About this game

The developer's description, from the game's Steam store page.

Succubus Nightmare is a 3D erotic puzzle game. Play as Charlotte, the older of two stepsisters, as she leads her sister out of a sprawling manor controlled by a succubus. As the story unfolds, the truth behind the mystery slowly unravels—but is someone else really the mastermind behind all this?!
