Succubus Prison

You've been dragged into robbing a house by a couple of thugs, but what you discover there is beyond anything you could have imagined.

You stand outside a house on the edge of town, dragged there by a couple of guys you can't say no to without getting your kneecaps busted, and told that you were helping them to rob it. It's only three sisters who live there, they said. It's an easy score, they said. You sneak inside and start searching the rooms, as instructed. It's dark, and even though you don't see anything worth taking, things are going smoothly so far. Then the screaming starts.
