Best Friend's Sibling AU

"Oh my gosh! Jughead get out!" JB screamed at her older brother as he stood at the door chuckling at his sisters reaction to him finding her and Betty in full sleep over mode. High ponytails, facial masks and pjs.

There was about 15 months between them which meant most of the time they got along fine. But he did love to tease her just a little bit. Betty hid her face behind a pillow while JB stalked to the door and slammed it in his face while his laughing could still be heard through the door. Betty meanwhile did her best to hide behind a pillow. They had been jumping on the bed singing into their hairbrushes masquerading as microphones when his laugh from the doorway had broken their little bubble.

"Argh, older brothers are the worst!" JB exclaimed as she flopped backwards on the bed. "Wish I had an older sister like you."

"Please having an older sister is not that great. All mum ever says is 'why can't you be more like Polly', 'Look at how well Polly is doing'" Betty emanated her mother perfectly even with her face covered in the pink clay substance, which had JB in a fit of giggles.

"Okay," she struggled to regain her breath as Betty continued to waggle her finger in the way her mum was so fond of doing.

"Okay, stop. Maybe it isn't that bad." Betty shot her a look before grabbing a handful of popcorn, she didn't have the watchful eye of her mum here to tell her to stop, to watch her figure. At JB's she could be free.

And, well, Jughead was there.

Betty had had a crush on her best friend's older brother since she knew what crushes were. While the other girls in her class were writing Archie's name on the front of their notebooks surrounded by love hearts, Betty only had eyes for his beanie wearing best friend. She had found herself wondering what his hair looked like under that beanie. Every time she visited JB she hoped she would catch a peak. Have something new to fuel her fantasies and day dreams.

JB lifted up the bowl that had started full of popcorn and now only contained a few unpopped kernels. "Looks like we are out."

"I'll go pop some more." Betty said jumping up, not that she had any reason to be in such a hurry to be in the common areas of the house. That she might 'bump' into someone. Or catch a glimpse.

"You might want to go wash that, off first though." JB said indicating to the clay mask which Betty could feel tight on her skin.

"Oh yeah." Betty agreed as she grabbed the bowl before heading towards the bedroom door. "Thanks."

After washing off the mask she made her way to the kitchen and put another packet of popcorn in the microwave. As she waited for the popcorn to finish she jumped up on the kitchen bench swinging her legs. Her mum would never had let her sit on the counter.

"Refilling on snacks?" Jughead poked his head around the corner of the entryway to the kitchen making Betty jump at the sound of his voice.

"Juggie." She pressed her hand to her chest in an attempt to calm herself from the sudden shock. "You scared me."

"Sorry Betts." He moved closer to her, as he leaned up against the counter that she was up against.

Betty tried not to let his closeness affect her the way it did. She had told herself on many occasions that she shouldn't be feeling this way about her best friend's brother. That it was a betrayal of sorts. But she couldn't help the way her cheeks flushed and her pulse sped up as he moved closer. The brush of his hand against hers made her body tense and her eyes to flash up at him, whether it was a deliberate touch against her skin. Whether it could all just be in her imagination.

"The popcorns ready." The sound of his voice brought her back to the room and the beeps that the microwave was emitting. She pulled the packet from the microwave and quickly tipped them into the bowl. She gave him a quick smile, as she moved past him back to the relative safety of JB's room.

"Wait a second, Betts." Betty stopped in her tracks. She turned to see that Jughead was now standing in front of her not even a foot away. Her heart was thudding in her chest as he reached towards her and Betty forgot how to breathe. His hand dug into the bowl, pulling out a handful of the freshly popped corn and shoveling some into his mouth. He gave her a wink and a mumbled a 'Thanks' before he brushed past her leaving her alone in the kitchen.

Betty stood stunned before she shook her head at her foolishness before she started to move again trying to forget about her school girl crush a few rooms away, who may just have been thinking the same things as her.
