Unfair!

Master wants me to drink from the bowl? But I'm gagged! So unfair!

Master better have a really delicious punishment in mind for this!

Image source: A multi-site reverse image search found this image on several big aggregator sites, but with no attribution. But I did find another photo of the model from the same pet bunny set on my computer that said the model was Morgan Leigh. So I'll tentatively identify the model as Morgan Leigh, as there is a porn model who has done bondage modelling named Morgan Leigh out there. 

The one thing that keeps the identification tentative is that I could not get any hits from this photoset via a text search on Google. Generally, once you have the model's name and a few keywords, such as pet bunny, nude, ballgag, collar, leash, you can pull up an image from the photoset pretty easily, if there's any out there. And the fact that the image was found on a couple of big aggregator sites generally means it's well represented on the Internet. But no luck. So, this is tentatively Morgan Leigh. If anybody knows differently or can identify the originating website or photographer, please sing out in the comments.
