Looking at him, it was too painful, so he didn’t bother.

But no matter how hard he tried, the sounds would reach his audials & echo around in his mind in a building chorus of discord. Each creak in the mech’s joints, every shuffle of the other’s pedes across the cold, damp floor of the cave along with the recurrent echoes of twiddling digits only served to drive him slowly insane. The varied mix of ambient noises performed poorly in filling the void of awkward silence between the two mechs as the moments stretched on with no way of telling how much time had actually passed, since the only source of light in the cave the two found themselves in to be filled with natural flora & fauna that were giving off their own sources of bioluminescent light as they fought their own battle against the suffocating darkness that they occupied. There was no moonlight, no sun, no way of telling how long he’d sat in the darkness with the mech he’d once called his lover, his companion, his other half.

He’d rather not dwell on such titles, though.

The silence the two bots occupied left too much to think about, too much to ponder as the silence stretched on for what seemed like an eternity. They had both fallen down here possibly hours ago, but there was no way for either of them to know for sure. Eventually, crimson optics slid over to the figure they so desperately yearned to avoid once their owner's patience had run thin, a burning feeling taking hold of the mech's spark & filling up the chamber within with what felt like acid as it bubbled & churned within the space there, slowly eating away anything other than hatred. An irritated processor reasoned he needed something else to distract him from the scrambled mess of thoughts that occupied his own mind, since the train of thought of attempting to judge how long he’d been stuck down here was getting him nowhere, leading to the mech’s frame in a balance of feeling numb & heavy all the same. Better to have the familiar rush of venom & hatred filling his spark than nothing at all, he reasoned.

But it wasn’t hatred, not truly. He didn’t bother to think about it, filing the thought away into the back of his mind as he’d done so many times before, leaving the thought likely to never be addressed again as his processor wandered.

He ignored the thought & pressed on with as much fortitude as he could muster, crimson optics focusing & adjusting with a series of gentle clicks & whirrs as pieces of the mech’s internal structure adjusted to the command & his thoughts within. It helped to distract his processor from the other problem at hand, the lurching feeling of his presently injured left arm pinging his processor for attention, a series of sparks flying away from his form as it did so. He’d injured himself in the fall into the cave, but his processor opted to shuffle the thought away & file it for later just like before as it focused on what it considered to be the priority at hand.

The silver mech sat with only himself for company upon a jagged boulder that had just enough room for one form to rest on, leaving no room for further company to join him, even if his present were to be allowed to do so in the first place. Yet with heated optics now set on what they loathed so deeply, the large mech found his form lurching forward until his forearms rested atop his tibulens, shuffling his weight so his left arm was allowed to remain mostly slack so he could further ignore the sense of pain traveling through the appendage, & leaving him in enough comfortably to speak.

“When are you going to look at me, Prime?”

A thick layer of venom dripped from the mech’s dermas then as the words left his intake, his voice crackling in the silence that still dared to hang between them after his words hung heavy over the other mech's helm. Crimson optics watched the mech before them like a predator stalking its prey, waiting for any sign of movement, of life, of anything . But all they were met with was the other mech’s frame sitting almost eerily still, along with azure optics that continued to refuse to meet with his own & the other's battle mask tightly shut across the mech's faceplate. Instead, the weight of his gaze & the angle of acerbity in his tone somehow managed to at least elicit a verbal response from the mech, managing to quell the burning feeling in his spark, albeit barely & for only a nanosecond at the very best. The Prime's words came out in a slow drawl of patience & quiet, as if he was afraid to spook the other bot with the deep resonance of his own voice. 

“...We're wasting time. I’m not going to pretend to indulge you in your delusions when we both know our true goal. We should be working together to find a way out of here, you know that, D–”

A loud bang reverberated through the space then as a certain silver mech slammed his pede down onto the cave floor in protest to the Prime's speech, the shrill sound echoing off the walls of the cave until the noise eventually settled & faded into nothingness, just like the Prime’s voice after he had cut himself off from putting sound to a name that, in some minds, should never be spoken aloud again. Crimson optics were forced to watch as the Prime’s neck plating appeared to almost swallow the name back down his intake & into his voice box respectively, possibly attempting to bury the sound as deeply within him as he could before the other mech spoke in reply.

“Say it, Prime. Say my name. My real name. ” The warlord paused then before he continued, clear disdain & vile in his tone as he did so. “I won't stop until you do.”

A soft rumble of a reply came from the other mech once he seemed to eventually find the strength within him to reply, his light tone contrasting his form as it weighed heavy then on his protoform as he sat on his own boulder across the room, optics trained to the floor as he refused to lift them in response to the other mech’s outburst.

“No.”

There was a finality to the word that stirred something within the silver mech as he took it in. Heavy pedes shuffled until the form above them rose as the voice within the frame they held up did the same, leading to yet another demand that echoed off of the cave walls in a more severe & abrupt outburst. It found itself matched with the Prime's own spoken finality, & one mech was simply not going to yield. Not this time. 

“SAY IT!”

Finally, a small wave of satisfaction reached his spark as azure optics finally left the cave floor below, leading to the other mech’s gaze finally settling into his own.

He didn’t know what he expected.

Optimus’s gaze lingered heavily with the weight of a thousand unspoken words that would likely never find the chance to be put to sound. The thought almost began to haunt the warlord before he took in more of the Prime. The mech looked exhausted, the realization dawning on him as his spark twinged within his chassis & refused to settle. The light of the other mech’s optics appeared dimmer than the last time he’d managed to catch his gaze so many cycles ago as the light around the edges of his optics flickered with a diminishing charge that had left the fire within them long ago. Megatron found himself being unable to shake the uneasy feeling in his spark as he further analyzed such tired optics. They didn’t resemble what he’d come to know after so many cycles in his early years as a miner. Of course they didn’t, he resigned to himself with a bitter pang of his spark resonating within his chassis that he deliberately opted to ignore. A beat of silence passed between the two bots then until the Prime's demeanor seemingly fell flat once again, his tone slipping into a whisper as his throat tightened, seemingly holding back a response until the words left his dermas in a strained & hushed reply.

“...You want to hear your name, Megatron?”

Megatron felt his form twitch with an unrelenting wave of something he couldn’t quite name as azure optics seemed to dim further & the feeling within his spark seemed to surge a tinge stronger as crimson optics searched the Prime’s own after hearing his name finally be put to sound through a familiar voice that send a reluctant wave of want through his form. Searching & yearning for what, he wasn’t sure. But each comment & retort seemed to breathe a speck of life back into the Prime, leaving his spark to be led along by an unknown force as he began to chase that fleeting high. Rough digits twitched along the sides of Megatron’s form as he tracked the Prime’s gaze, the other’s optics now refusing to leave his form in an intense battle of wits & internal dialogue. An electric shock of want rushed through him again, this time down his back strut with a newfound intensity as he felt himself slowly begin to be dissected under the Prime’s gaze as the moment stretched on for what seemed like forever. It left the leader of the Decepticons wanting more, though in a moment of resignation did he hold himself back from chasing such a naive desire in an attempt to regain a sliver of control over himself, choosing instead to simply relish in the feeling & to let his thoughts wander for a brief moment.

For a moment, he was the one being dissected, to be scrutinized under the other bots’ gaze, to be watched with a predatory veil over the other mech’s gaze as he realized that one sudden movement could spell the end of his being, here & now. Though a weighted wave of disappointment washed over Megatron’s form as the energy surrounding the Prime dissipated as quickly as it had arrived a few moments later, the energy surrounding the other bot beginning to settle into something more mild, leaving the other’s gaze to soften slightly as the energy within the mech’s optics began to dim & his form shifted until he was facing slightly away from the other bot, though his gaze still lingered over Megatron’s now equally dimmed form as the moment dragged on.

Rough digits found themselves tightly clenched together as that all-too-familiar feeling rushed into Megatron’s spark, though his processor quickly shifted to find a solution this time around. If aggression wasn’t working, he’d have to switch gears into something that would really push the Prime’s buttons & grind his gears. Something more… personal. But before the words could leave his dermas, the Prime’s rough voice rumbled from his voice box in a delayed continuation of his previous question, leading to a pause in Megatron’s thoughts as he was forced to listen to the other mech’s speech.

“...I don’t know what you want me to say, Megatron,” There was a pause then, as if speaking Megatron’s name was almost painful before Optimus continued once more in a hushed tone, optics still averted from the subject of his speech. “Once we leave this cave, we’ll be fighting. Again, and again, until what? Until there’s nothing left?”

A heavy set azure & ruby frame rose from its place on the boulder it had rested on then, the mech the form belonged to rising with a sense of newfound grace as he appeared to finally find something within himself to face the other mech. As crimson optics began to feverishly take in the other’s body language and meaning to his words, the Prime continued. His frame remained tense, as if expecting something to occur once he’d finished his words.

“The Quintessons are still out there,” Optimus gestured with a swing of his servo, gesturing above to where the surface laid above them, closed off due to the cave-in that had led to their current predicament. “And yet, we find ourselves fighting a conflict that seems to have no end in sight.” Azure optics narrowed then as Optimus took a step closer towards Megatron, but he wouldn’t falter. Not in the face of a Prime. Not in front of…

For a moment, he found himself lost in his thoughts, as he often found himself doing as of late in the presence of said mech, though what came out of the Prime’s voice next sent a violent shock through his system all the way from his helm to his pedes as Optimus’s voice shifted into more of a plea than a lecture.

“Why, Megatron? We defeated Sen–”

A violent jolt reverberated through Megatron’s form then, the mere mention of the mech that started it all causing the tension in the silver mech’s form to increase tenfold, leading to Optimus’s body language attempting to convey a sense of cordiality as he attempted to ease the energy surrounding them both with open servos that faltered slightly once Megatron began to speak.

“I defeated Sentinel. After you did nothing but stand in my way, ” Megatron growled, his voice coming out in a low timber & dripping with more venom as he continued, pedes shuffling until he was a few more feet closer towards his foe. It dawned on him then in a moment of pure clarity as he found himself a mere few feet from the Prime & felt himself further entrenched in the pull of the other’s field. He would get what he wanted out of the Prime tonight if it was the last thing he did, he’d make sure of it.

Before Megatron could continue, another pregnant pause found itself lingering between the two mechs then, its weight rapidly descending like gravity upon the room as an unspoken retort lingered on Optimus’s faceplate that found its voice through his aching optics. Even though his dermas remained hidden behind his battle mask, he could see it plastered all over what he could see of the other bot's faceplate in a brilliant display of mixed emotions.

“You did. After you went through me .”

The Prime’s hesitance only served to fuel that twisting feeling within his spark that churned every time crimson optics locked with azure ones, determined to deflect any attempts at congeniality that were sent their way. Yet what flashed through the Prime’s optics was something Megatron hadn’t seen up until now, & before he had enough time to fully process it the other mech’s words were verbalized in a quick retort.

“I helped everyone see the truth without the need for bloodshed. And yet, that’s all you strove for that day. Had you only listened to reason, we wouldn’t be in our current predicament. Yet you chose chaos & let yourself be consumed by despair, & look what’s become of it. Us, down here, while the Quintessons do Primus-knows-what to both our troops & Cybertron continues to fight one war that isn’t even necessary!”

Something in the air shifted then as Optimus’s form shifted towards Megatron’s own, leaving the latter to react only as a spectator as the other’s rant continued. He fought back the urge to smirk as he began to witness the Prime’s unraveling in real time. Cycles of pent-up frustration & grievances being thrown at him with the utmost vitriol as the other’s placid facade began to crumble, & he found himself reveling in the attention as the tension in the other’s form rose.

“We could’ve built the future together,” Optimus pleaded, his voice almost cracking from the weight of his soul bearing itself true through the chorus of his words as his battle mask shifted, his form beginning to settle from his previous outburst. Some of the satisfaction of watching the Prime become riled up from what was likely a release of cycles of masked emotions began to dissipate in Megatron’s spark as a stray thought managed to sneak its way into the back of his processor, leaving him feeling perturbed & distracted just enough to not fully decipher what it meant before what happened next. 

This is what he wanted, isn’t it…?

As the thought bounced around his processor, a sudden chill entered the room that caused the Prime to stop in his tracks, both verbally & physically as the atmosphere abruptly shifted & Megatron took it as an opportunity to shift his form ever so closer to the other mech so they were only a few heads apart. He watched as the other mech’s form tensed, perhaps out of habit, & for some reason it sent a cold shiver down his back strut as he shifted himself closer to the Prime. Now he was here, in his space, & he could feel as the other’s field shifted & hummed with increasingly more powerful waves of energy as the moment lingered on. Here, he could get up close & personal & examine every bit of him that made him the noble Prime almost everyone in Iacon saw him as. Their city’s savior, shining & new. For a moment, his processor lingered on the realization that the Prime was even letting him into his space like this, the thought sending a nauseating feeling down to his stomach as the thought swirled down & around his head before completing the lap in one nauseating loop.

Megatron’s processor began swirling into the same suffocating loop of thoughts as crimson optics wandered across the other’s form, lingering on various spots across the other mech’s body before his right servo began to twitch, heavy digits reaching out in a gentle reach for a fraction of a second before clamping back up into a tight fist next to his side. Optimus’s optics shifted then down to where his servo stayed next to his form as he tried to hide his previous gesture, feeling as the other’s azure optics weighed heavy on the body part, as if he was expecting it to come to life once more & continue its previous goal of reaching out towards him. Megatron’s energy field radiated with a feeling that matched the tension in his frame as the feeling oozed into his own energy field surrounding himself, his spark fluttering with a light jump in his chassis as he watched large servos reach from the Prime’s form slowly begin to reach for his own. Optimus’s digits began to reach out almost eerily slowly, & if Megatron were to let himself blink, he could almost swear that the Prime’s digits weren’t moving at all. But his theory was quickly proven to be false as the other’s digits entered his field & an elongated index digit just oh so barely ghosted his frame atop his forearm where the metal met the start of his servo, leaving crimson optics to shoot up to meet azure ones that blazed bright with something Megatron didn’t dare put a name to.

Yet, he almost didn’t have to. Azure optics blazed with a surge of something that could only be described as pure desire, &, if he looked close enough, longing . The sickening feeling that had dropped into his stomach earlier found itself surging back up his intake like acid reflux & thrummed past his spark chamber, leaving Megatron’s faceplate to twist into a look of pure disgust as he felt himself physically & mentally recoil from the sight as he pulled away from Optimus’s touch. Even after all he’d done, to Optimus & Iacon itself, here the Prime was, trying to comfort him & reach out to him in the middle of a lecture that was only the beginning of what he deserved (some would debate). Crimson optics searched the Prime as the other’s expression watched Megatron’s form recede from his touch, momentarily flashing a layer of hurt before settling into something more neutral as azure optics flickered & whirred in a series of quiet whirrs to search once more before the other’s form receded ever so slightly.

The two of them remained close however despite Megatron’s retreat as the silence lingered between them with Optimus’s solemn energy in a quiet battle with Megatron’s own agitated aura, leaving the two bots so wallow in silence before the former decided he’d had enough, & spoke.

“Tell me, Prime, ” The title fell from Megatron’s dermas as if it was a swear, his lower derma almost threatening to quiver before he continued, “If you had the chance to do it again,” He paused, his optics narrowed with precise hostility as he kept his gaze locked with Optimus’s own. “Would you save him again?”

It took a beat then for Optimus to respond, leaving Megatron to watch as the other appeared to almost steel himself to reply to the latter’s inquiry. But it was all a facade, that much was obvious.

Wasn’t it…?

“To save you, ” Optimus corrected with a slight alteration in his tone as he continued, “I would.”

In that moment, a familiar, burning ember flickered to life within Megatron, & he felt himself almost flinch as the feeling nestled itself deep within his form & infected him as it writhed in the space there with sickening familiarity. He’d almost let himself be pulled into something that felt so safe, so nostalgic, & he hated himself for it. He hated his complacency, how easily he crumbled under someone who he currently viewed as his enemy, his main goal keeping him from a Cybertron he wished to form into fruition. A sharp scoff left his intake as the other’s words settled into him & took root next to that ember, only serving to add fuel to the fire as it did so & called back to an instinctive feeling to give in to whatever he was being dragged into. His spark began to search for that familiarity that stood in the form of the mech in front of him, but with an ache that swept through him he knew it wasn’t the same. It never would be. So instead he let himself go, if for just a moment in order to move towards the Prime, using his momentum as he reached out, using his undamaged forearm to place his servo on Optimus’s chest plate & push him towards the cave wall that they both stood in front of.

He was met with surprisingly little resistance as Optimus shuffled his pedes backwards until his back met the wall with a distinct thunk, as if he was expecting such a reaction from the mech in front of him. Another scoff left Megatron’s dermas as a wave of frustration rushed over him as he was met with yet another realization that he was being read like a data pad. Optimus could push him back with a single servo & use his newfound strength to physically challenge Megatron, here & now, that much he’d shown that fateful day in Iacon. The Prime had every opportunity to push back, both figuratively & literally, yet here he was, being willingly maneuvered onto the cave wall with little resistance by the very mech that had betrayed him so deeply.

And that just wouldn’t do, Megatron decided with something new settling in his spark that still managed to serve the ember within. He would get what he wanted tonight, that much he was certain of. He was Megatron, leader of the Decepticons, & he wanted to break the mech before him if it was the last thing he did tonight.

He wanted to break Optimus Prime.

Following his newfound determination was the sensation of the gentle & steady hum of the Matrix nestled within the other mech's chest cavity, the azure light within pulsing in tandem with the same rhythm as the Prime's breathing as he remained pinned against the cave wall. Megatron’s optics narrowed once more & allowed his thoughts to roam further as his digits began to curl & grip at the seams of the mech's chest armor, watching as his own digits carefully maneuvered themselves into any available crevice that they could find as they placed their hold there. For the next few moments the Prime remained almost eerily silent, yet his form screamed silently in a vacuum of the mech's charged aura as Megatron further pressed his digits into the transparent glass upon the Prime's chest, his grip tightening more and more until the clear sound of glass beginning to crack reached Megatron’s audials in distinct succession, the sound building in his audials until a firm grip was planted onto his forearm a few moments later.

Feverish optics flickered up to meet with azure ones that blazed with something new & electrifying, the Prime’s optics ablaze with life once more as his servo retained their firm hold on the silver mech’s forearm. Yet Megatron didn’t falter, opting instead to increase his grip on the glass upon the Prime’s chest, his spark twisting with a sickening satisfaction as the material there began to crumble further under his sheer strength alone. He could tell the mech before him was becoming more & more tense as he continued, the other’s energy field & body language becoming increasingly more agitated as he refused to relent from his task. Optimus responded in turn by using his free servo to place another unsuspecting & firm grip onto Megatron’s injured spare arm that currently laid lame at his side, which still sparked in response to its ongoing state of neglect.

Megatron’s form jolted from the sudden touch, a clear display of surprise flashing across his faceplate from the pain as his sensors sent a series of alerts across his display. He attempted to reprimand such a clear show of weakness by replacing it with that sense of aggression that had become all too familiar in the presence of the mech he’d come to loathe so deeply, his canines in full display as he gritted his denta together & his engine rumbled. His chassis shook from the force alone, & Optimus’s chassis mirrored his own as the moment went on & the tension in the air reached a thickened state. Both mechs refused to yield, yet as the moment lingered, somebot was bound to break.

“Enough, Megatron,” Optimus began, his voice attempting to remain steady as he continued to push back from the other mech’s grip. “End this.”

Meeting the other mech’s gaze, Megatron expected to be met with a matching display of hostility that would mirror his own. After all, the grip on his forearms were anything but gentle. Yet the Prime’s optics betrayed his actions, much to the silver mech’s surprise, azure pools pooling with a startling display of aching sorrow that sent a jolt through Megatron & down his backstrut. He felt his form go numb for a moment after the shock had made its run through his systems, his processor being wiped clean before being replaced with the image of a bot he thought he’d managed to forget. A bot that died as he shot a fusion blast through his torso, leaving the other mangled & beyond recognition before being sent plummeting into the abyss & into Cybertron’s core. A smile that was sent his way from every retort & common tease. A gentle & warm kiss placed on his dermas before settling down to recharge for the night. For a moment he was sent back to the past in those optics, & for another moment he let himself falter as his canine gnawed at his lower derma & a heavy breath escaping those same dermas, one he found himself unaware of even being restrained as it left him.

He found himself reflecting then after the heavy breath left his processor free to wander. Did he regret that fateful day, bringing justice to Cybertron’s oppression, freeing it from a false leader who only served to perpetuate a false narrative? A false lie? Years of obedience & servitude, of dreaming of what could’ve been achieved, all for nothing. He’d got what he wanted, yet every time his thoughts wandered to the Prime, he felt…

Reluctantly, the silver mech relaxed his grip on the Prime’s chassis, albeit barely as he allowed the past to consume him, causing the latter to mirror his now newly relaxed state. Yet a layer of agitation still simmered underneath his calm façade as Megatron’s injured arm sparked & groaned in protest as he pushed aside Optimus’s grip there, using the momentum it had granted him to speak. He refused to falter from the optics that stared right back at him, reflecting his soul in a way that he found he lacked the words to describe. Another feeling joined him then, one just as familiar as some of the others he’d felt up until now. He hadn’t felt it in such a long time, so much so that it almost felt alien, yet the stirring within his spark reminded him that it was anything but. He felt exposed, his spark chamber being left feeling as if it was hollowed out & his soul flayed before the only mech he would have ever found the intimacy with to do so. Flashes of past experiences came flooding into his processor, leaving Megatron’s body to move forward before he even had time to process what he himself was doing.

He’d closed his optics at some point, he realized, as the darkness around him took form in his frontal processor. He could feel his denta parting as he formed his words, his hot breath ghosting the cool metal of the Prime’s faceplate, causing a layer of moisture to form on the space there.

“Before what, ” Megatron paused, his tone dripping with the hint of a tease. “It goes too far?”

Crimson optics opened slowly then, trailing up to drift into azure ones that blazed with varying layers of emotions that Megatron still couldn’t find the footing to dissect. There was something about the Prime’s demeanor that made him appear as if he was completely in control, yet somehow on the verge of breaking all the same at any given moment. It was as if the Matrix itself was not the only burden the mech carried, Megatron realized, yet he pushed the thought aside for something far more favorable. Before he could fully form his next thought however, the Prime spoke, the majority of his face still being hidden behind his battle mask as he did so.

“Yes,” Optimus whispered, his tone delicate & laced with a familiar sense of intimacy, a rebuttal lingering there on the Prime’s denta, yet it never left them all the same. It was almost as if he was afraid to speak more, lest he unfold even further to the mech before him.

It was frustrating how gently the Prime treated him, Megatron realized as the thought took hold in his processor & lingered there, & with another wave of frustration he could still detect the other was holding himself back. Crimson optics risked a glance below to watch as the Prime’s digits fidgeted seemingly without pause, the appendages shuffling as if they sought the feeling of a familiar frame in their touch (or perhaps simply running along with the Prime’s thoughts, he couldn’t tell either way). A deep chuckle resonated within the silver mech’s intake as he took in the sight of the Prime’s nerves on clear display, & he sought the opportunity to further the Prime’s frustrations by pressing their frames together in an intimate display of past affections. Finally, he began to watch his plan bore fruit as a frustrated grunt left the Prime, leaving the other mech’s optics to furrow as he attempted to smother the noise & return it to its origin deep within his frame. Being this close meant Megatron could finally not just see Optimus’s reactions, but feel them, & he was now able to watch with fervent interest as the mech began to shuffle uncomfortably within the space that the two bots occupied.

Yet it wasn’t all entirely undesired, Megatron realized as that familiar ember within his spark began to stir once more as he reveled in the rising build of other’s rhythm. Megatron dared not move, yet he found himself having not even needing to as Optimus & his chest plates bumped & rubbed together with a slowly building charge of friction that only served to further the building desire between the two bots. The deep rumble of the Prime’s engine began to growl in tandem with Megatron’s own as he pressed their chest plates further until the rest of their frames were touching in a series of ghosting touches, an intricate pattern of limbs beginning to form between the two’s shared bodies as Optimus’s servo slipped from Megatron’s forearm & settled on the upper part of the silver mech’s tibulen. They slowly began to shuffle closer like this more & more, soft whispers slipping from the Prime’s dermas as they continued in their dance of lingering desire. Each touch was leaving both bots in a state of building desire that neither of them could find the willpower within them to ignore, & that was definitely the least of it as unintentional touches lingering on either one’s forms quickly became intentional shows of affection & desires...

Eventually, a hard hitch in the Prime’s breath reached Megatron’s audials after he’d traveled from the Prime’s battle mask to the other’s neck plating where he made certain his glossa was slick with fluid before licking at the rigid metal there, coating it in a thick layer as he did so ever so slowly, relishing in the familiar rich layers of dust & metal it gave him access to before adjusting his denta & teasing at the space with his upper canine. It earned him another elicit sound from the mech above him, & Megatron used this opportunity to leave a trail with that very canine, dragging the tooth along the ridges & notches in the space there, taking his sweet time as he did so & gradually increasing the pressure before he reached the end of his path. The silver mech paused, albeit for a moment in order to drink in the rapid unraveling of the last Prime of Iacon here before him. If the mech before him was to be his downfall, then Megatron was determined to make the destruction mutual at the very least.

With the resignation settling deep within him adjacent the ember nestled deep within his spark did Megatron opted not to waste another moment, instead appointing in favor of adjusting himself slightly before digging both of his canines into the Prime’s neck plating in a dominant display of proclamation, that he would be his & no one else’s. If Optimus was his past, then he would surely be his future. Megatron’s chassis shook as the thought traveled down his backstrut & down to his pedes, leaving an electric trail that mimicked the others that had traveled through him previously as it did so. For once this entire evening he found himself not so reluctant to admit that this was their nature just as it was in their youth to have their fates intertwined, that he would always be tied to his fellow mech, regardless of their circumstances. And if this was the way he needed to remind his fellow mech of such a bond, then so be it.

If Optimus was to be his black hole, then he would serve to feed into the mech’s hidden desire for more until it overflowed if it was the last thing he did. He would be his quasar, that much he knew.

As sharp denta dug their way into the now heated neck plating did Megatron allow his pelvis to buck forwards in a fervent collision course for the other mech’s own pelvis, leaving the Prime to choke on whatever words were coming out of his intake & opting to moan instead, his body clearly feeling the effects of the cocktail of pleasure Megatron was beginning to brew. Another sickening wave of satisfaction washed over the warlord’s form then as Optimus’s hips bucked into his own the following moment, the other’s movements slowly becoming more & more eager as time went on. More soft whispers of incoherent mumbling left the Prime’s dermas as he began to fight for some semblance of control, his left servo reaching around Megatron’s rigid form & placing a hold on the other mech’s shoulder pad with a desperate grip. Such a hold forced Megatron’s form to remain as close as possible to Optimus’s, leaving little room for much else than for their pelvises to rock together in chasing waves of building pleasure as metal scraped upon metal.

Megatron was determined to continue such a sequence for as long as he could, gradually leaving trails of puncture wounds deep within the Prime’s neck plating & drawing out trails of Energon as he did so, only stopping to lap to drink in the now free fluid as it trickled down in stray trails down the Prime’s neck. He was determined to push the other mech further until he could locate his breaking point, the other bot now pliable in his servos as he maneuvered Optimus onto the cave wall behind them, using his momentum to slot one of his legs in between the large mech’s own, scandalously spreading the other’s tibulens apart as he did so in one smooth motion. It earned him the motion of Optimus tilting his helm further to the side to give Megatron better access, & that’s when he heard it.

At first it only sounded like more incoherent mumbling & soft moans that had left the Prime’s dermas up until now, but as he paused to let his processors adjust to what he had heard, that’s when the sounds became clear. Crimson optics snapped open to glare at the Prime above, leaving a pause in Megatron’s assault on Optimus’s neck plating as he did so.

It came in waves at first, just the first letter. Then it came, again & again, until it became clear, making the silence between the two mechs even louder in between each spoken whisper of the name. It caused the building lust within Megatron to come to a grinding halt & be replaced with boiling Energon within his fuel lines without warning.

“D… D-16, Please, ” Optimus whimpered, azure optics closed & trapped in the throes of the mech’s own self-serving fantasies.

Something snapped within him then as the feeling of his form heating from the anger alone in his fuel lines & his engine rumbled with newfound power. It left him feeling dazed as the next sensation that managed to squeeze its way into his processor was the sensation of his servo grasping around the rigid metal of Optimus’s neck, his digits squeezing down on the metal there with crushing force. Memories flashed into his processor of his fight with Starscream all those cycles ago, the memory serving to remind him of how the Seeker’s neck felt beneath his servo then, a rush of anger flowing through him not unlike he was feeling now along with the clear sound of crunching metal below his digits as he began to crush the other mech’s vocalizer. For a moment Megatron found himself swept up into the vivid memory, the details feeling more & more like reality as the moment went on before he heard the distinct clunk of a battle mask receding, leaving Optimus’s faceplate now exposed for him to see. It was just how he’d seen it last on the fateful day the Prime had banished him from Iacon, from his home, the day he’d lost everything. The other mech’s face still displayed the same mangled faceplate where the damage from Megatron’s blaster had scorched his left cheek. Various layers of scorched metal remained exposed & mangled, the warped metal there leaving a distinct map of damage his blaster had left that fateful day. Primus had healed many things that day from Orion Pax’s mangled form, yet Optimus still managed to sport that same scar all the same.

Crimson optics remained fixated on the Prime’s faceplate now, eager to avoid the warped side of his faceplate, tracking each desperate breath that left the Prime’s dermas as he kept his grip on the other’s throat. A twisted, crooked smile flashed over Megatron’s dermas then as his spark twinged from the familiar sight before him.

“Begging, are we Prime? Oh, how you’ve fallen. If only your precious Primus could see you now. If you want something, you’re going to have to tell me.”

As if to taunt the Prime further, Megatron tightened his grip on the other bot’s throat, earning him a mess of tangled words as the other attempted to speak through tangled weaves of glitched words & garbled syllables. Down below, he felt as firm tibulens seized hold of his own, locking him in place. The distraction worked well & long enough for Optimus to gather himself, if only for a moment to speak a few tangible words through his stuttering vocalizer.

“N…No… I, nghh—!”

Locked between the Prime’s tibulens, Megatron felt as the other’s form shifted in a conflicted struggle for more, powerful tibulens beginning to shake as the mech struggled to take in air & focus on the grip on their shared owner’s throat. Though Cybertronians didn’t need to breathe per se, the extra intake helped their processors operate with more clarity, & with Optimus’s optics beginning to glaze over from the lack of such operational viability, his shuttered words began to descend into crackles parting from his vocalizer that no longer resembled much more than the other’s desire for more. The other’s shoulder pads began to slump & Megatron felt Optimus’s knees buckle, the extra weight bearing down on his own knee joints as a result. With a small sigh of reluctance, Megatron relaxed his grip on the other’s throat, if only to keep him from passing out & allow the mech a moment to recollect himself. Such a pause allowed for Optimus to take in a sharp inhale of air, his glazed over optics beginning to clear ever so slightly as crimson optics tracked him like he was simply prey caught in the Decepticon’s gaze.

Though the sentiment of allowing Optimus a moment of reprieve wouldn’t account for much as the servo that belonged to the silver mech’s injured arm slinked down to Primus’s chosen’s heated tibulen silently, & Megatron risked a glance from the tantalizing sight that was Optimus Prime struggling to catch his breath down to their conjoined tibulens below when his digits picked up the sensation of a sticky layer of transfluid now coating them. A ravenous heat shot through the large mech’s frame, stopping on its journey to his stomach tanks to feed that all too familiar ember in his spark, the feeling ebbing within his spark chamber before completing its journey. A hard shiver racked the silver mech’s frame along with a clear smirk spreading across his faceplate that he didn’t even dare try to hide. When azure optics finally reopened above him his gaze was there to meet them, watching as the Prime’s optics danced across his features, taking in the face of a mech that knew he had the hero of Iacon like putty in his servos.

Without a word as Megatron continued to lock optics with the mech above him did his free servo slot its way between powerful tibulens, the motion earning him a stifled shiver & moan from the mech above him. Megatron’s engine rumbled & roared louder deep within his chassis, the sound being matched by the eager reply of Optimus’s own engine. Their frames remained as close as can be with the sound of each mech’s respective forges causing them to rattle & bump into each other slightly from the sheer force of the vibrations above, & with each creeping inch that thick servos managed to slip between the Prime’s tibulens did the warlord manage to slink his way next to the seams in Optimus’s armor, his digits deftly sliding into the space between the mech’s armor plating & protoform respectively. He danced one of his digits at the edge of the seam, a small electric current shooting up & through said digit, journeying all the way up to his spark.

Relishing in the feeling it gave him & the sweet sounds it was drawing out from the mech above him, the silver mech’s digit began deftly circling the space there, dancing between the feeling touching raw metal & the armor that protected it. Yet here he was, slipping past all of the Prime’s defenses. And he reveled in it.

The satisfaction from such an activity finally began to reach the Decepticon’s own groin then, his spike slowly beginning to pressurize in the confined space. Though Megatron’s processor opted to instead focus on the sight before them, watching as the Prime’s form quickly became racked with waves of building charge, a series of shivers cascading through his form along with the consistent rhythm of his engine idling within his chassis. The servo that had previously retained a powerful hold over the other’s neck plating now began circling the sites where Megatron’s canines had created their puncture holes there, his thumb digit in particular caressing one of the deeper holes he’d created not too long ago, the digit dipping into the space there & coming back out with a sliver of Energon as a reward. Down below, Megatron still remained trapped by the other’s own tibulens keeping their hold on there, though he was reluctant to call it a forced occupation as he drank in his fellow mech’s crumbling resolve. To see Primus’s beloved warrior falling prey to old emotions & the lust that followed was enough to bring the warlord to the realization that their dynamic had truly shifted since that fateful day, & he intended to take full advantage of such a change.

Flicking his frontal processor back to the matter at hand, the digit that had found its way into the ruby & azure mech’s plating receded to reach between said mech’s tiibulens to smear the now thick layer of transfluid that had formed there as a result of his teasing. The smirk that had found its way plastered all over his faceplate shifted in something more dark, a sinister lust working its way into crimson optics as deft digits swirled in the fluid there & eventually reaching to try to pry their way past the Prime’s defenses that prevented him from accessing his valve. Though this was something he’d have to earn, Megatron surmised with a reluctant resignation, shifting his movements down below at the other’s valve into a steady rhythm of smooth circling motions, as if he was already stimulating the other’s primary node.

“Already had enough, Prime? Look at you, leaking like a needy whore . Primus would be ashamed to see you like this.”

A strong digit was used then to dig into one of the openings he’d created on Optimus’s neckplating then & the paneling above the other mech’s valve in one synchronized motion, earning him a strained moan that Optimus couldn’t find the will within himself to restrain fully, the sound falling gracefully from the mech’s dermas as a result. It earned Megatron another flushed wave of heat making its way to his spike as it now began to throb further, almost fully pressurizing within his own paneling. He could feel the feeling of his prefluid pooling within the space there in the back of his processor & he opted to satiate the hunger by pressing his & the Prime’s shared chassises together then, the sound of their combined engines continuing to harmonize in a symphony of building fervor as their bodies shifted & their sparks hummed in tandem. He watched with tangible fervor as azure optics strained to remain focused on the separate simulations racking their owner’s frame, watching as they feverishly flickered between the predatory gaze anchored to them & the sensations below. Each sensation left the Prime more needy than the moment before, leading to a steady charge that was soon to break under the strain of the two bot’s shared lust.

In the midst of the sea of dirty thoughts within his processor did such a piece of him register a firm servo on the back of his pelvis, urging Megatron forward impossibly closer as a heated breath escaped the Prime’s dermas & onto his own heated cheeks, serving to increase the temperature there tenfold as a result. Megatron decided to allow the realization that the Prime had snuck past his defenses in the midst of everything in favor of what was to come next, the words coming from the Prime in the next moment only serving to further his own sense of surprise.

“I could say the same about you,” Optimus whispered, a sliver of his former resolve returning to him as he spoke, albeit slightly. His form still continued to tremble from the stimulations he was being provided, leaving the azure & ruby mech in an attempt to steady himself further as Megatron replied.

“Hmph. Whatever you say,” Megatron shifted his form slightly, slotting their forms together like two pieces of a long lost puzzle. Another realization flickered to the front of his processor then as he took a beat to absorb the moment between himself & his former lover, taking in the Prime’s aura as he did so. Despite their current predicament & the Prime’s clear unraveling before him, the mech appeared more confident, that much even Megatron couldn’t deny. He kept such a thought to himself however as he sought to further his control over the situation then, opting then to surprise Optimus with something he would definitely not see coming.

“Though, with the state you’re in, I think we’re well past the need for words, don’t you think?”

Trailing the end of his query, that sinister smirk flashed across Megatron’s faceplate, the deviousness & lust on full display once more as it appeared. Though there was a primal hunger there along with the layered resentment he still harbored for the mech before him, serving to further the urge to provoke his fellow mech with whatever would elicit the reaction he sought to draw out.

With one smooth motion & a gentle click from the space below did Megatron’s spike sprung free from its previous restraints with his paneling retreating in one smooth motion, allowing the member to spring free & to arrive dripping with a generous amount of pre-transfluid as it did so. It remained nearly the same from the time before he’d obtained his first sacrificial cog, though with the attainment of the deceased Megatronus’s cog did he inherit the Prime’s size in addition to his already generous own, as well as a newfound girth & prominent nodes that pulsed long the sides of the member with a passionate shade of red that accompanied the rings of light that he still managed to retain from his original design. The sight clearly caught the Prime’s attention, a clear hitch in his breath that the mech still struggled to hide. A satisfying wave of confidence washed over the silver mech then, his spike gently tapping against the Prime’s inner tibulen as he remained locked between the other’s firm limbs.

Using the momentum to his advantage, Megatron closed the gap between them both in one swift motion, their dermas finally connecting in a rough kiss that succeeded in drowning out any protests the Prime had been beginning to form. Both mechs quickly melted into the kiss, though Megatron began his conquest for control by forcefully pushing his glossa past the other’s defenses, taking his time to lick around the space there & further his own intoxication by drowning in Optimus’s taste. A heavy weight began to descend on the silver mech’s form then as he felt the Prime’s knee plates buckle, followed by a heavy shiver that managed to reverberate through mechs as both bots attempted to steady themselves. Megatron refused to relent however, using as much force as he could muster to keep the Prime upright & against the wall, the other’s stifled moans somehow managing to escape the kiss & echo off the cave walls.

They became trapped like this with both mechs refusing to relent & it wasn’t until Megatron felt a firm servo against the back of his helm with Optimus’s other servo gripping one of his shoulder pads did he take in the additional sensation that had joined the others he was experiencing below. A wave of lust ran through him & the ember within his spark burned ever so brighter once he felt the sensation of his fully pressurized spike flush against Optimus’s dripping valve. At some point the mech must’ve opened his paneling, though the timing didn’t matter. Still locked between the Prime’s tibulens, Megatron began to slowly thrust his pelvis, effectively sliding his now throbbing spike through the outer folds of the ruby & azure mech’s folds. One such thrust brushed oh so perfectly against the other’s exterior node, leaving both mechs to release a harmonious moan together as a result.

Finally after what felt like an eternity did Megatron break the kiss between himself & Optimus, their optics locking together as heavy breaths escaped both their forms once they had gained enough distance between themselves & a scandalous trail of fluid connected their dermas together. With a small stretch of silence did both bots form their respective conclusions for what was about to happen next, though Megatron wasted no time in this regard, continuing his thrusts between Optimus’s tibulens in a pace that gradually began to build into a much faster tempo, the Prime’s mesh coating his spike with thick transfluid with each successive thrust. One of the warlord’s servos managed to slip between their conjoined forms amidst the fervor, finding a path to Optimus’s valve as he did so & using his thumb digit to coax small, steady circles on the mech’s exterior node. Azure optics whirred & clicked in the wake of Megatron’s gaze as he watched as Optimus revelled in the sensation, the other mech’s servo still retaining their grip on the back of his helm as the silver mech continued his assault on the other’s valve & node. The sensation of Optimus’s slick valve coating his spike with transfluid combined with the vibrations of their shared forms nearly sent Megatron over the edge then & there from the combined feeds of pleasure, though he opted to retain control as best he could in favor in increasing his tempo in order to elicit further stimulation from the mech before him, the clear sounds of wet mesh mixing with the collision of both mech’s forms colliding as his desperation for a climax came rising to the surface.

Eventually the sound of heavy breaths & cooling fans clicking on reached Megatron’s audials, the realization dawning on him that they were not only Optimus’s, but his own as well. Whilst his right servo continued to stimulate the ruby & azure mech’s node did his other obtain its own vice grip on the mech’s pelvis, using its hold there to force Optimus’s hips into the rhythm of his increasingly erratic thrusts in his quest for reaching his climax. He became lost in his quest for pleasure then as Megatron broke his gaze from pools of azure optics nestling his faceplate deep within the crook of Optimus’s neck. With his helm there, the only sounds reaching his audials were the chorus of heavy breaths & moans along with the clanging of metal on metal as the silver mech’s movements continued, though one line of speech rumbling from the Prime’s form managed to slip its way into the stream of incoming audial feeds that were entering his processor.

“M– Megs, hahh… D,” Optimus whined, his vocalizer coming out in a strained & desperate attempt to speak above the cacophony of sounds around him. “In– Inside, please… I need you… inside… ”

As if you have to ask.

With the Prime’s desperate plea for more only serving to anchor itself at the frontal unit  with increasing urgency, & it was a plea Megatron could no longer afford to ignore. With a heavy & reluctant breath he removed himself from his place at Optimus’s neck, separating their forms to grab ahold of the Prime’s shoulder pads & turn him around so he was now facing the wall in one swift movement. A soft cry of surprise came from the other mech then as Megatron’s towering form pressed itself onto his backside, the bot’s faceplate turned sideways so he could maintain his gaze on Megatron unbroken. Luckily the side Optimus decided to turn towards Megatron was the one without scarring, leaving Megatron with no distractions as he used one servo to keep Optimus pinned to the wall with a servo on the side of the mech’s helm & the other holding his spike so the tip was aligned with the former’s valve, teasing the slick entrance there as he did so. Though the Prime remained like putty in his servos he began to be met with a small amount of resistance, though Megatron barely felt justified in calling it so as it was more of a tease as the Prime’s backstrut arched scandalously towards his own form, the other’s valve puffy & dripping, ready for whatever was to come next.

Wordlessly, Megatron lined himself up with the other’s valve once more until he found the perfect angle & began slowly teasing the tip at the other’s entrance, the very heat of the space singing to him like sirens, begging him to inch himself further into the tantalizing warmth there. The warlord stifled a greedy moan that began to rise from his intake as he felt the Prime’s form shake at the tease, the other’s hips subconsciously back towards the tip of his spike & urging the member in further as he did so. Eventually, he began to thrust his hips, slowly, drawing out every quivering moan & needy vibration of Optimus’s form that he could, using only the very tip of his spike as he did so. He began to take in the feeling of the tip barely making its way past the outer folds of the other mech’s valve, slick sounds of transfluid coating his spike impossibly wetter as he continued his motions. From ahead of him Megatron could pick up the Prime’s own stifled moans rising from his intake & escaping the flimsy guard of his dermas & into the cave air, the sounds reverberating in the natural silence of the space & into his audials. He teased him like this until he could feel the azure & ruby mech’s form shift & crimson optics traveled upwards, meeting azure optics that swirled with a concoction of lust & thrumming desire.

There, hidden within such a heavy gaze, Megatron could detect the slightest hint of something without a true name beneath all the lust & fervor of the other’s gaze. The look was too complex, too unnerving to fully dissect. He felt like if he stared at it for too long it would break him, & all his resolve would crumble then & there with no path to recovery left for him to follow. Cycles upon cycles of emotions laid buried in that look, & an aching feeling threatened to careen the silver mech off course when he felt his body take hold, his optics snapping closed as he pushed the Prime’s helm back against the wall in an effort to divert his gaze & thrusted. He felt multiple waves of emotions wash over him then, senses he hadn’t felt in dozens of cycles that left him feeling raw & exposed. With his spike thrumming with charge & being slotted deep within the other’s walls, Megatron managed to pick up the sound of the other’s fans stepping up a gear, the mechanisms whirring & clicking with an elevated sense of distress as Megatron slowly began to shift his hips into a slow & steady rhythm of thrusts. A satisfied moan came from the mech before him then, leaving for a moment crimson optics to flutter closed as he took in the feelings & sensations swarming him, old memories serving to flood into his processor as the near pitch black darkness enveloped his senses.

There, in the darkness did his thoughts begin to wander, picking up every thrum of pleasure & old memory that threatened to sway him off course. They began to trace back to what he was feeling in the present, the feelings & emotions coming in lapping waves that were slowly building into a typhoon of nostalgia. He felt himself shift as strong servos gripped the helm & hip of the mech he once knew in a vice grip, the heated touch of such metal feeling familiar in his grasp & serving to ground him ever so slightly back to reality, yet alien all the same. He felt as the other’s movements shifted & moved in tandem with his own building pleasure nipping at the back of his pedes in the subconscious part of his processor. His thoughts shifted to the sounds around him then, the creaking of new joins under strain from both their shared forms aching from the strenuous movements they were engaging in to the sound of moistened mesh grinding with the measured & precise movements of Megatron’s hips. In the ocean of such sensations did Megatron fool himself into believing that the form below him was the same one as before, & when he opened his optics he’d be met with reality, the all-too-familiar sight of a mech he had onced loved shivering below him.

But it wasn’t the same. Not anymore.

And it never would be.

Crimson optics snapped open then, reality slapping Megatron in the face like a freezing spray of frigid ocean water running through his cables, the sensation washing away any sense of peace & tranquility he’d obtained in the darkness of his mind. Instead he was met with reality, the tinge of sorrow that had snuck its way into his spark turning acidic as his engine rumbled almost violently as he attempted to regain himself, feeling as the familiar sting of anger attempted to wash away the sorrow as strong servos doubled the strength of hold on the Prime’s helm & pelvis respectively. A small noise came from the Prime then, the other’s eyebrow ridges placed in a look of confusion & curiosity as Megatron’s demeanor shifted so abruptly, though the former had little time to form any words as the warlord began thrusting into the mech before him with a new & relentless pace, the length of his spike reaching the depths of the other’s valve & threatening to breach the threshold of Optimus’s forge as he did so.

Stuttered gasps & moans escaped Optimus then as Megatron continued, crimson optics now locked on to anything but the azure gaze that begged to be answered in a silent cry of want as the ordeal continued. Slick sounds of transfluid leaking from the Prime’s valve continued to be abused, the wet walls of the space sucking in Megatron’s throbbing spike with each successive thrust. Such a sensation caused the silver mech to double over, retaining his grips on the Prime’s form as he forced his hips into a rhythm as fast as they could go, rapid sounds of clanging metal filling the air as he did so. Crimson optics slitted open ever so slightly to catch the sight of Optimus’s nape exposed & waiting, & for a moment Megatron felt generous, opting to lean down & place a rough bite on the heated metal there & stay . Now attached to the Prime’s form in more ways than one, he could feel the other’s Energon humming in the mech’s fuel lines as the bite earned him a needy cry from the mech below, the noise leading into the motion of the Prime arching his back impossibly further into his own form, forcing Megatron’s spike to the very depths of the other’s valve as a result.

The motion caused a moan to slip from Megatron’s dermas, causing his grip on the nape of Optimus’s neck to loosen in the process. Crimson optics slipped back closed then as the sound of more pleading gasps & whispers reached his audials once more. The servo that gripped the Prime’s helm slid around to place a few digits into the other mech’s intake, thick transfluid covering said digits & causing the other’s words to become stifled as his intake was effectively stuffed. Taking in the sensations then did the feeling of his approaching overload creep back into the front of his processor, his spike continuing to thrum with charge as his form shifted into auto-pilot & his thrusts reached a relentless pace, his own vision becoming blurred as the desire began to overtake him & his overload finally reached him in an almost overwhelmingly successive waves of pleasure.

Cycles upon cycles of pent up overloads finally released into Optimus’s valve then, pouring into the space there by filling each & every crevice of the space as Megatron’s own form began to shake from the overwhelming sensations of it all, his engine joining in in harmony as his own fans blasted on at full capacity from reaching his overload. Heated puffs of air left his dermas in thick clouds of moisture as he exhaled heavy breaths as his overload continued to overtake him, his own pelvis flush with Optimus’s own as it went on. From perhaps the sheer force alone from his hips continuing to stutter from the lingering waves of pleasure, the sound of servos scraping & slipping further down from the cave wall ahead of him caused crimson optics to catch the sight of Optimus slipping from his place on the wall. The Prime’s own form was releasing waves of steam out of his smokestacks as his pedes shuffled in staggered movements until he eventually lost his grip on the cave wall & landed on his knee pads & servos on the cave floor below.

Megatron watched through heated optics as his form went numb for a moment, a wave of nausea & disappointment washing over him as he watched Optimus collapse onto the cave floor below. His spike had slid out of the other’s valve of course, leaving a trail from said spike to the other’s puffy valve that began to slowly relax & release his gift to the ungrateful mech before him. The transfluid he’d worked so hard to pump into the depths of the Prime’s valve was leaking out now, wasted as it pooled onto the floor & trickled down Optimus’s inner tibulens. He watched as Optimus risked a glance to face him, azure optics still ablaze with a lust that was yet to be satiated. As he analyzed his gaze more, a hidden challenge was detected beneath such a gaze, & the ember within Megatron’s spark chamber blazed so hot he could swear it was going to burn a hole straight through his protoform & out his chassis. A confident & familiar smirk flashed across Megatron’s dermas then as he accepted the challenge without hesitation, his form moving without him thinking as he bent down to the Prime’s level, joining him on the floor & pulled the ruby & azure mech’s upper body back upright so his backside was flush with Megatron’s chassis. Their shared forms reconnected then, sharing their energy fields as Megatron’s throbbing spike continued to twitch alongside the Prime’s heated armor, eager for more stimulation as it sat flush against the Prime’s backside, so close to his aching valve that begged for further attention.

So close to the other’s field, the other’s gravity took full effect, old habits taking over whilst mixing with newfound desires as large servos ghosted over a form they’d felt countless times, yet different all the same. Thick digits managed to slip past the Prime’s defenses once more, returning to familiar easy-to-access crevices in the Prime’s armor, easily reaching the other’s sensitive protoform through such cracks in his defenses as he continued to explore the other mech’s vulnerable form. Darkness now enveloped Megatron’s vision once again as his optics slipped closed, his other senses taking command of his processor. Deep, hitched breaths & light gasps slowly but surely reached his audials in smooth & gradually rising whispers, the form below him shifting & shuffling slightly as subconscious servos moved from invading the other’s armor plating to the front of the mech’s pelvis, one servo taking hold of the other’s spike at the base while the other pulled the Prime flush to his own form by the other’s scandalously thin waist. A heated wave of lust rolled over Megatron then as he relished in the sensation, a light growl leaving his intake that was barely loud enough to be heard as he felt Optimus’s form freeze up momentarily below him once he’d taken hold of the other’s spike within his servo before the other mech slowly began to relax, though his energy field remained abuzz with an intense charge that was yet to dissipate.

With his optics still closed, the servo that had taken hold of the Prime’s waist moved instead to one of Optimus’s servos on the cave floor below, sliding over the other’s servo before intermingling their digits with careful placements & insertions across & between the other’s digits. A staggered breath left Optimus then & his armor plating shivered against his protoform as Megatron noticed the other take in what he’d begun doing, both mechs falling into a familiar song & dance of chirolinguistics that they engaged with so often in their youth. Returning to the practice left such a sensation feeling almost alien as he traced familiar paths & connected with the sensitive sensory receptors across the other’s servo, attempting to follow what he thought were familiar paths of travel as he continued. After not using such a form of communication for so long he almost began to doubt if he was performing it correctly, though the twitches & waves of emotions transferring from Optimus’s energy field & into his own was more than enough confirmation that what he was doing was working without a single drop of doubt left in his processor. Without a doubt Optimus was now feeling every ounce of his desire & frustration towards the other mech, & with a silent confirmation of Megatron’s servo beginning to glide across Optimus’s azure spike did he communicate to his former lover that this whole evening was far from over.

He started slow for a few moments at first, dragging his digits along each engaged node he could find along the other mech’s spike, drawing each slide over node out as long as he could before reaching the flared tip of said spike, briefly pressing his thumb digit down on the center before dragging his servo down to the base & repeating the process. Each successive completion of the loop slowly but surely began to render the Prime a whining mess with each passing moment, leaving the bot unable to hold back the sounds of pleasure that rose from his intake as small shoots of pre-transfluid began to leak onto Megatron’s digits. Joining in the sensations, crimson optics opened just enough to catch the sight of Optimus trembling below, azure optics sensing the gaze on them & flicking back to meet Megatron’s own. Refusing to back down, the silver mech continued to tease the other’s spike with slow thrusts at first as his helm traveled down to capture the other in a smothering kiss that was anything but gentle as he plunged himself deep into the wetness of the other’s mouth. Optimus’s taste immediately filled his senses as his field expanded, leaving Megatron further enveloped in the other’s throes as he attempted to regain some sense of control, deepening the kiss & slipping his glossa past the Prime’s denta.

He explored the other’s mouth then, licking around the space there & dancing with the other’s own glossa as he refused to relent. Megatron waited until he felt the other’s form weakening after a few moments, granting his old lover a small boon of mercy as he disconnected the kiss, a deep groan rumbling from the Prime’s chassis as the kiss was broken. Both mechs gasped for air then once they disconnected as a scandalous trail of fluid connected their dermas as their helms parted, the familiar sight sending yet another agonizing wave through the Decepticon warlord as his optics widened slightly further in order to take in such a sight, his pace picking up on the other’s spike abruptly, forcing the other mech to the edge of a quickly approaching overload. The ruby & azure mech no longer seemed to be holding back much of anything as azure optics whirred & clicked from the countless thoughts & sensations flooding his processor from every sensation beginning to crash into him & overwhelm him all at once. Eventually, the pitch in Optimus’s voice began to rise from the depths of his vocalizer, his fans clicking on into overdrive as his form began to quake from his inevitably approaching overload. He almost wanted to give it to him, Megatron thought for a moment, contemplating the thought in his processor if only to watch the Prime finally & truly unravel beneath him until the thought was replaced by a more favorable line of action, beating its predecessor by the slimmest passible margin.

Following his new line of thought, Megatron slowed his relentless pumping of the other mech’s spike, earning him a small growl from the other mech as Optimus realized what he was doing after a beat. Seeing the hero of Iacon so disheveled & practically begging sent a surging heat down to his spike, the member quickly re-pressurizing from the senses flooding Megatron’s form & processor that seemed almost endless. Though he’d ceased his motions on the other’s spike, a carefully placed digit continued to tease the other mech’s tip as he gently placed pressure down on the site, Megatron’s other servo that previously communicated wordlessly to the Prime through chirolinguistics traveled upwards to the other mech’s helm, tilting the azure helm up so crimson optics pierced azure ones below in a direct gaze that Optimus had no chance of avoiding.

“Tell me, Prime,” Megatron purred, his tone rumbling with the hint of a tease as he motioned small circles on the tip of the other mech’s throbbing spike. “Do you want to overload? Right here, in your enemy’s arms, practically begging to be sparked?” Wordlessly, Megatron’s servo slid down from the tip of Optimus’s spike down to the base, a flash of surprise echoing across the mech’s optics as he took hold of the girth & squeezed.

Then, as if attempting to retreat back into old habits, Optimus struggled to hold back a wavering whine as the true intentions of the warlord’s words finally set in, a sliver of resolve returning to the Prime as he exerted the effort needed in order to reply.

“You… You wouldn’t,” Optimus emphasized his point by narrowing his optics at the mech above him, though every wave of energy emanating from his form & every flicker of his optics betrayed him as he writhed & grinded against Megatron’s towering form. Together, like this, they would consume each other until there was nothing left. Until the both of them were left in ruins with no way to return, just like that fateful day in Iacon. A day neither one of them would be able to forget…

Until all are One, Megatron scoffed internally as the thought entered his processor.

The smirk on Megatron’s dermas widened then, a wicked look flashing across his optics as a familiar darkness settled there as the idea fully formed in his processor as a direct result of Optimus’s words. What better way to ruin Iacon’s hero than have him returning to the capital a carrier of his worst enemy’s spawn, charged with his seed & burdened by an offspring that should have been created out of love than the ruins of two bots that once called themselves lovers.

Such a dream was lost long ago, buried under the rubble of Sentinel’s statue.

Megatron tilted his helm then, shifting his form until his spike was aligned with Optimus’s valve, shoving himself back into the slick space there effortlessly. The action earned another stifled moan from the Prime then, & it only further served to fuel the ember within his spark as he began to thrust ever so deeper into the other’s valve with the sole intention of leaving his mark within the Prime forever.

“Oh, but I would,” Megatron purred, his thrusts falling into a rough rhythm as Optimus gritted his denta in response to his words, his form collapsing further onto the cave floor below from the sheer force of the warlord’s thrusts. His rear rested elevated in the air then, leaving Megatron free to press his weight down onto the Prime’s shrinking form.

They fell into a steady rhythm like this, a push & pull of pleasure as the warlord continued his efforts to breach the Prime’s gestation chamber, though Megatron barely had to force Optimus to submit. Any resistance was simply a continued version of their foreplay as he angled his & Optimus’s hips in order to deepen his thrusts so the tip of his spike began testing the fortitude of the mech’s inner paneling. Pulses from the internal mesh of Optimus’s valve continued to almost suck Megatron in as he kept his former lover’s pelvis flush with his own, struggling to stifle rising grunts & moans from the depths of his intake that threatened to slip past his dermas as the feeling almost sent him reeling with each successive thrust. One servo remained attached to Optimus’s own that rested on the cave floor, continuing to convey the silver mech’s deepest desires to the other as he continued his assault.

Crimson optics slid down to the sight below, watching as Optimus’s swollen dermas struggled to suck in air as his form was rocked back & forth from the motion from each successive thrust from the mech above him, his faceplate currently pressed snugly onto the rough & rocky cave floor below, no doubt leaving new scratches to decorate the mech’s already scarred form.

Eventually, something stirred within the depths of Megatron’s stomach, & he knew then with a familiar train of thought that his next overload was nipping at his heelstruts. The combined sensations of the slick valve sucking him in along with the cries his thrusts earned him into the mech below him caused his overload to approach a bit too quickly, a thought he knew to be true but was still reluctant to admit. Somehow amidst the chaos, crimson optics locked with azure ones, & leaving Megatron with another idea that left no room for doubt as he forced his own thoughts to come to a staggering halt. The decision left an optical ridge to rise slightly on Optimus’s faceplate, the mech appearing puzzled at the sudden change of pace before Megatron began to speak.

“Flip over,” He demanded, his tone resonating in a monotonous pitch, leaving no room for negotiation as he delivered the command. Normally he’d force the Prime into whatever position he desired, but his current plan required the Prime’s cooperation (as much as he was reluctant to admit, much less wanting to admit such a thing outside of the confines of his processor).

After his words had left his dermas, something shifted in the Prime’s expression into that all-too-familiar expression he’d never been able to find the footing to dissect, even in their youth. The thought began to swirl around in his processor & irritate him when it was then quickly cleansed by the soothing rumble of Optimus’s voice rising from his voice box.

“Already demanding more,” Optimus sighed as he shifted away from Megatron’s form in order to comply with his demand. A shaky sigh left the mech as he shifted his hips, the movement forcing Megatron to shuffle along with the other’s movements, his spike struggling to remain in the other’s valve as he adjusted himself to their new position. Crimson optics fluttered closed as their owner’s pulsing spike struggled to remain within the confines of Optimus’s valve, such a struggle consuming the mech until Optimus settled into a position that had him on his back, aft placed on the ground with his backside placed snugly against the cave wall.

Azure optics locked yet again in that moment, & for once Megatron felt the aura of the other mech in full force. Yet another challenge flashed across Optimus’s optics then, but before silver dermas could part to comment on such a demeanor, the next thing the Prime did nearly sent the Decepticon into a crazed state then & there. Powerful tibulens spread apart slowly in one smooth motion until a clear view of Optimus’s valve was revealed to Megatron in a proud display of transfluid leaking out & onto the cave floor below. Optimus’s helm tilted slightly to the side then as crimson optics flickered feverishly over the Prime’s form, catching the sight of old bite marks & scratches from their glory days that the Prime had never bothered to buff out. Old markings from when Megatron’s spark was much lighter & their love meant something more tender & full of life & promise. Now the present left the two of them much more burdened, the thought weighing heavy in Megatron’s processor before he swapped it with another. Once again he would give into his spark, though he wouldn’t allow himself to do so without strings attached.

He shifted towards the Prime then, optics never breaking contact with the other mech as he all but crawled towards the other mech. Pulled in by the other’s unrelenting gravity, he craved to feel safe within the throes of Optimus’s pull. To be flayed & dissected underneath the other’s gaze & emotions whilst he attempted to silence the turmoil within. Though with a sense of resignation did Megatron release himself yet again. This pain would always be a part of him, yet, for just a moment, he could allow himself to forget. To numb himself as he laid claim to a mech that was already his, just as much as he belonged to him.

Eventually, Megatron found himself slotted between the Prime’s tibulens as he examined the flat line the other’s dermas sat in, yet his optics remained ablaze with the ringing challenge Megatron was all too happy to rise to. A fragile moment of peace lingered in the air as the fictitious & haunting feeling of the Prime’s battle axe lingered over the nape of his neck as he stood at the threshold of a hidden tripwire that sat between himself & the Prime. Slotting his lips to Optimus’s own, he watched as azure optics fluttered closed, another quirk the silver mech was all-too-familiar with, he remembered as the taste of Optimus danced over his glossa. However, as azure optics fluttered closed, crimson optics remained open, albeit barely; just enough to catch the sight of the Prime melting back into him yet again. Forcing his own optics closed, the warlord allowed a low growl to leave his intake as he used his upper canine to dig down onto the mech’s upper derma, dragging the tooth down until he caught the other’s lower derma in his pathing until he used the pressure there to draw out a sliver of Energon that leaked gracefully into his own intake. A wistful moan left the Prime then as he licked at the free fluid there to catch any stray droplets of Energon, doing so over several passes before doubling his efforts, plunging the mech into yet another suffocating kiss as he did so.

Using the momentum the kiss had earned him, Megatron used his weight to press the mech before him impossibly further into the cave wall, the natural flora & fauna around them reaction to the stimulation, illuminating the space around them in a gentle glow as they did so. He began to return to his previous pace of thrusting into Optimus then, leaving little room for much else than for his processor to track & log the sounds of the Prime’s rising vocals as both mechs began to approach their shared overloads. After the two had shifted, one of Megatron’s servos returned to Optimus’s spike while the other found its way back to the other’s throat, holding him there as he licked around the space of the other’s intake & kept him pinned to the wall.

Just as before, the rising cacophony of emotions & sensations left Megatron nearly overwhelmed as his spike slotted itself impossibly further into the valve it thrusted so relentlessly into, & eventually his efforts bore fruit as the sound of his fans whirring at full capacity reached his audials once again & the energy fields between himself & Optimus crackled with energy. With a shift of Optimus’s hips he found the perfect angle, the very reaches of his sensory nodes detecting the smallest amount of free room left to explore within the very depths of the former’s valve, & that’s when he did it. With one final series of successive thrusts, the flared tip of Megatron’s spike finally breached the innermost depths of Optimus’s valve in an overwhelming sense of satisfaction as he bred the last of the Primes like an animal in heat. Another distinct clink! reached his audials as the mech’s gestation chamber finally accepted the intrusion, & he began pumping his transfluid into the forge that accepted his seed ever so greedily.

The intrusion left Optimus to deal with the most violent shiver Megatron’s ever experienced, witnessing as the completion of his task left the Prime rendered utterly silent in a silent cry as he was pumped & filled to the brim with his worst enemy’s transfluid. Crimson optics watched as azure ones flickered on & off as the mech before them struggled to remain online, though eventually after a series of rapid flickers did Megatron watch as Optimus gradually began to power down, his systems no doubt making micro adjustments by the microsecond to his internal systems as they prepared their owner to become a carrier. Though before Optimus fully powered down, crimson optics widened as they caught the flash of a gentle smile gracing & flashing across the Prime’s dermas before he eventually shut down, watching as the smile disappeared from the mech’s dermas as quickly as it had appeared, azure optics finally powering down with a gentle whir & whine as they gave in to the demands of the internal systems that commanded them.

Eventually, once the waves of pleasure began to ebb from Megatron’s form did he take in the sight before him, the fruits of his labor finally sinking in as he took in one last look as his spark caved in from the sight of his unconscious nemesis. The ember within him flickered out once more, any heat dissipating from his chassis as he gathered himself, a pregnant pause passing as he lingered on the sight of the powered down mech before him, so vulnerable & easy to destroy.

But he’d already done enough. There was nothing more he could gain from this.

It was only a distraction, after all.

With a pang in his spark & his subsystems commanding his spike to return to its sheathe, Megatron rose silently, dusting off a few pieces of dirt from his frame as he rose from the cave floor before walking a few steps away from the unconscious form of his former lover, the other’s helm resting against the cold wall of the cave as he laid there. He managed to make it a good distance away before the ache in his spark churned & he stopped with an abrupt scrape of his pedes coming to a staggering halt on the rough cave floor below him. Strong servos twitched at his sides, the aching pain of his sparking & injured shoulder returning to him as his systems flushed away the sensations & chemicals of the lingering pleasure his overload had brought him, several banners of alarm flashing across his HUD as he was reminded of his injury. He could tell his processor was doing its best to distract him, but it was barely working as is.

With one final ache that threatened to split his soul in half, he dragged himself away from the sight before him, & began blasting at what appeared to be the weakest point in the cave wall with his fusion cannon as a steady stream of coolant began leaking out of the edges of his optics & onto the cold metal of his faceplate.

He tried to ignore the tears staining his faceplate then as he let the blasts from his cannon fill his audial receptors, his optics clicking & whirring to focus on the newly created hole in the wall that would serve as his escape route.

—

When Optimus finally awoke, the first thing he was met with was darkness.

Slowly but surely his optics flickered online, sparks of light filling his vision as he attempted to take in his surroundings. Visions of bioluminescent light filled his optics as he attempted to shuffle himself upwards on the cave wall that mirrored his backside, the sight at the far side of the cave finally coming into full view as his vision finally cleared. Looking ahead, the sight of a large hole came into view, & with it, a way out. With a heavy sigh leaving his frame, he attempted to shift his weight in order to put his pedes underfoot, & that’s when he felt it.

A heavy, solid weight sat within his chassis, anchoring itself just below the Matrix. Coming to his feet, he reached a servo to press down gently on the metal there atop his protoform & felt the distinct sensation of a strong hum joining alongside the power of the relic within him. Azure optics widened then as the realization dawned on him, optics flicking up to check his own subsystems, a sinking feeling entering his spark chamber & gutting him, leaving him hollowed out & scraped raw as the alerts came rushing onto his HUD.

There was no mistaking it as one alert popped up at first, then one after the other as Optimus attempted to accept the news as quickly as it had confounded him. A heavy feeling rested on the edges of his optics as his processor finally began to catch up with the commands of his subsystems, commands he’d been unable to attend to since he’d fallen into stasis. He risked a slow glance around the room, taking in & logging the absence of a particular silver mech that left him with this feeling & the new life within him. A new ache settled within his spark, but also new hope. A fragile smile graced his dermas, eager to falter as his servo remained atop the gentle hum of the new spark forming within him.

His voice carried the sorrow of what could likely never be, yet also the hope of what could be. Whatever might come, he’d be ready.

“Just us now… Now, what to name you, little one.”
