Work Text:
The heavy, rhythmic thud of metal on metal echoed through the silent, vaulted halls of the Iacon Archives, a percussive counterpoint to the gentle hum of data-streams and climate regulators. Each impact rattled the stillness, a punctuation mark of pure, concentrated force.
THUD-CLANG—SCRREEE—THUD-CLANG.
Optimus Prime's immense frame drove downward with a relentless, hydraulic certainty, pinning the former Lord of the Decepticons, Megatron, flat against the cold, polished surface of a massive obsidian study table. Ancient, leather-bound data-slates and delicate holographic projectors trembled with each movement, pushed to the table's edge by the sheer percussive force of it. The soft, ambient glow of archival crystals cast long, dramatic shadows that danced over towering shelves of memory cores, illuminating the scene in a ghostly blue light—and illuminating Megatron's own upturned face, optics wide and glazed over and jaw slack with a thin trail of oral lubricant making its way down a corner.
His processor was running. Trying, at least. Somewhere beneath the cascade of sensation, a desperate subroutine kept firing, reaching for context, for logic, for any framework that could contain this.
But this… this was beyond comprehension. This was delirium.
A particularly sharp thrust ripped a sound from his vocalizer, "Nnngh—Aaahhnngh!", a raw, static-laced cry that was half protest, half something else entirely. He wasn’t in pain, no. His armor, though no longer built for war, was still formidable transformium. It could withstand this. It was withstanding this. The sensation, however, was a system shock of an entirely different order, a cascade of overload signals flooding his neural net with each deep, grinding, perfectly angled thrust. His world had narrowed to the hot, searing point of connection, to the overwhelming weight and heat of Optimus above him, and to the frantic, glorious scramble of his own consciousness trying to compute a path through the madness.
How? The question burned through his processor, a desperate firewall against the rising tide of sensory data. By the Pit and all its smelters, how did I get here?
***
The path to confusion, as it so often did for Megatron these solar cycles, began not with a declaration of war, but with a search for a vanished verse.
The Hall of Echoing Epics was the quietest wing of the newly restored Iacon Archives. Its ceiling soared into darkness, its shelves—carved from luminous crystal and recovered steel—held not tactical reports, but poetry, drama, and philosophical transcripts from before the Golden Age. It was a place for ghosts and scholars. Megatron, who was a little of both, had claimed a secluded nook as his own.
He was trying to write. The act felt as foreign and delicate as reassembling a shattered crystal goblet. The forge of his rage was cold; in its place was a hollow, aching space where the fire of his early oratory had once roared. He sought the old words, the ones from the pits of Kaon, before they had curdled into battle hymns. His datapad glowed with a single, stubborn stanza, its rhythm all wrong.
He was still staring at it when a sound broke the deep silence.
It was not the shuffle of another scholar. It was pedesteps. Heavy ones. Unhurried and completely without apology. The measured clanks of someone who could move with ghostly silence but had chosen, pointedly, not to. Each pedefall landed with the full, settled weight of a mech who owned whatever ground he stood on, and wanted the very stones of the archive to announce his arrival.
Megatron did not look up. He knew that cadence. He had tracked it through the smoke of a thousand battlefields. His grip tightened on the stylus.
Optimus Prime rounded the end of his shelf, his approach marked by the careful steadiness of someone entering a sanctum rather than a battlefield. He moved with a quiet purpose, his blue and red armor buffed to a soft sheen, free of battle scoring. His battle mask was retracted. He carried no data-slates. He simply stopped at the edge of Megatron’s table, and his shadow fell over the glowing datapad.
"Megatron.”
Megatron kept his optics on his work. "Prime. The engineering wing is three levels down. I believe they have picture books on bridge construction there. More your speed.”
A soft, almost imperceptible vent of air—the ghost of a laugh. "I am not here for engineering texts. I was told I might find you among the poets.”
That made Megatron look up. Optimus was standing there, his posture relaxed, his servos at his sides. His blue optics were fixed on him with an intensity that had nothing to do with threat assessment. It was…contemplative.
"Who told you that?” Megatron asked, his voice flat.
"Ratchet. He said you’ve been spending all your cycles here, ‘brooding over pre-war iambic pentameter.’ His words.”
"Ratchet should focus on his own corroded circuitry and leave my routines alone.”
"He is concerned. As am I.” Optimus took a single, slow step closer. The space in the alcove suddenly felt compressed, charged. "This is a lonely place for a mech of your energies.”
Megatron leaned back in his chair, a low scoff in his vocalizer. "And what would you suggest? Should I take up a cheerful hobby? Perhaps decorative welding? Or join a glee club with Bumblebee?”
"I would suggest,” Optimus said, his voice dropping into that signature register that seemed to vibrate the polished stone of the table, "that you are not a mech meant for solitude. Not truly. Your power has always been in connection. In moving others.”
"A connection you spent millions of years trying to sever.”
"A connection I never understood,” Optimus countered, and he took another step. Now he was at the side of the table, close enough that Megatron could see the fine seams in his facial plating, the faint pulse of light in his chest. "I saw only the destructive force of it. I failed to see the magnetism. The artistry.”
Megatron felt a strange, hot flicker in his spark. He dismissed it as irritation. "Is there a point to this literary criticism, Prime? Or are you merely bored with peace and seeking to annoy me as a pastime?”
Optimus did not rise to the bait. Instead, he reached out and tapped a single, blunt finger on the datapad’s screen, right over the flawed stanza. "This line. The scansion is off. You have a trochee where you need a spondee. It’s making the verse stumble.”
Megatron stared, utterly dumbfounded. Of all the things he had expected—a lecture, a veiled threat, political maneuvering—this was not on the list. "…You are correcting my meter?”
"I am familiar with the works of Solonus,” Optimus said, as if discussing energon grades. "His Requiems for a Broken Sky were required study in the Hall of Records. Your attempt echoes his early style, but you are forcing the rhythm. You need to let the weight of the words land.” His finger slid slightly, indicating a different stress. "Here.”
Megatron’s engine gave a low, baffled rumble. "The Hall of Records. You would cite your filing clerk’s education to me?”
"It was not a ‘filing clerk’s education’,” Optimus replied, his tone still measured, but a hint of dry pride bleeding through. "It was archival stewardship. I was responsible for the authentication and preservation of the entire Cybertronian poetic canon from the Manganese Period onward. I have held Solonus’s original wax-tablet fragments in my servos. I know the precise chip on the edge where he scored out a failed line.” He tilted his helm and dropped his gaze back to the datapad. His focus was so absolute it seemed to silence the very air around them. "Your error is a common one. Most modern translations standardize the glyphs, which erodes the original cadence. You are, essentially, reciting a perfect copy of a flawed translation.”
He finally looked up, and the ghost of a smile touched his mouthplates—a knowing, intimate little curve, as if they were co-conspirators in a grand and dusty secret. "Consider this less a correction from a fellow warrior, and more a…peer review. From a former colleague of the poet’s keepers.”
The expression, coupled with the staggering depth of esoteric knowledge, did something strange to Megatron’s internals. A low, subtle heat pulsed once, deep in his chassis, a phantom ignition of something that had no business sparking in the heart of a library, directed at Optimus Prime. It was the thrill of being seen in a way he hadn't been in millennia: a scholar who had made a specific, forgivable error. It was an intimacy more profound than a punch, a shared language in a room full of ghosts. He shoved the sensation down, burying it under layers of cold suspicion, but his vocalizer still locked for a moment, his processor scrambling.
"Why are you here?” he finally managed, the question stripped of its earlier venom, replaced by pure, unadulterated confusion.
Optimus’ optics brightened with that same terrifying, focused calm. But now Megatron could name it. Certainty. It was the calm of absolute certainty.
"Because you are the most compelling subject I have ever studied,” Optimus said, his voice low and unwavering. "And I have read every archive in this city. I know the shape of your rage, the architecture of your ambition. I have memorized the patterns of your battle strategies like epic poems.” He leaned forward, bracing his servos on the table, caging Megatron in without touching him. The warmth of his engine wash brushed against Megatron’s plating. "But I do not know the rhythm of your peace. I do not know the verse you write for yourself, when no one is listening. I wish to.”
It was the most blatant, audacious thing anyone had ever said to him. A challenge. It was a challenge to a conversation. It was dangerous.
Megatron found himself standing, his chair scraping back. Sitting felt suddenly untenable. "This is absurd. You are speaking nonsense. Go and ‘study’ someone else. The war is over. We have no more business with each other.”
"You are wrong,” Optimus said, straightening to his full height, his presence filling the alcove. "The war was our business. This is something else entirely.” He gestured to the datapad. "You are trying to build a new verse from the rubble of the old. A difficult task. It requires a different kind of strength. A receptive strength.”
He took one final, decisive step forward, erasing the last of the polite distance. He was close enough now that their armor nearly brushed. Megatron could see the fine etchings around his optics, could feel the steady and inviting electromagnetic field he emitted.
"I have strength to spare, Megatron,” Optimus murmured, the words meant for his audials alone. "And I find I am receptive.”
The implication hung in the air between them, thicker than smoke, more tangible than any hologram. It was an offer. A proposition. Wrapped in literary critique and delivered with the gravity of a state treaty.
Bold.
Megatron’s processor spun. Every instinct screamed to shove him away, to call him a sentimental fool, to retreat into the familiar fortress of his bitterness. But another part, a part he had thought long dead, stirred. The poet. The mech who understood the power of a perfectly chosen word, of a rhythm that could move sparks. And Optimus Prime had just composed a line that resonated in his very core.
He said nothing. And his silence was a stunned, vulnerable aperture.
Optimus saw it. He always saw the critical weakness. And he moved.
One large, sure servo came up to cradle the side of Megatron’s jaw, the touch startling in its gentleness. The other settled on his hip, a firm, guiding pressure. There was no violence in it, only an undeniable, confident intent.
Megatron’s systems flooded with conflicting alerts. He should protest. He should break the hold. Instead, he felt his own servo rise, as if of its own accord, and come to rest on the Prime’s armored forearm. Not to push away. To steady himself.
Optimus’s gaze held his, a silent question in the blue light.
Megatron, the master of a thousand defiant speeches, found he had no words. Only a static-filled ex-vent. And a slight, almost imperceptible tilt of his helm into that warm, solid servo.
It was all the permission Optimus needed.
He guided Megatron back against the solid, unforgiving surface of the obsidian study table. The datapad clattered to the floor, its light winking out with a flicker. Megatron’s vocalizer produced a staticky crackle—a protest that never formed into words—as the cool, polished stone met his backplates. Optimus leaned into him, the full, heavy weight of him both a shock and a profound relief, pinning him in place not with malice, but with a certainty that felt like gravity itself.
"I have studied you,” Optimus murmured again, his voice a low vibration that thrummed through the metal where their chestplates met. His face was inches away, his blue optics drinking in every minute shift in Megatron’s expression. "Not just your strategies. Your form.”
His servos began to move.
The first touch was to the reinforced seam where Megatron’s heavy pauldron met the complex cabling of his neck. It was a notoriously stiff joint, a chronic point of tension after eons of wielding the fusion cannon. Optimus’s fingers, surprisingly deft for their size, found the exact pressure point where three primary hydraulic lines converged. He pressed, a firm, rolling motion that made a burst of unexpected, dazzling sensation—a deep, releasing pleasure—shoot down Megatron’s arm strut. A choked-off gasp escaped him.
"You… ah! How—?”
"I watched you favor it after the Battle of Kalis,” Optimus said simply, his mouthplates grazing the angled ridge along the side of Megatron’s helm. The contact sent a jolt straight to his core. "You would roll it, just so, when you thought no one was looking.”
He continued his exploration, a cartographer of secret vulnerabilities. His lips mirrored the path of his servos, not with the hard clash of a warrior, but with the soft, seeking pressure of a scholar tracing an inscription. He found the secondary vent cluster beneath Megatron’s jaw, a sensitive heat-exchange array, and exhaled a stream of warm, regulated air across it. Megatron’s helm fell back against the table with a soft clunk, his optics shuttering involuntarily. A low, involuntary thrum started deep in his engine.
"And here,” Optimus continued, his voice now a husky whisper against his audial. One servo slid down the heavily armored plane of Megatron’s side, fingers slipping into the narrow gap between his thoracic plating and his abdominal armor. It was a structural weak point in most mechs, a place to drive a blade. Optimus stroked it instead, applying an oscillating pressure to a bundle of exposed sensory wires that lay just beneath.
Megatron’s entire frame jerked. A sharp, staticky cry, "Ngh!", was torn from him. It was an obscenely sensitive spot, one he had shielded in battle for precisely this reason. Pleasure, white-hot and shocking, arced through his neural net like a lightning strike. His servos, which had been lying stunned at his sides, flew up to grip Optimus’s upper arms, his fingers digging into seams.
"You you’ve been watching,” Megatron accused, his vocalizer thick with static and burgeoning need. "From our fights… you mapped my…my sensors…”
"I memorized you,” Optimus corrected, his own vents beginning to cycle faster, a hot wash of air against Megatron’s neck. His other servo was busy, traveling lower, tracing the formidable interlocking plates of Megatron’s hip. "Every flinch. Every minor shift in your stance to protect a point of overstimulation. I did not understand then why pain and pleasure used the same pathways. I do now.”
His fingers found the first in a series of manual, biometric latches, ancient and largely forgotten access points for deep-system interface, hidden beneath decorative armor flaring. With a series of careful, knowing clicks, he triggered them in sequence. One after another, with the calmness of a safecracker who had long ago deduced the combination.
Click-hiss. A segment of abdominal armor loosened.
Click-hiss. Another slid aside, revealing a patch of glittering, vulnerable inner mechanics and plush, gray protoform.
Click-hiss. A third, along his flank, exhaled open with a pressurized sigh.
The cool, climate-controlled air of the archives washed over the newly exposed complexity, not all at once, but in stages, each breath of cool air landing on a different, newly bared patch of Megatron's chassis. A network of shimmering energy conduits. Sensitive hydraulic lines. Clusters of sensory wiring and protoform that had never, in four million years of war, been left unguarded.
Megatron felt a wave of dizzying exposure, hotter than any shame.
Optimus drew back just enough to survey his own handiwork, his optics blazing with a reverence that was almost religious. "A masterwork," he breathed.
He started at Megatron's chest.
His helm lowered, and his intake found a major sensory conduit running along the left pectoral plate—a thick bundle of wires sheathed in bioluminous insulation, faintly lavender in the archival dark. He kissed the length of it, a slow, dragging press of metal lips that made Megatron jolt. Then his glossa followed, tracing the individual wires, teasing them apart with slick, precise flicks.
"Ah—! Frag—!" Megatron gasped, his back arching off the table. The sensation was a direct, unmediated feed into his pleasure centers.
Optimus hummed against the bundle, the vibration traveling through the wires and straight into Megatron's core. Then he lifted his helm and moved on.
His lips found the next cluster lower, tucked into the curved recess beneath Megatron's left pectoral, where the armor thinned over a dense weave of data-transfer lines. Finer wires, these. More numerous. Optimus separated one with his thumb and forefinger, rolling it with exquisite pressure, then bent and drew the delicate tip into his intake with a soft, wet sound.
Megatron made a noise he would later refuse to acknowledge. His servos flew up, fingers scrabbling at Optimus's helm, not pushing, just holding and anchoring himself to something solid as his sensory net lit up like a signal flare. His valve, still sealed behind its final plating, clenched down on nothing.
"So my schematics thhen?" he managed, his voice shredded with static.
"I studied you," Optimus murmured, releasing the wire with a soft pop. He pressed a slow, open-mouthed kiss to the protoform beneath it, gray and warm and terrifyingly soft, before lifting his helm again. His optics found Megatron's, briefly, burning with focused intent. Then he moved lower.
His servos preceded him, palms flat against the planes of Megatron's abdomen, thumbs mapping the gaps between armor segments with the patience of an archivist handling something irreplaceable. He found the sensory cluster along Megatron's right flank—a dense texture of exposed wiring that ran along the inner seam where his hip plating began—and stroked it, a rolling, oscillating pressure that sent a lightning strike of sensation up Megatron's spinal strut.
"Ngh—!" Megatron's entire frame jerked. His fingers tightened on Optimus's helm.
"Every twitch," Optimus said, his voice dropping lower as he pressed his lips to the flank cluster, tracing the wiring with his glossa in measured passes. "Every spark of feedback when a shot grazed a specific zone. It was all data. A biography written in neural impulses." He lifted his helm, his breath a hot wash against sensitive cabling. "I simply never had permission to read it properly."
He moved lower still.
The wiring thinned here, near the lower abdomen, the conduits spreading outward toward the hips like the roots of something ancient. Optimus followed them with his fingertips, unhurried, tracing each line to its terminus. His lips skimmed the exposed protoform in the gaps between, warm and deliberate. Megatron's vents were cycling hard now, his chassis rising and falling in ragged increments, his sensory net a sprawling, overwhelmed map of contact points.
Then Optimus's servos settled at his hips. And stilled.
The stillness was worse than movement. It was the held breath before a word lands.
His fingertips found the trigger, a small, recessed node nestled at the confluence of the lowest conduits, directly above the valve housing. He did not press it immediately. He simply rested his thumb against it, a warm, unmoving weight, and looked up the long plane of Megatron's chassis until their optics met.
A silent question. The same one as before.
Megatron's vocalizer produced nothing useful. Only a long, staticky ex-vent. And the faint, helpless lift of his hips toward that unmoving thumb.
Optimus pressed it. A firm, rolling caress.
There was a final, wet, hydraulic shunk-click.
The last shield retracted.
And there it was.
The cool archival air met it first, a soft, collective intake of the climate system that felt, absurdly, like the room itself acknowledging what had been uncovered.
Megatron's valve was nothing like the brutal, functional architecture of war. It was a stunning, intricate bloom of layered, flexible proto-metal petals, glossy with lubricant, biolights glowing that same soft, internal lavender from within—the same faint light that had threaded through his wiring, now concentrated here, pulsing with the rhythm of his spark. The petals were arranged in a mesmerizing, concentric pattern, each layer slightly more delicate than the last, leading inward to a tightly clasping entrance that already fluttered with small, involuntary contractions. Above it, his spike housing remained sealed, but the prominent, heavy outline pressed urgently against its armored plate.
Optimus went utterly still.
He’d just opened a text he had spent his entire life trying to find, and needed a moment before he could bear to read it.
His vents caught. Reset. Caught again.
"Oh," he exhaled, the word barely a sound. His optics were wide, unshuttered, drinking in every detail with an intensity that felt more exposing than the open air itself. "Megatron." A pause, long and reverent. "It's exquisite."
The praise, so raw and unguarded, sent a wave of heat crashing through Megatron from his core outward. He had been called many things. Powerful. Terrifying. Worthy. Never that. His fingers curled against the obsidian surface beneath him, seeking purchase.
Optimus lowered his helm.
He did not go immediately to the entrance. He pressed his lips, instead, to the outermost petal—the barest, softest contact, a greeting more than anything else. Then the next. Working inward with the same slow, cartographic patience he had applied to every other part of Megatron's chassis, learning the texture of each layer, the way the proto-metal gave slightly under pressure, the way the biolights brightened fractionally when he lingered.
Megatron's helm fell back against the obsidian with a soft clunk, a sound of pure, structural surrender. A low, broken sound escaped him fully without his permission.
Only when he had mapped the outermost architecture did Optimus's glossa make contact with the entrance itself in a single, slow drag upward across the tightly clasping center.
"Fra-a-ag." The word tore out of Megatron in a burst of static. His hips pitched upward, chasing the contact before he could stop them. His entire valve clenched in response, a slick, rhythmic flutter, lubricant welling freely now, catching the low light.
Optimus made a low sound against him, a deep and unhurried rumble of satisfaction. He did it again.
"You know exactly where to—" Megatron's sentence collapsed as Optimus's glossa found the cluster of hyper-sensitive nodes just above the rim, applying a firm, rolling pressure that sent white static blazing up his spinal strut. "Frag—there—"
"I know," Optimus said, his voice a husky rumble against the most sensitive architecture of Megatron's chassis. He lifted his helm just enough to speak, his breath a devastating wash of warm air across the exposed array before he repeated the slow, tortuous circuit. "Tyger Pax. A ricochet from Ironhide's cannon. It struck near." He pressed the flat of his glossa firmly against that specific node. Megatron's back arched clean off the table. "Your left guard dropped for 0.3 kliks. I could not understand why such a minor hit caused such a critical lapse." A pause, weighted with dark satisfaction. "Now I do."
The clinical history, delivered against the most vulnerable part of him, was more devastating than any poetry. Megatron cried out, a broken, static-laced sound that echoed off the towering shelves. His valve clenched rhythmically, desperate, lubricant slick against Optimus's lips. "Enough. Enough forensics—"
Optimus hummed. Continued his circuit.
"Prime." His name, this time, came out wrecked and imperative in equal measure.
Optimus lifted his helm. His glossa gave one last, slow, flat lick from the bottom of Megatron’s dripping valve all the way up to the throbbing anterior node, making Megatron’s struts shudder. His optics softened, a sweet, knowing light in the blue. He pulled back just enough to make the cool air sting the wetness he’d painted there, his voice a low, flirtatious murmur. "The data is compelling. But the subject is reticent. Poets should be better with words. Tell me what you want, Megatron. Let me hear the verse.”
The gentle chiding, the literary callback, was its own exquisite torture. Megatron’s pride warred with the molten need pooling in his array. He ground his hips down in a futile chase after that wicked, retreating intake. "You insufferable…archivist…!”
"Yours,” Optimus agreed softly. He rose up on his knees, his shadow falling over Megatron completely—even in the dim light. One servo remained on Megatron’s hip, pinning him with gentle insistence, while the other wrapped around the base of his own spike, guiding it through the slick mess he’d made. The broad, wet head nudged forward, a hot, promising tease against the soaked folds. "Now. The word. One clear, poetic word.”
The last of his resistance crumbled into dust. "Now,” Megatron commanded, the word a raw, desperate scrape of sound. "Optimus…now.”
The sound of his given name, spoken not in hatred but in need, seemed to stun Optimus for a nanoklik. His expression shifted from playful to something fiercely tender, almost reverent. "At last,” he whispered.
He didn’t slam home. That would have been too simple, too brutish. This was Optimus Prime. He aligned himself with what Megatron could best describe as an infuriating slowness. The blunt, slick head of his spike claimed Megatron’s entrance, spreading the glossy petals wide with an undeniable, gradual pressure. He paused there, sheathed just an inch, savoring the tight, clenching welcome, the way Megatron’s entire frame trembled with suspended, aching need.
Their optics locked. No more words. Just the silent, charged understanding of a long-denied verse finally being written.
Then, with a single, powerful, inexorable roll of his hips, Optimus sheathed himself.
The stretch was immense, perfect, devastating. Megatron’s helm slammed back against the obsidian, a raw, guttural roar tearing from him as every ridge, every thick, unforgiving inch, filled him completely, bottoming out with a deep, resonant clunk of pelvic plating meeting pelvic plating. It was a fit so shockingly right it felt less like an invasion and more like a homecoming to a place he’d never known he’d lost. The sensation was a full-system overload, a blissful, white-hot short-circuit that burned away the last ghost of his resistance.
Optimus froze, buried to the hilt, his own vocalizer producing a choked, reverent groan. His optics were wide, unshuttered, his face a mask of stunned awe. For a long, shuddering moment, they were simply joined, fused, the only sounds their ragged vents and the wet, intimate sound of connection.
"Beautiful,” Optimus whispered, the word a prayer of discovery.
Then he began to move.
A lingering withdrawing drag that made every sensor in Megatron’s valve sing a mournful note at the loss, followed by a relentless, rolling thrust that seated him deep once more. Clunk. Shhhk. Clunk. The rhythm was methodical, concentrated, each stroke a crisp impact that drove the air from Megatron’s intakes in punched-out gasps.
"You… you mapped my insides, too,” Megatron accused, his voice wrecked, as a ridge passed over a deep, internal cluster of nodes with pinpoint accuracy, lighting up his HUD with pleasure alerts.
"I hypothesized,” Optimus grunted, his own composure beginning to fray at the edges into something warmer, more eager. His pace increased incrementally, the smooth rolls turning into sharper, deeper drives. The slapping sound of their plating joined the rhythm. "From the way you… ah… the way you moved. Your combat form… it suggested internal symmetries.”
Another thrust, angled perfectly. Megatron saw static. His servos scrambled against Optimus’s back, claws catching on transformation seams to hold on. "You… sentimental… fool…”
"For you,” Optimus gasped, and finally, finally, his sweet control cracked into something hungrier. His thrusts lost their measured quality, becoming powerful, driving, possessive. He leaned down and brushed his lips against Megatron’s jaw, his vocalizer buzzing against the metal. "Only for you. My most fascinating text.”
Megatron was unraveling. The pleasure was a riptide, pulling him under. Each thrust struck a chord of bliss so deep it felt like dying and being forged anew. His valve clamped down, rippling in eager waves around the invading spike, trying to draw it deeper into a core that was turning molten. His own spike, still pressurized and trapped in its housing, throbbed in time with the pounding rhythm, begging for a touch that never came. He was babbling, a stream of static-laced fragments—old Kaonite curses, half-remembered lines of pre-war verse, and the soft, punched-out repetition of ”Optimus… Optimus…”
Optimus was murmuring into his neck, a sweet, relentless counterpoint to the driving pace. "I have you… my brilliant, furious poet… I finally understand… you feel like coming home…”
The tenderness within the possession shattered him completely. His overload began as a cresting wave, rising from the depths where they were joined. It swelled, undeniable, until it broke over him with a silent, dazzling force. His frame locked, his valve clamping down in a vicious, rhythmic vise around Optimus’s spike, his back arching clear off the table as a torrent of charge, bright and blinding, erupted through every circuit in a cascade of sparking, lavender light. His vocalizer blew out into a long, ragged, digital cry of pure, overwhelmed ecstasy.
Feeling the violent, fluttering contractions, Optimus gave one last, deep, shuddering thrust and followed him over. His groan was muffled against Megatron’s shoulder, a raw, unfiltered sound of completion and wonder, as his own hot transfluid flooded Megatron’s depths, triggering secondary, smaller aftershocks that made Megatron tremble uncontrollably against him.
The silence that followed was heavy and sweet, broken only by the syncopated whirr of their cooling systems and the slow, steady drip of fluids onto the archive floor below.
Optimus slumped over him. His weight was a solid, anchoring warmth. He nuzzled gently at Megatron’s neck cables, his vents hot against sensitive wiring. Megatron, pinned and utterly spent, could only stare up at the distant, dark ceiling of the Hall of Echoing Epics, his processor a blank, humming slate.
The question echoed in the new quiet, more insistent than ever.
How did I get here?
No answer came. Not in words, not in echoes. Only the intense, irrevocable silence of a question that had, at long last, become more important than any answer.
***
Time, which had condensed into a single, white-hot point, began to dilate again. The first sensation to return was the liquid warmth pooling in his lower chassis, a tangible reminder of the violation that had felt like a benediction. Then came the weight—the glorious, crushing weight of Optimus Prime, in a state of complete and total repose upon him.
Optimus’s vents were beginning to slow, cycling from ragged gulps to deep, even draws. The servo that had been braced against the table shifted, sliding up to cradle the side of Megatron’s face. The touch was so unbearably gentle it made something in Megatron’s spark chamber constrict.
"Megatron?” The name was a soft puff of air against his audial.
He couldn’t answer. His vocalizer felt scorched, his linguistic processors scattered. He managed a grunt, a low, affirmative rumble from his chest.
A soft ex-vent, one that might have been a sigh of relief or contentment. Optimus began, with infinite care, to withdraw.
It was a different kind of intimacy. The glide out was slow and sensitive, a reverse pilgrimage that made every overstimulated sensor twitch and flutter in a final, weak chorus. A fresh trickle of transfluid, now mixed with lubricant, escaped the seal as the connection broke with a soft, wet sound. Megatron’s valve, feeling suddenly empty and too-large, gave a feeble, clenching pulse.
Optimus settled back, his own plating re-sealing with a series of soft clicks and hisses. In the low light, his face was soft, his optics dimmed to a gentle azure glow. He looked… young. Unburdened.
His gaze fell to the mess between them, then to the small, gleaming puddle that had spread from beneath Megatron’s aft on the table to the polished floor. Without a word, he reached for the fallen datapad. Its screen was dark, cracked surely from the impact. He set it aside, then did something that stunned Megatron more than the interface itself: he retrieved a soft, woven cloth from a subspace pocket. It was a polishing rag, the kind used for delicate console screens. He began to clean.
He started with Megatron, his touch methodical and tender. He wiped the residual fluids from the trembling petals of his valve, the cloth absorbing the evidence of their union softly. His fingers, so precise and knowing minutes before, now worked with a nurse’s care, checking for any sign of abrasion or strain. The humiliation should have been volcanic. Instead, Megatron felt a strange, passive awe. He could only watch, his head still resting against the cold obsidian, as the mech he had tried to annihilate for four million years ministered to him.
Next, Optimus attended to himself, a quick, efficient routine. Finally, he knelt and wiped the floor, erasing the damning puddle until only a faint, damp sheen remained. He folded the cloth, stained with their mingled essences, and stowed it back in his subspace. A souvenir. An archive.
The silence stretched, but it was no longer charged with hunger. It was thick with something else. Something vast and unspoken.
Optimus stood and offered a servo. Megatron stared at it. It was the servo that had held the Matrix. The servo that had wielded the Star Saber. The servo that had just mapped his pleasure with devastating accuracy. He took it. The grip was firm, pulling him up to sit on the edge of the ravaged table. His legs felt unreliable, his gyros subtly misaligned.
"Are you…” Optimus began, then seemed to search for a word less clinical than ‘functional’. "…Are you intact?”
Megatron looked down at his own servos, resting on his thighs. He flexed his fingers. "My systems report no critical damage. Only a… comprehensive re-prioritization of sensory input protocols.” He finally looked up, meeting Optimus’s gaze. The flirty archivist was gone, replaced by someone whose calm ran even deeper. "You have vandalized a historical artifact,” Megatron stated, gesturing vaguely to the table. "I believe you have permanently altered the structural integrity of this slab.”
A soft, real chuckle escaped Optimus. It was a warm, rich sound Megatron had only heard in propaganda holos from before the war. "A worthy sacrifice,” Optimus said, his optics crinkling at the corners, "for the data acquired.”
The joke, their shared, terrible joke, hung between them. Megatron found his own mouthplates trying to twitch into something that wasn’t a snarl. He looked away, his gaze landing on the blank, cracked datapad. "My verse is still flawed,” he muttered, the non-sequitur escaping him. "The spondee remains elusive.”
He felt Optimus move closer. They were not touching, but his field, warm, electric, and now softly content, washed over him. "We could workshop it,” Optimus said, his voice low. "I am… free tomorrow evening. My usual archival review is hardly pressing.”
An invitation. To converse. The mundanity of it was terrifying.
Megatron pushed himself off the table. His struts held. He took a step, then another, away from the alcove, into the main aisle of the hall. The towering shelves of memory cores seemed to watch, silent witnesses. He heard Optimus’s heavy pedesteps fall in behind him, accompanying.
They walked through the Hall of Echoing Epics in silence, their pedefalls the only sound. The space between them, which had been reduced to nothing, now felt like a new kind of field—tentative, magnetic. As they passed a junction, Optimus’s servo came up, his fingers brushing the small of Megatron’s back to steer him gently away from a forgotten stack of data-slates left on the floor. The touch, so casual and proprietary, sent a fresh, quiet jolt through Megatron’s systems.
They emerged from the archives into the vast, vaulted Grand Concourse of the Iacon Central Library. Here, the silence was of a different quality, cooler, more public. The only light came from the massive, crystalline windows, where Cybertron’s twin moons, Phelan and Trion, cast intersecting silver beams that cut through the dust motes in the still air. The shattered spires of the city were silhouettes against a star-flecked indigo sky, many still scaffolded, being rebuilt.
Optimus led them away from the main exist and towards to a lesser-known side archway that opened onto a narrow, exterior balcony. The night air was crisp, carrying the distant hum of construction nano-drones and the faint, ozone-tinged scent of a healing world.
Megatron went to the railing, gripping the cold metal. He needed the solidity. Below, the geometry of a reborn Iacon spread out in a beautiful and strange lattice. Optimus came to stand beside him, close enough that their arm plating almost touched.
"What was that, Prime?” Megatron asked the city, his voice flat. "A final act of domination? A scholarly experiment in post-conflict spark resonance? A pity-frag for the deposed tyrant?”
He felt Optimus turn to look at him, but he kept his gaze forward.
"It was a ceasefire,” Optimus said, his voice quiet but clear in the night air. "The only one that ever mattered.”
Megatron scoffed, a weak sound. "Ceasefires are negotiated. They have terms.”
"The terms are simple,” Optimus said. He leaned his forearms on the railing, mirroring Megatron’s posture, a commander off-duty. "No more weapons pointed at each other’s sparks. Only observations.”
"Your observations are intolerably intimate.”
"They are the only ones I have left that hold any interest.” Optimus was silent for a long moment. "When we buried the AllSpark shard, when the last treaty was signed, I asked myself a question. ‘What remains when the war is gone? What is the purpose of Optimus Prime without a Megatron to fight?’” He turned his helm, and Megatron was forced to meet his gaze. The blue light was solemn. "You remain. As a fact. The single most significant fact of my existence. I do not know what to do with that fact, now that I am allowed to look at it without aiming a blaster.”
The raw, unvarnished truth of it sent a zip of feeling up Megatron’s spinal strut. It left him breathless. He had asked himself a similar, inverted question in the depths of his cell: What is a hammer without a nail to drive?
"So you decided to fragging study it,” Megatron said, the crude word a shield.
"I decided,” Optimus corrected gently, "to read it. To see if the text, when removed from the context of war, said anything new.” A faint, sad smile. "It does. It is beautiful, and angry, and full of stunning, flawed meter.”
With faceplates suddenly swarmed with heat, Megatron looked away, back at the city. His city. Their city. "I do not know how to be… this. A fact. A subject of study. A poet with a faulty spondee.”
"You do not have to know,” Optimus said. "We can learn. Together. As we learned to fight one another. With the same focus, but toward a different end.”
"And what end is that?”
"I do not know that either,” Optimus admitted. He straightened. "But I would like to see you again. Outside of council chambers. Outside of this library. To continue the conversation.”
The invitation, restated, hung in the lunar light. Megatron cycled a vent, cool air washing through his internal heat. The part of him that was still smarted when he recollected his own history screamed to reject it, to retreat into the familiar, comfortable fortress of isolated bitterness. But that fortress felt like a tomb now, with its walls paper-thin. Especially now.
He turned his helm to return his gaze to Optimus, to meet the solemn blueness of those optics, and to voice another deflection, another shield of sarcasm. But his vocalizer stalled.
Optimus was just… looking at him. His gaze dropped, for a fleeting nanoklik, to Megatron’s lip-plates. Then, tentatively, Optimus’s own lip-plates parted. His glossa darted out, a quick, wet flick to moisten them, a nervous gesture Megatron had never seen from him. The moonlight caught the subtle sheen it left behind.
The sight sent a bolt of pure, illicit heat straight to Megatron’s array. An intrusive, unbidden thought flashed: Kiss. I want--
He shoved the thought down violently, his cooling fans threatening to click on. Before he could give voice to any of the chaos in his processor, anger or denial or a shocking surge of want, Optimus spoke. His voice was a low, rough murmur that danced in the cool air between them.
"May I?”
The request was so simple, so devastatingly honest, it stole the air from Megatron’s intakes. It wasn’t a demand or a ploy. It was a request for a new kind of access. Megatron couldn’t speak. He gave a single, stiff, almost imperceptible nod.
Optimus closed the scant distance between them. There was no hesitation now. One servo rose to cradle the side of Megatron’s face, his thumb stroking once, gently, over the seam of his cheekplate. The other settled on his hip.
Then he kissed him.
It started soft, a reaffirmation of the closed-mouth press from his fantasy. But it didn’t stay there. Optimus’s lips moved against his, coaxing, asking. After a stunned moment, Megatron’s own intake softened, yielding. A vent hitched between them. Optimus’s glossa traced the seam of his lips, a silent, hot question, and with a groan he didn’t mean to release, Megatron opened for him.
The kiss deepened, turning slow and passionate. It was a mapping of a different territory, an exploration just as meticulous. Optimus tasted of clean energon and the faint, ozone-tinged night air, and underneath it, something uniquely, intimately Optimus. Megatron’s servo came up, tangling in the cabling at the back of Optimus’s neck, pulling him closer. The balcony, the city, the war—all of it dissolved into the heat of the intake moving against his, the slick slide of glossa, the soft, wet sounds of their shared breath.
It was building, shifting. The servo on Megatron’s hip slid lower, gripping with a familiar, possessive pressure. Optimus pressed him back gently against the cold railing, the heat of his frame a brand. The kiss turned hungrier, deeper, a direct conduit to the embers still glowing in Megatron’s lower chassis. It was a prelude. A promise of a second, slower, well considered round right here against the balcony, under the twin moons.
The realization was a bucket of ice on his smelting core.
With a ragged, static-filled gasp, Megatron tore his intake away. He shoved against Optimus’s chest, not hard, but with enough force to break the contact. He stumbled back a step, his vents roaring to life in a loud, desperate whirr, cycling air he couldn’t seem to get enough of. His lip-plates felt swollen, sensitive. His entire face was on fire.
Optimus stood where he was, his own vents audible, his optics dark and wide. A thin string of lubricant connected their intakes for a second before breaking.
"Your sentimentality,” Megatron rasped, the words scraping out of a dry vocalizer, "is a critical weakness, Prime.” The insult was pure reflex, utterly hollow. "It will be your undoing.”
Optimus’s smile was shaky, his gaze locked on Megatron’s kiss-bruised intake. "Noted.”
Megatron turned and strode back through the archway without another word, into the shadows of the concourse, his frame humming with denied charge and the haunting, perfect memory of the kiss. He did not hear Optimus follow. But the ghost of it lingered on his mouthplates, a brand far more intimate than anything that had come before.
He walked away, into the dark, the taste of Optimus still on his glossa.
***
The walk to his quarters was a blur. The guards at the residential sector nodded, their optics flicking over him with routine disinterest. He keyed his door open, stepped into the dim, utilitarian space, and let it seal behind him.
Only then, in the absolute privacy of silence, did he allow himself to process.
He walked to the small, clear panel that served as a window, looking out at the same moonlit vista from a different, lonelier angle. He raised his servo, the servo that had gripped Optimus’s back and that had clawed for purchase, and stared at it.
Slowly, he brought his fingers to his own intake. His lip-plates were tender, slightly swollen from the pressure. He traced the line where Optimus’s glossa had sought entry, then let his fingertips drift down the line of his jaw to the spot where Optimus’s lips had first brushed him after claiming him in the archives—a dual-point memory of possession and request. He could still feel the phantom heat of the kiss, the slick, searching slide, and underneath it, the deeper buzz of the vocalizer that had murmured his name against his metal. The combined memory was so vivid his cooling fans kicked on with a soft whirr.
How did I get here?
The question no longer burned. It hummed, a low, persistent frequency in his spark.
He had followed a line of poetry into the dark stacks, and had been checked out by the only other living soul who could possibly understand the reference. He had been read, annotated, and then kissed with a tenderness that felt like a superior kind of violence. It was a footnote that had swallowed the entire text and demanded a rewrite.
He was not okay. He was not fixed. He was, for the first time in eons, interested. And terrified.
A soft ping echoed in his internal comm. A priority, encrypted line. Not the council’s frequency. A personal one, newly registered.
The message was text-only, a string of glyphs in an ancient, pre-war scholarly dialect.
::The structural integrity of the obsidian slab has been added to my report. The data, however, was worth the compromise. I look forward to further collaborative research. 19:00 cycles. Hall of Echoing Epics. Do bring your stylus. - O.::
Megatron stared at the glyphs. He did not reply. But he felt the strange, unfamiliar twitch in his mouthplates again, the one that wasn’t a snarl but was an echo of the kiss he couldn’t forget.
He had until 19:00 cycles to fix his spondee.
He went to his desk, powered up a fresh datapad, and began to write. The first glyph he typed was smudged, his servo unsteady. He deleted it. He started again, the memory of a glossa tracing his lip-seam a persistent, distracting muse.
