One request // Doma x Reader

You are mine

After our night of intense passion, Doma was right. My legs felt numb and weak and I found it difficult to stand, let alone walk when I tried to get up in the morning. When I grabbed onto the bed frame to steady myself, my legs gave out from under me as I fell back onto the bed, waking up Doma from one of his rare moments of sleep.

"Well, good morning darling. You can't walk I assume?" He said with a small laugh on his face as he came to my side of the bed by crawling over it cutely. His majestic eyes were staring at me with lust and love as I looked around our room, completely littered with our clothes scattered and torn to threads, furniture broken, and the smell of sex in the air. He wrapped himself around me from behind as he gave me sweet kisses along my ear and neck.

"Yes, you are right. I can't walk right now. But I wouldn't change anything," I said calmly, feeling a blush cover my face as Doma smirked in amusement at my reaction.

"Just stay in bed today, you don't need to get up today. I'll take care of you, okay?" He said with a happy smile. I smiled at his kindness as I put my palm on his cheek, pulling him into a gentle kiss. "Careful~ it's hard to control myself around you, even for one day," he warned as I smiled at him coolly.

Sure enough, he tucked me back into bed with fresh clothes to stay warm. The fall was turning to winter and it was becoming cold so he made sure to install a fireplace in our room a few weeks ago so I could stay warm. He left for a short while and came back with a tray of food his worshippers prepared for me.

"Thank you, Doma," I said through my fatigue. Even without asking, he knew what my body needed and it swelled my heart to dangerous levels as he beamed a bright smile with his captivating eyes.

"Of course darling! You are mine after all, I need to take care of you," he said in his normal cheerful voice. Even if it was a facade most of the time, I always loved his voice. The way he called me his made my heart beat faster but I could sense his genuine love for me when he spoke to me like that. It was bizarre, he was a monster yet, he took such care of me like no one else had ever before or likely ever will. I couldn't help but be grateful to be his wife now.

As I went to kiss him again, he suddenly vanished into thin air. I was getting sick of these interruptions and that stupid musical note I now recognized as a Biwa.

Doma's POV:

-------

I was called back to the infinity castle by the Biwa woman yet again. I felt frustrated as they interrupted my time with her yet again, but I knew these visits kept Muzan from reprimanding me for growing such a bond with a human. As I looked around though, I noticed the other moons were here, meaning one of us was likely killed.

I destroyed some of the lights with my blood demon art when I heard Akaza talking, looking for the upper one moon as I reached out from behind him, placing my hand on his shoulder.

"You are beginning to hurt my feelings here Lord Akaza. Here I was worried sick something might have happened to you," I stated, feeling like my usual self. I never felt emotions for anyone as I did for her, but no one needed to know that.

"Get it off," Lord Akaza stated as I let out a "hmm?". He suddenly punched me in the jaw, knocking it clean off. He was slightly stronger than the last time, but at a slow pace of building strength to me still.

"That was quite a punch," I complimented as our meeting started with Muzan informing us of upper six deaths. I apologized but Muzan met me only with the same disdain he always had for me as he asked for any update on the blue spider Lilly.

"I'm afraid detective work is not my strong suit," I said casually, swaying side to side. I knew he couldn't kill me because of the baby, not like he would before anyway due to my power. My strength didn't come easily in this world.

"Just be useful for me for once and if your child ends up being immune to sunlight, bring them to me immediately," Muzan ordered as the other moons looked at me in shock. I repressed my thoughts for now about defying his orders because I knew he might kill for insubordination if I refused.

"Lord Muzan, how can Doma have a child coming? I thought all demons were infertile," Akaza called out in confusion.

"Since you are so insistent on knowing, he impregnated a human woman. You will guard the mother from any demon slayers when she births in a few months. We don't know what kind of energy something as large as a demonic birth could give off alerting the demon slayer corps," Muzan ordered before he tipped his hat at us, walking backward almost as if he was gliding until he vanished into thin air. How strange he has been lately.

Akaza turned to me with a look of hate in his eyes as he brought his hand to my neck. I was finding myself in this position often lately as I looked at him with a smirk.

"How did you impregnate a human? Why? You shouldn't touch women at all, but to force yourself upon one?!" Akaza asked with hate in his eyes as he squeezed me tighter. I let out a laugh as I patted his arms, angering him more.

"Who said I forced myself on her? For your information, she asked me to before her impending death. You met her already, you know how strange she is," I said as he finally relaxed his grip, but not before smacking my head off again so I couldn't talk for a moment. This seemed to irritate Lord Kokushibo who cut off Akaza's hand with such speed it impressed me while he lectured Akaza for disturbing the hierarchy.

"It is quite alright Lord Kokushibo, I could have dodged if I wanted to," I clarified as I regenerated my head with a smile.

"How did you impregnate human Doma?" He asked me without looking towards me. So, no one else knew it was possible I see, even if just a theory.

"The same way a human does. However, male demons are able to retain part of their fertility according to Muzan. It was just a theory, until I tried it," I casually explained, standing up as they looked at me in shock.

"So, you child, is it human or demon?" Akaza asked before I shrugged my shoulders at him.

"My, my, you are interested in my life! How exciting! It shows tendencies of both. It will be half, but likely different from anything seen before. We have to wait and see," I explained with a smile as I saw Akaza's face twitch in annoyance. I put both of my hands by my face and tilted my head to the side. "And how exciting, you will be there for protection so I can focus solely on her delivery. It will be a great day for sure!" I said with excitement.

"Only because Muzan ordered it," he said before vanishing as well as Lord Kokushibo. How sad, I barely got to see them.

I was teleported back to my room where she lay in await for me as a smile came across my face. When I approached, however, she was unconscious again and unresponsive as her stomach was swelling yet again.
