Lime scurried through the vents as fast as their body would take them, frantic thoughts racing through their mind. They’d seen it, they’d seen it with their own two eyes, and they needed to find someone, to tell everyone that—
That Blue was an alien.
They hadn’t even suspected them, really. They’d trusted Blue, they were the only one Lime trusted, in fact. If anything, they’d suspected Orange or Green, or maybe Red. All of ‘em were too-friendly Mira corporate shills, meaning they were either brainwashed sheeple or brain-eating aliens. They’d just been moving through the vents, trying to find the reactor room. They had to deal with all the mechanical shit from being the engineer, not that they would trust anyone else with it.
They’d only headed over to the lower engine after hearing some odd noises from the area. They’d raced over to it, thinking maybe one of those gremlins had snuck on the ship. They had to catch one of em, otherwise they’d go through the ship making everyone fall in love with them!
“I’VE GOTCHA, Y’DAMN GREMLIN!” They yelled, popping out of the vent. They looked around, letting out a horrified gasp at what was in front of them.
Oranges dead body, still upright, their face ripped off. Their body limply sunk to the ground, a dull thumb accompanying it. A writhing mass of tentacles and limbs stood before them, turning slowly to look at Lime. Blues face stared back at them, their usual warm, sweet expression replaced by cold apathy. The creature— no, Blue, stared at them, their two sitting in silence. Lime felt frozen, like the world was melting around them and Blue was the only thing that existed. Their heartbeat hammered in their ears, body shaking in fear.
Blue shifted out of their monstrous form, shrinking into a human as if nothing had happened, the only remnant of their deed being a smudge of blood on their cheek. They began walking towards Lime, their gaze focused on them. “Ah, Lime,” They started, voice calm, as if they were talking about the weather. “I didn’t expect you to be-“
Limes adrenaline kicked in and they quickly dipped back into the vent, crawling frantically through the passages. If they could get to the cafeteria, they could call a meeting, but would anyone come in time? They didn’t know where anyone was, dammit—
They heard the vent behind them open, something was following them. Blue was following them. Shit, shit, shit—
They began cursing themselves for not carrying around a map. Their memory was usually good enough to traverse the vents fine without a reference, but when they were panicking about a shapeshifter-alien-thing following them, panic took over rational thought.
The multiple twists and turns only confused them more, not helped by the fact they could hear Blues voice echoing in the tight passageways. Telling them to calm down, that they could talk about this— and bullshit to make them an easier victim. They’d only looked back for a second, just to see how close Blue was, where they promptly ran into a wall, slamming their side into the vent.
Fuck, fuck, a dead end. Awesome, great! Just their luck. They turned around and sat up, pushing their back against the wall, seeing pink tentacles begin to catch up with them. Great, they were going to die in some dusty vents where nobody would find their body, and they’d never even baptized anyone yet!
It wasn’t long before they were face to face with Blue. Lime shrunk back, gritting their teeth and shutting their eyes, preparing for the worst. Of course this would happen when they started trusting someone, God they were such an idiot—
“Lime, would you look at me?” Blue asked. Limes eyes shot open just from the oddness of the question. Why would it matter to a killer alien if their eyes were open??
“What, ya wanna look me in the eyes as ya kill me? Sick fuck.” Lime questioned, trying to keep the tremor out of their voice. “No, no, nothing like that. It’s just hard for us to talk if you’re cowering in fear like this.” Blue clarified, cordial as ever.
“Wh-?! What is there to talk about?!” Lime snapped, arms emoting in a desperate attempt to convey how taken aback they were. “You’re a murderer! Ya killed Orange! You’re gonna kill me next!”
“That’s not necessarily true.” Blue stated, “You don’t have to die here, Lime.”
Lime blinked. They looked around, as if there would be cameras and someone would pop out telling them this was all one huge prank. Because seriously, there was no fucking way this was real. “What kinda trick are ya playin’ here? Whatever it is, I ain’t fallin’ for it!”
Blue tilted their head, “Always so vigilant. But there’s no trick here, really. I would just prefer not to kill you.”
Prefer. Not off the table, they’d just rather not. But why would they want to keep Lime alive, even after they knew their secret? It was just some freaky mind game, they’re sure. It didn’t mean anything.
“So what? You’ll just kill the rest of ‘em, even if ya don’t kill me! I’m onto ya dammit, so don’t even try t—“
“Why do you care?” Blue interrupted them, the question blunt and cold. Lime tensed at their tone, and then their question. Of course they cared! What kind of question was that?
“What— what are y’even—“
“They don’t care about you, Lime. You may want to deny it, but you know it’s true.” Blue inched closer to Lime, tentacles pulling them forwards. “They all suspect you. I hear it all the time. Because you go through the vents, because of how off-putting they find you, because you’re ’crazy.’”
One of Blues tentacles slithered towards Lime. Lime braced themselves for the worst, gritting their teeth, but instead of a slash, it caressed their face, the cold wetness from the appendage staining their face. They shivered at the sensation, their head beginning to feel fuzzy.
“But I don’t find you crazy. You know that, don’t you? You can trust me, Lime.” Their voice was low, sultry, the sound making something stir within Limes guts. They were so close, too close. Lime felt like their heart was going to beat out of their chest, thumping wildly in their ears. Blue smiled, undeniably sinister, and yet…
Two more tentacles sprouted out of their back, grabbing Limes wrists and pinning them to the back of the vent. Lime struggled against their grip, but they were too strong. What were they feeding these damn aliens anyway?
“Don’t worry Lime. I don’t want to harm you, like I said, you can trust me.” Blue assured them, tilting their chin upwards with a tendril not restraining their wrists. “Bullshit.” Lime grumbled. “You’ve just been buttering me up so y’can kill me easier, huh?”
“If I wanted to kill you, I would have done it already.” Blue said bluntly. Lime couldn’t really argue with that, so they stayed quiet. “I like you, Lime. You’re the most interesting one here, not like everyone else. I tell them to do whatever and they’ll listen at the drop of a hat. I say jump, they’ll ask how high. Why do you think it was so easy to kill Orange?” Limes stomach turned at those words, hearing how uncaring Blue was about all this, to the damage they caused. The tentacle at their chin moved downwards towards their chest, slipping underneath their clothes to their bare chest. Limes breath hitched, their face reddening.
“Not you, though. You’ve got a brain in there, don’t you? You’re an equal.” The tentacle ghosted over Limes nipple, and the engineer couldn’t help the shudder that escaped their lips. They felt their boxers dampen at the feeling. “S-Stop beatin’ around the fuckin’ bush. Say what y’mean.”
“How do I put this,” Blue murmured thoughtfully, putting their hand on their chin. They snapped when their words reached their head, humming. “I like your smarts, that’s why I would like to fuck them out of you.”
Lime sputtered, words lost on them, face heating up with blush. Blue being an alien was one thing— insane, terrifying, will probably do horrors to Limes already preexisting trust issues, but whatever. Not whatever, but whatever. Blue being an alien who wants to bang Lime instead of just killing them was a whole other thing. Unbelievable, suspicious, and maybe a little hot. Maybe. Just a little.
“You’re— you, you’re fuckin’ crazy.” Lime muttered, turning their face away from Blue. “And what after, huh? I know your secret, I could just tell everyone about ya and get ya thrown off the ship.”
“You could. But you won’t.” Blue asserted confidently, suavely, “Because you know what I said is true. And after all…”
“Between you or me? You know who they think is more suspicious.”
Lime bit their lip, glaring at Blue. They stared back smugly, like they knew what Lime was going to say. That asshole.
“Fine. Stupid freaky alien.” Lime murmured, and Blues grin widened. They removed all three tendrils from Limes body. Lime only had time to be surprised for a second before Blue grabbed them by their midsection, flipping them over. Lime grunted as their face pressed against the vent wall. They weren’t sure if Blue was able to do that from their natural strength or weird alien mumbo jumbo, and they weren’t sure which option turned them on more.
“Ah, my apologies. I should have warned you.” Blue apologized, their tentacles pulling off Limes overalls. “You’re fine killin’ people, but that’s where y’draw the line?” Lime scoffed, rolling their eyes. “Yes, in fact.” Blue confirmed, as if it was totally reasonable.
Blue pulled down Limes boxers, one of their tendrils sliding over Limes pussy. Lime shivered, the cold, wet appendage causing goosebumps to prickle on their skin. “You’re already wet and I’ve barely even touched you.” Blue teased lightly, dragging the tip of their tentacle up and down their cunt. “And I thought you hated aliens, Lime.”
“I do, it’s just, j-just, mnh,” Lime let out a shaky breath, steeling themself. “You’re just persistent.”
“Am I?” Blue questioned, the tentacle slipping in between their folds. Lime couldn’t help the way they gasped, covering their mouth with their hand quickly after. “You’re pretty hard to convince, Lime. For you to have gone along with this, you can’t possibly have hated me that much.”
Lime was dripping before long, legs trembling slightly. Blues hands gripped Limes waist while their tentacle squirmed and prodded at their cunt, its own moisture mixing with Limes slick.
“Are you a virgin, Lime?” The doctor asked casually, like Lime wasn’t flustered out of their mind already. “Shit, why’s it matter anyway…Are all y’aliens fuckin’ perverts?” Lime scoffed, not-so-secretly wishing that tentacle was inside of them already. Blue snickered, choosing not to answer. That was another thing to add to the conspiracy, Lime guessed.
Their tentacle slipped inside of Limes hole, causing a moan to escape Limes throat. The tendril was so cold, the contrast between it and Limes warm cunt sent waves of arousal through the both of them. The tendril seemed to explore their insides, squirming inside of them, touching every crevice of their pussy. Lime barely touched themselves as is, always too busy fighting off chem trail fumes or gremlin spores. This was so different, too different, too good.
“You’re so tight, Lime…I suppose that answers my question from earlier, hm?” Blue taunted, pushing the tentacle deeper. Lime half suppressed a moan, their hand still desperately covering their mouth. The tendril began to thrust in and out of Lime, their pace already fast. It pushed deep inside of them, its natural lubricant and Limes sopping cunt making the stretch easier.
“Fffuck, Blue, wh-what the fuck—“ Lime muttered, brain struggling to come up with rational thoughts, or any thoughts that didn’t have to do with the fact a killer aliens tentacle was in their pussy. “Don’t turn all dumb too quickly, okay? I want this to be fun.” Blue said evenly, their tendril thrusting harder inside of them. “Speaking of…”
Another tendril sprouted out of them, grabbing Limes wrist once more, ripping their hand away from their mouth. “Don’t hide your noises from me, I want to hear you.”
Lime whimpered, mumbling curses under their breath. They flinched at the sensation of something else nudging their entrance, feeling the tentacle already inside move to accommodate it. “Fuckin’, what are you doING-!” They were cut off by their own yelp, another tentacle plunging deep into their pussy. Their cunt spasmed around the appendages, both fucking them in tandem.
“Don’t worry, I’ll take care of you.” Blue assured them, curling their tendrils inside of them. Tears pricked in Limes eyes, broken moans spilling out of them. Blue hummed as more slithered up Limes body, two latching onto their nipples, the extra stimulation driving Lime mad.
They hated Blue, they hated Blue so much. Hated how they knew so much, how they knew what Lime was thinking before they said it. Hated their stupid, seductive voice, the way they teased them when they were like this, hated how wet it all made them, fuck. They couldn’t stand them.
“Too much, Blue, fuck-“ Lime stuttered, cunt twitching with need. “I’m gonna, g’na, God-“
“You poor thing.” Blue purred. “You’re so close, aren’t you? Want me to come with you?” They leaned over, their chest against Limes back. “You want me to breed you, don’t you? Want me to pump my eggs inside of you, fill you with my kids.” Blue whispered, smile widening when they felt the way Limes pussy clenched around their tentacle when they spoke. Their grip on Limes waist tightened possessively, all too satisfied with their work thus far. “Hhhah— s-stop fucking talkin’, God—“ Lime bit back, lacking any edge.
“It’s okay, I’ll give you what you need.”
The tendrils started fucking Lime harder, slamming into them with reckless abandon. Lime sobbed out moans, any words they tried to say turning into incomprehensible whines. Their cunt tightened hard around Blue, slick gushing out of their pussy. Blue fucked them through their orgasm, not giving them a second of reprieve from the onslaught of pleasure.
Lime shook from the aftershocks once their orgasm was over, body trembling like a leaf in the wind. They still felt so full, Blues tentacles not having left their insides for a second. They’d distantly noticed that Blue hadn’t actually come yet, which led them to a very short lived mental rabbit hole on if whatever species Blue was even orgasmed.
It was quickly cut off by Blues tentacles thrusting in them once again, making Lime gasp in a mix of shock and pleasure. “Wh-hhah— what’re y’doin, hnmh-!” Lime turned back, brows furrowing at the smug look on Blues face. “I told you, Lime, I want to fuck you stupid. And considering you’re still capable of forming words right now, I haven’t quite reached my goal yet.” Blue responded evenly, like Lime wasn’t a mess under them right now.
Lime mumbled under their breath, something about Blue being a perverted asshole, but it quickly turned into desperate whines. Blue snickered to themselves. They’d need to make up some excuse to tell the crew on why they’d been gone for so long, but this was worth it.
. . .
Lime had long lost count of how many orgasms they’d had by now, not helped by the fact they could barely form a rational thought. Tears stained their face, body so sensitive they felt like they were losing their mind. Each thrust into their pussy sent a shiver down their spine and more slick gushing out of their hole, their mind completely gone.
Blues hands had moved, one holding Limes chest while the other held onto their waist. They drank up every little noise Lime made, the sounds of their overstimulation like heaven in space. They opened their mouth, their long, inhuman tongue snaking out and licking Limes neck. Lime shuddered at the feeling, another whine escaping them. They couldn’t stop themselves from orgasming once more, their words slurred and desperate, the only clear one being Blues name.
“You really are something special, Lime. Such a catch….Maybe I should just keep you, you’d like that, wouldn’t you?” Blue grinned, feeling themselves reach their own peak. “Keep you all the time, fuck you whenever I want, fill you with my eggs…Sounds nice, doesn’t it?”
Limes cunt weakly clenched around Blue, their hole tired from so many rounds. “B-Blue, God, please…” They whimpered, their usual attitude having been fucked out of them. Blue pumped their tendrils in a bit more before pausing abruptly, tentacles curling deep within Lime. Lime felt one of the tentacles bulge inside of them, like something was passing through it. They jumped when they felt an egg slide into them. It wasn’t big or anything, in fact, they’d expected the whole ‘alien egging process’ to be a lot more unenjoyable, but still. Lime shifted, whining at the feeling.
“Don’t move too much, it’ll be more uncomfortable that way.” Blue warned, peppering kisses onto Limes neck. Lime grumbled, tensing up when another egg was pushed into them. “And don’t you worry. I know you’re not very capable of speaking right now, but I’ll take these out of you soon. I just want you to feel them inside of you.”
More eggs were steadily pumped into Lime, each one making them feel more full than the last. Blue pulled out of them once the last one was nestled deep inside of them, their tendril covered in Limes juices. Their tentacles receded back into their body, and Lime would be curious on how it worked, but they were pretty sure they were about five seconds from passing out as is. They were so sleepy, all the energy drained out of them. It was comforting, in a way. They could seep all this off and not deal with the absurdity of the situation until they woke up.
“I hope you enjoyed that as much as I did.” Blue smiled cheerfully, “I’ll have you on a hospital cot soon. The others will think you’ve simply come down with an illness and that I was taking care of you.”
“I must be fuckin’ sick if I went along with this…” Lime slurred, lulling into a deep slumber. “Y’musta used some…Weirdass creature mind powers on me...” Blue chucked, “Not quite our area of expertise, my dear.”
Blue stayed with Lime until their let exhaustion take them, snoring softly. Blue moved their body out of the cramped air vent, listening out for any crewmates on the surface. They assumed they were far enough from any open vents for the rest of the crewmates to hear them, but they really didn’t know the layout as well as someone like Lime or Green. Oh well. Still, even if someone had heard, it’s not like they’d really be able to explain it. They were off the hook for now. Probably. Maybe.
It didn’t matter right now. They climbed out of the vent, holding Lime in their arms. They laid them down on the cot, smiling warmly at the way they cuddled up into the pillow. They retrieved some napkins and water, wiping Limes face off with the napkins and keeping the water on the counter for when they woke up. Blue stared lovingly at Lime as they slept, and they felt so lucky to have Lime all to themselves. They knew they were right to convince Green not to kill them.
They turned away, leaving Medbay to meet with the rest for the crew. It was about time to use that excuse they’d been cooking up.
