A formal mistress
I am an accomplished professional. I can support myself quite well. However I'm a woman, and being a woman I am under the power of a man. I don[t pay rent, or have a car payment. I have an allowance for daily expenses, currently five thousand a week. I can't spend it. 100% of my salary goes into savings, he invests for me and I have over 500 thousand in my portfolio.
I entertain in my home, or rather in the apartment he keeps me in. I use to think mistresses were whores. I'm not a w****, I'm a mistress. A mistress is like a junior wife. His formal wife is number one, the mistress is number two. I'm number two. I have duties, it's not without duties. I relieve his wife, she will tell you that s** at her age can and is a burden. As the mistress that's one of my duties. S**.
As a matter of fact, when I was seeing him on the side his wife insisted he either formalize me as his mistress or let me go. If he let me go he was stupid. That's when the agreement was drawn up, for my protection. It's like a prenup, with guarantees of support. She hired the lawyer and she made him sign it. Or he had to let me go.
As the junior wife I pay attention to my duties and stay in the background. However his wife took me to a theatre show and introduced me to her friend as his 'young wife'. My look brought this comment 'you are and don't think otherwise'. That was five years ago when she had him sign my support agreement.
