Description: After Elita’s death and his own expulsion, Optimus is convinced the future holds nothing good for him. Until Ultra Magnus summons Optimus to his office with an offer Optimus quickly learns he can’t refuse.

For Sinpom.

If Optimus had things his way, he would have sulked in the small room he called his own for the next week. He would have wallowed in his own self-pity and self-hatred until the eviction notice finally forced him out, leaving him to flounder in a society that no longer felt he was of worth.

But a summons from Ultra Magnus was something he could not ignore. There was a tiny niggle of hope, buried in the back of his spark, that maybe the Magnus had changed his mind. Maybe there was forgiveness or a chance. Maybe there was hope.

The smarter, more realistic side of himself dreaded the meeting. There were worse punishments yet, and perhaps Ultra Magnus realized that Optimus had gotten off relatively easy. Perhaps they would strip more from him. His citizenship maybe. Would it be exile? Would he be formally charged? Would he find himself in the Stockade next to thieves and murderers and political dissidents?

He was a murderer. Maybe it was where he belonged.

Optimus’ fingers twisted together. He knew his anxiety showed on his face, but he didn’t have the strength to put up a brave front. Whatever further punishment Ultra Magnus decided for him, Optimus would accept it.

He deserved it.

He arrived at the Magnus’ office and was a bit surprised how quickly they ushered him inside. No one would look him in the optic, and he was taken immediately to the Magnus’ private office, and left alone to buzz the door and announce himself.

Steeling himself, Optimus cycled a ventilation and pressed the call button. The door opened, and when he stepped inside, it closed and locked behind him. Optimus worked his intake. That wasn’t ominous at all.

“Optimus, welcome.”

He blinked. That was not the response he’d been expecting.

Ultra Magnus’ office was understandably large, and the furthest wall was nothing but a long run of windows overlooking Iacon spread out below. Ultra Magnus himself stood in front of the bank of windows, his hands clasped behind his back, but he’d half-turned when Optimus entered. There was even a smile on his face.

“Thank you for coming,” Ultra Magnus said, still in that pleasant voice. “Please join me. Are you in need of fuel?”

Optimus blinked again. “I - umm - No, sir. I’m fully fueled.” His stabilizers carried him forward before he could think otherwise, crossing the massive floor and circling around the desk to join Ultra Magnus at the window.

It was a bit dizzying to be this high up, but exhilarating, too. He could see all of Iacon stretched out below him, and it looked even larger from here. Larger and untouchable.

“Thank you for the offer,” Optimus said as he stood at parade rest, unsure of how to proceed. The last time he’d stood before Ultra Magnus, it had been to castigation and a stripping of a rank he’d never managed to embrace.

“Are you certain?” Ultra Magnus’ smile was soft. He half-turned, gesturing with one hand to a nearby table with a tray on it - a decanter of oil, a tray of energon goodies, and a few small cubes of looked to be high grade were laid out on it. “I have plenty to spare.”

Optimus twitched nervously. He licked his lips. Was it ruder to accept or decline? Was he committing some kind of faux pas by refusing?

Ultra Magnus reached behind him and grabbed the plate with the goodies. It looked so small in his hands even as he turned to offer it to Optimus.

“I’ve been told they are quite delicious,” he said.

Optimus lifted a hand and thanked Primus it wasn’t shaking. “I appreciate your generosity, sir,” he said as he picked two goodies from the plate. There were still many left, but hopefully, two was an appropriate amount.

Ultra Magnus set the tray back on the table and turned toward him. “You are most welcome, Optimus.” He smiled softly. “Now, I’m sure you are curious as to why I summoned you here today?”

“Yes, sir.” He braced himself. “I assumed it had something to do with… with my failure.” The tips of his antennae burned. The goodies felt, at once, heavy in his hand.

“The unfortunate accident, yes.” Ultra Magnus nodded solemnly. His gaze slid to the window. “Iacon is beautiful, is it not?”

Optimus blinked. “I… yes, sir.” What an odd segue. “The greatest city in all of Cybertron.”

“That it is.” Ultra Magnus chuckled softly, and his gaze slid back to Optimus. “Please feel free to indulge, Optimus, while I explain why I called you here.”

“Yes, sir.” He shoved one of the goodies into his mouth, and barely resisted from moaning as the sweet, syrupy energon exploded over his glossa. He’d never tasted anything so refined before.

“Good.” Ultra Magnus inclined his head and stepped closer, near enough that Optimus could taste the edges of his field now. “You were an exceptional student, Optimus. You studied hard and trained harder. You would have graduated at the top of your class, if I’m not mistaken.”

Optimus licked his lips clean and jerked his head in a nod. “Yes, sir. That was my intention.”

“You would have succeeded. You have the potential within you, Optimus. Perhaps not to be a hero, but to be a servant to the Autobot cause most certainly.” Ultra Magnus’ smile softened, turned indulgent. “I hate to see such potential go to waste.”

Optimus’ ventilations increased in pace. “What do you mean, sir?” Could it be? Was this the dash of hope he’d been begging the universe for? He nervously squeezed the goodie, and forced himself to eat it, lest he make a mess.

“I mean, Optimus, that I have, through great effort on my part, and no few strings pulled, managed to find you a commission.”

Optimus’ optics rounded. His spark stuttered. He nearly choked on the sweet, jellied energon. “I don’t understand.”

Ultra Magnus rested his hands on Optimus’ shoulder, big and heavy and warm. His thumbs swept inward, resting on Optimus’ clavicular strut.

“I do believe it is possible to offer you a position within our space bridge repair force, and with it, the title of Prime,” Ultra Magnus said as his thumbs stroked over Optimus’ clavicular strut, gentle and oddly intimate. “It will take much pushing on my part, and even as Magnus, I can’t guarantee that I will be successful. But I am willing to put forth the effort for you. That is, if you are willing to put in the hard work necessary.”

“Of course I am!” Optimus blurted out, surging forward, until he remembered where he was and rocked back on his heelstruts. “I mean, I’m sorry, sir. But yes, I promise. I will work very hard. I am grateful for any opportunity you’ll give me.”

He didn’t deserve it, but Primus, he would. He would do whatever it took if it meant they wouldn’t expel him or jail him. All he needed was a chance. He would prove Ultra Magnus’ faith in him. He swore it!

Ultra Magnus leaned closer, the weight of his hands on Optimus’ shoulders somehow heavier. “Are you certain?” he asked. “This is a big responsibility, Optimus. I will be putting an enormous faith in you. I need to know that you will work hard. That you will do what is necessary. That I can trust you.”

Optimus worked his intake. “Yes, sir. I will. I’m just so grateful for the second chance. I promise I won’t let you down.” Whatever it was, he would do it.

Ultra Magnus smiled. “I believe you,” he said, and his thumbs started stroking again, soft sweeps that brushed over Optimus’ intake now. “It is a space bridge repair position, I admit. It is not much, but--”

“Anything, sir,” Optimus insisted, that tiny nugget of hope daring to bloom into something larger. “This is more than I could have hoped for. I will do whatever it takes to prove your trust in me.”

“Excellent.” Ultra Magnus’ field pushed at his, thick with approval and delight. He tilted his helm even as one hand shifted to cup Optimus’ face.

Optimus froze. W-what? What was Ultra Magnus doing?

“I knew there was potential in you. This is a minor setback. One that can be overcome with hard work and dedication,” Ultra Magnus murmured even as his thumb swept over Optimus’ cheek. “You are loyal, aren’t you, Optimus? To this city, to the Autobots, to me?”

He swallowed thickly. “Yes, sir. I am.” His ventilations stuttered. Ultra Magnus’ field pushed at his again, only now it was warm and sticky.

“Good.” Ultra Magnus’ engine purred. “You are quite stunning, Optimus. Has anyone ever told you that?”

Some of the color drained out of Optimus’ face. “No, sir. I’m, um, I’m quite average.” A tremble whipped down his spinal strut.

“You are far from average, Optimus,” Ultra Magnus murmured, and his thumb swept downward, brushing over Optimus’ lips.

Optimus could not have gone more still if he tried. “Sir, I don’t--”

“I am putting myself on the line for you, Optimus,” Ultra Magnus said in a smooth, even tone. “I am Magnus, this is true, but even I have limits. Everything you do from now on will reflect back on me. Do you understand the risk that I am taking?”

A shiver crawled under Optimus’ armor. His hands formed fists at his sides. “I do, sir. But--”

“Then you understand why I must know I can trust you,” Ultra Magnus interrupted, still in that even tone, though the press of his field was more apparent now. Heavy like thick oil, and so very hot. It prickled against Optimus’ own. “I must know that my faith in you is not misplaced, and that you will be obedient to the Autobot cause, such as you weren’t when you made the poor choice to go Archa Seven.”

Oh.

Optimus cycled a deep ventilation. “Yes, sir. I understand. What would you have me do?”

Ultra Magnus smiled, and for a moment, it almost felt genuine, were it not for an undefinable something that lurked behind his optics. “There is some paperwork that I need for you to sign,” he said as his thumb moved over Optimus’ bottom lip, stroking it again and again. “Along with your personal reassurance that my faith in you is not mistakenly put.”

Optimus’ knees wobbled. He remained standing only because he knew if he ran out the door right now, that was it. This was his last chance.

“Yes, sir.”

“Good.” Ultra Magnus’ hand slid away from his face. The one on Optimus’ shoulder slid to his upper back and further down, until it rested at the base of his backstrut. “The paperwork is on my desk.”

He guided Optimus by the hand on Optimus’ back, urging him toward the desk. “You should look it over, ask me any questions you might have. I want to be sure that you understand the responsibility I am giving you.”

Optimus forced his stabilizers to move. He was very aware of the hand on his back, inches from his aft. The weight of Ultra Magnus’ field against his, the way it pushed and tugged, as if taking over. The heat of him and the fact that Ultra Magnus’ fans were audibly whirring.

There was a datapad on the desk. It was the only thing on the desk as a matter of fact. The rest of the desk was scrupulously clean. A small stylus cup rested in the corner. Ultra Magnus’ in and out box were completely empty. The keyboard for his personal console was tucked to the side. His monitor was powered down.

As if he’d been waiting for Optimus.

Optimus braced himself and reached for the datapad, which was already powered on and open to a document. He expected a lot of legal jargon, but it was actually rather simple.

He picked it up and started to read - or skim, rather. He couldn’t really focus. The hand on his backstrut started to move, short little sweeps down, each stroke coming closer and closer to his aft. Ultra Magnus crowded against his side, so very present and overbearing.

“I, um, don’t know much about repairing space bridges,” Optimus admitted, his vents stuttering as Ultra Magnus moved until he stood behind Optimus, leaning over him. He felt the warmth of Ultra Magnus’ ex-vents over his antennae, and they burned with a mixture of shame and dread.

“You will have a team,” Ultra Magnus murmured, his hands stroking down Optimus’ sides now, until one of them found Optimus’ aft and cupped it. “You are to be their commander. Ensure they stay on track. Log missions. Et cetera. You will report to me.”

That was highly… irregular.

Optimus wondered if part of his duties would now extend beyond space bridge repair. What if Ultra Magnus intended for Optimus to become some kind of personal… um, soldier? Or something.

He didn’t dare think of the possibilities.

“Oh, I see,” Optimus said, and was ashamed that his vocalizer filled with static a little.

Ultra Magnus hummed his amusement. “Do not worry, Optimus. I’m sure you will work hard to prove that you are worthy of this opportunity.” He ex-vented again on Optimus’ antennae.

Optimus opened his mouth to respond, but it dribbled off into a stuttered noise as Ultra Magnus’ lips enclosed around the tip of his antennae. Denta gave it a soft nip, and a glossa flicked over it.

Optimus gasped a vent, sagging a little where he stood. Sensations both hot and cold went running through his frame.

Oh, Primus. Was he going to stand here and let Ultra Magnus do this? Whatever this even was? Did Ultra Magnus want him like that? Did he seriously want to frag Optimus? Was that why he’d been called here?

Realization slammed into Optimus. His spark squeezed.

Was this how he was supposed to prove his loyalty? With his frame? Was that all he was worth now? Some kind of… frag toy? Or a… a buymech?

How could Ultra Magnus do this? He’s supposed to be a leader! He’s always been Optimus’ hero, and here he was, manipulating him. Backing him into a corner.

Despair crowded at the back of Optimus’ intake. He trembled, hands tightening around the datapad. His armor clutched tight to his protoform, his field a wobbly mess.

Ultra Magnus hummed around his antenna before releasing it with a slow slide of his mouth. “You are so responsive,” he murmured. “Is this your first time?”

Optimus’ optics shuttered. “No, sir,” he said, swallowing over a lump in his intake. He didn’t elaborate. He didn’t want to think about the happier times, or the knot in his spark where the happiness he, Sentinel, and Elita shared had come undone.

“Mm. Pity.” Ultra Magnus’ hand slid down Optimus’ aft again, only now his fingers went further, slipping between Optimus’ thighs, the tips of them brushing the panel concealing his interface array. He rubbed the panel gently. “Open for me, Optimus.”

It was not a request. That was clear in Ultra Magnus’ tone.

Optimus gnawed on his bottom lip. His shoulders hunched. What would happen if he refused? Would the datapad be taken from him? The opportunity as well? Would he find himself facing all of those dreaded repercussions he feared when he first received the summons?

Ultra Magnus’ field pushed at his harder, as if swallowing him whole.

Optimus’ helm dipped. He obeyed, a shudder racing down his backstrut, as his panel snicked aside, baring his valve and spike to the air. He wasn’t aroused in the slightest, and both of them reflected that.

“Very nice,” Ultra Magnus said as two of his fingers traced over and around Optimus’ rim, exploring it gently. His other arm circled around Optimus’ frame, his hand flat on Optimus’ chest. “If I am to fit inside this pretty valve of yours, I must prepare you properly.”

Optimus’ ex-vents surged out of him in a shuddery mess. The datapad crackled in his grip.

One finger found his anterior node cluster and gave it a gentle rub. Optimus’ knees wobbled. The most distant stirrings of pleasure woke in his array, and he wasn’t sure if it was actual arousal or anxiety that made his valve twitch.

“Have you taken anyone of my size before, Optimus?” Ultra Magnus asked as he circled Optimus’ node again and again, his lips nuzzling each of Optimus’ antennae in turn.

Optimus curved forward, away from Ultra Magnus’ touch, but there was nowhere to go. He was trapped between the desk and his leader, Ultra Magnus’ presence all consuming.

“No, sir,” he said, truthfully. He didn’t dare admit that he’d taken Sentinel and Elita both at once. He didn’t want Ultra Magnus to get any ideas.

Well, anymore than he already had.

“I see.” Ultra Magnus sounded pleased. He pressed harder against Optimus’ back, his finger dipping into Optimus’ valve as a thin stream of lubricant finally dampened the sensitive protomesh walls. “Well, I have taken someone as small as you before. I will fit with a little work.” He leaned closer and nuzzled the back of Optimus’ helm.

His finger dipped deeper into Optimus’ valve, curling to rub along the ring of sensor nodes just behind his rim. Optimus sucked in a ventilation, his frame twitching, as a tiny jolt of pleasure lanced through his array. Those nodes were particularly sensitive and never failed to excite him.

“Mmm. Very responsive,” Ultra Magnus murmured. His mouth wandered lower, tucking into the curve of Optimus’ intake. His lips brushed over Optimus’ cables, a parody of lover’s intimacy. “Have you finished reading the datapad yet?”

Finished? Optimus couldn’t remember the last time he’d looked at it. He’d been too focused on Ultra Magnus touching him, on tracking the motion of every finger, every ex-vent, braced for every new invasion.

He swallowed thickly as the wet noise of Ultra Magnus slowly fragging him with one finger became louder when Ultra Magnus added a second. Together, they were the width of a regular spike, and Optimus’ calipers clutched at them. Greedily, if you asked him. His frame didn’t seem to care that his spark wasn’t in it. Little bursts of pleasure kept peppering in his array, his nodes sparking to life.

“No, sir,” Optimus admitted, the datapad screen wavering in front of his optics. “I’m sorry.”

“That is quite all right.” Ultra Magnus kissed his intake cables, his vocalizations causing little puffs of warm ex-vents to tease Optimus’ neck. “I’m sure I am distracting you. Set it down, Optimus. There will be time to read it thoroughly later.”

Later.

Optimus slowly lowered the datapad. “Yes, sir.” He rested his hands on the desk to either side of it, braced against the overpowering weight of Ultra Magnus’ frame and field over him.

His aft rubbed against Ultra Magnus’ upper thighs. Two fingers worked in and out of his valve, twisting and stroking, until lubricant trickled free and slicked Optimus’ thighs. His shoulders hunched, his antennae and neck treated to a soft assault of lips and glossa.

“Please, Optimus. We are in private. You may call me Ultra,” his leader murmured, glossa flicking over the tip of Optimus’ antennae.

He eased a third finger into Optimus’ valve, and Optimus hissed quietly. It was a stretch now, forcing the width of his calipers wider. Not bad, not painful, but definitely more tangible. Not that his valve seemed to care. It greedily cycled more and more lubricant and spat charge from his nodes.

Optimus shaped the name of his Magnus with his mouth, but couldn’t bring himself to say it. “Yes, sir. I will… try.”

“That is all I ask.” Ultra Magnus’ lips descended to his audial, ex-venting warm and wet over it. He pressed hard against Optimus’ back, trapping his hand between himself and Optimus’ aft, his fingers still working deep and firm within Optimus’ valve.

“You grip me so tightly. I cannot wait to feel you on my spike,” Ultra Magnus murmured, even as his free hand slid up Optimus’ chestplate, fingers brushing over his intake before they found his lips. He traced them slowly, intently. “However, there is something you could do for me first, if you are so inclined.”

If. He spoke it as though Optimus had the choice.

Somehow, he suspected he did not.

“Of course, sir,” he said, though his internals tightened into uneasy knots, and the goodies he’d consumed sat in his tank like hunks of unprocessed ore.

“Excellent.” Ultra Magnus gave one last stroke to his valve before he withdrew his fingers and leaned back.

The heat of him retreated, and Optimus shivered as cold washed in. He didn’t know if he was overheating because Ultra Magnus was so warm, or because the stress was making his temperature spike. His own engine was producing this pathetic whining noise and he couldn’t seem to make it stop.

Optimus slowly turned, hoping his shame didn’t show on his face. Hoping Ultra Magnus didn’t want him to look eager for it. He couldn’t bring himself to fake it.

No sooner had he turned than Ultra Magnus cupped his face - with the hand still sticky with Optimus’ lubricant - and leaned down, brushing his mouth over Optimus’. The kiss was almost chaste, just a brush of lips together, before Ultra Magnus returned, pressing his mouth firmly to Optimus’. He made a humming noise of delight as Optimus felt the wet poke of a glossa against the seam of his lips.

He shuttered his optics and relented, parting his lips to allow the glossa within. Ultra Magnus purred with pleasure and deepened the kiss, his glossa laying claim to Optimus’ mouth, his grip on Optimus’ helm falsely romantic. Optimus barely responded, passive as he let Ultra Magnus explore his mouth and kiss him as though they were lovers.

His hands clenched at his sides, so tightly into fists that his knuckle joints ached. He was shaking, he knew he was. He could hear his armor clattering, and he couldn’t seem to make it stop.

“Mmm.” Ultra Magnus ended the kiss, but not without nuzzling Optimus’ face with his own. “I can taste the candies on your glossa. Did you enjoy them?”

Optimus cycled a ventilation. “Yes, sir.”

Ultra Magnus’ lips curved, almost indulgent. “You may call me ‘Ultra,’” he reminded Optimus as though he’d forgotten. His thumb swept over Optimus’ bottom lip, over the wetness his glossa left behind. “You have a beautiful mouth. I should like to see it wrapped around my spike.”

The shudder worked its way from Optimus’ pedes up to the crown of his helm. He couldn’t bring himself to speak so he simply nodded and started to lower himself and his gaze. He focused on Ultra Magnus’ frame, his optics skirting over the prominent Autobot symbol on his leader’s chesplate.

It felt like the badge were mocking him.

Optimus lowered himself to his knees, Ultra Magnus’ hand slipping to rest on the top of his helm instead of cupping his face. He lifted shaking fingers, resting them on Ultra Magnus’ hips, and braced himself.

“Only a taste,” Ultra Magnus murmured as he urged Optimus toward his panel, which was slowly spiraling open. “I am so pleased with your performance so far. I truly believe that my faith in you is not being misplaced.”

The reminder, Optimus knew, was not accidental. Ultra Magnus wanted him to remember exactly what his frame was paying for. How cruel of him.

Optimus’ face burned with humiliation. He wanted to duck his helm, hide from Ultra Magnus’ approving gaze, but he couldn’t. Not with Ultra Magnus’ spike emerging, pressurizing quickly, pre-fluid already beading at the tip. He was massive, proportioned to his size, his spike a bright blue unit ribbed with bands of white. Optimus’ jaw ached just looking at it.

Ultra Magnus’ hand on his helm was a steady, forward pressure. It pushed him closer and closer to the Magnus’ spike, until the tip of it bobbed millimeters from his lips. Optimus’ tank churned, but he obediently parted his lips and allowed Ultra Magnus to slip into his mouth. He tasted pre-fluid immediately, and Ultra Magnus throbbed on his glossa, so hot and firm already. How long had he been aroused? Had he been fantasizing from the moment he sent the summons for Optimus? Had this been his plan all along?

Probably so, given the way Ultra Magnus’ fans whirred and his vents thrummed and his frame radiated heat like a furnace. Every inch of him was control, though the pressure of his fingers grew firmer.

“Ah, but you are beautiful,” Ultra Magnus praised from above as he urged Optimus deeper onto his spike, the thick length rubbing firmly against Optimus’ glossa. “This is a talent I did not know you had, Optimus. You should include it on your resume.” He chuckled as though it were a joke.

Optimus tried not to purge. His fingers shook where they gripped Ultra Magnus’ hips. He just wanted this to be over.

He forced himself into action. He shifted his weight on his knees and swallowed as much of Ultra Magnus as he felt he could fit. He lashed his glossa around it, oral lubricant welling up in his mouth and dribbling out the corners. He had to divert his oral ventilations. His jaw did indeed ache.

Ultra Magnus gave a soft sigh of satisfaction. His hips rolled forward, ever gently, pushing himself deeper into Optimus’ mouth. His field buzzed against Optimus’, plucking at the edges and demanding more. The tip of his spike bumped against the back of Optimus’ intake and lingered there, grinding against the soft protomesh.

His fingers shook around Optimus’ helm before he abruptly drew back, the tip of his spike painting over Optimus’ lips.

“Ah, forgive me,” he said, his voice regretful. “Any more and this would have ended too soon for us. You are quite skilled, Optimus. You should be proud of yourself.”

Hot and cold warred for control within him. “Thank you, sir,” he rasped.

Ultra Magnus smiled at him and cupped his jaw. He urged Optimus to stand with a bit of pressure on the bottom of his jaw. “I seem to recall giving you permission to call me by name,” he said. “But now there is something in the way you say ‘sir’ that I’m growing fond of. Continue, if you like.”

Optimus blanched. Now this, too, would be tainted.

He swallowed, still tasting Ultra Magnus on his lips and glossa. “Yes, sir,” he said, going cold all over, like ice dripping into his lines. His knees wobbled again as he remembered the size of Ultra Magnus’ spike.

Ultra Magnus hummed an approving noise and leaned down to kiss Optimus once more. It was less claim this time as it was a brush of their lips together, Ultra Magnus nuzzling against him.

“There is a part of me that wishes to keep you,” he said, before he rested a hand on Optimus’ hip and gave it a squeeze. “Now, it is unfair of me to demand all the pleasure for myself.” The hand shifted, moving inward, fingers dipping between Optimus’ legs to play with his valve again. “I should like to taste this again. Would you like that, Optimus?”

Oh, Primus.

Optimus’ vents stuttered. Heat built at the back of his optics, the shame making his intake close tightly. If he spoke the truth, would Ultra Magnus throw him out? Would it be a rejection of this, his final chance?

Did he even deserve to reject Ultra Magnus’ generous offer? This was what he deserved, wasn’t it? For failing to save Elita. For failing to protect Sentinel. For failing.

Optimus bowed his helm, and felt a shudder race through his frame. “I am a loyal Autobot,” he said instead.

“That is all I wanted to hear.” Ultra Magnus’ finger rubbed firm circles on his anterior node, making his hips jerk and his array pulse with heat.

Ultra Magnus pulled away and placed his hands on Optimus’ shoulders. They slid down to cup Optimus’ aft and lifted him with ease, placing him on the desk.

“This, I think, will be easier,” he said as he urged Optimus to lie back, even as he nudged himself between Optimus’ knees, his spike rubbing over Optimus’ inner thighs. “That and you look enticing on my desk.”

Optimus’ hands bunched at his sides. “Thank you,” he said, unsure of what else he could say honestly. All of the tension returned, his armor clamped so tight he wasn’t ex-venting heat properly, and the tremble came back, making him ache from clenched cables.

Ultra Magnus’ hands swept from his hips to his knees, urging them to press in around his hips. He pulled Optimus’ aft to the very edge of the desk and rolled forward, the head of his spike nudging over Optimus’ rim. It painted itself in Optimus’ lubricant, and rubbed teasingly against his anterior node cluster.

Optimus’ face filled with heat. He shuddered, a mix of shame and arousal. He wanted to cover his face, but he suspected that seeing his expression was part of what Ultra Magnus wanted. Because Ultra Magnus was staring at him, optics devouring Optimus’ face.

“Do you ever self-service, Optimus?” Ultra Magnus asked. One of his hands palmed Optimus’ array, the heel of it scrubbing over his spike sheath, where only the head of his recessed spike dared poke into view.

“I-I do,” Optimus admitted even as his antennae spit sparks out of sheer embarrassment. He had a feeling he knew where this was going.

Ultra Magnus hummed thoughtfully. He kept rolling his hips forward, spike rubbing over Optimus’ thighs, his rim, his node, everywhere but actually sliding inside of him. “And do you prefer your spike or your valve?”

“N-no preference,” he admitted. Because after this, he wasn’t sure he’d ever want his valve again.

“Hmm.” Ultra Magnus rubbed over the head of his spike and little by little, Optimus’ array responded, until his spike reluctantly pressurized into Ultra Magnus’ warm grip.

He gave it a squeezing stroke as his free hand held Optimus’ hip, keeping him in place for a shallow grind of his spike against the rim of Optimus’ valve. “Would you show me? I want to make sure I learn how best to touch you.”

Oh, Primus. Oh, no.

He’d been right.

“Y-yes, sir.” Static crackled in his vocals. Heat gathered behind his optics, but he rallied enough to swallow it down.

He forced his right hand to unclench. He forced himself to reach down the length of his frame, to wrap his own fingers around his spike the moment Ultra Magnus released him. He forced himself to remember nights spent hunched over, stroking himself as he tried to keep his cries quiet, while thinking of Sentinel and Elita and whoever else decided to haunt his fantasies.

“Beautiful,” Ultra Magnus murmured as he held Optimus’ hips and ground against his valve, the head of his spike catching on Optimus’ rim and rubbing over it repeatedly. “I want to see your pleasure, Optimus. I want to see you overload. Will you do that for me?”

He gnawed on his bottom lip. “Yes, sir,” Optimus forced out as he squeezed his spike and started to stroke, his hands shaking where he held himself.

Nausea and shame coiled and twisted together in his tanks, but it wasn’t enough to stop his frame from responding. From pleasure throbbing into his array, blooming through his groin in a slow spread of warmth. His valve cycled hungrily, lubricant soaking his aft and dripping onto the desk. His spike pulsed, the smallest drip of pre-fluid squeezing from the tip.

“Excellent,” Ultra Magnus purred before he tilted Optimus’ hips and finally sank into Optimus’ valve in one slow, steady push. His spike parted the squeeze of Optimus’ calipers with ease, grinding against Optimus’ valve walls and exciting every node along the way.

Optimus whimpered, his backstrut arching, thighs trembling where they pressed against Ultra Magnus’ hips. It felt good, despite it all. He couldn’t remember the last time he’d been filled so deeply, or the last time someone had nudged his ceiling node with such ease.

His optics flickered. He panted several droughts of desperate air through his vents. He squeezed his spike as it throbbed, his free hand clawing at the desk. He knocked over something in his blind pawing - the datapad he thought - and ended up gripping Ultra Magnus’ hand by the wrist. He held tight, squeezing, though it did little to affect Ultra Magnus’ reinforced battle armor.

“Ahh.” Ultra Magnus sighed a moan, his energy field rippling with bliss and satisfaction. His spike throbbed a happy beat. “I knew you would feel good.”

Ugh.

Optimus gritted his denta. He expected Ultra Magnus to frag him roughly to pound him into the desk. Instead, the Magnus pulled back and started thrusting into him slow and deep, each drag of his spike in and out of Optimus’ valve only serving to stir the pleasure higher and higher within him. His hands cradled Optimus’ hips, pulling him into each thrust, his thumbs stroking over Optimus’ armor as if in comfort.

Ultra Magnus’ face was one of delight and concentration. His field rippled and flexed against Optimus’, hot and hungry, sucking him into the maw of it. His engine rumbled, the pitch of a mech surrendering to arousal.

And then he leaned forward, over Optimus, nuzzling against his face as though they were lovers and this was just a naughty little tryst for fun’s sake. His lips traveled over the curve of Optimus’ jaw before they found Optimus’ mouth. He kissed Optimus, as slow and deep as every thrust into Optimus’ valve, until his spike worked deep and ground hard against Optimus’ ceiling node.

He gasped, twitching beneath Ultra Magnus, unconsciously stroking himself faster. Shivers and charge both danced up his backstrut. He squeezed his spike, jerking himself with every trick he knew, anything to make himself overload faster and get this over with. His valve clenched around Ultra Magnus’ spike, cinching tight, greedily slurping up the charge Ultra Magnus’ spike fed him.

Optimus’ squeezed his optical shutters closed and tightened his grip on Ultra Magnus’ wrist. He bucked up against Ultra Magnus, driving his spike deeper, and pushed into his own hand. He squeezed his spike, stroking himself faster and faster, as the arousal in his array coiled tighter and tighter.

He hated it. He hated it so fragging much, but his frame didn’t seem to care. Instead, his engine revved loud enough to be audible, his field flared, and lubricant seeped out from around Ultra Magnus’ spike. He squeezed down as though trying to keep Ultra Magnus within him, and fingered his spike head, and whined into the kiss Ultra Magnus insisted upon, glossa plunging over and over into Optimus’ mouth, to the same tune as his spike in Optimus’ valve.

Overload, when it finally took him, was a relief. Optimus whimpered as a weak stream of transfluid spurted from his spike, and his valve fluttered madly around Ultra Magnus’ spike, charge leaping from his nodes to latch. He writhed beneath Ultra Magnus, gasping for cold air, tearing his lips away from Ultra Magnus’ mouth to pant into his own shoulder.

This left his intake and neck ripe for the taking, and Ultra Magnus took advantage of it. He purred hungrily, denta and glossa licking and sucking at Optimus’ cables as he pushed harder and faster into Optimus’ valve, taking him with more vigor than Optimus would have expected of the old mech.

He grabbed onto Ultra Magnus to keep from getting squished beneath the older mech’s bulk and tried to swallow down the cries as Ultra Magnus fragged him deep every time. As he pressed harder, forcing Optimus’ thighs to the limit of their flexibility, and ground against his sore ceiling node fiercely. The desk rattled and squealed beneath them.

Optimus hoped no one could hear them. He hoped the sound didn’t carry. He prayed there wasn’t a camera here to witness his shame.

And he prayed that Ultra Magnus would be finished soon.

It was the only prayer Primus granted.

Ultra Magnus ex-vented into his intake, his grip on Optimus’ tightening. His rhythm stuttered as he thrust fiercely into Optimus, bottomed out, and finally, Optimus felt the hot splash of transfluid deep within him. Ultra Magnus moaned into his audial, murmuring something nonsense that Optimus couldn’t hear through the static.

Ultra Magnus’ hips made little jerks as his spike spurted, the rest of his frame absolutely still. His field swallowed Optimus whole and spat him back out, back into his frame, as the last of overload retreated from Ultra Magnus. His vents whirred noisily, his cooling fans even more so, as Ultra Magnus braced his arms on the desk and pushed himself upright.

His hips were still pressed to Optimus’, his spike buried deep. Optimus dared unshutter his optics. Ultra Magnus was looking at their frames, where they were still joined, and Optimus didn’t know what to call the expression on his face. Hunger. Possession. Lust. A mix of all three.

“That was wonderful,” Ultra Magnus said as he stroked his hands down Optimus’ sides. “You did so well, Optimus. I am proud of you.”

Optimus peeled his fingers away from his spike, which was rapidly depressurizing back into the safety of its sheath. “T-thank you, sir.”

“Mm. I do love it when you call me ‘sir’,” Ultra Magnus murmured, and his glossa swept over his lips. He leaned back, his spike easing from Optimus’ valve, achingly slow. “If I did not have another meeting this afternoon, you are enough of a temptation that I would enjoy you again.”

His hands stroked over Optimus’ sides again, his field pulsing warmly against Optimus’. “I knew my trust in you would not be displaced,” he added as his spike finally slipped free.

Optimus cringed as his valve contracted. He could feel the fluids dribbling downward, seeping out of him. As much as he wanted to snap his thighs back shut, he couldn’t. Not with Ultra Magnus still firmly emplaced between his knees, and especially not with Ultra Magnus now reaching for his valve, his fingers stroking around Optimus’ swollen, soaked rim.

“Beautiful,” he murmured, before he tapped Optimus’ array with one finger. “Close your panel, Optimus. You wouldn’t want to make a mess.” He chuckled softly. “That would be interesting to explain to the cleaning staff.”

A protest rose and died on Optimus’ glossa. He shuddered as he obeyed, trapping Ultra Magnus’ release within him. He wondered, when he stood, if it would slosh against his valve panel. If it would seep past and stain his thighs.

He wondered if that was Ultra Magnus’ intent all along.

“I did not hurt you, did I?” Ultra Magnus helped Optimus off the desk. His stabilizers wobbled beneath him, but his knees held, for all that his joints felt like jelly.

He shook his helm. “No, sir.”

“Good.” Ultra Magnus dug around in subspace and offered Optimus a mesh cloth. “Here. You seem to have made a bit of a mess.” He gestured to the few spatters of transfluid on Optimus’ abdomen and hips.

His face burned with humiliation. Optimus ducked his helm. “Thank you, sir.”

He wiped at himself in vain, even as Ultra Magnus reached around him, scooping the datapad off the table. He tapped his fingers over the screen, and the datapad chirped cheerfully back at him.

Optimus did not know what he was doing. He couldn’t see either, so he focused instead of making himself presentable. Or as presentable as he could given the paint scrapes on his thighs and on the transsteel of his chestplate.

“I have added my designation glyph to your file, Optimus,” Ultra Magnus said as Optimus tucked the dirtied mesh cloth into his subspace. He assumed Ultra Magnus would not want it returned. “All it needs now is your signature.” He offered the datapad over.

Optimus took it once again, alarmed to find his fingers were trembling. “Thank you, sir.” Static etched his words, and his thoughts felt stretched and distorted. All he could manage was obedience.

“This is yours to keep, Optimus. Feel free to read it in depth,” Ultra Magnus said as he gestured for Optimus to move back around to the front of the desk. “Once you have signed your agreement, you will be contacted for your new assignment. Your new title is already yours.”

Optimus’ hands tightened on the datapad. “I understand, sir.” He looked down at the screen, at the glyph denoting Ultra Magnus stamped in the upper right hand corner of the terms and conditions now. It hadn’t been there before.

He dreaded to see what the terms were. He doubted the words ‘frag toy’ had been used, but there were ways around that, weren’t there? After all, Ultra Magnus had never once said to him, ‘you must frag me to get this opportunity’. It was all implicit. Manipulation.

Deceptive.

“I knew you would. You have always been a very good student.” Ultra Magnus offered Optimus his hand. “Congratulations, Optimus Prime. I know that you will do myself and the Autobots proud.”

Optimus startled at hearing the title attached to his own name. It suddenly felt a lot less like the honor he thought it would. It was tainted now, stained with the same transfluid that spattered his hips and thighs, despite his attempts to wipe it away.

He offered his hand and shook Ultra Magnus’, his field crackling against his leader’s. A mech he had once admired, possibly to a fault.

No. Not possibly. Definitely.

“Thank you, sir,” he said, and was grateful his voice didn’t crackle, despite the tautness in his frame, the heat in his optics, and the urge to hide in a dark corner.

“You are most welcome.” Ultra Magnus squeezed his hand before releasing him. He sat in his chair behind his desk as though it were business as usual. “Memorize my comm, Optimus Prime. I’m certain I will call you back to Cybertron from time to time, for private missions, you see.”

Private missions.

Was that code for more fragging sessions?

Optimus could barely contain his shudders. He felt like he’d made a deal with Unicron. He felt like he was being used and discarded, and he longer had anyone to pull him out of the dark. He’d left Elita to die, and Sentinel would hate him forever for it.

He didn’t deserve to be pulled from the mire.

He dipped his helm in a bow. “Yes, sir. I will stand at the ready.”

“Good.” Ultra Magnus smiled, bright and approving. “You are dismissed, Optimus Prime. Perform well. I know you will be a testament to my name.”

Optimus snapped off a salute, if only to hide the nausea crawling up his intake. “Thank you, sir. I will.”

He spun on a heelstrut, hoping Ultra Magnus missed the disgust in his face. He honestly wasn’t even sure if it was directed at Ultra Magnus or himself anymore. He’d bought and paid for his position with his frame. He didn’t know what to think of himself now.

All he knew was that he needed a shower. A scalding one.

And soon.
