All of her recent content is strictly exclusive and as far as I can tell there are virtually no freebie galleries.
As for the boob job, etc. I'm cool with it. It's not a horrible boob job in my opinion (Jenny Pousin's are bad, Lindsay Marie's with one up and one down, etc. there is a thread on Peachy on this very topic). I do like the workout teases. Susanna has always been in phenominal shape. Now with her lean physique, her tits-a-poppin' look and unique photography, I think she's doing great and hope she keeps it up for some time to come.
