Chapter Text
Katsuki had always prided himself for not letting his secondary gender get in the way of his dreams. Not that being an omega was a bad thing. No. He quite frankly didn’t care what secondary gender he was.
It didn’t change the fact that he’d be the best pro hero ever. Because what did gender have to do with objective skill?
But that was before.
Now though…
Now, he wanted nothing more than to be anything but an omega.
He looked down at the report in his hand, scowling at the wretched combination of words.
Two weeks.
Confirmed.
Pregnant.
No. This had to be false.
He couldn’t possibly be pregnant. He took birth control and everything, even used protection each time he had sex.
So how on earth?
He just went back to the top 10, a child would hinder the slow progress he’d been making and push his ranking back down again.
Sure he missed his last heat, but his heats had always been irregular since he first presented. Hero work and the constant suppressants made having a natural heat difficult.
But apparently pregnancy was still possible even when not in heat. Ridiculous.
What terrible timing to suddenly be pregnant.
He literally just went for regular bloodwork, but something in his gut told him to get a pregnancy test too, so he requested for it to be added.
And here he was.
It wasn’t that Katsuki hated kids.
No. No. It was quite the opposite.
He liked the brats, and had always wanted to have some of his own one day, when he and his boyfriend had enough money and stability to properly provide for a growing family.
This was too early though. He wasn’t mentally ready to be a parent.
Katsuki’s mind was running a hundred miles per minute. He was potentially growing his future child, and he didn’t even know what to feel about it.
Well, two months had gone by, so he needed to do something before the abortion period passed.
He also needed to confront the father of the child.
Somehow.
Hopefully.
He just prayed Izuku would help clear the storm that was his mind.
──────────────────
“Zuku. What do you think of children?” Katsuki casually asked Izuku at their shared apartment, after both of them had come back from work and were now having dinner together.
He purposefully waited until Izuku had settled in, he knew how tired his alpha got from working with kids all day, and he didn’t want to jump the gun immediately.
He himself needed the mental break too.
Izuku paused for a second, and looked up to face him. “I’m not sure Kacchan. I don’t have any thoughts about children.”
No thoughts? What was that supposed to even mean? Where was this all coming from?
“Would you ever consider having a pup?” He asked. They’d had the talk about pups before, back when he initially asked Izuku out. Back then, Izuku was pretty positive about them expecting, but he wanted to check if Izuku still had the same thoughts.
After all, it had been four years since they started dating, and Katsuki knew a lot could happen in that timeframe.
But Izuku was just silent. And that felt weird.
He wasn’t saying yes or no, and the look on his face was carefully neural, like he was thinking of what to say to him. As if he needed to be careful around Katsuki.
Which was ridiculous.
Stupid, dumb alpha. Katsuki could handle the truth. He wasn’t sensitive.
“Zuku.” He pressed, “You’re not answering my question. What is your opinion on pups?”
Again. Silence.
Izuku wasn’t even telling him to cut it off, just staying silent like a stupid dumb bastard.
It was pissing him off. Why was Izuku not saying a single word!
“Wouldn’t it be a good thing if we have our own pup?” He tried another approach. “You know. Having a bundle of joy that’s both yours and mine. Wouldn’t it be nice?”
He eventually got a reaction. Not the one he wanted, but it was something.
Izuku laughed. It was dry, more a cough than an actual laugh, and then his expression changed into his regular frazzled look. “Kacchan, can we not talk about this right now. This isn’t really a dinner table conversation.”
Katsuki paused. The response felt… odd.
He should ask. Push for more information, but a wave of guilt washed over him. Izuku looked dead tired, and the entire time he was sluggishly eating his dinner too. He felt like he was pushing it for the day, pushing Izuku’s limit a tad too much. “Okay.”
He’ll just ask another time. Because if Katsuki was something, then it was stubborn. If he wanted an answer, he was getting one. It didn’t have to be today.
──────────────────
Katsuki tried again a few days later. This time, he did it over the phone. “Zuku, have you seen that new show? The pup is adorableee.”
If Izuku didn’t like direct confrontation, Katsuki would take a different route.
“Which show, Kacchan?” Izuku’s voice was light and sweet, which was a good thing. If Izuku was in a good mood, then maybe he could wring out an answer from his man.
“The one I sent you a link to. You know, the family drama where the couple’s trying to raise their three kids with only one income. You know, the one where the alpha lost his job.” Now he was frustrated.
Was Izuku not listening to him or something? He always watched or at least kept up with Katsuki’s shows, because the omega loved discussing it with him.
“Ahh, sorry Kacchan. It’s just not really my thing. That sort of genre. Usually I enjoy your shows, but this one I’ll have to pass. Apologies.”
And Izuku just, hung up. Katsuki was stunned, to say the least.
Izuku didn’t enjoy lots of genres, yet he always watched it if Katsuki whined hard enough. He was weak against his pouts, and Katsuki knew and abused that knowledge.
What was so bad about this one though? He watched it, and it was pretty cute, not like some other shows he watched which were downright unbearable.
Still, he reckoned Izuku had his reasons. So he didn’t push it.
──────────────────
Katsuki tried a week later. He tried approaching Izuku again, but before he could open his mouth, Izuku grabbed him by the jaw and crashed their lips together.
Crashed was the only way to describe it. Izuku was aggressive with his kissing this time, sucking and biting on Katsuki’s lower lip.
Katsuki was half determined to push Izuku off, but the damn bastard was strong. Too strong.
Izuku’s hands slid down to his hips, and Katsuki yelped into his mouth when he was pulled forward, his crotch rubbing against his front.
Crap. Izuku knew how to play him. Just the briefest contact was making him wet, he could feel his slick start to gather and drip through his briefs.
He briefly shifted, moving his head back from Izuku, “Mmm… Zuku…” He breathed out, feeling a shortness of breath.
He’d been feeling nauseous recently, and Izuku sucking the air out of his lungs wasn’t helping either.
Izuku let out a low huff, clearly upset their makeout was cut short. “What’s wrong, Kacchan? Do you not want to do it?”
Did he? He’d missed Izuku’s touch, they hadn’t done anything sexual for a while, too consumed with work.
But as much as he wanted Izuku inside him, he wasn’t sure his stomach would like that.
Izuku was… well endowed to say the least, and their sex was most likely going to end up rough with how the kiss went.
Even though he had no idea what he’d do with the child, it wasn’t worth risking an early miscarriage.
“I’m not in the mood for penetration tonight. I wanna get off, but just…” His voice trailed off. Honestly, he hadn’t much idea what to do. He wanted Izuku’s something on him, but his brain was fuzzed out.
Izuku’s expression softened, and he kissed Katsuki’s forehead, “I can always eat you out. And if you want, you can suck me off.”
Hmm. The idea was tempting. Apart from missionary, they hadn’t engaged in other positions for a while. It was mostly because they both got really clingy after work, and missionary meant they could hug and look each other in the eye. It was comforting.
But maybe it would be a nice change of pace.
“Sure.” He found himself replying, too zoned out to notice Izuku. cling towards him.
Katsuki yelped when Izuku’s hands slid down to his thighs and lifted him up, grabbing onto the alpha’s shoulders to steady himself.
The sudden movement sent a wave of nausea through his stomach. He only hoped he didn’t vomit mid blowjob. It’d be so embarrassing.
Izuku walked them to the bedroom, kicking the door open and gently placing him on the bed.
Katsuki was certain they’d get straight into it, but he forgot how much Izuku loved foreplay.
Izuku pressed their mouths together before taking full control of the kiss. Usually, he fought back, but this time, he sort of wanted the dominance.
It was probably the hormones.
His breath hitched when Izuku’s hands slipped inside his shirt, tracing the curves of his waist and stomach.
Damn. His hands felt nice against his skin, the calluses adding to the sensation of being caressed, leaving goosebumps in Katsuki’s skin as Izuku’s hands travelled up.
His hands went up his abdomen, lingered around his rib cage, tracing the outline of each rib, before settling on his nipples.
Katsuki was super sensitive there, and Izuku knew that. He purposefully twisted and tweaked each nipple, swallowing Katsuki’s moans as the omega started trembling.
Izuku pulled back from the kiss to remove his shirt and tie, and Katsuki did the same, removing his shorts and boxers too.
Izuku also removed his pants and boxers, before going down on his might again.
Crap. He knew he was getting wetter by the second, so for revenge, he deliberately ground up against Izuku’s now bare crotch, hearing Izuku mutter a curse that was drowned by his own moans as Izuku pressed against him.
His dick was pressing against his folds, and crap, the friction was good.
The pressure felt nice, good. It made him feel dizzy. His head was afloat. His nerves were tingling. His stomach…
Wait. His stomach!
No. The pressure on his stomach could create complications.
Katsuki ended the kiss and abruptly pushed Izuku back, the alpha blinking as he stared at him, mouth agape like a fish.
“Something wrong Kacchan?”
Damnit. What would he say? Think. Think.
Ah yes.
“I wanna be on top. And I wanna get off now. Stop the dumb foreplay.” He huffed, trying to sound as mean as he could.
He didn’t want Izuku suspecting anything just yet, so he hoped he was convincing enough.
Izuku just nodded, “Sure. Move on over so I can get on the bed.”
Katsuki shuffled over, and Izuku got on the middle of the bed, and Katsuki moved to get over him.
He turned around so his back was facing Izuku, each knee touching each shoulder, his palms next to Izuku’s hips. Izuku helped him with the manoeuvring, getting him into place, and once they were comfortable, without warning pulled Katsuki’s hips down, his lips pressing against his pussy.
“Zuku!” He screeched, feeling the idiot smirk.
Fine. Since he wanted it that way. He grabbed Izuku’s erection, stroking it once with his hand before lowering his mouth, taking it in an inch at a time.
It was slightly hard, he hadn’t sucked Izuku off for months, and he forgot just how stretched his mouth was feeling.
Izuku was happily slurping away, Katsuki could hear how loud he was. Gross. It’s like he was drinking nectar when in reality, it was stupid slick.
Tuning Izuku’s nasty noises out, Katsuki focused on making him come as quick as possible.
For some reason, this position wasn’t the best either. His back was arched, and already he was feeling aches.
He was barely a month pregnant? Did body aches just start already.
Luckily for him, neither of them lasted long, too pent up from the few weeks of celibacy.
First was Izuku, whose release shot up his throat, and he had to breathe through his nose to not choke. He came soon after, accidentally biting down on Izuku’s dick and hearing the alpha yelp with his mouth still on him.
Once his orgasm was over, Izuku gently lifted him off, wincing slightly before attempting to kiss him. “Gross. We need to brush our teeth before I let that mouth of yours near me.”
Izuku grumbled, but obeyed, and they both walked to the bathroom to rinse and wash.
Izuku did a quick shower to wipe off any sticky residue, but Katsuki wasn’t feeling like it just yet, so he refused Izuku’s offer to shower.
“You sure? You look a bit tired.” The alpha was genuinely concerned, but Katsuki just waved him off, “I’ll be fine Zuku. Now just shower.”
Izuku nodded, and Katsuki made his way back to their bedroom, lying down and closing his eyes.
He woke up to a hand carding through his hair, looking up to see Izuku smiling, “Finished your nap?”
He just hummed, getting up and clicking his back. He felt… damp? Not sticky or anything, just damp.
Izuku seemed to notice, “Oh yeah. I wiped you down with a towel, didn’t want you feeling sticky.”
Katsuki found himself blushing, feeling pretty pampered. Being wiped down meant he could shower in the morning. He leaned forward, pecking Izuku’s lips, “thanks, I guess.”
It was only when Katsuki went to the bathroom to pee that it clicked. The bastard used sex to avoid the conversation.
And he played right into his hands.
He had multiple chances to say no, but then Izuku would’ve happily complied but also be suspicious, and he would’ve had to come clean about the pregnancy.
“Fair play.” He muttered to himself
Izuku might’ve been winning the last few rounds, but Katsuki will get an answer out of him soon.
──────────────────
Izuku was a sly rat.
He started avoiding Katsuki entirely.
Katsuki wanted to go on a walk to get some fresh air?
Izuku had tests to grade.
He wanted to go to the store to buy some food he wanted?
Another no.
He did that for a full week, ignoring Katsuki’s every request, always citing a halfassed excuse before dashing off.
It didn’t bother him. Izuku sometimes genuinely was busy, and as his partner, he needed to respect that.
But Izuku kept working so late into the night, Katsuki was always asleep by the time he came to bed, so they stopped actively cuddling too.
Katsuki blamed the studio pregnancy hormones. They were making him needy for no reason, making him crave Izuku’s touch, his warmth, his stupid alpha scent.
That night, once more, Izuku didn’t come to bed, busy grading papers in his study. He found a pillow, hugged it tight, and sobbed himself to sleep.
This sucked. He was constantly nauseous and vomiting, he was getting ridiculously moody all the time, and his idiot alpha won’t even give him a straight answer.
──────────────────
“So do you ever plan on having children?” He cornered Izuku this time round, on full attack mode, hoping this approach would actually get something out of his boyfriend.
Izuku was playing with his kindness.
Izuku groaned, having just returned from a jog, “Kacchan. This again?”
Katsuki narrowed his eyes. “Yes, again. Izuku. I told you I wanted pups. And you’ve been ignoring me for the past months and avoiding my questions! All I want is a yes or no answer, I’m not asking much from you!”
Katsuki didn’t know whether it was the pregnancy hormones or his own frustration, probably a mix of both, but he felt the sudden urge to hit Izuku somewhere.
Maybe it’ll smack some sense into him.
“Why are you so insistent on knowing?” Izuku voiced, staring at Katsuki with suspicion in his face.
“Why? Because I can!” He shot back, poking Izuku’s forehead, “Answer my question, or I kick you out of the house tonight.”
Izuku just looked at him like he’d grown an extra head, before his expression changed into something terrifyingly neutral. Way too neutral for the words that left his mouth.
“I don’t think I would ever like the idea of children.”
Katsuki froze, feeling a a coolness start to take hold of his body.
He blinked continuously, his brain trying to process what Izuku just said.
He didn’t want kids?
Why?
“I thought we agreed on pups when we were ready?” He quietly asked, his chest was starting to constrict, and his ears were ringing.
Izuku, apparently, didn’t seem to notice, “People’s feelings can change, Kacchan. I used to be interested in having pups, but I don’t anymore. It’s just how life goes.”
Just how life goes?
Katsuki didn’t respond. He didn’t know how to.
He couldn’t.
His throat was clogged up, as if blocking any possible words he could’ve spoken.
So he just nodded. “I understand.”
Izuku smiled, one hand cupping his cheek, “I’m so glad you do. My Kacchan’s the best, isn’t he?” He peppered Katsuki’s face with kisses, and the omega found himself giggling despite the heavy feeling in his chest.
During the night though, he stayed awake even as Izuku, for the first time in two weeks, was free enough to cuddle him to sleep.
Izuku didn’t want kids.
He didn’t want kids with him.
Katsuki was worthless to him. He wasn’t worth having a family with.
His emotions got the best of him, and all he could think about was how dumb and useless he must’ve looked the entire time, being giddy over a child when Izuku just didn’t want one with him at all.
It was probably an irrational decision, but the next day, while Izuku was at work and he was at home for a day off, Katsuki packed a few duffel bags with clothes, left his keys at their place, and left.
──────────────────
When Izuku came home later that night, he was greeted by an empty home.
“Kacchan?” He called out. Usually he heard the omega messing around somewhere, or in the kitchen making dinner.
But tonight there was no noise.
He removed his tie and shoes, putting how house shoes on before running around the house in search of his omega. Katsuki wasn’t in his usual spots of the living room, the kitchen, nor their bedroom.
He checked the study, nothing.
He even checked the bathroom, just in case Katsuki was showering.
But nothing.
His alpha was starting to get restless. The idea of losing his mate was starting to eat at him, and all he could think about was how to get him back.
It was then that he noticed a note, one from Katsuki. It was on the floor next to the omega’s side of the bed, so it probably fell off the side table when Izuku stomped around.
He picked it up, the ink smell was still there, meaning the note was recently left.
*I’m going to clear my head. Don’t bother me. I have a lot to think about, Izuku*
What?
Izuku scoffed. Did Kacchan just—
No. He refuses to believe it.
He ran around the house a few more times, convinced he missed a spot. Nope.
He then decided to take a lap around the neighbourhood. Maybe Kacchan was on a walk?
He went outside, walked around the pavements. No sign of a feisty blonde anywhere.
Izuku even checked the convenience stores nearby, but no sign of Katsuki there either.
It took him well into the night to accept the meaning behind the note.
Kacchan left him not long ago.
His omega.
Left.
Him.
