I think she is great and moving to professional production houses was a good step. Also like, that unlike most other Asians, she is not afraid of going down and give a rim job. The scene with Hollywood Cash and Jason Luv looked like spontaneous and not planned.
As far as why she keeps fucking the same "ngga", I think they both signed a multi-scene deal with Jules Jordan. Jules and Evil Angel seems to do that more often than other production houses. Also, it could be that they go along well and she probably finds him clean without BO. Most porn stars don't do another scene with someone who has poor hygiene or pushy. One reason why so many porn stars repeat their work with Isiah Maxwell.
I have heard Dredd is also good in terms of hygiene and behavior, but that dude just sucks when in comes to performance and is the very definition of boring. Throw in a surgically modified thing called dick and 0 drop of cum to make it completed package of waste.
