Cw: A/B/O Omega Kirishima Alpha bakugou Pregnancy Intersex omegas

After being in a relationship for so long, most birth control methods they'd started out using had long since been abandoned.

And to be fair, Eijirou remained on suppressants. Since presenting, his "time of the month" had always been a terrible fever dream, plagued by unbearable cramps and feral delirium.

It wasn't until he met Katsuki, an alpha whose scent could tame and soothe his omega that Eijirou felt safe enough to even allow himself to have heats.

And during his heats, when he was most fertile, they chose to be careful. Eijirou always took his pill, and during Katsuki ruts, the alpha forced himself to remember to wear a condom.

However-- just because Eijirou was on suppressants didn't mean he was incapable of getting knocked up by his heroic, 6'2, gorgeous, and insatiable alpha prime.

In the days leading up to his mate's long term stealth mission, Eijirou had been more than determined to bathe himself in Katsuki's scent. He /needed/ to be coated, to feel it reeking on his skin, sinking into his muscle and bone.

He wanted to be wrapped up and coated in satisfaction only Katsuki's sex could give him.

Eijirou allowed his omega to come to the surface and sing Katukis name while his mate fucked him through the head board. He allowd his omega to demand Katsuki’s knots, his teeth, his claws.

He gave into every desire, every time slick began to dampen his folds, no matter where they were, the floor, the bed, the kitchen, the car-- he needed it, wanted it--

Because he wasn't sure how long he'd go without this security, without this feeling of closeness, warmth and passion that intertwined them into the depths of each other's hsart and soul.

He was scared for Katsuki to be gone with no contact-- More scared than he allowed himself to admit.

If something happened, how long would it be before either of them knew? But this was part of their profession, right? They /chose/ this life, worked hard at it together-- and Katsuki wouldn't have been chosen for this mission if he wasn't one the /best/.

So as much as Eijirou wanted him to stay by his side, he /wouldn't/ keep his mate from his lifes work. Because in the end, was it manly to be a whiny, needy, clingy omega?

He shoved his secondary gender to the side, and sat up to meet the late morning sun creeping through the curtains. He reached to touched the refreshed claim bite at the nape of his neck, wincing slightly as the feel of dried slick tugged at his leg hair.

Katsuki was already gone, and Eijirou felt hisbheart swell as he noticed the simple note stuck to the bathroom mirror: 'Be safe at work. Don't do anything stupid use your shitty brain. Mina will check up on you. -- kat'

Eijirou left the note where it was and climbed into the shower. Three rounds of sweaty, over zealous "see you later" sex left him coated in a dried mixture of slick and cum hed been too exhausted to wipe away as he passed out against the soft rumble emitting from his alpha.

He resched for Katsuki's shampoo, coated his hair and instantly felt dizzy. Despite the mild, barely there scent, the smell permeated his nostrils to overwhelm him. He quickly washed it out, beginning to feel a little nauseous from the sudden assault to his senses.

Weird. He blamed his stupid omega for being so damn needy.

The week continued on, the sudden onset of a heightend sense of smell oddly fluctuating. He found that random things like garlic, fried foods and-- much to his dismay-- barbecue sauce hit him like a sledge hammer between the eyes.

And he was so tired after even a simple patrol or a day filling out paper work. He found himself barely managing to stay awake through dinner and a quick shower before collapsing into his nest and passing out by 7 or 8.

And it never seemed like /enough/ sleep. 10, 11, 12 hours? He still woke up groggy and achey.

A quick Google search revealed that he could be going through some kind of mate withdrawals-- his omega could simply be heightening his sense and crying out for Katsuki to come back.

But this didn't /feel/ like his omega. This was different. Infact, he found his omega to be oddly satiated, despite the physical aliments he was currently experiencing.

Katsuki would know. He /always/ knew. Actually-- he probably would've forced Eijirou go to the doctor by now. But he was fine, really. He just missed his mate.

Another week of fatigue, heightened smell and an onset of grumpiness passed and Sunday morning arrived. Eijirou resided to spend the day in bed watching crimson riot videos and relaxing.

Tw: vomit !!!!!!!!

But as soon as he opened his eyes to greet the morning and check for a sign from his mate, a horrible wave of nausea slammed against him like a freight train.

Eijirou barely made it to the bathroom in time, gripping the side of the porcelain for dear life as his stomach twisted and ejected last night's dinner onto the toilet with a force hard enough to make his ribs ache.

A pounding head ache set in as he dry heaved a few more times before finally finding the strength to stand again.
