Behind Closed Doors
Behind Closed Doors is an incredibly fun sandbox life sim you can play instantly in your browser on mobile or PC. The game kicks off with a brilliant feature, letting you completely customize your exact relationship to the household you live with. Whether you want to be a simple tenant renting a room, a step-family member, or something completely custom where you pick their names and genders, the choice is entirely yours!
The plot hits you fast when you suddenly develop a rare, life-threatening hormonal imbalance where unchecked arousal brings intense pain. The paramedics drop the ultimate bombshell: the only medical treatment is immediate, frequent release. Now you get to live your daily life in the house, navigating this awkward reality while your roommates develop new, very hot feelings for you.
Will you resist the temptation and keep everything wholesome? Pftt, let's not kid ourselves, eh? You get to slowly influence their choices, carefully corrupting the household until they become absolutely addicted to your cock. Just make sure you manage your stats so you don't overdo it and literally die from being too horny. It's a wonderfully naughty premise that delivers excellent replay value.
