Work Text:
Getting to work on the Nemesis was an honor you couldn't believe had been bestowed upon you.
You were a technician in the Decepticon military, but not a particularly high-ranking one. Despite your specific field being highly specialized, it wasn't commonly needed and you usually found yourself stationed at some remote site that had the equipment you were trained to work on.
Equipment that had recently been brought on board the Nemesis. As it turned out, you were the only Decepticon known to still be alive who knew the complete ins-and-outs of this stuff. Apparently the other candidates were known to have been either deactivated or were MIA.
Something you couldn't help but notice upon your arrival was that all the officers were very attractive. You wondered for a moment how it just so happened that all the hottest Cybertronians in the Decepticon army ended up on Megatron's flagship, until you caught him ogling Starscream's aft and wondered no further. He had good taste, that was certain.
Megatron may have had his favorite, but you had yours. Oh, the things that cherry red medic and his burly blue assistant did to you. Knock Out was aptly named, curvaceous in all the right places with hips that swayed when he walked. His voice was like liquid velvet to your audials, with a lilt that always suggested something more sensual behind whatever he was saying. Then there was Breakdown, the absolute ideal of mechsculinity - A big, broad chest and thick limbs perfect for bashing Autobot helms in, but a mech of amicable and empathetic nature amongst his own. And that handsome, chiseled face that made you weak in the leg-struts. Oh yes, you definitely had a massive crush on these two.
Which made it all the more difficult to visit the medbay when an extremely embarrassing medical issue reared its ugly head.
You'd been trying to ignore it for almost three days now, convincing yourself it would go away on its own despite the discomfort. When mere discomfort gave way to painful cramping in your lower abdomen is when you finally decided you needed to get this dealt with, and hopefully not die from humiliation in the process.
You approached the medbay, unsure if you were supposed to knock or just walk in. Playing it safe, you chose to knock and heard that sultry voice beckon you with. Taking a deep vent to calm your nerves, you walked in.
Knock Out was organizing a bunch of vials of... something, while Breakdown was sterilizing equipment nearby. Knock Out looked up at you. "Ah, I was wondering when the newbie would pay us a visit. To what do we owe the pleasure?"
You grimaced as a cramp hit you, clutching your abdomen. "I've - ah - started having pretty bad cramps in my lower abdomen."
He sighed. "What a shame, and here I was hoping this would be a social visit."
"You were just hoping we wouldn't have to do any real work." Breakdown teased.
Knock Out placed a hand on his chest in mock offense. "Moi? Never, I just wanted to get to know the newbie better. Speaking of which," He turned toward you and gestured to a medslab. "Go ahead and have a seat."
You sat down on the medslab, and Knock Out and Breakdown walked over. Breakdown had a scanner in hand and turned toward you. "So, abdominal cramping, huh? That can't be fun."
You winced. "No sir, it really isn't."
Breakdown gave you a flummoxed look while Knock Out barked out a laugh. "Megatron is the only "sir" around here, you can just call Breakdown and I by our names."
That was good to know, and it did put you slightly more at ease. You had a suspicion though that you could never get away with calling Starscream anything other than "Commander."
Knock Out continued. "Now then, abdominal cramping could be a lot of things. Do you have any other symptoms?"
Ah. There it was, the question you'd dreaded answering. "Um... I can't void my waste tank."
"And how long has that been going on?"
"Uh... almost three days?" You replied meekly.
Shocked stares met you as they simultaneously replied with "What?!" and "Three DAYS?" Knock Out frowned at you and asked "Why in the world didn't you come in sooner?"
You hid your face in your servos. It was very un-Decepticon-like behavior, but being chided was somehow even more embarrassing than just your specific medical issue. "I'm sorry! I was embarrassed!"
Breakdown shrugged. "Eh, you're here now, I guess. Lie back and I'll scan ya."
You laid down, and Knock Out began to speak as the scanner beam swept across your frame. "I have a pretty good idea of what the main problem is, but we'll know for sure when the scan is done."
After a few moments, the scan finished and a high-resolution diagram of your innards appeared on the console screen next to the medslab. It only took Knock Out a glance to immediately point out the problem. "See this?" He pointed to a moderately-sized tank in your lower abdomen. "That's your waste tank. It's completely full right now because the pipe connecting it to your external nozzle is being pinched off. And this-" He pointed to a small but swollen-looking sac in your pelvic area. "Is the culprit. That's your transfluid sac, and it's become so overfilled it's blocking off your waste tank. When was the last time you had a spike overload?"
Whelp. Time to die of humiliation, because there is no way in hell you're about to discuss your masturbation habits with your crushes.
As though reading your mind, Breakdown gave you a sympathetic look and said "Look, I know it's embarrassing, but you gotta work with us."
"I, uh... don't use my spike much. I prefer my valve."
Knock Out shot Breakdown a smug look as if to say "I knew it," but maybe you were reading too much into the intentions of the mechs you were crushing on. He looked at you and said "Having a preference for your valve is perfectly fine, healthy even. However, in the interest of preventing this from happening again, I do recommend having a spike overload every so often. It'll make it less likely for you to get, ah, 'backed up.'"
You hid your face in your hands as a bright blue blush tinged your face. "Oh... okay."
Knock Out adjusted the medslab so that the end split down the middle, separated, and bent at your knee joints; forcing your legs up and apart. "Breakdown, be a dear and get a catheter and a collection bag. Oh, and one of the beakers while you're at it."
Breakdown was on the other side of the room when he called out. "Do you want the 5" or the 6" catheter?"
Knock Out hesitated for a moment, the replied "The 5" one." He continued but looked down at you as he spoke, a subtle smirk crossing his features. "Big enough for quick drainage, but not so big it'll hurt our patient."
Now that got your attention. "Yeah, yup! Pain-free would be great, actually." You said nervously.
Knock Out chuckled and his smirk morphed into something gentler. "Oh, you're adorable." You weren't sure your face could get any more heated.
Breakdown returned with a tray of supplies and Knock Out began to explain the procedure to you. "We're going to insert this catheter into your waste nozzle, which will allow the waste fluid to drain into the attached receptacle. It won't be comfortable per se, but it shouldn't be painful. Now, then." He tapped on your pelvic panels. "Open up."
You took a deep invent. Well, here it was - the moment you bared your valve to your crushes. You reminded yourself it was for medical purposes, but a part of you thought it would've been less embarrassing if the scenario had been less, ah, professional.
You slid your panels back, and Breakdown gave a lopsided smile with a raised eyebrow. "Huh. I guess I can see why you prefer your valve, you got a real cute one."
"I... oh, um... that's..."
"Oh Breakdown, can't you see you're embarrassing them?" Knock Out teased. "Even though you are correct."
Oh, slag - all this attention was going to make your valve start lubricating, and they'd definitely notice that. Primus take me now.
Thankfully for your modesty, they stopped talking about your valve for a moment as Breakdown coated the catheter in some kind of gel before handing it off to Knock Out... only for Knock Out to sit on a stool right in front of your nether regions.
He put a hand on your thigh, which you thought oddly intimate for a medical procedure. Looking up at your face for a moment, he said "I'm going to insert it now, try to hold still."
His hand moved from your thigh to your valve, pulling the node upward to better expose your waste nozzle. The touch sent a rush of excitement through your frame, at least until he started inserting the catheter.
You tensed up in discomfort, a grunt escaping your vocalizer. Breakdown winced in sympathy and touched your forearm, the gesture surprisingly comforting. "Yeah, I bet that's no fun."
The catheter felt like it hit a particularly snug part of your waste pipe, and you couldn't help but tighten your pelvic area reflexively to keep the intrusion out. Knock Out put a hand back on your thigh and gently rubbed it. Where it would've been embarrassing before, you now found yourself appreciating the attentiveness during your discomfort. "Try to relax." He mumbled.
Finally the catheter went through, and the end felt as though it had breached something deep inside of you. It was a relief that it had finally stopped moving, until you felt a warmth in your waste pipe.
That... would be your waste fluid draining out. Your crushes were watching you void your waste tanks, and if dying of embarrassment were possible you'd be so dead right now even Knock Out couldn't save you. You hid your face behind your arm and actually groaned.
Knock Out patted your thigh. "You're doing great. After this we can get to the fun part."
That was... interesting. "The... fun part?"
Breakdown snickered as the waste bag finished filling up and Knock Out finally removed the catheter. You were immensely relieved to have that out of you, and noticed that your abdomen was no longer aching.
Knock Out gave you a knowing look. "First, a question. Purely one out of curiosity: How long have you been attracted to us?"
How did they know?!
Breakdown grinned and added "You stare and blush. A lot."
Oh. That's how they knew.
"... since I was first transferred here?"
Knock Out turned to Breakdown. "You owe me 20 shanix." He then looked back down at you, a mischievous glint in his optics. "All right, the next part can go one of two ways: We can leave you to self-service and empty your transfluid sac yourself, or - and I highly recommend the second option - you can let us help you by massaging the sac through your valve wall. It's very difficult to reach by yourself, but it feels fantastic, trust me."
With what he was implying with the last part, you got the mental image of Breakdown massaging the inside of Knock Out's valve. Holy hell, you'd never been this turned on in your life, and they could definitely tell from how they stared at your valve.
Breakdown chuckled. "I think we have our answer from how much they're lubricating." Their stares brought a thick glob of lubricant sliding from your valve, and your channel clenched in anticipation.
"Let's not get ahead of ourselves Breakdown, we need a verbal response." Knock Out said as he shot a smoldering look in your direction.
You were beyond being embarrassed at this point, too horny to care and too happy that your crushes were reciprocated. He wanted you to beg? You could do that.
"Please, just - just wreck me! I've wanted you both to split my valve open from the moment I saw you! Make me overload until I can't walk!"
"Oh, you are too cute." Knock Out responded. "Open up your spike panel and we'll get you all taken care of, sweetspark."
Your spike panel opened, revealing a half-chub that Knock Out immediately grabbed and started stroking. Breakdown stood between your thighs and started rubbing a digit against your slick, sensitive channel.
"Please -" you gasped out. "I, I need - inside."
"Oh, you're not ready to take one of Breakdown's digits yet, dear." Knock Out reached over to insert two of his digits into your valve as Breakdown wrapped a servo around your spike. The digits felt along the front wall of your valve until he felt a protrusion and pressed.
A lightning bolt of pleasure shot up your spinal strut and you arched off the medslab, moaning shamelessly. "Ah, there it is." commented Knock Out. "Feel that? That's your transfluid sac. Massaging it gives particularly powerful overloads."
He scissored his digits a few times before adding a third one, then massaged your sac again with firm but gentle strokes. Every touch to it sent an intense wave of pleasure through your frame, and had you panting and keening.
Breakdown moved his top two digits away from your spike, which was throbbing with need at this point. You could already see a dribble of transfluid coming out of the tip. "Look at that! Leakin' already."
Knock Out gave your sac one last loving stroke before withdrawing his digits. "Mmm, I think you're ready for him now."
Breakdown inserted a single digit and pressed hard. You swore you saw stars as you arched off the medslab again and shouted. Knock Out returned to giving attention to your spike as Breakdown pistoned your valve and massaged the inner wall. You were moaning and keening constantly now, surrendering to the onslaught of bliss coursing through your frame.
"It's too bad you don't use your spike much, you've got a nice one." Knock Out remarked. He popped the head in his intake and swirled his glossa around the tip, making you shiver. "You know, I really meant it when I said you're adorable. You're just so cute when you're flustered."
"O-oh, I... HNnnG!" You cried out as Breakdown hit a particularly sensitive spot. The squelching sound as he moved his digit inside of you was downright obscene.
Breakdown smiled up at you. "You're also cute when you moan, y'know that?"
A pressure was beginning to build in your lower abdomen. Unlike before, it was pleasant and electrifying. For a moment you imagined what his spike would feel like instead of his digit.
"Think you can handle another digit?" Breakdown asked.
"P-please, I need - AHHH!"
The stretch was incredible, your walls clenching down as your valve tried to wrench as much friction as possible. You were hot and throbbing and felt like bursting any moment now.
Knock Out reached over and started kneading your node as he rubbed your spike, rolling the sensitive little nub between his digits. Your entire body was shaking at this point. He deepthroated your spike, swallowing around the head to massage it. He looked up, giving you a heated, half-lidded expression.
Between the digits in your valve pressing into your transfluid sac, the digits rolling your node, and the intake on your spike, you realized you were on the verge of the biggest overload of your life.
"Frag... frag..." You could feel your entire frame tense up, the knot in your abdomen getting tighter and tighter. Your valve had a death grip on Breakdown's digits and your spike was rock-hard.
Knock Out popped his intake off your spike and resumed stroking. "I think our sweet little pet is about to finish. Breakdown, hand me the beaker, would you?"
Knock Out's digits left your node only to be replaced by Breakdown's. He rubbed in a rapid up-and-down stroking motion, and pressed into your transfluid sac hard and palpated.
"PRIMUS!!" The dam burst. The knot in your abdomen unwound, and you were cycling down on Breakdown's digits as jet after jet of transfluid pulsed into the beaker Knock Out was holding. You shook on the medslab, overload rocketing up your spinal strut as you keened in a high-pitched voice. Except it didn't end there - your overload bled into a second overload as the ministrations on your spike and valve continued, sending you into a silent scream as intense, mind-numbing ecstasy verged on pain. You heard Knock Out practically purr at you. "That's right, let it all out..."
Finally, after what seemed like an eternity, your spike stopped spurting and the digits withdrew. You collapsed onto the medslab, utterly strutless and spent, cooling fans on their highest setting. That had been the best overload of your life.
You looked up through hazy optics and saw Knock Out set the beaker on a tray, nearly filled to the top with silvery transfluid. Holy hell, all that had been inside me?!
He had a small splatter of stray transfluid on his face. Without breaking optic contact he picked up Breakdown's servo and licked your lubricant off his digits, and Breakdown wiped your transfluid off Knock Out's face and lapped it up. "Mmm, sweet. Just like you." If you'd been capable of overloading again that definitely would've done the trick.
Breakdown grabbed a cleaning cloth and gently wiped you down, careful to avoid overstimulating your array. Knock Out grabbed a canister and handed it to you. "Here, you're going to need this." It was coolant, which yes, you definitely needed. You drank it down gratefully and he took the empty canister back from you.
Knock Out set the berth back to its default position. "All done!" He said cheerily. "You can close your panels now."
"Th-thanks." You breathed out.
"Any time, my dear." You had a feeling he meant that literally. "But next time, don't neglect your health."
After closing up, you sat up on the medslab, swaying slightly. Breakdown gently supported your back. "Here, lemme help you." He let you hold his arm as you got off the berth, and you only let go when you were sure you could stand. You wobbled toward the exit like a newborn zaphorse.
"Oh, by the way..." Knock Out called out after you. "Our hab suite is to the left of the medbay. Feel free to drop by when your shift ends." He winked as Breakdown gave you a wide grin.
You nodded dumbly. Well, that was the best overload of my life so FAR.
