You watched the initiates on screen aboard your battle barge as they struggled in the freezing cold of Strem, a small moon in the Krono system.
It was just one of many traditions in the Ourotors chapter
A large number of unmodified initiates would be dropped off on the frigid world to fend for themselves, only given a heat generator and tools to survive
If they lasted three months in the apocalyptic cold, they would pass and move onto the next trial
Not only did it test their strength and resolve, but also their dedication to the Kroniissiah. Through their hardship and pain, through the loss of limb and life to the cold and sickness, they would understand the weakness of the flesh.
But the next trial was something else entirely
The initiate would be locked a special room and given a bed and other accommodations
It was all a trick of course, as they would be restrained to the bed frame when inevitably caught off guard
The food and drink given would be laced with a powerful aphrodisiac to keep them fully conscious, painfully aroused, slow down digestion and metabolism, and remove the need for sleep
Then a techpriestess of the Adeptus Kroniicus would proceed to pleasure the initiate for seven days and seven nights without reprieve
The trial would only be passed if the initiate managed to not cum

You chuckle, remembering back to when you were just an initiate
You were a regular human then, not yet blessed with a metal body
You had just gotten back from your trial on Strem
You were tired and hungry and not in the mood for another grueling task. Very much reluctant to enter the ceremonial chamber for the next trial.
The techpriest escorting you mentioned several times that it was completely soundproof
Strange, but you figured it was just part of the trial
You entered, but hesitated at first when the door closed and audibly locked behind you
It lasted only for a second before you noticed the food and drink laid out on a table beside a large bed
In your tired and famished state you descended on them faster than a White Scar seeing a dark Eldar
You’d been living off a bland watery soup for the past three months
So every bite of immaculate slow roasted grox, every sip of the sweetest of beverages, was made that much more enjoyable
Once you had had your fill, reclining on the soft and comfy bed, all seemed well and good until several mechadendrites secured themselves around your wrists and ankles, restraining you to the bed.
You hardly had time to appreciate how the silk sheets made your skin sing before out from the shadows she came
A most special techpriestess
Her voluptuous breasts were barely held back by a layer of light armor, jiggling slightly as she stepped forward
Through some miracle of technology they hadn’t created their own solar systems with their immense gravity
You could see her nipples slightly indent the plasteel
Her hips were large and boasted incredible girth, good for birthing an innumerable amount of future techpriests
Her thighs were wonderfully plump and juicy, so much so that even though you had just ate, you could feel your mouth watering at the sight of them
And her ass, by the Kroniissiah, her ass
’Dumptruck’ failed to describe its fullness, its sheer thiccness
The more appropriate term would be ‘Baneblade’
It was wonderfully soft and malleable yet maintained a taught firmness to it
A balance that could only be described as perfection
Every bob of her hips was more alluring to your eyes than any masterpiece painting or stained glass window could ever hope to be
You were certain you could stab a whole straight through terminator armor with the hard on you had now
Which just so happened to be what the techpriestess was focused on
Your pants felt like they would rip if you got anymore hard as she ran a wonderfully soft synthetic digit up your length, causing your cock to throb uncontrollably
Her voice was smooth as silk, every word she uttered was a pleasure to your ears
”Welcome, brave initiate. In this trial you must hold out for seven days and seven nights. I believe you understand what that means?”
You gulped
You had completely many trails in your quest to become an Ourotor—a space marine. You had endured hours of torture of both mind and body; Fought and bested countless beasts from all corners of the galaxy; and survived in the arid desert and frigid cold for months on little more than watery soup and your own will. Yet you knew this would be the hardest trial of all.
You nodded, never once looking away from her alluring body.
She laughed in a satisfied manner, sending chills down your spine
”Mhmhmhm. Well then,” she said, ripping off your clothes, “Lets get started, shall we?”
Your raging election was soon to draw the envy of Khorne as it was released into the air, throbbing wildly in anticipation

Your eagerness earned you an adorable but arousing chuckle
The techpriestess slowly began to undress, her many mechadendrites slowly pulling off her deep blue robe to reveal more of her tempting figure
While she was still a a techpriest, a good portion of her body seemed to remain unaltered by technology
You heard a light pop as her chestplate fell to the floor
Her two forge worlds were released from their metallic prison
You caught of a glimpse of a couple freckles near her collarbone before you were drawn in her by erect nipples surrounded by soft pearly skin
Her skin
It had an odd quality to it. It looked like real flesh but something seemed off
It looked unnaturally soft, and you noticed several places where it seemed to break in geometric lines
Your train of though was forgotten as her mechadendrites quickly spread your shacking legs
You had never been more scared and horny in your life
She slowly crawled onto the bed, silently looking back at you with her cold, unreadable faceplate
Her tits became a hypnotic pendulum as they gently swung from side to side
She stopped when her metallic face reached your rigid member
She seemed to let out a synthetic purr before reaching up with a metallic hand
With a pop she removed her faceplate while your eyes went wide in surprise
Techpriests had faces?
Her face was bizarre. It looked human but there were obvious cracks and lines along it that denoted that same synthetic quality. Her rosy checks were dotted with freckles while her chrome tongue licked her pillowy lips
Her eyes looked to be made with shutters, oscillating in size as they framed two blue dots which seemed to serve as her irises
Noticing your attention she gave you an inquisitorial ‘hmm’
”Like what you see, initiate?”
You opened your mouth to answer but a mechadendrite against your lips silenced you
”A rhetorical question, unproven one. I’ll get to hear you sing praise of my body for a whole week~”
A dexterous hand gripped your member, slowly stroking it from head to base
A long moan escaped your lips as she pumped your dick at an agonizingly slow pace
Her grip was firm but loose enough to make you feel every time her wonderfully soft synthetic skin rubbed against your cock
Suddenly, her hand retreated from your erection
Had a week already passed?
You were nearly brought to ruin as an equally soft mechadendrite snaked its way around your cock before pumping it, continuing the slow and methodical dance from before
You gasped as another lightly fondled tour balls before giving them a light squeeze
”Thought you’d get off easy, initiate?”
Her voice modulator betrayed her arrogant demeanor
This continued for another 30 minutes
She was gradually building you up, every little movement a calculated blow against your will, your resistance
Any other day and you’d have loved to cum in her embrace
But not today
You held out, even when she added a second mechadendrite and began an alternating twisting motion to her two tentacles of terror
But soon she became bored of toying with you with her glorious synthetic limbs
So she leaned forward and took your cock in her hand once more
”You’re done well so far, unproven one. However, many fail this next part of the trial.”
She lined her tits up with your cock before slowly lowering her chest
Her synthetic skin was oh so smooth and soft as your cock slowly crossed the valley in between her two tits
They squeezed you just right in a way that made your whole body quiver in anticipation
”Comfortable, initiate?”
There was her teasing voice again
She seemed to notice how some of your length stuck out from her breasts as she gave the head a kiss, cleaning the bead of precum which had formed there
”An impressive size befitting an Astartes. Let us see if you have the fortitude of one as well.”
She began to slowly bounce her tits on your cock
Every pull and drop of them sent waves and waves of pleasure throughout your cock
Your dick was leaking precum like a broken faucet
All you could think about was how good her tits felt against you
You moaned and moaned, the image of her bouncing chest burned into your memory
Her hands squeezed her breasts harder as she further increased the pace, all but slapping her chest against your groin
Which made it all the more shocking when she stopped, only to wrap her pink lips around your cockhead
She suckled on it gently while her tongue teased your urethra, almost daring you to cum
Soon she took you further into her mouth until all that was sticking out her from breasts was taken in
Like a switch that had been suddenly flipped, her lips formed a vacuum seal as she sucked your cock with unimaginable force
She combined this her chest, bobbing her head and chest in rhythm
Your back arched off the bed as you cried out uncontrollably

Her synthetic tongue was whirling around your hypersensitive head while her breasts strangled your cock, her skin as soft as the silk sheets below you
It felt as though she was trying to suck the cum from your cock by force
Your arms and legs flailed helplessly as she continued to suck without mercy, ignoring your cries of pleasure
With one last effort she squeezed her chest as hard as she could while somehow increasing the already black hole like suction on your cock
You cried out, yelling out what felt like your dying scream as you collapsed against the bed, panting and out of breath
The suction seemed to stop, a good thing too, your voice was hoarse and your cock felt close to exploding
Her lips receded from your cock, making a loud pop as she released it with a kiss
”You’ve done a good job so far, Initiate. But we’re far from over.”

Seven days. It had been seven days of unrelenting pleasure. You somehow hadn’t cum. She had done everything. More handjobs and blowjobs, godly paizuri, mechadenjobs, the most glorious assjob of all time, all done perfectly. All done to make you break. But you didn’t. It was the hardest you had ever tried before, no other experience even came close. You were so close. But she was without mercy.
Her body rubbed against yours as she continued her torturously pleasurable thighjob
Every time her hips rose and fell your dick would rub against her soaking pussy and then her juicy thighs before cratering into her taught asscheecks
It took nearly all of your will not to come
You had to think about something, anything, to distract yourself from the pleasure
She laughed again, a sign that you had come to fear
”There is no escape.”
You let out a grunt and whimper as she crossed her legs before stretching them, squeezing your cock like a hydraulic machine
After a while she released you, seemingly content with your pleasure and pain
You were left a sweaty, panting mess
She stood up, towering over you, while a single mechadendrite snaked towards her crotch
Your eyes focused on her pussy as it teasingly parted her folds
Despite all that she had out you through, she had never once put it inside her
That was about to change
The bed creaked slightly as she straddled you, her hips, thighs, and ass dwarfing you, making you feel as though you would be devoured
Your heart was racing and your cock couldn’t have been more erect
She began to grind her pussy along your length, relishing in the pleasure it gave her
She cooed and giggled at every little noise you made before lifting her hips up, a mechadendrite positioning your cock just below her pussy, your head just barely touching her most outer folds
She leaned forward, her massive breasts shoved right into your face as her hands clung to your shoulders, seeking a firm hold
”Be warned, initiate. Some have died from the pleasure you’re about to experience.”
She slowly lowered her hips, her pussy taking you in centimeter by centimeter
It was impossibly tight and warm inside
Her walls clamped down on your cock with a vice grip
Once she had taken you to the hilt, she wiggled her hips, making sure everything was in place as her pussy mechanically convulsed around you
You let out a animalistic cry, one of pleasure, pain, and the knowledge you were simply not to cum right then and there while every centimeter of her that gripped you begged for your seed
She started off slow, each drawn out raise of hips caused her insides to grip onto you even tighter, desperate not to let you go
Once your head was the only thing inside her, she’d slam her hips down
She’d speed up after every drop until she was pounding away, her thighs and ass slapping against your groin as she rode you
The air became filled with your cries of pleasure as she continued, adding a maddening rocking motion and occasionally grinding her hips while her tits bounced in time with her hips
Your mouth drooled and you felt lightheaded as she shoved her breasts further in your face
Beyond reason and doubt, you latched on and began to suck one of her nipples, relishing the taste of synthetic milk that was as sweet as honey
You popped off, trying to catch your breath only to have her bear down on you more
You felt the end approaching as she further increased her pace
You were going to fail, you were going to cum
Just as you thought you couldn’t take anymore she slowed down
Confused, you looked up from her gargantuan breasts into her cybernetic eyes
The comforting blue lights stared back at you. She was smiling.
”Congratulations. You pass.”
Suddenly, her mouth went from a friendly smile to a wicked grin as her soft blue eyes turned to red pinpoints
Before you could react, her hips started again with blazing speed
The hands on your shoulders tightened their grip, pushing your further down into the bed

You cried out over and over only to have your screams of pleasure muffed as she leaned forward, your head disappearing into her cleavage
Her hips were pistoning up and down like a jackhammer as she relentlessly rode you like never before while her pussy clamped down on your cock for dear life
You could feel the entrance to her womb suck on your cockhead every time she thrusted, hoping to milk you of everything you had
She matched her voice with your muffled moans, crying out with her melodious voice as she bounced on your cock
It was too much
She seemed to know you were close as she somehow increased her frenzied pace
You let out a muffled earth-shattering scream in between her bountiful breasts as you came, your cock pulsing while spurting rope after rope after rope of cum while her pussy convulsed rhythmically around your dick
She continued to ride you through your orgasm
You came and came and came as she continued to bounce up and down on your cock while she cooed and rustled your hair
”That’s it. Let it all out.”
It felt like every cell in your body was in euphoria, indescribable bliss flooding in from your cock
Your orgasm seemed to last a whole other week as she never let up, continuing to ride you for all you were worth
After what seemed like an eternity she finally slowed down and stopped before giving you a few slow bobs to make sure you were fully spent
You vision was slightly fuzzy, your ears were ringing, and you felt like you had fought your way through a daemon world and back
You watched as she gently got off you and stood up, your seed spilling from her pussy
She turned around and headed for the door, giving you another good look at her superb ass
No
She wasn’t going to just up-and-leave after what she had just done to you
You were going to get her back
As she reached for the door controls you sprung up with newfound strength and pinned her against the wall
”Wha—I-initiate, what are you doing?”
”Paying you back”
You forcefully shoved your cock into her, earned you an arousing moan from her
The mechandrites which had risen to defend their master fell back limply
You began thrusting into her welcoming pussy, enjoying every time your hips connected with her plump ass as you roughly groped her magnificent breasts from behind
Her moans became more static as her voice modular struggled from the strain
With one last thrust you felt her orgasm, her walls convulsing around you once again as she let out a static filled scream
She leaned against the wall, struggling to stay upright
”Hah....that was good....but I have to be going.” She had said shakily
Not so fucking fast
You began thrusting again again with even more conviction
You weren’t letting her go anytime soon

It had been a month since you encountered her, and in that time you’d become a full fledged Ourotor, devoted to the Kroniissiah. You had celebrated with your fellow battle brothers all day, but now things were winding down. You had made your way back to your quarters, thinking about her.
You must have continued for what must have been days, her cries of pleasure a memory you would never forget. She had left a broken but satisfied mess. Her voice modulator had fried; several mechadendrites were bent completely out of shape or rendered useless; most of her joints were in need of repair; and she walked with an obvious limp. You’d fucked her good.
Once your lustful craze had abated you immediately had helped her up
You felt guilty for leaving her all messed up but through some hand signals and spliced audio files, she told she was fine, she enjoyed it as much as you did
She just needed some repairs
She truly was something else
You opened the door to your quarters, a modestly sized room with a stand for your armor and a large bed
You were about to relax and take off your armor when you heard a knocknat your door
You opened it only to be surprised by her standing in the doorway
She appeared to be in far better shape than when she had left
A mechadendrite slowly spiraled up your leg
”Would you care for another round, my lord?”
You’d love to but you’re worried you might break her again
After all, you’ve only gotten stronger since then and you didn’t want to seriously hurt her
She sighed, “I appreciate your concern, but its not a major issue. I can always get repaired did you’re a little rough like last time. Besides, my father is a Magos.”
She stepped forward, rubbing her hand against your codpiece
”That reminds me. He’d like some grandchildren.”
Well, it would be rude not to abide by his wishes
Besides, it would be a week before your first deployment
And you were sure it enjoy it to the fullest
