Um.... I'm back XD
~~~~~~~
Byleth was the first to wake up before his mates, and kissed both of their foreheads before climbing out to take a much-needed bath. His rut with his Omegas certainly wouldn't be something he'd forget, and something that wouldn't be the last of it.
But fucking hell, he had fucked them like crazy and they were moaning messes, acting like true bitches in heat. The mint-haired hybrid did genuinely believe their heats had arrived again. They're that insatiable for him.
Still, he cannot believe they didn't hold anything against him for his... stupidity at question their loyalty to him. Of course they are very much loyal to him, enough to go against anyone who dared to try to kill him, their mate and Alpha. Even going against their father if he wants him dead. If Byleth had to be honest, neither Meliodas or Zeldris are very close with their father.
He only saw them as tools, and the fact they turned out as Omegas didn't make it any better. Course he's gonna use them by matching them to Betas with good genetics to produce a strong generation; he legit made them feel like they're only fated to become incubators.
Now that Byleth thought about it, it's no wonder why neither of them ever spoke of anything so... positive about the Demon King. Of course there isn't, just some fool who wanted his Clan to be the top over the Goddess Clan. And he treated his sons like they're his chess pieces to bring him victory.
And if Byleth had to be honest, he never liked him. Only obligated to follow because he's the King, it's not like he has any authority to go against him.
Speaking of generation...
Byleth furrowed his brows at the... mishap that happened during his week of rut with Meliodas and Zeldris. He didn't realize he had the charm tangled up in his fingers and had it torn off from the younger prince until too late. Chances of him getting conceived is low, but there's still a chance. And then after that, Meliodas instantly took off his own charm and took the knot and release with eagerness. And after that, too caught up in his Alphan instincts, they continued to mate without protection.
This made him thump his forehead against the wall of his bathroom, as the warm waters continue to awash his body he had recently scrubbed while deep in thoughts. As much as he certainly doesn't mind having children with them, but the timing isn't exactly right. But he doesn't have the will to get them to terminate while they have the chance. Even if they aren't even born or fully formed yet, killing his own children because of the fact the world isn't ready for them is selfish.
"If they actually do end up getting pregnant, I have to find a place for us to live in peace... away from the war." Byleth muttered to himself with a frown on his face.
That is the only option that can work, though that would mean leaving his parents and sister behind, and leaving the war without notice. But if Byleth had to be honest once more, he doesn't give a shit about the war anymore.
His possible, future children deserve to have a peaceful life. If the enemies caught wind of their existence, they would become easy targets. The mere thought of it angers him, his blood boiling and wanting to hide his future family away. After finishing showering himself clean, he changes into his long-sleeved tan shirt and dark pants before making his way downstairs.
The house certainly reeked of intense mating from his bedroom. He's gonna have to do something about it before his family comes back. It's a good thing his mother stored up some floral-scented incense, from her mishaps in the kitchen to the ruts he suffers since he presented. He might have to buy some(or better yet make some after watching how Sitri makes them herself) for situations like this.
He got some and placed them in various areas at a hefty distance so they don't overpower the rooms a lot, and got them burning and going with a snap of his fire magic. He also went ahead to tidy up the place since it was beginning to get dusty.
During the week, they have not eaten the food Sitri had prepared for them. Perhaps it slipped her mind that once the Alpha has their mate with them, they won't let them out even for a simple meal to replenish. Though, demons don't necessarily need to eat to survive like how humans do. But they do it anyways because the culinary is simply too good to ignore, especially the alcohol; a demon's favorite addiction.
Might as well put the food to good use then. He was no fantastic cook like his mother, but he did learn a few things from her. Nothing too fancy though, just some hearty beef stew to warm up his mates' exhausted bodies. He leaves the pot simmering, and made himself comfortable on the sofa to rest a bit.
He stares at the ceiling for a bit, his mind drawing blank as he waits for a certain amount of time to pass until the stew it ready to be served. That's when he suddenly got the feeling that he is not alone anymore in the room. Which got him look around, furrowing his brows.
There was no one.
Meliodas and Zeldris are still upstairs, and haven't woken up yet.
Byleth frowns even more at this. The savory scent coming from the kitchen area had him stand up to go check on the stew. But when he turns to make his way there, the Alpha was startled to see the sight of a person standing in his way out of nowhere. Almost like they just teleported there without warning.
It was a girl, with long dark green hair and equally green eyes, ears pointed and skin ivory. White and pink ribbons intertwined within the two braided hair strands, the same ones tied on the opposite of her wrists. She wears a golden headdress with purple tassels on them. She is wearing a purple regalia, ankle bracelets and barefooted.
'Who the fuck?!' was all Byleth thought at the sight of her, bewildered and on edge.
"Who are you?" he instantly demanded, wanting to know how she got into his house. And on edge in case she tries anything funny. She simply stares at him, her face unreadable.
Now that he looks at her, her entire being was illuminated. The fact he could not smell her natural scent made him realize he is looking at a phantom. A ghost of the girl with possible lingering regrets.
Or is he hallucinating?
And why does he get the feeling that he knows her?
Her lips then moved.
"...Beginning..."
"Beginning? Beginning of what?" Byleth tilts his head at her, frowning in confusion. She only stared again. And then, without saying anything else, she instantly fades away which made the mint-haired male widen his eyes.
He rushes over to where she stood, and looked around the place in hopes she would appear again. She never did, which left him annoyed that she pretty much left him in the dark about what she said.
And for some reason...
Repeating the single phrase within his mind over and over for a better understanding of the meaning behind it...
Caused immense dread to pool within his gut.
