Coincidence? Or fate?

Finally... what you all waited for!

⚠️!!bad smut warning!!⚠️

This is halfway my first fully time writing smut, so it's probably really bad- but her it anyways. I teased y'all way too long-
Hope you'll forgive me

(POV Koku)
I need him! I need him right now... I thought.
Something in my mind told me that since I  drank Muzan's blood.
I wanted to see him under me moaning! Sweating...I  wanted to mark him as my own and that my cum runs out of his ass!
I couldn't think straight anymore (we all know, that he never could 😏)
These dreams get just worse now!
I need him, but I don't want to r*pe him by accident.
I went to Muzan's room (nice) and knocked at his door.
It got opened by Muzan. He looked at me and then smiled.
"Hi Koku! How can I help you?" He asked friendly. I just went closer to him.
"What do you want Koku?" Muzan asked politely.
"...you..." I just said. He looked at me in shock and I could see his cheeks getting red.
He looked at me now red and softer.
"I-" he couldn't say anything, so he just let me inside of his room. He never let anyone in. What's going on now?
He looked me deep in the eyes and then he pressed his lips on mine. I kissed instantly back.
After a while he broke the kiss to breathe.
"Then take me..." he whispered in my ear while catching his breath again. I looked at him. Then I kissed him again. This time I slipped my tongue in his mouth. The kiss got more heated and soon we were in a wild make out. I felt like I was in heaven!
All these dirty dreams game reality!!!
I broke the kiss, so he could breathe.
I went on his neck and started kissing and sucking there. I left many marks and hickeys(?).
I heard Muzan begin to moan soft. It sounded like music in my ears (how...lovely).
After a while kissing I bit in his neck, getting  a loud moan out of him.
I took off my hario (?) top. Muzan looked at my upper body with lust in his eyes. Then he thrust me on his bed. I looked at him confused, but then I saw how he got on his knees in front of me. He slightly opened my pants and took my cock out.
I smirked at him, when I saw how he slightly began to lick my dick. First really gentle and only the tip, but after a while he took the tip fully in his mouth and began to suck at the tip. He took more and more in. He locked so slutty, sitting there in his knees, sucking me off.

(POV Muzan)
I don't know why I'm actually doing this, but I just couldn't control myself after I heard what he said. I tried to take his whole dick, but it would be too risky, since he's not only 8 inches like me- he was probably 10/11 inches. I felt his hand going through my hair, gently pushing me deeper. I let him control and continued sucking him hard and fast off.
He'll be the only one to see me like this. On my knees, listening to quiet groans, that escapes his lips.
"Mhm~ you're so good at this- it feels like your mouth was made for me~" I heard koku say and I got more red. I sucked harder. I wanted to taste him. But more I wanted to feel him.
After a while I heard his moans going louder. "I-I'm about to cum~ and you better shallow all up" I heard him saying. I was already planning on shallowing it, but now I won't be able to stop me from doing it. After some more strong sucks I felt a warm liquid in my mouth and I shallowed all. After I shallowed I took Kokus dick out of my mouth and looked back up to him. Then I stood up and sat on his lap, not caring that he didn't wear pants.
"Pls~ I gave you what you needed. Now give me what I want~" whispered I in his ear. He now looked even hornier than before. He laid me on the bed, with my back pressing down. He began kissing me again and left even more marks on my neck. He slowly began to take off my pants and boxers.

(POV 3rd)
Koku put his finger in front of Muzan's mouth. Muzan instantly took his fingers in his mouth and began to suck on them. After a while Koku took them out. He slowly began to press them against Muzan's entrance. Muzan began to moan quiet, but it got quickly louder, as koku pushed his finger in. He got slowly in and out and listened to the soft moans from the man under him. After a while he added a second finger and scissored him(?). The bottoms moans got needier. "K-koku~ please~" moaned the bottom out loud.
"Please what?" Teased the top.
"For god sake! Just fuck me-Ahh~" Muzan Said loud. The younger demon didn't actually expected him to actually say it, but these words just made him even hornier. He pulled his fingers out of Muzan and positing himself between his legs.
"Tell me when it hurts~" he said, slowly pushing his dick in.
"Ahhh~" Muzan moaned, the feeling of pain and pleasure overwhelming him.
When Koku were fully in he stayed where he was, so his master could get used to his size. After a while Muzan nodded and upper 1 began to slowly move in and out of him, earning soft minds from the older one.
"F-faster~ k-koku~" Muzan moaned and Koku went faster and harder.
(Save me god 😭)
After a while k. felt how he got closer to his climax and he could feel, that m. wasn't feeling better, since his inner walls got tighter. After more trust m. released and koku came soon after deep in him. (I just got really lazy-)
K. slowly pulled out and laid next to, now marked as his~ master and both soon fell asleep, not caring what for a mess both of them were.

That was soooo bad- at the end I got too lazy to write normally and just wanted to end it soon-
Hope you still like it- bye
