Works by the artist Buta99. Contains anthro chicks with big butts and big boobs. I think his newer stuff is significantly better than his older stuff.
The artist only posts to Twitter, so please forgive any image compression or poor quality.
There was another gallery updated/uploaded just yesterday for this artist, but that only had about 200 images. I think the uploader for that gallery just scraped e621 instead of the artist's Twitter profile directly. This gallery has every picture the other one did (with the exception of a couple futanari pictures), plus several hundred pictures that were not uploaded to e621.
