There's a lot of focus on girls who are really good at blow jobs but here and there, I'm in the mood for a sensual slow handjob with some dirty talk.  I've been to a few of the girls at the private viewing agencies and it's very hit and miss and most aren't actually talented in hand jobs.  Just basic stroking until you come.  On some of the porn sites, you see really talented erotic hand jobs by hot women.  

Any recommendations on girls who are really good at hand jobs and seem to enjoy making guys come this way?
