A/N: Oop sorry about the angst, actually not sorry but it's necessary so enjoy the closest thing to blangst you'll ever get from me! I still don't own the characters; they belong to FOX/Glee.
"Ok! From the top of the song! ONE, TWO, THREE, GO!" Will, under the pretense of actually directing Sebastian, gave the cue to the band and Sebastian started to sing, starting slow (the song would kick into high gear in the second verse). Kurt, who was actively trying not to stare at Sebastian's hips as he swung them back and forth, was standing just to the side of where Sebastian was singing, waiting for Sebastian to finish so they could practice the kiss.
Kurt was nervous, but excited. Sure, he and Blaine had kissed before so it's not like he's never kissed a boy before, but this was going to be on NATIONAL TELEVISION. And he was being kissed by Sebastian, who may or may not have been (and by that he means totally was) Kurt's celebrity crush since forever; the object of Kurt's most basic desires (before Blaine, of course. But that was different). And now, Kurt was going to be kissed by Sebastian and he could barely contain himself.
"Ok alright! We'll practice the song later!" Will's voice yelling across the gym pulled Kurt out of his thoughts. "Let's practice the kiss now!" Kurt felt himself blush as Sebastian turned and winked at him.
"What's there to practice?" Sebastian drawled, taking a hold of Kurt's hand. "I sing the song, I thrust and grind a bit, I grab Kurt, dip him on this side cause it's my good side," Sebastian had pulled Kurt in flush against him as he spoke before dipping Kurt back and staring right into his eyes, "and then I just do what I do best." And with that, Sebastian leaned down and kissed Kurt, taking control of Kurt's senses. Before Kurt could think too much about it, he brought his hands from where they were resting on Sebastian's biceps and took a hold of Sebastian's face, deepening the kiss. Kurt could feel himself being pulled upright, Sebastian's grip tightening on Kurt's waist, his other hand anchoring himself to Kurt's ass. Kurt's thoughts and feelings and sense were overwhelmed. He could barely process what was going on, all he knew was Sebastian. Sebastian's lips, Sebastian's hands, Sebastian's tongue, everything was Sebastian.
They finally broke apart to the sound of Will clearing his throat. Kurt rested his forehead against Sebastian's, taking a deep breath. "Wow." Kurt heard himself whisper out loud.
"Not so bad yourself." Sebastian smirked and squeezed Kurt's ass before disentangling himself from Kurt to go get some water. Kurt took the opportunity to watch Sebastian as he walked away and when he turned around so Sebastian wouldn't catch him staring, Kurt saw Blaine standing a few feet away, tears in his eyes, and his fists clenched at his sides.
Blaine couldn't believe it. He had heard that there was rehearsal going on for the broadcast today and even though he knew Sebastian would be kissing Kurt, he thought that meant a peck on the cheek. Blaine hadn't expected to walk in on Sebastian groping his boyfriend (again!) as Kurt seemingly tried to eat Sebastian's face off. Kurt was never that aggressive with Blaine when they kissed. But here Kurt was, shamelessly making out with someone that was NOT Blaine. And that pissed Blaine off.
"What the hell was that?" Blaine spoke; his voice strained trying to control his anger.
"Oh hi Blaine. We were just practicing the kiss." Kurt replied, sounding like he wasn't even in the present moment.
"That sure didn't look like 'practice' – that looked like he was taking advantage of you. You know, Puckerman told me that he'd rob you of your virtue and I thought he was full of it, but clearly he's right."
"You're listening to Puckerman on the subject of 'virtue'? The guy who got the president of the celibacy club pregnant? Besides, I told you, this means nothing to me."
"Really? Because you've NEVER kissed me the way I watched you kiss him." Blaine bit out.
"Maybe because you never take control like he did." Kurt said back, his voice laced with irritation and anger.
"Because I didn't want to push you or take advantage of you. You know that. I actually care about who you are as a person and I don't kiss you just in hopes of a quick fuck." Blaine clenched and unclenched his fists by his sides, resisting the urge to touch Kurt and do something he'd regret.
"Oh because you know what I want? You never even asked me if I was ready to do anything or not. What, because I had a bad experience last year I'm too weak and traumatized to suck it up and get over it? If you think I'm such a baby then why are you dating me?" Kurt bit out; offended by the way Blaine was talking to him – like just because Blaine was two years older than Kurt that Kurt needed protecting. Kurt wasn't some damsel in distress. He could handle himself.
At that moment, Sebastian returned to where Kurt and Blaine were standing. "Hey Kurt, ready to practice?" He asked, sliding his hand around Kurt's waist.
"I thought we were." Kurt replied, smiling at Sebastian.
Sebastian squeezed Kurt's waist before whispering "hurry back" into Kurt's ear, then he turned and took his place to practice the song again.
"Well. Looks like I don't know you as well as I thought. You're right. You can handle yourself. Don't let me stop you." Blaine sneered. Kurt lifted his hand in front of his face and inspected his nails, his go to 'you're dismissed' sign. "Wow. So that's how it's going to be." Blaine's eyes lost all trace of warmness towards Kurt. "Fine. But don't come crying to me when he's done with you. In fact, don't talk to me at all anymore. We're done." Kurt's head snapped up in surprise, but all he saw was Blaine walking away.
"Fine. He never appreciated me anyway." Kurt mumbled to himself as he went back to the rehearsal, suppressing the inner voice that told him he was lying to himself and that the best thing that ever happened to him just walked out on him. But Kurt could handle himself. He didn't need Blaine.
