There are a number of special interest groups on Reddit where people post pictures of interest here. The two main ones I check out are:
https://www.reddit.com/r/peegonewild/
https://www.reddit.com/r/Pee/
There are new posts on these every day of mostly chicks showing themselves. Format is similar to a Facebook newsfeed. Content is both stills and short videos. Most of the content is hosted here:
https://www.redgifs.com/
That site is searchable.
Happy hunting!
