A/N: Guess who saw the Amazing Spiderman yesterday. Go on, GUESS.

"What exactly was that back there?" Kurt sounded angry as the rooftop door shut behind him. Sebastian didn't dare turn, instead tightening his hands on the wall that separated him and the city, that protected and tempted all at the same time. The instinct coursing through him was singing in his veins, calling to him as it had for the last couple of weeks, and he wondered what Kurt's reaction would be if he suddenly threw himself over the edge, reaching out to swing at the last moment, knowing that Kurt's eyes, blinding blue as ever, would be following him in wonder.

"What was what?" He decided to play innocent, turning to face Kurt with one hand still firmly gripping the wall for balance he didn't need.

"What was- so, let me get this straight. You come over for dinner-"

"You invited me."

"-You turn up with a black eye that you won't explain-"

"I walked into something."

"-and then you fight with my father over some ridiculous guy who runs around in spandex supposedly saving the world one car thief at a time."

"He was being- what's wrong with spandex?"

"What isn't wrong with spandex, Sebastian, for the love of- it's not important, okay? Just maybe hold the claws in next time you meet my family, I think Finn was about to punch you for being rude to my Dad." He crossed his arms, a huff of breath escaping as he stared out into the night. Sebastian bit his tongue for a second and turned back to the city, watching the lights below him as hundreds of people went about their lives. Eventually he heard a soft sigh from behind him and felt a presence at his side as Kurt came to lean next to him, staring down at the streets below and resting his hand dangerously close to Sebastian's. Where he had felt temptation at jumping, knowing that he would be able to catch himself, now anxiousness flooded through Sebastian. Would he catch Kurt in time, if he were to fall? He hadn't had the opportunity to test what he could do; would he fall fast enough- would the cable hold the weight of them both, or would they plummet to the ground? His head spun with the thought of seeing Kurt's form fall the incredible distance, breath coming faster as panic flooded him.

Fucking senses.

"-going on with you, I mean, you always look hurt and you won't talk to anyone and don't think I haven't noticed you lurking in the back of classrooms and refusing to meet everyone's eye- will you just… talk to me?" Kurt sounded exasperated, his eyes wide and pleading. Sebastian hadn't caught the first part of his sentence, too swamped in his own feelings of worry to notice what Kurt was saying. He hesitated too long in attempting to backtrack and remember what was being asked, and the concern in Kurt's eyes only intensified.

"Or you could talk to someone else, I mean…"

Sebastian needed to sort out this concentration thing. He could hear his own heart thudding, knew that right now at this moment a short woman was dropping her purse heavily onto the sidewalk and stooping to retrieve it, could even feel somehow the anger radiating from a man a block away, but he couldn't quite focus on the quiet voice of Kurt, standing immediately next to him.

Kurt stepped closer.

And wow, there was that concentration. Suddenly Kurt was everywhere, his mouth dangerously close to Sebastian's, the heat of him filling the space between them, his eyes now almost hypnotic, holding his attention as if he was chained to the other boy.

"Sebastian…" He fought the urge to look down, to see if his body had betrayed him again, if his freaky sticky hands had attached themselves to Kurt, if that was the reason for this connection between them. He was silent still, and Kurt seemed to give up as he stared at Sebastian. He nodded once and stepped back, breaking the strange connection between them and turning to walk away.

"Wait, Kurt-" He turned back, raising his eyebrows at Sebastian.

"I need to tell you something- it's, it's about the guy and the spandex and the- well, it's about, um…" Kurt seemed to lose attention at his mention of the 'vigilante' the police force seemed to be so interested in, and rolled his eyes at the night sky, crossing his arms once more. Sebastian floundered, grappling for the way to phrase his secret to the boy in front of him and clutching tighter to the wall until he felt it shift and hastily withdrew his hand, wary of his newfound strength.

"Look, Sebastian, I should really go inside." Kurt turned fully now, taking a couple of steps towards the large door they had both emerged from. Sebastian's hands carded through his hair once as he stared at the city again, before making a snap decision and turning fully, quickly.

He'd made the decision before he'd even really thought of it, translucent cable shooting out and attaching itself to Kurt's slender hip, dragging until he was pulled in close to Sebastian's chest, closer than before and breathing more heavily. The speed at which he had been wrenched across the small space knocked the breath out of him, and Sebastian could feel the heaving of his chest against his own, the heartbeat slightly out of time with his own. His hands rose as if of their own accord, cupping around Kurt's face and framing those fucking eyes perfectly as he leaned in, capturing Kurt's mouth instantly. It couldn't have taken more than a second or so, but to Sebastian it felt like minutes, noticing the way Kurt's eyes widened a little as he was caught, his mouth dropping open as he swung around and towards Sebastian. His expression had a split second to flash between horror and awe as the reality of the situation kicked in right before Sebastian crashed their mouths together, tangling long fingers into thick brown hair. Kurt was frozen against him, lips unyielding in shock, but he melted into the kiss seconds later, leaning into Sebastian's body and tentatively kissing back, feather light touches against Sebastian as his hands crept into the space between them, bracing himself on Sebastian's chest as he leaned an inch back out of the kiss.

"You're- Oh my God, you're-" He was cut off as Sebastian surged forwards once more, more violently this time as he held Kurt impossibly closer, careful not to pull him too close (his bathroom still looked like he had set off a bomb in there after the sleepy disorientation of last week).

"Kurt? Mom says- oh." They broke apart and Sebastian registered Finn standing in the doorway, tall yet somehow awkward, hovering in the doorway. He shuffled his feet, looking down as he spoke once more.

"Uh, Mom says your Dad wants you to come back inside." Sebastian wasn't surprised; the look that he had received from Burt Hummel as he had followed Kurt onto the roof had made him want to track down all weapons in the house and bind them up in web-shit until they were unreachable. Kurt hadn't felt the same fear; he had merely glared briefly at his father and tugging at Sebastian's hand until he followed him.

"Yeah, Finn, I'll be right in." His gaze was still fixed on Sebastian, blue eyes staring into green as he called to Finn. Emotions whirled in his eyes, curiosity blending with shock behind pupils that had blown wide with the closeness of their bodies. His hand was still resting on Sebastian's chest, and it began to tighten into a fist before he jerked it back to his side almost as an afterthought, turning to stare at Finn as his stepbrother remained in the doorway.

"I said I'll be right there, Finn."

"Yeah dude, it's just Burt says-"

"Go back inside, Finn!" His stepbrother looked surprised at the outburst, and reeled backwards for a second before glancing back down at his feet, lower lip protruding in a pout that looked silly on a boy of his height. Kurt seemed to soften at the sight, however, and his voice was more gentle as he continued.

"I'm coming right now, Finn, okay?" The other boy nodded and stepped back into the apartment, and Kurt took a few steps in his direction before turning back to Sebastian.

"We're gonna talk about this later, right?" Sebastian nodded once and smirked, noticing Kurt copy the expression back.

"Come on then, let's see if Dad will really work up the nerve to kill you." His smile grew and he turned again to walk back through the door.

-All officers are required to immediately-officers down, backup urgently required-

Sebastian whipped around. The sirens seemed to fill his ears, although he knew that they were far below him, and he heard Kurt's Dad's footsteps thundering behind him as he responded to the call. Kurt had looked back once more, noticing Sebastian's reluctance to follow, and listened for a second, hearing the sirens, before raising an eyebrow at the other boy.

Sebastian's smile broadened and he shrugged at Kurt, gesturing towards the city below him. Worry briefly flashed in Kurt's eyes, but the curiosity lingered as he took in the shape of Sebastian, framed by the city sprawling far beneath them.

"Gotta go, babe." Kurt huffed and shook his head slightly, gaze snapping back as Sebastian vaulted over the edge, plummeting towards the ground below in the blink of an eye. Sebastian registered the sound of him running to the edge and leaning over, the wall that had cracked under his hand earlier crumbling slightly as Kurt leaned over to watch Sebastian fall. He prayed that Kurt would be smart enough to not lean over too far, and caught himself on a sill on the window opposite, long cord shooting in front of him and securing itself and him, supporting him effortlessly as he caught a rhythm in seconds. He heard Kurt's intake of breath, high above him at this point, and a soft voice whispering.

"Oh, I'm in trouble."

He grinned again and reached into the back of his hoodie, sliding the soft material down and over his face as he flipped in the air, conscious of the one-man audience on the rooftop above.

Yeah, freaky mutant shit has it's perks.
