There is a TLDR at towards the bottom...
...
TLDR: 1. If there is no MC incest planned that should be added under the genre spoiler tab as, perhaps, Incest (Non-MC) or Incest (NPCs Only). 2. Honestly, I just don't get the reason for not making voyeurism/sharing/swinging fully avoidable instead of skippable. The closest thing to an argument has been "realism," but you are applying unrealistic porn-logic elsewhere to things that are less controversial. The fact that you have incest planned at all stretches credulity to many, as just one such example. Hence why you added the option in the start to turn it off for two couples I imagine. If you see the logic and good sense to have incest be *fully* optional (a fetish that is far less polarizing, especially in small doses) then why wasn't the same done for the voyeurism/sharing/swinging? It seems odd to treat the one as avoidable and the other as skippable. And if the people who are used in the possible incest scenes talk about struggling with the taboo of their relationship since they were "childhood friends" or something then you have truly cast the die that realism means nothing. And if they don't talk about the taboo when it is turned off, then again, you showed a willingness to write and render two different scenes in both form and function for one fetish but then didn't for another far more polarizing one... which leads to the question of why?
I've rambled again, but that's all of have for today. Have a nice evening everyone... or morning, or whatever, time zone dependent, I guess.
Edit: Seeing more specifics about the Cat scene that were given below that tried to say that it was “wholesome” and “almost sweet” just adds to my sense that it is largely there using porn-logic and not realistic in any way. But it is what it is I guess.
