Yandere (probably monster) girls x fem! Reader

[Demon]Jester x reader (Lime)

(I didn't feel the need to specifically say "fem! x fem!" Because of the title. Yes, this is Jevil & Rascal inspired. Mostly Jevil-)
⚠️Biting, Gore⚠️

You were a princess. You had a little sister who would always cause trouble if she didn't get attention, so your father decided to hire a fool. You didn't mind as long as it stopped that little demon breaking & ruining your things. She seemed happy & was constantly smiling, which made you happy. Hey, she may be a hell-spawn, but she's still your sister! Though, you noticed the jester would always try to get your attention. It started out with just bumping into each other in the castle or garden, but it was starting to seem a little too convenient, I mean, it happened every time you went somewhere! They also would try to talk to you for hours, & would try & touch you! Not in the weird way, but they would try to hold your hand, hug you, grab your arm, along with asking you questions & talking about you as if you were dating them, they would say how beautiful & smart you were. Unfortunately, you had no idea that what was going to happen. What you would find.
As you were heading to your sisters room to deliver her cookies you baked, when you noticed it was rather quiet. No footsteps, talking, no giggling from your sister. The entire castle was just...silent. You opened the door & dropped the tray of cookies after trying to back away from the sight. Your sister looked shriveled, just a bag of flesh & bones! Your father & mother were cut up, their blood & internal organs were spread out everywhere! Your sisters ones baby pink walls were soaked in blood, a small, glowing circle in the middle of the room. & where was the jester? Eating your mothers torso like an starving animal. They look up at you, her eyes now pitch black, with the exception of the red diamonds, which turned to pink hearts the moment she looked at you. She got up, & you could see her more clearly now then when she was huddled in a corner.
Her skin, instead of being pale, almost white, was now a dark, almost black, red. Her teeth were like a sharks & she had horns that sprouted from her head & curved upwards, yet she was still, though covered in blood, still in the same jester outfit she wore to entertain. She was...horrifying!
"Darling!"
Her voice was deep, like a mans, but had another one, a more high pitched one that followed only a little behind the first voice.
"You came! You...this wasn't supposed to happen! You supposed to fall asleep! Then I would take you away, forever! Hahaha!!"
You were horrified! What was this creature planning to do with you?! Eat you?!
"I'm sorry! I couldn't take it anymore—
Being around warm flesh,  fresh blood! It was driving me INSANE! HAHAHA!
I was trying so hard for you, my love, but they were just too easy & smelled too good!"
She was stepping closer to you, & you felt yourself falling on cold, hard floor, on your stomach. She was pinning you, her tail waving slowly in the air. Her mouth was too close to your neck.
"You smell good too..."
You froze.
"Do you have any idea what I've been holding back? I've been trying to restrain myself  from taking you..."
She nuzzles her face into the crook of your neck.
"Just a taste...please..."
She didn't wait for an answer, she bit down onto your neck, & you screamed! It hurt so much! She began licking off the blood.
"So sweet..."
You tried pushing her off, but she was inhumanly strong.
"I'm not going to eat you...at least...not the way I eat all the other humans~"

(Sorry! I know this probably sucks, I'm writing this at 2:03AM, & I'm watching the Sonic fandubs-)
