I'll read tomorrow, have a stomach ache today. But with the incest harem I think both ways can works just fine. Really just depends on the writings and the characters. Although I do agree no matter how wholesome there has to be some kind of edge to it. Some kind of acknowledgement how fucked up and taboo the whole thing is or it ruins the taboo nature of it.
Anybody in pursuit of a Harem is a kind of power hungry tyrant
