Basically Noblewomen (or their Maids) who are bio-sex females but also have a dick. These stories will obviously be pornographic in nature since, as far as I'm aware, you can't have a major trait of your FL be that she has a dick and then not utilize it...
Criteria to meet the list:
The biologically female protagonist has a dick.
Can have a modern setting but the futa must exhibit Villainess, Heroine, or Maid-like traits.
