Enjoy.

Even though they had mated, his heat did not settle down just yet. As he had said it before, his heat will last a week though all Omegas are different. Either a week, or just a few days but most commonly a week.

Which meant Byleth had to mate him again and again for the rest of the week, just to satiate him. And also to prove his devotion to Zeldris.

Most Alphas back in the day would only want to breed. That is why he wanted to prove that he genuinely loves him, not just there to try to breed. Otherwise he would have discarded the charm a long time ago.

"Ah, Alpha... Alpha~"

Zeldris moans in ecstasy, laying on his stomach with his hips raised up for his Mate. He quivers from the feel of Byleth moving into him, letting out pleasured sounds for his sensitive areas being hit repeatedly.

The mint haired Demon kept going, hips up against his love with such vigor. The walls clenching around him drove him, the heat of his cove made him never want to leave. It adds the instincts to breed the royal demon he mounts on, which may of excited him more than ever.

Byleth opens his hazed dark eyes, eyeing where he and Zeldris are connected. He was still amazed that his entire length could go in so deep within, as though his body was made for him.

His Omegan body made to take an Alpha's length---HIS length.

"Taking me so well. Fuck, such a good Omega." Byleth hisses beneath his breath. The sweet scent intensified, as though coaxing him to keep fucking him and praise him.

The cunt tightens on him more, making him groan a little. Hearing him groan made the Omega prince keen loudly, and set a momentum to hear it again.

Then he whines, as he came onto his Alpha. The slick and clear fluids further soiled his inner thighs, already stained by the cum of his Alpha that escaped from inside of him. Neither of them cared at the moment, too lost in their instincts to mate continuously.

The knot then began to expand, making Byleth erratic with his pace. His hands gripped on the hips tightly, as he was breathing heavily to reach his limit.

"Shit... I'm going to...!"

"Alpha! Oh please cum inside me!"

With an animalistic growl, Byleth thrusts in one last time. His knot latched on, with his length proceeding to fill Zeldris further more with his cum. The Omega moans in delight, pushing himself back to feel more. He could felt the previous load leaking out, but he could care less.

He could never get enough.

The glow of the charm on his right wrist illuminates the room, only a little aside the flames of the fireplace. Byleth was thankful the charm is still in effect, because he lost count of how many times he came inside of Zeldris.

He leans over, and place a soft kiss on his lips which the raven haired male responded instantly. Both of them are exhausted for hours of fucking, but luckily today is the last of the Omega's heat. Which meant they can get their days worth of sleep.

Byleth woke up groggily the next day. He looks at the ceiling of his love's room for a bit, then down to Zeldris who is still sleeping. His quiet snores made him smile softly, before he proceeds to get up to bathe himself.

He walks through the doorway connected to the room, which revealed a bathroom. The tub itself is large enough for five people to fit in, seemingly carved into the stone. The water is steaming from the tub and spreads the heat, to which Byleth felt the moment he walked in and he did not waste a second to step in.

The heat of the waters seared his skin, but not enough to really harm him and instead welcomed it. With a content sigh, the Alpha relaxed for a moment to let his muscles become loose from the extensive activity that lasted a week. Then he went to scrub himself clean to wash away the grime and sweat and other bodily fluids.

There are scented ointments, mainly lavender and roses so he dosed himself in that. They may of smelled like Zeldris, but his natural scent is much more better than the ointment. Freshly cleaned up entirely, Byleth decided to linger in a little.

He leaned against the tub, arms resting atop with his head leaned back and his eyes are closed. He hardly had the luxury of hot baths, but damn does it do wonders to him. Especially after days of doing nothing but mate.

Then he sensed a familiar presence, purrs filling his ears along with someone coming into the tub. Hands cupped his face, as soft lips kissed his own.

Smiling, he responded back which made his Omega purr even more in delight. His hands wandered down to the torso of his love, as they continued to share kisses as a form of greeting for each other.

"Beloved." He heard him uttered lovingly to him, making him open his dark eyes. Byleth though became a bit awestruck, seeing that Zeldris did not tap into his demon powers which left his true eye color revealed and they are emerald.

Byleth knew green eyes are a rarity. He had seen it from his mother though, while he himself owns it but a shade brighter and more vivid. He never saw green eyes from anyone else, for as long as he knew.

He must've stared a bit too much, because Zeldris tilts his head at him a little with an amused look. Though he had a smirk on his face. "Take a painting, it'll last longer." he teased his mate.

"Your eyes..." Byleth said, still amazed by the eyes of the Executioner. Zeldris blinked at his response, then had his fingers lightly touch the lower lid, suddenly feeling a bit insecure. He never revealed his real eyes to anyone before and letting his guard down entirely.

"I... never showed my eyes to anyone unless I trust them. I thought since we're officially mates..." Zeldris explains before trailing off, averting his green eyes to the waters.

Byleth simply smiled, before he allowed his eyes unveiling itself from his demonic powers. This made Zeldris look at him, and looked stunned at the sight of his own pair of green eyes but much more lighter.

"You look lovely with your green eyes." Byleth tells him. His response was the raven haired man's blush, though a small genuine smile was formed.

"So do you." Zeldris responded.

After bathing themselves clean, Byleth left the castle to head back home. Before that though, he and Zeldris got into a feverish makeout since he craves mellow love. A nice change of pace since the kisses they shared most of the time was hungry and lust.

At home, Sitri was giving him an earful for not coming home for a week. She was worried sick something might have happened at his end. Though when the Beta saw that Byleth looked content, she can tell something good happened instead which eased her worries.

Not wanting to hide it, he told her he claimed his mate. Obviously his mother went teary eyed, sobbing how proud she is and how much he's grown. Though she was saddened that she won't be a grandmother soon when Byleth told her about withholding children, much to his fluster when he noticed that.

Soon, Bella and Jeralt were told about the news. Jeralt is stoically proud of his son and happy for him, since he was previously worried about Byleth not wanting to find a mate. It seems him meeting Zeldris of Piety would turn out to be life changing for the Alpha.

It was the same for Bella. She worries that Byleth would be by himself for the rest of his life. Hearing that Byleth not only found his fated Omega but also claimed him lifted all the pressure from her head. She wasn't sure if he took her advice on that fateful day when his dynamic was revealed or not, but at least he found someone.

Although...

Byleth strangely felt a void in himself. He should feel complete with Zeldris since he claimed him. But it only felt like he was only half complete, which made him realize he's missing a piece.

And he has a pretty good feeling what the missing piece is...
