Summary:He'd only introduced Carole to his father so that he could get closer to Sebastian - it was just a simple crush at first. He didn’t expect to become his stepbrother. And he certainly didn’t expect to actually fall in love. Kurt/Sebastian and Kurt/Blaine.
At first it’s the shallow things. Sebastian’s hair is a little trendy, but it works for him somehow - though sometimes he does imagine running his fingers through it, feeling the softness of it without any gel or product. And his eyes are probably the most gorgeous shade of green Kurt’s ever seen. The small moles dotting his left eye are impossibly cute, and his mouth - Kurt didn’t think that just a mouth by itself could be sexy, but Sebastian makes it possible. His lips are just small enough, plump but not too full with a perfectly shaped cupid’s bow up top.
Kurt tries not to be too obvious in his staring. Sometimes he thinks he’s successful, like when he watches Sebastian during group - and Sebastian talk lot o he kind of has an excuse. And then there are other times - like when Rigo talks about what it was like growing up in Puerto Rico - that his gaze just... drifts over to Sebastian. And Kurt’s not sure if he’s wearing a neon sign or something that reads “I’m staring at you” because almost every single time, Sebastian catches him in the act. And he just - smiles. That slow, lazy smile, almost like he’s hiding something.
Of course Kurt’s first instinct is to look away. There are a few times when he does, and he has to force himself to think of the world’s unsexiest things (Coach Tanaka in drag, Figgins in a wet t-shirt) because that damn smile makes him more flustered than he’s ever been.
But when he doesn’t look away, when he meets Sebastian’s gaze head-on and matches that smile - it’s a huge confidence surge, at least for a while. It makes him think - you’re capable of attracting guys. You’re not bound to be the ugly duckling forever.
And that’s when he remembers that he’s talking about Sebastian. Sebastian, who’s probably got an equally attractive, confident, smart boyfriend and Kurt doesn’t fit in that picture at all. He doesn’t ask if Sebastian has a boyfriend - there’s obvious, and then there’s way obvious - and Sebastian’s never mentioned it. But honestly, how can he not be attached?
He wonders sometimes if either Rigo or Jake or Seth is secretly Sebastian’s boyfriend. In the end, none of them seem to be his type, not that he’s spent much time considering what said type might be.
Sometimes he tries to gather hints though. He’s casually mentioned his current involvement on the cheer squad, and he could have sworn he saw Sebastian’s eyes flash with curiosity. Glee club is another thing that seems to pique his interest.
“What kind of music do you guys do in glee?” Sebastian asks one day as they hang out in the clinic. Carole is in the next room over, administering two antibody tests.
Kurt flips through the January 2010 edition of Vogue. “We try to do all kinds, but our teacher seems to be forever stuck in the 80s. What about your group?”
Sebastian chuckles. “Just turn on the radio, we’ll find some way to make it a cappella.”
“Sounds like fun,” Kurt says with a smile, and he musters up the courage to add, “You should sing for me some time. I’m sure you have a wonderful voice.”
“Well, I don’t want to brag...” Sebastian drags out playfully, and Kurt laughs in response. “But yeah, I am pretty good. Maybe at the open house. We could totally sing a duet.”
Kurt smiles and says nothing, just continues to page through the magazine.
“I’m serious,” Sebastian says, leaning over Kurt from his sitting position on top of the counter.
Kurt looks up and sees him mere inches from his face, and he forces himself not to swallow or look away. Instead he stares at the space right between Sebastian’s eyebrows, his cheeks growing warm. “About what?”
“The duet.”
“Okay, we’ll sing together,” Kurt leans back in his chair a bit, laughing uncomfortably. It probably isn’t a good idea since his stomach is already doing somersaults as is. “You don’t have to get all weird.”
That answer seems to satisfy Sebastian, and he leans back smiling. “Nice. So what are we singing?”
---
It’s distracting sometimes - Sebastian’s little quirks, like his facial expressions becoming suddenly intense and then immediately relaxing. Those quirks are small details that Kurt would never remember if it were anyone else, but because it's Sebastian, he does.
The way Sebastian cocks his head back when someone is speaking. The way he interrupts Seth’s stories with snide comments (the rudeness of which is normally a huge turn-off for Kurt, but somehow it isn’t, this time). The way he details those summers with his aunt in Paris like they’re the best things to have ever happened to him. The way he can be completely in-your-face and yet still adore his wonderful mother.
And when he talks to Kurt - when he leans into Kurt’s personal space - that’s what really gets to him. Because Kurt’s gotten so used to changing by himself in the corner, facing the wall in the locker room just to avoid accusations from the other guys about checking them out. He’s gotten so used to the locker shoves and the dumpster tosses that when Sebastian invades his space like this with no intention of hurting him? He’s just a bit guarded and a little shocked, but his heart feels light enough to shoot off into the clouds.
Sebastian doesn’t treat him like a leper or some sort of walking abomination - he just treats him like a normal person. And that’s all he’s ever really wanted.
It’s things like those that get to Kurt, hook, line, and sinker.
But when he thinks about it, there really isn’t much he knows about Sebastian. So he’s openly gay. So he’s a member of the Warblers. So he has that cocky smile permanently affixed to his face. So his parents got divorced when he was young.
That’s about the extent of what he knows.
He imagines that this interest with Sebastian... is like nicotine. The first few hits are for curiosity. But soon he needs more, wants more.
There is so much to discover about him.
“Are you bringing your dad on Sunday? We’ve had a lot of positive responses from parents who’ve come in before,” Sebastian mentions on the Monday before open house.
Kurt bites his lip in thought, pulling his cardigan tighter. “I don’t know... Is your mom going to be there?”
Sebastian gives him a strange look. “Well, yeah. But she always is, every year.”
He lets that sink in for a moment. This is the perfect opportunity. If he wants to know all there is about the boy in front of him, this is his chance. It isn’t... being pushy, it’s just curiosity.
With a smile, Kurt answers, “I’ll try to get him to tag along.”
He only feels a little bit guilty.
