anyone have any experience with mystique escorts?

Yes and they suck. I wouldn't repeat.

They look like they were picked up at a bus stop.

She was pretty good, let me explode all over her face...I saw her on her own time after that until I got tired of her.  As far as the other girls I never tried them but I hear that the agency as a whole is not very good.  The first time I saw Julie she was over 2 hurs late and the phone girl was nasty as hell.

The phone girl is extremely rude and makes you play roulette by having you check in until the girl you select is available. She chooses not to call any clients herself. Imagine that, a phone girl who won't make phone calls. Trust me, this agency sucks and btw, when I finally picked out a girl, she had a very bad attitude. This is one agency you definitely want to stay away from.
