Kimetsu no Lemon

Yorimu

Yes I love this ship. But more importantly. This is basically a what would have happened if Yorichii would have found Muzan attractive. In this Au however some things won't work so smoothly so beare with me as it is going to be a long chapter again. Side note, Yorichii is here 25 and Muzan is about to turn 50 (yes I made him younger).

Warning this one-shot will be darker than the others so far so read with caution but there is smut. And not too little. And there will be a lot of timeskips. Also contains M-preg.

Now enjoy!

Yorichii towers over the Demon King, Katana drawn to that man's neck. But he couldn't. He, the strongest Hashira, the pride of the most feared Samurai, he could not kill this monster. Something in him stops him from doing so. Meanwhile Muzan looks up at the Hashira infront of him with pure terror in His eyes. <What is he waiting for. I know I can't survive him so why is he waiting. Does he want to torture me? Or his he debaiting if he wants to humiliate me before killing me off?>, Muzan thinks and slowly losing himself to his thoughts. Yorichii then, suddenly, sheats his Katana, ,,Get up." Muzan obeys. He fears what that man can do to him. Yorichii then turns around and starts walking, ,, follow me or I am killing you."

The Demon immediately obeys silently following the redhead. They walk for an hour before Yorichii opens a door of a fairly pretty house. ,,Aniki! I am home, have a visitor and a problem. Can we talk privately quickly! And no violence please", Yorichii yells into the house and two seconds later a man looking the same as Yorichii came into view, ,,Su- YORICHII THAT IS A DEMON!" ,,I know Aniki... Please let me talk to you first. Then we can still kill him!", Yorichii exclaims sounding a bit desperate. And he is. He is desperate to find out why he can't kill this one demon. Why can't he bring himself to just behead him as he does with all the other numerous demon he encounters. Mitsikatsu, the other man of the house sighs, ,,Fine. But only because your my little brother." Yorichii slightly smiles at his older twin before turning to Muzan, ,,Wait here at the door, don't move, don't touch anything and if you try to run, I will catch you and make it worse." ,,Y-yes sir...", Muzan wispers afraid that he might get hurt for talking. Yorichii nods and goes to another room with his brother. Mitsikatsu sighs as they sit down on his bed, ,,Why?" Yorichii looks down, disappointed with himself but answers, ,,I don't know... I defeated him easily but something inside me, stops me from beheading him. It is as if my body forgot how to kill a demon and how to whield a Katana. Aniki what is wrong with me?" Mitsikatsu blinks a few times before laughing, ,,Little Brother. If I understand, how you feel, correctly. Then you're in love with him." Yorichii looks petrified at his older twin. ,,How?! Just two weeks ago I lost Uta and our child.... How could this have happened?! And why him?", the slightly taller but younger Twin exclaims shocked. In his head a million questions but one think now is opening himself up. He, Yorichii Tsugikuni, strongest Hashira, is in love with not just any Demon, but the Demon King himself. ,,Aniki! What am I suppose to do? This can't be! He is my sworren enemy! I have vowed to kill him even at the cost of my life! How? Why?!", Yorichii asks slowly tears forming. Why was Fate so cruel to him. His first wife cheated on him, his second died from illness and now he likes a monster? Yorichii is not bothered by Muzan being a guy as well but what bothers him, is Muzan being a monstrous Demon. Mitsikatsu stops laughing as he sees the tears and the desperate look in his brothers eyes. He pulls the other one in his arms, ,,I don't know. No one does. But I'll stay with you. I am not ever leaving you alone again. How about this. We are the two strongest Hashira, so it will work. At the next meeting you'll say we have killed him. But in truth we keep him here. Since the crows don't enter we can hide him easily. And because of our strength we can keep him at bay and ensure he doesn't kill people. You can get to know him and maybe one day you two end up together. And if he does try something we can still always kill him. If you want I would do that so you won't have to force yourself ok?" Yorichii looks at his brother questioning how he was so lucky to have a brother like Mitsikatsu. Slowly he nods, ,,Okay. But what if they still find out?" Mitsikatsu sighs heavy, ,,I'll take care of them. If you can be happy with him then I'll move the Ocean to make sure that he won't be taken from you if he treats you well and behaves." Yorichii smiles brightly before diving in for another hug. Meanwhile Muzan is still standing Infront of the door like he was left. He only dared to breath. He now knew who these two were. They were the Tsugikuni Twins. The most feared and strongest Demon Slayers and Samurai's of the modern time. They even could outshine most old legends and tales Samurai, and each on their own mind you. To say Muzan is scarred would be an underestimation, He is to scarred to think. He only dares to breath as he wishes to not suffocate himself. Surely they were discussing on how to torture him. As his mind absently races though all know tourtures, both twins come back. ,,You will stay here. If you follow our rules we'll let you live. Break them once and your dead. Got that?", Mitsikatsu asks. Muzan could only nod. ,,Good. The rules are simple. 1. No Turning people into demons when we're outside. 2. No eating humans. You can from time to time have blood from us. But only that. 3. No being near windows during the day. And lastly no trying to escape. If you do any of that we'll immediately kill you.", he continues. Muzan nods again. Mitsikatsu then steps towards him making the Panik rise again. Muzan closes his eyes in fear and shields his face with his arms not daring to look. The steps stop and others move closer to him. Closer than before. He starts to shake violently in fear as tears form. His breath and heart shortly stop as he feels two strong arms wrap around his torso. ,,We are not going to hurt you if you behave. Ok. We are not as bad as the story's make us seem.", A calm voice sooths him. He indetifies it as Yorichii's tho now filled with care and warmth. Muzan nods and before he can do anything else he falls asleep, slouching into Yorichii's arms. The latter smiles at the sleeping figure before picking him up, ,,Aniki. I'll put him to bed. Then we can cook?" The older twin nods, ,,Yes Yorichii. But please lock the window. The sky looks like a storm may be on it's way. He could get hurt if the window opens an draws the windows open, or a Crow may see him." Yorichii nods and brings Muzan to his own bedroom. He puts the sleeping demon down on his Futon before taking a closer look. Muzan does look very calm for once since they met earlier and quiet handsome at that. Yorichii carefully carres the demons cheek before locking the window and drawing the curtains shut. While cooking both twins sing their favorite song. Their uncle sang it to them when they were little.
