"Er, Ｃaptain? Your Ｈead Ｅngineer has found an issue with the proposed hot-weather uniforms... seems the zippers have a tendency to stick."

y'all saw this post going around a while back right?

well I saw it again tonight (about two hours ago) and my brain would not let me rest until I'd drawn this (in the last two hours)

[electronic-elevator]

burt trying to save mark from an accident be like burt: the reckless man who drinks too greedily from the fountain shall find his cup runneth over sooner than he thinks. mark, squirming and leaking without noticing: what the fuck are you talking about. burt: youre wetting yourself mark

WHEEZE. like ok Mark honey I know sometimes Burt can be a little opaque but you really probably could've figured that one out

also after Burt just comes out with it bluntly Mark fussing like you could've been a little more subtle, jeez, someone's going to hear..! and Burt is just like. Sigh.

[electronic-elevator]

I imagine engineer to be the kind of guy who gets super focused on what he’s doing and tunes out his own bodily needs until he’s done...... please imagine him idly fidgeting and squirming while he works, not even realising he’s growing more and more desperate until the tiny little leaks he’s been having suddenly turns into a spurt, and he drops what he’s doing to grab himself, whining and panicking because oh god, he has to go so bad, oh no, and maybe he just barely makes it to the bathroom, jumpsuit damp and streaked with leaks. or maybe he doesn’t make it, pissing himself, all red faced and embarrassed at himself. and maybe the captain accidentally sees him wet, bumping into him in the hallway while he’s trying to get to the bathroom, inadvertadly making him lose focus and wet, and then they’re making sure to keep an eye on him, seeing him start to shift and squirm and leak, and gently reminding him to take a bathroom break, or consoling him when he has an accident..... soft cap helping their leaky engineer 🥺🥺🥺🥺

oh absoLUTEly

even if he notices at first, he'd push the urge aside, not wanting to stop before he's finished his task -- but after doubling-down on their focus, they won't realize that it's going to be too late before that task is finished

I also LOVE the concept of, even if the person who's wet successfully sneaks away, someone else finding the puddle while they're gone -- so the Captain coming to see him for something but finding an empty workstation with a suspicious puddle. And just then, Engineer coming back and having to stammer out some excuse about having spilled something -- which doesn't add up as there isn't anything liquid on the workstation, and besides, why would that make them blush?

and once the Captain has caught on, the little "do you need to--?" reminders being often met with an initial "no! of course not!" before the lapse in concentration allows those urgent messages from his bladder to finally register and he's got to sheepishly excuse himself after all, mumbling a thank-you....

[electronic-elevator]

STOP THAT WAS SO FUCKING GOOD!!!!!!!! Mark ignoring caps so genuine reminders, feeling guilty but so so so good as he feels himself squirm, every movement going right to his cock, the captain purposefully not reminding him, watching as his subconscious squirming gets more and more frantic, savoring it, watching him all hungry and turned on....... the image of engie furiously jerking off in a bathroom stall, stumbling back against the door, one hand over his mouth to quiet his moans, the other half holding himself half stroking......... the cap STOPPING HIM GOING.... him feeling so humiliated and exposed but so so hot and positively shaking with arousal, the cap praising him and watching as he tries so hard to be good for them, keep holding like a good engineer, but he just!!!! can't!!!!!! OOUWOWOAHWOAH 💖🥰🥰😳😍😳💖😍🥰😍💖🥰😍💖💖🥰🥰🥰😳😍😳😍💖😳💖😍💖🥰🥰😳😍😳😍

thank you omfg

just that "am I dreaming?" moment of the Cap stepping up and trying something with him after he'd fantasized about it for so long,,, of being encouraged to hold it, and it feeling so much better when it's all for their Captain... Engie deserves it uwu

[electronic-elevator]

but also!!! the other way around!! cap watching engie squirm and tap his foot and jiggle his thigh out of the corner of their eye, knowing they should remind him to go to the bathroom, but they feel so warm and tingly watching him all desperate...... waiting until their guilt outweighs their arousal and they gently remind him, then watching as he rushes away, trying to ignore the throbbing in their arousal....... them watching as engie wets, knowing they should look away and give him privacy, let him keep his dignity, but being captivated, flushed and stunned.... then helping him get out of his wet jumpsuit, trying so hard not to let their touch linger, knowing their feelings are such a betrayal of engies trust...... them being desperately horny about it until engies dry and clean and they can excuse themselves and immediately hide in the nearest lockable empty room to jerk off and feel so guilty and awful about it...... and engie misinterpreting the caps body language as disgusted, being so upset and teary and apologising, and cap swears to not let this stupid reaction they have get in the way of making sure engies okay.... which means more guilty jerking off later to sate themselves...... I simply think leaky weak bladdered chars who have a partner that not only doesn’t judge or find it gross but is also Super Into It is top tier

YEAH YEAH YEAH. they're already idiots in love and in denial about it and this only adds more fuel to the fire. the Captain can't just say they're distancing themself b/c they're aroused by Engie's very real, very personal issues but they also can't hurt Engie like this, so they've just got to try to act Extremely Normal

which does. not work. there's just no way that works.

consider: Engie following Cap shortly after getting cleaned up to confront them b/c they're hurt and angry that the Captain keeps insisting it's fine but then acting the same damn way, but when they catch up to the Captain finding them obviously aroused. if Cap has a dick this is pretty simple to orchestrate... half-hard in their own jumpsuit, pupils blown, face flushed. Reactions Engie hasn't really noticed before because he gets caught up in his own shame. And suddenly they're mostly just confused.

[electronic-elevator]

oh gunther inadvertently making mark wet himself with his gunfire.... he was trying to help!!!! he apologizes and helps mark cover, since it was his fault, really, and next time he makes sure to give mark a warning before he shoots for a distraction. celci would be a lil awkward but she does her best and never uses his accidents against him in an argument.... and burt sends the cap a several paragrah poem and caps like "oh, mark needs help, okay" lmaooo

YEAH. Mark just. ;~; and Gunther like,,, oh god I've made a terrible mistake. how were guns nOT THE ANSWER, guns are always the answer...

ok also. Gunther is highkey the "wait, it's okay, I'll wet myself too to make you feel better!" type, change my mind. Gunther doing this planet-side and the two of them having to walk back to the shuttle in soaked pants. (This does NOT make the Engineer feel better.)

Like Celci needs to resort to such a low blow to win an argument with/about Mark ;3 (The Engineer has noticed and appreciates it deeply... but if anything that fact drives them crazy b/c they still like to pretend they don't like her and don't want to think about her being considerate/kind. x3c )

Burt my beloved. ... Also consider him trying to nudge Engie towards a bathroom break but Engie's just nnnot getting the message, distracting/delaying him in the process, and wetting as a result. Burt's like, I warned you! but Mark's like YOU DID NOT 😭

I just love the crew omg 😭

[electronic-elevator]

engie being so torn, cause on one hand, they love love love when the captains holds them after he wets, stroking his cheek and telling him it’s okay, he did his best, and when they help him clean up so no one else knows, they feel so special and safe and loved, but also!!!! they can’t just keep having accidents like this!!!!!! in front of them, no less!!!! it’s embarrassing, and he really is running out of jumpsuits, but........... it’s still nice..... maybe, when he knows they won’t be busy, and there’s no scheduled work with other crew mates, and it’s just the two of them, they’re maybe only PRETENDING that he hasn’t noticed how bad he has to go, waiting for cap to say something, anticipating their comfort......... 🥺🥺🥺 CAP AND ENGIE BOTH SECRETLY LIKING IT........ ughugughuhguh engie clutching at his dick through his jumpsuit to try and hold it, but the panic starts to meld with pleasure, and the rocking becomes more about that low burn in his cock than stopping himself from peeing, and when he finally, finally wets, he could probably pass off the breathless moans as from relief, but then he realises his dick is so obviously hard now his jumpsuits all wet and clinging to his skin...... or when the caps helping him clean up, unzipping his soaked jumpsuit, they realise why he’s so much more flustered and red than usual, his cock twitching at their gentle touch...... 🥺 it just!!!! feels good!!!!

between the embarrassment not only of wetting himself but of kind-of-sort-of having done it on purpose AND now the Captain seeing him hard and why he's reacting like this... but he doesn't want to ask them to leave; they still want their help cleaning up... and maybe more, because let's be real, the Engineer has been in love with the Captain for ages, even if they've never done this before. Engie's flustered and it's difficult to think and they mumble out an apology, claiming they don't know why, but the Captain says it's okay, and they seem flustered, too

honestly my main hc for these two is like. they've repressed their feelings for each other since the academy and so are entirely unlikely to switch gears and Go For It the first time this happens. so Cap just helping Engie get sorted, like usual, but god he can't stop thinking about the way it felt; the way he had to bite his lip to keep from asking Cap for more even after they'd gotten him clean. The Captain alternately wondering if they'd gone too far, or if they should've asked if he wanted them to go further... That night, Engie whimpering the Captain's title into his pillow, thrusting into his hand...

[electronic-elevator]

fuihdjkgdkd yes it was me (sorry for spamming asks,,, I simply saw another markcu and omg enjoyer and went a little feral) ohhhh I love when they’re so so so close to relief, the toilet right in front of him, and his body KNOWS it, and they’re jumping in place and whining and alternating between trying to get their jumpsuit open and holding themselves, trying to stop the leaks, they’re so close, please, but they just!!! can’t!!! the cap noticing he’s been gone for his bathroom break much too long and engie having to call them, all sniffing and mortified and mumbling that he didn’t make it, can they come help, please?? and if he DOES just make it, he comes back all shuffling and embarrassed, trying to hide his crotch, but the cap can SEE the dark streaks down his thighs, and they ask if he wants to change, and he’s all flustered and saying no!!! he made it!!! it’s fine!!! he DIDNT have an accident!!! 🥺🥺 or or or early on, he’s insisting he’s fine, he can hold it, it was ONE time he had an accident (it was not) and he doesn’t need to be treated like a kid!!! and it’s only when he’s leaking huge spurts and he can’t hold still he’s admitting he can’t, he can’t hold it, cap please help, but cap KNOWS he won’t make it to the bathroom even if they try, so they just tell him to let go. it’s alright, it’s just me. and engies begging no, no he doesn’t want to wet himself in front of them, not again, please, please, he can make it, but caps so gentle and kind and when engie finally, finally lets go, he’s moaning with relief, legs giving out and cap having to catch him, and he’s shaking and arching into them for comfort and support and maybe he’s getting them a little wet too now but he’s too delirious in relief to notice, and cap doesn’t mind..... 😳😳😳😳

no need to apologize omg I'm adoring this

stubborn Engineer trying to hide obviously-wet pants; they’d rather deal with that than letting their Captain know they’d had an accident again… except it’s not hidden all that well and it really is making him uncomfortable and he realizes it’s just as childish to act like this than to just let the Captain cover for him while he gets a clean jumpsuit

and YES… the Captain encouraging him to let go where it’s safe, with them, rather than to try and fail and possibly be seen by others… and maybe just maybe leaning in and gently kissing his cheek as he wets, because he’s their engineer and they’re not going to be grossed out or put off by this. (Aaand maybe the relief in his eyes and blushing cheeks got them feeling some kinda way.) And maybe just maybe Engie’s takeaway being that this can feel good, too, if it happens where he feels safe with the Captain there to help him. 😳

[electronic-elevator]

oohhhh engie knowing he has to go, but he's an adult, he can hold it, its not that bad, and he won't!!! have another accident!!!!! he's fine!!!! the cap trying to gently nudge him about it but he wants to get this done, just this one circuit cap, I can do it, but then he's shaking and leaking so bad, and by the time he admits okay maybe he has to go, its too late and he's making a mess!!!! and he's so embarrassed but caps so gentle and helps him sneak to his quarters to take a shower znd get changed and they comfort him so well...... and ohhh the jumpsuits look so annoying to take off, so even if he makes it to the bathroom he's squirming and trying to get out of it, but he can't hold himself and undo the zipper, and he eventually wets himself in front of the toilet, half undressed, tears in his eyes........ 🥰🥰🥰🥰

I'm assuming these r from the same anon so I'm answering them 2gether <3

that jumpsuit is PERFECT for omo situations -- just complicated enough to stall them at that critical moment when they're standing in front of the toilet. You know, that point where your body knows you're SO close and your urgency spikes. >:3c not to mention that color hides absolutely NOTHING -- any substantial leak would be pretty obvious, if the rushed potty-dance down the hallway didn't already give them away

also the shaky sigh once he's finally done, standing in his own puddle -- disappointed in themself, sure, but so relieved...

Poor thing; I can't help but think his desire to be self-sufficient would be at war with his desire for the Captain's love and comfort.

Next time a day comes where they're kept separate, the Captain texts them reminders instead... bonus points if they're not subtle (and why would they be; it's a private line!) and someone sees one over his shoulder

[electronic-elevator]

cap seeing mark and gunther coming back from this scouting mission with wet pants and caps like ok mark i understand but gunther wtf and hes like I MADE A SACRIFICE FOR BROTHERHOOD and caps like what. gunthers a lil confused but he got the spirit. also imagining mack happens to be there when mark wets one day (nightmare world) and hes making fun of him, but doesnt realise the caps right behind him, who then puts a death grip on his shoulder and is like come into my office for a moment mack :)

LKJDSLJKFASDF we love a supportive, if overzealous, Gunther

ohhhhh my oh my, who's got Mack's next of kin on call... see I do love characters being humiliated, but I'd never hurt my beloveds, is the problem. so honestly having Mack around to hurt Engie... Not such a bad thing....

[electronic-elevator]

Engineer sleeping over in the Captain's bed... but they wake up before him and hear him, all flushed and breathy, moaning their title... still asleep, their hips stutter forward, seeking friction for their obviously-needy cock...

and the Cap has A Choice to make b/c 😳😳😳 even they can't deny that's pretty clear evidence of how their Engineer thinks of them, but it's also obviously not how he would've wanted them to find out (and they're on duty in like an hour soooo there's not exactly time to take this where the Captain would want it to go if yk what I mean)

[electronic-elevator]

(please tell me if im sending too many messages u would not BELIEVE how much ive thought abt markcu omo and had no one to share it with) i think illinois would be the most secure in his wetting. hes alone so much, he has no one to be embarrassed in front of, and he's in such isolated places, if he pisses himself, no one will know but him. him getting to a point of leaking, and he knows he isnt going to make it anyway, and his shorts are wet anyhow... so he just lets it go, moaning as he completely soaks himself...and i think he'd the most unashamed about enjoying it, able to tease himself with leaking slowly over an adventure, feeling himself lose control, legs shaking as he pisses all down his legs.... he KNOWS he loves it, and he feels no shame. but then when he gets a partner, he forgets he can't enjoy that so much with an audience, leaking purely on habit, and realising with a jolt that oh, god, he's not alone... but it somehow makes it even hotter, and he wants to see how far he can go... and engie likes it, but he's embarassed and a little ashamed of it, so he tries to rush into his quarters and wet there, alone and able to moan unabashedly, hand down his jumpsuit stroking himself as he pisses.... when hes desperate at his work station hes rocking his hips and flushed and trying to hide the line of his half hard cock in his pants..... noir and eric i think have to be assured by their partner that its okay, and that they actually *like* when they wet, and coaxed into enjoying it..... SORRY I THINK ABT THIS TOO MUCH AUGH

NO I LOVE these asks -- and I feel ur pain. like this isn't a Small Fandom by any means but god it feels like it sometimes

I could totally see Illinois into omorashi in general. 👀 highkey LOVE the idea of him half forgetting himself on one of the rare expeditions where he's NOT alone... and sure he might not be able to enjoy casually holding and wetting, but he gets the rare opportunity for there to be actual stakes to his holds...

yeah, Engie's in the "normal amounts of shame" zone I think jkldflsdf then Eric is just. poor anxious bby. needs a very gentle partner to show him he can enjoy it 😌

you anons have got me acting unwise (looking disrespectfully at sub!Noir)... kinda wanna keep him on the razor's edge -- not so coddling that he gets too comfortable with his wetting (b/c he's so damn cute when he's flustered and embarrassed) but not pushing him so far he'd try to hide it again or that it would come across mean and damage his love and trust 😈

[electronic-elevator]

engie starting to associate holding and wetting with the Captain and their touch, and now when they feel their bladder twinge their cock does too, and it's!!!!! mortifying!!!!!!! but it feels really really good!!!!!! one day when caps only texting him, stuck in meetings, he wets himself maybe probably only a little on purpose and strokes himself through his soaked jumpsuit, imagining its the captains hand........ bonus if cap sees him not responding to their reminders and gets worried and excuses themselves from the meeting to quickly check on him, finding him like that....... such pining fools.

oh NO... Engie panicking because they've failed step one (not wetting themself) and now failed step two (don't do something depraved)

stammering a breathless lie that he was only trying not to wet himself -- like his jumpsuit isn't tented with his need and like every fiber of his being isn't yearning to ask for the Captain's help with this, too -- but the Captain buying it because the alternative just couldn't be true, and maybe they're already in the habit of averting their eyes from that particular part of their Engineer to help limit those unprofessional thoughts, especially the ones that seem weirdly correlated to Mark's accidents 👀

[electronic-elevator]

[electronic-elevator]

engie rutting up into his soaked jumpsuit 🥰🥰🥰🥰🥰 whimpering and gasping for the cap and imagining its their hand, not his 😳😳😳😳 engie not knowing if he’ll cum or piss himself first 🥴🥴🥴🥴 he gets more and more secretive and having accidents on purpose in private, deliberately “””forgetting””” caps reminders so he can savour the caps attention on him and the pulse in his bladder going straight to his cock a little longer..... cap not knowing why he seems to be pulling away from them, worried, but engies just horny and trying to hide it (not well ofc) but when cap confronts him, so concerned and thinking they’ve upset him somehow, engie feels just so bad and has to admit to it..... cause the only thing worse than the cap knowing how gross he is would be the cap thinking he hates them..... and then maybe once they’ve both finally admitted their feelings and attraction, the cap can have mark squirming and grinding on their lap, trying not to leak onto his captain, but sooooo desperate..... 💖🥰💖🥰

🥴 ooo man Engineer purposefully evading Cap's earnest, helpful reminders b/c he's found he likes holding it?? OOOO

this got long af so

Engie feeling guilty about it, but oh god their release is just so much sweeter when they think about the burn of their cheeks when they have to admit to another accident, about the Captain's sympathetic face as they promise him it's okay... the first red flag is that all of a sudden Engie wants to clean themself up, and little does the Captain know they're getting off in their wet jumpsuit first >:3

orrr hurrying away "to use the bathroom," but after locking himself in his quarters or a private stall, unable to resist touching first -- stroking their cock while squirming in front of the toilet they could use at any time, and wetting as soon as they've cum; piss trickling down still-shaking legs as they stifle their moans with their only clean hand. having to report that he didn't make it -- which isn't a lie, but it's also not really the truth

it can't continue forever, though; for one, when Engie's head is actually clear he feels awful about it, but the Captain is so sad that he seems to be pulling away from them again that they're the one to bring it up first, and then Engie is HORRIFIED and just has to admit he's come to like the feeling but that he's so fucking sorry for basically using them like that. promising not to do it again, not to involve the Cap anymore even with his legitimate issues, but Cap interrupting like NO please let me keep doing this for you I WANT to do this for you. probably not outright admitting they'd guiltily pleasured themselves to the same idea in reverse but not denying that their interest in helping him with this may not exactly be platonic either

it's an AWKWARD encounter and Mark still avoids Cap for a few days. forcing themself to actually use the toilet when they need to go, as soon as they need to go, and changing themself with no fooling around if they don't make it. (they can't stop the direction their fantasies turn in the evenings, though...)

but... god, he misses the Captain, so it doesn't take too long before he's accepting invitations to lunch again; seeking them out to watch a movie or just to talk after work hours. and of course, if they're together, the Captain will cover for him so he can get to a toilet on time or go change; will offer to bring him dry clothes if he needs

(ok. an aside. picture Engie w/ his jumpsuit rolled to his waist, tied so the arms just mostly cover the evidence of having leaked for long enough for him to get back to his room. that sleeveless turtleneck meaning people are probably Not going to be looking at the wet patch anyway...)

...but maybe they've stopped reminding him to go, if only because they still feel awkward. And maybe one night Mark's infodumping about something, and the Captain notices he's dancing around in that tell-tale way, but... they don't say anything like they would've done just a couple weeks prior.

Something makes the Engineer catch up with himself, though. maybe he leaks; the sudden wet heat breaking his concentration and bringing him to a stammering halt. "H-hey I, um, need the bathroom; I'll be right back," he admits, blushing, but before he can make a run for it, the Captain can't help but stop him.

"No, don't go yet."

"C-captain?" Engie would stammer -- forced to bend over and hold themself just to keep from leaking again. The Captain hasn't ever delayed him from the bathroom before. But how many times has Mark fantasized about it? They're alone, but in a public area of the ship -- not exactly appropriate to just... wet himself in. Not that a logical thought like "appropriateness" was left in their head. Their cock was stirring, adding to their humiliation.

"Hold it," the Captain instructs, a little uncertainly. "I want you to. And... you like it, don't you?"

Engie nods, ashamed. "But I-I'm-- I'm not going to be able to. Not for long."

"I know," the Captain whispers, and Engie is somehow shocked to hear the lust in their voice. "But I want to see how you try. Tell me how it feels."

The Engineer swears under his breath. "Really bad. Er, I-- I need to go really bad. It feels... good. Fuck, Captain, I can't think straight; I don't know."

The Captain wanted to press him further but he yelps and adds, "Fuck, I leaked again-- Cap--"

The Captain can see the evidence, this time, even past the Engineer's clutched hands, and openly stares at the glistening patch of fabric running down Mark's thigh. "Does it feel better when you hold it to the very end?"

The shame runs hot through Mark's body as he shakes, trying so hard to regain control. "Yeah," Mark whines. He's never done this on purpose with someone else -- let alone the Captain -- right there. So close. And little leaks keep spurting out of him. "FUCK. I can't-- can't control it."

"Just keep trying; you're doing so well."

Mark is shocked by the effect the simple praise has on them -- their cock twitches and they whimper, and at the same time, they feel calmer -- no less frenzied, but safer. "T-thank you, Captain... Could you-- fuck, say that again? Please?"

"Say what?"

"That I'm good," Mark whimpers. All his squirming is getting him awfully close to that point where his need to cum rivals his need to piss.

"You're so good, Mark... holding so much in; I know that's hard for you... and letting me see you like this. So desperate; you're so pretty."

Mark whimpers again. The logical part of him, still banished to the deep recesses of his mind, knows they have GOT to talk about this -- about them -- at some point. But, oh, his Captain thinks he's pretty when he's about to make a mess of himself like this.

Really, he already has; he's soaked down to his knees from all the leaking.

"Captain," Mark pants. He's fighting to keep holding -- he'll do anything if his Captain asks him to -- but there's just no way to keep it up; his weak bladder gives out. "G-gonna-- oh f-fuck, I'm peeing--!"

The Captain's eyes widen; the hiss of Mark's pee and pattering of it soaking through his jumpsuit then onto the floor is surprisingly loud in the quiet room, and Mark's moan makes their own arousal twitch. "Fuck, Mark... holy shit." The Engineer's next sound is more distressed, and the Captain remembers to add a reassurance: "I-- just let it out, love; that's alright; that's perfect..."

And neither of them are too sure who moves first -- bridging the few inches left between them to finally kiss, wholly unconcerned with the state of Mark's clothes
