The latest offering collapsed into a sweaty heap, their chest heaving, drool trailing from one corner of their mouth. Adept Euler waved two serfs forward to help them step away from the frame that housed their subject for the evening.
“More.” The dreadnought’s booming voice came from deep inside the chassis of his holy form, ringing through the chamber, threatening to rattle Euler’s remaining teeth.
Euler’s associate Tuven approached, wringing her silver hands together.
“That’s all we have.” She hissed in binharic.
“It can’t be.” Euler replied, casting an anxious glance back at their charge. “Another serf at least-“
“There are no more.” Tuven insisted, “And if we try another adept, there won’t be enough of us to field the sacred machines when we disembark from the planet.”
“I may be able to be of assistance.”
Tuven and Euler looked towards the entrance to the arming chamber and saw a legionary approaching. Euler’s ocular augments took in the sight of many campaign badges adoring his armor, as well as the familiar sight of the vox sensors typical of a tech marine.
“I was told you were having trouble settling Ancient Augustus.” He said, pausing before the tech priests, “He was my commander once, and I remember it fondly. It’s been some time since I’ve seen him awake. I’d like to help, if I can.”
Euler and Tuven shared a brief burst of communication over the noosphere, both registering disbelief from the other.
<He can’t mean-> Tuven began.
“I do.” The Astartes said, and Euler detected a note of amusement in his voice.
“My lord, I’m not certain it would be proper-“ Euler began to protest, but the marine raised both hands to his helmet and there was a whine of air as it disengaged. He removed it and set it down on a nearby workbench.
One half of his face was flesh, olive brown and deeply lined around his eye and mouth, giving the impression of a permanent smile. He was still fearsome, like any of his brotherhood, but there was an undeniable good nature about him that was far less common. The other half was holy augments, a deep ruby red ocular lens, a fine cut steel facial structure, and a complex marionette-like design to the oral structure that followed the movements of his flesh mouth as he spoke with remarkable precision.
Euler and Tuven parted so that he could step through them across the chamber to where Ancient Agustus continued to rattle in his frame. The Astartes stepped up to the enormous dreadnaught and reached out one gauntleted hand without fear, resting it on the construct’s leg
“Brother Agustus-“ The marine called, “Are you well?”
It took a moment, but the dreadnaught paused, its great chassis tilting downwards.
“Brother Hiram?” The Ancient bellowed, though to Euler his voice already sounded more calm.
“Remarkable.” Tuven murmured.
“I’m here, my lord.” Hiram said. “I heard the priests are having trouble returning you to your rest.”
“Hmph.” The dreadnaught grumbled, “With such paltry offerings as their adepts and these thin-blooded baselines, is it any wonder?”
“I thought as much.” Hiram said, tracing a slow circle over the plate under his palm. “Would you accept my company, old friend?”
The dreadnaught let out a pleased rumble from his chassis.
Euler and Tuven strode forward, their arms laden with thick gold cables. Hiram crossed the chamber to an armouring frame where three serfs worked meticulously to free him from his armor by removing the rivets keeping him bolted within.
The mechanicus priests had to contend with the Venerable Augustus, his hulking frame continued to shudder and jolt as they sought to plug the cabling into the ports don the front of his chassis. Euler struggled to shove his last cable into the dreadnaught and nearly lost their grip, except that at the last moment, a muscled forearm reached over their head at an astonishing sped.
Euler looked up and saw Hiram’s hand wrapped around the cable. They felt their internal temperature spike, watching in rapt attention as the astartes lowered the cable and plugged the opposite end into the port just above his primary heart.
“Ahh, Hiram-“ The dreadnaught’s voice came out like a purr. Euler could have sworn they saw the space marine’s cheeks color, saw him lick his lips. The adept stepped backwards until they rejoined Tuven at the console.
They watched with rapt, breathless attention, their concentration only disrupted when they felt Tuven press against them, one mechandrite slithering from her sleeve to under their robe.
“Praise the Omnissiah.” She murmured, sliding the connection home into one of Euler’s ports as their charge folded his Astartes partner nearly in half. Euler startled as the truth of just how aroused Tuven had become was transmitted to them through the noosphere.
“Adept-“ Euler began, scandalized that one of their order could be so affected by the sight of any kind of congress. They felt one of Tuven’s hands on their shoulder, nudging them towards the cognitor station.
“I know.” She said, grasping at their robes, “Will you help me purge this weakness of my flesh, my friend?”
Euler shuddered, “Yes.”
“Acknowledged.” She said, and shoved them forward over the desk.
She wrapped her long spiderlike fingers around their most delicate components, bundling them in a fist. Then she thrust forward, pushing her leaking, hard cock within the space she had made for herself inside them. It was utterly wrong, there was nothing within Euler that was configured to accept this intrusion, and yet they felt pulses of sensation through their connection with Tuven in the noosphere.
They let out a low keening sound. Their fellow adept’s cock leaked precome inside them, lubricating its way within them. Wires and coils that had never been meant for organic feedback pulsed with sensation, a rush of data never catalogued by human minds before.
“Yes, yes!” Euler cried out, “Give it to me! Paint my sacred components with your flesh’s filthy seed!” They shuddered from the increasing force of her thrusts.
Tuven’s thrusts increased in speed and they both watched as Augustus drove Hiram to shuddering orgasm after orgasm until he was utterly spent.
The dreadnaught’s fingers slowly uncurled and he let Hiram gently down to the floor. The space marine let out a wordless croon of affection, caressing Augustus’s hand one last time as he withdrew.
Euler and Tuven both felt an enormous wave of relief when Augustus returned to his frame and finally, finally entered his low powered state. Hiram raised both hands and folded them on top of his cum-streaked lower stomach.
“I think that went rather well.” He said, pleased.
