@redlion75 maybe stop reading if it isn't for you? It's fiction and not everything is going to be perfect all the way through a story :)
Seems more like mislabelled BDSM where the actors call one another siblings as an extra kink. This crap never makes sense to me when an incestuous love does this 180 turn into humiliation and dominance during the sex act.
