Summary: Brittany thinks they should go to the Glee Club's Christmas Eve party but grumpy Santana just wants to do Christmas in bed with her girlfriend instead. When Santana turns up the charm, the coy blonde can't resist her lover's seductive side.

A/N: Hope you guys like this!

I've always wished we could hear Brittana singing this as it would have been such an adorable duet for them.

This is set sometime during S3E09 Extraordinary Merry Christmas. Let me know what you think xoxo

Santana had never been a big fan of Christmas but now that she was dating Brittany, she got swept up in the fun of it almost as much as her Christmas elf girlfriend. Brittany playfully chided her for taking bites out of the snowman-shaped cookies that had been freshly baked and placed on the Pierce family's kitchen table to cool while Lord Tubbington watched the two bakers with baleful eyes from the corner.

"Santana! You know those are for Santa."

"Sorry. I'm sure old fatso has had more than enough of these to last him a lifetime. Besides, I can't help it - your cookies are so tasty, Britt." Santana smirked, kissing Brittany on the cheek as she sneakily got behind her, wrapping her arms around the blonde's waist. Brittany smiled, dipping her head bashfully.

"Mmm, all thanks to someone's help," Brittany turned around in Santana's embrace to face her, adjusting the Santa hat she had placed on the darker girl's head. "Such a flatterer. I can't resist you when you're dressed like this."

Santana raised an eyebrow, as she never knew what to make of her girlfriend's odd attraction to her in a Mrs. Claus outfit but she didn't complain one bit because it got her plenty of sweet kisses and more. Their lips met and Brittany smiled into the kiss, which made Santana smile as well.

"You taste so good. Delicious."

"And you look so good in that apron..." Santana flirted, pulling Brittany closer by her hips as her voice dropped low and husky while she leaned in for another kiss. "I think it would look even better on your bedroom floor."

At that moment they were interrupted by Whitney and Pierce Pierce loudly moving into the kitchen, smirking when they saw the position the two were in. Santana's face turned a deep shade of red and Brittany giggled, her own face flushed as she pulled away from the kiss but remained in the embrace, not taking Santana's hands off of her.

It wasn't like it was anything new to the Pierces that Brittany was dating Santana now and they had walked in on the two girls so many times that Santana could barely look Whitney in the eye. There was no way to really erase the embarrassment of your girlfriend's parents catching you getting frisky with their little girl on the living room couch.

"Oh my! I hope we're not interrupting anything," Whitney chuckled, putting on her coat. "You two are just so cute. Dad and I are going out, since well... someone forgot it's Christmas and we have some last minute shopping to do. We trust you to hold down the fort when we're gone."

"Sure, Mom. You got it." Santana grinned at how breathless Brittany sounded when she answered her mother. Whitney winked at them.

"Have fun... but not too much fun!" The older blonde woman yelled as she grabbed a confused looking Pierce's arm and pulled him out to her car in the driveway. "We're not ready for grandkids just yet."

"Where were we?" Santana husked into Brittany's ear seductively when the parents had driven off finally. Brittany shivered at the hot breaths against her neck but tried to resist the temptation, putting her finger against Santana's full lips.

"Uh uh, Babe... not just yet. We still have presents to wrap."

"Hmm there's something else I'd like to unwrap instead..."

"Santana!" Brittany giggled, slapping her on the arm lightly. She moved away before she could give in to the temptation of kissing that dimpled, sexy smirk off of Santana's face. Her girlfriend was irresistible. She went over to put back some decorations on the tree that Lord Tubbington had knocked off for the hundredth time that morning.

"San - Sandtana, can you help me with my snowman?" Tiffany, Brittany's six year-old little sister chose that moment to run into the kitchen from the front yard and Santana jumped away from her girlfriend who she was in the middle of kissing. "Ew you guys aren't allowed to kiss on the lips!"

Brittany and Santana laughed at the little blonde girl's offended face and the way she still couldn't pronounce the dark-haired girl's name. Santana inwardly groaned but she couldn't very well deny her girl's cute little sister anything she wanted.

"Sure, Princess. We'll build the best snowman ever."

"Let her breathe, Tiff." Brittany giggled, shaking her head as the already tall girl tugged on Santana sleeve, pulling her at full speed into the Pierce's yard and sticking out her tongue at her big sister. Of course, that meant both Pierce girls and Santana spent what felt like a million years having a snowball fight when Tiffany had finished her snowman, the three of them laughing the entire time.

After they finished, they went inside for hot chocolate made by Brittany and the freckled blonde surprised Santana by grabbing the collar of her shirt, pulling her in close and kissing her softly. She pulled away after a few seconds, catching a confused Santana's eye.

"You're kissing?!" Tiffany shouted, scandalized but giggling.

"It's mistletoe. We have to." Brittany laughed, pointing at it overhead.

Santana didn't get to enjoy the Christmas gift she actually wanted - getting Brittany in bed for some alone time - as the blonde kept her busy with cooking up a storm and asking her for help with putting up some more lights outside the Pierce's house. Of course, Santana never refused but it made her a little grumpy that she didn't get any further than making out with the blonde while her parents were out. Tiffany being around only made it even more difficult to get up to any hanky panky with the hot blonde as they had to keep it G-rated.

"This is the best Christmas I've ever had. A million times better than the last one," Santana admitted as they sat around drinking some wine later in Brittany's bedroom after dinner with the Pierces. She was lazily lying on her back on Brittany's bed while the blonde sat perched on the edge. Her expression darkened as she thought of the depressing previous year when part of her thought she had lost the blonde for good. "You and Artie..."

"Oh, Santana. That could never even compare to us," Brittany kissed her reassuringly, climbing onto Santana's lap and leaning over her. "You know I always loved you the most."

"Me too. What do you say we make this Christmas even more special, Beautiful?" Santana's smile turned lustful, raising her eyebrows as she looked over Brittany's body. The blonde knew exactly what she was thinking and rolled her eyes with a giggle when the darker girl put her hands on her waist. Brittany heard the robotic meow tone that told her someone sent her a new text and pulled away from Santana, reaching over to pick up her pink flip phone that was on her bedside table.

"Who's that?"

"Huh. The Glee Club invited us to their party tonight." Brittany said, reading the texts on her phone that were suddenly coming in. Santana's mood darkened and she made a sound of annoyance, shaking her head. It was already seven and the last thing she wanted to do was go back out. Besides, there was something way better she could be doing.

"Kind of late notice and it's not as if I want to spend my Christmas Eve with those tone deaf losers," Santana muttered grumpily, crossing her arms behind her head as she lay back against Brittany's pillow. "Don't any of them have a life outside of Glee Club?"

"I don't know San... maybe we should go. Mr. Schue is going and Rachel's going to be singing."

"Fuck Schue and Rachel! Who the hell cares about them? They can all go get stuffed up a chimney for all I care."

The blonde couldn't stop laughing at how infuriated her girlfriend was.

"What? I want you alone okay. We have plans." Santana insisted, nipping Brittany's ear and toying with the waistband of her tight jeans when the blonde moved closer.

"Oh really? What plans are those?" Brittany acted coy, batting her eyelashes.

"Plans for you and me, Babe. You know you want it."

"I don't know if we can do that... my parents and sister are just down the hall. Not to mention, what would Santa Claus think if he saw?"

"What? Britt, they're not gonna know. To hell with the dumbass Glee Club and everyone else."

Brittany smiled at Santana's annoyance at the others. She knew how much Santana had been looking forward to getting her in the bedroom all day and teased her by singing a familiar tune.

I really can't stay

Santana's lips curved upward at the sound of Brittany's cute, clear and sweet voice. She joined in smoothly with her raspy, smoky voice and they went back and forth.

But, baby, it's cold outside

I've got to go away

But, baby, it's cold outside

Brittany smirked coyly as Santana played along, singing in a low voice and practically chasing her around the bedroom whenever the blonde teasingly skipped away. It was all a pretense on Brittany's part as the blonde had no real intention of leaving, nor was she as innocent as she was acting and they both knew it.

This evening has been (Been hoping that you'd drop in)

So very nice (I'll hold your hands, they're just like ice)

My mother will start to worry (Beautiful, what's your hurry?)

Brittany sat down on the bed and Santana slid in next to her, slipping an arm around her shoulders with a lustful look in her eyes. Brittany pretended to play hard to get, slipping away from the Latina yet again and going over to put on her jacket. Santana pouted when the blonde moved the Latina's hand off of her ass and pulled away with an innocent smile.

My father will be pacing the floor (Listen to the fireplace roar)

So, really, I'd better scurry (Beautiful, please don't hurry)

But maybe just a half a drink more (Put some records on while I pour)

The neighbors might think (Baby, it's bad out there)

Say, what's in this drink? (No cab's to be had out there)

Brittany didn't know how Santana managed it but before she knew it, her pink ugly sweater had been pulled off and the Latina got her back into bed, crawling up to kiss her. Brittany playfully put her hand on her face, pushing her away and Santana laughed as she lost her balance, falling off of the bed. She recovered from that and smoothly took Brittany into her arms, the tension increasing between them as their eyes drifted to each other's lips. Brittany thought there was nothing sexier than the way Santana was trying to seduce her and singing in her low, smooth voice.

I wish I knew how (Your eyes are like starlight now)

To break this spell (I'll take your hat, your hair looks swell)

I ought to say, "No, no, no, sir" (Mind if I move in closer?)

At least I'm gonna say that I tried (What's the sense of hurtin' my pride?)

I really can't stay (Oh, baby, don't hold out)

Baby, it's cold outside

Brittany gave her a quick peck on the lips and Santana grinned, obviously thinking she had "won" their game but then Brittany danced away once again, making it clear that the song wasn't over. Santana was confused but followed along.

I simply must go (But, baby, it's cold outside)

The answer is no (But, baby, it's cold outside)

Your welcome has been (How lucky that you dropped in)

So nice and warm (Look out the window at the storm)

My sister will be suspicious (Gosh your lips look delicious)

My brother will be there at the door (Waves upon the tropical shore)

Brittany loved how persistent Santana was being and ever time the Latina came near her with those intense, almost black eyes filled with consumed lust or caressed her skin, the taller girl would shiver as she found it increasingly difficult not to give in to temptation. Santana smirked mischievously, knowing the effect her actions had on the girl.

You've really been grand (I thrill when you touch my hand)

But don't you see? (How can you do this thing to me?)

There's bound to be talk tomorrow (Think of my lifelong sorrow)

At least there will be plenty implied (If you got pneumonia and died)

I really can't stay (Get over that cold out)

Baby, it's cold

Baby, it's cold outside

They sang the last part together perfectly, their voices harmonizing sweetly and by the time they were done they were both breathless. Santana kissed Brittany long and hard when she finally got the taller girl into bed after that, chasing any thoughts of the Glee Club, little sisters, candy canes, elves, sugar plums, Santa and anything else that could distract her from her head. Santana got both of their clothes off so fast that Brittany wondered whether she had some kind of super power.

"You like?" Brittany smirked, noticing the way Santana froze and stared at her body with interest with those ever so dark, lustful eyes when she noticed the new lacy, red lingerie she was wearing that she had never seen before. Apparently Brittany had been planning this all along as well, the little tease. "Merry Christmas, Babe. It's all for you."

The Latina glanced at Brittany's bedroom door, making sure it was locked before stripping the lacy, silk fabric of the thong away, moving her hand and showing her girl exactly how much she appreciated her Christmas gift.

"Oh, oh, oh, Santana!"

"Shh, Sweetheart." Santana chuckled against her skin, kissing her cheek as Brittany had to muffle her moans against her pillow, a pink flush working its way up her chest to stain her pale, cheeks prettily.

The blonde rested her head against Santana's chest a few steamy love making sessions later as both of them were sweaty and sated. She closed her eyes, tracing a heart on Santana's skin and smiled against her, feeling warm and cozy nestled against her girlfriend as the snow continued to fall heavily outside.
