There seems to always be 1 or 2 porn babes touring DC at any given time. So you might just want to check the message boards for ads , as well as EROS. Be prepared though, if they are traveling for an agency you will face pretty stiff [ I said "stiff" LOL ] fees.  A couple local agencies will occasionally have a "B" list porn babe available , again , check the DC board.  Claire La Femme has had DC as kind of a base for a number of years. Shes for real...looks  just like her pics and has some real film credits under her belt.  If she is here when you are she might be worth considering.  I saw her several years ago and found her to be a lot of fun.  Hope this helps.
