I would suggest doing a search for reviews featuring Ariana in them. I've reviewed quite a lot of her scenes but don't recall many of her just taking on one guy, she just needs more than one man,hehe. Good luck!
Any porn film that has anal and Ariana Jollee equals her squirting 95% of the time. From my recollection of all the films I seen with her only a few disappointed me (when she did not squirt, but her performance is always great), but if I had to pick some great films with her Riot Sluts, Booty Duty 11, and Double Parked 8 come to my mind. Like Bono-ONE said check the reviews to see if it sounds like something you will like. Other good movies with Ariana are Ass Cleavage 3, Assploitations, Big Black Beast, Juicy G-spots 1, One In The Pink And One In The Stink, Strip Tease Then Fuck 3, and Truly Nice Ass 4 also come to mind. I hope this is a good starting point for your search.
Everyone's tastes vary, of course. That said, I would particularly encourage you to view the two films from Zero Tolerance that squirtfan1 mentioned: "Ass Cleavage #3" and "Strip, Tease then Fuck #3"
I was absolutely blown-away by both these films (which I watched this past week)! Zero Tolerance's Mike Quasar and Wendi Knight are seriously good adult film makers. Quality absolutely just oozes in both these productions. Chances are that this will expose you to a new studio's products too :)
Bottom line: Ariana's scenes in both these films are awesome! In "Ass Cleavage #3" Ariana has a particularly excellent missionary fuck segment where she obviously gets off
In "Strip, Tease then Fuck #3" Shy Love and Alexis Malone are also great. In "Ass Cleavage #3" Jane Darling and Dark Angel are also great. Every scene in both films is good to spectacular. Personally, the Alexis Malone scene was off the charts!
If you like POV then I recommend "Multiple POV 1". Her tease at the beginning to the camera is just so sexy and the whole scene builds to a pretty outrageous conclusion. Plenty of ATM, anal and squirting onto the camera which she then licks off!
She's incredible; it will be cool when her website is up and running.
