Succubus Nightmare

Succubus Nightmare is a 3D erotic puzzle game in which you play as Charlotte, the older of two stepsisters, navigating a sprawling manor controlled by a succubus. Alongside your sister, you must find a way to escape while uncovering the truth behind the mystery—and discovering whether someone else is orchestrating events from the shadows. The game features exploration and puzzle-solving across two main environments: the Manor and the Church. You'll interact with the environment, solve puzzles to progress, and encounter brainwashed servants whose advances you must evade. The gameplay emphasizes both escape and seduction mechanics, with failure resulting in erotic punishment scenes. The game includes 25 unlockable sex scenes, each with free camera control.
