After the deaths of Rui, the Lower Ranks 5, Yahaba, the Lower Ranks 6 and Susamaru, the Lower Ranks 3. Muzan was very frustrated and furious, so he ordered Nakime to summon the remaining Lower Ranks demon. Including Enmu, the Lower Rank 1, Rokuro, the Lower Rank 2, Wakuraba, the former Lower Rank 3 and Mukago, the Lower Rank 4 for a serious meeting.
Muzan starting to loses some faith on them so he thought that he would kill some of them, because they're too weak and they've loses his faith, so he asked 4 of them that should he keep them alive. First responses is from Rokuro, he said "My lord, I'm very loyal to my lord, if I had received more of my lord's blood, I'll be more powerfu—" Muzan saw the weakness and scurry in him so he instantly kill Rokuro. "As I expected, you're weaker than the Upper Ranks Demon, now who's next?" Then Wakuraba scared and tried to ran away, so Muzan kill him, leaving Mukago and Enmu to be the remaining Lower Ranks Demons. "Enmu and Mukago, I believed that you can archive my dreams and don't fail me like the other weak demons." Muzan said "Yes, my lord." Mukago and Enmu replied and bowed to him "Since the Lower Ranks are almost dead, I had found more demons to support my goals, so Serpent Girl will be the new Lower Rank 2, understand?" Muzan asked and said "Yes, my lord we're understand." They replied. Muzan orders Nakime to send Enmu back to his place, but Mukago is confused why. So, Nakime sent Enmu back and Muzan ordered Mukago to climb to his seat and gave him a blowjob.
Mukago climbed and took off his pants and his underwear, then. Muzan ordered Nakime to sent him and Mukago to his room, Nakime received the order and sent both Muzan and Mukago to Muzan's room. Soon after, Mukago started to rub his cock and licking it. Muzan said "Ahh…I'm glad that I'm still keeping you alive, Mukago. The others are just trash and useless, now suck it!" Mukago replied "Yes, my lord. I'll suck every drop of your delicious cum. Mhmmmm…Hmmm." 2 mins. later, Muzan ordered her to get naked and he's staring to take off his shirt to get naked as well, then Mukago is naked and Muzan is laying on his bed and ordered her to suck his cock. Soon after, he decided to put his cock inside her pussy and touching her boobs. "Aaaaaargh! It's so big, please fuck my hard my master! I wanted your delicious cum inside of me!" She moans and begs for Muzan's cum, then he started to fuck her harder. They're having for 2 hours and Mukago body is full of his cum all over her body, on her skin and inside her pussy and mouth. "Thank you very much, my lord. I shall not fail you, my lord." Then he kissed her forehead and let her go to wash up. Soon after she finished her shower and Nakime sent her back to her place to prepare for the Demon Slayer to arrived.
The End.
