Hints or just Play?

First, let me set the scene. You are in a topless club, enjoying a dance from a hot dancer and she is giving you a LOT of "up close and personal" looks at her g-string covered pussy, and every time she reaches down and rubs her pussy through her g-string, knowing that you are watching every little movement those finger are making. She's got her crotch so close that your nose is picking up her scent.

This happens all of the time, but until recently, I just thought this was another way that the girls use to entertain. My current fav was doing this during our last session, to the point that she picked up the pace and was really going at it. Normally, I wait until the girl guides my hand to where she is giving permission for it to travel, but this time, as it seemed she was gettin' herself off, I think I'd join in and give her a helping hand. Surprisingly, she was receptive of it, and actually allowed me to "push my limits" (even though it's typically against my philosophy) and worked my fingers underneath and inside her g-string. Definitely a nice surprise!

Sooo... my question to you with more experience, was this finger play of hers initially a means of entertainment, or was this an invitation for me to get inside?

If it was a hint, Have I been missing these hints from girls for YEARS? (if so, maybe I need to re-think my philosophy!)
