But in the end

A few hours later Ejiro and Denki walked into the greenettes room after classes only to find their other two mates cuddled up and sleeping naked under the covers of the blanket.
A blush spread over Denkis face and Ejiro chuckled.
"Looks like they made up." Ejiro said and bumped into Denki teasingly.
The omega giggled.

"I need to take a shower" Ejiro mumbled exhausted and disappeared in the bathroom right after.
Denki sat down on Izukus desk and started doing his assignments for classes, knowing that he takes longer than his other mates to understand certain stuff.
He was so focused on figuring out how to answer the next question on his sheet that he didn't notice one of his mates waking up or putting on pants.

Only when arms wrapped around him from behind he snapped out of his trance.
A familiar caramel scent hit Denkis and he leaned into the hug.
"I'm sorry." Katsuki mumbled, burying his nose in Kaminaris neck, inhaling the others scent.
Their omegas purred within them satisfied.

"I know." Denki mumbled and let his head fall back on Katsukis shoulder.
"How's he doing?" Denki asked after a while, standing up and leaning against the desk, pulling Katsuki closer to him.
"Exhausted." Katsuki mumbled.
Denki smirked, wiggling his eyebrows and Katsuki rolled his eyes.
"Not because of that. Because of what we talked about with Nezu." Katsuki clarified and Denkis smirk disappearing, replaces by a worried expression.
"How bad is it?" Denki asked and Katsuki frowned.
"It's bad." He said through clenched teeth. Denkis eyes filled with tears which Katsuki noticed immediately since they were standing so close to each other.

Katsuki could feel Denkis omega breaking down.
"Shhh it's okay." Katsuki said softly, drawing circles on Denkis back.
Denki looked up to Katsuki with teary eyes, pulling him closer if that was even possible.
"We can't loose him. I'm scared." Denki whimpered and Katsuki put his forehead on his mates.
"He wouldn't allow that." Katsuki said which Denki didn't expect the other to say.

We'll protect him.
He's gonna be fine.

That's what he expected.
But nothing calmed Denki down more than the words Katsuki chose to say instead.
Because he knew the other omega was right. Their alpha wouldn't allow his mates to go through that type of pain just like that.

Denki reached for Katsukis neck and pulled him down until their lips met.
Their lips started moving in sync and Denki buried his hands in Katsukis hair, slightly tucking on it while Katsukis hands were holding onto Denkis hips, slightly squeezing.

Katsuki never played with the idea of actually topping someone before. He liked to tease about it, but that's about it.
Or so he thought.
With Denki, it was easy to be the dominant one.
And when it comes to them being omegas, even biology didn't have a say in this.

Omegas being with omegas, alphas being with alphas. Of course it's possible.
Why wouldn't it be?
Being with the same second gender is just like before the second gender evolution even started.
Their second gender didn't matter in this at all.
Apparently Denki was just a bottom for all his mates and Katsuki likes to top Denki.

It felt nice that they weren't driven by biology for once. They welcomed this feeling because it helped them stay sane.
And it was reassuring.
Them being together was just fueled by their love, how refreshing. They separated from their kiss and Katsuki let his head fall on Denkis shoulder.

They just enjoyed the silence.

As long as it lasted.

Shifting sounds made them look up and they saw Izuku breathing heavily and grabbing onto the sheets with a painful expression on his face.
Katsuki and Denki quickly walked over to their alpha and started releasing calming pheromones.
"We're here. You can wake up." Denki said softly.
"Come on, Izu. Open your eyes." Katsuki said a little louder, softly slapping Izukus face. They know now that Izuku needed some type of physical 'shock' to wake up everytime. Katsuki just hoped that soft slaps were enough this time.
