As mentioned, I've been playing a lot of Stardew Valley. Got gay married to my sweetie Abigail, because how could I resist a purple-haired proto-goth who loves pumpkins, autumn, cemetaries, and rainy days? I couldn't, that's how.
Also, purple is her natural hair color (the game is set in a universe with both trains and soda pop but also with dwarves and wizards), and let me just say: purple pubes. Oh. My. God. I would kill to rub my face in those.
So she's mine now and we are happy down on the farm.
Meanwhile, there's an entity in the game known as the Joja corporation, a faceless corporate behemoth that seeks to crush any independent commerce and force everyone to shop and work at their soulless identical stores and/or numbing corporate offices. The local Joja-mart manager even has devil eyes, that's how bad they are.
The combination of these two items - my loverly Abigail and the malevolent Joja Corp - recently smeared together into a rather hot fantasy.
It starts with coming home to find Abigail in some skin-tight shiny latex getup - think the outfit of the lead singer from The Pretty Reckless in their Going to Hell video - with cut-outs for the breasts and crotch, acting all submissive and enticing ("I got this to please you.")
She starts sliding further into sex-kitten over the next indeterminate period of time, discovering that she likes being naughty and objectified.
Then come the breast implants; she gets them as a surprise, and loves having them, they're so plastic and unreal.
She got them, of course, from Joja, which is more or less the only game in town for that sort of thing. And now her slide into becoming more and more designed for sex starts becoming tinted Joja; the idea of being a sex object and being a faceless corporate cog - no, corporate asset - blend together in her fantasies.
She begins going off to 'workshops' offered by a particular branch of the Joja corporation. In theory they are about skills and etiquette and such, but of course they are really a sort of corporate indoctrination, deepening her (and the other participants') desire to become Joja assets. Joja property.
Then comes the tattoo, the Joja logo on her shoulder, prominently displayed when she is wearing her tight Joja-blue latex lingerie. She takes a job at the local Joja mart; during which time she wears headphones that pump Joja subliminals into her mind as she smiles and vapidly rings up the customers.
Her salary is put into the Joja bank. It is immediately loaned back to Joja corporation at zero percent interest.
The next tattoo is on the nape of her neck. It's a Joja bar code.
When scanned, it reads 'plastic appliance'.
Now she's listening to the headphones while she sleeps. During sex, she refers to herself as a 'plastic appliance', as 'Joja property'.
The next time she's in the city, she visits the Joja surgeons again.
For the brain implant.
The headphones are unnecessary now. And her personality has changed; she's no longer playing at being a Joja puppet because it turns her on. It's more natural now; she simply thinks of herself as a Joja plastic appliance, a servile sex device which obeys because that's its purpose. She still answers to 'Abigail', but that's because Abigail is a Joja plastic appliance.
She sleeps standing upright now, in a barometric chamber, which Joja installed in the house. It wirelessly connects with her brain implant to guide her through her day; at night she sleeps within it, eyelids fluttering as it bombards her unresisting mind.
She has a new focus now: dissolving her personality.
She is a Joja Plastic Appliance. It says so on her neck. And there is a standard personality implant for Joja Plastic Appliances. Her last desire as Abigail is to melt away 'Abigail' so that she can become a pure servile device. So that she can become Joja Plastic Appliance #19,201 (the number that was tattooed on months ago), with the latest Joja Slavebot Personality installed and running her mind.
So that's the fantasy that cropped up there. I haven't worked out what the protagonist is doing during all this. Are they complicit? Appalled yet unable to do anything? I'd like to find some middle ground allowing for Abigail's complete submersion into the timeline above but that doesn't have the narrator as the driver - but I can't think of one offhand that doesn't instead leave them looking foolish or helpless.
Perhaps I will think of something. Taking suggestions!
