For Keith’s birthday. #sheith (tags: oral, rimming, #nsfw)

The party runs late but Keith doesn’t mind. He’s had a drink and a too-sugary piece of cake, and he’s feeling a little sentimental. It’s just nice, to be here with all his friends, the war behind them.

Nicer still that it’s winding down and Shiro’s sliding a hand around his hip and pulling him away. There’s a kiss to his cheek and then his neck and a breathy whisper of his name.

It’s not hard to guess where Shiro’s head is at. And Keith wants.

They start kissing halfway down the hall, laughing into each other’s mouths as their clumsy bodies collide and they nearly trip.

When Shiro pulls back its with a sliver smile, “Bed,” he says when he avoids Keith’s kiss, “I’ve still got a present for you.”

Keith wishes he could be contrary, but Shiro’s energy is infectious. “Another gift?”

The new hoverbike is still in the hanger, more than enough for one birthday. More than Keith ever would have dreamed up.

Shiro’s smile is secretive as he palms the door to key them in.

Keith knows it’s a sex surprise, but he still waits for Shiro to lead him into their bedroom and then turn to kiss him.

He still tastes of peaches from the drink and strawberries from the cake. Even if they just did this all night it would be enough. It’s Shiro.

“Ready for your gift?” Shiro croons as be lifts Keith’s shirt above his head and off.

“Mmm,” Keith hums at the pleasant way those strong hands slide back down his body. They’re confident and a little lewd as they touch him, trace him, skim down and begin to undo his pants.

“Whatever could the surprise be?” Keith wonders aloud as Shiro helps him out of the last of his clothes. He’s already hard.

Then Shiro is sitting him on the edge of their bed. “Do you want a hint?” Shiro’s eyes are dark and mischievous, his hands slide down to Keith’s knees.

Shiro pushes them apart and then lowers himself between them.

“I’m starting to get an idea,” Keith says breathless over the vision.

And it is a vision. He has to spread wide for Shiro’s shoulders, and it’s still barely enough. The man reaches for Keith’s cock, tilting it

toward him. Keith gasps, already too sensitive, too eager from the anticipation.

“I’m going to start,” shiro says, putting Keith’s cock to his lips. The wetness smears on the pink of his mouth and Keith has to swallow rough. “And then after you come,” the metal hand slides

down beneath Keith to touch his hole. “After you come, I’m going to eat you out until you come again. Until you come just from my tongue inside you. How does that sound baby? A good gift?”

Keith sucks in air and he feels woozy with it. With just Shiro’s words.

“Uh huh.”

There’s nothing else to say, so Shiro doesn’t. All at once he lowers his head and swallows Keith’s cock.

Keith gasps, clutching at the blankets. It’s good, so good. Shiro’s had months of practice on him and he’s a quick study, an excellent learner.

He takes Keith deep and filthy, using his hands and his tongue. He pauses at points to look up at Keith with those stunning eyes while Keith’s cock is tight in the back of his throat.

Keith can barely keep eye contact. It’s almost too much.

But he does because he wants to see. Because Shiro’s gorgeous and Keith knows he wants to be watched. Wants to see Keith lose it over this.

Not that he ever keeps it together. Not with Shiro.

So it’s not long at all before Shiro’s rhythm starts to ruin him.

At the edge he grabs at Shiro’s hair, the front bit that Shiro is always goading him to take but he’s too shy. This is his birthday, if he can’t be greedy when Shiro is serving it on a platter, when can he?

So he holds him and cries out as he comes. Shiro hums, pleased.

His orgasm is sweet and keith collapses back into the bed as Shiro swallows and pulls away.

“How’s that baby?”

Keith makes what he hopes is a sound of happiness. His mind is a white cloud, completely content.

“Ready for round two?”

Before Keith can gather words, Shiro is up and his hands wrap easily around Keith’s waist. From there it’s easy to maneuver him.

In seconds Keith is turned over and lying more in the center of their bed. He knows what comes next, and that Shiro hasn’t gotten off yet.

So he parts his legs and arches a little in what he hopes is an attractive shape.

From Shiro’s loud inhale, and the hands that slip down to grab at his ass, it works.

“Stars, you’re gorgeous.”

At that Keith is glad to be facing away so he can hide how the words get him.

He loves it even as it’s still uncomfortably new, even months in. Shiro /loves/ him, and he enjoys telling Keith in all ways in bed.

The hands roam across his ass, squeezing and playing with him. Then Keith feels the weight settle, feels Shiro pull him in and position him—

He squirms as Shiro bares him and tucks his head into the sheets.

“Ready?” There’s a kiss to the round of his ass and Shiro’s too-fond voice.

“Y—yeah,” Keith says even though he isn’t, could never be.

His nerves haven’t settled from the first round, so when Shiro bites then at his inner thigh, Keith jumps. Shiro laughs.

He opens his mouth to say something smart in return, but never gets the chance. Shiro’s hand pull him the rest of the way and his mouth—

Keith makes a sound at the first touch. It registers too intensely and he already knows it’s going to be bad, in the best kind of way.

Sure enough Shiro doesn’t hold back. He gives no quarter for the fact that’s Keith’s /just/ come. No, he just gets his tongue in Keith and

goes to town.

Keith’s helpless in it. He cries and clutches at the bedding, and even as the intensity rises, he doesn’t call for it to end.

His body moves and writhes against it, but Shiro’s no stranger to him, so he holds Keith right, and keeps him just where he wants him.

Shiro licks and sucks at him like he can’t get enough. Like he’s content to just stay there forever.

And Keith— Keith can’t /breathe/. He’s never come without direct stimulation, and they’ve tried. They have.

But it’s never been this dedicated.

It goes on and on until Keith is sweating and his eyes are teary from the intensity of it. It’s in turns so good and too much, and Keith never wants it to end.

It’s getting sloppy as Shiro eats him out, and Keith can /hear it/. It’s filthy, but it only helps.

His cock is hard again and dripping, but every time he tries to get friction, to get his hips against the sheets, Shiro pulls him back up, slips his tongue into him deeper.

It’s a tease and a torture. “Please,” Keith gasps at once point, the word slurring.

But Shiro doesn’t relent and Keith can feel his huge hands holding him, keeping him there as long as it takes.

It pushes Keith out of his head, and he smears nonsense words and sounds. He begs but he doesn’t know for what. He can’t even /think/.

And then impossibly, impossibly, the heat spikes in him. The pressure builds. Shiro is deep in him and it’s surrounding, encompassing, rolling over him like a wave.

“Shh— Ah—!” It’s a near scream and he’s so tense but Shiro doesn’t stop, doesn’t let up at all—

Then Keith is coming, shredding the sheets beneath him as he moans & grinds himself on Shiro’s tongue. His cock pulses & it feels amazing & strange to have nothing to rut against.

Shiro keeps his tongue inside him though and it makes his orgasm last, it feels ridiculously good.

When Shiro does eventually pull back, it’s like Keith’s strings have all been cut. He collapses down into the bedding, smearing his own mess into his belly.

He couldn’t give a single fuck about that though.

Shiro kisses his behind and then his lower back and spine.

“How was that sweetheart?” He mumbles into Keith’s ear when he gets to it.

Keith grunts into the sheets and then turns his head to get a breath of air. “Uh huh.” His throat is a desert.

Shiro laughs and kisses his hair.

It’s then that Keith registers Shiro’s cock, heavy against his ass as Shiro leans down into him.

“So I’m going to go brush my teeth,” Shiro says. “And then, birthday boy, you’re going to tell me what you want to do with this.”

There’s a slow, dirty grind of his cock against Keith’s ass before he’s getting up and heading to the bathroom.

Keith swears as he watches Shiro leave, his mind reeling with possibilities.

“Good present!” He shouts as the water turns on. There’s an affection laugh from Shiro.

Keith’s heart feels fit to burst. It’s all good, so good, and it’s all his. He grins stupidly into the sheets, happy for once to be another year older.
