In the wide world of Hentai, there are just too many fetishes to list, and some of them can be a little strange.
One of them is called 'Goo Girls', and it features images of women composed entirely of jelly, slime, or some such 'gooey' substance.
Here is a link to a site dedicated to such: Goo Girl Hentai
This is not my particular kink, but it did spur my imagination enough to try my own version of a 'goo girl'
I used a 'candle wax' texture for the skin, making it a bit transparent, and within that figure another that had a 'solid glass' texture to provide some light refracting.
I do like the way it came out, although I probably should have added more 'drippy bits' by using some of my 'money shot' props (maybe for next time )
