Chapter Text

Jessie wiped her hands on her coveralls as she made her way down the dimly lit corridors of the spaceport, the stale air hanging heavy in her lungs. She had hoped a drink would calm her nerves after a long day, but as she moved through the thinning crowd, she realized something was wrong. The usual bustle of traders and travelers had slowed to a trickle, people pulling back, giving wide berth to a looming figure up ahead.

It was always tense, being so close to contested planets, where the Autobots and Decepticons seemed to constantly clash in the shadows. Though the Autobots were a peaceful presence on her ship, it didn’t mean she wasn’t aware of what their enemies were capable of.

That was when she felt it— in her feet at first, but as it got closer the vibrations of his steps shook the floor in a way that crept up further in her legs with each step. The crowd in front of her parted, like a wave pulling away from the shore. People were moving aside, giving wide berth to something, or rather, someone.

At first, she thought it might be a massive cargo hauler, some bot ferrying goods in their alt-mode. But then she saw it. The unmistakable frame of a Phase Sixer. Towering, silver and blue armor gleaming under the flickering lights, a malicious grin on his face. Overlord.

Her heart slammed in her chest.

Back, years ago now, when she had first been briefed about potential Decepticon encounters, there was a moment when the chipper Autobot presenting slides to the entire maintenance crew had to stop one of her coworkers from laughing. The whole talk had been pretty jovial. As far as Autobots went, Roll Stop had been very laid back even when talking about protocol for engaging with cons. Honestly, Jessie had thought the slide was some kind of weird joke too, all that was on it was the thumbnail for a video file. Blue con with big pouty lips that looked more like he was mogging for insta than about to commit quadruple digit warcrimes. But… when Roll Stop hit play, everyone shut the fuck up pretty fucking quick. Even the people in the shop who weren’t a part of the training stopped working to look at the projector screen.

That was honestly part of why this was a surprise. She saw him before her mind had time to catch up—tall, white and blue armor gleaming in the flickering lights, broad shoulders cutting through the space around him like a blade through air. He was too big, too menacing. Fuck.

All the next slide had said after Roll Stop eventually stopped the vid was “Evacuate organic personnel IMMEDIATELY, report exact location to high command ASAP”

Her heart skipped a beat. Every instinct screamed at her to run, to blend into the crowd, but her legs refused to move. There was no escaping someone like him. He was Phase Sixer. “Death incarnate came with the job title” according to Roll Stop. She had heard stories, seen the aftermaths, caught snippets of famous footage, but this close, it was surreal.

She lowered her head, quickening her pace, eyes fixed on the ground. Maybe, just maybe, he wouldn’t notice her. Just another human, another speck of life scurrying through the spaceport.

But she felt the weight of his gaze before his voice hit her, low and mocking, dripping with cruel amusement.

“Going somewhere?”

Jessie’s heart seized in her chest. She slowed, every muscle tensing, but she didn’t stop, didn’t make eye contact. Keep walking. Keep moving. She told herself, trying to ignore the rising panic.

It was no use. In an instant, a massive hand slammed into the ground in front of her, the impact rattling her teeth. She stumbled back, almost losing her balance, her eyes wide as they darted to the enormous fingers blocking her path. The sharp edge of his grin loomed above her.

“Look at you, trying to scurry off like a rat,” Overlord said, his voice thick with dark amusement. “What’s the rush, human?”

Jessie’s breath caught in her throat. She forced herself to look up, meeting his gaze for a brief, trembling moment. His eyes gleamed with predatory hunger, as if he had already decided what he was going to do to her. 

She took a step back, instinctively reaching for the knife on her belt—a laughable defense against someone like him. “I—I don’t want any trouble,” she stammered, her voice barely above a whisper. She didn’t need this tonight. No one needed this ever but she really didn’t need this tonight. Fuck.

“Trouble?” Overlord chuckled, the sound rumbling deep from his chest. “Oh, I think you’re already in trouble, little human.” He lowered himself, bringing his massive frame closer to her, towering over her even more as his face loomed mere feet from her own. “Do you know who I am?”

Her mouth was dry. “Overlord,” she forced out, the name flashing the image of it written out in all caps red text on a slideshow in her head.

He grinned wider, pleased. “Good. That saves me the trouble of explaining.” His optics flared with cruel excitement, like a predator savoring time spent playing with its prey. “Though I doubt you truly understand what that means for you.”

Jessie’s heart pounded in her chest, but her brain was being a cunt. She could feel the rising panic clawing at her throat, the sense of inevitable doom tightening around her like a vice. Freeze response really had her drifting in and out of her body this time. A giant, unstoppable… *fuckboy*…. was here and monologuing at her. This couldn’t be real.

“Look, it’s late, I won’t tell anyone I saw you if you just let me go.” Maybe he’s normal, she had met cons before who knew how to turn off the whole every moment is a part of the ongoing cartoony ass space war part of their brain on shore leave. They may be a part of an entire race of aliens who spent so much time at war that warped their perspective on what *rest* actually means, but they’re not all fucking on the clock 24/7.

“Let you go?” Overlord tilted his head, as if considering her words, but the grin never left his face. “Oh no, little human. You’ve caught my attention, and I’m going to make good use of you.… I’ll make sure every last drop of you is put to excellent use.”

Jessie’s stomach twisted with dread. She took another step back, but his hand moved faster, snatching her up with terrifying ease. His fingers wrapped around her body, cold metal pressing into her sides, lifting her off the ground like she weighed nothing at all. She gasped, kicking instinctively, but his grip was unrelenting.

Jessie’s pulse spiked as she writhed in his grip, her eyes darting wildly around for any possible escape, any sliver of hope. There was nothing. No one. The spaceport’s thinning crowd had all but vanished, leaving her alone with the towering monster who seemed to revel in her helplessness.

Overlord tilted his head back slightly, savoring her desperation. “You know, there’s a market for this sort of thing. Bots and fleshbags with strange tastes… they pay a lot to see something like this. To see someone like you squirm and scream before you’re turned into fuel.” His grin widened, showing off his obscenely handsome canine teeth. “And I enjoy giving them what they want.” Overlord looked somewhere past her and adjusted the angle he was holding her at… the corner of his lips curling up even more when his eyes met something in the distance and dilated.

Jessie’s stomach turned as her body trembled in his grip. This wasn’t just some cruel joke, it wasn’t exactly reality though either…. He meant it though. He wanted this. But he wasn’t just focused on her, something else was going on too.

“Let me go!” she yelled, her voice hoarse with panic, thrashing harder, her two inch blade folding knife slashing uselessly at his metal fingers. “I’m not—You can’t do this!”

Overlord chuckled, clearly enjoying her desperation. “Oh, I can. And I will.” The words were delivered with practice.

His optics flared with excitement as he shifted his grip, bringing her closer to his face, letting her see the full scope of what was coming. He opened his mouth slowly, the heat radiating from inside hitting her like a wall. His maw was a grotesque blend of smooth metal and slick, almost organic material, the soft lining glistening as his fuel system prepared to receive her.

“By the time I’m done with you, they’ll have to check dental records if th-”
“Is this like Decepticon Kayfabe or something?” Something had clicked, she was still terrified but she had to fucking ask. If she was going to die like this she wanted to at least try to understand the logic.

Surprisingly, he didn’t frown or lash out at her for breaking whatever illusion he was trying to maintain for, but relaxed his shoulders a little.

”Not quite. You’re close though. Keep guessing if you’d like…” he purred then winked at her.

The heat intensified as he brought her closer, the humid air inside his mouth felt suffocating. Jessie kicked and screamed, but it only seemed to please him more so she stopped. His grip was iron, his touch unyielding. He wanted this—wanted to feel her body inside him, wanted to enjoy her as she was broken down, piece by piece.

“You should feel honored,” Overlord said, his voice a low rumble as his tongue flicked against her legs, teasing her with the inevitable. “Not everyone gets the chance to be so… useful.”

Jessie’s mind raced, her pulse thundering in her ears as she realized there was no escape. The heat, the wetness, the slow, deliberate way he was drawing this out—it all felt too real, too visceral. At conflict with his words but definitely happening. She could feel the rumble of his systems, hear the churn of his internal workings preparing to digest her alive.

The acidic scent of his internals hit her nose, sharp and overwhelming, as his mouth opened wider, ready to consume her whole. The soft, slick walls of his fuel chamber awaited her, eager to churn her down into nothing more than biofuel. The hoses and pipes inside his body shifted, preparing to pull her deeper, into the dark, wet confines where she would be slowly broken down, every part of her absorbed into his power-hungry frame.

And with one last, twisted grin, Overlord shoved her headfirst into the darkness.

Chapter Text

Overlord’s mouth closed with a satisfying finality, sealing Jessie in complete darkness. The thick heat of his body wrapped around her, the soft, slick walls of his throat pulling her deeper into the furnace that awaited below. Her kicks were frantic, her fingers scrambling uselessly against the soft, slippery surface, but it was pointless on her end. He appreciated it though, the struggle honestly got him going quite a lot. He wouldn’t be doing this for just one human on a random space station in the middle of the night if it wasn’t a good time. Jessie could hear a muffled click, it was loud and the sound came from both lower in his body and from outside of it at the same time. She had been on the right track with the guess, and he was definitely preforming for an audience. 

Overlord eyed the stream chat on his HUD and smirked before cutting the shot from the hacked station security camera to one of his internal cams showing an infrared view of the inside of his mouth. Chat flooded with messages starting the bets on how long the human would last, and requests for things they wanted to see him do with his tongue. 

He started to lick her all over, honestly he could care less about chat at this point he just wanted to enjoy this. Sure it was a commissioned stream, and he stuck to the angle that was asked for as much as he could for the guy, but in the end a snuff film is a snuff film. As he toyed with Jessie’s body, each squeeze pressed the air from her lungs, the hot breath of Overlord’s body drowning out everything except the wet, slurping sounds of his internals working her deeper inside. He bit his lip and moved his hands down to his spike, and started to stroke slowly. He didn’t take commissions often, it was less a money thing and more an aversion to people pleasing, but this one had caught his interest. Some long story about how it was intended as a gift to someone that would cause conflicting feelings about something, blah blah he didn’t actually pay too much attention. The part he paid attention to was that the Con wanted him to eat only one very specific human because it would fuck with their ex who had ghosted them. He understood that, the situation felt relatable to one of his own experiences, and a bit cathartic to do something for someone who would probably get a response from the ex they were fucking with. Overlord could be nice sometimes. 

The wet heat of his mouth was oppressive, the slick walls pressing against her as he held her there, savoring the taste of human made oils and other substances from the shop she worked in that lingered on her coveralls. The rhythmic, mechanical hum of his internals seemed to grow louder as his systems came alive, ready to convert the fragile life inside him into raw fuel.

She kicked, screamed, her hands pushing desperately against the slick surface of his tongue, but it was no use. The powerful suction of his throat pulled at her, dragging her downward, deeper into his sensitive fuel intake system. The cables in his throat—soft, deceptively smooth yet unyielding—flexed and contracted around her, pushing her inch by inch towards the waiting depths of his fuel chamber. She could feel Overlord stifle a small moan around her in his throat.

Chat caught on to what his hand was likely doing and Overlord pulled out a small camera drone so he could give them a view of his spike too. His massive balls filled at least half of the frame and he put on a bit of a show massaging them. It was part of the “Phase Sixer” fetish for a lot of them, it wasn’t a very common mod before his vids started popping up online. He had half a mind to just reach into the little bar the human in his tank had come out of to see is she had any friends in there. It was always hard to just have one prey at a time, his transfluid tanks ached as he played with them and longed for the heavy feeling of having them nice and full of struggling-XxSLAGSUCCer69xX sent 50 gift subs… the words flashed on his HUD and he cringed waiting for the-“PLeaSe make the throat and fuel tank cams larger on screen, love ur balls though xoxo big fan sorry daddy” the TTS droned and he obliged. Chat spammed some emoji and Overlord rolled his optics then started watching the live feed from of his internals as well. He could feel everything, he didn’t need to see it to enjoy himself and get lost in it… he really did need to find a producer to manage the nerd shit for him. 

Jessie’s world was consumed by heat and motion. Her body was compressed from all sides as Overlord’s throat worked her down, the tight, suffocating tunnel squeezing the air from her lungs. The deeper she was pulled, the hotter it became, until the heat was unbearable, the moisture clinging to her skin as if she were sinking into a living furnace.

With a slow, deliberate swallow, Overlord pushed her the rest of the way down, a satisfied hum escaping him as he felt her drop into his fuel chamber. It was soft—disturbingly so—the silicone-like walls flexing as they accepted her. She landed in a shallow pool of fluid that immediately began seeping into her clothes, clinging to her skin with a burning sensation. The air was thick with a sharp, acidic tang, almost too heavy to breathe.

Jessie’s body was gripped from all sides as the chamber flexed around her, squeezing her into the waiting pool of corrosive acid that began its slow, brutal work on her. The slick, pliable walls pulsed, pressing her deeper into the fluid, which hissed and bubbled as it ate through her clothes, her skin. She screamed, thrashing wildly, god he loved how biofuel struggled. The moment a flesh-bag was in his mouth they just counted as fuel in his book. Hell, even before that, especially humans. The way Autobots made friends with and protected humans was so funny to him, they were much more useful as just, fuel. Fuel that felt really good... 

The acids of his pink alchemy modded Phase Sixer fuel tank were slow, cruel, and good at burning away human flesh inch by inch, turning everything they touched into a soft, gelatinous mass. Shockwave was a nerd, but a nerd who knew exactly what the fuck he was doing when he developed the entire fuel conversion system that Overlord was currently live streaming to the niche group of perverts. As cold and calculating as Shockwave could be, it was hard to tell if the idea was purely utilitarian or born out of some millions of years of energy focused nerd fetish bullshit. Overlord wasn’t sure, but he felt like half of Shockwaves creations and innovations were utilitarian in nature at the start of development, then obsessed over to a level with such focus that they became kinky? Logically they stood as cruel and incredibly useful, and as long as inventions were useful Megatron usually was into it. Phase Six of his infiltration protocol called for warriors who could wipe out entire populations. Shockwave being ever the efficient freak that he is, felt like he could indulge by Overlords count… probably 10 or more of his kinks at once and make committing an atrocity at that scale both fuel efficient and absolutely fucking terrifying to organics.

Surgical modifications, fuel efficiency studies, torturing flesh bags for data, melting organics into something actually useful instead of annoying, psychological warfare… he likely was grooning for years working it all out in his nerd lab. He may have had everyone else fooled but Overlord knew a fellow freak when he met one. Not that he felt any need to prove any of this… he just found it hilarious. 

The way Cybertronian culture developed fetish content around constant innovations in warfare was always a fascinating topic, one that had roots way older than the war itself. Honestly the human in his stomach wasn’t too far off with their comment about “kayfabe.” Downloading the cultural context of the word for translation when she asked, it took him back to his Gladiator days and it wasn’t often that fuel made him reflect on that… 

Overlord snapped back to reality after remembering her. He had meant it sincerely when he called her fortunate. She was smart enough to work out part of the dynamics at play involved in fetish content that had been developing into what it currently is for millions of years on a world so far from her own. She was a human who had traveled across the stars so far from her home, but in the grand scheme of things had a life that lasted for only a blip of time, if left alone she would die without hardly leaving a mark on history by any measure that would make much sense to a Cybertronian. 

Instead of letting her be relegated to existence without even a hope of legacy, Overlord was putting her to use. Very crude and intentionally disrespectful use, but use nonetheless that would be archived as fuel for his own legacy.

A legacy as a gladiator turned indestructible Decepticon super soldier… turned sex symbol whose war crimes changed the historical course of Cybertronian fetish content. By his estimate her existence would be cited in archives of sexual history for years longer than her species would probably survive for—“Cock and ball torture (CBT) is a sexual activity involving application of pain or constriction to the male genitals. This may involve directly painful activities, such as genital piercing, wax play, genital spanking, squeezing, ball-busting, genital flogging, urethral play, tickle torture, erotic electrostimulation or even kicking. The recipient of such activities may receive direct physical pleasure via masochism, or knowledge that the play is pleasing to a-“ TTS once again snapped him back to the present. 

He hates his chat sometimes. This isn’t one of them though, he’s honestly amused whenever fleshbag memes make it into his streams, he even plays along sometimes. The rest of chat spams curses in Neocybex with no human translations as Overlord switches the focus to the camera drone pointed at his balls-“Contents: Section 1: In Pornography Section 2: BALL STRETCHER Section 3: Parachute Section 4: Humbler Section 5: Testicle cuff” he spends the rest of the donation tts shitpost rubbing his balls on the camera drone while half the audience starts trying to trick the donor into saying something they could use to dox them. His chat is horrible, it’s great.

Overlord groans when he hears his fuel tank make a gurgling sound so lewd that he clips it to listen to again later. Slowly his charge level starts to rise as he feels motions his frame has become conditioned to loving, the prelude to the actual energy absorption part of eating an organic. 

The sound was grotesque—a wet, bubbling gurgle as her body began to break down, the fluids sloshing as her form softened under the unrelenting churn of the fuel chamber. Every movement was accompanied by a squelching, sucking noise, as the acid slowly melted her skin and muscles, converting them into a thick, goopy slurry. The walls pressed in again, flexing in a slow, methodical rhythm, ensuring that every inch of her was exposed to the corrosive liquid.

Overlord groaned in satisfaction, his optics dimming as he savored the sensation of her body dissolving inside him. The walls of his fuel chamber continued to churn, kneading her form, pushing her deeper into the bubbling mixture. His systems hummed to life, the first trickles of biofuel beginning to flow as her liquefied flesh started pumping into the network of hoses and conduits that lined his internal systems.

Inside, Jessie’s screams grew weaker, her body trembling under the relentless assault of the acid. Her legs had gone limp, the muscles slot dissolving into a thick, gelatinous mess that slid against the churning walls, making soft, sickening squelching sounds with every contraction. The acids were deep in her skin now, searing through her muscles, bubbling up around her as her body began to lose chunks of its solid form. Chat always loves this part, the vote from earlier about how long this would take is close to being decided and that always makes them rowdy. 

Her mind was fading, the pain overwhelming her senses as her organs began to fail, melting into the growing pool of slurry. She could hear the wet slosh of her own body breaking down, the fluids gurgling and hissing as they churned her into something unrecognizable. The walls of the chamber pulsed again, pressing her liquifying remains deeper into the digestive fluids.

Overlord’s fuel chamber gurgled softly, the wet, goopy sounds of digestion filling his internals as Jessie’s body was churned into a thick, nutrient-rich slurry. Her consciousness flickered for the last time, her mind overwhelmed by the searing heat, the crushing pressure, and the wet, bubbling sound of her own body dissolving.

And then, she was gone.

Overlord let out a deep, satisfied groan as her consciousness slipped away. His body shifted, adjusting to the sensation of her liquefied remains being pumped through the complex system of hoses and pipes that lined his fuel chamber. The slurry of her flesh and organs sloshed noisily as it was sucked into the network of tubes, where it would be converted into pure biofuel and either immediately burned by his system or stored in an auxiliary tank.

The final traces of her form sloshed softly as they were pumped through the tubes, the last echoes of her existence fading into the wet, gurgling depths of his internal network of tubes. Her bones, stripped of everything, were nothing more than debris now, the last remnants of a life consumed and digested.
