You stood a few dozen feet away from the rest of the Landing Party, your dominant hand idly resting on your phaser as you looked around the undiscovered planet warily. You and your fellow security members were keeping watch out for any...unfriendlies as the team of scientists and Captain Kirk explored their immediate surroundings and as always, you were tense and alert.
While you loved your job and loved to explore strange new worlds, it was stressful to be in charge of multiple lives while on a planet where nobody knew exactly what was out there. But you were one of the best at what you did: your instincts for danger were unmatched as was your dedication to making sure your Landing Party made it back safely (you had the scars to show for that) and you found yourself on more and more security details the longer you served under Captain James T. Kirk.
Not that you were complaining. As a security officer, you didnât see the Captain much on the Bridge as you had no reason to go there, and it was refreshing to see the man outside the cafeteria or training rooms. Especially with the childlike wonder he sometimes possessed when the Landing Party found something particularly interesting. The fact that you found the man incredibly attractive, kind, intelligent and an excellent conversationalist didnât have any bearing on your happiness at being continuously chosen to help guard these missions.
A few soft exclamations of wonder from the Landing Party drew your eyes briefly to the scientists and you couldnât help the smile that crossed your lips, even as your eyes returned to scanning the horizon.
Youâd all landed in a large clearing of different types of vegetation and rock formations, but your eyes kept being drawn to a particular dark part of the somewhat distant forest. Your instincts werenât screaming at you yet, but that section of this planet was making you uneasy.
You and your team of Red Shirts were in a loose circle around the science team, Security Officer Johanson the one that was closest to the dark trees. While there was no official lead on these missions when it came to security â Captain Kirk was the one in charge or the next highest officer if he was absent â the other Officers defaulted to you whenever your instincts came into play. Itâd saved your hides more than once.
You thumbed the private communication line that security shared.
âJohanson â you getting anything from the forest to your right?â you asked quietly, keeping your voice level and even. No use in making anyone panic. You were uneasy, but that wasnât necessarily unheard of on these missions.
You saw the man turn and look, before you heard over the comms, âNegative. Thereâs nothing I can see.â
You replied absently in the affirmative that you received his message, your eyes not leaving the forest.
You stole a glance at the Landing Party and saw that the Captain was already watching you. The man had good instincts too.
As soon as you locked eyes, he started your way and you mentally applauded him. Smart move. If the Captain checks in with Security, no big deal. But if Security checks in with the Captain, that usually means a problem. Captain Kirk coming to you meant that none of the scientists would think that anything was wrong. And there was no reason to panic anyone.
Not yet at least.
âOfficer Y/L/N,â Captain Kirk greeted and you greeted him in return. âEverything still going according to plan?â
Your eyes left the ridiculously good looking Captain to turn back to the forest.
âNot sure, Captain,â you said lowly, ensuring that no one besides Kirk would be able to hear you. âNothing concrete but thereâs something in that forest that isâŠnot right. Nothing threatening or visible â yet. But Iâll admit that Iâm uneasy. And itâs about that particular area.â
The Captain hummed lowly, brown eyes also staring into the part of the forest youâd indicated.
âIn the numerous missions weâve been together on, Officer Y/L/N, Iâve learned to trust your instincts. What would be your suggestion?â
You valiantly squashed both the butterflies in your stomach and the heat to your face at the Captainâs words. Having the trust of a man like Captain Kirk wasâŠexhilarating. But also not the focus right now.
âYou know me, Captain,â you said after a few moments. âI tend to err on the side of caution. We donât know what is on this planet; how big, how fast, how dangerous. Our transporter isnât instantaneous and we beamed down in two different groups because of the size. Iâm tempted to suggest to send at least one group back. That uneasy feeling isnât going away. I donât think weâre the only ones in the immediate area, Captain. But I do think we may be the only friendly ones.â
Captain Kirk was silent for a few moments before you both locked eyes again. He gave you a nod and a small smile, flipping open his communicator and requesting Scotty to stand by.
âA smart move, Officer Y/L/N,â he murmured before turning and heading to the scientists, presumably to tell the ones whoâd be beamed up to prepare.
You tried, with less success this time, to again smother the butterflies that erupted in your stomach at the praise. Honestly, what this man did to you. You never reacted this way to your previous Captains on the other ships and various Starbases youâd served on.
Your eyes again found the section of forest and you thumbed on your communicator to tell the rest of the Security team to tighten the circle. One group was going back for precautionary purposes; they needed to bring it in as well.
You heard multiple affirmatives and saw the team closing in more on the scientists that would be left as the first group gathered in formation to prepare to be beamed back aboard the Enterprise.
The uneasy feeling grew as the transporter beams appeared and spun around half of the Landing Party. Your eyes never left the section of forest, even as the light from the transporter faded and the rest of the scientists continued their documentation.
You trusted the rest of your team to keep an eye out on the rest of the clearing and so felt no hesitation in giving the sketchy forest all of your attention. Even straining your eyes, you couldnât see anything nor could you hear anything â even the scientists were quiet â but the icy feeling that suddenly skittered down your spine had you flipping open your communicator before you could even thing about it.
âEnterprise â beam up the rest of the Landing Party, now!â you barked and then the trees were violently swaying and an earsplitting, animalistic scream from beyond the clearing sounded out.
There were shouts as the security team rushed to surround the scientists and the Captain, yourself included, phasers out and set to stun.
The transporter beams began to shine around you just as a largeâŠthing broke through the trees and hit the clearing at a dead run. You couldnât even tell what exactly it was; some kind of beast with six legs, a large thrashing tail tipped with what looked like spikes and two heads, all on a mottled brown and black body that stood at least three stories high.
One head let out another ear-piercing scream while the other snapped large jaws filled with sharp fangs open and shut.
It was fast. Too fast. There was no way that the transporter would get you all up completely before it was upon you. Either it would end up on the Enterprise with you, or multiple people in the Landing Party would be gored or grievously wounded before disappearing from the planet.
Your body tensed as you came to a decision and you shot a quick look over to the nearest Security Officer. He looked grim but nodded and then grabbed the self-sacrificing Captainâs arm.
The Captain cottoned on immediately and shot you a glare. âOfficer Y/L/N, donât you dareââ
You grimaced but then unhooked your phaser and took off at a run, firing at the beast as you went to try and draw its attention away.
And it worked.
Boy did it work.
The beast skidded into a turn that you were surprised it could make given its size and took off after you. You continued firing at it as you ran, realizing quickly that any hits it took, or any dodges it had to do, slowed it down enough that it kept you alive.
Thankfully, while the sketchy forest where this sucker had apparently been lurking had taken up the majority of your attention, you had made a thorough visual sweep of the area when youâd first beamed down and there was a tall formation of rocks not too far away with what had looked like a small cave. Hopefully, it was a cave large enough to hide you until the Enterprise could beam you up.
If not â well, at least you wouldnât have to worry about the disciplinary action that was sure to await you if you even got back to the ship.
Another scream sounded out behind you â much closer than before - and you shot your phaser behind you again, managing to hit the beast it one of its mouths. It stumbled, shrieking and thrashing and you put on a burst of speed youâd never reached before and shot up into the nearby rocks, scrambling to keep your footing and find the cave youâd seen earlier.
The beast had recovered enough that it was now climbing the rocks after you, howling and screaming, large taloned feet carving deep gouges into the sturdy rocks. Another phaser blast had it screaming and tumbling down to the grass below and you almost cried with relief when you saw the cave â and it was a cave.
You scrambled into it, phaser still in hand and went as far back as it allowed. Hopefully, it was far enough that the long, six legs of the beast after you couldnât reach.
You could hear said beast still howling and growling, though you couldnât tell if it was getting closer. And you were certainly not approaching the front of the cave to check.
Your chest was heaving and your heart was racing, but you gulped in lungfulâs of air and flipped open your communicator, hoping to get into contact with the Enterprise. If they could just get your signal in the caveâ
You werenât even able to say anything into the communicator before you heard the Captainâs voice come over the speaker and then saw the transporter beams start to encircle your body.
âY/N â weâre beaming you up â hang on!â
You answered with a worn out yet relieved, âAye, Captain,â not even sparing a thought to the Captain calling you by your first name. No, your attention was on another thought as you faded along with the transporter beams.
You were so going to be fired when you got aboard.
/////\\\\\
Thankfully, Doctor McCoy was in the transporter room as well and had whisked you away to Med Bay to check you out after your âstupid and reckless heroicsâ. It was good to know you had a fan.
Captain Kirkâs heavy gaze had followed you both out and you werenât sure what was worse, getting fired now, or being able to stew about it while in Med Bay and then getting fired later.
Probably the latter, but at the same time, you were glad for a short respite to get yourself back in order. Youâd face your disciplinary the same way you faced everything else; straight backed and stoic. You wouldnât show your devastation at being reprimanded and canned by your superior nor would you show your grief at having disappointed Jim. That was going to hurt worst of all.
But if you were going to go into this without showing the mess of your emotions, youâd need a few minutes to collect yourself and you mentally thanked Doctor McCoy for giving you that, even unintentionally.
âYou scared him, you know,â the Doctor spoke up suddenly as you both walked side by side to Medical. You looked over at him and then gave a sigh, facing back to the front.
âIâm aware that the decision I made was not one he approved of,â you murmured. But youâd do it again in a heartbeat.
âNot what I said, nor what I meant,â McCoy said gruffly. You looked at him in confusion and he fixed bright blue eyes on you.
âYou scared him,â he repeated. You stared at the Doctor for a moment before shaking your head.
âIâm sorry, Doc, I donât know what you mean.â
The man gave a long suffering sigh, muttering something about being a doctor not a counselor and you just gave him a bemused look. You liked Doctor McCoy â had been fixed up more than once by him â but he was definitely a curmudgeon.
The Med Bay doors opened and you both walked in, the Doctor directing you to take a seat on one of the bio beds while he looked you over.
Other than a ridiculous amount of adrenaline (that was leaving fast and leaving utter exhaustion in its wake) and some superficial scratches on your palms and arms from your rock climbing adventure, you were fine.
But McCoy tended to the scratches like they were life threatening and you found yourself struggling to stay alert and awake. Youâd need your wits about you for your upcoming verbal thrashing from the Captain, but all you really wanted to do was sleep.
âIâve never heard or seen Jim that scared,â the Doctor spoke up again suddenly and you hummed, not really sure how to say âI donât understand what youâre talking aboutâ again without making him upset. Blue eyes once again focused intently on you. âYou sacrificed yourself for the Landing Crew â him included. You had an Officer hold him back so he couldnât go after you.â
âActually, I had an Officer hold him back so he wouldnât sacrifice himself,â you corrected absently and Bones gave a loud huff.
âAnd how is that better? Bit hypocritical, isnât it?â he demanded and you narrowed your eyes. You could â and would â take any disciplinary action since you technically violated an order from your Captain (even though it wasnât stated explicitly as an order but everyone there knew it had been) but you wouldnât just sit here and take what sounded like a slight to your character. You were doing your job.
âCaptain Kirk is the Captain,â you bit out. âItâs literally in my job description to not only protect him, but anyone whoâs on board this ship. I made a calculated and correct, I might add, call that the creature was gaining on us too fast for us to escape unscathed by transporter. The Captain is more important than a Security Officer,â continued, holding up a hand when Bones opened his mouth to presumably argue. âIâm not saying that in a self-deprecating way â itâs fact. While I will do anything in my power to not die, if itâs a question between me and someone in a Landing Party or the Captain of the Starship himself, itâs going to be me â every time. Itâs what I signed up for.â
There was silence in the Med Bay as you and Doctor McCoy stared each other down. For all his intimidating glares and words, you werenât going to back down â not about this.
Yes, technically, you disobeyed a direct order â but youâd saved the lives of everyone in that Landing Party. As far as you were concerned, you were just doing your job.
Though why no one else seemed to see it like that was both a mystery and incredibly frustrating.
âJim, I hope you got all of that,â Doctor McCoy said suddenly, voice raised to the ceiling and then the Captainâs voice sounded out, âAffirmative. Iâll be there in a moment. Kirk out.â
You shot the Doctor a betrayed look.
âWow. Just going to ream me in front of an audience, then?â
Bones snorted. âYouâre too professional,â he said bluntly and you rose a brow. âToo professional when dealing with the Captain when youâre not actively on a mission,â he corrected. âThere was no way you would have said what you really thought or felt when he asked you â you would have just taken whatever he said and said âokayâ. This way, at least he knows what was going through your mind when you sacrificed yourself and scared him half to death.â
You rolled your eyes, feeling the exhaustion creep in even further. âYou keep using that word. Iâm not sure it counts as âsacrificing myselfâ if Iâm still here. And why do you keep saying I scared him? What does that even mean?â
âIt means that I care,â came the Captainâs voice and you jerked your head around to see him leaning against the doorframe of the Med Bay. You hadnât even heard the doors open.
Kirk stalked to the bio bed you sat on while Doctor McCoy gathered his supplies and headed for his office, leaving the two of you alone.
Wonderful. Is this the part where you got fired?
âIâd ask what you were thinking, but thanks to Bones, I have a pretty good idea. You know, itâs the Captainâs job to go down with his ship, to sacrifice himself for his crew.â
You figured you were going to be fired anyway (or at the very least with a black mark in your otherwise pristine record) so you might as well go for broke.
So, you rolled your eyes. Hard. âFirst of all, Captain, will all due respect â no. Thatâs not how that goes. If that were the case, and no one but you was supposed to be âsacrificingâ themselves, there wouldnât even be Security Officers. Second of all, the Captain is not technically supposed to beam down with Landing Parties, so thatâs also a moot point. You werenât even supposed to be there. And thirdly, sir, respectfully again, youâre an idiot. A Captain is not a good trade off for a Security Officer. One clearly outranks and outweighs the other. You know it and I know it. Starfleet knows it. Thatâs why itâs in my job description.â
Kirkâs eyes flashed and then he was standing right in front of you, so close you could feel the heat coming off of him and could feel your knees touching his thighs.
âSo you just decided that you could disobey a direct order and go and try to get yourself killed?â he ground out.
You scoffed, feeling your face heat (and not just in anger). âI hardly got myself killed, Captain,â you hissed back. âAnd I was doing my job.â
âYou had someone hold me back.â
âYou have a bad habit of trying to get yourself killed â it seemed prudent.â
âThatâs not your call to make.â
âActually, it is. Perhaps I should send you my job description so you can see for yourself?â
âSarcasm isnât going to get you out of this.â
âBut proving I was doing my job might.â
You were both glaring at each other, chests heaving and eyes flashing.
And then, he was stepping between your legs, grabbing the back of your neck and crashing his lips onto yours in a bruising kiss.
Time stopped.
Your brain tried valiantly to reboot but all you could feel and see and smell was Kirk. The Captain was kissing you. Jim was kissing you.
You closed your eyes and kissed him back.
Your hands skirted up his arms to wrap around his neck as you pulled him closer, giving as good as you got, fighting in your kiss just as quick and bold as your argument.
ThenâŠit shifted, gentled. It was no longer a demanding, hard kiss, but a softer, pleading one. Jimâs hand on your neck softened, fingers now caressed instead of gripped. Your own hands loosened and slid into his hair and along his shoulders, causing him to groan as your fingers scratched his scalp.
The kiss ended gently, but Jim didnât move away, he stayed in your space, forehead pressed against yours, your breath mingling.
âYou scared me,â he murmured after a moment, echoing what Bones had told you three times. âI thought that Iâd lost you. Lost you before IâŠbefore I got to get to know you better. Got toâŠcourt you.â
You blinked up at him in surprise. Sure, youâd spoken to the Captain a lot of times and had been on numerous missions with him but you had no idea youâd apparently affected him as much as heâd affected you.
The swarm of butterflies in your stomach you were sure youâd squashed came back with a vengeance and you felt your heart jump.
âReally?â you asked quietly, not quite believing, but desperately wanting to. Â
The Captain â Jim â gave a soft huff of laugher. âReally, Sweetheart. And assuming youâre open to it, Iâd like to start getting to know you better starting now.â
âNot in my Med Bay!â McCoy yelled out from his office and you groaned in embarrassment, your head falling to rest against Jimâs chest as he threw his own back and laughed.
âDuly noted, Bones,â he called back, grinning. âWeâll take it elsewhere. Iâm assuming sheâs cleared to leave?â
âYes. Cleared. Get out of here!â Bones grumbled. Jim gave you a soft smile, though his eyes were still twinkling and helped you down from the bio bed.
âHow about a short date in the cafeteria before I walk you to your quarters so you can sleep? Youâve had an exhausting day,â Jim suggested as you both headed for the Med Bay doors and you gave him a bright smile.
âThat sounds perfect.â
The answering grin on his face made your chest jump funny and you found yourself walking side by side with a man who you had admired for afar and now were being courted by. Life really had a funny way of working out.
And you didnât even have to get fired.
