At the beach on a hot bank holiday, I was up walking along the sandunes which were behind a sandy beach. A young woman in her 30s and her partner appeared in front of me , walking in same direction. They went over a hump out of site and I reached the point a few minutes later to be greeted by the woman with her tailored white shorts and panties around the knees peeing. She sqealed to her partner who was some distance away when she saw me to "help me". He said how can I. she carried on peeing as a I walked behind her with her bare arse and pee hitting the sand. .
