Asian BBWs (well, really, all BBWs of all races, nationalities, ethnicities, etc. to be fair, but the Asians have that special quality I can't get enough of). My own wife is Korean, and Chinese, Thai, Vietnamese, Filipina, etc., girls all get plenty of attention from me. The reason we focus on the Japanese girls so much, of course, is just that the Japanese erotic entertainment industry is so Goddamned good.

interview at plusforum.com gives us some information on the lovely Sylvia. She was 25 at the time of the interview in April 2011, making her birth year 1986 or thereabouts. She was born in Torrance, California and raised in a primarily Asian environment. Her larger than average size made her self-conscious, but she decided to try modeling after noticing more plus-size ladies entering the industry. After serving in the army, she started modeling in 2007.
Model Mayhem site says she is 5'10", with measurements of (US) 42(D)-34-42", dress size 14. She grew a bit by the time her statistics were given in her profile at heffermanagement, where she is described as dress size 14/16, 44(D)-36-44", (112-91-112cm).
