But you're My Best Friend

Chapter 1

Santana and Britney had been best friends for years. They had grown up together, deciding to be best friends as soon as they met in the 4th grade when Britney had moved to Lima, Ohio. As they got older Santana would often retell that start of their friendship as "god laying a hand" on the two and they instantly became inseparable. As a result of this close friendship the two girls knew every detail and characteristic of the other girl's life. There was one thing that Britney was unaware of when it came to Santana though. Santana was holding on to a huge secret, probably the biggest secret of her life. The one and only thing that Santana had never shared with Britney was that she thought she may be bi-curious.

Both girls, being seniors in high school, had many different partners throughout their high school careers all of which were male partners. Santana had never kissed a girl before and as far as she knew neither had Britney. She was pretty confident the blonde had never done such an act because she was certain she would have told her as soon as it happened. Not that Britney wanted to kiss a girl, or at least not that Santana knew she wanted to kiss a girl but that it was just Britney's personality to want to tell the Latina everything that happened in her life.

Santana had always believed herself to be straight up until one fateful night during their freshman year…

FLASHBACK

Santana and Britney had just gotten into high school, each girl was equally nervous about this new adventure called high school. They both had a desire and want to rather popular in high school and they were under the impression that the only way to do that was to join the cheerleading squad, affectionately known as the cheerios. They were extremely lucky to have made the team seeing as they were the first two freshmen in several years to ever make the squad or rather ever since Sue Sylvester became Coach of the squad.

The day of the auditions they were standing in line next to the other hopeful girls as Coach Sylvester walked down the line of girls.

Sue: You all sucked! I cannot believe you would even think you had the slightest possible chance of being allowed on my team after the crap you displayed for me today. However, I do have two open slots to fill and Fake Boobs and Dumb Blonde over there are the only two whose pathetic excuse for an audition piece sucked the least! Congrats to Latino and Porcelain; as for the rest of you get out of my sight, just looking at you is causing me to vomit a little bit in my mouth.

Britney looked at Santana and both girls mirrored the same "HOLY SHIT" expression on their faces. Not only were they excited about being the only two freshman to make the squad but this also meant that they were going to be a part of the popular crowd. HOLLA! Being popular meant one of two things: one, they ruled the school obviously and two that got coveted invites to parties, like the one they were at when Santana realized something about herself for the first time.

That night Santana will never forget because it sparked an interest in her that she had yet to shake 3 years later. Santana had arrived at the party a fashionable hour and a half late, as soon as she got there she immediately headed for the makeshift bar, as she walked towards the feel good liquid she gazed over the crowd of writhing bodies on the dance floor taking in all the recognizable faces until one face caught her eye and made her stop short. It was her best friend Britney someone who she saw on a daily basis; however something about her friend caught the Latina's attention tonight. Santana let out a shaky breath which she didn't realize she had been holding in at the sight in front of her. Britney was dancing the night away grinding against some jock that couldn't seem to keep his hands from roaming her body. She was wearing a tight fitting strapless red dress that just barely covered her arse and hugged all her curves in all the right places. Something about the sight made Santana's mouth go dry, at that moment some drunken person stumbled into her, shaking Santana out of her reverie. She had no idea how long she had been standing there mesmerized by her friend's dancing; Santana shook her head to regain her composure and continued on her journey towards the liquor bar.

After downing two shots of whiskey her mind travelled back to the vision of her friend dancing, it wasn't the first time she had to be jolted back to reality while watching her friend. There was just something about the way that she moved that always caught Santana's attention. Once again she was brought out of her daze when someone from behind wrapped their arms around her waist. What the hell? She thought but then relaxed when the person behind her placed their head comfortably in the crook of her neck.

Santana: Hey you.

Britney: Hey, what are you doing?

Santana: Nothing, just getting ma drink on. Have fun dancing?

Britney: Yea, you should dance too.

Santana: That's ok Brit; I don't want to dance by myself.

Britney: You wouldn't be by yourself you would be with me duh.

Santana: You already have a dance partner though I thought.

Britney: Oh what him? I told him to get lost, he wasn't cute anyway, so I came over here to find myself a new dance partner and I found one (giving the smaller girl a squeeze)

Santana: I don't know Brit, I'm not sure I want to dance.

Britney: Oh please San, don't make me dance by myself!

Santana: Ok, ok, just don't give me that puppy dog face; I can feel it against my shoulder.

Britney: That's exactly why I did it; I knew you wouldn't be able to say no.

Santana: Evil!

Before Santana could say anything else she found herself following the tall blonde to the dance floor. As soon as they reached the middle of the floor the DJ put on a new song which Britney squealed after realizing what song it was. Although Britney was white she had a talent for rapping or at least singing along with any R&B song and the current song she was singing along to was "Down on Me" by Jeremih. Both girls were standing facing each other letting the rhythm of the music flow through their bodies. Britney truly was a natural at dancing, the way she rolled her hips to the beat. The two girls continued to dance closely together, Santana trying desperately not to fall into another one of her dazes as she watched Britney do her thing in front of her. That got significantly harder however when Britney quickly turned around and began to grind her hips into Santana. Santana's immediate reaction was pure shock at first but she then slowly tried to follow Britney's hips as they swayed back and forth to the music against her. She wasn't trying to add any extra pressure while dancing because well she had never danced like this with a girl and she had never been the person dancing behind, so she wasn't exactly sure how to proceed. Hell, she didn't even know where to put her hands! The one thing she did know was that the way Britney was grinding against her was giving her goose bumps and sending a shiver up her spine. Were those butterflies in her stomach? It was the second time that night that Santana thought, what the hell? Her current thought process caused her to stop following Britney's rhythm. When Britney realized that Santana had stopped dancing with her she turned around to see what was wrong. Britney's blue eyes meet the brown orbs of the Latina's and the amount of emotion she saw in her eyes was hard for her to decipher. She swore she saw confusion, excitement, and curiosity in her eyes. Oh who was she kidding she had no idea what she saw.

Britney: What's wrong San?

Quick thing of something! I can't tell her I stopped because she was giving me goose bumps! Wait, were the goose bumps and butterflies because…..no…it can't be….was I getting turned on?... No! That's ridiculous! It's just the way she was dancing that's why, if it was a guy the same thing would have happened...yea that makes sense…I have never got goosebumps before though and that shiver?

Britney: Santana?

Britney tapped her friend's shoulder bringing her back to reality once again

Santana: Uh,…sorry Brit….i was having trouble standing….your, uh…..a really good dancer.

Britney: oh why didn't you say so, let's go over here then.

Britney grabbed Santana's hand and led her over to the wall and before Santana had time to process why a shiver ran up her spine simply due to the fact Britney had grabbed her hand, Britney had her pressed up against the wall continuing right where they had left off.

Santana: ughhhhhh

Shit I hope Britney didn't hear that….was that a moan? Oh my god, what is going on with me tonight!

Britney had heard it though, and to be honest it excited her. Britney had never told Santana about her adventure with a girl one night, she met Janice at a bowling alley and was amazed by her skills at knocking down the pins. She invited her on to her show Fondue for two and afterwards they ended up kissing. She isn't sure how it got started but she knew she enjoyed it. She hadn't kissed another girl since and she didn't want to tell Santana because well how would you even go about starting that conversation? Plus she didn't know how San would take it so she just told Lord Tubbington instead and swore him to secrecy. She wasn't sure what it meant that she enjoyed kissing a girl, and to be honest she didn't really care bi-sexual, straight, or lesbian, she just didn't care for labeling herself, she was just having fun!

That was a moan though, Britney was sure of it, hmm I wonder what would happen if I did this…Britney whipped around so that she was facing Santana, she made sure their bodies were pressed tightly together her hands placed on either side of Santana's face. She leaned in close to Santana's ear and whispered "Hey." The only response she received was a brief "Hi" followed by a sharp intake of air. Britney smiled to herself as she turned back around. Oh this could be fun.

Fast forward 3 years, to their summer before their senior year. That night had changed Santana's mindset. She had decided to forget about it, she credited her craziness to that of being emotional due to PMS or something like that. However, following parties she would find herself in the same position having the same feelings. Santana thought maybe Britney was doing it on purpose because it seemed like ever since that night she would do her best to brush up against her or do something that would bring about the next wave of butterflies and goose bumps. Santana had given it a lot of thought over the past 3 years with the many encounters with Britney and she had even caught herself appreciating the beauty of other girls. She had come to the conclusion that she was curious about kissing another girl. Not just any girl though, she wanted Britney.

Britney had been teasing Santana ever since that night she heard the girl moan while dancing with her. She had made it her mission to drive her crazy in hopes that she might make a move on her. Yea, she was willing to admit she had a crush on Santana, but she wasn't about to tell her that. What if she freaked out and ran away? No she couldn't lose her friendship, her friendship to Santana meant more to her than anything really. That doesn't mean she can't have fun and play with her mind. At least to see what the other girl would do. After that night she had gotten the other girl to moan several other times while dancing, Britney had also began to pick up on when Santana would stare at her or was holding her breath because of something Britney would do. In all honesty she was having so much fun torturing Santana, she just hoped that sooner or later the other girl would get the hint and make a move.
