Krbk, ABO, insecurity, FLUFF (optional smut at the end )

Omega Bakugou, belly round with his and Kirishima's pup, is in bed, shirt lifted up and resting just under his swollen breasts. Everything has been hurting and no matter what he does he's uncomfortable.

Not to mention the stretch marks that had started creeping in and marring his skin with harsh dark lines along his belly. He even saw them on his thighs and ass when he was looking in the mirror after his shower yesterday.

And he's so happy that he and Kirishima are finally going to be dads, fucking ecstatic actually. It's something they spent a lot of time talking about and when Bakugou voiced his concerns about how he was a shitty excuse for an omega--he doesn't have the typical nurturing

instinct, or the soft nature that most of his peers seem to have. He doesn't even want to take that much time off of work after their pup is born--Kirishima was quick to soothe every single one of them with exactly why he will make a great parent.

Bakugou sighs, his fingers skimming along the bumpy ridges on his skin and tries not to scratch at them, even though he really fuckin' wants to, because he read somewhere that that makes them worse.

What if after all of this is said and done...Kirishima won't want him anymore?

What if he thinks he's ugly now and moves on to find a better omega? One who doesn't look so gross and lumpy?

Tears prick at his eyes (thanks to the hormones flooding through his body he has been quick to cry at anything and everything), and he wipes at them furiously with one fist.

How embarrassing.

He hears heavy feet stomping up the stairs, and when Kirishima steps in the room Bakugou is quick to tear his shirt down over his protruding belly, hiding it from sight.

"There's my two favorite people!" Kirishima exclaims, excited grin plastered all over his face.

Bakugou merely grunts in response, avoiding eye contact with his husband.

Undeterred, Kirishima steps forward, crawling across the bed until he's towering over Bakugou's form on his hands and knees.

His nostrils flare and he leans down, pressing his nose along the column of Bakugou's neck, letting out huffs of air and licking at scar at the junction of his neck and shoulder. The scent of leather and vanilla washes over his skin and fills his senses.

A sign that Kirishima knows something is up but is giving him time to bring it up.

Bakugou's omega keens, and he spreads his legs a little, allowing Kirishima more room to get closer.

That mark is a reminder of what they are for each other...a forever bond.

No matter what.

If only his brain and the stupid pregnancy hormones could get on the same damn page.

Fingers toy with the waist band of his shorts and slip up under the loose t-shirt he had pulled on after his shower this morning. Before Bakugou can stop it from happening, Kirishima lifts his shirt up and places his hands on either side of his stomach.

There’s a reverent gleam to his eyes, and when Kirishima starts fucking purring, Bakugou knows he’s well and truly fucked. But he can’t...he can’t stand Kirishima looking at him right now...not like this. “Ei, come on stop,” he says, throwing one arm over his eyes.

He doesn’t wanna look at Kirishima’s stupid, dumb, adorable face right now.

Kirishima doesn’t pay him any mind though. Just purrs away, hands stroking whisper soft along the crest of his belly, and it’s too much.

“Stop!” Bakugou tugs his shirt back over his stomach, successfully hiding it away from Kirishima’s stupid puppy-dog eyes. “Don’t fuckin’...look at me, okay? I have too many marks now.”

The purring stops. “Kat, what the heck?” His sentence trails off and he stares down at Bakugou. Something comes over his face and Bakugou feels seen, and god damn his husband for being so fucking observant when it comes to him. “Ah, I see.”

He quirks an eyebrow at Bakugou and pulls the hands keeping the shirt down away with a sure grip.

“Oi. I told you to not--” Bakugou protests weakly.

Warm hands are back on his stomach and his vision is filled with the red spikes on top of Kirishima’s head as he bows down.

You are,” Kirishima’s lips press a steady trail, kissing along every stretch mark, soft sighs tickling Bakugou’s skin, “absolutely the most beautiful person I have ever seen.”

Kirishima’s nails skate along his side, pulling up on the shirt more until it’s pushed up and over his chest, bunching up along his neck.

Bakugou shivers when a quiet groan slips past Kirishima’s lips. Kirishima buries his face between the swollen tits in front of him, pressing the squishy skin against his cheeks and nuzzling it for a few seconds.

He pulls away and all Bakugou wants to do is push his head right back there, but he refrains. Bakugou’s skin is tingling at all the points Kirishima has touched him and he’s having a hard time feeling self-conscious. There’s a small, small, smile tugging at his lips.

“You look amazing, always. Any time, any day...you’re it, babe. But like this? You’re so soft and you’re having our baby, Kat.”

There’s a warble to his voice and if Kirishima doesn’t stop now, then they are both gonna be blubbering messes and it’ll be gross. Bakugou shuts his eyes.

Kirishima sets to work again, placing a few kisses along his breasts before moving up along his neck (paying special attention to their claiming bite), his cheeks, eyelids, nose.

He hovers over Bakugou’s face, their noses almost touching, and whispers, “Hey, look at me, okay?” And how is Bakugou supposed to ignore that request when Kirishima’s voice sounds like that? So tender and adoring?

“There is nothing ugly or unappealing about you. I love every mark on your skin. It’s a miracle I’m ever able to keep my hands off of you, baby. Do you understand?” He emphasizes his point with a final kiss to his lips.

Bakugou’s throat feels thick and he tries to choke back the tears that were welling up in his eyes, but he nods. His shirt is pulled down, and while that would have brought him comfort and relief earlier, it doesn’t do much now. He doesn’t need it to.

No, all he needs is the warm, earthy scent pouring out from Kirishima as he tugs Bakugou close to his chest, spinning them around so he can rest on his Alpha’s chest.

The purring is back. Bakugou can hear it rumbling where his ear is pressed against Kirishima’s chest and it urges his own purrs to spill out into their bedroom.

Then, there’s a series of kicks to his stomach which pulls an excited giggle from Kirishima. As they lay there together, Bakugou feels his eyes start to slip shut and the stress of the day starts to fall away from him. 

Kirishima loved him and everything was perfect.

Bakugou isn’t sure when he dozed off, but when he wakes up he’s no longer propped against Kirishima’s broad chest and there’s a heady smell filling his nose.

His sleep-addled brain doesn’t recognize it right away, but then it’s a rush of leather and vanilla everywhere; there’s even the faint traces of arousal in the air.

His cock twitches and he can feel his hole gush with slick. There’s a low groan and something wet probing at his hole. It’s all so much and so good. Bakugou moves his hand down his body and he can feel dried something on his skin, but he’s too fuckin’ horny to worry about that

right now.

He must have had a great fuckin’ dream or something. He gets to his cock, circling his fingers around it, but as soon as it’s in his hand there’s a low growl rumbling against his ass.

“Mine.” Bakugou opens his eyes for the first time since he woke up. He has to sit up a little to see, the fingers holding his thighs apart tightening their grip slightly, and there’s Kirishima.

There is slick all over his chin, some even dripping off the edge to soak the sheets below him, tongue snaking out to lap at the reminder of Bakugou’s arousal on his face;

his eyes are wild, darting between the still leaking hole, Bakugou’s cock, and his face. “You come with my mouth and my knot only.”

Kirishima’s head dives back down, probing at his entrance with his tongue, the growls and moans he lets out sending pleasure shooting through his body. “Taste so good, baby. So perfect.”

Large hands pull Bakugou’s legs even further apart, allowing him easier access to what he wants. Bakugou doesn’t fight it; a finger joins Kirishima’s tongue, poking at his sensitive hole, causing a high-pitched keen to tumble past his lips.

“Yes, holy fuck. I want more, alpha,” Bakugou pants out, bucking his hips and sinking down deeper onto Kirishima’s finger and tongue. “Ple-eease.” He can already feel his orgasm building again, a warm pressure building in his abdomen.

“I’m gonna come just like this if you don’t give me more, Ei.”

The finger starts moving quicker, the drag inside of him pushing him closer and closer to the edge. Kirishima slips his tongue out, head falling to kiss and bite at the sensitive skin along his thighs.

“Good. I have all night. Gonna come again just like this? Looked so pretty earlier when you spilled all over yourself.” His lips find a spot where Bakugou knows is a spider web of stretch marks because he saw them just yesterday and he sucks a pretty purple bruise there.

“Mmm. Beautiful omega.” A second finger slips inside of him and it’s great but it’s not enough. Kirishima smirks. “Come for me.”

That’s all it takes for Bakugou to fall over the edge, his orgasm shooting through him like a rocket and spilling his load, hot and sticky, all over his round stomach and tits.

“You’re so sexy like this, Kat. How many times do you think I can get you to come before I bounce you on my knot?”

Kirishima crawls over him, reminiscent of earlier, and licks a stripe along his stomach, cleaning up the cum that was puddled there. He moans, something low and guttural.

Bakugou can feel his cock from here and it’s so fuckin’ hard, precum already leaking from the tip and dragging along his limbs; if he moved just right, he could probably get the tip in, convince Kirishima that it’s what he really needed right now.
