The vent creaks and squeals, struggling from the pressure it experiences. Green's soft body squishes through the tight space and grimaces at the discomfort it brings. They were sneaking into MedBay, hoping to have their first target be Blue. It would be them that would easily be able to figure out that they were aliens after all. That stupid device, if everyone was required to be scanned, they would be caught in no time, and they can't have that happen. Orange also seems less interested in killing, which is unfortunate because that's the best part!
They hear a familiar voice with the next turn they take; the thrill of a predator hunting its prey seeping in. Crawling up through the opening, they gently peek through the vent, hungry stare landing on their target. Green climbs out of the vent, being as careful as possible as they approach Blue from behind. They seem immersed in some sort of document, not that the impostor cared really. Tentacles sprout from their flesh the closer that they get, and a toothy grin splits open in the middle of their torso. Green tastes the air with excitement, anatomy preparing to strike.
Just as they're about to go in for the kill, though, the printer beeps, and they jump. Blue makes an “ah” sound and carefully places the paper down before turning around. There's no time for Green to even think about returning to their inconspicuous form.
“Green! When did you get in here?” The doctor asks, and Green simply stays frozen, their mind panicking. Blue seems confused until they actually acknowledge the other's appearance, visor contorting into a worried expression.
“Oh my, are you sick? What is with these weird appendages growing out of you?” Concern fills their voice, and Green's chest flutters. Pretty is all that fills the impostor’s mind, feeling themselves flush as if it was the first time that they saw the doctor again. They snap out of it, their peripheral exposing the open door. They'd need to come up with an excuse and fast.
“Actually uh… yeah I am feeling kind of sick, that's why I came in here.” They finally respond. Blue lights up with confidence and grabs their hand, dragging them to one of the medical beds.
“Not to fear! I will help you figure out this mystery illness; you'll be back in shape in no time.” Green reluctantly follows the eager pull, sitting on the bed when motioned to. Blue moves their hat and pets their head, ruffling their fur. The impostor purrs happily before quickly muffling themselves. Swiftly turning around, the doctor looks for tools to diagnose them.
“I'm just going to run some tests to figure out what's going on, okay?” Blue states, rummaging through the various cabinets. The other pays them no mind, stuck in a daze as their skin burns.
Pretty doctor. So pretty.
No! You're supposed to be killing them! Their mind screams, and they shake their head, trying to expel the entranced thoughts. Blue returns to the bedside with a thermometer in hand and checks the temperature of the other. Shock lights up their face at the result.
“You're absolutely freezing, Green! Let me go grab some blankets for you.” Blue quickly runs to the blanket shelf, stride confident and unbreakable. A feeling inside Green’s chest swells, though they can't exactly pinpoint what that feeling is.
“Actually, I feel really wa-”
“Nonsense! Trust me, my friend.” The doctor cuts them off, carrying three of the largest blankets available back to the other. Embarrassment creeps back in again, mind foggy and skin tingling as they are thoroughly tucked in. They aren't sure if the oppressive heat is from the blankets or if it's because of their proximity. A shiver goes down their back when Blue gently grabs one of their tentacles, carefully observing it.
“What an interesting ailment…” They trail off curiously, mentally imaging each anomalous property. Green blushes again as their impostor form is practically fondled with curious yet loving hands. Each touch is light yet memorable; it's oddly intimate, actually. Well, at least Green feels it that way. The tentacle squirms in Blue's grasp as if it has a mind of its own.
“Do these move independently without your own input?” They ask, mind set on figuring out the mysterious illness.
“Yes, and they're also,” Green pauses as they observe their tentacle stretch out to lightly caress the doctor's visor. They slap it away before it can cause themselves any more unexplainable feelings. “very friendly.” They finish, mentally straining themselves to not touch the gorgeous crewmate in front of them.
Stupidly attractive. Unfair.
“I see.” Blue simply responds and lets go of the appendage; Green misses the contact already and bites down the whine that nearly slips out. The sound of footsteps approaching from the hallway has panic kicking in, and Green forces themselves to revert to their crewmate form.
“Blue!” Red shouts cheerfully while approaching the two. Concern spreads across their visor when they notice that Green is sitting on the medical bed, appearing as a patient.
“Are you feeling okay, buddy?” Green attempts the most uncomfortable expression they can at the question.
“Yeah, just feeling a bit… queasy.” They emphasize this by appearing as if they're about to vomit; the act works.
“Don't worry Red, I'll be sure to take great care of them.” Blue chimes in, resting a hand comfortably on the captain's back. Jealously claws at Green's heartstrings, and they let out a growl before they remember to silence themselves. Thankfully neither of the two notice, and they mentally sigh in relief. What was getting into them today?
Charming and smart and handsome, need to keep as a pet. All mine.
What?!? They yell in their mind; this was not the time!
“Oh, by the way,” Blue pauses, gesturing to Red, whose attention is now thankfully on them and not the absolute mess that is Green right now.
“I found some interesting readings with them that you might want to hear about.” Horror swirls in the impostor's gut, and they quickly lean over to slap a hand over Blue's visor.
“Don't you have patient confidentiality to follow?” They laugh awkwardly; it's definitely suspicious and not entirely convincing. Of everyone, they're glad that Red was the one who walked in, though. There's a certain look that Red gives them, but Blue raises a finger in acknowledgement and nods.
“You're absolutely right, Green; my apologies. Sorry Red, I'm not allowed to disclose that information without consent; I do hope you understand.” Red doesn't seem entirely convinced but drops the topic anyway, moving to leave the room.
“Alright well, I hope you feel better soon.” They wave as they reach the doorway and Green musters a thankful expression, visor brightening warmly. The doctor waves back in response but remembers something before the captain leaves and stops them. Green wants to forcefully strangle them with their own intestines the longer they stay in here.
“Oh, could you close the door so no one else comes in here? Thank you.”
“Noted.” Red responds, giving a thumbs up before closing the door and leaving. The impostor lets out a breath they'd been holding for way too long and relaxes. That was way too close.
“Now where was I…” Blue mumbles, turning and walking to the testing station. They had pulled out a wide array of tools, most of which Green didn't recognize. Impatience kicks in; now would be the time. But what if Red remembers that they were the last person with Blue? That would surely blow their cover.
I want to eat their face.
The rope snaps
“I can't keep up this act anymore.” Green sighs out as their body splits open, monstrous form emerging. They pounce at the other, grabbing them with one of their tentacles. The doctor gasps as they're forcefully squeezed with the appendage, and Green's maw drips with saliva as they lick their sharp teeth with their tongue, preparing to strike. Blue simply peers at them; there's no fear. Actually, there's nothing at all. Confusion swirls in their mind as they stare at the other before their hold weakens and they start to shake. They continue to look at each other, vision locked in a stalemate before Green groans out in frustration.
I can't do it.
“This is kind of hot, you know.” Green chokes and nearly drops them, recoiling at the statement.
“What?” They respond in utter disbelief, visor widened in shock. Blue's gaze switches to charming, and they run a finger down the length of the tentacle that's holding them in place seductively. The pleasant shiver that runs through their entire body makes them want to beg.
“What a remarkable specimen, I knew there was something different about you when we first met. Why don't you put me down and let me reward you with something for being good?” That familiar trance returns, and Green feels themselves succumbing to the unmatched charisma. Their mind feels foggy, swimming in a thick ocean of honey as they gently set the doctor down, mesmerized and swaying in the process. Blue grabs the collar of the hoodie, and Green follows easily, matching the level of the doctor. Their visors touch, and the impostor blushes as the mouth on their body forms into a lazy grin.
“Good job.” Blue praises, pressing their palm into the side of Green's face. They lean into the touch happily and purr; if Green knew any better, they would probably think they would have been bewitched. Enchanted and enamoured by the touch and praise, their body practically melts under the affection. Blue pushes their head down further, hat lost and forgotten at some point. Not that Green cared really. The resulting sight has the impostor drooling, forked tongue lolling out of their mouth.
Need to… taste…
“Go on.” Blue encourages, fingers lightly grasping the impostor's fur. They waste no time, tongue shooting out to taste the tip of the doctor’s semi-hard cock. The groan that slips out into the air is addictive, as well as the taste. Green feels drunk and also painfully aroused, their own anatomy sliding out and dripping on the floor beneath them.
“That's it, so good for me.” Green keens under the words, tongue curling around and squeezing the tip. The sensitive flesh hardens within seconds, and they can practically feel it pulsing. It encourages them more as they wrap further down the shaft, stroking it, milking every bit of that delicious substance that makes them go insane. The moans from above are music to their ears as their thoughts float above the clouds, knowing nothing more than to just be good and take it. Blue thrusts their hips into the wet coil, gripping the strands harder. The thought of being used as a toy makes Green whine uncontrollably, and they speed up the pace of their strokes, leaking pathetically under the watchful guise of the other. Blue's visor is squinted, contorted in a concentrated yet loving expression; it made Green's heart swell.
“Doing so well, what a good little creature. All mine.” Blue pants out. The whimper that Green lets out is heavenly, and they leak even more on the delectable tongue. Green wants to touch themselves so bad, the aching arousal burning inside them.
Must be good. Listen to the pretty doctor.
They try to express their want with an innocent expression, visor brightening and widening as they look up at the other, equivalent to puppy eyes. The result causes Blue to flush at the sight, thrusts stuttering inconsistently. It doesn't give them the response they wanted, but seeing the amount of bliss they could give someone with their body was inspiring. They snake around the cock even further, wrapping and tightening around the balls. Blue gasps as their release rapidly approaches.
“So close, do you want it pup?” It's a rhetorical question, but the pet name and excitement has Green nodding uncontrollably. They speed up the strokes of their tongue even more, salivating and ready to drink up every last bit of that divine liquid that they've oh so patiently waited for. The next thrust has Blue groaning their name, cumming over the wet muscle. Green makes a stupidly cute squeak and laps up every drop of spend before the doctor becomes oversensitive and pushes them off, much to the other's disappointment. Blue scratches the head of the impostor again lovingly, softly laughing and savouring the purrs that fill the air. So cute.
Maybe Orange was right; killing might not be the most fun part after all.
