Chapter Text
''Fucking stop that!'' Deku barks at him, sounding stern.
Well, at least- as stern as one can when their ear is enthusiastically nibbled on.
He's mad, Katsuki knows he is, after all- the Alpha had insisted, rather vehemently, for him to not go to work tonight, not while in heat.. but Katsuki did anyway.
The 600 bucks in tips from drunk horny Alphas he's got in his pockets- were definitively worth it, even if Deku doesn't agree.
So yea, Deku is pissed. Fucking furious, actually. The pounding vein on his temple looking about ready to pop, the tension corded between his neck, shoulders, arms, wound so tight- he looks about ready to spring apart, explode all over the place in a million little pissed off pieces, and Katsuki might feel- maybe- just a little bad.
Especially because Deku came and picked him up at work after his own shift ended, as he always does. As he always will, no matter how mad he is at him; because his Alpha is just reliable- and impossibly sweet like that.
It's the sexiest thing about him.
Katsuki coos softly, sliding a hand up Deku's thigh, his fingers dancing up higher and higher, pinky just brushing the edge of the zipper - only for Deku to snatch him by the wrist and angrily toss his hand back into Katsuki's own lap- with a vicious, ''Get your fucking hands OFF of me''.
Usually he tries to be mindful of Izuku's temper. Not because he's scared of the Alpha or anything as ridiculous as that, but- because he knows Deku really is trying his hardest to manage his anger-issues better. Control himself to not go completely ballistic over every little thing that bothers him.
He also knows that whenever Deku's wound up like this- he doesn't even want to touch Katsuki, like- at all. Because no matter how much Katsuki trusts him, Izuku doesn't trust himself.
But sometimes.. sometimes Katsuki just can't help it. Likes to rile him up, just a little. Not to be mean, but to have Deku get just mad enough to fuck him like a dumb raging animal.
A healthier outlet- than running around punching walls or- just swallowing all his anger down, if you ask him. Shit's gonna give him a stomach ulcer.
Undeterred by the Alpha's rebuff and ignoring Deku's nagging about 'putting his damn seatbelt back on' and 'sitting his ass back down right', Katsuki continues to kiss and suck and bite at Deku's throat- the way he knows the Alpha goes crazy for.
Deku moans. Then instantly snaps his mouth shut, frowns, muscle in his neck ticking with how hard he's clenching his jaw.
Katsuki watches him take a deep anger-control breath, steering wheel creaking with the death-grip he has on it. Sees the way Deku flexes his hands, doing that psycho thing he does with his fingers- where he pushes his thumb against each joint, cracking them one by one. Crack, crack, crack- he goes, like he's about to go fucking mental, complete fucking ape.
It just makes Katsuki even hotter between the legs. Makes him feel all fizzy and itchy all over. Pussy so annoyingly horny and lonely. So wet- that he can smell himself in the air, all hot and spicy.
Uuuuggh~ He's terrible, just wants to tear a damn hole in his pants and have Deku fuck him through it.
Yes, when Deku is angry like this- he gets really stingy with his cock. Doesn't want Katsuki anywhere near it. But Katsuki has learned from early on in life- to just take what he wants.
Deku trying to keep at least one hand on the steering wheel- in an attempt to not land the truck in a ditch, gives Katsuki enough of an advantage in their slap fight to undo the Alpha's utility belt, eventually fish his cock out, and make a head dive for it. Popping the head into his mouth like a sucker, he runs his tongue around the tip with a moan.
Fuck, that hits the spot.
The smell- and taste of his Alpha, especially when musky after a long day of work, scratches that itch in his heat-fussy Omega hindbrain just right. So good- it makes him dizzy in the head, drunk on that scent.
Suckling at the head, he laves the flat of his tongue over the ridge on the crown. Digs the tip of his tongue into the foreskin, swirling round and round, slowly working it down the fat head of Deku's cock; before he sinks his mouth down on it- as far as he can physically manage, throat protesting, eyes teary, and hums- pleased with himself and his catch.
Katsuki feels the car swerve, then- abruptly pull over to the side of the road. Hears the crank of the handbrake, loud and aggressive, the truck's engine burbling to a stop, and blinks up through the corner of one eye- to look at his Alpha- who's staring right back at him.
They're in a forested area, no street lamps around. The only illumination- are the car's dashboard and headlights, casting Deku into sharp relief and making his furious expression look all the more terrifying. Tendons in his neck standing out. Giant chest heaving, pushing the buttons of his uniform's shirt to the absolute limit.
Yea, Deku's big mad, all right.
Katsuki swallows once, almost chokes, then pulls off Deku's dick slowly, slurping- loud and obnoxious the whole way off, before finally unlatching from the tip with a loud sucking pop, just to be nasty. Just to be a brat.
It's what does it.
Deku suddenly grabs him, yanks Katsuki over the center console, and doesn't even bother with taking the Omega's pants off. Just peels them down enough to pull Katsuki's ass out, before he already has his fat cockhead kiss him open, pussy so swollen- but soft and so fucking wet with his heat, that Deku easily pushes inside.
His cock is the kind that's too big to take without any prep, usually. But Katsuki's cunt is so hungry for him, starving- really, it practically sucks his dick right in to the hilt, barely any trouble at all.
Pushing Katsuki's hips away, then dragging them back, Deku pumps him over his dick like a rut-toy.
Fucks up into him and yanks him down again and again, hard enough to rattle Katsuki's teeth, bruise him up inside. Rocking the chassis and bumping Katsuki's ass into the steering wheel- that it honks the horn with every thrust.
It's getting too quickly too hot inside the truck, stuffy, the windows already fogging up as sweat runs down their bodies. Katsuki leans backwards- and reaches for the console to crank up the AC, when Deku grabs him, wild-eyed and frantic, like he thinks that- what?
Katsuki is gonna up and leave?
Like there could possibly be any other place in the world Katsuki'd rather be than right here?
He sighs- crazy with love- and reaches out to scratch his nails over Deku's head, the curve of his skull, where his hair is buzzed close to the scalp for the summer, soft and bristly against his palms. Enjoys the way it makes Deku shiver, relax into the touch, and loosen the bruising grip he has on Katsuki, rub his thumbs where he had grabbed the Omega a little too hard- in apology, before leaning in close, their noses bumping.
They kiss, all tongue. Mouthing at each others faces, slow and messy. Deku licks into the back of his throat, over the roof of Katsuki's mouth, making Katsuki's whole body tremble, tummy flutter, insides squeeze so tight- it punches a moan out of both of them.
Katsuki tries to spread his legs wider - but his jeans are in the way.
They really do seem to share a braincell sometimes, because he doesn't even have to say anything for Deku to grab and yank, the thick denim giving in with tearing seams as he tries to rip Katsuki out of his jeans. Pant legs catching on his fat boots as he pulls them down, and Deku almost loses his mind- when Katsuki gets up off his cock to go undo his shoe laces.
The Alpha grabs him around the middle and lifts him, KingKong carries him out the driver's side, stripping Katsuki's boots and pants and shirt off on the way- before sitting him onto a shoulder, like he doesn't weigh a thing, to nose into the crux of his thighs, inhaling deep, kissing and licking him right where Katsuki needs him the most; before Deku unceremoniously throws him into the backseat and climbs in after him.
Lies down over Katsuki, solid and immovable, waist spreading the Omega's thighs wide. Resting all his weight on top of him, pressing him flat into the firm seat cushions; trapping him in place, before pushing his cock back in one shove.
A notable thing about Katsuki- is that he has fucked his fair share of people, all kinds and from all over, but never has he come across anyone who fucks like Deku.
No one comes even close.
Deku fucks like heavy machinery. Like a pile driver, or- one of those giant drills they use to cut tunnels into mountains. Unrelenting, just keeps going, piston-piston-pistoning tirelessly. And he fucks good, like- real good. Rolling his hips, letting them swing, like he wants to scoop you out with every thrust.
Also, he's got a bomb dick. Just - huge. An overlarge spoon with which to furiously stir up Katsuki's little pudding cup.
God, fuck! He makes Katsuki sick in the damn head, go all nasty heat-horny brain. This Alpha has ruined him completely. There's no way Katsuki could ever fuck anyone else- ever again. The mere thought- laughable. Can't even imagine doing so. It wouldn't work with anyone else. Who could possibly compare?
He's wanton, desperate to feel him skin to skin, to touch him all over, clawing at the Alpha's uniform to get it off. Tears Deku's shirt right open, buttons popping, scattering all around them, and leans forward to bite into the Alpha's fat pecs, tugging his nipples between his teeth to make Deku squirm.
His fingers dig into Izuku's back, hips, the meat of his ass, pulling him in, urging him on. Needs to feel him deeper. Harder. More, more, more.
Deku finally bottoms out, dick punching all the way into the back, making the Omega sob on it. It hurts- fuck, it hurts it hurts- so fucking good~
Katsuki throws his head back and keens. Tries to brace himself against the car's window, fingers squeaking against the fogged-up glass, slipping, blindly searching for the handle, scrambling for something to hold on to- as he cums, jolts with a sharp gasp, orgasm wrecking through him so hard- he blacks out for a second there.
Comes back again- to the soft tug of Izuku's large hand through his sweat-damp hair, his lips against Katsuki's face, pressing kisses along his temple. The slow push and pull of the Alpha's massive cock working him through the aftershocks- that have Katsuki's legs jump and breath hitch with each drag.
Deku slows his pace to a deep, slow grind. ''I- i don't like when you go out like this. In heat..'' He mumbles, brows furrowed- and intently staring down at where his cock disappears into Katsuki's body. ''It makes me feel.. not good.''
Katsuki hums, and can't help the smile that tugs at the corners of his mouth. Thumbing circles into the muscles of Deku's neck, digging into the pressure points there to ease the tension in his big hunched shoulders. ''You know i can take care of myself.'' He soothes, running his hand along Izuku's sides, all soft caresses, fingers tracing lazy patterns. ''Been taking care of myself my whole life.''
And Deku just- kind of deflates at that, hips rolling to a stop. ''I know..'' He says. ''That's why.. i just..'' He sighs, and looks at Katsuki, a soul-deep stare, saying nothing for a good minute or so. Thankfully he doesn't look- upset, else Katsuki would have probably started fucking crying, but he looks.. frustrated. ''You have me now. No?'' Deku tries. ''You have me to take care of you now.'' He insists, firmer now.
Damn. So much for not crying.
Sometimes Katsuki just can't believe it. That someone like Izuku really is in his life; this impossibly cute guy, that fucks him so good- and treats him this well. Who takes care of him, and cares about him.
It's like a dream. More than Katsuki ever dared hope for having. More than someone like him probably deserves.
''Yea..'' Katsuki breathes - hiccuped, craning his neck forward to plant a kiss onto the furrow between the Alpha's brows, ''I just- still forget sometimes, that i'm not all alone anymore.'' -kisses his temple, then his eyelids, his freckled cheek, his cute little pout. ''That i am so lucky to have you now.''
His Alpha's face goes even cuter hearing that, screws it up all stupid, pouty. All red and shy.
This great big piece of man- all flustered, it's almost enough to make Katsuki cum again on the spot.
He loops his arms around Izuku's neck to press them flush against one another, hugging him tight.
Nuzzles against him, inhaling him deep, smelling Izuku right behind his ear, along the scent-gland there, where he smells all minty and musky and so so fucking good.
Sucks at his earlobe, softly tugging it between his teeth, just to hear him moan.
Katsuki just wants to bite into him, gobble him up, eat him alive. Wants the Alpha to crawl inside him- in turn, make home under Katsuki's skin and live there forever.
Brushing a few strands of hair from Deku's damp brow, his thumb tracing little hearts into the Alpha's freckled cheek, Katsuki wraps his legs- as best as he can- around Deku's waist, and starts humping up, fucking himself on the Alpha.
Deku groans low, head thrown back and eyes closed in pleasure, before he leans back to sit up on his haunches, rolls his hips- and starts grinding back, pushing himself in deep. Hands, so hot and heavy, gripping Katsuki by the waist to work his body around his cock.
''Yes! Please, more! Yes, don't stop, please don't stop, fuck me, fuckh me-h..'' Scratching his fingers along Deku's flexing sweat-slick abs, the little bit of pudge on his lower tummy that makes Katsuki fucking feral, then- through the trail of hair beneath his navel- leading to the base of his cock- already swelling with the promise of a knot. ''Wan'it. I want it, gimme,'' He moans, needy and desperate for it.
Puts one of his own hands ontop his stomach, to feel the bulge Deku's dick makes in it, and presses down on it. The ache growing in his gut crests, pulling tight behind his belly button, curling his toes.
Katsuki's whole body seizes tight as he cums, but Deku- with a grunt- just keeps pushing through the resistence of his clenching muscles.
''Clingin' to me so good.'' The Alpha slurs out, panting. ''Like yer made jus' for'me. Just like- i was made for you..''
Katsuki loves to hear it, nods his head, agreeing with little ''Uh-huh''s, while throwing his hips back onto Deku's every thrust.
Blinks- and suddenly finds himself folded in half, Deku's weight atop him crushing him flat into the seat cushions- as he drives in hard, pummeling him with deep thrusts that have Katsuki forget how to breathe. Car axle rocking so hard it's a miracle the damn truck doesn't just flip over.
Deku's rough thumb flicks over Katsuki's 'press me' button, making him light up, do a little song and dance.
A whisper- to a whimper- to a shout- to a scream, and the Alpha at last stretches him over his knot.
Thighs trembling, Katsuki whines, breathless, pushing back into the harsh press of it- to feel it even more. The painful twinge deep in his belly from being stuffed too full, pried open this deep inside, stretched so wide on that knob. Pussy burning so damn good- as Deku grinds his hips into him hard and deep, make sure he packs it all in.
Izuku licks into his open mouth to suck on his tongue, and Katsuki wraps his arms tight around him, hugging and holding him close.
It takes a while before Deku can pull out again. The drag of it- against his rubbed raw insides- almost enough to make Katsuki cum once more.
Still high off the feel good hormones from their tie, he dazedly blinks down at the Alpha's cock, gleaming with slick and cum- like glaze on some obscene pastry, making his mouth water. His heat-silly brain screams for more, still hungry, ravenous, but Katsuki's body probably wouldn't survive another round. Feels like tenderized meat, so sore and throbbing he can't close his legs, hip joints aching, his whole damn crotch on fire.
Deku rumbles, a low pleased purr deep in his chest- as he holds Katsuki's legs by the crook of the knees and spreads him wide, then leans in close- to softly blow on it. Making Katsuki gasp, whine, and squirm in his hold, trembling helplessly.
Even that is too much right now.
The Alpha shushes him, then does it again, before suddenly pressing his lips flat against Katsuki's pussy - blowing a raspberry onto it.
Katsuki shrieks, starts kicking.
Deku just grabs his thighs harder, laughs, and does it again; the wet fart sound it makes- as funny as it is fucking nasty.
Izuku eventually tires of his bullying and he moves back up toward Katsuki's face, pressing wet kisses against his mouth that taste like the sloppy mess between his thighs, before climbing out the truck, now buck ass naked, striding with the kind of swagger all Alpha's get after plunging in some pussy.
Katsuki huffs in irritation at the display, and throws his legs up in a V, knees straight, to stretch his aching muscles and let the breeze cool his burning crotch.
The radio comes to life, playing some random local station's late night assortment of early 2000's dad-rock on low, almost drowned out by the mechanical whir of Deku rolling all the windows down. It prompts Katsuki to inhale deep, nose instantly wrinkling.
Cum and slick and sweat, the truck practically reeks with it. Won't get it out of the upholstery for a good while even with all the windows down.
Deku returns to climb back into the backseat with him, manhandling Katsuki to arrange them both in the crammed space.
Katsuki pinches him in the ass, and Deku retaliates with smacking his in turn- hard enough to leave it smarting. Then does it again- for good measure, making Katsuki yelp and jump.
The Alpha breathes out a laugh from his nose and kisses Katsuki's cheek, radiating pure ease and contentment, his sour mood from earlier all but forgotten, and wraps his dumb large arms around him and squeezes, tight enough to make Katsuki wheeze a squealing sound, like a squeaky rubber chicken being slowly wrung out.
His bones ache, well used and well loved, and as he's laying there tired and sated and held tight, Katsuki makes a mental note to buy his Alpha something nice with the tips he's gotten tonight.
