Summary: Santana has always had a huge crush on her childhood friend's older sister, Brittany but is too shy to admit it. A trip to the local convenience store somehow changes everything. Brittana AU

A/N: Wrote this based on a prompt I received on tumblr: "Can you write about Brinn (or Britt) taking Santana to a 7-Eleven?"

Personally I really like the idea of AU Finn and Brittany being siblings for some reason and both being kinda weird but only they can understand each other's weirdness. I can't imagine Santana eating gas station food lol she'd be so grossed out but Finntany/Brinn would love it.

I highly appreciate any feedback here or on AO3 at any time if you have any thoughts on the story/characters xoxo

Santana was only six (she wasn't a baby, she'd turn seven in August and that was what she reminded anyone who asked her), riding the new red bike she got for Christmas around the block when she bumped into this weird, tall kid with light brown hair she saw sometimes. He had an old looking green scooter that Santana thought looked pretty lame and was wearing a Power Rangers shirt. He had recently moved into the neighbourhood with his mom - that was all Santana knew.

"Hey, do you want to be friends?" The other six year old asked, wincing when she glared at him.

"No!" Santana shouted and left in a flash before he had a chance to answer her, showing off how fast she was. Santana thought Finn was annoying but she didn't know anyone else in the neighbourhood who was her age, so she ended up hanging around him when she was completely bored a few times. She didn't like boys much and he was one of the dumbest boys she had ever met. One day, she came over to his house to watch some lame Star Wars movie he kept ranting about. Santana's jaw dropped when the prettiest girl she had ever seen came to the door.

This had to be Finn's older sister he had mentioned before several times. She was nine, much taller than Santana and had the brightest, cat-like blue eyes, along with long blonde hair. Santana was speechless when she smiled at her and there were butterflies in her stomach.

Santana was so awestruck by Brittany that it took her a while before she was comfortable enough in the older girl's presence to act normally but once she did, she became closer to Brittany than she had been with Finn. The trio soon did everything together, even though Santana secretly would have preferred if it was just her and Brittany. Finn began to pout and complain about the two girls always leaving him out of things.

Fast forward more than ten years later and an eighteen year old Santana was nervous when her childhood friend Finn was calling up the Latina to ask if she wanted to hang out with him and his sister on a summer day.

"Whatever, Finnocence. I guess." She mumbled into the phone disinterestedly. She and Finn moved in different circles in high school and Santana still found him irritating half the time but he was one of the popular jocks and she was a cheerleader, so at least they had their popularity in common.

She had nothing better to do that day other than paint her nails and maybe just maybe part of her was nostalgic for weekends at the Hudson house and lame movies. Carole and her boyfriend Darren had always treated her like family. There was the sound of giggling in the background as someone seemed to grab the phone out of Finn's hand and a girl's voice.

"Oh wait, my sister's back home from college on vacation and wants to say hi..."

Santana swallowed hard, heat rising to her face as her nervousness took over. She had always had a massive crush on Brittany but had been too terrified to admit it to the older girl. She felt like there was no way someone as angelic as Brittany could ever love her back and now that she was in college, she was even further out of her league.

"H-hi..." She stuttered nervously, cringing at herself for how shy she sounded. Brittany was an incredibly gorgeous girl and even though Santana tried to date other girls in the past, she couldn't get the freckled, blonde she knew since childhood out of her head.

"Hi Santana!" Brittany chirped casually, "It's been a while, Santana. I missed seeing you."

"I m-missed you too."

"So are you coming? Finn and I have the coolest place ever to take you to."

"Sure. I'll be ready," Santana tried to ignore how the butterflies were fluttering again like crazy. She was so nervous about going out with Brittany, even though it wasn't as if the three of them hadn't been out countless times together before. "Where are we going?"

"It's a secret," She teased with another soft giggle, "We'll pick you up in ten minutes, okay?"

Santana began to panic as soon as she ended the call and spent what felt like a million years primping in the mirror, staring at her reflection and making sure her straight black hair and makeup looked amazing because there was no way she'd let Brittany see her looking like a mess. Her tight jeans, black leather jacket and boots would have to do.

There was an insanely bright pink G-Wagon parked in the driveway of the Lopez mansion a little later than Brittany said she'd be. Finn and Brittany could never do anything on time. The blonde girl saw Santana watching them through the window and waved at her from the driver's seat. Santana tried to calm the butterflies she felt again but quickly made her way down to her friends after her mother shouted at her telling her the Hudsons were there. Finn fist-bumped her in greeting and Brittany grinned cheerfully when Santana climbed into the backseat.

"Hi Guys."

"Hi, Hot Stuff!" Brittany quipped, meeting her gaze head on.

Was she flirting with her or what? Blue eyes were narrowed, long lashes fluttering and it felt like Brittany was eyeing her appreciatively but maybe that was just wishful thinking on Santana's part. "Wow, you're all dressed up. It's just us, Silly. Remember you and I used to play naked in the splash pool?"

Santana blushed deeply, squirming as she snapped her seatbelt on and trying not to look as flustered as she felt. Finn just laughed awkwardly, his hoodie pulled over his head because he was being driven in Brittany's Barbie pink car. Of course Finn, being Finn also was completely oblivious to Santana's huge crush on his sister.

"I've also seen you in Hello Kitty pajamas, Santana. You look great in that leather jacket though."

"You too. You look... nice." Santana responded, cursing herself for not having a better line. Brittany was wearing an adorable pink shirt with black cats on it and jean shorts, her long hair in beachy waves. She was even more beautiful than Santana remembered her being.

"Um, Britt... you might want to pay attention to the um, road. Getting kind of dizzy." Finn pointed out as Brittany swerved wildly and drove like she was flying. Santana started to feel a little disoriented herself. Brittany was the craziest driver she knew and she'd get distracted by anything.

"I think we just drove past here." He mentioned as it felt like Brittany had circled the same block a few times."

"Oops, sorry. I had my head in the clouds. This happens all the time." Brittany spoke in a dreamy voice but at least they were finally on the highway again.

"It feels like I'm being kidnapped by Barbie." Santana joked as Brittany drove along in her crazy, girly car for twenty more minutes and Finn kept making his usual dad jokes, bopping his head to some pop song Brittany was playing. There was an easygoing, light vibe like how it always was with the Hudson siblings and Santana found herself enjoying how relaxed it was with them, even though it was hard to focus on anything other than her attraction to Brittany.

"Ohh remember when we used to play Barbies?" Brittany glanced back at her in the rear view mirror, beaming. "Finn used to be really into that too."

"Hey now, let's keep that just between us," Finn chuckled nervously as Santana snickered. "It was just fun making up stories."

"You set my Ken doll on fire." His sister giggled, catching Santana's eye again and pointedly staring at her. It was true that Santana had been insanely jealous of watching Brittany being obsessed with that doll when she was eight and set it on fire in a fit of rage. Santana slumped down into her seat in embarrassment as the two smirked at her.

"Oh look, we're here!" Finn announced happily. Santana blinked in complete confusion as they pulled into a gas station. "It's the most fun place ever. Britt and I go here all the time for fun."

"It's... a 7-Eleven..." Santana said flatly, blinking in confusion as Finn and Brittany got out and encouraged her to follow them. It was probably the biggest 7-Eleven Santana had ever seen. When Finn kept ranting about some cool place they wanted to take her, Santana expected something way better than this. She was unimpressed.

Finn kept looking over at Brittany like an excited puppy to see her reaction. Ever since Santana first met him, Finn always looked up to his older sister. Brittany reached up as she was shorter than him even in her high heels and ruffled his brown hair affectionately.

"Yeah, I know. Isn't that great?" Brittany gushed to the black-haired girl. Santana nearly tripped when her hand grabbed hers as they walked over, forgetting about anything disparaging she was going to say as she saw how excited Brittany was. She didn't understand why Brittany was holding her hand but she wasn't going to pull away.

"Um... it's something." Santana cleared her throat, trying not to hurt the girl's feelings.

"This is the best place ever to get snacks other than the dollar store. Hey look, Brittany, chips are on sale!" Finn grabbed several huge bags of potato chips, shoving them into a basket and Brittany made a delighted sound. Both of their eyes went big as they saw all of the snacks on display in the aisles. "We'll need to get all the discounted Halloween chocolates too."

"Yep and don't forget ice cream. We're running low on chocolatey caramel vanilla swirl and that's my favourite." Brittany added with a nod.

For the life of her, Santana couldn't understand what the two were so happy about but they moved around at a fast pace and talked like they were seasoned experts. Only they understood each other's brand of weirdness but Santana couldn't help but find Brittany's eccentricities cute rather than off-putting. Her face fell and she tried not to look disappointed when Brittany let go of her hand to go inspect a huge bag of pink and white marshmallows Finn was holding up.

"Are you guys done yet?" Santana crossed her arms over her chest, not keeping the irritation out of her voice after the two of them spent the next ten minutes debating which snacks they should get.

"Don't worry, it's not over just yet. The best part is about to come." Brittany winked at her and Santana's knees felt a little shaky.

"Oh you're in for a treat, Santana. I can't believe you've never tried this stuff before." Finn sighed, in ecstasy as he bit into a chocolate bar.

"I can't either." Santana deadpanned as he and Brittany lead her over to the counter where you could buy nachos and slushies. Sure, Santana had been to a 7-Eleven once or twice in her life but she was completely out of her element.

She liked to live in luxury and gas station food wasn't exactly glamorous. She cringed, thinking of the germs the food was probably full of and her eyes darted around, hoping that no one from her high school was seeing her there. This was what she got all dressed up for? Brittany handed her a set of nachos and added cheese to them for her. Santana stared at them scornfully but her face softened when Brittany looked at her encouragingly.

"Yeah, they're good. The cheese does kinda make me gassy though so you might want to roll a window down just in case." Finn added as an afterthought and Brittany laughed loudly, elbowing him in the side while Santana just stared at him, repulsed. Santana could never really understand the dynamic between the Hudson siblings.

"It's delicious, trust me. Do you want a slushie too?"

"Ew - I mean no - no thank you. They're way too sweet." Santana made a face as Finn began sipping the blue extra large slushie he was holding and Brittany just shrugged, sipping from her smaller red one as she paid for their things. Santana offered to pay for hers but Brittany didn't let her. They also grabbed some hot dogs with everything on them for Finn and he made sure to cover his nachos with every topping imaginable.

"What the fuck, Flopson?" Santana groaned when Finn bumped into her, spilling some slushie on her expensive shirt. She could practically scream in frustration. That was the last straw. She hated feeling unclean. Seeing the puddles of spilled slushie and dried on coffee on areas of the floor everywhere she went only made her feel more repulsed.

Santana slipped away into the aisles, asking or rather demanding with a snarl that Finn held her tray, along with his own, much heavier one. The boy just blinked at her in confusion but didn't argue as he knew not to argue back with Santana when she was in one of her moods. She was annoyed at watching Finn stuff his big face the whole time they stood up by the counter and flustered about having to hang out in this gross, tacky place in the first place.

"Whoa - what the fuck..."

She was surprised when she felt arms wrap around her and was about to deck whichever pervert grabbed her but she heard Brittany's soft voice in her ear and blushed, feeling her curves pressed against her back.

"Are you okay, Santana?" She giggled as Santana turned around to face her with a flustered expression. "Not too traumatized?"

So Brittany had noticed her lack of interest after all. Santana didn't want to upset the girl by admitting she wasn't into gas station food.

"I'm not..."

"I'm sorry about your shirt. You know my little bro gets clumsy sometimes. You can borrow one of mine and I'll help you get the stain out."

"T-thanks."

"You look really weirded out. I'm sorry if we made you uncomfortable by taking you here. If you want, I can take you back to our place or somewhere else."

"It's fine, Brittany. It's just not exactly... fancy."

"I know you only like your fancy pants five star restaurants but thanks for coming with us anyway," Something about the way Brittany was standing so close to her, whispering in her ear was making Santana forget to breathe. "For what it's worth, you look really hot in that outfit. It's turning me on."

Santana yelped, looking around to make sure Finn wasn't hearing them because she was so flustered by Brittany. She was relieved that they seemed to be alone, out of earshot of the other customers. She practically overheated when Brittany slipped sneaky hands into the back pockets of her jeans and gave her ass a squeeze.

"Brittany! What are you doing?"

"Sorry, you just looked so cute. I had no choice." Brittany winked again, her octopus arms disappearing from around Santana as she finally moved away. Santana took a deep breath, summoning all her courage and grabbed Brittany's hand, pulling her in close and glared at her.

"Wait, Brittany, I...look, are you... are you flirting with me? Just stop leading me on, okay, if that's what you're doing because... I really like you, way way too much and I don't know if I should be telling you this but... "

Instead of answering, Brittany leaned in close again, cupping Santana's jaw to tilt her face upwards and kissed her. Santana tensed at first, not expecting it. It wasn't that long of a kiss but Santana accidentally dropped the bag of jelly beans she was holding for Brittany and melted completely at the touch of those soft lips against hers. She could taste the cherry flavour from the slushie and to her surprise, it wasn't the least bit unappealing on Brittany.

"Mmm... making out in the 7-Eleven chip aisle. So sexy." Brittany joked as they parted and Santana's heart continued to beat rapidly. Santana couldn't help but laugh and Brittany took her hand again and lead her away.

"Whoa, what's going on? Were you guys kissing just now?" Finn raised an eyebrow, grinning at them playfully as he handed them their food and they sat around at a table. He whistled at them, chuckling when neither Brittany or Santana denied it, the black-haired girl hiding her face.

"Maybe." Brittany smirked back at her brother, stealing a bunch of Santana's nachos and the Latina didn't protest at all. Finn made a face at the two as he finally seemed to realize that there was something going on between his sister and the dark-haired girl.

"Huh..." He got out, finishing his third hot dog after the huge set of loaded nachos he had demolished. Finn had always been overprotective of Brittany and Santana wondered if she should start running when the big guy frowned, furrowing his brows. "That's just... wow...I guess I always knew Santana had a huge crush on you."

Santana could not have been more embarrassed as the siblings smirked at her.

"Brittany..." Santana mumbled in a warning tone, her eyes narrowing when the blonde gave her a sticky kiss on the cheek after biting into a nacho. She loved kisses from Brittany more than anything but something about all the cheese and salt was making her skin crawl. Finn and Brittany were messy eaters, especially the boy and Santana was the complete opposite.

"Best first date ever?" Brittany asked jokingly, whispering into Santana's ear. Santana forgot how to speak when Brittany kissed the tip of her ear. She realized that Brittany was kind of right... it had been like a first date for them almost. A very weird one but at least she still got a few kisses out out of it from the prettiest girl in existence.

"You got that right." She smirked, wrinkling her nose at the smell of nacho cheese on the girl but thinking she was adorable all the same as they finished their food - Santana barely touched hers, much to Finn's confusion, giving most of it to the siblings to finish - and Brittany lead them back in the direction of her Barbie car, her arm wrapped around Santana's shoulders.
