Your boring job and your boring life are only interrupted by the occasional weekends with a prostitute that has become your friend beyond her profession. You use her services regularly, when she decides to change things up. And things certainly start changing.

Choker Change is a basic MtF transformation game from the perspective of the victim. The protagonist is addressed as "you" and lives through many different TF themes you can influence. In this interactive story, you'll be the victim 99% of the time. Don't expect to come out more dominant than you came in. If you want something like that, Choker Change is probably not for you. If you enjoy submissive, slow, forced transformation with terrible odds of resistance, come a little closer.

While transformation itself is inevitable, you can impact how strong you are changed and can decide if you don't want some things changed. You want to keep your dick and stay a shemale? That's absolutely possible. You don't like the big tits the game endowed you with? Well, you'll have to carry them for a while, but there'll be a chance to get a breast reduction. Your character is not perfectly mouldable as this is not an alter ego creator, but there are plenty of chances to influence the specifics of your transformation.

Will you succumb to femininity? Or will you come out ahead and eventually turn the tables on your captors?

The most prevalent transformation themes are male-to-female transformation, male-to-shemale transformation, slow transformation, forced/involuntary transformation, mental changes & mind control, bimbofication, cum addiction and race change (caucasian to asian). Some minor themes are maids, fucking your boss, lactation, tight/shiny clothes, submission, for example. Different play styles may cause you to miss certain transformations. If you do miss something you absolutely wanted to hit, don't worry. Just post in the thread asking for help. I have a tendency to respond to everybody, and even if I don't, there are plenty of friendly people around to help you out.

There is now a Google Forms survey that I plan to keep running for a long time, probably. If you don't like dealing with Google, I understand, but if you feel like voicing your opinion on my stories hosted on TFGS or elsewhere, I'd appreciate hearing it. Simply click on this link and fill out the questions, only if you're interested and have the time: https://docs.google.com/forms/d/1NcluzvD4bXF5yzc9CAK3RwW1Q-DPNZg0tmEYo_HuQ2A/viewform Please be honest and only take the survey once!

Somebody seemed confused so I'm putting some info about it here: I have also written multiple linear, traditional short stories. You can find links to them in this pastebin: https://pastebin.com/7fvprTTr

• The story now runs until Week 4, Day 4. Sorry about the small update, I don't know when the next one will be.

• Sloppy Slut modified to be a Cumslut tattoo
• Tight Clothes fetish on Week 4, Day 3, with a penis modified. You can now choose to be humiliated by the experience instead of feeling like a goddess. If you have the Superhero Clothing fetish, your outfit will just get very tight and cause your boyclit to peek out of your panties for a similar effect. Text will say you feel like a constantly available slut. All of the text is flavour, and has no real gameplay difference, you just get the Tight Clothes fetish.
