Karina, 30, is a half-married woman with an American father and a Japanese mother. Currently I am an English teacher. My husband takes good care of himself, but sex is normal. I have never confided to anyone the desires that I have stored in my heart. I'm masturbating by imagining myself being humiliated by an unknown man. I want someone to see me ashamed. I want to expose my indecent self and go crazy.
