Fuck Off Deku, It's Mine!

A/N: Found the perfect pic for preggo kats :>

Katsuki clutched the sides of the toilet as he vomited his guts out. This has been happening every day for six weeks. His mate, Izuku gets frantic whenever he does. Katsuki blamed it on the Alpha because he's the one who's been cooking for them for a month (because that lump of shit lost to a bet) and you'll know why when you taste his cooking.

His throat burned and his voice was hoarse. He'd been denying the lingering thought on the back of his mind that it wasn't just Deku's cooking that caused this (even though his food tastes like shit but okay).

Today he had a day off which was pretty rare for them to have since they're the number one and two heroes. The very same day he hid in the bathroom holding a pregnancy test in his trembling hand. It showed two clear red lines.
Katsuki rubbed his stomach as if a bump was already there.

"I fucking knew it." He muttered. The Omega doesn't know whether he should be happy or upset and that fucking dumbass of an Alpha who relies heavily on pills and not wearing a fucking condom when doing it in his HEAT.

He wondered for a few more minutes of how he would tell Deku once the nerd is home. Wouldn't be possible to hide it since they've been dating for six years and Deku will eventually know something is up. He wants to keep the kid, he really does but they're still young. They both have a long way and bright future ahead of them. He stood up from the toilet and wandered outside only to hear keys jingle from outside.

Guess there's no turning back now...

"Kacchan? You there?" the sound of his mate's voice was dull, his heart beat thumped loudly. Katsuki inhaled deeply and thought about how easier it would be to tell his Alpha that he's pregnant when they're not even married yet, than to tell Deku that he "accidentally" broke his Limited Edition Ground Zero Winter Special figurine (he got pissed just by looking at it, why have the figurine when you the original one is your mate?).

"Kacchan? I can smell you from here, are you okay?" The Omega clicked his tongue, curse him and his dog senses. "You're home early today." He responded as he got out of his hiding spot. The Alpha literally lit up when he saw the blonde and pulled him in for a kiss in which Katsuki returned with ease. "I could smell your distress pheromones from the door. Is something the matter?" Worry on Deku's voice is evident. Bakugou still contemplated on dropping the bomb on the Alpha when he just got home so he pulled away and excused himself to go to the kitchen to cook something for his Alpha. Midoriya was sure something happened today but he decided to not ask until they've finished eating dinner.

(ó﹏ò｡)

"Kacchan." Izuku started a conversation when he noticed the thick tension in the room and Katsuki's distress pheromones skyrocketing. Katsuki stopped washing the dishes and turned to look at Izuku. "Did something happen earlier? You've been releasing distress pheromones since I got home." He fully turned to look at the Omega who stared back at him. "God damn it. Deku, I swear to any gods out there I'm throwing you out if you say something stupid."

"H-huh? Why??"

"Just shut up for a minute and let me talk."

Deku nodded obediently. Not sure why but Kacchan's voice seemed...anxious for some reason. He watched as the Omega inhaled deeply and shifts anxiously.

"Deku, I'm pregnant."

Izuku froze on the spot. Eh?

He searched high and low for any "I'm just messing with you nerd, don't think too much" but his eyes never lies. Kacchan looks so anxious that he's sweating too much (He's also afraid that Katsuki might blow up, literally). Is that why he was acting so strange earlier? He noticed that the blonde was now looking away from him. Why is he- oh....ohhhhhh. "Kacchan, c'mere." He said in the most gentle voice he could muster. Saying that made Katsuki's eyes light up and Izuku's heart squeezed at the sight. His Omega is really adorable when he's docile or nervous. Katsuki did what he was told and approached the Alpha who embraced him as if he's the most precious thing in the world. "Why'd you look so anxious saying it Kacchan? Hm?" he whispered on Katsuki's ear. "Why do you think? Deku we're not even married yet! I'm....I...I thought you would break up with me and...and you- this...This is unplanned! You-" Izuku took the chance and kissed his Omega to shut his rambling. Izuku was also the one who broke off the kiss and looked at Katsuki straight in the eyes and at the same time releasing calming pheromones to calm the stressed Omega down.
