Not sure what part is supposed to be nsfw, but interesting concept so far. I would like a reference to him being a dog/wolf creature earlier than you did, because other than the cover image, for the first several paragraphs, one could assume he was a pig/boar, or something different.
I mostly put it there as a disclaimer- innuendo and such...Thank you for bringing that to my attention, I'll try and get it fixed as soon as possible :)
