They actually managed to pick up their clothes and drag themselves up to Blaine's room before anything else happened. Blaine felt sleepy and warm and wanted nothing more than to just fall asleep in Kurt's arms. That was, until Kurt bent over slightly to put down their - by now neatly folded - clothes on the armchair by the bed. The sight of Kurt's naked, glorious ass reminded him of all the things he'd thought of doing to his boyfriend in the car and he was instantly awake again.

Before he'd even consciously decided to do anything he was across the room and pulled Kurt's back flush against his chest, pressing his half-hard cock against that silky skin, breathing into Kurt's ear.

"The things I want to do to you right now... That ass shouldn't be legal."

Kurt giggled breathlessly, pressing back against Blaine, barely suppressing another moan. "And what do you want to do to my illegally fantastic ass?" he murmured into Blaine's neck, letting his tongue trace a tendon.

"Hmm..." Blaine growled, his hand slowly caressing Kurt's chest before going lower and lower until he stopped inches from Kurt's hard cock. "I can think of quite a few things. Like my tongue in your ass. You know what that does to you."

Kurt's reaction was predictable, but it never failed to drive Blaine mad with desire. The shiver that ran up his spine, that delicious moan and the way he rubbed that perfect ass against Blaine's erection... It never got old and it always made him weak in the knees.

Without further hesitation they stumbled over to the bed. Kurt was on his belly, legs spread wide open and ass up in the air before Blaine could get the lube out of the drawer. He took a few seconds to appreciate the gorgeous sight in front of him, only crawling between his lover's legs when Kurt started to writhe impatiently on the covers.

"Now who's impatient, baby?" he teased, smirking as his fingers traced the perfect curve of Kurt's ass, stroking at the sensitive skin on the inside of his thighs until he got the shiver he'd waited for.

"Blaine!" Kurt whined, the sound high and needy and sending even more blood rushing to Blaine's cock. He chuckled, gently pressing his thumb against Kurt's hole.

"Shhh. Let me take care of you, baby," he whispered into the soft skin of Kurt's lower back, applying a bit more pressure and pressing a gentle kiss to the right cheek. Kurt moaned at the dry friction and pressed back against Blaine's hand but kept still otherwise.

Blaine waited a few seconds to make sure Kurt wouldn't move too much, then leaned in and replaced his thumb with his tongue, slowly licking along the crack before circling around the rim. He kept the touch light, the tip of his tongue barely grazing skin. The sounds Kurt made went straight to his cock and after a few minutes of teasing that felt like an eternity, his licks became broader, more daring, the circles around the rim tighter and tighter.

He couldn't resist any longer when Kurt started to buck up against his face, slowly pushing his tongue in, enjoying the heat and the tight pressure and the way Kurt moaned loudly, all inhibition long forgotten. Blaine knew this was a major turn-on for Kurt and he was more than determined to make him come again just like this, no hands on his cock and no fingers involved.

Still moving his tongue around deliberately, Blaine tightened his grip on Kurt's cheeks, spreading them further apart, pressing his thumbs into the soft skin until he was sure to leave a bruise. Kurt positively screamed and Blaine knew this wouldn't last much longer. He pushed his tongue in as far as possible, pressing his face as close to Kurt as he could while still getting a minimal amount of oxygen, greedily licking inside of him.

Kurt pushed his ass back onto Blaine's tongue, muttering an incoherent string of 'oh my God yes, Blaine, more' and 'I love you' and 'gonna come' and 'please'. Taking a deep breath, Blaine pressed even closer, his tongue as deep into Kurt's ass as physically possible, twisting it the way he knew Kurt never failed to react to. And he wasn't disappointed. Kurt practically shouted his name and Blaine couldn't help but moan into him, the vibrations finally sending Kurt over the edge as he came with a long litany of 'Blaine, Blaine, yes, love you' on his lips.

It took nothing more than a few quick strokes and Blaine followed him, moaning wantonly into Kurt, tongue finally stilling. They collapsed onto the mattress, Blaine trying not to suffocate Kurt without having to roll off of him.

"Blaine," Kurt whined, voice still a bit raspy as he had barely come down from his high just yet.

"Hmm?" Blaine mumbled in response, burying his face in Kurt's neck.

"Could you please roll to the side? I'm kind of lying in a cooling puddle of come and it's not really comfortable. Also, you're sort of dead weight right now."
Reluctantly, Blaine moved so he was lying next to Kurt instead of on top of him, groaning in protest. He blindly grabbed for the tissues on Kurt's nightstand, roughly cleaning them up before falling back into the mattress, pulling Kurt close in the process. Sighing softly, Kurt snuggled up to him, his head on Blaine's chest.

Before they could fall asleep though, Blaine's foot caught on the untouched bottle of lube, reminding him that they weren't done for the day. Nowhere near done, even. With a smirk, he turned his eyes back to Kurt, knowing full well how to best keep him from falling asleep on him.
