Overview
The Sissy Girlfriend Experiment is a 2D visual novel for players who want a slow, character-driven corruption story with a lighter, playful tone.
Story
A young man living with his sister meets an older woman one night who becomes his girlfriend, while a close friend remains the one person he truly trusts. As their lives intertwine, each of these characters pulls him further into a transformation he did not expect and cannot fully control.
Gameplay
Play unfolds through dialogue-heavy scenes and choices that shape how the protagonist changes over time, with new locations and side characters opening up as the story moves forward. Stats tied to body, mind, and outward presentation shift based on decisions and events, nudging the character further along his transformation, and side activities like reading found books or gambling offer extra ways to influence those stats.
Features
- Hand-drawn 2D art with animated scenes
- A gender-bender corruption arc built around three key relationships
- Optional side systems, including a bookstore and a casino, tied into stat-based character growth
- Group and same-sex content woven into the main storyline
Installation
1- Extract to desired location. 2- Click on "executable_name.exe" to start playing.
Changelog
v0.14.6
- Hello everyone, the new version is now available with a new place to explore: The Docks. Meet Abigail at an old bookstore and find her missing books. Of course, reading them will cost you something. Erotic books are part of a new system to help you lower stats (body, mind, flex) faster. Feeling lucky? Go to the casino and try your luck! You can only lose money and your dignity. (: Most of the games are rigged) There's also a ship with a strange crew with an unknown cargo, but you will have to pass by the crew to access it.
- This update: Just like happened to Downtown, the Docks will slowly grow, adding more fun and variety to the game. I have some more ideas for this part of town, and you can expect to see them in a new poll soon. I like to think that 'The Park' is the rich part of town, 'Downtown' is where the business happens, and 'The Docks' is the dangerous and shady part of the town.
- About the comic: I'm still working on it. The good news: All images and dialogue are done. Still, there's more work to do, and I believe it will be available in July.
- Next month: We're going back to the unorthodox clinic to improve some of the old features there and add more side stories to be explored.
