A/N: Thank you to the guest who left that really awesome review! Yes, you're right, things are really heating up between these two...

This chapter will be a little longer than the others. There'll be more Brittana development/UST/Santana jealousy shenanigans.

Santana rolled her eyes, a small smile coming to her lips as she could hear the blonde singing some eighties pop song the entire time she was in the shower after Santana had finished hers and it was the blonde's turn. Minutes later, Brittany walked into the adjoining bedroom when Santana was in the middle of pulling an oversized t-shirt over her head and shorts to sleep in. She jumped and felt heat rush to her face, wondering just how much of her body Brittany had actually seen.

"Brittany!" She let out an undignified squeak.

"Oh, oops! I'm so sorry, Santana!" It seemed like Brittany's cheeks were tinged with pink as well and her lips were parted in surprise when Santana finally mustered the courage to look at her face again.

Santana swallowed hard because the girl was fresh out of the shower and wearing the same combination of Santana's old, tiny black pajama shorts and faded tank top that showed off that tantalizing glimpse of freckled skin low on her hips again. Santana felt heat crawling up her neck, noticing how cute and young Brittany looked especially when she was all bare-faced without her usual makeup. So this was what she was going to be having to get used to when sharing a room with Brittany.

"It's… no problem. Just, you know…if we're going to be sharing this room for a while, we're going to have to be careful about giving each other privacy."

Brittany just nodded, humming in agreement but she was giving Santana these flirty bedroom eyes that made the Latina have to turn her back to her and create some space between them as she took a deep breath. What was up with Brittany and her seductive ways? It was like this woman couldn't turn her flirting off.

"So here's how we're gonna do this…you take my bed and I'll sleep on the inflatable one." Santana said in a flustered tone when she had finally got the air mattress set up and made it up with sheets and pillows. The thought of sleeping in the same room as the girl with Brittany just a few inches away was making her heart beat so fast.

No, no, be cool, Lopez. You've had so many other hot blondes in this room wearing far less…no big deal. Don't panic.

"Are you sure, Santana?" Brittany asked, tilting her head to the side.

She was cradling that huge grey tabby cat in her arms again and he was watching Santana with his usual mean mug, his tail flicking back and forth while Santana cut her eyes at him. Santana didn't like the idea of having a cat in the apartment at all but they were just lucky Mercedes still had leftover litter and cat food from the last cat she had fostered not that long ago.

Her eye twitched when Brittany dropped Lord Tubbington onto the bed and he curled up but she didn't say anything. All that grey fur all over Santana's bed…

Santana knew that if Mercedes, Quinn or their other friend, Tina had stayed over in her room, she would never ever have given up her bed to them but Brittany was different somehow.

"Yeah, yeah, I said you could have it, didn't I?" Santana mumbled in a mildly agitated tone, gesturing towards the bed. She hated how she just kept doing nice things for this girl as if she no longer had control over her own will anymore. In the back of her mind, she could envision Mercedes' smirking face and hear the obnoxious sound of her making the noise of a whip. "I'm not a complete barbarian who would force a young girl to sleep on the floor on an old blow up mattress."

"That's because you're a true lady," Brittany grinned at her, those so very blue, blue eyes of hers twinkling. "You and Mercedes both. You have good manners."

Santana scoffed, laughing sarcastically. Most people called her an uncouth bitch with a sharp tongue who just couldn't be soft and polite with anyone. When she thought of ladylike, she thought of Quinn who was all uptight and aristocratic, descended from a long line of WASPs and butter wouldn't melt in her mouth. "Me?! A lady? Who says that anymore? I don't know any ladies."

Brittany just smiled and yawned, getting settled into Santana's black silk sheets. "It's your actions that count. I'm just glad that there are still good people left in this part of the world. Well, goodnight San."

It was strange to be thought of as a good person in Brittany's eyes when everyone else saw Santana as this complete cold-hearted bitch. She tried to ignore how soft and angelic Brittany's face looked while sleeping without her signature makeup and with her cat curled up next to her.

Despite her annoyance with the chaos that had been going on in her life since Brittany had appeared, Santana couldn't ignore how sweet Brittany could be at times. She somehow felt comfortable talking to her in a way she had never felt even with Mercedes, who was her oldest friend. It somehow felt calming to have her presence around and Santana succumbed to sleep almost as soon as her head hit the pillow, not half as restless as she normally was at night.

"So I can really just find information about anything on this thing?" Brittany asked, staring in amazement at the old laptop Mercedes had handed her. The shorter woman nodded at her with an amused smile. "Even UFO sightings? Who invented sweaters?"

"Yep, it's all here. I can't believe you've never used a laptop before, Brittany. How can that be possible?"

Santana had come out of her room that morning to find Brittany staring at the device with pure astonishment and just shook her head in mild exasperation.

She hadn't been all that sure about leaving Brittany alone in their apartment all day even though the blonde gave her this sweet smile and assured her that she would be fine. Mercedes and Santana left Netflix on for her. Brittany still was getting used to the binge watching thing as she couldn't seem to wrap her head around it.

"Whatever you do, please don't touch anything if you don't know what it is." Santana begged, praying that their TV wouldn't explode and hoping that one of their other appliances wouldn't be broken by the time she got home if Brittany got into one of her curious, exploratory phases. Brittany was eccentric to say the least and there was no telling what she would do.

Santana cautiously crept back in to the apartment, unable to concentrate on anything at work that day as her mind was consumed by thoughts of Brittany, wondering what the blonde was doing. She nearly jumped out of her skin when she walked past her bedroom that day after work and heard the faint sounds of some woman moaning. Come to think of it, the sounds were very familiar, almost like…

"What the… ?!"

Santana barged into her bedroom and found Brittany fully clothed, holding the laptop Mercedes had lent her in her lap and staring at it in confusion. When Santana leaned in closer to look, there was some dude getting it on with this blonde, big-breasted woman on the screen and by the looks of it, they were both really into it.

"Santana, this is so weird. People put porn on this internet thing?" Brittany giggled. "I just typed in "hot blonde girl having fun" because I was looking for things to do in Lima and this video came up. It's not very good, though. I've seen better on VHS."

Santana hoped the blush she felt rising up her face didn't show on her dusky complexion.

"Yes… it's kind of the main reason why a lot of people use the internet in the first place. You can't talk about…and definitely not watch porn in front of people. Also, don't just type in anything into the search bar. Brittany, please just turn that thing off."

"Oh wow, you look really flustered, Santana. How do I turn it off again? This thing is so confusing."

"Here, let me help you," Santana scooted over next to her on the bed with a sigh and took the laptop out of her hands. She scrambled to exit out of the browser as the moaning from the video got more intense. "I hope this doesn't give it a virus."

"Virus?" Brittany echoed, confused. Oh brother...

Mercedes walked by in the hallway at that exact moment, hearing the loud, unmistakably lewd sounds emanating from the bedroom and shook her head when she saw Santana with Brittany on the bed holding the laptop together. She mumbled something that sounded a lot like "You all need Jesus."

"Whoa, it's not what it looks like. I was just… helping Brittany with this!" Oh fuck, that sounded wrong…

"Oh, I'm sure you were helping her, Satan." Mercedes smirked and Brittany just blinked at both of them in confusion while Santana glared at her long-time roommate. Santana could scream. She was going to kill that church-loving, God-fearing woman.

Several men - many of them much older which made it that much creepier - were giving Brittany the eye and a few froze in their tracks, just staring at her in amazement as the three women walked through the mall later that day. Of course, the tall girl didn't even notice and just smiled at everyone in her usual friendly, perky blonde way.

"What the hell is wrong with people?" Santana grumbled under her breath. Mercedes heard her and shook her head with a sigh at the creeps, expressing her agreement with the Latina.

"That makeup she's wearing really doesn't help… they think she's a baby prostitute…" Mercedes whispered into Santana's ear when Brittany was out of earshot. "It would be alright for a few decades ago but now it just looks crazy. She really needs help. Maybe more help than we can give her but I'll try."

"Yeah, you're right about that."

"Why don't you just let me take over this time, Santana," Mercedes suggested, giving Santana a smug smile, "You don't know much about fashion - don't give me that bitchy look, you know it's true - and I'm obviously the queen of it, so I'll know exactly how to fix her up."

"First of all, that's just a lie - you know my fashion sense is awesome, 'Cedes. Secondly, fine, have at it all you want but just admit that you really just want a giant Barbie doll to play dress up with."

"Maybe. Having a life size doll is pretty fun," Mercedes shrugged, unfazed. "Why can't I get a little fun out of this too? C'mon, Brittany. I know exactly where we should go first. Santana, do whatever you want in the meantime. I'll text you when I'm ready for you. Give me your credit card, Lopez."

"Alright, whatever." Santana agreed, not liking Mercedes bossing her around but handing her the card without another argument. At least Mercedes would have the job of answering Brittany's weird questions and dealing with the funny stares people gave her while Santana could enjoy some peace and quiet without anymore chaos for a few hours.

"Oh, Satan, I think you're gonna want to see this!" Mercedes smirked at her, walking out of the dressing rooms. Mercedes had texted her a few hours later, telling her to meet them in some bougie store after she had taken Brittany for a haircut.

Santana would do a lot for the blonde but she drew the line at going into a dressing room with her. She didn't know if her hormones could handle that, knowing how her body was already acting all weirdly in response to Brittany. That would have to be a job for Mercedes.

"Yeah, what is it?" Santana grunted in boredom, not looking up from her phone. What did she care what outfit the woman changed into? Brittany was eccentric, way too innocent, too eighties, too cat-obsessed and…and…

Completely stunning.

"What do you guys think? I look so modern!"

When Santana finally looked up, her breath caught in her throat. She had never seen Brittany in this kind of light before. She looked like a supermodel as she walked out elegantly and twirled to show off every angle.

Her long, blonde hair looked soft, flowing down to her shoulders in soft, tousled waves rather than being frizzed up in that dated style and her makeup was subdued, with a light pink lipstick and soft eyeshadow, her feline eyes emphasized perfectly, as opposed to the overly heavy, dated makeup she wore before. It really brought out the intoxicating sky blue of her eyes. She was wearing small, classy looking gold earrings rather than the massive ones that looked like they were popular forty years ago.

More than that though, it was the stunning dress she was wearing that made Santana feel practically dizzy as she admired her beauty. Her eyes raked over her tall, lithe form in the shimmery gold dress that showed off her oh so long legs.

Mercedes had given her such a complete makeover from head to toe and she could pass for any other woman from Lima. Now that the baggy clothes, legwarmers and graffiti coats were gone, it was clear that Brittany was a beautiful woman. It was official: Brittany S. Pierce was the most gorgeous woman on the planet. Way more gorgeous than any girl who Santana had ever met from Lima or elsewhere.

"So, how do I look? Is it bad?" Brittany asked, biting her lip with a slightly worried look as Santana just gaped at her speechlessly before collecting herself. "Is my hair too flat? They told me a perm would be a bad idea."

"No, it's not bad…at all. It's um… you look really good, Brittany." Santana coughed, feeling all the blood rush to her face. Brittany gave her a soft, bashful smile in return.

Mercedes caught her eye and shot her that smug, knowing look she had been giving Santana all the time these days regarding Brittany.

"More than just really good, right? You might want to pick your jaw up from the floor and get the little hearts out of your eyes, Lopez," Mercedes smirked, elbowing Santana in the ribs as they watched Brittany walk back into the dressing room. "Some people might get the wrong idea."

"Shut up."

"Just admit it, Satan - I did a fantastic job with her, didn't I?" Mercedes was giving her that self-satisfied smile that Santana couldn't stand but she couldn't argue with her on that.

As it turned out, other people were noticing Brittany as well now that she was dressed so amazingly. It was hard not to, Santana supposed.

"Whoa, now look at you!" The shop assistant, a dark-haired guy who looked to be around their age wolf-whistled at her. Santana glared at him, noticing how the guy didn't take his eyes off of Brittany's ass. Just Santana's luck that they'd find the only straight dude employee in all of the clothing stores in the Lima mall.

"So, where are you from?" He asked, making conversation with Brittany. "I just have a feeling you're from out of town. Is that an accent I hear?"

"She's from Antarctica!" Santana snarled, a little more aggressively than intended as she butt into the conversation. She really didn't like the way the guy's eyes were focused on Brittany's cleavage practically the entire time and he was just about salivating over her. What a sleaze…

"Oh, how exotic! Do all girls from Antarctica look like you? This might be a little too forward of me but you're just such a babe. We should get to know each other better."

"Oh, thank you!" Brittany blushed visibly and giggled.

"It's Brittany, right? I heard your friends call you that. Would you like to go out on a- ouch!"

The guy jumped, startled and yelped in pain. So maybe Santana's Swiss army knife she had been playing with had accidentally jabbed him in the back pretty hard, stopping him in mid-sentence. Just purely a coincidence, for all anyone knew.

"Oops, sorry! My bad!" Santana snickered, pushing the sharp object back into her bag. So maybe she had sabotaged Brittany's romantic life again, kind of on purpose too, but that guy was just wrong for the blonde. There was no way some random sleazy dude in some clothing store would be Brittany's future husband in any dimension.

She saw Mercedes shaking her head at her and the shorter woman made a judgmental, disapproving little noise in the back of her throat.

"You're such a bitch." She mouthed at Santana, looking like she was struggling to hold back laughter.

Santana did her best to ignore her but flipped her off anyway, smirking at her friend. Meanwhile, Brittany was totally confused. Santana's ears perked up when Brittany called her over a few minutes later when she was in the dressing room by herself while Mercedes was wandering around the front of the store.

"Santana? Are you out there?"

Santana sighed, nervously looking around and wondering if she should call for Mercedes. It was almost like her old friend was doing this on purpose to her or maybe the fates just had it out for Santana because only she would end up in a situation like this. Eventually she decided to just help Brittany out herself because she couldn't very well ignore her.

"Um, hi…" Santana mumbled awkwardly, cautiously pushing the curtain aside and trying to keep her eyes averted to be respectful. God, there were butterflies that had no business being there going crazy inside of her right now. "You're decent, right? I didn't want to walk in on you…naked or anything."

"It's fine. I think the zipper's stuck…can you please help me take this off?" Brittany asked in a shy voice, trying to reach behind her back and biting her lip, frustrated when she couldn't get the zipper to go down.

Santana's eyes shot open.

"Whoa! Um…sure… if you think that's appropriate, Brittany."

Damn, her fucking hormones that seemed to think she was a fifteen year old teenager again. Her breaths became more uneven, her heart pounding in her throat at the pale, freckled skin of Brittany's delicate back that was exposed as she helped her take the dress off. Her skin felt so soft on the areas where Santana's hands brushed accidentally though she tried to avoid any gesture that seemed too intimate. Santana was beginning to wonder if this was some sneaky seduction technique Brittany was trying to use on her. If it was, she had to admit it was definitely working.

She had to put some distance between them fast. Especially when the dress was unzipped all the way and the only thing keeping Brittany clothed was her holding the front of it against her chest as she turned to face Santana.

"Santana, I…" Brittany was way too close. Santana could see all of those cute freckles on her face and her eyes were this darker, more opaque blue, reeling Santana in so effortlessly. Santana's eyes fell to those pale, tiny petal pink lips and then…

"Whoa, what are you two up to?" Mercedes had walked in and pulled back the curtain, holding a few more dresses on her arm and shaking her head at the sight of them. "I shouldn't be surprised. I leave you two alone for two minutes and this is what happens? Dayum, Santana you have more game than I thought but you both really need Jesus."

"I officially hate you…" Santana grumbled at Mercedes' teasing, her voice much higher pitched than normal as she tried to get her breathing and heart rate under control. Damn, that was close. She was both angry and relieved by Mercedes interrupting them, wondering what could have actually happened if she hadn't walked in on them at that moment. Brittany's face was so flushed, her cheeks a pretty pink and the disappointment was obvious in her expression.

"Wow, you're even grouchier than usual. Love you too, Lopez!" Mercedes mockingly pretended to blow a kiss at Santana as she turned around, stomping away and left the two of them alone in the dressing room.

Now that she was wearing normal, pretty clothes, Brittany was turning heads wherever they went for much more positive reasons.

"Ohh, look at you, Miss Girl!" Mercedes smirked proudly, nudging Brittany who blushed with the flattery.

"So what did you think of him? He seemed really into me." Brittany piped up in a dreamy voice a few minutes later.

"I thought he was okay," Mercedes shrugged. "He was handsome and he was definitely flirting with you, Brittany."

"I don't like him," Santana said gruffly. "You can do better. He's not the kind of guy Brittany should choose, Mercedes."

"Why not?" Her lawyer roommate and best friend asked in a calm voice. Santana hated how reasonable and logical Mercedes sounded. "Isn't she looking for a guy? So why isn't he good enough?"

"Are you kidding me?! I shouldn't have to even answer that." Santana snarled. Mercedes just looked at the Latina as if she had gone insane.

"You look like you're plotting to go back there and murder him." Mercedes remarked in a deadpan voice, raising an eyebrow at her while Brittany was oblivious to the dark aura that was emanating from Santana. Santana hated how Mercedes knew her so well that she could expose all of her embarrassing secrets if she chose to.

"Maybe so…he'd deserve it... " Santana mumbled, ignoring the way Mercedes kept casting these amused looks her way. Santana was lifting what felt like a million pounds of things in shopping bags. "What the fuck, how many things did you two buy? Why do I have to be the one to carry them?"

"Just a few things Brittany needs," Mercedes shrugged nonchalantly. "Maybe something for myself too… Sam and I do have a big date coming up and you owe me. What are you complaining for? You wanted her to look good, right?"

"If you maxed out my credit card I won't hesitate to ends you, 'Cedes."

"No you won't," Mercedes rolled her eyes sassily, glancing down at her phone as it made a noise. Brittany jumped back, staring at the phone in surprise. She always seemed totally confused by cell phones. "Hey, the gang wants to meet up tonight. We should introduce Brittany. It would help with her love life if she meets some new people."

"Hmph," Santana just grunted in irritation. She didn't really like the idea of introducing Brittany to her friends, knowing how many weird things came out of the girl's mouth and the guys they knew were total dorks, definitely not worthy of Brittany anyway. Still, Mercedes was technically right and it would sound weird if she tried to stop them. "Alright, fine. We'll go to karaoke with them tonight."

"You do know what karaoke is, right Brittany?" Mercedes asked in a flat voice, arching an eyebrow as she turned to the blonde.

"Of course. It's my favourite thing ever!" Brittany replied cheerily while Santana gave her a perplexed glance.

"So remember what we talked about. Don't say anything weird, or ask too many questions. Just be cool, Britt." Santana told her quietly. At least the blonde's style was normal and attractive now so she'd no longer be causing eyebrows to be raised wherever she went.

"Whoa! Hot dayum! This your new girl, Lopez?"

Santana gave Artie a murderous glance as he whistled at the sight of Brittany walking into Breadstix with Santana and Mercedes. The rest of the group, including Finn, Sam, Quinn, Mike and Tina waved at them, all looking at Brittany in interest.

Sam kissed Mercedes on the cheek, putting his arm around her as she sat next to him in the booth. They were always this sickeningly sweet couple that made Santana want to gag at times but she couldn't deny that they were happy with each other in a way that Santana had never seen either of them before with anyone else. It helped that they were both the biggest divas she knew other than herself so they probably had that to bond over, Santana thought.

"No, she's…she's just a roommate. She's a friend from um, out of town so she'll be here for a few weeks." Santana explained, feeling awkward and flustered at the thought of Brittany being mistaken for her girlfriend yet again. Why did literally everyone think Brittany of all people was Santana's girlfriend? Everyone at the table gave her this doubtful look as she said it.

"Guys, guys, you have to hear this Rachel Berry song!" Finn announced, staring down at his phone after everyone introduced themselves to Brittany.

"Oh my God, she's so overrated," Santana remarked as the rest of the table groaned at Finn, as they had heard him say something like that a million times already on that same night alone. Santana was always irked by people thinking Rachel was the best singer when they should have been worshipping her own singing instead. "I can't believe you're still completely obsessed with some Broadway chick who had a few hits then disappeared like forty years ago."

"Finn here is obsessed with everything about the eighties, Brittany, even more than you seem to be. If he had seen what you looked like a day or two ago he would have flipped out and gone to fanboy heaven." Mercedes said with a grin.

The excitable giant of a man grinned and nodded enthusiastically at Brittany while Santana scoffed. Finn was like a big annoying puppy with a gassy toddler facial expression and she really didn't need Mercedes to get him started on the eighties talk because he would literally never stop.

"Have you heard of Rachel Berry, Brittany?" Finn asked, looking at the blonde expectantly.

Brittany's eyes darted around nervously. She tried to keep calm and not give herself away.

"Um… yeah, she's my- I might have…" She started to say awkwardly.

"Everyone's heard of Rachel Berry, Finn. We've all seen those documentaries." Tina eventually snapped. Santana was so grateful for Tina's bitchy attitude for once if it meant she could stop the fanboy rant Finn was about to launch into.

"Hey, Britt! Watch this." Santana gave her a smug smile as she went on stage to start off the singing a few moments later. She would admit that she was definitely trying to show off a little in front of Brittany and had been searching for her face in the crowd every so often, feeling pleased with herself at the look of awe on the blonde's face.

Santana rasped her way through the Alanis Morissette song she had chosen, then Finn and Mike took over with some Phil Collins song that involved a lot of epic drumming, and Mercedes sang Summer Nights from Grease as a duet with Sam. After they had all finished their performances, Brittany took the stage, singing a song that Santana would never admit in a million years had been her favourite love song for some time - "I Think We're Alone Now" by Tiffany.

It was so sweet in comparison to the angsty rock Santana had chosen. Brittany began to sing in her clear, light voice that was quite angelic but perfect for a catchy, fast-paced eighties pop song. She sounded exactly like the pop singers from the time and acted out the body language perfectly.

She glanced in Santana's direction as she began to sing the romantic lyrics of the song, looking straight into her eyes. Santana's heart was beating so fast at the idea of Brittany singing a cute love song to her. Even though she had shot down Brittany's advances before, she couldn't help but totally melt at this gesture. None of the girls she had been with had ever done anything that romantic and special that was just for Santana before.

No…she couldn't allow herself to think of Brittany in this light. All girls were the same. All girls were fake, money hungry snakes. No one could be trusted and Santana wouldn't fall into that trap again. Santana was no fool.

Brittany was giving her this timid, secretive little smile as she approached her afterwards that was making Santana think all kinds of crazy thoughts like how she just wanted to risk it all and kiss her right there in front of everyone.

"Did you like it, Santana?" She asked in a small voice, still beaming at the Latina. "Sorry, I know you probably don't see me that way… and you made it pretty clear that you don't want a girlfriend and you can totally tell me to back off if it's too much but the song reminds me of you…I just wanted you to know that I really…"

They were interrupted by an annoying male voice and Santana looked up with a snarl as a muscular, brown-haired guy who looked like a footballer was standing right in front of their booth. Way to ruin the moment…

"Hey, you were totally amazing! Damn girl, you can sing!" He grinned at Brittany with this dumb look on his face. Santana fought the urge to throw her glass of water in his face. "You're totally gorgeous too. Can I take you out sometime?"

Brittany looked taken aback but her cheeks flushed a little from all the compliments. She glanced over at Santana with those innocent, trusting eyes as if asking for permission and Santana just shrugged, crossing her arms over her chest and glaring daggers at the guy.

It wasn't as if she was Brittany's keeper or girlfriend…what did she care whether some guy wanted to take her out? Still, she felt this awful, sick feeling in her stomach that got worse as moments passed. She tried not to care about the sad, confused look Brittany was giving her. When Santana said nothing for a long moment, Brittany turned to the guy with a smile that didn't meet her eyes. This was what the blonde had been looking for all along.

"Sure, I'd love to."
