Muzan Kibutsuji - SFW & NSFW Headcanons

[Note: Relationship Headcanons of Muzan Kibutsuji from Demon Slayer. Reader will be human and a regular citizen for this scenario. Will contain NSFW and slight manga spoilers (just one) so minors/anime-onlys, please do not interact.]

SFW:

Oooooo wee. Mr. Grumpy for a Living himself. Being in a relationship with Muzan can be.... interesting. It can be a lot of things. He can act "generous" and spoil you like a princess or just outright mean as hell. Either way, you'll be treated more as a pet/prized possession than an actual partner.

Muzan, or Tsukihiko, first met you while he was on a stroll with his beloved "wife and daughter." You were minding your business, and the demon just couldn't keep his eyes off you. Of course, the demon chastised himself for even looking at anyone like that, much less a mere human. But, longer he had his eyes on you, the more he wanted to know about you. So, he began planning your move into his castle and his life. This Demon King wanted his Queen. Well... to be more accurate....

He was in need of you.

From your point of view, you noticed Muzan's intense gaze on you that night. To say you weren't fazed by it would be a bold-faced lie. You tried to shake off his glare, but something within you made your eyes turn towards his. The shivers that enveloped your spine, the slight hitch in your breath and body language, none of it went unnoticed by him. Those ruby red eyes of his.... it's like they put you in a trance. One that made you want to know more about him.

The next time you saw Muzan was during a local event in your village. As you went to approach him, the alarm bells in the back of your mind began to ring. Your logic was telling you to stay away from this man at all cost. Deciding to put those thoughts behind, you approach the demon and introduce yourself. Muzan was a bit surprised that you made the first move, but all it did was make his plan of having you that much easier. Giving you a warm smile, he returned your gesture and bowed politely.

“It's a pleasure to meet you as well, (Last Name). I'm Tsukihiko. I apologize for my staring the other night.”

Such a suave liar.

From that day on, a steady friendship ensued between the two of you. Friendly trips to the market, hangouts at local events, night walks in the village. All of it made you come to like Muzan even more. To the point that those feelings became rather.... loving. Initially, you felt guilty for even developing them. The thought of being with a married father made you feel icky. But, being the oh so attentive person that he is, Muzan took note of your inner dilemma and immediately knew how to dissolve those worthless worries. All it took was a fake smile and gentle reassurance.

“(Name), I've come to sense that you're worried about Rei. Well, I can say that it is not necessary. We got a divorce as of recent, and she took our daughter with her. A factor of why is due to what I am.”

Muzan then told you about him being a demon. How he had to consume flesh to survive. This new information made you feel highly conflicted, to say the least. Before you could even process his confession, you heard a twang and found yourself surrounded by a multitude of buildings. You go to question him, but what you saw made your body freeze. Those ruby red eyes you fell for were now a harsh, blood red with slits. The caring Tsukihiko was really the ever atrocious Muzan Kibutsuji, the King of all Demons.

The devilish man stood in front of you, caressing your cheek gently, despite the look of possessiveness in his eyes. It was at this moment that you knew what you were dealing with. It terrified you, but.... it also intrigued you. It only made you fall deeper in love with him. Which is exactly what he wanted. “From this day on, you are mine, and mine only. No demon or man is allowed to be in your prescence, much less look at you. Such filth shall not matter to you. Ever. Do you understand.”

As most people say, Muzan has achieved the rich status and will pretty much spoil you. Anything you want, he's already at the place, cash in hand. That kimono you were eyeing? Already in the closet. A piece of jewelry you talked about getting? He's already putting it around your neck. This man has bought you so much stuff that you feel like a spoiled princess rather than his s/o.

Affection is very rare with him. He's not exactly the romantic type, but when he's in the mood for your touches, he'll just stop you from whatever you were doing and sit you in his lap. He'd caress your thighs and deliver small kisses to your neck. He would hold you tight, almost clingy, but these moments always made your heart flutter.

NSFW:

Now, you know this man is experienced. He's lived for over a thousand years, plus he had five wives in the past (though he treated them like complete shit). Muzan has the knowledge and skills to make the human body experience the ultimate pleasure.

If it weren't for Muzan's ability to hold himself back, he would've jumped on you then and there. The site of the soft ropes decorating the canvas that was your body made him aroused. He decided to heighten the experience by blindfolding you. The demon began to circle you, using the tips of his fingers to stroke the skin of your tummy, goosebumps appearing in their trail. He then moved them to your lips, letting them invade your mouth. You happily sucked on them, a soft moan emitting from you. An amused smirk formed on Muzan's lips.

“Such greed you have. Are you so reluctant to suck on my fingers? Perhaps my cock would be a better option for you then? Hm?”

It seemed his statement went straight to your core. As he stood in front of you and adjusted the rope to spread your legs, Muzan chuckled at the sight of your pussy drooling. Kneeling down, he delivered a series of kisses to your clit while sliding his middle and ring fingers in. To say you were a whimpering mess was an understatement. A combination of not knowing when or what he'd do, plus the feeling of his slender fingers, your cunt sang a song of joy for him.

Muzan is definitely big. He's definitely a good 9 inches and would increase its size to a 10. His cock has veins on both sides, and a pretty pink tip. You didn't know how you were gonna make it with a monster like that, but no worries. Muzan will make it fit. It's why this activity is done with you and you only. Your pussy is the only thing that's capable to handling him.

Your heart jumped a bit when you felt your body being suspended a couple inches off the bed. Was this man really about to fuck you stupid like this? Taking off his clothes, Muzan stood on the bed and used the tip of his dick to tease your entrance. You whined at him to stop the tease and get on with the show. A slap to your clit and the rough pace of his thrusts made you pause your complaint, your loud mewls ringing in the air.

“Cease your complaining. I'm the only one who gives instructions here. Are you that hungry for my cock that you decide to be a brat? To be so desperate as to beg me for it? So filthy. But nonetheless, I will gladly show you just how much I can offer this pussy.”

Muzan's favorite position is definitely between missionary and doggy. Missionary allows him to see you fall apart and mark your neck with his lovebites. Doggy, on the other hand, gives him access to smack your ass to his heart's content. He also loves to push your head into the mattress and fuck you harder. But, his number one will always be you on your knees, sucking him for everything's he's got.

Ya'll have more than likely fucked while he was in his female form. You never knew that tribbing could feel so good. And boy, was Muzan a master at the art. Crossed missionary, cowgirl, you did it all. Of course, she fucked you with dildos of all sizes. Some days, Muzan would overstimulate you with a vibrator attached to your clit.

“You can't handle anymore? How disappointing. You've only had four orgasms so far. Surely you can take more, my naughty girl.”

The overall lesson here? Muzan Kibutsuji is a god at sex, and you will always be left a drooling mess.
