Pairing: FOC Shockwave/Grimlock

Rating: Explicit

Details/Themes: Sexual slavery, alternate outcome of the Grimlock Smash level

"Now sit there like a good pet, while I finish my work."

Grimlock remembered that. It stuck to him as he was forced to see Shockwave complete his space bridge technology. He had used far too much of his strength getting to Shockwave in the first place that the electromagnetic restraints keeping him from ripping the scientist apart did their job well. He hated how he obeyed like a cyber-mutt and did nothing but watch the Ark and the Nemesis leave while Shockwave's machine raged on. He was then escorted in chains back to Shockwave's lab, saddened as Slug and Snarl were already rounded up and Swoop was in a cage.

The next thing he knew, he was restrained with some type of collar on a slab with none of his teammates there and an empty, lonely room to think in. Of course, it didn't spare him any peace when Shockwave came in finally. His lowered intelligence didn't reflect well trying to speak to the Decepticon as the smaller mech referred to him not by name, but by the term "pet" in some way shape or form. At some point, he began to believe it as only a mindless pet could fail like he did.

"Now, my pet, come serve your master," Shockwave said.

When Grimlock hesitated, he got shocked. He roared with fury but didn't dare transform. Slowly, he approached Shockwave as the latter gestured for him to kneel and get on all fours. He obeyed but winced internally as Shockwave laughed.

"Such a good pet. You deserve a treat for being so nice and cooperative today. Do you want what I'm going to give you?"

Grimlock barely nodded but it was enough for Shockwave to acknowledge and stroke the underside of his chin. It was utterly humiliating but there was nothing he could do and he was hoping the others weren't subjected to this either. He would rather take the full punishment or reward than let the cruel scientist have his way with them.

It was always the same thing Shockwave wanted from him. Sometimes, he was strapped down and experimented on to test his limits. Other times, it was Shockwave making him use his servos or his faceplate to satisfy his aroused needs. How sick and twisted Shockwave truly was seemed unfathomable until now, and all Grimlock could do was sit and obey.

The reward today was letting Shockwave ride him hard. Only good thing about having the newfound instincts of another creature was it made the ability to adapt and rut quicker and morals he was supposed to recognize blurred heavily. He didn't mind hearing Shockwave moan much, just the action of interfacing was less satisfactory in his mind...not to his body however.

Watching his spike being drowned in the purple bio lit valve was driving him crazy. Just for the feeling alone, he would rather take control and destroy Shockwave's valve hard in his own style, but the restraints he possessed chaining him to the berth was making it a little difficult to bring the idea in fruition. Primus forgive him for giving in to this terrible mech.

"You are a leader, mighty and huge. Aren't you happy I found you, turned you into a beast? You're all powerful! Just look at what you're doing to me," Shockwave purred, grinding himself down against Grimlock's large member.

The Dinobot growled low, wanting to snap at Shockwave but it instead came out as a forced moan. The side panels of his chest expanded to let the buildup of steam from his engines out before he overheated.

"You like this, don't you? Your pride says otherwise but deep down, I can sense you do. You are nothing but an animal, so I will treat you as such and I have to say, I'm liking your primitive thinking. So easy are the instincts of fools to be controlled and submissive with a little interfacing and some desperate emotions. I always held fascination with you and now, you are mine."

Shockwave didn't know scrap but it wasn't like Grimlock could argue with his spike being tormented like this. His animalistic grunts were only proving to the mad scientist he wasn't in his right mind anymore. Gone were his deductive attitude and intellectual reasoning. The only thing remaining was a pet for someone to use.

Shockwave filled himself with his spike and shivered, clutching his abdomen with abandon. Grimlock felt disgusted with himself letting this happen. Then the feeling became worse when he overloaded into Shockwave and the latter only continued to ride out the sudden burst of transfluid.

"Bad boy, overloading without permission," the Decepticon snarled, grabbing Grimlock's collar. "But don't fret, I have plenty of time to train you to refrain yourself until I command you. You won't do it again, my pet?"

Grimlock mumbled something but gave up halfway through when it became apparent words were no longer his strong suit. He only said, "No."

He grimaced inwardly when Shockwave pulled himself off the spike and went to the side where Grimlock couldn't see. When the scientist returned, he carried some sort of large ring in his servo. Suddenly, Grimlock roared in discomfort as the ring was placed on his spike and forced down to the hilt. The pressure hurt like hell and he glared at Shockwave.

"How about an experiment?" The mech said in a sultry manner.

For once, Grimlock was afraid of just what Shockwave was planning. He got part of his answer when the mech straddled him again and realigned himself with the sore spike.

"How long can you last not being able to overload?"

It was like a nightmare when his spike was taken again. His entire system was showing signs of release...but he couldn't. Then warnings of stalls and risk of damage were popping up. He felt like his abdomen would rupture at any given moment from all the pent-up pressure he couldn't get rid of. It was more than the torture he endured being turned into a beastformer.

Shockwave ignored his plight, his whimpers as he was lost milking Grimlock dry and satisfying his sick desires to a tee. The valve contracting and the ribs of his spike hit every inch of those walls was driving him insane. Envy wasn't something Grimlock usually experienced but at the moment, it was the only thing he could feel bearing witness to someone else being pleasured while he stayed pained.

"Good-ah-good pet! Y-yes, right there! Good pet, good boy," moaned Shockwave.

Grimlock lied there in agony as Shockwave was in bliss. There was nothing to do except be a good pet to the scientist he hated. If he ever got loose, he was going to kill Shockwave if it was the last thing he'll do.

AN: I had to, the moment in that game read to me Shockwave wanted him so bad like a pet so this monstrosity was created. You're welcome!
