I've used this agency a good deal, so booking is easy. They have locations in DC as well as in the VA suburbs, and the girls rotate to different locations. There are Chinese and Japanese girls, each with different characteristics. Lingba is Chinese, a little bit older than some of the ingenues, but sexier as a result: think Gong Li in her 1990s films, such as Farewell my Concubine.
Set up by text; location is a condo / apartment complex in a gentrifying part of DC, parking not impossible, near mass transit. Suburban locations all have easy parking. DC building and elevator access by code, which agency sends. An aunty answers apartment door, manages guest arrivals. Lingba met me in the door to her room in a tight red mini-dress, very flattering to her slim but curvy figure.
