A bi-crossdresser, hungry for humiliation, presents their sissy self to the Femdom mistress. She teases them, making them caress their body, now unfamiliar yet tantalizing in a corset and stockings. She orders them to sit on a dildo, grinding and moaning as they take it in. The sissy slut, high on feminization and shame, begs for more. The mistress grants their wish, binding them in a harness and filling their tight ass with a thick, realistic dick, fucking them mercilessly until they're left panting and spent, a true sissy anal slut.
