kacchan had called him. To have fallen in love with his Izuku - to have realized his feelings for his Izuku - but too late to do anything about them? To have watched someone so important to him die? Izuku knows just enough about that to make him feel a great sadness for Katsuki. He wishes that he could do something to help him… but what could he do being in another realm? Izuku would take the pain away of all Kacchan’s if he could.
“ - and yet.” Kacchan continues on despite Izuku’s darker thoughts clouding the bond, “you still can’t wrap your head around the idea that we all love you. Amazing. Absolutely amazing, Deku. How can you be so smart and stupid at the same time?”
“Hey!” Izuku cries, but knows his husband does not mean for it to be rude. But Izuku sends a spark of magic toward him anyway - zinging a pinch of electricity into his leg.
“Ow! Fuck you, nerd.” Kacchan yanks the reins to steer his horse closer to Izuku and lifts his leg to push the toe of his boot into his side. Izuku chuckles and shakes his head at his husband's antics. Not that he didn’t know it was coming, but the familiar back and forth has cleared some of his darker thoughts away.
They ride in silence for a few moments. Izuku’s mind going back to the other Kacchan’s and Izuku’s. He wanted them all to be happy. Just how he was happy. And he wondered…
“Kacchan,” Izuku called to him, keeping his eyes forward, locked on the setting sun before them.
“Yeah?”
“Do you think the one version of you, the one with his Izuku there with him,” He emphasized, “Do you think they actually confessed?”
Kacchan snorts loudly to his left and Izuku turns his eyes to him, narrowing them in interest, “They better have with that Speak from the Heart spell I fucking cast before I left.”
Izuku can feel his mouth drop, “Kacchan! No!”
“Yup,” He popped the ‘p’ at the end, turning to smile brightly at Izuku. Izuku can say he’ll always love this version of his husband - the one relaxed and bright and happy. Shining like a beacon in the setting sun.
A laugh bubbles up from Izuku’s chest and he shakes his head at his husband in disbelief, “Oh, those poor boys.”
“Yeah,” Kacchan nods, “They’re probably fucking right now.”
“Kacchan!” Izuku sends another zap of energy to his husband's leg, “They are not! Let them have their moment!”
Kacchan rolls his eyes, then settles them onto Izuku, deep and heavy and Izuku is reminded of their first time - quietly tucked away in the forest, laid out on their joined capes, the same deep vermillion looking into him - into his soul. The same eyes lock with his now and Izuku wants nothing more than to take his husband into his arms and cherish him in every way he knows how.
“If they’re anything like us,” Kacchan’s voice dropped low and a shudder runs up Izuku’s spine, “And given that they are us, the possibility is pretty fucking high that they confessed. Made out. Then had sex within the hour.”
Well… it’s not like his husband is wrong. And with those eyes boring into his own Izuku can only admit defeat. “Well, you didn’t have to be so crass about them.”
Kacchan’s grin turns devilish, “Hah! Those two had so much fucking tension I could have cut it with my sword.”
Maybe the two were more like him and his Kacchan than Izuku would have liked to admit. He hopes that those two versions of themselves are okay. That the spell helped them find the space needed with their thoughts - that the thoughts shared would be a help rather than a hindrance.
“Hey,” His husband calls again, and Izuku realizes he’d been staring off into space while looking at him.
“Yeah?”
The devilish grin seems to broaden if possible, a sharp canine easily seen over his husband's lip, “Were getting pretty close. Let’s race. GO!”
Before Izuku can get a word in, Kacchan uses his heels to signal his horse to increase his gait, and they’re both off, racing across the field of flowers they’d been traveling through to cut their travel time down.
“Fuck you, Kacchan!” Izuku calls and receives a loud cackle back at him on the waves of the wind. He pushes his own stallion into gear and soon they’re racing to catch up. The bond between them grows just a little brighter and Izuku laughs loud and joyously at the feeling.
They make it back to their village, just as the sun sets an orange glow throughout their streets. Izuku can’t keep the smile from his face at having beat his husband in their racing contest. He can see the pout, turning his husbands lips downward but the bond lets him know his husband is just as happy about Izuku winning as he would have been if he had won instead.
Their people greet them as they ride through, making their way towards their home on a larger hill, a bit further out of the cluster of homes. There they find Kirishima standing at their door, face morphed into one of great worry - his wings flapping lightly as they do when he’s nervous.
“Izuku!” He calls when they make their stop, heading around to the barn to get their horses settled. “Kats!”
“Shitty hair.”
“Hi, Eijirou,” Izuku smiles and waves, getting off his horse and leading her into their small stabled area alongside Kacchan. “Thank you for taking over while I was gone.”
“It’s no problem, man.” Eijirou came up between them, wings still twitching, “I’m just glad everything ended up being okay! You’re okay right, Blasty?”
“Right as a dragonling, Ei.” Kacchan speaks up, but doesn’t elaborate. Izuku reaches down their bond in confusion, because Ei is their closest friend - is Kacchan’s official 2nd in command. If there would be anyone to tell about what happened to him, it would be Eijirou. Kacchan sends him back the feeling of tiredness and slight hesitancy and a need to be home.
Izuku understands immediately and does his best to reassure Ei that everything is okay. That Kacchan was fine, but that they’d need to find another day to do an information extraction. Kirishima takes it all in stride - happy that Kacchan is okay. Eijiro leaves them both with a giant hug and with such great understanding they both agree to get him something nice for dealing with them.
Once their horses are settled, they make their way inside their home to the sight of Kacchan’s dad reading a story to their children. A calm sight of them all curled up on some furs in front of their fireplace. Izuku always marvels at the fact Masaru can always get both Eri and Kota to calmly sit for the same story.
Of course the careful calm Masaru has cultivated is instantly gone as soon as they walk into their home. Three faces turn to greet them and the small ones light up so bright, Izuku could swear they’d block out the sun.
“Daddy!”
“Papa!”
Both their children shout and rush immediately to them. Kota jumping up into his arms while Eri cheers when Kacchan lifts her up and onto his hip.
“You’re home!” Eri smiles brightly.
Kota on the other hand pouts and pulls back from his hug around Izuku to fold his arms across his chest, “You’re late! And grandpa said you had to leave and go get daddy, papa. What was that about?”
Izuku tries not to let the slight panic show on his face. He loves his children, he really does, but the way they can just cut straight to an issue sometimes scares him. Sometimes they’re too much like him and Kacchan. “Daddy just needed a little help with his mission.”
“But Daddy can do stuff by himself! He told me so.” Kota points a finger in Kacchan’s direction accusingly. Kacchan’s eyes go wide and Izuku tries his best to hide the smile pulling at his lips. It wouldn’t do well to laugh at his husband's misfortune at the moment.
“No.” Eri jumps to her dads defense, “Daddy always lets Papa help him.”
“That’s right, baby.” Izuku nods at her, and lowers Kota’s pointed finger back down to his little body. “And Kota baby, even if it’s Daddy it’s not nice to point like that at someone.”
“Oh,” he looks down at his feet, then back up to Kacchan, “Sorry, daddy.”
Kacchan opens his other arm up and Izuku passes Kota over to him, “Apology accepted.” and Izuku does smile this time at the pleased look over Kota’s features. His Kacchan has come so far since they were that small.
Before Izuku can let memory lane take hold in his mind, he turns to Masaru to thank him for taking care of the children.
“It’s not a problem, Izuku.” Masaru smiles kindly towards him, “I love spending as much time with them as I can.”
“You’re always welcome here, as you know.”
“I do,” Masaru nods, “but I thank you for the reminder.” Behind them Izuku can hear his children begin to loudly tell their daddy about their day.
“Have they eaten?” Izuku asks.
“Yes, I had some leftover roasted chicken and prepared some vegetables from the garden for them. They should be ready for bed soon.”
Izuku nods in his thanks. “Would you like to put them to bed? They do love your bedtime stories.”
Masaru shook his head, still smiling kindly down at Izuku, “No, no. They haven’t seen you both for most of the day. Take the time with them. They missed you while you were gone.”
“Tomorrow night then,” Izuku tries to compromise. Typically his mother would have come, but as her and Izuku’s mentor/step-father were traveling at the moment, Eri and Kota would not have a grandparent to come and read them to sleep on their typical day.
“Tomorrow,” Masaru agrees easily, “I shall take my leave, now. It is good to see you’re both okay. I’m glad my son has you to take care of him.”
“I’m happy I have him to watch out for me too.” Izuku agrees, “Have a good evening, Masaru.”
Masaru leans in to give Izuku a small hug, before heading towards the door, “Good-bye dragonlings!” He calls out to them, “Good-bye, son.”
“Bye grandpa!” Both of his kids stop their story telling to yell out.
Kacchan however freezes abruptly and drops the kids down to their feet, stepping quickly towards his father, “Dad, can I talk to you a second?”
Both Masaru and Izuku freeze. Izuku can feel a vague sadness through their bond and he wonders what could be so urgent that Kacchan would call his father ‘dad’ instead of ‘old man’.
“Of course, Katsuki. Come outside with me, then.” He gestures to their front door and makes his way out.
Kacchan turns to give Izuku a quick glance, and he finds sorrow and grief lining his features. Izuku reaches up to cup his husband's cheek, then presses a light kiss to the other, “Take your time. I’ll get the kids settled.”
When he pulls away, Izuku is glad to see some light still glinting there. “I’ll be only a moment.” Then he steps out the door to speak with his father.
Izuku turns to his children, both looking at him with bright smiles and they immediately begin telling him about their day. Izuku listens with rapt attention as he ushers them up the stairs and into the loft of their room. He’s gotten them calmed down and into bed - taking time to tell them a short tale of an amazing warrior named All Might saving two children from a terrifying creature. He kisses them both on their foreheads, but leaves the candle on for Kacchan to blow out when he comes up to say good-night.
Izuku heads back down the stairs and works to put out the fire in the hearth. With it being summer, there was no need for the extra heat in the night. But when Kacchan is still not back from speaking with his father, Izuku begins to put away their packs.
He’s in their room when he hears the front door finally open and close. Izuku doesn’t call out to his husband, knowing he’ll meet him in their room after telling their children good-night. Izuku can feel the calm blanketing Kacchan through their bond. Something settled in him that Izuku hadn’t realized had been unsettled. He wonders what they had discussed. But he knows better than to go digging. Knows Kacchan will come to him when he feels ready and not before.
Warm arms wrap around Izuku’s waist and a face buried in his neck as he puts the last of their furs into the cupboard against their far wall.
“Hello, Kacchan.” Izuku greets, reaching back with one hand to thread fingers through his husband's blonde spiky locks. A series of slow kisses are pressed into his neck. Izuku tilts his head to the side slightly to give his husband more room and breathes in a deep sigh when Kacchan does as expected and begins to leave bruising marks against his skin.
“I love you.” Kacchan breathes out eventually, face still buried into Izuku’s neck. “So much, do you know that, Izuku.”
Izuku hums and nods, “I do. And I love you, Kacchan.” They stay firmly in place, breathing together in the their small room, in their warm home, where their children sleep above them and they can be their most authentic selves.
“When - ” Kacchan starts, but cuts himself off. “When I was in that other realm…” He peters off and doesn’t continue.
Izuku, knowing what his husband needed, turns around in his arms and wraps him tightly in a hug. Running his hands up and down his back, face buried in his chest, over the starburst scar and says, “Take your time.” Strong muscular arms Izuku has known since they were children wrap around him as well, and the overwhelming sense of home and care and warmth fill them both.
“The one who lost his Deku. Katsuki. That version of myself… he lost his Izuku. And,” Kacchan takes a deep shuddering breath, “And when I had performed the Arikahd, the loss and pain he felt… it was surreal.”
Izuku can hear the way the words begin to get stuck in his husband's mouth. He leads them to their bed, making Kacchan sit first, then climbing into his lap to wrap himself bodily around his husband. He once called Izuku a baby hatchling for doing such a maneuver, but he knows that Kacchan loves it and feels more secure each time he squeezes them together in such a way.
“I’m here, Kacchan.”
Kacchan nods his head, burying his face once more into Izuku’s neck, “I know. I know you’re here. But that pain? The sharp, aching, hurt that Katsuki had? That was real. His Izuku was gone. Permanently. And for the first time I felt what it was like to know what would happen if I were to ever lose you. What you must have felt that day when you lost me and brought me back.”
Izuku pets through his husband's hair, scratching at the scalp in the way he likes. Izuku finds his own comfort in the way the scar across Kacchan’s chest feels against the hand he presses there - of knowing he performed one of the most dangerous spells known just to bring his husband back to him. And it worked.
“I wanted to help him so much. The way he screamed and panicked when he saw the other version of you - ” Izuku can feel a wetness begin to form at his shoulder, can feel the aching sorrow down their bond. “It was earth shattering. Never had I seen such grief. Except once… with my dad. And, what I imagine, what you must have felt.” A shuddering breath breaks out between them. Izuku turns to kiss at his husband’s temple, fingers still scratching lightly between blonde strands.
“I spoke with him tonight about it. He knows only a little. But enough. And Izuku,” Kacchan lifts his head to look directly into his eyes. Izuku finds love and determination and though the sadness still lingers it’s slowly being replaced by what Izuku can only describe as hope. “Know that I love you with my entire being. My soul is yours, my heart is yours. And I would rather die with you than ever be left here without my other half. You and me? That’s it. You’re mine and I’m yours and we will meet together in the cosmos, riding amongst the other renowned warriors together. But know that I cannot and will not live without you by my side.”
Izuku’s brain has gone completely blank. He stares at his husband, letting the words wash over him, tears filling his eyes at the beauty in his descriptive love. He can only do one thing - and that is to lean forward the hairbreath needed and press his lips to his husbands.
Izuku pours every ounce of love he can into their bond. Every ounce of pure devotion and care, adoration and passion, light and hope, and a million other things that show he loves his husband as much as his husband loves him.
As they kiss, Izuku unclasps Kacchan’s cape, letting it fall behind them onto the bedding. Kacchan’s hands have moved to Izuku’s waist where he works on unworking his belt. Izuku pours himself into his husband's mouth, licking into him, sharing breath as if they were one person.
Hands move quickly, tearing clothing piece after clothing piece from the other's body, till they are both naked, with Izuku laid out over Kacchan’s warm body against their blankets and furs.
Izuku looks down over his husband where he straddles his thighs and thinks there is nothing better in the world than the view of Kacchan’s red red eyes on him and only him. Izuku ruts forward to slide their growing erections together and they both moan in tandem at the flare of pleasure.
Izuku leans down to kiss Kacchan again; sloppily, tongues moving together as one, tasting the other as they once again shift their aching cocks together.
Izuku uses one hand to open a portal to grab their special oil from the bedside drawer, knowing neither of them would be able to let the other go. Izuku closes the portal immediately and when he goes to unscrew the lid, Kacchan’s hands are there instead.
“Let me.” His voice is gravelly and shrouded in desire. Izuku lets him - he helps by taking the bottle back and pouring a generous amount over his husbands fingers, then quickly screws the lid back on and tosses it near their pillows.
Kacchan warms the oil between his fingers before reaching around them both to press into Izuku’s hole.
“Mmmm, Kacchan.” Izuku breathes out, then leans to press an open mouth kiss to his husbands lips, hips pressing back to allow Kacchan to press in deeper.
Kacchan does, pressing into the hilt of his finger, but Izuku needs more. Can take more already. He communicates down their bond - the need he’s filled with - to take what Kacchan can give him and then some. To be loved by him fully and irrevocably.
Kacchan moans into his mouth and pulls out slowly, to then press in quickly with two fingers. Izuku’s answering keen has him smiling into their kiss and hips jut up to rub their cocks together.
“Gorgeous, Izuku, absolutely gorgeous, baby.” He moves his fingers to spread Izuku’s hole open, taking his time to work against the nerves hidden up inside him. Izuku lights up when Kacchan brushes against them and he has to break away from his mouth to pant into Kacchan’s neck.
“Kacchan, yes, yes, Kacchan.”
They continue in this way, Kacchan working Izuku open on his fingers, shifting to rub their erections together and making out like they did when they were teenagers as Izuku cries above him.
The fingering is starting to border on teasing for Izuku and when he’s had enough - knowing Kacchan would finger and edge him all night if he let him - Izuku sits up and reaches for the oil once more. He grabs at Kacchan’s hand and pulls it out of him - sad at the loss but knowing what’s about to fill him, doesn’t leave him mourning for too long. He pours a generous amount of oil over Kacchan’s hand then guides said hand to his husband's own cock to spread the oil there. Izuku’s hand is laid over his larger one and guides up and down his thick length together and is pleased when a spike of pure lust is sent down their bond.
When satisfied Izuku pulls his hand away to cap the oil and toss it to the side once more. He doesn’t give his husband a second to breathe before he uses a free hand to position Kacchan’s cock and then drops himself on it. They moan in tandem - Izuku loving the feeling of being full, his husband and him connected in their most intimate way. Fingers scrape at Izuku’s hips, leaving red marks and Izuku's own fingers find their place against Kacchan’s chest, spreading out over the starburst scar - the feeling of being here and now, Kacchan alive and well underneath him, surges through him; they’re both alive and together.
Izuku looks down at his husband and locks green with red. He slowly rises up off Kacchan’s cock before letting gravity drop him back down.
“Oh, fuck,” Kacchan grunts, eyes closing for half a second before quickly opening back up. As if he doesn't want to miss one second of their love making.
Izuku repeats the motion, but this time he leans down to kiss achingly soft into Kacchan’s mouth. He slowly begins working himself on Kacchan’s cock and Kacchan uses his hips to meet Izuku on every downward thrust. Their bodies lighting up together, building and building and building the love between them.
Warm calloused hands glide against his body. Breaking Izuku apart in the best possible way and stitching him back together with loving tenderness. Izuku follows patterns he’s known for years - the lines of a body he could get lost in. Izuku pours himself into Kacchan - their bond open and bright between them as their bodies entwine together. Love - sweet and unconditional, never ending and breaking, true devotion and trust - pours itself between them. Izuku finds himself drowning in it - in them. And he doesn’t want to call for help (never has); instead he drags Kacchan down with him and they succumb together.
“You are,” Izuku huffs out breathily, as they both chase their climax, “You are so loved Kacchan. My Kacchan.” Izuku breathes open mouthed against his husbands lips, squeezing around him and cherishing the sounds he makes, “My Kacchan is loved here and now. I will love Kacchan through it all. In every life. In every world.” Izuku sinks down particularly hard and reaches to twine their fingers together, laying them both out by Kacchan’s head.
Red eyes are locked on him as he pulls away and Izuku needs them to stay on him as he says these words. Needs Kacchan to understand.
“There will always be an Izuku and a Katsuki. And in every universe, in every star…” Izuku huffs a breath, he finds tears forming in the red below his and it makes his own tears begin to run down his cheeks, landing on the skin below him, “In every space between the stars, I will love you. An Izuku will always love his Kacchan. We are entwined forever for eternity, Kacchan. There is no you without me. There is no me without you.” He bounces harder, feeling his climax quickly approaching, He squeezes their joined hands, “There is not one of us without the other. You are mine and I am yours. I love you, Kacchan and you are loved in every universe. By me. Your Izuku.”
Izuku and Kacchan come together as one. Tears in their eyes because they both know it to be true. They are souls forever tied together.
There is not one without the other - hand in hand they’ll walk the universe together.
