I was sunbathing on the river at Penrith Australia in a G-string only and I thought i was the only one who knew about this spot and after a few hours i could hear voices and I went for a walk along the river and then I come across 2 guys and 2 women getting out of a boat.one of the guys saw me and he told his mate and they called out to me and they said wait there .I'm in a G-string and singlet and they come up to me and they say hello and one of the guys said that he saw my ass cheeks in my G-string and told my mate.he said that if you would like to get on or boat and he asked me if I was some kind of slut just curious I said yeah I am a slut and he said are you keen to come for a boat ride with us maybe you can show us how slutty you are.
