My two major kinks are domestic discipline and pregnancy. I'm a huge fan of traditional marriage, but not only that, also incest. Domestic discipline doesn't mean that your character doesn't love mine- that's why they discipline them.
Essentially, it's a couple- married or not- who winds up in a relationship with the male head of household taking control of his woman. He controls what she wears, how many kids they have, the money... basically every major aspect. Think 1950's relationship. When she disobeys, she gets spanked or beaten- it's punishment, and only fair.
Pairings I like:
Husband x Wife
Father x Daughter
Forced marriage/mother hood
Creating the perfect wife
Young marriage- like her only being in her teens. Late teens, of course. :) I'm open to any!
