This is a little late, but...

I used the Silicone Slims Self-Satisfier with my girl recently. We went out to eat with it in its special place. The controller was tucked into her pocket with her shirt covering the evidence. It was turned on for a while, and then turned off... over and over throughout the meal.

As the description on the web page clearly states, this isn't going to provide an earth shattering orgasm, but it is extremely quiet, is quite pleasurable, and did what I wanted.
