"Oh! That's What That Does?!"

G1 Rumble/ Mechanic Reader - 2400+ Words NSFW, Valveplug, Plug 'N Play, Mild Sparkplay, Accidental Stimulation, Edging, Human Reader, GN Pronouns

Ahh, the inherent eroticism of repairing your machine.~ I've had this one cooking for a while, so I hope you all enjoy! I've also gotten pretty attached to this mechanic Reader, so they'll likely pop up again with other cassettes (and maybe even some other Decepticons!)

NSFW WRITING AND IMAGERY BELOW THE CUT!

“Ey… EY! Careful wit’ dat! It’s touchy!”

“Rumble,” You groaned, pinching the bridge of your nose. “You're making this way more difficult than it needs to be.”

“I wouldn't be complainin’ if you'd stop touchin’ all up on bits that don't gotta be touched! Rootin’ around in there like I'm one’a your crappy organic machines!”

Removing your hands from Rumble’s open chest, you tossed them roughly into the air. “Y'know what? Fine. Do it yourself. Better yet, get Frenzy to pull the shrapnel out of your chest. That'll go great.”

You would have slid off of Rumble’s lap and stormed off, if not for his massive servos closing around your wrists with an unexpected delicacy. Your efforts to remove your hands only reinforced his grip, using just enough force to keep you from leaving without crushing your wrists entirely.

“H-Hey, no need ta be so hasty! Look, I’m just steamed cause'a the battle, dat’s all. Frenz’ can't do dis, it's gotta be someone more… dainty. Y’know. Little human hands and all dat.” The harsh glow of his visor had dulled slightly as his gaze cast down to your hands. You rolled your eyes, wrists finally slipping from his grip as you settled back in. 

Dangling wires and sparking shrapnel dotted his open chest cavity, illuminated by the light of his spark chamber. Rumble had staggered off-balance into your workshop whining about the prodding pieces of broken metal keeping him from transforming properly, yet you’d barely managed to get two wires back in place before he started squirming and whingeing and slinging verbal abuse at you.

 Not that you weren't used to it, any interactions with Rumble and Frenzy usually involved some level of bullying. Fortunately, the two cassettes are also incredibly predictable. As soon as you would threaten to take away or withhold what they're asking for, they’d start falling all over themselves with apologies and placations. After all, you may not have been the only mechanic in the area, but you were certainly their favorite.

“Are you going to actually let me work? Or are you going to start yelling at me again?”

“Yellin’? Who's yellin’? Yer the mechanic here, my spark is in your squishy little hands. Do your magic, doc.” He sat back again, servos clutching the edges of your workbench in a show of effort, a genuine attempt to keep them still (or however genuine any show of rule-following from Rumble could be.)

“That's what I thought. Now let me actually fix a few things before you start whining again.” Your gloved hands dipped back into his chest cavity, skirting the edges of his spark chamber to pick away at the bits of loose shrapnel stuck in some of the wires. His frame shuddered, a hiss of steam escaping through his dentae as your knuckles brushed the underside of the spark casing.

“C-Careful,” He said again, with significantly less bite to his tone.

“Does it hurt?”

“Somethin’ like dat.”

“I'll be careful, so let me know if it gets to be too much.” You smoothed a palm down the armor covering his stomach, flinching back when you heard another sharp hiss of steam.

“I’m fine! It's fine! Just… do ya gotta be all on top’a me like dis?”

“I can't reach properly if you're laying down. If you're standing you might keel over on me, and I really don't feel like being squished to death today.” He let out a low grumble as you jacked another cable back into its proper port. “I'll try to be quick, that way you won't have to worry about my ‘human germs’ and you can get outta here. Deal?”

“Yeah, yeah. Just-”

“Be careful. I know.”

And with that you went to work, separating and organizing cables, taping off leaky tubing and removing pieces of scrap metal as gently as you could. Every once in a while Rumble would jerk or twitch beneath your touch, letting out a muffled curse or huff but sparing you from his usual complaints. It was… uncharacteristically quiet, for sure. This was the most extensive repair you'd ever done on him, though, so maybe he was just having surgery jitters.

“Okay, I've gotten most of the shrapnel out. But there's a piece right behind your spark casing.”

“Well? Get it outta there!”

“I'm going to, but I need to get my whole hand in there. I'm warning you now because it's going to be bumping up against your spark casing a lot. I'm going to do my best but you have to tell me if it hurts too much.”

Rumble let out a long, pathetic groan. “Actually doc, maybe you can just leave dat one in there? F-For funsies?”

“Eh?! Rumble, I’m not gonna just ‘leave it in there’! It's gotta come out.”

“Something's gonna come out if you keep proddin’ around in there like dat…”

“What was that?”

“Gh! Nothin’! Don't worry ‘bout it!”

“...Okay. I’m gonna start now. Are you ready?” Rumble only responded with gritted dentae and a tense nod. Working your gloved hand under his spark chamber, you could feel the ambient energy making the hairs on your arm stand on end as you felt for the jagged edge of broken metal. Your glove blocked your view entirely, so you were left blindly groping your way up the metal surface, feeling for anything bent or out of place. When your fingers could no longer reach any further while still avoiding the casing, you slid forward and ducked slightly into Rumble’s open chest, the back of your hand pressing up against the underside of his spark chamber.

CLANG!

You jumped, and if it weren't for Rumble’s arm wrapping around you and almost crushing you into his open chest you may have jostled the sensitive chamber even further. You slid your hand back again, easing off of the reinforced glass, and his grip receded.

“What the hell was that? And what was that clang?”

“I said don't worry ‘bout it!” He hissed, voice glitchy with static. “Everythin’s totally normal, I dunno why you're getting all jumpy ‘bout- MMNGH?!” You moved your hand up again into the same position, and Rumble let out an embarrassingly high whimper. You glanced up at his face, a flush of pink behind the usual grey and beading with coolant… and something clicked.

“Oh my God are you getting off on this?”

“N-No!”

Behind you you heard a sharp snikt, and the sound of pressurizing hydraulics.

“...Maybe?”

“Jesus fucking Christ.”

“H-Hey, don't go gettin’ a big head or nothin’! A bot’s spark chamber is sensitive! Don't go thinkin’ this is cause of your squishy frame or your soft little digits or nothin’!” He seemed to almost shrink in on himself, face plate practically glowing as his shoulders pulled up around his helm. You'd never say it to his face, but he looked surprisingly… small, at this moment. You heaved an exhausted sigh.

“Okay. Okay. I'm going to get this last piece out, alright? It's the last one. And whatever happens while I'm doing that..? It just happens. We won't bring it up again, no need to be embarrassed. Deal?”

“‘Deal?!?’” He squawked, positively scandalized. “How do I know yer not gonna gossip with Frenz’ the next time he's in for a tune-up?”

“Well Frenzy usually never lets me get a word in edgewise, first of all.” You huffed. This was way more than you'd signed up for. “I'm not going to make fun of you, Rumble. Let’s just get you patched up, then you can head home. Okay?”

His mouth was pulled into a tight, wobbly frown as he glanced down at you, choking out a single word. “...Promise?”

“I promise.”

“...Slag. alright, let's get dis over with.” He lolled his head back against the table with a clank, resigning himself to his fate. This time, when your knuckles brushed his spark casing, he couldn’t stifle his soft moan. Your fingers felt further and further up, until almost your entire hand was behind the glass bubble containing his pulsing spark. Finally, you could feel the jagged piece of metal. You wrapped your fingers around it and gave it an experimental tug. It stuck fast, and your hand bumping against Rumble's spark only pulled another surprised moan from him.

“W-Watch it!” He yelped, sounding too fucked-out to come across as actually threatening.

“It's really stuck in there. I'm going to start working it out, so let me know if you need me to stop.”

“Wh… workin’ it out? Whadda ya- ohhh…~” 

With your thumb and forefinger gripping the edge of the broken metal, you began to wiggle it gently back and forth to ease it from the plating and wires around it. Each time you moved the back of your hand rubbed up against the far side of his spark chamber, warmth radiating through your glove as Rumble started to vent more harshly.

“Slag… slag! Don't think it's ever been touched back there before. Feels… feels crazy.” He moaned. The metal of your work table shrieked and crumpled like cardboard under his iron grip, desperate to keep his servos off of himself or, Primus forbid, you. The piece stuck firm, and as you braced your other hand against the outside paneling of his chest to readjust your balance he let out a sharp, staticky yelp. “S-STOP!”

You froze immediately. “Are you okay? What's wrong?”

A few shuddering vents were your only response for a moment, Rumble’s visor lights flickering frantically as he tried to steady himself. “Whooo… Almost blew my top for a second there.”

“Seriously?”

“Hey! Yer the one that told me to tell ya if I need ya to stop! I'll be slagged to the Pit before I let some ‘squishy’ run my charge like dat.”

“...Can I start again? I’m making some progress here.”

“...Y-Yeah. Yeah. Yer good.”

You let out another soft sigh, trying to focus on the rhythmic sktch sktch sktch of metal on metal rather than Rumble’s shivering whines. His vocalizer pitched and warbled with static, attempts to stifle his own words slowly giving way to a deluge of fucked-out babbles.

“Ah! Gh! Ohh, mmnh, stupid little hands feelin’ all- nnh!~ Jus’ get it outta there! Please?”

I’m working on it. You’re doing good, just hang in there.” Your placations only resulted in another desperate moan. After what couldn’t have been more than another thirty seconds or so, he blurted out again.

“Ah! Stop!”

You retracted your hand for a moment, letting Rumble gasp for breath above you in a futile attempt to cool his core. You rubbed at his chest paneling as he shivered beneath you hard enough that you thought bolts were going to start coming undone. Even the paneling you were seated upon was burning up, heat seeping through the fabric of your coveralls. His glowing face plate was slick with coolant. Without thinking, you reached up and swept away a bead of it with your thumb, making him jump.

“H-Hey, quit dat…” He groaned, all bite lost from his tone.

“Rumble… The more you keep stopping me the longer this is going to take.”

“You think I don’t know dat?!” One of his arms draped dramatically over his face. “I’m tryin’! But you just keep pokin’ around in there and it’s all touchy and it’s makin’ me feel like my spike’s gonna burst and I can’t take it anymore!” He sniffled. Could Cybertronians even sniffle? You weren’t sure, but he sounded close to tears.

“Rumble… Have you ever actually edged yourself before?”

“Whu- Whuh? How’s dat any of yer business?”

“I’m just thinking…” You ran a placating hand down his shivering plating. “If you haven’t it can be really overwhelming, and-”

“I can handle it! I-I can!”

“Let me finish. It can be really overwhelming, and I don’t want you to hurt yourself further. Just… take a deep breath for me, okay?” You took a slow, steadying breath, and after a second he mimicked it. “Good. Just think about letting go, okay? I’m not going to judge you. Just think about it.”

He let out a low, pitying grumble, peeking at you from behind his arm plating. “...You can start again.”

Once again, your hands dipped into his chest cavity. Only this time you slid both hands up behind his spark casing, gripping as much of the broken metal as you could reach. As you rocked it back and forth Rumble’s moans returned with a fervor, one servo finally flying to cup your lower back.

“Ah! Ah! Slag, oh slag please! Please don’t stop I’m so fraggin’ close.” He fisted the back of your uniform, crumpling the cheap fabric between his digits. “C’mon, c’mon c’mon c’mon I need it!”

“Shh, I’ve got you baby. Just let it happen.”

With a metallic shriek and a gush of brackish oil the shrapnel popped free, the force enough to send you sprawling if not for Rumble’s servo in the small of your back. Of course, said unexpected force also slammed the backs of both your hands right into the underside of his spark chamber, and Rumble’s voice box screeched into a wail of radio static. Something hot and sticky splattered up the back of your coveralls; said something you decidedly were not going to look at until later. His frame rattled and shivered beneath you, steam venting and joints glitching and spark pulsating a near-blinding glow.  Finally, after a burst of noise and sparks and twitching, he went slack beneath you, helm clanking against the workbench as his optics flickered.

As delicately as you could, you removed the oil-slick shrapnel and let it clatter onto the floor before shedding your gloves and dabbing at his face plate with the cuff of your sleeve. With the whir of an old monitor blipping back to life, his visor blinked back up to its standard brightness.

“Whuh… Wheh?” He garbled.

“How you feeling, hun?”

“Like I got struck by lightnin’... but in like a nasty way.”

You choked back a snort. “Well, I’ve got all the worst of it over with. Feel free to rest for a while if you need it. I’m gonna go change my jumpsuit.” 

He let you slide off his lap without a fight, not even commenting until you’d turned around to make your way over to your office. Only then did he let out a low, salacious whistle when he’d finally caught sight of the back of your uniform.

“Comm me next time yer free, doc. Then I can repay da favor.”

[sideplug]

Yay or nay,

A human some how managing to find themselves trapped in a mechs modesty plating while they’re in a meeting, and can’t help but squirm and struggle to get free from behind the plating but the mech won’t let them out.

*SLAMS THE FUCKING DESK*

YES.

THIS IS ONE OF MY TOPPPPPPP FUCKING FANTASIES. You guys are like psychics how do you see into my brain like this. And man MAAANNN there’s so many ways this could go. Under the cut since I don’t wanna blast y’all in the face with paragraphs of porn BAHAHAA

One way is the “oh no this is sort of an awkward position for us both” scenario. The mech would get in trouble if he got caught with a human in such a position, and neither of them like it, but it was the faster thing they could think of in order to hide them. He just tries to stay as still as possible, trying to make sure you’re at least somewhat comfortable in this unfortunate situation. And you try and stay still too— as he could feel every little twitch of your body against him, and with such gentle touches on his spike… he can’t help himself as his spike starts rising to attention.

Two. The mech absolutely loves the power he’s holding over you right now. He feels your little body pressed up against his spike, struggling as he’s trapped you in such an intimate part of himself. It wouldn’t be such a big deal, right? You could chill there till the meeting was over. Though he knows that’s obviously not the case, based on your ceaseless squirming. But that was his whole, he knew you wouldn’t rub up on him otherwise if you don’t have a reason to. Your little hands thrashing on him until he shifts his legs, moving his spike in such a way that pins you entirely between his panel and spike. All you can do is uselessly wriggle around, a buzzing feeling that makes the mech have to choke down a moan in front of his companions at the meeting. His spike pressurizes in its casing, leaving you with even less room to breathe, and your eyes widen at the sight above you— an oncoming bead of pre-fluid building and daring to slip its way atop you. And even higher, blocked by the panel that covers you, the mech can’t help but bite his derma in anticipation, even more excited at just the thought of you covered in his transfluid.

Three. Y’all know me I’m a sucker for unaware. By some wild chain of events you end up in the mech’s panel with him none the wiser— maybe he was a mech too big to notice you. But the mech sits down for his meeting suddenly and without warning, already pressing you between the wall of his panel and his spike. He’s a little confused as his systems tell him of a feeling down in that area— but, as far as he was aware, nothing was down there to be felt. No matter how many times he internally resets his systems, the sensation never goes away. The meeting is about to begin so he can’t spend anymore time worrying about it, so he just dismisses it as a glitch in his nervecircuitry he’d just have to check out later. Meanwhile, inside his panel, you try desperately to get the big mech’s attention, but he pays no mind to you. Thinking nothing’s wrong, the mech casually crosses his legs, and you’re utterly squished between his legs, spike, and paneling. You are completely trapped, tiny body subject to his unaware whims— and with how he didn’t notice you, who knows how long you’d be stuck there…

[sideplug]

welcome to the club my friend, we have tits

Okay I think I might be fully into the idea of wanting to fuck a cybertronian I can't stop thinking about it like I'm sorry but having a giant alien robot slut me out in every way possible especially since they have such advanced technology there's a lot of kinky stuff you can do with them and

am i an alien fucker?

[sideplug]

yeehaw

[sideplug]

nice

(wouldn't say the attraction one is accurate, but this is nice either way)

[sideplug]

I absolutely get it, my periods stop me from walking sometimes, in all honesty 😵‍💫real nasty punishment for existing, aren't they?

frag yeah though! love a guy who's down to support someone & doesn't view menstruation as an ew yucky sinful thing. my personal favorite thing to imagine is having Cybertronians get eaten out on their periods... make that man SQUIRM. Or one of 'em slowly fragging their partner through it, not caring that much about the mess, just going on with it. Maybe even enjoying the mess.

Wild/rider would eat someone out on their period… god I know he’d be all up in that thing- tbh he’d probably prefer it a lil bloody

[sideplug]

I like to pretend that specific version of Prowl doesn't exist

@sideplug here, on anon for sideblog reasons.

just gotta say, I am absolutely in LOVE with your Prowl art. am I the only one who wants to see that man get eaten out? I want that twink obliterated 🫵

hi sideplug, thank you so much! 🥰❤️ im glad people seem to like it, seeing as its pretty much the only thing im drawing lately lol.

wait, twink..?

[sideplug]

no holy shit you've got a point

cmere buddy I'm into that shit

Wild/rider would eat someone out on their period… god I know he’d be all up in that thing- tbh he’d probably prefer it a lil bloody

[sideplug]

yo

openin a couple requests slots. nothing big, just a sketch of your favorite characters going at it

I am bored as hell and h✪rny as hell

to request: - post a comment - include the character(s) you want me to draw (I will do no more than two, maybe three) - include any poses, themes, general ideas, or k&nks you want me to add - bonus - please include a link to a ref or something if this is a more obscure character. I'm more than happy to draw OCs, I just need a reference.

this is for the first five people only, so do not comment if five people have already commented. also, there isn't any real guarantee that you'll 100% get your sketch done, as with all free things. but hey, I'll give it a shot.

TFP/bayverse characters are strictly off-limits for me, I refuse to draw the IDW character Rung, and I likewise refuse to draw anything abusive, proshippy, et cetera. I won't draw anything involving gore or scat (no matter how mild) or hard/medical drug use, especially needles. besides that, literally anything goes. I am into everything. test me.

[sideplug]

I didn't have enough of drawing this guy apparently, so I did a little sketch animation lol

Enjoy

“…in dreams” G1 Skyfire/Starscream inks

After going through @warlordenfilade‘s doujinshi when we were visiting, I got inspired to draw my very first OTP, something that I was surprised I’ve never done in the three-plus decades I’ve been in the fandom.

Will be finishing this in watercolour.

I felt like doing something more mild for once

I call it "Aero Guy films a porno" LOL

[sideplug]

Okay… so… uhm

How do we feel about robot tummies, folks? Maybe like… lil bit of love handles on a mech?

I’m in dire need of soft…
