The Sissy Girlfriend Experiment is a wonderful adult sissy game in which you will play as a young man who has to move in with his sister. He is kind of shy and not the most dominant male in the room.

It’s a game of sissification, gender fluidity, naughty gay, shemale, and straight sex, plus many other kinks and fetishes. You can enjoy the game from our site for free. It has original artwork, lots of characters, and a well-written twine plot line taking you to all kinds of endings.
