Concept 13 - Hidden Talent

Inspired by some wonderful Kirichako art and my mind is racing.
CW: bottom?Kiri, auto penetration, voyeurism, stay with me on this one, let's say they're in their third year or something

Bakugou can't even remember what brought the conversation about, but he doesn't care. That random conversation brought him here, and it's incredible.

—————

"Hidden talent?" he repeats.
"Yeah. Someone asked me what mine was recently and I couldn't tell them because...well, I kinda only want you to know about it," Kirishima explains. "But I thought I'd ask you yours too, to, I dunno, level the playing field, I guess?"
"Tch," the blonde scoffs, signature cocky grin splitting his face. "The fuck do I have to hide? I'm good at everything!"
"Babe, you don't let anyone into your room because you don't want anyone to see your All Might merch and romance novels-" Bakugou shoves his hand in his face to cut him off.
"Alright! Alright! Shut the fuck up!" he gripes with a growl. He sighs, thinking a bit, before tossing his head back in embarrassment. "When we were kids...ugh. Fuckin' Deku and I memorized all the theme songs and intros to the All Might cartoons...and I still remember all of them."
"Aww, babe! That's cute! Heh, mine is in a way different playing field, 's kinda embarrassing," Kirishima admits.
"Well too bad, Shitty Hair! You gotta make us even!" Bakugou insists. There's no way he's spilling that embarrassing shit for nothing. Kirishima squirms in place as a blush starts to cover his cheeks.
"Alright...but don't laugh at me, alright?" he finally says, scooting closer. Bakugou raises an eyebrow at him.
"I make no promises." Kirishima pouts at him, but reluctantly scoots closer, whispering something that makes the blonde's eyes blow wide. He can't bring himself to say it above a whisper. Bakugou stares him down inquisitively when he pulls back, a blush coming to his cheeks as well.
"No you fuckin' can't." Kirishima nods.
"I...I can." There's a long pause.
"Show me."

That one conversation led him here— sitting on one end of his bed, while his boyfriend sits at the other with his back against the headboard. His pants and underwear had been discarded somewhere, leaving only his tank top, the hem between his teeth so he could see where his hand was busy between his own spread legs. Carefully, meticulously, he fingered himself open. His eyes flicked between his swelling cock and the fiery eyes of his boyfriend. He was practically melting under his gaze, which was locked on where his index and middle finger stretched him open. He never expected Katsuki to be a voyeur, but the tent in the blonde's sweatpants proved him otherwise. There was something intimate about it. Maybe it was the fact that Katsuki was the only person who got the pleasure of watching this lewd display. Whatever it was, it was a perfect excuse for the amount of precum that was dribbling onto his stomach. He forced his gaze back down to his prep once he felt he was ready, extracting his fingers and shifting a bit. He needs two hands for this. It's a shame he looked away, since he missed how the blonde bit his lip as his cock twitched at the sight of his lube-slicked hole fluttering around nothing. He worked slowly so Bakugou could see exactly how his little "hidden talent" worked.

With one hand, Kirishima gingerly cupped his balls— heavy and swollen with the sheer amount of cum he's capable of making thanks to his hyperspermia— and pulled them aside, holding them there while his free hand lined his impressive ten inches up with his taint, gently pressing down until the tip covered his entrance. Slowly, he pressed the blushing, leaking tip against his hole until it slipped past his rim. The hem of his tank top fell from his teeth as he let out a soft moan at the feeling of his own girth.
"Holy shit..." He heard Bakugou whisper to himself. He held his aching cock in place as he looked up, blush darkening at the look on his boyfriend's face, as well as the size of the wet spot on the crotch of his sweat pants. If he didn't know better, he'd think he was drooling. He chuckles a bit, snapping his boyfriend out of his trance.
"See? Told you I could do it," he teases.
"Yeah, you did," Bakugou says, nodding brainlessly, absolutely mesmerized by the display. "Shit, Ei, you look so good. Have you ever cum like that?" he asks, shifting and shamelessly palming at his own erection from outside his sweats. The redhead is almost at a loss for words, suddenly shy again.
"Y-yeah, once or twice, to see what it'd feel like to um...to have cum inside..." he admits, ever so slightly pressing his cock deeper.
"Fuck, that's hot," the blonde sighs. "Can you show me?"

Kirishima's brain needed to catch up with the blood making his dick pulse with need. It's a little embarrassing, but he can't help himself from nodding, gingerly pressing down on his own throbbing cock, pressing it deeper into his heat. He starts a slow pace, allowing himself to fall into the pleasure, looking down at himself with lust hazed eyes. He almost forgets that Katsuki is there as the press of his hand speeds up, desperately fucking himself with his own cock. He pays no mind to the drool threatening to spill down his chin, instead focused on the throbbing of what feels like his entire crotch. His free hand finds desperate purchase in the comforter, heels digging into the mattress. A second sound of panting breath catches his attention, making him peek up to see his boyfriend staring hungrily at his groin, sweat beading at his forehead. His eyes sweep down to see that at some point, he had pulled his sweatpants down enough to free his own erection, which he was fisting furiously, presumably only using spit and a copious amount of precum as lube, while his other hand held a white knuckled grip on a patch of his sweatpants.
"Mm- hah!~ L-like what you see?" Kirishima teases through heaving breath and moan.
"Ngh, God, yeah," Bakugou groans with need. "You look so fuckin' good, Ei.~ Wanna see you cum on your own cock.~" As if on cue, the redhead's cock jumps at those words, eager to follow suit.

Kirishima bites his lip, barely containing a moan at the desire in Katsuki's voice, so deep and thick and God, he wishes he were closer, growling filth in his ear while helping him get off, but his heated gaze alone is enough to make the spring in his stomach coil tight, tight, tight-
"Ah!~ K-Katsuki!~" he moans, a quick, furious pace driving his cock into himself as he comes undone under those fiery eyes, cum spilling into his own sensitive hole in copious amounts. He barely notices the dip in the bed as Bakugou hurriedly crawls forward and finishes himself off on Kirishima's abs, holding the headboard in a death grip next to sweat dampened red hair. When their blood catches up with their brains, and Kirishima's slowly softening cock slips out of his hole, bringing a string of sticky cum with it as it does, they finally lock eyes. Kirishima can't help the dorky grin that dons his face. "So...didja like the show?" Bakugou's response comes in the form of a deep, messy, and frantic kiss, his lips wet with drool and tongue eager to lick into serrated jaws, guided by hands on his cheeks. Kirishima is surprised, but eager to reciprocate, nipping at a plump bottom lip just how he likes it. After a minute, he pulls back to yank their shirts off and shuffling awkwardly to get his sweats off.
"Just you wait 'til I'm hard again, you sexy bastard," he growls, discarding his sweatpants off the side of the bed, making the redhead chuckle.
"Yeah?" Kirishima teases before he's pulled back to his lips. "What're you gonna do?" They speak between eager, sloppy kisses.
"'M gonna fuck...the ever living...shit outta you.~"

And he did. Lol hate to cut it off there but I can't think of how else to end it. Hope y'all enjoyed it.
