What I find is a lot of lasses stop wanking you once you start to cum, personally I want them to keep stroking right over the end until I'm finished, after all in full sex you don't pull out as soon as you start to pump, you keep banging away, and a good handjob should simulate penetration. The only girl I ever knew who seemed to understand this was a WG in the massage parlour in Billingham, she changed from fast strokes to long slower ones once the cum started spurting and the effect was mind blowing.
