So this is part 2 from this one-shot! I don't know if I write this story right, because idk anything about pregnancy. A friend of my helped me out. But still... I'm the one who needed to write it not her. 
(In this AU demons can eat human food.)

(POV Muzan)
I woke up and felt sick again. I ran to the bathroom room and vomit. After I felt better I got back to Koku who was still sleeping. I cuddled back to him and slept for 2 more hours. I woke up again, but this time not because I need to vomit. This time I woke up because I felt something moves next to me. I looked beside me and saw that Koku stands up.
"Oh your awake. Did I woke you up?" He asked worried. I shook my head. I stood up too and got ready. Today we wanted to tell the other uppermoons about it. After I changed I went to the kitchen with Koku. We saw many Uppermoons. I ate something and went to the meeting platform.(or whatever that is) many of the uppermoons got already teleported. Rui was there too. Kokushibo stand next to me and smiled at me. When everyone was there they looked as us. 'What is Kokushibo doing up there with master?' I heard Gyokko thinking. 'Now everyone gonna know it! I don't have to keep it for me!' I heard Douma thinking. So he didn't forget about it. I looked at Koku and nodded. We spoke about this. And we got to the point that Kokushibo should tell it, because I don't want to tell them. I was kinda scared of there reaction. "So Muzan and I wanted to tell y'all something. And please don't react like my brother would react." All nodded. "So with what should we start?" Koku considered. "Maybe with the second thing you two told us last night?" Douma said quickly. I gave him a death glare, but Koku just continue talking like Douma haven't said something. "So y'all know already, that me and Muzan were dating. Well not anymore" Koku said. Everyone looked at us in shook. "Because we're going to get married!" Koku finished his sentence. All uppermoons (+Rui) looked surprised but were happy for us. "Is there something else you want to tell us? Because Douma said the second thing." Kaigaku said. "Well... Kaigaku... how should I say that..." Koku began. "Ur gonna be a big brother" I finished his sentence. Kaigaku looked at me with a weird look, but then he just realized what I just said. The others realized it too. "Don't tell me..." Gyokko began, but couldn't finish. "Dad!! U f-cked Muzan-sama?!" Kaigaku screamed and Koku and I got red like a tomato. Everybody bursted in laughter. Only Rui looked confused. "What does that means?" He asked. Oh shot. I forgot how innocent he was. "Nothing important Rui." I said. I really don't want him to end up like Douma or Gyokko! "Kaigaku!! Don't say something like that when Rui is there!!" I said at him angry. "Ur not my mom!" Kaigaku answered impertinent. "But soon I'll be. And I'm the demon King! So learn some respect!" I got really angry right now. This boy. "Kai! Don't be so rude." Koku said. "Fine... can I have a hug?" He asked. Nobody said something but I looked at him with a snake smile. He went over to me and hugged me!! Awwwww!!! "Sorry Muzan." He said. Did he just called me only Muzan?! 'He just called the demon king by his normal name!' I heard Daki thinking. Koku looked at us with a smile. Then I looked back at Kaigaku and Hugged him back. "It's okay." I said soft. "Your all dismissed." I said to the other moons. Kaigaku stayed in my arms not wanted to let go of me. So we just stayed a little bit longer like that. I'm happy that he exempted me as a part of his family. I heard a sound and I was in my room a sleeping Kaigaku in my arms and Koku who was standing next to me. Wait. How did Kaigaku fall asleep that fast?! But tbh(to be honest) idc. I put Kai(yes I'm to lazy to write his complete name) on my bed and turned to Koku. "I'm happy that he excepted you, honey." He said with a soft voice. I nodded and hugged him. "Let's go to work, shall we?" Koku said with a smile. He kissed my forehead and went to his room, because he needed to do something important. I looked back to my bed, where Kai was sleeping peacefully. I smiled and sat beside him. I rubbed his back and was deep in my thoughts...

~Later~

(POV Kai)
I woke up, because I felt somebody rubbing my back. I opened my eyes and looked around. I was shocked. I was in Muzan-sama's Room?! Why was I here? I wanted to sit up but noticed that I was not alone in the room. Beside me was Muzan sitting. He was the one who rubbed my back, like Koku do it when I had a nightmare. "Oh... you're awake. Did you sleep well?" Muzan asked. I nodded but cuddled up to him. Why am I doing this?! He's my master! But at the same time he's my mother-in-law. He hugged me tight. I was happy about the touch. It feels good to hug him. My master... no! My mother. "You okay, buddy?" He asked kinda worried. "Yes I am... mom." I said still cuddling with him, but the I noticed what I just said. "I-I'm so sorry! I didn't mean to..." I couldn't finish, because he Stopped me with a hand sign. "It's okay. Soon I'll be your mom. Do you can call me like that." He said with a soft smile. I d as Miles back and cuddled with him again. He hugged me with a soft smile. At this moment I heard someone knock on the door. Muzan looked at the door and let go of me. He went to the door and opened it. Outside stand Gyutaro. Muzan looked at him and Gyutaro didn't even had to say something, because his eyes were already saying everything. "Kaigaku... Gyutaro want to tell you something. Go with him. I'm gonna go to work. Bye" Mom(yes Kai gonna call him mom now.) said. Then he was gone with a biwa sound. I looked at Gyutaro and stood up. We went to the forest to talk...
(And yes. I'm ending Kai pov now, because I'm evil 😈)
