Chapter One- A Curious Encounter

Knock Out snarled at the mess coating his thighs and interfacing panel, dabbing at it with a cloth in the hopes of preventing his finish being smeared further. Drones were always so lacking in finesse, never could they simply overload inside of him where he could seal it away until the medic had a private moment to wash himself out, no, they just had to get their fluids fragging everywhere. Then they would scamper away afterwards, helms bowed in fear and servos stinging where the CMO had battered them away from himself.

Interfacing was one thing, intimacy was quite another.

Wincing at the part-squeaking, part-squelching sound as he accidentally skipped his rag across his metal, the vain mech hissed, 'disgusting.'

'Finally something we can agree on,' a sarcastic voice droned from the shadows.

Knock Out glanced up, inwardly sighing at the sight of Starscream standing near the medbay doors.

'Must you really do that in here?' The Seeker's wings flared in revulsion.

Narrowing his ruby-red optics, Knock Out levelled a glare at the recently restored flier. Considering the medic had repaired Starscream, replaced his T-Cog for him, Knock Out felt he was owed some respect.

Starscream advanced slowly on the doctor, optics almost maroon in colour, wings raised in warning. Knock Out didn't drop the Seeker's gaze even as his spark began to pulse wildly, fearing for his already marred finish…

No. He had, verbally, challenged Megatron before, he would not back down from the SIC. If Starscream dared scratch him he could comfort himself with fantasies of dissection as he buffed himself later.

The Seeker, however, paused several steps from the medic. For a moment he just stared at Knock Out, expression dark, before he spoke lowly. 'I would not allow Megatron to see me like that, if I were you doctor.'

With that the Seeker turned on his pede and strode out, steps echoing on the cold Nemesis floors, as the medbay doors slid shut behind him.

Knock Out glanced down at himself, realising the vulnerable picture he presented. The drones wouldn't risk touching him, the other officers however…

The thought of Soundwave's tentacles or, Primus forbid, Megatron's claws on his plating made his paint crawl. Perhaps… Starscream posed a valid point and he should try to avoid trysts in the medbay in future.

But using an actual berthroom would suggest a familiarity Knock Out was deeply uncomfortable with…

Maybe a washracks would suffice? Yes, he grinned, two Autobots with one blast; he could get some much needed attention and then clean himself up immediately afterwards.

The self-satisfied expression faded from his faceplates as he thought of Starscream's strange behaviour. Surely he wasn't that offended by a bit of transfluid? After all the stories about the Seeker's prowess in the berth were legendary.

Of course, it may be that Starscream was simply feeling a bit frustrated himself. If so, his sourness was his own fault. Any drone would follow that mech into berth; Pit Knock Out bet that if the flier put his processor to it he could coax Megatron into a fun filled evening one orn or another…

After all, the lecherous gazes the tyrant sent his second spoke volumes so it wouldn't exactly be difficult.

Knock Out, though he typically preferred ground frames, larger models than the Seeker presented, wouldn't mind a night cycle or two himself if Starscream played nicely; that being no deliberate (damage done at the height of passion was tolerated, thought of as a compliment) use of claws on the CMO's finish.

The more the medic thought about it the more he believed it could be quite satisfying for the pair of them.

It seemed unlikely but perhaps, if Knock Out were patient, he could tempt Starscream into berth for a few cycles of lust. It was about time he had a proper new conquest, an actual challenge far beyond what any drone could offer.

It would pose a distraction for the vain mech in the wake of Breakdown's loss, something to focus his efforts on and to stop his unsatisfying meetings with the drones…

Knock Out smirked, optics shining as he continued to work on his appearance, imagining the Seeker's frame against his. Then he sighed through his vents as the fantasy ended with an image of him once more cleaning gunk off his frame.

Grimacing with distaste, he devoted himself more diligently to his task. Interfacing could be so pleasurable, with a decent partner, but the aftereffects were vile, and never worth the encounter if one's companion underperformed.

Starscream's reputation, however, preceded him and Knock Out allowed warmth to settle into his tanks once again as his plating eventually regained its usual unblemished appearance.

The Seeker would be worth the effort, Knock Out was sure of it.

Starscream stared at his reflection in the water, optics studying the form he presented. It had been a long time since he'd truly looked at himself and allowed himself to remember.

To see a time in his processor when he used to be near Megatron's equal in height and, while still agile, his frame had the bulk to back up his speed with strength.

It was not a time he could see clearly but then most of his memory files were long since corrupted, either lost entirely or stored in his processor as fuzzy images, most of which lacked any audio to accompany them. The very few that remained perfectly intact, good or bad, he protected within himself as if they were precious jewels.

The sudden sight of himself in this trickling stream, having left the Nemesis to temporarily escape his Master and his disciples, and the sight of Knock Out freshly… taken, had sent a feeling reminiscent of an electric shock through his energon. He seldom thought about the origins of his current existence, the memories being both too painful and spark-twistingly humiliating.

Still, now his gaze was locked onto the reflection of his own optics Starscream found himself unable to relinquish it. Crouching, he dipped his helm to get closer to his mirror image…

He wasn't grey then, but bold reds, blues and whites arranged artistically on his frame. The only hint of the three colours now were scattered about his metallic body, mostly half-hidden.

Soundwave, he supposed, had done an admirable job, rebuilding him how he did.

That Megatron had undone some of the TIC's work since then was something he believed himself to have come to terms with. What he lost had never provided him with any pleasure, only suffering and a perverse joy for others, so he did not mourn them, not any longer.

It was not as if it were his wings or the sky that was barred to him and, as long as they remained his, the rest did not matter.

With a determined sigh, his wings flicked out and he leapt into a transformation, heading back for the Nemesis grimly. He didn't care how many beatings or time it took him; he would have revenge for what his Master dared to do to him and, Primus knew, savour every moment of it.

Or deactivate trying.

Thanks for reading and please review.

Praise and Acid Rain readers- Sorry for the wait but updates are in the works and should be updated shortly after a couple of university assignments I have.
