Work Text:
You want to fuck your head engineer, but you really shouldn’t.
You come to this conclusion one day as you’re just watching Mark go about his duties aboard the ship, talking with other crew while you wait for a report you need from him.
He’s all gentle smiles with a (mostly) sharp mind behind it, and it helps that he looks like an absolute snack, even in a beige flight suit, white turtleneck, and red beret.
“Captain?” You startle out of your thoughts, only now noticing that Mark is standing right in front of you, tablet in hand and a small frown on his face.
“Apologies, go ahead Mark.” He gives you a curious glance, but goes on to give you a brief overview of his report, before sending the full thing to your own tablet.
“Great, I’ll take a look at that in my own quarters, you’re dismissed.” Wanting to get some distance between you and him, as to perhaps avoid embarrassing yourself in any way, you quickly turn around, missing the furrow between Mark’s brow, created by your unusual abrupt dismissal of him.
In not too long you’re in your cabin, seated on the edge of your bed. You tug your gloves off and throw them and your tablet to the side, sighing as you put your head in your hands.
You have to squash whatever you’re feeling for Mark down, you can’t feel that way about him.
It’s unprofessional on so many levels, and though you would like to think that those stolen glances Mark sometimes took of you, (and that you’re certain he wouldn’t want you to notice), means something, you can’t fuck him.
Though you really want to, and you think he might feel the same.
“Fuck.”
Your door slides open just then, the computer announcing the arrival of just the man you had been thinking about.
In your hurry to get on your own, you had forgotten that the only other person with access to the captain’s quarters is Mark.
You hear the door sliding closed again, and some shuffling of feet.
“Captain, are you okay? You left rather quickly back there.”
“I’m fine, just…..” You don’t know what to say, letting the silence linger.
“Captain?” Mark asks, and you take a deep breath, looking up from your hands.
One of Mark’s arms is stretched out towards you, like he was about to touch you, but pulled back at the last second.
He looks so worried, and fucking hell, even now you can’t help but notice how good he looks. How handsome he is. How you care for him. How much you want to touch him, and have him touch you.
A few seconds go by, nothing being heard in the room except the gentle and ever present hum of the ship.
Fuck it.
Standing up abruptly, you stride forward with determination, causing Mark to back up.
His back hits one of the metal walls, and then you’re crowding into his personal space.
“Captain?!” The title is said in shock and with a tone of something you can’t quite place, and you don’t allow yourself to think about it before you are kissing him.
Mark lets out a squeak of surprise, drawing in a sharp breath as your lips press against his.
For a few painful seconds there is nothing, and then his hands are in your hair, knocking your captain’s hat off in the process.
Relived as all hell, your hands come to rest on his hips as he kisses you back, eagerly pulling you against him. His beret falls to the floor, forgotten in seconds.
You lick along his bottom lip, and without hesitation his lips open, allowing you entry. His tongue comes out to meet your own, making you groan somewhere far back in your throat.
One of your hands shifts down from his hip to his thigh, then under his knee, gripping it and pulling it up so you can grind your hardening cock against his.
He moans against your mouth, rolling his hips up as well as he can, just balancing on one foot.
He keens under your touch, his hands in your hair tugging you back every time you try to end the kiss. He’s letting out small whimpers and moans, making your pants feel tighter by the second, but like this neither of you are getting enough friction.
Getting an idea, your second hand slides lower too, and with some maneuvering and the element of surprise, you have picked Mark up fully, all of his weight in your arms.
This causes him to break the kiss, winding his legs around your hips on instinct. He looks down between your bodies, moaning as your roll your hips against his once more, friction delicious, and just what you want.
“You okay with this?” You have to ask, even as you can feel his hard dick pressed against you with every roll of your hips.
“Yeah.” He’s a little breathless, and as you make eye contact with him he licks his lips. His hands have moved from your hair, one resting on your shoulder while the other plays with the hair at the nape of your neck.
You lean forward to kiss him again, capturing his lips with yours. You press him hard against the wall, causing Mark to moan into your mouth as you grind against him.
Pressed against the wall like this it is easy to get one of your hands free so you can start tugging down the zipper on his uniform.
You fumble with the zipper before Mark takes over, zipping it down to his belt without an ounce of hesitation. He shrugs out of the arms, and you find your fingers meeting bare skin on his upper arm. You move back slightly to look at him.
To your delight you discover that it’s not a proper or full turtleneck, but instead more of a tank top with a high neck.
“I don’t think that a tank top is part of the engineer’s uniform.”
“Well no, it’s not, but it can get rather hot when working on things, and sometimes sleeves get in the way so….”
“Mmhm.” You look him over, taking in how his broad chest is rising and falling with each breath, how the muscles in his arms flex as they rest on your shoulders.
“Why did you leave so abruptly earlier?” The timing of the question isn’t the best, but you don’t blame him for it.
So you decide to be honest with him.
“I was thinking about this.” Mark tilts his head, a light frown grazing his lips.
Time to be blunter.
“I was thinking about how much I wanted to fuck you, and how I really shouldn’t.”
“Oh.” A few beats where neither of you say anything. “Do you still want to?” You laugh, moving Mark to get a better grip on his thighs, your hard cock pressing against him again, making his breath hitch.
“What do you think?”
“I think I want you to fuck me.” He says it so matter of factly that it takes a few seconds for the words to catch up in your brain, and then you’re grinning. Mark huffs at you.
“What?” Your grin doesn’t fall as you ask.
“You look like the cat that just ate the canary.”
“I haven’t eaten you yet, but perhaps another time.”
“Another time?” Mark parrots, and you kiss his stubbled cheek.
“Yeah, if you’ll let me. Right now though, I just want to fuck you against this wall. You okay with that?” The answer you get is Mark pulling you in for another kiss and grinding down on you. You moan into his mouth.
Moving your hand so you’re just holding up Mark with one arm while pressing him against the wall, you start pushing at his belt. He seems to get the memo, and seconds later it falls to the floor.
This makes it so you can pull the zipper of his jumpsuit down that final little bit, and get your hand inside it, and on Mark’s cock. You press your hand against it, and Mark moans into your mouth. You stroke him through his boxers, and Mark breaks the kiss to lean his head back with a groan. You take the opportunity to kiss on the underside of his jaw, tracing the light stubble that covers it.
“I think the uniform needs an adjustment.” You murmur against Mark’s skin. You can hear him swallow as your lips dance along his neck, just on the edge of his turtleneck, your hand still on his cock.
“Oh?”
“Mhm, no more turtlenecks.” Mark laughs, and you find yourself smiling as you lean back so you can look at him.
“I’m serious, deep v-necks only from now on.” You try to scowl, to be the serious captain, but you can’t, instead starting to laugh alongside Mark.
“And I’m sure people would have no questions at all about that.”
“Oh, they would, but I’m the captain, so sometimes not everyone needs to know my reasoning. Plus, I don’t think we would want to tell them the reason is me wanting easy access to your neck and to show off what a mess I can make of your skin.” Mark flushes at your words, the hand on your neck squeezing.
“There’s one way to get easy access.” Your hand inside his flight suit stops as you wait for his idea, making him shift his hips. “Set me down, and I can get everything off.” A beat as he looks up and down at you. “And so can you.” You hum, giving him a once over as you pretend to think about it.
“I guess you got a point.” Gingerly, Mark unwinds his legs from around your waist, and with just a little help, he’s standing on two slightly unsteady feet. His flight suit immediately pools around him, and in seconds his turtleneck tank-top is wrenched over his head.
You can’t help but stare. You knew Mark looked good, but seeing it fully and not covered by his uniform is making your mouth water. You’re already thinking about where you can put your mouth next, and how you would like to map every inch of skin.
Your attention is turned back to the moment as Mark clears his throat, turning your attention upwards. He should look a little ridiculous with his flight-suit pooled around his feet, clad only in his underwear with messed up hair. But instead he only looks good, perfect even.
“Are you going to fuck me with that hot uniform on?” You blink a few times, and then your captain’s jacket joins your hat on the floor. Mark grins, and in only a few short moments you’re both naked.
Once again you crowd into Mark’s personal space and press him against the wall, but this time you’re met with a moan instead of a squeak of surprise. You put your hands on his hips as you lean in to speak in his ear.
“Jump.” He does as he’s told, and with ease you catch him, and his legs goes around your waist again. You grind against him and Mark almost seems to choke on thin air.
“Fuck, that has no right to be as hot as it is.”
“What, me being strong?” His neck now free from barriers, you take the opportunity to place kisses along it.
“You manhandling me.” Mark speaks towards the ceiling as he tilts his head to give you better access.
“It has its advantages.” You mutter against his skin right before starting to make a hickey. Mark groans, trying to move down against you as you do.
“Oh, fuck me.”
“Oh, believe me, I plan to.”
“Lube?” He pants, and you frown. You don’t want to put him down now that your hands are back on him, but fucking him dry is not an option.
Which leaves you with a bit of a conundrum.
But, you’ll manage.
You shift your hands, going back to having one hand on Mark, while the other is free, making extra sure your grip on him is solid.
“Captain?” He questions, and then you lean away from the wall, taking Mark with you. He gasps, arms and legs clinging to you for dear life.
“Holy shit.” You grin and chuckle as you slowly make your way over to your night stand. Somehow, with minimal bending of your knees you manage to get the drawer open and fish out the lube you keep there.
A few more steps, and you press Mark against the wall once more.
“You know, your bed was right there.” You hum, noising at the junction between his neck and shoulder, placing a kiss there.
“I know, but we established that we both find this hot. So now I’m going to fuck you against this wall. Understood?” It’s not really a question, because both of you know Mark’s answer, but you still feel him nod.
You hold up the bottle of lube between the two of you, waving it back and forth so Mark’s eyes fixate on it.
“Take it.” He frowns, but does as he’s told. You move your hand so your palm is upwards, fingers facing him. “Lube.” His eyes widen.
“You’re making me pour out lube for you?”
“It’s for the both of us, and I’m not making you do anything, but I’m not going to fuck you dry, sooooo…” You draw out the word, curling your fingers at him. You see him blush, and oh does that look lovely up close. Glad it’s an easy one, Mark pushes the cap open with his thumb and pours lube onto your fingers and palm. He keeps the small bottle in one hand behind your neck as you grin at him and he swallows.
Your now wet hand travels between your bodies, briefly brushing against Mark’s thigh and cock, leaving a slick trail on his skin. Your hand travels down further still, fingers resting against Mark’s hole.
“Are you just going to just tease me?” Mark sounds impatient, but the effect is made almost charming as you can hear how breathless he is already, and you have barely touched him.
“Another time.” You push one finger in then, hearing Mark’s breath hitch, and seeing his eyes widen. You catch his lips with yours, wanting to feel him moan against you.
And moan he does.
For you discover to your delight that he is not one for being quiet as pleasure curses through his body with the demonstration of just what you can do with just your fingers.
You start with one, sliding it in and out of him at a slow pace as you kiss him. Feeling how he contracts around just the single digit, and knowing you will have to work him open for more.
And you are more than up to the task.
You add another when he tries to move down on your finger. You smile against his lips, and you feel him huff. You let your lips wander down the side of his neck as you adjust your grip on him, making his legs tighten around you even more.
“How in the fuck are you doing this?” He keens at the last words as you nip on his neck, thoughts already wandering to covering him in hickeys in all the places you can reach.
“I workout, and all that stuff. Worth it, don’t you think?”
“Fucking hell, yes!” He tugs at your hair with his free hand as you gently move your fingers slightly apart, accessing if he is ready for a third finger.
You decide he is, but you need more lube. So with the next move of your hand, you pull out of him completely, making him whine as you bring your hand up between you again. You shush him, and when he spots your hand, he is quick to give you more lube.
You waste no time now, thrusting three fingers inside of him seconds later. He groans, and you know it’s a bit of a stretch, but he pulls you in for a kiss, drowning his groans against your lips. Your tongue comes out to meet his, and it’s getting harder and harder to concentrate on anything else than how good he is feeling around and against you.
But, unfortunately, at least for you, your wrist is beginning to cramp.
So, you pull your fingers out of him. Using the lube that is still on your hand, you give yourself a few strokes.
Mark stops kissing you, but only to look down between your bodies. He licks his lips.
“Like what you see?” You tease. Mark looks up at you with wide eyes, nodding as he feels you line yourself up and press against his rim.
He moans as you push inside him, and you do too, loving how tight and warm he is around your cock. You don’t have to move a lot, gravity doing most of the work as Mark sinks down onto you.
As you bottom out inside of him, you hide your face in his neck. Well, it’s more to let Mark adjust to you, and moving your attention to kiss at his neck to keep yourself to fuck up into him at once.
He feels so good, and he flexes and moves against you as you start on a hickey. The lube bottle falls from his hand, sliding down your back as it falls to the floor, making you chuckle low to yourself at the feeling. Both of Mark’s hands are in your hair now.
“Fucking hell.” He’s not normally someone who swears a lot, so hearing your head engineer loosing control over his words like this, before you have even fucked him makes your cock twitch and a heat settle somewhere in your chest.
“Move.” The word is shout-whispered in your ear as Mark tugs at your hair.
Groaning, you do as he (and you) wish. Slow at first.
Just barely moving him up and down on your cock as Mark lets little noises fall from his lips. When he tries to hide them by putting a hand over his lips, you stop fucking him so you can tug it away and pin his arm for the briefest of moments. You lean back from marking his neck to look at him.
“Let me hear you.” He nods, breath labored and his hair plastered to his forehead.
Normally, you don’t keep your cabin any warmer than the rest of the ship, but now it feels at least several degrees hotter than any other room.
Even the reactor room can’t compare with how hot you feel as you fuck up into Mark, making him moan and whimper with every flex of your arms.
It gets even warmer when he starts to try to fuck himself down into your cock.
You take the hint, and speed up, your cock slipping in and out of his with wet sounds, hitting him deep every time as your quarters is filled with the sound of skin hitting skin.
You shift Mark in your hold, and that seems to send your cock into him at a new angle, as on the next thrust up he moans the loudest you have heard so far and shakes around you.
You grin against his shoulder, licking at a hickey you just made.
“That feel good?”
“Ahaaa, yes!” Mark tugs at your hair, and you find yourself kissing him as you fuck into him. It’s messy and uncoordinated, but fucking hell it’s so god damn hot you can’t find yourself to care. Not even as Mark bites your bottom lip a little too hard, making your lips bleed with the next rough trust from you.
You pull back, licking your lips in surprise, but you keep up the pace, not one to stop now. Mark grins sheepishly at you, licking his own lips as he tries to speak in-between moans.
“Sorry.”
“Don’t worry, you can make it up to me later.” His grin isn’t sheepish any longer, instead something twinkles in his eyes as he tilts his head.
“Is that a promise?” You lean forwards to whisper into his ear
“It’s whatever you want it to be.” Mark giggles, then moans as you hit his prostate again. You grin, still tasting the slight tang of blood on your lips, but you truly don’t care.
You dive in to kiss Mark again, already forgiven him, but making plans in the back of your mind of how he can make it up to you in the future.
It should be a little embarrassing how little time it takes for you to get close, but Mark feels so good that you can’t help this.
Not wanting to break the kiss to tell him, you instead shift so you’re once more just holding Mark up with one arm and pressed against the wall. Your hand goes to his cock, tugging as you want him to come with you.
Mark seems to understand, or perhaps he is just chasing his own pleasure. He fucks into your hand as your cock slides in and out of him, and in surprisingly few tugs, he is coming all over your hand and his own stomach. You groan against his mouth as he shakes apart around your cock, the feeling of that sending you over your own edge.
You cum hard, having to break the kiss to gasp, hiding your face against his neck as you fill him up with your cum. Mark grunts, one hand pressing your head against his neck as the other grips at your shoulder.
A few moments are spent like this. Mark being filled up by you, pressed against the wall for support as you both catch your breath.
It takes Mark muttering your name, your actual name instead of your title, to make you lean back and look at him.
“I think I should get down.” You nod, grunting as you pull him off you and help him to stand. You can’t help the little laugh as he almost topple over him before you support him. He glares at you, but the effect is somewhat ruined with how fucked out he looks. Neck and shoulder covered in hickeys you made, sweaty with your cum dripping down his thighs.
“Your fault.”
“Guilty as charged.” You lead him towards the bed and he goes willingly. He sits down on the edge and you follow so you’re kneeling between his legs. Your hands dance over his thighs as you press a kiss against the side of his lips.
“We should get cleaned up soon.” You hum, shifting to kiss all over his face.
“In a little bit, now I just want to keep you close.” Mark huffs, hands coming to rest at your shoulders.
“You could get up on the bed with me, it would get you a lot closer.”
“I suppose you got a point.” You get off your knees, getting into your bed, Mark is quick to follow. He tries to settle on his side next to you, but you pull him on top of you instead.
“I don’t think I can get much closer now.”
“No you can’t, plus, this way my cum is not leaking out on the sheets.” Mark groans into your chest as one hand comes to grope at his ass.
“You!” You grin at the ceiling, and Mark shifts so he leans on one hand, most of his weight still on you.
“Me.” You answer. You go to stroke away a lock of hair, but wince as something pulls in your wrist. Mark eyes it, frowning.
“Next time I think we should be more careful of your wrist, no matter how hot that was.”
“Oh, so you’re going to do all the work next time?” He reaches his tongue out at you, but you just grin at him as you lean up to get another kiss from him. “Worth it.” You mumble against his lips, Mark just huffs at your statement.
(When Gunther asks about your iced wrist the next morning, you just say you tripped as you can see Mark ducking his head in an attempt to hide a blush.)
