Gone Wild Curvy is a subreddit where users of the site are allowed to share images of themselves in sexually suggestive poses for the purposes of luring members of the site to give in, post comments and show Reddit that they're all secretly chubby chasers. With 140,000 subscribers, /r/GoneWildCurvy is one of the larger subreddits out there that deals with adult content. Note that all of the submissions are done by the girls featuring in the content itself - this is 100% amateur stuff with some fine chunky chicks getting nude and rude for your viewing pleasure.
The subreddit currently updates with fresh material about 60 times a day - that's all girls who are thick and looking for a little bit of loving too! There are quite a few rules for submissions and while it might be tight on how to share your content, the results speak for themselves. In my mind, this is one of the best places on the Internet for real amateur curvy porn.
