How can I be a mistress of a rich person and earn money that way?
First, it's a myth. It is extremely difficult to be someone's mistress, especially wealthy people. And the mistress they find are not escorts. Their mistresses are people they have a personal connection with. Usually a secretary or someone they worked with, and they get to know them and like them.
But there are also many escorts who have wealthy repeat clients who visit them every week and buy nice gifts. To find those wealthy clients, you just have to be lucky, and know how to build a relationship with the clients you like. And you know men – if they like you, they will do anything and buy anything for you.
