While on the dom/stag route I did not get what you had in ch.18, In my playthrough Laura called to tell me about her going to Nathan beforehand, I have to agree that even on the Stag route there is dialog which has nothing(!) to search in a stag path!I don't know if it's a bug or if it's some kind of misinterpretation from my end, but in the dom route has some humiliation dialogue about dick size, example, the girlfriend says nathan can reach deeper place that the MC can never reach. Should this kind of dialogue to be in the dom route?
In the end of the chapter 18, the MC receives a message from Nathan saying the girlfriend went to his loft for a quickie and the chapter ends. Did the girlfriend had sex whithout communicate the protagonist (cheating)?
This two situations look like the narrative is going to the Netorare side and not Netorase like the premise said to.
It is one thing if Laura tells you about how much fun she has, that Nathan is good in bed and it is great you are supporting her "slutting around", BUT it is another to see text like paraphrased "he´s better than you´ll ever be" or "don´t masturbate until I am home, cucky"! WTF? This is NTR diatribe and should be firing in the cuck/NTR paths, but never in a stag NTS path!
