Secretly We're All Perverts

If an attractive person came up to you at a grocery store and asked if you would like to go to their car for a quick, discreet orgasm (like oral or a hand job), how likely are you to say yes?

If you are attractive and made the offer to a complete stranger, how often do you think they would accept? I really believe that most people have a "random encounter" fantasy, but are too nervous to initiate one. But if the situation was right, most of us would be down for some anonymous fun.

Have you ever done this?
