A.S.F.R. animations can be hard to find, but this is an unusually fine one. The tumblr where I found it originally contains this caption:
The white slave enjoys one final orgasm as the copper infusion transforms it into a statue, an objet d’art…
The animation is reblogged from this 26 November 2015 post at Infernal Wonders.
Powerful image… quite the way to go.
