After the events of Season 4, they went their separate ways: Brittany at MIT, Santana in NY, each with the hope of getting back together in the future. But what happens when Brittany gets engaged? Will Santana win her back or will she be forced to move on? Rated M for sweet, sweet lady kisses ;)

A/N: I do not own Glee nor Tarzan. The people who do are much cooler than me,

This is my first Glee fanfiction. Canon up through Season 4.

I know there are several similar fanfics with Brittana getting married to someone else, but I felt inclined to write this just because. I apologize for any mistakes.

Prologue

Santana's POV

"And then there's Santana"

I look up and see Brittany coming towards me. Next thing I know, she's clinging to me like I'm the last person on Earth. But then again, that's just how Brittany hugs. She makes you feel like you are the only two people in the universe. Everyone in the room tearfully looks at us waiting for the blonde to continue but all they heard were sniffles. Heck even I'm waiting for Brittany to say something. Maybe something like, "You're my best friend, the love of my life. I am going to miss you more than you will ever know. I love you." Ok fine, that may be wishful thinking but anything would work right now. Until I felt her squeeze me tighter. Then I knew.

"Oh man. You don't have to say anything, Brittany."

Even through the sobs and the months apart, I could still read my best friend. As much as I want to hear those words again, Brit has been through enough stress these past few weeks. She quickly pulls away before any more tears can escape. As soon as she leaves my arms, I miss the contact. I see Mercedes eyeing me carefully as they take the stage.

"Are you okay?" I feel arms wrapping around my shoulders. Our time on the Troubletones brought us together not to mention she was there to help me when Finn outed me. If it weren't for her, Brit and I would have fallen apart long ago. I offer a small smile. Thankfully she understands and thankfully didn't press for more answers. During the performance, I keep my eyes glued on Brittany. Despite Brit's lack of rehearsal for regionals, she moved flawlessly. In fact, she knew the steps better than majority of the Glee Club. When the songs slowed, I couldn't stop the tears coming. This would be the last time I would see Brittany on this stage. The place where she felt most at peace, her sanctuary. When no one could find Brittany during the day, I knew the blonde would be dancing in the auditorium, moving effortlessly to no music. She looked serene, truly beautiful. It is one of the many things I love about her.

"And in first place…. The New Directions!"

Applause rung out in the crowd as the home team celebrated yet another regional win. The club headed off to the choir room to prepare for Nationals, everyone except a particular blonde. I saw Brittany stand on the stage for a few moments longer, basking in the bright spotlight on her. Confetti and flares seemed to die down as she took a seat on the platforms on the stage. The very stage where she performed countless songs with her friends. The stage where she discovered her best friends, dreams, and love. I slowly walk up on stage, carefully observing my best friend. Her crystal blue eyes meet mine as I reach out a hand to her and she takes it for me to help her up.

We walk with our arms around each other, wanting to stay as close as possible.

On our way back to the choir room, Brittany suddenly stops in front of our old lockers.

"Santana, earlier in the choir room…" she said while trying to choke back a sob, "I- I just want t-to tell-l you…" I take her face in my free hand and whisper to her.

"Shh, it's okay, Brit-Brit. I know. You don't need to say anything." My voice comes out raspier than usual, but it seems to sooth her. I envelope her into a tight hug, staying like that for a few moments.

After the surprise wedding (I swear I'm going to have fun rubbing this is Berry's face), I walked towards the parking lot still dazed about the events of today.

"Santana, wait"

I turn towards the voice even though I know the source. Trouty is running towards me. What does he want?

"Um thanks for helping out," he mutters. Who does he think he is?

"Yea whatever, you know I only did this for Brit." I get ready to turn back when I feel a hand on my arm.

"Look, I know I'm not your favorite person since I dated Brittany, but without you here, Brit would have been lost. I know you still love her, Santana. And I'm pretty sure she still loves you."

I look up at him and I'm sure my mouth is hanging open a bit.

He continues, "I knew she loved you all this year. I couldn't get her to open up like you could and I would always see her looking at pictures of the two of you. What I'm trying to say is, I'm sorry if you think that I stole her from you, but she was never mine. She's always been yours." With his spiel finished, Sam walked away. All I could do was stare at the space which he previously occupied. Brit still loves me? Of course she does! We are meant for each other. But hearing it from other people makes it seem even more real. I let out a small laugh as I make my way to my car, for real this time.

"What's so funny?"

I smile at the voice and look up into the most beautiful blue eyes as I shake my head slightly.

She walks closer, "Since you're heading back for New York tomorrow, do you wanna stay in the castle tonight?"

"Of course" I link my pinky with hers as we climb into my car and head for the park near her house.

I should explain. When Brit and I were 12, we wandered into the woods in her backyard. Brit wanted to explore the "Enchanted Forest" as she liked to call it and I was trying to make sure she wouldn't get hurt or lost. Plus it's fun going on adventures with her. Anyway, in the deeper parts of the woods, we found an abandoned treehouse…

Flashback

"Sanny, look! It's a deserted castle" I look up and see a dilapidated structure in a tree. We were in the woods somewhere between the park and Brit's backyard. I look back at my friend and see her trying to climb the stray rope attached to the "castle".

"Brit-Brit, that's not a castle! Some lazy bum probably forgot to take it down. Get back, you'll fall!" She reaches for a nearby branch and continues to climb.

"I'll be fine. I have you here!" I blush slightly at her statement. I always have been her protector.

"It's the castle of the forgotten princess. The forest fairies must have taken her to another castle to escape the ogres!" Oh how I loved her imagination.

"Then how do we know the ogres aren't still here?" I offer with a smirk.

"We'll just have to build a better castle with better defense to keep them away. Come on Sann-AH!" A branch snapped as I saw my best friend falling from the structures.

I quickly run over as Brittany is rapidly approaching the ground. Without a second thought, I dive to the area. And then I feel a large weight fall on top of me.

"OOMF" I'm on my back on the dirty forest floor and Brit fell pretty hard on my chest. That's why my heart is beating so fast, right?

"Sanny are you okay? Are you hurt? That was a pretty bad way to try to catch a damsel in distress don't you think. You're my knight in ripped up jeans" She leans down and pecks my cheek. I continue to blush.

"Anything for my princess."

Yes, even then I knew there was something between Brit and I. We rebuilt the treehouse and made it our own. The guys at Home Depot helped secure it, but we made it our sanctuary. I park the car by the woods and we walk pinkies intertwined to our destination.

After a few short minutes, I recognize the carving on the large tree. B & S 4ever was neatly carved with a large heart. We started climbing the ladder to the main room of our fortress. We considered putting actual stairs in, but decided it was more secretive with a ladder. Brit climbs through the hatch first and pulls me up. Once I stand, I fully take in our paradise. In one corner of the room is a bookshelf stuffed with our favorite novels as well as some coloring books for Brit and copies of our yearbooks. On the other side, a cooler and basket of food and drinks lie. When we were younger we mostly kept soda and candy up here. Now we have some vodka and tequila stashed up here for our more "relaxing" times. My favorite portion of our castle is not in this room however. In the back left corner of the room, the wall panel is loose. I gently press it causing the hidden space to open revealing a spiral staircase. I glance back at Brittany and smile as I begin to ascend the stairs. Man I never realized how steep these steps were! When we reach the top, we link pinkies once again and step forward into the "royal bedchamber" as we called it. A queen sized mattress sits on the wood. The cone-shaped ceiling contains windows on some of the slants giving clear access to the night sky. On the west side of the room is a large window door with a small balcony. The east side has a ledge we use as a window seat. This way we can witness either the sunrise or the sunset whenever we spent the day here. Looking back at the bed, I notice cotton sheets thrown on in. It looks like someone has been sleeping up here recently.

"I couldn't go back. I would keep thinking and eventually fall asleep here." She seemed to be reading my mind. "Don't worry, our special sheets are clean and folded in the basket in the corner." She giggled. Yes, we kept satin sheets in here for special occasions (i.e. Valentine's Day, day before I left, etc.). I smile at her and gently guide her to the mattress.

"C'mon, let's lie here."

We are lying on the mattress stargazing as we cuddle closer to each other. I've missed this. I miss hearing her heartbeat as I rest my head on her chest. I miss her small giggles when we make up stories about the stars in the sky. But unfortunately, this all has to end.

"Brit, I leave for New York in the morning." I glance at her eyes, searching for an expression.

"What's going to happen to us?" She sounds so scared, so hurt. I sit up keeping my eyes locked with hers.

"What do you want to happen?" I made the decision last time. I don't want to make that same mistake again.

"I love you, Santana. But I hate not seeing you. I don't know if I'll be able to handle it again." Tears are starting to surface in those beautiful baby blue eyes. I quickly try to wipe them away before they have a chance to fall. Then I remember the object that's sitting in my coat pocket.

"I love you too, Brittany. I have an idea. It's not great, but it's better than the alternative." She looked at me with a questioning glance.

I reach into my pocket and pull out a box. Brit gasps.

"It's not what you think Brit." I laugh. Though I really wish it was. I open the box to show two simple silver rings. Each have a small studded heart on it and an engraved message inside.

"These are promise rings. Brittany Susan Pierce, I promise that I will always love you. That when we eventually find our way; after school and auditions and whatever else there is, I want to be with you. Proudly so." I carefully explain it, hoping she likes the idea.

"Santana Diabla Lopez, I promise that I will always wait for you. That no matter how hard it gets, I will always love you."

I'm shaking as I pick up one of the rings and take her hand carefully guiding it onto her ring finger. She smiles a million watt smile as she does the same for me.

I cup her face in my hands and slowly bring it closer to me until we are centimeters apart.

"San"

That's all it takes as I close the gap and softly kiss her. Oh god the last time we kissed was when I left for New York, but it was merely a peck. The last time we shared a kiss like this was before we broke up. I've regretted my actions ever since that day. I should have worked harder instead of being so quick to give up. Our soft kiss soon turned into something more. Our lips moved faster and harder. Neither of us could keep our hands to ourselves as my fingers buried themselves in golden locks and her delicate hands caressed my sides. I couldn't stop the moan escaping my lips as Brittany began sucking on my bottom lip. I soon rolled on top and began kissing her neck eliciting a gasp.

"Santana"

"Yes, Brittany?" I pulled back and stared into her eyes. Her blue orbs were darker than before. Full of desire.

"Since we won't be together for a while, I want to spend these moments with you. Truly with you." I wait for her to continue.

"Make love to me, Santana."

"As you wish" I whisper as I capture her lips once more. My hand gently caresses her cheek, feeling her soft skin beneath my fingertips. I feel a hand creeping to my back, trying to pull my jacket from my body. I shrug it off my shoulders and reach for Brittany's sweater. Our lips part just long enough for me to pull the clothing over her head. We slowly continue to remove each other's clothing. We are in no rush as we never want this night to end. Once we are completely exposed to each other, I shudder at the sudden cool air hitting my body. Or maybe it's because I have the most beautiful, sexy girl next to me. I feel her lips on my neck as she quickly finds my pulse point bringing a moan from my throat. I place my legs on either side so our centers come into contact causing groans to fill the room. I kiss down her neck, across her collarbone, and back up to meet her lips as we move our bodies in perfect syncrasy. The tension in our stomachs build as the movement becomes more desperate.

"Santana, please"

"Oh god, Brittany"

The feeling becomes too much as the room fills with gasps and moans as well as a few "I love you"s. I continue to kiss her neck. But when I pull her face to mine, I notice tear streaks on her cheeks. I gently kiss them away.

"San, I don't want this to end. I don't want you to leave. I don't want to leave." She manages to express her fears but her body is shaking and I know she needs this. She needs this moment the most.

"Shh, I'm here Brittany. I'll always be here. Don't you remember when we were here after I came out to my abuela? When I couldn't stop crying? You sang to me."

Come stop your crying, it'll be alright.

Come take my hand, hold it tight.

I will protect you from all around you.

I will be here don't you cry. She started crying harder this time. No, no, no more crying. I lay next to her, pulling her head onto my chest slowly running my fingers through her hair.

For one so small, you seem so strong

My arms will hold you, keep you safe and warm

This bond between us can't be broken

I will be here don't you cry. Her crying subsides as she joins in.

Cause you'll be in my heart

Yes you'll be in my heart

From this day on, now and forever more.

You'll be in my heart

No matter what they say.

You'll be here in my heart

Always I lean into her ear and clasp our ringed hands together

always

With one last kiss, we drift off to sleep but not before I notices the gleam of the moonlight off our new promises.

I begin to stir from my slumber when I feel soft lips on my chest. I smile as the memories from last night flood back. I open my eyes and are met with a beautiful angel above me with golden locks flowing on down her shoulders. Sapphire eyes look back at me as her soft pink lips draw closer, "Good morning sleeping beauty"

I let out a soft moan as we lips dance over mine. As much as I want to stay here, I know I need to leave soon. Unfortunately, I have an early flight back to New York. After a few more moments to ourselves, we reluctantly get dressed and climb down from our sanctuary. I sigh as we walk back to the car and drive to the airport (Brit is taking my car back to my parent's house).

"I guess this is it, the end" Brit sadly states as we pull up to the curb. I look back at her and shake my head as I rest my forehead against hers.

"No Brit, this is only the beginning. I made a promise that I will always love you and that I will always come back to you. We just have to be patient."

We lock eyes and slowly lean in. The kiss started soft and sweet, but soon turned desperate like we never wanted to separate. Until we heard some asshole yelling for us to move the car. We reluctantly pull away, tears in both our eyes.

"I'll see you soon Brit-Brit. I love you."

"I love you too, Sanny."

One last peck and I'm backing away, keeping our fingers intertwined for as long as possible. As soon as I am out of reach, I give a small wave and turn towards the building, constantly looking back over my shoulder.

I'm sitting at the gate, twisting the ring on my finger. With this ring, I promised her that I'll be back. I gently remove the ring and look at the inscription I had engraved: Proudly So

I smiled to myself, dreaming about when that day would come.

A/N: So what do you guys think? I have a basic direction for how I want this story to play out but I am also looking for suggestions for a few things. Those times won't come for a bit. This was also my first attempt at writing a sex scene. So sorry if wording seemed awkward.

If you want a better visual of the tree house, I will be posting the pictures on my tumblr (sentimental-idiot). Hopefully I'll get to that this weekend. I mostly checked out tumblr and pinterest for some inspiration. I just like the idea of having a window on the ceiling so you could sleep (or "sleep") under the stars.

Anyway, reviews are helpful and much appreciated!
