Basically, the title. A girl named Sporke gets dead drunk, wanders in a forest in which it rains alot. She encounters something which has the potential to endow many cavities.

No, even though the title sounds perverted, this is only about the first time you ever play the game. And get excited. And run around, filled with andrenaline, chopping up any- and everything that hops in front of you. And now I've given away the plot.
