Author's Note: Tiny, tiny, tiny little one-shot to follow "You Make Me Weep". Because Kinn helps me unwind and unblock. And it's FLUFFY.
The first time they sleep-sleep together it scares the hell out of Finn – mostly because he forgot to tell Kurt about it. So when he sneaked into Kurt's bed that night, he got a drowsy yet forceful kick to his shin, and an elbow to his plexus for all his troubles. Kurt still hadn't let go of his underground mindset, and not even the alarm system Burt had installed had managed to sooth all his fears of a robber coming through the window, hiding in his closet and making off with his scarves drawer.
Luckily, as soon as he noticed the lack of prison tattoos and panty-hose masks, he whispered a profuse apology, his eyes growing wide as saucers when he realized Finn was wearing nothing but a pair of remarkably skimpy boxers. He blushed hotly and locked his arms around Finn's neck, swallowing his stepbrother's indignation with a slow, unrelenting kiss. When they broke apart, he let Finn unbutton his pajama top and slip his hands inside. He let Finn pull him closer so Kurt was laying half on top of him, his nose buried in the curve of Finn's neck, one of his legs snug between Finn's thighs. He whimpered a little when Finn's fingers brushed over his nipple, and sighed when Finn's other hand came up to his hair, petting it.
Finn set the alarm to ten minutes before their parents usually got up, buried his face in Kurt's sweet smelling hair, and drifted off to sleep.
Kurt doesn't tell him that it's still hard for him to fall asleep when they're together, especially if it isn't after a sweaty round of world-rocking sex. It's just that he can't get over the feeling of Finn under his fingertips, of Finn's mouth on his forehead, of Finn's whole body holding him, protecting him. He wishes he had a barrel full of vitamin D - that way he could stay up all night, just feeling Finn, never falling asleep, never forgetting for one moment the incredible bout of good luck he had.
He doesn't want to let down his guard. He really doesn't. Doesn't want to blink once and miss his chance of stopping Finn from leaving. But Finn is so warm and welcoming all around Kurt, and before he knows it – yet still at least half an hour after Finn is well into la-la land – Kurt is asleep.
The next time it's a little better. Kurt doesn't kick him – but Finn can't summon up the mailman fast enough when he slips underneath the covers and realizes Kurt is buck-naked and already half hard from waiting for him.
His stepbrother manages to convince him that Finn coming his brains out in his cowboy boxers will supply Kurt with masturbatory material probably for the rest of his life, so that works out.
They learn to compromise. They are teenagers, after all, and in dire need of REM sleep. Finn will warn him beforehand whenever he feels this irresistible urge to cuddle the hell of his gorgeous stepbrother, and Kurt promises to keep his clothes on. Finn still isn't getting how the second part of the deal is in any way cool, but he doesn't argue much when Kurt is snoring softly against his shoulder, his thigh snug between Finn's legs. That is tortuous in that slow-building kind, but Finn does a lot of heavy breathing through his nose whenever Kurt shifts and that works too. He clasps his hand over Kurt's own where it rests on his stomach, even though he knows he'll inevitably wake up sideways on the bed with Kurt's feet on either side of his head, and Kurt's breath tickling at his ankle.
He never remembers going to sleep.
