Chapter Text
...
You stole my light, my pride, my sight,
And now I want forever to hide my plight.
Yet, no matter how soft or how kind,
To IT I will always sing a sad lullaby.
…
They were supposed to be catching Wasp not a … juiced up stereo with legs. Not that it mattered now, the two of them chained to the ceiling, systems out of sync because of some sonics the visored freak had thrown their way. Sentinel Prime’s internal systems still felt scrambled and his equilibrium was all but gone causing him to be as weak as a sparkling. It was a disconcerting feeling that stirred the contents of his tank, yet he wanted to keep his fear well masked and so Sentinel Prime resisted the urge to release his tanks right then and there.
He didn’t want to look weak. Not in front of Optimus. He was the superior officer after all, and Elite regulations told him that panicking was the worst thing to do in a captive situation. And Sentinel had always prided himself for being a stickler for the rules. Besides, he would never let Optimus think he was stronger than him. He was stronger than that glory hound, that coward.
He wouldn’t have let her die…
Dreams were rare already for a transformer, but his dreams… were always of her, reaching for him, crying out for him as she fell.
Elita…
Shaking his head, hating how being around Optimus was bring forward old agonies, Sentinel shook his head to regain some equilibrium. She was deactivated after all and so should his want for her. He needed new dreams and new wants. Like … like … He wanted to be Magnus. Yes, that was his longing now. It was his to-be lover, especially when it was something that could not die. A title cannot be lost or hurt … just tarnished and traded.
A secret part of Sentinel thought of that goal as his only purpose now. It would be his love. It would bury his old hurts as well as the thought of the bonding ring in his subspace that he could never take out. He had bought it for Elita-1 shortly before the incident, waiting to ask her to be his until after they graduated.
A day that never came.
And that thought made him sick.
“Your tank bothering you? Mine sure is after that … sound weapon,” murmured Optimus, energon pooling down the side of his head from a wound as he stared at his strangely silent superior. Optimus Prime hadn’t gone down as easily as Sentinel had because he had dealt with Soundwave before, so he had been beaten down for it.
Sentinel glared, recalling the battle. From what he was able to recall, Optimus knew their attacker calling him Soundwave or something. As usual, it was Optimus’ fault. At least he hadn’t been as cowardly as he had been with the giant spiders.
I want to hate him!
But no, that was wrong. He was a superior officer here and had an honor code. Therefore, an officer obeyed the rules and a loyal Autobot couldn’t think that way. Nonetheless, those kinds of thoughts were always there, spitting out of his vocals like venom in taunting little phrases here or there.
Dimming his optics, protecting his pride because he would never just be a lowly construction-bot like his sire (like Optimus was right now), Sentinel glared for a moment and grumbled, “My tank isn’t bothering me. My equilibrium systems may have been damaged otherwise I would already have us out of here!”
Optimus frowned and pulled at the chains that had him hanging off the floor by a few inches, his peds twitching as he struggled to touch the ground and get some leverage.
Glaring at the chains around his wrist for a moment, Optimus sarcastically replied, “I’m sure you would have, but since you can’t… help me think of a way out of this. Soundwave was a little weird this time and I don’t want to know what he has planned.”
Raising a metallic brow, Sentinel was almost afraid to know what Optimus considered weird but found himself asking anyway, “What do you mean by weird?”
Tugging on his chains as he tried swinging, Optimus grunted, “Well, he said something about Soundwave will be superior and not is superior like he would usually say. He then tried plugging into my systems by bashing my head into the cement a few times and sticking a tentacle … ugh … thing under my helm. My security systems were saying he was trying to get to my schematics.”
Sentinel’s optics went wide and he found himself barking, “What?! Which schematics?! Those are planet secrets, Optimus! You could be labeled a traitor if you gave those away!”
Giving a pointed look, his EM field burst in irritation, the fire truck murmured, “I didn’t give him anything. He took them, I think. I kind of passed out.”
“You what?! You don’t even know what he specifically took?!” yelled Sentinel, not wanting his name to be associated with the mech that revealed Autobot secrets, accidentally or not.
Finally looking a little bit angry at the accusations, Prime barked back, “At least I fought harder than you! You were out after the first hit!”
“Are you saying my melee skills aren’t up to par!?”
“Yes! Yes, I am saying that!”
“Oh, I’ll have you court martialed for insulting a superior officer!”
“The only thing superior about you is your bad attitude, Sentinel. You have always been a jerk, but you used to know when to lay off. Now lay off! Before Elita deactivated you… what’s that?”
Optimus suddenly went still, his head jerking to the left and revealing the ghastly truth of what Soundwave had done. Sentinel’s rage deflated for a moment at the gore as he shrank back at the sight. Something was still attached to Optimus’ helm, like a radio transmitter or something. That didn’t stop him from barking though, Elita’s name pressing at his mind, “What were you going to say?! Out with it, Optimus! And what is that thing attached to your helm?”
Optimus turned to glare at the loud mouth Prime and murmured, “Quiet, I heard something?”
“Oh, don’t try to get out of this! I was talking to you! What were you saying about Elita!”
“Loudmouth: annoying,” came a static-filled robotic voice as a blue and bulky form wandered out of the shadows to look over the two Primes like they were little more than hanging meat.
Sentinel glowered at the intruder and Optimus frowned, the latter murmuring, “Soundwave, why are we here? What do you want with us? Let us go!”
The Decepticon tilted his head and came forward. Staring for a moment before he slowly reached a hand forward, running his hand over Optimus’ jaw and making the mech jerk back. Soundwave merely stood there in front of the two undeterred, staring at the energon that was now on his hands. The implantation was still bleeding. The blue mech frowned behind his visor as he stared at the blue glow of Optimus’ energon. He knew all too well that his fluids were not the same color and that bothered him.
Bringing his hand down, he said with the same toneless voice, “Knowledge: required. Structure is superior: rust-less and timeless.”
Optimus’ optics widened. Seeing the Con in the light for the first time now he noticed there were red patches on his armor, probably from hiding out in the sewers. It was rust. He must not have been made very well and though the rust was minor, it seemed far too accelerated from being down in this wet place.
In fact, it was so accelerated, it was like it was a disease or a chemical he had gotten into. Soundwave was made of soft earth materials after all. He had originally been a child’s toy, so it really shouldn’t have been that much of a surprise.
Regardless of the initial shock from Optimus, Sentinel seemed to realize what was going on without Optimus having to clarify. “Frag, no! We are not going to give a known criminal our schematics or metal! I don’t care if your offlining. It’s against regulation and we won’t tell you anything … though if you surrender yourself and release us, medical care is offered to all prisoners. So, release us!”
Looking at the loud mouth for only a moment, the musical menace turned his attention back to Optimus and murmured, “Initial statement: inaccurate. Not we… Optimus Prime will help me. He will help me disassemble the blue one’s structure and then I will rip into you.”
Optimus’ EM field recoiled at the thought, barking, “What?! I’m not going to help you … even if Sentinel kind of deserves it.”
Sentinel’s mouth dropped open as he stared at his ex-friend. “What did you say?!”
Red visor glowing for a moment in irritation, the Decepticon reached towards Optimus and tapped the small receiver now attached to the mech’s helm, “Choices: none. You will assist me.”
Sentinel could only watch in helplessness as Optimus suddenly withered like a fish on a hook. The blue Prime didn’t know if he should be more afraid of whatever the Con was now doing to Optimus or what the visored mech was planning for him.
Not that it mattered, because a klick later Optimus stopped withering like his motherboard was being barbecued and turned a dull almost passive gaze to Soundwave, murmuring, “What do you require of me, Master?”
With a suddenly hammering spark, Sentinel then watched as the Con walked over to a nearby wall and loosened the chain suspending Optimus off the ground. The red Prime fell to his feet with an uneasy balance, still dazed looking. He didn’t even twitch or strike out when the cuffs around his wrists were removed and fell slowly to the floor noisily. Then, with calm hands, Soundwave started touching the side of Optimus’ helm again, almost longingly feeling the metal of the other mech’s face as the Autobot stared passively at the concrete wall. They were most likely in a room that once belonged to the subways or sewers.
Feeling a slight protectiveness, his mind telling him it was because he was a commanding officer here and not because they were old friends, Sentinel barked, “What the pit did you do to him?! You … stop touching him! Don’t you dare touch a circuit in his body or you will fall under the full punishment of Autobot law!”
The petting suddenly stopped and then the visor turned to Sentinel, Soundwave booming, “Silence: It will be obtained either way, even if I have to take both of you apart.”
Puffing his chest out as well as he could while hanging there like a piece of meat on a hook, Sentinel barked, “Frag you! I’m not a traitor or a weakling! Whatever you did to Optimus Prime won’t work on my CPU! I have more security in mine then the glorified repair-bot!”
The sound-mech was about to retort but stalled. He didn’t know that word, frag, and if he was going to successfully infiltrate the Autobot ranks in order to get ahold of that key or a shard of the Allspark in order to get his own spark, he had to know at least the basic jargon. Turning to the dead-opticed Prime, Soundwave asked, “Optimus: What is frag?”
Sentinel couldn’t stop the blush on his metallic cheeks as mind-zombie Optimus, who was now sitting on the floor looking up at the blue mech with pouty lips, stated in an airy voice, “It’s a way for mechs and femmes to pleasure each other and to make a carried Cybertronian, also known as sparklings. It is used as a flexible insult as well.”
The earth-made mech looked confused, murmuring in a softer tone than usual, “Inquiry: How do they pleasure each other?”
Blinking his half-lit optics, the Prime continued, “Well, one uses their valves and spikes. Femmes naturally only have valves while mech’s have both a spike and a valve. Said parts are then used to interlock, arose and exchange fluids. The pressing of sparks, spark rubbing, with this giving of transfluid, or nanites, into a port can then make a valve taken mech or femme spark and be with sparkling. When that happens, they are called Heavy.”
Visor becoming bright, his mind wanting to know all it could about the body he would soon own if everything went right, Soundwave asked, “Sparkling?”
“The equivalent of a baby,” answered the Prime as if knowing that dead tone was a question.
Still confused, the Con waved his hand over Optimus’ body unsure of where the equipment was even located as he asked, “Command: Show me.”
Before the higher ranking Prime could even avert his optics because he did not want to see that, Optimus had popped his codpiece and there was a clang as the metal hit the floor. Then, with a quickness one thought the zombie-Optimus probably shouldn’t have possessed, the repair-bot was suddenly lying down on his back and spreading his legs like a pleasure bot so the Earth-mech could get a better look. Then, to make matters worse, Optimus stuck a finger in his valve and pumped it once in his likely popped valve with how far that finger was going in. “This is my valve, Master Soundwave.”
Then, not even skipping a beat, he rubbed his thumb over the bump that housed his metallic spike only to have it suddenly spring out. The visored mech actually jumped a little in surprise as Optimus explained in that same airy tone, “This is the spike. Another mech’s spike goes into my valve or my spike would go into another’s Cybertronian’s valve.”
Staring at the member for a moment before he reached out a calm hand and poked it, Soundwave nodded in acceptance. The scientific part of his processer probably coming from a learning program his father-scientist had felt necessary to add for Sari’s education. Then, probably still in science mode, curiosity elated, Soundwave asked, “Show me this … fragging?”
Optimus looked confused until the earth-mech pointed at the chained Sentinel, adding, “On him.”
“What?!” squawked Sentinel, a new fighting vigor in his still sluggish systems, “No! No! No! I am a femme kind of mech. I do not do other mechs and I especially don’t have other mechs do me! Optimus! As your commanding officer, I order you to put your codpiece on and stop this!”
“Silence,” said the monotone voice that echoed through Sentinel like a volt of electricity causing the cocky mech to snap his mouth shut for a minute, fear suddenly seeding in his spark. This was getting really dangerous. He was helpless and disoriented and Optimus was … a zombie.
He had had better days.
Nodding to Optimus, the intrigued Earth-mech turned back to his pet and asked, “How … does one start?”
Optics still white, Optimus replied, “Foreplay, which is the touching of the chosen partner to get them aroused, especially the valve barer that will be penetrated. They must be wet so it doesn’t hurt and so that friction is easily created.”
Sentinel didn’t like Soundwave’s next words at all, “Start: Get the other Prime wet.”
Voice still struggling to gain its usual vigor, the usually confident Autobot blubbered, “N-no. I’ll-I’ll fuck Optimus’ valve! Don’t let him touch mine! In fact, I-I demand that no one frags. Can’t you just try to kill us like a normal Con?”
Soundwave stared at the blue Prime for a moment and then dully replied, “I am not a normal Decepticon. Optimus Prime: Obey.”
“What?! I said no!” squeaked Sentinel, his EM field pulling in close. “And why my valve?!”
Cocking his head as if confused, Soundwave stated, “Optimus said friction is required. Optimus Prime unchained: he can reach maximum friction inside your valve.”
Sentinel almost felt sick with what phrase, his valve twitching in excitement despite his fear. It never got any attention. Never. It hadn’t even been popped since he had never … been with another mech. He prized its disuse greatly because it meant that he was successful in the berth. He only got femmes and was always the dominant partner.
It wasn’t the pain of the popping he was afraid of. It was the shame at his loss in sexual status.
In fact, he was so horrified by the thought of losing his sexual prowess that he actually screamed when Optimus touched his leg, the firetruck having shifted forward on his knees toward Sentinel. The truck-former looked up in surprise and then gave a puppy dog pout as if he had been kicked. Sentinel almost, almost, felt bad for pressing away.
Optimus always had really nice lips.
W-why had he just thought that! Damn valve!
Unfortunately, Soundwave was intrigued and had little patience now, “Chained: Take him.”
Optics going so bright that Sentinel was sure something melted, the blue Prime actually squeaked, “What?! Y-you are going to make the repair-bot rape me?!”
Soundwave, if he had a month, might have frowned in confusion. Then, tilting his head away from the panicking Prime, the overgrown radio looked down at the docile Prime and asked, “Inquiry: What is rape, Optimus Prime?”
Rubbing Sentinel’s leg, not dissuaded by the other’s whimpering or tight EM field, Optimus started rubbing his lips against Sentinel’s inner thigh even though Sentinel was crying out as if burned. Optimus then moved his head up and kissed the other mech’s codpiece before he answered the inquiry, “The taking of sexual pleasure forcefully without the other partner's complete consent.”
His mind ticking for a moment, the Con replied, “Conclusion: Then rape him.”
Optimus smiled. If he was because he was excited at the prospect of raping his ex-friend or because it would please his Master, Sentinel never wanted to know, though his nightmares would always be of Optimus smiling up at him, telling him his valve tasted good and how he was going to enjoy ripping it for orns to come.
The first tear came when Optimus was finally able to jimmy Sentinel’s codpiece off and almost lovingly took to kissing his sheathed spike. Said little kisses then headed downward until he met the rim of the valve where he placed the most gentle of pecks, whispering something to it with a heated breath from his mouth vents. It was probably something like, ‘Hello there’ or ‘Your beautiful’ or ‘Lovely’ but it didn’t really matter to Sentinel when Optimus almost barbarically forced those thighs apart and like a wild animal stared licking that valve, deaf to Sentinel’s first, “Don’t!”
Many cries like that followed after. It was probably music for the Con because Soundwave nodded in approval as he perched himself on a crate. He even took out what looked like a guitar and waxing rag, watching almost thoughtfully as Optimus gripped the blue mech’s aft, the other hand continually reaching upward and feeling for seams in the chassis.
Sentinel’s commands and threats only lasted for about five klicks until the desperation set in, the truth setting in. This was happening. This was going to happen. He was going to be raped but his ex-friend.
“Optimus … unnh… please … stop,” whimpered Sentinel as he looked down at the helm between his legs, the helm bobbing as the other mech lapped at his valve like a hungry turbo-fox. He could already feel oral fluid dripping down his thighs, getting him wet.
Sentinel had to look away in horror. True, he went down on many femmes in his time but this felt so dirty… so wrong. But, despite the sickness forming in his tank, he suddenly shivered hard as the lapping suddenly turned into sucking, those pouty lips suddenly pressed around the port as if trying to suck the air out of the blue Prime's very carrying chamber.
The blue mech immediately arched, his valve rippling in appeasement. Sentinel choked, “Oh, Primus.”
Soundwave just titled his head, watching as the blue Autobot started withering in his chains, whimpering and bucking while trying to not look down at the helm that was bobbing between his legs and sucking like a sparkling to a feeding tube.
Vocals tight because he knew a moan would escape him, all Sentinel could do was shake his head. He didn’t want his first valve-gasm to come this way. He didn’t! He didn’t want it to belong to Optimus Prime. Pit, he never wanted one to begin with. Once you were popped, it was like femmes could smell it and wouldn’t be interested.
Femmes liked their mechs to be alpha mechs, not catchers.
Pushing down any daring whimpers, Sentinel gained his voice as he looked down.
“T-this has gone on long enough! Stop! Stop! Stop… oooh, ugn, eh,” his wiggling only made Optimus grab his aft tighter though, purring into his valve, unconcerned with the other’s crying.
Sentinel, at the purring vibration, suddenly found himself pressing into the face of the other mech in reaction. He was coming. Oh, Primus above, he felt his whole valve getting tight as a tingle started in his gestation chamber and traveled downward. Then, just as a wet tongue pressed inside him and up toward the inward seal, he felt an exploded inside. His valve rippled as his first valve orgasm occurred, shivering and clutching at the lips that were sucking graciously at the hungry little hole.
Head threw back, optics going white for a moment, Sentinel wasn’t sure if the spasming of his valve walls lasted for five klicks or a groon. Not that it mattered, Optimus just kept sucking as Sentinel panted and whined, not even noticing how the blue Prime was now blubbering somewhere between agony and utopia. That tongue just kept trying to keep the orgasm going even though now it was almost to a point of pain as Sentinel withered his hips back and forth unknowingly.
Noticing how Sentinel was almost convulsing over the elongated orgasm, Soundwave suddenly waved at the hungry Prime and stated, “Optimus Prime: Acceptable foreplay. Move on to the next section of interfacing.”
Titling his head out of the warm crook that was Sentinel’s thighs, drool and valve juices dripping down his chin, the zombie-like mech nodded and stood. Then, looking over his partner and how Sentinel was slumped, dripping fluids, he asked, “Master, can I bind his legs up to enter easily? He will not be able to support his own weight.”
Sentinel, struggling to gain some of his senses though he knew the program for balance needed to be reset (time he didn’t have), cried out, “Optimus! Don’t do this! Remember the Autobot code! I helped you memorize it with Elita in the academy. Stop!”
His words must have fallen on deaf audios because, suddenly, Sentinel found his legs locked in the chains that had been Optimus’, the pulley system suddenly being tugged and shifting his legs up.
Feeling like a revealed femme, Sentinel immediately closed his thighs when he noticed that Soundwave was staring at his dripping valve. Though, he didn’t get to keep them closed long when suddenly Optimus was in front of him, hands siding between his legs and slowly prying them open.
Soundwave came up behind his zombie to stare some more.
Sentinel actually felt like crying at this point, even more so when Soundwave asked, “Inquiry: why is his valve smaller than yours?”
Optimus didn’t even hesitate as he reached forward and pressed a forefinger in causing Sentinel to cringe as that metallic finger press against his inner seal. Nodding at this, his optics brightening probably at the prospect, Optimus answered, “He has never been entered and his valve has not been stretched before. He even has a seal. All mechs and femmes have them for their valve to keep it clean and protected until they become sexually active. It hurts to break it.”
Reaching forward, Soundwave jabbed a finger in as well, making Sentinel arch as the seal tugged, threatening to start ripping open. Only feeling around for a moment, the Con pulled his finger out and stared at the fluid for a moment before he stated, “Proceed.”
Nodding, the mind-controlled Optimus took a few steps between those spread legs, Sentinel twitching back when Optimus grabbed his aft. The firetruck stared at him with dull optics for a moment and Sentinel prayed the other mech was snapping out of it, only to have his faint dreams crushed as Optimus pressed against him and started to rub against the wet port.
He was getting his spike hard, arousing it.
Sentinel choked in reaction, his EM field rippling in fear. “Don’t do this!”
Optimus just continued to rub, his spike getting harder and harder as it rubbed against the wetness between those thighs. Then, a few short moments later, he finally stopped and looked at his Master, murmuring, “I will now guide my hard spike in and break the seal.”
Despite being disoriented, Sentinel tried to kick out even though his legs were chained up, growling, “Don’t you dare!”
Optimus merely spread those blue thighs again, not detoured in the slightest, and started to guide in his tool, pressing the head in as he slowly started to groan at the other Prime’s wetness. Sentinel gave on more tug on his chains before he offlined his optics and bit his lip, wanting to keep a little of his pride. He would not cry out like a little virgin. He would not cry out like so many of the femmes he had taken in his academy years.
He merely whimpered and arched … when Prime’s member pressed against his seal, the red and blue Prime stalling for a moment. And then, as if finally realizing something, the mind-controlled mech almost lovingly petted Sentinel’s thigh, slowly moving that warm hand to Sentinel’s lower back. Now, acting as a kind lover, Optimus leaned forward and captured Sentinel’s lips in a kiss and he slowly leaned into the valve... breaking the seal.
Sentinel had tried not to cry out, he truly did. He didn’t know if he should be glad that some of Prime’s bedding instincts were bleeding through the device in his helm or not, because the kiss did smother his cry yet at the same time … it made the action feel far more intimate. It was as if Optimus was trying to comfort him as a first timer and that just made the blue mech feel sick because it made the act far more real. Optimus was making love to him not only taking sex from him.
Not that he got to dwell on if Optimus was really conscious for this all or not, because the red and blue Prime pushed farther in causing Sentinel to arch and nearly break Optimus’ heated kiss, that red and grey spike slowly pushing in deeper and deeper, stretching him farther and farther apart … and it hurt! It fraggen hurt! The popping was less painful then the stretching. He was sure he was ripping though he knew that he would not. He had broken a few femmes’ seals in his time and knew a mech of his size could take someone of Optimus’ size as long as he was lubed… and the other Prime had done a fair job of that.
But had it hurt for the femmes like it was fraggen hurting for him now? Especially now that Optimus was seated fully inside him and just sitting there, still, his vents hissing as he stuck his tongue deep inside Sentinel’s mouth again. Simultaneously, the hand that wasn’t holding his thigh up was even rubbing Sentinel’s lower back. Optimus’ optics were even dimming with pleasure, more soft touches following after.
Sentinel, trying to forget the femmes he had taken much like Optimus was taking him now, offlined his optics and prayed for his old friend to stop. Or to at least stop touching him so softly and to stop kissing him because … he just couldn’t take that. At least a cold fuck would have been less degrading but it seemed that even though Soundwave had the other’s mind … it didn’t change how Optimus interfaced.
A part of Sentinel’s mind mocked him for being raped in such a way.
Suddenly, interrupting the victim’s thoughts, a low groan escaped Optimus and he pulled up on Sentinel’s thigh. He then shifted, pulling out slowly centimeter by centimeter until he was barely a few centimeters still inside… only to press back into Sentinel’s warmth.
Despite the slowness of his re-penetration and the soft kisses that were littering from Sentinel’s mouth and down to his neck cable, every pain receptor let the blue Prime know its distaste in this situation. Sentinel could only throw his head back in a silent scream as Optimus got all the way back inside again. Optimus merely groaned as their thighs met and kissed Sentinel’s chin before he pulled out halfway and slowly pushed back in as carefully as possible. This slow love making repeated itself a dozen times, and though Sentinel’s legs started to shake, it wasn’t hurting as bad as when Optimus had started.
Optimus was trying to make it good for him and that… that was just making him ill. He was getting raped! His body shouldn’t be adapting to it!
Wailing in mental agony as Optimus pushed all the way back in, stretching the tight little port as the truck-former sucked on a neck cable, Sentinel blubbered, “Stop! Please Optimus, you are s-supposed to be too good for this l-like always! Uh! Stop! Y-your st-stretching me too much!”
Optimus stalled for a moment as he raised his helm to meet Sentinel’s gaze and for a nano-klick the blue mech was sure his ex-friend had heard him and was about to pull out. Instead, Optimus merely stalled and stared down at Sentinel as if confused, as if asking ‘isn’t this good for you?' Then, releasing the other Prime’s lower back, he brought that hand toward their equipment.
Relief overcoming Sentinel slightly, the blue Prime thinking that Optimus was going to use that hand to slowly guide his spike out. Instead, a thumbed digit came forward and started to rub on the nub of Sentinel’s housed spike. Since his valve was currently full, his spike was unlikely to pop up because his interfacing programs were laboring to intake new information from the valve, but rubbing the tip of a spike was a good way to arouse a lover and get them to come if they weren’t being completely pleasured or were in pain. A trick Sentinel had used on many popping femmes himself.
Smiling softly, his mind likely unaware that this was rape, Optimus started rubbing the equivalent of a clit making Sentinel arch again … gasping. It was feeling really good at this point, like when Optimus had been bobbing between his legs. Quickly shaking his head, hating how when his hips swung into that metallic spike that it actually felt really good, Sentinel tried to recall the pain of his popping to chase away any warrant for pleasure.
Arching again as Optimus shifted inside of him, the hand that had been on Sentinel’s leg moving upward as the other hand remanded on the revealed head of the blue mech’s shafted spike, Optimus leaned forward and started picking up the pace. Moaning, finally able to create some friction because Sentinel was now squeaking with each penetration, Optimus buried his helm in the crook of Sentinel’s neck kissing and moaning and venting as his spike's pace picked up along with the rapid rubbing of the thumb between the two of their thighs.
Sentinel arched, the edge of the cliff crumbling and he was about to fall over the edge, his hips trying to get away yet wanting to be closer despite how much it disgusted him at the thought Optimus was about to bring forth an orgasm. Throwing his head back, another tear falling down his cheek, Sentinel choked, “Please stop! Please… I-I can’t … You are going to make me come! Pp-please don’t filthy me in this way!”
Optimus merely moaned, moving faster inside him as he started kissing the side of Sentinel’s cheek and chin again, whispering, “It’s okay. It’s okay … to come. I want you to come.”
Sentinel whimpered in his throat, legs shaking. He didn’t know what else to do. The tingling was happening again. It was pulling at his inner chamber and was holding him on edge. It was so frustrating and horrific and it was starting to feel so excellent though a part of him was horrified by the prospect. Not knowing what else to do, Sentinel threw his head back in a wail of emotional agony as he gave in and started to ride that spike for all he was worth, pressing his hips into the other mech as he hoped to just come and be done with it. He even went so far to arch his neck so Optimus could smother him in kisses and licks.
Optimus took that as an invitation and grabbed Sentinel’s hips and the pace now pounding, slamming so hard into that valve that it felt like enlightenment to both of them. Sentinel could only whimper in response though, trying to shift and get more spike inside of him … the pain enlaced pleasure driving him further and further to the edge.
Soon, there was nothing but the sounds of pounding metal and the smacking of fluids filling the room, Sentinel half crying out with each slam into him which only drove Optimus into a frenzy as he littered more kisses on the other mech, squeezing Sentinel’s aft as droplets of lube fell onto the floor. Sentinel, finding himself getting even more aroused by the grunts Optimus was making with each slam into his aching port, suddenly felt the walls inside his valve still … pushing him over the edge… and then he came, hard. He arched up once more against his chains, the cock pressing into him deeper than ever, a screech so loud that Soundwave winced.
Finally, it was over. Sentinel was elated for a few nano-kilcks before he collapsed into his chains and Optimus’ hands, Optimus Prime’s spike expanding as it blew its load of nanites inside of the blue mech, filling him full of hot cum.
Sentinel couldn’t help but arch slightly against his chains as his insides became hot and sloppy with the fluids filling him up. Optimus could only pant as he continued to spill his load. Then, still too full of Optimus’ spike to react, Sentinel watched in disgust as the visored mech got nearer to watch with interest as Optimus’ member expanded slightly and released the last of its load into the deflowered valve, minuscule amounts of nanites dripping down to the floor with energon and valve lube.
Nodding, standing up to stare at a gasping, whimpering Sentinel, Soundwave turned his attention to the dull opticed mech, requesting, “Show me more.”
…
“Uhh, uhhh … Ahhhhhh!” cried Sentinel as he finally came, the spike still pressing into him as his once-friend rode him doggy style, chains braced to the floor. Optimus cried out a moment later, the valve swallowing as he came, the mech’s member as far as it could get inside another splatter of warmth spilled inside of the blue Prime… for the fourth time that night.
Optimus had told Soundwave there were apparently thirty-six positions Optimus admitted to knowing and the sick fucker probably wanted to see them all.
“Next position: On top of him. I wish to see a breeding or spark rubbing as you called it. He has enough nanites in him: Correct?” said the monotone voice, almost excited as he watched the cum drip to the floor below.
Slowly nodding, Optimus quickly rolled Sentinel over onto his back, chains shaking as they were repositioned, loose but still constricting. Sentinel only shook his head in disbelief. It even took a moment for the blue mech to truly comprehend what was about to happen before he could react. Yes, his valve hurt, his pride ached, he was overflowing with Optimus’ nanites, but up to this point, it had seemed surreal. True, the likelihood of being impregnated was only three or five percent for a new couple as the chances increased with each unprotected bonding, but sharing one’s spark… made it real.
A bond, no matter how weak, would form.
He could have told himself it wasn’t that big of a deal, he could pretend it wasn’t there, but every partner one shared their spark with created a bond that would prickle from time to time as a reminder that the sparks had once been one. That bond, in effect, would always remind him that tonight … had happened.
He would always be soiled.
Finally snapping out of the stupor the helm wound and Optimus’ surprisingly thoughtful lovemaking had created for being raped, Sentinel screamed and kicked out like a femme being gang raped by half a dozen mechs in an alley. Sentinel didn’t care if he was sluggish and sore and embarrassed and that he wasn't minding his training as a soldier to remain calm! He was not letting this happen!
With a vengeance, his repair systems probably working on his systems despite Optimus’ rigorous workout, Sentinel started kicking out his loosely chained legs as he started roaring.
Optimus merely murmured like a half-drunk fool that didn’t really understand what was going on, “Shh, shh. I will make it feel good. It will be so good. You’ll come and our sparks will…”
Sentinel just cried out, EM field flaring, “No! No! Don’t sully me this way! I was your friend! I was your friend until you let Elita die! Please, b-because of that. Stop! Stop!”
Soundwave growled, his sensitive sound receptors not liking the sudden noise, yet the blue Prime was now crying out like when Optimus first started taking him. Rising to his feet, just wanting to see where this went, maybe only breaking down Optimus for parts if the blue mech was bountiful with a sparkling and later trying this interfacing as well, Soundwave walked toward the struggling pair.
Not even missing a beat, Soundwave was suddenly in Sentinel’s field of vision, hand spread wide and then there was a squeal from a small speaker in his palm. A sonic weapon and then everything blurred. Sparks of light seeming to freeze in time and space, Optimus’ words dulled though he knew on some level that Optimus was now back inside of him from the grunts and the whines, kisses on his helm and chin. He couldn’t feel that spike pounding into him or how long he had been disoriented until feeling started to return to his limbs, his valve twitching in pleasure.
It wasn’t until Optimus’ voice whispered, husky and struggling like he was just struggling to keep his voice even, “Master, I will now open his chest. I’m getting close and so is Sentinel’s valve. I will continue pleasuring the two if us until we both start orgasming and then I will press our spark glasses together, joining our beings for a short time. The building charge may split off and create a sparklet from our two combined beings. If there is transfluid and the sparklet survives the plunge into the carrying chamber a sparkling may be created from the union.”
Reaching a hand up, chains clunking loosely, Sentinel tried to move his mouth and beg for Optimus not to do this. Pit, maybe he would even threaten him with a court-martial or anything to stop this, but his systems were still regaining themselves and all he could do was mumble incoherently as Optimus found the release latch for his chassis. The room was quickly bathed in light, soft blue with shivering textures of electric navy-blue from time to time as his spark shifted in its casing. Soundwave merely watched envious for a moment, knowing that soon he would have to get a shard of the Allspark to have one as well before he tilted his head to Optimus.
Optimus, not needing to be asked, opened his spark chamber as well.
Gold.
Optimus had a golden spark. A color that promised great things. No wonder Ultra Magnus had given him a second chance. No wonder… everyone had loved him, unlike how no one seemed loved Sentinel. They all praised Optimus, except for Elita-1. She had only seen him, but Optimus had taken that away.
He wouldn’t even let Sentinel die with her.
Sobbing in his throat, the edge was coming, Optimus started leaning down ready to share his being. That spike slammed a few more times, soft nothings in his audio, and finally, Sentinel came. His valve rippled so hard he felt like it was devouring Optimus’ spike and Optimus choked as he came without warning as well. Sentinel, knowing not what else to do, threw his loosely bound arms around Optimus’ neck as he buried his head in the crevasse there. Optimus didn’t waste a moment pressing their sparks together as they fell downward in overcoming pleasure. The spark rubbing threw light everywhere, lighting up the dark torture room and in effect caused both of their orgasms to keep coming. Soon, sparks flew and there was this elation as two souls started to join, flowing into each other likely ghostly tendrils. The jolt, a minor bond starting to be created, bloomed in their chests as the sparks started spinning against each other faster and faster trying to match wavelengths until they were suddenly pulled apart. The jolt caused Optimus’ spike to stall its pounding and come again, hot cum splashing inside of Sentinel once more which caused the blue mech to arch and cry into Optimus’ audio, his valve rippling as it devoured the other Prime’s fluids.
For a moment, the smell of Optimus in his olfactory, Sentinel almost felt like this was an act of love. That they were sharing their sparks in an act of companionship. Optimus’ spark was so warm, kind and forgiving. It was also sympathetic as if it knew it had no control over the situation, pressing against Sentinel’s shame and fear as it tried to offer nothing but love and understanding. And for a moment… the afterglow as wonderful and he pulled Optimus as close as he could in appeasement.
He even felt Optimus kiss his helm… and then reality came crashing back down, Optimus arching up and grabbing his own helm in pain. Sparks were jumping all over the device that was attached to his helm. It was shorting out from the extra electricity from their joining! And then the firetruck’s optics went offline, his chassis closing of its own accord before he collapsed on top of Sentinel with a dull thud… spike going limp inside him.
Soundwave actually jumped back in surprise, his posture guarded. And for a moment as there was nothing but silence, the only sound Optimus’ system winding down while Sentinel’s engine hiccuping.
Slowly, the Con stood up straight and came forward, leaning down to poke Optimus. After he didn't get a reaction, Soundwave murmured, “Spark sharing overloaded mind control device? Hypothesis probable.”
Shaking Optimus once more for a reaction, the blue Con huffed and then reached under Optimus’ armpits and lifted him up, pulling him out and off of Sentinel. With a grunt he turned Optimus on his back and then knelt down, playing with the device attached to the repair-bot’s helm.
Sentinel merely lay there on the floor, chains loosely bound because of Optimus’ last position, his mind was vaguely aware he was covered in fluids and his equipment hurt and … and Optimus’ mind control device had shorted out because of the spark overload. Soundwave was currently leaning over the other Prime trying to fix it … Sentinel had been forgotten.
Unfortunately for the Con, his back was now turned to Sentinel and the charge had reset some of the blue mech's systems. He was not dumb enough to waste a chance like this.
Not wasting another moment, hate and fear pulsing through his EM field, Sentinel sat up and grabbed his loose restraints throwing them around the Con’s neck.
The earth model barked in surprise as they both fell backward and with quick reflexes the musician elbowed Sentinel in the chassis, aiming for the open spark chamber. He barely missed.
Grunting in surprise, struggling with slow systems, Sentinel was able to get his chassis closed, but the distraction had done it's job and suddenly Soundwave was straddling the slightly larger Prime. His hands were now reaching forward and around Sentinel’s neck, cutting off the tubing that brought energon to his helm.
Sentinel sputtered, hands reaching towards those thick blue fingers around his throat, but Soundwave’s grip was too sure and he couldn’t rely on his training to slam his palm into the other’s face because the chains were just too short. He wouldn’t even be able to try and poke out the other mech's visor!
He was going to deactivate and if Optimus got out of here, everyone would know that he died weak and pathetic like a raped femme. He would be dishonored in deactivation. Would he even get an Elite Gaurd funeral?
No, that was too much to bear. He was already defiled. He would not die remembered only for that and not any great feats. He hadn’t even been in a great battle yet while Optimus apparently had.
Rage suddenly bubbling forth, optics searching for anything, everything, he saw his chance. A stone. A simple stone.
He didn’t waste a moment grabbing it and slamming it into the musician's neck. The other mech grunted, rolling off … and after that, Sentinel didn’t recall his training, his honor and the rules of an Elite Guard. He just saw someone else slamming that stone repeatedly into the blue Con’s helm. And they couldn’t stop.
They just kept smashing and smashing and smashing, fluids slowly covering their hands like a grisly horror movie.
They…
No, no. This was him again. H-he couldn’t stop himself from pounding Soundwave's helm into the cement even when the stone had crumbled into rubble. Even when the Con’s limbs stopped twitching and there was oil splattering everywhere with each impact of the now broken-open helm. Sentinel couldn't stop. Only once he heard a moan from Optimus echo over the room did Sentinel stall, his optics going wide.
The other Prime was snapping out of it and soon he would be able to figure out what happened if he didn’t remember everything already! Both of their latches were open.
Swallowing a whimper, Sentinel struggled to his feet, collapsing once before half crawling over to the other mech. Once there, he reached into a leg compartment and grabbed a rag that was meant of cleaning his weapons. He wiped Optimus' spike off, pressing it down into its casing as his optics struggled to find both of their cod pieces.
Luckily, neither one was very far and he was quickly pressing Optimus’ latch down onto the groggy Prime. A heavy click filled the room just as the truck-former raised an arm to rub his head.
Rushing to hide the evidence, Sentinel turned his back for a moment to wipe his thighs, more worried about the nanites then the fact that his hands were covered in oil. Then, stuffing the rag in his port, wincing as it stung, he clicked his own codpiece shut just as the repair-bot sat up.
“Uhhh, what happened?" groaned Optimus. "My head… We-we were chained up … and how did we both get on the floor?”
Sentinel turned his head in a panic and almost wept in relief. He was so glad that his hunch was right that the zombie-state wouldn’t recall raping his ex-best friend since Optimus had no control over his own actions. It had been a wild guess that Optimus wouldn’t remember, but even if the other Prime did remember… Well, he would reply it was madness! Soundwave was just messing with his mind.
Nodding to himself, Sentinel looked at his hands as the other Prime slowly got to his feet, glad that the oil was covering up the stains of their joining. He was so shell shocked that he barely even noticed that Optimus was standing over Soundwave’s corpse, a hand over his mouth and his optics full of horror. Optimus' voice was barely a whisper, “W-what happen here?”
Struggling to get to his own feet, though he was sure he would collapse, Sentinel stood up as proudly as he could, “Nothing, I took care of him … let’s just get out of here.”
