authors note: For those who want some jealous Brittany ;) And to the guest that commented on the age difference, Santana is not 16, she's actually almost 18; that's all I will say about that issue.

Also there's been a poster made for this by a lovely lady, ohvalerievalerie . tumblr post/39748645804/brittana-underneath-it-all-x (you guys know the deal with links)

I really hope this tickles your fancies and I apologize for any mistakes!

disclaimer: I do not own Glee or it's characters.

I have no idea what I'm getting myself into – bringing a porn star to a high school party. I contemplated a lot while I was in the shower. I even drew little diagrams on the fogged up glass. Whatever happens tonight I hope it doesn't ruin Brittany's impression of me. The majority of my classmates are embarrassing and considering they will all be there tonight - it's causing odd places on my body to sweat. I think Brittany likes me and considers me a friend, but I'm not entirely sure. Maybe I'm just a girl she enjoys teasing because she knows I'll fall at her feet. I guess that kind of makes her a bitch. But she's so sweet and quirky that it's impossible to even think she has a mean bone in her body.

I dry myself off and thank god that I brought my clothes into the bathroom and that my dress doesn't have a zip. I pull my hair from it's bun and throw my head forward and back to give it that wild and wavy effect. I slide on my dress and check how it looks in the mirror. It would definitely define my curves – if I had any – but I'm still a growing woman so it's good enough. I apply some eyeliner to give my eyes that seductive effect; not that I didn't have it before and the lipstick my mom gave me. It's deep red and makes my lips pop. Obviously the lucky person that gets on these lips is going to have to explain why they look like they sucked a can of beetroot during the party.

I step out of the bathroom and watch Brittany stare at herself in the mirror for a while before noticing me in the doorway. What happens next is completely unprovoked by me, but secretly desired. Brittany's eyes devour me greedily and then she steps forward until she's towering over me. Her hands reach up and grip my arms. She pushes me back against the bathroom door and I gasp loudly right near her mouth.

She looks like she's in a battle with her thoughts, or even her heart. She licks her lips and leans down to brush our noses against each other's. "I'll be 18 next week," I remind her.

She clenches her jaw and closes her eyes. "What if I'm not here next week?" I frown and watch her step back, disappointed at her own actions. "You don't expect me to stay here forever do you?"

"Well I know you have a life to go back to, but I didn't know when exactly you'd be going back."

She nods, mostly to herself and then grabs her purse. "I didn't plan on wanting to stay, I didn't really plan anything."

"It just happened."

"It just happened," she repeats softly. She waits for me to recover and when I do I place some heels on and then grab my purse and keys. I grab Lord Tubbington's kitty litter tray and place it near the wardrobe door. He looks content, all snuggled up against one of his fluffy toys Brittany brought with her.

"Have you got your phone?" She nods and opens the door quietly. I tell her to wait so I can check if my mom is anywhere downstairs. When everything's quiet, I gesture for Brittany to follow. We safely get into my car and don't say a word the entire drive. The tension in the car in unbearable, I wish I could just lean over and give her the tiniest kiss. But that will lead to something more, it always does. Considering how horny we both are from all the teasing today, our control has practically disappeared.

I should have warned Brittany about Puckerman's parties; they always go downhill about half way in. There are drunk people stumbling over empty bottles when we walk inside and half of the squad is slurring 'oh great one' beside me. I send them all a wide fake grin and then pull Brittany through the crowd.

I notice Quinn standing in the kitchen with Sam and I pause for a moment because I didn't even think of how to explain to them what I'm doing here with Brittany.

"Aren't those your friends?" I hear her yell over the music beside me. I bite my bottom lip and nod. "You have to stop doing that."

"What?" I snap my head towards her.

She looks down to my lips and nods. "That, it distracts me." I immediately feel my face heat up and cower away towards the drinks table. Brittany follows, because well, she knows no one here and I hand her a cup of punch without looking at her. I hear her giggle beside me. She's really loving this.

"Santana!" Oh crap.

"Quinn, hey," I say with awkward enthusiasm.

"Not drinking?"

I shake my head and dangle my keys in front of her. "Driving."

"Looks like you need a drink," Brittany mutters beside me. I wince and hope Quinn didn't notice but she's basically skinning Brittany with her eyes.

"And who are you?"

"I'm Brittany," she says happily placing her hand out. Quinn's mouth forms a hesitant smile but she shakes her hand anyway. Sam sends me an awkward tight lipped smile and I send one back. We haven't really been the same since our little hook up a few months ago. Quinn obviously didn't mind receiving my sloppy seconds. She's a trooper.

"You look a little old to be here, no offence," Quinn adds quickly, "are you in college?"

Brittany shakes her head. Oh great she's going to reveal everything. "None taken. I never went to college, I'm actually a porn star." Oh god, she actually is.

Sam's eyes widen and his mouth balloons as if he's going to vomit but he's just trying to contain his laughter. Quinn is even letting out a small chuckle. "And you're here with Santana?"

Brittany shrugs, "yeah."

"Are you going to use Santana in your next video?" Sam asks and I expect Quinn to punch or threaten to rip his lips of but all she does is smirk.

"Well she's gorgeous enough and she's got the body that gives off the impression that she could go for hours," Brittany replies with a hint of mischief in her tone.

"She's just kidding, she's such a kidder," I laugh through the tears threatening to fall and lightly punch Brittany's arm. I look passed Sam and watch Puck half asleep on a sofa with two girls beside him stroking his thighs. I chuckle and gesture for Quinn to look where I am. She scoffs and rolls her eyes.

"He's been like that since before everyone got here," she explains.

"Yeah, I came to drop off a few beers and he was already on his seventh," Sam interrupts. We all laugh and then Quinn tugs on my hand.

"Let's dance!"

I sigh, "you're drunk to I see."

Sam chuckles and Quinn shrugs. "A little."

I look over to Brittany. "Are you going to be okay?"

"Sure," she says firmly.

"I'll be right back." She just nods, which makes me frown because she knows that I would much rather dance with her but I have to satisfy Quinn now and get it out of the way.

Sam says he's going to the backyard to play beer pong and Quinn says she'll meet me on the dance floor. When they leave Brittany and I alone, I look over and notice she's avoiding eye contact with me. I sigh and muster up all the courage I have in me. She releases a small gasp when my lips hit her cheek. I linger for a few seconds and then pull back. She still doesn't look at me, but it doesn't matter because I'm already off to find Quinn.

I notice her amongst some jocks, but they're drunk and shoving each other around so I don't think they'll bother us. Quinn grins when she sees me and grabs my hands. We swing our arms side to side and jump around to the music. We even pull each other close and break out into a waltz. It's sloppy but still somewhat gracious.

"So is that girl the one you're always tweeting?" Quinn says in my ear. I nod timidly and watch a smirk spread across her face. "She seems nice."

"She is," I shoot back instantly.

Quinn chuckles. "So what does she actually do?"

I gulp. "Sh-She already said w-what she did."

"A porn star?" I nod. Quinn laughs again, clutching her stomach and effectively stopping our waltz. "Oh San, you two are hilarious, you belong together."

Brittany's been watching the girls dance for 20 minutes. She hasn't moved from her spot because she's afraid the blonde one Quinn is going to try something. She vaguely remembers that Quinn was making out with that blonde guy she saw before so her breathing relaxes. She just knows what happens when girls get drunk - they start revealing their true feelings and gain more confidence than they can handle.

She thinks that Santana is probably the most responsible person at this party and secretly wishes Santana was drunk so she could see if she acts any differently. Brittany knows not to act on her feelings, she knows it's wrong as well considering Santana is still a minor. But earlier in her room when Santana stepped out of the bathroom in that dress, she couldn't help herself. She's thankful for the little control she had left.

Hearing about Santana's birthday being only days way is too tempting for Brittany to just pack up her things, grab Lord Tubbington and leave. It's not like all Brittany wants is sex. She wishes that was all she wants, but her feelings are a lot more complicated than she expected them to be. Watching Santana smile, dance, even speak is enough to make Brittany's heart race. She thinks she has feelings beyond friendship for Santana and they have yet to even label their relationship as a friendship.

Brittany confirms her own feelings are true, because she's jealous. She's jealous she isn't dancing with Santana, but it's kind of a good thing considering that she's a very flirtatious dancer.

How things ended up so fucked up, Brittany will never know. She's always been careful with her feelings. It's just a job, don't fall in love. She was so preoccupied with that mantra for years, she never thought that someone outside her job could make her feel this way - especially one of her fans.

As her eyes leave Santana for a second, she notices a few guys gawking at her. One of them has their phone out and just before the flash goes off on it, Brittany moves forward out of the suspicious gaze of on lookers and squeezes her way through to Santana. The brunette is facing away from her and she shuffles on her feet awkwardly waiting for her to turn around. She looks a little preoccupied and Brittany can't deny how cute Santana and Quinn's friendship is.

She notices Quinn look over at her and smirk. She then taps Santana's shoulder and points towards Brittany. Santana turns around and her face glows amidst the flashing lights all around them. Quinn excuses herself which goes unnoticed by both girls because they only have eyes for each other right now. Brittany thinks she's falling for the girl in front of her.

Brittany isn't dressed too scandalously, which is a big help to me considering we're moving closer to each other and breaking into a safe slow dance. If we were both in short, tight dresses, I'm positive we wouldn't be dancing this close. But Brittany's wearing tight jeans and a loose tank top with a picture of a pair of lips on the chest.

When the light glides across her face, I can see the lipstick mark I left on her cheek earlier. I also notice for the first time the freckles lightly dusted atop Brittany's nose. The bass is heavy in here, so we don't bother saying anything. While everyone is jumping and fist pumping, I'm holding Brittany in my arms and swaying as though we just entered in a ballroom contest. Her fingertips glide down my back, seducing me into the dance and helping me relax.

I breathe in her scent and memorise the smell. I think it's Chanel, because my mom owns a similar perfume. It belongs on her body, taking refuge on her skin just waiting to be inhaled and adored. There's one characteristic not many people would suspect a porn star would possess; class. Brittany has so much class around new people, give or take a few blunt slip ups. She's even classy in her hold, while she dances. She doesn't use me as a prop, she moves with me - guides me into the next step.

Suddenly Brittany pulls back and without a word, leads me out of the house into the garden. We find a private spot near a swinging chair and sit down on it. No one is paying us attention so Brittany scoots closer to me. "I don't want you to think that I'm waiting until you're 18."

I nod quickly and open my mouth to say I know but she places a finger against my lips. "You mean more to me than I thought you would and it's not about getting you into bed," she takes a deep breath, "it's about spending this time that I have here getting to know you. I'm staying for as long as you want me to stay Santana."

We share a small, shy smile. "I want to get to know you as well, even though I have some knowledge of what your favourite food is and colour and where you like to spend your time in LA..." I trail off, realising how much a of a stalker I sound like.

She laughs, "well now you get to know the real me."

Flash. "What the hell?" I snap my head towards the source of light and notice a few jocks giving each others hi5's. The one with the camera phone runs off and ends up smashing right into the beer pong table.

"Dude what are you doing?" One guy yells. Sam walks over to the guy and shoves him off the table. I notice Quinn walk up to Sam and pull him away before he can get involved further.

Puck comes storming outside, looking a little more sober after his nap and walks straight to the guy who fell. "What's going on bro?"

"Nothing," the guy whimpers from pain.

"You look like shit," Puck and everyone else laughs.

The guy rubs his shirt and then looks over towards Brittany and I. "Did you know there is a porn star at your party Puck?"

Shit. I think on my feet and quickly turn to stand in front of Brittany. I shove us over a little to hide behind a few people still dancing. "Kiss my neck," I whisper.

"What?" Brittany replies in disbelief.

"Just kiss my neck!" I grab Brittany's cheek and pull her head down so her mouth meets my collarbone. She hesitates for about a second before timidly pecking at my neck.

"Over there!" the guy yells and I can feel him pointing over here. I turn us around, Brittany's lips not breaking from my neck. I watch Puck stare over here and he frowns.

"That's just Santana getting her mack on with some hottie," he explains. Thank god. I grin and wave over to him and a few people laugh.

"Ouch," I hiss. I feel Brittany's giggles vibrate against my skin. She just bit me. She's loving this. When the attention is off of us, I go to pull Brittany off me, but she sucks hard against my pulse point. I release an involuntarily moan, which only spurs Brittany on. Her kisses become desperate and I'm afraid if she keeps going I won't be able to control the volume of my moans.

"Let's go," I whisper. She pulls back, her lips parted and her breathing erratic. I chuckle and roll my eyes.

I grab Brittany's hand and luckily the music is over powering enough that it blocks out our foot steps. "There, there!" The guy yells and everyone looks our way but there are too many people for them to know who this guy is talking about.

"You're drunk Karofsky, go home."

We run through the house and end up back at my car. "That was interesting," Brittany says with a devilish grin. I smile back and unlock my car. Once we're both inside everything turns quiet and I don't realise how hard I'm breathing until now. "Where are we going now?"

I bite the inner wall of my mouth. "I guess we could go for a drive."

"Sure," Brittany replies softly, clasping her hands together tightly. I think she's afraid of releasing her hands in case they fly over to me like a magnet. I can't believe she wants me. Holy shit.

We drive off down the street and I decide to just take the long way home. The first turn we take Brittany decides we should play a game.

"Truth or dare?" she says. The first thing that comes into mind is sexual, great.

"Truth," I answer.

"Boring!" Brittany yells in a deep voice.

"Okay okay, fine dare, gosh."

Brittany taps her chin in thought. "Stop the car," I park in front of a random house, "now strip and run down the street."

"What? No!"

"Santana you can't turn down a dare, you have to do it," Brittany explains seriously. "Lord Tubbington once turned down a dare and I hid his cigarettes in the vacuum bag because he's terrified of that thing." My hands grip the steering wheel and I contemplate speeding off home and hiding in my room, but I really want to stay out with Brittany.

"All right," I mumble. I unbuckle my seat belt and step out of the car to undress in the back seat. Once my clothes are off, I count to five and race out of the car. I don't look back as I run down the road. It feels good, feeling the cold air against my bare skin. I pause when I feel I've run enough and notice Brittany drive the car right beside me. I go to open the back door but it won't budge. I look over to Brittany and notice the smirk overtaking her features.

"Oh hells no," I squeal and bang on the window. "Open the door!"

"You look hot I prefer it this way," Brittany replies innocently. I roll my eyes and decide to join in the fun. I press my boobs against the window and shake them.

"Open up!" I hear the click on my car less than two seconds later. I giggle to myself and hop in the back seat.

I shiver as I place my dress back on. "Your t-turn Miss. Pierce, truth or d-d-dare?"

"Are you okay?" Brittany asks with a concerned look. It's adorable.

"I'm f-f-fine, don't ch-change the subj-j-ject." Brittany ignores my plea and parks the car again. She steps out of the car and enters the back seat.

"Come here," she whispers, holding out her arms. I move forward but she gestures for me to turn around so I do. I lean back into her, her lips hitting the shell of my ear.

"I didn't realise how cold it was, I'm sorry," she whispers.

"It's o-okay." I don't think I'm stuttering from the cold anymore. She rubs her hands up my arms and back down again. I tilt my head back, exposing my neck.

"You want me to kiss your neck again?" she whispers chuckling.

I breathe out a laugh through my nose and snuggle further into her. "I don't think I'll be able to handle that again." I feel a buzz under my calf and lift my leg up. I lean up and reach for my purse, taking my phone out of it. It's a message from Quinn.

Noticed u & Brittany left early. Can you come 2 the cafe near my house?

"Are you hungry?" I ask turning back to Brittany. She's memorising my back, running her fingers along each contour visible through my dress.

"A little," she states softly, not taking her eyes off of my back.

"I'm 18 on Tuesday," I remind her once more. Her mouth tilts up into a sad smile.

"Yeah," she breathes and pulls her fingers away. We both step out of the car head into the front seats. I start the engine and silently watch Brittany as she runs her fingers across her lips. I smile to myself, before stepping on the pedal and driving off.

We're sitting at a table with Quinn and Sam in the quaint cafe, listening to them argue back and forth about how bleach Sam uses on his hair. Apparently he was so desperate, he sneaked into Quinn's house when she wasn't there and stole bleach her mom uses.

Quinn's attention focuses on me now and she begins interrogating me about my current relationship status with Brittany because apparently she saw me enjoying the lip attack on my neck.

"I didn't want to get any attention on Brittany," I reply calmly.

"Why?" Quinn asks with a patronizing gaze that pierces into my soul.

"She's new to town and I don't want people to interrogate her, just like you're doing now," I respond threateningly, folding my arms in defiance.

"How did two meet?" Sam asks with a mouthful of muffin.

...Wanky.

"I met her online," Brittany interjects.

"So she is your twitter lover," Quinn says wiggling her eyebrows.

"Twitter lover?" Brittany asks amused. I sink down in my chair now that all eyes are on me. Thankfully not for long because Quinn changes the subject and asks Brittany about her life. I listen to see if she tells the truth, and she does. She doesn't repeat the porn star part because Quinn can think what she wants, but she does mention Lord Tubbington and her life in LA with some interesting people.

"So you wish you were a dancer?"

"A professional dancer, yeah."

"You never told me that," I interject.

"You never asked." Okay now I feel like the biggest bitch on earth. Brittany's wanted to get to know me and all I've done reciprocate her flirting. I guess it isn't fair that she's been flirting with me a whole lot too, but I was making myself out to be this responsible fan and I never even considered asking her general friendly questions.

"So you guys are like doing something illegal here?"

"We haven't done anything," I state firmly.

"Except attack each other's neck," Quinn chuckles and so does Brittany.

I sigh, "I'm 18 next week Quinn, it's not that big of a deal."

"So you're just going to look at each other until then?" Quinn says, before looking over at Sam and slapping his head lightly. He frowns and leans over to her, disregarding his bowl of fries for good.

"No," I roll my eyes, "we're going to get to know each other." Brittany smiles and nods.

"Wow," Quinn gasps, "Santana Lopez actually taking the time to get to know someone?" I send her a warning look. "That's only ever happened with one other person."

"Who?" Brittany asks curiously.

"Me," Quinn says proudly. Brittany laughs and reaches over to pinch my cheeks.

I swat her hand away and shove her playfully out of the booth. "We're going now," I inform them. Quinn pouts but wishes us the best on the next few days of torture. My eyes widen as I hear those words because it hits me that these next few days will be the hardest of my life.

When we arrive back home I don't even consider hiding Brittany and basically sell her to my mom who is standing in the kitchen. She spots us before I can tell Brittany to run and I whimper a little in fear.

"Whose your friend?" I stand frozen, unaware that Brittany is walking right passed me to my mom.

"I'm Brittany, nice to meet you Mrs. Lopez."

My mom's eyes widen in surprise at Brittany's nice manners. "Well it's nice to meet you to dear."

I step forward, "B-Brittany needs a place to stay for a while because of..."

"My parents kicked me out."

My mom and I gasp. "Why dear?"

"I told them I'm gay," Brittany says in a strong voice that I've never heard before.

My mom shakes her head, "stay as long as you need."

I kiss my mom goodnight and take Brittany upstairs. We silently get changed and Brittany decides to wear pyjama's this time. Lord Tubbington is still snuggled against his toy. He's snoring lightly and I giggle before sliding into bed.

"Does Tubbs like the outdoors?"

"He's more of an indoor cat," Brittany replies.

"Oh," I breathe and we both lay in bed silently after that.

Forty five minutes later, Brittany is snuggled against me like she was this morning. She doesn't move though, I'm thankful for that. I'm still very much awake, deciding whether or not to wait until I fall asleep or just talk to Brittany and see if she responds.

"Was it true what you told my mom?"

There's a beat before she answers. "I was 16." My hand automatically falls to her thigh that's draped over my legs. I don't move my fingers, my hand kind of just lays there on her skin.

"They kicked you out when you were 16?" I ask in disbelief. Brittany nods against my shoulder.

"They were religious, we attended church every week. When I told them they said either get out or they would put me in one of those camps where those adults try and make you better and convince you your homosexuality is a disease."

"Where did you go?"

"I stayed with friends, they were more accepting. A year after they kicked me out I got sent a letter, saying that my parents had passed away and they left me some money. I'm surprised they didn't rip that will up or change my name to a heterosexual family member. It was enough to last me four years. When I was beginning to run out, I went to a few major dance companies and they wanted a person with more experience. So I settled for having sex in front of a camera for money. This guy found me at strip club because I used my last $70 on a lap dance. That night my life changed," she yawns.

"I'm glad you found your way to me and I'm sorry about your parents."

"Me too," Brittany responds tiredly. When everything becomes quiet again, I begin moving my fingers along her thigh, tickling her but not enough to make her start laughing.

"What are you doing?" She whispers. My hand freezes.

I gulp. "I don't know." She doesn't respond so I keep talking. "Do you want me to stop?" I wait about a minute for her response which eventually doesn't come in the form of words. Instead she tilts her head up and places a kiss against my jaw.

"No."

My lids fall shut as I lean into her touch. "Well then I don't want you to stop," I reply, moistening my lips when they become really dry. Brittany sighs and tilts her head back again so her lips are near my ear.

"Santana we shouldn't do this," she breathes.

"We're not doing anything wrong," I whimper, trying to convince myself as much as Brittany.

I hear her breathing start to relax and her stomach rubs against mine gently when she shifts. "Your heart is beating really fast."

"Sorry," I breathe out.

"Don't, just relax."

I close my eyes and inhale deeply. When I exhale it comes out shaky so I do it a few times until my breathing becomes smooth. My eyes flicker to Brittany to see if she's moving but she doesn't. I think she fell asleep.

Just when I'm about to fall asleep, I feel a light pressure applied to my jaw, again and again. Small pecks become open mouth kisses and eventually she's gently sucking on my pulse point. I bite my bottom lip and my grip on her thigh tightens. She presses her centre into me, just once. She releases a shaky breath and presses her forehead against my shoulder.

"I think I just came from kissing your neck." Holy shit. I pinch my thighs together and clench my fists so my fingers aren't able to move on their own accord.

"I want to taste it, I want to taste you," I reply shakily.

"Santana..." She exhales.

"Please Brittany." I feel her arm move. I lift my head up the slightest bit and watch Brittany's hand enter beneath her shorts and underwear. After a moment or two she brings her hand up to her lips and kisses her fingertips. Then her fingers are near my mouth and I gently suck them between my lips. Holy shit.

My tongue pokes out to slide up her fingertips and I reluctantly let her fingers slowly slip from my lips. "You taste so fucking good."

"Better than ice cream?" She teases.

"Better than ice cream," I confirm. We lay in silence for a while as I try to recover from what just occurred. I don't know what to think anymore, all that occupied my mind, before she even showed up, was Brittany. She's still all that occupies my mind and now she's here and I never want to let her go.

"Goodnight," I whisper.

She presses one last light kiss to my collarbone. "Goodnight."
