you can't start with anal. you're a porn director, not consumer. your goal is to make money, not porn. no one's in porn for porn's sake.
you've got to build a fan base first and then introduce the types of scenes that virginal porn consumers wait for -- anal, gangbang, interracial, etc.
so for her first scene it'd have to be standard, probably casting couch kind of thing. then do the standard gonzo bullshit. eventually, lesbian scene with an established pornstar. THEN you do the anal scene, once everyone's primed and ready to spend actual money on it.
