Have you ever tried eros-ny.com?
1. Enter Manhattan into the "search terms" area
2. Click New York into the "city" area
3. Unless you have a preference between TV & TS click all
4. Set viewing to 90 because I believe the listing for girls right now is well over 100
I don't know if you have a special preference regarding ethnicity like I do (the two you mentioned are Asian [Venus] and Caucasian? [Jessy/Mistress Kang] respectively) but the top black tgirl recommendation I would make in the city this week (August 31, 2008 - September 6, 2008) are...
(Apologizing in advance as I don't know how to attach their pics)
1. Egypt/Diamond -
www.egyptsxxx.com (10" cock length, tall, cute face, slim waist, nice ass)
2. Jackie O'Nasty/Trinity Treat - no website...doesn't like too much exposure although her close friend is Natasha Coxxx who loves exposure...I wonder if that's common among other girls? (9" cock length, short, cute face, slim waist, nice ass)
3. Sweet Cream/Kayla - no website...Appeared on BTG as Kayla in the model of the month section September 2007 (9" cock length, average height, VERY Cute Face, slim waist, her implant job looks pretty good)
Hope this helps!
