Author's Note: The following is a short N/J oneshot smut based around the concept of murder drones being like artificial animals and being designated as a breeding pair. Somewhat inspired by the various animalistic DD fics, specifically "(The Terrifying Tales of) Tessa and her Murder Pack" by The3BozosMurmerDroning.

"Those things do what!?" David yelled out.

Jason turned to his companion, "Do you really want me to explain?"

These are both human workers, assigned to watch over the containment of three prized yet very deadly subjects, the murder drones.

Machine workers have been a common presence for humanity for some time, serving as effective servants for various kinds of tasks such as simple employment or manual labor. But soon, as humanity does, ideas for how to weaponize such a resource made way for what became known as "disassembly drones" or often referred to as "murder drones". Similar to the worker drones before but built for combat and mixed with animalistic data for enhanced functions.

While used across the world as a safety measure as basic soldiers, many companies keep more advanced models to themselves for the next best thing, competition. Like gladiators, these companies have murder drone squads regularly compete with each other for entertainment and sway dominance between them. While some rights activists try to protest this usage, murder drones are fair more like higher IQ animals rather than the more human-like worker drones.

This particular company remained high in the hierarchy, thanks to their own signature murder drones. Known for their great displays of skill and many victories in battles between these competitions.

N, their sole male subject, a surprisingly cordial murder drone who was never much trouble to keep in check. His agreeable attitude made it easy for the local scientists to study murder drones for more fundamental purposes.

V, a female drone crazed for battle, hard to keep in check but valuable in keeping them on top.

J, the leader of the pack with her cold demeanor and viscous streak. She's prized by the company for her effective abilities in these competitions and remaining reliable to her masters, although with some difficulty here and there with her aggression.

Jason and David work for this company and are responsible for maintaining their pack of drones, David being more new to the position and following his coworker's lead. Leading to days like today where David starts to learn something new...

David looked nervous, "Well I mean...these things have a breeding season?"

Jason pushed up his glasses, "Yep. Whatever weirdo designed these things really wanted them to embody Earth's lethal predators, and apparently their mating habits factored in as well." He turned and walked down the hall, letting David follow after him, "It's fairly rare and the murder drones themselves don't give much trouble about it either, more trouble than usual anyway. They go into a heat but it's nothing they can't handle, most under captivity barely even show discomfort."

David hummed, "I guess it wouldn't be very effective if these hunters had to stop and roll around horny in the middle of duty."

His partner nodded, "Crude but yes, if anything it's more like the functions are there to remind them of the possibility rather than enforce it. Under our care, N remains the most affected but he can shrug it off when we need him to. Legally they're banned from breeding anyway as a way to prevent their numbers from growing unregulated and without more proper supervision...yet..."

Jason paused, thinking before answering, "Our higher-ups want to let our's breed."

David blanked, "WHAT?! You just told me it was banned!"

"The ones uptop make the rules here, we just follow them." Jason explained, "They've been paying some more direct attention to the murder drones' performances this year and, while V and J still remain extremely successful specimens, N has finally been deemed to have been underperforming. They want a new one that's more effective without the hassle of ordering a new one made as a replacement or trying to convince some kind of trade."

David nodded along, "That's harsh, N's pretty cool...for a robotic monster thing. But alright, he's getting laid then. With V, right? Those two seem somewhat close enough, at least from N's view I think."

"No, they want him bred with J."

At his words, David shook his head, "Wait, what!? Don't they pay attention, that stuck up princess hates N. There's no way she'd let him touch her, let alone knock her up."

"I know," Jason groaned, "I even explained that J's far more resistant to the heat of mating season than V is, she barely even shuffles around let alone is desperate enough for N to be her partner. But in their eyes, they'd rather have another specimen potentially like J than another V."

"That's fucked up."

Both made it to the containment era, staring out a window into the room where the three murder drones wait in their cages. J sits in the corner of her cell, licking her claws free of oil from a recent meal. V is seemingly trying to sleep, curled up on the ground but having trouble finding rest (likely from starting to feel heat). N padded around his own cell, looking a little restless.

"Orders are orders. Put them in stasis and bring them to the lab cells, I'll prep them with a lease to keep them in close contact and give them something to act up their sex drives. N'll comply but we'll have to force J to be submissive to him."

Hours later, the stage is being set. N and J had been sedated and prepped for a potential union, their settings meant to signal mating season enhanced and both fitted with large metal collars, seemingly lacking a chain. Both have been placed within one containment cage, filled with vegetation to build the illusion of an isolated forest environment.

The pair of workers watch from a monitoring room, computer screens on display to keep watch on their subjects and a control console in front of them. As they wait for the slumbering drones to awaken, David asks, "So how are things supposed to go."

"Well, while breeding is banned, some companies will still allow their murder drones to mate. Likely to help relieve their stress," Jason answered, "When that happens, typically the pack leader will go to a potential mate and...well you know. However, our pack is uniquely the only one run by a female murder drone instead of a male, one disinterested in mating so we don't know what may happen."

David looked at the sleeping J, appearing as normal though with her stinger tail removed for the purpose of caution, "Well I think the chances are that she won't do it so...uh..."

"Hold that thought, they're starting to stir."

And so they do, both J and N groaning as they start to roll around from their positions on the ground. The female drone is the first to awaken, looking around confused and wary at the unfamiliar location and only seeing the awakening N. She can feel the waves of her heat immediately, grimacing as desire floods her body but like usual, J puts it off of her mind despite the greater intensity. Instead she focuses on the dirt on her suit and fiddles with the large collar placed on her, distracting her even from her missing appendage.

N on the other hand, immediately rolls around in discomfort. His heat has never felt good to endure, leaving him with a hard and painful boner hidden under his long coat. His rolls to his side and holds his hands at the pained body part, trying to suppress the feeling as best he can. But he loses the need to do so as a scent hits his nostrils, an intoxicating and alluring smell.

His eyes darting around frantically, his nose points him at the source, J who is glaring unamused. N gets up on all fours and cautiously approaches, wary knowing what J is typically like with his presence. J's own eyes narrow, not moving as her male packmate comes slowly closer.

Once he gets within a few feet, J gets up on her own all fours and starts to walk around, leaving both murder drones circling each other. N still approaches with a small whine, shuffling awkwardly while J bares her teeth as a warning. But eventually both get close enough.

"Activate the leash."

"Roger that, man."

With a few buttons on the console, both collars activate and suddenly a glowing red chain appears and connects both N and J together. A single leash resembling a metal chain made with a red electric energy, able to shift around the collar instead of remaining in place for flexibility.

J growls at it, surprised by the flash of light that created its appearance and confused as its purpose. N, however, doesn't pay it any mind and instead takes the opportunity to approach J from behind. Smelling more of the intoxicating scent, N pushes his face right into J's sex under her skirt and takes in her smell. This proves to be a mistake as J yelps in surprise, only to become enraged as she turns and smacks N's face away.

He's sent tumbling back before stopping, eyes wide at the surprise attack before glaring at J and growling at her rejection. J hisses, lifting her head up as a sign of dominance as she makes her rage clear. N, while still baring his teeth, takes a cautious step back while J takes a step forward. She gets into a readying position, prepared to pounce on N for his transgression.

Yet the moment she takes a leap, an electric current comes from her collar and shocks her. Within an instant, J's body shuts down and she lands face first to the ground.

David wipes some sweat from his brow, "Phew, glad we stopped that. J was about to maul him."

Jason hummed an answer, keeping his focus on the control console as he made a few commands. The shock J felt wouldn't keep her down long, just long enough for a few actions to take place, namely letting some magnetic force elude from the collar and serve as a minor 'drug' to keep her in a daze when she gets up.

More importantly, it gave the confused N an opportunity. While what just happened was odd, the throbbing in his penis remained his top priority and J's smell never lingered from his mind. With her body inactive, he crawled over back behind her and leaned down to sniff her sex again. Soon this wasn't enough as he gave a cautious lick, coating his tongue with a strange yet addictive taste that soon had him lapping into her vagina. He couldn't help himself but enjoy it, yet his throbbing pain compelled him to take the next step.

Knowing what to do to relieve his pain, he gripped J's hips and began to bring her up by her rear end. He stood on his knees and pulled his cock out in the open, beginning to line it up with J's enticing womanhood. Not paying any mind as the chain connecting both their collars started to shorten to a tight yet adjustable length between both of them.

At that moment is when J started to stir again, feeling N's hands at her hips as she's pulled into position. Her senses come slowly, in a daze from the slow startup and sudden drugged stupor. But despite her confusion, she quickly started to sober up as she felt something poking at her vulnerable and moist entrance.

J quickly made an attempt to crawl away only to choke as the collar on her neck made a sudden tug, stopping her from moving while N was pulled forward by her effort. As he moved a hand to her shoulder to steady himself, N quickly took his chance and pushed right into her entrance. Piercing straight through and, with help from the juices leaking out of her pussy, there was practically no resistance as N's hard member slipped all the way to his hilt. Shocked at his forceful entrance, J cried out with widened eyes as N moaned with a dazed expression.

With his cock tightly hugged by J's walls, wrapping around him like a warm cocoon, he let the moment sink in as he finally is able to mate after so many years of discontent. His cock twitched with anticipation, ready to begin breeding. N's unwitting female partner was frozen, staring into space as she attempts to mentally process what just happened.

With both staying in place, Jason turned to David and ordered, "Decrease the chain again, keep them in close contact."

With a few button prompts, the red chain started to become shorter again, adjusting to just perfectly match the current distance between the mating pair's collars. Now it was barely a foot long.

At this point, N has had enough patience and quickly took to bucking his hips wildly. J yelped, pawing at the ground in an attempt to stable herself while N aggressively fucked her with enough power to sway her body. His movements are reckless and fast almost like a dog rapidly humping. If it weren't for N being so deep in her, he'd threaten to accidentally exit and miss reentry.

With J not going anywhere despite his forceful haste, N decided to somewhat control himself and pause. Seemingly taking a breath, J breathed heavily and tried to compose herself only for N to push her face to the ground. She growled and tried to get up, but quick pump of N's hips forced her to flinch. Taking the opportunity, N shifted his hand at J's hip to grip the ground instead and moved his other hand down to grip her forearm.

Now in a much more dominant position, N began to pound into J again with full speed. His new position keeps his body much more anchored as his cock can now pierce straight through J's womanhood and bottom out as deep as he can go. J moans loudly, feeling N's rapid thrusts reach all the way to her core. While she'd always been able to resist her heat cycles, mating made the feeling so much more intense as her body feels electrified, pain and pleasure surging inside as her instincts start to take over. As much as she wanted to keep her position of power, being dominated so thoroughly and aggressively was having a bigger impact on her animalistic mind than anticipated.

Fairly soon, J's body responds on its own and accepts her situation, arching her back in a way that makes it easier for N to buck even deeper into her. She willingly raises her rear higher, moaning louder when her mate's hips slam against her cheeks audibly. N responds with enthusiasm as he increased his pace and thrust with even greater force.

Watching on with some embarrassment, David commented, "Looks like J's finally more willing to get into it."

Beside him, Jason nodded and smirked, "N's always been the runt of the pack, so looks like a little domination was needed to accept him as a partner. A little sexual manipulation doesn't hurt either, maybe next time it won't be this difficult."

Back with the pair of murder drones, it became clear their passionate union is coming to an end. N's eyes are shut and his body is tensed, tightening as his movements grow more focused yet more intense. J looks in a daze, tongue rolled out and openly moaning as her self control has faded. With some drool leaking out of his mouth, N grits his teeth and gives a few more powerful thrusts before driving himself as deep into J as possible and finally climaxing.

Both drones felt their bodies lock in place, paralyzed by the intensity of their orgasm. Semen pumped into J, filling her up with N's warm seed as she finished at the same time. Load after load shot into her, forced to stay and endure it within N's dominant position.

Jason leaned back in his chair, "And that's that, J should be properly bred now."

David glanced at his coworker, "So what now?"

He responded, "They'll separate soon, mating tends to tire them out after one go. I'm not sure if J will retaliate once separated, so get ready to intercept if need be. Prepare to widen their chain."

Before either could do anything, both men stop at the sound of more moaning. Looking back at the screen, N had begun thrusting heavily into J again, as if he didn't just ejaculate enough semen in one go to impregnate her. With feral energy, his arms are wrapped around J's torso as he pounds with his hips until N cries out with yet another ejaculation inside J.

They stay in place as N finishes for a second time, cum starting to leak to the ground as J's womanhood starts to overflow. Weakly, J starts to try to claw away only for N to pull her back with a growl, barring his teeth as he once again begins thrusting with renewed energy.

Both men watch on as David comments, "I guess N was really damn pent up, fuck."

"Hmmm, let's not interfere then. Usually mating ends quickly so we don't know what'll happen if we try to separate them."

"Well how long does this mating season thing last?"

Jason watches on as N climaxes once again, not even giving J a moment's breath before starting up for a fourth time, "About a week."

Days later, David yawns as he heads into the work station. With a cup of expresso in his hand, he walks through the facility until he makes it to where he's been forced to stay for a while, the monitoring room. After the brazen display of animalistic sex he'd been force to help initiate, David took some days off and yet here he was again.

As soon as he steps inside, his ears pick up the now familiar sound of moaning and bumping artificial flesh and metal. "Fucking hell, they're still going at it?" As David sits down beside a bored looking Jason, he looks at the monitors to see the now also familiar sight of N fucking J.

The pigtail female looked exhausted at this point, eyes glazed and staring into space. N is behind her, still full of vigor as he rapidly keeps his thrusts going, has one of her thighs in his elbow so that her legs are spread and easy to keep penetrating into. At this point J's clothes had been torn, skirt thrown away with her jacket and yellow shirt open to reveal her bare breasts. The collar still remained, it's small red chain keeping both feral machines linked.

As both moaned out with another climax on the monitor, N's seed pumping inside J, Jason turned to his co-worker, "Yep. Almost been a week and the guy's been eager to keep on mating. The collar does keep J in place and doped up so she hasn't got much room to really fight back, especially after already being taken as his mate. I could stop it but N's always been bullied around so I think he's earned some relief."

A small alert popped up on the feed, signaling that it was feeding time for the murder drones. Jason sent David a smirk as he pressed a few buttons, "Check this out."

Within the cage, a glop of metal and oil was dispensed onto the ground, steam rolling off it to signify its heat. The red chain vanished, leaving N and J room to separate without hindrance. J, still drugged up from her collar, stumbled a bit as she crawled towards the meal only for N to jump in front of her.

J growled and arched her back, attempted to look intimidating but N didn't budge as he responded in kind, raising his head up and letting out his wings for extra display. After a few tense moments, J scoffed and crawled away. This left N free to turn and eat.

David raised an eyebrow, "Well...that's new."

"He's the alpha now," Jason noted, "J's already lost her position of power the moment she let herself submit when they mated, she can't take it back now. Even when we undrug her, N's in charge now and already that instinct is making him more dominant."

After N consumed a good portion of the meal, he began shoveling more food into his mouth. David looked disgusted, "The hell is he doing?"

Jason answered as they observed, "Another dominance display. As a sign of affection, some alpha drones help feed their mate."

They witnessed N, after taking as much as he can, turn and head towards J. She seemingly was looking for exit points, looking up at the ceiling for any signs of weakness. In her distraction, N suddenly leapt on her and pinned J to the ground. She struggled for a bit, failing to push N off before groaning in annoyance and glared up at him. N gives a small smile, cheeks slightly bloated with food.

With a small hiss, J turns her head in defiance. With a small roll of his eyes, N still smiles as he lines himself up and thrusts his entire cock into J without looking. Her eyes widen as she gasps at his sudden entry, giving him opportunity to lean down and capture her lips. N pushes his tongue into J's mouth as he feeds her, giving only small muffled protests. Oil slushes between their mouths while N makes his tongue dance with J's to keep connected.

Soon she begins to swallow it down, bit by bit until N pulls back. Their lips separate as their tongues hang in the air, leaky trails of oil and saliva still loosely connected as they give heavy breaths. N slowly leans down and places his tongue on J's neck, making her wince as he slowly licks downward towards the valley of her breasts, leaving a trail of saliva as he takes in her taste and scent. Placing his head between her mounds, N nuzzles himself and wraps his arms around J's torso to begin bucking his hips.

At this point, J just keeps her eyes to the ceiling as she sees stars, lightly moaning as her partner dominates her. Try as she might to keep some semblance of her alpha status, the fuzziness in her head and the endless pleasure her body's endured overpower her rational thought. N wasn't a lowly runt anymore, with some pounding hips he'd become an alluring male.

She hugs N's head into her breasts and wraps her legs around him to push him deeper insider her needy entrance, something not unnoticed by N who takes note of her submission. He pulls his head up and starts to nuzzle J's neck, purring in content. He locks his teeth onto her shoulder, making J groan as N bites, using that to staple himself as he goes back to thrusting. This time with J holding on and willingly mating with him.

From then, J would go on to be thoroughly bred and sire a litter of N's children. A future she accepts now as he cums in her, both moaning loudly.
