    "Reeeaaauukk!!"
    A horrible scream echoes through the dilapidated ship, far beneath your position stalks a Juggernaut. You had been tasked with sabotaging an infested hive, but one firefight with some infested had gone on too long. And soon enough a Juggernaut had come barreling into the room, making an already desperate fight even worse. Now you lay hidden in a small alcove, your frame struggling to knit its cuts together as you watch the infested below hunt for any sign of your presence. The thought of picking them off from up here does seem pleasing, but the idea was squashed as you saw Mutalist MOAs wander into the room, followed by a pair of Osprey. Nestled into a corner you just have to ignore the tendrils of nearby infestation licking at your wounds, their corrupt nature trying to get a hold on you. Focusing back onto the room you notice the Juggernaut heading towards an exit, picking up speed as well. The abomination no doubt having detected another intruder who's being much more active than you are right now. Still, you're thankful for the good fortune, the rest of the infested milling about in the room soon marching off to join the nearby battle.
    Quickly, you leap from your hiding spot, landing on some nearby shipping crates. The area seems clear enough to allow you to finish the job and quickly extract, you would have loved to do this while cloaked but a leech eximus had denied you of that. But as you move to disembark from your vantage point a pained groan echoes through the room, the sound of metal collapsing under its own weight. Normally you could have leapt away but with the damage already done to your frame all you could do is let your standing point crumble away and send you sprawling to the floor. Lying on the ground you find yourself thankful to some object that cushioned your fall, but as you try to pull yourself up you realize what you landed on, a Mutalist MOA that hadn't left the room yet.
    The infested mess of machinery and flesh winds a tendril around your waist, keeping you locked to it. Quickly you reach for your dagger only to find it missing thanks to the fall you just had, making you resort to grabbing at the tentacle keeping you stuck to the MOA. Its only now you realize what the infested you were rubbing up against earlier was doing, the grimy tentacles from the MOA beginning to merge with the flesh of your frame. In your frame's weakened state the infestation had been softening it, making it malleable to whatever changes the infestation desires. Jolts of pleasure, pain, and numbness run throughout your body as the MOA tries to hijack your nervous system. It takes all you have to block out the compulsive orders of the hivemind trying to shove its way into your head as the MOA continues to merge itself with your lower body. Struggling against the MOA you kick your legs, trying to squirm out from its grasp only to notice two new appendages kicking as well, the abomination having succeeded in linking your motor skills to its own legs. Terror begins to set in as you realize you're losing this fight for your own body, the influences coming from the infestation growing stronger as well. Desperate you decide to stop resisting against whats happening to you physically and you focus on keeping the hivemind out, to retain control over your own thoughts, and miraculously enough it begins to work.
    While your mind is preoccupied with retaining control over your form, the MOA continues to morph you, sealing its body snug up against your own. But as you regain ground against the infestation the MOA begins to get affected by you, its own body beginning to shift and match the armor of your frame, the sacks of tar disappearing in favor of armor plating. Soon the MOA's form is inseparable from your own lower body, the coloration being an exact match. But the changes don't end there, as your own legs shift to match the styling of your newly granted hind legs, all four of your legs now being thicker than before, but still carrying the marking of an Ivara frame and ending with solid feet. Whatever will the MOA once carried is now entirely gone as you finally defeat the presence in your head, granting you full control over your new form.
    Hesitantly, you take a few steps forward, only to find your control over the body to be as adept as your previous one. The merging of your frame and the MOA's feet had lead to something similar to an early prosthetic, except much more durable and as quiet as your previous footfalls. Normally you'd be terrified but for some reason looking at your new body gives you excitement, filling you with the urge to simply run around and enjoy the changes as a gift. You can't resist the urge, and trail an arm along your side, and only find yourself amazed at how every single inch of your lower body can feel the sensations of your hand. But sliding your hands across your form had an unintended effect, the wide hips almost molding to the shape of your hands when you stop to grip them, a sexual urge beginning to take you.
    Reaching down to your crotch, you're surprised to find nothing there. Your frame usually reveals your pussy as you grow aroused, but your front is entirely bare. However you begin to feel more changes overtaking your body, specifically your wide-once-MOA rear, two plump lips parting at your hindquarters as you feel a puffy anal ring form above them. But instead of them being the holes you're used to, you can feel the remnants of infestation molding them to new forms, the anal ring expanding and puffing up into something that would belong on a large Earth animal and the insides of your pussy shuddering as they stretch out, adding more length to your love canal. Still you can feel the lips growing thicker, the throbbing of your lower lips not stopping as they plump up more and more. Your once tight pair of lips now puffed up to the point where they'd be better fit on an animal that lives solely to breed than your own body. And with that thought, your mind is filled with images of yourself hunkered to the floor, behind raised and offering your glistening slit to whatever male is nearby. The image of a pack of kubrows taking turns with your hole making you shudder and your pussy spasm, imagining their thick shafts plunging in and out of your inhuman holes and filling you with their children.
    Quickly you force the images out of your head, feeling a tinge of disgust at what you were just thinking of. You try to relax and push the arousal out of your mind but it never seems to truly leave, flashes of indecency here and there. It would only make sense to use your new body wouldn't it? With a body so thick and voluptuous it'd be a waste not to drown yourself in pleasure. After all your form is perfect for a breeding tool, a nasty cock hanging between your legs, leaking pre constantly. The Lotus always wanted children, you could give her them, yeah that sounds good. Your comrades would understand if you decided one day to just shove your way inside of them. Your knees grow weak as your imagination runs wild, filling you with scenarios involving you stuffing someone full with your gigantic rod, making them get addicted to your cum as you violate them. Pushing back you mash your hindquarters against a wall, your over-stimulated pussy wetting the wall and letting you grind against it for pleasure as you get lost in these images. The lips of your pussy continue to puff up as you rub against the wall, infested bulbs getting caught on your lips hear and there, building your arousal but also causing another change in your body. Slowly the thick lips of your pussy begin to grow tight together, your clit beginning to elongate as well, but you're blind to the changes as caught up in the pleasure as you are. Soon your clitoris is horribly elongated, your little button almost shooting out in length, more than halfway past your belly. At this point its length is only slowly added onto with a centimeter here and there, instead it the morphing takes the shape of it inflating all around, your clitoris width reaching the circumference of your fist and still growing. Your clit only stops rounding out when its the size of what your thighs used to be, a gigantic shaft of sensitive meat hanging between your legs, something you're still unaware to thanks to the bulbs of infestation getting caught on your anal ring now, the thick flesh constantly teasing you as you grind into it.
    A shudder runs throughout your body as your rubbing along the wall is stopped, a bit of the infestation having managed to firm up but also dig into your hole as you grind into the wall. While you do that, your clitoris continues to change, the end of it bulging out to form a mushroom head of flesh, and closer to the base a ring appears, to complement the sheath beginning to burgeon from the base of your womanhood. Your clit finally finishes its transformation into a nasty mix of man and horsecock, and soon the juices that were leaking from what remains of your pussy begin to leak from the urethra of your new manhood. Speaking of your pussy, you feel an incredible sensation of pleasure, your body shaking, as the ovaries that were once inside of you solidify. The infestation tweaking those egg-factories of yours into a new source of genetic material, two gigantic balls that push their way out, with a sickeningly loud schlick and into a gigantic sack that hangs from your body. The added weight causes you to land even harder onto the infestation reaming out your asshole, which in turn makes the infestation dig deeper into you. It's at this point you realize whats happening to you, but its so late and it feels so good you can hardly bring yourself to care, instead you return to pounding your animalistic anus onto its intruder, making the infestation squirm deeper into your anus. But as that bulge of infestation plumbs your insides, it reaches a certain newly-formed gland, a prostate which grew to compliment your manhood. Coming into direct contact with the infestation, after having just formed, twists it even further. While your body was already thick with the attachment of the MOA to your rear, you can feel yourself growing larger, more mass being added to your form while your upper body keeps its lithe shape. Your anal cavity begins to grow cramped as the bulb inside of you seems to suck at your p-spot, causing it to balloon further and further, speeding up the production of more sexual fluids to fire from your mess of a rod. The muscles of your anus clench around the flesh tickling your insides hard enough that it pops from the wall, and embeds itself inside of you. The mass begins to fully cover your p-spot, the direct infusion of infestation melding with your expanded gland and causing the potency of the gland go into overdrive. Desperate to get off, and relieve your over-filled prostate of the fluids inside it, you begin to slides your gigantic cock against the floor, spraying your pre everywhere and slamming your massive balls against the cold metal. The punishment on your sack only makes you more aroused however, encouraging you to pick up intensity as your endowments makes a mess of the floor. As you heap abuse upon your sack, you feel more and more pleasure from your shaft on the ground, the infestation acting as a great lube for you to rut the ground with.
	Unbeknownst to you, the door to the room opens, a mass of Infestation known as an Ancient sulking its way inside. Its body slowly reforming, making sickening slurps as its form pulls away, pulling you out from your masturbation-induced daze. Sticking from the center of the Ancient is a Saryn frame's rear, her hips are over-inflated, leading into enormous thighs. Your eyes however are stuck to her anus, watching as the Ancient pulls a tentacle from her ass, every few inches along the tentacle is a knot, causing the Saryn's legs to shake as each bulb is pulled from her insides. Quickly you leap from the floor, the infested tentacle in yourself exiting on its own with a thick shlurp, having done its job in hastening your corruption. The ancient shifts away, its malleable flesh changing into a cube-like form for you to step over, the Saryn's gaping anus still revealed to you. The head of your shaft drips pre down onto the Saryn as you stand above her, any worry of lubing her up isn't present in your mind, instead you can only think about shoving it inside. Leaning down you line up your wide head, feeling your slick flesh slide all about the Saryn's cheeks, her own flesh rippling and shivering at the touch of your wet tool.
	Unable to wait any longer you shove forward and are met with zero resistance. Your comrade's anus had been stretched so consistently that your head was almost swallowed by her, the infestation having managed to turn her once tight ass into little more than a gaping maw for cocks, something you cherish now. The hole spasms around you as you push more of your length into her, the poor Saryn clenching to keep you out, unaware that the shaft violating her belongs to a fellow Tenno. But the added tightness only encourages your progress, her anal muscles essentially massaging your cock as you easily slide into her, the Saryn's body being stretched out around your cock. It feels right to fuck someone like this, making their hole swallow your girth, to make their hips widen even further, their legs unable to stand together due to you spreading their hole so wide. Your front legs stand strong as you tense your hind legs before jamming the rest of your cock in. "Ouuhhh!!" Your comms screeches with static and the pained moan of the Saryn, her hole accepting your mass of flesh into her insides even further than before. Pressing deeper in you can feel the sheath of your cock bunching up against her hole, and your warm sweaty balls finally touch flesh, making you grind into the Saryn, spreading your musky sweat all over her.
	From where you are, you have no idea what the Saryn looks like filled with your girth, but you can imagine her afterwards. With a goal in mind you lean down, putting more of your weight on the Saryn and Ancient but also getting your body into position. Slowly at first you ease your cock in and out of her, wetting her insides with the pre from your cock, but that just isn't enough. You can't just fuck her, you have to breed her, the thought of breeding every Tenno taking hold in your mind again, images of mashing your cock into female frames, images of making male frames seat beneath your sack and choking them on your pungent odor, rivulets of your balls' sweat pouring onto them. You can't stop here, you need more. Picking up your pace you shove more and more of your cock into the Saryn, pulling out and slamming your bitch-breaker back inside, the end of each thrust making your mind drunk on pleasure. You exist solely to impregnate others, regardless of who or what they are, finally acknowledging this you can feel changes take your genitals. Your cock beginning to grow again, each thrust from your shaft making it throb larger, forcing the Saryn's body to stretch more and more to fit your corrupted length. And your balls aren't safe from the changes as well, the orbs inside growing larger and larger, the skin of your ballsack growing to contain the colossal cum-factories, their constant process of filling your sack with cum now becoming audible with thick squelching.
	Your balls had finally grown so large every thrust drags them across the floor, but even the added weight can't slow down your need to fuck your cum into the Saryn, your strong legs letting you thrust deeper and deeper inside with your constantly expanding cock. Suddenly the hole you're embedded in begins to twist around your shaft, making your entire length shudder and spray an extra helping of pre-lube inside of your mate. As the twisting stops, the ancient beneath you begins to pull away more of its mass, revealing the tight belly of the Sayrn and her lower body. None of this is noticed by you as you ream into her, but her entire body bulges with your cock, you had grown so long you had managed to reform her entire insides, each thrust of yours sending your shaft up through the Saryn's throat, leaving your head sitting on the back of her tongue. In your lust-induced haze you barely acknowledged the feeling of her hot mouth, save for her tongue which would writhe every time you sheathed your rod into her, her tongue squirming as its pushed down in her mouth and coated with a blast of pre. With only your lower body thrusting into her, your upper hands are free to knead your breasts, with zero care to see them enlarged you instead feel the infestation puffing up your nipples, making your breasts more sensitive as your pinch and tug at your tits. Alternating between pulling and kneading your nipples sends shocks of pleasure throughout you, hardening your cock and making your ballsack throb, a domino effect of ecstasy gripping you. 
	Each thrust of your manhood into the Saryn is soon met with a loud shlick, her form having been coated in a combination of your pre, her juices, and your combined sweat. She will never lose the scent of your musk, ingraining your ownership of her not only inside her hole but on her skin as well. But even then, the wet noises coming from her are far too loud, each of your thrusts making your lower body get sprinkled with liquid. And soon her hole begins to gain tightness, each thrust of your musky length harder to pull back from as a suction sets in. The Saryn's hole seems to come to life as it tries to keep your shaft inside, aggressively tensing around your meat and pulling back on it, and at the end of each thrust you feel something dig into the depths of your sheath, licking at all the sweat that's been caught up in there. 
	Sadly all things must come to an end, and on the horizon you could feel your climax approaching, the pre you shoot into the Saryn becoming thicker and your cockflesh hardening, making her body conform more to its shape. Your ballsack's squelching gets even louder, as your package tightens up, your warm and picked full sack pressing not only against your hips but your cocksock's as well. Thrusting in as hard as you can, you can't help but rear back on your hind legs as you start cumming into the hole beneath you. Your urethra dilates as you explode inside of the Saryn, your cum only arriving in thick globs that shoot off into her mouth before sliding back down into the rest of her body, making her taste every helping of cream you inject. Still the sight is kept from you as you keep the base of your cock snug up against her, sealing the jizz inside of her as you fill her up. What you can do however is feel, feel her belly rapidly expanding with your cum, the seal of your cock in her hole is so tight that you can feel the pressure of your sperm inside her actually lifting you, and even small spurts of come squirt from her mask, her once tightly sealed armor being forced open by your thick nutjuice. The passage of time is a mystery to you as all you can do is writhe in your orgasm, the once hugging hole of the Saryn long gone and replace by an inflated bubble of cum, her walls no longer touching you due to being packed with so much jizz. Clenching your muscles you force out the last batch of sperm, a thick and heavy batch, something the infestation had given you to plug people up, but had only ended up being shot to the front of the Saryn's mouth. Leaving her lips sealed, mouth full of cum, and making it so she cant even suck up the recesses of cum in her helmet, forcing her to smell your pungent payload. Each inch you pull from her brings a slurp with it, her hole greedily holding onto you, trying to keep you inside, but you're far too eager to see the result of your breeding. A loud wet smack sounds out as her hole clenches shut the second you pull out, leaving all of your sperm swimming around inside of her. Taking a few steps back you look down and can barely make out the round sphere of cum as a Tenno, her form so massively stretched with cum she looks like an infested hive. Looking down to see where you penetrated her, a strange site makes you pause, where you'd normally see an anal ring is instead a new mouth having grown from your corrupted length pounding away. The lips contort for a bit, somehow swallowing the cum pushing at them back into the Saryn before panting out, and your comms spark to life, "I-I'm c-can feel a second mouth...? But it's so full of delicious cum..." And as that cum settles inside of her and begins working her anus into a womb for itself, its safe to say she'll soon be the latest addition to the network of hives on the ship.
