The Demon Child (CreepyPasta X Reader)

First Happy Birthday

Slender's POV (The night before)

I wanted to find out when (y/n)'s birthday was so when it came we could celebrate. "BEN, I need you to do something for me."

"What is it?" pausing his game to look up at me.

"I need you to go onto the internet and find out when (y/n)'s birthday is."

"Will do!" he then heads into the TV and I make my way to my room. Once in my white pajama's I sit on my bed and begin to read a book. I then hear my laptop turn on. Seems like he found something. I sit at the desk and start to read her documents. Tomorrow? Her birthday is tomorrow?! How come she didn't tell us? Well, I guess I won't be getting much sleep tonight. I put my suit back on and teleport near a party store, in my human form of course. Once I've gotten the necessary supplies I buy them and Head back to the mansion. Before entering the house I make sure no one is around. Good they must be sleeping. I stuff everything into a closet so no one sees it. I then make my way back to bed and immediately fall asleep.

The Next Day

I get up a little earlier than everyone else so I can figure out a way to get (y/n) out of the house until everything is setup. Trender! He can take her shopping or whatever. I teleport inside his room so I don't wake anyone up b knocking on hi door. I see that he's already up and working on what looks to be a shirt.

"Trender I need you to take (y/n) somewhere, today's her birthday."

"Of course! I'll take her shopping! Get her some birthday outfits!"

"Good but don't tell the others yet. We don't want the others ruining the surprise."

"Got it. Well i'll be on my way." he teleports away probably to (y/n)'s room and I teleport downstairs to get breakfast ready.

Time skip 10 minutes

By this point everyone is doing there own thing. BEN playing his game, Jeff and Jane arguing like usual, E.J and L.J sitting on the couch watching Jeff and Jane, Masky and Hoodie are sitting in the kitchen talking about whatever, everyone else is no where to be seen. *Running footsteps* That must be Trender and (y/n).

"Hey where you two going?" I still haven't told them about the surprise party.

"We're going SHOPPING!" she must be excited to say it like that. Once I've confirmed that they are gone I tell everyone.

"Listen up everyone!" everyone stops what they're doing and looks me. "Today is (y/n)'s birthday. We're going to throw a surprise party for her. And we must make this the best birthday she's ever had. Laughing Jack you're in charge of food. BEN and Eyeless Jack, you two will be planning the events. Jane you'll be in charge of outfits. Masky, Hoodie, Toby, and Splendor, you four will setup the decorations. There's supplies in the closet over there. Now get going"

"Yes sir!" everyone says at the same time.

"What about me?" Jeff walks towards towards me and stops when he's in front of me.

"Keep an eye on Offender. And don't piss her off." he groans and then walks away. And I will bake the cake.

Time Pass 3 hours (It's now 1pm)

"Hey we're on our way home. Make sure you're ready." I hear Trender say telepathically.

"Everyone hide they're almost here!" I shout and everyone immediately hides while I turn off the lights making it pitch black. "Quiet," I tell everyone telepathically.

"Why's is so dark?" I hear her say. She then turns on the lights and we jump out.

"SURPRISE!!!" we all jump out .
