Misunderstandings

So what if Kirishima hadn’t picked him up from the office in a week? Or come by his apartment? Or barely been in the office?

Bakugou Katsuki didn’t care.

He’s busy.

And Kiri-no-Red Riot was busy. He’d just hit 4 for the first time on the hero charts and a jump like that is bound to cause some extra work.

Besides, Baku-er-Ground Zero was busy too. 

Real busy. Like *so* fuckin’ busy.

He didn’t even have time to be pissed off about the fact that his boyfriend hadn’t been around. He was fine. It wasn’t like the whole point of having the agency together was to see each other every day. That would be stupid. So stupid. 

He didn’t miss him.

Or his stupid sunshiney face or loud ass clothes. 

“Tch… What a fuckin’ asshole.” He grabbed his bag and headed for the elevator, scowl on his face. “Can’t believe he doesn’t even call.” He jabbed the button for the parking garage. “I’ll show him.”

He adjusted the bag on his shoulder and stuffed his hands in his pockets as the doors opened. “I’ll just go by the bakery he likes and buy a-no-4 fuckin’ orders of those stupid cakes and then-”

“Ground Zero.”

The hands were on him before the blond had a chance to understand. Big, hot, calloused hands, encircling his waist, groping his chest, his ass. “Ah! Fuck! K-Kiri-”

“You’re comin’ with me,” the voice growled in his ear. Kirishima grabbed him by the wrist, “Now.” And pulled him toward his car. 

“Wha-What the fuck?” Bakugou strained in the grip, tugging in vain. “You can’t just show up in the middle of the goddamn night and-and-”

Kirishima threw the door open, shoved him into the passenger seat.”Buckle up.”

“Listen here you…” Bakugou’s breath caught, the words died on his tongue. 

Never. 

Ever.

Not once in the 7 years he’d known Kirishima Eijirou had he seen him look like this.

The dim lights of the garage wrapped his handsome face in shadow, but still.. His eyes were clear, damn near gleaming in the low light, his plush lips twisted in a snarl. 

Holy fuck.

Bakugou watched him stalk around the front of the car before peeling out of the lot and damn near into the side of a truck as he skidded into traffic. Bakugou stared at his boyfriend, eyes wide, heart pounding and vaguely wondered if he should be as turned on as he was right now.

Especially since Kiri had a fuckin’ white knuckle death grip on the steering wheel and literally chewing jolly ranchers like they weren’t teeth murdering candy rocks.

“Ki-” Bakugou cleared his throat, shifted in his seat “Kirishima”

Predatory eyes cut to his in the rearview mirror, another handful of fruity candy stone crushed.

“Where are you takin’ me?” It came out wobbly, nervous. Bakugou clutched his bag to his chest. “My apartment’s the other way.”

“Not goin’ there.” CRUNCH

.

“Then-” a horn blared as they merged, cutting off some speeder, only for the redhead to hit the gas and leave them in the dust. 

Shit. Wow.

Kirishima was the careful driver,he’s never-

“Takin’ you somewhere else.”

Bakugou swallowed hard, eyes drifting across the bay, to the gaping black monstrosities that used to manufacture war machines.

He rode in silence, endless possibilities playing and replaying themselves through his mind as they wove through traffic toward those abandoned relics of violence.

Pulling up in the gravel lot, through a broken gate, Bakugou’s stomach tightened. What was happening? Why were they here? He scanned the empty lot, broken glass catching the light of the city across the bay. It was beautiful in a post-apocalyptic sort of way.

His eyes lingered on the inky waters before drifting to Kirishima who looked as though he were on the verge of screaming.

The blond watched warily as the redhead shifted into park and killed the engine, chest rising and falling in shallow rapid breaths, hands still strangling the wheel. “I can’t take it anymore,” Kirishima whispered, breathless, desperate, gaze falling downward. 

Fucking fuck!

What was happening? Was he angry? Is that why he hadn’t been around? Had he finally grown tired of Katsuki and his-his-Just-just-HIM?

Bakugou’s stomach twisted, panic tingling at the base of his spine.“Eiji-”

But the young hero was out of the car and tearing open Katsuki’s door before the blond could finish the thought. Stunned, he let Eijirou pull him up and out of the passenger “Ei!” he panted, falling into the larger man’s chest “We can- Ah! Fuck!”

He scrambled to grab at Eijirou’s broad shoulders as the redhead hoisted him up by his thighs and dropped him onto the hood of the car. “What are-”

Sugar.

He tasted like sugar. Sweet and tangy with an unnamable artificial fruit punch flavor riding on the tip of his tongue. A tongue that was now shoving past Bakugou’s lips. The blond moaned despite his confusion, fisting his hands in loose red hair.

“I’m sorry,” Kirishima licked his lips, leaned his forehead against Bakugou’s. “I know you’ve been busy and I-” He kissed Bakugou again, hard and desperate, crushing the blond against him. “I tried, Kat.” He traced the column of Bakugou’s neck with his tongue, his teeth.

“I tried to wait, to hold back, but-” He jerked back suddenly tearing away his shirt. "I *need* you."

CWs: Bottom Kiri but like... Power Bottom Kiri, Semi Public Sex

Kirishima bit his lip, ruby eyes narrowed, dangerous. “Will you?” He leaned in, tracing the tip of his tongue along the seam of Bakugou’s lips. “Will you give me what I need?”

And looking up at this mountain of a man, this unbreakable wall of muscle and stamina, this apex fucking predator, Bakugou’s head spun. His eyes fluttered close, his heart stuttered. “God damn,” he huffed, smile tugging at his lips.”Gimme that ass-”

He hauled Kirishima down, mouths hovering “-daddy.” Before tugging back and licking a long, hot stripe up Kirishima’s throat. 

The hero trembled, a growl rose from his chest and then he was spinning around in Bakugou’s arms;

pressing that full, firm ass against Bakugou’s pre dampened briefs. Twining their hands together, he ran the blond’s hands up his scarred abs, over the solid mounds of his pierced pecs, before letting his lover hook his arms around his shoulders.

Then he hooked his thumbs in the waist of his official Ground Zero sweat pants and peeled the black fleece over his bare ass as he bent forward.

Bakugou ran his tongue along the points of his teeth as he took in the sight before him, eyes lingering on the flash of red nestled between those thick cheeks.

Gripping a cheek in each hand, Bakugou kneaded the tan flesh, letting out a hiss of appreciation as he spread Kirishima wide. “Fuck,” he murmured, letting go of the right just to run his fingers along the end of the plug.

“K-Kat!” A wave of hardening rose up the ridge of his spine like waves in the bay as Bakugou pulled the toy free. “MMmm Fuck!”

Bakugou tossed the plug over his shoulder and spread Kirishima wide again, groaning while he watched the city lights sparkle in the lube that trickled down his boyfriend’s taint. 

How the hell did he get so lucky?

Kirishima’s hole fluttered, the redhead whined and Bakugou couldn’t wait any longer. Pulling his cock free, he slid the tip in.

Then out.

Teasing.

But Kirishima was in no mood to be teased.

Rolling back on his heels, Kirishima took what he needed as he impaled himself on his boyfriend’s cock. Twin moans echoed off the dilapidated concrete. “Ah! Nnnggg! Fuck!” Bakugou tightened his hold on Kirishima’s shoulders, pulling the redhead up into a sinful arch.

“K-KatsukI! Kat! God! Y-yes!” Kirishima used the leverage of the pull to slam himself back, riding Bakugou’s perfect, pierced cock.
“That’s it, daddy,” the blond growled in Kirishima’s ear. “Hah! Take what you need.”

He thrust up into the hero’s exquisite heat, growling and matching his desperate boyfriend’s urgent pace. “Ah! Yeah! Ei! MMmm! Take it! Take it all, Ei!” He knew he was babbling, he didn’t care. He felt light, warm, almost drunk on the moment.

On the slide of his dick in Kirishima’s body, on the pillowy, slick heat around him, on the whines and cries and chant of his name falling from the young pro’s spit wet lips as they fucked hard and fast on the hood of a sports car in an abandoned lot.

On the fact that despite his earlier fears and misgivings, he was just as desperate, just as relieved as Kirishima to be together right now.
On the fact that he loved this man so goddamn completely.

The telltale shudder of Kirishima’s breath, the tightening of his shoulders, the squeeze of his rim, meant he was reaching his edge. Shifting his hold, Bakugou thrust harder, faster, goading the pooling desire to break free from its dam and send his Kiri over the edge.

“God, Ei,” he grit “You’re so-Ah! I-Fuck!”
“Yeahyeahyeahyeah!” Kirishima angled his head back, mouth parted, “K-Kat!”
Their mouths hovered, sharing hot breaths and almost kisses and then…
“I missed you, Ei.”
The wire snapped.

Kirishima came untouched, heavy cock painting the gravel with his release. His tight hole clenched and squeezed, milking his lover until he too fell into ecstasy.

**********************

Wrapped in Kirishima’s arms and covered by the “emergency blanket”, Bakugou stared out over the bay. “So why here?” He snuggled closer, adjusting his legs that dangled over the spoiler.

“Oh! I saw this place while on patrol with Suneater. I-uh-” He ran his hand along Bakugou’s ribs. “I thought you’d like the view.”
“Idiot.” He turned away to hide his smile.
“And uh-” Kirishima shifted, pulling Bakugou closer, tilting his face up. “I wanted to ask you somethin’”

All of the blond’s earlier anxieties returned, sitting like a stone in his stomach. “What?”
Kirishima rolled his lips, inhaled deeply. “I know you didn’t wanna live together since we’d be workin’ together, but-” He ran his thumb across Bakugou’s cheek. “-What I mean is-”
“Yes.”

Kirishima stared, eyes wide and blinking. A slow smile grew to blinding proportions as realization dawned. “Really?”
Bakugou cut his eyes away, heat burning in his cheeks. God. If the idiot had a tail, he’d be wagging it.

“I said ‘yes’, didn’t I?” He pressed his lips together and peeked back up at Kirishima. “But you’re moving into my place. It’s better. And all my shit’s there. Besides-” he huffed.

“-I can’t have you goin’ all Feral Riot on me again.” He cleared his throat. “I mean… Unless ya wanna.”
And he'd never have to "not miss" Kirishima again.
