Demon slayer oneshots! (FEM! reader)

Muzan x Reader 🍋

(Warning:This chapter has lemon!) 

Y/n gulped as she bowed to Muzan upon the platform, next to the other fearful, sweating lower moons.

"Lowermoon 5 was killed... I'm talking about Rui." Muzan said coldly whilst in his female form.

Y/n gripped the wood tightly in fear. Her gaze dropped to the hard, cold wood beneath her palms. Muzan spoke.

"Why is it that you demons in the Lower ranks are so utterly weak? For over a century, the members of the Upper rank Twelve Kizuki remain unchanged." Muzan explained in his sexy, deep voice.

One of the lowermoons thought, "That's easy for you to say, but we..."

"That's easy for you to say, but we..." Muzan repeated, scaring the lower moon with black and ginger ass hair.

The demon froze, his heart hammered and sweat dripped from his face. Muzan could mind read? He didn't even know.... Y/n watched in surprise, her claws slowly dug into the wood..

" What? Go ahead and say it..." Muzan growled, his eyes pierced onto the stupid lowermoons.

After killing most of the lowermoons, y/n and Emnu were left. Emnu has blood splattered on his face. He blushed as his gazed was fixed onto Muzan. The demon king's gaze dropped to Emnu, his aura screamed danger. However, Emnu seemed to be entranced by Muzan's looks.

"Do you have any last words?" Muzan snarled as looked down on the lower moon, all he saw was something unsuperior to him.

Emnu sat up and smiled, putting his hands together like a prayer.

"Well, let's see..." Emnu smiled. "This is like a dream for me."

Y/n looked at Emnu in surprised and shocked. "This dude is insane!" Y/n thought to herself.

Muzan listened intently.

"To die by your hand in person!" Emnu said whilst spreading his arms. "And I so enjoyed hearing the other demon's last gasps!"

"Insane bitch..." Y/n mumbled under her breath quietly.

Emnu continued to speak, his gaze fixed on Muzan. Y/n wouldn't be surprised if the damn uppermoon simped for Muzan.

"Because I love to see others in despair and agony!" Emnu grinned.

Suddenly, a spike lodged into neck, which shocked the poor demon. He spluttered and choked as Muzan injected his blood into the lowermoon. Meanwhile, Y/n stayed still, only slightly looking over at Emnu and Muzan. Y/n blushed. Why was he so hot in both his male and female form!? Emnu collapsed to the ground. He writhed about in pain and agony.

"That's what I like to hear." Muzan seductively said, a smirk crept upon his face. "I'm gonna give you an ample share of my blood..."

Afterwards, it was only Y/n left. Suddenly, the sound of the biwa rung in the air. She opened her eyes to realise that she was in a room with a large, king-sized bed. There were candles lighting the place up and a pair of handcuffs near the edge of the bed. She shivered as she felt Muzan wrap his arm around Y/n's waist. Muzan was back in his male form. Slowly, Muzan's hand crept towards her ass, before he spanked it. She whimpered. Muzan grinned and nibbled on her earlobe.

"Hello, dear~" Muzan seductively said. "You may be useless and weak when fighting Hashira, but that can be quite different in bed, can it not?~"

Y/n heavily blushed as he threw her onto the bed.

"L-Lord Muzan!" Y/n yelped, "What are you doing?"

"What I've always wanted to do~" Muzan crawled onto her body, straddling her hips.

His lips crashed into hers. After a few moments, Y/n reprocriated the kiss. Muzan's hands explored her body as his tongue demanded entrance. When her lips stayed closed, Muzan's hand slid to her breast and squeezed the flesh. This caused Y/n to sigh in pleasure, this granted Muzan to access her mouth. His tongue explored her wet mouth as he unbuttoned her shirt. He discarded the piece of clothing onto the floor. He then kissed her neck. Muzan sucked and bit the flesh there, which gave her a hickey. He then ripped off her bra, pants, and panties, leaving her naked. Muzan's gaze explored her body. Fortunately for him, she was his, and will always will be.

Muzan then undressed himself, discarding his clothes. His pecs and toned muscles were all on display. Y/n looked upon his muscular build. Oh, how she wanted to just run her hands across his chest... Muzan then travelled down her body. She gasped heavily in pleasure when she suddenly felt his tongue exploring her folds. She moaned and grunted as Muzan's wet tongue stuck inside her womanhood. She gripped his hair, keeping him in place. He sucked and licked her nub and clit hungrily. Y/n gripped the sheets of the bed as she bucked her hips a bit. Muzan grabbed her waist, keeping her down.

"Stay still, baby girl~ Or I'll have to punish you~" Muzan purred against her.

Suddenly, Muzan got off her and stood up. He grabbed her hair and shoved her onto her knees. Y/n grunted in slight pain as she came face-to-face with his massive cock.

"Suck~" Muzan commanded harshly....

(Cliffhanger! Yeah, I'm so fucking tired so I'll be doing part 2 tomorrow. Sorry guys!)
