Work Text:
Izuku slowly opened his eyes, shifting slightly to the right to turn his head and face the blonde next to him. He was still asleep, chest rising and settling while the sunrise kissed his face and the top of his biceps. He looked at Kacchan and couldn’t help but smile at the sight in front of him. He loved him so much, he loved the quiet mornings that allowed him to sit and enjoy his boyfriend. He turns so that his body’s facing Katsuki, hand gently rubbing his scarred hand onto soft, warm skin and blonde stubble. Katsuki fidgets at the movement and his eyes slowly break open, taking in the sight of green curls in front of him.
He nuzzles into Izuku’s hand, taking his own to cover the hand on his face and kiss the inside of his palm. Izuku’s heart swells and he throws himself forward to hug Katsuki, holding him tight and peppers kisses all over his face and neck. They both chuckled as Katsuki grabbed him, placed him in his lap, and sat them up against the headboard. “Morning, nerd” Katsuki says with a smirk, running his nails gently across Izuku’s arms. Izuku melts into the feeling and shudders, smiling back at him with pride. “Good Morning, Kacchan” he says, his freckles drowned out by the pink spread across his face.
“What do you say we stay in late today, hm? We don’t work until Wednesday” he asks Katsuki, who grins widely at the suggestion. Katsuki could spend every day in bed with this nerd and never get tired of it. He scoops up his boyfriend and lays them in the bed so that Izuku’s back is nuzzled into Katsuki’s chest. “You don’t have to tell me twice, sweet cheeks” as he nips at Izuku’s bare neck and grabs his waist, pulling him tighter to Katsuki and his growing erection. The bump on Izuku’s ass cheek was enough to send his insides fluttering, sending waves through his body like firecrackers.
Katsuki continued to kiss his neck up towards his cheek, biting down and then kissing it to soothe the burn. Izuku could feel his own arousal cause his pants to swell and precum-stained his boxers. He reaches an arm behind him to dig scarred hands into Katsuki’s soft, spiky locks and tighten around it at the scalp. He bucks his hips back and rubs himself into Katskuki’s erection, causing him to groan deep in his chest, almost flipping a switch in his brain. He runs his fingers down Izuku’s abs and slips in between his boxers to grip him tightly, spreading the precum all over his throbbing shaft. Izuku loved how his boyfriend knew exactly where to touch him and make him squirm.
He continues to nibble and bite the skin right underneath Izuku’s ear as he begins a steady pace of pumping him up and down. Izuku’s head flies back straight onto Katsuki’s shoulder as he rides out the shocks of pleasure that shoot down his dick and through his chest. Hiss ass clenches as Katsuki brings his hand down his shaft to pump him deeply from the base of his cock, fondling his balls in the process.
“Fuuuck Kacch- ah please, please” he moaned into his boyfriend’s ear, waiting for his Kacchan to give him everything he wants. He turns Izuku slightly so that his back is now to the bed and slips off Izuku’s boxers and to leave him bare, except for the Dynamight T-shirt he was sporting (Katsuki fucking loved the way he looked when he fucked Izuku in his clothes). He tucks his legs under Izuku’s and uses one of his knees to spread him wide open, his cock and hole weeping for Katsuki’s touch. Katsuki began to use his fingers to pinch and pull on Izuku’s nipples just the way he liked, using his quirk to warm them after to soothe the sting. Izuku loved Kacchan’s heat, it turned him on in a way that he didn’t quite even understand, but his body understood quite well. Kacchan grabs the bottle of lube from their nightstand and pours it in his hand to warm it with his quirk before rubbing it onto his lovers hole.
“I fucking love having you like this, Izuku. You’re so fucking hot you drive me crazy” He moans as he thrusts a finger up to his knuckle into his green haired lover, watching his eye roll back in ecstasy at the pleasure. He slowly pushes the rest in until he’s at the knuckle and curves his finger just the way Izuku likes it. Izuku used one of his arms to latch around Kacchans neck while he looked down as Kacchan plunged deeper and deeper into him. As his head rolled back, he bit and sucked at Izuku’s neck, littering it with small purple bruises. This caused the freckled boy below him to let out the most guttural moan that sent shocks down his spine. Katsuki didn’t care, he wanted the world and all those fucking extras to hear, to know who he belonged to. “KACCHA-“ he screams as a thick shot of cum shoots out of him, painting his chest and part of the t-shirt he was wearing. “More, more please just fuck me through it, please kacchan” he pleads, holding Kacchan’s inside of him, his fingers still curled and near the bundles of nerves.
Katsuki almost busted on himself right there, but he bit his tongue and continue to thrust his thick fingers into Izuku. He writhed and sobbed, choking on spit and his tears as he rocked and rode on his boyfriends fingers. Katsuki had enough, so he decided to dip down for one more deep, sloppy kiss before turning himself to line up with Izuku’s hole. He lubed himself up and slapped his dick lightly on Izuku’s, causing them to both groan and rut against each other. He sits back a bit and gently pushes into Izuku, breaking the barrier of his puckered rim and feeling the hot warmth bite down on his cock.
“Fuck, baby you’re gonna make me cum” he said with a huskiness that only made Izuku want to be rammed into the mattress. He ground his hips into Katsuki, silently begging for him to press all the way into him. He complies and shoves himself in until he bottoms out, tucked nicely into his boyfriend and basked in the soft walls that kissed the tip of his leaking dick. He takes both hands and grips the sides of Izuku’s face to pull him into each other, sending his tongue through every crevice of his mouth. He ate up all his little mewls and cries, licked his salty tears and kissed his eyelids. He grabbed a small tuft of green curls and used it to pull Izuku’s head to the side, letting him mark his neck up and down like a collar.
“Come in me Kacchan, fuck” he slurred out, eyes blurred by his tears again as Kacchan snaps his hips and jotls his nerves into overdrive. “FUCK!” he screams, his heels kicking into Katsuki’s back and his nails dug deep into the fleshy muscle. Katsuki continued his brutal pace and watched as his boyfriend below him became so pliant and obedient to him. “Fuck you’re such a good boy, Izu. Gonna give you it all” he says as he watches Izuku nod repeatedly, thanking Kacchan and dragging him down to embrace him. They both hug each other tight as they grind their bodies together, the air filled with the smell of their sex and Kacchan’s sweet scent. Izuku has way too many times where he used to sniff Kacchan’s shirts while he was away on missions, using it as an anchor to help scratch the itch he needed while his boyfriend was away. Now that Katsuki was back and able to spend time with him, he wanted to be all over his Kacchan. He closed his grip on Katsuki’s hair tighter and used his other hand to squeeze at Katsuki’s thighs. Katsuki loved when Izu played with his ass, especially while he was balls deep inside of him.
The touches only rev Kacchan up, increasing his thrusts and holding onto Izuku for dear life. “Fuck, I love- AH you kacchan” he sobs through the thrusts, his face a watery mess as Katsuki splits him open. Katsuki begins to fuck harder and harder until the dam breaks and he shoots deep into Izuku, riding out his orgasm as his boyfriend writhed below him. He continued to pump into Izuku while jerking him off, begging for him to come. “C’mon be a good boy and cum for me, Izu” he praised and not even three thrusts later, he was shooting all over himself and Katsuki’s hands. They both panted and collapsed into each other, clinging onto each other to enjoy the afterglow.
Izuku pulled Katsuki on his chest so that he could run his nails onto his back, something Kacchan loved and silently pleaded for after sex. They breathed and sighed as they kissed each other in bed, tossing the dirty sheets to the floor to be dealt with later. “I love you, Izuku” he says as he turns his face to look straight into his eyes. “I know I don’t say it enough, but I fucking love you.”
“Oh, Kacchan” Izuku says, “I love you, too. More than you can even imagine.” He smiles and runs his fingers on Kacchan’s cheek, drinking in the sight of a sleepy Kacchan in his lap. He grabs the sheets and throws it over the both of them, letting the warmth of the morning sun lull them back into a deep sleep. Oh well, they can go out another day.
