In my first run I am trying to see as many scenes as possible but my goal is that MC end up with Sis in the best possible way, she is simply the female character that I liked the most of the three novels, the most beautiful and genuine. It would be nice if she could have fun too, for example, get a good massage from Jazmin, or share a scene with the music producer (Hank) or something, of course, if the users choose to play that. If there is enough trust between the main couple, love does not have to be affected, and it would be a way to offer more variants to users without affecting the complicity between the main characters. Nothing of this have to be under the NTR tag.
