The MC is actually developing and the manga has a neat lil gentle femdom thing going on. If there isn't any NTR /NTRbait I'll have no other option but to rate this highly.
@Lolipop_Candy true but the protagonists could always do screenings during preganancy and utilize abortions to prevent a prevalence of affected children. :/

IIRC incest is fine for one generation but shit realllly gets wack after that. It really depends of the family's genetic history (example, recessive Hemophilia).
