On a passing car

The traveler spots a car approaching him from up ahead, and drives slow enough for the traveler to aim his cock in the direction of the road. His stream of piss starts spewing forth just in time to splash all over the front windshield, and in an instant the car comes to a screeching halt. The travelers stream is interrupted as he fears he have been mistaken about how accepting this society is of perverse urination, but his fears are quelled when a topless woman rolls down the passenger window and puts on a display for the traveler. She sticks her body out the window and begins groping her tits and sucking on them as she presses her exposed pussy on the bit of window glass that remained rolled up. As the traveler stared, she began pressing her pussy harder and harder against the glass until she began urinating directly onto the glass. The piss strayed past her and drizzled down the window and onto her thighs as the traveler stood enthralled by the hot display before him. As her stream died down, she blew the stranger a kiss before crawling back inside the car, and speeding off down the road.

Because your piss was interrupted, you still need to pee, even more so than you did before!
