Sparks: Chapter Four

Slowly, Orion's systems came back online. He felt the warmth of another at his side, hot metal fitting into his seams. Orion ever so slightly shifted to get a feel for the one beside him.

"I know you're awake, Orion." Megatron's deep voice interrupted the peace. Lip plates gently connected with Orion's helm. "Do not think you can deceive me." Sharp talon servos traveled up Orion's frame.

"I wasn't trying to deceive." Orion powered on his optics. "I merely wanted to savor the moment." He turned to face his berth partner.

"There will be other moments, Orion." Megatron leaned over Orion's form for a deep kiss. "You will not escape me anytime soon."

Orion stretched lazily, releasing tension built up in his gears. "Do you not have to see to your army?"

"I shall in an earth hour or so. For now, I see to your needs, old friend." Megatron gave Orion a wicked smirk. "All I need is to know your spark's desire."

Orion chuckled. "Very well." He looked at the door. "How about a hot ion shower?"

Megatron gave Orion a kiss. "But that would require leaving the berth." The dark lord teased as he brought his servos up to gently claw between Orion's armor to nick sensitive circuitry. Megatron shoved himself between Orion's legs to grind their pelvic plates together. Orion shuddered beautifully beneath him.

Orion lost his line of processing when Megatron leaned down to nip at the chords of Orion's neck. Orion brought up his own hands to gently pry beneath the seams of Megatron's armor. He knew that Megatron lacked any outside sensors that would properly code pleasure. As a gladiator in Kaon, the more logical route was to simply remove such weaknesses.

Orion challenged himself early on in their relationship to find the hidden pleasure nodes tucked away from sight. Orion knew the ones under Megatron's shoulder spikes made Megatron moan for him, but times changed. Worried his touch might have the same effect as before, Orion hesitantly pushed his fingers beneath the spikes to protoform beneath.

Megatron released a loud groan. "I forgot how determined you can be in the berth." Megatron said almost breathlessly.

Megatron felt his spark surge with a long forgotten, yet still powerful, desire. He'd forgotten what it was like to have his touches reciprocated, for so many of his recent partners simply allowed Megatron to lead the dance. The electric fire running through his lines from that simple touch undid a bit of Megatron's self-control.

"Give me your spark, Orion." Megatron half-ordered, half-pleaded.

Orion shook his head. "I want to please you first."

Megatron gasped as if he'd been struck. The more confident Orion dug deep under his shoulder spikes, clawing gently into the long untouched bio metal beneath. Megatron shuddered over Orion, feeling the touches all the way to his spark.

"You always please me, Orion." Megatron said, losing his control yet again. "And only you could be so bold." He leaned down for another kiss.

Megatron decided to return the favor. Luckily for him, while Orion's battle frame did indeed include its own set of challenges, Megatron knew all too well how to seek and destroy such delicate lines. In this scenario, however, Megatron used his knowledge to find the bundle of sensors found at the intersection of Orion's back strut to his hip plates.

Orion let out a strangled moan. "Megatron, please, I'm trying to please you."

Megatron laughed menacingly into Orion's audial. "Oh, but it pleases me to please you. I do enjoy how you shudder for me."

Orion did just that as Megatron dug deeper. Orion's hands in turn gripped tighter into the protoform. Megatron hissed at the painful pleasure Orion incited.

Megatron growled into Orion's neck cables. "Give me your spark."

Orion could only nod his helm. With a click, his chest plates gave way expose his spark. Megatron released his own burning spark. Orion shivered as their energies sought each other out, pulling towards each other with need.

Megatron surged forward, clashing their very essences together. Sparks flew from their combined desires. Orion cried out, pulled Megatron closer. Megatron pulsed into Orion, sending a flare of his yearning into Orion.

Orion surprised Megatron by taking that yearning, adding his own need into the blend, and throwing back at Megatron. Megatron hissed out, "Give it all to me!"

Orion cried out as Megatron pulsed into him again. Orion took that power within to mate his bliss with it, sending it back to invade Megatron's spark. Megatron let loose a groan, taking the golden line of ecstasy to pour his ambitious affection beck into Orion. Back and forth, over and over, their sparks swirled together, faster and faster. Orion let out a long cry. Megatron roared. The pleasurable emotional power of their shared want burst into a supernova took them over the edge, making them one.

Orion slammed back into the berth. His cooling fans kicked on as Orion struggled to catch his breath. Megatron huffed into Orion's neck, needing time to regain his own control. Megatron closed his chest plates first, hissing when the heated plates touched at the center. Circuitry still running on high, Megatron slowly sat up to stare down at his conquest.

Orion laid there before him, still exposing his blue light through the room. Megatron smiled down as he saw the impotent Matrix of Leadership staring back at him, dead without power. All that was left was purely Orion, the mech that Megatron longed for centuries to hold again just like now.

Orion slowly closed his chestplates, letting out a small moan as his plates met. Megatron chuckled. "Sensitized?"

"Yes." Orion nodded. "I don't think I can move."

Megatron got off the berth. "Then I shall take you to your spark's wish."

"Hmm?" Orion allowed Megatron to gently pick him up bridal style. "Where are we going?"

"You said you wanted a shower." Megatron smirked. "I happen to have the best wash racks and bath on the ship."

Orion shuttered his optics as he rested his helm on Megatron's ches tplates. He could hear the spark whirling beneath it and feel the remnants of their shared heat. "I think I'd like that."

Megatron walked through his massive chambers into the wash racks. He set Orion carefully onto his pedes. Orion trembled slightly, but managed to stand on his own. Megatron turned the ion shower on, fiddling with the temperature settings a little to get it just right.

Orion stepped forward. Tilting his head back, he let the spray splash against his face plates. Megatron felt his spark heat up yet again at the sight. Orion looked positively enraptured with the feeling.

Megatron quickly grabbed a cloth. He needed to focus. They did have work to do, and as tempting as the idea of keeping Orion locked in his bed chambers all day was, Megatron wouldn't allow his spark to run his processor. Megatron quickly wiped down his face, moving onto his shoulder spikes and chest.

Orion's small voice interrupted his efforts. "Would you like me to get your back?"

Megatron paused to glance at Orion. The mech looked so sincere, so utterly innocent. Megatron did not make it a habit to turn his back on anyone, a fact Orion well knew, which is why he asked so softly. Orion waited, giving Megtron the time he needed to decide. It struck Megatron that Orion fully knew what he was asking. He understood in a way that no other mech ever could.

After all, only Orion heard the confessions late in the night on Cybertron. The haunting fears Megatron still kept from the tortures of slavery and oppression continued to even this orn. It occurred to Megatron that to Orion those confessions weren't centuries ago, but only a mere few cycles ago.

Slowly, Megatron extended his cloth. "Yes, I would like that."

Orion took the cloth in his hand. He smiled up at Megatron, "If you want me to stop, just tell me, alright?"

Megatron nodded. He turned on his heel, giving Orion full access to his back. Orion told him, "I'm going to touch you." All too gently, Orion placed the wash cloth on the warlord's back. In slow circles, Orion rubbed away the dirt and grime off Megatron's armor.

Megatron tensed with each motion. However, he needed to do it. By showing Orion that he trusted the librarian, Megatron endeavored to keep Orion trusting in Megatron. Megatron supposed he could've found a better way, but that traitorous part of his spark told him this way kept Orion close. Besides, he was in no danger from Orion here.

Orion moved lower, moving towards the hip plates. "Would you return the favor?" He asked again, oh so softly.

Megatron gave a small huff. "I suppose it wouldn't inconvenience me, since that means I get to touch your frame again."

Megatron was not all that surprised when Orion came around to face him, slapping the cloth onto Megatron's chestplats. "We have work to do if I may remind you, my lord."

Megatron took the cloth off his chestplates. "I am well aware, my clerk." Megatron shoved Orion's shoulder to make Orion give his back. "But is it so wrong that I enjoy what little time I have left with you?"

Orion muttered, "I well remember your definition of enjoy, Megatron. I enjoyed it, too, just a moment ago." Orion gave Megatron a glare over his shoulder. "That is not my back."

"Oh?" Megatron continued rubbing Orion's aft. "I thought it was your backside."

Orion turned around to give Megatron a knowing look. "I need to return to Project Iacon."

"And I must return to my army." Megatron started rubbing Orion's chestplate. Orion shivered under the touch. "Yet, I'm not disinclined to another round."

Orion let loose a resigned sigh. "You're insatiable."

Megatron leaned down to kiss him. Orion kissed him back, nipping at Megatron's lips plates. Megatron snickered. "Careful, Orion. I bite back." And so he did, nipping at Orion's lip plates, drawing a little energon.

Orion gasped at the sudden pain, but didn't protest. Megatron licked at the small wound, as if apologizing for the slight hurt. Megatron rubbed harder on Orion's chestplates. Orion shook at the pleasant strokes against his armor.

Megatron leaned his frame close to Orion's. Already warmed up from their previous bout, Megatron managed to open Orion's chestplates by pulsing his spark energy into Orion's frame. Mingling their sparks slowly this time, Megatron pulsed long bursts, letting the heat build up.

Orion trembled wonderfully as each pulse brought him closer and closer to completion. Megatron held him tighter and tighter as Orion sent back his own warm need. When their overload washed over them like their shared ion shower, Orion shuddered beneath him.

CRASH! Orion's legs promptly gave out.

Megatron doubled over in laughter. Orion looked put out, lying on the floor with his spark still exposed. Megatron closed his chestplates. Quickly, Megatron came down to the floor to kiss Orion's pout away.

Megatron picked up Orion bridal style again, still shaking with mirth. Orion continued a small displeased look as Megatron set him in the bath. Megatron kissed Orion's frowning liplates to try and hide his smile. "I apologize, Orion. I was merely caught by surprise." Orion fit comfortably into the bath. Megatron turned on the ion valves.

After their second round of merging, the mech looked like he could use a nice rest from Megatron's affections. Besides, the crash obviously hurt his pride. Yet, always the forgiving mech, Orion seemed a little mollified after the apology and the warm ions floated over his frame.

Megatron informed Orion, "I must return to my active duties. Call Soundwave should you require anything. Feel free to take the energon from my fueling station." He leaned down to give Orion a kiss. "I shall see you at the end of this solar cycle."

Orion smiled up at him in that gentle way of his. "Don't work too hard, brother. I have a feeling you want a repeat performance."

Megatron turned away as he gave Orion an ominous chuckled. "I shall endeavor to give you my best show tonight, old friend." He gave Orion a smirk over his shoulder before he left. "I'll make sure to wear you out properly, next time."

Megatron walked with Soundwave towards the bridge. "As much as it pains me to admit it, the return of Orion has gifted me with a sense of kinship I've long been lacking. Not to mention, the closest I've ever come to inner peace is in his presence."

Megatron gave forlorn sigh. "Alas, I know that within his spark is a mech worthy of defeating me. I must destroy that mech before he awakens within Orion."

Soundwave said nothing, only watched as Megatron stared at the screen displaying a busy Orion Pax, back at his work station and clacking away at the keyboard. Almost unnoticed, Megatron left hand moved up, as if to reach out.

Only to clench, returning to Megatron's side, balled ready to attack.
