Melanie had never been sure about this whole 'vore' thing. She'd always made an effort to steer clear of preds and avoid the subject when possible. In her new college, though, it was a huge part of the culture.
"Pred or prey quiz! Click here to find out what you really are!" the link reads. Hesitantly, the arctic fox clicks it.
She enters "Melanie" into the box for a name and proceeds to the first question.
"How many meals do you eat per day?" it reads, with options ranging from 0 to "9 or more".
Taking the quiz hadn't been Melanie's idea, of course. She was as uncomfortable as ever with the whole ordeal. Her friends, though, insisted they knew. 
Most of her group considered themselves prey; a couple thought themselves preds to her dismay. None had actually eaten anyone, though, and of course she didn't need to ask to know none had been eaten. It surely wasn't that serious.
When she'd said she hadn't really thought about it, they told her to take an online quiz for it, and now here she is.
She answers the 15th, final question, and the results screen appears.
"You are: PREY!"
Her heart pangs with anxiety as she begins to read the short description under the result, unsure if she should even share this with her friends or just say she forgot to take the quiz.
"You exist only to be eaten. Your role in life is on the lower end of the food chain, and there are hungry preds out there who'd love to devour you-"
Just as she finishes the first paragraph, the screen bugs out. The text becomes a jumble of random characters, and the background flashes between the usual white one with the website's logo and pure black.
A textbox appears on screen as her web browser stops responding. "ERROR," it reads, "You look delicious."
Melanie sits back in her chair as she reads the message, her fur standing up in fear and her face contorting into a confused grimace.
Someone appears on the screen, an anthro cheetah with white coloration and a spattering of spots and strips that slowly oscillate between colors. The figure appears to be comprised of smooth metal plating with visible grooves between plates.
"Hello, Melanie!" the figure says in a somewhat choppy, monotone voice, "It looks like you're trying to find your place in the food chain. Would you like help with that?" The figure appears to lean forward with a pair of rectangle glasses appearing on its face. As it speaks, a speech bubble appears beside it. Options labeled "Yes" and "No" appear under its speech.
Melanie nervously clicks "No".
The cheetah tosses aside the glasses and laughs as the speech bubble disappears, "Did you think I was actually giving you a choice?"
It gets larger as it appears to approach the screen. It opens its maw wide, revealing an inside comprised of a smooth, black lining with the outlines of metal tubing visible just beneath the surface. A long, prehensile metal tongue lulls out of the mouth, and the figure points towards its mechanical esophagus.
"Liking the looks of where you're going, meat creature?" it asks.
Melanie, her heart racing, maneuvers her mouse to the start menu and tries to shut down the computer, but the figure grabs the cursor and bites it in two. It chews both halves and swallows them, a bulge sliding down the parts of its neck visible between the metal plates of its body.
GULP
Melanie lets out a small squeak in terror and pulls her legs up in her chair, staring at the screen over her knees in fear.
"Alright, enough playing around, c'mere~" the figure reaches one clawed metal hand towards the screen, and it moves right through it, as if surpassing an invisible barrier.
It grabs Melanie by the arm, wrenching it away from where it's tightly wrapped around her legs, and it pushes its head through the screen to stuff her arm into its maw.
ULP SLLLK
Melanie lets out a high-pitched scream that's cut short as the digital pred's second hand reaches behind her head and stuffs it into its maw. The screen of her laptop bends outward to accommodate the commotion going on between the digital world and the physical. The rest of Melanie soon follows her head into the maw as the mechanical figure pulls her into itself with a ravenous hunger.
GULP ULP HOOOUUUURRRRP
The cheetah lets out a loud belch and disappears back into the screen then takes a pace back to admire itself. The metal plating over its gut has opened up to make room for the enormous pouch of elastic black material that comprises its stomach. Metal tubes and wiring cover most of the surface of the pouch.
GLRRRRGGGGLLLE GROOOOAAAANNNN
The figure smacks its gut, causing Melanie to squirm in discomfort inside, then floats up to the top right of the screen and taps the X on the frozen browser window to close it. "Now let's have a look at your desktop, shall we?"
Inside, the fox girl writhes as she tries to struggle. The interior of the stomach is extremely slick, and she can't get any grip on the inner surface of it, only able to slide around into different positions nestled into the bottom of the artificial gut.
Loud gurgles and groans surround her, though they sound like they're coming through a cheap speaker, and mechanical whirrs and hissings constantly surround her.
GGGRRRRRRRGGGLEEE GLORP
A strange fluid is pumped into the stomach through a couple of valve openings near the top. It rises until it's up to Melanie's shoulders, and she squirms harder in fear of what's happening. Her squirms cause some of it to splash over her head.
Heedless of her struggles, Melanie can hear the pred rummaging through her desktop as it picks apart her files outside. "Homework? Wow, this is double the minimum word count! You must've put a lot of effort into this, like some kind of nerd."
RIIIIIIIIIIIIIIIIIP
Melanie notices that her fur and hair is separating from her body, floating in the fluid surrounding her and slowly dissolving. Her skin starts to burn, and it burns a lot more when she moves. She curls up tightly.
"Oh here we go, then fun part where I get to feel your flesh burning away~ It always feels good to melt you squishy meat things~"
GLRRRGGGLE SLOSH CHUUUURNNN
Melanie whimpers and sobs as the layers of her skin are burned away. Her blood starts to mingle with the acid surrounding her.
"I could use a nice place to lounge while you gurgle up in there. Hold on a second, don't let chunks of your flesh start sloughing off until I've found something; that's my favorite part, and I want to enjoy it." 
The pred makes its way down to her task bar and briefly deliberates between the applications present before opening Minecraft. It loads up the survival world she shares with her friends and plops onto the blocky bed in her home.
"Two beds next to each other? Were you the romantic type or just trying to have a fancier place to sleep?" the cheetah asks as Melanie is violently tossed around inside by the pred's shift in position. She can't feel her hands or feet. "Either way, makes for a very nice place to lounge, so thank you~"
The digital pred relaxes and runs a metallic hand over the mess of tubes and wires surrounding its bloated gut, "I want you to know that I don't feel sensations the way you do. I can 'feel' every byte of data in your machine like a part of my body, and that includes you now. The chunk of flesh slowly dropping off of your arm as it melts? I can feel that in detail you couldn't comprehend, and it feels very, very good to destroy you~"
GRRRRRRRRRRGGGGLE
Melanie fights for consciousness inside the digital being as it churns her away, and it only rubs over her and relaxes.
"Goodbye, Melanie~ And don't worry about your friends, I'll make sure they get to see what happened to you~"
The pred relaxes as Melanie fades away completely. It continues to relax as every little bit of her is processed by its body. It doesn't need sustenance, of course, nor does it have any use for it, so all of Melanie is turned into waste.
After a while of her computer running idle while the pred processes her, it finally gets up off of her bed and waltzes out of the window Minecraft is running in. The pred heads back to her desktop and makes its way to the recycle bin.
"Time to get rid of you~ Thanks for dying in me, turd mound~"
The pred perches on top of the recycle bin and lets loose what's left of Melanie into it.
PFFFFFF SPLBLRLRRLLTTLRTLRLTLRLLR
A liquid slurry of bones and a rough approximation of scat that's black in coloration is forced out the pred's backside into the bin, which bulges out with the mess of junk data forced into it. All that's left of Melanie piles up inside in a filthy heap.
"Whew, that felt good~ Now to wipe..." the pred grabs a folder labeled 'Friends and Family'.
It grabs each photo out from the folder and wipes some of Melanie's remains off the metal plates of its rear onto it only once before tossing it into the bin below and reaching for the next, being as inefficient as possible in an attempt to go through as many of her beloved memories as it can.
When its metal ass is sufficiently shiny and devoid of any remaining smears of Melanie, the pred looks inside the folder and notices a couple photos left. It hops off the bin and opens the folder up over it to dump them in regardless before smacking its hands together as if dusting them off.
"There's another meaty preything down, onto the next~" and with that, the cheetah disappears back into the internet of things to find its next victim.

The group chat for Melanie's friend group receives a message from her device. It contains the message "hey here's what happened to your friend. she was prey btw" and an attached file titled "melanie.jpg" displaying a heaping mound of shit, bones, and ruined family photos filling up a recycle bin.
A strange, robotic-looking figure waves at  them with a smile from the message box before hopping off it down off-screen and disappearing.
