Amethystine asked me earlier to have a look at his first try at a commercial story and maybe do a bit of a shout out.
In my opinion good transformation artists and writers always deserve support, so I think people should have a look at it.

This leads to his own journal with a link to the story: http://www.furaffinity.net/journal/7871323/

The story is nicely written and focuses primarily on the theme of cocksnakes, people turned into serpentine penises of others.
Who doesn't like a bit of CTF. :)
