Depending on what kind of BJ you are after:
Emily Blonde - Excellent deepthroat skills done in a very sensual way
Isla Brooks - More Raunchy and porn star like, plus she will swallow
and one I reviewed recently
SexualRosie - Not a WM resident, but she does visit, full on face fucking, gagging deepthroat. I spent an hour pretty much the whole time with my cock down her throat, very messy, but one of the dirtiest BJ's I have ever had and very specialised CIT finish.
