Original artist: Sterks (FA) / ArtsySterks (Tumblr)
This is part of an overall series of variants on one picture--I wanted someone to draw a featureless nude base image and then put clothing over it (so I had clean/SFW references,) and then go back and add both sets of genitalia to the nude one for NSFW purposes. I'm... curious how certain configurations look/feel, you see. This is how furries experiment with gender.
Sterks is that person, and I couldn't be happier with the results. :D
(Note that the Celine canonically still has the traditionally male equipment and that the alternate versions are just hypothetical what-ifs, but also note that she still identifies as female regardless!)
