Male Reader x Demon Slayer Harem

Demon Queen and King

You woke up to hear screaming as you stretched, dressed up, got ready, and went outside to see the Hashira's staying as the 3 girls left with a wooden crate. You were confused but just went back to sleep. You woke up mid-day and went out just to kill demons. After a few hours, you went to check on all the girls who were tired from training.

Zenko - Can you sleep with us, please?

(Y/N) - If you want me too, I guess.

Later that night everyone was in a sleeping bag next to each other and you were on the end next to Zenko. Then you saw a wooden crate with a girl coming out of it who saw you look at her in shock.

(Y/N) - You're the demon...? You look... pretty.

She blushed and went closer to you and sat on you as you lay down. She blushed heavily as you got hard and you did the same. She then took the bamboo muzzle and threw it to the side near her crate, she crawled closer to you and kissed you until you did the same. She curled up next to you and fell asleep until during the day when she and you woke up first and she went back into her crate picking up her muzzle. You then looked at her as the lid closed and your eyes widened as you just had an idea. Zenko woke up though and when you sat up she crawled a little closer and sat on your lap and your eyes went to normal as you looked at her and smiled. 

Zenko - Good morning King~

She grinded your lap and you picked her up then put her next to you until one of the Estate girls woke up the whole gang and told them to train. You still sat there watching them leave but Sumiko stayed and walked up to you.

Sumiko - I don't want to say this but I can't control my feelings and... Please don't tell Zenko she will kill me.

(Y/N) - What is it?

Sumiko - I... I really like you!

She then scurried away leaving you there but you went to Kagaya kneeling in front of him.

(Y/N) - Kagaya... Only demon guys did not suffer from the disease... would you believe I'm a demon?

Kagaya sat there before thinking.

Kagaya - That actually might be a good explanation...

You always were sensitive to the sun, getting burned easily and entering a place with a lot of Wisteria trees made you somewhat sick. After talking to Kagaya you took out a family book and noticed your grandpa with sharp nails and pale skin in a photo, Maybe you were a demon. But that wouldn't explain why Kagaya is still alive.
