Berth Warmer

Summary:

Starscream claims he still has some use left in him but Soundwave is still skeptical on believing him.

Notes:

Dub Con tag is because Starscream likes to talk a big storm when having sex, but won't follow through sometimes and Soundwave knows how his partner can be, so he makes him eat his words (Star won't openly admit it, but it's fine if Soundwave gets like that, he's into it)

So while they don't outright discuss their intentions with each other in the fic, they have had discussions about it before between the both of them. They know and understand the other's limitations/when to actually stop. They carry on with that implicit understanding while not out right stating or mentioning it.

Work Text:

Maybe Soundwave should’ve seen it coming, but after Starscream had created another failure and earned himself another inevitable lecture from Megatron about why he shouldn’t waste their precious resources for stupid ideas. He ended up witnessing and handling the aftermath of another shout match between his leader and his fellow Decepticon commander.

Starscream had his head in his servos like usual, stomping his pedes against the ground, slamming all sorts of different but creative insults towards Megatron’s vanishing back. He didn’t seem to mind his current situation of being trapped in a cage for punishment either. The electric cage sparking all sorts of noise, daring to electrocute anyone who touched it from the outside or inside.

As if none of it mattered, Starscream continued to scream at Megatron while his fellow seekers, Thundercracker and Skywarp told him it was a lost cause to shout before they too took their leave. Yet despite being the kind and well natured advice, Starscream managed to list all of things that related to Megatron’s apparent faults. Things like his old age, his stubbornness to not listen to anyone if he thought it wasn’t needed, and his dumb obsession with Prime of all bots.

Soundwave thought it was just like any other useless squabble between Megatron and Starscream, maybe it was entertaining to listen to the first few hundred times he had to witness and supervise, but after a while he got bored of just watching and listening.

So, he openly laughed at Starscream’s pain once the room cleared and it was just the two of them alone glaring at each other. But after enjoying the delightful sight of a pitiful Starscream, he decided to be kind by releasing him from his cage, a little earlier than Megatron had planned because after some deliberation Soundwave felt it would’ve been better to let his accomplice out despite how annoying he could be.

“How dare you!” Starscream said, howling. He stood up almost immediately the moment he realized Soundwave was still laughing at him. He had a deep frown on his faceplate. “I am a useful, vital, and necessary part of this faction. It would fall apart without me. You need me,” he yelled.

“Argument considered but concluded to be invalid,” Soundwave said, refusing to stop his laughter. He crossed his arms across his tape deck and started to head out with a backhanded wave. “The Decepticons survival depends on Soundwave’s expertise to keep us running and not Starscream. What exactly does Starscream have to offer? Nothing.”

“You’ll see!” Starscream said, proudly. He ran after Soundwave, approaching him with languid ease as the conversation continued between them. “No, I’ll show you what I have to offer."

Soundwave stopped walking after hearing Starscream’s challenge. He smirked underneath his mouth guard when he felt the seeker slam into his back and glare up at him with a sneer plastered all over his faceplate. They continued to stare at each other like that. One side furious with an air of posterity and one side full of disguised intentions.

Starscream’s flushed cheeks looked pinchable, but Soundwave dismissed those desires the moment he heard what Starscream was thinking about. He was thinking about letting the depravity between them run a little looser than how it usually went, test how far he could get away with embarrassing his subordinate. Starscream even leaned forward to stare at him through his red visor, the action made Soundwave chuckle, that thought was on purpose.

“Soundwave will have to wait and see what Starscream comes up for him then.”

“Don’t blow short fuse when I knock your panels off then,” Starscream openly declared at him. He pecked at Soundwave’s mouth guard, sauntering off with a sudden pep in his step, flutter of his wings. “Because I will make you change that tune of yours!”

Soundwave watched him leave with a head tilt, but brought a servo upward to touch where he had been ever so lightly kissed and rubbed it off with his thumb as if that would erase the subtle thump in his spark and the desire he had felt earlier when looking at Starscream. Leaving the seeker to his own devices would’ve just given him more time to plot or cause more trouble. It always did and a Starscream who had either of those options was a far worse opponent to deal with, maybe an even worse opponent to stop. Soundwave had always found it was easier to earn a few sweet energon points with Starscream by letting him believe he had the upper servo between them because then the seeker would listen to him more instead of his usual guns-ho attitude.

Starscream could be a fool, but he wasn’t that much of a fool. He made a decent second in command if he put his pride to it, however, it only worked out that way if Soundwave put the effort to corral and coerce him with a desire to give him attention. Handling Starscream was like leading a horse to water. You couldn’t force it to drink, but you might be able trick it like a donkey with a carrot.

Soundwave started to debate if this newly established war between the both of them would cause the two of them trouble as he went on with his day and had lunch with his cassettes. Occasionally, he would look over his shoulder expecting Starscream to be behind him, or steps away from, but he wasn’t. The most he would do is stare at him from afar, toss a flirty wink, maybe even stick the tip of his glossa out at him as if to ask if this is what he wanted. If Soundwave wanted a taste of him all while refusing to put his pedes forward to move and take him for a spin.

None of it came across as something out of the ordinary to him, however, Starscream had returned to his duties like usual instead of bothering his personal space. Until Soundwave walked into his surveillance area and saw the last thing, he could’ve ever expected to see which was Starscream leaning over his console with his aft in the air and his head turned back towards him. He was smirking.

“Oh, sorry,” Starscream said, slyly. “Did you need to use this room?”

Soundwave shook his head to dismiss what he had heard, but he also took a step forward to approach his now blocked off console, or rather Starscream’s aft. Slowly but surely, Soundwave pushed and pressed his digits up against the red metal object, forcing a sudden squeak and guided moan out of the seeker as he began to kneaded the area. It was probably still inflamed from their little sudden rendezvous at the club. Starscream had pressed him up against a control panel like this one and insisted on risking a little fun. They had a two-way window and all the time in the world to mess around while the humans were hypnotized by his music and Soundwave agreed. The danger was fun.

However, despite Starscream’s latest scheme to distract him from his current task at hand, Soundwave continued on with his work. He used one servo to nudge Starscream ever so slightly off of his console, but not to the point of forcing him off of it. Starscream seemed to pick up on his intentions to mess with him and tested the limits by pressing his aft even further into the palm of Soundwave’s servo, sitting on it almost as it was delicately breached by a distinct set of familiar blue digits.

“Pervert,” Starscream muttered, but he didn’t move from where he had arched. He just peered up from where he was with a flirty expression and watched as Soundwave used his free servo to type the data and files he must have been planning to enter and view into the console.

“Starscream was the one who offered his aft,” Soundwave replied. He wouldn’t deny the twitch his digits felt from touching the seeker, or his aft, slowly the tips of his digits follow the plating and shape of the outlines, the confines of it. Starscream must have had buffed it recently and added that fancy polish he liked to use for him.

But Soundwave’s optics remain on the screen in front of him. “Starscream is simply reaping what he sowed and challenged Soundwave on earlier with his thoughts.”

A whimper escaped Starscream’s throat and his optics began to become glassy with a spray of coolant. He was frustrated by the mere cupping and rubbing of his aft, lower back, and wings. His sensors had been barely breached; the threshold of pleasure deprived from him each time Soundwave changed how he had been touching him.

Starscream tried to keep his movements silence, ignore the heat that built in his panels, or the idea that he had already started to leak through his metal, making a mess on the floor. The last thing he wanted was to hear Soundwave scold him for dripping pink trans fluid everywhere, yet at the same time, he wanted to be scolded.

As that thought hit his processors, Starscream opened his mouth about to make a noise, but swallowed it before it could escape. He leaned his chin on Soundwave’s shoulder and stared at him. Did he want to be swallowed whole by Soundwave right now, or did he want to swallow Soundwave whole first? The first gulp he manages to take after squeezing his thighs and wings together. The first pant he manages after seconds of merciless touch. Finally he gathers the strenth to puff his chassis out and look at Soundwave with a deadly glare.

He can sense the smile that must be on Soundwave’s faceplate despite not being able to see it. He can sense the subtle crinkle in Soundwave’s optics despite where his visor is pointed. Starscream refuses to believe this bastard wasn’t enjoying this type of scenario—something that would always have no long-term solution between them. There was a sense of loss to his spark when Soundwave pulled his servo away to type a full report on his console, exposing his clean servo. He was now documenting what resources they had left for the week.

“Yet to still see why Starscream is meant to be considered useful,” Soundwave said. “Let alone a vital and necessary part of this faction like promised.”

“Just you wait,” Starscream said, shuddering. He stood straight up like a ruler and brought his servos together in a closed fist. “Just wait for tonight, Soundwave!”

They both knew this little came of theirs had no real winner in it, but still they wanted to play the other like a fiddle until the end. Soundwave came into his quarters expecting that for the most part. But he didn’t see Starscream, not even a sign of a disturbance.

As he walked around the room, Soundwave started to check any potential hiding spots, slamming the door to his bathroom and closet open, half expecting to see a caught off guard Starscream hidden away in there, but like before when entering his quarters, he didn’t. He saw nothing out of the ordinary. Soundwave thought that was a little strange and went to lay on his berth. His cassettes had already been ejected and told to stay out of his quarters in preparation for what Starscream had told him to wait for, whatever tonight was supposed to have entailed for the both of them.

Starscream was in his quarters more often than not. He was in it more than Soundwave himself even. An outlandish, unrepeatable fact that ever since they started to interface and flirt with each other more, Starscream had started to recharge with him more, or borrow his living arrangements to do so. Soundwave would inexplicably become used to the sight of a seeker recharging on his berth before him, hardly budge or grow embarrassed when he read a thought about them fragging somewhere indecent. Starscream had never been shy about it.

But neither was Soundwave, with his touches, backward glances, and invited handling. He accepted the inappropriate nature of their relationship, if it could even be called that. It was more like a secret affair between co-workers. They never did bother to put a label to it.

While Soundwave was lost in thought and bored on his berth. Starscream came sauntering in with his wings behind him. He snorted at his companions stiff and wooden plank like demeanor, but climbed on top of Soundwave like it was a seated throne with his name on it.

“Bored all by yourself handsome?” Starscream said, staring down at Soundwave. He had his servos on his hips and a wide toothed grin on his faceplate, admiring the reflection of himself he could see off of Soundwave’s visor. He looked good. “Or were you waiting for little old me?”

“Starscream talking to himself or Soundwave here?”

“If you can’t tell by now, I should just go,” Starscream said, sneering. “Of course, I’m talking to you. Who else!”

Soundwave remained where he was, watching as Starscream lowered his upper body and placed it on top of his and smushed his cheek against the door of his tape deck, but then Starscream brought his servos backwards and towards his aft as if to hint at something.

“This is how Starscream intends to prove his worth to the Decepticons?” Soundwave said, dumbfounded. “By being Soundwave’s personal berth warmer tonight?”

“If that’s what you want to call whatever this sure let’s go with that,” Starscream mumbled, pulling his servos forward and to his side. He pressed his palms against the berth soon after as if to ground himself. “Take it or leave it.”

As Soundwave’s servos reached over to touch where Starscream’s servos had been, they gravitated to the seeker’s aft, subtly surprised to feel his valve was already out and exposed. Tenderly, Soundwave teased it with the tip of his digits, eliciting a few whines from Starscream, who began to pant and glare at him. With a hidden smirk, Soundwave ignored the clear and visual warnings that came from the seeker—following the once hidden and narrow entrance into something much more welcoming and patient by spreading it wide open until he heard a sharp moan.

Starscream burrowed his faceplate into Soundwave’s neck the moment he felt his valve and in turn aft were stretched and glided against by thick weathered digits. He could barely whimper anymore as Soundwave began to delicately trace his valve, aft, lower back, and wings. Treating him as if he were a work of art to be treasured.

The edge of his wings was where he was the most sensitive due to the thinness and durability of the metal, Soundwave knew that best—and all Starscream could do as they were pinched and scratched was shudder and accept what he had called to take control of his frame. While clenching his teeth and servos, Starscream thought since he had gotten himself in this mess, he would ensure his victory as well.

“No spike?” Starscream asks. After a few shallow nibbles, Starscream sunk his two front canines into Soundwave’s neck, the edge of his tape deck and his mouth guard. He smirked while looking the bastard in the optic, thinking about what else he could ruin from this position until he was spanked.

“How dare you. Not even my own carrier dared to smack me there!” Starscream yelled out. His optics had widened due to the shock of being spanked like that. He was more than used to being struck by Megatron for failing him, maybe even trained to accept whenever Soundwave decided to grope him and his aft, however, he had never been struck there before in the berth.

Soundwave ignored him and did it again. This time harder far harder. He even stared up at Starscream and laughed, doing it a third time. “Starscream is the one who still has to prove that he has worth to Soundwave by being his personal berth warmer. Not the other way around.”

Starscream lowered his faceplate and puffed his cheeks out. He looked like a riled-up puffer fish to Soundwave with how he glared at him. A blown-up puffer fish could be endearing if not for the deadly poison and sense of danger that came with such an appearance, Soundwave thought.

“Well, I can’t do any sort of warming if you don’t give me something to work with,” Starscream said, angrily. He refused to move and continued to glare at Soundwave as if that’d satisfy his anger over being spanked so suddenly, anything to ignore the flow of trans fluid he had felt when it happened.

“Starscream wants to give a show?” Soundwave asks.

“Duh,” Starscream sneered. “What else am I here to do?”

Soundwave removed his servos from Starscream’s aft and propped his elbows up. Like asked he exposed his spike and sat back to witness the show, but Starscream seemed confused about something. As he stared at him, waiting to be lifted and given an easier start.

“You expect me to put it in myself?” Starscream exclaimed. “No way—”

“Starscream can either put it in himself or go recharge elsewhere from now on. His choice,” Soundwave said, cutting him off.

“Fine, fine. You want a show?” Starscream said, upset. “I’ll give you one, Soundwave.”

Starscream took a deep intake cycle and turned back to stare at the spike in front of him from where he was still laying down. He had two options either take advantage of his current position of where his valve was and use that to take in Soundwave’s spike, or sit up and lower himself on it that way.

After forcing the lump in his throat to go down, Starscream began to slide himself onto it and helped guide himself into Soundwave’s spike. He bit his lip in an attempt to disguise and hide the gasps from his vents as he slid his waist downward in a slow, but steadily paced motion, taking in the thick and heavy object before him. With a groan, Starscream had his head turned back to watch until he had completed his assigned mission before smirking at Soundwave who rewarded him with a simple pat on the head.

“Good job,” Soundwave said, calmly. “Starscream did good.”

“Because I’m me,” Starscream added. “Now lay down and keep those servos on the berth. No touching allowed until I say so—!”

Soundwave let out a firm chuckle, but did as he was asked. He left his servo on the berth despite the twitch in his digits to grab Starscream’s waist as he started to position himself on top of him and swing his legs until they were, on either side of his thighs as well. It took a little bit of maneuvering and a few slaps in response to the servos that snaked his way, but Starscream seemed to have gotten where he wanted to be—a shallow but hearty ride set at his own pace.

Starscream gasped as he started to move his hips to take more, sliding up and down Soundwave’s spike, shuddering as his node was given a direct one-way gate to direct contact on warm metal and the intricate shapes of Soundwave’s buttons. Though Soundwave remained quiet, Starscream could tell he was enjoying himself from the tilt in his head. How it was cocked to see the most.

Soundwave also had his digits digging into each other and his visor focused on the door to his quarters as if worried someone would accidentally walk in on such an illustrious sight. With a loud scoff, Starscream increased his pace by pulling and slamming himself back onto Soundwave’s spike, moaning as he felt how slick it was now, drenched in his own trans fluids. Dyeing the both of them in it, but if that’s what it took to make Soundwave give in first, he would do it. They were similar like that.

Starscream felt something begin to coil and the pleasure he felt from his node funneled any desire he had already been feeling, it caused him to chase the majority of his induced and stimulated high as his lower wires continued to tightened. He was about to choke on his own jet fuel and coolant. The closer and closer Soundwave’s spike got to breaching his forge, sticking to it, the more it teased his forge, the more he wanted to stuff himself with it.

Perhaps even more when combined with the angle he was positioned. Following his instincts, Starscream pressed his canopy onto Soundwave’s tape deck. His nose made its way into a neck, mewling into it as Soundwave continued to rub the back of his head. As the curve of Soundwave’s spike started to edge his forge, Starscream forgot to maintain his composure, how loud he got, and overloaded without a care for his companion’s pleasure, just his own.

“Starscream is enjoying himself isn’t he. Forgot what his original mission was supposed to be,” Soundwave said, peeved. “What a slutty berth warmer he is.”

He had managed to find a loophole in Starscream’s words. Starscream had only said he couldn’t touch him, but he hadn’t said anything about not being allowed to use his lower frame to fully thrust into him, so he did just that. Forcing Starscream to arch his back and pull himself up, thrash a little due to the sudden change of angle and speed. It was no longer on him to solely move, now he was battling with Soundwave, his hips, and himself for control.

“A massage stick could frag me better than that!” Starscream exclaimed. He moaned even louder when Soundwave pushed himself up on his elbows to glare at him. Starscream could sense how upset that comment had made his companion and laughed. “Yeah, that’s right, my toys frag me better than you and all they have to do is sit there, Soundwave.”

After being compared to a simple toy and insulted by it, Soundwave stared at Starscream and grabbed his hips, deciding to dismiss the initial command he had been given to not touch the seeker. It stopped mattering to Soundwave the moment Starscream had decided to go to such great lengths to insult him.

“Starscream talks too much. He’s forgotten his place,” Soundwave said, annoyed.

“Please,” Starscream said, sneering. “I’m on top of you, aren’t I? Who has forgotten what.”

Starscream let out a sharp yelp as Soundwave gripped his aft, digits digging into it—and pulled him off of his spike—up to the tip of it as if to pull it out with a loud pop—before he was momentarily slammed him back down onto it, hitting the edge of his forge without hesitation, bordering it. The near pinched slit of it, almost breaching it open further.

With a shallow growl, Starscream could only grip onto Soundwave’s shoulders and hold himself up, the tip still pressed against his entrance, teasing the now stretched area. Despite the shaking in his servos Starscream scrunched his faceplate and pleaded to be given some sort of leniency.

“I didn’t mean it,” he said, flickering his optics to see Soundwave had decided to spare him another round of torture—for now.

Maybe he didn’t what he had said. But there was the undeniable feeling of digits that gripped and slapped his aft before moving onto his fluid covered thighs. Starscream whimpered as it continued to gush out and onto Soundwave. However, he his mind was too hazy to care, normally he would’ve minded the sticky sensation, but right now he wanted to make a bigger mess. Make Soundwave give in first by acting cute.

“Starscream didn’t?” Soundwave said, snorting. He didn’t believe that for a click and continued to massage Starscream’s aft, optics trained on the wings that fluttered before him and the shake of his pedes. He felt like pinching something again, or putting his spike back in as it twitched due to the change in environment. It was getting cold and he was starting to miss where it’d been earlier already.

“No,” Starscream said, pouting. He put his servos across the side of Soundwave’s mouth guard, raising the pitch of his voice. “When have I ever meant what I said…you know how I am by now, Soundwave.”

“That’s true,” Soundwave said, slowly.

Starscream smirked, thinking that he had managed to turn the situation back in his favor, but that feeling dissipated the moment he sensed Soundwave’s spike start to press up against his seal and enter—pushing his mesh apart and to the side. Its arrival eased by his previous overload and any trans fluids flushed down by his systems.

“But Soundwave also knows Starscream likes to talk a big game and be taken advantage of sometimes by him. He likes to claim he’s done, but really he’s not.”

“Hold on,” Starscream said. He tried to escape, but his waist was grabbed and Soundwave angled his hips with a sharp thrust forward, trapping him. "Soundwave, let’s think this over. Recharge, please.”

“If Starscream can still beg for recharge then he can stop being selfish and remember that Soundwave hasn’t overloaded yet. Only him. Meaning Starscream can more than enough handle another round right now,” Soundwave said, deaf to his companion’s pitiful expression by now. “His mission not accomplished yet. He can and will keep going.”

"You—" Starscream hiccuped.

Soundwave ignored him and continued the assault on Starscream’s already dented hips and paint marked aft, taking advantage off their position. Starscream was rocked and glided up Soundwave’s fully grown and now fully barbed spike.

As it continued to drag and scratch up his tight mesh wired walls, Starscream could only shudder and moan, clawing Soundwave’s shoulder canon, shoulders, and door to his tape deck.

Too deep that was the only thing Starscream could recall saying by then to Soundwave, amidst every other hoarse wail or plea for them to take a break. He was going to snap in half at the pace they were going. Soundwave would say he should’ve thought about the possibility of his frame being abused like this before coming to his berth.

"No more, Soundwave. Mercy please, my dear... Anything?"

“Starscream can stop when Soundwave has decided he can,” Soundwave said. He sounded rather monotone and capable of more in comparison to his companion, who remained out of intake, his wings twitching with every new overload, or dent in his forge. There was even a bulge by now, if Soundwave looked at Starscream closely enough.

“I said, I was sorry—” Starscream whimpered, but was cut off as he felt his blue mesh walls tighten around Soundwave’s spike again and another heated gush of fluid shot up his valve as he overloaded. By now he could see the sun starting to rise from the corner of his optical field. Recharge was starting to set in his frame, he really couldn't take anymore of Soundwave’s torture. 

Starscream moaned slowly and dropped his head into the crevice of Soundwave’s neck, pressing his nose into it for comfort. He bit at it after, vowing to openly to ruin his subordinate for his most recent and punishing actions. He was completely and entirely exhausted. Soundwave had insisted on using him to the fullest and did. What treachery, Starscream thought. But he also thought how nice it felt to see Soundwave express himself, it was boring if not.

Despite the constant gnawing or bites deep into his neck, Soundwave remained calm. He reached a servo forward and began to slowly stroke the back of Starscream’s head. Soundwave felt he had finally eaten enough of Starscream and was willing to let him rest. It's morning already, he thinks. The rays of sunlight bouncing off of his visor, and he lets Starscream’s weak feeble frame relax on top of him a little more. Soundwave spreads his free servo out to relax, but he didn’t remove his spike from the seeker. Instead, he let it stay inside while Starscream continued to bite at him, drawing pools of energon from his neck, yet with how tired he was, Starscream was barely able to lap at it with his glossa. Too tired to remove himself from Soundwave and his spike, but feeling vengeful nonetheless by drawing energon.

“How’s that for a berth warmer?” Starscream said. His voice hoarse from moaning and yelling all night. He could already feel the painful needle like sting that was coming his way when he came online later. Maybe Soundwave would too, he hoped.

Soundwave stared at Starscream from beyond his visor. He looked at the big red optics full of hidden love underneath, exposing his companion’s true thoughts from their time spent together and possibly towards him.

“Acceptable,” he responded, almost happily. Soundwave continued to rub the little vents on Starscream’s head, thumbing them while the seeker let his engines emit a purring sound and his optics began to slowly go offline. “Starscream did good. He has proved his usefulness to Soundwave for today.”

“I told you, Soundwave. I’m a valuable member to this faction. No, to you!”

Soundwave said nothing, but he did pull Starscream closer and pinched his cheeks like he had thought of before. Maybe he just liked the thrill of this person forced to lay on top of him, maybe he just liked to see how he came apart so fiercely because of him, yet deflated in an instant if left alone. Like an angry stuffed puffer fish.

Either way he liked having a new berth warmer even if it had already been long decided and accepted as the norm between the two of them as they recharged together. Like they always had done. An almost unanimous decision. They liked to take control of one another.
