Honestly, BF games are actually a genre that's an unpolished gem, majority of said games are lacking, and then you have stuff like Karryn's Prison (The current best BattleFuck game, and will be for a long time), Monster Girl Dreams, Saria Reclaimed (what it could've been), or if you swing towards futas and traps, Tales of Androgyny (the main downside is that 90% of the content is with MC as a sub)...
In text based games, you have Fenoxo titles, such as Trials in Tainted Space aka TiTS, or Corruption of Champions 2 aka CoC 2. One that's also slowly building a name for itself is Lilith's Throne...
