/r/DirtySmall is a subreddit committed to providing you with images, videos and GIFs of a hardcore nature that features small chicks getting dirty. The rules are pretty simple here: you show the creme de la creme of petite porn action and do so in an easy to access fashion. Dirty Small is a great place if you're a fan of tiny chicks getting used and abused in front of the camera.
The subreddit has just a few guidelines, namely submitting direct links, no reposts and hardcore contact being required. The moderators seem to have a tight grip on the submissions and the content on the homepage is definitely what I'd consider to be relevant to my interests.
/r/DirtySmall updates with new content on a pretty limited basis, sadly. Although there's over 100,000 readers, there are only one or two people that regularly submit fresh releases. Still, the subreddit has been around for ages, so you can easily go back through the submissions and find good quality petite porn content.
