The best brothel game I know is
Pale Carnations, albeit it's not typical brothel game.
We're basically fresh employees in a secret brothel for elites where there are "ladies for pleasure", i.e. high-class whores who aren't your average harlots, rather high class courtesans who can fulfil every desire. What's special about it is that every year there is a competition for the best whore where 3 candidates compete in some very perverted games to achieve money or some other profits thanks to patron's influence. Hence we have here businesswomen, academic teachers or housewives whose situation has been exploited by patrons or other people involved with the club and are manipulated/coerced to take part in these debauched activities.
They aren't slaves and they can resign at any moment but the potential prize is too good for them to reject and since the existence of the club is secret they don't have to worry about their activities becoming known to others. IMO that makes this game that much more appealing, knowing that we don't have lowest women who knew nothing else other than fucking but normal women (sometimes very intelligent and at times even wealthy but just bored with their lives) who slowly get depraved.
