This was suggested to me by gleeeeeeeek89 a couple of days ago, and given this was perfect procrastination material, I thought I'd give it a go. I won't tell you the whole prompt, as it will spoil it for anyone who isn't gleeeeeeeek89 :D

As ever, I don't own Glee, and this is a gp story, if you don't like, I wouldn't read any further.

I hope you like this, reviews, as ever, would be amazingly appreciated! :D

Lima: 2008:

Sex.

It's all Santana can think about.

That and how pretty Brittany looks.

Or how nice her new perfume smells (she smiled at Santana when she complimented her on it and whispered that it was a woman's perfume coming in a glass bottle and costing more than $10).

Or how the sun catches her hair or the freckles that are still dusted over her cheeks and nose, a gentle reminder of summer.

Unfortunately, this often leads back to sex.

Which leads to Santana, shifting uncomfortably in her chair in the suddenly boiling room, trying to pull the material at the crotch of her jeans away from the increasing hardness and muttering about dying kittens, bubonic plague pustules and hairy men's backs under her breath.

Unfortunately, Brittany will often turn around, just when Santana can breathe easily again, and flash her a soft smile that will instantly cause the room to heat up once again.

This had been going on for months, but Santana couldn't bring herself to ask Brittany out. She was worried that Brittany would say no.

Or that she would not only say no, but then tell everyone that Santana had even asked.

Or that she would say yes, but Santana would fuck it up.

Or that she would say yes out of obligation and realise she could do so much better than her.

Someone who wasn't a freak.

The sound of the bell jarred her teeth and she jumped slightly in her seat, her heart missing a beat when Brittany skipped over and leant over the table towards her, tank top dipping slightly causing Santana's throat to dry and her tongue to drag across her lips.

"Ready Sanny?" Santana forced her eyes to lift upwards and lock with blue eyes, slightly darker than usual, before she nodded and smiled. "Awesome. I asked mum to get some munchies in, and I rented some snuggle worthy movies yesterday. Sound good?" Santana's throat was still dry, and so she nodded once again before Brittany was haphazardly shoving Santana's books into her bag and dragging her out of the classroom.

"…he then, he said that my arse and rack were passable enough for him, and did I want to see his dad's new car." Brittany's voice was incredulous, and her nose wrinkled in disgust.

'Fucking adorable' Santana thought, smiling softly at Brittany who was laid out next to her, their feet bumping occasionally and their arms tangled. "I hope you told him to fuck off B."

Brittany snorted and pushed gently at Santana's side. "No, Sanny, I didn't. That would have been rude." Santana shrugged laughing softly. Brittany smiled and turned on her side, hand hovering by Santana's cheek. "I told him that," She swallowed audibly and licked her lips nervously. "That I have someone better."

Santana's head snapped to the side, a frown beginning to form, Brittany hadn't told her she was dated someone, or even that she liked someone, and Brittany told her everything, even the things she didn't want to know, like when she gave Puck a hand job at a party when they were both tipsy and Brittany was curious as to what it would feel like. Brittany smiled wide before pressing her palm to Santana's cheek and bringing their lips together.

It was Santana's first kiss.

That, and her shock, caused her let Brittany lead completely, leaning into the touch of her palm and soaking up the sense of Brittany that surrounded her.

Brittany, with her soft lips, just the right amount of wetness to slip gently over Santana's and her slightly calloused thumb (from years of bike riding, motocross, holding onto ballet Barres and gymnastics) brushing along Santana's cheekbone.

A moan seeped into the room, and Santana's eyes snapped open before she pushed Brittany away, her chest heaving, breaths coming out ragged and loud and she covered her crotch protectively with her hands. They were both in pyjamas and so the bulge that had formed between her legs would be immediately obvious even if Brittany didn't instantly look downwards and smirk slightly.

"What –" Santana took a gasp of air before running her hands through her hair, instantly moving them back down again when Brittany's smirk widened as she licked her lips. "What was that Britt? I mean…what was that?"

A flash a hurt flickered through Brittany's eyes, her smirk falling, before she regained her previous confidence. "I see the way you look at me, and I hear you sometimes when we watch a movie and you mutter really gross things under your breath while hugging a pillow against yourself. And sometimes I can…well, I can feel it." Brittany's eyes fell to Santana's crotch once again for emphasis and Santana felt her face flood with heat, her eyes darting anywhere in the room but Brittany. "I don't mind Sanny." Brittany moved to cup Santana's cheek, but she moved away, until Brittany gripped her chin and forced Santana to look at her. "I kinda like it." Brittany's voice was quiet and innocent, and Santana frowned in confusion. "It's always nice to know that the person you like, likes you back in the same way." Santana's eyes widened in disbelief and she smiled softly.

"You like me?" Brittany nodded. "As more than a friend?" Brittany nodded again. "Really?" Brittany rolled her eyes and nodded again.

"Do I need to say it again?"

Santana laughed and shook her head, before removing her hands (luckily in her panic, she was no longer hard. Well, not hard enough to be noticed anyway) and pulled herself back next to Brittany. "So, um, do you, maybe want to, well, go out with me sometime? Like a date?" Brittany laughed loudly at the hesitancy in Santana's voice before kissing her gently on the cheek.

"I would love that Sanny."

Lima: 1994-1999:

Santana Carla Lopez was born, Santiago Carlos Lopez. He was born three weeks early, but strong and as active as any other new born. His parents were loving, if a little distant and adverse to obvious physical affection, and he spent his first year only in their company.

Then one morning, Mrs Lopez heard a knock on the door, and upon opening it was met with a tall, slim blonde holding a wriggling, smiling blonde baby girl.

"Hi! I'm Annie Pierce, our husbands work together, and Tom, my husband, mentioned you had a little boy around about my Brittany's age. I thought maybe they could have a play date? And we could get to know each other?" Mrs Lopez liked her insulated family, she was close with all her siblings and her parents, but Annie Pierce's smile was so wide and infectious, she couldn't help but smile slightly back.

"Sofia Lopez." Her smile only widened when Brittany's small gurgling's and inquisitive grabbing's intensified, and she heard a small 'oaf' as Santiago had tried to reach out for Brittany, but failed. "And this," She picked him off the floor. "Is my little Santi." Santiago's eyes were wide, and he reached out for Brittany again, who had suddenly settled, content to tip her head and press her hands together, smile wide as ever. "Santiago, after his grandfather. Please come in." Annie nodded and walked through the doorway, waiting for Sofia to lead the way. Sofia pointed towards the front room where Annie set Brittany on the floor next to the small pile of toys, while Sofia placed Santiago on the floor by the front door, watching him quickly shuffle over to Brittany. The two babies sat and looked at each for several seconds before Brittany picked up the closest toy and held it out to Santiago, smiling softly when he took it, and passed it back to her.

"Aw love at first sight." Annie cooed watching the two interact and clasped her hands softly. Sofia smiled gently and nodded.

From that day, Annie would come around every day, sometimes staying and watching the two interact, sometimes leaving them in the play pen and sitting in the kitchen with Sofia, and Brittany and Santiago were inseparable. They started Pre-School together, where they were instantly popular and soon had a large group of female friends, but none were as close or important as the other.

Sofia and Carlos Lopez, however, were uncomfortable with this. They wanted Santiago to have male friends too, they worried if all of his friends were girls, and therefore all the games and toys he played were girl's games, he would be constantly bullied. Their concern only increased when Santiago and Brittany progressed to kindergarten, where once again, Santiago only had female friends.

It didn't help, either, that Santiago had more feminine features that were obvious even in the young four year old boys face. Sofia brought this concern up with Annie, whose talks had progressed to after work when they had collected the children from kindergarten. Annie just placed her hand gently over Sofia's and smiled gently.

"All that means, is that he will grow up to be one of those extremely handsome men that all the girls go crazy for." Sofia looked over to where Brittany was dressing Santiago in a pink scarf, that she assumed was supposed to be a tie, and pulling him over to Brittany's plastic kitchen, and sighed.

The Lopez's fears were cemented when Santiago was five years old.

He and Brittany were playing with a group of girls when three boys from the year above sauntered over. From what the adults could gather, through Brittany's tears and the older boy's denials, they had started calling Santiago names and pushed him and Brittany had retaliated by punching one of them on the nose (even at five, she was tall). When the boy realised he had been punched, not only by a five year old, but by a five year old girl no less, he went to punch her back. But Santiago had pushed Brittany out of the way, taking the punch on the side of his head and causing his body to slump onto the metal slide, slicing his head open and creating a large gash along his arm. Santiago (and Brittany who refused to let go of his hand) were rushed to the hospital and into surgery before anything worse could happen.

By the time Mr and Mrs Lopez (who worked at the neighbouring hospital) had hurried into the waiting room, Annie Pierce, with a whimpering Brittany in her lap, explained that Santiago had been in surgery for an hour. Although the medics in them knew that that wasn't very long, and time didn't indicate severity of the injury, the parents in them were panicking, every possible worst case scenario running through their heads. And so, when the surgeon pushed through the double doors, another hour later and an unreadable expression on her face, they gripped one another's hands and prepared themselves for the worst.

"Dr Lopez's?" Her voice was calm and soft, but reserved. "I've been working on your son, I wonder if you wouldn't mind accompanying me somewhere a little more private?" Annie smiled encouragingly before she squeezed Sofia's shoulder, and the Lopez's followed the surgeon through the doors into a small office. "First of all, Santiago is going to be fine. Cuts and bruises, a few stiches and a broken finger where he pushed his friend out of the way and then fell awkwardly on it. But he is going to be fine." Both parents let out a long breath that weren't aware they were holding.

"So, if he is going to be fine, why are you talking to us here?" Carlos' voice was calmer now, but the underlying fear was still noticeable to the two women in the room.

The surgeon took a deep breath and opened the file on the table. "Well, he lost a lot of blood, and he needed a transfusion during surgery. As I'm sure you are both aware, we type and cross, and well, there were some anomalies with the results. When Santiago was stable, I had the results double checked. The answer was the same." She turned the file around so that they could see the print out for themselves. "As you can see, although Santiago's reproductive system shows the expected XY chromosome in all those cells, all the rest of Santiago's somatic cells, show XX chromosomes." The Lopez's looked at the surgeon with wide eyes. "Santiago, except for his gonads, is a girl. It explains the feminine features, and I was told he got hurt partly because of his preference for playing with girls?" The surgeon paused, waiting for the two doctors in front of her to confirm. "Well, that could also be explained by this, and perhaps, Santiago's knowledge and feeling that he is more of a girl than a boy." The parents were mute. They didn't know what to think or what to do and they gripped tightly to one another. "I know it's a lot to take in. But, given everything the genetic tests show us, and what I've been told by my nurse, who spoke to both children, I would recommend raising Santiago as a girl." Sofia nodded slowly. "Especially as there is a very high chance, that when Santiago reaches puberty, Santiago's voice will not break and will form breasts, something that will be harder to hide as a boy than a penis as a girl." The room fell silent as both parents tried to take in everything they had just been told. "I'm going to let you think this over, stay here as long as you wish, and I'm here for any questions you will have. I also have the genetic specialist's number if you wish to speak to him too. Just let me know." The surgeon stood up, leaving the file on the table and was about to walk out when Carlos' voice stopped her.

"Wait, will Santiago's um," He cleared his throat uncomfortably. "Is everything, functional?"

"Well, there is no tissue or nerve damage, so I feel confident in saying that penile erection will be more than probable and possible, but, and this is very preliminary and will need to be checked when Santiago is older, there is a very low chance of being fertile." Carlos looked down at the floor as Sofia nodded. The doctor returned the nod before walking out through the door.

As soon as the door clicked shut, both parents turned to one another and let their hands separate. The yelling started shortly after, blaming each other for what had happened, and going round in circles. After an hour, Carlos suddenly fell silent, tears welling in his eyes and beginning to fall down his face. The shout that was about to come from Sofia, died on her lips and she rushed over to her husband, pulling him into her.

"My little boy. My poor little boy. I hated seeing him come home all the time, so sad. I just thought, he would get tougher, start making some friends with the other boys in his class. Stop playing kitchen and ballet class and dolls with Brittany. I didn't know. I didn't know he felt like a girl inside." He took a deep shuddering breath, Sofia's soft hand, rubbing circles into his back calming him down. He stood up straight, pulling the last of his tears from his eyes before clasping both of his wife's hands in his own. "I think we should do what the doctor recommends. Let Santiago be a girl. He, she looks more like a little girl than a little boy, everyone says so, and all her friends and games are girls. I think we should change schools. Let her start again."

The room was silent, and Carlos suddenly panicked that his wife was going to disagree, going to think Carlos had lost his faith in God for wanting to re-invent their boy as a girl. Sofia didn't want to admit that something like this could happen to her child, but she had to admit, everything made sense. How feminine Santiago looked, the games, his, her, friends. The way her eyes would light up at all of Brittany's pretty clothes.

She nodded and kissed her husband on the cheek. "Santana."

Carlos frowned and shook his head. "What?" He asked, pulling away from his wife to look at her properly.

"Santana, Santana Carla Lopez. It sounds nice, don't you think?" Carlos nodded and smiled wide, before they walked back out into the waiting room.

Sofia took Santana shopping the next day, and watched her face light up at all the bright colours and different textures of the dresses and skirts and blouses. She still wanted to keep her jeans and her dungarees and her t-shirts, but now they sat surrounded by their new feminine clothes too.

She spent hours trying on her new clothes and showing her father when he returned home from the hospital. Carlos was taking the transition better than even he thought he would. He was so pleased and proud when he held his little boy, but seeing his little girl, so happy, happier than he had ever seen Santiago, pushed his misgivings aside. That and the lengthy discussion he and Sofia had had with their priest (who had listened to everything, and along with his own knowledge of Santiago, agreed with their decision, assuring them that God wouldn't judge them for doing what is best for their child, especially when God had a hand in making Santana inter sexed in the first place) made him wonder that he had never seen that he had a little girl in the first place.

Two weeks later, her hair newly styled more feminine cut, she started at her new school.

The only drawback was she didn't have Brittany.

Her parents had explained that she couldn't tell anyone how different she was, and that included Brittany, but it didn't make her miss the blonde any less.

Brittany missed Santiago terribly. She didn't even get to see him after the doctors had made him better. Her mother (who had been told by the Lopez's that they thought Santiago turning over a new leaf with new friends at a new school) had explained carefully that he was okay, but had to move away to be happy without bullies.

She hated school without Santiago, the other girls weren't as fun to play with, weren't as inventive or as carefree to make up stories with her and there was no one to whisper how clever she was when Brittany pointed out a flower or cloud shape in the sky.

So a few weeks after Santiago's accident, a determined five year old Brittany, wriggled through the gap at the bottom of the fence at the end of the day and ran to Santiago's house. She reached the door, red faced and out of breath, pushing onto her tip toes to reach the door knocker.

When Sofia opened the door, and saw Brittany, her initial instinct was to close the door immediately, but seeing that the little girl was completely by herself, she paused. The pause was long enough for Santana to approach the door in curiosity, and for Brittany to see past Sofia to where Santana was standing, a shy smile on her face at seeing Brittany.

Brittany darted underneath Sofia's arm that was still holding the door open, and flung her arms Santana's neck. "Santi! I've missed you so much!" Brittany squeezed her once more before stepping back and studying her friend. "Why are you wearing a dress Santi? I mean, you look very pretty, but I thought boys weren't supposed to wear dresses?" She tilted her head to the side curiously.

Santana dropped her eyes to the floor and started to pull and twist at her fingers. "I'm not a boy anymore Britty. And I have a new name. Santana."

Brittany didn't even hesitate when she answered. "That's a really pretty name." Brittany reached out a tugged at the white blouse Santana was wearing. "You're a really pretty girl Sanny. A much prettier girl than a boy." Santana looked up and smiled widely, not having expected this reaction; her parents told her people would think it was weird if they knew and she could understand that. But Brittany just told her her new name was pretty. That she was pretty. That she was a better girl than a boy, her transition not bothering Brittany at all.

"Really?" Santana whispered. Brittany nodded, rocking on her heels a little.

She took Santana's hand, about to pull her up to her bedroom to play, when she suddenly heard her mother's voice in her head reminding her about manners and she turned back to where Sofia still stood at the door, shocked at the little blonde's reaction. "Dr Lopez can I go and play with Sanny please? Wait," Brittany turned back to Santana worried. "You still want to be my best friend right? Just 'cos you changed your outside doesn't mean you don't like me anymore right?"

"You're still my best friend Britty."

"Score." Brittany turned back to Sofia. "So can we?" Sofia nodded mutely, before watching Brittany pull a beaming Santana up the stairs behind her. She shook her head in a mixture of amusement and amazement, before walking into the kitchen to call Annie and tell her that Brittany was safe.

Annie had taken Santiago's transition to Santana surprisingly well. At first she was shocked, and laughed a little, sure that Sofia was joking. But when she heard the distinctive thumping of her daughter coming down the stairs and turned to greet Brittany, she saw the truth of Sofia's words. Next to Brittany, clutching nervously onto her hand at Annie's curious gaze, was Santiago. But with slightly longer hair, falling softer around her face and wearing a pretty light coloured skirt and blouse; definitely Santana, not Santiago any more. Annie still hadn't said anything, and turned to look at Sofia, who was clasping her hands in her lap and her eyes were flickering between the two girls and Annie in worry. Annie softened, seeing the fear in Sofia's eyes and the way Santiago (no, Santana, she corrected herself) couldn't meet her eyes, sideling closer towards Brittany as if for protection.

Annie smiled. "Hello Santana. You look very pretty in your new skirt." Annie saw Sofia's shoulders relax out of the corner of her eyes, and Santana smiled wide.

"Thank you Mrs Pierce."

"Mum? Do I have to go yet? Me and Sanny were half way through a tea party. Please can I stay longer?"

"If that's okay with Sofia," Sofia nodded and smiled, so relieved at not only Brittany, but Annie's reaction, she was sure she would agree to anything. "Then you can stay a bit longer. Go and enjoy your game girls." Annie loved the way Santana's face brightened and her smiled grew impossibly bigger at being addressed as a girl, watching Brittany pull her back up the stairs.

Brittany still hated without being Santana at school, and after escaping through the gap in the chain link fence and running to Santana's school three times in two weeks, the Pierce's looked into Brittany changing to Santana's school.

After two weeks and a very long (and boring, Brittany thought) conversation about how Brittany could never tell anyone that Santana used to be a boy and still had some boy parts, Brittany and Santana walked into the school, pinkie fingers linked. Once again inseparable, but this time, content to be friends with just each other.

Santana had become a lot more reserved since the fight in the playground, and found it harder to make friends at her new school, and so, every day, it was just her and Brittany.

And she wouldn't change that for anything.

Lima: Late 2011:

"San! San! Where are you?" As soon as she saw it, white and intimidating and exciting, Brittany had grabbed it from the kitchen table and ran to Santana's house. "Saaaaan!"

"Brittany! Please stop yelling! She's upstairs in her room." Sofia was used to Brittany's over-exuberance and was expecting her this morning, but that didn't make her yell any less painful.

Brittany grinned sheepishly, a dusting of pink highlighting the freckles along her cheeks. "Sorry Mrs Dr L." She showed what was in her hands as an explanation, before running up the stairs, taking them two at a time and bursting through Santana's bedroom door.

Santana was only half way dressed when Brittany burst in, half leant over her bed to pick up her bra, and Brittany momentarily forgot what she was there for. "Wow." She couldn't help the small movement of her tongue running over her lips and unashamed staring at Santana's exposed chest, until her hands instinctively clenched into fists and the sharp rustle of paper brought her back to her senses. She blushed darker, both at what she could see and the excitement from what was possibly clutched in her hands. "Mine came. I haven't opened it, like we agreed. I came straight here, as soon as I saw it on the kitchen table." She was stopped by a loud burst of laughter from Santana, and she frowned slightly in confusion. "What? What's so funny? I don't get it?"

Santana quickly pulled her bra on before walking over towards Brittany. She leant forward and pushed her hands into the pockets of Brittany's trousers. Brittany's trousers covered in multi-coloured ducks and rainbows bursting from white fluffy clouds. "You're still in your PJ's Britty." Santana said sweetly.

Brittany looked down, and smiled coyly. "Oh, yeah, well, I might've gotten a little, overenthusiastic. Do you have your letter too?" Santana swallowed heavily and walked over to her side table, where the large, thick white envelope with 'University of Berkeley, California' and the seal was immediately obvious. Brittany held up her own, flipped it so that the flap of the envelope faced her. "Do you want to open your own or do you want to open mine, and me open yours?"

Santana cleared her throat, eyes flickering between her own envelope and Brittany's, before looking back up into Brittany's eyes, her blue, comforting eyes. "No, open our own."

Brittany nodded, about to push her thumb under the flap. "Together?" Santana nodded once, curtly, lifting her slightly shaky hand to the flap of her own envelope. "On three, one, two, three." The room was silent except from the sound of sticky paper being pulled apart, then the rustling of pages being pulled out and read, quickly, looking for the single line that would determine the next few years of their life.

Brittany looked up first; Santana's eyes were still flickering all over the page, but Brittany didn't know if that was a good thing or a bad thing, as Brittany was a much slower reader than Santana. One of the many drawbacks of being dyslexic. Santana could feel Brittany's eyes on her, and she slowly lifted her own. She reached out and held Brittany's hand between them.

"Well?" Santana's voice was forcibly calm, monotonic, and Brittany couldn't tell anything. She wasn't sure she could speak, so instead she turned the page around so Santana could read it.

"Dear Miss Pierce," Santana's voice was tiny, quiet as she mumbled out loud the words she was reading. "We are delighted to offer you a place at the University of Stanford to study Philosophy, for the winter semester of 2012." Santana stopped reading, then began again, louder and clearer, before she pulled Brittany towards her whispering congratulations into her ear and pressing kisses to her hair and cheeks and forehead. Brittany couldn't stop the giggles escaping, but soon gripped Santana's forearms, pushing their bodies apart.

"Did you," Brittany swallowed, she wasn't sure if Santana's reluctance to tell her what her letter said, and her over enthusiasm about Brittany gaining her place was to make Brittany forget about the Berkeley letter or because she had also got her place. "Did you get in?" Santana smiled before she turned the letter around for Brittany, who could only focus on the one word. Accepted "You got in!" Santana nodded before throwing both of their letters onto her bed and tugging Brittany towards her by her hips, lips crashing together instantly. "Sanny, we're going to California together!" Santana nodded enthusiastically, still unsure of her voice and Brittany's smile morphed into a smirk as her right hand travelled between their bodies, down Santana's soft, exposed stomach, and over the front of her boxers. The smirk widening, both pairs of eyes darkening when Brittany squeezed gently and felt Santana respond. "How about we celebrate?" Another squeeze, followed by single finger running down the cotton of her increasingly tight boxers, caused Santana's breath to catch in her throat, before navigating Brittany towards the bed.

A/N: Thanks for reading!

So, I'm sorry if my university timing and courses weren't accurate. I spent about 2 hours trying to navigate all of the university websites and Google maps trying to figure out geographically would be the best ones, and then trying to figure out which courses they would actually be eligible for, which, given I'm not American, was actually quite difficult, so if I've done something a little…wrong, just go with it please!

Should I continue? Let me know :D Review please? ^.^
