The Academy AU for sensors

[smartass_captain]

The night Sam Kirk walks into the Kirk family farmhouse his little brother throws a fucking beer bottle at his face. He misses. If he'd hit, the next several years might not have happened.



Jim is twenty years old and his life is a fucking mess.

He's no longer in the goddamn hospital every other month, but still in mandatory therapy until he ages out of the system on his 21st birthday. His therapist has worked with him since. Well. Since he got mandated one by the University of Iowa's children's hospital when they brought him home and nursed him back from the brink of being starved to death. Sam isn't here about Tarsus though. He's here because he heard little Jimmy just got out of a stint in county for petty theft.

Why's a guy stealing bread in this day and age? Jim doesn't give him a satisfactory answer. He can't. There isn't one. He'd been better until he'd left his personal device at home for a weekend boke trip. Without his meal schedule Jim can't function. But see, his body doesn't tell him when he's hungry anymore either, so Jim hadn't noticed until it was day three and he started hurting. All sense left him. Next thing he knows he's sitting in a jail cell being watched while he eats the food they gave him because anyone can see Jim Kirk is still too thin. Jim hates it. That look of fucking pity.

He was home and on his fourth beer of the evening when his fucking older brother strides in like he hasn't been gone for the last damn near decade of Jim's life.

"Sober up. I want you to come into town with me tomorrow and take a test." Sam had said. Jim thinks he told his brother to fuck off. He thinks he tried, but he might have stormed off so the other didn't see him break down into tears. He dodges Sam for three days before they bond over noon breakfast talking about when their mom finally found out about and ditched Frank. Sam asks where Winona sent him then, since neither of them believes for a second she stayed Earthside to raise him herself.

Jim lies.

But the lie works. And so he lets Sam drive them into town chattering the whole time about Starfleet. He wants Jim to take an aptitude test. If he passes, well. Dear ol' big brother's gonna whisk him away to San Francisco so they can enlist together. Sam got in, you see. Second attempt, so maybe Jimmy won't be going with him Right away.

"Jim." Jim corrects him. He's toying with the idea of maybe letting Sam talk him into this, but he's not forgetting the last damn near decade so easily. Not forgiving it yet, either. He tells himself he'll take the stupid test to shut his brother up. And hell, maybe he'll even beat his 'big bro' and pass on a first try. He aces it, hangover and all. Sam seems real keen on congratulating himself for giving Jim pointers the last couple days and Jim doesn't argue much.

A change of scenery seems like a decent idea.

All he wants to take fits into a single duffel bag he tosses into the back of Sam's beater of a truck and they make for San Francisco...

Jim stumbles back into Spock's personal space at the yank. His eyes are still on Sam Kirk, stunned and on the floor of his dorm gaping up at Jim as though he can't believe this just happened. Then they're out of the dorm and Jim has to face the music. Has to apologize to Spock that he hit the guy Spock's in love with and how he's sorry his brother's such an Asshole.

"Spock, Spock listen to me. I couldn't...I had to do it." Down the stairs. Every clomp of their boots feels twenty decibels louder than it should because Jim's afraid he's ruined his friendship. Only Spock turns, his gaze wild. Jim doesn't even get a chance to ask 'What?' before he's pinned to the wall. A cooler hand wrapping around all of Jim's fingers on his left hand and pinning it to the wall next to his head.

A mouth on his own. Pressing so hard Jim can feel the imprint of his own teeth on the soft inside of his lips. And it's everything he's wanted but also what is happening right now???

Jim.

His name in that timbre. Oh, fuck yes. That's the good shit.

"Y-yeah?" He's sucking in air. Is this actually happening right now? Oh, he wants to say. His mouth is open even. Only to be swallowed up by hungry lips once more. This time Jim leaves his lips parted. Invites Spock to explore his mouth with just the barest teasing flits of his tongue. Does he give a single fuck if they're in the stairwell of the dormitories? No he does not. He'd get on his knees right here if Spock wanted him to. What anyone else sees is their problem.

Only when Spock pulls back again does Jim let out a breathless chuckle, heavy with his own desire.

"F...friends, huh?"

[sensors]

Spock does not hear any of Kirk's—Jim's—attempted explanations on the stairs. He is too busy replaying the image of him striking Samuel Kirk for what he had said about Spock. For Spock's benefit.

At some point in the kiss, Spock ends up tangling their fingers obscenely there against the wall; it is fortunate that Spock is the only Vulcan currently on the campus. He is not thinking about that, however. He is far too busy with the moment, with tasting Jim's mouth, with pressing their bodies together tightly.

Only when he draws back for a breath and Jim speaks again does Spock have the grace to fluster somewhat, clearing his throat and reluctantly taking a half-step back, though the hand that had found its place at Jim's waist remains there.

"I did not indicate whether I was using the Terran or Vulcan definition," Spock explains, "and they are very different."

I swear this icon gets so much use

[smartass_captain]

Jim's got no idea why how the man holds his hand is weird in any way. Way Jim figures, it's just more comfortable to Spock that way, even if it presses his knuckles roughly against the wall. Jim couldn't care less. Not when he's taking in the heady kiss and soft sounds bubbling up between them.

Spock's pressed flush up against Jim, utterly pinning him to the wall. Jim can't help to be a little bit cheeky and rocks his hips up into Spock's own. Hisses triumphantly for the friction. Ah--too far. Spock pulls away. Jim whines a little in the back of his throat but doesn't chase him.

"They are?" Panting slightly. "You. Wanna head back to our room and maybe elucidate on th'differences?"

bless

[sensors]

It technically is the rolling of Jim's hips and the friction between them that urge Spock to shift. However, it is simply because if Spock does not pause now, they are not leaving this stairwell for the entirety of winter break.

Spock looks at Jim as he is, panting and eager, and nods sharply. He presses another hungry kiss to his mouth before finally drawing back properly, his grip on Jim's hand gentling at least for the rest of the trek downstairs to their floor and then through the corridor to their shared room.

They at least do not pass many people along the way, though there are a small number of them. However, Spock is single-minded, opening their door and ushering them both inside before letting it close behind them and tapping the lock.

[smartass_captain]

Yeah Jim would really appreciate some spinal support. Plus Spock would get cold! They can't have that. Better for all parties, especially cadets just trying to get to or from their rooms that these two trot downstairs looking quite intent on their destination.

Better they don't start their break getting written up for public indecency.

"Can't believe..." Jim still doesn't quite understand how they've ended up here like this. He's sputtering as Spock doesn't even turn to hit the lock. But this is a lot, it's fast, right? What do normal people do?? He blinks rapidly a couple times, really just trying to think with any part of him Not his dick for half a second. The grabbing of his hand comes to mind first. Spock's still holding onto his left, so Jim takes a step forward so he can lift it up between them.

He slips his eyes shut and kisses gently over the back of Spock's knuckles. Chaste, romantic--Jim hopes. Then peers up at the other.

"Hey~"

[sensors]

By the time they reach the room, Spock feels as though he has regained himself enough to have a proper conversation. He does!

Or, well, he does until Jim Kirk presses a kiss to his hand and Spock chokes on a breath, his eyes widening again. He tries to tell himself (over and over) that Terrans, humans especially, do not see hands the same way Vulcans do.

It does not help.

By the time Jim's eyes flutter open Spock is staring at him openly, his face flushed green all the way to the tips of his ears. His knuckles are still tingling and a warmth is coiling in his stomach.

Spock has never in his life been this flustered, much less so in front of Jim. But he clearly is, and in a positive way.

He clears his throat, trying to regain his composure. "Please elucidate on what you are struggling to believe."

Does that sound normal?

[smartass_captain]

Yeah Jim's got no damn clue that what he's doing is Very Much not chaste and romantic and suave like he thinks it is. That this is probably extremely intimate even if it's the back of the hand like this. What he does know is that Spock is blushing furiously when Jim peers up at him. He can't help his triumphant little grin to see it either. That's a stroke to the ego Jim didn't even know he needed right now.

"How long?" Jim asks, his smile widening when Spock fights to clear his throat. A beat, and if Spock doesn't look like he knows how to answer Jim will add,

"How long has it been me?"

[sensors]

Well, it is certainly a type of romantic. One Spock definitely enjoys, though he should likely explain the difference later.

However, the question gets Spock's more usual head tilt as he considers, and then:

"Twelve weeks, five days," with a pause to look at the clock, "sixteen hours and forty-nine minutes."

Which, for someone keeping track, like Spock, is about when Jim first managed to get Spock to go on a sort-of-maybe-kind-of-date to a Thai restaurant. The same one Spock brought food from when Jim was feeling low.

[smartass_captain]

"Twelve and a half weeks?!" Incredulous. Also, if he's rounding it ought to be closer to thirteen but semantics. That's practically the beginning of the term though! Before all the girls (blonde, blue eyed), before all the trouble Jim got into. Before Mitchell for damn certain. All that time?

"Spock I..." Jim squeezes their joined hands tighter. "I had no goddamn idea. I tried to get your attention for the entire first part of the term." Another half step closer so he's in the other's space again. "I wouldn't have looked anywhere else if I'd known--"

And suddenly Jim surges forward to wrap his free arm around Spock's broad shoulders. Jim presses a hungry kiss onto the other's lips again. Nips the man's bottom lip when he pulls away just enough to breathe, "Could have had this...so fucking long ago..."

[sensors]

Spock meets Jim's step closer with one of his own, leaving them practically toe to toe as he watches his face, searching his expression while he listens to what he has to say.

"I was not aware. When I had arrived on Earth it was just after—"

When Jim kisses him, Spock presses into it eagerly, open and hungry and wanting. The catch of Jim's blunted teeth manages to steal a quiet, wanting sound out of him, and then he breathes quietly, taking everything in. "I was not prepared for the depth of emotion I began to feel for you, and as the dissolution of my engagement was mere weeks before the start of term, I did not see myself as desirable."

Spock initiates another kiss, lingering, his free hand dropping to Jim's hip.

"I was unable to ascertain how someone as attractive, intelligent, and kind as you could be attracted to me."

[smartass_captain]

"As me. You're--Spock have you looked in a mirror?" Jim's free hand pulls back to grip one of Spock's shoulders hard and shakes him by it just a little. "You're sex on legs, I've never met anyone smarter than you in my life. You're funny and kind and--" He's sputtering a little.

"And I'm--" His voice wobbles then because Spock is calling Jim a whole lot of things he doesn't feel like he's earned.

It's for the best Spock cuts him off with another kiss. This one not as deep, but a testing of the waters. Lingering. Mapping out the shape of Jim's full lips with his own.

"....I want to have sex with you really bad right now....i-is the thing." Jim groans softly between them. "Wanna swallow you down, have you fuck my mouth...or ride you until you d-don't even know your name anymore...!" His fingers fist in the fabric of Spock's shirt. "And I know that's too f-fast, too much but...!"

[sensors]

"I do not understand the metaphor 'sex on legs.'" Spock is aware his curiosity is not helping anything, but he has to make that part known first.

After, when Jim is breathing words between them, Spock swallows. Normally he might have several questions, but he is able to glean meaning well enough from context that he simply inhales a little sharply and blinks both sets of eyelids before looking at him, hand lifting to close atop Jim's in his shirt.

He nudges their foreheads together gently; there is transference but it is steady and grounding. This is the most Spock has touched anyone other than regular contact with his mother as a child, and well, with T'Pring while they were still betrothed.

"We have established that we both have long-term affection and desire for one another," he begins reasonably, "and should you desire to wait, I will not push you. I have lived with you in this room for months with you almost entirely undressed at all times and have, as I have heard it colloquially put, 'survived.' I will not cease to do so should you want to progress more slowly. However, I will also note that my opinion of you will not change regardless of the speed or lack thereof and I hope yours of me would not either."

A beat passes.

"To clarify, I have desired to have sexual intercourse with you for some time now and continue to desire to."

At least they're both horny losers

[smartass_captain]

Jim feels his breath lodge in his throat. This is more than he deserves, more than he's worth. If this were just some stupid fling, Jim wouldn't care so goddamn much. Sex is sex, or so he thought. But it's not some fling with Spock. He's very much obsessed with the guy and has to live with him when this is all over. There is no sneaking out of the room when they're done and heading back to his room. There is no avoid a morning-after talk.

If Jim does this, it's going to Matter. The thought terrifies him. He's gonna fuck it up like he fucks Everything up.

But Spock's there, urging them together until their foreheads bump so gently and rest just so. It makes him feel better. Better able to breathe. So Jim listens. And then his breath leaks out of him in a desperate, needy rush at the last.

"I'll explain anything you want after if you touch me like you've wanted to right fucking now."

they're so stupid (fond)

[sensors]

It is certainly not some fling with Spock. For Spock, it is also not some fling with Jim. Spock has found is very bad at flings and did not desire one with Jim in the first place.

He is patient as Jim processes, as he comes to his decision.

His lips curve up slightly at the corners. Just a little. "I believe you will."

Then he unceremoniously picks Jim directly off the floor, hoists him over his shoulder, carts him over to one of the beds, and practically tosses him onto it. "You are overdressed."

A pointed statement as Spock starts to remove his own layers, still standing so as to get the robes off properly.

I love using his stupid icons so much

[smartass_captain]

For half a second, Jim just melts into Spock's touch to see that barely-there smile. Just because Vulcan expressions are subtle doesn't meant they're not there. It's so hot and Jim can't help the way his stomach flip-flops to see it. Just like he can't help the very undignified noise he makes that is dangerously close to a squeak to be hauled up off the floor as though he weighed nothing only to be practically thrown onto Spock's bed. "Shi--Spock!!" Oh yeah, he's moaning that right in a pointed ear.

"Holy...fucking shit..!" The words tremble out of Jim's mouth when he bounces once on the bed before he settles. "I-wh. I mean yeah. Yes. Hell yes. Big agree." How fast can Jim get out of his uniform? He's about to set a new record. His red jacket gets flung over to his own bed, but everything else kind of bunches where Jim deposits it right next to him, only to slither into a pile of fabric off the side of Spock's bed.

But at the last, Jim hooks his thumbs into his fitted underwear and peels it down off of him with a needy groan just to show off how goddamned hard he is already for Spock and his attention.

"Come here, c'mere I can get that off you just--"

they're REALLY good lmao

[sensors]

Spock has very little evidence of Jim's habits and mannerisms sexually as he has always ensured there was no overlap, and to say he is briefly startled by the intensity with which Jim responds to what Spock had found most practical would be correct.

That is not to say he dislikes it, however, as he briefly feels as though his mouth has gone dry from the sound of Jim moaning in his ear. Spock watches him the entire time as he undresses, gaze dark and hungry, and he's almost fully undressed by the time Jim tries to get him onto the bed and closer to him already: all he has left are his pants and underwear, and for once in his life Spock has not taken the time to fold any of it, just tossed it over the back of his desk chair.

Spock shifts close enough for Jim to get his hands on him, but he busies him instead with straddling his thighs and kissing him, harder than before, desperate and heated with a low groan against his mouth before he starts dragging his attentions lower, teeth catching briefly at his throat, his collarbone—

—his eyes flick up to look at his face, one eyebrow arched slightly, as he presses a kiss to the center of his chest in the same moment that one of his hands slides up the length of Jim's inner thigh.

[smartass_captain]

His hands Are on Spock immediately. The nanosecond Spock is in reach Jim's hands are at the waistline of Spock's pants, unfastening the hook and eye to uncover the practical slim zipper beneath with practiced fingers. Impatience is read in every tug of Jim's fingers, in the heavy breath that shakes its way out of Jim's lungs the first Spock plants a knee on the bed. There's barely enough room for both of them on just Spock's bed.

Then Spock's bent over him, that perfect arch of a back in reach for Jim to map his hands across. The blue is nearly chased from his eyes as he presses up into that hungry kiss. Ready and willing to pull out every trick and move Jim's got if it's for Spock's pleasure.

That deep voice vibrates against Jim's chest. He's panting for air when Spock begins exploring with his mouth. Bucking his hips desperately with each sharp nip at his throat. Catching at his collar.

"Fuck oh fuck that's good, that's so damn good--" There's no filter on the words tumbling out of Jim's mouth. He can't ever remember being this keyed up in his goddamn life. And here Spock will get his first experience with intercourse where human males are concerned. Not nearly as wet as he would have expected.

And Jim, misinterpreting that curious touch, flails one hand to point to the foot of his bed.

"F..foot locker. S-should be plenty of lube in there, and a whole bunch of toys I can explain how to use later."

[sensors]

Jim's hands practically feel as though they burn his skin for the body heat difference and Spock swallows hard. He has never been this easily affected with any of his previous human partners, but perhaps it is the affection making it that much more intense.

Perhaps it is also the desperation Jim already showcases with each thing Spock does; he has also never felt this wanted before and he desperately, desperately craves more of it.

Spock has at least been somewhat sexually adventurous, though with less overall partners than Jim may have had. He is aware of the usage of and requirement for lubricant with humans for certain aspects, though Vulcans produce enough of their own, generally speaking. Spock considers mentioning so, as he is aware that the preparation for anal sex is similar both between species and sexes, but curiosity about the rest of Jim's comment wins out and he slides just far enough away to get to said foot locker and pop it open, arching an eyebrow slightly as he skates a glance over everything inside before he grabs the bottle of lubricant and returns to his own bed and Jim himself.

He sets the bottle on the bed and slides up Jim's body again to press a kiss to his mouth; as he does he shoves his pants and underwear the rest of the way down his hips and gets them off his legs, leaving them in similar states of undress.

Similar states of hardness too, though their anatomy does have certain differences, namely the fact that Spock's arousal has slipped free of its normal sheathed housing and that said sheath has leaked enough slick that not only is his cock coated, his inner thighs are dripping obscenely.

He has never been this aroused in his life, he realizes, though he does not say as much because he's too busy pinning Jim to the bed with his own body to grind their hips together, giving them both slippery friction that drags a groan from low in his chest.

[smartass_captain]

Jim Kirk. Spread out on Spock's bed like he belongs there. Sunk into the pillow, his legs splayed to welcome Spock between them, cock stiff and eager. He makes an obscene picture laying there with that ruddy flush to his cheeks and down his neck.

"Yeah, there you go. Wanna see you--"

One thing to read up on Vulcan anatomy out of curiosity months ago. Another to see Spock hard and dripping because of him. Jim won't get the chance to smart off. All that comes out of his parted lips is a shocked moan. His back arches off the bed, eager to meet Spock's hungry roll of his hips

"Y'feel that?" Jim murmurs against his partner's lips. His hips roll up and rock against Spock's so good he has to hiss. "That's all for you. You're the most attractive fucking person I've e-ever met. Want you to rail me into the mattress, want to fuck you on every surface we have in here. In the library, on the simulated bridge--" Cut off by another moan that rips itself from his throat.

"I've wanted you so goddamn bad practically since the day we met and it only got worse when I got to know you, Spock."

[sensors]

Now that they are urged together like this, it becomes easier to use his hands for other things but more difficult to keep his thoughts in order. As Jim arches and rocks up against him Spock meets him movement for movement, one hand splayed on the sheets as the other slides down Jim's arm, to his wrist, fingertips tracing over his knuckles.

The sound he lets out into Jim's mouth is frankly obscene and he has to take a moment to catch his breath, eyes dark from how blown his pupils are as he looks down at him, processing what Jim said to him. Then his head pops up a little bit like a meerkat or something and he says—

"—If you desire to have sexual intercourse while seated in the Captain's chair, we will be required to find the means and time to do so while we are still cadets as it is unlikely we will be able to do so once we are stationed on a ship. The suggestion of making use of the simulated bridge is prudent." He is already going through some calculations in his head, and his access to areas of the academy—the library is simple, for example.

Each word is throaty despite their matter-of-fact nature and he continues on to nod, kissing him eagerly before he speaks again. "I have never desired anyone as much as I do you, and it has been this way from the moment I realized I did so at all."

Finally, finally, he stops fondling Jim's hand to slide his between them, long fingers curling around both of their cocks at once to stroke them together. "I have dreamed of you when I took time to sleep," he adds, sounding almost thoughtful. "It does not compare to the reality."

[smartass_captain]

That's about the Only things Spock could have said that would make Jim throw the brakes on this to catch his breath a little.

"Holy shit..." Something feverish and manic alights in his blue eyes. Jim frames Spock's cheeks in his free hand and surges up to press a kiss against his lips. "Fuck yes. We Have to find a way to make that happen now. God that would be so hot--"

His mischievous chuckles trail off into another breathy gasp. His touch drags down Spock's shoulder, his arm. Both arms, once Spock's freed his hand. Jim arches his hips. Too greedy not to try and fuck into the loose fist Spock is making around them both.

"Oh yeah--me too. I couldn't stop thinking of you even when I was...trying to..."

Everyone he'd been with this whole term had been little more than a distraction. A salve to soothe him from not having the man settled over him now. It hadn't worked. Not even a little bit.

"What's your favorite dream of m...me..?" Breathed out around a wicked grin.

[sensors]

While Spock does not grin in return, the slight tip of his head is as good as doing so, for him, the way his mouth briefly ticks up at one corner even as they kiss.

He keeps his hand on them, periodically looking down at the sight and swallowing hard from just how evocative—he needs to focus.

"I am granted access to areas of the campus after hours as my sleep schedule is much shorter than other species and I require more productive time." A beat passes and he shifts the angle of his wrist just enough to let Jim fuck into the grasp of his hand, tipping his head down to murmur into his ear.

"There is a particular one in which we are having sexual intercourse while seated in the Captain's chair." Alright, maybe his tone is a little wry to make up for the fact that he had briefly pretended he was very much planning to do Jim a favor with the setup when he has also had it on his mind and also worded it exactly the same as he did just a moment ago. "However, I have found them all markedly enjoyable. I would find it gratifying to be able to show you them over time."

[smartass_captain]

The words seem to catch against Jim's mouth, his jaw, his neck. They catch and stick and give them the foundations of a plan. One they're going to have to be very careful in executing lest they both end up thrown out altogether. But in the moment? That risk just makes Jim groan all the sweeter. Shudder for the voice teasing at his ear.

"You g-goddamn tease~" Jim can't manage to sound put out the way they're working each other up. "You want that just as bad, huh..." Wants to pretend they're right there on the bridge and going at each other where the whole damn fleet could see them. God it's a tantalizing thought. And the last punches Jim right in the stomach. Leaves him squirming underneath Spock. The implication that this isn't just a one-time thing. That Spock wants to have this...him. For good.

That this could work. Be real.

"Spock--"

[sensors]

"Yes," Spock says, but it is unclear to which part, whether he means yes he is a goddamn tease, yes he wants that just as bad, or both. He gives them both a squeeze, groaning against Jim's throat, and catches the lobe of his ear with his teeth before continuing. "Shall I elucidate? Inform you that I desire to settle on your lap, to feel you inside me, to let you fuck me," with a slight emphasis on the fuck, purposeful and knowing, "on the bridge in the chair you belong in?"

A lot to say, perhaps, but all the same it does not seem as though he is playing it up: unbridled desire, certainly, but he means every word of it.

Jim squirming beneath him gets Spock shifting, kissing along his neck, under his ear, along his jaw, back to his mouth, granting him a kiss and then breathing out his next words against his lips.

"Jim," with a low thrum to his voice, thick and heated, "tell me what you want tonight. We will have opportunity to explore the rest on other occasions."

Because he does want to have Jim for good. For always, for real, for him.

[smartass_captain]

It's almost too much. Knowing that Spock's been saving up fantasies as long as Jim has. Knowing that despite all of the failed attempts at connecting with someone else they've both kept coming back to each other. To hear that Spock wants more than tonight.

No one's ever wanted to Stay before.

Jim loves him. Jim's terrified. But in the moment all he knows is that he's burning up for how bad he wants this.

"I want the whole damn campus to know I'm yours after tonight." Jim groans. "Wanna have so many marks I can't take a dermagen to all of them." His hands cling tighter. Belying his nerves as well as his Want. "Fuck me stupid so I can..." Jim almost chokes on the words but manages to get out his desire, "s-so I can curl up and sleep with you after..."
