To browse through different private shows, you can click on the "Private Shows" tab to see a list of broadcasters currently in a private session. If you're interested in checking out what's happening in a private show on a broadcaster's cam, just go to their profile and click on "Spy On This Private Show."
Keep in mind, some broadcasters might require you to have a minimum number of tokens before you can start spying on their show. Once you're in, you'll be charged a set number of tokens per minute to continue watching.
