続悪徳医　女医篇

Also known as Zoku akutokui: Joi-hen, 続 悪徳医[女医篇]

After being brutally gang-raped, a young girl grows into a woman with a double life: She's a well-to-do doctor by day and, by night, a revenge-driven streetwalker who uses sex as a weapon. That all changes when she finally falls in love and begins a new life with her husband -- only to discover that he has a troubling secret of his own.
