Heavy breaths mingle and Kirishima surged forward again to capture Bakugou’s lips in a deep kiss. Hands reach up, one on his jaw, and the other burying itself in blond hair, gripping hard and pushing Bakugou’s head closer to his own.
“F-fuck you’re aggressive.” Bakugou breathes out as he pushes back to gulp in some air.
“Because it’s you.” Kirishima licks his lips before jumping back in, deciding that three seconds was enough for Bakugou to catch his breath.
They are in pro hero Ground Zero’s apartment on the hero’s day off. Said hero was being pressed down into his sheets by his very large, very buff, pro hero boyfriend, Red Riot.
“You’re off tomorrow too, right?” Kirishima asks, kissing down his neck.
Bakugou tilts his head to the side, exposing more of his neck for Kirishima to kiss and nip.
“Yeah why?”
Kirishima nips the bottom of his jaw and grins. “I’m gonna fuck you until you can’t walk.” And continues kissing down Bakugou’s chest.
The blond idly wonders if Kirishima can feel his heart beating out of his chest. He smirks and bears his teeth. “That’s a pretty hefty threat, think you could actually make good on it?”
Kirishima moves to sit on his knees and rips his shirt off, grinning down at Bakugou. This forces Bakugou to crane his neck back to meet the red eyes staring down at him.
“You better believe it.” And Kirishima tugs at Bakugou’s tank top, pulling it over his head and carelessly throwing it onto the floor.
“Hngg,” Bakugou lets out a strangled moan and Kirishima licks his right nipple while his hands travel slowly down his chest, once they reach the hem of his sweatpants he tucks his hands into the bands of his pants and underwear and swiftly pulls them both down.
Bakugou is at half-mast and with a few rough pumps he’s fully hard within seconds. A very fun fact about Bakugou is that when it comes to fucking, especially Kirishima fucking him, he has barely any patience for foreplay. Kirishima spreads his legs wider and leans his head in to swipe his tongue over the puckered pink rim of Bakugou’s asshole.
He cringes slightly at the artificial flavor of the strawberry lube already coating the hole, a telltale sign that Bakugou had already fingered himself open before Kirishima even arrived to his apartment.
This makes Kirishima crack a grin, “you’re so good for me.”He says before he dives back between his cheeks and plunges his tongue inside coating the inner walls with saliva alongside the lube.
Bakugou chokes and fists his hands in Kirishima’s red locks. “Fucking get on with it already,” He hisses out, but contrary to his words he grinds down onto the tongue.
Despite the pulling on his hair Kirishima doesn’t stop and grabs Bakugou’s ass cheeks and forces his hips closer to his face so that he could lick deeper inside the hole, going as far as his tongue would let him; he’s huffing hot breaths between his legs and at this point Bakugou is so hard that precum is sliding down his shaft.
Taking his tongue back Kirishima puckers his lips against the rim and kisses it as if it were lips and buries his face into the feeling, sliding his head around between the cheeks and sporadically going from licking the hole to opening his mouth and letting his tongue run over it and slide all around Bakugou’s balls.
“K-kirish-m- Fuck! God you’re so f-fucking gross.” Bakugou’s grip in his hair gets tighter and Kirishima decides to finally be a nice boyfriend and sticks two fingers inside the hole, quickly.scissoring them to check if Bakugou was loose enough to take his large cock.
“I’m ready- just fuck me you asshole.” Bakugou growls out, aggressive in every aspect of his life, even in the bedroom.
“Alright alright, impatient.” Kirishima laughs and leans down to kiss Bakugou. The second their lips meet he slowly pushes his dick inside until he is fully seated. Bakugou breaks the kiss with a groan and digs his nails into Kirishima’s back at the same time that Kirishima lets out a strangled moan.
Having ignored his own pleasure for so long and then suddenly being enveloped in such a tight warm heat makes Kirishima moan brokenly into Bakugou’s mouth, resuming the kiss.
He pulls back a little before slamming back in with Bakugou’s nails dragging down his back.
“Fuck you feel good,” he pulls back and slams in again, “Fuck, Katsuki.” He slams in so hard that the bedframe hits the wall with a sharp ‘SMACK’.
Bakugou is shivering on the bed. “Ei-eij-“ He tries to whimper out but before he can even utter his lover’s full name Kirishima leans his head on his shoulder and starts slamming into the hole with abandon.
“Urg, f-fuck Katsuki, fuc-, you won’t be able to walk for weeks by the time I’m done with you.”
Bakugou honestly hopes so, he hasn’t had any intimate time with Kirishima in weeks with their conflicting hero schedules and honestly he had missed the feeling of being plugged up with something so big and warm that it was hard to even form thoughts. And so he doesn’t. Bakugou whimpers and mewls sweetly and can only hold onto Kirishima’s shoulders and the bigger man doesn’t even take a second to stop his onslaught on Bakugou’s sensitive hole.
This whole time his dick was ignored but Bakugou honestly felt that he could cum just from the brutal pounding.
“K-kiri- Ej-eijii- Ah! I’m- I’m gonna-,” It was difficult to even get these words out but Kirishima knew what Bakugou was trying to say and pounded even harder.
“That’s it baby, fuck, cum for me.”
With an arched back and a scream of “EIJIROU!” Bakugou did just that, his cum flying out from his flushed cock and splashing down onto his chest, a few blobs landing on his chin and Kirishima’s own taught abs.
Kirishima slowed his thrusts down and leaned back to look at Bakugou under him, flushed red from his chest to his face, covered in a few stripes of cum, panting heavily, and eyes bleary.
“Shit Katsuki you look good like this,” Kirishima smirked and slammed his hands down beside the blonde’s head and continued with his brutal pace from before.
Bakugou howled in pain, overstimulated from the orgasm he just had ten seconds ago.
“I’m gonna cover you in my cum.” Kirishima breaths these word’s into Bakugou’s ear and Bakugou can cry from how turned on he is.
He manages to mewl out, “Please” and Kirishima roughly pulls out of his hole to kneel over him and jerk off while looking down at him.
Bakugou averts his eyes feeling embarrassed but honestly that only adds to the image and Kirishima finishes with a curse and streams of cum fly onto Bakugou’s face and down his chest.
He grimaces at the feeling but Kirishima leans down and starts rubbing his chest. At first it feels comforting and it helps Bakugou catch his breath...until he realizes what he’s doing.
Bakugou jerks to the side violently.
“WHAT THE FUCK ARE YOU DOING, BASTARD?!?” face even redder than before.
Kirishima doesn’t even have the decency to look embarrassed and doesn’t even stop rubbing the cum into Bakugou’s chest.
He sits up and beckons Bakugou over, who looks skeptical at best - disgusted at worst.
Hesitantly the blond crawls over and Kirishima guides him onto his stomach and Kirishima immediately latches onto his plump ass and gives the right cheek a loud smack!
“HEY! What the f—aa-aahh, hngg.” Bakugou’s indigent yell is cut off by three smacks in quick succession to the same spot and Kirishima grabs the cheeks and jiggles it in his hand.
He dips a finger into the hole and wiggles it around. “You know, I said I wanted you covered in my cum but I think I want to fill you with it too,” and before Bakugou can turn around and call him a perverted bastard Kirishima is once again fully sheathed in his ass.
With a fist in his hair he pushes Bakugou’s face into the bed, effectively rubbing him into the cum that’s on his face.
“S-stop it’s gross-“ But his demands went ignored as Kirishima laughed and rubbed his face in the cum harder and with another smack to his plump ass Kirishima is back to pounding into his ass.
“I’m st-still sensitive, you fuck, stop it!” Bakugou grits out, his still soft dick rubbing into the sheets and the thrust force his hips down and Kirishima is literally fucking him into the mattress.
Kirishima, the bastard, has the audacity to huff a little in annoyance before pulling out and flipping Bakugou over, now straddling the hero’s waist.
“Fine I’ll find something else to do.” And shoves his fingers into Bakugou’s mouth.
An angry “HAH?!?!” is all he can say before fingers from both hands rub along his tongue and stretch his mouth open, exposing more teeth and cheek than usual.
Kirishima licks his lips in anticipation. “Get on the floor, on your knees.”
Normally Bakugou would scream at being ordered around but Bakugou got the feeling that it was either this or in his sensitive ass again so he shuffles down off the bed and onto his knees on the floor.
Kirishima takes a seat at the edge of the bed and spreads his legs wide looking down at the blond. Bakugou’s face and chest is still smeared with their cum and Kirishima can’t even think about holding off any more and drags Bakugou’s face over to his crotch by the back of his head.
Bakugou takes the hints and starts to try to swallow the large cock in front of him, only managing to swallow down half way before Kirishima is groaning and bucking up into his mouth. When the dick hits the back of his throat and he gags he can’t even pull away because Kirishima’s big hands and holding his head in place and he fucks up into his mouth.
“hah, Katsuki, aah, you’re so good, ah, you feel so good, ah, ah, ah.” Each moan is punctuated with a thrust into his throat and Bakugou feels his eyes filling up with tears, they spill down his cheeks once Kirishima is fully pushing his head down onto his cock, making it impossible to breathe.
“Fuck!” Kirishima lets go with a laugh as Bakugou is reeling backwards coughing, trying to catch his breath. “You alright?”
“You trying to fucking kill me?” He pants out, wiping at his mouth that had drool sliding down his chin.
“You can’t take it?” Kirishima challenges and, like a fool, Bakugou rises to the bait and stuffs the entire cock back into his mouth.
“ACHK!” Kirishima chokes and Bakugou is stuffing his mouth with him and bobbing his head up and down the long thick shaft.
Bakugou’s hands reach up and start twisting at the base as his mouth goes down on the upper half of Kirishima’s cock. Obscene slurping and sucking noises fill the room as he fists and sucks at the cock in his mouth.
Right before Kirishima is about to cum he roughly grips Katsuki by the back of his head, rips him off of his cock, and with a few rough pumps he is cumming onto Katsuki’s face and down his naked chest where bits of cum from before had dried or were still sliding down. Kirishima took a minute to appreciate the full sight.
Bakugou’s head was tilted back by the hand gripped in his hair, face flushed a bright red from lack of oxygen, chest heaving heavily, tears tracks down his cheek, now covered in cum, drool slipping out of the sides of his puffy lips and slowly rollinging down his jaw, down his neck.
Kirishima was hard again in seconds. “Fuck- do you ever get tired?” Bakugou hisses and Kirishima laughs and pulls him up by his elbows.
“Ready for round two?” He asks but doesn’t wait for an answer as he also stands and spins around to bends Bakugou over onto the mattress. His ass was in the air, legs spread wide, puffy pink asshole on display, lube and saliva shinning around the hole, and his face was shoved into the mattress by one of Kirishima’s large palms.
“Again with this?” Bakugou groans as Kirishima forcefully rolls his face and chest into the cum that was on him from before.
“Now it’s time to full your ass up!” Kirishima laughs and spanks one of his cheeks.
Bakugou jumps with a sour face but says nothing as Kirishima slowly pushes his way inside.
This time he pumps Katsuki’s dick in time with his thrusts, it almost feels like too much.
“Hah, hah, eiji-.” Bakugou whimpers into the sheets as Kirishima grins down at him and fucks the abused hole.
“If you pass out on me I won’t stop fucking you until I’m satisfied.”
Bakugou shivers at the image of Kirishima fucking his unconscious body but quickly pushes the intriguing thought away to grunt out, “Who the fuck said anything about p-passing out.”
Kirishima grips his hips and forces Bakugou to meet his unforgiving thrusts, they both let out long moans. He angles the hips higher so Bakugou is forced to arch his back and Kirishima sticks his cock in as far as it can reach before pulling out and snapping back in again.
With his face firmly held down on the mattress Bakugou can look down and see the buldge in his stomach from Kirishima’s dick. Tentatively he puts a shaky hand over it and shivers at the feeling, knowing that his lover had such a large dick was a turn on. That’s the last thing he can think about before exhaustion hits him and he passes out.
-
When Bakugou wakes up he registers that he feels sticky and..full? There are arms around him and when Bakugou opens his eyes he sees the walls moving closer and then further, and closer, then further, front then back, then front then-? What?
It’s then that Bakugou realizes that the walls aren’t moving. He is. He looks down and sees his limp fat red cock bobbing in time with the thrusts and lets out a howl of agony when he realizes how swollen his asshole really is.
“KIRISHIMA!” He yells angrily but that doesn’t stop Kirishima from rhythmically plugging up his hole.
“I told you I wouldn’t stop until I was satisfied right?” he asks, reach up to twist a nipple and leave a smooch on his cheeck. Bakugou feels dizzy.
“H-how long have you b-been at this for?” he manages to stutter out.
In lieu of a response Kirishima pushes down on Bakugou’s stomach and he chokes when he feels cum rushing out of him. Sloshing down from around Kirishima’s dick that is still fucking into him, leaving a messy pile of cum that they’re both laying on.
“I’m almost- there, hah, ah, ah,” And with a snap of his hips Kirishima grips Bakugou’s hips, forcing him flush against the other’s groin as he cums again, shooting into bakugou who shivers at the feeling.
“You sick fuck let me r-rest.”
Kirishima pulls out with a sickening squelching sound and without the hole being plugged up by his cock, cum come rushing out and Bakugou’s dick twitches limply at the feeling of warm semen spilling out of him and onto the mattress.
“You look really good like this, Katsuki.”
Bakugou sneers at him. “Fuck off, shitty hair.”
Red eyes meet red as Kirishima chuckles and affectionately brushes the blond hair away from his forehead “Go shower, I’ll make you lunch.”
Bakugou cringes when he sits up and a dull ache from his ass shoots up his spine.
“……I think you’re going to have to carry me into the shower.”
Bakugou silences Kirishima’s howls of laughter with a swift pillow to the face.
