Error!Sans AU X Reader (LEMON)

Chapter 1

Great. As soon as I was half way home, it started raining. So cliche. There wasn't even a small amount of people walking along the road. There usually is a pretty big amount of pedestrians. I didn't have my phone with me, so I couldn't check the time. Besides, if I had it, my mom and dad would have tooken it away.
Well, at least I got away from that party. Never again! By the time I finally got home, I was soaked and wet. It was the perfect day to wear my favorite black dress. That stopped at my thigh. But the worst part? My dress was now see through. Yeah. You could see through my dress. A couple of guys my age walked past me like, 5 different times. Every time they would pass me, they slowed and stared instead. One even attempted to grab my breasts, but I smacked his hands away and flipped him off. He snorted and shuffled away, his guy friends all laughing at him yelling "REJECTED!"
I eventually arrived home, and I walked up to our door. I slowly opened it, throwing my purse on the nearest table and walking into our living room. My parents were sitting on our plaid couch, probably discussing my punishment.
My dad was the first to notice I was home because my moms' back was facing me. My dad made a grunt like noise, and my mom quickly turned around, but she looked surprised.
Her 2 seconds of surprise, her face quickly turned to anger. I knew before she even told me what my punishment would be. She would take my phone away again like she always does. I run up to my room and grab my phone, heading back towards my parents who were impatiently waiting on me.
My instinct is to throw my phone towards my mom, which I do. My mom catches it, sitting it down safely on the coffee table. She looks back at me, arms now wrapped around her chest.
My dad was tapping his foot against the hard floor, glaring at me. Oh no. They have something else planned for me.
"Y/N M/N L/N. You are in so much trouble." My dad said angrily.
When he says all three of my name, you know I'm fucked.
I smile weakly, which didn't please my mother.
"We're not taking your phone away this time, well, we kinda are. But we have something else planned for you. We're sending you to a behavioral center."
What?! They can't! I've got friends here! "Mom, wait. You've gotta be kiddin' me, right?" I said in an almost angered tone. Who died and made her Queen Bitch?
"No Y/N. I'm serious. You have caused us too much problems that we just handle. Your father has already called the center in Chicago. You need to pack your bags,your Aunt A/N is coming in 3 hours." My mom looked like she was gonna regret something, or she didn't want to send me off to some center for rebels. I mean, I would!
I was stunned. I stifled some tears, which was lucky for me because I didn't want to look like I was going to miss my parents. Which I probably would.
"Fine. Get rid of me, see if I care." I wasn't going. Instead, I was just going to pack so I could runaway. It's not like that stupid center was going to come hunt me down like a wolf hunting a blind baby squirrel.
I heard my dad sigh. "Now, Y/N. You know very well that we don't want to get rid of you. You just need to stop sneaking off to parties and doing other dangerous stuff that would harm you."
But I wasn't listening. I kept walking up the stairs, stomping to add to the point, you know, to prove how pissed I was. I opened my door and stepped inside and took a quick look around. It was all the way I left it. I slammed my door shut and ran to my bed. So soft... I was gonna miss my soft, soft bed. I signed a looked over on my wall, where my Justin Bieber poster was hanging. It was an old poster, really. Made in 2007. Did I mention it was the year 2016? Well, when we first got this house, I noticed a small hole in the wall so I snuck into our garage and took a crowbar. There happened to be a whole new room my room hidden in my wall! I hid small stuff there, like diaries and cool nick-nacks, and before my mom and dad noticed, I covered the hole with my JB poster. Cool, right?
I got up to see some of my things. I put an old picture of Brands G/N. The one that died 8 years ago. I slowly pulled my poster off and gently tossed it on my bed. But when I looked back at the hole, it was open.
Then that was when I realized something. Someone had been in there. But who?
I quickly opened it, and gasped at the sight. There was nothing in there!
"But...?" I started hyperventilating. Yeah, I get nervous easily.
There was a small chuckle that came from my bed, and it sounded male. I turned around, almost tipping over and falling.
"Don't worry, kiddo. I was just reading your diaries. I can't believe you did that in 3rd Grade."

Oh boi. If you see any typos, please feel free to tell me. I'm also taking new story ideas because I got none. I hope you enjoyed this chapter! And I've decided on a name: Little Sinners. I'm calling you all Little Sinners. ~Author-Chan (PS art by Goldy DeeBladeDee on Tumblr. Check her awesome art!)
