I originally blogged this illustration, “Cross Species Breeding Program 1,” by longtime friend of the site KristinF in this 14 March 2016 post at Infernal Wonders. This version, kindly provided by the artist herself, is the extra-explicit version that could not appear at Tumblr even before Tumblr went prude or even at the artist’s DeviantArt site. Thanks for the art, KristinF!
You can click and download to see the image in all its icky goodness.
