Author's note: Okay. Just to clarify a bit: as of right now, this story is only a slight crossover with Grey's Anatomy. Everything takes place in the Gleeverse and any Grey's Anatomy character is just simply mentioned. Really, it's just only Callie's character. Later on, her character may become more important and will play a bigger role, but I'm thinking that I want this story to just really be Santana-centric. If you aren't familiar with Callie's character/Grey's in general, just tell me and I can give you a recap of Callie's story line in concision to this story.

There's a reason why I titled the story Glitter in the Air.

(Also: I don't want to beg for them, but I like reviews, too.)

"How are you not cold?" Santana asked, tightening her jacket that said Junior Cheerios on the back around herself.

Brittany shrugged. "I thought the long socks would help." She was wearing a pair of shorts with striped socks that reached her knees and her own Junior Cheerios jacket hanging loosely around her arms.

"You should know better, Britt. It's February."

"I don't know how to read calenders."

Santana rolled her eyes. "C'mon, we're almost at my house, anyway." She took off at a jog.

Brittany caught up to her, saying, "Your neighborhood is scary,"

"Only at night," Santana said. "Besides, you're with me."

"Are you my protector? Like a knight in one of those fairy tales?" Brittany asked, holding on to the straps of her backpack.

Santana slowed down her jog, having reached her driveway, and cracked a smile. "Somethin' like that."

They walked up the steps into Santana's house, leaving their shoes, jackets, and backpacks by the front door. The house was warm and the kitchen radio was blaring some classic rock station.

"It's so cozy in here," Brittany said, sliding her feet along the wooden floor. "Is there someone home?"

"My mom doesn't have classes on Friday," Santana explained, walking into the kitchen only to find it empty.

"Ooh! Does that mean she can drive us to the basketball game later?"

"I hope so. Puckerman's suppose to be there." Santana smirked.

Brittany giggled.

Santana frowned and called out for her mother. "Mami!"

There was no response and she rolled her eyes. "Mami! Britt and I are home!"

Brittany leaned against the stove, continuing to slide her feet across the floor. She looked up when she heard footsteps coming down the staircase and said to Santana, "I think she was just upstairs."

"¿Qué estaba pensando? Y en Las Vegas de todos los lugares!"

"Crap," Santana said, inching closer to the edge of the kitchen. "She's using Spanish."

The footsteps got louder as Mrs. Lopez bounded down the stairs, and with one final Spanish-infused comment, she hung up the phone and walking straight into where Santana was standing.

"Oh! Sorry, mija. I didn't see you there." She side-stepped her daughter and set the phone down on the kitchen table. "Hello, Brittany," she added upon seeing her daughter's friend. She pulled out a chair and was about to sit down when a thought hit her. "You're spending the night, right? While you're parents are at that convention in Cleveland?"

"Mmhmm!" Brittany smiled widely; she always liked Santana's mother and she always liked spending the night at Santana's house.

"You were speaking Spanish." Santana deadpanned, crossing her arms.

Mrs. Lopez sighed. There was no point in lying to her daughter. "I was on the phone with your abuela."

"Is everything okay?"

"Your aunt got married."

Santana quirked an eyebrow. "Tia Callie? Why is that a bad thing?"

"She eloped in Las Vegas with some intern that work at the hospital with her." Mrs. Lopez explained, shaking her head.

Santana scrunched her face and exchanged a glance with Brittany. The word "intern" made the guy sound overly young and creepy. "When's papi coming home?"

Mrs. Lopez sighed again. "Oh, not until late."

Santana frowned and Brittany pushed off of the counter and walked up next to her. Brittany shuffled her feet and Santana nudged her.

"Do you think you could drive us to the basketball game later?"

"I'm sorry, mija, but now is just not a good time." She looked at the clock on the oven and said, "I have to call your father; he should be out of surgery now." Mrs. Lopez picked up the phone again and Santana took Brittany's hand, turning around and dragging her upstairs.

Santana flopped down on her bed with a huff and Brittany flopped down right next to her. The blustery February skies casted a greyish-blueish tinge into Santana's room and all across her stark white walls. Brittany shivered, the thin material of her long-sleeved shirt not being enough to protect her against the cool air coming from the windows.

"San, can we get under the covers?"

Santana looked over at her friend, who was gripping tightly at her arms and biting her bottom lip.

"Sure," Santana lifted up her pillow and pushed down the sheet and quilt so Brittany could crawl in. She grabbed the feather comforter from the other end of the bed and pulled it up. She slid in next to Brittany, laying on her back with her arms crossed.

"Are you mad about not being able to go to the game?" Brittany asked, ever the obvious. She was curled up underneath the blankets with the comforter up all the way to her nose.

"Yeah," Santana said, uncrossing her arms. "Plus I'm a little upset about my tia."

"Why? Isn't it good that she got married? I don't know what the ear lobe had anything to do with it, though..."

Santana turned onto her side to face the blonde. "Elope, Britt. It means that she and the guy got married super quickly without telling anyone."

"Oh," Brittany thought for a moment, adjusting the comforter so she could breathe easier. "I think that would be fun. To just run off and get married."

"But then you wouldn't get to wear the white dress or have people cry over your happiness," Santana pointed out.

"That's true," Brittany agreed. "I want ducks to walk down my aisle!"

"Ducks?"

"Uh-huh! I think it'd be super cute to have little yellow duckies walking and quacking along with me."

Santana rolled her eyes. "I don't think any guy would let you have ducks at their wedding."

"I'll marry a girl, then."

"Ew, Britt. You can't do that. It's like, illegal, or something."

"It is?" Brittany furrowed her brow.

"Duh."

"Oh." Brittany licked her lips and tightened her grip on the blankets. "How come your tia eloped? Didn't she want to wear the white dress and have people cry over her happiness?"

"I don't know," Santana replied, brushing a loose strand of hair out of her eyes. "I like, never see her because she's so far way."

"Do you get to talk to her at all?"

"Sometimes. I wanted her to come and visit for my birthday 'cause I haven't seen her since I was seven, and turning thirteen is like, a huge deal."

Brittany tried shrugging but her cocoon of blankets was too tight. "Not really."

Santana shot up, accidentally tugging the comforter and quilt away from Brittany. "What? Britt, that's ridiculous. How can being thirteen not be awesome? You're like, a teenager now. You can practically do whatever you want."

"I still have to do all my chores and homework and stuff, and it's not like I look any different."

"Yeah, but you can do so many more things, like get your ears pierced at the mall without having your parents there, and see PG-13 movies, and you can probably even get past first base with boys."

"I already have my ears pierced, San, and we saw that movie last week without any grownups with us. Besides, I turned thirteen last month, remember? And I still haven't kissed a boy."

"What? Really?" Santana sat with her mouth slightly agape. "But you went to the winter dance with Matt Rutherford!"

"Yeah, and he didn't kiss me, and I wasn't gonna' kiss him first." Brittany sat up too, leaning against her elbow.

"So you've never kissed a boy before?"

Brittany shook her head. "I don't think I even know how to do it. Have you and Puck kissed?"

Santana's face flushed. "A few times. But, to be kinda' honest, I didn't really know what I was doing at first. He just sorta' smashed his lips into mine."

"I thought kiss was supposed to be fun and romantic," Brittany said. "It is in all the movies."

"I think you just need to practice and get good at it."

Brittany hesitated for a moment. She looked up at her best friend and pushed up from her elbow. "Do you think you could teach me?"

Santana's mouth felt dry. Brittany wanted to kiss her? "W-what?"

"Can you teach me? How to kiss?"

"Britt...we can't do that. We're both girls."

"But you're just teaching me, right? If it's just for practice, it doesn't have to count."

A heavy wind pounded against the windows; Lima was supposed to be getting snow later that night. Santana fidgeted with the tag on her green pillowcase, trying to avoid the blonde's gaze. After almost a minute of awkwardness, she gave up with a sigh, and looked down at her friend. Brittany's eyes were earnest and a shade of blue deeper than what Santana had ever seen before.

"Okay," she whispered.

Brittany smiled, but then a nervousness crept up on her, seeping from her face to her chest to the pit of her stomach. What if she was bad at kissing? What if Santana freaked out and decided that she didn't want to be her friend any more?

Another gust of wind hit the window and Santana leaned in, brushing her lips against Brittany's. As quickly as it had started, it ended, and Brittany wasn't sure if she had done it right. Santana pulled back, her tan face tinged with a red blush.

"Um, that was..."

"Bad," Brittany provided. "I don't think I'm very good."

Santana didn't say anything.

"Can we try again?" Brittany was determined to get this kissing thing down, and she really wanted Santana to help her.

Santana licked her lips; they tasted faintly like the melon LipSmackers that Brittany normally used. Another silent beat passed and she nodded.

It took two more awkward attempts until they both got it right; Brittany had tried to mimic Santana's move by leaning in, too, and almost forgot what to do with her mouth. By the fourth try, she knew not to keep her lips tight and pursed, and when Santana's lips hit hers, a warmth spread through their bodies greater than any quilt or comforter could do.

Santana closed her eyes. Kissing Brittany felt different than the times she had kissed Noah Puckerman. His lips were always chapped and he slobbered them up with spit to try and make up for it. Brittany always carried around LipSmackers and she was much softer and gentler than Puck. The warmth that spread through her from kissing Brittany made her want to get closer to the blonde, to wrap her arms around her like on television shows.

The thought scared Santana and she snapped her eyes back open, pulling back.

"Was...that better?"

Santana looked back at Brittany, her eyes still that same, deep blue. "You're a natural, Britt."

Brittany smiled again, all of her nervousness gone. "Thanks, San." She reach her arms out and enveloped Santana into a hug.

Santana returned the embrace, her face still numb and hot and her heart thudding so loud that she was surprised Brittany couldn't hear it.

"Mija!"

The two girls let go of each other and Santana slid off of the bed, her knees shaking as she walked over to the door and opened it.

"Yes?"

"I'm ordering a pizza. What do you girls want on it?"

"Oh, oh! Banana peppers and pineapple!" Brittany squealed.

Santana faked a gag and stuck out her tongue. "I get the peppers, but not the pineapple."

Brittany pouted. "I guess we can just get the peppers, then."

Santana ignored the pout and nodded. "Banana peppers," she called down to her mother.

"Do you guys want to watch a movie, too?"

Tired of having to shout down, Santana walked out of the bedroom and to the first floor landing; she could still feel her heart thumping loudly. "Hm?"

"Movie. Do you guys want to watch one when the pizza gets here?"

Brittany would want something Disney, Santana thought to herself. In exchange for the lack of pineapple on the pizza, Santana conceded with what she knew the blonde would enjoy. "Something Disney."

Her mother gave her an apprehensive look.

"What?" Santana shrugged.

Her mother said nothing and shook her head with a tiny smile.

"Is everything okay with Tia Callie?"

The smile went away and her mother stopped in her tracks. "Don't worry about that. Just enjoy your sleepover with Brittany."

Santana scoffed. "Please, Mami. Britt's here all of the time. It's nothing special."

The image of kissing Brittany still engraved in her head and the pounding still in her chest would have said otherwise.
