Hoping to find a ts provider next weekend in LV for a massage and frot session.  Anyone have any recommendations?  

I'd think that nearly any of the ladies providing full service would be happy to massage and frot for the right price; I'd guess relatively few would offer discount for the limit in service, but IDK, maybe I'm wrong on that.   If you are looking for such a discount, I'd think things get more complicated.

After that, it's just a matter of what you want - busty, more flat, short, tall, skinny, ethnicity, athletic,  top, bottom, verse, gets hard or don't care, etc., etc.  I'd start with a search of the reviews here, and/or just going to the usual websites: tsescorts, ts4rent, eros, etc.
