I doubt it would be possible since it is branching off from the normal NTR ending and probably won't have too many differences (or else it would wind up just becoming a full fourth ending)
I mean...i thought that it was supposed to be a fourth ending to begin with, not just some "what if" scenario of the basic NTR ending, and that it shares the name "NTR ending" with the normal NTR ending simply because...well, Leto gets NTR'd, just by different people, or i guess i kinda figured that both NTR endings would be somewhat similar when it comes to the ACTUAL last quest of the route, but i also thought that the conclusion itself and the execution of it would be drastically different as well.
Up until now i was sure as shit that most of what happened in Update14, where the girls are pretending to be prostitutes, was so that the slut NTR ending is not so out of the blue and that the characters introduced here can be eased into that Ending that much...smoother, i guess.
I though, and i still think to be honest, that this guy's gonna replace Ulrod in the slut ending and train Cyanna to be an actual prostitute, or something along the lines of that, i mean why else would he not only be introduced as who he is, but tease the audience by saying how he would love to train Cyanna multiple times during his brief screentime, or say how she was made to be a prostitue with a body like that, and not only that but when Ulrod finds out about this scene above, he demands to know who this person was, and Cyanna just casually lies about his appearance and says that the guy was a white haired or blonde (i don't rember which) elf, a polar opposite of this bearded brunette human.
I also believe that the old(er) prostitute who was introduced in this same Update as well is gonna play a big part in Rose's slut NTR ending, either directly or indirectly, and that it's gonna have something to do with how she was feeling while she was blowing those two pirates, how she was saying that she's happy that she can like satisfy her subjects or whatever and that she feels so much more free here in this moment than she ever felt at the Duke's estate. Don't qoute me on this cause it's been a while since i played that quest so my memories are kinda foggy, but i think this is what happened.
This is not relevant to what i was saying but it's kidna funny, when i first played the Update and saw Cyanna lie about this guy's appearance, i though that Ulrod would become a racist against Elves, and that he would start messing with that white haired elf city guard cause whenever he would see him, it would remind him of this misterious guy who basically "touched his property". I'm talking toilet duty 5 times a week, missing gear, holes in the tent that he's sleeping in whenever they're on a mission, shit like that, or just straight up get him fired, that would be hilarious lmao.
