Becoming Prime

This Chapter is very dark and for me quite sad. My first proper non-con too so please be kind.
Megatron's dark nature will be explained in another story. A prequel to this one. At a later date.

Chapter 2 – Obedience
Optimus composed himself before entering the central council chambers. He walked steadily trying to shake the screams from his mind. He passed a few council members and managed to nod courteously to their slight bow. Despite having been Prime for some time now being bowed to simply wasn’t something he was ever going to get used to.
Lost in his own thoughts he turned a corner and almost collided with a mech roughly his size. He mumbled his apologies before trying to continue, a firm hand on his shoulder stopped him, he looked up.

“Optimus you’re off in your own world today, I have been looking for you.”
Optimus smiled at the mech, his friend. “Ultra Magnus, I was just, I have been busy today.”

“Ah, Megatron being a slave driver again?” Optimus’s capacitor ticked over at the irony of the comment and could merely muster a shrug. “Optimus are you ok?”
Ultra Magnus having known Optimus since before he was Prime was the only other mech besides Megatron who did not refer to him by his title. Optimus sighed wearily. “I’m fine, really, just need to recharge.”

“I understand.” Ultra Magnus frowned. “What happened to your face?”
“Excuse me?”

Ultra Magnus traced his fingers along the face plates lining his cheek. “They’re scratched.” Optimus drew his hand up. “Oh.” He thought frantically for something to tell him, if it was made public that Megatron had dared to strike him, he could be removed from his position by the council. Cybertron could only be ruled by a Prime, the Lord High Protector was meant to be the guardian of the planet and of its leader. “It’s nothing.” He stated meekly. Ultra Magnus laughed. “Not watching where you’re going?” Optimus managed a thin smile and nodded. “I have to go Ultra.” Ultra Magnus nodded. “We will catch up soon Optimus.” Optimus barely responded as he continued down the corridor. Ultra Magnus watched him go, frowning, he’d known him for a long time and had rarely seen him rattled. ‘I should speak to Megatron about this.’ He thought to himself, Megatron would know what to do; he was the closest to the young leader.

Optimus headed towards his living quarters, they were on the same corridor as Megatron’s. He found himself circling round dark thoughts in his head. He paused for a moment at his own door before moving past it, coming to a stop outside Megatron’s room. Keying in his code swiftly he stepped inside.

’I cannot believe I’m doing this.’ He thought, shame filling his circuits. ‘I should trust him.’ Nevertheless something was bothering him and Optimus was not one to rest until he’d come to the bottom of it. Drifting over to Megatron’s personal console, he picked out the last files downloaded. The face of the prisoner blew up on screen, Optimus’s capacitor skipped. Forcing himself to watch the data track, he was filled with horror and revulsion by the carnal acts the ‘bot had carried out. Just as Megatron had said he had. Exhaling air he sat in Megatron’s chair heavily dropping his head with relief. Guilt washed over him now, why had he questioned him, although he didn’t agree with his methods he’d never given him any reason not to trust him. His optics glanced up slightly catching site of an additional report attached to the file. Frowning, curiosity getting the better of him, he clicked it. A medical report.

Senior Medical Report.
Date: 223.12.904.6
Subject 32957: Personality subroutines are corrupt. Possibly due to a downloaded virus or a simple cascade failure of the cortex. Re-programming to be carried out, when the order is given.
Date: 223.12.904.7
Addendum: Re-programming successful. Subject sent to correctional facility for rehabilitation.
Optimus stared in horror at the date. That was over two cycles ago. He’d been reprogrammed, the ‘bot had technically been innocent. He would have had no memory of his past crimes. His head fell to his hands, nausea built up in him as he felt the back wash of energon in his throat. Gripping the desk he forced himself to stand. He downloaded the file and rushed off to the medical bay. Leaving Megatron’s door unlocked.
****
Having had the report corroborated by the Chief Medic Ratchet, Optimus walked in a daze. How could Megatron have done this? He mustn’t have known. He wouldn’t have continued with the punishment if he’d known. He sat at his own desk, tapping lightly on his console. Keying in a sequence of numbers, another face appeared on the screen. The ‘bot in the locked room. He had indeed off lined someone, quite viciously too. Optimus scanned the file quickly. There it was the medical report staring at him. He opened it reluctantly. Re-programming, successful. He read and re-read the words. The ‘bot had seemed deranged, mad not fit for society. Optimus shook his head, his expression changed to one of determination. He was going to put a stop to this. If there was one decent worthwhile thing he could do as Prime, he was going to do this.
****
Optimus lay in his recharge berth unable to shut down. He had made the order and ensured that the correctional facility had been shut down and locked. The inmates, of which there was more than previously thought trailing into double figures, had been placed under medical supervision and care. Some could be rehabilitated others simply would need care and could never again function in society. The whole process had taken many cycles, leading into a quarter of a solar cycle. Optimus had not realised how long it would take to approve his command and ensure that it was legally carried out. Everything had to be approved by the council unanimously and that always took time. Optimus had not seen Megatron since that lesson. He was concerned, it was normal for him to be called away across the planet to carry out his duties, but still his unnatural silence worried Optimus.

He shuttered his optics trying to relax. His door pinged intrusively. He tried to ignore it hoping they would get the hint. It pinged again. He sat up, now slightly agitated. No one ever disturbed him when he was supposed to be recharging it was considered to be the height of ignorance by the council etiquette.

It pinged once more. “Alright.” He snapped. He went over to the door and opened it. He was greeted by a solid metal fist slamming into his jaw; he staggered back grunting in pain. The door swished closed. “That is for undermining me in front of your chaperone.”
His optics widened. “Megatron? Where have you been?”

“That is not your concern. The fact that I’m here, is.” He leered menacingly, Optimus frowned rubbing his jaw. He moved closer his claws reaching out to touch Optimus’s shoulder gently. “You didn’t trust me.”

“Megatron, I couldn’t let that practise continue. I didn’t mention you at all in the proceedings, it was my order.” Megatron emitted a low grow, his optics half shuttered. Without warning his claw gripped Optimus’s shoulder causing him to wince as the metal in his grasp whined with the strain. He slammed him into the wall his other talon reaching to grip his throat. He did not need to breathe but that did not mean this wasn’t painful. He felt the sharp tips of Megatron’s fingers dig into his neck, scratching the wiring. He gasped at the sensitivity of his own wiring and by the pain that Megatron was causing.

Red optics were now focused unwaveringly on him. “My quarters Optimus. You forgot to close the door behind you.”

“Megatron I’m sorry, unnghh... I needed to know...” Megatron’s hand gripped even tighter causing Optimus to kick his legs out as he felt himself lifting off the floor. “You still don’t trust me.”
“I do, please let me go...” He couldn’t disguise the faint tremble of fear in his voice. Megatron heard it. “You fear me?”
“No, of course I...”

He leaned in closer to his ear finial. “You should.” He whispered softly. Unexpectedly he trailed his golden glossa up the line of Optimus’s ear finial, the young mech whimpered faintly at the touch.

“You will learn Optimus.” He released him, letting him drop unsteadily to his feet. He stared at him intently, Optimus was unsure of what to do or say, he stared back. A flash of something crossed Megatron’s face and he snarled nastily. Launching himself into Optimus they crashed into the wall. Optimus yelped at the force. Megatron held him by his waist tightly. His face was touching his own. Pressing hard on his forehead. Megatron’s optics were shuttered. “I am going to teach you a lesson in obedience Optimus.” He glared at the now tense ‘bot with renewed menace. Optimus could feel heat venting from his face plates. He had no chance to respond.

Megatron planted his mouth firmly, roughly onto Optimus labia plates. He stroked them with his glossa forcing them to part, he could feel the younger mech resisting him, trying to push him away, this only aroused him more. He was going to make this lesson stick. His glossa probed deeply into Optimus’s mouth, finding his own, wrapping around it, caressing it. He felt Optimus groan at the sensation. He tasted good; too long he had desired him. His hands drifted across Optimus’s chassis, sharp fingers probing, stabbing at sensitive wiring lying just need beneath the surface. Optimus jerked and twisted beneath him, trying to pull his body away from the touch. Megatron wondered why he was so resistant. Then his hands stroked across Optimus’s interface port and the mech bucked violently and with a loud angry growl landed his knee squarely into Megatron’s torso, he grunted in pain and staggered back a little.

Glaring at the gasping ‘bot, his optics widened as a delicious thought crossed his mind.
“I’m the first.” He hummed his voice seductive, enticing. Optimus’s optics held his gaze firmly, the look of embarrassment and shock told Megatron all he needed to know. He growled with anticipation.

“Megatron what the frag are you doing?” Optimus managed to speak. “I am teaching you a lesson and also it seems, giving you life experience.” The blue optics narrowed rapidly as Optimus processed his words. Megatron did not like to waste time. He reached out, Optimus ducked but he didn’t react fast enough. Megatron grabbed him by the collar of his armour and threw him bodily into the adjacent wall. Optimus landed with a metallic thud. He was no fighter that was not his purpose. That was why he had Megatron.

Optimus was dazed; he lifted himself onto all fours, his optics struggling to blink online. He tried to push himself off the floor. The large bulk of Megatron slammed into him forcing him to lie flat. Struggling he winced as Megatron grabbed his wrists and pinned them down, he felt the slightly larger mech straddle him. He did not like feeling this vulnerable and liked the thoughts of Megatron’s intentions even less. Megatron’s glossa stroked his ear finial once again; he couldn’t help but moan at the sensation. Pleasurable shivers shot through his cortex. He felt Megatron’s mouth close over the finial his glossa caressing it, he gasped, he didn’t want this, not from Megatron, not like this. He tried to push up as he did so Megatron’s dentals bit into his finial, he cried out with pain. They were so sensitive. He writhed against him, desperate to free himself. He felt heat building deep in his systems, close to his interface port. He willed himself not to get aroused, but his interface module reacted to Megatron’s touches as his talons dug into his back plating, reaching beneath his armour, stroking, nipping caressing.

Optimus cried out as he felt Megatron’s fingers dig deep beneath his plating, grabbing wiring he found beneath it and he tugged it roughly.
“Please Megatron... stop this.” He managed to choke out as he felt his interface module pinging him, sending out desperate signals as Megatron pulled the sensitive wiring even more. Megatron then grabbed both his ear finials and yanked them up hard. Optimus gasped sharply, wincing as the pain shot across his optics. He whispered softly. “You are going to beg me.” He slammed Optimus’s head into the hard floor hard enough to make him off line.

Megatron lifted his weight and stood. His grin all too evident. He gently lifted the limp Optimus and placed him on his berth. Delicately stroking his face plates, he smiled, lust filling his optics. ‘I will wait.’
He did not have to wait long. Optimus came round and found himself unable to move. Megatron made his way over to him. “I have placed a partial sensor block on you; it is merely enough to paralyse you. It’s only temporary.”

“Why are you doing this?”
“I told you.”

Optimus stared at him, his optics filled with confusion, with betrayal and fear at what Megatron had planned for him. Megatron stood over him, his hands behind his back. Optimus felt a wave of dread as Megatron lifted the metal staff he’d seen used on the prisoner. He glared at Megatron. “You wouldn’t dare.” He snapped defiantly. Megatron lunged closer his voice dripping with venom. “Don’t underestimate what I won’t do Optimus.” The staff sparked viciously, Optimus tensed as Megatron waved it over his body. His red optics watching his every movement. Locked onto his face.

Optimus didn’t want to give him the satisfaction of reacting to the pain as Megatron thrust the staff into his chest. Clenching his dentals as hard as he could, he screamed into his closed mouth. Emitting no more than a low rumble. Megatron sneered at his show of strength. He released the staff and without any hesitation placed it above Optimus’s interface port. Optimus felt his capacitor cycle up rapidly, the heat raging through his circuits fading to a dull scar across his sensor net. Megatron pressed the electric staff onto his closed Interface port, Optimus bucked, his back arching painfully, but he did not scream.

Megatron despite being vaguely impressed by the younger ‘bots pain threshold was becoming irritated by his resistance and stubbornness to give in to him. He straddled Optimus again, who was now gasping for release from the staff. Megatron lifted it and Optimus’s body relaxed. ‘This was the first time any ‘bot had sat across him, touched him.’ Megatron mused. If he could help it, he would be the first and the last. His mouth curled as he flicked open Optimus’s interface port, the ‘bot winced. Megatron eyed the green lit interface module with faint surprise, part of Optimus enjoyed this, he was amused. He glanced up at Optimus who had turned his head away and shuttered his optics, shame written all over his face at his own arousal. Megatron sighed, and stroked the module with the staff gently, he did not need to apply pressure, he knew what he was doing.

This time Optimus screamed, the electricity jumped through his module, ripping through his circuits up into his interface port which arced with electric blue current. He jerked so violently Megatron almost lost his balance. This did nothing but amuse the larger ‘bot further. Optimus felt his interface port burning, the sealing collar felt like fire. Megatron let go and he fell limp with a whimper.
“Please Megatron... don’t do this...” His optics pleaded with him, Megatron leaned in pressing his body against Optimus’s, his legs squeezing him tightly. “Beg me.” He grinned.

Optimus could barely think straight he just wanted the pain and the humiliation to stop. “Please stop Megatron.” He whispered. “I beg you... please.” Megatron’s grin widened and he breathed into Optimus’s open mouth. “No.”

Optimus felt another wave of excruciating agony as the staff was plunged into his interface port. Rammed so deeply the wiring within it sparked viciously and frayed. All he could hear was the sound of his own voice roaring with pain. Megatron had clamped one of his hands over his mouth. No one else was to hear him scream, his cries muffled in his grip, he almost broke into sobs as Megatron kept the staff pressed into him. He felt his interface port failing, alarms shooting all over his sensor net. He wished to black out, prayed for it. “You belong to me.” He heard Megatron’s strangely calm voice crawling into his head. “Say it.” He demanded firmly. Optimus couldn’t speak his vocal processor too raw. Megatron slapped him hard and let up on the staff just slightly. “Say it!” He yelled. Optimus relented he had no other choice. “I belong... to you...” He whimpered as the staff circled his sealing collar around the interface port, singeing it. Then he felt nothing.

His whole body ached, he still couldn’t move. How long was it since he’d passed out? Memories of agony washed over him violently. He felt sick. Megatron was still there waiting, he could feel him. What more could he do?

“Ah, I’m glad you didn’t keep me waiting long.” Came the thick, velvet voice. He felt Megatron’s weight press against him. He moaned with resistance, his body aching as Megatron ran his long talons down his frame. He felt the pressure along his interface module, his fingers caressing its length. His data stream pulsed involuntarily. No he didn’t want this.

“Open your optics.” Megatron ordered menacingly. Optimus did as he was told, not wanting to experience the pain of that staff. “Good.” Megatron purred. “You’re learning.”

Optimus glared at him with pure hatred, hatred like he’d never felt. He watched as Megatron opened his own interface port and take out his module, it was fully lit green. Megatron moaned as he flicked the tip. Leaning over Optimus he pressed one arm into his shoulder. “I know this is new for you Optimus, I will make it memorable.” His optics burned into him as he plunged his module deep into his interface port. Optimus yelled with shock. Burnt from electricity he felt his sealing collar tear, his optics almost went black, energon back wash lodged in his throat as he choked on his own screams. This pain was worse, and it grew with each hard pulse of Megatron’s data stream. Wave after wave of agony pounded into him, Megatron lost himself, with each pulse, slamming into Optimus’s damaged port. He roared as his overload took him over. His entire body shaking with tension and release as energon filled the port.

Optimus could only sob pathetically as the energon burst through his systems, the cool fluid stinging his already ragged, ripped wiring. He had no more fight in him, his own module pinging him painfully, calling for release as the overload tore through his sensor net. Lurching to one side Optimus off loaded, his nausea finally defeating him. Megatron growled with pleasure. Lying flush to Optimus’s trembling frame he ran his hands down Optimus’s finials, stroking his face. He forced him into a rough kiss. Optimus whimpered as his glossa forced its way into his mouth.

Megatron purred sliding to one side, his talons raking their way across Optimus’s chassis. Optimus remained still. His body, crusted with energon and splatter from his own off load, trembled in shock. “Shhh... It’s over now.” Megatron’s tone was gentle, soothing. Optimus almost sobbed aloud at the sound. “Tell me you’re mine.” He whispered. “Do you belong to me?”

Optimus shuttered his optics, shame, revulsion pulsing through him as his own aching desire started to fade. “Say it Optimus.”

“Yes.”
“Do you trust me and only me?”
“Yes.” Optimus’s voice was a strangled moan in his throat. He hated himself, he hated Megatron.
“You will obey me?”

“Yes.” He whispered faintly. What else could he do? Megatron was revered amongst the council and had a lot of loyal followers. He could never admit this to anyone; he couldn’t do that to the people that looked up to him. Expecting him to be infallible, untouchable, Prime. Besides who would believe him?

Megatron’s voice was seductive as he ran his fingers across Optimus’s module, he winced at the touch. Megatron stroked his face. “Don’t worry Optimus, I will get you repaired. No one will know what is between us.” Optimus felt nausea building again at his words. He heard Megatron growl, his face filled with lust, Optimus stared at him with disbelief. Megatron held his gaze.

“You shall be rewarded for your obedience.” He growled deeply. Optimus moaned as Megatron flicked open his own interface port.

Megatron relished the data stream as he plunged Optimus’s module into his own port. Despite the damage to the module, it was better than he had expected, slow, cool, building. The data stream quickened as Megatron thrust into it, the feeling was intense. Stronger and faster. He felt Optimus arch his back pushing himself into Megatron as he overloaded hard into him. Then his body relaxed. Megatron detached himself, his face satisfied. He took in every inch of Optimus’s abused body, the sight filling him with desire again. He calmed himself. ‘There will be plenty more opportunities for that.’ He thought as he leant down and placed a gentle kiss onto Optimus’s unconscious labia.

“Plenty more.” He growled deeply.
