"Help! My Girlfriend has an Alien in her Ass" is a smutty, silly little story with a little bit of interactivity (your choices will affect events, characters, and relationships, sometimes quite dramatically, but won't change the main thrust of the story that much, even in future versions).
With this game I tried a narrative frame that I haven't seen other games using, of a character telling the reader his story directly, with your choices being the things that you say to him. I hope you like it!
