Work Text:
It had been a long week. A villain had attacked a popular tourist trap, destroying several buildings and trapping hundreds of people beneath the rubble. Katsuki had stayed in a makeshift tent the Hero Commission had set up so the heroes could work 24/7 to help, meaning he hasn’t been home in days.
He also hadn’t gotten that much sleep either. So when he finally drags himself through the front door, all he wants to do is to get to bed.
...maybe get some food first.
He blinks at the kitchen, but the thought of doing anything, even reheating up whatever Eijirou had leftover, just sounded too much for him. He'll eat like a starving man after he gets some sleep.
Katsuki undresses, and for once he doesn’t care as he throws his clothes to a messy pile on the ground. He falls into the bed, naked as the day as he was born. As soon as his head hits the pillow, he’s out.
When Katsuki wakes up again, he already knows that he hasn’t slept enough. His body is still sore, limbs barely able to move. The only reason he even flutters his eyes open is that he can feel hands on his shoulders, on his back, on his ass.
“Hmm?”
“Hey, Katsuki,” his husband, Eijirou Kirishima, whispers, pressing a kiss against his head.
Katsuki hums, eyes fluttering back close. “Did you eat?”
Eijirou chuckles. “I think I should be asking you that.” Eijirou goes back to massaging him and if Katsuki bothers to strain his ears, he can hear the other man singing quietly under his breath.
Katsuki can feel himself sinking back into darkness, lulled by his husband and the sleep he desperately needs.
“Katsuki?”
“Hmm?”
“Are you hurt anywhere?” Eijirou’s voice is soft, a bit sing-songy. His hands never stop moving.
Katsuki relaxes completely into the bed. “The local heroes had taken down the villains by the time I got there. I was just involved in the rescue part.”
“That doesn’t answer my question.”
Katsuki makes an effort to peek up at him. Eijirou is leaning over him, his long red hair hanging to the side, like a waterfall. Eijirou stares back and even though his hands are soft and his voice is soft, his eyes are different. Are dark, filled with need and longing, a desire to connect them once again.
Katsuki closes his eyes and arches his back up into Eijirou’s hands. “Nah. I was perfectly fine the entire time.”
He can feel Eijirou relax on top of him. Katsuki smiles to himself. “I missed you though,” he continues.
“You already know how much I have been aching to have you near me again,” Eijioru says, giving his head another kiss.
Katsuki hums, tilting his head and letting him continue to kiss down to his neck when Eijirou laves a tongue across the sensitive skin.
Katsuki shivers. “I haven’t showered yet.”
“Do you think I care?” Eijirou growls, the timber of his voice rumbling against him.
Katsuki smiles. He gives back into that calming space of in-between sleep. “You know, I’m still tired. Do you think you could rock me to sleep?”
Eijirou pauses for just a second. Then Katsuki can feel his smirk press into the skin of his neck. “Oh, I can absolutely do that.”
Eijirou’s warmth barely leaves him, but Katsuki still whimpers. Eijirou pets a hand through his hair, comforting before he’s back. He makes sure to press as much of himself that he can against Katsuki. Considering how much all around bigger he is than Katsuki, it isn’t hard.
His hands are back, massaging into Katsuki’s upper back, turning Katsuki into jelly. Slowly, so slow it hypnotizes Katsuki, the hands slide down his back, traces over each scar and every muscle.
The hands wrap around his waist, gripping and Katsuki is almost knocked out of his lull by the sheer fact that those hands could almost wrap completely around him.
“Fuck,” Eijirou whispers and Katsuki can practically see the heat in those eyes as he stares down at him.
Eijirou stays there for a few more seconds before his hands are on the move again. Inch by inch, they slide till they can cup Katsuki’s asschecks. He squeezes and spreads them, getting Katsuki to moan, before he lightly taps at them, jiggling the flesh.
“Perv,” Katsuki whispers.
“You love it,” Eijirou whispers back.
Katsuki can’t argue with that.
Eijirou kisses his way down Katsuki’s spine, bit by bit, all while his hands continue to play with Katsuki’s ass. Katsuki knows where this is going but the first scrape of teeth against his cheeks. His toes curl and a breathy moan escapes his throat.
Eijirou bites down harder, and Katsuki’s back arches.
“Shush, Kat,” Eijirou says, way too smug. “You’re supposed to be resting.”
If Katsuki had the energy, he would flip him off.
Eijirou knows, and he chuckles but Katsuki doesn’t have time to make a snarky comment before Eijirou bites the other cheek.
“Shit,” Katsuki moans out, rolling his ass back into Eijirou’s touch.
Eijirou gives both marks a kiss. He lifts up, for just a second, and Katsuki hears the bottle of a cap opening up. When Eijirou returns, two of his fingers are slicked with lube. He presses them against Katsuki’s hole, circling the rim. “Ready for me, baby?”
“Hmmm,” Katsuki says, which is answer enough.
The breath leaves him when one finger sinks in, slow and steady, up to the knuckle. Katsuki tries to press back, to take more, always so greedy for more, but Eijirou keeps a steady hand on Katsuki’s waist.
“Resting, Kat,” Eijirou says. Commands. “I know you didn’t get a lot over the week.”
Katsuki grumbles, but honestly, it’s not much to relax into the mattress and let Eijirou do all the work, his body still too tired to want to do anything but what Eijirou asks.
“Good boy.” The voice is honey-smooth, a low purr that just eases Katsuki’s mind down into that nice and safe space he loves. “Let me pamper you, baby.”
Eijirou stays slow and steady, his fingers sliding inside Katsuki, getting him wet and sloppy. He holds down Katsuki and whispers praise in his ears as he works Katsuki open. Katsuki’s breathing is nice and slow, taking the finger fucking with ease, barely complaining even as Eijriou keeps his slow pace when he adds a third finger.
“I’m open,” he mumbles after what seems forever.
“Not yet,” Eijirou says. “Not till I can slide right in with ease.”
Katsuki thinks he already can but he just whimpers and cuddles his pillow closer. Eijirou kisses his ear, then the back of his neck.
“Good boy.”
Katsuki continues to fall into the warmth of his mind, in the open arms of sleep as it welcomes him back home, trusting the knowledge that his husband will take care of him.
Eijirou presses against his prostate, making Katsuki’s cock jerk, precum dripping onto the mattress.
“Is that good, baby? Do you feel good?”
“So good, Ei. Please, more?” Katsuki buries his head in his arms.
“Of course. Anything for you.”
The fingers disappear, just for a moment as Eijirou re-lubes them. Then he presses four fingers in. Katsuki grunts at the fullness, already looking forward to Eijirou’s cock, to how even with four fingers inside him, that glorious cock will still stretch him.
Eijirou’s fingers disappear again, the end of the lube bottle is being pressed against his hole. Lube floods him and Katsuki grunts.
Then he’s given what he wants, the tip of Eijirou’s cock slipping inside. Eijirou goes slow, steady, like he has all night. Filling up Katsuki in the most gentle way he can. He presses in, squeezing past his prostate, making Katsuki cry, before he settles balls deep inside.
Eijirou settles his weight on top of Katsuki, pressing him into the mattress. His warmth is all-consuming, a reminder that like this, Katsuki is the safest.
Eijirou kisses his ear. “Go to sleep, Katsuki. I got you.”
Then he begins to rock, small and steady, his cock barely leaving the warmth of Katsuki’s hole before thrusting back in, getting as deep as he can.
Rocking Katsuki to sleep, just like he asked.
