Even though the busses are normally on time, they were running late that day and Alex and Jan were hoping to at least make it to their shopping center on time to use the cubicles. It was a long ride and neither of them could hold off peeing for longer. With no other options and already being in public, pissing was the only way to get a relief. When one started the other one followed, and while happy not to be so stressed out, the transport arrived. Hand in hand both Alex and Jan both walked home with their trousers and backs covered in piss.
