An EroGe (Erotic/Choose-Your-Own-Adventure PC game) from Japan.
Your childhood friend and now girlfriend suddenly becomes president of the United States.
Considering the genre, you apparently will have sex with her.
The trailer is hilarious, though, and thus this is probably the only EroGe that I am actually interested in playing. Will be hunting for torrents, as there's no way I'm importing for $105.00.
