Izuku admits that at face value, he does appear like he would be the clingier one between him and his boyfriend. An absolutely fair assumption to make given Izuku’s propensity for pda. He likes to hold hands and cuddle up to his boyfriend no matter where they are, sue him.
In the privacy of their shared apartment, however, Katsuki latches onto Izuku at the first available opportunity and Izuku really can’t find it in himself to mind all too much. This usually ends with them in the exact position they’re in now, laying in bed in their comfortable clothes, limbs tangled up together, not knowing where one of them begins and the other ends. Izuku truly could not think of a better way to end his day than laying in bed with his heart incarnate.
Katsuki’s body is draped over Izuku, his head tucked into Izuku’s neck and his arm wrapped around his waist, holding Izuku close to him. Izuku is carding his fingers through Katsuki’s hair when he begins to feel light kisses pressing into his neck, tickling him more than anything.
“Leave me alone,” he says in between laughs, trying to push Katsuki’s face away from him.
“God no,” Katsuki whispers reverently against his neck, sending a shiver up Izuku’s spine as he drops his hands back to Katsuki’s hair, holding on a bit more tightly now. Katsuki took this for the green light that it was. He shifts so he’s leaning on one arm above Izuku and begins leaving open mouth kisses up and down his neck. Izuku tilts his head to the side to allow him better access, letting out breathy moans as Katsuki kisses and licks his way up to his jaw.
Izuku brings his hands underneath Katsuki’s shirt, scratching down Katsuki’s back, leaving him to groan right into Izuku’s ear, “ Fuck , baby, I missed you so much,” he says as he grinds his hips against the leg Izuku has slotted between his own.
Izuku lets out a moan at the feeling of Katsuki rubbing his hardening cock against his leg, “Missed me? You saw me this morning, we live together.”
“You know I can never get enough of you, baby. You know I can never get enough of this .” He says, running his hand along Izuku’s body until he reaches his shorts, hand sliding underneath the waistband before he’s groaning again. “ Fuck , you’re already so wet for me baby.”
Izuku moans at the feeling of Katsuki’s fingers rubbing his clit, “Oh fuck yeah, touch me, please, please, please.”
Katsuki lifts his head from where he had continued to suck marks into Izuku’s neck so he could watch Izuku beg, “Yeah baby? You want me to touch you more?” he says as he slips a finger inside of him, “This what you wanted baby? You wanted your Kacchan’s fingers inside you?”
“Stop being a tease,” Izuku says, breaking into a moan as Katsuki starts rubbing his clit with his thumb.
“A tease?” Katsuki says with a grin, “I don’t know what you’re talking about, angel .” Katsuki slips another finger inside of Izuku.
“More, more, more. I need more. I need you . Katsuki . My love .” Izuku begs, nails scratching at any part of Katsuki he can reach as he attempts to fuck himself down onto the long fingers inside his pussy. Aching to get them even deeper.
Syrupy sweet desire spreads throughout Katsuki as he groans, slipping his fingers out of Izuku so he could sit up, ripping Izuku’s shorts off of him and pulling him into his lap. He quickly pulls Izuku into a heated kiss, slipping his tongue in his mouth, one hand tangled in his curls, tugging Izuku’s head into the exact position he wanted him. His other hand grabbing Izuku’s ass, desperately grinding Izuku onto his still clothed cock, leaving the front of his shorts damp.
Izuku’s hands leave their place on Katsuki’s shoulders as he reaches down, scrabbling at Katsuki’s shorts, trying to reach a hand inside but he gets interrupted every time Katsuki drags his pussy back and forth along his cock, “Katsuki, I want to feel you. I need to feel your cock, give it to me.”
“Whatever you want, sweetheart.” Katsuki says as releases his grip on Izuku and pushes him backwards onto the bed, tugging his own shorts and boxers off as quickly as possible as Izuku pulls off his own shirt. As soon as Katsuki’s clothes hit the floor, Izuku is reaching for him, pulling his shirt off of him and then seating himself back in his spot on Katsuki’s lap. Izuku begins leaving searing, open mouth kisses along the column of Katsuki’s neck as Katsuk tilts his head back and settles his iron grip on Izuku’s waist, desperate to continue grinding up into Izuku.
Izuku grabs Katsuki’s cock, rubbing the head of it against his clit as he drops his head and latches onto Katsuki’s shoulder, his moans muffled as he bites down. Katsuki curses and attempts to rut against Izuku, trying to slip himself further into the folds of Izuku’s dripping pussy. Izuku smiles against Katsuki’s shoulder and continues to rub Katsuki’s cock against his pussy, slowly making a bigger and bigger mess until, finally letting Katsuki slip inside. Katsuki lets out a low moan as Izuku sinks onto his cock, pulling Izuku into a messy kiss and licking his way inside his mouth. Katsuki tightens his hold on Izuku hips and begins lifting him up and down enjoying the slow drag of his cock almost as much as Izuku, who tips his head back, moaning so loud that Katsuki spares a fleeting thought to their poor neighbors.
“You feel so good, so perfect. My pretty little angel . You like taking my big cock, don’t you baby?” Katsuki says, rambling praises into Izuku’s skin before leaning them both over until Izuku ends up on his back, wrapping his legs around Katsuki’s waist. Katsuki leans back, grabbing the backs of Izuku’s thighs and pushing them down, folding him in half, “Look sweetheart, look how well your pretty little cunt takes my cock. You look so good like this baby, I could just sit here and fuck you all day.”
Izuku lifts his head and stares at Katsuki’s cock disappearing inside of him, his pussy tightening at the sight, enjoying the drag of his lover's cock along his walls.
“ Fuck yeah , you like that baby? You like watching me fuck my cock into that perfect cunt?” Katsukis groans, slamming into Izuku with a loud smack. “Yeah you do,” he grinds his hips, trying to shove himself as deep inside Izuku as he can, “you love taking my cock.”
“Kacchan. Please .” Izuku whines, trying to fuck himself on Katsuki’s cock but unable to move because of Katsuki’s tight grip on his thighs, holding him down, “ More .” Izuku wraps his arms around his legs and pulls , folding himself completely in half.
“Oh shitshitshit , that’s right angel, hold yourself open for me. Don’t worry your pretty little head, darling, your Kacchan’s gonna give you everything you need.” Katsuki grips Izuku’s hips and starts fucking into him, setting a brutal pace that has tears springing to Izuku’s eyes.
Izuku begs and babbles incoherently, letting go of his legs to run his hands along Katsuki’s arms and shoulders as Katsuki drapes his body over him, hips still pistoning at an unforgiving pace, ducking his head down so he can capture Izuku’s lips in a bruising kiss, Izuku quickly parting his lips with a moan, letting Katsuki slip his tongue inside his mouth. Katsuki moans, licking into Izuku’s open mouth only to groan loudly as Izuku begins sucking on his tongue with a fervor Katsuki has only ever seen him have while on his knees. Katsuki jolts his head backwards, having to pull away to try and gain some composure and keep from cumming on the spot.
Izuku is hardly deterred, he lifts his head to chase after Katsuki and when he realizes he can’t reach his mouth due to the distance between them, he drags his tongue along Katsuki’s chest, tongue dipping into Katsuki’s collarbone as Katsuki’s one handed grip on his hip tightens, threatening to leave marks that Izuku will cherish until they fade, or get covered with new, fresher marks. A much more likely case.
“ Fucking shit ,” Katsuki says, pulling back up onto his knees, running his hand along Izuku’s legs and kissing the ankle resting on his shoulder as he slows his hips down, “you look so pretty like this sweetheart. Crying and begging and taking my cock so well. Tell me what you want, baby.”
Izuku is squirming, trying to get Katsuki’s thick cock back inside of him, “Kacchan, please. More. Please keep fucking me.”
“ More , baby. What more can I give you?” Katsuki asks, his lips pulling into his signature smirk as he returns his hands to Izuku’s waist, pulling him closer and grinding into his tight heat.
“ Ah ! Kacchan, Katsuki, please, please. Give it to me, want it. Want it so bad.”
“What do you want, angel ? C’mon, use your words,” Katsuki punctuates his sentence by pulling his cock almost completely out of Izuku before slamming back into his dripping cunt.
“ Cum ! Please, I want you to cum in me, I want your cum, I need it, pleasepleaseplease ,” Izuku cries out.
“Fuck yeah, baby, you want your Kacchan to cum in you?” Katsuki says droping Izuku’s legs so he can wrap them around his waist and leans over Izuku, one hand tangled in his curls pulling his head back so he can suck bruises into the column of his throat and the other hand on his hip, pulling him deeper onto his cock with each thrust.
Izuku moans loudly, “ Yesyesyes , please fill me up with your cum. I want it so bad, I want you to cum deep inside my pussy.”
Katsuki’s hips speed up without permission as he leans back to get a proper hold on Izuku’s hips, “Yeah baby? You want me to fuck my cum deep into that pretty little cunt?”
“God yes,” Izuku starts breathily, hands gripping the sheets above his head tightly, “fuck me, fill me up with your cum, I wanna be so full, I can feel you dripping out of me. I want my pussy to be so full of your cum that you can slide right into me whenever you want.”
“Holy shit ,” Katsuki groans, “I’ll fill you up baby don’t worry. By the time I’m done with you, my cum will be dripping out of you for days. Who’s my pretty little cum slut?”
“ Ah !” Izuku shouts as Katsuki continues fucking harshly into him, “ Mememe , I’m your little cum slut!”
“Fuck yeah you are, come on baby, cum for me angel .”
Izuku’s orgasm pools low in his stomach, each well aimed thrust of Katsuki’s hips sets every one of Izuku’s nerves alight until he’s pulling at Katsuki’s arms to bring him flush against him. Chest to chest as he buries his head into Katsuki’s shoulder, Katsuki sliding his hands underneath Izuku’s back as he pulls him as close as possible, hips still moving in time with every stuttering breath and moan they release, the room filled with the euphonious sounds of their love as Katsuki’s orgasm steals the breath from his chest, Izuku following soon after, Katsuki groaning with the overstimulation of Izuku’s walls squeezing his spent cock, milking every last bit of cum from him.
They lay together, limbs entwined, not knowing where one body ends and the other begins. Sweat quickly cooling on their skin when Katsuki slowly pulls out, standing and leaving the room, Izuku rolling himself up in the comforter beneath him and closing his eyes, still basking in his post orgasm euphoria. He hears a huff of laughter before he’s unrolled from his blanket burrito and lifted into a pair of strong arms. Izuku hums, wrapping his arms around Katsuki’s neck and snuggling into his chest as he’s carried bridal style to the bathroom. Katsuki sets him down under the warm spray of the shower before stepping in right beside him. Izuku leans his head back against Katsuki’s chest and allows him to begin scrubbing shampoo into his hair.
Izuku truly could not think of a better way to end his day.
