Sinner (Modern KNY!)

"Oyakata-Sama? You requested us?" The heterochromic man asks.
"I have quite a dilemma, I was hoping the strongest of my children could ease this burden."
"What is it, Sir?" A man covered in scars speaks.
"There is a special mission... I hope you can accept this. (Name)?" Kagaya states, a wave of his hand opening a door.

The most beautiful woman any of the Hashira had seen walked out of it. Her silky, (Hair Color) hair framed her delicate features, combined with her porcelain skin, they could only find only one thing that's wrong. Her captivating (Eye Color) eyes had mere slits for pupils.

"Nii-San..." She whispers and Kagaya looks at his younger sister in concern.
"What is the mission?" A deep, but calm voice of a certain blue-eyed man cut the silence.

"Then what does she need if it isn't sleep or flesh?" The first man spoke again.

"I need to be..." (Name) starts but blushes brightly.
"Oh, fuck me." The scarred man says when he realizes what she meant.
"Surely you have an objection to this Oyakata-Sama?!" The only man who hadn't spoken nearly yelled.

"I believe only the Hashiras can keep her from becoming a monster. That being stated, do any of you wish to decline this mission?" The leader of the Demon Slayer Corps questions and five minds all thought at once.

A mission to have sex?

"No." They all chorus and the curvy woman smiles shyly at them
