You brought your family to the butterfly mansion, and they were being taken care of. Tanjiro was nice enough to explain to you what they all did in detail, while Inosuke just said he killed things. You put Inosuke's hair up, which both boys were surprised he let you. You smiled as you were helping clean up Inosuke and patching him up as well as the other two boys. Muichiro Tokito was watching from a distance and didn't see why you were so happy after your wedding day was ruined. You found out demons existed, and you got hurt. But when Inosuke put on the clothes you made him, he was shocked and horrified seeing he was smiling at you. It was even a calm smile, which wasn't like him.

You fell asleep while you two were sitting together, and Inosuke let you lay they for a bit so he could bandage your hands. You said you were fine multiple times, but he knew you weren't used to punching people that hard, so you were going to be hurting tomorrow. He let you rest on his shoulder and even fell asleep with you, but as soon as he felt you moving, he was wide awake. He saw Tanjiro trying to carefully separate you two so you would be more comfortable.

"Sorry, Inosuke, I just wanted you two to be more -" Tanjiro said, and Inosuke wrapped his arm around you.

"Mine," he said sternly, making Tanjiro smile.

"I'm not taking her from you. I was going to lay her down," Tanjiro said, but with Inosuke's look of determination to keep you with him, he backed off.

Inosuke picked you up, carefully then moved you into a different spot and laid you down next to him. He fell asleep again, holding you close to him, and in the morning, he left you early to get you some flowers. When you woke up, you got up and stretched out a bit before realizing you weren't home asleep in your bed.

You got out and noticed that the demon slayers were there and getting regular checkups and some food from their long journeys. You bumped into one by accident, and the man turned around and smiled at you.

"Hello! You must be the new doctor they wanted on board!" The man smiled as you looked around, still slightly confused.

"Demons are real still, right? Sorry, I had a rough night," you said.

"Yes! From what I heard, you met your first one last night. Congratulations!" He said cheerfully.

"Um, thank you. You must be Kyojuro Rengoku Tanjiro, who talked about you a lot and tried to get me introduced to everyone on the way over here," you said.

"Amazing! Did he tell you about why wife?" He asked.

"No, not that I can think of," you said

"We met on the Mugen train, and that's why I am still alive. If it wasn't for her, I would be dead," he said.

"But you're a demon slayer," you said.

"Yes!" He said.

"So she's like Tanjiros sister then?" You asked.

"Yes, but she can speak and use demon slayer forms as well as demon forms. She saved my life, so I fell in love with her and got her pregnant!" He said, making you silent.

You couldn't tell if he was nervous or liked being blunt and oversharing things.

"Kyojuro Rengoku! You can't keep going around and telling people you got me pregnant!" A beautiful woman said as he smiled.

"Sorry, he's very outgoing, and I think he is also a bit nervous that he's going to be a dad here soon. Your dad still wants nothing to do with me, does he?" She asked as he sighed.

"He will come around," he said as her water broke where she stood.

"Well, I guess it's time," she said as his face turned as white as a sheet.

"Yeah," he said as he helped her along to one of the girls.

"Demon slayers are weird," you said to yourself as Inosuke came down from the ceiling, making people scream, but you.

"Hi!" You said as you hugged him, and he gave you some flowers he picked.

"Aww, thank you!" You said with a smile as you took them.

"How is your hand?" Inosuke asked as you realized he bandaged it up for you.

There was some dry blood on the bandages, so your hand must have bled some without you realizing it.

"Good, I never even felt it hurting," you said as he touched it a bit only for you to flinch.

"Sorry," he said.

"It's okay, as long as I don't touch it. I guess it should be fine," you said as he smiled a bit.

He seemed a bit nervous around you, and you didn't know why, but you had an idea why.

"Y/n!" Tanjiro said as he went over to you.

"Yes?" You asked as he looked at you terrified.

"Mr. Rengoku passed out in the delivery room!" Tanjiro said as you looked at him shocked.

"Don't ask me what to do! Just drag him out!" You said.

"I can't! The girls kicked me out since his wife was giving birth, yet they also told me to get him out..." he said as you grabbed some smelling salt.

"No, don't get him out. He helped put the baby there so he could see how babies were born. This will work. Break it under his nose," you said as he sighed.

"Okay.... thank you," he said.

Your parents were watching you, and you knew why. Inosuke had a thing for you, but so did you. You thought you lost your chance with him after he left. Your parents told you he liked you and to your horror, so did you. You were going to follow him but decided against it because you didn't want to be a creep also your mother said if it was meant to be he would be back soon so you took this as a sign.

"Can we talk outside?" He asked as you looked at the flowers and how he bandaged your hand for you correctly after showing him a thousand times.

"No, because I have a surprise for you too," you said as you grabbed his face and kissed him.

He started kissing you back, and to your shock, you ended up on top of him and fully made out.

"Ahhhhh no! How!" Zenitsu yelled terrified as people were staring horrified.

Inosuke was known for his animal-like behavior and being loud, but you didn't mind it at all. You enjoyed his energy and felt at ease with him oddly enough. You loved him, and nothing was going to change how you felt about him.

"Inosuke, you have to get off of me please," you begged as he sighed, then got up.

"What do you mean how?! I'm awesome, that's how!" He said as you had to hold him back from fighting Zenitsu.

"He's just shocked. There's no need for you to be hostile," you said as you were holding his shoulder.

"He should be shocked. I have the most beautiful girl around," he said as he smiled at you.

After some time, you were in your room that the girls gave you until your house could be rebuilt. Your family decided to go back to the village due to the increase in sick people there. Inosuke had snuck into your room, which you figured he would eventually. You were getting ready for bed and had to change your clothes. you were changing your clothes in front of Inosuke, who was on the ceiling. You saw him out of the corner of your eye and in the mirror, but you didn't mind it. He was looking away after his face turned bright red.

"Inosuke, why so shy?" You asked as he nearly fell off the roof after realizing you saw him.

"I'm not shy!" He said as he hopped off the roof.

"Yeah, you are. Your face is all red," you smiled as you cupped his face with your hands and kissed him.

He felt so warm, and he wanted to be on top of you again. He put you on the ground and started kissing you harder. He felt his body wanted something, but he wasn't sure what. All he wanted was to kiss you and to touch you.

"Someone needs some attention," you smiled as he turned red.

"No," he paused as you untied his rob.

"Why did you do that for?" He asked as you touched his chest and slid your hands down to his waist, making his body extremely warm.

He did the same thing to you, slowly untiring your rob, opening it up to see you were not wearing anything underneath it. He was speechless and didn't know what to do with himself. He took off his rob taking the hint, and you pulled him closer to you and started fully making out with him again. You took off your robe and touched his back, trying to get him closer to you. You wrapped your legs around his waist and were waiting for him to put himself in you, but he wasn't doing it. He just wanted to be close and kiss you, and it seemed like his nerves were getting the better of him.

"Do you want to?" You asked as he seemed unsure.

"I don't want to get you pregnant just yet," he said as he was thinking about doing it anyway.

"Just pull out when you feel like you are going to explode," you said as he smiled.

"I always feel like that when I'm around you," he said as you smiled.

He carefully put himself in you and kissed you roughly. He never felt so good in his life and wanted to be with you forever. Every thrust was uneven due to him being new at this, but you didn't mind. This was perfect for you, especially since you were with him. You dug your nails into his back, wanting him to be closer to you still.

He started bucking his hips harder into you, and then he pulled out only to flip you over and started to fuck you almost like an animal. You were trying to conceal your moans, but it was harder than you thought it was going to be, and in the end, you were a moaning mess. Finally, he pulled out and came. His breathing was labored, and so was yours, making you smile at him.

"Sorry," he said in between breaths.

"Don't be, it was perfect," you said as you lay down next to him.

You never thought you would give yourself to a guy you took care of, but at the same time, you were happy they found each other even though the circumstances weren't the greatest he still wanted what was best for you, unlike the men that tried to kill you.
