The idea of sex isn’t new to Katsuki. He’s a hormonal teen. He’s had his fair share of wet dreams and, frankly embarrassing, fantasies. He’s not ignorant… Just… Never had the desire to act on it.
Time being a horny teenage boy could be better spent training to be the best hero.
Of course, that all shifted with the introduction of his boyfriend. But it could also just be the Deku effect, and how he always seemed to change his life for the better. If ‘for the better’ meant acquiring a kickstart to his libido.
But even before getting together, Deku did things to his arousal he’d never want to admit out loud. Katsuki just happened to oogle Deku on the bench press one day, taking in the definition of his toned muscles he hadn’t cared to notice before. Wow… Deku could probably bench press him . Manhandle Katsuki into whatever position he could handle, bend him in half and take him however he wanted. And here he was, for the first time, dripping wet .
Despite Katsuki toeing into sexual expeditions – which tended to be roughly shoving his sticky, sweaty fingers into his barely slicked cunt with the inexperience of a bumbling, baby kitten learning to walk – it was only so gracious that his body was unreasonably sensitive that he was able to pull a strenuous orgasm from his pussy.
Lying sprawled out on his bed, drenched in sweat from his activities and brain hazy in his post-orgasm daze, he wondered if being horny was too much work to deal with. But then he hardened his expression because nothing is ever too much work for Bakugou Katsuki.
Honestly, Izuku was a bit of a freak. He could never admit it to Kacchan, but the things he imagined doing to his partner were downright sinful.
He, like Kacchan, had never really had the time to spend on frivolous ordeals with others. They’ve always gravitated towards one another, perhaps drifting apart but never out of orbit.
But that doesn’t mean he doesn’t do his research. Kacchan already graced Izuku with his heart — something Izuku could never have dreamed of a few years ago — and he was willing to do everything to be the best partner he could (Kacchan was in 1st place because Kacchan was the best at everything ).
And then Kacchan declared one day that they were going to fuck and Izuku better get ready for it.
So like the freak he was, Izuku scoured the interwebs. He knew vaginal orgasms were notoriously difficult from penetration, alone. He’d have to study the anatomy, okay? Innately, he knew Kacchan would want to take the reins in their relationship and in the bedroom, but Izuku would be damned if he couldn’t please his partner, his Kacchan .
However, faced with the real deal, Izuku wasn’t sure he’d be able to measure up.
Katsuki lay languidly across the bedspread, naked as the day he was born. He pouted with a bored expression, gaze purposefully pointed away, but Izuku could tell he was nervous, too.
Izuku thought he was stunning. He sucked in a breath that did little to calm his own nerves. His hands were clammy and he was jittery with unkempt energy.
He was going to chalk it up to performance anxiety, and not the overwhelming sense of dread about… their first time . Ludicrous.
“Don't chicken out now, nerd,” Katsuki’s grumble shocked Izuku back into focus. Compared to his usually pale complexion, pink was blossoming from his cheeks to his shoulders, maybe even further spreading downwards slowly.
Wow .
Katsuki was so wet.
His chubby little pussy lips glistened with barely contained slick. They glowed against his plush, beautifully toned thighs and his cute, pert little clit took a peek between the labia minora, shiny with wetness and arousal.
‘Kacchan is beautiful.’
“Shut up,” Katsuki hissed as he hid his flushed cheeks into the pillow, albeit while spreading his legs and showing off his gorgeous insides . “You’re so embarrassing. Hurry the fuck up.”
Izuku swallowed. Fuck . “Yes, Kacchan.”
Palming his erection, Izuku pressed onto the bed, crowding his partner’s space. He leaned over Katsuki and boxed him in with his arms, prompting them to only blush redder at their sudden closeness. Dropping down to nose at the other’s neck, Izuku breathed in Katsuki’s sweet scent. The aroma of candy caramel and just Kacchan Kacchan Kacchan kicked Izuku into motion.
Katsuki was rendered breathless as the green haired boy kissed the front of his spasming throat and sucked at his pulse point beating erratically.
He was usually sensitive but Izuku really turned it up to the 11s. The blond wiggled, squirming, rubbing his wet thighs together as he panted helplessly under Izuku’s mercy.
When the other drew back, Katsuki turned to glare dazedly at him. Why the hell did he stop?
Squirming pointedly, Katsuki tilted his hips up, slinging his legs around Izuku’s waist and locking them together.
Izuku briefly swore under his breath as Katsuki began to grind at his erection, slathering the hard cock in his juices.
Labored breathing echoed through the room as the two gave into their instincts, grinding up against each other without restraint.
“Hngmm…” Katsuki whined in pleasure as the tip of Izuku’s cock jabbed softly at his throbbing clit.
“Does that feel good, Kacchan?” Izuku breathed out, hands now wandering all over Katsuki, rubbing along his sides, gripping at the small of his back, thumbing at his sensitive nipples, groping his dainty waist. He couldn’t get enough.
“Y-yeah…” Katsuki panted out in return.
The sensations were electrifying, shots of euphoric sparks racing through his veins. Katsuki never thought he could feel this good. But as always, Izuku had to prove him wrong in the best way possible.
“Aanhh!” Katsuki suddenly arched his back as the buildup of pressure in his core snapped, flooding his body with warmth and melting his brain in a fuzzy haze.
Katsuki could only struggle for air as his entire body spasmed in ecstasy. The fluttering of his pussy pulsed against Izuku’s cock, smattering it in more slick.
“Shh, Kacchan, shh…” Izuku cooed, finally reaching down to feel at Katsuki’s sopping pussy, clueless to the orgasm that had just run its course. Katsuki cried out in overstimulation as Izuku thumbed at his pulsing clit, frantically rubbing at the heat.
“D-De-ku— hngg! I-I’m—“ Katsuki fought to breathe, all his senses solely overwhelmed in the pleasure.
“I know, Kacchan. I’m trying, I’m trying. I’ll make you cum, promise. Just bear with me. I’ve never done anything like this before.” Izuku pinched and pulled and rubbed Katsuki’s swollen clit with vigor, only serving to jumpstart another orgasm crashing down into Katsuki like a tidal wave.
Screaming silently, Katsuki rocked his hips more – to chase the pleasure or dissuade Izuku? He didn’t know. Back arching beautifully, the blond could feel his body fighting with itself, because holy shit, Katsuki didn’t think anything could feel this amazing.
“Kacchan? Oh, I’m sorry. Please don’t cry!”
Katsuki blinked teary eyes open. He didn’t even realize he started crying. Wow . Izuku had him fucked up. He whined pathetically, grinding up into Izuku again to urge him to keep going.
Izuku’s breath stuttered, taking in the gorgeous sight. His dick pulsed in desire. Kacchan was asking for more . Izuku needed to ramp up his game.
Izuku let himself collapse his entire weight onto Katsuki, drawing out a squeak, before silencing it in a passionate kiss.
Katsuki melted. His senses blended together into mush. Foggy warmth from multiple orgasms and this mind-melting kiss only conjured up whiny moans that his partner swallowed up.
Izuku lodged his tongue deep into Katsuki’s throat, feeling, tasting. The wet muscle pushed and probed, filling his cavern, shoving at the other and fighting for dominance. Katsuki gasped for air as Izuku pulled away, only to have his breath instantly taken away in another invigorating kiss.
Scarred hands fumbling, Izuku drew back to guide his stiff cock, plunging into Katsuki’s socking heat. Absolute bliss. Katsuki’s pussy pulsed and fluttered angrily, clearly trying to milk Izuku for all he’s worth.
“AAaahnnhh!!” Katsuki arched his back beyond what Izuku thought was humanely possible. His mouth gaped wide open, cheeks wet with saliva and tears. He was shaking again. Izuku would have been more concerned if he hadn’t been trying to keep himself from bursting on the spot.
A moment later, Katsuki slumped like a doll cut off its strings. Izuku nuzzled the blond’s neck, whispering comfort and nipping at the sensitive skin. It only drew more whines, urging Izuku to start rocking his hips.
“Hah…hahh… ‘s t’mush too- m-m-uch… De-ku…” Katsuki slurred between panting breaths. He thought this was their first time. How had Izuku already – and easily, considering he wasn’t even aware Katsuki had already cum – pulled three orgasms from him when Katsuki had struggled with just one by himself?! What the fuck .
It was Izuku’s turn to whine, brows pinched in concentration because he did not want to cum yet . He had to please make Kacchan feel the best he possibly could. He rubbed comfortingly on Katsuki’s scalp and the small of his back before he surged upwards and flipped Katsuki over.
“MMph!” Katsuki faceplanted into the fluid-soaked pillow with a thump. The feeling of being twisted on the other’s length scraped at all his insides in a way Katsuki could never have imagined. It triggered another mindblowing orgasm, his back arching and hips unintentionally bucking up onto the dick. He felt Izuku pushing on his love handles, forcing his body to lie prone on the dirtied bedsheets.
“I can’t hold back anymore, Kacchan… I’m sorry.” Izuku mumbled into his ears, sending shivers up his spine despite the pleasured tremors circling through his body.
Katsuki shook where he lay, fingers clenched tightly on the sheets as a way to ground himself. He rubbed his thighs together as Izuku’s entire weight and stature caged him. Katsuki couldn’t even spread his legs, absolutely soaked thighs trapped between Izuku’s knees, but it only served to tighten his pussy around the other’s dick.
Just when he thought that had been enough, Izuku slowly drew his hips back, inching his cock out at a snail’s pace. Then he snapped back down, deeper than ever into Katsuki’s core.
“NNGHHMMNN!”
Katsuki convulsed at the burning heat and euphoria, eyes crossed in pleasure as he bit into the pillow. Fuuuuck . Everything was warm and wet and just fucking amazing . Watery slick shot from Katsuki as his pussy began to clench repeatedly in a powerful orgasm.
Katsuki barely even registered the fact he was squirting, before Izuku began to pull out again.
“W-wait– De– MHMM!” Katsuki panicked, but Izuku only shoved at his shoulders, forcing his head and chest to press into the bed.
Izuku snapped back in, slowly pulled out, and slammed deeper, pounding harder, and jackhammering faster, over and over.
His insides weren’t given a single moment of rest. G-spot repeatedly hammered into only making him squirt endlessly. His walls were numb but still alight with pleasurable sensations. Izuku even probed his way at his cervix .
It was driving Katsuki insane. He couldn’t stop cumming and squirting and Shitty Deku didn’t even realize . He could only lay there, spasming, convulsing, trembling with overstimulating orgasm after orgasm.
Katsuki didn’t even realize he passed out.
“Was that good? Did you cum, Kacchan? I didn’t realize you fell asleep. It must have been really boring. I’m terrible at this, oh god. I’m sorry for being a terrible boyfriend. I even did research and
everything
. I’ll make it up to you next time, Kacchan. Please forgive me.” Izuku began crying after his spiel, looking like a dejected puppy.
Fuck you fuck you fuck you
.
Katsuki groaned. “Are you kidding me? You just fucked me within an inch of my life and you’re asking if that was
just
good?”
Izuku blinked. “Huh?”
“Did you even consider researching what an orgasm would look or feel like?”
“Oh…”
“Yeah, Shitty Nerd.” But Katsuki leaned forward, laying a slow, grateful kiss on Izuku’s forehead. “You were amazing…” He grumbled, “Let’s do this again sometime, yeah?”
Izuku just nodded eagerly.
