His self-repair worked fervently. Leaks were patched up so he no longer bled energon everywhere. But his reserves were dry; he was down to thirteen percent.
Thoughts were hazy.
He’d tugged on his chains to no avail. They were strong and he was weak. It had to be more than the energon loss. Megatron must have done something to him. Or more likely, had his pet spy do it. Infected him with some kind of virus. Or sedation program. On top of the stasis cuffs.
He had one consolation. If Megatron was here, then Prime had to be somewhere nearby. If he even cared.
He’d care if it was Sideswipe.
Sunstreaker made a noise of derision.
It didn’t matter. He’d been in a Decepticon spacecraft. The Autobots wouldn’t have known him to be inside it.
There was no rescue.
He was on his own. But how was that any different from the usual? The Autobots seemed content to let him wreak havoc on his own, too.
A sound pierced the silence. Someone was coming. Megatron again?
Sunstreaker lifted his helm, staring as the lights flicked on. Not just emergency lights this time, but the whole cell lighting up. His optics cycled down at the sudden influx of brightness.
“Well, well. If it isn’t my favorite gladiator.”
That was definitely not Megatron.
A red and silver mech cut off the energy bars to the cell and stepped inside. He was smaller than Sunstreaker, and tires indicated a vehicle mode. Sunstreaker didn’t recognize him and couldn’t see a Decepticon symbol anywhere on the mech.
“Who the frag are you?” Sunstreaker demanded, entire frame tensing with unease. He was overly aware of his current vulnerability.
“There’s no need to be afraid, Sunstreaker,” the mech said, coming close enough that Sunstreaker’s olfactory sensor picked up the sweet scent of his expensive wax. “I’m a medic.”
His words were careful, soothing, but his tone was smarmy. Sunstreaker’s plating crawled.
“Hmm, this field patch looks like Breakdown’s work.” The self-proclaimed medic shook his helm, examining the half-sparked weld. “Sloppy as always.”
Sunstreaker jerked in his chains, not that it helped. He was thoroughly fastened to the wall, and he didn’t have the energy to spare. “You didn’t answer my question.”
The medic looked up at him, red optics gleaming with less than reassuring intent. “You’re hardly in a position to be making demands, Sunstreaker,” he all-but-purred. “But I am a mech of impeccable manners.”
He took a step back, gesturing grandly to his own expertly polished chassis. “I am Knock Out, Lord Megatron’s personal medic.”
“Never heard of you,” Sunstreaker said.
The mech didn’t so much as skip a pulse. “No, you wouldn’t have. I don’t have quite the same reputation as a mech of your stature.”
“What the frag do you want?”
Knock Out grinned, the lecherous look spreading across his facial features. “To take advantage of an opportunity that has presented itself. One that was stolen from me so many vorns ago.”
Sunstreaker’s optics spiraled down. “What?”
Knock Out moved closer. One hand pressed to Sunstreaker’s chassis, and a single taloned digit tapped over the coarse weld. “You once had the gall to deny me. Me. A member of Cybertron’s elite and you, a lowly gladiator. I never forgot that humiliation.”
Sunstreaker shuddered, each light tap causing a spark of pain to trickle across his sensornet. “So you’re going to what? Talk me to termination?”
Knock Out laughed, his talon dragging down with an audial-cringing shriek of metal on metal. “Not quite.”
Sunstreaker pressed against the wall, but there was nowhere to go. He glared down at the Decepticon. “Is that supposed to scare me?”
“I don’t want your fear.” Knock Out’s talon scraped through dried energon, making it fleck to the floor. His hand then splayed across Sunstreaker’s ventral plating, tapping a nonsense rhythm. “I want your humiliation. So let me tell you a story.”
Sunstreaker’s HUD flashed with warning. His energon levels reached a critical point. He would need to refuel soon or he’d slip into stasis lock. The last thing he wanted was to be offline around this glitch.
“I don’t want to hear it,” Sunstreaker growled, tugging at his bonds. They rattled, but didn’t budge, firmly latched to the wall.
Knock Out ignored him, pressing closer, but not enough for their plating to make contact. In fact, the only part of him that touched Sunstreaker was the one hand. Taloned fingers continued downward, ghosting over the armor at the apex of Sunstreaker’s thighs before finally cupping his pelvic array.
“Once upon an orn there was a gladiator named Spinout. And not a very good one either,” Knock Out said, his optics burning bright and crimson as he watched Sunstreaker, the sound of a high-performance engine revving loud in the silence. “He won a few battles, but he lost many, many more.”
Sunstreaker’s ventilations hitched. How had Knock Out known his previous designation? No one alive knew that designation anymore!
Knock Out grinned, cocking his helm to the side. “How many times did they get you on your knees? How many times did they pin you down and take you?”
His hand dipped lower, bypassing the panel concealing Sunstreaker’s spike and tapping the one over his port. “How many times did you need your valve replaced, I wonder?” Knock Out asked, tracing the rim of the valve over and over with the tip of his talon. “How many seals did they break?”
Sunstreaker’s tank rolled. “You’re sick!” he spat, dread curdling inside of him.
Those memories were vorns and a lifetime ago. He had no interest in dredging them up, and was certainly not going to confirm Knock Out’s accusations.
Knock Out ignored him, his voice growing eager and thick with arousal. His energy field pulsed with it, rising up and falling over Sunstreaker in a heavy wave.
“The last one,” Knock Out continued, cooling fans kicking on with a loud whirr. “Let’s see. His designation was Double Punch, I believe. He tore Spinout to pieces and still took the time to enjoy his reward.”
Knock Out paused, fingers searching. His optics lit up when he found the manual override, forcing Sunstreaker’s panel to slide aside with a click that was ominously loud in the quiet of the brig. Apparently, the self-proclaimed medic actually did have some medical training.
“I remember watching,” Knock Out said, one talon dipping slowly into Sunstreaker’s valve, as though taking care not to damage, but still interested in exploring. “Watching as Double Punch twisted Spinout’s remaining arm behind his back and pressed him to the ground, right into a puddle of his own spilled energon.”
Warnings flashed again. Sunstreaker ruthlessly overrode them, refusing to let himself fall offline. He could feel the weakness in his limbs, however, the way the majority of his systems refused to respond. He felt numb in most places.
But his valve felt as though it were on fire.
Knock Out’s digits were skilled, knowledgeable, finding and manipulating every sensor in Sunstreaker’s valve. Rubbing them just gently enough to trick Sunstreaker’s frame into thinking this was a good thing and producing a thin trickle of lubricant to ease the way.
Knock Out added a second digit, continuing his disturbing narrative.
“Double Punch didn’t bother with preparation. He just tore off Spinout’s panel, flinging it into the crowd. Crazy mechs they were, fought over it as a souvenir.” Knock Out chuckled, dark and sly. “Spinout was too far gone to even yelp when Double Punch thrust into him. As big as Double Punch was, I’m surprised Spinout survived.”
Three fingers pushed into Sunstreaker’s valve, activating sensors, gliding smoothly in and out thanks to the addition of lubrication. Sunstreaker groaned, trying to resist the steady coil of heat in his systems.
“But he did survive,” Knock Out purred, leaning closer, his energy field buzzing against Sunstreaker’s own weak ripple, pulsing with desire and satisfaction. “And the next time he showed up in the ring, he wasn’t Spinout anymore, he was Sunstreaker.”
Knock Out’s fingers stroked in and out, putting pressure on the anterior node, making Sunstreaker’s hips jerk as the pleasure sent a jolt through his systems. He seeped lubrication, felt it dribbling down his thighs, heard it drip to the floor. His ventilations were hot and heavy, his spike thumping at its panel.
“Sunstreaker was larger, faster, stronger, and he fought with a cruelty that completely belied his earlier matches as Spinout,” Knock Out said, almost conversational were it not for the subject matter. “He was beautiful, broken like everyone else, but beautiful. He won, again and again. Like he finally understood what he’d been built for. What he was worth.”
Energy levels dipped toward stasis. Sunstreaker hung his helm, unable to spare the effort to keep it up, his systems cycling higher and higher toward overload. How he had the energy to spare, he didn’t know.
“Glitch,” Sunstreaker gritted out, his hips lifting to meet each one of Knock Out’s thrusts. His frame, betraying him, eager for that overload dancing just out of reach. “I’m going to—nngh!” He arched as far as the chains would let him, Knock Out’s fingers pressing against a sensor node and sending a sharp burst of charge along it.
“That’s better,” Knock Out murmured. “There’s no need to fight it, Sunstreaker. This is, after all, what you were made to do.”
Sunstreaker groaned, ventilations sharp and staggered. He wanted to fight, hated that he was helpless. Knock Out’s voice echoed in his audials, hypnotizing him.
Knock Out continued, curling his digits, rubbing incessantly over Sunstreaker’s sensors, lubrication dribbling down his hand.
“You were made to serve. To submit. To entertain. So do it.” Knock Out leaned forward, licking a wet stripe up Sunstreaker’s right cheek. “Overload.”
Sunstreaker’s engine revved weakly, whining in the midst of overheat. Resistance shattered in the wake of his overload, his valve cinching down, tightening around Knock Out’s fingers, milking them.
He gritted his denta, locking down his vocalizer, refusing to give Knock Out the pleasure of hearing him shout. His frame betrayed him nonetheless, writhing against the wall, rattling the chains.
“Perfect,” Knock Out said, and the click of an interface hatch opening was too loud in the brig.
Sunstreaker rebooted his optics, looking down to find that Knock Out’s spike had pressurized, seeping a pale transfluid.
Knock Out pulled his fingers from Sunstreaker’s valve with a wet noise, lubricant glistening on his talons. He curled said fingers around his own spike, a visible shudder dancing over his plating.
A hands planted on Sunstreaker’s chestplate, inches from the poorly-welded wound. Knock Out braced himself on Sunstreaker, ex-venting heavily, his taloned fingers stroking his spike, slick with Sunstreaker’s own lubrication. Judging by the sound of his engine, the swamping nature of his energy field, the Decepticon was already close to his own overload.
“Next time,” Knock Out said, his vocals spitting static, “I’ll bring my energon prod.” His optics darkened to a rust red, digits drawing inward on Sunstreaker’s chestplate, scraping off thin curls off paint and metal.
“I’ll put you on your knees,” he added, his optics spiraling in and out, as though he wasn’t quite focused on the here and now but completely absorbed in his fantasy. “Where you belong.”
Sunstreaker growled, but it lacked force. He felt weak as he hung from the chains, memory core pinging him, exhausted processor trying to tag today with images of the past.
Knock Out chuckled darkly, glossa flicking out over his lips, fingers working faster and faster over his spike. Charge crackled along his talons, the heavy tang of lubricant and transfluid thick in the air.
“You’ll probably try to fight me,” Knock Out said, talons kneading constantly on Sunstreaker’s chestplate. “And I’ll enjoy putting you back in your place.”
He leaned closer, near enough that Sunstreaker could feel the Decepticon’s ex-vents against his battered plating.
“Where you were meant to be. At my pedes.”
Knock Out’s talons snapped, piercing the outer layer of Sunstreaker’s chestplate, one gouging a sensor beneath and making Sunstreaker jerk.
“Because – nngh – you’re mine now.”
Knock Out groaned and twitched, digits squeezing down on his spike as he overloaded, transfluid spurting against Sunstreaker’s plating. It dribbled on his pelvic array and seeped into tiny gaps in his plating, dampening the circuits beneath.
Disgust coiled in Sunstreaker’s tank.
“Mmm. That was good.”
Knock Out unlatched his talons and drew back, only to lift his dripping hand and stare at it with a frown. He slapped his hand against Sunstreaker’s chestplate, smearing most of the transfluid across Sunstreaker’s chassis.
“Hmm. You’ve made a mess.”
Sunstreaker’s optics spiraled outward. He yanked at the last vestiges of energy in his frame.
“You sick fragger!” he howled, ignoring the red flashing warnings in his HUD, reminding him of imminent shutdown. “I’m going to rip out your spark!”
“An empty threat if I ever heard one.” Knock Out stepped back, his optics lingering on Sunstreaker’s frame. “You should clean up nicely. Once you earn it.”
Sunstreaker growled, digits curling into angry fists. His processor spun, circuits misfiring. He watched as a countdown popped up in the corner of his HUD, giving him thirty kliks with no possibility of override.
“I’ll be back tomorrow,” Knock Out said, interface panel sliding shut with a loud snick. “Try not to miss me.”
The last thing Sunstreaker saw was Knock Out’s smirk before his system crashed and the world went completely dark.
The voice filtered through to Sunstreaker’s audials. He onlined with a startled huff of his vents, cold water streaking down his armor and into the gaps of his plating. His circuits cringed at the abrupt temperature change. His systems pinged his status automatically: fuel levels at 20%.
The Decepticon had refueled him, but only to just above the minimum.
Sunstreaker fought back a groan, wrists twitching but getting nowhere, still chained to the wall as they were. The same for his pedes. He onlined his audials, and snarled when the fuzzy shape in front of him clarified into the grinning visage of Knock Out.
“Recharge well?” Knock Out asked, all fake-cheer as his palm landed on Sunstreaker’s chestplate, energy field a burr of eager anticipation.
“Rust in the Pit,” Sunstreaker snarled, though it was half-sparked at best. His joints ached, the water caused his sensors to go haywire in an unpleasant manner, and his tanks gurgled at him.
Knock Out chuckled. “There’s so much fire left in you. Good. I like that.”
Sunstreaker’s optics cycled down, but he said nothing, the anger festering inside of him like a bad case of cosmic rust.
“Since you enjoyed our last encounter so much, I thought it only polite to offer my services again.” Knock Out gestured with one hand, fingers curved in a come-hither motion. “I do so despise a flashier paint job than mine. Lucky for you, this is no longer a problem.”
Sunstreaker’s engine revved. He kept his silence. His yelling only seemed to goad the sadistic medic on.
“What? You have nothing to say?” A mock pout curled the Decepticon’s lips. “You were so much more interesting yesterday.”
His digits curled into fists. The trickle of the water was maddening.
Knock Out shook his helm, one hand sliding down Sunstreaker’s chestplate, warm compared to the chill of the water. “Oh, well. I suppose I’ll simply have to make do.”
The hand continued to roam, trekking over Sunstreaker’s plating, dipping into joints and seams, as if taking the Autobot’s measure.
“Whoever designed your rebuild did an excellent job,” the Decepticon purred, optics brightening as his fingers swept over dented and scored armor. “Redundant systems. Double plating. Reinforced joints. You can take a hit and keep on coming. I like that.”
Sunstreaker pushed back against the wall, though it did little to put any distance between himself and his tormentor. “Are you that hard up for an interface?” he snarled as charge crackled from his plating and seeped out from between his seams. “Or is it that not even your fellow ‘Cons want you?”
Knock Out laughed, not a trace of offense in his rippling energy field. “If you were trying to insult me, you’ll have to try harder.” One hand dipped lower, cupping Sunstreaker’s pelvic array. “I seem to remember you enjoying my advances just yesterday.”
“Enjoy is not the term I’d use.”
“Mmm. Now there’s the resistance I was looking for.” Knock Out’s optics brightened as he pressed closer, hot ventilations wafting over Sunstreaker’s plating. Heat emanated from the Decepticon, the low pitch of an idling engine filling the brig.
His fingers found Sunstreaker’s interface, tracing the panels that protected his spike and valve. The fine-tipped digits circled the delicate seams, stimulating the sensors ringing the release mechanism.
Sunstreaker ground his denta, refusing to respond. It felt good, but only in the sense that any sort of proper stimulation would alight his sensors. It didn’t mean he wanted Knock Out anywhere close to his valve.
“You heat up so quickly,” Knock Out murmured, continuing the slow, methodical stroking, enough to cause heat to pool in Sunstreaker’s interface. “Proof positive that this is your primary function. To satisfy your betters. A berth toy for our pleasure.”
Sunstreaker’s engine clunked to life, not out of pleasure, but out of anger. Yet, he kept his silence, letting that speak for himself.
“Don’t you agree?”
Sunstreaker glared, putting as much hatred and loathing behind the brightness of his optics as he was capable.
Knock Out didn’t so much as cycle his optics. “Of course you don’t,” the so-called medic simpered. “But you will soon enough.” He undulated against Sunstreaker, their plating brushing lightly enough to draw charge but not streak paint.
“And as for this…” Knock Out’s fingers curved around the leading edge of Sunstreaker’s interface panel. “Well, you won’t be needing this anymore.”
Sunstreaker’s optics rounded. He sucked in a ventilation, but before he could so much as work up proper vitriol, Knock Out gave a sharp yank, pulling off his panel. Sunstreaker shouted, hips arching away from the wall as pain radiated outward from his pelvic array. Knock Out tossed the panel over his shoulder where it clattered away in the dark.
“Oh. Did that hurt?”
Sunstreaker worked his jaw and mustered up a glare. “Tickled,” he gritted out, the hydraulics in his legs trembling as he unconsciously tried to protect his sensitive components, but the shackles prevented him.
“Then you won’t mind if I take the other one as well.”
A growl rattled in Sunstreaker’s chassis. It did nothing to stop the Decepticon from hooking his digits in the panel protecting his spike and ripping it away. Tepid air wafted over his naked components, doing little to ease the acid-like sting.
“Hmm. I am curious as to what design you carry,” Knock Out said. The pad of his thumb brushed over the head of Sunstreaker’s recessed spike. “No doubt it is as wonderfully crafted as the rest of your frame.”
Sunstreaker shuddered. His hips pushed toward Knock Out’s touch without his permission. Stimulation was stimulation, but it didn’t stop his frame from crawling.
“Flatter me all you want,” he spat, tanks churning in their barely fueled state. “I’m still going to rip your helm off when I get free.”
Knock Out chuckled and stepped back, putting a mere pace between them. “Mmm. Now won’t that be interesting to watch you try.” He put his hands to his chin, optics flicking up and down Sunstreaker’s frame. “Until then, however, we should try and have a little fun, don’t you think?”
He reached for his hip, disengaging a weapon that Sunstreaker cursed himself for not having noticed before. It was, for the most part, innocuous in appearance. A slim metal rod, barely the length of Knock Out’s forearm. But with a flick of his wrist and a touch of his finger, the rod extended until it was Knock Out’s height, electricity crackling from the two-pronged tip.
An energon prod. Wonderful. The fragged sadist had an energon prod.
“I am sure you know what one of these are. They make for decent weapons, if you know how to wield them properly.” Knock Out smirked, casually flicking the prod from hand to hand. “Which of course I do.”
Sunstreaker’s optics cycled down. “Is that supposed to scare me?”
“I suspect you’re too stupid to fear much of anything. That doesn’t mean I’m not going to keep trying. I have a kink for lost causes.” Electricity sparked and spat at the tip of the prod, activated by a flick of Knock Out’s wrists. “Have I mentioned how strongly built your frame is?”
Sunstreaker ex-vented. This was not going to be pleasant. Torture was nothing new to him. If Knock Out thought a little shock and some rape was going to break him, then obviously he didn’t remember as much of Sunstreaker’s gladiating past as he thought. He’d survived it then and he would survive it now.
The teasing glint left Knock Out’s optics as he twirled the energon prod again before facing Sunstreaker.
“I know you can take some damage,” he said, vocals huskier than before, his energy field radiating eager anticipation. “Let’s see how long it takes before you scream.”
“Never.” Sunstreaker would cut off his vocalizer before he’d allow Knock Out to see him squirm.
Knock Out smirked. “We’ll see.”
He thrust his arm forward, the crackling energy coming into direct contact with Sunstreaker’s chestplate.
It was normally one of his better armored sections. Sunstreaker gritted his denta as searing charge lit across his sensory net. Knock Out had aimed for the weld lines in his chassis, which were a direct course to his substructure.
Sunstreaker grunted, writhing in his chains. His plating scraped against the wall behind him. The odor of scorched circuitry filled the air.
Knock Out laughed and withdrew the prod.
“Now that was enlightening.”
He paced back and forth in front of Sunstreaker as though searching for the best place to attack next.
Sunstreaker’s chassis heaved, ventilations coming in short bursts. It would have been easier to bear if he’d been fully fueled, completely repaired, entirely rested. But the dizziness in his processor seemed to make the pain sharper, the overcharge more intense.
Frag the Decepticon to the Pit and back!
Static crackled and hissed from the prod as Knock Out waved it through the air, a hypnotizing pattern in front of Sunstreaker’s optics.
The prod came close again, charge lessened but still dangerous. The very tip caressed the distant edge of Sunstreaker’s armor, and then dragged down his side, catching on the edge of a lateral seam and leaving scores in his plating. He went rigid, bracing himself against the crackle of electricity as it tunneled under his armor, lighting across his circuits.
Pain. Everything devolved to pain. Sunstreaker couldn’t think about anything else. Systems redlining, HUD screaming warnings at him, the searing agony of circuits overblown and smoking.
Knock Out drew back, and Sunstreaker sagged from sheer relief.
A relief that was very short-lived. The narrow gaps in his pelvic armor, designed to give him better freedom of movement for his legs, were much too tempting. Knock Out struck first one and then the other, ramping up the voltage. Sunstreaker’s lower extremities jerked a strange contortion.
Pain. Nothing but pain. And the sound of Knock Out’s labored ventilations, brought upon by his arousal. The overwhelming push of Knock Out’s energy field battered at Sunstreaker’s own weakened state.
The prod continued its swath of pain, sweeping over Sunstreaker’s pelvic array, snaps of charge tunneling into his interface. His entire frame arched, desperate to get away from the weapon and helpless in the wake of it.
Electricity snapped over Sunstreaker’s armor. The prod poked at his knees, down toward his pedes, seeping into the intricate mechanisms of his ankles.
Arousal pulsed heavily in Knock Out’s energy field. His optics were a bright crimson, his glossa slipping out over his lipplates. Fragging sadist.
The energon prod wandered over Sunstreaker’s armor, causing both damage and agony. Sunstreaker gritted his denta, grunts escaping him. He refused to cry out, to give Knock Out the scream he wanted.
“I honestly can’t decide which is more intoxicating,” Knock Out said, his vocalizer laced with static. “The way you silently resist me, or the challenge of making you scream.”
Knock Out’s interface panel snapped open. He reached down with his free hand, curling his digits around his spike, a shudder visibly wracking his frame. Transfluid seeped from the tip.
“Perhaps it’s both.” Knock Out stroked his spike with measured pulls of his hand.
Sunstreaker cycled his vocalizer, engine revving a distressed rumble. “Do you brag just to hear yourself talk?”
Knock Out’s response was to drag the energon prod over Sunstreaker’s right leg, where a hastily done weld gave way to a special kind of agony. Sunstreaker’s entire frame went rigid as he struggled to keep his response in check, refusing to give Knock Out the pleasure. His systems redlined, warnings popping up left, right, and center.
His leg spasmed, circuits giving out with a smoke-spewing pop. His paint bubbled up and peeled away as Knock Out turned the current up to its maximum potential. Sunstreaker groaned, long and low, an ill sound, spark spinning faster and faster in his chassis.
Knock Out jerked back suddenly. Sunstreaker lost the battle with his hydraulics, every cable going limp, leaving him hanging from the chains in such a way that his shoulders were stressed by the additional weight. Strength bled out of him as his optics flickered, and his systems tried to reset. The scent of charred lines and scorched circuits burnt his nasal ridge, and the disgusting odor of boiled energon joined the stench. He was never going to be pristine again.
“Well.” Knock Out flicked off the energon prod and tossing it aside. “That wasn’t a scream but it’ll do for now.” He stroked his spike again, taking a step closer to Sunstreaker.
His free hand lifted, fingers dragging down Sunstreaker’s faceplate in a parody of a lover’s caress.
It was hard to think, harder to focus, and Sunstreaker couldn’t muster up the energy to jerk his helm from Knock Out’s unwelcome touch. He was exhausted, and his tanks kept pinging back a reading of fifteen percent, barely above functional.
“I did have plans for your valve,” Knock Out said, his hand wandering down and pushing a single digit up into Sunstreaker’s dry valve. “But I’m a bit too impatient for that today, I’m afraid. I’ll have to settle for a substitute.”
What the frag was that supposed to mean?
“Don’t worry,” Knock Out’s touches withdrew as he stepped away. “We’ll get to that soon enough.”
Knock Out headed for the mechanism that controlled Sunstreaker’s restraints. He highly doubted the Decepticon planned on freeing him, a doubt that was proven when whatever Knock Out did loosened the chains but didn’t release the manacles. Slack was given to the restraints on Sunstreaker’s arms, but his legs couldn’t support his weight. He dropped to his knees, biting his glossa on the cry of pain that attempted to break free.
“There. That’s better.” Knock Out’s smug tone filtered through to Sunstreaker’s audials.
It took effort to lift his helm, unsurprised to find the Decepticon standing right in front of him. On his knees, Sunstreaker found himself staring at Knock Out’s spike, transfluid seeping from the tip in eager dribbles.
Sunstreaker growled. “You can’t seriously think I’m going to cooperate.”
One hand wrapped around his spike, Knock Out smirked. “I know you’ll cooperate,” he said, and he leaned closer, free hand grasping Sunstreaker’s face firmly. “If those denta so much as scrape my spike, I’m going to rip yours off. Understood?”
His optics cycled down, glare firming. Cooperate or lose his spike? For all he knew, the Decepticon would yank it off anyway.
Knock Out’s grip tightened, stressing the dermal metal of Sunstreaker’s face. “The chronometer is running, my pretty toy. Do we have an understanding?”
The shudder that rippled across Sunstreaker’s plating was spark deep.
Knock Out inclined his helm. “Good boy,” he said, and caressed Sunstreaker’s face before letting it go. “Now say ahhhh.”
He might not bite the fragger’s spike off, but like the Pit he’d make it easy!
Sunstreaker clamped his mouth shut, the overwhelming scent of transfluid filling his olfactory sensors.
“You’re going to be stubborn about it?” Knock Out grabbed Sunstreaker’s helm. “Have it your way.”
He thrust his hips forward, the head of his spike nudging at Sunstreaker’s mouth, smearing transfluid over his lips. One hand grasped Sunstreaker’s chin again, pushing his thumb up toward Sunstreaker’s mouth, narrow talon slipping between his lip. The dermal lining tore and energon welled free.
Frag, no, he wasn’t going to make it easy.
Knock Out pushed his spike against Sunstreaker’s mouth, pried his lips apart with two sharp talons, and thrust inside with a self-satisfied burst of his energy field.
Sunstreaker’s tanks rolled, his hands pulling into fists. Knock Out didn’t bother with a slow acclimation. He shoved deep, the head of his spike knocking against Sunstreaker’s intake. His olfactory sensors were overladen with the scent of expensive polish, transfluid, and heated metal.
“Yessss,” the Decepticon hissed, fingers flexing on Sunstreaker’s helm as he unhooked a talon from Sunstreaker’s lip. “Not as good as a valve but a decent substitute.”
Did he ever stop talking?
An aroused shiver danced over Knock Out’s plating, which lifted to expel some of the heat emanating from his frame. It wafted over Sunstreaker’s over-sensitized armor, battering against fried sensors and circuits.
Sunstreaker’s glossa was jammed at the base of his mouth. He couldn’t do much more than twitch it against the Decepticon’s spike. Not that he wanted to cooperate, but the sooner he got the Decepticon off, the faster Knock Out would leave him in peace.
He shuttered his optics. He might have to suffer the fragger’s spike in his mouth, but that didn’t mean he had to look at him.
Knock Out grasped his helm in both hands, a huffy ventilation expelling from his frame. “Very nice indeed,” he murmured, and moved his hips in tiny circles, as if trying to paint the inside of Sunstreaker’s mouth with his spike.
A growl of disgust vibrated through Sunstreaker’s chassis.
Amusement rose in the Decepticon’s energy field. His fingers stroked Sunstreaker’s helm, a mockery of a lover’s encouragement.
Knock Out’s laughter burbled up, though it was rasped with static. “Don’t worry. You’ll get to taste your master soon enough.”
Disgust welled up in Sunstreaker’s energy field, which rose up in fits and spurts, heavily dampened by his lack of energy.
Knock Out started to move, sliding out of Sunstreaker’s mouth before pumping his hips forward again. It was a slow, measured rhythm that nonetheless had the Decepticon’s ventilations quickening. Every so often, Knock Out’s spike would bump the back of Sunstreaker’s intake, making his tanks churn.
Sunstreaker felt Knock Out shiver. The way the spike subtly swelled in his mouth, pre-overload transfluid trickled down his intake. The urge to clamp down with his denta came and went, the threat of a rather painful mutilation lingering at the back of his processor.
Knock Out’s thrusts picked up in pace, his fingers clamping down as opposed to stroking, ventilations coming faster and faster. Heat poured off of him, blasting Sunstreaker’s faceplate. He was close, had to be–
He stopped. His engine whined, systems stalled.
“Frag it all to the Pit!” Knock Out snarled and went still, one hand rising to his helm. “This is Knock Out, sir.”
Knock Out huffed a ragged ventilation as he took the call, no doubt responding internally. Sunstreaker could only wait as the spike throbbed in his mouth, and Knock Out’s talons dug deep.
Knock Out’s thrusts returned in earnest.
“He has the absolute worst timing,” Knock Out muttered and pumped his spike in Sunstreaker’s mouth several more times before he stiffened from helm to pede, pushing his spike to the back of Sunstreaker’s intake.
He braced himself as several spurts of hot transfluid hit the softer metal in his intake, the hot metal scent of it filling his olfactory sensors. Knock Out groaned a long and low note, only to suddenly withdraw, the last few spurts streaking across Sunstreaker’s faceplate.
He coughed before he could stop himself, trying to dislodge the cloying globs of transfluid clogging his intake.
“You look better this way. Transfluid suits you,” Knock Out said, giving Sunstreaker’s helm a light pat.
Sunstreaker jerked away, engine churning as it struggled to online. He spat up another clump of transfluid, but it failed to meet the mark, falling short of landing on Knock Out’s pedes. He turned his helm, wiping his face against his arm, but it did him no good. He could still feel the transfluid, tacky on his plating.
“How rude of me, to have to leave you unsatisfied.” Knock Out rooted around in his subspace and produced a rather intimidating object. “This should suffice in my absence.”
Sunstreaker snarled, pushing back against the wall, but his legs refused to respond. The motor cables had been thoroughly fried by the Decepticon’s prod, frag it! “Keep that thing away from me!”
“My, aren’t you ungrateful.” Knock Out’s smirk widened as he crouched in front of Sunstreaker, unceremoniously sticking his hand between Sunstreaker’s legs.
He twitched his hips, trying to avoid the Decepticon, but it was pointless. The false spike shoved into his valve without any preparation, too thick to be comfortable, and ridged with thick nubs that prodded at the walls of Sunstreaker’s valve. He stifled a grunt.
“Hmm. I suppose I shouldn’t have torn off your panel,” Knock Out murmured, tapping his chin. Another push shoved the toy further, the head of it knocking against a ceiling node. “No matter. Easily fixed.”
Knock Out rose to his pedes, searched the floor, and returned with Sunstreaker’s dented panel in hand. Sunstreaker read his intentions even before Knock Out’s free hand shifted into a micro-welder. Sunstreaker tried to angle his hips away, an impossible venture without use of his legs.
“Ah, ah,” Knock Out said, shaking a finger at him. He crouched once again, reaching for Sunstreaker’s interface. “You want I should miss? Weld something that shouldn’t be welded?”
It wasn’t like he had a choice.
Sunstreaker had thought himself numb. He was quickly proven wrong when Knock Out started to weld, without bothering to sedate him or turn off his pain receptors. Sharp agony coursed through Sunstreaker’s interface, like someone had poured acid over his lines, and a pitiful whine escaped him before he could stop it.
Chains rattled as Sunstreaker yanked on them, helm lolling backward against the wall. He couldn’t move, couldn’t think, couldn’t stop the pathetic churning of his engine.
“There,” Knock Out said, a self-satisfied purr to his energy field. “Good as new. Or close enough.”
Sunstreaker’s processor spun. He couldn’t form words, much less dredge up the energy for a glare. Knock Out’s vocals floated in and out of his audials.
He shifted as much as he was able, and the toy within him shifted as well. The thickness of it rubbed against the lining of his valve, scraping the dry walls.
Knock Out half-turned, optics gleaming with malice. “Oh. Before I forget…”
Sunstreaker’s ventilations gasped, his entire frame bucking as the device in his valve suddenly buzzed to life. Vibrations pulsed across his sensitive components, stimulating the sensors lining his valve. No node was left untouched, burying him in wave after wave of circuit-sizzling charge.
“Don’t worry. I’ll be back soon enough.”
Sunstreaker’s servos clenched into fists. He barely noticed when Knock Out left the cell, abandoning him to the onslaught of the device.
Knock Out fought off a shiver of unease as he stepped onto the bridge, still smelling of transfluid and overloads. Lord Megatron’s summons had left him no time to clean up. A few stray streaks of gold had unfortunately wandered to his paint. It was a sight most unseemly.
