First of all, excuse my very limited english. In the scene you are refering to there's a brief attempt of vaginal fisting, and it ends with Veronica taking some piss in her face. But I'm afraid that these two moments only appear in the european version.
As far as I know, Miss Stone has not do anal yet, besides some anal fingering for the amkingdom website. And I agree with you: when she decides to do anal, she will become, without any doubt, one of the hottest girls of the moment.
