CHAPTER ONE - IN DENIAL

Dipper's POV

Wow, time flew so fast, and now Mabel and I haven't spent summer in Gravity Falls for a long time now just because we had to attend high school. Speaking of high school, ordinary things are gonna look back at me again. Ugh. I can't wait to spend time with Great Uncle Stan and Ford.

"Hey, Dipper!"

Fortunately, my twin sister Mabel shook me out of my misery.

"What is it, Mabel?"

"Can't you believe it?? We're finally Seniors! Oh! I really hope my date to the prom would be a vampire--"

"Mabel," I absentmindedly grunted, "we're no longer in Gravity Falls. There's a .01 chance you'd get a vampire for a date."

"Oh come on, you're still not over with that, are you? It has been 3 years after we moved out. I'm pretty sure our Gruncles are doing great--" she bumped me with her arm.

"It's not that. It's just that I miss them and our adventures and honestly, atleast you had a greater high school experience than I ever had. High school is nothing compared to Gravity Falls." I said as I picture my old blue cap.

"Don't worry bro-bro, I'll always be here."

"I know you will be, sis." I smiled assuringly at her.

I forgot to mention that even if Mabel and I grew up physically and mentally, our parents still make us stay in one bedroom. Not that it bothers me, but it just gets weird sometimes. Anyway, she's still my sister and she's equally my responsibility. Besides, it never bothered us before, so why would it bother us now.

And I was so goddamn wrong.

Later on, there she was. Mabel coming out from the bathroom, soaking wet even if she already has a towel covering her up. I actually stared at her for, like, 4 seconds until she finally looked at my direction.

"Sup, bro?"

"O-oh, it's nothing." I nervously stuttered and looked at somewhere else. Why the hell am I looking at a sock??

"Oh, that reminds me. Jenny chatted me about the official invitation giving for our prom night! Guess who's my date?" she exclaimed as she brushes her hair.

I chuckled, "So you found a vampire in a short notice?"

"No, well I wished, it's Anderson."

"WHATA?!"

"Yyyyeaaahh" she flustered her eyes awkwardly, "I knew this would be your reaction, Dipper."

"THE ANDERSON?? You know I hated that guy, Mabel. And I'm gonna see you dance with him--not to mention, date him!" I grabbed her shoulders and reasoned out.

I hated Anderson so much that I couldn't think of any good reason to allow Mabel hang out with that guy. Anderson Leavy is my arch nemesis at school because he's such a dim witted person who likes to brag in Facebook all the time; he even claimed my project work as his own!!

"I can't believe this, Mabel. I would choose the gnomes over that guy. Seriously."

"Are you freaking serious? Those gnomes aren't o b v i o u s l y my type. If I do, then I could have accepted their proposal. Yep, magical creatures can't resist this Mabel." she smiles.

"Well.. Uhh. Do you even like Anderson?" I looked at her directly in the eye and held her shoulders firmly.

"I--well," she snorted, "even if I don't, who would take me to the prom anyway?"

I would. I grinned and loosened my grip.

"You're the quirkiest person I know, Mabel. Who wouldn't like to ask you out?" I walked back to my bed.

"Thanks, Dipper." she headed to the divider and wore her clothes on--

--which left me staring at her. Her shadow displayed her slender figure while she's pulling off her towel and wearing her bra.

SNAP!!

"Aww, damn it!" she cried.

"What snapped?" I asked out of curiosity.

"The hook of my bra broke. Uhhhh, Dipper? Could you..uhh, get me a new one from my drawer?"

I was awfully blushing and felt my face grew hot, but my sister needs my help so I guess I have to do what a brother have to do.

So I went to her drawers and browsed through which drawer contains underwears... Which makes it weird--er, but I immediately found stacks of them.

As I was about to get the first one on the pile, I felt my hand shake with nervousness. AM I REALLY DOING THIS? DEEP BREATHS, DIPPER. THIS IS FOR MABEL, YOUR OWN TWIN SISTER.

"Bro, what's taking so long?" I heard her voice nearby, I guess I was staring at the bra for too long.

"Dipper, they're only bras. You don't have to look like you're gonna get eaten by them." she snorted and grabbed one from the drawer.

"I-I'm r--" I turned my head and I saw her wearing her loose shirt and skirt.

"Mabel? Are you wearing anything under--" I trailed off as I shake off my confusion and curiosity.

"No, dummy. Why would I ask you to get me a new one if I had one all along?" she says as she headed back to the divider.

"Right. Hehe.." I scratched my head with pure embarrassment. What's going on with you, Dipper??? I looked back at the opened drawer and felt my face grow hot again. Okay, I just can't let the awkwardness run over me. I JUST CAN'T.

"Soooo, where are you headed? It's such a nice day, isn't it? Wanna go somewhere? You know, as twins, o-or as siblings, get it? Do you...?" I literally shouldn't have said that. My plan of not letting the awkwardness run over me backfired.

"OH MY GOSH YOU'RE TOTALLY RIGHT, DIPPER! We never get to do fun things together ever since high school came to our lives--well, except Halloween and other holiday stuff." she stepped away from the divider wearing a tank top and then she steps towards her closet to probably pick the sweater of the day.

I watched her pick a sweater from her collection; I've seen her do this alot of times but why do I feel this now? Why now? Just then, I felt tiny bits of sweat running down my forehead.

"So, where do you wanna go? I've been planning to go to that new arcade downtown! They have sparkling hoodies that I REAAALLY have to win for." she beamed at me.

"Yeah, sure. Wherever you like, Mabel. Would you excuse me for a second?" I quickly went to my own closet and wiped my sweat away and calmed myself down. THIS IS NOT HAPPENING, DIPPER. SHE'S YOUR SISTER!

-THUMP-

"GOTCHA, DIPPER! Hahaha!" MABEL IS HUGGING ME. SHE'S FREAKING HUGGING ME. Whatamigonnadothisisawkward!! I felt her breast compressed at my back and her damned soft skinned arms wrapped around my waist, "S-stop that, Mabel. We aren't kids anymore! And where's your sweater?? I thought you were wearing one??" Crap. My voice cracked.

"Oh, come on, Dipper! It's only hugging! And I need you to pick me one!" she grabbed my hand and lead me to her closet.

She switched on the lights and grabbed two selected sweaters. One apple green and one orange. She held them up at both sides of her body which displayed her cleavage perfectly in the middle.

I...honestly caught myself looking at her breast for a second until my eyes diverted to Mabel's eyes instead.

"You usually pick my sweaters and since we're going out, I'd like to give you the honor of picking my sweater for the daaaay!" she giggled.

"You look beautiful in any clothes you wear--I-I mean, I would prefer the apple green sweater." I replied.

She thanked me and we headed towards the arcade afterwards.
