DISCLAIMER: This is Rowling's playground. I just mess about in the sandbox.
AN: Do NOT read if you do not like: INTERGENERATIONAL 'SHIPS or MENTIONS OF INCEST (though nothing happens on or even off screen). THIS IS SUPPOSED TO BE SHORT.
Sometimes Narcissa wonders if it wouldn't be better - ideologically - if her illicit affair was with Draco. It would still be a betrayal of her husband and in violation of the sanctity of marriage, and it would still be a relationship with a man far too young for her. However, in times of war... there are some who might argue that incest is less taboo than sleeping with the enemy, especially with one as close to the Boy Who Lived as Ronald Weasley is.
At least Draco is on the right side.
