Chapter Text
Cybertron has a new Magnus, and all of Iacon city packed it's stadium to witness the coronation of Sentinel Prime and the triumph of the Autobots. The Decepticons have been defeated by Optimus Prime and his motley crew, with the formerly disgraced prime delivering the potential tyrant back to Cybertron in cuffs. The celebrations lasted cycles, though Optimus' triumph was quickly overshadowed by the announcement of Ultra Magnus' retirement. Optimus sat in the stadium, his antenna flicking in annoyance as he watched from the olfactory-bleeders, knowing in his spark that he should be down on that stage with Sentinel and Ultra Magnus. "Least I wouldn't be blinded by Sentinel up here." He grumbled. Sentinel had on a garish gold cape and his armor was shined to perfection, a slag eating grin on his face as he soaked in the cheers and wild howls of the audience. Ultra Magnus stood beside him in a simple dark blue and black cape, almost leaning on his Magnus hammer.
The old bot recovered almost completely from Shockwave's assassination attempt, but it seems the autobot leader was more pained by Sentinel's peacocking. Though he was professionally neutral, his doubt and annoyance was clear as Sentinel almost pranced around the stage like a protoform at a dance recital, absorbing all the praise he did not earn. Ultra Magnus tapped his hammer tip on the stage, finally stopping Sentinel as he grinned and stood proudly beside Ultra Magnus. The cheering stopped as all optics were directed at Magnus, who stared down at Sentinel with intense, spark-searching eyes. "By the power invested in me, I declare you, Sentinel Prime, as our new Magnus. As you accept this hammer, please remember to use it as both weapon and tool." Sentinel nodded, kneeling down to accept the powerful hammer. Ultra Magnus carefully laid it within Sentinel's servoes, a smile hovering on his faceplate. One of relief. "Now rise. Sentinel Magnus." Any other words were drowned out by the uproar in the crowd, most in favor of this new Magnus as Sentinel raise his hammer in the sky, a crazed twinkle in his eye. "A golden age is upon us! Under my rule, we shall outshine all the stars in the universe as we once did!" The crowd went hysterical, no one noticing the wink that Sentinel gave Ultra. No one besides Optimus.
There was a massive, loud state-sanctioned party in the streets as the cycle passed by. Optimus tried to intergrate into the crowd, but he often found himself pushed out and leaning against the wall of an alleyway. Some cheap energex swirled in his can as he stared at the back of Sentinel's head, trying to pick out his words to see any official policy he will enforce. Instead all he heard were drunken rambles about "sparklings" and "carriers". He sighed and took a gulp of his drink, tugging on his cap as he tried to block out the noise. As he contemplated going back to his apartment, a sweet, smokey smell filled his olfatory sensor. Curiosity overwhelmed him, and he abandoned the party readily to find the source.
It led him to the top of a building, the scent almost intoxicating. Optimus poked his head from the stairwell, finally finding the source. It was a cigarette being smoked by the former Magnus, it hanging loosely from his fingertips as he puffed out smoke into the night air. Optimus was used to seeing his mentor smoke, but the thing that gave him pause was his outfit. It was a shimmering blue-and-black dress, around thigh length. There were no straps, it only being supported by his thighs and massive chest. There were cutouts on his belly, hips, and chest that were almost torn from his pudgy mesh and extra armor plating. It seems that he has gained a few tons through megacycles, either through age or inaction. Optimus' optics kept being drifting to his crotch, however. His dress had a slit in the crotch that allowed easy access to a potential mate, though it was covered with a distressingly small skirt that constantly rode up his thighs. Primus, why did he squeeze himself into the tightest dress in the galaxy? His antenna lowered as he ducked down, trying to compose himself. He may not be a Magnus anymore, but surely he was too old to wear something so provocative? Optimus stifled a groan and held his head in his servoes, hating how his spike threatened to pop out. But how he carnally desired those wonderful cutouts, and how he wanted Ultra Magnus terribly right now.
He didn't even notice when his engine clicked on in his arousal
He almost didn't notice when Ultra stared down at him.
Optimus faintly heard Ultra Magnus' words from above him, and embarrassment washed over him as he tried to meet the former Magnus' eyes, though he blushed at Ultra Magnus resting his considerable chest on the guardrail. Ultra Magnus frowned a little and straightened, somehow maintaining a sense of regality despite his clothing choice and lack of title. "Optimus Prime? Were you looking for me?" Optimus could only bob his head, terrified to speak in case he accidentally reveal how much he wanted to frag him over that guard rail. Ultra Magnus huffed and stood by the balcony, beckoning his pupil over with a flick of his antenna. Optimus did not even feel himself walk over, he so desperately wanted to drink in Ultra Magnus' presence.
Ultra Magnus relit his cigarette with a sigh, taking a large breath that made his dress audibly creak. Optimus' servoes nearly crumbles the banister at the sight, him stiffening as he tried to pay attention to his mentor's words. "You should be down there, you know. With all of those other young bots." Optimus shook his head, daring to inch closer to Ultra Magnus' side. "Nah, it's too overwhelming for me. You know I was never much of a party bot." Ultra Magnus smiled a little, his servo hovering near Optimus' side. "Ah, indeed. You always have been so well behaved." Optimus blushed harder and tried to turn away, though judging by Ultra Magnus' laugh it seemed that he saw. "I just tried my best, sir." He bit his tongue as he felt Ultra Magnus' belly squish against his side, his chin gently lifted to stare into his optics. Optimus tried to cup his hips, though his servoes merely hovered over Ultra Magnus' curvy form. Ultra smirked and grabbed Optimus' servo, pressing it into his hip as he winked down at Optimus. "No need to call me "sir" anymore, Optimus Prime. You outrank me now. And ah, feel free to put your servoes on me as you please. I fully consent to this." Optimus stammered before immediately shoving his face into Ultra Magnus' chest, breathing in his sweet, smokey scent.
Air rushed through his vents when Optimus finally popped his head out of Ultra Magnus' bountiful chest, blushing up a storm as the older bot gently stroked his head, yearning clear on his faceplate. Optimus cradled his hips, admiring the dress' craftsmanship despite it's current abuse. "I never would have taken you for a dress bot, Ultra Magnus." He hummed, Ultra Magnus being bemused by the use of his former title. "You may just call me Ultra, Optimus. And well, there is plenty about me that you do not know about. This dress is a relic of my past, which is clinging to me as much as I cling to it." He huffed and readjusted it on his belly. Optimus stared as the mesh bounced slightly, something breaking inside of him.
"You still are such a teaser, Ultra. Punish him for it."
A strange voice echoed in his head, deep, sultry, and foreign. Yet still unmistably him. Optimus licked his lips, a predatory grin on his face as he roughly grabbed Ultra's waist, the old bot's eyes widening in excitement as Optimus shoved him against the wall. Ultra beamed and put his servoes up, panting as he seemed rather excited for Optimus to frag him against the wall. Optimus grabbed his head roughly to pull him down and kiss him, but something in his programming screeched at him to stop. He let go of Ultra, cursing at his insubordination. Ultra took in Optimus' hunched form, the poor bot clearly turned on yet incredibly guilty for it. Ultra smiled and hugged Optimus closer to him, wanting to soothe the young bot until Optimus grabbed his aft, a newfound confidence in him. "There is a motel a few blocks away from here. Meet me there, without the dress. I can...mm." He stared at his thick waist and hips, as if uncertain about his spike size in comparison to the former Magnus. Ultra purred a little, kissing his cap. "I can spike you then, Optimus. Just to help you for your first time." Optimus nodded wordlessly, his mind occupied as he placed both hands on either side of his belly. Measuring him. Ultra seemed bemused, he knew younger bots liked to overexagerrate. He surely is not that large. "I'll see you there. Sir." He winked and walked down the stairwell, Optimus nearly blue screening at his purr. Seems the old bot still got it.
