Work Text:
Katsuki will be the first to admit it: he’s got a nice rack. They’re huge, easily filling up his hands, soft and supple to hold. And oh god, are they sensitive. Just a few minutes of having his nipples sucked and toyed with is enough to have him writhing on the bed. Honestly, he feels like he could get them to lactate if he tried hard enough, and wouldn’t that be a sight? A set of good ole mommy milkers on the Number 2 Pro Hero.
So, yeah, he’s got great breasts… for a cis guy anyway.
Izuku certainly agreed, if the way he seems to obsess over them is any indication. The primary source of his confidence came from his horny, equal parts Kacchan and boob obsessed boyfriend. Hell, the first time he got his hands on them it was all he could focus on.
“Wow, Kacchan,” Izuku had marveled, squeezing and pushing them up together to create cleavage, “your tits are amazing!”
At the time, they had just graduated UA, literally just walked across the podium a few hours before. They were finally alone in their new apartment and perhaps a tad drunk when they started casually talking about their body count (yes, their sexual body count, get your mind in the gutter for this one) and then it not so subtly shifted into a conversation about what they like in bed. At some point, one of them either grew a pair or got tipsy enough to start taking the other’s clothes off. Hence why Katsuki was half nude and being fondled.
“Tch, only you would say that.” Katsuki huffed, willing the blush to stop spreading across the face and the hot arousal to cease seeping into his groin. “Pervert.”
“Yeah, m’a pervert for Kacchan.” Izuku breathed, wrapping his lips around a perky bud.
Katsuki gasped, not expecting it to feel that good. He buried his hands in Izuku’s hair, unsure if he wanted to wrench him away or push him closer. Izuku quickly picked up on his hesitations and backed off a bit. That was when Katsuki made up his mind about it.
“Hah?” He sneered, shoving Izuku closer. “You talk big shit about how much you love my chest and now you want to pussy out?”
Izuku’s eyelids fluttered as he resumed with gusto.
After several months of constant praise and body worshipping from Izuku, Kacchan slowly started to appreciate his tits. It started with reluctantly accepting that, okay, they did feel pretty great when they were played with. Plus, he could drive Izuku up the wall with them, which was always a bonus. Sometimes, just to be an asshole, he would use that knowledge for Evil. His favorite way was to slip into the bathroom during a long work meeting to take some quick pics and then sneakily return to his seat. Then, watch Izuku’s face as he opens the text to see a photo of Katsuki’s pecs spilling from his partially undone button up. His eyes would practically bug out of his head, freckled face flushing until he resembled a strawberry. Then he’d quickly make a mad dash for the exit. There isn’t a word in any language that could properly encapsulate the rush of power that gave him.
Somehow though, it took him two whole years to come up with literally the most incredible tit related thing ever. And you know what the worst part was? Wasn’t even his fucking idea!
It all started when someone threw a bra at him when he was on patrol. The only warning he received was someone yelling “PLEASE LET ME FUCK YOUR TITS DYNAMIGHT!” and then bam! Bra in the face. Thankfully, it was clean, but startling nonetheless.
By the time lunch rolled around, the clip was everywhere online. #BigBazoingasBakugou was trending on just about every social media as the Dynamight titty stans rejoiced. Honestly, it wasn’t the weirdest fan interaction he’d ever had, but that didn’t make it any easier to hear his friends laugh themselves to damn near incontinence in the break room.
“How-tit-zer Impact!” Kirishima howled with laughter, leaning heavily on Kaminari, who was pounding the table in mirth. Next to him, Mina squirted chocolate milk out her nose.
“Hahaha, very funny.” Katsuki gritted his teeth, doing his best not to explode anything. He kept his arms crossed, hands pushed between his arm and chest tightly. Thank god his costume was fireproof, because otherwise he’d probably be nude right now. Whether it would be from his Quirk or embarrassment was anyone’s bet.
“Don’t let them get you down.” Sero snickered as he threw an arm around Katsuki. “They’re just jealous of you.”
Katsuki scowled, shrugging Sero’s arm off.
“Nah, we ain’t jealous of Kat,” Kaminari clarified, wiping his eyes, “if anything, we’re jealous of Midobro. He’s the one who gets an all-access pass!”
And with that, Kaminari reached out and gave one of Katsuki’s pecs a squeeze for good measure. Katsuki spluttered, too flustered to react. By the time he finally got his wits about him, Kaminari was already out of arm’s length and cackling his whole head off. He and Kirishima kept dogging him all day, asking him if they could fuck his tits. It was only when Katsuki was about to explode (literally) that an idea came to him.
There was really only one thing to do.
He whipped out his phone as typed out a text.
Bakugou Katsuki >>> Midoriya Izuku
Kacchan: You better be pumped when I get home, nerd.
-
The text from Kacchan was sudden, but far from out of character. Far, far from it. There were plenty of times Izuku would be home by himself or preparing to head home and receive a text of a sexual nature. Usually it would be a warning or a command of what to be wearing or doing. Other times it would just be a lewd image or a simple I’m going to hog tie you and use you for hours without letting you cum until you lose your voice from begging so much.
You know, nothing too out of the ordinary.
So, Izuku obediently got out his pussy pump and got to work.
As he steadily pumped himself, he tried to imagine what Kacchan wanted to do tonight. Did he want Izuku to fuck his mouth? Maybe fuck his thighs, or even his ass. Well, as best as a pre op trans guy could do that. Fortunately, medical advancements and genetics had blessed Izuku with a rather large t-dick. A good 4 inches, if you rounded up, but it’s not about the equipment, it’s about the equipment… and by that Izuku meant sex toys. They had plenty of extenders for trans guys that both he and Kacchan loved.
He squirmed in place at the suction, picturing Kacchan spread out, ass in the air. Ever since they had started dating, pornography was totally ruined for him. Nothing would ever be as good as the real thing. Thank god their relationship had given him plenty of material to work with for the rest of his fucking life.
Just as Izuku was starting to reach his limit, panting and whining, their front door was unlocked and kicked open.
Izuku yelped in surprise, accidentally squeezing the pump. He choked out a moan as his body seized up and nearly came. By the time he finally got a hold of himself, Kacchan was looming over him, caging in his body with his hands on either side as he climbed up his body, stopping only to gently remove the pump from his swollen cunt.
“H-hey Kacchan,” Izuku greeted, trying not to focus on the wetness seeping from his pussy, “how was work?”
“Annoying,” he grunted, sitting back to straddle Izuku’s waist as he began stripping off his costume, “fuck, have you checked social media at all today?”
“No?” Izuku cocked his head. “I never check the internet on my days off, you know that.”
“Good.” Kacchan huffed, tossing his shirt over his shoulder. Before Izuku could ask anymore questions, he found himself captured in a scorching kiss.
Kacchan kissed like he fought, all out, no holding back, yet paying careful attention to his target. He’d long ago memorized what made Izuku’s chest hitch in pleasure and always seemed to hit it out of the park. Today, his technique was sloppy, but not in a bad way. It was messy, sticky, slick and wet.
And then suddenly Izuku’s whole world shifted. He made some kind of squeak as his body was flipped and man handled. It wasn’t until the dizziness lifted that he finally registered what had happened. Kacchan had flipped them so Izuku was the one on top, which was a first. Usually it was the other way around.
Not the part about Kacchan being on the bottom. That was a fairly common occurrence.
Before Izuku could parce up enough brain cells to ask what was going on, Kacchan answered the question for him.
“Izuku,” his voice was low and rumbly, sending shivers up and down Izuku’s spine, “you’re gonna fuck my tits.”
Heat flashed through Izuku’s body at those words. He choked out a moan, rutting against Kacchan’s stomach. It wasn’t a question or command, it was a fact.
“You want that?” Izuku asked, wrapping around his own throbbing length, stroking it desperately. “I would love to, Kacchan.”
Kacchan smirked, cupping his pecs and squeezing them together.
“The fuck you waiting for then?” He sneered. “Get to work, perv.”
“Only for Kacchan.” Izuku breathed as he got into position, pressing his cock between the cleavage. “Kacchan’s pervert.”
“Better be.” Kacchan grinned, taking the buds of his nipples between his fingers to play with. “You’re all mine.”
Izuku moaned at the possessiveness as he started to thrust in and out of Kacchan’s perfect tits. The slick from his cunt spread over smooth skin, making the glide that much better. The wet shlick shlick sounds filled the room, accentuated by their grunts and heavy breathing. At some point, Izuku looked down, his eyes catching on the burst shaped scar on his lover’s chest. Out of instinct, he pressed his hand over the mark, feeling emotion well up in his chest as he remembered the moment these badges of valor were earned, when Kacchan sacrificed himself for Izuku.
And now here he was, fucking his tits.
That realization was what pushed over Izuku over the edge- not the part about titty fucking, but just how long their journey had been up to this moment.
“Katsuki!” Izuku crooned as he squirted, flooding Kacchan’s chest. Kacchan groaned, eyelids fluttering as he watched Izuku shamelessly grind against him.
“You’re so fucking gorgeous,” he husked out as Izuku finally came down from his high. “I wanna watch you cum all day.”
Izuku chuckled, swiping a hand through his sweaty hair. “Then make me, coward.”
Kacchan’s eyes flashed dangerously, and Izuku knew he was in for it now.
