Shockwave had noticed his lab in the Sea of Rust was getting more and more traffic, especially by Megatron's troops. He was of Decepticon allegiance, but he liked his isolation from time to time. One noticeable visiting pair was Dreadwing and Skyquake, Megatron's field sergeants, or the "Terror Trouble Twins" as Motormaster once put it. They ruled the skies over some of Megatron's taken territory.

Now, Shockwave was lenient, but they were getting on his nerves, especially the one called Skyquake. The less reserved green twin was always ignoring what Shockwave said, instead staring down him with an unknown expression Shockwave wasn't familiar with and didn't want to be. Dreadwing at least had a shred of respect when he told them to buzz off kindly. Skyquake, however, didn't really seem interested in obeying that wish.

While Dreadwing left at some point, Skyquake somehow got into his lab which wouldn't have been a complete annoyance had the Seeker not started talking...

"Quite a comfy, little retreat you have. I'm jealous," the deep baritone rumbled.

Shockwave tried to be polite but firm while looking over his recent finds on some prisoners he had in his tower. "Yes, it is. Is there anything else you require to report to Lord Megatron?"

Skyquake pushed off the wall he had been leaning on and walked towards the shorter mech sneering, "Not so much our lord and master. I'm just more curious why our dear scientist is so desperate to get rid of us."

"I don't know what you are insinuating. I have no problem with you-"

"But I have with you," Skyquake suddenly declared when he stepped up behind Shockwave. The scientist turned immediately with a hostile pose in defense. Skyquake was unbothered. "You think you are so superior to us that you can sit in your castle all day and we are supposed to bow to your ideology, do your dirty job and you treat us like scrap? You know, I don't like bots like you. Except for Megatron, all you commanders are useful for is looking pretty and putting your chassis to good work to appease the highest power like some blowhard harem."

Shockwave grew furious at the childish, absurd accusation but gave a sarcastic reply, "My work is what is currently keeping the Autobots at bay from behind the lines of the battlefield. Maybe it isn't as important as you think, but I probably saved your aft more than you know just by standing still and 'looking pretty.'"

Shockwave was suddenly pushed back and pinned against the slated console attached to a giant vat of bubbling yellow CNA hosting the embryo of a beast he was trying to clone. Skyquake dwarfed him with a snarl. He was sitting on his controls hoping his locked settings didn't risk being compromised by him. Skyquake's servos slammed beside both sides of his waist as he was forced to lean back.

"Yeah, you sound like you have," the Seeker growled humorously. "How many spikes were in you while I was being shot at in Technahar getting your precious data from Optimus Prime who I was instructed to also assassinate? What valves did you sink yourself into like a leashed pet when I was the one making sure no Autobot could lay a digit on your charming tower during their planned invasion two months ago? You sit up here playing with yourself while we slave away...so, I think I'm owed a little payment for my services to you."

Shockwave was taken aback by the accusations. He never had time for anybody, and his work was most important. But he saw Skyquake's terrible smirk making him realize the mech was dead serious and crawled backwards farther up the console. Skyquake caught his legs and forced himself between them with his glossa snaking across the side of Shockwave's helm. His optic dimmed in distress until the Seeker abruptly started grinding against him.

He was never one to whimper, but the motions were sharp. Skyquake's body rubbed against his as he was forced to place his legs over the latter's hips. The tension hurt on his interface but was sending a few signals that made his chassis heat up. He refused to give Skyquake the pleasure of his voice. He didn't deserve it.

"You like that, don't you?" Skyquake grinned, his motions never ceasing as he released his spike. "Think you can scream for me beneath that cold exterior of yours?"

Shockwave felt the spike rubbing against him trying to coax him to open. The green mech's servo paw at his interface after a second determined to frag him. He was suddenly exposed by the betrayal of his system when he could imagine the mech wouldn't be forgiving. As soon as he presented his valve, Skyquake penetrated him with a hiss.

The motions were rough. Skyquake assumed he was already a used toy for others to be able to take him. Shockwave refused to say a word as his chassis was forced to meet sharp thrusts that sent his processor haywire. His claws could only rake across Skyquake's shoulders for some comfort. The hardest thrusts came when he turned his head to the side to see his reflection. Skyquake didn't like the attention off him, but it was Shockwave's only comfort.

Shockwave saw himself being pounded into and a part of him grew aroused by this, not from Skyquake himself. His valve was becoming sore from Skyquake's rut, but the stinging enhanced the newfound pleasure he was starting to collect. Maybe he wasn't a toy to others as Skyquake got horribly wrong, but the mirrored image of his taking spoke a different language.

Abruptly, Skyquake panted as he unloaded inside Shockwave before suddenly dispersing his valve and letting the poor scientist drop onto his aft on the ground. Shockwave still remained silent but was displeased. Skyquake smiled down as his own fluids and Shockwave's leaked out of the valve he tainted.

"You're a miserable bastard, Shockwave," the Seeker said above him, "but perhaps you are more useful like this after all. When I get back from Kaon, I expect you to be waiting for me like a good mech and if you tell anyone, I'll rip you in half."

Shockwave refused to make eye contact as Skyquake left him to suffer mid-charge. He sat there with the faintest streaks of Energon leaking with the transfluid and lubricant. He pressed his helm on the back of the console breathing hard until he remembered the reflection of him and Skyquake. He needed release or else the charge would burn up in him.

Crawling to where his reflection was most prominent near a flight of stairs, he rested with his back against them ignoring the trail of fluids he left on his journey and opened his legs again so the reflection could show off the view of his mistreated valve. It looked like a horror show down there, and Shockwave was oblivious of that as he was used to doing far worse things in his lab that looked infinitely more horrifying.

After staring at the reflection of his exposed valve, he reached down and dragged his claws over the puffy petals with a hiss. The exterior node was highly sensitive and caused him to flinch when he teased it. He started massaging his valve, touching the mixed fluids and using them to slicken himself to ease the pain. Skyquake's transfluid was most prominent.

He gathered as much of Skyquake as he could and stuffed it back inside him along with his digits in a quickened pace. His reflection mirrored his display and only encouraged him to work harder. No, he wasn't used to this. Years in isolation had him not seek a purpose to, but he found utmost pleasure in seeing himself more than being fragged by an arrogant Seeker with a big spike.

Lubricant was starting to compete with Skyquake's transfluid in a battle for the rights to his valve. Shockwave lifted his right leg and reached around to re-enter himself from a different angle, his three digits shoving inside hard enough to accidentally claw his inner walls. He didn't care as he clung to the stair rails and nuzzled them with his core rising to reach dangerous levels. His reflection didn't hide anything.

Finally, he let out moans he had been keeping inside. He refused to talk to Skyquake but in his privacy rolling back against his deep fingers and seeing himself acting like a pleasure bot, he saw no reason to hold back anymore. There was a puddle of three different fluids beneath him when he overloaded. He drew out the sensation with several hard thrusts until he collapsed back against the railing. His reflection looked like a mess. He was partially ashamed of himself for sinking so low.

Skyquake didn't understand. He wasn't supposed to be like this. His tower was not a brothel. But would he be able to stop the mech from coming back? Did he even want to? He had never slept with anyone previously since his Council days, but Skyquake was thoroughly convinced he would fuck any Decepticon that breathed. A lousy mistake...

Sure enough not long after, Skyquake made good on that threat. Shockwave was in his tower peacefully when the mech came by with his brother. Did Dreadwing even know what his twin had done? Dreadwing was always kind and relayed what he needed to, did what he was ordered to, but Skyquake was giving Shockwave a smirk with the same ferocity as before. When Dreadwing left, Shockwave instinctively backed away.

"Shockwave," Skyquake sang, "I believe I need a certain favor."

The scientist's valve automatically lubricated this time. He programmed himself to do that now just in case. He led Skyquake to a room with a berth and several mirrors he set up. Skyquake didn't care for their purpose, but Shockwave did. As he was once again taken repeatedly, he saw his reflection and found tolerance. Only after he was left to stew in the aftermath like a marked bitch did he finish the job himself.

Digits moved in rapid motions and keeping Skyquake's fluids inside him looked so well in the mirror he was in front of. His legs were above him on the wall, his aft against the mirror and his valve was aligned and touching its own reflection. He panted through strained vents watching his swollen valve being abused by his own accord. When he came, his valve gushed out Skyquake's transfluid and his lubricant onto the mirror. It came sliding back down onto him.

His reflection showed him as he truly was, something Skyquake could use but never claim. A whore for himself.

AN: Probably the most realistic version of Shockwave because I'm pretty sure if he was sexually active, he would be very narcissistic and some narcissists only get off to themselves in sexual situations, not by anyone else regardless of activity. Narcissism also can be associated with mirrors and self-belief of assigned labels. If I had to say what Shockwave is in a real sexual situation from his character alone, this would be the closest interpretation.
