Describing sex acts between a 12 year old and a 10 year old is probably in violation of "kiddie porn laws" in the U.S. even if it is fiction. I don't know what the laws are in Canada.
The situation you object to does happen many times in close knit families. Please note that this situation is strictly between the participants, no adult condones their actions and no adult benefits from their actions. I would ask you to reserve judgement until you see how the situation is resolved.
