Has anyone else played absolute obedience?

Because I'm absolutely in love with it. It's a PC game set in post-war Nazi Germany. It has absolutely no historical accuracy but lots of hot guys. It's about a gay couple, Louise and Kai, who have a sort of detective agency. They take on cases where people who have a problem with someone else and they go have sex with them. Not exactly prostitution, tho. It's hard to explain. I'm super addicted to it right now. Anybody else played? Or know any games like this?
