Please keep in mind that you are not obligated to introduce new characters over and over as you go to keep crowds interest. To me, you have right mix of characters to develop story for a while exercising individual relations and kinks, nothing wrong to have multiple sex scenes featuring same sex kink if it wrapped in passionate flow with each per story, people like to replay those that feature their favorites and prefer more passionate scenes with their favs that grow with their sex appeal/interest. So even with preset number of characters if it is implemented nicely, this works better than keep throwing in more new look alike characters to exercise same sex iterations as each new character has to run trough bj/lick/vag/anal cycle, as this complicates story as you have to pack new charisma for each that should be very diverse to not look bland or too bogus. Also, please no extreme size orgies like NLT does recently, where all story characters squeezed in, permutated and timed by penetrations in single scene, those are just vibe killers imoYeah, for sure, but later.
No, I have no plans for that, but a new character will be revealed in Chapter 4. She's not a trap, but...
Good luck and thank you!
