Let me see if I have this straight: several of you here are worried that porno fantasy mind control, a thing that has no real-world counterpart because mind control isn't real, takes away the capacity to consent from fictional characters who in no way exist or have thoughts or feelings and whose sole function is to star in a porn game. A porn game that the player, the only real person involved other than the dev, consented to play after (very likely) explicitly acknowledging that said porn game wasn't real and the characters were fictional and that the events depicted did not happen in real life via a warning screen prior to loading the game.
No, I don't find it icky. And I'd like to think that if I did, I'd find it icky in a 'that's not a kink I have' way rather than imputing real-world agency and real-world victimhood to a ren'py script and some images/animations/sounds in a porn game as though they were people.
Fetishes are just stuff that makes you horny. They aren't revealing of your character, they don't mark you as bad or good people, you can't have the 'wrong' fetishes, and you couldn't on-purpose cure them even if you wanted to. Nonetheless, if you find that your tastes change over time, then probably shift your porn selections to suit your evolving palate. No longer enjoying mind control porno for whatever reason? No problem! There's lots of other porn out there. Newly enjoying mind control porn? Have fun! There's lots of great stuff out there!
