Starscream is going CAVE DIVING!!!

[transformers-spike]

Very horned up about the idea of reader obliterating Sentinel with some xenophilia themed dirty talk:

“Valve just isn’t tight enough for you anymore is it? Need something softer and hotter than metal…”

“My fist is so small, yet you’re drooling on it like I’m stretching you wide open…getting off on having a filthy organic all up inside you?”

“Wonder how cybertron would react to their sub commander whining for more human pussy? I can’t ever shave because you’d throw such a fit…”

Just. Ough. Bully him about his kink. Turn the tables on the whole “ruining you for other humans” and ruin him for pretty much every other cybertronian. Even with Optimus in their group nothing gets him wetter than being a little alien’s plaything…though maybe optimus’ spike in his aft is a close second.

YES YES YES THIS IS SO GOOD

I hope they call Sentinel a slut and squeeze his anterior node

This is exactly how I picture his relationship with a human. They're the one ultimately calling the shots and pushing him over the edge. If they lie down and let him take the reins, he just stares at their valve like he's formulating a strategy. Human pussy scares him

[mangommie]

They love each other very much <33

[yandereine]

I had the most terrific idea and urge to write a slave coding fic but I couldn't decide on continuity. There's so much to be done and I geneuinely don't want to start yet another 24k+ fic I don't complete because my interest waned.

But...

aw he's too cute not to put through a meat grinder

Slave Coding Brainrot Go!!

G1: This one tastes the sweetest. Because Bumblebee is just so kind and innocent. But he's always being picked on by larger bots and unlike Rumble doesn't have it in him to literally smash them through a wall. I love the idea that Prime would be logical about it, would remain calm to get him fixed, but I think it would wear on him. As most problems, even in the comics, were resolved within an episode/issue. When they weren't, OP tended to get testy. He was always about jokes and knowing he could handle it, until he couldn't. Then Orion started to come out. Bee himself would probably be miserable. Genuinely and utterly miserable. Because he sees his brothers in arms as close friends, he would hate to be seen bowing, begging, and a living foot stool. But I think he'd also be the most afraid of pain. The code would snap at his insides with electricity and heat, and the threat of agony would quickly keep him in line.

------------------------------------------------------------------------------

07: Would be the angriest by far. Bayverse Bumblebee is beyond proud, cocky, confident, and kind of a jerk. Beer pong frat boy with a volleyball player/otter mode type of body youthfulness. He's the shit, he knows he's the cutest (puppy dog act which Drift calls him out on) and is used to getting his way if he pouts. But that control's been taken. He's a slave. The pain would get to him but he'd be bubbling from the inside with how much he'd withstand. Serving Prime wouldn't bother him so much as it not being his choice. He would feel loads of embarrassment from how utterly weak he presents himself and knowing it's hurting him would probably even cull cat calls from Crosshairs or insults from Drift. The other bots, like Ironhide and his elders, would be working nonstop to try and find a way to help him because the idea that their youngest soldier is reduced to this would piss them off. It would be so, so unbecoming.

------------------------------------------------------------------------------

Knight/Rotb: By far the most helpless. The pain wouldn't bother him the least. He's survived so much and the trauma of emotional pain would harm his processor so much more. He'd be tortured by memories of, well, memory loss, actually dying, and would feel like an absolute failure while he's on his knees. It would probably break him if not fixed within a certain timeframe. As he'd feel his failures piling and piling enough to completely drown him. Autonomy is something he treasures and to not have it would wreck him inside.

------------------------------------------------------------------------------

Animated: The most indignant by far. He's been through enough humiliation but he'd be more upset by the shocks and burns from not going with the code when he actually wants to work with it. He's not exactly prideful of his looks, arrogant but not totally vain. He'd probably be flattered by any reciprocation he got servicing his master in a 'oh is that really how he feels?' way. Autobot society in Animated is so FUCKED the mere idea of slave coding would probably seem like a 'yeah, duh' thing to him. Ratchet knew how to lobotomize OP and he offered it like a baggie of weed. He wouldn't be horrified, more than anything, he'd be annoyed that they can't just cure him because he's bored, he wants to go out, and would roll with the code to wiggle his way into just lounging. But he'd likely stay far away from Sari as he'd care enough to not want her to see something she's not ready for. I think he would be more than glad if OP was holding his leash. Because he trusts him, and knows he would feel bad about using him. Not to say the others would- but his relationship with OP is so close. He'd trust his judgement and care.

------------------------------------------------------------------------------

Prime: Mind broken on first contact. Would refuse to see the kids. Would detest himself despite knowing it's not his own processor. Embarassed, uncomfortable, sick to his tanks with having everyone see him begging for his master. Since he cannot talk, it makes it even worse because he can't communicate with nuance or express himself to his fullest. Wouldn't be able to look Bulkhead or Arcee in the optic. Would probably retreat to Ratchet despite the code forcing him to remain with his master because Ratchet would actually nonstop work to fix him. But OP's gaze would probably make him vomit if he had the capability. He loves OP to literal death. Would die for him again and again. This not how he wants to be seen. And it would rip at his core to an endless depression. The code would likely be the closest to killing him because he'd fight and fight and fight and fight.

------------------------------------------------------------------------------

IDW: Would enjoy it the most. He's been put through it, and not once earned anyone's complete respect. He's been in positions where nothing he does is the right call. Having that control taken from him would be such a selfish relief. He no longer has to think, just accept he's owned and be glad he'll always have someone to take care of him. He'd be heartbroken it had to end like this, but even if he got cured, he'd probably miss the nonstop physical touch and love. So much of IDW is just Bumblebee going out on his own, fucking up, and having to suffer. None of that. He can just lie back and be adored by someone who wont ever leave him. The war took a toll on him the most, as seen by his anger issues close to Dark Cybertron and how happy he was having Starscream with him for eternity. That bot was mind broken and just accepted he was never winning shit.

------------------------------------------------------------------------------

RiD: Rolling with it. Would still try to do his job but knows he's going to have to sit through it. He wants to help his team, and stay in control, but he's by far one of more logical iterations. The actual slave coding episode (wew I can't believe I can actually say that.) shows that they for the most part do not have an override. Sucks, but they gotta endure. If he can think for himself in any capacity he'd just rather be fixed while putting out enough for the code to leave him be. It'd be exasperating, but RiD Bee cannot fathom embarrassment anymore. He's too tired.

------------------------------------------------------------------------------

Rescue Bots: The most logical and most willing to stay in a room with his master and let it work itself out. He'd have enough sense to keep the kids out of it. Wouldn't talk to Cody, wouldn't let Wedge near him. He understands what it's like to look up to someone besides literal looking up, and would keep things quiet with Doc Green and Ratchet or Perceptor. It wouldn't be a problem so much as an understanding he'd have a lot of apologizing to do.

------------------------------------------------------------------------------

One: Crippling lonliness but he has incredible survival instinct. He'd want to learn the rules, may get zapped, but he is exceedingly subservient to preserve himself. He wouldn't like it, but he knows how to keep quiet when he's in actual danger. The meeting with the high guard isn't a situation to be afraid of, as he knew them as protectors. They weren't bad, they were just gone. It was like meeting a crew of his heroes vs Sentinel and how he told D-16 to stay down. He would. He'd sit, and stay, and kneel, and do everything to survive. It wouldn't hurt him outside of a misunderstanding of orders or conflicting orders. OP owning him would be a relief because he likes OP a lot. He's only been around him for a short time and knows he's in good hands. He'd mostly be upset that he has to do things the code's way not his way.

------------------------------------------------------------------------------

Earthspark: He is not happy. He finally can get some adult attention and spend time with bots his age, and he's got to be demure and not tell jokes or just chat. He wanted to get away from the Terrans and raising kids that were not his so badly and now he's got to spend his days in silence, doing what his master wants. And Optimus, if given the controls, would not be a good one. Nobody would. Megatron would be too uncomfortable and end up hurting him. Elita would accidentally get him severely injured by trying not to mess with the code and have him feeling neglected. Arcee might actually kill him with her misplaced good will. But Optimus I feel would use the code in private in a way that makes Bee feel sick inside. ES OP is fake. Fake smiles, fake care and is fine using people. He doesn't view the cons as equals and agrees to their horrendous mistreatment. He'd keep Bee in a room, fill the requirements for the next day, and leave him there. OP could leave feeling serviced and relaxed and Bumblebee would be missing his itchy barn bed with all the aching in his spark. Even if he was allowed to stay by OP's side, there would be such a lack of emotional support that he'd contemplate walking into the ocean and just staying there until he rusted horn to metal toe.

------------------------------------------------------------------------------

WFC Trilogy: What slave coding, he is going with it all in. He met Alpha Trion for literally less than 3 seconds and was willing to stay by OP like his autonomy didn't matter. There are no problems, he's just going to stay in his master's lap and as long as he doesn't need to bow it'd be as natural as transforming.

------------------------------------------------------------------------------

WFC Game: There are no downsides besides being unable to negotiate. He would not be all in, but he'd be willing to endure if he could set terms.

------------------------------------------------------------------------------

Cyberworld: Energon is Energon. He'd get shocked internally a lot but as long as he's taken care of, he can deal. He wants OP to look at him, to keep him close, and to do things that benefit them both. As long as they can keep winning Energon together then he will be ok. He was happy getting praises from Megatron, the idea of being doted on would just be another bonus. Elita might keep her distance but she'd likely accept it and help him. She's seen messed up types of games and what bots can do to each other while figuring out how their loss of autonomy works. It's fine.

Breakdown/Knock Out oneshot - Written by Renard [🪚]

Knock Out tries something new with his beloved Conjunx.

Rating: Explicit

Cross-posted from AO3 - Read it here!

After a long day of working their afts all day in the med-bay, Breakdown and Knock Out finally settled down in their habsuite and got their well needed rest, but the medic had other ideas. As the bigger mech laid on his back beside him, Knock Out nudged him to catch his attention, waking up Breakdown in the process.

"Say, sweetspark, how about we try something new tonight?" Knock Out asked, smirking at his Conjunx, there was a twinge of sultriness in his velvety voice.

"Of course, darlin'. I'm always up for somethin' new!" The blue bruiser exclaimed, the thought of trying something new with the mech he truly loved never ceases to get him all giddy. He's always open to experiment with his Conjunx, medical or otherwise.

Knock Out crawled on top of the larger mech and straddled him, bringing his faceplate closer to his and enveloping him in a passionate kiss. Breakdown opened his intake, inviting his Conjunx's glossa in. The medic pushed his helm further, deepening the kiss as their glossas wriggled for dominance and lubricant pooled to their chins. Both of their servos ran along their frames and grinded against one another as their kiss becomes more lustful. Grunts and moans slipped out from their intakes as they enjoyed each other.

Knock Out eventually pulled away from the other's lips, leaving a trail of saliva behind as it separated.

"Can ya open up for me, KO?" Breakdown asked as he brushed a digit on the medic's interface panel, causing him to let out a soft whine.

"You first, big boy." The sultriness in the medic's voice aroused Breakdown, causing him to make quick work of his interface panel. His huge, thick spike quickly pressurized as Knock Out looked in awe at his length. No matter how many times he's seen it, the sheer size of his lover's spike always delighted him to no end.

Knock Out soon followed, his spike wasn't as thick as Breakdown's, but he was pretty well-endowed for a mech his size. He gently rubbed his length against the other's as pre-fluid beaded at their tips, one of his servos joined in shortly after and pumped both of their spikes, adding extra friction. They both let out pleasured moans and grunts as they rutted their spikes against the doctor's hand until both of their overloads combined with one another.

Despite his larger stature, Breakdown already looked drained after overloading in their first session. Knock Out went down and cleaned the both of them up by licking their excess fluids. Seeing his Conjunx lap up the result of their sweet lovemaking aroused him all over again, bringing the bruiser back from exhaustion.

"We still have a loooong way to go, sweetspark." The medic snarled, trailing his servos onto his aft plating, gently rubbing it as Breakdown whimpered and whined at his touch.

"Please, doctor. Let me have this!" Breakdown whined in desperation, expecting the smaller mech to use his valve. He ruts against the other's servo as Knock Out ran his digits along the larger mech's seams.

"Now, sweetspark, I want you to bend over and show me your juicy little port." Breakdown obediently followed his command, rolling over and presenting his aft in no time, revealing his tight pucker to Knock Out as his impressive spike hung between his struts. Knock Out bit his lip at the sight, trying his best to restrain himself from fragging him silly so quickly.

"Be gentle, darlin'. I haven't done anything like this before." As open as he was to trying something new, he always takes precautions beforehand.

Knock Out gave his Conjunx a reassuring look before running his glossa over the hole, tenderly caressing his aft-hole as Breakdown's frame shudders in arousal. He couldn't believe that after vorns of them together, he never considered feeling this kind of pleasure. his spike was throbbing and twitching, desperate for attention as it leaked copious amounts of pre-fluid.

"Primus, I never expected how good you'd taste." The medic was completely lost in bliss, the taste of his own lover on his glossa drove him mad as his own spike twitched and throbbed. Coarse moans and delightful whimpers escaped the larger mech's intake as Knock Out crammed his glossa deeper into the passage, he was growing closer to his overload.

Sensing how close he was getting, Knock Out swiftly pulled away from his pucker. The brute grunted in disappointment as the smaller mech denied him of his release.

"I'll give you something better instead, dear." The smaller mech grabbed a half-empty bottle of lubricant from one of the drawers, Coating his digits and Breakdown's port with a generous amount of the liquid.

He prepares the larger mech's tailpipe by inserting two of his digits inside, making sure that it'd comfortably fit his spike. The foreign sensation of being penetrated from something other than his valve caught him by surprise, but he got used to it fairly quickly. Breakdown let out small groans and moans as Knock Out went to town using his digits before shortly pulling out when he considered it to be loose enough for him.

"Go ahead, darlin'. What are you waitin' for?" Breakdown said eagerly. The smaller mech's spike slapped against the wet pucker before he slowly inserted the head of his length into the tight passage.

"By the Allspark! You're tight as slag, Breakdown." Knock Out moaned as his spike wriggled deeper into the brute's aft-hole.

"I told ya it's my first time doin' this." The larger mech reminded. After they both finally adjusted to the new sensation, the medic slowly started moving, making sure that the other is comfortable. His spike was reaching depths that he never considered exploring.

"Unngh– Knock Out! You feel so fraggin' good…" Breakdown grunted, his engines revved as the smaller mech thrusted harder, squeezing out moans from his Conjunx. His optics twitched as his glossa hung out from his intake.

The medic repeatedly slapped his aft as he went at a rapid pace, the head of his spike continuously hitting the most luscious spots of his hole. The room was nothing more but a menagerie of rough clanking noises and passionate sounds of their lovemaking, it smelt of nothing but sweet, hot motor oil and their excess fluids. Breakdown was completely at Knock Out's mercy, letting the other absolutely demolish his then unused aft-hole.

"Mmmh– Oh, Frag, Breakdown. I'm so close!" Knock Out reached a servo to the other's length and swiftly jerked him as he continued his rough pounding, timing it with his thrusts. Both of their circuits went haywire as they lost themselves in their own pleasure, shaking and trembling as they get closer to their climax.

Finally, after a rough session, they finally came to their releases as thick globs of transfluid spurted from their spikes, staining the sheets with their combined fluids. The then white sheets were now tinted with pink as a result of their passionate love. Knock Out hastily pulled out from his Conjunx's tailpipe before admiring his stuffed, gaping hole. He kissed and licked at the used tailpipe, slurping up his own fluids as he marveled at his own work. The smaller bot eventually pulled off from the pucker, leaving a string of saliva behind as it made a 'schlk!' sound. Knock Out laid Breakdown on his back as he shoved his glossa into the other's intake, giving the bruiser the taste of his efforts before slowly pulling away.

"You cleanin' this up, Doc?" Breakdown teased, already knowing the answer. Knock Out let out a playful sigh as he quickly got to work changing the sheets to brand-new, fresh ones before grabbing some cubes of Energon. Breakdown yawned as he pulled Knock Out close to him, holding him in a warm embrace after they both refreshed their systems. The smaller mech melted into the cuddle, nuzzling his helm onto the other's chestplate.

"I love you more than ever, dear. Perhaps we should do this again some time soon?" Knock Out offered, giving his Conjunx an endearing gaze.

"It's always a pleasure trying new things with you, doc." Breakdown mumbled before he kissed the top of his helm as they both fell into recharge.

[valveplugconfessions]

we need more spike in aft works. im being serious. especially t4t yuri stuff because like i have yet to see anyone make valveplug (or aftplug in this case) where a femme shoves her spike in another femme's afthole and turns her prostate (idk the cybertronian equivalent) into dust. we also need more lesbian frotting too. aftplug yaoi is cool too but i have never ever seen aftplug yuri. t4t yuri in this matter. sorry if this sounds too chaser-ish i just think girlcock is hot but not in a creepy way
