Summary: The first time Kurt goes down on Blaine
Words: 2700
Spoilers: None

The first time Kurt goes down on Blaine it is a bit of a disaster. Just a little bit. Blaine's done it to Kurt three times and Kurt is fully aware of how fantastic it feels but always blushes afterwards because when he remembers being spread out over his bed (or that one time pressed up against his door with Blaine literally on his knees) he remembers that he was naked (mostly) and arching and making embarrassing sounds and probably even more embarrassing faces.

Afterwards Blaine always chuckles and tells him he's beautiful and that he loves him and that one day Kurt will believe him. Kurt really, really hopes so. He's not so self-conscious about his looks, about being naked, about sex, as he was. But he still blushes strawberry red all the goddamn time.

He blushes strawberry red when he tells Blaine with his lips against Blaine's neck that he wants to blow him. But Blaine nods fervently and garbles something out and kisses him hard. When he pulls back he looks Kurt in the eye and says, "You don't have to. Just because I've gone down on you, there's no pressure."

There is, of course there is: to return the favor. But also, Kurt wants to. So Kurt pushes him back onto the bed and straddles his hips and kisses him again. He keeps kissing him and pressing his hips down against him until he's fuzzy with lust and hopes Blaine is too and then he slides down to kneel between his legs and start undoing his trousers.

Above him, Blaine twists across the sheets, his hands grabbing at the duvet and his head turning into the pillow to muffle a moan as Kurt's hands get rough and press into the bulge of his pants. He's turned on and Kurt loves it. He especially loves that from here he can watch it happen because the lights in the room are still on and his boyfriend's shirtless and for once he isn't pressing down hard against him.

God Blaine's perfect.

Kurt pulls the zipper down with too much force and comes close to breaking the cotton that holds the crotch together. He yanks and then realizes those pants aren't coming off with him crouched between Blaine's legs but maybe that's okay and, oh god, he's nervous now.

They're always in the dark. Or at least the shadows. Or at least with their eyes shut. When Blaine does this to him, Kurt keeps his eyes shut. He stares up and, indeed, Blaine's eyelashes are curved low over his cheeks and he's breathing hard.

He's never even taken the time to look at Blaine's cock. Not properly, not like this encounter is about to afford him. It's always just been rubbing and pressing and hands. He knows the weight of it in his palm, but not the color. And certainly not the taste.

He's nervous and unsure. And, shit, what if he's really, really bad at this? What if he's so bad, Blaine opens his eyes and pushes him off and has to tell his how to do it properly?

Kurt's got Blaine's pants down to midthigh where they're stretched tight and pressing into the skin because Blaine's spreading his legs and arching up and whining.

Kurt's not even touching him so he does, laying his hands on the exposed flesh between the tight grey boxer briefs and Blaine's pants. His thumbs caress back and forth and Blaine bucks and Kurt wants, even if he's terrified.

Oh, for fuck's sakes, he thinks to himself, almost rolling his eyes as he feels his tongue slide across his lips of it's own volition, his eyes narrowing to the outline of Blaine hard under the cotton.

He looks big. Really big. Kurt's got a big mouth, Finn's teased him about it when he sings enough for Kurt to have stretched it as wide as it'll go when he looks in the mirror. Sure, he's thought about taking a whole lot of cock between his lips, down his throat. He's gotten off to that. But this is different.

Come on.

Kurt's fingers slide beneath the waistband and yank at Blaine's underwear, pulling them down and letting them hold tight beneath his balls and Kurt's just staring. He knows that, has a split second to wonder how weird he is to be captivated by a fucking cock before he just goes right back to staring.

Blaine's hard and jutting and there's a bob coinciding with the fast shift of Blaine's diaphragm as he breathes. His cock curves just slightly up, towards his belly button and there's slickness at the head.

He's big and hard and a little big shorter than Kurt's (but then Kurt's kind of on the large side, he knows that) but maybe thicker. And darker. And there's more hair. Denser. At the base.

Why is that so hot?

And veins. Kurt's always prided himself (in some bizarre, unjustified way) on having a smooth, rosy pink cock. But Blaine's is stained darker and there are tracks of almost purple-blue running up the underside. They look contoured, like they'd feel almost rough against Kurt's tongue. Like they'd pulse along with Blaine's heartbeat.

Kurt has to swallow because otherwise the saliva across his tongue is sure to start leaking out the corners of his mouth. This is terrifying. How is it all going to fit?

He's brought back to reality (away from that nice place in his mind where Blaine's cock isn't actually attached to Blaine and is something he might take home and study for a while) when Blaine moans out his name and rocks his hips up.

"Right," Kurt says, mostly to himself. His hands smooth up over the scrunched cotton to Blaine's hips and he holds him down, just like he'd planned in his head a million times. This couldn't be that hard. He just had to do exactly what the internet has taught him: lips over teeth, sink down, suck, lick on the way up and repeat. And hope he doesn't gag. That his jaw doesn't cramp. That Blaine doesn't get bored and start trying to fuck into his mouth.

Shit.

He looks up Blaine's body and again is utterly overwhelmed by how gloriously naked he is. How stretched out and lithe and contoured and dark this boy is under him.

Blaine's hands have stretched back and are grabbing at the pillow either side of his head and his eyes are still closed.

Here goes nothing then.

Kurt keeps repeating the instructions in his mind as he wraps a hand around the base and leaves his other hand pressing down hard against Blaine's hip. Blaine bucks and Kurt tries not to think about what will happen if he does that into Kurt's mouth.

He presses his lips to the head, trying out the smell and the heat of him and neither are disagreeable. He hasn't said it out loud but he likes the smell of Blaine where it's strongest. He doesn't know if it's sweat or pheromones or sex, perhaps it's all three, but he likes the smells Blaine makes. The concentrate of it all around Blaine's cock is intoxicating and the heat against his lips is nice.

Lips over teeth.

He slides down. Just an inch and lets his tongue slide over then around the head while Blaine's hips squirm under his forearm.

It's not unpleasant. He still has no idea how it's all going to fit but this is okay. The tip of his tongue finds the slit of Blaine's cock easily and it taste salty and bitter. It's not a taste he's instantly in love with but it doesn't make him gag like he'd almost expected. Pressing his tongue there makes Blaine moan loud and high and then gasp out his name ad that kind of makes the taste a little addictive.

He thinks this is how vodka works as well.

Another inch down and his tongue on the underside and he takes an experimental breath through his nose and finds that that's just fine. Lets the weight of Blaine's cock against his tongue press and the smell of sweat and Blaine and the taste of precome, he guesses, inundate him.

Just fine.

He still has no idea where the remaining inches are going to go.

Kurt looks up through his lashes for Blaine and can only see stretched out sweat-slicked skin and the angles of his jaw as he thrashes his head back into the pillows and moans again.

Kurt wonders if Blaine's exaggerating for his benefit or whether it's just because he's a performance-whore all and any day of the week.

Right: suck.

Kurt's cheeks hollow and he tries to convince his brain that the thing in his mouth is just a giant straw and that's the right suction, that's what the internet said. He sucks and breathes and tries to keep his lips tight as he pulls back, gasps around Blaine's cock and then sinks back down and sucks again.

Above him, Blaine's still moaning like he's dying and Kurt has half a mind to pull off and tell him to shut up because even though they have the house to themselves that's no excuse for Blaine to upset the neighbours and all the dogs on the street and act like a whore. He doesn't, he slides a little lower and sucks and tastes and arches to feel a frisson up his own spine because if he ignores the questions of:

How is it all going to fit?

and

What happens when I've been doing this for half an hour and my jaw cramps up?

Other than that he rather enjoys this.

Another suck and a little of his tongue up what he thinks must be one of those delicious looking veins, under the head and he licks up the slit: bitter again and Blaine's still feels achingly hard in his mouth: he considers that in and of itself an achievement.

A deep breath through his nose and he sucks three inches into his mouth, the hand around the base, squeezing with the motion and again he debates what on earth he's meant to do to keep this up because it's been all of thirty seconds and Blaine's just moaning and swearing under his breath.

Now above his breath, yelping out "Fuck" and then "Kurt" and then "OhMyGodShitFuckI'mSoSorry!" and his hands are in Kurt's hair and are tight and pulling and harsh and Not Good For The Roots and Kurt's pulled off and away and What the fuck? But something warm and wet hits his chin and Kurt's eyes go wide as Blaine's hips rocket up off the bed and his forearm goes with them, no match for the kinetic energy and Kurt stares, absolutely stares, as Blaine's cock, his hand still wrapped around the base, pulses—fucking pulses—and spurts another line of cum up Blaine's stomach. Then another, less powerful and falling down across the dark hair. Then more but just leaking out and down and over Kurt's fingers and—

Holy Shit.

Blaine's hips fall back onto the bed and he's limp and sated and Kurt's hand unwraps, a finger at a time, from Blaine's cock so it can flop forward into the come on his stomach and instantly start to soften. It's still insanely hot to look at and Kurt has to, for some reason, divert his eyes.

Oh. So that's how it goes, then.

He watches the rise and fall of Blaine's belly (still come streaked) even out and slow and only after a full minute has passed does he let his eyes stray up, over Blaine's chest to his pursed lips and the arm Blaine's thrown across his eyes and the deep red blush high on his cheeks.

Oh.

Not a performance-whore then. Kurt can't help the straightening of his back and the grin that settles on his lips when he realizes just how fast and hard Blaine had gotten off on that. And Kurt's still hard in his pants. Hard and he's pretty sure desperate.

Shifting up, not quite sure what to do with Blaine's softening cock and all the come, Kurt watches him closely as he wonders where to put his wet hand. He kind of…

He raises it quickly to his lips and licks and he's tasted his own come before, for sure, and it was kind of gross but not terrible. This is…it tastes the same, mostly, but it's not even a little bit gross.

He's upset for a moment that Blaine pulled him away at the last minute. He thinks wistfully, Next time, and then he looks back to Blaine who's gone a little too still and is still hiding behind his forearm. Kurt leans up, he doesn't mean to press close, but it's kind of unavoidable and Blaine shivers at the contact between them.

Kurt's hand wraps around his wrist and pull his arm away, staring at him with bright eyes and a smile. "Hey," he says.

Blaine stares and Kurt can't guess at all what's he's thinking. Then he says, "Hey," and then, "I'm sorry." There's a pause and Kurt doesn't say anything because he doesn't know what or how to say it and then Blaine keeps going: "Oh my god, I am so sorry. I didn't realize it felt like that. I didn't mean to…I'd last longer if…Oh god, it's on your…"

Blaine reaches up and his fingers run under Kurt's chin and Kurt can't help but tilt his head and nuzzle into it like a cat except it's slippery and that's Blaine's come and it makes him whimper.

Oh he likes that.

Blaine, somehow, doesn't notice, and just draws his fingers away and then slides up to reach for a tissue. Kurt pushes the mental image helpfully provided to him of Blaine sliding his fingers inside Kurt's mouth and leaving them there until they're licked clean.

Blaine keeps cleaning himself up. His hands shaking and his eyes flickering as he mumbles under his breath and Kurt just stares. Blaine pulls his underwear back up and then his trousers and Kurt guesses there won't be any mostly-naked cuddling afterwards tonight. "I'm really, truly, so, so sorry, Kurt. I can't believe I…" Blaine trails off.

But Kurt pushes, like he so often does: "Sorry what?"

Blaine stares. "I didn't realize I'd get off that fast."

"You're sorry you didn't realize?" Kurt's hand has fallen to his own crotch and is pressing down half-hoping Blaine won't notice but half-hoping he really, really will. "Or sorry you were so fast? Or sorry you almost came in my mouth?"

Blaine stares and his eyes flicker down to Kurt's hand. "All of them?" he tries.

Kurt sighs and nudges him in the shoulder before he falls beside him, on his back and stretching his legs and feeling more bold and more powerful than he has in forever.

So that's what giving a blowjob is like. It's not long or difficult or gross.

With Blaine it's entirely the opposite.

Except Kurt kind of wants more. Even if Blaine doesn't.

He lies back and hums at Blaine and Blaine's entirely content to slide his hand down Kurt's naked chest and set to work on his pants. This will be relatively quick and relatively easy. Mouths pressed and eyes closed the whole time while Blaine's hand works in concert with Kurt's to get him off.

They'll whine together and Kurt while mumble Blaine's name against his lips when he comes. They'll fall back and snuggle just a little in their jeans and Blaine will apologise again and Kurt will shake his head and let a thousand thoughts flood his mind but just mumble back that it was fine. Because it was.

It so was.

I think there will probably be a follow up piece to this one. Just so you all know to keep an eye out!
