#BkDk #SapThread (Older Queen A/B/O) Pt9

A good queen makes sacrifices.

First physically; blood, body, and safe heats are exchanged for a healthy kingdom.

Then spiritually; goals, dreams, and hopes sink into a murky abyss.

Izuku's done both.

But even the strongest heart wavers.

#BkDk #SapThread (Older Queen A/B/O) Pt8

Katsuki's been to courting events before. Despite Fuckface being a miserable king, he knows how important it is to keep a growing population. The princes all attend, dangled over the people like a delicious steak.

He never even thinks of mating.

Alright, I made you wait long enough! Who wants to watch our boys stumble through their feelings (and maybe one gets a little... clarity🤭)

Come join in on the fun!

Katsuki doesn't say it a lot, but Izuku is his soulmate.

The ring under his glove is the best thing he's ever done, being too smart to give anyone a chance to steal him.

And his husband sees him the same way.

But soulmates doesn’t mean its always easy.

"We have nothing?" Izuku asks, trying to hide his frustration while looking at the generals in his advisor's room. Despite having some of the sharpest minds in Trev, all lower their gaze from his question.

It's not their fault. Still, Izuku worries.

This is a 35 page chapter so... yeah. You're getting a lot of emotion, tension, and idiots in love.

Enjoy Retro Monday, and the new scene added in (Katsuki's so sneaky)

"We have a new neighbor moving in tomorrow."

At Shitty Hair's announcement, Katsuki scowls, keeping his gaze on the rice he's cooking. "So what?"

"Come on, you're not the least bit curious?"

He isn't. Not one bit. Katsuki knows how to mind his own business.

#BkDk #SapThread (Older Queen A/B/O) Pt6

Trev’s seasons change in mere days. Snow melts away. The temperatures rise.

It reminds him of Sange, a place he's only thought of when the nerd brings it up.

Because that was never home. But Freckles makes Trev feel like... something familiar.

I am so ready for the weekend, and I just popped on here to the cutest little BkDk art. So I guess we're all winning!

Enjoy the new chapter, and let me know what you think!

Alright, here you go! The Patreon exclusive College BkFemDk story you've been waiting for.

AKA Izuku has a twin sister, Ochaco. She's happy her sister is so popular, and doesn't mind being a 'nerd'.

So why does popular hockey player Katsuki keep trying to talk to her?

#BkDk #SapThread (Older Queen A/B/O) Pt5

Seven weeks after making his boldest decision since putting on his crown, Izuku knows sparing Kacchan was the right choice.

He's insightful, unafraid to say when he notices a gap or weakness in Trev's systems.

And Izuku thinks they're... friends.

Retro Monday is back with the second chapter of the Bff Big Brother story! A little more... 🌶️🥰

Katsuki doesn't know what to make of the queen.

After their conversation in the tunnel, the omega takes Katsuki into the barracks, letting him see his men.

He smiles, laughs, engages with the soldiers like he's happy.

Katsuki has doubts.

A bit late, but it's here!

Come check out my new Ao3 story, where Izuku learns a little (and Katsuki ALOT) about himself... through the power of panties!

"I should have known I'd find you here."

Izuku lifts his head from the irrigation schematics, his fatigue vanishing when catching sight of his visitor. "My King-"

"Just Toshi." The man who raises him gives a soft smile. "I'm here to visit my son."

Katsuki loses his parents when he's ten.

Before that, life's perfect. His mother's a seamstress, hot-headed and full of pride in Katsuki. His father is an amazing fisherman who gives Katsuki the best hugs.

He's happy. Loved. Then, the raid happens.

Also I probably should have let people over here know, but if you find it hard to follow all the updates on Threads, Ao3, and Patreon, I have a discord now!!

It's JUST updates. You can sign up for which ones you want, and I'll ping when I post.
