There might be some with your description of 30+ so maybe my advice isn't the best.  Phx Cityvibe doesn't seem to have anything that fits your description.  La girls are more 20+ and are typically enhanced boobs.  You take your chances with an unreviewed girl. Might be LE or a scam. I'd recommend one of the well reviewed Thai girls. You'll have to get verified that your a good Guy, see them at their place first, then ask about your special fantasy after they get to know you real well.
