Nickname for the San Fernando Valley in California, known for having a lot of porn studios.
I moved to the Silicone Valley with my rubber tits to pursue a career as a porn star. After starring in over 200 creampie gangbangs, I upgraded my tits and ass from rubber to Silicone. I get even more, and higher quality, dicks in my pussy.
