Trials in Tainted Space: Buttslutinator Part 2

Your heart flutters at the mere suggestion of mounting this insane device a second time, but your pucker clenches. You didn’t come out any worse for the wear after the first time - sure, your butt’s a little bigger and a little more sensitive. Maybe you picked up a bit of a fetish or whatever, but it didn’t turn you into some simpering slut who’ll bend over at the hint of a hard dick. This is just a quick, fun break before you get back to exploring the galaxy.

Climbing back onto the strange, ass-obsessed machine’s ‘A’-shaped frame, you grin and place your hands on the joysticks. You know they don’t control anything of consequence, simply existing to give you something to hold and squeeze while the lewd frame does its magic work. Restraints snap around your limbs, and the monitor rises up once more. This time, you get a look at the start-up screen:

Oh. Oh fuck. This might have been a bad idea after all, but it’s too late to change your mind. The bindings have closed over your arms and legs, and no force short of a plasma cutter is going to get you out of them. You don’t bother to struggle, instead listening to the sound of your heart hammering in your ears. It isn’t panic that makes it race so: it’s arousal. Much as you may want to deny it, you’re getting a perverse thrill from being this machine’s plaything once more, bound and helpless, subject to its ass-eroticizing programming once more.

The sharp pinch of a needle poking into your giant posterior jolts you from your reverie. Flushing hotly, you become shamefully, achingly aware of how ludicrously wet you’ve grown in such a short time. Your virginal pussy is like a swamp, beyond damp and sordid with their own needy leakage.

There’s a salty, mediciny taste in the back of your throat that you didn’t notice the first time you did this. Weird how injections can do that. Your jiggling expanse of ass is practically glowing with foreign warmth. Either the ‘nerve enhancement’ you got is making you more aware of the chemicals it’s pumping into you, or it’s putting a lot more of them into your body this time. It’s like there’s spiderwebs of warmth spreading out just under the skin of your ass, tingling and pulsing, making your heart flutter and your asshole quiver. You can feel the inner walls rubbing against one another, shooting flashes of pleasant sensation up your spine until you’re trying to arch your back and gasp in delight.

The screen clicks over to the pornographic feed, and you’re amazed by the resolution. The image appears almost holographic, like those bouncing asses and throbbing, butt-hungry phalli are projected directly into your retinas. There’s some kind of interference though, pulsing through the feed, making the image brighten and flicker to a rhythm you just can’t place. You can’t see your eyes dilating, but you can feel it. The room seems almost too bright, but the dusky cuties’ booties make it easy to tune out everything else. You feel your sphincter loosen in anticipation, relaxing until your asshole is hanging open in between clenches, delirious and ready to be taken.

Emerging from a secret compartment in the ‘Buttslutinator,’ a dildo rises up behind you. You can hear the servos whirring as it’s brought up. Drool puddles below your limp tongue which even now hangs from your open mouth in lewd anticipation. You push your copious ass-flesh back as far as you can, maybe a centimeter at most, and hope the dildo will thrust inside, hope it will split you open once more and fill the hollowness within you.

You can see now why the girls on the screen look so wanton, so submissive. Being empty and unfucked is absolute torture. Why would you look plain and unappealing when you could slut yourself to the nines? When your ass is wrapped up in tight lycra, you can rub it back against a bulging boy’s crotch and tease him into putting it inside. Your eyes start to roll back at the blissful thoughts but dart back to the screen before it can slide out of view. The images are simply too captivating to ignore, even as you imagine hands on your ass, digging into your plush cheeks while you’re fucked over a table.

The dildo slides in perfectly, like your ass was tailor made to sheath the lovely, ever-turgid member. Even though it feels bigger than the one you took last time, accepting it is no problem. A note of pride wells up in you at the realization that you’re a better buttslut than you used to be, that your ass is more fuckable than ever before. You bet the hung stud you’ve imagined for the past few moments would have no problems squeezing on in. Once he bottoms out, he could slap your callipygean cheeks and make them clap together around his sheath.

You moan, and the dildo slides in and out, strumming nerves that have been chemically primed for pleasure. You can still feel the needles lodged in your bum, pumping more of that mystery cocktail inside. That’s probably why you’ve gotten so sensitive back there, and why every stroke of the silicone shaft through your simmering sphincter feels like a miniature orgasm all it’s own. You swear the sensations get stronger moment by moment, making rational thought near impossible, making your curvy hips wiggle and your legs kick.

The girls on the screen are still going at it, mewling and moaning much like you yourself. You feel a certain kinship to them, a bond of ecstasy that transcends mere mortal bounds. They’re getting to be fucked by big, warm cocks while all you have is a measly machine. Your lusty bottom deserves... no, it needs more. It needs to feel a swollen, New Texan horse-cock plowing it wide open while a knotty ausar squeezes in alongside, stretching you wider than any of those screen-girls. You could have that, you realize, if you slutted it up enough. Maybe you could find some panties with a target on the back - and a gap in the center of it.

Squelching loudly, the dildo fucks you faster and faster, knocking the breath from your lungs and the sense from your head. Words flicker in the periphery of the screen in between flashes of ass and dicks:

Flash! Needy buttslut.

A triple-dicked laquine is onscreen, squirting into three different booties, all smaller than yours, while a kaithrit nuzzles lovingly into her spasming backdoor. Tongue slides in...

Flash! Need fucked.

Two ausar bouncing on a pair of rahn ovipositors, their luscious heinies wobbling and shaking as the eggs flow in...

Flash! An empty ass is a naughty ass. Obey.

A kuitan does a handstand while a gryvain pours cum through a funnel into the furry bitch’s wide-stretched pucker.

Pictures and words flash across your glassy eyes, inexorably drawing you toward orgasm, teaching you to love your ass almost as much as you love the things that can fill it. Cocks are the best choice, but in a pinch a bellyful of cum might do. And when all else fails, you can buy a transparent anal plug so that when you bend over, you can show the whole world just how ready to be fucked from behind you are.

White goo dribbles to the floor, hanging from your quivering cuntlips in a curtain of licentious lubricant. You’re grateful for the built-in lube dispenser. The next partner in line could wet his dick in the feminine flow and be ready to bust in your back-door the moment your previous lover pulls free - but not before giving you a healthy glaze, of course. Less lucky buttsluts would be happy to have you around. You imagine yourself lined up next to a bunch of panting shemales, letting dozens of big bulls slick their tools in your drippings before violating the squirting, infinitely femmy former-boys.

The number of asses onscreen double, not because more of your sister-sluts are getting plowed but because you can’t keep your eyes from crossing. You can’t keep yourself from moaning or talking dirty either. Words spill out of your lips entirely on their own, begging the machine to fuck you harder, demanding it turn you into sluttiest cum-dump this side of the milky way. You won’t be happy until there’s enough spunk in your ass for it to be the true ‘milky way’ and the galaxy is seen as a pale imitation.

Cummy, slippery thoughts won’t stop sliding through your climaxing brain, and you don’t want them to. You love it here, clenching and orgasming, feeling your ass slowly continuing to expand, transforming into an anal-fetishists wet dream. With each wave of pleasure, you feel less aware yet increasingly happy, delirious even. The dildo pops out, but you keep cumming, not from pleasant interior soreness but from the sense of your skin stretching out over an increasingly swollen ass. It’s tight and yet still jiggly. Whenever the pleasure becomes too much, your muscles pulse and squeeze in tandem, twerking the cheeks one after another.

It’s almost too much to endure, being this sexy, this fuckable. Even when you’re drooling and over-fucked, your body looks like it’s begging for more. The corners of your wide-open mouth quirk upward as your conscious mind is shut off, orgasm by orgasm, exposing your bare subconscious to the flashing images and words, allowing the wanton video to further etch itself in your mind. A larger dildo swings up, the perfect match to your larger backside, and you shut down completely, panting like an animal.


You come to on the floor next to the machine, propped on an ass almost too thick and juicy to be believed. Glowing with approval, you stagger up and collect your things. You don’t even rightly remember taking them off, truly.

Could you complete your journey bottomless? Surely such an enticing booty would be irresistible to this galaxy’s biggest, strongest dicks. Why, you wouldn’t even need to walk anymore! You could just find yourself a hulking brute to fuck your ass for the rest of your journey, carrying you around on his pole like an ornament.

You glance back at the machine, feeling suddenly hollow, deeply so. If you climbed back in, you wouldn’t have to find someone to fuck. Is a little mental reprogramming too steep a price to pay for endless anal pleasure?

Whatever the case, you’re definitely a buttslut now. Your doubt you’ll ever be able to have a small ass again, let alone go unfucked for more than a few days.
