Welcome to the dungeon....

When a mysterious customer offers cute, little waitress Grace an invitation to his house for dinner, she is too curious to turn him down. An evening that starts perfectly normally ends in a way Grace would have never predicted when he invites her down to his "workshop" to take a look at the machines he's spent a lifetime creating.

There, she understands exactly what makes him different, and discovers something new about herself in the process. When he invites her to play, Grace begins to realize that she can't get enough.
