Now my sister who became a neat and clean married woman. She had the physical characteristic of having an unusually long tongue. When my younger brother was a student, my older sister worked as a pinsaro lady under the influence of her divorced parents and made a living. I didn't know that, and accepted my sister's fellatio practice. Gradually, I got to know how comfortable it was, and it became a relationship where I did not only fellatio but also SEX.
