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
v0.14.8
- In this version, you will be able to enable a new rival called The Blackmail. (Wait a moment, Jammye! I thought this update was going to be Rival: Sissy Stalker? It is. I started working on the Sissy Stalker character, but I couldn't come up with a good idea for the main character to hang out with the stalker. But... What if they were going through something similar? I thought the Rival: Blackmailer and Rival: Sissy Stalker would work better together. As one Rival with two characters). Depending on your settings, you will find more cuckold content in the early game, while making your sissification faster. If things get too rough, you will always have the option to drop out. You will also meet the sister/stepsister previous roommate (from the Roommate comic), who will be in the same trouble as your character. Together, you will figure out a way out of this mess. The game will tell you when to stop and save, so you won't miss anything on the next update.
v0.14.7
- Hello everyone! A new version of the game is now available! The Unorthodox Clinic now offers new services. The previous update added books, which allow you to decrease your stats (body/flexibility/mind). Doctor Paige now offers the possibility of forgetting some of the main sex. skills in exchange for experience. You can now talk to the Doctor, share your experiences, and ask for a physical exam. Another change: Sperm donation and volunteer services are now available, and you can choose whichever one suits you best. What else? Grazie's story goes on after she is no longer a virgin; she got a job at the clinic. Also, meet two new characters. You might know this one from the comic 'The Bride'. Yes, the husband (Gary) is now at the support group, looking for help. There's another one, Brandi, or is it Brenda? I keep getting it confused.
- Now, before I talk about the new comic, let's talk about the next update: Rival system, sissy stalker. You've chosen this one, and it will be available next month. I recommend reading the new comic, The Roommate, to learn a bit about this character. You will realize that some material from this version is getting ready for this new troublemaker.
