	"Zero signs of enemy life, good work Tenno. Now head to the extraction point." 
	Tension leaves your body as life exits the last Corpus in the area, letting you load up your boltos before strapping them to your hips. You had been called out on a standard extermination mission, even if you wanted to stay in your ship and 'experiment' with new weapons, you had to heed the call. Thankfully a comrade had also been called in, a lithe Mag suit that helped shred the shields of the Corpus, and gave you something nice to ogle. "Good work Mag, lets head on back now~." Maybe a bit too nice to look at, even though you had pleasured your ass-pussy before you left, watching the sleek form of your female compatriot in action made something inside of you stir, and you can't help but tease her.
	Even hidden behind her mask, you can see a hint of red on her face, "Y-you shouldn't talk like that. It's inappropriate." She tries to move past you but you're one step ahead, making sure to wiggle your hips as you lead her towards the extraction point, putting on a nice display of your recently widened hips. You can feel her gaze on your assets, something you definitely feel pride in. Every now and then you suddenly stop in front of her, the Mag's gaze locked onto your rear making her bump up against you, and giving you a chance to grind up against her. A familiar itch begins to rear its head inside of you, your anus hungry for something inside of it.
	In the distance you can see the point, you're so close to home and your toys, but at the same time you don't want this Mag to slip out of your grasp. As you both turn a corner you swing your hips, pushing the mag up against a wall. "What the-, Zephyr!?"
	Before she can move away you press your rear end up against her, pushing her back up against the wall, "Don't mind me, j-just gotta work out some tension..." Sliding your ass across her crotch makes you shiver, your soft anus kissing at her pelvis, looking for something to penetrate it but only getting caught on the clit of the Mag's womanhood.
	"What are you doing!? G-get away f-from me...o-oohh!" Her complaints fall on deaf ears as you press down harder onto her lower body, the teasing of her clitoris on your anal ring getting you more and more in the mood. Focusing on her clit you press your anus down even harder, lost in the sensation of her thick clit pressing against you, her flesh throbbing and hardening. And then you feel her clit enter your asshole, her womanhood expanding as your rub your ass-pussy onto it, your mind filling with a mix of lust and guilt as your perverted anus corrupts the Mag.
	"Oh my Mag, I didn't know you were a man. You hide it so well." You can't help but tease her more as you feel her once little clit expand inside of you, the small bump taking on a much more phallic shape now that it's pierced your depths. As you mash yourself up against her, you can feel her pussy leaking onto your cheeks, but her juices seem to stall and soon you feel a part of her body pushing back against you. Your nasty anus pressing up against her pussy causing her hole to close shut, her flesh bunching up in the spot before with a slurp two orbs slip into that mound of flesh, granting the Mag a ballsack.
	The engorged clitoris inside of you begins throbbing harder as mass gets added to it, thickening and stretching your hole wider. "A-ah, wh-what's wrong with you!? Wh-what's wrong with me?..." Uncertainty heavy in the poor Mag's voice as she stops struggling against you riding your rump all across her crotch. Two hands begin to travel down your sides, rubbing your hips and making you shiver in enjoyment as the Mag begins to give in to you. "I-what do I do?" Her hands roam over your expansive cheeks, squeezing you here and there and making you clench around her phallic clitoris, her voice heavy with lust as she manhandles your rear.
	"Simple, you just gotta pump. Me. Up~." With each pause you slam your ass down onto her after barely pulling away, making the Mag groan as your stimulation makes her clit throb. At the final thrust you feel the big change happen, the grotesquely stretched womanhood inside of you suddenly begin to grow as a warm liquid begins to fill your rear cavity, the first shot of jizz inside of your slutty ass-pussy. Slowly the Mag loses the strength in her legs and begins to slide down the wall, you just cant let that delicious cock escape just yet however so you follow her descent, keeping her crotch snug up against your rear end and sitting in her lap as she hits the floor. "C'mon, we aren't done yet."
	Squatting on the floor, the Mag's hands still on your hips, you begin to bounce yourself upon her new cock, making the length throb and shudder while your anal ring clenches around it. As turned on as you are, you're getting virtually zero pleasure from Mag's admittedly small length, each thrust down frustrating you due to how empty you feel inside. "I need more, you have more don't you? Fill this slut up with your thick cum!" Your bouncing grows more fervent as you try to wedge more cock into you, your anus taking the Mag's length to the base.
	"Y-you're s-so tight!!" At the end of one of your thrusts you feel the Mag's grip tighten, and a sudden magnetic force ground you down against her crotch, seating you upon the Mag's balls. More hot protein gets pumped inside of you, shooting deep into your ass and just barely scratching at the itch you feel, but before the teasing relief gets to you, you feel your ring expanding again. Slowly the girth already inside of you grows in length and width, your slutty hole continuing to twist the Mag into a stud as her balls expand with her cock. Soon instead of bouncing down between the Mag's thighs you have a sizable cushioning with the Tenno's package, each time you set down letting you feel the sperm packed away in those still growing balls. "I gotta...I gotta breed you. Gotta make you mine..." Soft murmuring reaches your ears as the length inside of you continues to expand, each hop along the cock coaxing out an added inch of growth. The once small cock now makes a sizable bump in your belly every time you slam down, but its still not enough for you.
	"Grow already! I need more inside me, this isn't enough!" Your frustration setting in again makes you thrust down harder than before, your cheeks rippling as they meet your ballsack cushioning and causing tremors in the soft flesh, making the Mag groan in a mix of ecstasy and discomfort. Your efforts seem to be working as you feel the cock inside you spurt up an extra few inches, making that buzz of pleasure return after having been away from so long, your stomach beginning to bulge out in the shape of cock. "You need to learn your place as my dildo! All you have to do is sit there and get bigger for my asshole!" Chiding the Mag you continue to thrust down upon her cock, each thrust downward causing the cock to jump up inside of you, along with squeezing a small spray of pre from the Mag's package. More and more you begin to scratch that itch inside of your anus for a stretching as the cock you're riding along plumps up more and more, not content to simply grow in length. Looking down you see a satisfying bulge of solid manmeat pressing out from your belly, the head of the cock right below your chest. Stroking at the bulge you start to grind down against the base of the Mag, who can do little more than moan from the added pleasure of your hands upon her cock, making her length slowly push upwards, until the head of her cockbulge is between your plentiful breasts. Letting go of the bulge you instead grab your great pillows and begin mashing them against the bump between them, holding them together you begin to bounce up and down again, giving a titjob to the cock inside of you. "Wh-who's the real slut here? Me or you?!" 
	Picking up your pace you slam more and more of the cock into you, the head's path upwards ending as the cock inside you begins to widen out instead, stretching your tightest areas to make room. You can feel every spurt of pre from the cock using you like a living condom, each blast of the liquid no doubt shooting high enough to land in your stomach, not that you can tell with the buzzing pleasure in your mind. Bouncing against the cock becomes harder over time however, as the package that doubles as your seat becomes more packed with cum dying to be let out. "Y-yeah! P-pump me up you slut!!" Just as you say that the Mag's hands grip you again and you feel an intense force press you down.
	"Take my cum you whore!" The Mag screams back at you as her cock erupts deep into you, her magnetic powers holding you down tight enough to create a seal. Her gigantic mass of cockflesh throbs inside of you, widening to make room for all the sperm shooting out of her overstuffed ballsack. Your body struggles to contain all of her fluids, your belly ballooning out along with your bellybutton, and it feels like even your breasts have started to fill with the Mag's cum. Barely you manage to choke down some cum threatening to come up through your throat, but just as you manage to swallow it, it comes back up even stronger thanks to another throb from the Mag's cock. The inside of your helmet is filled with cum is it leaks from your mouth and nose, the fact your armor is sealed leaving the cum with nowhere to go, instead settling down and marking you with its stench. It feels like hours, maybe even days, as you're utterly filled with jizz until finally the payload stops. The itch inside of your ass is gone, wiped out by the firm packing you got, and the Mag's powers still hold your widely-stretched anus against the base of her mammoth cock. You feel a soft shifting of the fluids packed inside of you, but it barely registers to your cum-drunk brain, no doubt filled up with cum like the rest of you. Held snug up against the Mag's cock, she proceeds to walk to the extraction point, keeping your bloated unconscious form on her cock. "Now where was it?"
