Water Closet: The Forbidden Chamber is an erotic visual novel in the retro style of 90s anime. It depicts both traditional heterosexual relationships and intimacy between two girls. How the story will develop depends only on the user’s choices, which he will make during the course of the plot and improve the relationships between the characters.

The action takes place in a typical hospital inpatient ward. Patients come here for treatment for various non-communicable diseases and most often they have absolutely no way to brighten up their leisure time. But everything changes in the department when the strange doctor Nikolos takes over their treatment. At first, all his dirty jokes and conversations seem to be nothing more than an attempt to relieve stress from his patients. But over time it turns out that he is not at all opposed to bringing them to life. In addition, next to him is an equally lustful nurse, who at least hides her desires and preferences, although sometimes she locks herself in a cramped toilet stall with her boss.

Water Closet: The Forbidden Chamber tells the story of 5 girls who arrive at the clinic for various reasons. But each of them ultimately becomes participants in real sexual games between medical staff and the people for whom they are responsible. Sometimes such intensive therapy allows girls to discover true pleasure.
