Chapter Text
Of course, Knock Out had to have set very specific rules for them (*cough* Megatron *cough*).
Like for one, jumping Starscream out of nowhere did not count.
Megatron, personally, thought that was bullshit. But Knock Out said that if he did attempt to do that he would be disqualified and would be forced to watch everyone else fuck Starscream and Megatron knew well enough to not do that.
So he would have to wait for the perfect chance to get Starscream alone which was actually easier said than done.
Because every time Megatron thought he found his chance to pounce, suddenly Starscream was doing something or Knock Out was having him run an errand. (that bastard. If not for the rules he set up the warlord would have torn his helm off a long time ago)
It was like the universe was taunting him.
Megatron was going to die from blue balls (see that Knock Out, he could understand Earth slang too! He’s still banned from the internet though) before he even got a chance to defeat the Autobots.
And then as if Primus decided to take pity on him, finally, finally , he found the perfect chance.
And this time Knock Out would not sabotage him.

Megatron and Starscream were arguing, what else is new? The sky is blue, the grass is green, Megatron and Starscream hated each other, just the natural course of life.
But this time… the air around those two were a little different. Especially around Megatron.
Those who were paying attention closely would notice the flitting glances at Starscream’s frame, more specifically his hips and aft. Those who listened in carefully would almost think that they heard a seductive lilt to Megatron’s voice when he spoke to Starscream.
It was very odd.
And this slight mood change did not go unnoticed by Starscream.
Suddenly he would drop subtle flirts here and there, his walks would add an extra sway to his hips, his wings would flutter enticingly, he even batted his eyes at Megatron once.
Now they were arguing again, this time in the throne room where they were all alone. By this point, Megatron didn’t even care what they were arguing about anymore, he was just focused on checking out Starscream’s body. The seeker didn’t even seem to notice that the warlord stopped talking to leer at his body, he just kept on ranting.
His optics raked upwards, starting from his long, slender legs, to his wide hips, to his curved waist, and then to his chassis and wings. He repeated the process, but downwards this time, going over his wings and chest again to his legs and doing it over and over for five more times until Starscream finally noticed. His voice died off as he noticed what Megatron was looking at, optics widening in surprise and nervousness.
Truth be told, Starscream sort of felt like a large chunk of energon with the way Megatron was looking at him.
Trying to cover up his uneasiness, he sneered at him. “Like what you see, Megatron?” He sneers, placing a servo on his hip.
“Yes, actually.” Was his quick response.
Starscream blinked in surprise and then felt his faceplate heat up in a flustered blush. He wasn’t actually expecting Megatron to own up to it. “Oh.”
Megatron stepped forward and loomed over the suddenly awkward seeker with a seductive smirk playing on his dermas. “Don’t tell me you’re all shy now after all that propositioning you were doing?”
Starscream took a step back. “I.. Uh..”
Megatron leaned in very close, so close that their lips were almost touching and Starscream had barely managed to stop himself from flinching. “Your charge is running high.. I can almost taste it on you.” He purred. The beginnings of lubricant began to build up in Starscream’s valve from arousal that he so desperately tried to hide. “How about we both work together for once here. I help you relieve your charge and you show me a good time? It will be very beneficial to us both..” His voice was low and seductive, his optics darkening with lust.
Starscream looked oddly vulnerable and uncomfortable, and though the promise of interface was enticing, he wasn’t sure if he wanted his first time to be with the mech that he tried to kill multiple times. “I don’t.. I’m not sure..”
Megatron almost snarled. “I assure you, I am very experienced with this sort of thing. I won’t hurt you.” It was probably a lie. With their size difference, it would probably end with Starscream getting hurt in some sort of way.
The seeker still looked unsure. “But.. I don’t know how..” That made Megatron confused for a moment and he processed it for a moment before it clicked. “..Are you..? Do you still have your..?”
Starscream nodded silently, suddenly looking a bit afraid. What if Megatron was furious that he still had his seals? Would he punish him for that?
Internally, Megatron was doing a backflip.
He literally could not believe his luck. Knock Out was going to kill him, and it was going to be worth it.
Maybe he could hang his seals on his wall like a trophy?
Megatron spoke up again, trying to keep the giddiness out of his voice. “That is fine. Then I will go easy on you at first . Do you understand?” Still very unsure, Starscream still rolled his optics and sighed. “Alright, fine, I do.”
Good. It was best that he consented.
Though even if he said no, that wasn’t going to change the outcome anyways.
Megatron would’ve fragged him even if he said no.
.•*•.
They had soon enough long forgone their modesty, groping each other shamelessly as their glossas intertwined with the other’s in a searing kiss. Starscream was all but thrown onto Megatron’s throne, large servos prying his legs apart and propping them on the armrests of the chair.
Starscream was very much enjoying this, if his heavy pants and long groans were any indication. Megatron dropped in between his legs and let out a hot puff of air onto his panel. Starscream whimpered pathetically and his panel snapped open, revealing a plump, smooth, and undeniably wet light grey valve with a gorgeous little red anterior node that blinked lazily with arousal.
Megatron decided to look up at the normally cocky and smug seeker and his expression was simply delectable .
His glaring red eyes were lidded, fluttering with pleasure every once in a while. His face was flushed a bright blue with equal parts arousal and embarrassment. His kiss-bitten lips were parted, letting out soft pants and moans as he squirmed his seat. His talons had a death grip on the armrests, clenching tightly enough that it may have even dented.
When Starscream made eye contact with the warlord he looked away, somehow flushing even deeper. Megatron grinned smugly.
He wanted to flustered the prideful seeker even more.
“Your slutty valve is so eager.. it’s dripping.” Megatron purred. Two large, sharp digits slithered down to his valve, rubbing in between the light grey folds to gather the dripping fluids before spreading apart, giving Megatron a clear view of his clenching hole. Upon contact with the valve, the mech let out a sharp gasp and tried to arch away from the touch, though lubricants spurted over the warlord’s digits. Starscream snarled nonetheless. “How.. how dare you call me that?! I’m.. mmph.. I’m not..!”
Megatron let out a dark chuckle. “You can complain all you want, Starscream, but it doesn’t change the fact that you’re moaning like a piece of shareware when I’ve barely touched you.” Starscream glared at the warlord and opened his mouth to retort before it faded away into a sharp whine when Megatron put that devilish glossa on his pulsing valve.
He simply explored the outside of the valve, running over his cunt, between the soaking folds of his valve, and sweeping over the madly blinking node all the while ignoring Starscream’s whines. “Ah.. ah.. mm..” The seeker gripped the throne even tighter. He let out an embarrassingly high moan when his glossa swept over his node once more. “Ah! Slag it, Megatron! Stop.. ah! Stop teasing me!” He snarled though it trailed off into another moan.
Megatron laughed, the vibrations only serving to stimulate his valve even more. He pulled away with only a string of lubricant connecting his denta to his soaking valve and smirked at him. “Hmm.. I don’t think I will. You’re not exactly giving me any reason to stop, considering your moaning so prettily for me.” Starscream growled in anger at his response.
Megatron remained unfazed however and continued on. “Though.. there is one thing you could do to make me stop..”
Starscream scowled. “Tell me already!”
Megatron grinned evilly at him. “Beg.”
Starscream froze and his face contorted to shock. “Excuse me?”
Megatron, still grinning, parroted, “I want you to beg me.” At the second in command’s furious expression, he decided to add more fuel to the fire and added, “I want you to beg me to put my glossa in you. I want you to beg me to put my digits in you. I want you to beg me to put my spike in your whore valve, and when I’m done with turning you into a crying, sputtering mess leaking my transfluid from your gaping valve, I want to leave you begging me for one more round .” Starscream growled dangerously at this, his optics glinting with poorly concealed rage. “Like Pit I’ll ever bow to you of all mechs.” He hissed.
Megatron gave him a cruel smirk in return. “If not then I guess I won’t even frag you at all..” His digits left the folds of his valve and the warlord had never seen Starscream look so distressed before. “WAIT-!” He clutched his servo desperately. “Okay. I’ll do it but please.. don’t leave.” Starscream looked like he swallowed a bitter energon cube.
The warlord sneered at him. “You truly are pathetic, Starscream. So desperate for a fragging that you’d cry and beg just for my fingers in your valve. Disgusting. ” He snarled and Starscream visibly shivered, the blush on his face glowing even brighter. Megatron made an interested rumble at that. Did he like being degraded by him?
Oh well, no need to dwell on it now.
Megatron grinned fiercely at Starscream. “Go ahead then,” He sneered. “Beg.”
Starscream looked like he wanted to shrivel up and die at that moment, face burning a fierce blue and biting his bottom derma anxiously. Megatron was surprised that it aroused him. “P-Please..” He whispered, barely louder than a breath, his optics squeezed shut. “Please just..” His voice went quiet, and Megatron couldn’t even hear what he said. His pride was probably keeping him from actually saying the words.
Annoyed, the warlord jammed the thumb of his servo onto his blinking node. He swirled the nub around and rubbed it, as if coaxing Starscream to speak louder. The seeker arched off the throne with a sharp cry that ended in a sob when Megatron rubbed faster. His valve was drenched , lubricant now actively gushing out of his hole in pure pleasure and arousal.
One of Starscream’s legs kicked involuntarily and Megatron responded by gripping the outer thigh and spreading it wider over his throne before lurching forward and sinking his dentae into the metal. The metal creaked ominously as he made dent upon dent on his thigh, each closer to his valve than the last. Starscream moaned pitifully as he lurched off the throne, crying out again when his thumb rolled over his node harshly. “My liege..!” He damn near sobbed, talons now gripping onto Megatron’s shoulders dangerously. “Please!”
Megatron smirked into the metal and then licked a long stripe over the edges of his valve. He licked his lips, tasting the slightly salty lubricant. “Please what? ” His claws gripped his plush thigh so roughly it dented under his strength. Starscream whimpered in pain. “Speak louder, Starscream.”
“FUCK! Please frag me. Please frag my whore valve. I need you in me. I need it so bad. Please my liege. Please I’ll do anything for it. Pleasepleaseplease-“
With a single, swift and dignified motion, Megatron plunged two digits into his valve. Starscream howled in pleasure.
The warlord took his time to explore his valve, making sure to find any sweet spots in there to make him writhe and whine.
It was pathetically easy to turn the normally snappy and proud seeker into a babbling mess. If this was all it took to keep him so pliant, he would have done this a long time ago.
His valve was greedily sucking in his digits the deeper it went, getting wetter and wetter to the point that Megatron figured that he probably didn’t need to get lube. He spread and pressed into the nodes as he continued onwards, drinking in the surprised squeals and gasps in pleasure from his second in command.
Then he finally hit a barrier when his digits were almost halfway in and Starscream shuddered; his seals.
Megatron grinned evilly.
He carefully unsheathed his sharp talons from where they were hidden in a little compartment in his digits and carefully poked a hole in the side of the seal then began to move his digits around it, cutting it.
Starscream must’ve realized what he was doing because his expression went from confused to mortified as Megatron pulled out the slightly transparent plastic seal from his valve. “You.. you..” His optics bulged out of his sockets as he went blue from what was either embarrassment, arousal, or anger.
Probably anger.
“What?” He drawled, giving him a sly smirk. “I just think this would be a fine decoration on my wall. A message to all the Decepticons and any fool who dares enter this ship to tell them who owns you.”
Starscream sneered at him despite his blushing, turning away from him. “You must be more foolish than I thought if you truly believe that anyone could own me .” He snapped arrogantly. Megatron decided not to humor this argument any further and decided to continue probing deeper into his valve, grinning when his walls cycled down on his digits and when Starscream let out a loud cry of surprise and ecstasy.
He added two more fingers, making Starscream writhe uncomfortably from the stretch and making Megatron scowl. “Quit your squirming, this is necessary if you can ever hope to take me.” He snarled. Starscream glared fiercely at him in annoyance. “Well excuse me for being so much smaller compared to you! And this is my first time doing stuff like this, so don’t be such an aft!” He snapped back.
Megatron scowled even deeper and decided to harshly jab his fingers inside his valve, making Starscream yelp in pain. “What the frag was that?!” He yelled angrily.
The warlord only grinned at him. “Just a reminder who’s in control here. Spoiler alert: it’s not you.”
“Frag you.” The seeker spat.
“No, I’m pretty sure I’m the one fragging you right now. Or at least I’m about to.”
“‘Going gentle on me’ my aft .”
“Are you deaf? I said ‘ at first ’. I didn’t say I was going to be gentle on you the whole time.”
“When were you ever gentle on me?! The moment we started you practically threw me on your throne!”
“Stop complaining, you liked it.”
While they were bickering, Megatron had been able slip his thumb inside so he had his entire servo inside him valve now. Megatron let it sit there for a moment before he had enough of Starscream’s nagging and began to pull back his hand.
Whatever Starscream was about to say died in his mouth in favor of a long and drawn-out moan, his legs quivering and eyes wide. Lubricant dribbled out of his valve and pooled around his aft in an alarmingly fast rate, showing how turned on he was despite his sneering words.
Megatron grinned toothily, curled his servo into a fist, and then pushed back in agonizingly slow, pressing against the nodes aligning his valve and bathing Starscream in strut-melting pleasure. The seeker let out an embarrassingly high whine, thighs twitching as if he wanted to cross them over his master’s arm so he could keep him locked there.
He was so slagging charged right now, his vents were working overtime to futilely cool down his frame. When Megatron’s knuckles ran over a certain bump deep in his valve, Starscream melted , sagging into the chair and moaning loudly in the face of such intense pleasure. “Frag.. fragging Pit ..” He panted.
Megatron gave him a smug look. “Look at you, all pliant and disgustingly soft after a little bit of fisting.” He cooed mockingly. Starscream tried his best to glare at him but when his knuckles pressed into his sweet spot again it all faded away into a look of pleasure. “Mmm…!” Was all he could reply with, lifting his hips higher so he could take it deeper inside him..
Megatron’s engines revved hard. Damn it, he was seriously getting turned on by this. He hated to admit it, but Knock Out was a damn genius for suggesting this competition. He would have never thought that Starscream of all mechs could’ve turned out to be attractive when he’s not running his stupid mouth and instead moaning like a bitch while his valve squelched around his hand.
He would not wait anymore. He needed to take him, now .
When Megatron’s fist left his valve so suddenly, Starscream was jolted out of his lustful haze abruptly. Confused and upset, he tried to sit up to give the warlord a piece of his mind before a mechanical click of a panel pulling away grabbed his attention.
And then the hefty weight of a spike fell upon his thigh.
Starscream felt immediate regret from accepting Megatron’s offer the moment he laid his eyes on that monster of a spike. It was literally the size of his thigh.
He looked up at Megatron, fear and concern on his face, eyes darting from the warlord to his spike that was currently resting on his leg. “Y-You can’t be serious, right? It’s way too big for me! It won’t fit!” He panicked.
“With all the stretching I did? It’ll fit and even if it won’t..” Megatron leaned in, eyes glinting with dark arousal. “I’ll make it fit. ”
“You..!” Starscream tried, but there was nothing he could do to rebut what he said. Megatron frowned at him. “Backing out now?”
The seeker scowled. “Of course not! I’m not a coward!”
Megatron stared long and hard at him for a moment before he shrugged and lined up the head of his spike to Starscream’s dripping valve. “Alright but remember, you wanted this.”
And he slid in.
