Chapter Text
Soundwave’s whole frame went rigid as Shockwave’s deep voice washed over him, tearing through the constant noise of his own cooling fans. He could feel sharp fingertips tracing the panel covering his interface equipment. They skimmed over sensitive circuits and then tugged on a few cables, almost experimentally. It was not yet a proper caress, but the touch could no longer be called unintentional, not by a long shot.
After everything he had been through this cycle, Soundwave’s processor was slow to react. His automatic defense systems refused to register the servo on his heated plating as a threat. Far from it, his frame seemed to consider the touch very welcome. He could feel his spark pounding in his chest as his hips ached to push into the teasing strokes.
While Soundwave was still struggling to catch up with reality, Shockwave’s servo got bolder, more determined in its exploration. Claw tips prodded every single nerve sensor in the vicinity of his interface equipment, methodically one by one. Soundwave managed to remain unmoving, but only barely. His mind was racing as he struggled to understand.
What was it that Shockwave wanted from him? Was he expecting some sort of payment for repairing him? Or was it just idle curiosity? Did Shockwave just wish to see how he would react? Or did the mech get some sadistic pleasure from tormenting him further? Before he could come to a conclusion, however, the servo withdrew completely.
A frustrated huff of hot air escaped Soundwave’s vents at the sudden loss of contact, regardless of his efforts to hold it back. He onlined his optical feed just in time to see Shockwave freezing in mid-motion, still half bent over his “patient”. His servo lingered in the empty air between them, as if he could not decide whether to touch him again or to pull it back fully. The little winglets on his back twitched.
“I have finished your repairs. You can leave now.”
Shockwave pulled back a little, but kept his brightly glowing optic on Soundwave, who did not make a move to get up. To say he was confused by Shockwave’s behavior would be an understatement. It was extremely illogical for the mech to release him now, without making any demands in turn.
A few kliks passed with both of them staring at each other, trying to gauge each other’s intentions. Then Shockwave appeared to tear himself away from whatever thoughts he was entertaining, shaking his head almost imperceptibly. Soundwave caught the little movement and he started to wonder what kind of effect their current situation had on the usually unflappable mech. More importantly, he wondered how he could use that to his own advantage.
“I said you can go,” Shockwave repeated unnecessarily, dismissing him with a nod towards the exit. He did not wait for Soundwave to move and immediately opened a concealed panel below his chest, pulling out a thin data cable.
“I trust your report to Megatron will be … favorable.”
His voice was still flat, but it seemed to hesitate in strange places. Far more telling was Shockwave’s EM field. He utterly failed at hiding the hunger, the want, in it. He probably had no idea how obvious all of that was to a mech like Soundwave. The only thing the communications specialist was still trying to decipher was the exact nature of Shockwave’s desires.
Noticing that Soundwave had still not moved, Shockwave spoke again, this time with something very close to impatience in his voice.
“I suggest you dispel the heat in your frame before you go back to Megatron like that.”
His tone suggested that he was not likely to give Soundwave any assistance with that. He almost sounded as if he wanted him gone as soon as possible, Soundwave thought with dawning realization. Doubtlessly, Shockwave was already busy imagining the experiments he could do with the data he had gained from examining him. Soundwave did not even want to know what the scientist would do with the data. But he did intend to do something about the charge wreaking havoc through his systems before he left.
The chance presented itself immediately, when Shockwave gave in to his curiosity and plugged himself into the medical console to download said data. It was positively careless of him to get so carried away, Soundwave thought. Very unusual for such a careful and patient mech to forget that his “test subject” was still connected to the terminal as well.
But it was also a chance for Soundwave to get what he had desired for a long time. When it came down to it, the prospect of getting into Shockwave’s mind was a hundred times more arousing to him than a mere touch could ever be. Maybe there was a small possibility for that as well, because now that Soundwave had gotten a first taste of it, he wanted that too.
He wanted the graceful fingers to touch him in a less controlled and clinical way. He wanted to see how far Shockwave’s interest in him really went. Beneath the scientist’s impenetrable exterior he had caught a glimpse of emotion… and he wanted to see more of that. He wanted to see Shockwave’s self-control crumble beneath his own skilled ministrations.
To have desires such as these was rather unexpected for Soundwave, who had always craved the exchange of data more than any other form of conventional interfacing. But he was not about to pass up this chance. Who knew, maybe Shockwave’s future cooperation could be secured by making this pleasurable for him as well. Before the occurrences of the last cycle, Soundwave would have never even thought about the possibility of seducing Shockwave (it still sounded absurd to him), but now…
Soundwave made his decision in a split second. His arm shot out so fast that Shockwave had no chance to escape. Deceptively slender fingers curled around one of the antennae on the cyclop’s head and yanked, pulling him half onto the berth before he could even think about struggling. Shockwave was not the only one who knew a few highly sensitive places on the other’s frame.
Soundwave did not loosen his grip even when Shockwave’s prominent chest clashed against his own plating with an audible clang. It took only 2.45 astroseconds and he had found his way through the external console into Shockwave’s processor, where he hacked the first two firewalls with the speed of a single thought.
“Soundwave! What…!?”
Before he could finish the sentence, Soundwave had broken through several further layers of defense. One by one he circumvented firewalls that were erected too hastily to keep him out. He found what he had been looking for with ease. Unlike other mechs, he did not need a primary interface cable for what he had in mind.
With profound relief, and a surge of triumph that was once again rather unusual for him, Soundwave manually initiated Shockwave’s interface protocols. He was startled to find that they had not been used in eons, or perhaps much longer. As he had anticipated, now it was Shockwave’s turn to go utterly still on top of him. But he did not relax his crushing grip on the sensitive antenna, just to be on the safe side.
Almost instantly, Soundwave could feel the heat growing in the massive engine pressed against him. He was careful not to cause Shockwave any pain, but creating a proper link in such a way was difficult. He might have pinched a few sensors in his tight grip, but he rather thought that Shockwave deserved a little payback for his less than gentle examination earlier.
The whole experience was different from using interfacing cables, but surprisingly, it turned out to be extremely pleasurable for both of them. It was as if they fit each other in a way that defied statistical probability.
The antenna in his grasp trembled and Soundwave shivered as well, their frames in perfect synchrony without even trying. The sudden feeling of connectedness between their minds was new to Soundwave. He could not remember ever feeling such passion, not like this. It was a strangely familiar pleasure, even if he was sure he had never experienced anything like it.
Soundwave’s slender body pressed up against the much heavier frame, finally free to writhe and move as much as he wanted. It was liberating and Soundwave softened his grip a little. He reduced the pressure on dented sensor arrays and began stroking up and down, almost an apology for his earlier roughness. His other servo came up and explored the massive canon arm, his fingers tracing along the edges of the angular chest.
Shockwave had been utterly stunned at first, but now he slowly seemed to come back to himself. His optic flickered erratically as he briefly attempted to escape Soundwave’s manipulative touch. Only now he seemed to remember that he was supposed to be wary of his fellow Decepticon. But Soundwave had no intention of letting him go. He replayed Shockwave’s earlier words, loud and clear:
‘I suggest you lie still.’
Shockwave went obediently and satisfyingly limp as Soundwave started to feed him with data through their connection: ideas, thoughts and carefully strewn hints of secrets. Between the bursts of data there were images of Soundwave’s lithe frame arching up into Shockwave’s touch, pictures of all the things Soundwave would allow him to do. In as much detail as possible, Soundwave let the other feel what he had been feeling earlier, showed him his willingness to be touched and claimed.
Shockwave’s cooling vents switched on and their powerful thrumming vibrated through the both of them. His mind responded eagerly towards Soundwave’s gentle touches and he took greedily from the stream of data offered to him. At one point he tried to vocalize something that could have been Soundwave’s name, but static distortion made it impossible to tell.
Soundwave was pleasantly surprised at how easily Shockwave’s control was slipping, how strongly he was reacting to this kind of seduction. All thoughts of resisting him were long forgotten; Soundwave could feel it in his shifting EM field. It openly radiated curiosity, pure and unbelievably deep desire for knowledge and for new information, and an obsession with things that were horrifying and fascinating at the same time.
Trapped between their bodies, Shockwave’s servo started to move as in Soundwave’s fantasy, which was now shared between them. He drew sharp claws along a newly welded scar on Soundwave’s hips, scratching over sensitive metal, and Soundwave could no longer hold himself back. He finally opened up his own EM field and allowed his desire to bleed out and answer Shockwave’s hunger with his own.
“What are you…”
Shockwave broke off and droned tonelessly in approval. His faculty of speech was completely gone by the time Soundwave decided to increase his efforts. The communications specialist kept pushing images through their link, of himself being restrained by the berth’s shackles (and the moan Shockwave could not quite suppress at that told him he had guessed right about the mech’s proclivities).
Soundwave no longer attempted to slow the other Decepticon down. Shockwave’s hunger was contagious and was impossible to resist. Plus, the knowledge that Shockwave was this curious about him intrigued Soundwave in turn and fuelled his own spark-felt desire for information.
Scraping together the last remains of his considerable patience, Soundwave kept teasing, aiming to coax the other into opening up his mind and to share more of himself. He added a few other experiences that he thought would appeal to Shockwave, such as memories of a gladiator’s heavy frame pressing him down. That got a very enthusiastic reaction, too. Interesting. So that was something else they had in common.
Sooner than he would have liked, exhaustion pulled at Soundwave and made him shake. He was forced to press closer against heated purple plating to hide it, forced to rest his facial screen against a broad shoulder and reluctantly slow down his pace.
In the end it was Shockwave’s own curiosity that made him take a more active role, not just Soundwave’s fatigue. The scientist was still reluctant to share his thoughts and memories, but he clearly enjoyed the ecstasy he inflicted on Soundwave. He gave a first mental brush through their connection, curious to see his interface partner’s reaction. Soundwave answered with a series of long drawn out pulses of pleasure that seemed to please him well.
When it came to giving pleasure, Shockwave was apparently just as careless and rough as he was with everything else. Even the small amount of data he decided to share was almost too much. So many ideas, experiments, inventions, projects -- it was pushing at the limits of Soundwave’s strained awareness and made him shake uncontrollably. He could feel the overload building in his whole frame, from his pulsing spark to his legs, which had at some point slung tightly around the purple frame of their own accord.
They had been connected for what could only be a few moments. Normally Soundwave enjoyed a longer, slower interface, but it was clear to him that neither of them would last much longer. Relentlessly, Shockwave pushed them towards the edge with all the force of his powerful mind. Clearly he had no experience in prolonging the pleasure of this act, as well as no desire at all to do so. His field flickered a few times before it exploded all around Soundwave.
Unable to resist much longer, Soundwave followed right after him, the fresh energon making his charge sharp and his overload so intense it was almost painful. He did not complain about the weight slumping against him, pressing him flat against the operating table. The warm glow of satisfied desires still drifted through their shared thoughts for a few moments, but Soundwave was quick to pull himself out with steady fingers.
Shockwave groaned. As soon as he had fully regained consciousness, he pushed himself up warily, as if he did not trust Soundwave to not pull another unexpected stunt on him. The next thing he did was check himself for malware, doing a scan of his lab as well. He obviously expected Soundwave to have hacked him or planted some sort of spying device while he had been momentarily distracted.
Soundwave resisted the urge to quote Shockwave’s earlier statement about his continued mistrust being insulting. He highly doubted Shockwave would find the microscopic listening device he had placed under the table. Instead, he rose from the table in one swift, graceful movement, testing his legs with careful steps. His knee joints still felt strangely weak.
After a few meters Soundwave stumbled slightly, easily managing to catch himself. He was genuinely surprised to look down and find the servo, which had been the cause of so many conflicting emotions during the past cycle, touching his arm right under the Decepticon symbol. The contact evoked a pleasant tingling that startled himself as much as it did Shockwave, who appeared rather confused by his own gesture.
His optic continued to switch between Soundwave’s visor and where he was still touching him, but his tone was once again devoid of emotion.
“There seems to be some issues with the energy feedback in your legs. A common complication with this kind of surgery. Your self-repair will take care of it, no doubt.”
Soundwave nodded and turned to leave. Before he had even left the building, Shockwave received a request for an additional check-up in two vorns.
