Chapter Text
Megatron was agitated.
Was that the right word? There was a slight twitch to his digits. His pedes couldn’t stay still under the table during the command meeting. He kept wanting to shift and lean on his servo and glare at whatever mech was speaking until they stopped.
But there was one mech he doggedly ignored, despite him speaking with a goading tone and light insubordination.
How had it come to this? They had fragged twice so far, and it had been quick and unsatisfying and they had both regretted it and said they wouldn’t do it again. But now, all Megatron could think about was holding the seeker down and then fragging him until they both came in guilty overload-
He was supposed to hate him, damn it. He wanted to hate him. Everything about him should repulse him: he was a coward, he was disloyal, he was whiny, he was far too intelligent, and he constantly tried to overthrow him! Megatron knew there was such a thing as hate-fragging, but that didn't explain how the seeker invaded his thoughts and some of them were practically domestic in nature-
Oh. Soundwave had asked him a question.
“Whatever you think is best, Soundwave. Are we done?”
Soundwave hesitated only a moment longer and then nodded. “Yes, lord Megatron, we have concluded.”
“Good. Dismissed,” he said with a growl. He stood from his seat and stalked out the door.
He needed to go punch something and given that the Autobots were not currently in front of him, he decided to go down to the training room and destroy some training dummies.
He could feel the build-up of tension in his lines, his struts, his joints. He just needed to get it out of his system and get him out of his system-
“It’s only been a week,” came the amused, raspy voice from behind him.
Megatron whirled on his pedes, anger dripping from his field. Starscream was leaning against the doorway to the training room, his blue arms crossed in front of his yellow cockpit as if didn’t have a care in the world. And to Megatron's irritation, Starscream didn’t flinch at Megatron's seething face. “You really shouldn’t be around me right now.”
Starscream arched an optic-ridge. “Concern for my well-being? I’m touched.”
“I’m serious,” Megatron snarled. “No games. I will rip your pretty little helm off your shoulders at the slightest provocation.”
Starscream’s wings twitched, as if the prospect was enticing. “You think my helm is pretty?”
Megatron groaned and turned away. “I don’t have the patience nor the inclination to deal with you right now.”
“Or perhaps, I am exactly what you need?”
Megatron rounded to tell the seeker to frag off, but Starscream had rearranged himself so that his servos were behind him and his chin was up in a defiant grin. This pushed out his chest in an alluring way. Standing like that, his weapons behind him, he was defenseless and at Megatron’s mercy.
And his field was… an invitation.
Megatron was quickly losing this fight. “I don’t know why you think it will be different from any other time we’ve done this.”
Starscream leaned forward more, away from the wall, showing off his curves and angles. “I’m a glutton for punishment.”
Megatron growled and stepped closer to him. “This… this can’t happen again. This is the last time.”
“Naturally,” Starscream said, his wings twitching again. “Won’t even dream of suggesting it again.”
Megatron stepped closer so that he was looming over Starscream. He could feel the warmth coming off his frame and wanted to… touch him. When did it go from wanting to punch the smirk off his face to wanting to make him moan in pleasure?
And… there was something else. Something deeper in his processor, something old, and something he had thought was dormant. But his fragging coding kept making itself known and every time he fragged the same seeker, his coding kept thinking he was mate material-
Megatron punched the wall next to Starscream’s helm and leaned in closer, their noses almost touching. “Why do you keep doing this?”
Starscream understood what he was asking even though Megatron didn’t elaborate. “I wish I could say you were an excellent fuck, but to be honest? I just like seeing you come undone when you overload.” He kept his servos behind him but lightly exvented out his nose so that Megatron would feel the warmth breath mingle with his own.
Earth slang. Cute. Juvenile. Why did his frame want to mate this creature before him?
Starscream leaned forward and kissed him, tasting like danger and lust.
Megatron’s black servos reached out for his waist, intending to bruise a little if he could. The pads of his digits dug into his hip plating and Starscream hissed a little in slight protest, but otherwise kept kissing him and- surprisingly- keeping his servos behind his back.
“Your hab or mine,” Megatron said, pulling back.
“You nearly broke the desk in mine last time; yours will suffice,” Starscream murmured. “Since it is to be our last coupling.”
Something in his voice made Megatron think he knew it wouldn’t be their last time either.
He exvented and pulled away walking quickly to his quarters. He didn’t need to look behind him to know that Starscream was following at a “safe distance.”
His panels were resonating with lust. He was now resigned to the fact that having tasted the seeker, he now was addicted and was going to need an outlet for the frustration regularly. Starscream was far too smug, but Megatron thought that he too might be similarly addicted. He’d have to find out.
When he reached his quarters, he opened the door and stalked in, going straight for his high-grade.
Starscream sauntered in behind him and eyed his quarters. Megatron suddenly feared that this was actually an assassination attempt and not a dangerous liaison for their interface equipment. As if sensing his unease, Starscream threw him a sneer. "Liquid courage, Megatron?"
"It lowers my inhibitions and standards."
Starscream groused, throwing his nose in the air. "You are lucky I'm willing to put up with your substandard and outmoded equipment."
Megatron angrily threw back half a cube of aged high-grade of Tarnish vintage. He grimaced as it burned down his intake but quickly warmed his systems. He could feel the light buzz of overcharge soothe his frustration. "Lucky? Or cursed?"
Starscream flinched, which was interesting- as if he had feelings that could be hurt. "Why can't you just be…" he started, angrily, but then stopped. He pretended that he had never started that sentence and sat at the edge of the berth as if testing its firmness.
Megatron took a smaller sip of his high-grade this time and watched as Starscream crossed his legs absentmindedly. It was unfortunate for Megatron that his second in command was naturally elegant when he didn't realize he was being observed. He was looking around the room, observing Megatron’s private quarters more with curiosity than the disdain Megatron had expected. His optics settled on some of Megatron’s old battle swords from the arena that were hanging on a far wall; old things, antiques at this point and hardly polished to their best form. Starscream’s optics took on a strange wistfulness as they settled there and then he flicked his optics back to Megatron quickly and then to the ground.
Deciding to get this over with,, Megatron set his drink down and closed the distance between them. He settled a servo on Starscream’s shoulder to push him down to lay back against the berth. He pulled apart his thighs and prepared to brace himself on Starscream's hips.
Starscream gave him an odd look of regret and Megatron nearly growled. “Why do you suddenly seem unwilling to do this?”
Starscream blanched. “No, I’m willing- I just. Maybe, we can try doing it differently this time?”
Megatron’s optics narrowed. “Different… how?” He better not want to spike him.
Starscream quickly tried to find his voice or his words. “...slower?”
Megatron hesitated in his reply because he had been thinking the same thing, but his pride couldn’t quite admit he… enjoyed this. But he was stubborn, and his vocalizer said, “I thought we both wanted this done and over as soon as possible.”
Starscream was far too clever though and had guessed his actual thoughts. “Why don’t we try it my way for once and see if it changes… our minds?” He had a small smirk now at the corner of his lips.
Megatron merely grunted in reply and Starscream’s smirk only widened. He leaned down, looming over the smaller mech and enveloping him with his field of want. Their faces were tantalizingly close now, and Megatron had the annoying desire to be tender with him, to cup the side of his helm or to hold him by the small of the back. He held himself back because he couldn’t stomach the derisive look he thought he would get in reply.
Instead, he ran a servo down the front of Starscream’s cockpit, enjoying the smooth texture of the warm glass against the pads of his digits. Despite Starscream’s abrasive personality, Starscream was a well-built mech and Megatron delighted in the feel of his polished plating. Starscream seemed to enjoy the gentle attention if the slight hitching of his vents was anything to go by.
This… was different. Their interface sessions so far had been quick and fevered, and the overloads had been… sufficient but not great either. But the building charge across his lines promised of something more now, and he… couldn’t stop himself from getting excited.
Starscream hesitantly brought a delicate blue servo up to Megatron’s broad chest, running along the seams of his collar plating. Megatron thought there might have been something reverent in his touches, but he couldn’t exactly be sure.
Derisive looks and comments be damned, Megatron leaned in and began to kiss Starscream’s neck.
Starscream stiffened at first, likely unsure about Megatron’s intentions, but then felt what he was doing and… for lack of a better term, melted. Starscream laced his servos behind Megatron’s neck, encouraging him to continue, even as he pulled him down and on top of him onto the berth.
There was a small scrape of Starscream’s cockpit against Megatron’s abdomen, and Megatron had to brace himself on the berth with his knees lest he crush Starscream beneath him, but otherwise he could not complain. Starscream’s neck cabling actually tasted… good. He began to lick and suck the sensitive cables he found there, and Starscream made a little noise of appreciation. Encouraged, Megatron pushed harder against the neck and began to trace his servo down Starscream’s cockpit to rest on his belly.
“Who knew you could be so gentle?” Starscream murmured. It wasn’t… scornful like Megatron had expected. His voice was husky and… in awe. Megatron’s spike was eagerly asking for release beneath his panels.
Primus, did he want to take him.
Megatron reached down and began to touch the outside of Starscream’s interface panels, and Starscream retracted them without additional requests. “Who knew you could be so obedient?” he said into Starscream’s neck with a smile. He retracted his own interface panels and allowed his spike to pressurize as it poked into Starscream’s inner thigh.
Starscream tensed a little in anticipation. His optics were bright, and he looked younger than he was in his eagerness. Megatron was surprised at how… attractive he looked.
“What?” Starscream asked, his brow furrowing.
Megatron collected himself and instead dipped his hips so that his spike dragged across Starscream’s exposed valve. He reached down and carefully touched Starscream’s anterior node, rubbing it with his thumb. Starscream seemed to appreciate the gentleness of all things, so he continued to provide it. Megatron noticed the valve he touched was wet with lubricant and he smiled as his spike rubbed tantalizingly at the rim, asking for permission to enter. Starscream hummed and nodded, shuttering his optics and stretching out beneath him.
Megatron then grabbed his spike, lined it up, and slowly sank into the eager wet heat of the valve.
Starscream gasped, tensing around the spike. He was tight and Megatron groaned as he began to slowly push in, taking his time. Starscream’s wings flared out more on the berth behind him as he tried to find purchase on Megatron’s back. He whispered, “Megatron,” like a prayer, and Megatron growled in response he pushed in deeper. Satisfied at the depth he had reaching in the valve, he rocked backwards and then pushing forwards again, exventing at the sensations across his spike.
There was a ping from an old program that Megatron didn’t immediately recognize. He dismissed the notification without reading it.
Starscream was right, he admitted begrudgingly. Slower was better. Starscream began to make noises of pleasure that started soft and then crescendoed louder and more desperate as Megatron continued. Their vents were labored as he pounded into the valve, and Starscream lifted his hips to meet him.
He was beautiful, frankly. Starscream’s waspish waist that led to attractive hip plating was perfect to hold as he railed the seeker into the berth. His darker faceplate made his red optics stand out even as they were dimmed in pleasure. His thruster pedes were beautifully curved and Megatron admired them even as they wrapped around his waist and dug into his back.
He wondered what Starscream' spark looked like. He would probably make a great carrier.
Another ping. He ignored it.
Starscream was getting close. He tightened his legs around Megatron’s hips, giving him the ability for less powerful thrusts, but they were deeper and he dragged across the sensitive nodes inside of him. It was tortuous and wonderful to be this deep inside him and the noises of rapturous want that bubbled from Starscream's lips nearly drove him mad.
He started kissing him on the mouth, and Starscream moaned in need.
This time, the ping was accompanied by an increase in pressure as his spike swelled. He and Starscream both gasped at the same time at the sudden tightness. Megatron then overloaded with an escaped moan, leaning his forehead to Starscream’s. He gave a few more thrusts and was surprised when Starscream gave a moaned shout, and his frame trembled.
He… had overloaded. Come to think about it, Starscream hadn’t done this during their previous interface sessions.
Starscream went a little limp as he tried to catch his vents. Megatron just watched him, his optics wide. He… he was beautiful in his undone state, and he too seemed surprised by the force and pleasure of his orgasm. Megatron wanted to lean down and kiss him again and was about to do so when Starscream placed a finger on his lips.
“I need a minute,” he said quietly with a small smile. “What is that, a knot mod?”
Even breathless, Starscream exuded sexiness, and Megatron wanted to keep going. His spike twitched inside Starscream and they both flinched at being overly sensitive post-overload.
“I…” he started, but his voice failed him as the question hit him. “A knot mod,” he repeated dumbly.
Starscream chuckled a little. “You alive, old mech? You got a little bigger than I expected suddenly. Generally, it’s better to talk about these kinds of mods ahead of time, but I don’t exactly mind.” He stretched languidly under Megatron’s confused gaze.
Megatron’s processor was hazy. He… did have a knot mod from a really old program, but it had been long dormant. It wasn’t supposed to activate unless he manually disabled the hold.
He tried to pull his spike out of Starscream, but they both hissed as the knot couldn’t quite get past the tight callipers of Starscream’s valve.
“Deactivate it,” Starscream said, with a little growl.
Megatron nodded and attempted to find the right coding. But to his increasing despair there was no shutoff command. No… retract command.
“It… has a cooldown. Just give it a few minutes,” he lied.
Starscream nodded tiredly. “You seemed more blissed out than usual,” he said with a smirk. He hesitantly lifted up a servo to touch the side of Megatron’s helm. It was… a very intimate gesture.
He supposed it could be allowed given that he was still fully hilted inside Starscream’s valve.
“I have to admit going slow… worked,” he murmured back. “It felt… better.”
“Told you,” Starscream chided. Megatron leaned into the servo’s touch and saw Starscream’s optics soften a little. “Maybe there are other things you could listen to me about,” he said mischievously.
Megatron’s optics blazed. “If you are hoping to get special favors just because you let me spike you-”
“Relax,” Starscream interrupted, rolling his optics. “The spiking is worth it in its own right.” He stretched his arms behind him. Megatron watched appreciatively.
“I thought my equipment was ‘substandard and outmoded,’” he quoted.
“You need to learn to appreciate nuance, Megatron,” Starscream replied. He looked far too pleased with himself. “Now. Not that I mind having your spike deep inside me, but I have a patrol to get to.”
Megatron grimaced as he slowly tried to pull his spike out. Yet again, he could not.
“Megatron. Deactivate the knot,” Starscream said, a little irritated.
Megatron gave him a furious look which did not dissuade Starscream from looking incensed right back. “Megatron.”
“I… can’t,” he said, finally.
