Things that are better than regular still images are definitely .gifs, especially if they include nudity like at reddit.com/r/nsfw_gifs/. You will be able to find all sorts of .gifs on this website, and most of them are going to be submitted by the users who are amateur babes that seek attention from other users who are registered on Reddit. Of course, there are also posts of pornstars in action, which makes this subreddit even better, because it never hurts to have more naked babes in action.
There are loads of .gifs uploaded every day, and if you would not like to go through the “bad” ones and only see the top rated of the day and the days before, all you have to do is browse the hot page because that is the page with the most posts who have incredible upvoted feedback.
