This is kind of games which I am looking dor and sadly there is a very little amount of them. Darktoz's Asylum have something about it, but it's more about being a forced patient. The perfect example of this genre are CoC prisoner mod (implented in revamp mod as jail) and Surrendr game, but both are unfinished and long time abandoned. Concubine game wanted to be about it, but, imo, is too mild/unstrict and gives player too much freedom. If you can enjoy sandbox without a story and Bugs from time to time you can try amazing Sanguine Debauchery mod for Skyrim. I wouldn't call it a game, it's more like a framework that needs to have stories implemented, but still very interesting to try. There are also Isle of Femme game in development which shpuld be about it and I am waiting playable build in anticipation and old game Whorelock's Revenge (same author currently working on No Haven) after finishing transfer of this old game from Rags to Twine is going to finally start adding content and he was a fan of CoC prisoner mod, so he wanted to implement the same thing in this game but rags engine is just bad. If anyone knows more games about it - please share.
