------------------------------------------------------------------------

You were in the kitchen with Muzan per usual, and the two of you were making dinner for everybody. Usually, your family will get their own food but today, you and Muzan decided to bond by cooking and making everyone something to eat. It was peaceful and Muzan kept a hand on your waist or on your person at any given time. He really enjoyed the softness of your skin along his rough calloused hands. The contrast of his hands on your skin always left a trail of pleasant shivers, no matter where he touched you at.

" Babe, may you please hand me those baskets of spices over there, please?" You looked over to where he was pointing at and grabbed the baskets for him and handed them to him. He placed a gentle kiss on your forehead as a thank you and he continued to cook for your family. Even though your family was demons, you found out that they can tolerate some cooked human food, and today was a special occasion for that. Well, not really a special occasion, but they can tolerate it sometimes, so you just decided to cook once a week human food for everyone. 

" I am going to set up the tables and start calling everyone since you are just about done." He nodded in response as you left the kitchen area and started making various calls in the hallways, hearing your family, moving along the come to the kitchen. You enjoyed that all of you had a certain calling for different kinds of things from movie night to sleepover to eating. You went back in the kitchen to help Muzan serve the plates along the tables as everyone filed in and once everyone had their plate, you and Muzan decided to leave them be since the two of you had already eaten earlier in the day.

" Let's go to the library. I wanna see if we could find another book to read together." You smiled and nodded up at Muzan at the idea. He simply grabbed your hand and started guiding you to one of the various libraries that this castle had. This is what you liked the most about this castle. No matter how much you think you know, you always end up finding more and more stuff to look at and do. Once the two of you made it to the Library of his choice, he opened the door and closed them behind you and you missed how he locked it. You were too busy looking at the rolls and rolls of books, trying to think and figure out what kind of book was he going to be interested in reading with you.

"Muzan, do you have an idea of the kind of book you wish to read with me?" When you didn't get a response from him, you turned around only to let out a little gasp at the close proximity between you two. There was no space in between you. His entire chest was pressed up against your own front, as his two hands landed on your hips and held you tightly and firmly against him. 

"You should have known that I have no interest in reading a book." He smiled tilting his head to the side. His long, white hair, tickled the side of your face and neck. " I have read more than enough books with you. Not reading none will not be an issue right now." He took one hand off of your hip and trailed it up your side to cradle the side of your face nothing but love in his eyes. " The only issue we have right now is that I am not kissing you." Nothing more needed to be said as he gently pushed his lips against yours, humming as you reciprocated his actions. You honestly saw this coming with him, and you were just surprised that he lasted this long, without pouncing on you. You wrapped your arms around his neck to pull him in closer and you tilted your head to the side to get a better angle. You pulled away for much-needed breath and panted softly, watching as his pupils slowly dilated. 

" You are such a pretty demon. My demon." His pupils couldn't get any larger and in response to what you said, he dove right back in to capture your lips in a much more forceful and bruising kiss that had you moaning into his mouth. He swallowed every noise you made greedily until he got impatient and started trailing kisses along your jawline and down your neck to your shoulders. He frowned at the way your shirt was stopping him from getting to your skin.

"This is in the way." Without a care in the world, he ripped it off of you happy to see that you weren't wearing a bra. "Perfect." He did not have the finesse to try and be careful with your clothes since he was much more interested in what they were hiding. Without giving you a minute to really come to terms with that he ripped your clothes, latched his mouth onto your left breast, and used one of his hands to twist, tug and pull at your right nipple. 

"Oh, fuck yes." You felt him smirk as he alternated between each breast, giving them the same treatment with his mouth and his hand. " You're so talented with your tongue. It feels so good you're doing so good." His smirk turned into a grin as he removed himself from your chest with a wet plop sound.

" I'll do something even better." Once again with his hands, he ripped your shorts clean off, having already smelled your arousal through the fabric. He was salivating and shaking with excitement and anticipation as he stared down at your wet cunt. " Is this all for me? Ohh baby you shouldn't have. I'm gonna treat you so good for me for giving me such a treat." He reached down blindly, grabbing you by the back of your knees and hoisting you all the way up until he was at eye level with your wet cunt that was now dripping with arousal. 

'What are you-" You gasped when he pressed the flat of his tongue right on your slit and licked up stopping at your clit and focusing his tongue movements there. He was fast going left, right, up and down, and the firm hold he had on your hips and the way he had your legs resting on his shoulders ensured that you would not be moving anywhere until he was done eating. You let out moan after moan gripping his hair, being sure to massage his scalp whenever you were coherent enough. You felt your orgasm climbing up and up from the tip of your toes to the top of your head as his tongue never slowed down or speed up. "Muzan, Zaaaan-" You couldn't even speak correctly ss he took offense to the fact that you were still able to talk and decided to move one of his hands and slide two fingers inside of you, curling them up to hit your g-spot. 

"You can still talk?" He grunted at that latching his mouth back onto your clit being sure to scissor you and within a few moments, you screamed gripping his hair tightly and locking your feet on his upper back as your orgasm washed over you. " Look at that. Look at the mess you made. Such a good girl. You're such a good girl my love." He pulled away lowering you a little bit so that your cunt lined up with his hard dick. "It's my turn" You looked up at him still reeling and feeling aftershocks from your orgasm

"Wha- AH!" He had slipped in all the way to the hilt and using his hands guided you up and thrusted when he brought you back down. His pace was not slow or soft, it was hard and fast. "FUCK! AH, AH, TOOO-" You choked off to a moan his pace never slowing down. He was grinning at the way your eyes rolled back and your fingernails dug grooves into his shoulders.

"Look at my pretty girl getting fucked dumb. Look at you. Fuck I wish you can see yourself." He didn't want to let go of your hips so he grew an extra arm to grab you by your neck and force you to look at him. "You're squeezing me so tight, fuck your pussy is so warm and perfect." His words were getting to you and the way he was bullying your g-spot and cervix had a second orgasm climbing its way up rapidly  

"AH! AH! AH! CUM-" Muzan grinned a little sharper at your attempt at speaking. 

"You're going to cum or do you want my cum?" He didn't get a response nor did he expect one. He continued to fuck you just right but, let out a sudden hiss at the way you gripped him almost painfully and threw your head back with a mix between a sob and a moan. He felt wet and looked down to see you squirted making him growl. He started fucking you animistically chasing his orgasm "Oh-fuck, shit-FUCK!" With three hard thrusts upwards he painted your walls white breathing just as heavily as you. He stayed still until he was empty and softening enough to pull out slowly. He was sure to carry your limp form to the couch where he had snacks and water for when you were coherent enough.

"Muzan." You had enough energy to say his name and he shushed you as he smoothed your hair back and rubbed your lower back and legs. 

"Relax my love, I'm here. I'm not going anywhere." He pulled you in to lay against his chest before glancing up at the ceiling with a small smirk. "You'll need your energy for later."
