I piss in a public park first dressed then naked

I'm in a public park and I need to pee. I move from the path to a wall of the park to be less visible to passersby, while my brother starts taking pictures of me. I lift up my mini-dress and squat down to pee then he takes off my mini-dress to take pictures of me naked while I continue to pee. A group of black guys saw me peeing dressed and then naked and approached me. They called me "beautiful whore" and wanted to have a gang bang with me. But my brother stopped them saying that I was a porn star and we were doing a photo shoot in public, so they could watch but not get in the way of the shoot
