Requested by Juniper Torohex

His creation was beautiful. He remembered when it first awoke, a loud roar rumbling his laboratory like an earthquake. So perfect, so magnificent words really couldn't describe what he thought truly. Then the most interesting thing happened not long after its introduction to Lord Megatron, it turned into a mech. That was a surprise he hadn't anticipated but technically he saw no downside. The mech who proclaimed himself "Predaking" was even more intimating than his own master. A gorgeous specimen of muscle and might.

Personally, Shockwave was never one to interface or even consider such an activity since there was always work to be done but upon seeing his beast turn into a mech, he had a multitude of mixed feelings that were foreign to him. He wanted to know what that mech could do, if he was a monster in more ways than one. So many questions poured through his processor day and night and he had to know.

He approached Predaking, rubbing the waist of the mech as if he was stroking the underbelly like a good owner would their pet. Predaking purred, seemingly unaware of the intentions of the scientist…or so the latter thought. Shockwave could feel the curvature of the armor made to shape his beast's abdomen, much more defined than most other bots and he wished he could feel further without startling his pet. He paused when he realized how this type of thinking may have been taking things too far. Backing off, the mech pointed his helm down in shame of himself.

The Predacon smiled, "You seem afraid, do I scare you?"

Just to see how the king would react, Shockwave gave a faux scoff, "Hardly, Megatron is the most ruthless and you are my creation. How can I fear you?"

Predaking grimaced angrily at the mention of Megatron but his aggression faded as he peered towards his creator, noticing how the mech had a rather nice body. He would show the Decepticon Leader who was most feared and maybe change the loyalties of his scientist in the process. After all, Shockwave was an underappreciated mech and that was unfortunate for a fool such as Megatron not to praise this intelligent, charming…beautiful…thick…

He wasn't losing his mind and to be fair, he didn't sense any wrong in what he thought. Shockwave may have created him but technically he was more of a caretaker in the long run as Predaking retained his rightful place as leader of the Predacons. And if Shockwave didn't love him, why did he create him so handsome and massive? There was a part of him that thought maybe the scientist changed a few things from the original Predaking to make him more appealing which he wasn't necessarily complaining about.

As his heat levels rose, the Predacon grabbed Shockwave's retreating servo and placed it back on his abdomen. The surprise indicated from the movement of the audial fins was cute and keeping his smirk, he began to drag said servo down farther much to the Decepticon's pleasure but also slight fear. When he started to forcibly massage his interface panel with it, Shockwave could only stare in awe and let him keep control.

"A-are you sure? I would not think you of all bots would stand being with someone of a different type, especially since I am your creator," humbled Shockwave who tried to hide his excitement arising.

Predaking responded by suddenly pressing the smaller bot against him and nipping the audial fins he admired so much. He laughed, "For breeding, no. But for fun, why not? Who cares what you are to me? If you have a favorable interest in me as I do you then that's excuse enough, isn't it?"

The scientist muttered waywardly, "I suppose that is…logical."

Predaking lifted him to straddle his hips and pushed his body to lie on the nearest console. Ironically, the screens of the system held various descriptions and data regarding the Predacon strands of CNA. He merely glanced at it before turning his attention to the purple body pinned under his own as he stood above the mech proudly. With his servos perched beside Shockwave's helm, he gave a pleased rumble of affection before leaning down to briefly kiss the singular optic staring at him with lust.

Biting down on the scientist's neck, Predaking forced open the interface panel which caused Shockwave a brief moment of pain but this faded to immediate pleasure when rough fingers stretched the already slick passage. The smaller bot had been wet for the past Earth hour even before meeting Predaking so he was more than ready but he didn't think the Predacon would do this. He figured he would have to self-service himself later but this scratched that idea.

Two digits turned to three and Shockwave moaned, his single servo clawing the shoulder seams of his partner. His body was reacting way more greedily than he anticipated as he bucked back and juices from his valve lubricated the Predacon's persistent jabbing. His large cannon arm was curled around the thick waistline, keeping him steady and pressing him fully flushed against the monstrous mech with each movement of response.

Predaking growled pleasurably observing Shockwave crumbling before him and he hadn't even gone that far yet. If this was all it took to make the smaller mech submit, he wondered what interfacing would do to the Decepticon. Judging by the reactions, Shockwave had rarely gotten with anybody which meant he was almost as tight as virgin. This concept made him smile gleefully before removing his fingers to listen to the sweet moans of emptiness.

He wanted to know if Shockwave desired him. He wanted to hear the mech plead to his true king. Giving a taunting laugh, Predaking cooed, "Is something wrong? Do you wish for me to continue?"

"Y-yes," Shockwave grumbling, positioning his valve to almost rub against the Predacon's codpiece.

"Yes what?"

"Yes, Master…please," the scientist huffed.

"I'll take that," Predaking smirked. In an instance, Shockwave was lifted and held up by the Predacon before being slammed onto the ground, aft up and chest scratching the metal floor.

The purple mech had one arms clutching the floor while his cannon was posed vertically to help him stay a bit off the ground as he felt his own creation mount him. There was barely any time to register much of the king's intentions but he gave an undeniable yelp as something large penetrated him. At first it felt extremely uncomfortable but just like the digits that had their fun, the spike of the Predacon quickly made its home among his body and he stared between his legs to see part of his lower abdomen swelling from the size.

The power of the thrusts made his kneecaps almost scrape as he tried to keep himself steady. It didn't help that Predaking decided to bite his elbow on the arm with the cannon, almost making him lose his balance. Rut after rut his composure deteriorated and he stared at the monster begging him for more while his voice grew more audibly in ways he never thought he would hear in his lifetime. The great scientist Shockwave, moaning like a post-tournament tribute for the victor of the Gladiatorial Pits of Kaon.

"Who's the pet now?"

Predaking's claws punctured the protoform of his waist but he was too dazed to care or regard the pain. The spike impaled him completely and he felt his entire valve ripple beyond its limits which made him slightly concerned if he would be able to close it after the session. Like a beast, the Predacon showed him no mercy and leaned over his back to assert all aspects of dominance possible. Shockwave did nothing to stop the king having his way, tearing him open because it felt like a proper place for someone like him to be in. It just felt natural.

Loud grunts and heat emitted from Predaking's nostrils that blew quickly against Shockwave's neck and a serpent-like tongue wrapped around the silver audial fins sloppily. He panted, "I want to try something, Creator. If you like me now, I think you'll love this."

Shockwave leaned more towards the ground and gave the king a better angle of penetration before gaining enough energy to whisper, "If…umph…you wish…ah!"

The Predacon stopped mid thrust and pulled out until barely the tip was stuck inside the mech. He gave a light chuckle as he began to transform into his dragon alt mode. Parts shifted and whirred as Shockwave kept still with his aft still ready to go and his head resting on the floor patiently. Predaking heard him give a whimper and a slight jolt as his spike reconstructed to a better format suited for his frame. Since it was still technically inside the scientist, the latter could feel it grow and stretch him until the transformation made it stay at full capacity size.

With a reptilian hiss, Predaking pushed back in and used his limber neck to bring his helm around so he could witness Shockwave's reaction. His massive spike now was only able to fit at most halfway but he didn't push it beyond that because he didn't wish to harm his creator to where the latter would not have any pleasure from him. He wanted Shockwave to enjoy his dominance, submit to his whim and keep coming back for more. Damaging him was frowned upon in his mind.

Shockwave's single optic lit up blindingly bright red and faded more into a pink hue as he didn't move, allowing the mech time to adjust once again. When he felt the other press back despite not being able to fit more and he saw him stare up with a deep moan, Predaking gave a fanged smile and built a rhythm.

For the Decepticon, pain and pleasure mixed well as his valve was stretched way beyond what he thought it could take. Predaking wasn't even thrusting much, just jolting forward ever so slightly and retreating pressure and that was enough for him to crave more. His systems blared warnings while his valve rippled fast to the large intrusion crushing practically every sensory node possible against his walls. His fans did what they could to stall the heat but what was the use?

This was probably wrong on every level…but it felt so good. Years of pent up stress and anger hidden by his calculative façade was about to explode and he kind of couldn't wait to know what the result was. As Predaking gave grunts and growls, keeping almost direct eye contact with Shockwave to remind him of who he was letting fuck him to oblivion, the scientist tried to squeeze as much of the Predacon's member inside him as he could.

Any moment now, his overload would come and Shockwave hated the miraculous build he was enduring but had yet to be released. He gave uncharactistic moan of enthusiasm that only increased in volume until a sudden roar stirred him from his pleasurable idling. Feeling his valve tighten as transfluid was shot deep into his chamber, his sensors could no longer take the charge and he ran his claws into the floor madly as everything became white. He pushed back as hard as he could against the intrusion to keep as much of the stimulation as possible.

Predaking howled as he overloaded and gave another roar, a mix between arousal and happiness as he heard Shockwave finally cave to his desires. The mech below him wasn't very vocal but he didn't care as long as he knew Shockwave was content. He saw the mech place his servo right below his eye as if he was covering a gasping mouth to prevent screams from coming out. It didn't work as he was still pretty loud but then again, who would stop them?

Riding out the remaining waves of pleasure, Predaking pumped a few more times to milk himself dry as Shockwave responded well though grew slightly uncomfortable from his orgasm being drawn out. With a content sigh, Predaking slid out of the mech and transformed, placing his servos onto the floor to steady himself while peering at his creator.

Shockwave collapsed onto the ground but turned over onto his back and opened his valve lips to see the transfluid ooze from its threshold. He didn't mind as the Predacon approached him and nudges his helm with his own. The scientist then brought two transfluid covered digits near his line of sight and studied it in detail.

"Fascinating."

AN: Is it beastiality if the animal can turn into a being who can consent despite originally not being able to do so without alterations? Something to think on, I just said it.

Also, I know it's been a while since I updated but I kind of wanted to get some other stories running. I'm still going to create more content for this, don't worry.
