*this story's depiction of sex might not be accurate. it's hard writing a subject i know nothing about. but, hopefully it's not too bad.*

Ch, 5. Back to reality

Katsuki paced in front of the Midoriya's apartment building.

They had been back to the city for less than twenty-four hours, and Katsuki swore he was going insane without Izuku.

He didn't get any sleep that night. No matter what he did he couldn't get comfortable. He knew exactly why. He spent a whole week being spooned by his nerd, a whole week having his every carnal desire met, a whole week taking in the nerd's heavenly scent… he had gotten used to having him on him at all times. It felt weird not being around him.

"Kacchan? I thought we agreed to meet at your house." Izuku exited the main gate and readjusted his backpack.

Katsuki scowled. "You know I hate waiting and you were taking too long."

Izuku gave him a warm smile and grabbed his hand. "Sorry about that."

He really wasn't taking that long, Katsuki was just way too early. But, he didn't want to admit that.

He grabbed Izuku's hand and started dragging him to the school, hiding his blush.

Izuku fell in step with him. He was still shorter than him, but he managed to keep up.

"I couldn't sleep last night, so I read a bunch of information about omegas. I think I know enough now that I can play one convincingly. Even logged on to mom's medical journal site." Izuku began.

Katsuki became confused. "Won't you get in trouble for that?" So, his nerd couldn't sleep either? Was it because he missed him as well?

Izuku shook his head. "No, mom gave me the password a while back. She wants me to be well informed about medical stuff."

"Oh, ok." Katsuki looked back ahead, his blush getting worse. Could his little nerd be a future doctor? The image of Izuku wearing nothing but a lab coat and a pair of glasses invaded his mind… and he liked it. No, he loved it. Plus, doctors were kinda heroes too, so Izuku could live his dream of saving people. And Izuku could definitely rock a scrub.

"Did you know the average number of kids an omega has over their lifetime is 7?" Izuku smiled wide.

"7?" Katsuki almost had a heart attack. There was no way he would have seven kids. Two… three tops, but not seven! Hell, he didn't even really want kids, but he knew Izuku loved them and he'd probably want a couple. But hopefully he didn't want seven.

"It's just the average. Not every omega has that many. Some only have 1." Izuku's smile faded. "I read in the medical journal that most omegas don't make it to adulthood, but the reason why was redacted." He squeezed Katsuki's hand. "Most die at the age of 14."

Katsuki's heart dropped. He was 14. Could he die? He felt fine though. No. No he wasn't going to die. He was stronger than those other weak omegas.

Right?

He had to change the subject; he didn't want to think about it. "Speaking of kids…" He began.

Izuku was now beside him and looked up at him, still holding tight to his hand.

"How many do you want?" Katsuki couldn't look at him.

"Hm…" Izuku thought a moment. "I'd be happy with just one… if that's ok Kacchan."

One? That was all? He could handle one. "One's fine." Katsuki gave him a small smile.

Izuku sighed in relief.

VVVVVV

Izuku felt bad for lying about how many kids he wanted, but he knew Kacchan and kids didn't really mix. He really wanted three or four. But, he knew he'd be lucky if he had just one. So, he shouldn't push it.

Besides, what if they broke up? Sure, Alphas mate for life, but Omegas… Omegas didn't. Sure, Kacchan would have to get his mark removed, but if he didn't then he couldn't be with anyone else. And removing the mark would be an extremely painful surgery. Kacchan could move on, but Izuku wouldn't be able to. He read about that happening. The Alphas would die of heart break. And, Izuku saw that happening to him if Kacchan broke up with him. So, he really didn't want to scare him off. He really did love him even if Kacchan was only interested in him physically. He could live with that. But, he couldn't live without Kacchan.

He figured he should probably change the subject before the truth came out. "Oh, did you know if an Omega is Marked, then only the Alpha who marked them can smell them?"

"No, didn't know that." Kacchan looked back ahead of them and used his free hand to rub the spot on his neck.

"Also, only Alphas can mark Omegas. Betas don't have the biology to do anything." He continued. "And only boys can be omegas."

"Really?" Kacchan seemed to be listening.

VVVVVV

Katsuki half listened to Izuku. He knew he should be paying more attention snice he was an omega and didn't know that much about himself. But, he was still hung up on the whole dying thing.

He was too young to die. And he felt fine… for the most part. Although, something did feel off. Not bad, just… off. It was probably his lack of sleep the night before.

Izuku continued giving facts until they reached the school.

Nobody on the street paid them any mind and they mostly went ignored.

That is, until they stepped onto the school grounds and Katsuki's crew saw them.

"Bakugo?" One of those extras asked as they came up to them. "Why are you holding Deku's hand?"

Katsuki scowled at them.

"I'm Kacchan's omega." Izuku smiled convincingly.

The two extras began to laugh.

"Oi!" Katsuki barked at them. "I couldn't let some other low life alpha mate with Deku." He smirked. "I did him a favor. Besides, I'm sure only a villain would actually want his tiny useless and quirkless ass." He squeezed Izuku's hand a bit, hoping he'd forgive him for saying such things.

He'd have to make it up to him later. Everything he could come up with at the moment was sexual.

Might as well lean into it. "The nerd is sucking my dick. So you two are going to leave my little fuck toy alone. Got it?"
