Call Me

Optimus sighed heavily as the multiple stares settled on his frame, adding to Ratchet's angry one.

"Well? Say something you slaggin' glitch!"

Prime muttered his response, unheard over Ratchet's growling.

"What?"

Again an indecipherable mumble.

"Prime, you've already worn out my patience...what the frag happened?!"

Optimus snapped, spinning on his heel"I thought the sparkling had offlined! There, happy! I said it!"

Even Ultra Magnus took a step back from Prime, the mech's optics narrowed and raging as he glared at the now still medic.

"After the base was blown Pit high Ratchet I thought I was dying, that the Matrix would go to someone else as the new Prime...I thought the sparkling had offlined instantly upon the explosion..."

Ratchet sighed heavily, crossing his arms in front of his chest before meeting Prime's not only frustrated and stressed gaze, but a pair of optics that held a faint longing.

"I understand Prime...but that doesn't excuse this...a 'Con for Primus' sake Optimus...I don't even know where to begin with this..."

Optimus ducked his own head, shoulders slumping as much as the new armor allowed.

"Begin with preparing a containment tube."

Smokescreen spoke this time, "Containment tube? Optimus sir...that's for deceased autobots, what does that have to do with your sparkling?"

"Because the sparkling won't survive to term."

The autobot medic stepped forward, pausing when Optimus retreated in response, "Won't survive? Optimus, please don't tell me...our species is dying...you're not considering...terminating the sparkling..."

Prime shuddered, armor rattling against his frame and making his fellow bots cringe, "No, it would be of no use...during...conception...the new spark did not receive the proper amount of transfluid and internal spark energy to successfully form...the sparkling will not live much longer..."

Ratchet let Optimus walk away after that, the mech going through enough as it was.

"Oh primus..."

Optimus initiated his private comm screen, sending an urgent request to the recipient.

The tired silver and red face with the dark scarlet optics met his own gaze.

"Yes Prime? Dare I ask what is so urgent that I had to lie to Megatron himself to slip out of my med bay?"

"I'm sparked."

Knock Out sighed, growling as he ducked his head and wiped a servo down his face plates, "Oh frag..."

Prime couldn't help it, his mood was down enough as it was, "That 'frag' is what got me into this!"

"Calm down! I'm just...oh primus...that means you conceived when..."

"Yes."

"And that means the sparkling..."

"Yes."

The 'con sighed again, turning slightly from the screen to abruptly punch the nearby wall.

"When and Where?"

"Excuse me?"

Knock Out rolled his eyes, shifting to set his hands on his small hips, smirking a little as Prime's optics followed the movement.

"When and where do you want to meet to finish this? I know that if you have the gall to risk calling me outside of the set times that you obviously aren't going to terminate the sparkling..."

Prime instinctively placed a servo over his chest plates, protecting the unborn without fully realizing it.

"Thought so...I know you Prime, you're going to tear yourself apart if you have to wait for this sparkling to offline...and I..."

Optimus looked up, seeing Knock Out staring at nothing, processor lost for a moment.

"I can't let that happen...especially not to you and our..."

"Our?"

Knock Out sighed at Prime's almost deadly tone, but nodded anyway, "Yes our...you've just inadvertently made it so I can't attack an autobot ever again on this planet or ever...not if it meant harming my sparkling. Pit, I'd be worse than dead if Megatron found out."

Optimus nodded, backing up slightly to sit down heavily, rubbing a servo over his face plates in thought.

"So I ask again Optimus...when and where do you want to meet?"

Prime shook his head, processor buzzing to come up with a decent answer, he hadn't noticed the lock on his door had been opened with an override.

"I'll send you coordinates in a moment Knock Out, you'll meet me there and then be bridged to our base, that way you'll be under our radar and not that of the other Cons."

Knock Out shrugged at Ratchet's demands, stepping back from the screen to let Ratchet address Prime without him "hovering".

"You stay here, Magnus and I will bring him down...Knock Out's right...none of us can watch you tear yourself up over this."

Optimus merely nodded once, not looking up as Ratchet typed the information into his computer before leaving after Knock Out cut the link.

The Prime sighed yet again, intakes shaking in a mix of emotions that just couldn't be described, he stood as he heard the familiar hum resonate through the base of a ground bridge activation.

The sparkling, while small, initiated a round of sharp cramps deep within his frame, making him hunch over to combat the pain. Already the sparkling was deprived of essential coding and energy that it needed to survive, and was letting its Carrier know.

It hadn't even been ten minutes before Ratchet let Knock Out into Prime's quarters, nodding to his leader just before the door shut.

Knock Out stepped closer to Prime leaning on his desk, a servo over his throbbing abdomen as he remained hunched over.

"It's started already, hasn't it?"

Optimus jerked his head in a sharp nod, unable to move much more than that as Knock Out stepped forward, hands resting on the red chest plates, either to comfort or examine...

"You need to relax...I can't do this unless you do...you'll get hurt...both of you..."

Prime groaned, shaking his head as he staggered to his berth. pulling himself onto it and leaning over, frame shuddering to contain the retching his tanks wanted to emit.

Knock Out sighed, dimming the lights to the point the only real illumination in the room was the two pair of optics gleaming.

The smaller mech stepped closer silently, digits warming and gently rubbing Optimus' arm plating.

"Do you want this?"

"Huh?"

"Do you want this Optimus...do you want me to do this...it could cause irreparable damage..."

A low sigh, drawn out with the slow start of the powerful diesel engines, "Y-yes-s...j-just-t...I-i...can't-t..."

Knock Out nodded, switching to rubbing the larger mech's long legs, feeling the barely contained shaking beneath the plates. "I know...I know...just let me...you'll be fine...it's alright..."

The Con was surprised how relaxed he was about this, he was about to marginally frag the Autobot Leader, to save a dying sparkling that its offlining could kill its carrier, and he was doing this in full knowledge of the other bots...that and the infamous Optimus Prime was too weak to do anything...

He was so slagged if Megatron found out...

Knock Out continued to murmur soothing nonsense to the larger mech, stilling the shaking as he massaged the armor with heated servos, climbing into Prime's lap as the mech shifted his own servos to brace against the edge of the berth.

"Relax...just relax...sweet rims...relax..."

Optimus made a noise similar to a whine, face plates closed off and unshowing, but he bowed his helm anyway, resting it on Knock Out's shoulder and giving in to the Con's ministrations.

Knock Out ducked his own head, nuzzling Prime's neck before nipping at the protoform exposed behind the taut cables. The simple action made Prime groan and shudder beneath the Con, his own mouth plates beginning to mimic the action on Knock Out's neck, hesitant and uneasy.

A comm ping hit Knock Out hard, making him growl slightly, masking his frustration by outright tipping Prime's head and attacking the slow mouth plates of the mech.

:Megatron to Medic Knock Out, where are you?:

:Occupied my Lord, I am barely within comm. range.:

:Why are you off my ship in the first place?!:

The yell within his processor made Knock Out cringe, instinctively biting down on Prime's probing glossa, this started the diesel engines revving and vibrating. Knock Out pushed closer, letting his own engines pick up the diesel's rhythm.

:Personal reasons.:

Megatron didn't like that, but withdrew from Knock Out's comm. line, shutting him down, the Con shivered in relief, pulling back from Optimus to kiss and nuzzle the broad shoulders.

Prime still hadn't moved his servos, unable to let go without risking falling, Knock Out compensated, digits tracing the back plates before slipping underneath to attack the sensitive hip joints. Optimus bucked slightly beneath him, groaning in both pleasure and pain, gasping for air as the Con forced him to lay back, helm banging against the wall harshly as the armor clanked against the metal berth.

Ratchet must have been standing guard outside, his loud growling followed the sharp knock on the door, a warning for Knock Out to watch his actions.

The Con ignored the warning, straddling Prime's hips as he massaged the joints and cables beneath the armor, Optimus groaned again at this, definitely in pain.

Knock Out leaned down, kissing the false glass spread over the mech's chest, "Easy little one...it's alright...just wait a few more moments...everything will be alright."

Optimus didn't seem to hear, helm rocking back and forth slightly, whether combating the pain or riding the pleasure readings flooding his systems...the Con couldn't tell, but it meant Prime needed him now.

He ducked his fingers under the heavy armor over Prime's interface panels, feeling for the sensors and growling when he realized his dilemma...the armor upgrade had locked the panels down even tighter.

"Prime...open up...everything's going to be fine..."

The panel shifted marginally, enough for Knock Out to manually unlock it before quickly undoing his own. Prime was barely breathing at this point, nothing good was hitting him now...only the sparkling's deprivation induced pain.

"I'm sorry sweet rims...this is going to hurt..."

The port opened smoothly, revealing the valve Knock Out hadn't seen in several weeks; it wasn't tight, but it wasn't slick either...meaning Knock Out's spike penetrated hard and rough, making Optimus buck in sheer pain.

"Sshh...easy my love...relax..."

Optimus didn't hear, leaving Knock Out to quickly build up the charge within his own systems without hurting the larger mech too much. Knock Out knew he was going to regret this as he shifted a servo to remove a syringe from subspace, his other servo was gently but firmly building Prime's end of the charge. The needle was jabbed into Knock Out's lower abdomen, emptying the contents into the one part Knock Out really hadn't wanted to jab with a sharp object.

The effect was immediate, the built up charge overloaded as Knock Out flooded Prime with the electricity charged transfluid. Optimus groaned at the action, unable to do anything but ride out the pain.

Knock Out was breathing hard as Prime fell into stasis after the overload dispersed, but the medic couldn't allow his own systems to shut down. The syringe contained a stimulant, activating his transfluid generator to work overtime. A spark merge would kill the sparkling, but flooding the unborn cybertronian with highly charged transfluid would allow it to gain enough coding to develop properly.

Optimus might as well be unconscious, Knock Out's systems were recovering much faster than normal, but the sparkling and Prime's well being depended on it. The Con's own charge was just starting to stir Prime's unconscious one when the larger mech's frame was lightly shaken by the sparkling protocols, cramping for its deprived needs.

Knock Out chuckled, rubbing a servo over the still chest plates, "Easy little one, let your Sire finish...you're just fine..."

The cramps ceased, allowing Knock Out to continue undisturbed until he was exhausted and out of the willpower to move, he'd given Prime enough charged transfluid to technically conceive several sparklings. Hopefully it was enough to save just one...

The Con didn't know what he'd do without Optimus...
