—————————————————————————

It was like any other day. Well, not really.. Ever since tanjiro became a demon the entire world has just been at its worst point. The hashiras were wiped out and normal demons were rising in numbers rapidly. This didn't bother the Demon king but it did bother you.

You never asked to be a demon, it was by force and you didn't have a choice since if you declined you wouldn't even have time to think before you were killed. Now here you are, a servant and maid for the king and you never agreed to it so life was almost devastating..

But everything changed that one day..

(Your POV)

Here I am, kneeling beside the demon king as he slaughtered endless demons for entertainment since turning them into a demon wasn't enough for him..

As I was floating around in thoughts, A felt a harsh shove as I would've fallen face first into the ground if my hands weren't on the ground before I fell. I looked up and saw the demon king it as most would say, Tanjiro. He glared at me with narrowed eyes and a scowl on his face.

"What we're you thinking about, Servant..?" He asked, Venom in his voice and I immediately bowed down to him with my palms against the ground and my head slightly touching the floor.

"I-I was just lost in thought..I'll make sure I doesn't happen again.." I said shamefully and kept my head against the ground before I heard a 'Tsk' and he started to walk away.

"Get the mess cleaned up, And I have to speak with  you later today." Was the last the he said before he disappeared and a few other servants came out of nowhere and began to rapidly clean up the blood from the ground.

"What was that about.." I mumbled and grabbed a Mop and a bucket of soapy water before mopping the floor and rubbing of stains that the mop couldn't reach.

It took around half an hour for us to complete and I was just about to go towards my usual spot before I heard a familiar voice right behind me.

"(Name)..I need to speak with you, now." He said and soon he pulled me into a room before locking the door and pinned me against the bed, I still couldn't process on what was going on until he started to speak again.

"I'll explain everything later but please let me do this before I tell you." He asked and looked down at my vulnerable state with those dark eyes and I slowly nodded before I heard a chuckle and the feeling of my clothes disintegrating.

"I'll be slow.." He says before twisting a nipple and softly sucking on the other one earning a moan from my mouth.

"M-my lord what are you?! ngh..~"

He didn't respond and continued to suck as he removed his hand from my nipples and used to it pin both of my wrist above my head and placed his body weight against my legs so that I couldn't thrash around. He slowly grinned himself against your lower region as he made you feel how hard his crotch is.

I moaned and slightly gasped as I felt shackles on both my wrist and ankles before he got off and slowly began to undress himself, shirt first and then he worked his way down to his pants before untying them and removed his undergarments as well before grabbing your hips and aligning himself against your asshole.

"This is gonna hurt but try not to scream."

"What do you mean-" I stopped and let out a scream as I felt my hole being stretched open every time he pumped into my ass and pulled out before ramming into my hole roughly which earned a few grunts from him.

"Y-your ass is fucking tight.." he grunted and began to pump himself in wildly as he held your hips in place and lifted up your leg and placed it in his shoulder before ramming deeper into you.

"My lord I'm gonna..!" You we're then cut off my a loud moan as you felt yourself orgasm and then you felt his shaft twitching inside you.

He only hmed and began to quicken the pace as you moaned as you felt sensitive from your earlier orgasm before you felt thick ropes of cum shoot into your ass with some spilling out.

He then unlocked the shackles and you fell onto his chest, panting heavily as you rested layed down against him. He soon then wrapped his arms around your waist and pulled the covers over the both of you, caressing your cheek with one of his thumbs.

"I live you (Name)..I always have-" He stopped and slightly chuckled as he saw you already fast asleep and placed his chin ontop of your head.

"Goodnight (Name).."
