Nightshift fucking sucks.
At least that’s what Hitoshi hears every night he clocks in. The daywalkers give him looks of pity as they peel off their costumes in the locker room alongside him, patting him on the shoulder, telling him he’s ‘just gotta push through.’ Hitoshi gives them a polite smile and laughs along with them, waiting until they’re gone before rolling his eyes and scoffing.
Night shift is the fucking best. There’s less civilians out so Hitoshi doesn’t have to worry about some innocent bystander catching his quirk, not to mention he doesn’t have to adjust his chronically awful sleep schedule. He’s always been something of a night owl and now it plays to his benefit. There’s also the added bonus of higher pay rates, which Hitoshi can use to afford the finest things in life; black out curtains, expensive pillows and bedsheets, and top of the line mattresses.
He’s an insomniac, not a maniac. When he gets home, the morning sun burning red and piercing its way through the city skyline, he wants to retreat to his heavenly cave and let the sandman do his thing. There are few things in life that can beat out a good night(day?) of rest. Even if Hitoshi can only get in two hour power naps at a time, you can bet those two hours are going to be divine.
Hitoshi actually feels tired tonight as he pulls off his costume and stuffs it in his duffle bag. It’s going to be wrinkled as hell when he puts it on next, but that’s an issue for another time. The streets were quiet enough that he was able to convince his supervisor to let him sneak off early and right now all he can think about is his king-sized bed and his duck-feather pillows waiting for him to join them. He checks the time; 2:33am. It’s not often he gets off work with enough time left to know his omega is still sleeping soundly, his hazelnut scent like an extra blanket on their bed.
Hitoshi is quiet when he enters their apartment, carefully putting away his shoes and slipping on his house slippers. He showered before leaving the agency and rushed home, eager to wrap himself between the sheets beside his love. Usually during the week he only gets a few minutes with Katsuki curled up in his arms since he wakes up so early you’d think he had a competition with the sun.
He scrolls through his phone while he tiptoes through the apartment, mindful of his cat's usual nap spots. Hitoshi’s brow furrows when he looks at his shared schedule with Katsuki—his omega doesn’t have shift the next day. Or any shifts for the next week, for that matter.
Unease spikes through Hitoshi until he opens their bedroom door. A wave of dark-roasted coffee makes Hitoshi’s eyes water nearly as much as it makes him drool. He quickly shuffles to the window to push back the curtains and unlatches the lock, rushing to let in moon-cooled air and soft blue-toned light, ushering out the smell of his omega’s need.
The moon acts as a spotlight on the most beautiful sight Hitoshi has ever seen. With sheets half kicked away and only a tank top on, Katsuki is on full display. He’s fallen asleep on his stomach, one leg hiked up as if he were trying to seduce Hitoshi in his unconscious state.
Katsuki’s skin is flushed and shines with a thin sheen of sweat, but it’s nothing compared to the glistening slick running down his legs. Hitoshi’s alpha nearly leaps out of him, his only thought being take.
His poor omega. Gone into heat, probably just before bed since he seemed fine when Hitoshi was getting ready for work. Katsuki always has such a hard time facing his heats alone, there really is no relief for him if he doesn’t have a knot to sit on.
Hitoshi uses his last two remaining brain cells to put in his rut leave request to his supervisor, knowing Katsuki’s heat is already triggering it. Being mated to an omega hero that’s already submitted heat leave makes it feel redundant, but Hitoshi is thoughtful enough to do it anyway.
He tosses his phone somewhere in the room. It doesn’t matter where it lands, it’s going to be ignored for a week regardless. Hitoshi crawls onto their bed feeling like a predator as he approaches his sleeping omega. So innocent and defenseless, it’s rare to catch his firecracker of a boyfriend so docile.
Hitoshi reaches out to Katsuki’s exposed ass, kneading the plump skin before curling his fingers to leave crescent shaped imprints in their wake. By the end of this week Katsuki will be covered in hickeys and bite marks, stray scratches and some fingertip bruises on his hips, but Hitoshi is kind enough to not rouse him with such aggressive behavior just yet.
His omega stirs regardless, but not quite enough to actually know what’s happening. His body simply reacts to Hitoshi’s touch, leaning into it, pushing back as if to say more, alpha.
And who is Hitoshi to deny such a request? He slides his hands over Katsuki’s fevered skin, pulling his cheeks apart to really take in the beauty of his lover. The moonlight makes Katsuki’s skin look even more milk-toned than usual. Hitoshi dips his finger through the trail of slick, teasingly rubbing his rim. The response from his omega is immediate; Katsuki lets out a sleepy whine and his hole clenches.
Hitoshi presses himself closer to Katsuki, carefully working his finger in between the blond’s cheeks. He’s so tight, even with this much slick leaking out of him. Hitoshi is glad he’s an alpha with restraint, but it’s taking everything in him not to stretch Katsuki open with his cock. He lazily pumps his finger in and out, waiting patiently until there’s no resistance before squeezing a second finger in. Katsuki sighs contently in his sleep.
“So needy for it, aren’t ya, baby?” Hitoshi whispers, his lips ghosting along Katsuki’s neck. He noses his scent gland, finally catching a whiff of pomegranates. It’s a subtle note and only makes its way through the more abrasive scents when Katsuki feels relaxed and pleased. The rare smell is all the encouragement Hitoshi needs to keep going.
Katsuki stirs again, this time rolling his hips. He pushes back into Hitoshi’s fingers and then rocks forward. He’s probably smearing precum all over their sheets, his cock undoubtedly hard and pinned to the silky fabric beneath them. Katsuki’s movements are messy and uncoordinated, unlike Hitoshi’s practiced and careful strokes.
“Fuck, Kats, you don’t even need to be awake to be so desperate,” Hitoshi whispers again. He’s losing his composure by the second, but he’s determined to not wake Katsuki up until he’s hilt deep in the omega’s ass. He prods a third finger in, carefully, knowing this will be the make or break point for his sneaky indulgence.
No matter how many years they’ve been together, no matter how many times they fuck, Katsuki is always as tight as the first time and he always, always, cums from the stretch of three of Hitoshi’s fingers. Maybe it has a bit to do with Hitoshi’s memorization of Katsuki’s body—where to tease, where to curl his fingers to play the blond like a violin—but Hitoshi prefers to tease his mate for just being so easy.
While he works his way into Katsuki’s hole, his unoccupied hand makes quick work of pushing down his sweats and boxers just enough for his cock to breathe. He’s achingly hard after being clouded with his omega’s heat pheromones and bearing witness to the sinful display his little angel effortlessly performs. Fuck getting undressed, all he cares about is being ready to shove his cock where it needs to be.
With a little bit of impatience Hitoshi gets his ring finger to glide into Katsuki. He curls his middle finger at the perfect angle and lightly bites down on Katsuki’s scent gland to really pack a punch. The result is immediate.
Katsuki’s back arches as his hole spasms around Hitoshi’s fingers. The omega cums with a shout, his legs shaking while he rocks himself back onto Hitoshi’s hand.
“Hnngh, ‘Tosh,” is all Katsuki’s able to say with his sleep-heavy tongue before Hitoshi pulls his fingers out of Katsuki’s slicked up hole and shoves them into the sleepy omega’s mouth.
Hitoshi doesn’t hesitate to shove his cock in Katsuki’s fluttering hole, still tight but accommodating to his girthy length. Katsuki gags around Hitoshi’s fingers, drool and slick running down his chin.
“Finally awake, baby?” Hitoshi grunts in his ear as he slams his hips forward, burying himself inside of Katsuki. The omega moans around his fingers, swallowing his own slick and gagging when Hitoshi presses further in. “You should be more considerate, really. My omega in heat, ass out like a fucking all you can eat buffet waiting for me? You had to have known this would happen, doll.”
Hitoshi fucks into Katsuki hard, their bedframe slamming into the wall with each thrust. Katsuki tries to speak, but only choked off and gargled moans tumble past his lips. Hitoshi loves when Katsuki’s in heat—he turns into such a mess under his alpha’s touch. Even with Hitoshi giving him nearly all he’s got, Katsuki is still wiggling his hips in tandem to ensure he’s getting every centimeter Hitoshi has to give him.
Feeling merciful, Hitoshi drags his fingers down Katsuki’s tongue, feeling the scrape of his teeth against the pads of his fingers before smearing the slick and spit mixture down Katsuki’s chin, trailing down his neck and continuing until he’s traversed Katsuki’s body and settles his hand on the omega’s hip. He pulls out completely, ignoring the frantic whines from his lover as he flips him over to his back.
He doesn’t give Katsuki even a moment to catch his breath before he slams their lips together. Katsuki tastes like sleep and slick and Hitoshi is all too eager to lick into his mouth, getting drunk on the taste. It’s not until explosive hands anchor themselves into Hitoshi’s hair and pull that the alpha stops and actually looks at Katsuki.
His pupils are blown wide, his hair wildly unkempt and sticking to his forehead by the sweat that dots his brow. Hitoshi can see the need in Katsuki’s expression, only thinly masked with a look that could kill a weaker man.
“How are you going to wake me up like this and then stop fucking me?” Katsuki growls, his fingers nearly pulling the hair out of Hitoshi’s scalp. “Get that useless knot inside of me before I blow the damned thing off!”
Hitoshi laughs until Katsuki pulls his hair again, even harsher. Hitsoshi’s smile fades and his eyes narrow. He loves that his omega has a bit of an attitude—it keeps Hitoshi entertained, after all—but he also expects Katsuki to behave. Which Katsuki is fully aware of, even with his mind muddied from the heat.
“Katsuki.”
One word in a deep and commanding tone is all it takes for the omega to stop, his hand releasing the tufts of hair they were tugging, fingertips massaging Hitoshi’s scalp in apology.
“‘M sorry,” Katsuki mumbles, looking away with a hot blush kissing his features. “Hurts. Need you.”
Hitoshi sighs. Katsuki’s hormones really get the best of him at times and Hitoshi knows his omega prefers to be obedient and be spoiled in return. He leans forward and presses a gentle kiss to Katsuki’s forehead.
“There’s better ways to get what you want,” Hitoshi whispers against Katsuki’s warm skin.
“Alpha, plea—”
Hitoshi doesn’t let him finish, lining his cock with Katsuki’s entrance and slamming his way home. He punches the air out of Katsuki, leaving the omega gasping, mouth open, tongue lolling out as Hitoshi picks up right where he left off with his brutal pace.
“‘S not so bad being nice, is it, pretty thing?” Katsuki rapidly shakes his head. “I love when I get to spoil you, kitten. Wanna give you everything, all the cock my little slut desires.”
Katsuki groans, his eyes squeezing shut. He blindly reaches out, grabby hands pulling at Hitoshi’s hoodie, using the black fabric to pull his alpha close. Hitoshi goes willingly but is sure to keep his rhythm steady. His knot is already forming and he knows it won't be long before he needs to shove it inside of Katsuki.
He’s misjudged the timing once, once in their years together, and Hitoshi knows there is nothing more terrifying than Bakugou Katsuki in heat without a knot he was supposed to be locked onto. Katsuki still doesn’t let him live it down, telling anyone that will listen that Hitoshi has a useless knot that he doesn’t know how to use.
“Knot, knot, fuckin’ please, ‘Tosh,” Katsuki pants, pulling Hitoshi in and burying his face in the crook of the alpha’s neck. His small fangs scrape along Hitoshi’s scent gland and he feels that familiar curl of heat in his lower stomach, the feeling that always precedes his knot popping.
Katsuki must know just as well because he hooks his legs behind Hitoshi, his heels digging into the small of Hitoshi’s back. At the same time he sinks his teeth into the alpha’s neck and cums untouched, his hole tightening and squeezing Hitoshi’s cock enough to send the alpha over the edge.
He squeezes his knot in at the perfect moment, swelling inside of Katsuki and securing his place inside. Cum pumps into the omega, his stomach already bulging from Hitoshi’s thick length. Hitoshi’s inner alpha swells with pride, the gratification of knowing his omega is being well bred and his heat needs are being met.
Katsuki laves his tongue over the bite mark on Hitoshi’s neck. The alpha can tell without looking that he’s likely bleeding. He chuckles at the thought of yet another bonding mark, as if Katsuki’s inner omega thinks they need fresh mating bites every heat.
Katsuki’s always quiet after he’s tied to Hitoshi. He focuses on giving Hitoshi silent displays of thanks, rubbing soothing circles into the alpha’s skin, kissing his scent glands, holding him close. Hitoshi cherishes these moments, ones where they feel like the only two people in this world.
Hitoshi carefully stands up, which is easy enough with Katsuki still holding onto him like a koala. It’s a challenge, but he manages to chuck off his sweats and boxers and get to the kitchen to grab snacks and water for their room all while Katsuki stays sated on his knot.
“Think you can let go of me long enough to get this hoodie off?” Hitoshi asks once they’re back settled in their bed. The doting alpha even managed to grab a few things around their room to form a makeshift nest.
Katsuki grumbles but releases his hold around Hitoshi’s neck and gives the alpha room. He can hardly get the hoodie off before Katsuki’s taking it.
“You know that’s got your cum all over the front, right?”
Katsuki scoffs and rolls his eyes. “That just means it smells like both of us, dumbass.”
“Mmm, I love my disgusting little freak,” Hitoshi hums back with affection. Katsuki flips him off, but he still puts the hoodie on and drags Hitoshi back into his embrace.
They get comfortable and their breaths begin to slow. Hitoshi’s knot can stay strong for hours once he’s thrust into rut so they usually nap together afterwards. Katsuki falls asleep first, he usually does, and Hitoshi uses the time to admire his love.
From his soft blond hair pressed into Hitoshi’s shoulder to his pale lashes kissing his cheeks. The way his lip forms a precious little pout when he sleeps. Hitoshi didn’t know it when they first got together, but Katsuki is an all night cuddler as well. He latches onto Hitoshi and won’t roll away unless his alarm forces him to.
There are no alarms waiting for them now, though, Hitoshi remembers with a fondness warming his heart. Just a week full of little moments like this, followed by marathons of fiery passion. Hitoshi smiles as he drifts to sleep, looking forward to his knot deflating to he can tear Katsuki apart all over again.
