Not a provider, but a civvie GF. BBBJ while I was driving down the highway and decided I needed to concentrate on the important issues, so I pulled into a truck rest stop to give her some operating head room, so to speak.

It was in a little Datsun (yeah, it was a while ago) B-something-or-other and turned into a full-fledged fuckfest parked between a couple of semis. On the way home I had to pull off the road again into a school parking lot.

Not the most public of events, but a good memory.

LOL, does picking up a street walker and getting a blow job behind the police station count?

I've done it plenty of times in public pre-providing.... ha sounds like fun.
