Any ideas on providers who are good at domination and GFE? I have had some success but find that often the domination is rather perfunctory. I am interested in recommendations for someone in the city who can really take charge of a session with a firm hand and doesn't require direction. Thanks

Check out Amazing Asia. I think she is exactly what you are looking for.

She's African American, not Asian, 5'10" in bare feet, offers terrific GFE service but has a dominant side and specializes in sensual domination. She also has a trunk full of toys and knows how to use them. Here's a link to her reviews:

Rene/Liz also provides a fantastic sensual domination GFE session, but she's not in town at the moment.
