'IneedRubbin' - that's my old buddy's technique. Personally, I find that to be a little too direct, although I did try it once, with good success. I usually do what 'Lshue27' does on his #1. I'll wiggle my buttocks when she starts to move her hand up the thigh and moan softly. They'll definitely catch the little nuances. If they want their tip, they'll offer something, it's all understood that "no extra, no tip" - although I had to re-educate a few girls from past experiences.
There are some exceptions when I knew I was only in there for a massage, that she did great at. Knowing the legitamate ones and the naughty ones (or however you want to describe it all) comes with time.
If you still get confused, make sure you have a VIP on this site, and find the
MP places that offer the
HJ (hand jobs),
BJ (blowjobs) and
FS (full service). There may be limits on how much service management will allow.">extras.
