I don't like this type of plot, it has too much of "normal couple" feel, nothing taboo, too much romantic bullshit and stuff. Incest plot , whether we talk about comics or videos or text stories absolutely needs to have "prohibited" and taboo feel in it. Clearly, when story is dragging for too long, inevitably sex scenes don't have that overall taboo feel, and that's why i always said that it would be much better and wiser to close any incest fantasy story after let's say 4 or 5 chapters. As soon as relationship between two main characters becomes "regular" , artist need to simply end that story.
