About The Sissy Girlfriend Experiment

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.​
