I wouldn't hesitate in recommending GracieXXXDevon, she's stunning and makes you feel genuinely welcome. I've seen her loads of times, with her in the role of dom, and I'd happily be at her mercy all day every day if money was no object. I'm planning my next visit to her as my birthday treat to myself. She's not just a dom though, she also provides vanilla services, and I have no doubt she'd be exactly what you're looking for if you're that way inclined.
