Katsuki is out on patrol with Deku when he gets the call, during a rare down time they are able to take a small break away from prying eyes. It comes through his comms ear piece. EMERGENCY CALL FROM CHARGEBOLT, the robotic voice chimes in his ear.
He quickly taps the button to accept. "What do you want?"
He hears frantic whispers argue back and forth, and then Kaminari squeaks into his ear. "Ahh, you're not going to like this."
He pinches the bridge of his nose. "Spit it out, I don't have all day." A smack echoes over the call, and he hears Kaminari yelp in pain, catching a hushed, 'Out with it, moron!'.
Kaminari sucks in a deep breath. "Hitoshi got hit with a quirk, and now he's kinda rut feral."
"What the fuck? How?" Hitoshi smelled perfectly normal this morning, and his ruts always took forever to build up. They weren't sudden like this.
"I told you, it was a nasty quirk this villain had!"
"Damn it, where is he? I'll drag him home. Deku can give the agency a heads up."
"Kacchan," Kaminari speaks hesitantly. "It's gonna take more than that."
Tetsu's voice belts over the phone, "He's gonna pin you down and knot you the second he smells you!"
"It's that bad?" He asks, doubtful.
"Yeah, dude!" Kaminari screeches. "I was told to call you and ask if you want us to tranq him or not."
"You're not doing that," he hisses. Tranqing feral alphas and omegas fucked their shit up for months, he isn't letting that happen to Hitoshi.
"Then you're gonna have to let him fuck you to calm him down enough to get him home.”
"Fuck!" He rubs his thumb and index finger into his eyes. "Send me the location." He hangs up and Deku practically pounces.
"What's wrong?"
"I gotta..." heat blooms across his face. "Hitoshi's got thrown into rut, I have to go help him."
"Oh! Do you need help?"
Katsuki forces himself to hold Deku’s gaze. "You can't help with the way I'm going to do it." He waits for the seconds it takes for understanding to dawn him, knows it clicks when Deku flushes beet red and sputters. Hitoshi will likely want to tear Deku apart if shows up too.
The location is a mall parking lot. That's fucking great. When he arrives, there's a large group of civilians milling about. Katsuki knows they are leeches trying to get a glimpse of a feral alpha hero, and it pisses him off. Hitoshi isn't a side show attraction. Later on, once they are back in their nest, Katsuki knows that he's going to be consoling him. The public is already weary of him with his quirk, on top of the ability to give alpha commands, and Hitoshi is going to be crushed that this is going to be one more thing to the list.
He forces his way through the crowd, uncaring of the annoyed responses. Marching up to the huddle of cops and heroes, Kaminari catches his eye, relief flooding over him.
"See! I told you I knew his mate." He grins at the detective while slapping a hand on Katsuki’s shoulder.
The guy manages to wipe the surprise off his face quickly, and addresses him. "You're positive you don't want us to sedate him?"
"You're not touching him with that shit." He moves to step toward him, and Kaminari tugs him back.
"Come one man, now's not the time."
After shooting the cop one final glare, he reaches up to rip the patches off his neck. "Where is he?"
"They've got him secluded a little bit over to the left. He's constrained by Sero’s tape right now."
"That's working?" He raises and eyebrow in doubt.
"Only after the other alphas cleared out, and I can tell he's barely hanging in there."
Pride wells up in his chest. Of course, Hitoshi has enough self control to wait for Katsuki. Not every alpha does, but his alpha is one of the best.
Katsuki sees him first. He's crouched on the group, chest heaving with threatening growls warning off alphas. The tension in is body is stark, and Katsuki feels the urge to scent his neck and purr him down from whatever cliff he is treading.
"I'll try to keep people away," Kaminari mutters. "But you know how it is." He shrugs sheepishly.
As fucking inconvenient as it is, Katsuki understands. It isn't unheard of for an omega to be knotted by a feral alpha in public, but it doesn't happen often. Much less two well known heroes.
He's going to Hitoshi so much shit. "I fucking get it, Sparky. It's whatever."
Hitoshi's head snaps up at Katsuki’s voice, and the possessive growl that accompanies the action has him slicking up. The tape tears to shreds, and he's reminded of how fast Hitoshi is by the short time it takes him to reach him. They tumble to the ground, and Katsuki’s head is yanked back to allow him access to his throat. Hitoshi still has his voice modular on, digging into his skin as he desperately tries to get to his scent glands. A petulant whine pierces his ears.
"Stupid alpha," he groans.
Wedging his arms between them, he unhooks the mask and tosses it to the side. Hitoshi grunts his approval and dives back in, licking hot streaks over both glands. He sucks and scraps fangs over them before soothing them with his tongue, repeating the process over and over. Once they are raw and swollen, Katsuki attempts to yank him back, holding back a whimper because it's starting to hurt. Hitoshi snarls and pins his wrist to the ground.
"Not done yet, omega." His voice is rough and husky, the one Katsuki only hears in the privacy of the nest.
Shit. It does things to him, and he wants to sink into the familiarity of it, but the noise of their audience distracts him. He's already wet, the aggressive display paired with the intense rut scent makes heat pool in his stomach. Katsuki knows Hitoshi smells it. One strong arm pries his thigh to the side, and Hitoshi grinds into his cunt. Katsuki chokes back a moan, focusing on the rocks digging into his back to keep a grip on his bearings.
Hitoshi bites his collar bone. "Wanna hear you, omega. You always make the prettiest noises." Hitoshi rips the front of his shirt apart and clamps his teeth around a nipple to pull on it. Katsuki sucks in air with his nose, and keens low in his throat. Hitoshi croons back at him, bruising and leaving teeth indentations around the nipple before brutalizing the next. He's digging his nails into Hitoshi's shoulders, trying keep his noise level low so he doesn't give the shitty extras more of a show. The hard cock rocking into his pulsing cunt doesn't help, nor the way Hitoshi angles his pelvis to trap his own cock between them. Shit, he's close, the pressure in his abdomen winding tighter and tighter. He's gonna kill Hitoshi for this.
"Let go, pretty omega," he taunts between nipping his earlobe. "You're almost there, I can smell it. Show them how filthy you are, that you don't even need a cock fucking your sloppy hole to cum."
"Fuck," he whimpers, attempting to crawl away, but Hitoshi grinds harder.
"Be a good little omega. Cum for me, make your alpha happy." His hot breath dances across his skin and Katsuki snaps, back arching as he moans loudly. Electricity sparks across his skin, and the heated pressure from his abdomen explodes. Katsuki brings his knees higher up Hitoshi's waist from tensing his body. Between the gush of slick and cum, when the alpha ruts into him, his boxers shifts uncomfortably against him. Hitoshi digs his nails into his chin to jerk his face close, and crashes his mouth onto his. Their teeth clack, and Katsuki is forced to swallow a litany of grunts and growls from him.
"Good boy," Hitoshi hums against his lips, flicking his tongue across them. He hears tearing fabric and suddenly a breeze hits his drenched cunt. Two fingers tease his folds, using his slick to knead up and down them. Katsuki spreads his thighs and lifts his hips to encourage them to go inside, and Hitoshi chuckles darkly next to his ear.
"Look at you, desperate to be fucked open by my hand. You can't wait for people to watch you be stretched wide around me knot. Show everyone what a perfect omega you are, that your cunt loves being a glorified toy for me." He whines, burrowing his nose into Hitoshi's damp scent patch. "Let them hear you scream, pretty omega, they want to see how much of a whore you are for me."
His insides are boiling from arousal and shame, mortified everyone can see, but Hitoshi's right. Katsuki loves the feeling of his knot, and the rut pheromones are intoxicating.
"Please," he murmurs into his neck.
"Louder, my needy little omega. You have to speak up when you use your words." Hitoshi forces his head back by the scruff of his neck and pins him down by the throat. The pressure doesn't hurt, but it's intimidating and slightly threatening. Hitoshi rarely falls this deep into rut, and having his imposing frame looming over him makes his omega whine and roll over. Normally, he'd push back, but that little game is for them, in the privacy of the den. These extras don't get to witness it.
Raising his voice, "Please?"
The responding grin is wild, and his pupil consumed eyes flash. "Good omega."
Fingers thrust inside him, and Katsuki arches his back in surprise. He's attuned to his body, has learned every little spot to drive him crazy, and Hitoshi immediately curls them to knead his nerves.
"Toshi," he groans, grinding his hips onto his hand. He's hard again, flushed and begging for friction. "Touch me, please."
"I am," he huffs with amusement, flexing his fingers curled around his neck for emphasis. "Do you mean your cock?" Hitoshi bites at his cheek. "If you can cum on just my fingers, you can touch yourself while I'm fucking you open with my knot."
Katsuki groans in frustration, and increases the pace of his hips, ignoring the wet sound of Hitoshi's fingers sliding in and out of his cunt.
"That's it, omega. Keep going."
Buzzing fills his ears, waves of vibrations swell under his skin and in his nerves. Hitoshi's hand is a heavy weight on throat, keeping him centered. He's gasping and releasing broken whines as his thighs involuntarily twitch and shake. The fingers inside him stroke and grind. He sobs as another orgasm rips through him, covering Hitoshi's hand with slick and cum. Static settles over his mind and skin, and he's painfully aware that his dick is still hard.
His breaths are ragged as he watches as Hitoshi lifts his finger to his mouth to lick it clean. The next kiss is less teeth, but still violent, and Katsuki tastes himself, and it's exhilarating. The smell of Hitoshi surrounds him, and the rest of the world fades into the background. His tongue invades his mouth, licking every surface to claim every part of Katsuki. Abruptly, he's flipped around, and he mourns the lose of the kiss. A palm firmly presses between his shoulder blades, and Katsuki easily drops his chest to the concrete. He's thankful for the pants saving his knees.
Hitoshi's croon of approval sounds behind him. It makes him melt, burying his face into his forearms. He hears Hitoshi shifting before thumbing his cunt open, it's sticky and resists being teased apart.
"Do you think cameras can reach us? If I move a bit to the left, could they focus enough to get a picture?"
The thought's horrifying, he can't imagine his pussy being plastered all over the internet. It's fucking nice, but he doesn't want every goddamn person seeing it. Regardless, he shakes his hips to entice Hitoshi into finally putting his dick inside him. He's not in heat, not yet anyway, but he's horny as fuck now. Plus, the faster Hitoshi knots him, the sooner they can go the fuck home. The pad of his finger dips into his cunt and teases his ass.
"We can let everyone see how you're a slut that also let's me knot you here."
"Stupid, alpha. We don't have the lube or time for that." He glares over his shoulder to catch him pouting.
Luckily, he doesn't argue, and moves to undo his pants - why does only Katsuki’s clothes have to be torn to shreds? When Hitoshi's cock strings free, he salivates. It's red and angry, knot already forming, and Katsuki wishes they had the luxury of time to allow him to lap up the pre dripping from the head.
He smirks at Hitoshi and presses more of his chest to the ground, dropping his thighs impossibly wide. "Come on, alpha."
His cunt is soaking wet, and Hitoshi's possessive growl makes him clench in anticipation. Nails pierce his skin as his hips are repositioned. There's no warning before the tip of his cock breeches him, thrusting in hard without pause until the knot catches on his rim. He's being split open as Hitoshi carves a space inside him. The stretch aches, nearly burns him alive, and Katsuki drives himself back to help work the knot further. Hitoshi's grunts and moans rival his own frenzied noises. The rut induced pace is brutal, punching his breath out. The knot pops in and out as he works it into his cunt, each thrust easing more in. His world is reduced to the gravel underneath his forearms, the biting grip on his waist, and the cock fucking him. Humming pulses from his abdomen echo throughout his stomach and thighs.
"Touch yourself, omega," he commands in a gruff voice.
Katsuki rushes to obey, fisting his cock in his hand to jerk himself in time with Hitoshi. It doesn't take long, a few strokes and his thumb pressing beneath the head, and he cumming onto the parking lot. He clamps down around Hitoshi's cock, squirting around him, and he curses above him. Tightening his hold, his movements stutter erratically as he grinds harder to push his knot inside. Once it finally pops through, aided by all the fluids, Katsuki mewls and tenses. He feels the large quantity of cum filling him, more than usual, even during ruts in the past. The preening of his omega in the back of his mind reminds him of his impending heat that this whole tryst has triggered. Hopefully it won't last as long as normal.
The tension bleeds out of Hitoshi, and he drops his chest across his back, nuzzling under his jaw to scent him. It's easy to match his breathing, knows it always helps Hitoshi come down during rut. The weight on top of him shifts, as if to shield him from view as much as possible. It appears that normal Hitoshi doesn't have the same sentiment as rut Hitoshi in the desire to display Katsuki to the world.
When he speaks, it's raspy, but not the same deep tone. "Hey."
Katsuki snorts. "Nice of you to join us."
He groans with embarrassment. "Shut up."
"Do you at least feel better?"
There's a pause, like he's assessing himself. "Yeah. Definitely still in rut, but shouldn't be a problem getting home now."
"I'll make Kaminari bring us supplies, we aren't stocked up for a heat share."
"Sorry," he responds sheepishly.
"It's whatever."
"PR is going to pissed at us."
Katsuki shrugs. "This actually might be better than a whole event to announce our relationship."
"Yeah, spreading your legs for me is a lot easier than a press conference."
"Fuck off," he hissed. "I hate you."
Hitoshi snickers, wrapping an arm around his waist to press him closer. "What are the odds of a video of us is already on the web?"
"There was probably half a dozen videos with different angles streaming it live."
"You wanna jerk off together to them later?"
