"How stupid! We are stepsisters." "Only according to the law." When my stupid father remarried, I had 2 beautiful half-Japanese sisters. The older one, Rika, was my classmate, while the younger one, Karen, was a year younger than us. Living with girls in a multicultural household for many years, somehow it became common for us to be naked in the same motel room. When my cock was stimulated, my stepsisters were extremely curious. As a teenager, I couldn't control my sexual desire for more than 3 days at a time. After finding the joy of sex, we continued to have sex at school and at home.
