Now this is something you don't see every day, a custom metal suspension piece. This is what happens when ART hits BDSM in the face with a creative stick.
This position in itself is torture on a beautiful level. The arch, the strain of the back, the helplessness of of the victim. The huge breasts exposed, nipples popping out and straining, clamped and weighted. Her feet are exposed to caning and snapping. This is agony in its most attractive form. No hope for pleasure, just a slow suffering...
