Edit: On the whole Cait anal/NTRish thing, I'd argue it's not that its NTR - Cait is clearly a huge slut and isn't being stolen away from you because she's never Your Waifu to begin with. It's that it's kind of a pseudocuckoldry thing when Cait specifically says she will not let you do anal with her, and teases/hints that this could change in the future - this is clearly bait/hinting that this will be a Special Thing she shares with you. But then, in various loss scenes, she proceeds to have anal done to her and goes on to clearly and in detail enjoy this state of affairs. and then after she has her anal virginity taken by force, she still won't let you do anal with her. Then, to add a bit of extra spice, it's been mentioned by the writers that there IS planned to be special dialogue/changes in the scene where Cait eventually lets you do anal based on if its her first or not. Basically, "there is sex Cait will have that Only Other People get to do with her, never you" and that can remind people of NTRish vibes.
