I've been ambivalent about Devilish in the past, having met some very nice young ladies from there as well as my all-time least-favorite (review posted 2 years ago). However, I'm a plan-ahead sort of guy and my wife made a majority of her recommendations from that family of agencies. I've learned to trust her instincts since, apparently, she sees totally different things in the pictures than I do.
Anyway, I followed the instructions to call in the morning as described in the posting but didn't have any particular hopes. Imagine my shock when I did actually get a call back not at all long afterward. None of the girls I wanted to book were scheduled but he said he'd "see about it and call back." Big surprise. No, really - he did call back and offered me an appointment with one of my top choices and said he'd work on the others. I've now seen a second and a truly superb third. I have every confidence that he'll keep working over the next few days to keep me supplied with the wife calls "top-shelf totty."
I'll post reviews on the actual encounters once I've had a chance to let the blood get back to my brain, but wanted to take the opportunity to post my thoughts about this pre-booking system and how it's been working for me.
