Back in the day Alina Li and Evelyn Lin worked with the Asian guy from Amateur Creampies. In her OF Evelyn filmed with an Asian guy as well.
Back then Keni Styles worked a bunch. There's literally only a handful in America who consistently work for other productions like Leo Vice, James Bang and David Lee. There's Banana Fever too. Most are indie doing their own thing like JeshByJesh and Kenny Kong.
