A/N: Hey guys! So I'm doing it; writing a Gravity Falls fanfiction...this should be FUN!

Why I'm writing this: my younger sister got me into this fandom, and for her sake, I've been searching the Internet to find her some sweet, cute, fluffy fanfictions. What I find: Pinecest.

Now, most ships I don't mind. Sure, I may not like them, but I often think that you should be able to like what you want to like. But Pinecest...IS WRONG. They are TWIN SIBLINGS, based off of the animator and his twin sister! It's revolting, and it should STOP!

So, I'm distributing to those who want sweet, cute Dipper and Mabel action WITHOUT it going too far. So here you go. Enjoy!

A flash of light filled the room from the window, soon following by a loud explosion of noise. Rain hit hard against the window, causing five-year old Mabel to soon wake up from her calm dreams, forcing her into the scary and dark reality.

She stared at the window for only a second, as another flash of lightning came from the sky. She gasped and hid under her soft, pink blanket, trembling.

Nothing scared Mabel in the world, not when Dipper was always beside her. But lightning was the only exception. Every time it illuminated the room, every time a loud burst of noise followed…it made her tremble in utter fear.

But she wasn't going to tell anyone that. She was a bigger girl now, turning five about a week ago. She wasn't a baby anymore. She wasn't going to be scared. She was tougher than this.

Confidently, Mabel threw the bedcovers off of her head and lied back down, closing her eyes and awaiting sleep to overtake her once more. But it didn't matter how hard she tried; no matter how hard she attempted to ignore her fears and stay strong, she began to shake once again at the sound of another lightning bolt.

Mabel felt tears welling in her eyes as her breaths became quicker. Baby or not, she couldn't take it anymore. She needed someone right then and there, and luckily that very person was in the room.

She slowly got out of bed, clasping her teddy bear in her hands as she walked quickly to the other side of the room, and with a small sigh, Mabel shook her twin brother awake.

She heard Dipper groan from being pulled out of sleep, and he sat up, rubbing his eyes as they adjusted to the dark to see Mabel in front of him.

"Mabel…what's wrong?" Dipper asked tiredly, turning on the bedside lamp, and frowned as he saw tears still dampening her eyes.

"I c-can't sleep…" She trembled, shaking harder as she heard another crack of lightning from out the window.

"Do you wanna sleep with me?" Dipper asked, not affected by the thunder whatsoever, and Mabel nodded quickly.

Dipper lifted up his blue bedsheets to let Mabel, who was shaking less, crawl underneath. She curled up quickly under the blanket, squeezing the stuffed animal to her chest tightly as thunder cracked loudly from the outdoors.

"It's okay, Mabel…it won't hurt you…" Dipper said sadly and slowly, hating seeing her in such a low state.

"I know…" Mabel mumbled into the stuffed bear's head, feeling slightly foolish for being scared at nothing. But in a moment she felt an arm wrap around her.

"It's alright, though. I used to be scared of the dark, you know…"

"Really?" Mabel asked, smiling slightly. She had never heard Dipper admit this.

"Uh-huh…"

"How are you not afraid anymore?"

"Well…if a monster DID come out to hurt me, we would fight it together, and that doesn't seem too bad, so I'm not scared anymore."

"...so if something w-was going to attack me…you'd help me defeat it, right…?"

"Of course!" Mabel smiled slightly, realizing she wasn't shaking any longer.

"Thanks, Dipper…"

"You're welcome." The two sat in a comfortable silence once again, before Mabel finally drifted off to sleep with her head on Dipper's shoulder.

"I'll be okay." She whispered to herself softly before falling into a deep sleep completely.
