Femdom's mother-in-law

This is a story about me and my mother-in-law. My name is Lucien and I am 30 years old, my wife's name is Janet and she is 29 years old. My mother-in-law Margaret lives with us. She is a tall woman of 65 years old but looks younger than her age. I know that she loves to dominate men and intends to dominate me, the question is how is she going to dominate me?
