I believe....

She is a CSI checking for organic material as she enters an outcall.

I would put your odds at less than 50% that its not her real photos just based on the outcall only option.  My batting average with unknowns for outcall has been far worse and I rarely do that anymore without a meet and greet prior to the date.  But then, even the ones with fake photos sometimes are just as hot anyway and things work out ok.
