JEFF THE KILLER X READER

You hear a thud in your room and feel cold. Your blanket had fallen to the floor during the time you were asleep. Steps in your room can be heard so you open your eyes.
There was this kid with white skin, black eyelids and a big demonic smile carved onto his both cheeks. His lips were blood red and his hair black as the night. You turn terrified as you see the knife in his hand. What else would you expect from yourself? You're still only 9!
Before you started crying some tears ran down your cheeks. He placed his finger onto your lips and leaned closer, cooing into your ear."Hush little girl, don't you cry. Go to sleep." he said and it made you shiver, letting out a scream. Your dad ran into your room with a big gun and before you noticed it, the boy was gone. Your dad closed the window and puts you back to bed giving you a good night kiss.
He left your room and you feel something soft under your pillow. A handkerchief. You take it and examine it closer. There's text written in blood:
This paper. Don't lose it. Always sleep with this under your pillow until we meet again. 'Til then: Go to sleep.
-Jeff
You put the handkerchief back under your pillow being afraid of what'll happen if you lose it and go to sleep as told, sleeping the next night restlessly.

Seven years passed since that night.. You're going through a good education your parents got you. You still sleep that handkerchief under your pillow. But something changed inside you through those years. You wield several knives under your clothes for self defense as you say, but basically just because you want to. By night you lurk into your classmates' rooms and give a little stab to their hands to gather blood. One wall of your room is full of posters, but they only hide your beautiful creation you've painted with the blood. Insane quotes, splattered blood, knife marks. You paint screaming human faces and throw your knives at them. Your steps in the corridor sound haunting. When you walk you look down and seem grimdark and scary as fuck, but when you reach your so called friends you smile and turn bright.
It's night and tomorrow you'd leave home for vacation. You have blood enough to paint one last picture in candle light onto your wall. You used it to write though and wrote three words in big letters: GO TO SLEEP. You hid the thing with posters and curled up under your blanket without removing any knives and fell asleep.
After school the next day you packed all your extra hidden knives from your room with you hiding them all between your clothes. There is something strange in the air so you feel like you should be quite careful. But phew- finally you get home for a while from the private school you go to. You walk down the stairs with your bag of clothes and your knives of course, stuff the bag into your dad's car and hop in. You're safely on your way to home.

At home the strange is way more in the air.
You badass, knives knives and more knives. You have one between your breasts and backside, two on your wrists, under your arms, on your sides, thighs, upper back and two on each shank of yours. Total 16 of them. Whoa.
You open up the window for a breath and see the sun is setting, then place the handkerchief under your pillow. Your bed is close to the window so you can smell the fresh air in your sleep which you are used to. You still live in the same house and you wonder if it was just a dream from seven years ago.
You lock up your room's door after getting a shower. You still have the stitches on your belly from the car accident you ended up killing your mother in about a year ago just to spare her from pain. The wound hasn't closed fully yet because it's so deep and each time you press it the wound starts leaking blood. You press it and see the blood coming out then swipe some with your finger and lick it off. It tastes so soothing for your panicing restless feeling which you always have at home so that's why you lock up into your room to not hurt anyone which was told to you by the dream of your mother.
Suddenly you fall down on your knees feeling weak and breathing heavily. Not again, you think. You see a black flash and then get up throwing the knife from your desk to the wall of your closet, laughing to yourself.
It's time to go to sleep you realized soon and cleared your throat feeling normal again. You put a tank top and your favorite fluffy pajama pants on then go under the blanket. You feel like you aren't able to sleep but you just lay in the bed, trying to figure out how you can turn off the lights without getting up. Then you just throw a bowie knife from under your bed at the lamp and it breaks. Dark. Finally.

Running. You hear running from outside and wake up. It's coming closer and you feel ready. You get off the bed and open your door, running downstairs and putting your shoes on, then run to the forest hoping the someone gets lost as he's around and taking your knife from between your breasts. You get knocked out though and all you remember of that was the familiar but lower cooing into your ear: "Go to sleep."

Your head aches and you rub the side of your head trying to get up. All your knives seem to be in place, poorly though, like someone had removed them and put them back again. Even the one between your breasts. You managed to get up and you stood up tiredly, fixing all the knives back into their places. Then you stretch and look around. You are in a completely unfamiliar room and take out a knife, shining it with a cloth in stress.
Calm steps from behind like the night seven years ago, just slower and slightly louder. A cook's knife presses against your neck and you hold your breath. "Shut up or I'll make you go to sleep" someone cooed into your ear kind of seductively and you took your knife up, mirroring the picture of the one behind you. It was the same boy. Just older than by then.
"It's you. So you decided to keep your little promise after all? Jeff is your name, right?" He put the knife down from your neck and gave a little grin then sat down on the bed behind you, pulling you to sit on his lap like he had known you from a little kid. "Listen up, little girl, I've been watching you grow up. I respect you." How he said that last sentence made you think if it's just because of his possible interests to rape you.
"However," he continued, "I would love to get to know you better to see if the spell Slenderman gave to me worked. You seem to share a few traits with me.." he said and dug up the knife from your breasts. You blush heavily and teasingly rub your bottom against his lap for a payback then pull the pocket knife from his hoodie's kangaroo pocket.
"Well I see you know the ropes. You got any better than this?" you ask and notice him taking a very dangerous looking bowie knife then pokes your breasts with it repeatedly, making them bounce. It makes your nipples harden and of course, you did not wear bra for the night. He pokes your nipple with the knife's sharp end making you moan a bit and then you slide the knife from your left wrist down to your hand and poking with it at his crotch hard. "I'd like to see you t-try that after I chopped your dick off.." you growl. He stops and chuckles darkly, gives a little light bite to your neck and gently pushes you off his lap, getting up and sharpens his knife.
"Would you like to try something new?" he asks standing on the room's door. You look very curious and make him continue: "I'm off for a killing spree, want to join? I know you paint with blood. You'd get all the paint you need."
Your eyes brightened up wide and a devilish grin spreads onto your face. "Why yes, yes of course" you answered and got up licking your lips. He grabs your hand and leads you out of the room, taking you bridal style onto his strong arms and jumps down from the upstairs with you, putting you down and running out with you.
Soon you reached the city. It was still the same night. He sneaked into a house from the window and you followed, seeing him kill the parents of the house. You went and killed the oldest daughter in the house and then the youngest boy, calling Jeff afterwards. "Let's leave our autographs here" you said to him and giggle taking his hand, dipping it to blood on the floor and write his quote to the wall together. You then left to several other houses doing the same in each house.
When the sun was going to rise in a couple of hours from the moment you returned and you saw the house you spent some fun time in together a bit earlier, gasping. It was a great mansion in the middle of the woods. He holds you by hand as you walk in and he glares at all the other guys inside to shut them up, taking you back to his room. He closed the door behind making sure that no one followed you.
He took his knife, pushed you against the wall and hit the knife right next to your neck, grinning. "I think I am falling in love with you" he said and the cold blank-ish insane looking eyes of his looked deep into your soul through the pair of yours. It turned you silent, making your face almost as red as your blood, but it couldn't had been easy to notice as your face was messed up of the splattered blood, but surprisingly he did and pressed his lips to yours suddenly, you close your eyes and kiss back roughly. All that killing turned you on and as he pressed his body closer to yours you noticed that it might had turned him on too. He moved to your neck, kissed and bit it then sucked on the most sensitive spot there he found, licking it afterwards, sliding your pants off you smoothly. His warm humid breath against your neck that had been wetted by his saliva felt so good you made him take a knife from your thigh and cut your panties off, blushing very heavily. He also accidentally pressed on the stitched wound on your lower belly as he pushed you to the bed, making it bleed. He licked the blood off then kissed you passionately while you pulled his pants down using your toes. He then lowered his boxers and let out his member, rubbing the whole length of it against your temple. You moan and take another knife pressing it lightly to his neck. "If you won't stop teasing me I'll stab you until you're dead" you said stubbornly and see him grin darkly. He moved his hips so that the tip was on the entrance of yours, pressing it against you but not pushing in. You sink the tip of the knife into his neck and feel him pushing roughly into your virgin passage. You moan and take your left arm biting the skin to keep from moaning as it was a little embarrassing for you, but he took your arm then and chomped down on it harshly making you feel weak of the painful pleasure and moaning uncontrollably. Your arm started to bleed and you moaned louder, he thrusted rough and hard into you and you almost fainted of pleasure, moaning out his name. You came and your face is as red as a tomato, he growls lowly but seductively "I didn't finish yet, little girl.." and then puts you twofold slamming into you very harshly, making you scream out in pleasure and your tight passage felt even tighter for him. He went so hard you started to bleed from the inside and came hard into you, squirting some out as all didn't fit in. His mouth drips blood and your heart beats faster than ever. You pant heavily and kiss him wildly after that, having him kiss back.
"Let's go to sleep. The sun is rising" he said and parlously pulled you next to him under the blanket. He held you in his arms and slept like a little baby, except his eyes were only open. You didn't think that a killer like that could be actually so cute. You fell asleep next to him.
You're not sure if he had killed you during the first meeting and all of this was just some afterlife dream, but the pulsing but pleasurable pain down your body he gave to you felt real. You actually didn't care, you just went with the flow.

The end(?)
