But once it happens she takes one look at you and laughs, oh no, YOU can’t be a husband, you’re too small and submissive, you must be her sissy stepdaughter instead! Oh no! you weren’t manly enough for your perfect woman, so she is going to find a real husband and train you to be a perfect sissy stepdaughter and take that new husband’s cock, this couldn’t have gone worse!
