Here's the image in question.

I checked IQDB with no avail, it led me to look at google images, saucenao and tinyeye. Nadda.

Looked here using tags:
Solo
Feline
Looking_at_viewer
Tied_up
Chains
And a variation of those, and wasn't able to find anything.

The artist sig is barely visible, so if anyone has any idea, it would be greatly appreciated.

If you don't have any luck with those, that means it's probably on furaffinity (google doesn't get images off furaffinity). Which is unfortunate because seeing as that is an extremely common species, narrowing down the results is a bit of a crapshoot. The best I can go off of is that it looks like KH to me (though that might be a 4, i'm not sure) and the image was drawn in 2014, which narrows it down a bit, but not much. It's possible that it was a commission or the artist doesn't actually want to be found, but that's another story.

I tried looking for it elsewhere but I don't recognize the signature or style enough to know where to look on furaffinity, and a few searches didn't really seem to narrow it down much.

would be nice if there was a way to cut/paste the artist sig from pics and do a search for that. that aside, i did a quick reverse search on google and nothing came up but tumblr, tumblr everywhere (mainly reposting i guess). maybe if i knew which tumblr it originated from, that might help.

I kept seeing it attributed it "Kitty Femboy". They all seem to lead back to this post eventually: http://kittyfemboy.tumblr.com/post/113721475949/3

But that post does not site its sources, and also was posted in 2015, not 2014, as the year on the signature would suggest, so there's got to be something older...

If it is on Furaffinity, it is improperly categorized, because I looked through a large number of images and couldn't find it in the 2014 year time frame.

So yeah. It seems some guy posted it unattributed on tumblr, and everyone else has been just linking to that set of images. At this point I'm out of ideas, unless someone wants to message the original tumblr poster.

Everyone on the Interwebs needs to see this:

If people didn't look at me weird I might tattoo this on my back.

ty for pointing out the first thing i do for such pic related searches. unfortunately, what i spoke of above often happens with pics in this type of thread so google isn't all that reliable. in fact, all the search engines you see as links on pics here are about equally useful as each other from what i've seen while using them. usually

something else that is far more rare is an actual relevant/useful pic appearing in google's "visually similar" section at the bottom of the search results (and i mean those results are RARELY relevant at all).

also, judging by that tumblr page, i'm going to guess that this "kittyfemboy" is the artist (or a hardblush artist at least) and that it might be a pic from the hardblush site but i'm not sure since like before, i can only seem to find that and other tumblr's that have reposted those pics.

Strategies for finding sources:

Deviantart/tumblr: Reverse google search
Pixiv: https://saucenao.com
Inkbunny: Search using md5 hash (or just use eSix extend)
e621: https://iqdb.harry.lu
Pony stuff: https://derpibooru.org/search/reverse
Doujinshi: google site:doujinshi.org + name of comic/artist

ah, can't say i do any better on that one (note: tags/keywords are just that, not a place to write out a description, people. that's what the description space under pics are for. *facepalm* that's why FA's search function sucks big time.)

Someone could go through this list and see if the signature appears anywhere:
https://e621.net/tag?name=k*_h*&type=&order=name

And yes, a signature archive with a "search by signature" function would be a great thing.

I did that already with k* and find->h just in case there the tag didn't have an underscore. The closest signature-wise was kelly_hamilton. However even if that were the artist, it doesn't look like they want to be associated with the more adult art that they've made (I also don't think they are the same artist).
