As a salesman of a construction company that doesn't get upset, I have a mistress relationship with a married woman, Yumi, who I met on SNS. I regarded her as her "convenient mistress" who accepted all the things I wanted, and when her stress accumulated, I called Yumi and was absorbed in her nasty acts. She accepted everything I wanted because she could afford it as an adult woman, and I was a devilish beauty who drowned both physically and mentally because of her attractiveness as an adult who showed that margin.
