Only two girls I can think of is Boa (only half Viet though) from La Visage in San Jose though. The other is Tami at Gold Coast in Vallejo. Tami is about 5', has an amazing body, and she's really tight. I think she does kegels daily. And she had an ass good enough to rim, and I did. Boa only works Monday's and Thursday. And Tami only does Thursday to Sunday.
Locally to Sac, I haven't come across any.
