My girlfriend's mom Sophie

Sophie is the mother of my girlfriend Margaux. We are still students and I am going more and more often to my girlfriend’s house. Sophie is quite cold and distant with me, she works in a big company at a high position, so she is quite strict and severe. Margaux’s father left when she was little, so Sophie is a single mother. I want to try to get closer to Sophie because it will make Margaux happy, moreover it is a Catholic believing family so Margaux would like me to have her mother’s approval for our couple, moreover there is no sex before the wedding. She has 40 years old, caucasian, dominant slut face, she has long brown hair, slim shape, wide hips, slim waist, she often dressed with office suits , she wears small gold catholic cross necklace.
