Sweet And Kinky

So a while ago I found this image in this image thread that was looking for fanart of the rising manga star Monster Musume no Iru Nichijou (also known as 'My Life with Monster Girls) in addition to any other monster-girl themed pictures people might have.  A google image-matching search cites this as the image's only known online location and the person who posted it is, as per usual of the hosting site, anonymous.  In short I'd love to credit the original artist for a well executed image, but they remain a mystery.  I'll state again, for the record, I did not create the original source material, but I did do some moderate editing and animation with Photoshop; specifically changing the tops on both characters to cropped open-vests and added a belly-chain with coins to the lamia(naga?).  
I have another version of this where she's gyrating a bit faster, but I wasn't sure if people were interested in seeing 2 versions of basically the same animation.  So hey, if that peeks your curiosity, leave a comment about it, and I'll make it happen.

If the creator of the original source material happens to see this, please make yourself known.  I would love to congratulate you on a fine piece of artwork.  They're a really cute couple.
