I've got a few busty blondes for you to contact, CindySpice, Jackie Jewel and Roxy.   All are very good at what they do. They are real nice and lots of fun to be with.  There are of course other choices as  well.  LJ come to mind, other then that do some homework and see who else is out there.  Contact them and go with the lady you like the best.

Any additional details your willing to provide is helpful.  For example, "busty" is a general term.  If you prefer above or below a certain bust size, cup size, natural or "enhanced", this would help.  You also might consider dropping $20 on a membership. This give you access to the full database, where you can specify your search.  You can also see the full reviews.

One more thing - if blondes are not an absolute requirement, check out Brie Michaels.
