Succubus Simulation: The Night a Lazy Little Devil Slept in My Bed

A simulation-style adult game set on a summer night. The protagonist returns home exhausted from work to find a beautiful succubus named Lilia asleep in their bed. She has come from the demon world and must engage in intimate activity before dawn or she will perish. Drawn in by her supernatural allure, the protagonist begins a one-night romantic encounter. Gameplay involves interactive touch-based simulation sequences to progress intimate scenes with the heroine, leading to six different endings (one true ending, three happy endings, two bad endings). The game includes substantial adult content even in the trial version, which covers approximately 70% of the main story.
