I haven't tried the McKinney area but from ECCIE reviews and other sites that would be hard to find. You may try a independent provider in the area, or head farther south.
Lexi4YourFantasy (P411 ID is P91344) just moved a bit south to Allen and is a bit expensive (just raised her rates) but offers this service. See her website for details/menu and specials re her new incall: http://sexylexi4you.escorts.biz/
