Mating Upper Moon 3: Various Yandere Upper Moons&Muzan X Intersex Akaza

Summary:

Akaza was unaware of the Upper Moons and Muzan being in obsessive love with him. When he hooked up with A Hashira the Upper Moons and Muzan got very jealous. Worse off they learn about his secret and they decide to make Akaze their mate~ He is the only demon that has a uterus after all.

(Akaza is male but has female reproductive organs in and out. Demons Can mate, but females cannot be turned into demons. So Akaza has a womanhood and he is the only one with it, so they all want to frick him and breed him. Demons can mate with human women, but human women never live long and cannot be turned into this au. So all of the upper moons and Muzan being yandere and their Darling Akaza can be mated to them. They won't let that go) (Daki is Genderbent to male)

(Non-Con and Dub-Con will be in this, cause demons and yanderes be sussy with consent, I will hopefully have warnings for chapters with full-on rape!)

Chapter 1: Secrets

Chapter Text

[Hello, My Sexy Muffins! I am back, back again! And Akaza~ Has fucked a friend~ I hope you all enjoy this chapter here it starts here now!]

(No One's POV)

It was a very well-kept secret, that all the upper moons and Muzan were in love with Akaza. Akaza was just a very handsome man to them and was sometimes downright adorable. Of course, Muzan made all his upper moon keep it to themselves. Muzan was also not able to admit his feelings for Akaza either. Although Muzan did desire Akaza, even when he was a human, and even more so as a demon. Muzan had to bury his desire for his favorite demon. Of course, when he learned something very very terrible it was a betrayal beyond words.

He felt his name being said by a human. He looked through Akaza's mind and saw a hashira. He did not know what his subordinate was planning. But he planned to find out.

"It is a shame you are so loyal to Muzan." The Flame-haired Hashira says as she puts on his shirt. "Even more a shame that you are a demon. If you were human I would make you my wife!"

Akaza growled at that. "Quiet, I am here for nothing more than a good fuck!" He snaps. "I lost my fight with you and I am a man of my word."

The Hashira nods. "Yes, but what would HE say if he knew you let a Hashira fuck your pussy." The Hashira says with a smirk.

"He does not even know that my sex and reproductive organs are female," Akaza says and Muzan's eyes widen as Akaza then turns to Marie and pulls up his pants. There between his legs was a stunning pussy, leaking the hashira's cum.

The Hashira walked up behind Akaza and wrapped his arms around his waist. "And what a beautiful sex it is~"

He starts to kiss down Akaza's neck and Muzan feels himself seething. "Mmmm~ Kyojuro, I have to go~ The Sun~" Akaza moans.

"Of course!" Kyojuro laughs. "The next time we meet, we will be enemies once more."

Akaza rolled his eyes. "That is if you can keep your dick out of me, I have no idea what gets into you or your need to pin me down and fuck me! You are a hashira! Act like it!"

"You are an upper moon~" Kyojuro mocks. "Act like it."

Akaza rolled his eyes once more and turned from the mirror. He opened up the window and jumped out. Running into the night.

Muzan felt his blood boiling, the only reason he did not call Akaza here was to punish him! Was only because the wheels in his head were turning. No woman, or any person with a vagina and uterus had survived being turned into a demon. Akaza is a man in everything but his sex and reproductive organs.

Muzan smirked as he now realized he could have his Akaza and more so that there was the possibility that he could have all his upper moons and he could possibly breed Akaza~ He would need to call an Upper Moon meeting without Akaza.

So that is what he did.

"Lord Muzan!" Doma asks worried. "Where is Akaza Dono? Was he killed?"

"Ah! Who would be strong enough to kill Akaza!" Hantengu cries out. "Truly terrifying!"

"I did not even get Akaza to model for me, and so wretched demon slayers killed him!?" Gyokko adds.

Gyutaro and Daki were silent and so Was Kokushibo.

"Akaza is not dead, but he has been keeping secrets from me." Muzan shares the memories he has with all his upper moons.

They all felt jealousy coil in their guts at seeing the worthless human kiss and touch Akaza. They all noted the way Akaza looked at The Hashira. The way he smiled and how his eyes were solely focused on the Hashira. It was like Akaza was lost in the eyes of the Demon Slayer.

But they also were shocked to realize Akaza had a womanhood and they were bitter to know that the disgusting human was the one who got to fuck it.

"I am changing what I said over 100 years ago," Muzan said. "You are all allowed to start to pursue Akaza now, we will all be sharing him, our goal is to make him ours and ours alone, He is to be OUR Mate," Muzan tells his men.

The Upper Moons were excited they now had the free choice to pursue Akaza. They all could not wait to get their hands on the pretty pink-haired demon~
