AN: I'm uploading here because I've always loved how easy is to work with, but I'll be updating both here and on my tumblr. Also this starts out with a lot of klaine initially, but that's only to set the tone of their relationship really. It's pretty Sebastian/Blaine/Seblaine-centric in future chapters.

Also there will be klangst, sebangst, and seblangst. So if you're looking for a light fluff piece about Blaine's senior year this isn't the right fic for it.

"Which one, boo?"

Blaine looks up from beside his bed, where he stands trying to cram his books into his shoulder bag. His gaze fixes on his laptop screen. A video of Kurt is displayed on the screen, the image slightly blurred due to Kurt's budget internet connection. But Blaine can still see worry in his boyfriend's face as he holds up two bowties, speckled green and pale blue, to the camera.

"Since when do you need my advice on this stuff?" laughs Blaine, crossing the room to take a closer look.

"Hey, if it was the first day studying fashion, you'd want a second opinion too!" says Kurt. "You have no idea how nervous I am."

"You shouldn't be, they'll love you," soothes Blaine, taking a closer look at the bowties. "The blue one – it always makes your eyes look that little bit more amazing."

"Thanks," says Kurt gratefully, pulling on the selected bowtie.

"Now do me!" says Blaine excitedly.

"I wish I could, baby," says Kurt hungrily as he pats his bowtie into place. Blaine knows Kurt can't help it. Less than a week apart and they were already going crazy without each other's touch. "I miss you already."

"Kurt," groans Blaine. "Don't say that when I'm already dressed."

"Sorry, sorry," laughs Kurt. "Don't want to make you late for your last first day of school!"

Blaine sees the look of pride on his boyfriend's face and can't help but smile bashfully as he crosses the room to his drawer. By the time Kurt finishes choosing from a selection of half a dozen of Blaine's bowties, it's finally time for Blaine to head off."

"Have fun today, Blaine," says Kurt. "You're going to absolutely love this year."

"Not as much as I love you," says Blaine. And, like always, Kurt rolls his eyes at Blaine's cheesiness, yet struggles to hold back the grin that lights up his face. Blaine ducks down so his face is just inches from the laptop screen, a hand resting on the top corner. "Good luck with your first day. You'll be amazing!"

"Thank you!" says Kurt, beaming at him. "I love you."

"I love you too."

In an attempt to ease Kurt's nerves somewhat, Blaine leans forward and kisses the laptop's built in webcam in what he recognises as an extremely cheesy gesture. It has the desired effect –the sound of Kurt's giggling fills the room before Blaine pushes down his laptop's lid, putting it to sleep. Slinging his bag onto his shoulder, Blaine gives himself a once over in the mirror. He pats down his gelled hair one last time, before heading out the door.

Over the years, Blaine's vision of his Senior year had changed multiple times. This may have something to do with the fact that McKinley is the third high school he's attended. But he could never have quite predicted the feeling which swells in his chest as he walks down the halls. He can't even describe it. It's with a mixture of jubilation, hope, excitement, and even a little bit of trepidation, that Blaine pulls open the door to his locker.

Just a year left of school.

Just a year till I can join Kurt in New York, Blaine thinks. He has no doubt in his mind of where he'll be next year. It isn't like he doesn't have dreams of Broadway for himself, after all. Next year, he and Kurt could make up for all the time they'll lose this year. They'd share a cosy little one-bedroom apartment, close enough to their colleges to allow for late nights and lazy mornings. Friday nights would be spent seeing Broadway musicals, Sunday mornings reserved for taking strolls down Central Park. They'd maybe get a dog if their lease allowed for it. Just a year, thought Blaine, as he unloaded his books into his locker. Just a year and we can have it all.

"Well, if it isn't sex on a stick himself."

Blaine jumps, dropping his history book into his locker with a clang. It couldn't be. It made no sense. After all, who travels two hours just to make a few quick-witted remarks? But sure enough, as Blaine looks up, his gaze meets that of one Sebastian Smythe. The boy leans against the adjacent locker with an air of nonchalance, characteristic smirk adorning his face as he looks down at Blaine.

And, unlike Kurt, who hadn't even noticed when Blaine had transferred, Blaine notices right away that Sebastian isn't in his Warblers uniform. Instead, he's clad in a pair of dark blue skin-tight jeans and a grey v-neck shirt. Blaine can't help but stare a second longer than is warranted at the exposed muscles of Sebastian's arms, crossed over his chest.

"Sebastian, hi!" says Blaine, surprise evident in his tone. "Wh-what are you doing here?"

"You know, it's too easy to get into these little public schools," says Sebastian casually, as if Blaine had never spoken. "I bet they'd take in kids fresh out of juvie." Sebastian wrinkles his nose in contempt as a mob of football players walk past, pushing and shoving their way through the corridor. "Scratch that, they already have."

"Funny, I thought you might have come for the footballers," says Blaine, rolling his eyes.

"You're forgetting that I have a serious innocence kink, Anderson," mutters Sebastian, reaching out to fiddle with the strap of Blaine's bag. He leans forward so his lips lightly graze Blaine's ear. "Blushing virgins really turn me on."

Admittedly, Blaine feels the heat rise in his cheeks at those words. He and Kurt never discussed their sex lives with anyone else. It was theirs, they had agreed, and theirs alone. Their special thing which no one else was allowed in on. But right now, with Sebastian's breath tickling his ear, Blaine feels a sudden urge to list every single kink they had explored together, feels a strange desire to prove that he was no blushing virgin, thank you very much!

But Blaine bites his tongue. If Kurt can manage to fend off a disturbingly curious Rachel, then surely Blaine could handle a harmless Sebastian Smythe.

Harmless, Blaine reminds himself. He pushes Sebastian away softly, his hand meeting what he can tell is a defined chest. Blaine turns back to his locker, intent on hiding from Sebastian any emotion that may betray him.

"And here I was thinking you'd changed," mumbles Blaine, shuffling through the contents of his locker.

"I have changed," insists Sebastian. "But just because I've agreed not to be a dick, doesn't mean I can't -"

"Okay, Seb, I'm gonna be late for class," gushes Blaine, flustered as ever as he crashes his locker closed. "It was nice to mee- well, it was good to see – just… welcome to McKinley."

"Take your time getting your words together," Sebastian calls as Blaine heads down the crowded hallway. "I'll be here all year for you, baby."

Blaine's cheeks redden as he feels the surrounding students turn to look at him, But he can't help but wonder just what it was that brought Sebastian Smythe to McKinley. His stomach knots as he realises it must have been something serious. This was the boy who wrinkled his nose at the 'stench' of public schools, after all.

Blaine shrugs it off. Whatever it is, it means that Sebastian Smythe is here. At McKinley. For the whole year. This definitely wasn't how Blaine had pictured his Senior year.
