Work Text:
The day Denki’s fate is sealed as the horniest freak he’s ever known starts like any other. The sun is dragging itself into the sky by the time he trips half-asleep through the front door of his apartment.
“Morning, sunshine!” Eijirou chirps from the kitchen. It’s barely audible over the whirring of the blender as he throws together what he calls breakfast. Denki stopped asking about the ingredients after he once saw a boiled chicken breast go into the mix. “How was work?”
“Ughhnnn,” Denki says eloquently. He haphazardly steps into his house slippers, trudges over to the kitchen, and lets his forehead fall against Eijirou’s broad back.
Eijirou hums understandingly. “At least the pay is good, right?”
The noise Denki lets out is somewhere between a whine and a grumble.
“I know, I know.” The grinding sound of the blender winds down—and maybe Denki should ask him about the ingredients, actually, because that noise is concerning. Eijirou turns and pats the top of Denki’s head. Denki gratefully buries his face in the deep valley of Eijirou’s pecs. “By the way, did you check your messages at all before you got home?”
“Forgot to charge it,” Denki mumbles. “Died on my shift.”
“You gotta stop doing that, man.” He can hear the frown in Eijirou’s voice. “It’s not safe.”
Denki tries to mumble something like I hope you know I appreciate how much you care about me, even if I can’t string a sentence together right now. Instead, he says, “Hngh.” Still, he’s confident he’s gotten his message across, if the way Eijirou is stroking his hair is any indication. “Why’d you ask?”
“Ah. Well.” Eijirou clears his throat. “So, I was thinking about the whole roommate situation.”
Denki perks up. “You found someone to take Mina’s room?”
“I…think so.”
“Thank you, sweet baby Jesus,” Denki moans. “I can stop taking so many extra shifts now.”
“Right, yeah. Um.” There’s a level of uncertainty to Eijirou’s voice that should probably concern Denki. It’s hard to be worried, though, when he’s loopy from sleep deprivation and preoccupied with the good news of someone else to split the rent with. “You might need to spend a little more time at home, actually.”
“Shit, man, you don’t need to tell me twice,” Denki says dreamily. He’s going to take so many naps. In his bed, in Eijirou’s bed, on the couch, maybe on the kitchen counter if he’s feeling adventurous—
“No, I mean, you might be like…legally obligated to stay home.”
The words slowly trickle into Denki’s awareness like they’re dripping through a coffee filter. After a few long moments, he pulls back slowly and narrows his eyes at Eijirou. “Legally obligated? What kind of roommate situation did you sign us up for?”
“Well, when I said roommate, that might not have been the most accurate word in the world,” Eijirou admits. “I mean, it is gonna be a guy who lives in our apartment! And it’s gonna cover at least a third of the rent, if not more.”
“But?”
“But…it might be more like rehabilitation, maybe.”
“Rehabilitation?” Denki yelps. “I’m not a doctor! What if I accidentally kill them? Ei, I’m too young and pretty to go to jail—”
“Not that kind of rehab!” Eijirou says hastily. “He’s a hybrid.”
“Oh.” Denki blinks. “Well, shit, man, why didn’t you just say so?”
Eijirou’s shoulders drop in relief. “You’re not mad?”
“Nah, dude.” Denki shrugs. “I mean, it’s just a person with some kinda wild traits, right? How bad could it be?”
In hindsight, Denki should have known saying that aloud was asking for trouble.
So, maybe some kinda wild traits doesn’t quite cover it.
Their new roommate is preceded by copious amounts of paperwork that makes Denki’s head spin. He’s always heard about unlucky hybrids raised in shady [mills?] and treated like inhuman products to be sold for entertainment or labor. They don’t make up the majority of the hybrids he sees out in the world, though. All the hybrids he’s gone to school with or worked alongside either grew up with their own families or were rescued and rehabilitated at a young age. Sure, they had some characteristics that weren’t entirely human—Denki clearly remembers a cat hybrid classmate who’d been fond of rubbing her face against her girlfriend’s—but they were still people. As far as Denki was concerned, they weren’t different from him in any way that mattered.
Of course, Katsuki challenges that assumption.
He arrives bright and early on a Monday morning, accompanied by a volunteer from the rescue agency. Within ten seconds of the volunteer leaving and shutting the door behind them, Katsuki is wriggling out of his clothes. A plain black T-shirt and loose sweatpants hit the floor before Katsuki follows suit.
Denki looks over to Eijirou, but his roommate seems just as surprised as he is. They watch, frozen in silence, as Katsuki squirms on the floor in nothing but boxers, growling at his socks as he tries to tug them off.
Finally, Eijirou snaps out of the spell and rushes forward. He stops short before he can actually touch Katsuki and hovers awkwardly with his hands outstretched. “Hey, dude,” he says cautiously. “Is there something wrong with your clothes?”
“Feels bad,” Katsuki grunts as he manages to work one sock free and tosses it over his shoulder. “Human clothes are stupid.” Finally free, Katsuki leaps to his feet—or maybe his paws? His lower half is furry with digitigrade legs—and reaches for the waistband of his boxers.
“Whoa, there!” Denki yelps, leaping forward to grab Katsuki’s arms and stop him from stripping down to buck-ass naked in their living room.
“Fuck off.” This time, Katsuki’s voice is somewhere between a growl and a whine.
“You gotta wear clothes, though,” Denki pleads. “Otherwise, it’s—it’s not decent.”
Katsuki stops struggling for a moment to glare at Denki. “Decent? Look at this shithole. And you wanna talk to me about decent?”
Denki gawks. “Shithole?”
“Yeah.” Katsuki gestures to the living room with a wrinkled nose. “All of that.”
“It’s not a shithole!” Denki replies immediately.
“Yeah!” Eijirou agrees. “And even if it usually is—”
“Which it’s not.”
“Which it’s not!” Eijirou continues, “But we cleaned especially for you, man. Vacuumed and everything.”
“Vacuumed,” Katsuki scoffs, distaste clear in his voice. “You can use that bullshit as much as you like, I can still smell every nasty thing you’ve done on that couch.”
“What kind of—” Denki starts before his brain catches up. Immediately, his mouth snaps shut and his cheeks start to burn. He hadn’t planned on talking to their new roommate about their whole unnamed-occasional-fooling-around situation, mostly because he and Eijirou haven’t talked about it themselves. Can’t a guy live with his best friend and sometimes suck his dick in peace?
Apparently not, when dog hybrid noses are involved.
Denki catches Eijirou’s eye for a moment before they both look away, flushes painting their cheeks.
“I’ll take his stuff to the bedroom,” Eijirou mutters as he makes a hasty retreat.
Heaving a sigh, Denki looks at the (now victoriously nude) hybrid on his sitting room floor. Maybe this is going to be more complicated than he thought.
Katsuki’s personal vendetta against clothing is just the tip of the iceberg. Every day they live together brings a new revelation.
Some are harmless, if a little weird. Despite his regular complaints about being able to “smell all their bad decisions,” Katsuki has an undeniable fascination with their dirty laundry. The first time Denki steps out of the shower to the sight of his new roommate rooting through his discarded work clothes nose-first, he almost has a heart attack. Eijirou knows not to come into the bathroom when it’s in use, but Katsuki apparently never got the memo.
Still, as strange as it is to watch Katsuki snuffling at his briefs, Denki can’t bring himself to interfere. He has some pretty out-there habits himself. As long as no one’s chewing him out for missing laundry day again, he figures there are plenty worse habits Katsuki could pick up.
Some of Katsuki’s habits could be dog-like, but they could also just be…well, Katsuki. Over the years with Eijirou and Mina, Denki’s grown sticky fingers when it comes to his friends’ food. Eijirou is more chill about it than anyone, human or hybrid, that Denki has ever met.
As for Katsuki, when Denki reaches for a slice of bacon off his plate one morning—well, Denki doesn’t think Katsuki would actually bite him, but he doesn’t feel like finding out. Then again, Eijirou is exceptionally easygoing, anyway. It’s not too much of a surprise that Katsuki is more territorial about his food (although, the flattened ears and bared teeth give Denki more of a scare than he’d like to admit).
Probably the worst adjustment to make is to Katsuki’s embarrassing habits. Well, habit. Ever since Katsuki called out their less-than-entirely-platonic extracurriculars on that first day, Denki has accepted that part of being around Katsuki is regularly getting roasted. He can live with that—hell, he can even learn to think of it as a sign of affection. Probably. Eventually.
Now that Denki knows Katsuki has a barbed tongue better suited for a feline, he doesn’t get embarrassed by his snarky comments. No, he only gets embarrassed now by the sight of Katsuki—prickly, wary, arrogant Katsuki—humping whatever he pleases, whenever he pleases.
It’s a dog thing, Denki tries to remind himself a little hysterically whenever it happens. It does little to erase the image of Katsuki single-mindedly trying to fuck the very couch he’d turned his nose up at when he first arrived. Then again, it seems like it’s only an issue for Denki and Eijirou. As far as Katsuki’s concerned, he’s just practicing his god-given right to rub his balls on everything.
At the end of the day, Katsuki isn’t the worst roommate Denki’s had. Even with the underwear-sniffing and the couch-fucking, Katsuki is painstakingly neat. Surprisingly introverted, too, considering he prefers to walk around in the buff. Sure, there’s an adjustment period, but isn’t that the way for every kind of roommate? As far as Denki is concerned, the situation with Katsuki is going about as smoothly as humanly (or caninely?) possible.
And then Katsuki’s rut hits.
At first, all Denki notices is that Katsuki is even more irritable than usual. He tamps down on his instinct to pry. After all, between his mandatory lessons to “integrate into society” and the frankly meager stipend he receives to tide himself over, Katsuki is probably dealing with more than Denki could even fathom. The last thing he needs is Denki shoving his nose into his business.
It isn’t until he attempts to confiscate a pillow Katsuki’s trying to fuck a hole into that Denki realizes something’s probably up. One second, his fingers are on the (frankly ugly) corduroy pillow case. The next, he’s snatching his hand back to his chest as Katsuki lunges for it with a snarl. For the first time, Denki is aware of the powerful snap of Katsuki’s jaws closing mere inches from his skin.
When Denki yelps, “What the hell, dude?” he doesn’t get a customary snippy response. Instead, Katsuki growls again, then ignores him for his pillow.
Denki doesn’t want to say he’s scared of his roommate, but…well. He’s not going to say it. He’s just going to incriminate himself via Google search history and make some phone calls.
After falling down some unexpected porn rabbit holes, Denki finally surfaces armed with three new pieces of information.
1. Katsuki is experiencing his rut, or what Denki refers to in his notes as a period but for boners.
2. The only way to stop Katsuki’s ruts is to get him fixed. As a man, Denki’s integrity won’t let him threaten another guy’s balls. (Also, he might’ve looked up the procedure and almost passed out.)
3. Letting Katsuki ride it out without interruption is the fastest, easiest way to get it over with.
Denki has always been a master of going with the flow. He doesn’t see any reason why this should be different. Between his night shifts at the club and Eijirou’s days at the gym, they never have to leave Katsuki alone and feral in the apartment.
They work well together, the three of them. Katsuki would probably brush him off if Denki said it out loud, but Denki’s grateful for his presence now. Deep down, he’s pretty sure Katsuki is grateful too. In his own way.
For months, Katsuki’s ruts are just another peculiar habit to adopt into the routine of their household. Denki gets used to them.
Then, Denki wakes up on the couch one day, squinting away the afternoon sun and vaguely aware that something is off. It isn’t too unusual that he fell asleep on the couch. If Eijirou isn’t still around in the morning to usher him to bed, Denki has the habit of knocking out on the first flat surface he sees.
He’s wearing nothing but his briefs, but that’s not out of the ordinary, either. Between sweat and spilled drinks, getting his sticky T-shirt and jeans off is always a top priority. Besides, the only one around to see him like this is Katsuki, and it’s not like he has any room to talk, not when he’s fully naked and pressed right up against him, hips rocking into Denki’s ass—
Hold on.
“What the hell?” Denki croaks.
The movement of Katsuki’s hips slows, giving Denki a few seconds to scoop his thoughts into something coherent. It’s harder than it should be. Sleep clings to mind and the hot weight of Katsuki on his back makes his head feel full of syrup.
There’s a snuffling, quiet whine in his ear and Katsuki’s hips twitch forward. Something hot and firm and big presses against Denki’s ass.
“Oh, fuck,” Denki gasps, a shiver running through his body. That’s—that’s Katsuki’s dick, it’s out and hard and oh, Denki’s hard too. He could probably blame it on being asleep, if he wanted to. It just wouldn’t be very convincing, considering how every shift of Katsuki’s body on top of him makes Denki’s cock twitch in his underwear.
“Katsuki.” Denki’s voice comes out rough with sleep and something else he can’t quite admit to yet. “Dude, what’re you doing?”
All he gets in response is another whine, louder this time. Shit, Katsuki must be far enough into his rut that he’s given up on human words. Denki should say something, should do something—
Denki takes a breath to speak, but it rushes out of him in a whimper when Katsuki shoves his face against the back of his neck. He pants, hot and humid, as he starts to shove his hips forward again. He must’ve been going easy on Denki before, because the powerful movement of his hips now shoves Denki down into the couch with every thrust.
Denki squeaks as his cock grinds into the cushions. The friction of his briefs is almost painful in exactly the way he likes. It reminds him of rough touches, of getting off against Eijirou’s thigh, of a hand working him well past orgasm and into tears.
It’s good. And Katsuki isn’t even trying.
Before he can stop himself, Denki tilts his hips back into Katsuki’s and rocks into the next thrust. He can feel the head of Katsuki’s cock catch on his underwear. It’s…different from the dicks Denki’s felt before. The taper and point at the tip are utterly novel, even if the precome smeared across his thigh is plenty familiar. Denki suddenly needs to know how that length would feel in his hands, in his mouth—
When Denki reaches back and grasps for Katsuki’s cock, the hybrid lets out a surprisingly high-pitched noise, almost a yelp. It melts into a low, pleased rumble when Denki finds his target.
“Holy shit,” Denki breathes. It felt big rutting against his ass, sure, but holding the weight of it in his hand is another story entirely. Katsuki is thicker than anyone or anything Denki’s felt before. When he twitches in Denki’s hand, drooling precome down his wrist, Denki’s guts twist at the thought of taking it inch by inch.
Katsuki tries to fuck the loose circle of Denki’s fist and growls at the lack of stimulation. His hips jerk forward harder, almost angrily, and Denki tries to spread his legs wider to accommodate him. God, Katsuki isn’t even inside, but Denki can feel the power behind those thrusts.
On the next thrust, Denki’s knee slips off the edge of the cushion. He doesn’t quite fall off, but it’s a near thing, and he knows from experience that their couch is less than ideal for actual fucking.
He tries to get Katsuki’s attention by patting his thigh. “Hey, slow down, let’s—oof!”
Katsuki is bearing down on him, growling in warning as he continues to hump Denki gracelessly—which, honestly, just won’t do.
“Knock it off!” Denki wriggles out from under him and flops onto the floor. Without pause, he pushes his briefs down and kicks them off somewhere to deal with later. “C’mon, get down here. The couch sucks for sex. And besides”—Denki roots around between the cushions and triumphantly brandishes the small bottle he finds—“now I can grab this.”
If Katsuki weren’t in rut, he’d likely be glaring balefully at Denki for suggesting he knows how to do something better than Katsuki does. Then again, if Katsuki weren’t in rut, they probably wouldn’t be discussing how to fuck in the sitting room in broad daylight, either.
But Katsuki isn’t in rut. So, the moment Denki presses his face to the carpet and reaches for his ass with slick fingers, Katsuki is scrambling off the couch like it’s on fire. He moves so fast that Denki thinks he hears the fabric rip under his claws.
“See how much better this is?” Denki coos, breath hitching as he smears lube over his rim. He was probably a little too eager with it and he can feel it dripping down his balls and the insides of his thighs—but then he sees the fat, red length hanging between Katsuki’s legs and realizes the more lube, the better.
“Jesus, you’re huge,” Denki mutters. He massages his fingers against his hole and lets out a shivery sigh as he feels himself loosen, already hungry to be filled. “I should probably—”
Before he can finish his sentence, he feels Katsuki’s furry hind legs bracket his calves as hands grab Denki’s hips. The slick glide of Katsuki’s cock against his bare skin knocks Denki’s breath away. Katsuki ruts against him uselessly, the tip sliding between Denki’s cheeks and thighs.
And Denki knows Katsuki is big, he knows he should be more careful, but there’s something about Katsuki’s feverish, whining need that makes Denki feel a little wild, too. So, he reaches back and guides the head of Katsuki’s cock to his rim.
Denki gasps as the tapered tip pops in easily. He has no time to adjust, no time to even breathe before Katsuki howls and shoves the rest of his cock inside.
“Oh, fuck!” Denki almost sobs, back bowing and hands curling into fists. It feels like Katsuki is splitting him apart and leaving him with nowhere to run. He’s pinned on Katsuki’s length, caged in by his legs, held still by strong, clawed hands.
It’s everything Denki could ask for.
When Katsuki pulls back and thrusts forward brutally hard, Denki comes. With the way Katsuki’s panting and rumbling contentedly, hands and cock unyielding, Denki gets the feeling it isn’t going to be the last time today.
Katsuki’s rut turns him into a beast. Long after Denki expected him to be finished already, he’s still pumping his cock greedily in and out of Denki’s ruined hole. He’s lost track of time, lost himself completely to the rough rhythm of being fucked like Katsuki owns him. There’s nothing but the feeling of Katsuki’s cock buried inside him and wringing out more pleasure than he knew he had to give. He feels bruised and tender, inside and out, and it’s good.
Denki is so preoccupied by Katsuki’s relentless fucking that he doesn’t hear the front door open.
He does hear it when Eijirou hisses in a sharp breath through his teeth. Using what little energy he has left in his body, Denki turns his face toward the door. Beyond that, he can’t do anything but drool and whimper as Katsuki doesn’t stop.
Eijirou is frozen, staring at the sight of his roommates fucking on the sitting room floor like—well, like animals. Only the slam of the front door swinging shut behind him finally jolts him into action.
“Jesus, you guys.” Eijirou drops into a squat in front of Denki. “Are you—is this—”
“’S so good,” Denki slurs, reaching weakly for Eijirou. “Nnnh, so big—Ei, please—”
“Fuck,” Eijirou curses. His voice sounds strained now, darker. Just hearing it makes Denki’s hole clench, earning him a snarl from Katsuki. “You really—God, you really like this, don’t you, Denki?”
“Uh-huh,” Denki moans. He can’t manage words anymore, his mouth hanging open uselessly and letting pathetic noises spill out with every thrust.
Eijirou reaches down to cup Denki’s chin. His touch is as gentle as he always is—to start, anyway. The callused pad of his thumb makes Denki’s lower lip tingle when he traces it, then slips it inside. Denki suckles on it happily, savoring the salty taste of Eijirou’s skin as he looks up through half-lidded eyes.
“You two are gonna kill me,” Eijirou groans, biting his lip. “You look so pretty like this.”
Denki mewls around Eijirou’s thumb. It draws another curse from Eijirou before he’s kneeling in front of Denki and shoving his basketball shorts down to mid-thigh. His cock is already filling out, and the familiar girth makes Denki realize just how empty his mouth feels.
Behind him, Katsuki lets out a low rumble and grabs him even tighter. Claws dig into Denki’s hips, little starbursts of bright pain that make Denki want.
Mustering up the strength in his wobbly arms, Denki lifts himself onto his hands and lets his tongue hang out. He can feel his own drool dripping down his chin. Fuck, he probably looks like a dog begging for a treat more than Katsuki ever does.
“Ei,” he whines. “Gimme, c’mon, I want it, I want it—”
Eijirou shushes him and swipes his thumb over Denki’s cheek—wiping away tears Denki didn’t even know were there. “I’ve got you,” he murmurs. His other hand feeds his cock into Denki’s eager mouth, angling it to slip in, deep and wet and easy.
Denki’s eyes roll back as he’s filled from both ends. He always loves the smell of Eijirou after he works at the gym. The heavy musk of his sweat clings to his dark hair and makes Denki feel dizzy. He’s full, so full, but he wants more. He shoves himself further onto Eijirou’s cock until he feels it in his throat, until the tears spill down his cheeks and drip off his chin along with his spit.
Denki can’t stop the thick, gagging noise that catches in his throat, but Eijirou is a pro at handling this by now. His head falls back and he moans, curling his fingers into Denki’s hair and petting him. “There you go, sweetheart,” he gasps. “Fuck, that’s good.”
Katsuki doesn’t seem to mind as Denki fucks his mouth onto Eijirou’s cock. If anything, he’s enjoying it as much as Denki is. He was rough with Denki before, but now his thrusts are downright brutal. Every breath is a pant or a growl or a yip, louder than Katsuki’s ever been (outside of scolding them, anyway). Denki swears his cock is reaching even deeper and feels even fatter.
With a growl, Katsuki shoves himself in and grinds forward like he’s trying to imprint the shape of his cock in Denki’s ass. And oh, that’s not Denki’s imagination. That’s definitely thicker, right there at the base—
“Holy shit,” Eijirou curses. His grip on Denki’s hair goes tight for a second, making him whine around Eijirou’s cock. “He’s got a knot, Denki.”
The words send sparks up Denki’s spine. God, Katsuki can get even bigger?
Eijirou must read the excitement in his eyes, because he laughs breathlessly and asks, “You want that? Want him to knot you?” He licks his lips, eyes lighting up. “Want him to breed you?”
And that’s too much to take, entirely unfair of Eijirou to exploit Denki’s kinks like that. Denki chokes on a moan and comes again without warning. The pleasure is more muted, diffused throughout his body and almost overwhelmed by sharp overstimulation as Katsuki and Eijirou both keep using him. He gags and tightens and shudders, his body entirely out of his control and at the mercy of his roommates.
The clench of Denki’s ass around Katsuki’s cock makes him gnash his teeth and snarl. He’s pulling Denki back now, trying to shove his knot into that tight heat like Denki’s just another pillow he’s humping to get through his rut. Denki feels tiny between the two of them, fucked back and forth on their cocks like a toy.
He feels even smaller when finally, finally, his ass starts to give way to Katsuki’s knot. In the blink of an eye, it goes from pushing against Denki’s rim to popping inside, so big that Denki can’t stop himself from going stiff and making a panicked noise.
Eijirou draws back, thick strings of spit stretching out between the tip of his cock and Denki’s fucked-out mouth. “You okay, baby?”
“So—big,” Denki gasps. It feels like he can’t get any air in his lungs, like every last inch of space inside him is filled with Katsuki instead. “It’s—he’s—hnn, Ei—”
Behind him, Katsuki is whining louder than ever, his knot fully buried in Denki’s ass. Even though he’s as deep as he can go, he keeps grinding his hips forward in desperate little motions, as if he could fill him up even more. With a frustrated little noise, he falls forward onto his hands and blankets Denki, plastered against his back as he continues to work his hips in tiny circles.
In this position, it’s impossible to ignore Katsuki’s more dog-like traits. The soft fur on his lower belly instead of the scratch of a happy trail, the smoothness of his tongue when he laps at Denki’s ear and neck, the inhuman grunts and whines—all of it feels new and different and a little taboo, and fuck, Denki thinks he’s going to come again.
“Fuck, you’re taking him so well,” Eijirou groans. He cups his balls, giving them a squeeze before taking his cock in hand and starting to pump it. “You look so pretty like this, so good—”
“Oh, god,” Denki moans. “Ei, it—feels like your whole hand, Jesus Christ—”
Eijirou curses and works his cock faster. “Yeah? Shit, you make it look so easy, like you were made to take it.”
Katsuki lets out a loud whine, drawing a surprised giggle from Eijirou.
“Oh, you feel left out?” he teases. His free hand reaches out behind Denki, probably cupping Katsuki’s face or petting his hair. “You wanna hear what a good boy you are?”
Denki chokes on his own spit when Katsuki’s cock drives in even harder. He can feel Katsuki’s legs starting to shake, can hear how his panting is speeding up.
“You’re fucking him so well,” Eijirou croons. “My pretty boys, yeah? You gonna fill him up for me? Gonna breed him?”
With that, Katsuki lets out a strangled howl and his hips jerk forward one last time. His cock pulses inside Denki as he comes—and comes and comes, practically pouring his release into Denki. The rush of wet heat in his ass makes Denki fall to his elbows as another orgasm wracks his body. God, he didn’t even know he could come like this, aching and electric down to his bones.
“Oh, that’s so good,” Eijirou moans, voice uneven as he fucks his own fist. “You did so well, that’s—fuck, Denki, can I—?”
Wordlessly, Denki tilts his face up and opens his mouth, tongue unfurling all eager and sloppy. That’s all it takes for Eijirou to come. His brow furrows and his mouth drops open on a strangled groan, but he keeps his eyes open and fixed on Denki’s face as he paints it with streaks of sticky white.
Denki’s eyes flutter shut as warmth drips over his cheeks and mouth. Slowly, he licks his lips, picking up some of Eijirou’s come and humming at the bitter taste.
“God, you’re gonna kill me,” Eijirou wheezes as he sits down heavily on the floor. “Death by dick. Holy shit.”
“How do you think I feel?” Denki rasps. He finally gives in and lets his body collapse on the carpet. Katsuki follows him down—not that he has much of a choice, considering his knot is still locked inside Denki’s ass.
“How did this even—?” Eijirou starts, but Denki shushes him.
“No questions,” he says drowsily. “Not while that”—he gestures behind him—“is still happening.”
Eijirou huffs out an incredulous laugh. “I—yeah, okay. Fair enough.”
Denki pouts up at him, drawing a quizzical look from Eijirou.
“You want something?”
“Come cuddle,” Denki replies like it’s the most obvious thing in the world. Which it is, really. At least, it’s what they’ve always done before. The addition of Katsuki just means Denki will be extra toasty today.
To his credit, Eijirou easily acquiesces and shuffles over to lie down by them. When he reaches out for Denki’s hand, Katsuki lays one of his over both of theirs with a gentle, gruff sound.
Eijirou sighs. “We’re…probably gonna have to talk about this, aren’t we?”
“Not while—”
“I know, I know.” Eijirou strokes over their tangled fingers with a thumb. “But eventually, yeah?”
“Yeah.” Denki knows he should probably be more anxious about it. Some distant part of his mind is cursing his habit of sleeping with the people he lives with. It’s easy to ignore, though, when he can feel Katsuki’s heartbeat against his back and feel the fondness in Eijirou’s gaze.
It’s probably going to be complicated—but just like every other complicated thing about them, Denki gets the feeling it’s going to be worth it.
