Truth is that the ad looks like every other AMP/AAMP/Escort service ad. It promises beautiful, young Asian gals fulfilling your wildest desires, and provides pics of hot gals that you will never find in their employ. Even the "No sex" places, like Massage Inn, use this tactic.
There have been several of these Services in the Plano area. Likely, it is just like them. You will go to a house/condo/apt with little/no furnishings. There may be several gals there. You will get a gal that is younger & cuter than the average AMP. She will speak little/no English. She will follow a routine. Any attempts to convince her to change the routine will be frustrated by her lack of communication ability. Her performance will likely be less than impressive. But, if you are lucky, you will get the one that really likes what she does and improvises.
So, is this one LE? Probably not. But, until someone TOFTT, we will not know.
