Looking for incest stories where it takes a long build up, there is reluctance, and the participants don't instantly hop into bed.
I want a story with only one relationship, no harems, no multi, just a mother/son, brother/sister, father/daughter, grandmother/grandson... No cheating so the parents would have to be divorced or widowed. Children need to be unattached or also divorced/widowed.
I know I am asking a lot here so if no one has any ideas I will take anything close.
Thank you in advance.
