The Sissy Girlfriend Experiment is an erotic game with erotic text and images. It also contains the following themes: Forced transformation, M2F, Femdom, Cuckold, Cumplay (optional), BSDM (optional), Sissy, Anal sex, Group sex and oral sex. If this kind of content isn’t allowed in your country or you find it offensive, please, stop right here.

You will start with a male character living with his sister, during a special night you met an older woman which becomes your girlfriend. You also have a friend (which you can choose the gender) who is the only person that you really trust. As the story goes on, each of those characters will play a part in your transformation.

This is the first version, which works as demo of what I’m creating. The game will stop when you reach the doctor part (which will be a new character that will also have a part in your transformation).

- Keep in mind that this is an early version and it will improve in the next versions.

- There’s no side quests available in the free version, but there’s two (teacher and gym bully) available for patrons users.

- The game will always be for free but side quests will only be available for patrons since it’s the way I’ve found to thank my supporters.
