This was my prompt, in these exact words, from my dear friend Haylee: WRITE ONE WHERE THEY HAVE SEX A BUNCH AND KIRK IS REALLY LOUD AND SPOCK IS JUST REALLY QUIET AND THEN WILL ONLY SPEAK WHEN HE'S ABOUT TO ORGASM BUT LIKE HE'LL ONLY SAY "I am near ejaculation. Is this suitable?" AND KIRK IS JUST LIKE "FUCK MEEEEMEMEMEMEME HARDEJRBTRBERG OH MAN SPOCK DICK OH YESAH FFGGU" AND THEN THEY KEEP HAVING SEX AND SPOCK IS JUST REALLY FORMAL AND THEN KIRK IS LIKE I AM TIRED OF THIS BS AND SO HE IS LIKE I AM GONNA FUCK YOU AND HE DOES AND SPOCK LIKE COMES UNDONE. OH MAN.

No set timeline except for reboot, probably post Into Darkness. Also established relationship huzzah. Before you ask, I did a fuckton of research on the fanon idea for Spock's dick okay. It was important. I know there's tons of speculation and all that good stuff, but let's go with almost 50 years of fandom, and adapt the whole "double-ridged' and "green" thing okay.

Set for seven parts in total.


The first time they have sex it's born out of a lot of pent-up sexual frustration.

James T. Kirk is the living, breathing, embodiment of /sexual frustration/ and has this talent where he can pretty much ignite it in anybody who walks past (except for Bones, but that's a whole other story.) Hell, he can even manage to get it out of /Spock/ if he tries hard enough, and that's saying something, considering the half-Vulcan is about as celibate as half-Vulcans can be. Kirk doesn't know jack squat about pon-farr other than Spock's whole seven year cycle isn't exactly approaching (yet, but Kirk's been thinking about making a calendar ever since he was rightfully informed), but he has seen Spock naked plenty of times and, as Chekov would say, Kirk could certainly do /zat/.

Of course, getting the guy to actually engage in the act is about as easy as balancing a spoon on your nose, and if you can do that, Kirk hates you. He really does. (Also, please teach him because he owes Bones some cash regarding that particular skill.) Of course Kirk's tried it, he's fucking James Tiberius Kirk for crying out loud, but /noo/, Spock's gotta be all "Perhaps we should wait until we've progressed further into our relationship, as it is customary" and all that other nonsense that Kirk basically takes as a straight up /no/. That's fine, it's all good, he's just biding his time. But he'll be damned if he's waiting for Spock's next pon-farr to kick in. A guy has his limits you know.

Of course, then one day out of the blue after a particular blow-out on the bridge where Spock and KIrk disagreed over something, as they tend to do, Spock's dragging Kirk into the elevator and shoving him up against the wall and kissing him in a way that he had to have learned from Kirk because Kirk's pretty fucking sure he's the only one with those kinds of skills. Spock has enough since to put the damn thing on emergency stop, because with their luck, some ensign would come stumbling in (it's happened before. Pavel Chekov will never be the same.) to see Kirk all laid out like a whore (nothing against them, no-slut shaming in Jim Kirk's book) against the wall with a half-Vulcan's tongue down his throat. Okay, so maybe it's not down his throat, just dragging across his own, and his teeth, and pretty much tasting everything that Kirk's mouth has to offer. For the first time all day he regrets that leftover Russian cuisine he scarfed down for lunch. Coming from a planet with limited oxygen, Spock's got about the greatest lung capacity of anyone Kirk's ever met, and so when they finally break apart, he just looks at Kirk as calm as ever.

"Are you done?" Kirk bites out between ragged gaps for air that feel pathetic when you're faced with an even-breathing alien. His mouth practically hurts and his face is burning and flushed and he swears to fucking God, Spock looks at him and /smirks/, the bastard. And Kirk's not about to have any of that, no sir-ee, so it's him who drags their mouths back together, hot and vivacious and it's practically /bruising/, really. Spock even does this thing where he catches Kirk's bottom lip between his teeth, and fuck, if that isn't Kirk's favourite thing in the world. He lets out a noise that doesn't sound human in the slightest, and even he's a little concerned by that, but then Spock's hands fall to his sides, gripping the fabric of his uniform shirt and he pretty much forgets what spawned this whole thing in the first place.

Spock doesn't say a word, which drives Kirk fucking crazy, just lets his palms travel under Kirk's shirt and along the counters of his chest and fucking watches his face of all things. It's like the pointy-eared bastard gets off on watching Kirk fall apart which is fucking ridiculous because they're pants are still on, and if Kirk isn't the biggest teenager you've ever met, than Bones is a bricklayer. Kirk can't say much about that, to be honest, because he's pretty sure he could get off on watching Spock the same way, but there's a huge difference between Jim Kirk and Spock.

"It would be logical if you kept the moaning to a minimum," Spock says in a low voice and if Kirk wasn't sporting the biggest hard-on he's ever had he'd probably strangle the guy. "The rest of the crew is still on the bridge, Captain." He draws out the last word, Captain, slowly and with a glint of something in his dark eyes and Kirk is pretty much hating himself because he knows he's the one who taught Spock these blasted things. His hands flutter usefully at his sides for a moment before he gives up and pulls Spock closer to him because if they're gonna do whatever it is their doing Kirk's not gonna flop around like a beached fish for it.

He also makes a point of making a very exaggerated noise that makes Spock's eyes grow a little, and then a little more when Kirk does the very whore-ish thing by grinding his hips into Spock's and though Kirk's aware that if he keeps it up he'll come in his pants like a God damn sixteen-year-old and this is the /second/ time he's reminded himself that he's a teenager. Good job, Kirk.

But the friction is too blissful to pass up and Jesus, he could use with a little more of that, so he doesn't hesitate in pushing fabric out of the way of his own cock and more or less giving Spock some hurry-up motions because it's fucking cold in this damn compartment. Spock of course is languid in his movements in a way that only Spock can be, and it's then that Kirk realizes that Spock's pretty much got full control of him in every way, and /fuck/ if that isn't the biggest turn-on ever. Kirk, of course, is glad to see Spock flushed of his own accord, considering he's so fucking calm and not in any way acting like they're screwing around with nothing but a pair of doors separating them and the rest of the crew. (Also, the first time that Kirk made the connection that Spock's blood was /green/ for crying out-loud, he sang "Spock's got a celery cock" for three whole minutes. In his defense, he was drunk, but Bones laughed so hard he nearly wet himself so there's that.)

The added friction is ten times better than Kirk could've probably dreamed (and trust him, he has) just flesh on flesh, and so maybe Kirk adds a spit-slicked hand for good measure because if this is their first fucking time he's going to do it /properly/. And that includes incredibly loud grunts and moans and he even throws in a yelled out "Spock!" when he feels himself teetering on that very refined edge, because he has a knack for scarring the entirety of the USS Enterprise.

Perhaps the best (or worst, if you're picky) of the whole ordeal is Spock saying, completely deadpan, "I am near ejaculation. Is this suitable?". What's even more messed up, is that that's what pushes Kirk over the edge and he's coming all over the place, torn between laughing and yelling until his throat is hoarse.

Spock follows suit, quickly, in fact, coming into Kirk's hands with little more than a soft noise that Kirk would've missed if he hadn't been on the lookout for it. He doesn't even blink a fucking eye, the dick, and instead steps back and adjusts himself, magically producing some sort of clean-up cloth like he fully expected this. The damn bastard /planned/ Kirk realises with a disgruntled noise, and he'd kiss the fuck out of him if he wasn't so pissed off at the idea. Pissed off because he's impressed, and that's just all kinds of wrong, even for Jim Kirk.

After several stretches of silence and adjusting themselves so they at least look presentable enough to step out on the bridge (Kirk's already rearranging his features into a carefully placed smirk), Spock reaches over and curls two of his fingers around two of Kirk's, and the move is strangely intimate and sends chills skittering up Kirk's spine.

Like he said. Teenager.

Kirk takes great satisfaction in looking at the wide-eyed, open-mouthed, flushed-red faces of his crew when the doors slide open.
