Behind Closed Doors
Behind Closed Doors gives you total freedom to design the exact living situation of your dreams. You start by setting up your household, dialing in everything from names and genders to whether these characters are just landlords, step-relatives, or completely original creations. It is insanely satisfying to build your own custom cast before jumping right into the main storyline.
Things take a dramatic and hilarious turn when your character is diagnosed with a bizarre condition. Every time you get an erection, you suffer from overwhelming heat and pain, and the doctor's only prescription is constant, hands-on treatment. It forces your newly created household into some incredibly compromising situations as they step up to save your life.
The gameplay loop revolves around guiding their behavior, slowly shifting their boundaries until they are obsessed with your cock. You really feel the progression as you systematically seduce each member, turning a standard living arrangement into a truly lustful harem. You just have to balance your stats carefully, as pushing yourself too far will literally kill you!
