There's another amateur model called 50K Wife or something like that who takes pictures like that, without showing her face, that I ran into on one of those compilation blogs...give me a minute and I'll try and dig it up.
Edited to add: I was right --
she's on HugeHeavyBreasts!And as the author of the blog says, "A big thanks to
50K Cups and Charlie for sharing these pics."
Pal says: Kudos on the ID Zook! 
You got it,
Pal!
